[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] A seat lock unlocking force testing device, such as Figure 1-Figure 3 As shown, the system comprises a frame 1, a traversing assembly 2, a lifting assembly 3, and an angle acquisition assembly 4, a torque sensor 5, a positioning assembly 6, an unlocking arm 7, and an actuator 8, mounted on the lifting assembly 3. The traversing assembly 2 is mounted on the frame 1, and the lifting assembly 3 is mounted on the traversing assembly 2. The actuator 8 is connected to the unlocking arm 7 via the angle acquisition assembly 4, the torque sensor 5, and the positioning assembly 6. The actuator 8 provides driving force to the unlocking arm 7, which acts on the seat lock to unlock the seat lock. The angle acquisition assembly 4 acquires the rotation angle of the unlocking arm 7, and the torque sensor 5 acquires the torque currently applied to the unlocking arm 7. The unlocking position of the seat lock is also identified by the positioning assembly 6; that is, the unlocking position of the seat lock is determined according to the product design. The positioning assembly 6 identifies whether the current position is the unlocking position. When the positioning assembly 6 identifies the unlocking position, the current torque value is recorded.

[0021] In one embodiment, if Figure 1-Figure 3 As shown, the actuator 8, angle acquisition assembly 4, torque sensor 5, positioning assembly 6, and unlocking arm 7 are sequentially connected via a coupling. This configuration represents the optimal connection method; however, the angle acquisition assembly 4, torque sensor 5, and positioning assembly 6 are not limited to the above connection order and can be changed based on actual needs.

[0022] In one embodiment, if Figure 1-Figure 3 As shown, the traverse assembly 2 includes a first movable plate 21, a slide cylinder 22, and a first guide rail 23. The slide cylinder 22 and the first guide rail 23 are horizontally arranged on the frame 1, and the first movable plate 21 is mounted on the slide cylinder 22 and the first guide rail 23. The slide cylinder 22 provides power to the first movable plate 21, while the first guide rail 23 bears part of the load on the first movable plate 21, thereby extending the service life of the traverse assembly 2.

[0023] In one embodiment, if Figure 1-Figure 3 As shown, the lifting assembly 3 includes a lifting plate 31, a second guide rail 32 and a cylinder 33. The second guide rail 32 is vertically arranged, and the lifting plate 31 is arranged on the second guide rail 32. The cylinder 33 is used to drive the lifting plate 31 to move vertically along the second guide rail 32. Among them, two second guide rails 32 are arranged in parallel.

[0024] In one embodiment, if Figure 1-Figure 3 As shown, the angle acquisition component 4 includes an encoder 41, a belt 42 and a pulley 43. The pulley 43 connects the actuator 8 and the torque sensor 5. The encoder 41 is set on the lifting component 3. The belt 42 connects the encoder 41 and the pulley 43. The encoder 41 is used to collect angle signals.

[0025] In one embodiment, if Figure 1-Figure 3As shown, positioning assembly 6 comprises a fixed bracket 61, a disk 62, and a sensor 63. Sensor 63 is mounted on lifting assembly 3 via fixed bracket 61. Disk 62 is connected to actuator 8 and is provided with a sensing portion, which sensor 63 identifies. In this embodiment, the disk is connected to torque sensor 5 and unlocking arm 7. Actuator 8 synchronously drives disk 62 to rotate, thereby causing the sensing portion to move in a circular motion. When sensor 63 identifies the sensing portion, it indicates that the current position is the set unlocking position.

[0026] In the above embodiment, if Figure 1-Figure 3 As shown, the sensing portion is a through hole, and the sensor 63 is a photoelectric sensor. When the through hole corresponds to the photoelectric sensor, the light beam of the photoelectric sensor passes through the through hole and is received, and the sensor 63 is open at this time, otherwise it is closed.

[0027] In the above embodiment, if Figure 1-Figure 3 As shown, three sensors 63 are provided. One of them is used to sense the unlocking position, and the remaining two are used for rotation limiting, that is, limiting the rotation range of the unlocking arm.

[0028] In one embodiment, if Figure 1-Figure 3 As shown, the actuator 8 is a servo motor.

[0029] When the utility model is in use, Figure 1-Figure 3 As shown, in order to improve the detection efficiency, two workstations are usually set up, and the unlocking arm 7 is controlled to move between the two workstations by the horizontal component 2. When one workstation is detecting, the other workstation is loading and unloading; during detection, the lifting plate 31 is driven downward by the cylinder 33 of the lifting component 3, so that the unlocking arm 7 moves downward, and the actuator 8 starts to drive the unlocking arm 7 to move. At the same time, the angle acquisition component 4, the torque sensor 5 and the sensor 63 of the positioning component 6 all start working. When the torque sensor 5 collects data, it means that the torque arm 7 is in contact with the seat lock, and it continues to run and collect data. The relationship table between the position of the unlocking arm 7 and the torque value can be observed. At the same time, the torque value is marked at the set unlocking position, which can clearly detect the force required in the unlocking process of the seat lock, thereby avoiding false detection and wrong detection.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
