Description

Technical Field

[0001] The present application relates to the field of vehicle battery replacement, and in particular to a vehicle battery assembly device and method. Background Art

[0002] In some related technologies, during the process of replacing batteries in vehicles and assembling batteries into vehicles, there are problems such as low battery replacement efficiency. Summary of the invention

[0003] Some embodiments of the present application propose a vehicle battery assembly device and method for alleviating the problem of low battery replacement 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 arranged in a one-to-one correspondence with two vehicle beams respectively; and at least two second beams, both extending along a second direction and respectively connecting the two first beams, the setting positions of the at least two second beams between the two first beams respectively correspond one-to-one with the setting positions of at least two battery mounting beams between the two vehicle beams, and the at least two second beams are configured to be connected one-to-one with the at least two battery mounting beams respectively to position the at least two battery mounting beams between the two vehicle beams; the first direction intersects with the second direction.

[0005] In the above embodiment, the setting positions of at least two second beams between the two first beams correspond one-to-one with the setting positions of at least two battery mounting beams between the two vehicle beams, and a battery mounting beam is set on each second beam. In the case where the two first beams are set one-to-one with the two vehicle beams, at least two battery mounting beams set on at least two second beams can be positioned between the two vehicle beams to achieve the positioning of each battery mounting beam, and then the battery mounting beam and the vehicle beam are connected by a connecting member, that is, the connection between the battery mounting beam and the vehicle beam can be achieved. The first assembly component can be used to achieve the positioning and installation of multiple battery mounting beams, with accurate positioning and simple and convenient operation, which alleviates the problems of difficult positioning of battery mounting beams and low battery replacement efficiency during vehicle battery replacement.

[0006] In some embodiments, the first assembly component further includes an adjustment component, which is disposed at a connection between the second beam and the first beam, and is configured to adjust a 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 embodiment, the adjustment component is arranged at the connection between the second beam and the first beam. Since there are multiple second beams, multiple adjustment components are sequentially arranged along the length extension direction of the first beam. Each second beam is abutted against the vehicle beam through a second seat body. Through the floating adjustment of the elastic member, the multiple second seat bodies can form good contact with the surface of the vehicle beam at multiple contact points to disperse the force.

[0014] In some embodiments, the first connecting member is provided with an elongated hole extending along a third direction, and the adjusting assembly further comprises a limiting member, wherein the limiting member is provided on the first seat body and extends into the elongated hole.

[0015] In the above embodiment, the first connecting member sequentially connects the second base, the second beam, the first beam and the first base along the third direction. The limiting member is provided on the first base, and its relative position with the first base remains unchanged. The limiting member extends into the elongated hole provided on the first connecting member, and the length extension direction of the elongated hole is consistent with the third direction. Therefore, the first connecting member can be limited by the limiting member to prevent the first connecting member from being separated from the first base in the third direction.

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

[0017] In the above embodiment, the first positioning member cooperates with the first positioning hole on the battery mounting beam to achieve positioning of the battery mounting beam and the second beam, thereby reducing the position deviation of the battery mounting beam; after the battery mounting beam is positioned, the second beam and the battery mounting beam are connected by a second connecting member adjacent to the first positioning member, thereby reducing rework caused by the position deviation of the battery mounting beam, improving work efficiency and reducing the rework rate.

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

After the battery mounting beam is installed, the first assembly component can be removed by the first lifting plate.

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

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 the side of the vehicle beam away from the battery mounting beam. Therefore, after the battery bracket is installed on the mounting portion, the battery bracket can be positioned on the side of the vehicle beam away from the battery mounting beam, that is, the battery bracket is located at the mounting position for installation with the vehicle beam, and then the battery bracket and the vehicle beam can be connected by a connector. The method of positioning and assisting the installation of the battery bracket by the second assembly component can reduce the problem of battery bracket position deviation and improve the installation efficiency of the battery bracket.

[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 to position the mounting portion on a side of the vehicle beam away from the battery mounting beam.

[0023] In the above embodiment, a second positioning piece is provided on the third beam and is positioned with the second positioning hole on the battery mounting beam. After the second positioning piece is positioned with the second positioning hole, the mounting portion can be located on the side of the vehicle beam away from the battery mounting beam, that is, the mounting portion is located at the mounting position where the battery holder is installed with the vehicle beam. At this time, the battery holder is installed on the mounting portion, so that the battery holder can be smoothly positioned at the mounting position for installation with the vehicle beam. After that, the battery holder can be connected to the vehicle beam through a connecting piece, thereby reducing the problem of position deviation of the battery holder and improving the installation efficiency of the battery holder.

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

[0025] In the above embodiment, after the adjustment member passes through the assembly hole on the third beam, it can be located in the gap between the vehicle beam and the battery bracket, so as to adjust the accumulated processing errors of components such as the vehicle beam and the battery bracket in the second direction, thereby improving the connection quality between the battery bracket and the vehicle beam.

[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 holder for positioning.

[0027] In the above embodiment, the third positioning member cooperates with the third positioning hole to realize the positioning of the battery holder, so that the battery holder is located at the accurate position for connection with the vehicle frame, thereby reducing the position deviation of the battery holder.

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

[0029] In the above embodiment, the second connecting plate connects the fourth beam and the second lifting plate, and the second assembly component can be lifted by the second lifting plate to move the second assembly component to the position of the two vehicle beams to assist in the installation of the battery bracket. After the battery bracket is installed, the second assembly component can be removed by the second lifting plate.

[0031] In the above embodiment, in the first assembly component, the setting positions of at least two second beams between the two first beams correspond one-to-one with the setting positions of at least two battery mounting beams between the two vehicle beams, and a battery mounting beam is set on each second beam; when the two first beams are set one-to-one with the two vehicle beams, the at least two battery mounting beams set on the at least two second beams can be positioned between the two vehicle beams to achieve the positioning of the battery mounting beams, and then the battery mounting beams and the vehicle beams are connected by connecting parts, that is, the connection between the battery mounting beams and the vehicle beams can be achieved. The first assembly component can realize the positioning and installation of multiple battery mounting beams, with accurate positioning and simple and convenient operation, which alleviates the problems of difficult positioning of battery mounting beams and low battery replacement efficiency during vehicle battery replacement.

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

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

When the two first beams 11 are set in a one-to-one correspondence with the two vehicle beams 205, the at least two battery mounting beams 206 set on the at least two second beams 12 can be positioned between the two vehicle beams 205 to achieve the positioning of each battery mounting beam 206, and then the battery mounting beam 206 and the vehicle beam 205 are connected by a connecting member, that is, the connection between the battery mounting beam 206 and the vehicle beam 205 can be achieved. The first assembly component 1 can realize the positioning and installation of multiple battery mounting beams 206, with accurate positioning and simple and convenient operation, which alleviates the problems of difficult positioning of the battery mounting beam 206 and low battery replacement efficiency during vehicle battery replacement.

[0062] refer to Figure 6 In some embodiments, the first assembly component 1 further includes an adjustment component 13 , which is disposed at a connection between the second beam 12 and the first beam 11 , and is configured to adjust a gap between the second beam 12 and the first beam 11 .

[0063] refer to Figure 6 and Figure 7 Since 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.

[0064] 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 .

[0065] 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.

[0066] refer to Figure 8 and Fig. 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 .

[0067] The first base 131 is fixedly disposed on a side of the first beam 11 away from the second beam 12 .

[0068] The second base 132 is movably disposed on a side of the second beam 12 away from the first beam 11 .

[0069] 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 .

[0070] The elastic member 133 is disposed on the first connecting member 134 and is located between the first base body 131 and the second base body 132 .

[0071] In the above embodiment, the first seat body 131 is fixedly arranged on the side of the first beam 11 away from the second beam 12, and the relative positions of the first seat body 131 and the first beam 11 remain unchanged. The second seat body 132 is movably arranged on the side of the second beam 12 away from the first beam 11, and there is a space for movement between the second seat body 132 and the second beam 12. The battery mounting beam 206 is mounted on the second beam 12, and the gravity of the battery mounting beam 206 causes the second beam 12 to be arranged close to the vehicle beam 205. In the case that the surface of the vehicle beam 205 is uneven, 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 first beam 11 drives the first seat body 131 to move toward the second seat body 132 due to the gravity, 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 will be 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 concave portion on the surface of the vehicle beam 205, the second beam 12 covers the concave portion, and the force of the elastic member 133 enables the second beam 12 to be pressed toward the concave portion, thereby maintaining the contact between the second beam 12 and the vehicle beam 205. By providing 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.

[0075] In the above embodiment, the adjustment component 13 is arranged at the connection between the second beam 12 and the first beam 11. Since there are multiple second beams 12, multiple adjustment components 13 are sequentially arranged along the length extension direction of the first beam 11. Each second beam 12 is abutted against the vehicle beam 205 through a second seat body 132. Through the floating adjustment of the elastic member 133, the multiple second seat bodies 132 can form good contact with the surface of the vehicle beam 205 at multiple contact points to disperse the force.

[0076] In some embodiments, the elastic member 133 includes an elastic component such as a spring.

[0077] In some embodiments, the first connecting member 134 is provided with an elongated hole 135 extending along the third direction Z. The adjusting assembly 13 further includes a stopper 136 . The stopper 136 is provided on the first base 131 and extends into the elongated hole 135 .

[0078] In the above embodiment, the first connecting member 134 sequentially connects the second base 132, the second beam 12, the first beam 11 and the first base 131 along the third direction Z. The limiting member 136 is provided on the first base 131, and its relative position with the first base 131 remains unchanged. The limiting member 136 extends into the elongated hole 135 provided on the first connecting member 134, and the length extension direction of the elongated hole 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 being separated from the first base 131 in the third direction Z.

[0116] Battery brackets 207 are provided on the side of the two vehicle beams 205 away from the battery mounting beam 206 (outside the vehicle beam 205). The assembly of the battery brackets 207 on the outside of the two vehicle beams 205 is accurately positioned by the second assembly component 2. The second assembly component 2 is based on the first assembly component 1 to achieve the coplanarity of at least two battery mounting beams 206 to meet the precision requirements.

[0118] Considering the processing errors of the vehicle frame 205 and the battery bracket 207 themselves, there is a gap between the battery bracket 207 and the vehicle frame 205. Through the assembly hole 24 reserved in advance on the second assembly component 2, the matching gap can be adjusted by adding a pad or the like to improve the assembly accuracy of the battery bracket 207 in the second direction Y.

[0119] The vehicle battery assembly device and method provided in the embodiment of the present disclosure are used to position the assembly of components such as a battery bracket during the process of replacing the battery of the vehicle. Figures 4 to 20 Some specific embodiments of the vehicle battery assembly device are described in detail.

[0120] refer to Figure 5 , is the first assembly component 1, whose main structure is a frame composed of two first beams 11 extending in the first direction X and four second beams 12 extending in the second direction Y. The second beams 12 are used to fit with the vehicle beam 205; and then connected and strengthened by the first connecting plate 15 and the first hanging plate 14 in the middle with a reinforcing function. During the use of the first assembly component 1, the second beam 12 fits with the bottom surface of the assembled and positioned battery mounting beam 206, and the first positioning member 17 on the second beam 12 cooperates with the first positioning hole on the battery mounting beam 206 to limit the position. The adjustment component 13 of the first assembly component 1 is used to fit with the lower wing surface 205a of the vehicle beam 205.

[0121] Since the lower wing surface 205 a of the vehicle beam 205 is uneven, the surfaces of the four battery mounting beams 206 can be ensured to be flush by adjusting the assembly 13 and not be affected by the lower wing surface 205 a of the vehicle beam 205 .

[0122] refer to Figure 6 and Fig.10 The first assembly component 1 is mainly used to fix the four battery mounting beams 206 on the two vehicle beams 205. The first positioning member 17 on the first assembly component 1 is matched with the first positioning hole reserved on the battery mounting beam 206, and then the battery mounting beam 206 is locked and fixed to the first assembly component 1 through the second connecting member 16, ensuring that the 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 beam 205.

[0123] refer to Fig.12, is the second assembly component 2, which is used for assembling and positioning the battery bracket 207 outside the two vehicle beams 205. The main structure of the second assembly component 2 is a frame formed by four fourth beams 22 extending along the first direction X connecting four third beams 21 extending along the second direction Y. The third beam 21 is a fitting cross beam used to fit with the battery mounting beam 206; it is then connected and strengthened by a second connecting plate 27 with a reinforcing function in the middle, a second hanging plate 26 and a reinforcing member 27a.

[0124] refer to Fig.13 and Fig.14 The second assembly component 2 is first positioned with the battery mounting beam 206 by the second positioning member 23, and fixed with the battery mounting beam 206 by the fourth connecting member 28, so as to ensure that the fitting beam of the second assembly component 2, i.e., the third beam 21, is flush with the assembled battery mounting beam 206. Fig.15 and Fig.16 , accurately position the two battery brackets 207 with the second assembly component 2 through the third positioning member 25, and then fix the two battery brackets 207 to the second assembly component 2 through the fifth connecting member 29. Finally, fix the two battery brackets 207 to the vehicle beam 205 on the corresponding side, and then remove the second assembly component 2.

[0125] refer to Fig.17 and Fig.18 Due to the assembly error of the width of the vehicle beam 205 in the second direction Y and the processing and manufacturing error of the battery bracket 207, there will be cumulative errors in the assembly process.
