Abstract

A display housing includes a first housing part including a plurality of first engaging members, a second housing part including a plurality of second engaging members, and a plurality of interlocking members, each of which is snappingly and detachably connected to and interlocks a respective one of the first engaging members and a respective one of the second engaging members. Engagement of each interlocking member with the respective first engaging member prevents relative movement between the first and second housing parts along directions of a first axis of a Cartesian coordinate system, along directions of a second axis of the Cartesian coordinate system, and along directions of a third axis of the Cartesian coordinate system. The first, second and third axes all being perpendicular to one another.

Claims

1. A display housing adapted to accommodate a display panel, the display housing comprising:

a first housing part comprising a plurality of first engaging members;

a second housing part comprising a plurality of second engaging members; and

a plurality of interlocking members, each of which is detachably connected to and interlocks a respective one of the first engaging members and a respective one of the second engaging members so as to secure the first housing part to the second housing part such that the first and second housing parts cooperatively define an accommodating space therebetween capable of accommodating the display panel therein.

2. The display housing of claim 1, wherein each of the interlocking members is engaged with the respective one of the first engaging members and the respective one of the second engaging members in a snap fit engaging manner.

3. The display housing of claim 1, wherein the interlocking members have a breaking strength less than that of the first and second engaging members.

4. The display housing of claim 1, wherein the first housing part comprises a first peripheral wall on which each of the first engaging members is formed, and the first housing part further comprises a lug wall, the lug wall protruding from the first peripheral wall into the accommodating space and defining a hook hole, wherein each of the interlocking members includes at least one cantilever comprising a hook end engaged in the hook hole in the lug wall of the respective first engaging member in a snap fit engaging manner, and wherein the at least one cantilever of each of the interlocking members has a breaking strength less than that of the lug wall of the respective first engaging member.

5. The display housing of claim 4, wherein the second housing part comprises a second peripheral wall, each of the second engaging members being formed on the second peripheral wall of the second housing part and having a lip protrusion protruding from the second peripheral wall of the second housing part into the accommodating space, each of the interlocking members further including a base plate comprising a hole, the at least one cantilever extending from the base plate, the lip protrusion of each of the second engaging members engaged in the hole of the base plate of the respective interlocking member in a snap fit engaging manner, and the base plate of each of the interlocking members having a breaking strength less than that of the lip protrusion of the respective second engaging member.

6. The display housing of claim 1, wherein the first housing part comprises a first peripheral wall, each of the first engaging members being formed on the first peripheral wall of the first housing part and having two opposite lug walls and an interconnecting wall, the lug walls protruding from the first peripheral wall of the first housing part into the accommodating space, the interconnecting wall interconnecting the lug walls and cooperating with the lug walls and a portion of the first peripheral wall of the first housing part to define a slot, each of the lug walls defining a hook hole in spatial communication with the slot, each of the interlocking members having a base plate and two opposite cantilevers extending from the base plate, each of the cantilevers having a hook end, the cantilevers of each of the interlocking members being received in the slot of the respective first engaging member, and the hook ends of the cantilevers of each of the interlocking members engaged in the hook holes of the lug walls of the respective first engaging member in a snap fit engaging manner.

7. The display housing of claim 6, wherein each of the lug walls of each of the first engaging members comprises an end defining a shoulder, each of the cantilevers of each of the interlocking members cooperating with the base plate to define an elbow, the elbows of each of the interlocking members engaging the shoulders of the lug walls of the respective first engaging member, respectively.

8. The display housing of claim 7, wherein each of the interlocking members further comprises a limiting plate extending from the base plate and being disposed between the cantilevers and received in the slot, the limiting plate of each of the interlocking members having two opposite sides and being substantially in contact with the interconnecting wall of the respective first engaging member and the first peripheral wall of the first housing part at the two opposite sides thereof, respectively.

9. The display housing of claim 8, wherein the limiting plate of each of the interlocking members is generally U-shaped and comprises two opposite arms, and each of the interlocking members further comprises two opposite reinforcing ribs on the base plate respectively connected to the arms of the limiting plate.

10. The display housing of claim 6, wherein each of the interlocking members further comprises two opposite reinforcing ribs on the base plate, and a limiting plate extending from the reinforcing ribs between the cantilevers and being received in the slot, the interconnecting wall of each of the first engaging members defines a hook hole, the limiting plate of each of the interlocking members comprises a hook end that is engaged in the hook hole of the interconnecting wall of the respective first engaging member in a snap fit engaging manner, and each of the cantilevers of each of the interlocking members is substantially in contact with the peripheral wall of the first housing part.

11. The display housing of claim 1, wherein the first housing part comprises a first peripheral wall, each of the first engaging members is formed on the first peripheral wall of the first housing part and comprises two lug walls and an interconnecting wall, the lug walls protruding from the first peripheral wall of the first housing part into the accommodating space, the interconnecting wall interconnecting the lug walls and cooperating with the lug walls and the peripheral wall of the first housing part to define a slot, each of the lug walls having an abutting end and a notch defined in the abutting end and in spatial communication with the slot, each of the interlocking members comprises a base plate and two opposite cantilevers, the base plate comprising an end from which the cantilevers extend, and the cantilevers of each of the interlocking members being received in the slot of the respective first engaging member, with a portion of the base plate of each of the interlocking members received in the slot and the notches of the lug walls of the respective first engaging member.

12. A display housing adapted to accommodate a display panel, the display housing comprising:

a first housing part comprising a plurality of first engaging members;

a second housing part comprising a plurality of second engaging members; and

a plurality of interlocking members, each of which is snappingly and detachably connected to and interlocks a respective one of the first engaging members and a respective one of the second engaging members, wherein engagement of each interlocking member with the respective first engaging member prevents relative movement between the first and second housing parts along directions of a first axis of a Cartesian coordinate system, along directions of a second axis of the Cartesian coordinate system, and along directions of a third axis of the Cartesian coordinate system, the first, second and third axes all being perpendicular to one another.
