Technical Field
[0001] This utility model relates to a testing device, and more particularly to a positioning device for testing, mainly used for testing automotive seat drive motors. Background Technology
[0002] Car seats provide drivers and passengers with a convenient, comfortable, and safe driving and riding position. There are two main types of car seats: manual and electric. Electric adjustable car seats primarily use actuators to move the seat or rotate the backrest angle.
[0003] The motor is the main power component in the drive. After the motor is manufactured, it needs to undergo aging tests to test its performance and reliability. In existing technology, the motor is typically limited by elbow clamps on the aging rack, and two clamps are set next to each elbow clamp for connecting to the motor's wiring to supply power.
[0004] This structure has the following shortcomings:
[0005] 1. Because the aging rack has a large number of test positions, each test position requires an elbow clamp, which makes the cost relatively high;
[0006] 2. Although elbow clamps are relatively simple to operate, in actual operation, especially when using a shackle, there may be situations where they are not unlocked or require multiple unlocking attempts, which affects the convenience of operation. Summary of the Invention
[0007] The purpose of this invention is to provide a positioning device for testing, which improves positioning efficiency and convenience while reducing costs.

[0009] The connector includes a support plate, a positioning plate, a vertical rod, and a spring. The support plate is installed on the positioning block on the right side of the positioning groove. The bottom of the vertical rod is vertically installed on the top of the support plate. The positioning plate is installed on the vertical rod. The right end of the pressure plate is rotatably connected to the vertical rod. The spring is sleeved on the vertical rod. The top of the spring abuts against the bottom surface of the positioning plate, and the bottom of the spring abuts against the top surface of the pressure plate.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0029] Example 1: See Figure 1-6 As shown, a positioning device for testing includes a base plate 1, a positioning block 2 mounted on the base plate, a pressure plate 3, and a wiring part 4. The top of the positioning block 2 is provided with a positioning groove 5. The pressure plate 3 is mounted on the positioning block 2 via a connector. The wiring part 4 is located on the side of the positioning block 2.
[0030] The connector includes a support plate 6, a positioning plate 7, a vertical rod 8, and a spring 9. The support plate 6 is installed on the positioning block 2 on the right side of the positioning groove 5. The bottom of the vertical rod 8 is vertically installed on the top 6 of the support plate. The positioning plate 7 is installed on the vertical rod 8. The right end of the pressure plate 3 is rotatably connected to the vertical rod 8. The spring 9 is sleeved on the vertical rod 8. The top of the spring 9 abuts against the bottom surface of the positioning plate 7, and the bottom of the spring 9 abuts against the top surface of the pressure plate 3. The left end of the pressure plate 3 rotates directly above the positioning groove 5 or rotates in front of the support plate 6.
[0031] In this embodiment, when positioning the product, the bottom of the product (motor) is directly placed into the positioning slot. At this time, the left end of the pressure plate is on the support plate and on the right side of the positioning slot, which does not affect the product's placement into the positioning slot. Then, the pressure plate is rotated so that the left end of the pressure plate rotates to the top of the positioning slot and quickly presses down on the top surface of the product. During this process, due to the presence of the spring, the pressure plate moves upward and applies downward pressure through the spring force, pressing the pressure plate against the top of the product and preventing the product from detaching from the positioning slot. Then, the two wires on the product are connected to the wiring part, and the product is powered on for testing through the wiring part. After the test is completed, the pressure plate is rotated in the opposite direction so that the left end of the pressure plate rotates to the support plate, disconnecting the wiring part from the product's wires. Then, the product can be removed from the positioning slot. This method is convenient, quick, simple in structure, and low in cost.
[0032] In this embodiment, the base plate is provided with at least one set of positioning blocks, pressure plates and wiring parts, and multiple sets can be provided so that multiple products can be tested at the same time.
[0033] In this embodiment, the top of the upright has an external thread, on which two nuts 10 are screwed. A positioning plate is fitted onto the upright and positioned between the two nuts. The bottom surface of one nut abuts against the top surface of the positioning plate, and the top surface of the other nut abuts against the bottom surface of the positioning plate. This design facilitates the disassembly of the positioning plate, pressure plate, and spring, and makes it easy to maintain and replace the spring and pressure plate. It is particularly convenient for the maintenance and replacement of the spring (after prolonged use, the elastic deformation capacity of the spring tends to weaken; therefore, it can be quickly replaced once its elastic deformation capacity weakens, resulting in low maintenance and replacement costs). Furthermore, by adjusting the height of the two nuts relative to the upright, the pressure of the spring on the pressure plate can be adjusted, and the service life of the spring can be extended after its restoring force weakens.
[0034] See Figure 1-4 As shown, the upright 8 is installed on the rear side of the top surface of the support plate 6, the length of the positioning plate 7 is less than the length of the support plate 6, and there is a longitudinal gap between the front end face of the positioning plate 7 and the front end face of the support plate 6.
[0035] In this embodiment, when the left end of the pressure plate is rotated to the top of the support plate, the left end of the pressure plate will be in front of the positioning plate, so that the left end of the pressure plate is unobstructed and does not affect the operator's ability to grasp the pressure plate and rotate it to the top of the positioning groove to limit the product.
[0036] See Figure 2 , 3 As shown, the rear side of the pressure plate 3 is an inclined surface 11, with the right rear side of the inclined surface 11 tilted downwards. In this embodiment, when the left end of the pressure plate rotates onto the support plate, the bottom surface of the pressure plate abuts against the top surface of the support plate. After the product is placed into the positioning slot, the top plane of the product to be positioned is above the top plane of the support plate, but below the top plane of the pressure plate. Therefore, to facilitate the operator's rotation of the pressure plate to limit the product, when the operator grasps the left end of the pressure plate and rotates it clockwise, the inclined surface will first contact the top surface of the product. Due to the rotational force of the pressure plate, the product will squeeze the inclined surface of the pressure plate and push the pressure plate to gradually move upwards until the bottom surface of the product abuts against the top surface of the product. After that, the pressure plate will not continue to move upwards until the pressure plate rotates to the corresponding position. During the upward movement of the pressure plate, the right end of the pressure plate moves upwards along the upright and compresses the spring. The restoring force of the spring will give the pressure plate downward pressure, so that the pressure plate is stably pressed against the top surface of the product.
[0037] See Figure 1-4 As shown, a gripper 12 is provided on the top left side of the pressure plate 3. The gripper allows the operator to rotate the pressure plate by grasping it, thereby limiting or releasing the product.
[0038] See Figure 5 , 6 As shown, the wiring part 4 includes a base block 41 and two wire pressing plates 42 disposed on the base block 41. Two conductive pieces 43 are provided on the top surface of the base block 41. Each conductive piece 43 is connected to the controller via a cable. The right end of each wire pressing plate 42 is disposed above a conductive piece 43.
[0039] The top surface of the bottom block 41 is provided with three spaced vertical plates 44, and a wiring port 45 is formed between adjacent vertical plates 44. Each conductive sheet 43 is disposed on the bottom surface of a wiring port 45, and the right side wall of the conductive sheet 43 is flush with the right side wall of the wiring port 45.
[0040] Each of the wire pressing plates 42 has its right end disposed within a terminal 45. The middle part of the wire pressing plate 42 is rotatably connected to the upright plates 44 on both sides of the terminal 45. A push spring 46 is provided on the top surface of the bottom block 41 on the left side of each conductive sheet 43. Each push spring 46 is disposed below a wire pressing plate 42. The bottom of the push spring 46 is connected to the top of the bottom block 41, and the top of the push spring 46 is connected to the bottom surface of the corresponding upper wire pressing plate 42. The push spring 46 pushes the left side of the wire pressing plate 42 to move upward, and causes the bottom surface of the right end of the wire pressing plate 42 to abut against the top surface of the corresponding conductive sheet 43.
[0041] In this embodiment, the base, pressure plates, and upright plates are all made of insulating material and are non-conductive. The controller energizes the conductive plates via cables. During use, the ends of the two wires are exposed and conductive. The operator presses the left ends of the two pressure plates, causing the right ends to lift away from the corresponding conductive plates and compressing the push springs. Then, the ends of the two wires are placed into a connection port between the conductive plate and the pressure plate. Releasing the pressure plates causes the restoring force of the push springs to lift the left end of the pressure plate and lower the right end, pressing the corresponding wire onto the conductive plate, thus establishing an electrical connection between the conductive plate and the product's wires. After the controller energizes the conductive plates, the product can be tested. The upright plates provide two independent connection ports, preventing short circuits caused by the two wires touching and ensuring testing accuracy. During disassembly, the operator simply grasps the two wires on the product and applies a certain pulling force to pull them out from between the pressure plates and the conductive plates. Of course, if the product size is small and the wires are relatively thin, to prevent the wires from breaking, the operator can press down the left end of the clamping plate and lift the right end to quickly remove the wires. Compared with the existing technology that uses clamps for power connection, the wire clamping efficiency is higher and more convenient.
[0042] See Figure 5 , 6 As shown, the middle part of the pressure plate 42 is rotatably connected to the left ends of the two adjacent upright plates 44 via a pivot 47. The push spring 46 is located on the outside of the left side of the wiring port 45, and is also located on the left side of the pivot 47. In this configuration, the left ends of both pressure plates are located on the outside of the left side of the upright plates. When the operator presses the left end of the pressure plate, both pressure plates can be pressed simultaneously, making pressing more convenient and eliminating the need for individual pressing.
