DETAILED DESCRIPTION

[0033] The various aspects and features of the present application are described herein with reference to the accompanying drawings.

[0034] It should be understood that various modifications can be made to the embodiments described herein. Therefore, the above description should not be construed as limiting, but merely as an example. Those skilled in the art will conceive other modifications within the scope and spirit of the present application.

[0035] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the present application and serve to explain the principles of the present application together with the general description of the present application given above and the detailed description of the embodiments given below.

[0036] These and other characteristics of the present application will become patently apparent as the description proceeds in conjunction with the accompanying drawings, in which:

[0037] It should also be understood that, although the present application has been described in relation to certain specific examples, many other equivalent forms of which will be apparent to those who are skilled in the art.

[0038] The above and other aspects, features and advantages of the present application will become more apparent from the following detailed description, taken in conjunction with the accompanying drawings, which illustrate by way of example the principles of the application.

[0039] Specific embodiments of the present application are described hereinafter, by way of example only, with reference to the accompanying drawings. It should be understood that the disclosed embodiments are merely representative of the application, which can be practiced in a variety of ways. Well-known and / or redundant functions and structures have not been described in detail in order to avoid obscuring the application unnecessarily. Accordingly, the detailed description provided herein is intended to be illustrative, but not limiting, of the scope of the application. The detailed description set forth hereinafter illustrates by way of example the presently proposed best mode for putting the application into practice.

[0040] This description can use the phrases "in an embodiment," "in another embodiment," "in yet another embodiment," or "in at least one embodiment" which can refer to one or more embodiments of the application.

[0041] For vehicles using battery swap, the battery swap mode includes whole-pack battery swap and sub-pack battery swap. The sub-pack battery swap has the following advantages compared with the whole-pack battery swap: higher degree of freedom, and flexible matching of modular batteries with different endurance requirements. For example, for vehicles with relatively low endurance requirements, the storage capacity of the modular battery can be slightly smaller to reduce the weight of the battery swap battery, thereby reducing the weight of the whole vehicle. For vehicles with relatively high endurance requirements, the storage capacity of the modular battery is also required to be higher. The sub-pack battery swap can flexibly replace one or more sub-pack batteries in the modular battery according to user requirements. For example, two independent batteries are placed on the battery swap frame, and according to user requirements, one of the two batteries can be replaced, or both of the two batteries can be replaced.

[0042] The battery swapping battery can be connected with the battery swapping frame through the locking mechanism 13 to fix the battery swapping battery on the battery swapping frame. For example, each battery swapping battery can be fixedly connected with the battery swapping frame through four locking mechanisms 13, wherein two locking mechanisms 13 of each battery swapping battery can be arranged on the middle beam. In this case, the accelerations at the plurality of locking mechanisms 13 can be different during the driving of the vehicle, especially when the vehicle encounters bumps, or turns, or suddenly accelerates, or suddenly brakes, and the impact forces of the different locking mechanisms 13 on the middle beam and the impact forces at the connection between the locking mechanisms 13 and the middle beam can be different, causing uneven stress on the middle beam, and further causing the middle beam to be deformed or damaged, thereby affecting the service life of the entire battery swapping frame, and even affecting the safety of the vehicle.

[0043] For the above problems, if the rigidity of the middle beam is simply improved, for example, by replacing the material of the middle beam to improve the rigidity of the middle beam, on the one hand, the manufacturing cost of the battery swapping frame is increased, and more importantly, the uneven stress is transmitted to the fastening connection between the battery swapping frame and the vehicle chassis, thereby affecting the strength of the fastening connection.

[0044] After the above basic introduction of the battery swapping frame, the application provides a battery swapping frame applied to a vehicle using a battery swapping battery. The vehicle can be but is not limited to a car, a truck, an SUV (Sport Utility Vehicle), an MPV (Multi-Purpose Vehicle), a bus, and a special-purpose vehicle, etc., wherein the special-purpose vehicle can be an ambulance, a fire truck, etc.

[0045] As shown in Figure 1 and Figure 2 , the battery swapping frame comprises 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, the first side beam 4, the rear beam 2, and the second side beam 5 can be sequentially connected to form a rectangular frame, and the middle region enclosed by the rectangular frame is used to place the battery swapping battery 12. For example, the front beam 1, the first side beam 4, the rear beam 2, and the second side beam 5 can be sequentially connected end to end to form a rectangular frame, and the end portions of the front beam 1, the first side beam 4, the rear beam 2, and the second side beam 5 can be kept smooth or protective members can be arranged at the end portions of the front beam 1, the first side beam 4, the rear beam 2, and the second side beam 5 to avoid the edges of the battery swapping frame having sharp corners, etc., so as to avoid scratches on the vehicle or personnel caused by the sharp corners of the battery swapping frame.

[0046] The front beam 1 can be understood as being closer to the front position of the vehicle, and the rear beam 2 can be understood as being closer to the rear position of the vehicle. It should be noted that the placement direction of the battery swapping frame on the vehicle can not be strictly according to the above front and rear directions, and the placement direction of the battery swapping frame on the vehicle can also be moderately inclined, which can be placed according to the design requirements of the vehicle.

[0047] The front beam 1, the rear beam 2, the middle beam 3, the first side beam 4, and the second side beam 5 can be made of the same material or different materials. The front beam 1, the rear beam 2, the middle beam 3, the first side beam 4, and the second side beam 5 can be in the form of a profiled beam, which can ensure the rigidity of the battery replacement frame and reduce the overall weight of the battery replacement frame, thereby reducing the overall weight of the vehicle.

[0048] For example, many vehicles need to travel outdoors and may encounter rainy and snowy weather or travel on wet ground. Therefore, the battery replacement frame can be made of stainless steel profiles to improve the corrosion resistance of the battery replacement frame and thereby improve the service life of the battery replacement frame.

[0049] For the battery replacement mode of partial battery replacement, the battery replacement frame can accommodate two battery replacement batteries 12, and the battery replacement frame can form two sub-areas to install two battery replacement batteries 12 respectively. Specifically, the middle beam 3 can divide the middle area formed by the above-mentioned rectangular frame into two sub-areas to place two battery replacement batteries 12 respectively.

[0050] For example, the two ends of the middle beam 3 can be connected to the first side beam 4 and the second side beam 5 respectively, or the two ends of the middle beam 3 can be connected to the front beam 1 and the rear beam 2 respectively.

[0051] In some embodiments, when the two ends of the middle beam 3 are connected to the first side beam 4 and the second side beam 5 respectively, the partial battery can be installed on the battery replacement frame in the front-rear distribution form. Specifically, the two ends of the middle beam 3 can be welded and fixed to the inner surfaces of the first side beam 4 and the second side beam 5 respectively. Of course, it can be understood that the middle beam 3, the first side beam 4, and the second side beam 5 can also use other connection methods, which are only used as examples and do not limit the protection scope of the claims.

[0052] For example, the middle region enclosed by the above-mentioned rectangular frame can be divided into a first sub-region and a second sub-region, the first sub-region being enclosed by the front beam 1, the first side beam 4 (a part of the first side beam 4), the middle beam 3, and the second side beam 5 (a part of the second side beam 5), and the second sub-region being enclosed by the rear beam 2, the first side beam 4 (another part of the first side beam 4), the middle beam 3, and the second side beam 5 (another part of the second side beam 5). When the two battery replacement batteries 12 are of the same shape and size, the middle beam 3 can evenly divide the middle region enclosed by the above-mentioned rectangular frame, and when the two battery replacement batteries 12 are of different shapes or sizes, the first sub-region and the second sub-region can also be different. That is, the shape and size of the first sub-region are adapted to the shape and size of one of the two battery replacement batteries 12, and the shape and size of the second sub-region are adapted to the shape and size of the other of the two battery replacement batteries 12, so that both of the two battery replacement batteries 12 can be well installed on the battery replacement frame.

[0053] Similarly, in some embodiments, the two ends of the middle beam 3 can be connected to the front beam 1 and the rear beam 2 respectively, and the battery replacement batteries can be installed on the battery replacement frame in a left-right distributed manner. Specifically, the two ends of the middle beam 3 can be welded and fixed to the inner surfaces of the front beam 1 and the rear beam 2 respectively. Of course, it can be understood that the middle beam 3 and the front beam 1 and the rear beam 2 can also adopt other connection modes, which are only taken as examples and do not constitute a limitation on the scope of protection of the claims.

[0054] For example, the middle region enclosed by the above-mentioned rectangular frame can be divided into a third sub-region and a fourth sub-region, the third sub-region being enclosed by the front beam 1 (a part of the front beam 1), the first side beam 4, the rear beam 2 (a part of the rear beam 2), and the middle beam 3, and the fourth sub-region being enclosed by the rear beam 2 (another part of the rear beam 2), the second side beam 5, the front beam 1 (another part of the front beam 1), and the middle beam 3. Similarly, when the two battery replacement batteries 12 are of the same shape and size, the middle beam 3 can evenly divide the middle region enclosed by the above-mentioned rectangular frame, and when the two battery replacement batteries 12 are of different shapes or sizes, the third sub-region and the fourth sub-region can also be different. That is, the shape and size of the third sub-region are adapted to the shape and size of one of the two battery replacement batteries 12, and the shape and size of the fourth sub-region are adapted to the shape and size of the other of the two battery replacement batteries 12, so that both of the two battery replacement batteries 12 can be well installed on the battery replacement frame.

[0055] Of course, it can be understood that the battery replacement frame can also accommodate multiple (greater than or equal to three) battery replacement batteries 12, in which case the battery replacement frame can correspondingly set the number of middle beams 3 according to the number of battery replacement batteries 12 to divide the middle area enclosed by the front beam 1, the first side beam 4, the rear beam 2 and the second side beam 5 into sub-areas corresponding to the number of battery replacement batteries 12, and install multiple battery replacement batteries 12 in the corresponding sub-areas.

[0056] In addition, a vehicle can be provided with only one battery replacement frame, or two or more battery replacement frames according to the needs of the vehicle. Specifically, it can be set according to the needs of the vehicle and the user.

[0057] The first sleeve 6 and the second sleeve 7 for fastening and connecting the vehicle chassis are provided on the middle beam 3, and the first sleeve 6 and the second sleeve 7 can be provided at a certain distance on the middle beam 3. For example, the first sleeve 6 and the second sleeve 7 can be symmetrically provided on the middle beam 3, and preferably, the first sleeve 6 and the second sleeve 7 can be provided on the first straight line, wherein the direction of the first straight line is the length direction of the middle beam 3, so that the first sleeve 6 and the second sleeve 7 can as much as possible evenly transmit the stress of the middle beam 3 to the vehicle chassis.

[0058] In addition, in order to more evenly transmit the stress of the middle beam 3, the first sleeve 6 and the second sleeve 7 can be respectively arranged at the positions of the three equal division points of the middle beam 3, for example, the middle beam 3 can be divided into three parts of the same length by two three equal division points, and the first sleeve 6 and the second sleeve 7 are respectively arranged at the positions of the two three equal division points of the middle beam 3.

[0059] Of course, it can be understood that the number of first sleeves 6 and the number of second sleeves 7 can not be one, and the number of first sleeves 6 can be two or more, and the number of second sleeves 7 can be two or more.

[0060] A reinforcing member 8 is arranged between the first sleeve 6 and the second sleeve 7 to balance the stress of the first sleeve 6 and the second sleeve 7, and avoid uneven stress at the connection between the middle beam 3 and the first sleeve 6 or the second sleeve 7. That is, the reinforcing member 8 can balance the force between the first sleeve 6 and the second sleeve 7, and at the same time realize the reinforcement and support of the first sleeve 6 and the second sleeve 7, which is beneficial to further improve the stress uniformity of the connection between the middle beam 3 and the first sleeve 6 and the second sleeve 7.

[0061] In the embodiment in which the number of the first sleeves 6 and the number of the second sleeves 7 are both two or more, and the first sleeves 6 and the second sleeves 7 are arranged at intervals, that is, one second sleeve 7 is arranged between two first sleeves 6, or one first sleeve 6 is arranged between two second sleeves 7, the reinforcing member 8 can be arranged between the first sleeves 6 and the second sleeves 7. If the middle beam 3 is divided into two parts of equal length, and two or more first sleeves 6 are arranged on one part of the middle beam 3, and two or more second sleeves 7 are arranged on the other part of the middle beam 3, the reinforcing member 8 can also be arranged between the two first sleeves 6 adjacent to each other and between the two second sleeves 7 adjacent to each other.

[0062] In order to make the stress of the middle beam 3 more uniform, in the case where the number of the first sleeves 6 and the number of the second sleeves 7 are both multiple, the first sleeves 6 and the second sleeves 7 can be arranged in a symmetrical manner or in a uniform manner on the middle beam 3.

[0063] The embodiment of the present application can improve the rigidity of the middle beam 3 while making the stress of the middle beam 3 uniformly distributed to the fastening connection between the battery replacement frame and the vehicle chassis, balance the load generated at the connection between the battery replacement frame and the vehicle chassis by different battery replacement batteries 12 through the first sleeves 6 and the second sleeves 7 and the reinforcing member 8, and thus ensure the strength requirement of the battery replacement frame itself and the fastening connection between the battery replacement frame and the vehicle chassis.

[0064] In some embodiments, as shown in Figure 4 The two ends of the reinforcing member 8 are respectively provided with a first through hole 801 and a second through hole 802, the first through hole 801 is sleeved on the first sleeve 6, and the second through hole 802 is sleeved on the second sleeve 7. For example, the reinforcing member 8 can be a long strip plate, the first through hole 801 and the second through hole 802 are respectively arranged at positions close to the two ends of the long strip plate, the shape and size of the first through hole 801 are adapted to the shape of the first sleeve 6, and the shape and size of the second through hole 802 are adapted to the shape of the second sleeve 7, so that the first sleeve 6 and the second sleeve 7 can be tightly clamped on the reinforcing member 8 and can uniformly transmit the stress of the first sleeve 6 and the second sleeve 7 to the reinforcing member 8.

[0065] Of course, the first through hole 801 and the outer surface of the first sleeve 6 can be welded at the position where they are in contact, and the second through hole 802 and the outer surface of the second sleeve 7 can be welded at the position where they are in contact, so that the reinforcing member 8 can form a firm connection relationship with the first sleeve 6 and the second sleeve 7, thereby ensuring the balancing effect of the reinforcing member 8 on the force between the first sleeve 6 and the second sleeve 7, and further improving the stress uniformity of the connection between the middle beam 3 and the first sleeve 6 and the second sleeve 7.

[0066] When welding the reinforcing member 8, a uniform circumferential welding can be performed around the center of the first through hole 801 and the center of the second through hole 802 to avoid uneven welding causing uneven connection stability between the reinforcing member 8 and the first sleeve 6 and the second sleeve 7, thereby affecting the balance of force on the first sleeve 6 and the second sleeve 7 by the reinforcing member 8.

[0067] In addition, the reinforcing member 8 can also be designed with reinforcing ribs on the long strip to further improve the rigidity of the reinforcing member 8.

[0068] In some embodiments, the two ends of the reinforcing member 8 are welded to the first sleeve 6 and the second sleeve 7, respectively. For example... Figure 5 , Figure 6 and Figure 7 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 first sleeve 6 and the second sleeve 7 (e.g., ...). Figure 8 As shown), the various reinforcing members 8 can also be placed in the same plane (e.g., Figure 9 (As shown). In addition, the reinforcing member 8 may be made of materials such as stainless steel.

[0069] For example, taking reinforcement member 8 as a long strip plate, such as Figure 7 and Figure 8 As shown, the end faces of the reinforcing member 8 can be adapted to the outer peripheral surfaces of the first sleeve 6 and the second sleeve 7, so that the end faces of the reinforcing member 8 can respectively fit against the outer peripheral surfaces of the first sleeve 6 and the second sleeve 7, and the end faces of the reinforcing member 8 can respectively be on the outer peripheral surfaces of the first sleeve 6 and the second sleeve 7; in this way, the reinforcing member 8 can form a firm connection with the first sleeve 6 and the second sleeve 7, and thus better balance the load on the first sleeve 6 and the second sleeve 7 through the reinforcing member 8.

[0070] In some embodiments, such as Figure 10 As shown, the first sleeve 6 and the second sleeve 7 are integrally formed. The integral first sleeve 6 and the second sleeve 7 have a connecting portion 9 that connects them, and the connecting portion 9 can be used as a reinforcing member 8. The connecting portion 9 can be a strip or a rod.

[0071] Of course, it is understandable that the aforementioned reinforcing member 8 can also be provided between the integrated first sleeve 6 and second sleeve 7. Through the combined action of the connecting part 9 and the reinforcing member 8, the load balancing effect at the first sleeve 6 and second sleeve 7 is further improved. The connecting part 9 can be a connecting plate, for example, as... Figure 10As shown, the connecting plate is arranged between the outer circumferential surface of the bottom end of the first sleeve 6 and the outer circumferential surface of the bottom end of the second sleeve 7. Of course, the position of the connecting plate can also be arranged as needed, which is not specifically limited here.

[0072] The material of the reinforcing member 8 in the above embodiment can be the same as or different from the materials of the first sleeve 6 and the second sleeve 7, which can be selected according to actual production needs.

[0073] In some embodiments, the battery replacement frame further comprises a first fastening bolt and a second fastening bolt, the first fastening bolt is fastened and connected with the vehicle chassis through the first sleeve 6; the second fastening bolt is fastened and connected with the vehicle chassis through the second sleeve 7.

[0074] For example, the vehicle chassis is provided with threaded holes at positions corresponding to the first sleeve 6 and the second sleeve 7. For the convenience of description, the vehicle chassis is provided with a first threaded hole at a position corresponding to the position of the first sleeve 6, and a second threaded hole at a position corresponding to the position of the second sleeve 7. The shank of the first fastening bolt is connected with the first threaded hole of the vehicle chassis after passing through the first sleeve 6, and the shank of the second fastening bolt is connected with the second threaded hole of the vehicle chassis after passing through the second sleeve 7. The head of the first fastening bolt and the head of the second bolt can abut on the first sleeve 6 and the second sleeve 7 respectively, so as to fasten and connect the middle beam 3 of the battery replacement frame to the vehicle chassis through the first fastening bolt and the second fastening bolt, and then when the middle beam 3 is impacted by different loads from the two battery replacement batteries 12, the middle beam 3 can be uniformly transmitted to the vehicle chassis through the first sleeve 6, the second sleeve 7, the reinforcing member 8, and the first fastening bolt and the second fastening bolt, solving the problem of deformation or damage of the middle beam 3 or the connecting part of the middle beam 3 and the vehicle chassis caused by load concentration in the prior art.

[0075] In some embodiments, the first sleeve 6 and the second sleeve 7 each comprise two parts, one part being the first sleeve part 10 and the other part being the second sleeve part 11. The first sleeve part 10 has an internal thread, and the inner diameter of the second sleeve part 11 is greater than that of the first sleeve part 10. The shank of the first fastening bolt is matched with the internal thread of the first sleeve part 10 of the first sleeve 6, and the shank of the second fastening bolt is matched with the internal thread of the first sleeve part 10 of the second sleeve 7. The head of the first fastening bolt is located in the second sleeve part 11 of the first sleeve 6, and the head of the second fastening bolt is located in the second sleeve part 11 of the second sleeve 7.

[0076] The first barrel part 10 of the first sleeve 6 is in threaded fit with the first fastening bolt, so that the intermediate beam 3 can transfer the acting force received by the intermediate beam 3 to the first fastening bolt through the first sleeve 6, and then transfer it to the vehicle chassis better through the first fastening bolt. Similarly, the intermediate beam 3 can also transfer the acting force received by the intermediate beam 3 to the second fastening bolt better through the second sleeve 7, and then transfer it to the vehicle chassis through the second fastening bolt.

[0077] Exemplarily, the cross-section of the intermediate beam 3 can be, but is not limited to, a "mouth" shape or a "C" shape. Here, the "C" shape can mean that the opening of the cross-section of the intermediate beam 3 faces any one of the two commutation batteries. The intermediate beam 3 with the above cross-sectional form of the intermediate beam 3 has a hollow structure. When the cross-section of the intermediate beam 3 is in the "mouth" shape, the hollow structure can be understood as a hollow cavity 301; when the cross-section of the intermediate beam 3 is in the "C" shape, the hollow structure can be understood as a hollow cavity 301 with a side opening. The bottoms of the second barrel parts 11 of the first sleeve 6 and the second sleeve 7 are respectively flush with the bottom surface of the intermediate beam 3. For example, the bottoms of the second barrel parts 11 can be welded to the bottom surface of the intermediate beam 3 respectively. Alternatively, the bottoms of the second barrel parts 11 of the first sleeve 6 and the second sleeve 7 are located inside the hollow cavity 301 of the intermediate beam 3 to prevent the second barrel parts 11 from being exposed outside, and the bottoms of the second barrel parts 11 of the first sleeve 6 and the second sleeve 7 are welded to the inner bottom surface of the hollow cavity 301 of the intermediate beam 3. Of course, the first fastening bolt and the second fastening bolt can respectively extend into the first sleeve 6 and the second sleeve 7 through the bottoms of the second barrel parts 11 of the first sleeve 6 and the second barrel parts 11 of the second sleeve 7.

[0078] The outer diameter of the second barrel part 11 can also be larger than the outer diameter of the first barrel part 10. A step surface is formed between the second barrel part 11 and the first barrel part 10, and this step surface can abut against the inner top surface of the hollow cavity 301 of the intermediate beam 3. A reinforcing member can be arranged between the second barrel part 11 of the first sleeve 6 and the second barrel part 11 of the second sleeve 7. Of course, the above step surface can also abut against the bottom surface of the reinforcing member, that is, the two ends of the reinforcing member can be respectively sleeved on the first barrel part 10 of the first sleeve 6 and the first barrel part 10 of the second sleeve 7, or the two ends of the reinforcing member can be respectively welded to the first barrel part 10 of the first sleeve 6 and the first barrel part 10 of the second sleeve 7.

[0079] The first barrel part 10 can extend upward from the inside of the hollow cavity 301 of the intermediate beam 3 to the outside of the intermediate beam 3. The extension distance can be set according to the length of the fastening bolt and the depth of the threaded hole of the vehicle chassis, and the specific extension distance is not specifically limited.

[0081] In some embodiments, the first sleeve 6 and the second sleeve 7 have the same structure, and the first fastening bolt and the second fastening bolt have the same structure, so that the intermediate beam 3 can transmit the force it receives to the vehicle chassis more evenly.

[0082] Here, it can be understood that, for the sake of clarity in describing this application, the sleeve is described as a first sleeve 6 and a second sleeve 7, and the first sleeve 6 and the second sleeve 7 are the same sleeve. Similarly, the fastening bolt is described as a first fastening bolt and a second fastening bolt, and the first fastening bolt and the second fastening bolt can also be the same fastening bolt.

[0083] In some embodiments, the intermediate beam 3 is provided with a first mounting hole and a second mounting hole. The outer peripheral surface of the first sleeve 6 abuts against the inner wall surface of the first mounting hole, and the outer peripheral surface of the second sleeve 7 abuts against the inner wall surface of the second mounting hole. Continuing with the embodiment described above where the cross-section of the intermediate beam 3 is "U"-shaped and the intermediate beam 3 has a hollow cavity 301, the first mounting hole and the second mounting hole respectively penetrate the upper and lower surfaces of the intermediate beam 3. Figure 3 The outer peripheral surface of the first cylindrical portion 10 of the first sleeve 6 can abut against the inner wall surface of the first mounting hole, and the outer peripheral surface of the first cylindrical portion 10 of the second sleeve 7 can abut against the inner wall surface of the second mounting hole. For example, the outer peripheral surface of the first cylindrical portion 10 of the first sleeve 6 can be welded to the inner wall surface of the first mounting hole, and the outer peripheral surface of the first cylindrical portion 10 of the second sleeve 7 can be welded to the inner wall surface of the second mounting hole, so that the first sleeve 6 and the second sleeve 7 can form a firm connection with the intermediate beam 3, thereby enabling the intermediate beam 3 to better transmit the force it receives to the first sleeve 6 and the second sleeve 7.

[0084] In some embodiments, the top ends of the first sleeve 6 and the second sleeve 7 extend outward from the upper surface of the intermediate beam 3 and are connected to the vehicle chassis. As one feasible embodiment, a first annular hole and a second annular hole adapted to the first cylindrical portion 10 can also be provided on the vehicle chassis. The first annular hole and the second annular hole are located on the outer periphery of the first threaded hole and the second threaded hole on the vehicle chassis, respectively. The first annular hole and the first threaded hole are coaxially arranged. The first cylindrical portion 10 of the first sleeve 6 extends into the first annular hole, and the first cylindrical portion 10 of the second sleeve 7 extends into the second annular hole. The intermediate beam 3 can transmit the force received by the intermediate beam 3 to the vehicle chassis through the first sleeve 6 and the second sleeve 7.

[0085] This application also provides a vehicle, including a vehicle chassis and a battery swapping frame as described in any of the above embodiments, which is fastened to the vehicle chassis.
