[0048] As Figure 1 and Figure 2 As shown, an embodiment of the present application provides a battery test fixture 100, which is mainly used to form a double clamping and fixing of the battery 200, facilitating the electrical detection of the battery 200. The battery test fixture 100 includes a fixed frame 130, a longitudinal fixing component 110 and a transverse fixing member.

[0049] The longitudinal fixing component 110 includes a support member 111 and a lifting member 112. The support member 111 is connected to the fixed frame 130, and the lifting member 112 is movably connected to the fixed frame 130, so that the lifting member 112 moves relative to the support member 111 along the first direction D1 to limit and fix the first direction D1 of the battery 200, forming a first fixation.

[0050] The transverse fixing component 120 is arranged on the support member 111, making the structure of the battery test fixture 100 more compact and reducing the volume.

[0051] The transverse fixing component 120 is used to fix the battery 200 along the second direction D2, limit and fix the second direction D2 of the battery 200, forming a second fixation, and improving the accuracy of the test result of the battery 200.

[0052] The first direction D1, the second direction D2 and the third direction D3 are perpendicular to each other in pairs. Exemplarily, as Figure 1As described above, the first direction D1 is the height direction of the fixing frame 130, that is, the up and down direction, the second direction D2 is the thickness direction of the fixing frame 130, that is, the front and back direction, and the third direction D3 is the width direction of the fixing frame 130, that is, the left and right direction. In other attached drawings, the first direction D1, the second direction D2, and the third direction D3 should be adjusted adaptively.

[0053] As Figure 5 shown, in some embodiments, the horizontal fixing assembly 120 includes a movable plate 121 and a first fixing plate 122.

[0054] The movable plate 121 and the first fixing plate 122 are arranged in parallel at intervals along the second direction D2 to define a battery placement area 127. The movable plate 121 can move relative to the first fixing plate 122 along the second direction D2. In this way, according to the actual size of the battery 200 to be tested, the distance between the movable plate 121 and the first fixing plate 122 can be adjusted, so that the battery test fixture 100 can be applicable to more models of batteries 200, improving the practicability.

[0055] During the testing process of the battery 200, there is a problem that the battery 200 may experience thermal runaway. The rapid rise in the temperature of the battery 200 not only affects the life and safety of the battery 200 itself, but also poses a risk of fire or explosion.

[0056] When testing the battery in the related art, the battery is usually placed in a forward-fixed manner, that is, the electrode surface of the battery faces upward. In this way, when thermal runaway occurs, it is impossible to quickly exhaust and relieve pressure inside the lower box of the battery, posing a safety hazard of battery thermal runaway.

[0057] To address the above problems, as Figure 1 and Figure 4 shown, in some embodiments, the support member 111 includes a support plate 1111. The horizontal fixing assembly 120 is arranged on the support plate 1111. The support plate 1111 is formed with a concave area 1112 relative to the battery placement area 127, and the concave area 1112 communicates with the battery placement area 127. In this way, the battery 200 can be placed in the horizontal fixing assembly 120, and the electrode surface of the battery 200 faces downward and is exposed in the concave area 1112, facilitating electrolysis of the battery 200 electrodes through the concave area 1112.

[0058] In addition, by inverting the battery 200, it is possible to quickly exhaust and relieve pressure inside the lower box when the battery 200 experiences thermal runaway, eliminating the safety hazard of battery 200 thermal runaway.

[0059] As Figure 4As shown, the concave area 1112 is generally C-shaped, making the support plate 1111 generally U-shaped. The concave area 1112 is arranged below the battery placement area 127. In this way, sufficient space can be reserved for electrical connection operations of the battery 200, improving the test efficiency.

[0060] In other embodiments, the concave area 1112 can also be V-shaped, rectangular, etc. The concave area 1112 communicates with the battery placement area 127, causing the battery 200 to be inverted, facilitating the access of wires from below for electrical testing.

[0061] As Figure 3 shown, the fixing frame 130 includes four fixing columns 131 arranged in a rectangle. An L-shaped connecting block 133 is provided at the bottom end of each fixing column 131, facilitating the connection of the fixing frame 130 to an external fixing platform and improving the overall stability of the battery test fixture 100.

[0062] As Figure 4 shown, in some embodiments, the support plate 1111 includes a first sub-support plate 11111 and a second sub-support plate 11112.

[0063] Among them, the first sub-support plate 11111 is arranged below the second sub-support plate 11112, and the first sub-support plate 11111 is connected to the fixing column 131 of the fixing frame 130.

[0064] A first long circular hole 11113 is formed on the first sub-support plate 11111 along the first direction D1. A connection hole is formed at the position of the fixing column 131 corresponding to the first long circular hole 11113. The first sub-support plate 11111 and the fixing column 131 are connected by bolts. In this way, the first sub-support plate 11111 can be adjusted along the first direction D1, which is beneficial for the longitudinal fixing assembly 110 to fix batteries 200 of different sizes and improve the stability of the fixed battery 200.

[0065] The second sub-support plate 11112 is an insulating plate. In this embodiment, the second sub-support plate 11112 is a phenolic resin plate. The phenolic resin plate, that is, the bakelite plate, has good electrical insulation, heat resistance, dimensional stability, and mechanical strength. In other embodiments, heat-resistant insulating plates such as ceramic plates can also be used.

[0066] In some embodiments, an avoidance groove 1221 is provided on one side of the first fixing plate 122 close to the concave area 1112.

[0067] Specifically, as Figure 5 shown, the avoidance groove 1221 of the first fixing plate 122 is generally U-shaped and the opening faces the concave area 1112, facilitating the exposure of the electrode surfaces of different types of batteries 200 and facilitating subsequent electrical connection operations for testing, improving the test efficiency.

[0068] In other embodiments, the avoidance groove 1221 can also be V-shaped, rectangular, etc. The avoidance groove 1221 communicates with the battery placement area 127, prompting the battery 200 to be inverted, facilitating the access of wires from below for electrical testing.

[0069] In this embodiment, an avoidance groove 1221 is also provided on the side of the first fixing plate 122 away from the recessed area 1112. There is no need to install the movable plate 121 in a distinguished direction, improving the assembly efficiency of the horizontal fixing component 120.

[0070] Such as Figure 4 As shown, in some embodiments, the support member 111 further includes a first heat dissipation plate 1113, and the first heat dissipation plate 1113 is used to dissipate heat from the electrode surface of the battery 200.

[0071] The first heat dissipation plate 1113 is disposed on the side of the support plate 1111 close to the horizontal fixing component 120. The first heat dissipation plate 1113 is movably disposed on the support plate 1111, and the first heat dissipation plate 1113 can move along the third direction D3.

[0072] In this embodiment, the number of the first heat dissipation plates 1113 is two. One first heat dissipation plate 1113 is in contact with the positive electrode surface of the battery 200, and the other first heat dissipation plate 1113 is in contact with the negative electrode surface of the battery 200.

[0073] When performing electrical testing on the battery 200, it is necessary to electrically connect the positive and negative electrodes of the battery 200, which is likely to generate heat at the positive electrode post and the negative electrode post. It is necessary to dissipate heat from these two places.

[0074] In this embodiment, the first heat dissipation plate 1113 is a liquid cooling plate, and a bent pipeline filled with cooling water, as well as a water inlet and a water outlet, are arranged in the first heat dissipation plate 1113. In other embodiments, the first heat dissipation plate 1113 can also be a metal plate with good heat dissipation and thermal conductivity, such as a copper plate, and then cooperate with an air cooling device for effective heat dissipation.

[0075] Such as Figure 4 As shown, the support member 111 further includes a clamping plate 1114. The first heat dissipation plate 1113 is strip-shaped and is arranged along the second direction D2. The two first heat dissipation plates 1113 are arranged in parallel at intervals along the third direction D3 to prevent the two first heat dissipation plates 1113 from contacting and causing a short circuit.

[0076] One end of the first heat dissipation plate 1113 is clamped between the clamping plate 1114 and the support plate 1111, and the other end is disposed below the battery 200 prevention area. Second long circular holes 1115 are formed in the clamping plate 1114 and the support plate 1111 and are connected by bolts and nuts. When detecting batteries 200 of different models, the position of the bolt in the second long circular hole 1115 can be adjusted to move the first heat dissipation plate 1113, so that the first heat dissipation plate 1113 is in effective contact with the electrode surfaces of different models of batteries 200, improving the heat dissipation efficiency.

[0077] In some embodiments, the lateral fixing assembly 120 further includes a second fixing plate 123, a connecting rod 125, and a lateral driver 124.

[0078] As Figure 5 shown, the second fixing plate 123, the movable plate 121, and the first fixing plate 122 are sequentially arranged in parallel along the second direction D2.

[0079] The connecting rod 125 is arranged along the second direction D2 and connects the first fixing plate 122 and the second fixing plate 123. The movable plate 121 is slidably arranged on the connecting rod 125.

[0080] In this embodiment, the number of the connecting rods 125 is four, and the four connecting rods 125 are distributed in a rectangle and are connected to the four corners of the movable plate 121, the first fixing plate 122, and the second fixing plate 123, so that the battery placement area 127 is located in the middle position of the four connecting rods 125, improving the placement efficiency of the battery 200. At the same time, the structural stability of the lateral fixing assembly 120 can also be improved. In other embodiments, the number of the connecting rods 125 can be adjusted as required according to their set positions. For example, only two connecting rods 125 can be set and distributed diagonally to expand the volume of the battery placement area 127.

[0081] The lateral driver 124 drives the movable plate 121 to move in a direction close to or away from the first fixing plate 122.

[0082] Exemplarily, as Figure 5 shown, a cylinder is provided on the side of the second fixing plate 123 close to the movable plate 121, and the output end of the cylinder is fixedly connected to the movable plate 121.

[0083] Exemplarily, a threaded hole is formed in the second fixing plate 123, and the threaded rod passes through the threaded hole and is connected to the movable plate 121. By rotating the threaded rod, the position of the movable plate 121 is adjusted.

[0084] In some embodiments, as Figure 5As shown, the horizontal fixing component 120 further includes four fixing feet 126, two of which are connected to the first fixing plate 122 and are arranged at intervals along the third direction D3, and the remaining two fixing feet 126 are connected to the second fixing plate 123 and are arranged at intervals along the third direction D3. The four fixing feet 126 are generally distributed in a rectangle.

[0085] The horizontal fixing component 120 is arranged on the second sub-support plate 11112 through the four fixing feet 126, and the fixing feet 126 are arranged at intervals from the clamping plate 1114 to avoid interference.

[0086] In some embodiments, as Figure 6 shown, the lifting member 112 includes a longitudinal driver 1121 and a second heat dissipation plate 1122.

[0087] The second heat dissipation plate 1122 is used to dissipate heat from the bottom end face of the battery 200 placed upside down. By providing the first heat dissipation plate 1113 and the second heat dissipation plate 1122 to dissipate heat from the battery 200, the probability of thermal runaway of the battery 200 can be reduced and the test efficiency of the battery 200 can be improved.

[0088] In this embodiment, the number of the second heat dissipation plates 1122 is one, and the area of the second heat dissipation plate 1122 is slightly larger than the bottom end of the battery 200 to improve the heat dissipation efficiency. The second heat dissipation plate 1122 also adopts a liquid cooling plate, and a bent pipeline filled with cooling water, as well as a water inlet and a water outlet, are arranged in the second heat dissipation plate 1122. In other embodiments, the second heat dissipation plate 1122 can also adopt a metal plate with good heat dissipation and thermal conductivity, such as a copper plate, and cooperate with an air cooling device for effective heat dissipation.

[0089] The longitudinal driver 1121 drives the second heat dissipation plate 1122 to move in a direction close to or away from the support member 111.

[0090] Exemplarily, as Figure 1 and Figure 6 shown, the longitudinal driver 1121 is a mechanical manual rod, and pulling the handle drives the second heat dissipation plate 1122 to move.

[0091] The fixing frame 130 further includes a cross bar 132, which is connected to the top end of the fixing column 131 and is used to fix the longitudinal driver 1121.

[0092] Exemplarily, the longitudinal driver 1121 is a cylinder or a motor, and the output end of the cylinder or the motor is connected to the second heat dissipation plate 1122, so as to drive the second heat dissipation plate 1122 to move.

[0093] In some embodiments, the lifting member 112 further includes a connecting plate 1123.

[0094] As Figure 6As shown, the connecting plate 1123 is connected to the side of the second heat dissipation plate 1122 away from the support member 111, and the output end of the longitudinal driver is connected to the connecting plate 1123.

[0095] The connecting plate 1123 includes a first sub-connecting plate 11231 and a second sub-connecting plate 11232.

[0096] Exemplarily, the first sub-connecting plate 11231 is a metal plate, the second sub-connecting plate 11232 is a bakelite board, and the first sub-connecting plate 11231 is connected to the longitudinal driver 1121. By using the ductility of the metal plate, the two ends of the first sub-connecting plate 11231 are bent to snap and fix the second sub-connecting plate 11232 and the second heat dissipation plate 1122, making the structure of the lifting member 112 more compact.

[0097] In some embodiments, the lifting member 112 further includes a longitudinal slide rail 1124.

[0098] The longitudinal slide rail 1124 is arranged along the first direction D1, the longitudinal slide rail 1124 is fixed to the fixing frame 130, and the connecting plate 1123 is slidably arranged on the longitudinal slide rail 1124.

[0099] As Figure 1 and Figure 2 shown, in this embodiment, the number of longitudinal slide rails 1124 is 4. A longitudinal slide rail 1124 is provided at the upper end of each fixing column 131 of the fixing frame 130. Through holes 11233 are distributed at the four corners of the second sub-connecting plate 11232, and the longitudinal slide rail 1124 passes through the through holes 11233, so that the connecting plate 1123 is slidably arranged on the longitudinal slide rail 1124. In this way, the structure can be simplified and the processing cost of the connecting plate 1123 can be reduced.

[0100] In other embodiments, the number of longitudinal slide rails 1124 can be adjusted according to the position where it is set as required. For example, only two connecting rods 125 can be provided and distributed diagonally. It is also possible to realize the sliding connection between the connecting plate 1123 and the longitudinal slide rail 1124 by setting sliders on the second sub-connecting plate 11232.
