[0001] This application relates to the field of power battery technology, and in particular to a battery pack cover, a battery pack, and a vehicle. Background Technology

[0002] In the battery pack, the battery cells are housed within a frame, and a top cover is mounted on the frame to encapsulate the battery cells. A sealing gasket is provided between the edge of the top cover and the side plate of the frame, and the two are connected by fastening structures such as bolts and rivet nuts.

[0003] In existing technologies, pressure strips are typically installed at the edges of the cover to enhance its structural strength and improve the stability of the connection between the cover and the frame. Simultaneously, the pressure strips also prevent localized warping of the cover's edges, resulting in a better fit between the cover's edges and the frame's side panels, thus improving the sealing performance of the gasket.

[0004] However, in the above structure, adding a pressure strip will increase the overall weight of the battery pack and increase the manufacturing cost. Utility Model Content

[0045] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0047] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0048] As mentioned in the background section, in the prior art, pressure strips are typically installed at the edges of the cover to enhance its structural strength and improve the stability of the connection between the cover and the frame. Simultaneously, the pressure strips also prevent localized warping of the cover's edges, resulting in a better fit between the cover's edges and the side panels of the frame, thus improving the sealing performance of the gasket.

[0049] However, in the above structure, adding a pressure strip will increase the overall weight of the battery pack and increase the manufacturing cost.

[0050] To address the aforementioned problems in the prior art, this utility model provides a battery pack cover, a battery pack, and a vehicle. The battery pack cover includes a cover body and a connecting portion. The connecting portion surrounds the periphery of the cover body. At least one fixing hole is provided on the connecting portion for connection with the battery pack frame. The edge of the connecting portion is provided with a folded edge, and at least one reinforcing portion is provided on the connecting portion. This improves the structural strength of the connecting portion and reduces the possibility of airtightness failure between the battery pack cover and the frame due to local deformation and warping of the connecting portion. Therefore, when the battery pack cover is connected to the frame, the structural strength of the connecting portion can be improved without the use of a pressure strip, and local deformation and warping of the connecting portion can be avoided to improve the sealing performance between the battery pack cover and the frame, thereby reducing the overall weight of the battery pack and lowering manufacturing costs.

[0051] The following describes exemplary application scenarios of this utility model.

[0052] The battery pack cover provided by this utility model can be applied to battery packs in new energy vehicles, such as battery packs for pure electric vehicles and battery packs for plug-in hybrid vehicles. Specifically, the battery pack cover provided by this utility model can improve the structural strength of the connection part without the need for pressure strips, and can prevent local deformation and warping of the connection part to improve the sealing performance between the battery pack cover and the frame, thereby reducing the overall weight of the battery pack and lowering manufacturing costs.

[0053] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0054] Reference Figures 1 to 6 As shown, the battery pack cover 100 provided in this application includes a cover body 110 and a connecting part 120.

[0055] The connecting part 120 surrounds the periphery of the upper cover body 110.

[0056] The connecting part 120 is provided with at least one fixing hole 130 for connecting with the frame 200 of the battery pack.

[0057] The connecting part 120 has a folded edge 140 on the side away from the upper cover body 110, and at least one reinforcing part 150 is provided on the connecting part 120.

[0058] It is understood that the battery pack cover 100 provided in this application can be used in a battery pack, and the battery cells in the battery pack can be installed inside the frame 200. The frame 200 includes a bottom protective plate 210 and a plurality of side plates 220 surrounding the bottom protective plate 210. The connecting part 120 is used to connect with each side plate 220, and the connecting part 120 can be fixed to the side plate 220 through the fixing holes 130 on the connecting part 120 by fasteners such as bolts and rivet nuts, so as to realize the connection between the battery pack cover 100 and the frame 200.

[0059] Reference Figure 2 and Figure 4 As shown, the edge of the connecting part 120 is provided with a folded edge 140, and a reinforcing part 150 is provided on the connecting part 120. This can improve the structural strength of the connecting part 120 and reduce the possibility of local deformation and warping of the connecting part 120 due to its own deformation, which could cause airtightness failure between the battery pack cover 100 and the frame 200. Therefore, when the battery pack cover 100 and the frame 200 are connected, the structural strength of the connecting part 120 can still be improved without the use of a pressure strip, and local deformation and warping of the connecting part 120 can be avoided to improve the sealing performance between the battery pack cover 100 and the frame 200, thereby reducing the overall weight of the battery pack and reducing manufacturing costs.

[0060] For example, at least one reinforcing part 150 may be provided. The number of reinforcing parts 150 may be one, which extends along the extending direction of the connecting part 120 to increase the contact area with the connecting part 120 and improve the structural strength of the connecting part 120. The number of reinforcing parts 150 may also be multiple, and multiple reinforcing parts 150 may be arranged at intervals in the extending direction of the connecting part 120, which can also achieve the above-mentioned effect. The embodiments of this application do not impose too many limitations on this.

[0061] In some embodiments, refer to Figure 2 , Figure 5 and Figure 6 As shown, the connecting part 120 has a first side 121 and a second side 122 facing each other, with the first side 121 facing the frame 200.

[0062] The reinforcing part 150 is a raised rib provided on the connecting part 120.

[0063] In the above embodiment, the connecting part 120 abuts against the side plate 220 of the frame 200 through the first side 121, and the reinforcing part 150 is a rib protruding away from the first side 121, so that the connecting part 120 can fit tightly with the sealing gasket, and avoid the interference of the reinforcing part 150, which would cause an increased gap between the connecting part 120 and the sealing gasket, thereby affecting the sealing effect.

[0064] The reinforcing part 150 is a raised rib that protrudes toward the side opposite to the first side 121, so as to improve the structural strength of the connecting part 120.

[0065] For example, the connecting part 120 and the reinforcing part 150 of the rib structure can be integrally formed by stamping, so that the reinforcing part 150 and the connecting part 120 have high connection strength, the reinforcing part 150 is not easy to fall off the connecting part 120, and it is convenient to process and manufacture.

[0066] In some embodiments, refer to Figures 1 to 4 As shown, there are multiple fixing holes 130, and each fixing hole 130 is arranged at intervals along the extension direction of the connecting part 120.

[0067] There are multiple reinforcing parts 150, and a reinforcing part 150 is provided between two adjacent fixing holes 130.

[0068] In the above embodiment, there are multiple fixing holes 130, and the side plate 220 of the frame 200 can also be provided with the same number of mounting holes. During installation, each fixing hole 130 corresponds to each mounting hole, and fasteners such as bolts and rivet nuts are inserted into the fixing holes 130 and mounting holes in sequence to connect the connecting part 120 and the side plate 220.

[0069] By providing a reinforcing part 150 between two adjacent fixing holes 130, the strength of the partial connecting part 120 at each fixing hole 130 is further enhanced, so as to reduce the local deformation and lifting of the partial connecting part 120 at the fixing hole 130 when the fastener presses the connecting part 120.

[0070] In some embodiments, refer to Figures 1 to 4 As shown, the reinforcing part 150 is elongated and extends along the extending direction of the connecting part 120.

[0071] In the above embodiment, the reinforcing part 150 is an elongated strip extending along the extending direction of the connecting part 120, which can increase the contact area with the connecting part 120 and improve the structural strength of the connecting part 120.

[0072] Among them, reference Figure 2 and Figure 4 As shown, at the bend and turn of the connecting part 120, the reinforcing part 150 is shaped as a bent strip to enhance the structural strength of a portion of the connecting part 120 at the bend and turn.

[0073] Specifically, refer to Figures 1 to 4 As shown, each reinforcing part 150 is spaced apart from each fixing hole 130 so that the reinforcing part 150 avoids the fixing hole 130, and at the same time, it can also reduce manufacturing costs.

[0074] Furthermore, refer to Figure 3 and Figure 4 As shown, the connecting portion 120 has a reinforced region 123 and an effective sealing region 124 that are spaced apart. Both the reinforced region 123 and the effective sealing region 124 extend along the extending direction of the connecting portion 120, and the effective sealing region 124 is close to the upper cover body 110. Each reinforced portion 150 and each fixing hole 130 are located on the reinforced region 123.

[0075] In the above structure, when the sealing gasket is placed between the connecting part 120 and the side plate 220 of the frame 200, the fastener connects the connecting part 120, the sealing gasket and the side plate 220 together through the fixing hole 130.

[0076] By providing both the reinforcing part 150 and the fixing hole 130 on the reinforcing area 123 and separating them from the effective sealing area 124, interference from the reinforcing part 150, fasteners provided in the fixing hole 130, etc., on the effective sealing area 124 can be tightly fitted with the sealing gasket, thereby improving the sealing effect.

[0077] The width of the effective sealing area 124 can be 6mm to 10mm.

[0078] Preferably, the width of the effective sealing area 124 can be 8 mm.

[0079] In some embodiments, refer to Figure 5 As shown, the folded edge 140 is folded towards the first side 121.

[0080] In the above embodiment, the folded edge 140 is folded toward the first side 121, that is, the folded edge 140 is folded toward the frame 200. The boundary of the folded edge 140 can extend out of the side plate 220 of the frame 200 and be folded toward the side plate 220 of the frame 200. In this way, when the connecting part 120 is subjected to force, the lever arm is longer, making it less prone to deformation.

[0081] In some embodiments, refer to Figure 6 As shown, the folded edge 140 is folded towards the second side 122.

[0082] In the above embodiment, the folded edge 140 is folded towards the second side 122, that is, the folded edge 140 is folded towards the side away from the frame 200. The boundary of the folded edge 140 can be flush with the boundary of the side plate 220, and the folded edge 140 is folded towards the side away from the frame 200, which can avoid direct contact between the folded edge 140 and the components provided on the side plate 220 of the frame 200, and prevent interference between the battery pack cover 100 and the frame 200 during installation, thus preventing inconvenience in installation.

[0083] Specifically, refer to Figure 7 As shown, in the battery pack, the charging and discharging connectors, the feed channel and discharge channel of the cold plate are all led out of the frame 200 through the side plate 220, and the side plate 220 is also equipped with devices such as explosion-proof valves. Therefore, in order to avoid direct contact between the folded edge 140 and the above-mentioned devices, the folded edge 140 is set to fold towards the side away from the frame 200.

[0084] The folding direction of the folded edge 140 can be selected according to the actual use situation, and this application does not impose too many restrictions on it.

[0085] In some embodiments, refer to Figure 1 and Figure 2 As shown, the folded edge 140 includes a first folded edge plate 141 and a second folded edge plate 142 connected in sequence.

[0086] The end of the second folded edge plate 142 that is away from the first folded edge plate 141 is connected to the connecting part 120.

[0087] In the above embodiment, the folded edge 140 is formed by a first folded edge plate 141 and a second folded edge plate 142, and the second folded edge plate 142 is used to connect with the connecting part 120.

[0088] Specifically, refer to Figure 2 , Figure 5 and Figure 6 As shown, the first folded edge plate 141 can be a straight plate, and the second folded edge plate 142 can be an arc-shaped plate. The inner arc of the second folded edge plate 142 faces the frame 200, so that the first folded edge plate 141 extends toward the frame 200; or, the inner arc of the second folded edge plate 142 faces away from the frame 200, so that the first folded edge plate 141 extends toward the side facing away from the frame 200.

[0089] The second folded edge plate 142 has an arc-shaped plate structure, which can effectively disperse stress and reduce stress concentration, thereby improving the connection stability with the connecting part 120.

[0090] Among them, reference Figure 1 and Figure 2 As shown, the first folded edge plate 141, the second folded edge plate 142 and the connecting part 120 can be integrally formed by bending, so that the three have a high connection strength.

[0091] In some embodiments, refer to Figures 1 to 4 As shown, the folded edge 140 has at least one clearance notch 143, which is provided corresponding to the bend of the connecting portion 120.

[0092] In the above embodiment, the clearance notch 143 of the folded edge 140 is provided corresponding to the bending and turning point of the connecting part 120, that is, the folded edge 140 is broken at the bending and turning point of the connecting part 120 to avoid stress concentration.

[0093] Furthermore, referring to Figure 2 and Figure 5 As shown, when the folded edge 140 is folded toward the side away from the frame 200, avoiding the notch 143 can prevent water from accumulating on the connecting part 120.

[0094] For example, the extension height of the folded edge 140 can be 3mm to 7mm. This avoids the folded edge 140 being too high and interfering with other structures. Alternatively, it avoids the folded edge 140 being too low, so that it cannot play its role in improving the structural strength of the connecting part 120.

[0095] Specifically, the extension height of the 140mm fold can be 5mm.

[0096] Among them, reference Figure 1 and Figure 3 As shown, a reinforcing rib 111 may be provided on the side of the upper cover body 110 away from the frame 200 to enhance the structural strength of the upper cover body 110. Furthermore, the upper cover reinforcing rib 111 is located on the side of the upper cover body 110 away from the frame 200 to avoid occupying the internal space of the frame 200, which would result in an excessively large overall volume of the battery pack.

[0097] In the battery pack, a charging / discharging connector bracket 300 is typically provided on the side plate 220 of the frame 200 for extending the charging / discharging connector out of the frame 200. A receiving cavity is formed between the charging / discharging connector bracket 300 and the side plate 220 to accommodate part of the charging / discharging connector.

[0098] In some embodiments, refer to Figure 1 , Figure 3 and Figure 7 As shown, a docking portion 112 is provided on one side of the upper cover body 110, which is used to correspond to the receiving cavity. A clearance position 125 is provided on one of the connecting portions 120. When the connecting portion 120 is connected to the upper cover body 110, the clearance position 125 is connected to one side of the docking portion 112. The clearance position 125 is used to connect with the charging and discharging connector bracket 300.

[0099] The clearance portion 125 is provided with a reinforcing portion 150 and a fixing hole 130, and the clearance portion 125 is provided with a folded edge 140 on the side away from the docking portion 112.

[0100] In the above embodiments, when the battery pack cover 100 provided in this application is placed on the frame 200, the mating part 112 on the cover body 110 corresponds to the receiving cavity, and the clearance part 125 corresponds to the charging and discharging connector bracket 300. The clearance part 125 is connected to the charging and discharging connector bracket 300 by fasteners through the fixing hole 130 on the clearance part 125, thereby improving the sealing between the charging and discharging connector bracket 300 and the battery pack cover 100.

[0101] Furthermore, the reinforcing part 150 and the folded edge 140 provided on the clearance part 125 can improve the structural strength of the clearance part 125 and reduce the situation where the clearance part 125 deforms and warps due to its own deformation.

[0102] The structure of the reinforcing part 150, the folded edge 140 and the fixing hole 130 provided on the clearance part 125 can be the same as the rest of the connecting parts 120, and will not be described in detail here.

[0103] Reference Figure 1 and Figure 7 As shown, the present application provides a battery pack including a frame 200 and a battery pack cover 100 as described above. The battery pack cover 100 is disposed on the frame 200, and the connecting portion 120 of the battery pack cover 100 is used to connect with the frame 200.

[0104] In this embodiment, since the battery pack adopts the battery pack cover 100 in the above embodiment, it also has the advantages and benefits brought by the battery pack cover 100. That is, without setting the pressure strip, it can also improve the structural strength of the connecting part 120 and avoid the connecting part 120 from local deformation and warping to improve the sealing performance between the battery pack cover 100 and the frame 200, so as to reduce the overall weight of the battery pack and reduce the manufacturing cost.

[0105] This application provides a vehicle including a vehicle body and the battery pack described above, the battery pack being disposed within the vehicle body.

[0106] In the above structural configuration, since the vehicle uses the battery pack in the above embodiment, it also has the advantages and benefits brought by the battery pack, which will not be elaborated further here.

[0107] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not disclosed herein.
