The present application also provides a battery pack, comprising the mounting seat of the battery pack described in any of the above embodiments and the battery pack body of the battery pack described in any of the above embodiments, the battery pack body being slidably connected to the sliding boss.

[0034] See also Figure 1 , which is a schematic structural diagram of a battery pack 10 according to an embodiment.

[0035] See also Figure 2 The battery pack 10 of one embodiment includes a mounting seat 100 and a battery pack body 200. The mounting seat 100 is used to be detachably connected to the battery pack body 200, and the mounting seat 100 includes a fixed plate body 110 and a connecting plate 120, and the connecting plate 120 is connected to the fixed plate body 110. The connecting plate 120 is provided with a sliding boss 122, and the sliding boss 122 is slidably connected to the battery pack body 200. Figure 1The arrow v indicates the sliding direction of the sliding boss and the battery pack body. In this embodiment, the fixing plate 110 is used to be installed at the installation position, such as a sofa or a table and chair, so that the connecting plate 120 is installed at the installation position through the fixing plate 110.

[0036] When the mounting base 100, the battery pack body 200 and the battery pack 10 are used, the fixing plate 110 is fixedly connected to the target position of the product. Since the connecting plate 120 is connected to the fixing plate 110, and the connecting plate 120 is provided with a sliding boss 122, the sliding boss 122 is slidably connected to the battery pack body 200. When the battery pack body 200 needs to be disassembled, it is only necessary to slide the sliding boss 122 and the battery pack body 200 away from each other, which is convenient and quick. In this way, there is no need to remove the battery pack body 200 from the connecting plate 120. By operating with the aid of tools, the battery pack main body 200 and the mounting base 100 can be quickly disassembled and assembled by hand, which solves the problem of poor disassembly and assembly convenience of the battery pack 10 and greatly improves the service life of the battery pack 10; since there is no need to use fixings to fix the mounting base 100 and the battery pack main body 200, that is, the sliding boss 122 of the connecting plate 120 of the mounting base 100 is installed in sliding connection with the battery pack main body 200, there is no problem of damaging the fixings due to improper force controlled by the operator, which solves the problem of low service life of the battery pack 10.

[0037] like Figure 1 As shown, in one embodiment, the connecting plate 120 is provided with a connecting notch 121. The mounting base 100 further includes an elastic sheet 130, which is located in the connecting notch 121 and connected to the connecting plate 120. The elastic sheet 130 is used to elastically abut against the battery pack body 200, so that the elastic sheet 130 and the battery pack body 200 are reliably positioned to avoid the problem of separation between the elastic sheet 130 and the battery pack body 200.

[0038] like Figure 1 As shown, further, the elastic sheet 130 includes an elastic sheet body 131 and a connecting portion 133 connected to each other, and the elastic sheet body 131 is connected to the connecting plate 120 through the connecting portion 133, so that the elastic sheet 130 is connected to the connecting plate 120. In this embodiment, the elastic sheet body 131 is bent, and the elastic sheet body 131 is bent in a direction close to the battery pack body 200, so that the elastic sheet body 131 is better elastically abutted against the battery pack body 200. Further, the elastic sheet body 131 and the connecting portion 133 are integrally formed, so that the elastic sheet body 131 and the connecting portion 133 are firmly connected, and at the same time, the structure of the elastic sheet 130 is more compact. It can be understood that in other embodiments, the elastic sheet body 131 and the connecting portion 133 can also be formed separately and connected together by welding.

[0039] like Figure 1 As shown, in order to avoid cracking at the connection between the connection part 133 and the connection plate 120, the connection between the connection part 133 and the connection plate 120 is further rounded excessively, thereby avoiding the formation of large stress at the connection between the connection part 133 and the connection plate 120, thereby avoiding cracking at the connection between the connection part 133 and the connection plate 120.

[0040] like Figure 1 As shown, in one embodiment, the elastic sheet 130 and the connecting plate 120 are integrally formed, so that the elastic sheet 130 and the connecting plate 120 are firmly connected, and the structure of the mounting seat 100 is relatively compact. Specifically, the elastic sheet 130 and the connecting plate 120 are integrally stamped and formed, so that the molding difficulty of the mounting seat 100 is relatively low. It can be understood that in other embodiments, the elastic sheet 130 and the connecting plate 120 are not limited to being integrally formed. For example, the elastic sheet 130 and the connecting plate 120 can also be formed separately, and the elastic sheet 130 is connected to the connecting plate 120 by welding or gluing.

[0041] like Figure 2 As shown, in one embodiment, there are two connecting plates 120, namely a first connecting plate 120a and a second connecting plate 120b. The first connecting plate 120a and the second connecting plate 120b are relatively connected to the fixed plate body 110, so that the first connecting plate 120a and the second connecting plate 120b are arranged opposite to each other. The number of the sliding bosses 122 is at least two, and the first connecting plate 120a and the second connecting plate 120b are both protruding with at least one sliding boss 122, that is, the first connecting plate 120a is protruding with at least one sliding boss 122, and the second connecting plate 120b is protruding with at least one sliding boss 122, so that the first connecting plate 120a and the second connecting plate 120b are respectively slidably connected to the battery pack body 200 through the corresponding sliding bosses 122.

[0042] Furthermore, the number of the elastic sheets 130 is two, namely, a first elastic sheet and a second elastic sheet. The first elastic sheet is located in the connection notch 121 of the first connecting plate 120a and is connected to the first connecting plate 120a, and the second elastic sheet is located in the connection notch 121 of the second connecting plate 120b and is connected to the second connecting plate 120b. The first elastic sheet and the second elastic sheet are used to elastically abut against two opposite side walls of the battery pack body 200, respectively, so that the mounting seat 100 and the battery pack body 200 are elastically abutted, and the mounting seat 100 and the battery pack body 200 are slidably connected. When the mounting seat 100 and the battery pack body 200 need to be disassembled, the battery pack body 200 is separated from the mounting seat 100 along the sliding direction of the mounting seat 100 and the battery pack body 200 by a predetermined thrust, so that the battery pack body 200 is disassembled. When the battery pack body 200 needs to be installed on the mounting seat 100 , the two sides of the battery pack body 200 are slidably connected to the first connecting plate 120 a and the second connecting plate 120 b respectively, which is convenient and quick.

[0043] like Figure 2 and Figure 3 As shown, in order to enable the first connecting plate 120a and the second connecting plate 120b to be better slidably connected to the battery pack body 200 through the corresponding sliding bosses 122, in one embodiment, the first connecting plate 120a and the second connecting plate 120b are arranged in parallel to avoid the sliding boss 122 from getting stuck during the sliding process relative to the side wall of the battery pack body 200, so that the first connecting plate 120a and the second connecting plate 120b can be better slidably connected to the battery pack body 200 through the corresponding sliding bosses 122.

[0044] In order to make the first elastic sheet and the second elastic sheet elastically contact the two side walls of the battery pack body 200, in one embodiment, the first elastic sheet and the second elastic sheet are bent in a direction close to each other, so that the first elastic sheet and the second elastic sheet are reliably elastically contacted with the two side walls of the battery pack body 200, while reducing the volume of the mounting base 100. Furthermore, the bending part of the first elastic sheet is located between the first elastic sheet and the second elastic sheet, and the bending part of the second elastic sheet is located between the first elastic sheet and the second elastic sheet, so that the bending part of the first elastic sheet and the bending part of the second elastic sheet are reliably elastically contacted with the two side walls of the battery pack body 200.

[0045] like Figure 4 and Figure 5As shown, in one embodiment, the battery pack body 200 is provided with a sliding groove 210, and the inner wall of the sliding groove 210 is used to be slidably connected with the sliding boss 122, so that the battery pack body 200 and the mounting seat 100 are reliably slidably connected. In this embodiment, there are two sliding grooves 210, and the two sliding grooves 210 are respectively provided on the two side walls of the battery pack body 200, and the sliding boss 122 of the first connecting plate 120a and the sliding boss 122 of the second connecting plate 120b are respectively slidably connected in the two sliding grooves 210.

[0046] like Figure 4 and Figure 5 As shown, in order to enable the battery pack body 200 to slide axially relative to the mounting seat 100, further, the sliding groove 210 extends axially along the battery pack body 200, and the sliding groove 210 is opened on the side wall of the battery pack body 200, so that the battery pack body 200 slides axially relative to the mounting seat 100.

[0047] like Figure 4 and Figure 5 As shown, in this embodiment, the elastic sheet 130 elastically abuts against the inner wall of the sliding groove 210. In one embodiment, an abutting flange 212 is provided on the inner wall of the sliding groove 210, and the abutting flange 212 is used to elastically abut against the elastic sheet 130 of the mounting seat 100, so as to avoid the problem of slipping easily occurring at the abutment between the elastic sheet 130 and the inner wall of the sliding groove 210, so that the elastic sheet 130 reliably elastically abuts against the inner wall of the sliding groove 210. Further, the abutting flange 212 is formed with an abutting groove 212a, and the elastic sheet 130 abuts in the abutting groove 212a, so that the abutting flange 212 and the elastic sheet 130 of the mounting seat 100 are better elastically abutted. Specifically, the abutting flange 212 includes a first abutting platform 2122 and a second abutting platform 2124 connected to each other. The first abutting platform 2122 and the second abutting platform 2124 are both connected to the inner wall of the sliding groove 210. The first abutting platform 2122 and the second abutting platform 2124 jointly form an abutting groove 212a, so that the abutting flange 212 is formed with the abutting groove 212a. In this embodiment, the bending part of the elastic sheet 130 abuts against the first abutting platform 2122 and the second abutting platform 2124 respectively, that is, the bending part of the elastic sheet 130 is located in the abutting groove 212a and abuts against the abutting flange 212, so that the elastic sheet 130 and the abutting flange 212 reliably elastically abut.

[0048] In order to improve the adaptability of the relative positioning connection between the mounting seat and the battery pack body, further, the abutment flange is slidably arranged in the sliding groove, so that the position of the abutment flange in the sliding groove is adjustable, and then the relative positioning position of the mounting seat and the battery pack body is adjustable, so that the battery pack body can be better adapted to the mounting seats of different models. In other words, for mounting seats with elastic sheets in different positions, the battery pack body can be elastically abutted and positioned with the mounting seat. Specifically, the shell is also provided with a positioning connection groove, the positioning connection groove is connected to the sliding groove, the abutment flange part is located in the positioning connection groove and is slidably connected to the shell, so that the abutment flange is slidably arranged in the sliding groove. Further, the shell is also provided with a plurality of positioning holes, and the plurality of positioning holes are arranged side by side along the extension direction of the positioning connection groove, and the extension direction of the positioning connection groove is the same as the extension direction of the sliding groove. The battery pack body also includes an adjusting member, which is respectively inserted into one of the positioning holes and the positioning connection groove, so that the abutment flange is positioned and connected in the sliding groove. When the position of the abutting flange needs to be adjusted, the adjusting member is loosened, the abutting flange is slid to make the abutting flange slide relative to the positioning connection groove, that is, the abutting flange slides to a predetermined position relative to the sliding groove, and finally the adjusting member is tightened to achieve the position adjustment of the abutting flange. In this embodiment, the adjusting member is a screw or a bolt.

[0049] like Figure 4 and Figure 5 As shown, it should be noted that abutment flanges 212 are provided on the inner walls of the two sliding grooves 210, so that the first elastic sheet and the second elastic sheet are elastically abutted against the abutment flanges 212 of the inner walls of the corresponding sliding grooves 210, respectively, so that both sides of the battery pack body 200 are reliably positioned and connected to the mounting seat 100.

[0050] like Figure 4 and Figure 5 As shown, further, the cross section of the sliding boss 122 along the sliding direction parallel to the sliding boss 122 is rectangular, so that the sliding boss 122 slides smoothly in the sliding groove 210. In this embodiment, the sliding groove 210 is a rectangular groove body, and the width of the sliding groove 210 along the sliding direction perpendicular to the sliding boss 122 is equal to the width of the sliding boss 122, wherein Figure 4 The relative sliding direction v between the sliding boss and the sliding groove is shown, so that the sliding boss 122 will not shake during the sliding process along the sliding groove 210. Figure 2 Furthermore, a circular chamfer is provided on the peripheral wall of the sliding boss 122, so that the edges and corners of the sliding boss 122 are excessively rounded, so that the sliding boss 122 can quickly slide into the sliding groove 210, while reducing the wear resistance between the sliding boss 122 and the inner wall of the sliding groove 210. In this embodiment, the projection of the sliding boss on the connecting plate is waist-shaped, so that the sliding boss can slide smoothly and reliably in the sliding groove.

[0051] See again Figure 5 Furthermore, a guiding slope 214 is formed on the inner wall of the end of the sliding groove 210 adjacent to the battery pack body 200, so that the sliding boss 122 can slide into the appropriate position in the sliding groove 210 through the guiding slope 214, thereby enabling the sliding boss 122 to quickly slide into the sliding groove 210, while reducing the relative sliding resistance between the battery pack body 200 and the mounting seat 100.

[0052] See again Figure 2 In order to better mold the sliding boss 122 on the connecting plate 120 and reduce the difficulty of molding the sliding boss 122, further, a demolding groove 123 is formed on the side wall of the connecting plate 120 away from the sliding boss 122 at a position corresponding to the sliding boss 122, so that the sliding boss 122 can be better molded on the connecting plate 120 and reduce the difficulty of molding the sliding boss 122.

[0053] See again Figure 1 and Figure 2In this embodiment, the fixed plate body 110 is connected to the first connecting plate 120a and the second connecting plate 120b respectively, so that the first connecting plate 120a, the fixed plate body 110 and the second connecting plate 120b together form a U-shaped mounting seat 100, and then the mounting seat 100 forms a U-shaped mounting slot 102. The battery pack body 200 is located in the mounting slot 102, and the sliding bosses 122 of the first connecting plate 120a and the second connecting plate 120b are respectively slidably connected to the opposite side walls of the battery pack body 200. The first connecting plate 120a and the second connecting plate 120b are both provided with a connecting notch 121. There are two elastic sheets 130, one of which is located in the connection notch 121 of the first connecting plate 120a and connected to the first connecting plate 120a, and the other elastic sheet 130 is located in the connection notch 121 of the second connecting plate 120b and connected to the second connecting plate 120b, so that the two elastic sheets 130 are respectively connected to the first connecting plate 120a and the second connecting plate 120b, and at the same time, the two elastic sheets 130 are respectively elastically abutted against the two sides of the battery pack body 200. Further, the first connecting plate 120a is convexly provided with at least one sliding boss 122, and the second connecting plate 120b is convexly provided with at least one sliding boss 122, and the sliding boss 122 of the first connecting plate 120a and the sliding boss 122 of the second connecting plate 120b are both located in the mounting notch 102. There are two sliding grooves 210, which are respectively opened on both sides of the battery pack body 200. The sliding boss 122 of the first connecting plate 120a and the sliding boss 122 of the second connecting plate 120b are respectively slidably connected in the corresponding sliding grooves 210, so that the sliding boss 122 of the first connecting plate 120a and the sliding boss 122 of the second connecting plate 120b are respectively slidably connected to both sides of the battery pack body 200, thereby making the process of disassembling and assembling the battery pack body 200 on the mounting seat 100 more convenient and quick.

[0054] See again Figure 1 and Figure 2 Furthermore, the two elastic sheets 130 are bent in a direction approaching each other, and the bending parts of the two elastic sheets 130 are both located in the mounting groove 102. The battery pack body 200 is located in the mounting groove 102, and the two sides of the battery pack body 200 are elastically abutted against the two elastic sheets 130 respectively, avoiding the problem of separation between the battery pack body 200 and the mounting seat 100, thereby making the battery pack body 200 and the mounting seat 100 reliably elastically abutted.

[0055] See again Figure 1 and Figure 2In one embodiment, the fixed plate body 110 includes at least two bending protrusions 113, and the rounded corners between two adjacent bending protrusions 113 are transitioned to reduce the stress between the two adjacent bending protrusions 113, and at the same time, the first connecting plate 120a and the second connecting plate 120b are elastically connected to the two sides of the battery pack body 200 respectively. Under the joint action of the bending protrusions 113 and the elastic sheet 130, the battery pack body 200 is better connected and positioned with the mounting seat 100 after being installed on the mounting seat 100. In this embodiment, there are three bending protrusions 113, and the three bending protrusions 113 are connected side by side. The first bending protrusion 113 is connected to the first connecting plate 120a, and the second bending protrusion 113 is connected to the second connecting plate 120b, so that the fixed plate body 110 is connected to the first connecting plate 120a and the second connecting plate 120b respectively. Furthermore, there are multiple bending protrusions, and the multiple bending protrusions are distributed in a wave shape, so that the fixed plate body has better elastic deformation performance.

[0056] See again Figure 1 and Figure 2 In one embodiment, the fixed plate body 110 is provided with a reinforcing rib 114, and the reinforcing rib 114 is connected to the inner wall of any of the bent protrusions 113 to enhance the structural strength of the fixed plate body 110 and prevent the fixed plate body 110 from being deformed too much. In this embodiment, the reinforcing rib 114 is connected to the inner walls of the three bent protrusions 113 respectively.

[0057] See again Figure 1 and Figure 2 In this embodiment, the first connecting plate 120a, the fixed plate body 110 and the second connecting plate 120b are integrally stamped and formed, so that the fixed plate body 110 is reliably connected to the first connecting plate 120a and the second connecting plate 120b respectively, and the structure of the mounting base 100 is more compact. In other embodiments, the first connecting plate 120a, the fixed plate body 110 and the second connecting plate 120b can also be formed separately and connected together by welding or gluing.
