It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0032] The terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] In the description of the embodiments of the present utility model, the term "and / or" means and encompasses any and all possible combinations of one or more of the associated listed items. The term "and / or" is a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present utility model generally represents an "or" relationship between the associated objects before and after.

[0034] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, "coupling" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device including such element.

[0036] Currently, in the field of new energy vehicles, when a new energy vehicle comes off the production line, it is necessary to perform a charging test on its battery and then assemble the battery to ensure the durability and safety of the battery.

[0037] However, in the existing charging detection devices, the structure for disassembling the battery is complex, and the installation and disassembly steps are cumbersome, which greatly reduces the work efficiency of the testers.

[0038] To solve the above technical problems, please refer to Figure 1 , the present application provides a new energy vehicle battery charging detection device 100. The battery charging detection device 100 may include a detection device main body 110 and a detection table 120. The detection table 120 is communicatively connected to the detection device main body 110. Specifically, the detection table 120 may be electrically connected to the detection device main body 110.

[0039] The battery is installed on the detection table 120. Through the communicative connection between the detection table 120 and the detection device main body 110, the detection data of the battery is transmitted to the detection device main body 110, and the data is visualized for easy observation by the testers.

[0040] The testing platform 120 may be disposed on the testing device body 110 to improve the integrity of the battery charging testing device 100 .

[0041] Please continue reading Figure 1 and Figure 2 The detection platform 120 may include a detection platform body 121, and the detection platform body 121 may include a side wall 1211 and a bottom wall 1212. It can be understood that the side wall 1211 is formed as a peripheral wall of the detection platform body 121, and the bottom of the side wall 1211 is connected to the bottom wall 1212. The side wall 1211 and the bottom wall 1212 jointly define the internal space of the detection platform body 121. The side wall 1211 is provided with a strip hole 1213, and the strip hole 1213 passes through the side wall 1211. The strip hole 1213 is along the first direction (for example Figure 2 The side wall 1211 extends in a direction indicated by an arrow in the middle, wherein the side wall 1211 includes a bottom edge close to the bottom wall 1212 and an upper edge away from the bottom wall 1212, and the first direction is parallel to the direction from the upper edge toward the lower edge.

[0042] Please continue reading Figure 2 and Figure 3 The testing platform 120 may further include a first clamping portion 122, a second clamping portion 123, a connecting rod 124 and an elastic member 125. The first clamping portion 122 is disposed on the side wall 1211. Specifically, the first clamping portion 122 may be welded to the side wall 1211, or may be fixed to the side wall 1211 by a fastener. The second clamping portion 123 is located on the side of the first clamping portion 122 facing the bottom wall 1212, and is disposed opposite to the first clamping portion 122 in the first direction, and the battery is clamped between the first clamping portion 122 and the second clamping portion 123.

[0043] One end of the connecting rod 124 is connected to the second clamping portion 123, and the other end passes through the strip hole 1213 and extends to the interior of the detection platform body 121. The connecting rod 124 can slide along the first direction; the elastic member 125 is located inside the detection platform body 121, and one end of the elastic member 125 abuts against the bottom wall 1212, and the other end abuts against the connecting rod 124.

[0044] Among them, the elastic member 125 always applies a thrust to the connecting rod 124 away from the bottom wall 1212. Specifically, the elastic member 125 can be a spring. In this way, the elastic member 125 pushes the connecting rod 124 to move away from the bottom wall 1212, and the connecting rod 124 drives the second clamping portion 123 to move toward the second clamping portion 123, clamping the battery between the first clamping portion 122 and the second clamping portion 123. The strip hole 1213 limits the movement of the connecting rod 124, reduces the left and right shaking of the connecting rod 124, and avoids the second clamping portion 123 from being offset from the first clamping portion 122 during the movement.

[0045] During the installation of the battery, the tester pushes the second clamping portion 123 towards the bottom wall 1212 so that the distance between the first clamping portion 122 and the second clamping portion 123 is greater than the length of the battery. Then, the battery is placed between the first clamping portion 122 and the second clamping portion 123. After releasing the second clamping portion 123, the elastic member 125 pushes the second clamping portion 123 towards the first clamping portion 122 through the connecting rod 124 until the first clamping portion 122 and the second clamping portion 123 clamp the battery. Then, the battery is subjected to a charging test.

[0046] After the battery test is completed, the tester again pushes the second clamping portion 123 towards the bottom wall 1212 so that the distance between the first clamping portion 122 and the second clamping portion 123 is greater than the length of the battery. The battery is removed, and then the second clamping portion 123 is released.

[0047] In summary, through the battery charging detection device 100 provided by the present application, the structure for installing and disassembling the battery is simplified, the operation is simple, and the working efficiency of the tester is greatly improved.

[0048] Among them, please continue to refer to Figure 3 The second clamping portion 123 includes a vertical plate 1231. The vertical plate 1231 is connected to the connecting rod 124. The width of the vertical plate 1231 is greater than the width of the strip-shaped hole 1213. Thus, by setting the vertical plate 1231, it is possible to prevent the second clamping portion 123 from extending into the strip-shaped hole 1213, thereby reducing the lateral movement of the second clamping portion 123 and ensuring the stability of the second clamping portion 123 during the movement process.

[0049] In some embodiments of the present invention, please refer to Figure 2 and Figure 3 The detection table 120 may further include a limiting cylinder 126. The limiting cylinder 126 is located inside the detection table main body 121. The limiting cylinder 126 extends in the first direction. The elastic member 125 is located inside the limiting cylinder 126. In this way, by placing the elastic member 125 inside the limiting cylinder 126, the circumferential dimension of the limiting cylinder 126 is adapted to the circumferential dimension of the elastic member 125, which can prevent the elastic member 125 from swinging during the compression and elongation processes, further ensuring the stability of the elastic member 125 during use, and thus ensuring the stability of the battery charging detection device 100 during use.

[0050] Specifically, the first side wall 1211 and the bottom wall 1212 are inclined. The strip-shaped hole 1213 is provided on the first side wall 1211. The extending direction of the strip-shaped hole 1213 is consistent with the inclined direction of the first side wall 1211 (for example Figure 3 the direction indicated by the arrow in

[0051] In this way, by arranging the first side wall 1211 and the bottom wall 1212 in an inclined manner, it is convenient for the assembly and disassembly of the battery. By making the extending direction of the limiting cylinder 126 consistent with the inclined direction of the first side wall 1211, the deformation direction of the elastic member 125 is made consistent with the inclined direction of the first side wall 1211, which can improve the stability during the movement of the second clamping portion 123 and at the same time improve the conversion efficiency of the elastic potential energy of the elastic member 125.

[0052] In some embodiments of the present application, please continue to refer to Figure 3 , the connecting rod 124 includes a first rod section 1241 and a second rod section 1242. One end of the first rod section 1241 is connected to the second clamping portion 123, and the other end passes through the strip-shaped hole 1213 and extends into the interior of the detection table main body 121. One end of the second rod section 1242 is connected to the first rod section 1241, and the other end extends into the limiting cylinder 126 and abuts against the elastic member 125; wherein, the extending direction of the second rod section 1242 is consistent with the first direction.

[0053] Thus, by providing the second rod section 1242 extending into the limiting cylinder 126, it is possible to prevent the connecting rod 124 from disengaging from the limiting cylinder 126 during movement, further ensuring the stability of the second clamping portion 123 during movement.

[0054] In some embodiments of the present application, please continue to refer to Figure 3 , the detection table 120 may further include a sliding block 127. The sliding block 127 is clamped between the second rod section 1242 and the elastic member 125, that is to say, one end of the sliding block 127 abuts against the second rod section 1242, and the other end abuts against the elastic member 125.

[0055] Among them, the sliding block 127 is adapted to the limiting cylinder 126. By providing the sliding block 127, the elastic member 125 can be further ensured, the force-bearing area of the second rod section 1242 can be increased, thereby ensuring the stability of the movement of the connecting rod 124, and further ensuring the stability of the second clamping portion 123 during movement.

[0056] In some embodiments of the present application, please refer to Figure 4 and Figure 5 , the battery charging detection device 100 may further include a battery protection fence 130. The battery protection fence 130 is located between the first clamping portion 122 and the second clamping portion 123. The battery protection fence 130 surrounds the circumferential outer side of the battery. The battery protection fence 130 includes a fixed end facing the second clamping portion 123, and the fixed end is detachably connected to the second clamping portion 123. Thus, by providing the battery protection fence 130 to limit the circumference of the battery, it is possible to prevent the battery from falling off during the battery detection process.

[0057] In some embodiments of the present application, in the first direction (for exampleFigure 4 in the direction indicated by the arrow, the length of the battery protection shroud 130 is greater than or equal to 20 mm and less than or equal to 30 mm.

[0058] In a specific implementation process, the length of the battery protection shroud 130 can be 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, 30 mm, etc. In this way, while ensuring the circumferential stability of the battery, the volume of the battery protection shroud 130 can be reduced, the use of raw materials for the battery protection shroud 130 can be reduced, and the cost can be lowered.

[0059] It should be noted that the length of the battery is generally 65 mm. Setting the length of the battery protection shroud 130 to 20 mm can meet the circumferential stability of the battery.

[0060] In some embodiments of the present application, please continue to refer to Figure 5 , the battery protection shroud 130 can include a first shroud 131 close to the side wall 1211 and a second shroud 132 away from the side wall 1211. In the circumferential direction of the battery, the first shroud 131 and the second shroud 132 are arranged in sequence, and the first shroud 131 and the second shroud 132 are detachably connected.

[0061] Thus, when the battery is installed, the second shroud 132 can be detached first, then the battery can be assembled to the first shroud 131, and then the second shroud 132 is connected to the first shroud 131 to protect the circumference of the battery; when the battery is disassembled, the second shroud 132 is detached first, and then the battery can be taken out.

[0062] In some embodiments of the present application, please continue to refer to Figure 5 , the first shroud 131 can include a first edge 1311 and a second edge, the second shroud 132 can include a third edge 1321 and a fourth edge, the first edge 1311 is opposite to the third edge 1321, and the second edge is opposite to the fourth edge.

[0063] Among them, it can be that a clamping protrusion 134 is provided on the first edge 1311, and a clamping groove 133 cooperating with the clamping protrusion 134 is provided on the third edge 1321.

[0064] It can also be that a clamping protrusion 134 is provided on the third edge 1321, and a clamping groove 133 cooperating with the clamping protrusion 134 is provided on the first edge 1311.

[0065] It can also be that a clamping protrusion 134 is provided on the second edge, and a clamping groove 133 cooperating with the clamping protrusion 134 is provided on the fourth edge.

[0066] Alternatively, a clamping protrusion 134 may be provided on the fourth edge, and a clamping groove 133 that cooperates with the clamping protrusion 134 is provided on the fourth edge.

[0067] Thus, by providing the mutually cooperating clamping protrusion 134 and clamping groove 133, the detachable connection between the first surrounding plate 131 and the second surrounding plate 132 is realized.

[0068] In some embodiments of the present application, please continue to refer to Figure 5 , the clamping groove 133 may include a clamping opening 1331 facing the clamping protrusion 134, the clamping protrusion 134 may include a body portion 1341 facing the clamping groove 133 and a connecting portion 1342 away from the clamping groove 133. Among them, the size of the clamping opening 1331 is larger than the size of the connecting portion 1342 and smaller than the size of the body portion 1341.

[0069] Thus, the clamping protrusion 134 can enter from one end of the clamping groove 133, the body portion 1341 is located in the clamping groove 133, and the connecting portion 1342 cooperates with the clamping opening 1331 to realize the clamping between the clamping protrusion 134 and the clamping groove 133, and further realize the clamping between the first surrounding plate 131 and the second surrounding plate 132.

[0070] Specifically, the clamping protrusion 134 can enter the clamping groove 133 from the clamping opening 1331.

[0071] In some other embodiments, please refer to Figure 5 , a clamping groove 133 is provided on the first edge 1311, a clamping protrusion 134 is provided on the third edge 1321. The clamping groove 133 extends along the length direction of the first edge 1311 and penetrates through the first surrounding plate 131. The clamping protrusion 134 extends along the length direction of the third edge 1321, and the connecting portion 1342 connects the body portion 1341 to the third edge 1321. The clamping protrusion is inserted into the clamping groove 133 from one end port of the clamping groove 133. Thus, the clamping between the first surrounding plate 131 and the second surrounding plate 132 is realized.

[0072] In some embodiments of the present application, in the first direction, the length of the first surrounding plate 131 is less than the length of the second surrounding plate 132. Since the first surrounding plate 131 is disposed close to the side wall 1211, the side wall 1211 can play a role in protecting the circumferential stability of the battery. Reducing the length of the first surrounding plate 131 can further reduce the raw materials and costs.

[0073] The above are only specific embodiments of the present invention, enabling those skilled in the art to understand or implement the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments described herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
