DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0040] like Figures 1 to 15 As shown, the lead-acid battery testing equipment of the present invention includes a lead-acid battery 1, a support platform 2, a housing 3, a drive mechanism 4, and a test assembly 5. Driven by the drive mechanism 4, the test assembly 5 extends toward the first electrode 6 and the second electrode 7 of the lead-acid battery 1, maintaining contact with the test piece 8 to achieve electrical connection. In addition, a scanner 9 scans the QR code on the lead-acid battery 1 to ensure that the test information can be synchronized with the corresponding lead-acid battery 1 information. The motor 10 can drive the rotating plate 11 to rotate, thereby testing the lead-acid battery 1 in different positions.

[0041] The lead-acid battery 1 has a first electrode 6 and a second electrode 7. A first fixing plate 12, a second fixing plate 13, and a third fixing plate 14 are provided on the support platform 2. The lead-acid battery 1 is positioned between the first, second, and third fixing plates 12, 13, 14. The first fixing plate 12 is positioned opposite the second fixing plate 13, and the third fixing plate 14 is positioned perpendicular to the first and second fixing plates 12, 13.

[0042] The support platform 2 is used to support the lead-acid battery 1 . A plurality of support columns 15 are provided at the bottom of the support platform 2 , and a support base 16 is provided in the middle of the support columns 15 .

[0043] The shell 3 is arranged in the middle of the support platform 2. The lower end of the shell 3 is open and the middle is hollowed out to form an installation chamber 17. A rotating plate 11 is provided at the lower end of the shell 3. The rotating plate 11 is installed on the support base 16. The support base 16 allows the rotating plate 11 to rotate on it.

[0044] Multiple isolation blocks 18 are positioned within the housing 3, forming sliding areas 19 between the isolation blocks 18. The size of the sliding areas 19 matches the width of the sliding blocks 20, and the center of the isolation blocks 18 forms a movable area 21 for the rotation of the drive mechanism 4. The rotatable drive mechanism 4 pushes the push rod 34, maintaining the sliding block 20 in the center of the sliding area 19, and pushing the test piece 8 into contact with the lead-acid battery 1.

[0045] The drive mechanism 4 is disposed within the mounting chamber 17 and includes a motor 10, a rotating shaft 22, and a driving member 23. The motor 10 is mounted at the upper end of the housing 3. The rotating shaft 22 is located within the mounting chamber 17 and connected to the motor 10 at its upper end. A gear 24 is mounted on the rotating shaft 22, and the driving member 23 is provided with a rack 25 that mates with the gear 24. The rack 25 is connected to the driving member 23 via a connecting portion 26. The driving member 23 is mounted on the rotating plate 11 via a fixing block 27. The fixing block 27 has a sliding hole 28 formed therein, through which the driving member 23 slides.

[0046] The gear member 24 is a half gear having only normal teeth, so as to prevent the motor 10 from pushing the rack 25 excessively.

[0047] One end of the driving member 23 has a sliding portion 29 disposed in the sliding hole 28. The sliding portion 29 is provided with a first blocking member 30. A first spring 31 is sleeved on the sliding portion 29. One end of the first spring 31 contacts the first blocking member 30, and the other end contacts the fixed block 27. The driving member 23 is provided with a receiving groove 32 for accommodating the rotating shaft 22. The receiving groove 32 is strip-shaped. The strip-shaped receiving groove 32 allows the gear member 24 on the rotating shaft 22 to drive the rack 25 to move, thereby maintaining the receiving groove 32 on the driving member 23 to move, thereby allowing the rotating shaft 22 to move relative to the receiving groove 32. The other end of the driving member 23 is provided with a pushing column 33. The pushing column 33 is used to push the pushing rod 34, causing the second spring 35 on the pushing rod 34 to compress, so that the test piece 8 contacts the lead-acid battery 1.

[0048] Multiple test assemblies 5 are mounted on the housing 3. One end of each test assembly 5 is positioned within the mounting chamber 17, while the other end extends outside the housing 3. The test assembly 5 includes a test piece 8 and a push rod 34. The test piece 8 has symmetrically arranged contact members 36, with a contact area 37 formed in the middle of each contact member 36. The contact member 36 comprises a mounting portion 38, a corrugated portion 39, and an arcuate portion 40, with the arcuate portion 40 facing away from the contact area 37.

[0049] The distance between the first electrode 6 and the second electrode 7 is greater than the distance between the contact areas 37 . A scanner 9 is also provided on the test piece 8 .

[0050] The housing 3 has a through hole 41 through which the push rod 34 passes. One end of the push rod 34 extends through the through hole 41 to the outside of the housing 3. The portion of the push rod 34 extending outside the housing 3 is provided with a threaded portion 42. The test piece 8 has a threaded hole 43 that mates with the threaded portion 42. The threaded portion 42 is also provided with an adjustment member 44. The adjustment member 44 is located outside the housing 3 and can be rotated on the threaded portion 42 to change the distance between the threaded portion 42 and the interior of the housing 3, thereby changing the compression amount of the second spring 35.

[0051] The push rod 34 is further provided with a sliding block 20 , which is arranged inside the housing 3 . The push rod 34 is also provided with a second spring 35 , one end of the second spring 35 contacts the inner wall of the housing 3 , and the other end contacts the sliding block 20 .

[0052] An internal gear 70 is mounted on the rotating plate 11. A stopper region 45 is formed in the center of the internal gear 70. Multiple tooth grooves 46 are located on the inner wall of the internal gear 70. These tooth grooves 46 consist of vertical surfaces 47, perpendicular surfaces 48, and inclined surfaces 49. The perpendicular surfaces 48 are arranged at a 90-degree angle to the vertical surfaces 47. First teeth 50 are formed between the tooth grooves 46. These first teeth 50 all face in one direction, making the entire internal gear 70 a one-way gear 24.

[0053] A rotating member 51 is provided on the rotating shaft 22. A hinged member 52 is provided on the rotating member 51. A hinged port 53 is provided on the hinged member 52. The hinged port 53 is arc-shaped with an angle less than 180° to facilitate the installation of a movable member 54. A one-way movable member 54 is provided in the hinged port 53 and is mounted on the hinged member 52 via a hinge shaft 55.

[0054] The movable member 54 is composed of a rotating portion 56 and a movable portion 57. The movable portion 57 is arc-shaped and comprises a contact surface 58, an outer arc surface 59, and an inner arc surface 60. The contact surface 58 contacts the vertical surface 47. The hinge portion 53 is provided with a first blocking surface 61 that cooperates with the outer arc surface 59 and a second blocking surface 62 that cooperates with the inner arc surface 60. The first blocking surface 61 and the second blocking surface 62 are used to limit the rotation angle of the movable portion 57.

[0055] The movable portion 57 is provided with a hinge hole 63, in which a positioning member 64 is disposed. A stopper 65 is provided on one side of the hinged member 52, with a stopper opening 66 formed in the middle of the stopper 65. One end of the positioning member 64 is hinged in the hinge hole 63, and the other end is positioned in the stopper opening 66, allowing the positioning member 64 to move within the stopper opening 66. The stopper opening 66 forms a ring with the c-surface of the rotating member 51.

[0056] The positioning member 64 consists of a positioning section 67 , a connecting section 68 and a hinge section 69 . The connecting section 68 is used to connect the positioning section 67 with the hinge section 69 . The positioning section 67 is located in the limiting opening 66 , and the hinge section 69 is located in the hinge hole 63 .

[0057] like Figure 14 As shown, when the movable member 54 rotates from position M to position N, the inner arc surface 60 can be kept blocked by the second blocking surface 62. Since the internal gear member 70 is stationary, the rotating member 51 is driven to rotate by the rotating shaft 22. When the rotating shaft 22 rotates counterclockwise, the movable member 54 is blocked by the inclined surface 49, keeping the movable member 54 from rotating from position M to position N, thereby keeping the positioning member 64 rotated accordingly.

[0058] like Figure 14 As shown, F is an auxiliary circle, indicating that the hinge hole 63 on the movable member 54 rotates about the center of the hinge axis 55. Because the movable portion 57 is blocked by the inclined surface 49 and moves from position M to position N, the hinge hole 63 also rotates about the hinge axis 55, allowing the positioning section 67 of the positioning member 64 to move within the stop opening 66 from end a to end b. There is a height difference H between the movable portion 57 at position M and the movable portion 57 at position N, and this height difference H is less than the height of the stop opening 66.

[0059] In addition, in order to ensure that the positioning segment 67 is always at the a end, a return spring (not shown in the figure) is added between the b end and the positioning segment 67. After the positioning segment 67 is subjected to force and reaches the b end, the return spring can push the positioning segment 67 to return to its original position, so that when the rotating shaft 22 rotates, the movable part 57 can continue to be matched with the tooth groove 46.

[0060] When the rotating shaft 22 rotates clockwise, the contact surface 58 will contact the vertical surface 47. At this time, the positioning section 67 on the positioning member 64 is at the a end, and is thus restricted by the position of the limiting opening 66. At this time, the limiting member 65 will pull the positioning member 64, and the positioning member 64 will limit the position of the movable part 57, keeping the contact surface 58 pushing the vertical surface 47, so that the internal gear member 70 drives the rotating plate 11 to rotate a certain angle.

[0061] Motor 10 is a stepper motor 10. When operating, it maintains forward and reverse rotation. This allows counterclockwise rotation, which in turn drives rack 25 via gear 24, thereby allowing drive member 23 to push test assembly 5 into contact with lead-acid battery 1, enabling testing. After testing is complete, motor 10 rotates in the reverse direction, causing contact surface 58 on movable member 54 to push vertical surface 47, maintaining internal gear 70 to drive rotating plate 11 to rotate a certain angle, allowing drive mechanism 4 to reach the next test assembly 5, and then rotate counterclockwise.

[0062] Since the movable part 54 pushes the vertical surface 47 in the tooth groove 46 to move when rotating clockwise, and is pushed by the inclined surface 49 when rotating counterclockwise, the positioning rod is kept moving in the limit opening 66 and the movable part 54 is not kept pushing the internal gear part 70.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
