Abstract

An apparatus and method for testing vehicle motor rotary accessory devices has a base and a housing assembly connected to the base. A mounting component is attached to the base. The apparatus includes a door cover which is rotatably attached to a side of the housing assembly and the mounting component. A switch assembly is mounted to the mounting component and positioned to contact a portion of the door cover when the door cover is rotated to a prescribed position.

Claims

1. An apparatus for testing vehicle motor rotary accessory devices, comprising:

a base;

a housing having at least one side surface, wherein the housing is connected to the base;

a first component located and connected to the base;

a door cover located and rotatably mounted between the at least one side surface and the first component; and

a switch assembly mounted to the first component and positioned to contact a portion of the door cover when the door cover is rotated to a first position, wherein the switch assembly is not contacted by a portion of the door cover when the door cover is rotated to a second position, wherein the door cover further comprising a tab portion which contacts the switch assembly when the door cover is rotated to the first position and wherein the switch assembly further comprises a micro-switch having a flexible lever device which is designed to contact a trigger button.

2. The apparatus according to claim 1, wherein the tab portion contacts the lever device to deflect the lever device against the trigger button such that the trigger button is depressed when the door cover is rotated in the first position.

3. The apparatus according to claim 2, further comprising powered internal components of the apparatus for testing, wherein power to one or more components is interrupted when the switch assembly is not contact by a portion of the door cover when the door cover is rotated to the second position.

4. The apparatus according to claim 3, wherein the one or more components comprises a motor and a transformer.

5. The apparatus according to claim 1, further comprising a digital signal processor (DSP) coupled to the switch assembly.

6. The apparatus according to claim 5, wherein the DSP controls power to one of more of the components by monitoring a state of the micro-switch.

7. The apparatus according to claim 6, wherein the DSP generates an error message and displays the message to a user when power is interrupted.

8. A method of implementing a safety mechanism in a testing device for vehicle motor rotary accessory devices, comprising:

providing a base component and a housing component connected to the base component;

locating and connecting a first component to the base component;

locating a door cover between a side surface of the housing and the first component;

rotatably attaching the door cover to the side surface and the first component;

mounting a switch assembly to the first component; and

positioning the switch assembly to contact a portion of the door cover when the door cover is rotated to a first position, wherein the door cover further comprises a tab portion which contacts the switch assembly when the door cover is rotated to the first position and wherein the switch assembly further comprises a micro-switch having a flexible lever device which is designed to contact a trigger button.

9. The method according to claim 8, further comprising:

rotating the door cover to a first position;

contacting the tap portion of the door cover with the lever device; and

deflecting the lever device against the trigger button to depress the trigger button.

10. The method according to claim 9, further comprising:

rotating the door cover to a second position; and

releasing the tab portion of the door cover from contact with the lever device.

11. The method according to claim 10, further comprising:

coupling a digital signal processor to the switch assembly; and

monitoring a state of the switch assembly.

12. The method according to claim 11, further comprising:

interrupting power to one or more internal components of the testing device when the tab portion of the door cover is released from contact with the lever device.

13. An testing apparatus for testing vehicle motor rotary accessory devices, comprising:

a base means for supporting the components of the testing apparatus;

a housing means having at least one side surface, wherein the housing means is connected to the base means;

a first component means located and connected to the base means;

a cover means located and rotatably mounted between the at least one side surface and the first component means; and

a switch assembly means mounted to the first component means and positioned to contact a portion of the cover means when the cover means is rotated to a first position, wherein the switch assembly means is not contacted by a portion of the cover means when the cover means is rotated to a second position, wherein the cover means further comprising a tab portion which contacts the switch assembly means when the cover means is rotated to a first position and wherein the switch assembly means further comprises a micro-switch having a flexible lever device which is designed to contact a trigger button.

14. The system of claim 13, wherein the cover means comprises a door cover.

15. The system of claim 13, further comprising powered internal components, wherein power to the internal components is interrupted when the switch assembly means is not in contact with a portion of the cover means.
