DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0046] Reference to "an embodiment" or "the embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" or "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily all referring to a particular embodiment logically separated from the other embodiments of the application. As such, the embodiments described herein, in their various aspects or objects, can be combined to provide further embodiments of the application.

[0047] At present, the polar plate processing mode of riveting has the following problems: the cylinder edge is deformed at the bottom during riveting, extruding the internal space of the pole, resulting in product defects; the end face diameter of the polar plate becomes smaller during forming, the thickness of the polar plate changes after being extruded, affecting the installation space of the pole, and the polar plate is mostly made of aluminum material, which is easy to produce metal chips when extruded, so the metal chip removal process needs to be added to remove the generated metal chips, thus increasing the number of polar plate parts and processes, reducing production efficiency and quality stability, and increasing the manufacturing cost of the product.

[0048] The internal space of the pole hole must be supported by adding parts during riveting to ensure the size of the internal space, and the riveting force is large, so the internal support is mostly a non-metal insulating part, which is a brittle material and is easy to be crushed during riveting, forming defective products and affecting the processing efficiency of the polar plate. The sealing ring needs to be extruded first during riveting, and the sealing ring is an elastic part that has the risk of falling off when extruded.

[0049] Therefore, the present embodiment provides a cover plate assembly 100, a battery 200 and an automobile 300, which can reduce the processing difficulty of the top cover of the battery 200 during processing.

[0050] Please refer to Figures 1 to 3 A cover plate assembly 100 comprises:

[0051] A polar plate 10 is provided with a pole hole 12 penetrating through the polar plate 10, and the edge of one side of the pole hole 12 is provided with a support part 11;

[0052] A pole 20 is arranged at the pole hole 12, and the pole 20 is supported by the support part 11;

[0053] A bending part 30 is arranged on the other side of the polar plate 10, the bending part 30 comprises a first bending segment 31 and a second bending segment 32, the first bending segment 31 extends away from the support part 11, the second bending segment 32 extends towards the axis of the pole 20 and abuts against the pole 20, and an arc-shaped bend is formed between the first bending segment 31 and the second bending segment 32.

[0054] The cover plate assembly 100 of the present invention is first riveted to the pole plate 10, and a pole hole 12 is provided on the pole plate 10. A support portion 11 extending into the pole hole 12 is provided on the pole plate 10. The support portion 11 and the side wall of the pole hole 12 form an installation space. The pole 20 is installed in the installation space. The support portion 11 can support the pole 20, and the pole hole 12 can limit the displacement of the pole 20 in the horizontal direction; the bending portion 30 is provided with a first bending section 31 and a second bending section 32, the first bending section 31 extends in the direction away from the supporting section, and the second bending section 32 extends in the direction close to the axis of the pole 20, so that the second bending section 32 can be connected to the pole 20, so that the pole 20 can be restricted in the pole hole 12 by the bending portion 30, so as to fix the pole 20; thereby reducing the deformation of the pole plate 10 around the pole 20 during the riveting process and reducing the processing difficulty of the battery 200 top cover, thereby improving the processing efficiency and processing yield of the battery 200 top cover.

[0055] As can be understood, a pole hole 12 is provided on the pole plate 10, and the pole hole 12 passes through the pole plate 10. A support portion 11 is provided in the pole hole 12, and the support portion 11 is provided around the outer periphery of the pole hole 12. The pole hole 12 is used to install the pole 20, and one end of the pole 20 abuts against the support portion 11. The support portion 11 can support the pole 20. A bending portion 30 is provided on the side of the pole plate 10 away from the support portion 11. The bending portion 30 includes a first bending section 31 and a second bending section 32, wherein the first bending section 31 extends in a direction away from the support portion 11, and the second bending section 32 extends in a direction close to the axis of the pole 20. The second bending section 32 is used to abut against the pole 20, so that the second bending section 32 can limit the displacement of the pole 20 in the horizontal direction.

[0056] It can be understood that the bending portion 30 has a first state and a second state. In the first state, the second bending section 32 cannot fix the pole 20, and the second bending section 32 does not abut against the pole 20, that is, the pole 20 can be installed in the pole hole 12. After the pole 20 is installed in the pole hole 12, the pole plate 10 is riveted. After the riveting is completed, the second bending section 32 is bent to put the bending portion 30 in the second state. The second bending section 32 in the second state abuts against the pole 20, and the second bending section 32 can fix the pole 20. In this way, it is possible to avoid the deformation of the pole 20 caused by fixing the pole 20 to the pole plate 10 during processing, thereby reducing the deformation of the pole plate 10 around the pole 20 and reducing the processing difficulty of the battery 200 top cover, thereby improving the processing efficiency and processing yield of the battery 200 top cover.

[0057] See also Figure 4 and Figure 5In some embodiments, a fixing portion 21 is provided on the outer periphery of the pole 20 , and the fixing portion 21 abuts against the multiple bending portions 30 , and the multiple bending portions 30 cooperate with the fixing portion 21 to limit the movement of the pole 20 .

[0058] It can be understood that a fixing portion 21 is provided on the pole 20, and the fixing portion 21 is provided so as to protrude from the outer periphery of the pole 20, and the protruding portion is provided at the midpoint of the pole 20. The outer diameter of the fixing portion 21 is smaller than the outer diameter of the pole hole 12. In this way, after the pole 20 is installed in the pole hole 12, the fixing portion 21 can also be partially located in the pole hole 12. The fixing portion 21 contacts the side wall of the pole hole 12, which can limit the movement of the pole 20.

[0059] Before riveting the electrode plate 10, the electrode 20 is first installed in the electrode hole 12. After riveting is completed, the second bent section 32 is bent so that the second bent section 32 abuts against the fixing portion 21. In this way, the second bent section 32 can limit the displacement of the electrode 20 in the vertical and horizontal directions, so that the bent portion 30 plays the role of limiting the fixing portion 21, thereby reducing the processing efficiency of the electrode plate 10 during processing.

[0060] See also Figure 2 and Figure 3 In some embodiments, a plurality of the bending portions 30 are arranged at intervals along the outer circumference of the pole hole 12 , and a slot 33 is formed between two adjacent bending portions 30 .

[0061] It can be understood that there are multiple bending portions 30, and the multiple bending portions 30 are spaced apart along the outer periphery of the pole hole 12. The second bending sections 32 of the multiple bending portions 30 all extend toward the axis of the pole hole 12, and the second bending sections 32 of the multiple bending portions 30 all abut against the fixing portion 21. The spacing distance of the bending portions 30 can be determined according to the diameter of the pole 20. When the diameter of the pole 20 is large, the spacing distance can be larger. When the diameter of the pole 20 is small, the spacing distance of the bending portions 30 can be reduced. A slot 33 is formed between two adjacent bending portions 30. The slot 33 can be used to install a baffle or other components that can cover the bending portion 30 to play a role in the bending portion 30.

[0062] It is understandable that the slots 33 formed between the bent portions 30 can also reduce the strength of the bent edges, eliminating the need for support when riveting the electrode plate 10. The riveting bend position can be freely determined, achieving controllable height riveting, and ensuring a gap between the top cover of the electrode plate 10 and the electrode post 20. The slots 33 can also release the stress generated by the electrode plate 10 during riveting, reducing the extrusion on the end face of the cover during molding, and effectively avoiding the generation of metal chips.

[0063] See also Figure 4, in some embodiments, the support portion 11 includes: a first support portion 111 and a second support portion 112;

[0064] The first support portion 111 extends in a direction away from the bending portion 30 , and the second support portion 112 extends in a direction close to the center of the pole hole 12 ; wherein the second support portion 112 is inclined in a direction close to the bending portion 30 .

[0065] As can be understood, the support portion 11 includes a first support portion 111 and a second support portion 112, wherein the first support portion 111 extends in a direction away from the bending portion 30 so that the first support portion 111 can be away from the electrode 10, so that the electrode 20 can have a deeper installation space; the second support portion 112 extends in a direction close to the center of the electrode hole 12, and the second support portion 112 is inclined in a direction close to the bending portion 30. The inclined setting of the second bending portion 30 can make the support portion 11 have stronger strength; the second support portion 112 can also play a buffering role for the electrode 20. Specifically, after the electrode 20 is subjected to force, the force of the electrode 20 can be transmitted to the second support portion 112, and the inclined second support portion 112 can play a buffering role. After receiving the force of the electrode 20, the second support portion 112 deforms in the same direction as the force direction to enhance the structural strength of the support portion 11 and reduce the probability of the electrode 20 damaging the electrode 10 after being subjected to force.

[0066] See also Figure 5 and Figure 6 In some embodiments, a plurality of grooves 211 are provided at intervals on a side of the fixing portion 21 away from the supporting portion 11 .

[0067] It can be understood that grooves 211 are provided on the surface of the fixing portion 21 away from the supporting portion 11, and the grooves 211 are arranged at intervals; Figure 4 As shown, in this embodiment, four grooves 211 are provided, and the four grooves 211 are respectively provided on both sides of the fixing portion 21 in the vertical direction and on both sides in the horizontal direction. The grooves 211 can cooperate with the bending portion 30 so that the grooves 211 play the role of fixing the pole 20. For example, a protrusion is provided on the second bending section 32, and the protrusion cooperates with the groove 211 to achieve the function of fixing the pole 20.

[0068] See also Figure 9 and Figure 10 In some embodiments, the invention further comprises: a cover 60;

[0069] The cover 60 includes a covering portion 61, a plurality of buckle portions 62, and an extending portion 63;

[0070] The extension part 63 is arranged around the inner periphery of the covering part 61, and extends away from the covering part 61. The plurality of buckle parts 62 are arranged at intervals between the covering part 61 and the extension part 63, and are matched with the clamping groove 33.

[0071] It can be understood that the covering part 60 is arranged on the pole 20 to protect the pole 20, and the covering part 60 comprises a covering part 61, a buckle part 62, and an extension part 63. The extension part 63 is arranged around the inner periphery of the covering part 61, and extends away from the covering part 61, i.e. extends downward as shown. Figure 11 The extension part 63 is used to fill the gap between the bent part 30 and the pole 20, so as to avoid sundries from entering the pole hole 12 and corroding the pole 20 or the polar plate 10, and affecting the normal use of the pole 20 or the polar plate 10.

[0072] It can be understood that the buckle part 62 is arranged between the extension part 63 and the covering part 61, and a plurality of buckle parts 62 are arranged at intervals between the extension part 63 and the covering part 61. When the covering part 60 is installed, the buckle part 62 is clamped into the groove 211, so that the buckle part 62 is matched with the groove 211. At this time, the covering part 61 covers the bent part 30, and the covering part 61 protects the bent part 30. The covering part 60 is fixed to the mounting part, so that the upper surface of the polar plate 10 is a relatively flat plane, and the covering part 60 can also protect the pole 20 and the mounting part.

[0073] Please refer to Figure 7 and Figure 8 In some embodiments, the plastic part 40 is further included.

[0074] The plastic part 40 is arranged around the outer periphery of the fixing part 21. One side of the plastic part 40 abuts against the pole 20, and the other side of the plastic part 40 abuts against the side wall of the pole hole 12. The plastic part 40 is used to limit the circumferential displacement of the pole 20.

[0075] It can be understood that the shape of the plastic part 40 is matched with the shape of the pole 20. The plastic part 40 is arranged between the pole hole 12 and the pole 20. The outer periphery of the plastic part 40 abuts against the pole hole 12, and the inner periphery of the plastic part 40 abuts against the pole 20. Thus, the pole 20 is surrounded by the plastic part 40, so as to limit the shaking of the pole 20, and fix the pole 20, thereby avoiding the circumferential displacement of the pole 20. The plastic part 40 can also fill the gap between the pole hole 12 and the pole 20, and avoid sundries from entering the pole hole 12, thereby affecting the normal use of the pole 20 or the polar plate 10.

[0076] Please refer to Figure 7 and Figure 8 In some embodiments, the plastic member 40 is provided with a limiting portion 41, a recessed portion 42 and a plurality of clamping portions 43;

[0077] The limiting portion 41 is protruding from the inner circumference of the plastic part 40, the recessed portion 42 is arranged below the plastic part 40, and a plurality of the clamping portions 43 are arranged at intervals on the inner circumference of the plastic part 40. The clamping portions 43 are located in the recessed portion 42, and the clamping portions 43 are used to cooperate with the groove 211.

[0078] It can be understood that the plastic part 40 includes a limiting portion 41, a recessed portion 42 and a clamping portion 43. The limiting portion 41 protrudes from the inner circumference of the plastic part 40 and extends in a direction close to the center of the circle. The limiting portion 41 is used to be clamped to the top of the fixing portion 21, and the inner diameter of the limiting portion 41 is adapted to the outer diameter of the pole 20, so that the pole 20 can be inserted into the limiting portion 41. After the pole 20 is inserted into the limiting portion 41, the abutment between the fixing portion 21 and the limiting portion 41 can also limit the displacement of the pole 20 in the vertical direction.

[0079] It can be understood that the recessed portion 42 is provided below the plastic member 40, and the inner diameter of the recessed portion 42 is adapted to the outer diameter of the fixing portion 21. When the plastic member 40 is installed in the pole hole 12, the outer periphery of the fixing portion 21 abuts against the recessed portion 42, so that the pole 20 can be better fixed and limited. At the same time, the structure below the recessed portion 42 is adapted to the structure of the pole 20, so that there is no gap between the pole hole 12 and the pole 20, so that the pole 20 has a better fixing effect.

[0080] It can be understood that the clamping portions 43 are arranged at intervals on the inner circumference of the plastic part 40, and the clamping portions 43 are used to cooperate with the grooves 211. Specifically, a plurality of clamping portions 43 are provided, and the number of the clamping portions 43 is the same as the number of the grooves 211. After the plastic part 40 is installed in the pole hole 12, the clamping portions 43 can cooperate with the grooves 211, further cooperating the plastic part 40 and the pole 20, and further improving the stability of the cover plate assembly 100.

[0081] See also Figure 11 , in some embodiments, a seal 50;

[0082] The sealing member 50 is sandwiched between the supporting portion 11 and the fixing portion 21 , and is used to seal the gap between the supporting portion 11 and the pole 20 .

[0083] It can be understood that the second support portion 112 is configured to be inclined in the direction close to the bending portion 30, so that after the sealing ring is placed on the second support portion 112, the outer periphery of the second support portion 112 can be inserted into the inner periphery of the sealing ring, so that the second support portion 112 plays a positioning role for the sealing ring, and when the seal 50 is squeezed, it can prevent the seal 50 from falling, so as to further improve the yield rate and processing efficiency during processing.

[0084] The cover plate in the present invention is first riveted to the electrode plate 10 and then the electrode 20 is installed. Before riveting, the electrode 20 can be installed in the electrode hole 12 first, but the second bent section 32 is not bent, so that the electrode 20 is in an active state in the electrode hole 12. Therefore, the electrode 20 does not affect the riveting of the electrode plate 10. After the riveting of the electrode plate 10 is completed, the second bent section 32 is bent so that the second bent section 32 abuts against the fixing portion 21, so that the fixation of the electrode 20 can be completed. The plastic part 40 can be formed by pouring resin, plastic or other materials into the electrode hole 12 after the electrode 20 is fixed. In this way, the deformation of the electrode plate 10 around the electrode 20 during the riveting process and the processing difficulty of the battery 200 top cover can be reduced, thereby improving the processing efficiency and processing yield of the battery 200 top cover.
