Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to battery assembly tooling. Background Technology

[0002] Cylindrical battery boxes typically consist of multiple battery modules arranged in parallel, each module comprising multiple cylindrical cells arranged in parallel, thus enabling the cylindrical battery box to have sufficient energy density. To meet the heat dissipation requirements of the cylindrical battery box, heat exchange plates are also required between adjacent battery modules.

[0003] In related technologies, when assembling cylindrical battery boxes, the heat exchange plate is typically placed directly between two battery modules, and two opposing clamps are used to clamp the battery modules and the heat exchange plate, thus bonding and fixing the heat exchange plate between the two battery modules. This assembly method can easily lead to displacement of the cylindrical batteries, thereby reducing the quality of the cylindrical battery box and even causing safety hazards. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figures 1 to 4 As shown, this embodiment provides a battery assembly fixture, including a base 1, two side pressure members 2, two carriers 3, a top pressure member 4, and a support member 5. The two side pressure members 2 are arranged opposite each other along a first direction and are slidably disposed on the base 1 along the first direction. The two carriers 3 are slidably disposed on the base 1 and located between the two side pressure members 2. The support member 5 is fixed to the base 1, and the top pressure member 4 is located above the carriers 3. The top pressure member 4 is vertically adjustable on the support member 5 and has a through groove 41 for the heat exchange plate of the battery to pass through. The through groove 41 is located between the two carriers 3.

[0026] In this embodiment of the battery assembly fixture, the carrier 3 is used to carry the battery module. The battery heat exchange plate can be inserted between two carriers 3 through the through slot 41, so that the heat exchange plate is clamped between the two battery modules. The two side pressure members 2 are driven to move relative to each other in the first direction by manual operation or opening and closing drive mechanism to clamp the two carriers 3 and the battery modules they carry, so that the heat exchange plate is bonded and fixed to the battery module. At the same time, the position of the top pressure member 4 in the vertical direction can be adjusted so that the top pressure member 4 abuts against the top of the battery module, thereby playing a positioning role for the battery module, which can avoid problems such as battery module displacement, and improve the battery assembly quality and efficiency.

[0027] It should be noted that batteries can store chemical energy and controllably convert it into electrical energy. In recyclable batteries, the active materials can be reactivated by charging after discharge, allowing for continued use.

[0028] Multiple battery cells (e.g., multiple battery cells with equal capacity and internal resistance) are connected in series or parallel to form a battery module. The battery module, battery management system (BMS), thermal management system, electrical connection system (high-voltage / low-voltage connectors, wiring harnesses, etc.), structural components (casing, brackets, etc.), and protective components are placed inside a battery box and sealed to form a complete functional unit that can directly output electrical energy; this is the battery pack. The battery pack, as a rechargeable battery, is the power source for new energy vehicles.

[0029] It is understandable that a battery pack may include one battery module, or it may include two, three, four, or even more battery modules. When a battery pack includes at least two battery modules, a heat exchange plate is provided between two adjacent battery modules. The surface of the heat exchange plate that contacts the battery module is coated with adhesive such as glue to bond and fix the heat exchange plate to the battery module.

[0030] Specifically, the heat exchange plate has a heat exchange channel inside, which is used to circulate the heat exchange medium. The heat exchange medium can be a gas (such as air), a liquid (such as water, alcohol, refrigerant, oil, etc.), or a solid (such as thermally conductive adhesive, thermally conductive solder paste, etc.). The heat exchange channel has an inlet and an outlet for the heat exchange medium. The heat exchange medium can enter the heat exchange channel through the inlet, and after exchanging heat with the battery cells, it can be discharged through the outlet, thus realizing the heat exchange of the battery cells.

[0031] In this embodiment, before the heat exchange plate is inserted into the through slot 41, the surface of the heat exchange plate has been pre-coated with adhesive. Then, when the heat exchange plate is inserted between the two battery modules, the heat exchange plate and the battery module can be bonded and fixed by clamping the battery module with the two side pressure members 2.

[0032] For example, the side pressure member 2 has a plate-like structure, which increases the contact area between the side pressure member 2 and the battery module, thereby improving the adhesion between the battery module and the heat exchange plate. Furthermore, the top pressure member 4 has a plate-like structure, which increases the contact area between the top pressure member 4 and the battery module, thereby improving the positioning stability of the battery module.

[0033] For example, both the side pressure member 2 and the carrier 3 are slidably mounted on the base 1 via slide rails.

[0034] In some embodiments, the battery assembly fixture further includes a check mechanism 6, which has a locked state and an unlocked state. In the locked state, the check mechanism 6 can prevent the two side pressure members 2 from approaching or moving away from each other; in the unlocked state, the side pressure members 2 can move along a first direction.

[0035] Specifically, after clamping the two battery modules and heat exchange plates by the two side pressure members 2, pressure holding is required. At this time, the check mechanism 6 can prevent the two side pressure members 2 from moving away from each other, so as to improve the convenience and reliability of the pressure holding operation and reduce the energy consumption of the opening and closing drive mechanism.

[0036] After the pressure holding period, the two battery modules and the heat exchange plate form a whole. At this point, the two side pressure-applying components 2 need to be moved away from each other so that protective covers can be installed on both sides of the whole. Furthermore, the check mechanism 6 can be used to position the two side pressure-applying components 2 to prevent them from getting close to each other, thus avoiding accidental closure of the side pressure-applying components 2 and preventing operator injury, thereby improving safety.

[0037] In some embodiments, the check mechanism 6 includes a check assembly 61 corresponding to the side pressure member 2. The check assembly 61 includes a check mating member 611, a mounting base 612, and a check member 613. The check mating member 611 is fixed to the side pressure member 2; the mounting base 612 is fixed to the base 1; and the check member 613 includes a pin. The pin is adjustablely positioned on the mounting base 612 along a second direction so that the pin can abut or separate from the check mating member 611 along a first direction. The first direction and the second direction are perpendicular to the vertical direction. Exemplarily, the check assembly 61 and the side pressure member 2 are arranged one-to-one. When the side pressure member 2 needs to move along the first direction, the pin moves along the second direction and retracts. In other words, the pin moves along the second direction and away from the check mating member 611, so that the pin will not contact the check mating member 611, thereby not obstructing the movement of the side pressure member 2. When the side pressure member 2 moves to a suitable position (e.g., the position of the side pressure member 2 during pressure holding or when the protective cover is placed), the pin body moves and extends in the second direction. In other words, the pin body moves in the second direction and approaches the check valve 611, thereby allowing the pin body to abut against the check valve 611 in the first direction to prevent the side pressure member 2 from moving in the first direction, thus positioning the side pressure member 2. For example, the check valve 613 is an indexing pin.

[0038] In some embodiments, the check assembly 61 includes multiple check members 613, each including at least two first check members 613a, which are spaced apart along a first direction. This allows one of the first check members 613a to abut against the check engagement member 611 along the first direction during pressure holding, preventing the side pressure applying member 2 from moving away from the other side pressure applying member 2. Furthermore, after pressure holding is completed and the two side pressure applying members 2 are moved away from each other, another first check member 613a abuts against the check engagement member 611 along the first direction, preventing the side pressure applying member 2 from moving closer to the other side pressure applying member 2.

[0039] Specifically, in this embodiment, the side pressure member 2 has a closed position and an open position. In the closed position, the two side pressure members 2 clamp the carrier 3 and the battery module it carries. In the open position, the side pressure members 2 are spaced apart from the adjacent carrier 3, thereby reserving operating space for operators to install protective covers, etc.

[0040] Furthermore, at least two first check valves 613a are respectively provided corresponding to the closed position and the open position; that is, a first check valve 613a is provided in both the closed and open positions. For ease of description, the first check valve 613a in the closed position is referred to as the closed check valve, and the first check valve 613a in the open position is referred to as the open check valve. Specifically, by abutting the closed check valve against the end of the check valve fitting 611 away from the carrier 3 in the first direction, the side pressure member 2 can be positioned in the closed position. By abutting the open check valve against the end of the check valve fitting 611 near the carrier 3 in the first direction, the side pressure member 2 can be positioned in the open position.

[0041] In some embodiments, the check assembly 61 further includes at least two second check elements 613b in addition to the plurality of check elements 613, which are spaced apart in a vertical direction. This allows the first check element 613a and the second check element 613b to simultaneously abut against the check mating member 611 during pressure holding and / or placement of the protective cover. In other words, the first check element 613a and the second check element 613b are redundant, thereby improving the positioning reliability and stability of the side pressure application member 2.

[0042] In some embodiments, the top pressure member 4 and the support member 5 are detachably connected. Thus, when the battery module is placed on the carrier 3, the top pressure member 4 can be removed first, and after the battery module is placed on the carrier 3, the top pressure member 4 can be installed on the support member 5. This can prevent the battery module from bumping into the top pressure member 4, protect the battery module, and improve safety.

[0043] For example, the top pressure member 4 is provided with a slider, and the support member 5 is provided with a groove and a limiting block. The slider is slidably disposed in the groove in the vertical direction, and the limiting block is locked at the top of the support member 5. When it is necessary to disassemble the top support member 5, the limiting block is removed first, and then the top pressure member 4 is slid upward and disengaged from the groove.

[0044] In some embodiments, the top pressure member 4 is slidably disposed on the support member 5 in the vertical direction, which facilitates the adjustment of the position of the top pressure member 4 in the vertical direction by manually or by a lifting drive mechanism, making the operation more convenient.

[0045] It should be noted that the opening and closing drive mechanism and the lifting drive mechanism can adopt existing technologies such as cylinders and linear actuators, which will not be elaborated here.

[0046] In some embodiments, the battery assembly fixture further includes a locking mechanism that can lock or unlock the top pressure member 4 and the support member 5. Specifically, when the top pressure member 4 is pressed against the top of the battery module, the locking mechanism locks the top pressure member 4 and the support member 5 to improve the reliability of the top pressure member 4 and reduce the energy consumption of the lifting drive mechanism.

[0047] In some embodiments, the locking mechanism includes a quick-release clamp 7 mounted on the base 1. The quick-release clamp 7 is capable of clamping or releasing the top pressure member 4. Specifically, the pressure head of the quick-release clamp 7 presses against the top surface of the top pressure member 4, thereby positioning the top pressure member 4. This not only provides convenient operation but also high reliability. It should be noted that the quick-release clamp 7 can be a manual quick-release clamp or a pneumatic quick-release clamp, as is available in the prior art.

[0048] In other embodiments, the locking mechanism may include a locking pin and a locking hole, one of which is located on the top pressure member 4, and the other on the base 1. The locking pin can be inserted into and locked in the locking hole or separated from it. This simplifies the structure of the locking mechanism and reduces costs. For example, the locking pin is threaded into the locking hole, so simply rotating the locking pin locks it in or out of the locking hole, making operation more convenient.

[0049] In some embodiments, the battery assembly fixture further includes an elastic element 8, which elastically supports the top pressure member 4 vertically upward. Therefore, when the pressure exerted on the top pressure member 4 by the lifting drive mechanism disappears, the top pressure member 4 can rise under the elastic force of the elastic element 8 and separate from the battery module, thus protecting the battery module.

[0050] In some embodiments, the carrier 3 is provided with a mounting slot 31 for placing individual battery cells. Placing the individual battery cells in the mounting slot 31 can prevent displacement of the battery cells during the operation of the battery assembly fixture, which helps to improve the quality of battery assembly.

[0051] In some embodiments, the battery cell is a cylindrical battery; the mounting groove 31 includes a bottom wall, which is an arc-shaped surface that matches the outer peripheral surface of the cylindrical battery. This allows the outer peripheral surface of the cylindrical battery to fit tightly against the arc-shaped surface, enabling the cylindrical battery to be placed more stably within the mounting groove 31.

[0052] Specifically, the cylindrical battery is placed horizontally in the mounting groove 31. In other words, the axis of the cylindrical battery is perpendicular to the vertical direction. In this embodiment, the axis of the cylindrical battery is parallel to the first direction. This ensures that the cylindrical battery will not be misaligned when the two side pressure members 2 clamp the battery module, which is beneficial to improving the battery assembly quality.

[0053] In some embodiments, multiple mounting slots 31 are provided, and the multiple mounting slots 31 are arranged along the second direction. Specifically, each mounting slot 31 holds one battery cell, and multiple battery cells can be placed simultaneously through multiple mounting slots 31, so that the battery assembly fixture can be adapted to different models of battery modules and improve the versatility of the battery assembly fixture.

[0054] In some embodiments, the battery assembly fixture further includes a positioning mechanism that can position the heat exchange plate passing through the through slot 41. This prevents displacement of the heat exchange plate when the two side pressure members 2 clamp the battery module, improving the installation position accuracy of the heat exchange plate and further enhancing the battery assembly quality.

[0055] In some embodiments, the positioning mechanism includes at least two positioning blocks, with positioning blocks provided at both ends of the carrier 3 along the second direction, and the positioning blocks being able to support the bottom of the heat exchange plate. This configuration results in a simple structure and helps reduce costs.

[0056] In some embodiments, the positioning block is provided with a positioning groove, and the bottom end of the heat exchange plate can be inserted into the positioning groove. This further improves the positioning effect of the heat exchange plate.

[0057] In some embodiments, the top pressure member 4 is further provided with a relief groove 42, which is used to avoid the clamps holding the heat exchange plate. This facilitates the placement of the heat exchange plate in one go and improves assembly convenience.

[0058] In some embodiments, the side pressure member 2 is provided with a first pad on the side facing the carrier 3, so that when the side pressure member 2 clamps the battery module, the first pad can protect the side of the battery module.

[0059] In some embodiments, the top pressure member 4 is provided with a second pad on the side facing the carrier 3, so that when the top pressure member 4 clamps the battery module, the top of the battery module can be protected by the second pad.

[0060] For example, the working principle of the battery assembly fixture in this embodiment is as follows:

[0061] like Figure 2 As shown, the two side pressure members 2 are moved away from each other in the first direction, and the two carriers 3 are also moved away from each other in the first direction. Then, the pin of the opening check piece is extended so that the pin abuts against the end of the check fit 611 near the carrier 3 in the first direction to prevent the two side pressure members 2 from getting closer to each other.

[0062] Place the two battery modules on the two carriers 3 respectively, and position each battery cell in its corresponding mounting slot 31. Then, pass the heat exchange plate through the through slot 41 and insert it between the two battery modules. Next, retract all the pins of the check valves 613 to cancel the positioning effect on the side pressure member 2.

[0063] The two side pressure members 2 are driven to move closer together by manual operation or an opening / closing drive mechanism. The side pressure members 2 push the carrier 3 closer together, thereby clamping the heat exchange plate between the two battery modules. Then, the top pressure member 4 is driven to descend vertically by manual operation or a lifting drive mechanism, pressing it against the top of the battery modules. Next, the quick clamp 7 clamps the top pressure member 4, and the pin of the closing check valve extends, so that the pin abuts against the end of the check valve 611 away from the carrier 3 in the first direction, thereby positioning the side pressure members 2 in the closed position. Figure 3 As shown, pressure is maintained to bond and fix the two battery modules and the heat exchange plate together.

[0064] After the pressure holding period ends, the pin of the closed check valve is retracted to cancel the positioning effect on the side pressure component 2. For example... Figure 4 As shown, the two side pressure members 2 are then driven away from each other manually or by an opening and closing drive mechanism, causing the pin of the check valve to extend and abut against the end of the check valve fitting 611 near the carrier 3 in the first direction, thus preventing the two side pressure members 2 from getting closer to each other. Then, protective covers are installed on both sides of the integral formed by the two battery modules and the heat exchange plate.

[0065] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
