[0026] In the prior art, when replacing the power battery, the electric vehicle needs to be lifted so that workers can access the bottom of the vehicle for replacement. However, before lifting the vehicle, it is necessary to find a suitable lifting point under the vehicle body, which is a time-consuming process and results in low battery replacement efficiency.

[0027] In view of the problems existing in the above-mentioned related technologies, the utility model provides a vehicle body lifting bracket mounting structure and a vehicle.

[0028] Combine Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a vehicle body lifting bracket mounting structure, comprising a rocker inner panel 1, a rocker inner panel reinforcement plate 3 and a lifting bracket 2 arranged at the bottom of the rocker inner panel 1, the upper end of the rocker inner panel reinforcement plate 3 is connected to the rocker inner panel 1, the lifting bracket 2 comprises a first connecting portion 21, a second connecting portion 22 and a supporting portion 23, the first connecting portion 21 is arranged above the second connecting portion 22 and is connected to one end of the second connecting portion 22, the supporting portion 23 is horizontally arranged below the second connecting portion 22 and is connected to the other end of the second connecting portion 22, and the first connecting portion 21 and the second connecting portion 22 are respectively connected to the rocker inner panel 1 and the rocker inner panel reinforcement plate 3.

[0029] Specifically, the rocker inner panel 1 and the rocker inner panel reinforcement plate 3 are generally in a long strip structure and extend in the front-to-back direction of the vehicle (i.e. Figure 1 The sill inner panel 1 is arranged in the direction of the middle X-axis, and the lifting bracket 2 is provided at the bottom of the sill inner panel 1, and there are usually multiple lifting brackets 2. For example, a lifting bracket 2 can be provided at the front and rear ends of the left sill inner panel 11 and the front and rear ends of the right sill inner panel 12, so as to use four lifting brackets 2 to provide four lifting points. Alternatively, three lifting brackets 2 can be provided on each of the left sill inner panel 11 and the right sill inner panel 12, so as to use six lifting brackets 2 to provide six lifting points. When it is necessary to lift the vehicle body for battery replacement or after-sales maintenance, multiple lifting devices can be supported on multiple lifting brackets 2 respectively and lifted simultaneously, so that the balance of the vehicle body can be adjusted by the lifting brackets 2 to ensure the normal progress of battery replacement or after-sales maintenance.

[0030] More specifically, the lifting bracket 2 includes a first connecting portion 21, a second connecting portion 22, and a horizontally arranged supporting portion 23, which are arranged in sequence from top to bottom. The first connecting portion 21, the second connecting portion 22, and the supporting portion 23 can all be plate-shaped structures. Moreover, the first connecting portion 21 and the supporting portion 23 are integrally connected by the second connecting portion 22 located between the first connecting portion 21 and the supporting portion 23. The entire lifting bracket 2 can be an integral sheet metal part or casting. When the two ends of the second connecting portion 22 are respectively connected to the ends of the first connecting portion 21 and the supporting portion 23, for example Figure 2 As shown, the lift bracket 2 has a generally U-shaped structure, with its opening facing horizontally inward from the vehicle body. When the ends of the second connecting portion 22 are connected to the middle of the first connecting portion 21 and the support portion 23, the lift bracket 2 generally forms an I-shaped structure. When the ends of the second connecting portion 22 are connected to the ends of the first connecting portion 21 and the middle of the support portion 23, the lift bracket 2 generally forms a Z-shaped structure. Simultaneously, the first connecting portion 21 and the second connecting portion 22 are connected to the rocker inner panel 1 and the rocker inner panel reinforcement plate 3, respectively. This secures the lift bracket 2 to the rocker inner panel 1 and the rocker inner panel reinforcement plate 3, while the lifting device abuts against the horizontal support portion 23 to maintain vehicle body balance. The connections between the first connecting portion 21 and the rocker inner panel 1, and between the second connecting portion 22 and the rocker inner panel reinforcement plate 3, can be removable, such as bolts or clamps, or non-removable, such as welding, without specific limitation.

[0031] The vehicle body lift bracket mounting structure of this embodiment can be configured by disposing a lift bracket 2 at the bottom of the rocker inner panel 1. This lift bracket 2 can be used as a lifting point to lift the vehicle, facilitating battery replacement or after-sales repairs. This eliminates the need to find a separate lifting point under the vehicle body, effectively shortening the battery replacement or repair process and improving efficiency. Furthermore, by configuring the lift bracket 2 to include a first connecting portion 21, a second connecting portion 22, and a support portion 23, sequentially connected from top to bottom, the first connecting portion 21 and the second connecting portion 22 are connected to the rocker inner panel 1 and the rocker inner panel reinforcement plate 3, respectively, to stably secure the lift bracket 2 to the vehicle body rocker beam. Furthermore, the first connecting portion 21 and the second connecting portion 22 can transmit the lifting force upward through the rocker inner panel 1 and the rocker inner panel reinforcement plate 3, respectively, ensuring uniform force on the vehicle body rocker beam and improving support effectiveness. Furthermore, by disposing the support portion 23 horizontally, the lifting equipment can abut against the support portion 23 to support the lift bracket 2, thereby ensuring vehicle body balance during lifting.

[0032] Optionally, combined Figure 1As shown, the rocker inner panel 1 includes a left rocker inner panel 11 and a right rocker inner panel 12 , and a lifting bracket 2 is respectively provided at both ends of the left rocker inner panel 11 and the right rocker inner panel 12 .

[0033] In this optional embodiment, the rocker inner panel 1 is generally in a long strip structure and extends along the front-to-back direction of the vehicle (i.e. Figure 1 The sill inner panel 1 includes a left sill inner panel 11 and a right sill inner panel 12, which are respectively arranged at the left and right ends of the vehicle body floor 100 (i.e., the vehicle body floor 100 is located at Figure 1 The lifting brackets 2 are located at the bottom of the rocker panel 1, typically at the front and rear ends. Specifically, a lifting bracket 2 is provided at each of the front and rear ends of the left rocker panel 11 and the right rocker panel 12. This ensures that four lifting brackets 2 are evenly distributed across the entire vehicle body. During battery replacement, the four lifting brackets 2 can be simultaneously raised using a lifting device to ensure vehicle balance, facilitating rapid battery replacement.

[0034] Optionally, combined Figure 2 As shown, the rocker inner panel reinforcement plate 3 includes a bottom plate 31 and a folded edge 32 extending downward from the outer edge of the bottom plate 31 , the rocker inner panel 1 is connected to the bottom plate 31 , the second connecting portion 22 is connected to the folded edge 32 , and the support portion 23 is located below the folded edge 32 .

[0035] In this alternative embodiment, the rocker inner panel reinforcement 3 comprises a base plate 31 and a folded edge 32. The base plate 31 is generally horizontal, with the folded edge 32 extending downward from the outer edge of the base plate 31 (i.e., the edge of the base plate 31 facing outward from the vehicle). The second connecting portion 22 connects to the folded edge 32 of the rocker inner panel reinforcement 3 to achieve connection. Furthermore, by positioning the support portion 23 below the folded edge 32, the lower end of the lift bracket 2 extends beyond the lower end of the rocker inner panel reinforcement 3. This prevents interference between the lifting equipment and the rocker inner panel reinforcement 3 during the lifting operation at the lift bracket 2, thereby facilitating lifting.

[0036] Optionally, combined Figure 2 As shown, the support portion 23 includes a first support segment 231 and a second support segment 232 connected to each other, the second connecting portion 22 is connected to one end of the first support segment 231 close to the second support segment 232, and the second support segment 232 is located on the side of the second connecting portion 22 close to the folded edge 32 and abuts against the lower edge of the folded edge 32.

[0037] In this optional embodiment, the sill inner panel 1 and the sill inner panel reinforcement plate 3 are components of the sill beam, and a sill beam is provided on each of the left and right sides of the vehicle body. For the lifting bracket 2 arranged on the left sill beam, the left side of the second connection part 22 is close to the folding edge 32 of the sill inner panel reinforcement plate 3, and the right side is away from the folding edge 32. At this time, the side of the second connection part 22 close to the folding edge 32 refers to the left side of the second connection part 22, that is, the second support section 232 is located on the left side of the second connection part 22; for the lifting bracket 2 arranged on the right sill beam, the left side of the second connection part 22 is away from the folding edge 32, and the right side is close to the folding edge 32. At this time, the side of the second connection part 22 close to the folding edge 32 refers to the right side of the second connection part 22, that is, the second support section 232 is located on the right side of the second connection part 22.

[0038] In this way, by connecting the second connecting portion 22 to the end of the first supporting section 231 of the supporting portion 23 close to the second supporting section 232, which is equivalent to the second connecting portion 22 being connected to the connection between the first supporting section 231 and the second supporting section 232, the force on the entire supporting portion 23 can be uniform, which is conducive to the upward transmission of the lifting force. The second supporting section 232 is set on the side of the second connecting portion 22 close to the folded edge 32 and abuts against the lower edge of the folded edge 32, so that the outer end surface of the supporting portion 23 (that is, the side of the supporting portion 23 facing the outside of the vehicle) The side of the second connecting portion 22 extends beyond the outer end surface of the second connecting portion 22 (i.e., the side of the second connecting portion 22 facing the outside of the vehicle), and the portion of the supporting portion 23 extending beyond the second connecting portion 22 (i.e., the second supporting segment 232) abuts against the lower edge of the folding edge 32, thereby transmitting the lifting force received by the supporting portion 23 to the rocker inner panel reinforcement plate 3 through the folding edge 32, and further transmitting it to the vehicle body, thereby increasing the transmission path for the lifting force to be transmitted to the vehicle body, making the force on the entire vehicle body more evenly distributed during the lifting process, and making it easier to achieve vehicle body balance.

[0039] Optionally, combined Figure 3 As shown, the lifting bracket 2 further includes a supporting rib 24 , which is disposed on a side of the second connecting portion 22 away from the rocker inner panel reinforcement plate 3 and extends from the first connecting portion 21 through the second connecting portion 22 to the supporting portion 23 .

[0040] In this alternative embodiment, the support rib 24 typically extends sequentially along the surfaces of the first connecting portion 21, the second connecting portion 22, and the first support segment 231, from the end of the first connecting portion 21 distal from the second connecting portion 22 to the end of the first support segment 231 distal from the second support segment 232. This improves the overall rigidity of the lift bracket 2, ensuring normal operation and extending the service life of the lift bracket 2. Furthermore, positioning the support rib 24 on the side of the second connecting portion 22 distal from the folded edge 32 prevents interference with the rocker inner panel reinforcement 3 while allowing the second connecting portion 22 to mate with the folded edge 32 of the rocker inner panel reinforcement 3, thereby ensuring a secure connection between the second connecting portion 22 and the rocker inner panel reinforcement 3. Furthermore, multiple support ribs 24 are typically provided, and these ribs are spaced apart to further enhance the rigidity of the lift bracket 2 while ensuring uniform rigidity distribution.

[0041] Optionally, combined Figure 2 and Figure 3 As shown, the second connecting portion 22 includes a first connecting segment 221 and a second connecting segment 222 connected in sequence from one end to the other end. The first connecting segment 221 is connected to one end of the first connecting portion 21 and forms an obtuse angle with the first connecting portion 21. The second connecting segment 222 is vertically connected to the supporting portion 23.

[0042] In this alternative embodiment, the second connecting portion 22 includes an inclined portion (i.e., a first connecting segment 221) connected to the first connecting portion 21 and a perpendicular portion (i.e., a second connecting segment 222) connected to the support portion 23. Furthermore, the first connecting segment 221 forms an obtuse angle with the first connecting portion 21, giving the second connecting portion 22 an overall bent plate-like structure. This not only improves the rigidity of the second connecting portion 22 but also facilitates the use of the inclined first connecting segment 221 to avoid the rocker inner panel reinforcement plate 3, ensuring that the second connecting portion 22 of the lift bracket 2 can be properly installed on the rocker inner panel reinforcement plate 3.

[0043] Further, combined with Figure 2 As shown, the thickness of the first connecting portion 21 and the thickness of the second connecting portion 22 are both less than the thickness of the support portion 23. In this way, by thickening the support portion 23 of the lifting bracket 2, the structural strength of the lifting bracket 2 at the support portion 23 is improved, thereby preventing the support portion 23 from undergoing significant deformation when lifting a vehicle body, thereby ensuring that the lifting bracket 2 can be lifted normally.

[0044] Optionally, combined Figure 2 As shown, the first connecting portion 21 and the second connecting portion 22 are detachably connected to the rocker inner panel 1 and the folding edge 32 via a first fastener 5 and a second fastener 6 respectively.

[0045] In this optional embodiment, the first fastener 5 and the second fastener 6 are usually bolts, that is, the first connection portion 21 and the sill inner panel 1, as well as the second connection portion 22 and the folded edge 32, are connected by bolts to achieve a detachable connection to facilitate assembly and disassembly. Since the distances between the various vehicle body lifting points may be different for different types of electric vehicles, this embodiment arranges the first connection portion 21 and the sill inner panel 1 to be detachably connected via the first fastener 5, and the second connection portion 22 and the folded edge 32 to be detachably connected via the second fastener 6, so that the lifting bracket 2 can be applied to different electric vehicle models, thereby making the lifting bracket 2 universally applicable among different electric vehicle models, thereby reducing the development of different battery swap station tooling to match different lifting brackets 2, saving battery swap costs. In addition, when multiple groups of mounting holes for installing the lifting bracket 2 are provided on the rocker inner panel 1 and the rocker inner panel reinforcement plate 3, the installation position of the lifting bracket 2 can be flexibly adjusted by replacing the lifting bracket 2 to different mounting holes for fixing, thereby adjusting the lifting point position of the vehicle body to facilitate fast and accurate battery replacement.

[0046] Optionally, combined Figure 2 As shown, the first fastener 5 passes through the first connecting portion 21 , the rocker inner panel 1 and the bottom plate 31 of the rocker inner panel reinforcement plate 3 in sequence.

[0047] In this alternative embodiment, the portion of the rocker inner panel 1 that connects to the first connecting portion 21 is located at the joint between the rocker inner panel 1 and the bottom plate 31 of the rocker inner panel reinforcement plate 3. During assembly, the first fastener 5 is sequentially passed through the first connecting portion 21, the rocker inner panel 1, and the bottom plate 31 of the rocker inner panel reinforcement plate 3 to connect the first connecting portion 21, the rocker inner panel 1, and the rocker inner panel reinforcement plate 3. This not only allows the rocker inner panel reinforcement plate 3 to enhance the structural strength of the connection between the vehicle body and the lift bracket 2, but also allows the lifting force to be transmitted to the rocker inner panel reinforcement plate 3 via the rocker inner panel 1, ensuring a more uniform force on the vehicle body.

[0048] Optionally, combined Figure 2 As shown, the vehicle body lifting bracket mounting structure also includes a side inner panel 4, which is located on the side of the folded edge 32 of the rocker inner panel 1 away from the second connecting portion 22, and the second fastener 6 passes through the second connecting portion 22, the folded edge 32 and the side inner panel 4 in sequence.

[0049] In this alternative embodiment, the side inner panel 4 generally includes a left side inner panel 41 and a right side inner panel 42. The left side inner panel 41 is connected to the outer side of the left sill inner panel 11, and the right side inner panel 42 is connected to the outer side of the right sill inner panel 12. For ease of description, the side inner panels 4 are collectively referred to as the left and right side inner panels 41, 42, and the sill inner panels 1 are collectively referred to as the left and right sill inner panels 11, 12. The portion of the sill inner panel reinforcement plate 3 that connects to the second connecting portion 22 is located at the overlap between the folded edge 32 of the sill inner panel reinforcement plate 3 and the side inner panel 4. During assembly, the second fastener 6 is sequentially passed through the second connecting portion 22, the folded edge 32 of the sill inner panel reinforcement plate 3, and the side inner panel 4 to connect the second connecting portion 22, the sill inner panel reinforcement plate 3, and the side inner panel 4. In this way, not only can the side inner panel 4 be used to improve the structural strength of the connection between the vehicle body and the lifting bracket 2, but the lifting force can also be transmitted to the side inner panel 4 through the rocker inner panel reinforcement plate 3, ensuring that the vehicle body is subjected to more uniform force.

[0050] An embodiment of the present invention provides a vehicle, comprising the vehicle body lifting bracket mounting structure as described above.

[0051] The beneficial effects of the vehicle of this embodiment compared to the prior art are the same as those of the above-mentioned vehicle body lifting bracket installation structure, and will not be repeated here.

[0052] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
