[0028] First embodiment

[0029] Please refer to Figure 1 The present embodiment provides a battery connection test device 100, which is used to act as an intermediate medium to connect the tab 11 and the current line of the tester. The battery connection test device 100 includes two clamping mechanisms 200. The two clamping mechanisms 200 are used to clamp the positive and negative tabs 11 of the battery 10 respectively.

[0030] Optionally, in this embodiment, the tabs 11 of the battery 10 are all arranged horizontally, and the pressing direction of the corresponding pressing mechanism is perpendicular to the tabs 11. In other embodiments, the tabs 11 of the battery 10 can be arranged in any plane, such as a vertical plane. It is sufficient to ensure that the pressing direction of the pressing mechanism 200 is perpendicular to the tabs 11 of the battery 10, and the utility model does not limit this.

[0031] It can be understood that in this embodiment, the positions of the first conductive plate 21 and the second conductive plate 31 can be freely adjusted, so that their clamping positions can also be adjusted, and the tabs 11 of batteries 10 of different sizes can be clamped. It is suitable for batteries 10 of different sizes and has strong versatility.

[0032] Please refer to Figure 2 The clamping mechanism 200 includes a clamping mechanism 200 body and a first clamping assembly 20 and a second clamping assembly 30 connected to the clamping mechanism 200 body. The first clamping assembly 20 includes a first driving member (not shown) and a first conductive plate 21. The second clamping assembly 30 includes a second driving member (not shown) and a second conductive plate 31. The first driving member can drive the first conductive plate 21 to move relative to the clamping mechanism 200 body, and the second driving member can drive the second conductive plate 31 to move relative to the clamping mechanism 200 body, so that the first conductive plate 21 and the second conductive plate 31 can move toward or away from each other. At least one of the first conductive plate 21 and the second conductive plate 31 is provided with a connecting hole 311 for connecting the current line of the tester.

[0033] It can be understood that the first conductive plate 21 and the second conductive plate 31 are both metal plates, which are used to contact and conduct electricity with the pole lug 11. When the pole lug 11 needs to be clamped and fixed, the pole lug 11 is placed between the first conductive plate 21 and the second conductive plate 31, and the first conductive plate 21 and the second conductive plate 31 are driven to move toward each other until the first conductive plate 21 and the second conductive plate 31 clamp the pole lug 11. When the test is completed, the first conductive plate 21 and the second conductive plate 31 are driven to move away from each other, thereby releasing the pole lug 11.

[0034] Optionally, in this embodiment, the connection hole 311 is provided on the second conductive plate 31. In other embodiments, the connection hole 311 may be provided on the first conductive plate 21, which is not limited in the present invention.

[0035] Specifically, the body of the clamping mechanism 200 is a frame structure, which includes a top frame 40, a first side frame 41, a bottom frame 43 and a second side frame 42 connected in sequence. It can be understood that the top frame 40, the first side frame 41, the second side frame 42 and the bottom frame 43 together form the body of the clamping mechanism 200.

[0036] The first pressing assembly 20 further includes a first connecting member 22. The first connecting member 22 is a column structure. One end of the first connecting member 22 is fixedly connected to the first conductive plate 21, and the other end is slidably disposed in the top frame 40. The first connecting member 22 is drivingly connected to the first driving member.

[0037] It is understandable that a through hole is provided on the top frame 40, and the first connecting member 22 passes through the through hole and can slide relative to the top frame 40. Specifically, in this embodiment, the first driving member is an electric cylinder or an electric push rod, and in other embodiments, the first driving member can be a gear motor and a rack, which is not limited in the present invention.

[0038] Furthermore, the first connecting member 22 is provided with a first slide rail 221. The top frame 40 is provided with a notch (not shown) that cooperates with the first slide rail 221. It can be understood that the first slide rail 221 is a protruding structure that can cooperate with the notch on the top frame 40, thereby limiting the first connecting member 22 from rotating and also playing a guiding role.

[0039] Optionally, in this embodiment, the first connecting member 22 is cylindrical, and in other embodiments, the first connecting member 22 may be a square column or a polygonal column, which is not limited in the present invention.

[0040] In order to conveniently control the movement of the first clamping assembly 20, in this embodiment, a first control button 23 for controlling the operation of the first driving member is provided on the top frame 40. It can be understood that the first clamping assembly 20 in this embodiment is electrically controlled, and the first control button 23 is electrically connected to the first driving member, and can control the first connecting member 22 to drive the first conductive plate 21 to rise or fall.

[0041] The second clamping assembly 30 also includes a second connecting member 32. The second connecting member 32 is fixedly connected to the second conductive plate 31, and is slidably connected to the first side frame 41 and the second side frame 42. The second connecting member 32 is transmission-connected to the second driving member. Specifically, the first side frame 41 and the second side frame 42 are both provided with a second slide rail 44. The second connecting member 32 is connected to both sides of the second conductive plate 31 and extends into the second slide rail 44. The portion of the second connecting member 32 extending into the second slide rail 44 can slide in the second slide rail 44, thereby driving the second conductive plate 31 to move up and down.

[0042] Optionally, the second driving member is an electric cylinder or an electric push rod. In other embodiments, the second driving member can be a gear motor and a rack, which is not limited in the present invention.

[0043] In order to conveniently control the movement of the second clamping assembly 30, a second control button 33 for controlling the operation of the second driving member is provided on one of the first side frame 41 and the second side frame 42. In this embodiment, the second control button 33 is provided on the second side frame 42. In other embodiments, the second control button 33 may be provided on the first side frame 41, which is not limited by the present utility model. It is understandable that the second clamping assembly 30 in this embodiment is in the form of electric control, and the second control button 33 is electrically connected to the second driving member, and can control the second connecting member 32 to drive the second conductive plate 31 to rise or fall.

[0044] Furthermore, a fixing hole 431 is provided on the main body of the clamping mechanism 200. In the present embodiment, the fixing hole 431 is provided on the bottom frame 43. The clamping mechanism 200 can be fixed to other structures by passing bolts and nuts through the fixing hole 431, thereby playing a fixing role. When multiple channels are connected in parallel to the pole ears 11, the battery 10 may fall over due to uneven force. The utility model provides a fixing hole 431 at the bottom of the clamping mechanism 200, which can fix the battery 10 through the clamping mechanism 200 to avoid the problem of the battery 10 falling over.

[0045] The working principle and process of the battery connection test device 100 provided in the embodiment of the utility model are:

[0046] When it is necessary to perform a charge and discharge test on the battery 10, the two clamping mechanisms 200 are placed at the positions of the positive and negative tabs 11 of the battery 10 according to the size of the battery 10. The positive and negative tabs 11 of the battery 10 are respectively inserted between the first conductive plate 21 and the second conductive plate 31 so that they can be covered by the first conductive plate 21 and the second conductive plate 31. The first conductive plate 21 is controlled to move downward by the first control button 23 until it fits with the tab 11. The second conductive plate 31 is controlled to move upward by the second control button 33 until it fits with the tab 11, thereby achieving the clamping of the tab 11 by the first conductive plate 21 and the second conductive plate 31. Bolts are passed through the fixing holes 431 on the bottom frame 43 and tightened with nuts. The current lines of the positive and negative poles of the tester are respectively connected to the connection holes 311 on the two second conductive plates 31, and bolts are passed through the connection holes 311 and fixed with nuts. Finally, the first conductive plate 21 and the second conductive plate 31 are fine-tuned by the first control button 23 and the second control button 33 so that the tab 11 cannot move, and the connection between the tester current line and the tab 11 is completed, and then the test can be carried out.

[0047] After the test is completed, the first conductive plate 21 is raised by the first control button 23, and the second conductive plate 31 is lowered by the second control button 33, thereby releasing the tab 11. The battery 10 is replaced, and then the next battery 10 is tested.

[0048] The advantageous effects of the clamping mechanism 200 of the battery connection test device 100 provided by the embodiment of the utility model are:

[0049] The clamping mechanism 200 of the battery connection test device 100 includes a clamping mechanism 200 body and a first clamping assembly 20 and a second clamping assembly 30 connected to the clamping mechanism 200 body. The first clamping assembly 20 includes a first driving member and a first conductive plate 21. The second clamping assembly 30 includes a second driving member and a second conductive plate 31. The first driving member can drive the first conductive plate 21 to move relative to the clamping mechanism 200 body, and the second driving member can drive the second conductive plate 31 to move relative to the clamping mechanism 200 body, so that the first conductive plate 21 and the second conductive plate 31 can move toward or away from each other. At least one of the first conductive plate 21 and the second conductive plate 31 is provided with a connecting hole 311. The clamping mechanism 200 can separate the pole lug 11 from the tester current line by connecting the tester current line to the conductive plate through the connecting hole 311 and connecting to the pole lug 11 through the conductive plate, thereby simplifying the steps of connecting and tightening the bolts, avoiding the situation where the pole lug 11 is broken due to direct connection and multiple disassembly, improving work efficiency, and being applicable to batteries 10 of different sizes with strong versatility.
