Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below by combining the specific drawings.

As shown in fig. 1, the present invention provides a key pressing actuator, which includes a supporting base plate 310, a key holder 320 disposed on the supporting base plate 310 for fixing a key 500 to be detected, and a key button pressing mechanism 330 disposed above the key holder 320. The key button pressing mechanism 330 includes a pressing lever support 331 disposed above the key holder 320, a self-resetting key pressing lever assembly 332 disposed through the pressing lever support 331, and a pressing mechanism 330 for pressing the self-resetting key pressing lever assembly 332 downward to press the key button downward.

As shown in fig. 2, a key placing groove 321 recessed downward is formed in the key holder 320 for placing a key, the shape of the key placing groove 321 matches with the key 500 to be detected, and an opposite surface of the key 500 to be detected can be placed in the key placing groove 321 in a matching manner. As shown in fig. 1, a key clamping block 322 screwed with the key fixing seat 320 is respectively disposed at the front and rear of the key placing groove 321. Two the key clamp splice 322 is the relative arrangement, every the draw-in groove (not shown in the figure) has all been seted up with the contact surface that detects key 500 contact to key clamp splice 322, and two draw-in grooves are equivalent to the centre gripping part of mutually supporting, cooperate together with key standing groove 321 to will detect key 500 and lock, avoid becoming flexible, influence and detect.

The pressing rod support 331 comprises two vertical plates 3310 arranged on the support base plate 310, a transverse plate 3311 fixedly connected between the two vertical plates 3310, and a pressing plate 3312 screwed to the upper end surface of the transverse plate 3311, a pressing channel which vertically runs through the pressing plate 3312 and the transverse plate 3311 is formed in the pressing plate 3312, and the self-reset key pressing rod component 332 is arranged in the pressing channel in a penetrating manner. The pressing rod support 331 is equivalent to an inverted 'U' -shaped structure, and has a stable structure. The pressing lever support 331 is mainly used as the self-resetting key pressing lever 332 assembly vertically penetrating therethrough and capable of sliding up and down, so that the structure of the pressing lever support 331 can be adapted to meet the function, for example, the pressing lever support 311 is designed as a transverse block, the pressing channel is arranged in the transverse block, and the like.

As shown in fig. 3, the number of the pressing channels is greater than or equal to the number of the self-resetting key pressing rods 3320 included in the self-resetting key pressing rod assembly 332, and the internal structure of one pressing channel is described in detail as follows: the pressing channel comprises a first channel 3312A, a second channel 3311A and a third channel 3311B, which are sequentially arranged in the pressing plate 3312 from top to bottom, and a transverse plate 3311. The width of the first channel 3312A is equal to the width of the third channel 3311B, and the widths of the first channel 3312A and the third channel 3311B are both smaller than the width of the second channel 3311A. This is designed so that the self-resetting key lever assembly 332 can be captured between the first and third passages 3312A, 3311B, preventing the self-resetting key lever assembly 332 from disengaging from the pressing passages when it is moved downward.

The self-resetting key pressing rod assembly 332 comprises a plurality of self-resetting key pressing rods 3320 which correspond to the key buttons of the key 500 to be detected one by one. The self-resetting key pressing rod 3320 comprises a pressing rod body 3321 penetrating through the pressing channel and a self-resetting spring 3322, wherein a limit stop 3321A abutting against the bottom surface of the first channel 3312A is annularly arranged on the periphery of the pressing rod body 3321, the self-resetting spring 3322 is annularly arranged on the pressing rod body 3321, and the upper end and the lower end of the self-resetting spring 3322 respectively abut against the lower surface of the limit stop 3321A and the bottom surface of the second channel 3311A. With this design, the main body 3321 of the pressing rod can move in the pressing channel without falling off due to the limitation of the limit stop 3321A.

It will be appreciated that the pressing mechanism 330 is not limited to the cam assembly 333, and any mechanism that presses downward on an object can be used. Such as a lever-type press block, such as an electric, pneumatic, hydraulic mechanism that moves vertically, can effect the depression of the self-resetting key plunger 3320.

Specifically, the driving assembly 3332 includes two bearing seats 3332A disposed at two end sides of the supporting base plate 310, a rotating shaft 3332B installed between the two bearing seats 3332A and parallel to and above the self-resetting key pressing rod assembly 332, a second gear 3332C coaxially connected to one end of the rotating shaft 3332B, a first gear 3332D engaged with the second gear 3332C, and a driving motor 3332E driving the first gear 3332D to rotate, and the cam assembly 333 is annularly disposed on the rotating shaft 3332B to rotate with the rotating shaft 3332B. The driving motor 3332E can be a DC motor capable of working in high and low temperature environment, and has a driving current of 12V and a rotation speed of about 60 rpm. How many keys are on the key 500 to be detected, for example: when the durability test is performed, the rotating shaft 3332B is provided with a cam 3331 matched with the unlocking key, the locking piece, the vehicle searching key, the tail gate key and the like, and the self-reset key pressing rod 3320 is matched and pressed to press the key.

The driving motor 3332E is installed at one end side of the support base plate 310 through a motor support plate 400 having a through hole, the driving motor 3332E is installed at an outer side of the motor support plate 400 corresponding to the through hole, an output shaft of the driving motor 3332E passes through the through hole inward to be located at an inner side of the motor support plate 400, and the first gear 3332D is coaxially installed at the output shaft of the driving motor 3332E.
