Description

Technical Field

[0001] The utility model relates to the technical field of vehicle electronic control module testing, in particular to a testing device for vehicle electronic control modules. Background Technique

[0002] The vehicle electronic control module is an important device during the use of a vehicle. It not only controls the engine but also the safety system. When a vehicle system fails, it can give an early warning in a timely manner. In addition, the vehicle electronic control module also plays a role in power management and lighting control;

[0003] During the production of vehicle electronic control modules, various tests need to be carried out on them, such as basic function tests and compatibility tests. The strength test of the vehicle electronic control module itself is also a very important link;

[0004] During actual use, the PCB board may be subjected to forces of different magnitudes. Therefore, during testing, it is also necessary to flexibly adjust the magnitude of the test force. If the magnitude of the test force cannot be adjusted quickly, it will lead to a single and inaccurate test result;

[0005] In order to overcome the above defects, there is a PCB board strength testing device in the prior art 1 (a Chinese patent with the application number CN202020657392.X and the application date of April 27, 2020). It can adjust the bending range of the circuit board during testing, making it more flexible and convenient to use;

[0006] During the testing process, the PCB board may break directly. After the testing is completed, the broken PCB board needs to be collected by the staff. However, the device in the above application does not have the function of concentrating debris during use, which increases the workload of the staff in the later stage and reduces the work efficiency.

[0007] In view of the above problems, there is an urgent need to innovate and design on the basis of the original testing device for vehicle electronic control modules. Content of the Utility Model

[0008] The purpose of the utility model is to provide a testing device for vehicle electronic control modules to solve the problem proposed in the above background technique that during use, it does not have the function of concentrating debris, which increases the workload of the staff in the later stage and reduces the work efficiency.

[0009] To achieve the above purpose, the utility model provides the following technical solution: A testing device for vehicle electronic control modules, including a working plate and a disc. The lower surface of the working plate is fixedly connected with a bracket, and the upper surface of the working plate is bolted with a vertical plate. A motor is bolted to the surface of the vertical plate, and a connecting shaft is fixedly connected to the output end of the motor;

[0010] The disc is fixedly connected to the output end of the connecting shaft, and a guiding block is fixedly connected to the surface of the disc;

[0011] It further includes:

[0012] A fixing rod, the fixing rod is bolted to the surface of the vertical plate, and a column is slidably arranged inside the fixing rod;

[0013] A limiting column, the limiting column is fixedly connected to the lower surface of the working plate, a lapping block is sleeved on the surface of the limiting column, and a material collecting frame is fixedly connected to the end of the lapping block, and a material discharging port is formed on the surface of the working plate.

[0014] Preferably, a movable frame is sleeved on the surface of the guiding block, and the column is fixedly connected to the upper surface of the movable frame.

[0015] Preferably, the columns are symmetrically distributed about the center of the movable frame, and an extrusion rod is fixedly connected to the lower surface of the movable frame.

[0016] Preferably, the extrusion rod is of a conical structure.

[0017] Preferably, a push block is fixedly connected to the surface of the connecting shaft, and the front view of the push block is of a fan-shaped structure.

[0018] Preferably, the lapping blocks are symmetrically distributed about the center of the material collecting frame, and an auxiliary rod corresponding to the push block is fixedly connected to the upper surface of the inner lapping block.

[0019] Preferably, a bottom plate is fixedly connected to the lower surface of the limiting column, a connecting spring for elastic reset is fixedly connected to the upper surface of the bottom plate, and the other side of the connecting spring is fixedly connected to the lower surface of the lapping block.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows: The test device for the vehicle electronic control module adopts a novel structural design, and the specific content is as follows:

[0021] For the test device for the vehicle electronic control module, the workpiece to be detected is placed on the working plate to cover the material discharging port, and then the motor is started. The motor drives the connecting shaft and the disc to rotate. When the disc rotates, the movable frame and the extrusion rod are driven to descend through the guiding block, the column and the fixing rod, so as to achieve the purpose of the most basic strength detection;

[0022] Furthermore, the descending height of the extrusion rod can be adjusted with the rotation of the disc. Therefore, during use, the rotation angle of the disc can be reasonably controlled by the motor, so that the extrusion force is flexibly adjustable, the flexibility of the whole device is improved, and the accuracy of the detection result is further improved;

[0023] (2)The test device for the vehicle electronic control module. During the detection process, if the control module board breaks, the fractured workpiece will fall through the material receiving frame. The material receiving frame plays a role in restricting the landing point of the workpiece and will not scatter the debris, thus facilitating the collection work of subsequent staff.

[0024] Furthermore, after the workpiece breaks, the motor continues to work, and thus the connecting shaft is always in a rotating state. At this time, the connecting shaft will intermittently push the auxiliary rod through the push block. Then, under the action of the thrust, the latching block, and the connecting spring, the auxiliary rod makes a reciprocating linear motion in the vertical direction. At this time, the material receiving frame is in a vibrating state, which is convenient for the rapid discharge of the fragmented workpieces and will not cause the situation of residual debris inside the material receiving frame.

[0025] Even further, the latching block, the limit post, and the auxiliary rod ensure that the material receiving frame only moves in the vertical direction, guaranteeing stability. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] Embodiment 1: By setting the motor 3 and the extrusion rod 8, the purpose of strength detection is achieved. At the same time, the extrusion strength of the extrusion rod 8 can be adjusted, improving flexibility. As Figures 1 - 4 shown:

[0035] It includes a working plate 1 and a disc 5. A bracket is fixedly connected to the lower surface of the working plate 1, and a vertical plate 2 is bolted to the upper surface of the working plate 1. A motor 3 is bolted to the surface of the vertical plate 2, and a connecting shaft 4 is fixedly connected to the output end of the motor 3. The disc 5 is fixedly connected to the output end of the connecting shaft 4, and a guide block 6 is fixedly connected to the surface of the disc 5;

[0036] It also includes:

[0037] A fixed rod 10, the fixed rod 10 is bolted to the surface of the vertical plate 2, and a column 9 is slidably arranged inside the fixed rod 10. A limit column 15, the limit column 15 is fixedly connected to the lower surface of the working plate 1, and a lap joint block 14 is sleeved and connected to the surface of the limit column 15. The end of the lap joint block 14 is fixedly connected to a material receiving frame 13, and a material discharge port 11 is opened on the surface of the working plate 1.

[0038] A movable frame 7 is sleeved and connected to the surface of the guide block 6, and a column 9 is fixedly connected to the upper surface of the movable frame 7. The columns 9 are symmetrically distributed about the center of the movable frame 7, and an extrusion rod 8 is fixedly connected to the lower surface of the movable frame 7. The extrusion rod 8 is of a conical structure.

[0039] During operation, the workpiece to be detected is placed on the working plate 1 to cover the material discharge port 11. Then, the motor 3 on the surface of the vertical plate 2 is started. The motor 3 drives the connecting shaft 4 and the disc 5 to rotate. When the disc 5 rotates, the movable frame 7 and the extrusion rod 8 are driven to descend through the guide block 6, the column 9 and the fixed rod 10, achieving the purpose of basic strength detection. The descending height of the extrusion rod 8 can be adjusted with the rotation of the disc 5. Therefore, during use, by reasonably controlling the rotation angle of the disc 5 by the motor 3, the extrusion force can be flexibly adjusted, improving the overall flexibility of the device and thus the accuracy of the detection result.

[0040] Embodiment 2: Different from Embodiment 1, by setting the material receiving frame 13, the position where the debris of the control module falls can be restricted, facilitating collection by the staff. As Figure 5 shown:

[0041] A push block 12 is fixedly connected to the surface of the connecting shaft 4, and the front view of the push block 12 is a sector structure.

[0042] The lapping blocks 14 are symmetrically distributed about the center of the material receiving frame 13, and an auxiliary rod 18 corresponding to the push block 12 is fixedly connected to the upper surface of the inner lapping block 14.

[0043] During the detection process, if the control module board breaks, the broken workpieces will fall through the blanking port 11 and the material receiving frame 13. At this time, the material receiving frame 13 plays a role in restricting the landing points of the workpiece debris, preventing the debris from scattering, and thus facilitating the collection work of the subsequent staff.

[0044] Embodiment 3: Different from Embodiment 2, by arranging the connecting spring 17, the material receiving frame 13 moves in the vertical direction, thereby enabling better discharging, as Figure 5 and Figure 6 shown:

[0045] The lower surface of the limit post 15 is fixedly connected to a bottom plate 16, and a connecting spring 17 that plays an elastic reset role is fixedly connected to the upper surface of the bottom plate 16, and the other side of the connecting spring 17 is fixedly connected to the lower surface of the lapping block 14.

[0046] After the workpiece breaks, the motor 3 continues to operate, so that the connecting shaft 4 is always in a rotating state. At this time, the connecting shaft 4 intermittently pushes the auxiliary rod 18 through the push block 12. When the push block 12 pushes the auxiliary rod 18, the auxiliary rod 18, the lapping block 14, and the material receiving frame 13 descend. At this time, the lapping block 14 and the bottom plate 16 cooperate to squeeze the connecting spring 17. When the push block 12 continues to rotate to stop pushing the auxiliary rod 18, the lapping block 14 and the material receiving frame 13 rise under the action of the connecting spring 17. Repeating the above process, the material receiving frame 13 makes a reciprocating linear motion in the vertical direction. At this time, the material receiving frame 13 is in a vibrating state, facilitating the rapid discharge of the broken workpieces and preventing the situation of residual debris inside the material receiving frame 13.

[0047] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0048] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
