Description

Technical Field

[0001] The present application relates to the field of vehicle battery swapping, and more particularly to a vehicle battery assembly device and method. Background Art

[0002] In some related technologies, during the process of swapping the battery of a vehicle and assembling the battery to the vehicle, there are problems such as low battery swapping efficiency. Summary of the Invention

[0003] Some embodiments of the present application provide a vehicle battery assembly device and method for alleviating the problem of low battery swapping efficiency.

[0004] Some embodiments of the present application provide a vehicle battery assembly device, including a first assembly component, which includes: two first beams, both extending along a first direction, and the two first beams are configured to be respectively arranged corresponding to two vehicle main beams one by one; and at least two second beams, both extending along a second direction, and respectively connecting the two first beams, and the setting positions of the at least two second beams between the two first beams are respectively in one-to-one correspondence with the setting positions of at least two battery mounting beams between the two vehicle main beams, and the at least two second beams are configured to be respectively connected to the at least two battery mounting beams one by one to position the at least two battery mounting beams between the two vehicle main beams; the first direction intersects with the second direction.

[0005] In the above embodiment, the setting positions of the at least two second beams between the two first beams are respectively in one-to-one correspondence with the setting positions of the at least two battery mounting beams between the two vehicle main beams, and a battery mounting beam is arranged on each second beam. When the two first beams are respectively arranged corresponding to the two vehicle main beams one by one, the at least two battery mounting beams arranged on the at least two second beams can be positioned between the two vehicle main beams to realize the positioning of each battery mounting beam, and then the battery mounting beam and the vehicle main beam are connected through a connecting piece, that is, the connection between the battery mounting beam and the vehicle main beam can be realized. Through the first assembly component, the positioning and installation of multiple battery mounting beams can be realized, with accurate positioning, simple and convenient operation, and alleviating the problems such as difficult positioning of the battery mounting beam and low battery swapping efficiency during the vehicle battery swapping process.

[0006] In some embodiments, the first assembly component further includes an adjusting component, and the adjusting component is arranged at the connection between the second beam and the first beam, and the adjusting component is configured to adjust the gap between the second beam and the first beam.

[0007] Since the vehicle frame is generally prefabricated in advance, in the process of assembling the multiple battery mounting beams in the middle of the battery to the two vehicle frames through the first assembly component, due to the unevenness of the lower wing surface of the vehicle frame, the floating adjustment component that comes with the first assembly component can ensure that the assembly process is not affected by the flatness of the frame.

[0008] In some embodiments, the adjustment assembly includes an elastic member, and the second beam and the first beam are configured to overcome the elastic force of the elastic member under the action of an external force and move closer to each other, or at least move away from each other under the action of the elastic force of the elastic member.

[0009] In the above embodiment, the elastic member can automatically adjust its height within a certain range to adapt to the slight undulations and unevenness of the vehicle beam surface, ensuring that each second beam always maintains good contact with the vehicle beam, so that each battery mounting beam connected to each second beam is basically at the same height, alleviating the problem of inconsistent heights of each battery mounting beam caused by the uneven surface of the vehicle beam.

[0010] In some embodiments, the adjustment assembly includes: a first seat body, fixedly disposed on a side of the first beam away from the second beam; a second seat body, movably disposed on a side of the second beam away from the first beam; a first connecting member, connecting the second seat body, the second beam, the first beam and the first seat body; and an elastic member, disposed on the first connecting member and located between the first seat body and the second seat body.

[0011] In the above embodiment, the first seat body is fixedly arranged on the side of the first beam away from the second beam, and the relative position of the first seat body and the first beam remains unchanged. The second seat body is movably arranged on the side of the second beam away from the first beam, and there is a moving space between the second seat body and the second beam. When the second beam contacts the raised portion on the surface of the vehicle beam, the raised portion pushes the second beam, and the first beam drives the first seat body to move toward the second seat body due to the gravity, so that the gap between the part of the second beam corresponding to the raised portion and the first beam is reduced, and the elastic member is compressed and shortened in length, so that the second beam can be closely attached to the raised portion of the vehicle beam. When the second beam contacts the concave portion on the surface of the vehicle beam, the second beam covers the concave portion, and the force of the elastic member enables the second beam to be pressed against the concave portion to maintain the contact between the second beam and the vehicle beam. By setting the elastic member, the second beam can always maintain good contact with the vehicle beam at different height positions on the surface of the vehicle beam, and adapt to the slight undulations and unevenness of the surface of the vehicle beam.

[0012] In some embodiments, the second seat is configured to fit over the vehicle frame.

[0013] In the above embodiments, the adjusting assembly is provided at the connection between the second beam and the first beam. Since there are multiple second beams, a plurality of adjusting assemblies are sequentially provided along the length extension direction of the first beam. Each second beam abuts against the vehicle frame through a second seat body. Through the floating adjustment of the elastic member, the plurality of second seat bodies can form good contact with the surface of the vehicle frame at multiple contact points to disperse the acting force.

[0014] In some embodiments, a long slot extending in the third direction is provided on the first connecting member, and the adjusting assembly further includes a limiting member. The limiting member is provided on the first seat body and extends into the long slot.

[0015] In the above embodiments, the first connecting member sequentially connects the second seat body, the second beam, the first beam, and the first seat body in the third direction. The limiting member is provided on the first seat body and has a fixed relative position with the first seat body. The limiting member extends into the long slot provided on the first connecting member, and the length extension direction of the long slot is the same as the third direction. Therefore, the first connecting member can be limited by the limiting member to prevent the first connecting member from detaching from the first seat body in the third direction.

[0016] In some embodiments, the first assembly component further includes a second connecting member and a first positioning member. The second connecting member and the first positioning member are disposed adjacent to each other on the second beam. The first positioning member is configured to cooperate with a first positioning hole on the battery mounting beam for positioning, and the second connecting member is configured to connect with the battery mounting beam.

[0017] In the above embodiments, the first positioning member cooperates with the first positioning hole on the battery mounting beam for positioning, which can realize the positioning of the battery mounting beam and the second beam, reducing the position deviation of the battery mounting beam; after the battery mounting beam is positioned, by connecting the second beam and the battery mounting beam through the second connecting member adjacent to the first positioning member, the rework caused by the position deviation of the battery mounting beam can be reduced, improving the work efficiency and reducing the rework rate.

[0018] In some embodiments, the first assembly component further includes: a first lifting plate; and at least two first connecting plates, each first connecting plate connecting the first beam and the first lifting plate.

[0020] In some embodiments, the vehicle battery assembly device further includes a second assembly component, and the second assembly component includes at least two third beams. Each third beam has a mounting portion for connecting a battery bracket, and the at least two third beams are configured to be respectively arranged in one-to-one correspondence with the at least two battery mounting beams, so as to position the battery bracket connected to the mounting portion on a side of the vehicle frame away from the battery mounting beam, for preparing for the connection between the battery bracket and the vehicle frame.

[0021] In the above embodiments, each third beam has a mounting portion for connecting a battery bracket. After the at least two third beams are respectively arranged in one-to-one correspondence with the at least two battery mounting beams, the mounting portion is located on a side of the vehicle frame away from the battery mounting beam. Therefore, after the battery bracket is mounted on the mounting portion, the battery bracket can be correspondingly positioned on a side of the vehicle frame away from the battery mounting beam, that is, the battery bracket is located at the mounting position for mounting with the vehicle frame. Then, the battery bracket and the vehicle frame can be connected through a connecting member. By the method of positioning and assisting the installation of the battery bracket through the second assembly component, the problem of position deviation of the battery bracket can be reduced, and the installation efficiency of the battery bracket can be improved.

[0022] In some embodiments, a second positioning member is provided on the third beam, and the second positioning member is configured to cooperate with a second positioning hole on the battery mounting beam for positioning, so as to position the mounting portion on a side of the vehicle frame away from the battery mounting beam.

[0023] In the above embodiments, a second positioning member for cooperating with the second positioning hole on the battery mounting beam is provided on the third beam. After the second positioning member and the second positioning hole are cooperatively positioned, the mounting portion can be located on a side of the vehicle frame away from the battery mounting beam, that is, the mounting portion is located at the mounting position for mounting the battery bracket and the vehicle frame. At this time, when the battery bracket is mounted on the mounting portion, the battery bracket can be smoothly positioned at the mounting position for mounting with the vehicle frame. Then, the battery bracket and the vehicle frame can be connected through a connecting member, reducing the problem of position deviation of the battery bracket and improving the installation efficiency of the battery bracket.

[0024] In some embodiments, an assembly hole is provided on the third beam, and the assembly hole is configured to allow an adjusting member to pass through, so that the adjusting member is located in a gap between the vehicle frame and the battery bracket.

[0025] In the above embodiments, after the adjusting member passes through the assembly hole on the third beam, it can be located in a gap between the vehicle frame and the battery bracket, for adjusting the cumulative machining error of components such as the vehicle frame and the battery bracket in the second direction, and improving the connection quality between the battery bracket and the vehicle frame.

[0026] In some embodiments, a third positioning member is provided on the mounting portion, and the third positioning member is configured to cooperate with a third positioning hole on the battery bracket for positioning.

[0027] In the above embodiments, the cooperation between the third positioning member and the third positioning hole can achieve the positioning of the battery bracket, so that the battery bracket is located at an accurate position for connecting with the vehicle frame, reducing the position deviation of the battery bracket.

[0028] In some embodiments, the second assembly component further includes: at least two fourth beams, each fourth beam being connected to the at least two third beams; a second lifting plate; and at least two second connecting plates, each second connecting plate connecting the fourth beam and the second lifting plate.

[0029] In the above embodiments, the second connecting plate connects the fourth beam and the second lifting plate. The second assembly component can be lifted by the second lifting plate, moved to the position between the two vehicle frames to assist in installing the battery bracket, and after the battery bracket is installed, the second assembly component can be removed by the second lifting plate.

[0030] Some embodiments of the present application further provide a vehicle battery assembly method, which uses the vehicle battery assembly device in the above embodiments. The method includes the following steps: respectively connecting at least two second beams in the first assembly component with at least two battery mounting beams in a one-to-one correspondence; lifting the first assembly component to the position where the two vehicle frames are located, and making the two first beams respectively arranged corresponding to the two vehicle frames, so that at least two battery mounting beams are located between the two vehicle frames; connecting each battery mounting beam with the two vehicle frames; disassembling the connection between at least two second beams and at least two battery mounting beams, and removing the first assembly component.

[0031] In the above embodiments, in the first assembly component, the arrangement positions of at least two second beams between the two first beams respectively correspond to the arrangement positions of at least two battery mounting beams between the two vehicle frames, and a battery mounting beam is arranged on each second beam; in the case of respectively arranging the two first beams corresponding to the two vehicle frames, at least two battery mounting beams arranged on at least two second beams can be positioned between the two vehicle frames to achieve the positioning of the battery mounting beams, and then the battery mounting beams are connected to the vehicle frames through connecting members, that is, the connection between the battery mounting beams and the vehicle frames can be realized. Through the first assembly component, the positioning and installation of multiple battery mounting beams can be realized, with accurate positioning, simple and convenient operation, alleviating the problems of difficult positioning of battery mounting beams and low battery swapping efficiency during the vehicle battery swapping process.

[0032] In some embodiments, the vehicle battery assembly device further includes a second assembly component, and the second assembly component includes at least two third beams; each third beam has a mounting portion for connecting a battery bracket, and the at least two third beams are configured to be respectively arranged in one-to-one correspondence with the at least two battery mounting beams, so as to position the battery bracket connected to the mounting portion on the side of the vehicle frame away from the battery mounting beam, in preparation for connecting the battery bracket to the vehicle frame; the vehicle battery assembly method further includes the following steps: hoisting the second assembly component to the position where two vehicle frames are located, and making the at least two third beams respectively arranged in one-to-one correspondence with the at least two battery mounting beams, positioning the mounting portion of the third beam on the side of the vehicle frame away from the battery mounting beam; connecting a battery bracket to the mounting portion; connecting the battery bracket to the vehicle frame; disassembling the connection between the third beam and the battery bracket, and removing the second assembly component.

[0033] In the above embodiment, each third beam has a mounting portion for connecting a battery bracket. After the at least two third beams are respectively attached to the at least two battery mounting beams in one-to-one correspondence, the mounting portion is located on the side of the vehicle frame away from the battery mounting beam. Therefore, after installing the battery bracket on the mounting portion, the battery bracket can be correspondingly positioned on the side of the vehicle frame away from the battery mounting beam, that is, the battery bracket is located at the installation position for installing with the vehicle frame. Then, the battery bracket and the vehicle frame can be connected through a connecting member. By using the second assembly component to assist in positioning and installing the battery bracket, the problem of position deviation of the battery bracket can be reduced, and the installation efficiency of the battery bracket can be improved.

[0034] In some embodiments, the third beam is provided with an assembly hole. In the step of connecting the battery bracket to the vehicle frame, an adjustment member is first inserted into the gap between the battery bracket and the vehicle frame through the assembly hole, and then the battery bracket, the adjustment member, and the vehicle frame are connected.

[0035] In the above embodiment, after passing through the assembly hole on the third beam, the adjustment member is located in the gap between the vehicle frame and the battery bracket, and can adjust the cumulative machining error of components such as the vehicle frame and the battery bracket in the second direction. Then, connecting the battery bracket to the vehicle frame can improve the connection quality between the battery bracket and the vehicle frame.

[0036] Based on the above technical solutions, the present application has at least the following beneficial effects:

When the two first beams are respectively arranged corresponding to the two vehicle main beams one-to-one, the at least two battery mounting beams arranged on the at least two second beams can be positioned between the two vehicle main beams to realize the positioning of each battery mounting beam, and then the battery mounting beam and the vehicle main beam are connected through a connecting piece, thus realizing the connection between the battery mounting beam and the vehicle main beam. Through the first assembly component, the positioning and installation of multiple battery mounting beams can be realized, with accurate positioning and simple and convenient operation, alleviating the problems of difficult positioning of the battery mounting beam and low battery swapping efficiency during the vehicle battery swapping process.

Vehicle 200 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is disposed inside vehicle 200. The battery 100 can be disposed at the bottom, the head or the tail of vehicle 200. The battery 100 can be used for power supply of vehicle 200. For example, the battery 100 can be used as the operating power source of vehicle 200. Vehicle 200 can also include an axle 201, wheels 202 connected to the axle 201, as well as a motor 203 and a controller 204.

The battery 100 can be used to provide electrical energy for the operation of the motor 203 and other components in the vehicle.

[0071] In some embodiments of the present application, the battery 100 can not only be used as the operating power source of vehicle 200, but also be used as the driving power source of vehicle 200, replacing or partially replacing fuel or natural gas to provide driving power for vehicle 200.

[0072] Reference Figure 2 , Figure 2 Exploded structural diagram of battery 100 provided by some embodiments of the present application. The battery 100 includes a box body 101 and battery cells 102. The battery cells 102 are accommodated in the box body 101. The box body 101 includes a first box body 101a and a second box body 101b. The first box body 101a and the second box body 101b cover each other. The first box body 101a and the second box body 101b jointly define an accommodation space for accommodating the battery cells 102. The second box body 101b can be a hollow structure with one end open. The first box body 101a can be a plate-like structure. The first box body 101a covers the open side of the second box body 101b so that the first box body 101a and the second box body 101b jointly define an accommodation space. The first box body 101a and the second box body 101b can also both be hollow structures with one side open, and the open side of the first box body 101a covers the open side of the second box body 101b. Of course, the box body 101 formed by the first box body 101a and the second box body 101b can be in various shapes, such as a cylinder or a cuboid, etc.

[0073] There can be multiple battery cells 102. The multiple battery cells 102 can be connected in series, in parallel or in a mixed connection. A mixed connection means that there are both series and parallel connections among the multiple battery cells 102. The multiple battery cells 102 can be connected in series, in parallel or in a mixed connection together, and then the whole formed by the multiple battery cells 102 is accommodated in the box body 101. Of course, the battery 100 can also be in the form of multiple battery cells 102 first connected in series, in parallel or in a mixed connection to form battery modules, and then the multiple battery modules are connected in series, in parallel or in a mixed connection to form a whole and are accommodated in the box body 101.

[0074] The battery cell 102 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 102 can be in a cylindrical shape, a flat shape, a cuboid shape, or other shapes, etc.

[0075] Reference Figure 3a and Figure 3b Moreover, the vehicle 200 further includes a frame or a chassis, and the frame or the chassis includes two vehicle girders 205, and the vehicle girders 205 provide a foundation for installing and supporting key components such as the vehicle body, the motor, the transmission, the battery, or the fuel tank. The two vehicle girders 205 are arranged at intervals along the first direction Y, and the length extension direction of each vehicle girder 205 is consistent with the first direction X. Among them, the first direction X intersects with the second direction Y, the first direction X intersects with the third direction Z, and the second direction Y intersects with the third direction Z. Optionally, the first direction X is perpendicular to the second direction Y, the first direction X is perpendicular to the third direction Z, and the second direction Y is perpendicular to the third direction Z.

[0076] Reference Figure 4 Moreover, in some embodiments, the battery 100 is installed on the vehicle girder 205 through components such as the battery mounting beam 206 and the battery bracket 207. The battery mounting beam 206 is used for mounting the battery 100, and generally at least two battery mounting beams 206 are provided. Optionally, the number of the battery mounting beams 206 is four. At least two battery mounting beams 206 are located between the two vehicle girders 205, and the battery mounting beams 206 are arranged at intervals along the first direction X, and the length extension direction of each battery mounting beam 206 is consistent with the second direction Y, and both ends of each battery mounting beam 206 are respectively connected to a vehicle girder 205. The battery brackets 207 are arranged on the sides of the two vehicle girders 205 away from each other, and components such as the battery swapping box 209 can be supported through the battery brackets 207.

[0077] In some related technologies, during the process of swapping the battery of the vehicle and installing the battery 100 onto the vehicle, there are problems such as difficult positioning of components such as the battery mounting beam 206 or the battery bracket 207, which greatly reduces the battery swapping efficiency and the battery swapping success rate. Moreover, if the position accuracy of the guiding positioning holes and the locking and mounting holes of the battery bracket 207 cannot be guaranteed, it will also affect the positioning and fixing of the battery swapping box 209 when the vehicle enters the battery swapping station for battery swapping later, greatly reducing the battery swapping success rate.

[0078] Based on this, some embodiments of the present disclosure provide a vehicle battery assembly device and method for alleviating the problems of difficult positioning of components such as the battery mounting beam 206 or the battery bracket 207 and low battery swapping efficiency during the vehicle battery swapping process.

[0079] Reference Figure 5, in some embodiments, the vehicle battery assembly device includes a first assembly component 1, and the first assembly component 1 includes two first beams 11 and at least two second beams 12.

[0081] At least two second beams 12 all extend along the second direction Y, and are respectively connected to the two first beams 11. The arrangement positions of the at least two second beams 12 between the two first beams 11 are respectively in one-to-one correspondence with the arrangement positions of at least two battery mounting beams 206 between the two vehicle main beams 205. The at least two second beams 12 are configured to be respectively connected to the at least two battery mounting beams 206 in one-to-one correspondence to position the at least two battery mounting beams 206 between the two vehicle main beams 205; the first direction X intersects with the second direction Y.

[0082] In the above embodiments, the two first beams 11 are arranged at intervals along the second direction Y, and the length extension direction of each first beam 11 is consistent with the first direction X. Each of the second beams 12 is arranged at intervals along the first direction X, and the length extension direction of each second beam 12 is consistent with the second direction Y. Each of the second beams 12 is arranged between the two first beams 11, and both ends of each second beam 12 are respectively connected to the two first beams 11 in one-to-one correspondence.

[0083] In the above embodiments, the arrangement positions of the at least two second beams 12 between the two first beams 11 are respectively in one-to-one correspondence with the arrangement positions of at least two battery mounting beams 206 between the two vehicle main beams 205, and a battery mounting beam 206 is arranged on each second beam 12. When the two first beams 11 are respectively arranged in one-to-one correspondence with the two vehicle main beams 205, the at least two battery mounting beams 206 arranged on the at least two second beams 12 can be positioned between the two vehicle main beams 205 to realize the positioning of each battery mounting beam 206, and then the battery mounting beam 206 and the vehicle main beam 205 are connected through a connecting piece, that is, the connection between the battery mounting beam 206 and the vehicle main beam 205 can be realized. Through the first assembly component 1, the positioning and installation of multiple battery mounting beams 206 can be realized, with accurate positioning, simple and convenient operation, and alleviating the problems of difficult positioning of the battery mounting beam 206 and low battery swapping efficiency during the vehicle battery swapping process.

[0084] Reference Figure 6 , in some embodiments, the first assembly component 1 further includes an adjusting component 13, and the adjusting component 13 is arranged at the connection between the second beam 12 and the first beam 11. The adjusting component 13 is configured to adjust the gap between the second beam 12 and the first beam 11.

[0085] Reference Figure 6 and Figure 7Since the vehicle beam 205 is generally prefabricated in advance, in the process of assembling the multiple battery mounting beams 206 in the middle of the battery 100 to the two vehicle beams 205 through the first assembly component 1, due to the unevenness of the lower wing surface 205a of the vehicle beam 205, the floating adjustment component 13 provided by the first assembly component 1 can ensure that the flatness of the beam is not affected during the assembly process.

[0086] In some embodiments, the adjustment assembly 13 includes an elastic member 133 , and the second beam 12 and the first beam 11 are configured to overcome the elastic force of the elastic member 133 under the action of an external force and move closer to each other, or at least move away from each other under the action of the elastic force of the elastic member 133 .

[0087] In the above embodiment, the two first beams 11 are respectively arranged in one-to-one correspondence with the two vehicle beams 205, and the second beam 12 is close to the vehicle beam 205 relative to the first beam 11, and the second beam 12 is adjacent to the vehicle beam 205. In the case that the vehicle beam 205 has an uneven surface, when the second beam 12 contacts the raised portion on the surface of the vehicle beam 205, the raised portion pushes the second beam 12, and the second beam 12 compresses the elastic member 133, so that the gap between the part of the second beam 12 corresponding to the raised portion and the first beam 11 is reduced, and the elastic member 133 is compressed and shortened, so that the second beam 12 can be close to the raised portion of the vehicle beam 205. When the second beam 12 contacts the recessed portion on the surface of the vehicle beam 205, the elastic member 133 will extend, so that the second beam 12 can cover the recessed portion and maintain contact. By setting the elastic member 133, the second beam 12 can always maintain good contact with the vehicle beam 205 at different height positions on the surface of the vehicle beam 205, and adapt to the slight undulations and unevenness of the surface of the vehicle beam 205. Therefore, the elastic member 133 can automatically adjust the height within a certain range to adapt to the slight undulations and unevenness of the surface of the vehicle beam 205, ensure that each second beam 12 always maintains good contact with the vehicle beam 205, and make each battery mounting beam 206 connected to each second beam 12 basically at the same height, alleviating the problem of inconsistent heights of each battery mounting beam 206 caused by the uneven surface of the vehicle beam 205.

[0088] refer to Figure 8 and Figure 9 In some embodiments, the adjustment assembly 13 includes a first seat body 131 , a second seat body 132 , a first connecting member 134 and an elastic member 133 .

[0089] The first base 131 is fixedly disposed on a side of the first beam 11 away from the second beam 12 .

[0090] The second base 132 is movably disposed on a side of the second beam 12 away from the first beam 11 .

[0091] The first connecting member 134 connects the second base body 132, the second beam 12, the first beam 11 and the first base body 131.

[0092] The elastic member 133 is provided on the first connecting member 134 and is located between the first base body 131 and the second base body 132.

[0093] In the above embodiment, the first base body 131 is fixedly provided on the side of the first beam 11 away from the second beam 12, and the relative position between the first base body 131 and the first beam 11 remains unchanged. The second base body 132 is movably provided on the side of the second beam 12 away from the first beam 11, and there is a space for movement between the second base body 132 and the second beam 12. The battery mounting beam 206 is mounted on the second beam 12. The gravitational force of the battery mounting beam 206 causes the second beam 12 to be close to the vehicle frame 205. When the vehicle frame 205 has an uneven surface, when the second beam 12 contacts the convex portion on the surface of the vehicle frame 205, the convex portion pushes the second beam 12, and the first beam 11 drives the first base body 131 to move towards the second base body 132 due to the gravitational force, reducing the gap between the corresponding portion of the second beam 12 and the first beam 11. The elastic member 133 will be compressed and shorten in length, enabling the second beam 12 to closely adhere to the convex portion of the vehicle frame 205. When the second beam 12 contacts the concave portion on the surface of the vehicle frame 205, the second beam 12 covers the concave portion, and the acting force of the elastic member 133 enables the second beam 12 to press towards the concave portion, maintaining the contact between the second beam 12 and the vehicle frame 205. By providing the elastic member 133, the second beam 12 can always maintain good contact with the vehicle frame 205 at different height positions on the surface of the vehicle frame 205, adapting to the minute undulations and unevenness of the surface of the vehicle frame 205.

[0094] Reference Figure 9 Referring to, in some embodiments, the adjusting assembly 13 further includes a third connecting member 137 for connecting the first base body 131 and the first beam 11. Optionally, the third connecting member 137 includes a bolt.

[0095] In some embodiments, the first connecting member 134 and the second base body 132 are integrally formed.

[0096] In some embodiments, the second base body 132 is configured to fit the vehicle frame 205.

[0097] In the above embodiments, the adjusting assembly 13 is provided at the connection between the second beam 12 and the first beam 11. Since there are multiple second beams 12, a plurality of adjusting assemblies 13 are sequentially provided along the length extension direction of the first beam 11. Each second beam 12 abuts against the vehicle frame 205 through a second seat body 132. Through the floating adjustment of the elastic member 133, the plurality of second seat bodies 132 can form good contact with the surface of the vehicle frame 205 at multiple contact points, dispersing the acting force.

[0098] In some embodiments, the elastic member 133 includes elastic components such as springs.

[0099] In some embodiments, a long slot 135 extending in the third direction Z is provided on the first connecting member 134. The adjusting assembly 13 further includes a limiting member 136. The limiting member 136 is provided on the first seat body 131 and extends into the long slot 135.

[0100] In the above embodiments, the first connecting member 134 sequentially connects the second seat body 132, the second beam 12, the first beam 11, and the first seat body 131 along the third direction Z. The limiting member 136 is provided on the first seat body 131 and its relative position with the first seat body 131 remains unchanged. The limiting member 136 extends into the long slot 135 provided on the first connecting member 134. The length extension direction of the long slot 135 is consistent with the third direction Z. Therefore, the first connecting member 134 can be limited by the limiting member 136 to prevent the first connecting member 134 from detaching from the first seat body 131 in the third direction Z.

[0101] Reference Figure 10 Referring to, in some embodiments, the first assembly component 1 further includes a second connecting member 16 and a first positioning member 17.

The first positioning member 17 is configured to cooperate with a first positioning hole on the battery mounting beam 206 for positioning, and the second connecting member 16 is configured to connect with the battery mounting beam 206.

[0102] In the above embodiments, the first positioning member 17 cooperates with the first positioning hole on the battery mounting beam 206 for positioning, which can realize the positioning of the battery mounting beam 206 and the second beam 12, reducing the position deviation of the battery mounting beam 206; after the battery mounting beam 206 is positioned, connecting the second beam 12 and the battery mounting beam 206 through the second connecting member 16 adjacent to the first positioning member 17 can reduce the rework caused by the position deviation of the battery mounting beam 206, improve the work efficiency, and reduce the rework rate.

Through the first lifting plate 14, the first assembly component 1 can be lifted, and the first assembly component 1 can be moved to the position of two vehicle main beams 205 to assist in installing the battery mounting beam 206. After the installation of the battery mounting beam 206 is completed, the first assembly component 1 can be removed through the first lifting plate 14.

[0106] In some embodiments, the first assembly component 1 includes four first connecting plates 15, and all four first connecting plates 15 are connected to the first lifting plate 14. One of the two first connecting plates among the four first connecting plates 15 is connected to one of the two first beams 11, and the other two first connecting plates among the four first connecting plates 15 are connected to the other of the two first beams 11.

[0107] In some embodiments, the first lifting plate 14 is located in the middle of the first assembly component 1.

[0108] Reference Figure 11 , the connection between the battery mounting beam 206 and the vehicle main beam 205 is completed through the first assembly component 1. Since a battery bracket 207 also needs to be provided on the side where the two vehicle main beams 205 are far away from each other, therefore, the present disclosure embodiment also provides a second assembly component 2, and the second assembly component 2 is used for positioning and assembling the battery bracket 207.

[0109] Reference Figure 12 , in some embodiments, the vehicle battery assembly device further includes a second assembly component 2. The second assembly component 2 includes at least two third beams 21. Each third beam 21 has a mounting portion 211 for connecting the battery bracket 207. The at least two third beams 21 are configured to be respectively arranged in one-to-one correspondence with at least two battery mounting beams 206, so as to position the battery bracket 207 connected to the mounting portion 211 on the side of the vehicle main beam 205 away from the battery mounting beam 206, for preparing for the connection between the battery bracket 207 and the vehicle main beam 205.

[0110] In the above embodiment, the respective third beams 21 are arranged at intervals along the first direction X, and the length extension direction of each third beam 21 is the same as the second direction Y.

[0111] In the above embodiments, each third beam 21 has a mounting portion 211 for connecting the battery bracket 207. After at least two third beams 21 are respectively arranged in one-to-one correspondence with at least two battery mounting beams 206, the mounting portion 211 is located on the side of the vehicle frame 205 away from the battery mounting beam 206. Therefore, after the battery bracket 207 is mounted on the mounting portion 211, the battery bracket 207 can be correspondingly positioned on the side of the vehicle frame 205 away from the battery mounting beam 206, that is, the battery bracket 207 is located at the mounting position for mounting with the vehicle frame 205. Then, the battery bracket 207 and the vehicle frame 205 can be connected by a connecting member. By the method of positioning and assisting the installation of the battery bracket 207 through the second assembly component 2, the problem of position deviation of the battery bracket 207 can be reduced, and the installation efficiency of the battery bracket 207 can be improved.

The reinforcing member 27a can also connect the two fourth beams 22 located in the middle to increase the structural strength of the second assembly component 2.

[0116] Reference Figure 13 and Figure 14 In some embodiments, a second positioning member 23 is provided on the third beam 21. The second positioning member 23 is configured to cooperate with a second positioning hole on the battery mounting beam 206 for positioning, so as to position the mounting portion 211 on the side of the vehicle frame 205 away from the battery mounting beam 206.

[0117] In the above embodiments, a second positioning member 23 is provided on the third beam 21 and is configured to cooperate with the second positioning holes on the battery mounting beam 206 for positioning. After the second positioning member 23 cooperates with the second positioning holes for positioning, the mounting portion 211 can be located on the side of the vehicle frame 205 away from the battery mounting beam 206, that is, the mounting portion 211 is located at the mounting position where the battery bracket 207 is mounted to the vehicle frame 205. At this time, when the battery bracket 207 is mounted on the mounting portion 211, the battery bracket 207 can be successfully positioned at the mounting position for mounting to the vehicle frame 205. Then, the battery bracket 207 and the vehicle frame 205 can be connected by a connecting member, reducing the problem of position deviation of the battery bracket 207 and improving the mounting efficiency of the battery bracket 207.

The fourth connecting member 28 is disposed adjacent to the second positioning member 23 and is configured to connect the third beam 21 and the battery mounting beam 206 to fix the position of the second assembly component 2.

[0119] In the above embodiments, after the second positioning member 23 on the third beam 21 cooperates with the second positioning holes on the battery mounting beam 206 for positioning, the position of the second assembly component 2 is accurate. Then, by connecting the third beam 21 and the battery mounting beam 206 through the fourth connecting member 28 adjacent to the second positioning member 23, the position deviation of the second assembly component 2 can be reduced and the position of the second assembly component 2 can be fixed.

[0120] Reference Figures 15 to 18 , in some embodiments, an assembly hole 24 is provided on the third beam 21 and is configured to allow the adjusting member 208 to pass through so that the adjusting member 208 is located in the gap between the vehicle frame 205 and the battery bracket 207.

[0121] In the above embodiments, after the adjusting member 208 passes through the assembly hole 24 on the third beam 21, it can be located in the gap between the vehicle frame 205 and the battery bracket 207 to be used for adjusting the cumulative machining error of components such as the vehicle frame 205 and the battery bracket 207 in the second direction Y and improving the connection quality between the battery bracket 207 and the vehicle frame 205.

[0124] In the above embodiments, the third positioning member 25 can be engaged with the third positioning hole to position the battery bracket 207, so that the battery bracket 207 is located at an accurate position for connecting with the vehicle frame 205, reducing the position deviation of the battery bracket 207.

[0125] Reference Figure 19 and Figure 20 , the third positioning member 25 is inserted through the mounting portion 211. A buckle 251 is provided on the third positioning member 25, and a slot 212 is provided on the mounting portion 211. In a state where the third positioning member 25 is not inserted into the third positioning hole on the battery bracket 207, the buckle 251 is engaged with the slot 212, and the slot 212 restricts the movement of the buckle 251. When a force is applied to the third positioning member 25, the buckle 251 overcomes the acting force of the slot 212 and can move with the third positioning member 25 towards the battery bracket 207, disengaging from the slot 212, so that the third positioning member 25 is inserted into the third positioning hole on the battery bracket 207, completing the positioning of the battery bracket 207 and the mounting portion 211.

[0126] Reference Figure 16 , in some embodiments, the second assembly component 2 further includes a fifth connecting member 29, and the fifth connecting member 29 is provided on the mounting portion 211 of the third beam 21. The fifth connecting member 29 is configured to connect the mounting portion 211 and the battery bracket 207 after the third positioning member 25 is engaged and positioned with the third positioning hole on the battery bracket 207.

[0127] In some embodiments, the second assembly component 2 further includes at least two fourth beams 22, a second lifting plate 26, and at least two second connecting plates 27.

[0128] Each of the at least two fourth beams 22 is connected to the at least two third beams 21. Each of the at least two second connecting plates 27 connects the fourth beam 22 and the second lifting plate 26.

Four of the eight second connecting plates 27 are each connected to one of the two second lifting plates 26; the other four of the eight second connecting plates 27 are each connected to the other of the two second lifting plates 26.

[0131] In some embodiments, two second hoisting plates 26 are located at both ends of the second assembly component 2.

[0132] Some embodiments of the present disclosure also provide a vehicle battery assembly method, which uses the vehicle battery assembly device provided by the embodiments of the present disclosure, and includes the following steps:

[0133] Connect at least two second beams 12 in the first assembly component 1 to at least two battery mounting beams 206 in a one-to-one correspondence respectively;

[0134] Lift the first assembly component 1 to the positions where two vehicle main beams 205 are located, and make the two first beams 11 respectively arranged in a one-to-one correspondence with the two vehicle main beams 205, so that at least two battery mounting beams 206 are located between the two vehicle main beams 205;

[0135] Connect each battery mounting beam 206 to the two vehicle main beams 205;

[0136] Disconnect the connection between at least two second beams 12 and at least two battery mounting beams 206, and remove the first assembly component 1.

[0137] In the above embodiments, in the first assembly component 1, the installation positions of at least two second beams 12 between the two first beams 11 respectively correspond to the installation positions of at least two battery mounting beams 206 between the two vehicle main beams 205 one by one, and a battery mounting beam 206 is arranged on each second beam 12; when the two first beams 11 are respectively arranged in a one-to-one correspondence with the two vehicle main beams 205, at least two battery mounting beams 206 arranged on at least two second beams 12 can be positioned between the two vehicle main beams 205 to realize the positioning of the battery mounting beam 206, and then the battery mounting beam 206 is connected to the vehicle main beam 205 through a connecting piece, that is, the connection between the battery mounting beam 206 and the vehicle main beam 205 can be realized. Through the first assembly component 1, the positioning and installation of multiple battery mounting beams 206 can be realized, with accurate positioning, simple and convenient operation, and alleviating the problems of difficult positioning of the battery mounting beam 206 and low battery swapping efficiency during the vehicle battery swapping process.

[0138] In some embodiments, the vehicle battery assembly device further includes a second assembly component 2, and the second assembly component 2 includes at least two third beams 21; each third beam 21 has a mounting portion 211 for connecting a battery bracket 207, and at least two third beams 21 are configured to be respectively arranged in a one-to-one correspondence with at least two battery mounting beams 206, so as to position the battery bracket 207 connected to the mounting portion 211 on the side of the vehicle main beam 205 away from the battery mounting beam 206, so as to prepare for the connection between the battery bracket 207 and the vehicle main beam 205; the vehicle battery assembly method further includes the following steps:

[0139] Lift the second assembly component 2 to the position where the two vehicle frame beams 205 are located, and make at least two third beams 21 respectively correspond to at least two battery mounting beams 206 one by one. Position the mounting portion 211 of the third beam 21 on the side of the vehicle frame beam 205 away from the battery mounting beam 206;

[0140] Connect the battery bracket 207 to the mounting portion 211;

[0141] Connect the battery bracket 207 to the vehicle frame beam 205;

[0142] Disconnect the connection between the third beam 21 and the battery bracket 207, and remove the second assembly component 2.

[0143] In the above embodiment, each third beam 21 has a mounting portion 211 for connecting the battery bracket 207. After at least two third beams 21 are respectively fitted to at least two battery mounting beams 206 one by one, the mounting portion 211 is located on the side of the vehicle frame beam 205 away from the battery mounting beam 206. Therefore, after the battery bracket 207 is installed on the mounting portion 211, the battery bracket 207 can be correspondingly positioned on the side of the vehicle frame beam 205 away from the battery mounting beam 206, that is, the battery bracket 207 is located at the mounting position for installing with the vehicle frame beam 205. Then, the battery bracket 207 and the vehicle frame beam 205 can be connected through a connecting piece. By using the second assembly component 2 to assist in positioning and installing the battery bracket 207, the problem of position deviation of the battery bracket 207 can be reduced, and the installation efficiency of the battery bracket 207 can be improved.

[0144] In some embodiments, an assembly hole 24 is provided on the third beam 21. In the step of connecting the battery bracket 207 to the vehicle frame beam 205, first insert an adjusting piece 208 into the gap between the battery bracket 207 and the vehicle frame beam 205 through the assembly hole 24, and then connect the battery bracket 207, the adjusting piece 208, and the vehicle frame beam 205.

[0145] In the above embodiment, after the adjusting piece 208 passes through the assembly hole 24 on the third beam 21 and is located in the gap between the vehicle frame beam 205 and the battery bracket 207, it can adjust the cumulative machining error of components such as the vehicle frame beam 205 and the battery bracket 207 in the second direction Y. Then, connecting the battery bracket 207 to the vehicle frame beam 205 can improve the connection quality between the battery bracket 207 and the vehicle frame beam 205.

[0146] On one side of the two vehicle beams 205 away from the battery mounting beam 206 (the outer side of the vehicle beam 205), battery brackets 207 are provided. The assembly of the battery brackets 207 on the outer sides of the two vehicle beams 205 is accurately positioned through the second assembly component 2. The second assembly component 2 is based on the first assembly component 1 to achieve that the coplanarity of the assembly of at least two battery mounting beams 206 meets the accuracy requirements. Taking the surfaces and positioning holes of at least two battery mounting beams 206 as the reference, the battery brackets 207 on the outer sides of the vehicle beams 205 are assisted in assembly through the second assembly component 2.

[0147] The third positioning member 25 installed on the second assembly component 2 can accurately position the battery brackets 207 on the outer sides of the vehicle beams 205 in the first direction X and the second direction Y, and then connect the battery brackets 207 through the fifth connecting member 29 to limit the position in the third direction Z.

[0148] Considering the machining errors of the vehicle beam 205 and the battery bracket 207 itself, there is a gap between the battery bracket 207 and the vehicle beam 205. Through the assembly holes 24 reserved in advance on the second assembly component 2, methods such as inserting shims can be used to adjust the mating gap, and the assembly accuracy of the battery bracket 207 in the second direction Y can be improved.

[0149] The vehicle battery assembly device and method provided by the embodiments of the present disclosure are used to position the assembly of components such as battery brackets during the process of vehicle battery swapping. The following will be combined with Figures 4 to 20 Some specific embodiments of the vehicle battery assembly device are described in detail.

[0150] Refer to Figure 5 , which is the first assembly component 1. Its main structure is a frame composed of two first beams 11 extending along the first direction X and four second beams 12 extending along the second direction Y. The second beams 12 are the beams used for fitting with the vehicle beam 205; and then they are connected and strengthened by the first connecting plate 15 with a strengthening effect in the middle and the first lifting plate 14, etc. During the use of the first assembly component 1, the second beam 12 is in contact with the bottom surface of the battery mounting beam 206 to be assembled and positioned, and is limited by the cooperation of the first positioning member 17 on the second beam 12 and the first positioning hole on the battery mounting beam 206. The adjusting component 13 of the first assembly component 1 is used to be in contact with the lower wing surface 205a of the vehicle beam 205.

[0151] Since the lower wing surface 205a of the vehicle beam 205 is uneven, the adjusting component 13 can ensure that the surfaces of the four battery mounting beams 206 are flush, without being affected by the lower wing surface 205a of the vehicle beam 205.

[0152] Refer to Figure 6 and Figure 10, the first assembly component 1 mainly fixes four battery mounting beams 206 on two vehicle girders 205. The first positioning member 17 on the first assembly component 1 is paired with the first positioning holes reserved on the battery mounting beam 206, and then the battery mounting beam 206 and the first assembly component 1 are locked and fixed through the second connecting member 16, ensuring that all four battery mounting beams 206 are accurately positioned and fixed on the first assembly component 1, and then the whole is locked and assembled with the vehicle girder 205.

[0153] Reference Figure 12 , the second assembly component 2 is used for the assembly positioning of the battery brackets 207 on the outer sides of the two vehicle girders 205. The main structure of the second assembly component 2 is a frame formed by connecting four third beams 21 extending along the second direction Y with four fourth beams 22 extending along the first direction X. The third beam 21 is a fitting cross beam for fitting with the battery mounting beam 206; and then it is connected and strengthened by the second connecting plate 27, the second lifting plate 26 and the strengthening member 27a with strengthening functions in the middle.

Finally, the two battery brackets 207 are respectively fixed with the corresponding side vehicle girders 205, and then the second assembly component 2 is removed.

[0155] Reference Figure 17 and Figure 18 , due to the assembly error in the width of the vehicle girder 205 in the second direction Y and the manufacturing error of the battery bracket 207, there will be cumulative errors in the assembly process. For the fitting gap between the battery bracket 207 and the vehicle girder 205, it can be adjusted by adding adjusting parts 208 to eliminate the cumulative errors and ensure the accuracy of the battery bracket 207 in the second direction Y during assembly.

[0156] Reference Figure 21 , through the first assembly component 1 and the second assembly component 2, the middle battery mounting beam 206 and the battery brackets 207 on both sides are accurately positioned and assembled on the vehicle girder 205 to ensure their coplanarity and positional accuracy. Then the battery swapping box 209 is installed, enabling the battery swapping box 209 to be effectively fitted and locked when assembled with the battery bracket 207.
