Detailed Implementation

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1-3 As shown, a testing device for hydrogen fuel cell production includes a housing 1, on which a pair of movable seats 2 are mounted. A swing block 3 is rotatably mounted on one side of each movable seat 2. The swing block 3 is equipped with a clamping block 4 for clamping the battery and an adjustment mechanism for driving the clamping block 4 to move closer or further apart. The movable seat 2 is also equipped with a flipping detection mechanism 5 for flipping the clamping block 4. The flipping detection mechanism 5 includes a positioning rod 51, a main gear 52, and a drive mechanism 6 for driving the main gear 52 to rotate. The positioning rod 51 rotates on the movable seat 2 and is fixedly connected to the swing block 3. The main gear 52 is fixedly mounted on the positioning rod 51. The housing 1 is also equipped with a reciprocating impact mechanism 7 for impact testing of the bottom of the clamped battery.

[0027] When the battery needs to be clamped, the adjustment mechanism is first activated, which drives a pair of moving seats 2 to move closer together and drives a pair of clamping blocks 4 to clamp and fix the battery placed on the housing 1 until the battery is clamped by the clamping blocks 4. Then, by setting a reciprocating impact mechanism 7, the clamped battery can be subjected to a reciprocating impact test on the bottom to test the battery's impact resistance. After the impact, by setting a flipping detection mechanism 5, the bottom side of the battery that was impacted can be flipped over, making it easy to observe and record the bottom of the battery after the test.

[0028] See Figures 4-6As shown, the flipping detection mechanism 5 also includes a connecting block 53, a guide post 54, and a stroke groove 55; the connecting block 53 is disposed on the swing block 3; the guide post 54 is disposed on the connecting block 53; the stroke groove 55 is opened on the movable seat 2, and the guide post 54 is located in the stroke groove 55 and slides. The housing 1 is provided with a control display 11 and a camera detection sensor 12. The camera detection sensor 12 is used to detect the degree of damage to the surface of the battery after it is impacted, and sends the shooting and detection results to the control display 11. The control display 11 is used to display the degree of damage to the battery after it is impacted.

[0029] During the process of flipping the clamped battery after impact, the swing block 3 can swing stably due to the restriction of the guide post 54 on the connecting block 53 and the stroke groove 55 on the moving seat 2. This enhances the stability of the swing block 3 during tilting and swinging. After flipping, the camera detection sensor 12 can detect the degree of impact damage to the bottom of the battery and take pictures. The shooting and detection results can be displayed and saved on the control display 11 in real time.

[0030] See Figure 4 and Figure 5 As shown, the drive mechanism 6 includes a first rotary driver 61, a transmission rod 62, and a driven gear 63; the first rotary driver 61 is mounted on the movable seat 2 and located above the swing block 3; the transmission rod 62 is connected to the output end of the first rotary driver 61 via a coupling, and the transmission rod 62 is located above the positioning rod 51; the driven gear 63 is mounted on the transmission rod 62 and is coaxially fixed with the transmission rod 62, and the driven gear 63 meshes with the main gear 52.

[0031] When the swing block 3 needs to be swung, the first rotary driver 61 is activated, which in turn drives the transmission rod 62 to rotate. When the transmission rod 62 rotates, it drives the driven gear 63, which is fixed to the same axis. The driven gear 63 drives the main gear 52, which meshes with it, to rotate. Since the main gear 52 is fixed to the same axis as the positioning rod 51, when the main gear 52 rotates, it can drive the positioning rod 51 and the swing block 3 to swing at an angle, thereby achieving automatic flipping of the clamped battery, so as to facilitate the observation and recording of the impact damage area on the bottom of the battery.

[0032] See Figures 3-7 As shown, the reciprocating impact mechanism 7 includes a mounting plate 71, an impact column 72, and an impact head 73; the impact column 72 is disposed on the mounting plate 71 and has several of them, the impact column 72 is vertically slidably disposed on the housing 1, the impact head 73 is disposed on the impact column 72, and the reciprocating impact mechanism 7 also includes a second rotary driver 76 that drives the mounting plate 71 to reciprocate.

[0033] When an impact test is required on the bottom of the battery, the mounting plate 71 can slide vertically and stably along the housing 1 until the impact head 73 on the impact column 72 contacts the bottom of the clamped battery and performs an impact test on the bottom of the clamped battery, thereby achieving the goal of performing an impact test on the bottom of the battery.

[0034] See Figure 3 As shown, the reciprocating impact mechanism 7 also includes a damping spring 74 and a buffer plate 75; the damping spring 74 is mounted on the housing 1, and the two ends of the damping spring 74 are fixed to the mounting plate 71 and the end of the housing 1, respectively; the buffer plate 75 is mounted on the housing 1.

[0035] When the mounting plate 71 rises vertically, the damping spring 74 is compressed until the mounting plate 71 contacts the buffer plate 75 on the housing 1, at which point the upward movement of the mounting plate 71 stops. When the mounting plate 71 slides vertically upward, the buffer plate 75 reduces the hard contact between the mounting plate 71 and the housing 1, thereby improving the service life of the mounting plate 71 and the buffer plate 75, and can also reduce the noise generated by the mounting plate 71 during reciprocating movement to a certain extent.

[0036] See Figure 7 As shown, the reciprocating impact mechanism 7 also includes a second rotary driver 76 and a rotary contact block 77; the second rotary driver 76 is disposed on the housing 1 and located below the mounting plate 71; the rotary contact block 77 is disposed at the output end of the second rotary driver 76, and the convex surface of the rotary contact block 77 is used to contact the bottom surface of the mounting plate 71 to drive the mounting plate 71 to move up and down.

[0037] When the mounting plate 71 needs to be moved vertically up and down, the second rotary driver 76 is activated first, which drives the rotary contact block 77 to rotate. When the rotary contact block 77 rotates, it can reciprocate to lift the mounting plate 71, thereby achieving reciprocating vertical lifting and sliding of the mounting plate 71.

[0038] See Figure 7As shown, the adjustment mechanism includes a second bidirectional screw 44, a second linear actuator 45, and a support frame 46. The support frame 46 is located on one side of the swing block 3. A first bidirectional screw 42 is installed inside the support frame 46. A first linear actuator 41 is installed on one side of the support frame 46. The output end of the first linear actuator 41 is connected to the first bidirectional screw 42. The first bidirectional screw 42 is threadedly connected to the clamping block 4. A limiting block 43 is installed on one side of the swing block 3 to improve the stability of the movement of the clamping block 4. A sliding groove is provided on the housing 1 for the moving seat 2 to move. A second bidirectional screw 44 is installed in the sliding groove. A second linear actuator 45 is installed on one side of the housing 1. The output end of the second linear actuator 45 is connected to the second bidirectional screw 44. The second bidirectional screw 44 is threadedly connected to the moving seat 2.

[0039] When it is necessary to clamp the battery, the second linear actuator 45 is activated, which drives the second bidirectional screw 44 to rotate. The rotation of the second bidirectional screw 44 causes a pair of moving seats 2 to move closer to each other. The first linear actuator 41 is activated, which drives the first bidirectional screw 42 to rotate. The first bidirectional screw 42 causes a pair of clamping blocks 4 to gradually contact the battery until the battery is clamped and fixed.

[0040] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
