[0041] 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 represent 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.

[0042] In related technologies, a battery pack includes battery modules and a distribution box electrically connected to the battery modules. Each battery module includes lead-out connectors and multiple batteries, with the lead-out connectors electrically connected to each battery. The lead-out connectors are electrically connected to the distribution box via copper busbars. However, the distance between the lead-out connectors and the distribution box is relatively large, resulting in a long copper busbar span. During use, vibrations are more likely to occur in the central area of ​​the copper busbar, and the vibration amplitude is relatively large, making the copper busbar more prone to breakage. The electrical connections between the copper busbar and the lead-out connectors and the distribution box are also more prone to breakage and failure.

[0043] Based on this, this application provides a battery pack that reduces the vibration amplitude of the electrical connector by connecting the electrical connector to the top of the accommodating cavity, prevents the electrical connector from vibrating significantly, increases the overall fatigue strength and connection stiffness of the electrical connector, increases the modalities of the electrical connector, and reduces the possibility of electrical connection failure and breakage of the electrical connector.

[0044] The embodiments of this application are described below with reference to the accompanying drawings.

[0045] Reference Figures 1 to 5 The battery pack provided in this application embodiment includes: a housing and an electrical connector 100, the housing having a receiving cavity. The electrical connector 100 is located in the receiving cavity and connected to the top of the receiving cavity.

[0046] For example, in this embodiment of the application, the housing includes a battery tray and a cover plate disposed on top of the battery tray, so that the battery tray and the cover plate together form an accommodating cavity. It can be understood that the cover plate is the top wall of the housing, and the side of the cover plate facing the accommodating cavity is the top of the accommodating cavity.

[0047] The electrical connector 100 can be a copper busbar, an aluminum busbar, or a copper-aluminum busbar.

[0048] In some embodiments, the battery pack also includes a battery pack and a distribution box; the battery pack and the distribution box are located in the accommodating cavity and are electrically connected via an electrical connector 100.

[0049] In some embodiments, the electrical connector 100 may be a copper busbar, aluminum busbar, or copper-aluminum busbar with an insulating layer. In this way, the electrical connector 100 can not only realize the electrical connection between the battery pack and the distribution box, but also prevent electrical conduction between the electrical connector 100 and other structural components installed in the accommodating cavity, thereby avoiding internal short circuits and leakage in the battery pack and improving the safety of the battery pack.

[0050] In this embodiment, the electrical connector 100 and the inner side of the cover plate can be connected by snap-fit, adhesive, or other methods. Alternatively, the electrical connector 100 can be fixed to the inner side of the cover plate using threaded fasteners; there are no limitations on this. Thus, the connection between the electrical connector 100 and the inner side of the cover plate, through which the cover plate provides both connection and support for the electrical connector 100, reduces the amplitude of vibration of the electrical connector 100, further preventing electrical connection failure of the battery pack caused by the breakage of the electrical connector 100, and improving the operational stability and safety of the battery pack.

[0051] Understandably, there are many ways to connect the electrical connector 100 to the inside of the cover. As an optional implementation, the battery pack also includes a bracket 200, which is located in the receiving cavity; the electrical connector 100 is connected to the top of the receiving cavity through the bracket 200.

[0052] For example, the bracket 200 can be an insulating component, such as being made of a plastic material. The plastic material has a certain degree of toughness. The plastic material can be polyphenylene sulfide (PPS), or it can be a polyamide (PA) resin composite material with added glass fiber (GF). In this way, the electrical connector 100 is connected to the inner side of the cover plate via the insulating bracket 200, forming an insulating barrier between the battery pack casing and the electrical connector 100, reducing the possibility of accidental electrical conduction between the electrical connector 100 and the casing, thereby improving battery pack safety.

[0053] Specifically, the electrical connector 100 has electrical connection portions 140 at both ends, which are electrically connected to the battery pack and the distribution box, respectively. The middle region of the electrical connector 100 can be connected to the bracket 200, and the top of the bracket 200 is connected to the inner side of the cover plate. Thus, the electrical connector 100 is connected to the cover plate via the bracket.

[0054] For example, the distribution box has electrical connection points, the battery pack has lead-out tabs, and two electrical connection portions 140 are correspondingly electrically connected to the electrical connection points and the lead-out tabs. In some embodiments, the electrical connection portions 140 are connected to the distribution box and the battery pack by screws to electrically connect the electrical connection portions 140 to the distribution box and the battery pack.

[0055] In some embodiments, the bracket 200 can be bonded to the cover plate. Thus, during battery pack assembly, the distribution box and battery pack are first fixed to the battery tray. Then, the electrical connection portions 140 at both ends of the electrical connector 100 are electrically connected to the distribution box and battery pack, and the bracket 200 is connected to the electrical connector 100. After the electrical connector 100 is connected to the bracket 200, structural adhesive is applied to the bracket 200, and then the cover plate is placed on the battery tray, so that the bracket 200 is bonded to the cover plate through the structural adhesive, thereby fixing the bracket 200 to the cover plate. Therefore, there is no need to add a fixing structure for fixing the bracket 200 or the electrical connector 100 to the battery tray, and no need to change the structure of the battery tray and cover plate.

[0056] The battery pack provided in this application embodiment, by setting a bracket 200, connecting the electrical connector 100 to the bracket 200, and bonding the bracket 200 to the cover plate, allows the electrical connector 100 to be indirectly fixed to the cover plate through the bracket 200. This reduces the vibration amplitude of the electrical connector 100, prevents large-scale vibration of the electrical connector 100, increases the overall fatigue strength and connection stiffness of the electrical connector 100, increases the modal strength of the electrical connector 100, and reduces the possibility of electrical connection failure at the electrical connection part 140 and the possibility of breakage of the electrical connector 100. Furthermore, the bracket 200 can be directly bonded to the cover plate, eliminating the need to add a fixing structure for the electrical connector 100 or the bracket 200 to the cover plate or battery tray, and requiring no changes to the outer shell structure, making implementation relatively convenient.

[0057] Reference Figure 2 and Figure 3 In a specific implementation, the bracket 200 has an adhesive part 211, which is bonded to the cover plate by structural adhesive.

[0058] For example, the adhesive portion 211 can be the top surface of the bracket 200, and the top surface of the bracket 200 is bonded to the cover plate.

[0059] In some examples, the adhesive portion 211 has at least one of a protrusion and a groove to increase the bonding area between the structural adhesive and the adhesive surface, thereby improving the strength of the bond between the adhesive surface and the structural adhesive.

[0060] Specifically, when installing the bracket 200 on the cover plate, structural adhesive is first applied to the adhesive part 211, and then the structural adhesive is brought into contact with the cover plate. After the structural adhesive cures, the adhesive part 211 can be bonded to the cover plate.

[0061] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments, the adhesive portion 211 has an adhesive reservoir 212 for collecting structural adhesive, the opening of which faces the cover plate.

[0062] The structural adhesive is typically liquid. When applied to the adhesive portion 211, it readily flows out. The adhesive portion 211 is located on one side of the opening of the adhesive reservoir 212, allowing the structural adhesive flowing out of the adhesive portion 211 to flow into the adhesive reservoir 212 through the opening. This allows the adhesive to be collected in the adhesive reservoir 212, preventing excessive thickness of structural adhesive on the adhesive portion 211 and ensuring reliable bonding between the adhesive portion 211 and the outer casing. It also prevents excessive thickness of structural adhesive on the adhesive portion 211 from compressing the electrical connector 100 and causing deformation due to stress.

[0063] For example, the volume of the adhesive reservoir 212 can be 0.5 times the volume of the structural adhesive applied to the adhesive portion 211.

[0064] Reference Figure 2 In some embodiments, the periphery of the opening of the adhesive reservoir 212 has at least one overflow port 213.

[0065] In this way, when there is too much structural adhesive in the adhesive reservoir 212, some of the structural adhesive can overflow through the overflow port 213 to ensure that the structural adhesive on the bonding part 211 can continue to flow into the adhesive reservoir 212, and to avoid the structural adhesive on the bonding part 211 being too thick in some areas.

[0066] Reference Figure 2 and Figure 4 In some embodiments, the adhesive portion 211 includes at least one adhesive limiting rib 214, which is located around the opening of the adhesive receiving groove 212 and abuts against the cover plate.

[0067] Among them, the adhesive limiting rib 214 is a raised rib. By making the adhesive limiting rib 214 abut against the cover plate, the thickness of the structural adhesive between the adhesive part 211 and the cover plate is made to be equivalent to the height of the adhesive limiting rib 214. This allows the thickness of the structural adhesive between the adhesive part 211 and the cover plate to be limited, preventing the thickness of the structural adhesive between the adhesive part 211 and the cover plate from being too large or too small, and ensuring the stability of the bonding between the adhesive part 211 and the cover plate.

[0068] It is understood that the shape of the adhesive-limiting rib 214 can be adapted to actual needs, and this embodiment does not impose any restrictions on it.

[0069] In some embodiments, the electrical connector 100 passes through the bracket 200. For example, the bracket may be provided with a communication structure, such as a communication slot or a communication hole, and the electrical connector 100 is connected to the bracket 200 through the communication structure.

[0070] Reference Figure 2 , Figure 3 and Figure 4 In its specific implementation, the bracket 200 includes a mounting member 210, a first fixing member 220, and a second fixing member 230. The first fixing member 220 and the second fixing member 230 are disposed opposite to each other. The mounting member 210 connects the first fixing member 220 and the second fixing member 230 to the same side and is connected to the cover plate. The first fixing member 220, the second fixing member 230, and the mounting member 210 together define a limiting groove 201. The electrical connector 100 passes through the limiting groove 201.

[0071] The top of the mounting component 210 forms an adhesive portion 211. It can be understood that the top of the mounting component 210 has an adhesive groove 212 and an adhesive limiting rib 214.

[0072] For example, the adhesive groove 212 is located on the mounting member 210 and is located between the first fixing member 220 and the second fixing member 230. The limiting groove 201 and the adhesive groove 212 are located on opposite sides of the mounting member 210.

[0073] Reference Figure 2 and Figure 4 In some embodiments, the first fixing member 220 includes at least one first spring piece 221, one side of which is connected to the mounting member 210, and the other side of which has a first limiting portion 222. The first limiting portion 222 abuts against the electrical connector 100 to limit the electrical connector 100 within the limiting groove 201; and / or, the second fixing member 230 includes at least one second spring piece 231, one side of which is connected to the mounting member 210, and the other side of which has a second limiting portion 232. The second limiting portion 232 abuts against the electrical connector 100 to limit the electrical connector 100 within the limiting groove 201.

[0074] When the electrical connector 100 is installed in the limiting groove 201, the side of the first spring 221 away from the mounting member 210 and the side of the second spring 231 away from the mounting member 210 can move toward the side away from the limiting groove 201, so as to increase the distance between the first spring 221 and the second spring 231 on the side away from the mounting member 210, thereby facilitating the electrical connector 100 to be inserted into the limiting groove 201 between the first spring 221 and the second spring 231.

[0075] Specifically, the first fixing member 220 includes at least one first spring piece 221, and the first spring piece 221 has a first limiting portion 222 on the side facing the second fixing member 230; the second fixing member 230 includes at least one second spring piece 231, and the second spring piece 231 has a second limiting portion 232 on the side facing the first fixing member 220. The first limiting portion 222 and the second limiting portion 232 are opposite to each other.

[0076] The first limiting part 222 and the second limiting part 232 both have a limiting surface 224 and a guide surface 225. When the electrical connector 100 is inserted into the limiting groove 201, the bracket 200 is first placed above the electrical connector 100, the first limiting part 222 and the second limiting part 232 are located below the bracket 200, and the electrical connector 100 abuts against the guide surface 225. Then, the electrical connector 100 is moved toward the limiting groove 201. At the same time, the electrical connector 100 can push a portion of the first spring piece 221 toward the side away from the inside of the limiting groove 201 through the guide surface 225, and push a portion of the second spring piece 231 toward the side away from the inside of the limiting groove 201. Once the electrical connector 100 has moved completely into the limiting groove 201, the electrical connector 100 disengages from the guide surface 225. Under the action of elastic force, the first spring piece 221 and the second spring piece 231 move toward the electrical connector 100 within the limiting groove 201, thus resetting the first spring piece 221 and the second spring piece 231. This makes it easier for the electrical connector 100 to pass through the limiting groove 201.

[0077] When the electrical connector 100 is inserted into the limiting groove 201, the limiting surface 224 abuts against the bottom surface of the electrical connector 100, so as to limit the electrical connector 100 by the first limiting part 222 and the second limiting part 232, preventing the electrical connector 100 from coming out of the limiting groove 201, thereby making the electrical connector 100 more stable.

[0078] For example, at least a portion of the electrical connector 100 has a rectangular longitudinal section. When the electrical connector 100 is located within the limiting groove 201, the limiting surface 224 is parallel to the horizontal plane, and the guide surface 225 is inclined relative to the limiting surface 224. The plane containing the guide surface 225 of the first limiting portion 222 intersects the plane containing the guide surface 225 of the second limiting portion 232 in a straight line, which passes through the limiting groove 201.

[0079] Reference Figure 2 In some embodiments, the first fixing member 220 further includes at least two first support plates 223, which are disposed on both sides of the first spring piece 221 and are connected to the mounting member 210; and / or, the second fixing member 230 further includes at least two second support plates 233, which are disposed on both sides of the second spring piece 231 and are connected to the mounting member 210.

[0080] Specifically, the first support plate 223 supports the first spring piece 221 to improve its stability and reliability. Similarly, the second support plate 233 supports the second spring piece 231 to improve its stability and reliability.

[0081] For example, there are two first spring pieces 221 and three first support plates 223. Each first support plate 223 is arranged sequentially along the extension direction of the limiting groove 201. The first spring piece 221 is arranged between two adjacent first support plates 223 and is connected to the two first support plates 223.

[0082] There are two second spring clips 231, each corresponding to a first spring clip 221. There are three second support plates 233, arranged sequentially along the extension direction of the limiting groove 201, with the first support plate 223 and the second support plate 233 parallel to each other. The second spring clips 231 are positioned between two adjacent second support plates 233 and connected to both second support plates 233.

[0083] In some examples, the bracket 200 also includes a plurality of support members 240, at least two of which are correspondingly connected to the first support plate 223 and the mounting member 210, and at least two of which are correspondingly connected to the second support plate 233 and the mounting member 210.

[0084] Specifically, the mounting member 210 is perpendicular to the first support plate 223 and the second support plate 233, and the support member 240 is perpendicular to the adhesive portion 211, and also perpendicular to the first support plate 223 and the second support plate 233. At least two support members 240 connect the first support plate 223 to the mounting member 210, and at least two support members 240 connect the second support plate 233 to the mounting member 210. By providing the support member 240, the first support plate 223, and the second support plate 233, the strength and stability of the bracket 200 are improved.

[0085] In some embodiments, the mounting member 210, the first fixing member 220, and the second fixing member 230 are integrally formed.

[0086] This reduces the assembly steps of the bracket 200, improving production efficiency. It also eliminates the connection points between the mounting component 210, the first fixing component 220, and the second fixing component 230, enhancing the overall strength and reliability of the bracket 200.

[0087] For example, the mounting member 210, the first fixing member 220 and the second fixing member 230 are integrally injection molded.

[0088] Reference Figure 1 , Figure 4 and Figure 5 In some embodiments, the central region of the electrical connector 100 has a torsion portion, at least a portion of which is connected to the bracket 200.

[0089] For example, at least a portion of the torsion portion is located within the limiting groove 201 so that the electrical connector 100 passes through the limiting groove 201. At least a portion of the torsion portion mates with the limiting groove 201.

[0090] For example, the central region of the electrical connector 100 is twisted 90 degrees in a clockwise or counterclockwise direction to form a twisted portion.

[0091] The electrical connector 100 is located on one side of the battery pack, and the electrical connector 100 and the battery pack are arranged along the width direction of the electrical connector 100. Due to the limited space inside the casing, the electrical connector 100 is relatively wide, resulting in a small distance between the electrical connector 100 and the battery pack. The electrical connector 100 is more likely to come into contact with or even collide with the battery pack. Especially during collision tests, the electrical connector 100 is more likely to penetrate the battery cells, which can easily cause a short circuit in the battery pack.

[0092] The thickness of the electrical connector 100 is relatively small compared to its width. In this embodiment, by twisting the middle region of the electrical connector 100, the thickness of the electrical connector 100 forms the width of the twisted portion. The reduced width of the twisted portion increases the distance between the electrical connector 100 and the battery pack, reducing the possibility of contact or even collision between the electrical connector 100 and the battery pack, lowering the risk of the electrical connector 100 intruding into the battery pack, and reducing the possibility of a short circuit in the battery pack. The limiting groove 201 limits the twisted portion, thereby limiting the electrical connector 100 and further preventing contact or collision between the electrical connector 100 and the battery pack.

[0093] In a specific implementation, the electrical connector 100 includes a vertical section 110, two torsional sections 120, and two horizontal sections 130. The vertical section 110 is located between the two horizontal sections 130. The torsional sections 120 connect the horizontal sections 130 and the vertical section 110. The vertical section 110 and the two torsional sections 120 form a torsional portion. At least a portion of the vertical section 110 passes through the bracket 200. The two horizontal sections 130, located away from the ends of the torsional sections 120, are respectively connected to the battery pack and the distribution box.

[0094] For example, the center line of the horizontal segment 130 extends along the extension direction of the horizontal segment 130, the center line of the vertical segment 110 extends along the extension direction of the vertical segment 110, and the center line of the horizontal segment 130 coincides with the center line of the vertical segment 110.

[0095] Based on the above embodiments, this application provides an electrical device, including a device body and any of the battery packs in the above embodiments, wherein the battery pack is disposed on the device body.

[0096] The specific structure of the battery pack has been described in detail in the above embodiments, and will not be repeated here.

[0097] The electrical equipment provided in this application embodiment can fix the electrical connector 100 on the top of the accommodating cavity by connecting the electrical connector 100 to the top of the accommodating cavity, thereby reducing the vibration amplitude of the electrical connector 100, preventing the electrical connector 100 from vibrating significantly, increasing the overall fatigue strength and connection stiffness of the electrical connector 100, increasing the modalities of the electrical connector 100, and reducing the possibility of electrical connection failure of the electrical connection part 140 and the possibility of breakage of the electrical connector 100.
