Description

Technical Field

[0001] The utility model relates to the technical field of vehicle battery swapping frames, and particularly relates to a battery swapping frame and a vehicle. Background Art

[0002] Battery swapping, as a new energy replenishment method, has received attention. Common battery swapping methods include whole-pack battery swapping and sub-pack battery swapping (also known as chocolate battery swapping). The advantage of sub-pack battery swapping is high freedom and the ability to flexibly match modular batteries with different endurance requirements. In the case of sub-pack battery swapping, an intermediate beam needs to be set to separate the loading areas of different battery packs.

[0003] When a vehicle using this battery swapping frame conducts battery swapping, it is required that the battery be in a horizontal position to enable precise disassembly of the battery. To ensure that the battery is in a horizontal position, during battery swapping, the support mechanism on the battery swapping station side will contact the battery swapping support surface on the side beam and lift the battery swapping frame for adjustment. The weight of the whole vehicle is concentrated at the position where the support mechanism contacts the side beam, which is likely to cause stress concentration and then may cause deformation of the side beam. Summary of the Utility Model

[0004] The purpose of the embodiments of the utility model is to provide a battery swapping frame and a vehicle.

[0005] The embodiments of the utility model adopt the following technical scheme: A battery swapping frame includes a front beam, a rear beam, an intermediate beam, a first side beam, and a second side beam;

[0006] Both ends of the intermediate beam are respectively connected to the first side beam and the second side beam,

[0008] The battery swapping support surface of the battery swapping frame is located at the position where the lower sides of the first side beam and the second side beam in the vehicle height direction overlap with the intermediate beam.

[0014] In some embodiments, the battery swapping frame further includes a battery swapping support plate, which is respectively disposed on the lower surface of the first side beam and the lower surface of the second side beam, and the lower surface of the battery swapping support plate forms the battery swapping support surface.

[0015] In some embodiments, the upper surfaces of both ends of the intermediate beam are fixed to the inner top surface of the first side beam and the inner top surface of the second side beam, respectively, and the lower surfaces of both ends of the intermediate beam are fixed to the inner bottom surface of the first side beam and the inner bottom surface of the second side beam, respectively.

[0016] In some embodiments, the battery swapping support surface is provided with an anti-slip structure.

[0039] For vehicles using battery swapping, swapping methods include full-pack swapping and partial-pack swapping. Partial-pack swapping offers the following advantages over full-pack swapping: greater flexibility, allowing for the matching of modular batteries to meet different range requirements. For example, for vehicles with relatively low range requirements, the energy storage capacity of the modular battery can be slightly smaller to reduce the weight of the swapped battery and thus the overall vehicle weight. Conversely, for vehicles with higher range requirements, a higher energy storage capacity of the modular battery is needed. Partial-pack swapping allows for the flexible replacement of one or more individual batteries within the modular battery pack, according to user needs. For instance, the swapping vehicle may have two independent batteries; depending on the user's requirements, one battery can be replaced, or both batteries can be replaced.

[0040] During battery swapping, the battery must be in a horizontal position with high precision to ensure accurate removal by the battery disassembly mechanism. For example, the battery disassembly mechanism at the swapping station can remove screws securing the battery, which requires the battery to be horizontal so the mechanism can precisely align with and remove the screws. To ensure the battery is horizontal, the support mechanism on the swapping station side contacts the battery swapping support surface located on the side beam and supports the swapping frame for adjustment. The entire vehicle's weight is concentrated at the contact point between the support mechanism and the side beam, which can potentially cause deformation of the side beam and affect the effectiveness of the support mechanism in adjusting the horizontal position of the swapping frame. This can also affect the lifespan of the entire swapping frame and even compromise vehicle safety.

[0041] Having provided the above basic introduction to the battery swapping framework, this application provides a battery swapping framework applicable to vehicles using battery swapping systems. The vehicle may be, but is not limited to, sedans, trucks, SUVs (Sports Utility Vehicles), MPVs (Multi-Purpose Vehicles), buses, and special-purpose vehicles, among which special-purpose vehicles may include ambulances, fire trucks, etc.

[0042] like Figure 1 As shown, the battery swapping frame may include a front beam 1, a rear beam 2, a middle beam 3, a first side beam 4, and a second side beam 5. The front beam 1, first side beam 4, rear beam 2, and second side beam 5 can be sequentially connected to form a rectangular frame, with the central area enclosed by the rectangular frame used to house the battery swapping unit 14. For example, the front beam 1, first side beam 4, rear beam 2, and second side beam 5 can be sequentially connected end-to-end to form a rectangular frame, ensuring that the ends of the front beam 1, first side beam 4, rear beam 2, and second side beam 5 are smooth, or protective components can be provided at the ends of the front beam 1, first side beam 4, rear beam 2, and second side beam 5 to prevent sharp edges from the battery swapping frame and avoid scratches to the vehicle or personnel. The front beam 1 can be understood as being closer to the front of the vehicle, while the rear beam 2 can be understood as being closer to the rear of the vehicle.

[0043] The front beam 1, rear beam 2, middle beam 3, first side beam 4, and second side beam 5 can be made of the same material or different materials. The front beam 1, rear beam 2, middle beam 3, first side beam 4, and second side beam 5 can be set as profile beams to ensure the rigidity of the battery swapping frame while reducing the overall weight of the battery swapping frame, thereby reducing the weight of the entire vehicle.

[0044] For example, since many vehicles need to drive outdoors, they may encounter rain, snow, or wet surfaces. Therefore, stainless steel profiles can be used to make the battery swapping frame to improve its corrosion resistance and thus extend its service life.

[0045] For the subcontracted battery swapping method, this application embodiment takes the example of the support mechanism on the battery swapping station side contacting and supporting the battery swapping support surface 11 located on the first side beam 4 and the second side beam 5 to support the battery swapping frame.

[0046] For example, the two ends of the intermediate beam 3 can be connected to the first side beam 4 and the second side beam 5 respectively, such as... Figure 1 and Figure 2As shown, the first side beam 4 and the second side beam 5 have openings towards the intermediate beam 3 in the cross-section along the vehicle width direction, and partially cover the intermediate beam 3 in the vehicle width direction. Both the first side beam 4 and the second side beam 5 have a cavity structure with an opening on one side, and the cavity structure has an inner top surface, an inner side surface, and an inner bottom surface. The cavity structures of the first side beam 4 and the second side beam 5 can respectively achieve three-sided enclosure of both ends of the intermediate beam 3, including enclosure of the upper surface, outer end surface, and lower surface of the intermediate beam 3. The outer end surface of the intermediate beam 3 can abut against the inner side surface of the cavity structure, or it can not directly contact the inner side surface of the cavity structure, but rather the position of the intermediate beam 3 can be fixed through other fixing structures or limiting structures.

[0047] Furthermore, the battery swapping support surface 11 of the battery swapping frame is located at the position where the first side beam 4 and the second side beam 5 overlap with the intermediate beam 3 on the lower side in the vehicle height direction. That is, the intermediate beam 3 is located between the first side beam 4 and the second side beam 5. For ease of description, the two ends of the intermediate beam 3 are respectively described as the first end and the second end. The first end of the intermediate beam 3 can extend a certain distance from the opening of the first side beam 4 into the first side beam 4 so that the first side beam 4 can cover the first end of the intermediate beam 3. Similarly, the second end of the intermediate beam 3 can extend a certain distance from the opening of the second side beam 5 into the second side beam 5 so that the second side beam 5 can cover the second end of the intermediate beam 3. The first end of the first side beam 4 and the first end of the intermediate beam 3 overlap in a certain area in the vehicle height direction, and the second end of the second side beam 5 and the second end of the intermediate beam 3 overlap in a certain area in the vehicle height direction.

[0048] In this embodiment, the battery swapping support surface 11, which contacts the battery swapping frame on the side of the battery swapping station, is located at a position overlapping the intermediate beam 3 on the lower side of the first side beam 4 and the second side beam 5 in the vehicle height direction. This achieves the following:

[0049] First, the intermediate beam 3 can reinforce the first side beam 4 and the second side beam 5, preventing stress concentration at the contact point between the battery swapping support surface 11 and the support mechanism on the battery swapping side, thus avoiding deformation or damage to the first side beam 4 and / or the second side beam 5. The intermediate beam 3 shares a portion of the load of the first side beam 4 and the second side beam 5, thereby reducing the required section modulus for the first side beam 4 and the second side beam 5 to withstand battery swapping frame buckling. Specifically, battery swapping frame buckling refers to the phenomenon where the battery swapping frame collapses due to its inability to withstand pressure during compression. To enhance the compressive strength of the first side beam 4 and the second side beam 5 in the battery swapping frame, the cross-sectional dimensions of the first side beam 4 and the second side beam 5 at the corresponding positions on the battery swapping support surface 11 are increased. This allows the first side beam 4 and the second side beam 5 to transfer pressure to the intermediate beam 3 through the battery swapping support surface 11, thereby reducing the required section modulus for the first side beam 4 and the second side beam 5.

[0050] Second, the middle beam 3 can also balance the forces on the first side beam 4 and the second side beam 5. For example, when the support mechanism on the side of the battery swapping station horizontally adjusts the battery swapping frame, and the weight of the whole vehicle is concentrated on the battery swapping contact surface corresponding to the first side beam 4 of the support mechanism, the load received by the first side beam 4 can be transmitted to the second side beam 5 through the middle beam 3.

[0051] Third, the first side beam 4 and the second side beam 5 can also share the battery weight borne by the middle beam 3. For example, the battery swapping frame can form two sub-regions to respectively install two battery swapping batteries 14 through the two sub-regions. The middle beam 3 can install the sub-packaged batteries on the battery swapping frame in a front-back distribution form. Two sub-regions on the front and rear sides of the middle beam 3 can respectively place two battery swapping batteries 14. The battery swapping batteries 14 can be fixed on the battery swapping frame through a locking mechanism, and part of the locking mechanisms of the two battery swapping batteries 14 can be arranged on the middle beam 3. Therefore, the weight of the battery swapping batteries 14 will be borne by the middle beam 3. In the embodiment of the present application, the first side beam 4 and the second side beam 5 can also share the battery weight borne by the middle beam 3.

[0052] Specifically, both ends of the middle beam 3 can be clamped and fixed inside the first side beam 4 and the second side beam 5 respectively. For example, the opening sizes of the first side beam 4 and the second side beam 5 are slightly smaller than the thickness size of the middle beam 3 (the dimension of the middle beam 3 in the vehicle height direction), which not only ensures that both ends of the middle beam 3 can extend into the first side beam 4 and the second side beam 5 from the openings of the first side beam 4 and the second side beam 5, but also ensures that both ends of the middle beam 3 can be firmly clamped and fixed inside the first side beam 4 and the second side beam 5. In addition, both ends of the middle beam 3 can also be welded and fixed on the inner surfaces of the first side beam 4 and the second side beam 5 respectively. Of course, it can be understood that other connection methods can also be adopted between the middle beam and the first side beam 4 and the second side beam 5. Only this is used as an example and does not constitute a limitation on the protection scope of the claims.

[0053] In some embodiments, the cross-sections of the first side beam 4 and the second side beam 5 in the vehicle width direction are in a "C" shape, which can also be understood as the cross-sections of the first side beam 4 and the second side beam 5 are in a "C" shape. For example, both the first side beam 4 and the second side beam 5 have a top plate, side plates and a bottom plate, and the top plate, side plates and bottom plate enclose to form a "C" shape. The top plate, side plates and bottom plate can be flat plates or curved plates, etc. For example, the integrated top plate, side plates and bottom plate enclose to form the first side beam 4 and the second side beam 5 with a cross-section of "C" shape.

[0054] Of course, it can be understood that the "C" shape does not limit that the cross-sections of the first side beam 4 and the second side beam 5 in the vehicle width direction are completely in a "C" shape. The cross-sections of the first side beam 4 and the second side beam 5 in the vehicle width direction can also be other shapes, as long as they have an opening that can allow the middle beam 3 to extend into and face the middle beam 3.

[0055] In some embodiments, in order to further improve the strength of the first side beam 4 and the second side beam 5, a strengthening structure 6 may be provided inside the first side beam 4 and the second side beam 5. The strengthening structure 6 may be arranged along the first side beam 4 and the second side beam 5 in the vehicle length direction, or may be arranged only at the positions where the first side beam 4 and the second side beam 5 overlap with the middle beam 3. The strengthening structure 6 may be provided on the inner side surface of the cavity structure, and / or on the inner top surface, and / or on the inner bottom surface. For example, in some feasible embodiments, the strengthening structure 6 is a reinforcing plate with a "U" - shaped cross - section. The reinforcing plate with a "U" - shaped cross - section may be horizontally arranged inside the first side beam 4 and the second side beam 5. As Figure 2 shown, the opening of the reinforcing plate with a "U" - shaped cross - section faces the inner side surfaces of the cavity structures of the first side beam 4 and the second side beam 5. For example, the reinforcing plate with a "U" - shaped cross - section may be welded to the inner side surfaces of the cavity structures of the first side beam 4 and the second side beam 5.

[0056] Based on the above - mentioned strengthening structure 6, a strengthening flat plate 12 may also be provided at the positions where the inner bottom surfaces of the cavity structures of the first side beam 4 and the second side beam 5 correspond to the overlapping part with the middle beam 3. The strengthening flat plate 12 may be welded to the inner bottom surfaces of the cavity structures of the first side beam 4 and the second side beam 5, and the middle beam 3 may be welded and fixed to the strengthening flat plate 12. In this way, on the one hand, the strength of the corresponding positions of the first side beam 4 and the second side beam 5 can be enhanced by the strengthening flat plate 12, and on the other hand, the adverse effect on the strength of the first side beam 4 and the second side beam 5 caused by directly welding the middle beam 3 to the inner bottom surfaces of the cavity structures of the first side beam 4 and the second side beam 5 can be avoided.

[0057] Furthermore, a support member 13 may also be provided inside the first side beam 4 and the second side beam 5. The upper and lower ends of the support member 13 may respectively abut against the inner top surface and the inner bottom surface of the cavity structure, and the cross - section of the support member 13 may be Z - shaped. Among them, the top surface and / or the bottom surface of the support member 13 may overlap with the middle beam 3 in the vehicle height direction, so as to provide a supporting effect for the power - swapping support surface 11 corresponding to the positions of the first side beam 4 and the second side beam 5 through the support member 13.

[0058] In some embodiments, the power - swapping frame further includes a reinforcing member 8 and sleeves 7. The sleeves 7 are symmetrically arranged on the outer sides of the first side beam 4 and the second side beam 5. The two ends of the reinforcing member 8 are respectively connected to the two symmetrically arranged sleeves 7, and the reinforcing member 8 is also respectively connected to the first side beam 4 and the second side beam 5.

[0059] The two ends of the reinforcing member 8 can be respectively fitted onto two symmetrically arranged sleeves 7, or the two ends of the reinforcing member 8 can be respectively welded to two symmetrically arranged sleeves 7. The upper surface of the reinforcing member 8 can also contact the bottom surface of the first side beam 4 and the second side beam 5. For example, the upper surface of the reinforcing member 8 can be welded to the first side beam 4 and the second side beam 5 to further transfer the force balance of the first side beam 4 and the second side beam 5 to the sleeves 7 through the reinforcing member 8. Fixing screws can be provided inside the sleeves 7 to securely connect the battery swapping frame to the vehicle chassis. The sleeves 7 can extend into the corresponding holes in the vehicle chassis, thereby further transferring the load on the first side beam 4 and the second side beam 5 to the vehicle chassis through the sleeves 7.

[0060] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the reinforcing member 8 can be a long strip or a rod. The number of strips or rods can be one or more, depending on the needs; no specific restrictions are imposed here. When there are two or more reinforcing members 8, each reinforcing member 8 can be arranged along the axial direction of the sleeve 7 (e.g., ...). Figure 7 As shown), the various reinforcing members 8 can also be placed in the same plane (e.g., Figure 8 (As shown). In addition, the reinforcing member 8 may be made of materials such as stainless steel.

[0061] For example, taking reinforcement member 8 as a long strip plate, such as Figure 3 As shown, the reinforcing member 8 has a first through hole 801 and a second through hole 802 at both ends. The first through hole 801 and the second through hole 802 can be respectively fitted onto two symmetrically arranged sleeves 7. For example, the reinforcing member 8 can be a long strip plate, with the first through hole 801 and the second through hole 802 respectively provided near both ends of the long strip plate. The shape and size of the first through hole 801 and the second through hole 802 are adapted to the shape of the two symmetrically arranged sleeves 7 so that the sleeves 7 can be securely fastened to the reinforcing member 8, and the load of the first side beam 4 and the second side beam 5 can be transferred to the two symmetrically arranged sleeves 7 through reinforcement.

[0062] Of course, welding can also be performed at the positions where the first through hole 801 and the second through hole 802 contact the outer surface of the sleeve 7.

[0063] When welding the reinforcing member 8, it can be welded in a uniform ring around the center of the first through hole 801 and the center of the second through hole 802 to avoid uneven connection stability between the reinforcing member 8 and the sleeve 7 due to uneven welding, which would affect the effect of the reinforcing member 8 on the balanced transfer of load on the first side beam 4 and the second side beam 5.

[0064] In addition, such as Figure 4 and Figure 5 As shown, the reinforcing member 8 can also be designed with the following structure: the end faces of both ends of the reinforcing member 8 can be arc surfaces that fit with the outer peripheral surface of the sleeve 7, so that the end faces of both ends of the reinforcing member 8 can respectively fit against the outer peripheral surface of the sleeve 7, and the end faces of both ends of the reinforcing member 8 can be respectively welded to the outer peripheral surface of the sleeve 7; in this way, the reinforcing member 8 can form a firm connection with the sleeve 7, and thus the load of the first side beam 4 and the second side beam 5 can be better transferred to the two symmetrically arranged sleeves 7 through the reinforcing member 8.

[0065] The reinforcing member 8 can be located below the intermediate beam 3. The width of the reinforcing member 8 should preferably not exceed the width of the intermediate beam 3 (the size of the intermediate beam 3 in the length direction of the vehicle) to avoid the reinforcing member 8 affecting the installation and removal of the battery swapping unit 14.

[0066] In some embodiments, such as Figure 9 As shown, the two symmetrically arranged sleeves 7 can be a single piece. The single-piece sleeves 7 have a connecting portion 9 that connects the two sleeves 7, and the connecting portion 9 can be used as a reinforcing member 8. The connecting portion 9 can be a long strip or a rod.

[0067] Of course, it is understandable that a reinforcing member 8 can also be additionally provided outside the connecting portion 9 between the integral sleeves 7. Through the combined action of the connecting portion 9 and the reinforcing member 8, the effect of balancing the load on the first side beam 4 and the second side beam 5 onto the sleeve 7 is further improved. The connecting portion 9 can be a connecting plate, for example, such as... Figure 9 As shown, the connecting plate is positioned between the outer circumferential surfaces of the bottom ends of the two symmetrically arranged sleeves 7. Of course, the position of the connecting plate can be set as needed, and no specific restrictions are imposed here.

[0068] The material of the reinforcing member 8 in the above embodiments can be the same as or different from that of the sleeve 7, and can be selected according to actual production needs.

[0069] In some embodiments, the battery swapping frame further includes a battery swapping support plate 10. There may be two battery swapping support plates 10, which are respectively disposed on the lower surface of the reinforcing member 8, and the lower surface of the battery swapping support plate 10 is formed as a battery swapping support surface 11.

[0070] Specifically, when the reinforcing member 8 is a plate-shaped structure, two battery swapping support plates 10 can be welded to the lower surface of the reinforcing member 8 respectively. When the reinforcing member 8 is a rod-shaped structure, multiple rod-shaped reinforcing members 8 can be arranged in the same plane, and two battery swapping support plates 10 can be welded to the lower surface of each rod-shaped reinforcing member 8 respectively.

[0071] One of the battery swapping support plates 10 overlaps with the intermediate beam 3 and the first side beam 4 in the vehicle height direction, while the other battery swapping support plate 10 overlaps with the intermediate beam 3 and the second side beam 5 in the vehicle height direction. The installation of the battery swapping support plates 10 further enhances the strength of the support mechanism on the battery swapping station side and the corresponding positions of the first side beam 4 and the second side beam 5, preventing deformation or damage to the first side beam 4 and the second side beam 5.

[0072] In some embodiments, the battery swapping frame further includes a battery swapping support plate 10. There may be two battery swapping support plates 10, which may be respectively disposed on the lower surface of the first side beam 4 and the lower surface of the second side beam 5, and the lower surface of the battery swapping support plate 10 is formed as a battery swapping support surface 11.

[0073] Unlike the embodiment described above where the battery swapping support plate 10 is mounted on the reinforcing member 8, this embodiment allows the battery swapping support plate 10 to be directly mounted on the lower surface of the first side beam 4 and the lower surface of the second side beam 5.

[0074] Specifically, when the battery swapping support plate 10 is directly set on the lower surface of the first side beam 4 and the lower surface of the second side beam 5, the battery swapping frame may not need to be equipped with the reinforcing member 8, or, a clearance hole may be set at the corresponding position of the reinforcing member 8, and the battery swapping support plate 10 may be set at the corresponding clearance hole.

[0075] In some embodiments, the upper surfaces of both ends of the intermediate beam 3 are fixed to the inner top surfaces of the first side beam 4 and the second side beam 5, respectively, and the lower surfaces of both ends of the intermediate beam 3 are fixed to the inner bottom surfaces of the first side beam 4 and the second side beam 5, respectively. As mentioned above, the two ends of the intermediate beam 3 can be fixed to the first side beam 4 and the second side beam 5 by welding. Here, the upper surfaces of both ends of the intermediate beam 3 are fixed to the inner top surfaces of the first side beam 4 and the second side beam 5, respectively, and the lower surfaces of both ends of the intermediate beam 3 are fixed to the inner bottom surfaces of the first side beam 4 and the second side beam 5, respectively, so that the intermediate beam 3 supports the first side beam 4 and the second side beam 5 in the vehicle height direction, thereby improving the bending resistance of the first side beam 4 and the second side beam 5 and preventing deformation or damage to the first side beam 4 and the second side beam 5.

[0076] Based on the above embodiments, an anti-slip structure can also be provided on the battery swapping support surface 11 to prevent the support structure on the battery swapping station side from sliding against the battery swapping support surface 11 when they come into contact, especially during vehicle leveling adjustments, which could lead to damage to the reversing frame or the vehicle. The anti-slip structure may include, but is not limited to, anti-slip textures.

[0077] In addition, grooves or protrusions can be provided on the battery swapping support surface 11 as needed, so that the grooves or protrusions on the battery swapping support surface 11 can be adapted to the protrusions or grooves on the support mechanism on the side of the battery swapping station. On the one hand, this can play an anti-slip role, and on the other hand, it can also achieve accurate positioning of the battery swapping frame and the support mechanism.

[0078] This application also provides a vehicle including a battery swapping frame as described in any of the above embodiments.

[0079] When a vehicle using the battery swapping frame described in the above embodiments undergoes battery swapping, the intermediate beam 3 can share the weight of the entire vehicle, reducing the load on the first side beam 4 and the second side beam 5. This solves the problem of deformation of the first side beam 4 when the support mechanism only supports the first side beam 4 and the second side beam 5. Simultaneously, the first side beam 4 and the second side beam 5 can also share the battery weight borne by the intermediate beam 3. This avoids frequent replacement of vehicle parts and prevents safety hazards caused by deformation or damage to the battery swapping frame structure.

[0080] Vehicles can be, but are not limited to, sedans, trucks, SUVs (sports utility vehicles), MPVs (multi-purpose commercial vehicles), buses, and special-purpose vehicles, among which special-purpose vehicles can be ambulances, fire trucks, etc.

[0081] The foregoing has described in detail several embodiments of the present utility model, but the present utility model is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of the present utility model, and these variations and modifications should all fall within the scope of protection claimed by the present utility model.
