Detailed Implementation

[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is in conjunction with the appendix Figures 1-4 The connection components between the battery pack 2 and the vehicle frame 1 in this embodiment will be described in detail.

[0028] The battery pack 2 and the frame 1 connection assembly of this embodiment include the frame 1, the battery pack 2, and the connecting member 3. The frame 1 includes a frame body 11 and a first extension 12. The first extension 12 extends outward from at least one side of the frame body 11 in a first direction and has a first chamber 121. The first direction is parallel to the width direction of the frame 1. The battery pack 2 is placed on the frame 1 and includes a body 21 and a second extension 22. The second extension 22 extends outward from at least one side of the body 21 in the first direction. At least a portion of the second extension 22 overlaps with and is detachably connected to the first extension 12. The second extension 22 has a second chamber 221. At least a portion of the connecting member 3 passes through the first extension 12 and the second extension 22, and is detachably connected to the first extension 12 and the second extension 22 through the first chamber 121 and the second chamber 221.

[0029] In this embodiment, the connection assembly between the battery pack 2 and the frame 1 is provided with a first extension 12 extending outward on at least one side of the frame 11 in a first direction, and a second extension 22 extending outward on at least one side of the body 21 in a first direction. The first extension 12 and the second extension 22 are at least partially overlapped, so that at least a portion of the connecting member 3 passes through the first chamber 121 of the first extension 12 and the second chamber 221 of the second extension 22, thereby achieving a detachable connection between the first extension 12 and the second extension 22. Moreover, the arrangement of the first chamber 121 and the second chamber 221 makes both the first extension 12 and the second extension 22 hollow structures, which can improve the strength of the first extension 12 and the second extension 22, thereby making the connection between the battery pack 2 and the frame 1 more stable, preventing the battery pack 2 from shaking, and improving the user experience.

[0030] Furthermore, in this embodiment, the frame 1 and the battery pack 2 are connected by the connecting component 3 to form an integral structure, which can improve the rigidity and strength of the frame 1 and reduce the risk of frame 1 deformation during the riding of the mobility scooter.

[0031] Specifically, such as Figures 1-3As shown, the first extension 12 extends outward from at least one side of the frame 11 in the first direction. This can be understood as the first extension 12 being located on the first side of the frame 11 in the first direction, or the first extension 12 being located on the second side of the frame 11 in the first direction, or there being two first extensions 12, respectively located on the first and second sides of the frame 11 in the first direction. The second extension 22 extends outward from at least one side of the body 21 in the first direction. This can be understood as the second extension 22 being located on the first side of the body 21 in the first direction, or the second extension 22 being located on the second side of the body 21 in the first direction, or there being two second extensions 22, respectively located on the first and second sides of the frame 11 in the first direction. In this embodiment, there are two first extensions 12 and two extensions 22.

[0032] The stacking direction of the first extension 12 and the second extension 22 is consistent with the vertical direction. The battery pack 2 is placed at the bottom of the frame 1. The frame 1 is installed on the battery pack 2 from top to bottom so that at least a portion of the first extension 12 and the second extension 22 are opposite each other. The first extension 12 has an upper end plate and a lower end plate, and a first chamber 121 is formed between the upper end plate and the lower end plate of the first extension 12. The second extension 22 has an upper end plate and a lower end plate, and a second chamber 221 is formed between the upper end plate and the lower end plate of the second extension 22. At least a portion of the connecting member 3 passes through the first extension 12 and the second extension 22, so that the connecting member 3 passes through the upper end plate of the first extension 12, the lower end plate of the first extension 12, the upper end plate of the second extension 22, and the lower end plate of the second extension 22 from top to bottom, thereby connecting the four end plates and improving the connection stability between the first extension 12 and the second extension 22. This allows the battery pack 2 to be securely installed on the frame 1, preventing the battery pack 2 from shaking and improving the user experience.

[0033] In some embodiments, the connecting member 3 includes a first bushing 31 and a fastener 32, at least a portion of the second extension 22 is spaced from the first extension 12 in the stacking direction, at least a portion of the first bushing 31 is located between at least a portion of the second extension 22 and the first extension 12, and at least a portion of the fastener 32 passes through the first extension 12, at least a portion of the first bushing 31 and the second extension 22.

[0034] Specifically, such as Figure 3 and Figure 4As shown, the first extension 12 is located above the second extension 22. There is a gap between the lower end face of the first extension 12 and the upper end face of at least part of the second extension 22. At least part of the first bushing 31 is located in the gap between the lower end face of the first extension 12 and the upper end face of at least part of the second extension 22. This facilitates filling the gap between the first extension 12 and at least part of the second extension 22, and also facilitates the fastener 32 to pass through the first extension 12, the first bushing 31, and the second extension 22 sequentially from top to bottom, thereby improving the ease of connection.

[0035] In some embodiments, such as Figure 4 As shown, the first bushing 31 includes a first head 311 and a first body 312. The first head 311 is located between at least a portion of the second extension 22 and the first extension 12. The first body 312 passes through the first extension 12 and through the first chamber 121. At least a portion of the fastener 32 passes through the first bushing 31 and the second extension 22.

[0036] In this embodiment, the first head 311 of the first bushing 31 is disposed between at least a portion of the first extension 12 and the second extension 22, and the first body portion 312 of the first bushing 31 passes through the first extension 12. At least a portion of the fastener 32 passes through the first bushing 31 and the second extension 22, thereby preventing the fastener 32 from directly contacting the first extension 12. This can disperse the local pressure on the first extension 12, prevent the first extension 12 from deforming, and improve the connection reliability between the first extension 12 and the second extension 22.

[0037] Optionally, the first extension 12 has a first connecting hole that extends in the vertical direction, at least part of the first bushing 31 refers to the first head 311 of the first bushing 31, the first body 312 of the first bushing 31 passes through the first connecting hole in the upward direction, and the first head 311 of the first bushing 31 abuts against the lower end face of the first extension 12.

[0038] Optionally, the first bushing 31 and the first extension 12 are welded together.

[0039] In some embodiments, the fastener 32 includes a screw 321 and a second bushing 322, at least a portion of which is located at the end of the second extension 22 away from the first extension 12. The second bushing 322 is threadedly connected to the screw 321, and the screw 321 passes through the first bushing 31 and the second extension 22.

[0040] Specifically, such as Figure 2 and Figure 3As shown, at least a portion of the second bushing 322 is located at the lower end of the second extension 22. The screw 321 passes through the first bushing 31 and the second extension 22 in a top-to-bottom direction and is threadedly connected to at least a portion of the second bushing 322. The connection between the first extension 12 and the second extension 22 is achieved through the threaded connection between the screw 321 and at least a portion of the second bushing 322, and the connection method is simple and reliable.

[0041] It is understandable that the preload of the screw 321 is relatively large. The first bushing 31 and the second bushing 322 can protect the first extension 12 and the second extension 22, prevent deformation of the first extension 12 and the second extension 22, and improve the reliability of the connection.

[0042] In some embodiments, such as Figure 3 As shown, the second bushing 322 includes a second head 3221 and a second body 3222. The second head 3221 is located at the end of the second extension 22 away from the first extension 12. The second body 3222 passes through the second extension 22 and through the second chamber 221. The screw 321 passes through the second bushing 322.

[0043] In this embodiment, the second head 3221 of the second bushing 322 is located at the end of the second extension 22 away from the first extension 12, and the second body 3222 of the second bushing 322 is inserted into the second extension 22. The screw 321 is inserted through the second bushing 322 to avoid direct contact between the screw 321 and the second extension 22. This can disperse the local pressure on the second extension 22, prevent the second extension 22 from deforming, and improve the connection reliability between the first extension 12 and the second extension 22.

[0044] Optionally, the second extension 22 has a second connecting hole that extends in the vertical direction, at least part of the second bushing 322 refers to the second head 3221 of the second bushing 322, the second body portion 3222 of the second bushing 322 passes through the second connecting hole in the upward direction, and the second head 3221 of the second bushing 322 abuts against the lower end face of the second extension 22.

[0045] Optionally, the second bushing 322 and the second extension 22 are welded together.

[0046] In some embodiments, such as Figure 3 As shown, the second bushing 322 and the first bushing 31 are opposite and abut against each other in the stacking direction. By making the second bushing 322 and the first bushing 31 opposite and abut against each other in the stacking direction, it is convenient to quickly position the first extension 12 and the second extension 22, thereby allowing the screw 321 to pass through the first bushing 31 and the second bushing 322 in sequence, improving the convenience and accuracy of connection.

[0047] In some embodiments, the second extension 22 includes a first portion 222 and a second portion 223. The first portion 222 extends outward from at least one side of the body 21 in a first direction and is inclined downward. The second portion 223 is connected to the free end of the first portion 222 and overlaps with the first extension 12. The second chamber 221 is disposed in the second portion 223 or in the first portion 222 and the second portion 223. At least a portion of the connecting member 3 passes through the first extension 12 and the second portion 223 to detachably connect the first extension 12 and the second extension 22.

[0048] Specifically, such as Figure 3 As shown, the first part 222 is closer to the body 21 than the second part 223. The first part 222 is arranged at a downward angle, and the free end of the first part 222 is connected to the second part 223. The second part 223 is arranged parallel to the first direction, so that the cross-sectional area of ​​the first part 222 is larger than that of the body 21, which helps to improve the connection between the first part 222 and the body 21, thereby improving the connection between the second extension 22 and the body 21.

[0049] The second part 223 is located below the first extension 12 and overlaps with the first extension 12. The connection between the second extension 22 and the first extension 12 is achieved through the connection between the second part 223 and the first extension 12.

[0050] Optionally, the cross-section of the first part 222 is generally trapezoidal, and the cross-section of the second part 223 is generally rectangular.

[0051] In some embodiments, such as Figure 2 As shown, there are multiple connecting components 3, which are spaced apart along a second direction parallel to the length direction of the frame 1. The arrangement of multiple connecting components 3 spaced apart along the second direction improves the connection stability between the first extension 12 and the second extension 22.

[0052] In some embodiments, such as Figure 3 As shown, the second extension 22 also includes a reinforcing rib 224, which is disposed within the second chamber 221. In this embodiment, by providing the reinforcing rib 224 within the second chamber 221, the structural strength of the second extension 22 is improved.

[0053] Optionally, a reinforcing member may also be provided between the lower end face of the first part 222 of the second extension 22 and the body 21 to further improve the connection strength between the first part 222 and the body 21.

[0054] In some embodiments, such as Figure 2As shown, the main body 21 includes a battery body 211 and a battery management system 212. The battery management system 212 is located above the battery body 211. The frame 1 has an installation space 13. The battery body 211 and the battery management system 212 are located in the installation space 13. The frame 1 has a support member 14, which is located directly above the battery management system 212.

[0055] In this embodiment, the support member 14 is positioned directly above the battery management system 212. The support member 14 supports the mounting components on the vehicle frame 1, preventing the mounting components from directly pressing on the battery management system 212, thus protecting the battery management system 212. Furthermore, by positioning the battery management system 212 above the battery body 211, this embodiment facilitates maintenance of the battery management system 212.

[0056] Optionally, the battery management system 212 and the support member 14 have a gap in the vertical direction.

[0057] For example, the mounting component is a bucket seat.
