Description
Technical field
The utility model relates to a kind of testing table, especially relates to a kind of brake switch endurance test bed.
Background technology
The automobile brake switch is from initial single loop, and two-circuit till now is from single Brake lamp loop; Till now brake priority system and automatic cruising system, brake switch is more and more important, loses efficacy if brake switch occurs; Cause that Brake lamp does not work, cruise function lost efficacy, and was prone to give the vehicle at rear to cause illusion, can cause traffic hazard in the time of seriously; Therefore for guaranteeing the quality of brake switch, must carry out the test of switch life to brake switch.
For example, Chinese patent Granted publication number: CN2572394Y discloses the testing machine in a kind of Test Switchboard life-span September 10 2003 Granted publication day, and it comprises board main body, switch module and slide plate, and the board main body comprises a plurality of control knobs and a counter; The switch module comprises a tool, on tool, is provided with at least one micromatic setting; Slide plate is slided by cam driven; During use; Switch to be tested is arranged on the switch module; And, seeing through the knob of tool platform again through micromatic setting adjustment switch key relative position, adjustment is with respect to the distance of slide plate; By the cam driven slide plate do towards or deviate from the reciprocating action of switch key, with the life-span of this Test Switchboard.Its weak point is that this tester architecture is complicated, uses also very inconvenience.
The utility model content
The utility model is complicated in order to overcome existing testing machine structure, and awkward deficiency provides brake switch endurance test bed a kind of simple in structure, easy to use.
To achieve these goals, the utility model adopts following technical scheme:
A kind of brake switch endurance test bed of the utility model comprises test platform, also comprises direct current generator, display, counter, braking pilot lamp, the control module of being with gear; Described test platform is provided with the switch mounting bracket; Described switch mounting bracket is provided with brake switch, also is provided with the tooth bar mounting bracket on the described test platform, and described tooth bar mounting bracket is provided with tooth bar; Described brake switch contacts with an end face of tooth bar; Described brake switch is connected with the braking pilot lamp, and described direct current generator is meshing with each other through wheel and rack, the direct current generator link control module; Control module connects braking pilot lamp and display, described counter link control module and brake switch.
The utility model meshes through the wheel and rack on the dc motor shaft and drives tooth bar and push brake switch, drives tooth bar with direct current generator, and is simple in structure; And push velocity ratio and be easier to control, through pushing brake switch, feasible braking pilot lamp is lighted or is extinguished; Counter records cycle index, control module are constantly carried out current transformation, make that direct current generator can forward or reverse; Thereby tooth bar is constantly moved in circles push braking light switch, damage, if control module can not get the Brake lamp signal until the contact; Then control module automatic cutout, the cycle index of recording counter and last automatically through the display demonstration.
As preferably, described tooth bar is provided with the switch spacing hole that matches with the surface of contact of brake switch, and spacing hole makes tooth bar when pushing brake switch, has both played guide effect, can prevent that again brake switch is subjected to displacement.
As preferably, described brake switch is the push button composite contact switch with normally opened contact and normally closed contact, and push button composite contact construction of switch is simple, and just in time cooperates with tooth bar and push.
As preferably, described braking pilot lamp comprises the indication red light and indication green light of parallel connection, and described indication red light connects the normally closed contact in the brake switch, and described indication green light connects the normally opened contact in the brake switch.
Therefore, the utlity model has following beneficial effect:
(1) simple in structure, easy to use;
(2) rotating speed of scalable motor is tested the switch endurance under the different compression frequency.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
In Fig. 1, embodiment shown in Figure 2, a kind of brake switch endurance test bed comprises test platform 1; Also comprise direct current generator 2, display 3, counter 4, braking pilot lamp, the control module 5 of being with gear; Described test platform 1 is provided with switch mounting bracket 6, and described switch mounting bracket 6 is provided with brake switch 7, also is provided with tooth bar mounting bracket 8 on the described test platform 1; Described tooth bar mounting bracket 8 is provided with tooth bar 9; Described brake switch 7 contacts with an end face of tooth bar 9, and described tooth bar 9 is provided with the switch spacing hole that matches with the surface of contact of brake switch 7, and described brake switch 7 connects the braking pilot lamp; Described direct current generator 2 is meshing with each other through wheel and rack 9; Direct current generator 2 link control modules 5, control module 5 connects braking pilot lamp and display 3, and described brake switch 7 is for having the push button composite contact switch of normally opened contact and normally closed contact; Described braking pilot lamp comprises the indication red light 10 and indication green light 11 of parallel connection; The normally closed contact that described indication red light 10 connects in the brake switch 7, the normally opened contact that described indication green light 11 connects in the brake switch 7, described counter 4 link control modules 5 and brake switch 7.
