An adjustment assembly 2 is provided at the top of the bottom plate 1. Fixing frames 3 that cooperate with the bottom plate 1 are provided on both sides of the adjustment assembly 2. A control panel 4 is provided on one side of the fixing frame 3. A detection member 5 that cooperates with the adjustment assembly 2 is provided at the middle position of the fixing frame 3. A driving assembly 6 that cooperates with the fixing frame 3 is provided on one side of the detection member 5.

[0026] With the aid of the above technical solution, the present utility model realizes the detection operation of the automotive electronic controller under the action of the driving assembly 6 and the detection member 5, verifies the production quality of the automotive electronic controller, and at the same time can accurately test the key performance parameters of the automotive electronic controller to ensure that each product meets the quality standards set by the manufacturer, improving the reliability of producing automotive electronic controllers; under the action of the adjustment assembly 2, without manual operation, the automotive electronic controller at the top of the adjustment assembly 2 can be adjusted to the same centered position, ensuring the accuracy of each detection operation, avoiding the collision between the detection member 5 and the automotive electronic controller, and improving the quality and efficiency of the detection operation.

[0027] In one embodiment, for the above-mentioned adjusting component 2, the adjusting component 2 includes a support column 201 arranged at the top end of the bottom plate 1. The top end of the support column 201 is provided with a support plate 202. The outer side of the support plate 202 is provided with a square outer shell 203 that cooperates with the bottom plate 1. The top end of the support plate 202 is evenly provided with limiting grooves 204 around the perimeter. Inside the two groups of transverse limiting grooves 204, there are sliders 205 provided. Inside the two groups of longitudinal limiting grooves 204, there are sliders 206 provided. The bottom ends of the two groups of sliders 205 and the two groups of sliders 206 are all provided with connecting rods 207. The other ends of several connecting rods 207 are provided with limiting plates 208 that cooperate with the support column 201. The two sides of the bottom ends of the two groups of sliders 206 are connected by symmetrically arranged electric push rods 209. The top ends of the two groups of sliders 206 and the two groups of sliders 205 are all provided with baffles. The shape of the limiting groove 204 is a concave shape. The shapes of the two groups of sliders 205 and the two groups of sliders 206 are both H-shaped. Thus, it is ensured that the automotive electronic controller can maintain the same position in the center during the detection process.

[0028] The working principle of the adjusting component 2 is as follows: When it is necessary to adjust the automotive electronic controller, through the control panel 4, the electric push rod 209 in the adjusting component 2 is controlled and started. Under the shortening action of the output shaft of the electric push rod 209, the two groups of sliders 206 are driven to approach each other along the limiting grooves 204. Under the approaching action of the two groups of sliders 206, the connecting rods 207 at the bottom ends of the two groups of sliders 206 are driven to rotate clockwise. Under the clockwise rotation action of the connecting rods 207, the limiting plate 208 is driven to rotate clockwise along the support column 201. Under the rotation action of the limiting plate 208, the connecting rods 207 at the bottom ends of the two groups of sliders 205 are driven to rotate clockwise. Under the rotation action of the connecting rods 207, the two groups of sliders 205 are driven to approach each other along the limiting grooves 204. Under the approaching action of the two groups of sliders 206 and the approaching action of the two groups of sliders 205, the automotive electronic controller is contacted through the baffles 210 at the top ends of the two groups of sliders 206 and the two groups of sliders 205, realizing the adjustment of the automotive electronic controller at the top end of the support plate 202 and ensuring that the automotive electronic controller is always in the same central position.

[0029] After the automotive electronic controller performs the detection operation, through the control panel 4, the electric push rod 209 in the adjustment component 2 is controlled and started. Under the elongation action of the output shaft of the electric push rod 209, two groups of second sliders 206 are driven to move away from each other along the limit groove 204. Under the action of the separation of the two groups of second sliders 206, the connecting rod 207 at the bottom of the two groups of second sliders 206 is driven to rotate counterclockwise. Under the counterclockwise rotation action of the connecting rod 207, the limit plate 208 is driven to rotate counterclockwise along the support column 201. Under the rotation action of the limit plate 208, the connecting rod 207 at the bottom of the two groups of first sliders 205 is driven to rotate counterclockwise. Under the rotation action of the connecting rod 207, the two groups of first sliders 205 are driven to move away from each other along the limit groove 204. Under the action of the separation of the two groups of second sliders 206 and the two groups of first sliders 205, the baffle plates 210 at the tops of the two groups of second sliders 206 and the two groups of first sliders 205 are separated from the automotive electronic controller, so that the automotive electronic controller can be replaced.

[0030] In one embodiment, for the above-mentioned detection piece 5, the detection piece 5 includes a movable rod 501 arranged at the middle position of the fixed frame 3. A pressing plate 502 is arranged at the bottom end of the movable rod 501. A first spring 503 is arranged at the bottom end of the pressing plate 502. A limit ring 504 that cooperates with the adjustment component 2 is arranged at the bottom end of the first spring 503. A detection interface 505 that cooperates with the pressing plate 502 is arranged inside the limit ring 504; thus, the detection effect on the automotive electronic controller is ensured.

[0031] It should be explained that the detection interface 505 internally has detection probes that cooperate with the automotive electronic controller. During the test of the automotive electronic controller, the detection probes directly contact the interface position in the automotive electronic controller to collect key signals and data, realizing the detection operation of the automotive electronic controller. This is the prior art and will not be explained in detail here.

[0032] In one embodiment, for the above-mentioned driving component 6, the driving component 6 includes a fixed seat 601 sleeved on the outer circumference of the movable rod 501. A second spring 602 that cooperates with the fixed frame 3 is arranged at the bottom end of the fixed seat 601. A rotating plate 603 is arranged on one side of the fixed seat 601. A first connecting frame 604 that cooperates with the fixed frame 3 is arranged at the other end of the rotating plate 603. A second connecting frame 605 is arranged at the other end of the first connecting frame 604. A third connecting frame 606 that cooperates with the fixed frame 3 is arranged at the other end of the second connecting frame 605. A handle 607 is arranged at the top end of the third connecting frame 606; the shape of the rotating plate 603 is an arc shape; thus, the detection piece 5 and the automotive electronic controller can be in close contact.

[0033] The working principles of the detection component 5 and the driving component 6 are as follows: When it is necessary to detect the automotive electronic controller at the top of the adjustment component 2, hold the handle 607 in the driving component 6 by hand and rotate the handle 607 along the position where the third connecting frame 606 is connected to the fixed frame 3. Under the rotation of the handle 607, drive the third connecting frame 606 to rotate along the position connected to the fixed frame 3. Under the rotation of the third connecting frame 606, drive the second connecting frame 605 to rotate. Under the rotation of the second connecting frame 605, drive the first connecting frame 604 to rotate along the position connected to the fixed frame 3. Under the rotation of the first connecting frame 604, drive the rotating plate 603 to rotate. Under the rotation of the rotating plate 603, drive the fixed seat 601 to descend vertically. Under the descent of the fixed seat 601, compress the second spring 602, and at the same time drive the movable rod 501 to descend vertically. Under the descent of the movable rod 501, make the limiting ring 504 contact the automotive electronic controller at the top of the adjustment component 2, then compress the first spring 503, and at the same time make the detection interface 505 contact the interface of the automotive electronic controller, realizing the detection operation of the automotive electronic controller;

[0034] After the detection operation of the automotive electronic controller is completed, slowly release the handle 607. Under the reset action of the first spring 503, make the limiting ring 504 press against the automotive electronic controller, drive the pressing plate 502 away from the automotive electronic controller, separate the detection interface 505 from the interface of the automotive electronic controller, and at the same time reduce the friction between the adjustment component 2 and the automotive electronic controller during this process. At the same time, under the reset action of the second spring 602, drive the fixed seat 601 to rise vertically. Under the rise of the fixed seat 601, drive the movable rod 501 to rise vertically and drive the rotating plate 603 to rotate. Under the rotation of the rotating plate 603, drive the first connecting frame 604 to rotate along the position connected to the fixed frame 3. Under the rotation of the first connecting frame 604, drive the second connecting frame 605 to rotate. Under the rotation of the second connecting frame 605, drive the third connecting frame 606 to rotate along the position connected to the fixed frame 3. Under the rotation of the third connecting frame 606, drive the handle 607 to move to the starting position.

[0035] To facilitate the understanding of the above technical solutions of the present invention, the working principles or operation methods of the present invention in the actual process will be described in detail below.

[0036] In actual application, place the automotive electronic controller to be detected on the support plate 202 in the adjustment component 2, and then through the control panel 4, control and start the electric push rod 209 in the adjustment component 2. Under the shortening action of the output shaft of the electric push rod 209, the baffles 210 at the tops of the two groups of second sliders 206 and the two groups of first sliders 205 are in contact with the automotive electronic controller, realizing the adjustment of the automotive electronic controller at the top of the support plate 202 and ensuring that the automotive electronic controller is always in the same centered position;

[0037] Then, manually hold the handle 607 in the driving component 6 and rotate the handle 607 along the position where the connecting frame three 606 is connected to the fixing frame 3. Under the rotation action of the handle 607, the detection interface 505 in the detection component 5 is in contact with the interface of the automotive electronic controller, realizing the detection operation of the automotive electronic controller;

[0038] When the detection operation of the automotive electronic controller is completed, slowly release the handle 607 in the driving component 6. Under the reset action of the first spring 503 in the detection component 5, the limiting ring 504 abuts against the automotive electronic controller, driving the pressing plate 502 away from the automotive electronic controller, separating the detection interface 505 from the interface of the automotive electronic controller. At the same time, the friction between the adjustment component 2 and the automotive electronic controller during this process is reduced. At the same time, under the reset action of the second spring 602, the fixed seat 601 is driven to rise vertically. Under the rising action of the fixed seat 601, the movable rod 501 is driven to rise vertically, and the rotating plate 603 is driven to rotate. Under the rotation action of the rotating plate 603, the connecting frame one 604 is driven to rotate along the position where it is connected to the fixing frame 3. Under the rotation action of the connecting frame one 604, the connecting frame two 605 is driven to rotate. Under the rotation action of the connecting frame two 605, the connecting frame three 606 is driven to rotate along the position where it is connected to the fixing frame 3. Under the rotation action of the connecting frame three 606, the handle 607 is driven to move to the starting position;

[0039] After the detection operation of the automotive electronic controller, through the control panel 4, control and start the electric push rod 209 in the adjustment component 2. Under the elongation action of the output shaft of the electric push rod 209, the baffles 210 at the tops of the two groups of second sliders 206 and the two groups of first sliders 205 are separated from the automotive electronic controller, so that the automotive electronic controller can be replaced.

[0040] The working principles of the adjustment component 2, the detection component 5 and the driving component 6 are as shown above.

[0041] In summary, by means of the above technical solutions of the present utility model, under the action of the driving component 6 and the detecting component 5, the present utility model realizes the detection operation of the automotive electronic controller, verifies the production quality of the automotive electronic controller, and at the same time can accurately test the key performance parameters of the automotive electronic controller to ensure that each product meets the quality standards set by the manufacturer, improving the reliability of the production of automotive electronic controllers; under the action of the adjusting component 2, the automotive electronic controller at the top of the adjusting component 2 can be adjusted to the same centered position without manual operation, ensuring the accuracy of each detection operation, avoiding the collision between the detecting component 5 and the automotive electronic controller, and improving the quality and efficiency of the detection operation.
