[0037] The above-mentioned isolation plate structure, since the column part is passed through the installation through hole and is slidably connected with the busbar plate body, the column part can realize pre-fixation of the busbar plate body, the buckle part abuts against the busbar plate body, and the busbar plate body is located below the buckle part, so that the buckle part clamps the busbar plate body in the receiving groove, so that the column part and the buckle part work together to assemble and fasten the busbar plate body in the receiving groove, thereby avoiding the problem of the prior art that the assembly between the isolation plate main body and the busbar plate body is a circular hole gap fit, thereby solving the problem of the prior art that the isolation plate main body is a circular hole gap fit, The body and the busbar plate body are fixedly connected by hot riveting through the column part and the mounting through-hole, that is, the problem that the isolation plate structure in the prior art needs to add a hot riveting process to achieve a fastening connection between the isolation plate body and the busbar plate body, so that the isolation plate structure can achieve a fastening connection between the isolation plate body and the busbar plate body through the joint action of the column part and the snap part, so that the isolation plate structure does not need to be processed by the hot riveting process, and at the same time simplifies the manufacturing process steps of the isolation plate structure, thereby making the manufacturing cost of the isolation plate structure lower.

[0038] In order to better understand the technical solutions and beneficial effects of the present invention, the present invention is further described in detail below in conjunction with specific embodiments:

[0039] like Figures 1 to 3As shown, an isolation plate structure 10 of an embodiment includes an isolation plate body 100 and a busbar plate body 200, the busbar plate body 200 is provided with a mounting through hole 210, the isolation plate body 100 is provided with a receiving groove 110, the busbar plate body 200 is located in the receiving groove 110, the mounting through hole 210 is communicated with the receiving groove 110, the inner bottom wall of the receiving groove 110 is provided with a column portion 111, the column portion 111 is passed through the mounting through hole 210 and is slidably connected to the busbar plate body 200; the inner side wall of the receiving groove 110 is provided with a snap portion 112, the snap portion 112 is in contact with the busbar plate body 200, and the busbar plate body 200 is located below the snap portion 112, so that the snap portion 112 snaps the busbar plate body 200 into the receiving groove 110.

[0040] In this embodiment, the column portion 111 is inserted into the mounting hole 210 and is slidably connected to the busbar plate 200, so that the column portion 111 can pre-fix the busbar plate 200. The buckle portion 112 abuts against the busbar plate 200, and the busbar plate 200 is located below the buckle portion 112, so that the buckle portion 112 can clamp the busbar plate 200 in the receiving groove 110, so that the busbar plate 200 is located in the receiving groove 110 and has an interference fit with the buckle portion 112.

[0041] The above-mentioned isolation plate structure 10, since the column part 111 is penetrated through the installation hole 210 and is slidably connected with the busbar plate body 200, so that the column part 111 can realize the pre-fixation of the busbar plate body 200, the buckle part 112 is in contact with the busbar plate body 200, and the busbar plate body 200 is located below the buckle part 112, so that the buckle part 112 can clamp the busbar plate body 200 in the receiving groove 110, so that the column part 111 and the buckle part 112 work together to assemble and fasten the busbar plate body 200 in the receiving groove 110, thereby avoiding the problem of the prior art that the isolation plate main body 100 and the busbar plate body 200 are assembled as a circular hole gap fit, thereby solving the problem of the prior art. The problem of the isolation plate body 100 and the busbar plate body 200 being fixedly connected by hot riveting between the column part 111 and the mounting through-hole 210 in the prior art is solved, that is, the problem that the isolation plate structure 10 in the prior art needs to add a hot riveting process to achieve the fastening connection between the isolation plate body 100 and the busbar plate body 200, so that the isolation plate structure 10 achieves the fastening connection between the isolation plate body 100 and the busbar plate body 200 through the joint action of the column part 111 and the snap part 112, so that the isolation plate structure 10 does not need to be subjected to the hot riveting process, and at the same time simplifies the manufacturing process steps of the isolation plate structure 10, thereby making the manufacturing cost of the isolation plate structure 10 lower.

[0042] In one embodiment, the isolation plate body 100, the column portion 111 and the snap portion 112 are an integrally formed structure, so that the structural strength between the isolation plate body 100, the column portion 111 and the snap portion 112 is higher, thereby making the isolation plate structure 10 have better structural stability.

[0043] like Figures 2 to 3 As shown, in one embodiment, the buckle portion 112 is provided with a holding bevel 1121, and the holding bevel 1121 abuts against the busbar plate body 200. In this embodiment, the holding bevel 1121 is inclined relative to the inner wall of the receiving groove 110, and the holding bevel 1121 abuts against the side end top edge of the busbar plate body 200, so that the holding bevel 1121 can press the busbar plate body 200, that is, during the assembly process of the busbar plate body 200, the side end top edge of the busbar plate body 200 slides along the holding bevel 1121 toward the inner wall of the receiving groove 110 to a predetermined position for pressing, so that the column portion 111 and the buckle portion 112 work together to assemble and fasten the busbar plate body 200 in the receiving groove 110, thereby making the manufacturing cost of the isolation plate structure 10 relatively low.

[0044] like Figure 1 to Figure 2 As shown, in one embodiment, the mounting hole 210 is a waist-shaped hole. In this embodiment, the cross section of the mounting hole 210 is in the shape of an elongated strip, so that the column portion 111 can slide in the mounting hole 210, and is used to fine-tune the position of the busbar plate body 200 in the receiving groove 110, so that the position of the busbar plate body 200 in the receiving groove 110 is more flexible.

[0045] Furthermore, if Figure 1 to Figure 2 As shown, in one embodiment, the busbar plate body 200 is further provided with a positioning through hole 220 , the positioning through hole 220 is spaced apart from the mounting through hole 210 , and the positioning through hole 220 is communicated with the receiving groove 110 . In the present embodiment, the positioning through hole 220 is used to cooperate with the battery cell pole, that is, the battery cell pole is passed through the positioning through hole 220 and connected to the busbar plate 200; in the related art, the assembly between the isolation plate main body 100 and the busbar plate 200 is a circular hole gap fit, resulting in the busbar plate 200 being unable to move left and right in the receiving groove 110 to fine-tune the position after assembly is completed, and there is a certain assembly tolerance between two adjacent battery cells in the battery module, so that the positioning accuracy between the battery cell pole and the positioning through hole 220 of the busbar plate 200 in the battery module is poor. Therefore, when the mounting hole 210 is a waist-shaped hole, the column portion 111 can slide in the mounting through hole 210, so that the busbar plate 200 can move left and right in the receiving groove 110 to fine-tune the position after assembly is completed, so that the positioning accuracy between the battery cell pole and the positioning through hole 220 of the busbar plate 200 in the battery module is better.

[0046] like Figure 2 As shown, in one of the embodiments, the inner wall of the accommodating groove 110 is provided with an avoidance groove 113, and the avoidance groove 113 is correspondingly connected with the positioning through hole 220, so that the battery cell pole passes through the avoidance groove 113 and is arranged in the positioning through hole 220, so that the connection between the battery cell pole and the busbar plate body 200 is more convenient.

[0047] like Figure 1 to Figure 2 As shown, in one embodiment, the isolation plate body 100 is further provided with a pick-up slot 120, which is connected to the receiving slot 110. In this embodiment, the pick-up slot 120 is located on the side of the isolation plate body 100 away from the buckle portion 112, so that part of the side wall of the busbar plate body 200 is exposed, so as to facilitate the staff to take and place, so that the busbar plate body 200 is more convenient to take and place.

[0048] In one embodiment, the isolation plate body 100 is an elastic plate structure. In this embodiment, the isolation plate body 100 is a polycarbonate structure, so that the isolation plate body 100 has elasticity, so that the isolation plate body 100 can be well interference-fitted with the busbar plate body 200 under the joint action of the column part 111 and the buckle part 112, so that the busbar plate body 200 is assembled and fastened in the receiving groove 110, so that the manufacturing cost of the isolation plate structure 10 is low.

[0049] like Figure 1 to Figure 2 As shown, in one embodiment, the mounting hole 210 is elastically interference-connected with the column portion 111 , so that the connection between the column portion 111 and the mounting hole 210 is more convenient.

[0050] Furthermore, if Figure 1 to Figure 2 As shown, in one embodiment, the number of the column parts 111 and the number of the mounting holes 210 are both two, the two mounting holes 210 are arranged at intervals, the two column parts 111 and the two mounting holes 210 are arranged one-to-one correspondingly, and the pick-up and placement notch 120 is located between the two column parts 111. In this embodiment, the pick-up and placement notch 120 is located between the two column parts 111, that is, the pick-up and placement notch 120 exposes the middle section side wall of the busbar plate 200, so that the staff can better apply the force on the busbar plate 200 during the pick-up and placement process, further improving the pick-up and placement convenience of the busbar plate 200.

[0051] Furthermore, in one embodiment, there are two snap-fit ​​portions 112 , which are spaced apart from each other. Each snap-fit ​​portion 112 snaps the busbar plate 200 into the receiving groove 110 , further improving the position stability of the busbar plate 200 in the receiving groove 110 .

[0052] Furthermore, in the related art, the height of the column part 111 of the isolation plate body 100 needs to be designed according to the thickness of the bus bar plate body 200, so that there is enough glue during thermal riveting to fasten the bus bar plate body 200. As a result, the height of the column part 111 needs to be proportional to the thickness of the bus bar plate body 200. After the mold is opened, the bus bar plate body 200 cannot be changed, making the structure of the bus bar plate body 200 single and fixed, resulting in the isolation plate body 100 being unable to meet the bus bar plate bodies 200 of other thicknesses, and thus the adaptability of the isolation plate body 100 is poor. As Figure 1 to Figure 2 shown, in one embodiment, the height of the column part 111 is less than or equal to the depth of the receiving groove 110, so that the column part 111 is located within the receiving groove 110. The column part 111 and the buckle part 112 jointly act to assemble and fasten the bus bar plate body 200 within the receiving groove 110, solving the problem in the prior art that the isolation plate structure 10 needs to add a thermal riveting process to achieve the fastening connection between the isolation plate body 100 and the bus bar plate body 200. The isolation plate structure 10 realizes the fastening connection between the isolation plate body 100 and the bus bar plate body 200 through the joint action of the column part 111 and the buckle part 112, so that the isolation plate structure 10 does not need to be processed by the thermal riveting process. Therefore, the height of the column part 111 of the isolation plate body 100 does not need to be designed according to the thickness of the bus bar plate body 200, enabling the isolation plate body 100 to adapt to bus bar plate bodies 200 of different thicknesses, and thus the adaptability of the isolation plate body 100 is better.

[0053] Furthermore, in one embodiment, the height of the column part 111 is greater than the depth of the receiving groove 110 and less than or equal to twice the depth of the receiving groove 110. The height of the column part 111 is n, and the depth of the receiving groove 110 is m, that is, m < n ≤ 2m. In this embodiment, two isolation plate structures 10 can be packed and stored in an interleaved manner. The column part 111 of one isolation plate structure 10 is received within the receiving groove 110 of another isolation plate structure 10, and the column part 111 of one isolation plate structure 10 is arranged错开 from the column part 111 of another isolation plate structure 10, avoiding the interference problem during the storage of the two isolation plate structures 10, and making the storage convenience of the isolation plate structure 10 better.

[0054] Furthermore, as Figure 1 to Figure 2 shown, in one embodiment, the column part 111 is slidably clamped with the bus bar plate body 200, so that an interference fit is formed between the column part 111 and the bus bar plate body 200, thereby fixing the position of the bus bar plate body 200 by the column part 111, and further solving the problem in the prior art that the column part 111 is prone to rib pulling when thermally riveted, resulting in poor production of the isolation plate structure 10. Thus, the defect rate of the isolation plate structure 10 is reduced, and further the manufacturing cost of the isolation plate structure 10 is lowered.

[0055] Furthermore, in one embodiment, the busbar plate 200 is interference-fitted with the column portion 111 and the buckle portion 112 respectively. In this embodiment, the busbar plate 200 is assembled with the snap portion 112 and the column portion 111 by interference fit, and the snap portion 112 generates a first extrusion force on the busbar plate 200, and the direction of the first extrusion force is colinear with the normal of the holding inclined surface 1121 of the snap portion 112 and points to the busbar plate 200. At the same time, the column portion 111 will be subjected to a second extrusion force, and the direction of the second extrusion force is perpendicular to the assembly fitting column surface. The busbar plate 200 is tightly fixed in position by the combined action of the first extrusion force and the second extrusion force; and the contact surface between the snap portion 112 and the busbar plate 200 will be recessed inwardly due to the action of the first extrusion force, and the contact surface between the column portion 111 and the busbar plate 200 will be recessed inwardly due to the action of the second extrusion force, which further strengthens the bite effect between the isolation plate body 100 and the busbar plate 200, thereby improving the fastening effect between the isolation plate body 100 and the busbar plate 200.

[0056] like Figures 1 to 4 As shown, the present disclosure also provides a method for manufacturing an isolation plate structure, which is used to manufacture the isolation plate structure 10 of any of the above embodiments. Further, the method for manufacturing the isolation plate structure includes some or all of the following steps:

[0057] S901, obtaining a substrate.

[0058] In this embodiment, the sheet material is a polycarbonate structural sheet material, that is, the sheet material is a thermoplastic plastic sheet material, and the sheet material is subjected to a cutting process to cut the sheet material into substrates of a predetermined size.

[0059] S903, fixing the substrate in a positioning area of ​​a molding device.

[0060] In this embodiment, the molding device is provided with a molding cavity, the positioning area is located in the molding cavity, and the substrate is placed in the positioning area and fixedly connected to the molding device.

[0061] S905, performing a heating process on the substrate by means of a heating mechanism of the forming device.

[0062] In this embodiment, the substrate is heated by a heating mechanism of the molding device to soften the substrate.

[0063] S907, performing a vacuum process on the heated substrate.

[0064] In this embodiment, the molding device is further provided with an exhaust channel and a vacuum channel, and the exhaust channel is respectively connected to the molding cavity and the vacuum channel. A vacuum pump is used to perform vacuum treatment on the heated substrate, that is, the exhaust end of the vacuum pump is connected to the vacuum channel. When the vacuum pump starts to work, an air pressure difference is formed between the exhaust end and the substrate, so that the gas flows along the molding cavity, the exhaust channel and the vacuum channel to the exhaust end. The vacuum pump extracts the gas in the molding cavity, so that the softened substrate is deformed by the air pressure difference and is adhered to the specific contour surface of the molding cavity to form a substrate of a specific shape.

[0065] S909, cooling and separating the vacuumed substrate to obtain a semi-finished isolation plate body.

[0066] In this embodiment, the vacuumed substrate is cooled and separated so that the substrate is separated from the inner wall of the molding cavity to obtain a semi-finished isolation plate body.

[0067] S911, trimming the semi-finished isolation plate body to obtain the isolation plate body 100.

[0068] In this embodiment, the semi-finished isolation plate body is trimmed to remove the plate edges and burrs to obtain the isolation plate body 100.

[0069] S913, fixing the isolation plate body 100 to a tooling fixture.

[0070] In this embodiment, the isolation plate body 100 is fixed to a tooling fixture so that the isolation plate body 100 is fixed, so as to facilitate the subsequent assembly of the busbar plate body 200 .

[0071] S915 , assembling the busbar plate body 200 and the isolation plate body 100 to obtain the isolation plate structure 10 .

[0072] In this embodiment, the busbar plate body 200 and the isolation plate body 100 are assembled so that the isolation plate structure 10 is fastened to the isolation plate body 100 through the joint action of the column part 111 and the snap part 112 to obtain the isolation plate structure 10.

[0073] The above-mentioned isolation plate structure manufacturing method firstly heats the fixed substrate to soften the substrate; then, vacuumizes the heated substrate so that the softened substrate is deformed by the air pressure difference and adhered to the specific contour surface of the molding cavity to form a substrate of a specific shape; then, cools and separates the vacuumized substrate so that the substrate is separated from the inner wall of the molding cavity to obtain a semi-finished isolation plate body; then, repairs the semi-finished isolation plate body. The isolation plate body 100 is obtained by processing the edges to remove the plate edges and burrs. The isolation plate body 100 is provided with a column portion 111 and a buckle portion 112. The column portion 111 is penetrated through the mounting hole 210 and is slidably connected with the busbar plate body 200, so that the column portion 111 can realize the pre-fixation of the busbar plate body 200. The buckle portion 112 abuts against the busbar plate body 200. The busbar plate body 200 is located below the buckle portion 112, so that the buckle portion 112 can clamp the busbar plate body 200. In the receiving groove 110, the column portion 111 and the snap portion 112 work together to assemble and fasten the busbar plate body 200 in the receiving groove 110, thereby avoiding the problem of the prior art that the isolation plate body 100 and the busbar plate body 200 are assembled as a circular hole gap fit, and further solving the problem of the prior art that the isolation plate body 100 and the busbar plate body 200 are fixedly connected by hot riveting with the column portion 111 and the mounting through hole 210, that is, solving the problem that the isolation plate structure 10 in the prior art needs to add a hot riveting process to achieve the fastening connection between the isolation plate body 100 and the busbar plate body 200, so that the isolation plate structure 10 achieves the fastening connection between the isolation plate body 100 and the busbar plate body 200 through the joint action of the column portion 111 and the snap portion 112, so that the isolation plate structure 10 does not need to be subjected to the hot riveting process, and at the same time simplifies the manufacturing process steps of the isolation plate structure 10, thereby making the manufacturing cost of the isolation plate structure 10 lower.

[0074] Furthermore, in one of the embodiments, the step of cooling and separating the substrate after vacuuming includes: first, cooling the substrate so that the substrate of a specific shape is cooled and formed in the molding cavity, so that the substrate of the specific shape is hardened and formed, thereby making the structural stability of the substrate better; then, separating the cooled substrate, blowing the substrate in the molding cavity through the vacuum channel and the exhaust channel, so that the substrate is separated from the inner wall of the molding cavity under the action of the gas, so that the separation of the substrate is more convenient.

[0075] Furthermore, in one of the embodiments, the step of trimming the semi-finished isolation board body includes: first, trimming the semi-finished isolation board body to remove excess board edges so that the performance of the semi-finished isolation board body is better; then, grinding the trimmed semi-finished isolation board body to remove burrs on the semi-finished isolation board body and improve the product quality of the isolation board structure 10.

[0076] Furthermore, in one of the embodiments, after the step of performing a vacuum treatment on the heated substrate and before the step of performing a cooling and separation treatment on the vacuumized substrate, the isolation plate structure manufacturing method further includes: performing a vacuum molding treatment on the substrate.

[0077] In this embodiment, due to the pressure difference between the substrate and the exhaust end, only one side of the heat-softened substrate is in contact with the inner wall of the molding cavity, so that the surface of the substrate in contact with the inner wall of the molding cavity has a surface contour that is exactly the same as that of the molding device, completing the molding of a specific shape of the substrate, making the molding of the substrate more convenient.

[0078] Furthermore, in one of the embodiments, the step of performing plastic molding treatment on the substrate includes: first, performing plastic molding treatment on the column portion 111. As the height of the column portion 111 increases, the defective rate of the column portion 111 increases, and the isolation plate structure manufacturing method greatly reduces the requirement for the height of the column portion 111 for fixing the busbar plate body 200, fundamentally avoiding the problem of defective isolation plate structure 10 due to the irregular shape of the column portion 111, so that the production yield of the isolation plate structure 10 is higher; thereafter, performing plastic molding treatment on the buckle portion 112, so that the buckle portion 112 has better fastening performance to the busbar plate body 200.

[0079] Furthermore, in one of the embodiments, the step of fixing the isolation plate body 100 to a jig includes: first, obtaining a jig having installation and fixing parts for the isolation plate body 100 and the busbar plate body 200; then, fixing the isolation plate body 100 to the jig so that the isolation plate body 100 is fixed to facilitate the subsequent assembly of the busbar plate body 200; then, inspecting the isolation plate body 100 to check whether the assembly between the predetermined jig and the isolation plate body 100 meets the requirements, thereby ensuring that the isolation plate body 100 and the busbar plate body 200 can be assembled normally, so that the isolation plate structure 10 is easier to assemble.

[0080] Furthermore, in one of the embodiments, the step of assembling the busbar plate body 200 and the isolation plate body 100 is specifically as follows: using a suction cup gripper to assemble the busbar plate body 200 and the isolation plate body 100. In this embodiment, the busbar plate body 200 is assembled to the isolation plate body 100 pre-installed on the fixture by using a suction cup gripper, then the suction cup gripper is released and returned to its original position, and then a soft pressing head is used to press down and tighten the busbar plate body 200, so that the busbar plate body 200 and the isolation plate body 100 are buckled and bitten, and the pressing process requires the production cycle to be controlled within 3 seconds, so that the isolation plate structure 10 is more convenient to manufacture; moreover, the soft pressing head can avoid crushing the busbar plate body 200, so that the soft pressing head has better protection performance for the busbar plate body 200.

[0081] Compared with the prior art, the present invention has at least the following advantages:

[0082] Since the column part 111 is passed through the installation hole 210 and is slidably connected with the busbar plate body 200, the column part 111 can realize the pre-fixation of the busbar plate body 200, the buckle part 112 is in contact with the busbar plate body 200, and the busbar plate body 200 is located below the buckle part 112, so that the buckle part 112 can clamp the busbar plate body 200 in the receiving groove 110, so that the column part 111 and the buckle part 112 work together to assemble and fasten the busbar plate body 200 in the receiving groove 110, thereby avoiding the problem of the assembly between the isolation plate main body 100 and the busbar plate body 200 in the prior art as a round hole gap fit, thereby solving the problem of the isolation plate main body 100 and the busbar plate body 200 in the prior art. The isolation plate body 100 and the busbar plate body 200 are fixedly connected by hot riveting through the column part 111 and the mounting through hole 210, which solves the problem in the prior art that the isolation plate structure 10 needs to add a hot riveting process to achieve the fastening connection between the isolation plate body 100 and the busbar plate body 200. The isolation plate structure 10 achieves the fastening connection between the isolation plate body 100 and the busbar plate body 200 through the joint action of the column part 111 and the snap part 112, so that the isolation plate structure 10 does not need to be subjected to the hot riveting process, and at the same time simplifies the manufacturing process steps of the isolation plate structure 10, thereby making the manufacturing cost of the isolation plate structure 10 lower.
