Description

Technical Field

[0001] The present invention relates to the technical field of power battery systems, and in particular to a battery pack side beam and a vehicle. Background Art

[0002] New energy vehicles have become a strongly supported new energy industry. As a core component of new energy vehicles, the power battery pack provides power for the entire vehicle. To ensure the overall strength and rigidity of the power battery pack, the power battery pack side beam, as a key component of the power battery pack, not only effectively protects the battery and supports the power battery pack, but also provides a fixed mounting point for the power battery pack.

[0003] Since the positions of the fixed mounting points of the battery pack side beams of different models are different, when a power battery pack needs to be installed on a certain model, a power battery pack side beam that matches the position of the mounting point needs to be developed according to the adaptability of the model. In order to adapt to different models, manufacturers need to develop a variety of power battery pack side beams, but this will increase the development cost of the power battery pack side beams.

[0032] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0033] A battery pack side beam shown in an embodiment of the present invention includes a side beam body, a mounting bracket and a limiter. The interior of the side beam body is a hollow cavity. The surface of the hollow cavity is provided with a track groove along the length direction of the side beam body, and a limiter groove connected to the track groove. The limiter can slide between the track groove and the limiter groove. When the limiter is located in the limiter groove, the limiter will be relatively fixed in the limiter groove. At the same time, the limiter can slide between the track groove and the limiter groove. When the limiter is located in the track groove, the limiter can move along the length direction of the side beam body, and the limiter is connected to the mounting bracket. At the same time, the mounting bracket passes through the hollow cavity and is connected to the side beam mounting point of the vehicle body. When the limiter moves along the length direction of the side beam body, the mounting bracket also moves with the movement of the limiter. The flexible movement of the limiter enables the flexible movement of the mounting bracket position. Due to the adjustability of the mounting bracket position, when the mounting bracket is connected to the vehicle body, it can also be matched and adjusted according to the different side beam mounting point positions of different vehicle models, so that the battery pack side beam of the embodiment of the present invention meets the installation requirements of power battery pack side beams of various vehicle models, and is no longer limited to a certain customized power battery pack side beam, thereby reducing the development cost of the power battery pack side beam and solving the problem that the existing battery pack side beam cannot adapt to different vehicle models.

[0034] Furthermore, on this basis, the limit slot is connected to the track slot, and the two are arranged in parallel. The limit member can slide between the limit slot and the track slot, that is, the limit member can move in a direction parallel to the sliding direction from the track slot to the limit slot, which can realize the movement of the limit member in two different directions. After the limit member enters the limit slot, it is locked, and the mounting bracket is also fixed accordingly, which can realize the fixing of the mounting bracket at a certain point along the sliding path along the length of the side beam body. This prevents the unfixed limit member from shaking due to vehicle bumps, causing the mounting bracket to shift in position and affecting the stability of the connection between the mounting bracket and the vehicle body.

[0035] Another object of the present invention is to provide a vehicle to solve the problem that existing battery pack side beams cannot be adapted to different vehicle models.

[0036] The advantages of the vehicle and the above-mentioned battery pack side beam over the existing technology are the same and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0056] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0057] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0058] Reference Figures 1 to 8 The present invention provides a battery pack side beam, which includes a side beam body 1, a mounting bracket 2 and a limit member 3; the interior of the side beam body 1 is a hollow cavity 11, and the surface of the hollow cavity 11 is provided with a rail groove 111 along the length direction of the side beam body 1, and a limit groove 112 connected to the rail groove 111; the limit member 3 is connected to the mounting bracket 2, and the limit member 3 is slidable between the rail groove 111 and the limit groove 112. The mounting bracket 2 extends from the hollow cavity 11 to be connected to the side beam mounting point of the vehicle body. When the limit member 3 is located in the limit groove 112, the limit member 3 is in a locked state.

[0059] Specifically, the battery pack side beam provided by the present invention includes a side beam body 1, a mounting bracket 2 and a limiter 3, Figure 1 and Figure 2 As shown in the diagram, the side beam body 1 has a hollow accommodating cavity, which is a hollow cavity 11 that can accommodate the limiter 3, and the limiter 3 can move in the hollow cavity 11. The hollow cavity 11 is along the length direction of the side beam body 1, that is, Figure 1 In the X-axis direction shown in FIG, the surface of the hollow cavity 11 is provided with a track groove 111 and a limit groove 112. Further explanation: the surface of the hollow cavity 11 refers to the surface inside the hollow cavity 11. The track groove 111 and the limit groove 112 are connected, which means that the track groove 111 and the limit groove 112 are on the same side and are distributed in parallel. The length of the track groove 111 and the limit groove 112 can allow the limit member 3 to be positioned along the inner side. Figure 1 The limiting member 3 can slide between the track groove 111 and the limiting groove 112. When the limiting member 3 is located in the limiting groove 112, the limiting member 3 is in a locked state. That is, the limiting groove 112 plays a role in fixing the position of the limiting member 3. When the limiting member 3 is in the track groove 111, the track groove 111 does not have the conditions to limit the movement of the limiting member 3. The limiting member 3 can move along the track groove 111. Figure 1 The position-limiting member 3 can be arbitrarily slid in the X-axis direction as shown in FIG. 3 . When the position-limiting member 3 needs to be locked, the position-limiting member 3 only needs to be slid into the position-limiting groove 112 to fix the position-limiting member 3 .

[0060] In addition, the limiting member 3 is connected to the mounting bracket 2, and the mounting bracket 2 extends from the hollow cavity 11 to fix the battery pack. It is further explained that one side of the limiting member 3 is connected to the mounting bracket 2, and the mounting bracket 2 is not entirely located in the hollow cavity 11. The mounting bracket 2 can pass through the hollow cavity 11 and extend to the outside of the side beam body 1 to connect with the side beam mounting point of the vehicle body. The mounting bracket 2 is provided with a connection point for connecting with the vehicle body. In the embodiment of the present invention, referring to Figure 7 and Figure 8 , Figure 8 This is a structural diagram of an embodiment of the present invention in which a mounting bracket 2 is installed on a side beam body 1. There is a bolt mounting hole on the mounting bracket 2 that is connected to the vehicle body and the limiter 3. The mounting bracket 2 is connected to the vehicle body and the limiter 3 through the bolt mounting hole. The bolt connection method can be convenient for the staff to operate, and avoids time-consuming and labor-intensive complex processes such as welding. It is worth noting that since the mounting bracket 2 extends from the hollow cavity 11 and is connected to the side beam mounting point of the vehicle body, and the mounting bracket 2 moves along the length direction of the side beam body 1 with the limiter 3, the side beam on the side where the mounting bracket 2 extends out of the hollow cavity 11 should also have a channel that can accommodate the mounting bracket 2 moving along the length direction of the side beam body 1, combined with Figure 1 It can be seen that in order to ensure that the limiting member 3 moves along the track groove 111 Figure 1 The length of the channel should be consistent with the length of the track groove 111, so as to ensure that the limiter 3 can move along the X-axis direction. Figure 1 The hole should be parallel to the track groove 111, and the hole passes through the shell of the side beam body 1 and communicates with the hollow cavity 11. Figure 1 The position of any point can be fixed on the moving line in the X-axis direction. Figure 1 There should be a limit groove 112 on the moving line in the X-axis direction to achieve the locking function.

[0061] Through the above design, the limiter 3 is connected to the mounting bracket 2, and the mounting bracket 2 is connected to the side beam mounting point of the vehicle body. When the limiter 3 moves along the length direction of the side beam body 1 in the track groove 111, the mounting bracket is also driven to move along the length direction of the side beam body 1 along with the limiter 3, thereby ensuring the mobility of the mounting point position of the battery pack side beam. Since the side beam mounting point positions required by different vehicle models are different, and the mounting points of existing battery pack side beams cannot be moved, the existing battery pack side beams cannot match a variety of vehicle models with side beam mounting points in different positions. The battery pack side beam in the embodiment of the present invention can flexibly adjust the mounting bracket position and can be connected to different side beam mounting points of different vehicle models, so that it meets the installation requirements of most power battery pack side beams, is no longer limited to a certain customized power battery pack side beam, can also reduce the development cost of the power battery pack side beam, and solves the problem that the existing battery pack side beam cannot adapt to different vehicle models. Secondly, on this basis, the track groove 111 and the limit groove 112 are connected and distributed in parallel, so that the limit member 3 can slide between the track groove 111 and the limit groove 112, and move along the direction parallel to the track groove 111 to the limit groove 112 to realize the movement of the limit member 3 in two different directions, thereby increasing the adjustability of the movement direction of the limit member 3. When the limit member 3 enters the limit groove 112 to realize the locking function, it also realizes the fixation of the mounting bracket at a certain point on the sliding line along the length direction of the side beam body 1, thereby avoiding the limit member 3 from shaking due to bumpy road conditions during vehicle operation or airflow inrush during driving, causing the mounting bracket to be offset in position, thereby affecting the stability of the connection between the mounting bracket and the vehicle body.

[0062] Optionally, refer to Figures 1 to 8 The track groove 111 and the limiting groove 112 are arranged in parallel, the limiting groove 112 is provided with a first protruding tooth 1121, and the limiting member 3 is provided with a second protruding tooth 31; when the limiting member 3 slides from the track groove 111 to the limiting groove 112, the first protruding tooth 1121 engages with the second protruding tooth 31, and the limiting member 3 is in a locked state; when the limiting member 3 is in the track groove 111, the first protruding tooth 1121 is separated from the second protruding tooth 31, and the limiting member 3 can be translated along the length direction of the side beam body 1.

[0063] Specifically, the track groove 111 and the limiting groove 112 are located on the same side and are arranged in parallel. The lengths of the track groove 111 and the limiting groove 112 allow the limiting member 3 to be positioned along the inner edge of the track groove 111 and the limiting groove 112. Figure 1, and the length range of the limiting groove 112 should meet the requirement that when the limiting member 3 slides from any position of the track groove 111 to the limiting groove 112, there is a limiting groove 112 for receiving the limiting member 3 to realize the locking state. The limiting groove 112 is provided with a first protruding tooth 1121, and the limiting member 3 is provided with a second protruding tooth 31. The shapes of the first protruding tooth 1121 and the second protruding tooth 31 match and can be engaged. When the first protruding tooth 1121 and the second protruding tooth 31 are engaged, the limiting member 3 is located on the limiting groove 112. The limiting member 3 can slide between the track groove 111 and the limiting groove 112. That is to say, since the track groove 111 and the limiting groove 112 are distributed side by side, the direction in which the limiting member 3 slides between the track groove 111 and the limiting groove 112 is along the width direction of the side beam body 1, that is, Figure 1 The Y-axis direction is shown in .

[0064] Reference Figures 2 to 5 When the limiting member 3 slides from the track groove 111 to the limiting groove 112, combined with Figure 2 As shown in the figure, the limiting member 3 is in the limiting groove 112. Since the limiting groove 112 is provided with a first protruding tooth 1121, the first protruding tooth 1121 and the second protruding tooth 31 can mesh with each other, the limiting member 3 will be restricted in movement due to the engagement of the protruding teeth when in the limiting groove 112, so that the limiting member 3 is in a locked state. The locked state here means that the limiting member 3 cannot be moved. Figure 1 The movement in the X-axis and Y-axis directions shown is also Figure 2 When the stopper 3 is in the track groove 111, the movement in the Y-axis direction is shown in FIG. Figure 3 As shown in the diagram, since there is no structure similar to a convex tooth on the track groove 111, it does not have the function of limiting the limit member 3. At this time, the first convex tooth 1121 is separated from the second convex tooth 31. Therefore, when the limit member 3 is in the track groove 111 and moves along the length direction of the side beam body 1, it will not be restricted by the track groove 111. The limit member 3 can move arbitrarily in the length direction of the side beam body 1.

[0065] On this basis, the embodiment of the present invention is further provided with a limiting groove 112 of the first protruding tooth 1121, and a second protruding tooth 31 matching the first protruding tooth 1121 is provided on the limiting member 3, so that when the limiting member 3 slides from the track groove 111 to the limiting groove 112, the first protruding tooth 1121 and the second protruding tooth 31 engage with each other, and the position of the limiting member 3 is limited by the limiting groove 112, so that the limiting member 3 is in a locked state, so that the limiting member 3 can be relatively fixed at any point on the moving line along the length direction of the side beam body 1, ensuring the position fixability of the mounting bracket 2 connected to the limiting member 3, and avoiding the situation in which the unfixed limiting member 3 shakes due to the bumping of the vehicle during the driving of the vehicle, causing the mounting bracket 2 to shift in position, affecting the structural stability of the connection between the power battery pack side beam and the vehicle.

[0066] It is noteworthy that the engagement structure between the stopper 3 and the stopper groove 112 employed in the embodiment of the present invention allows the stopper 3 to move freely along the length of the side beam body 1. Furthermore, in the sliding state, the stopper 3 is not restricted by the second protruding teeth 31, enabling flexible adjustment of the position of the stopper 3. When the stopper 3 enters the locked state, it can also be easily disengaged. Furthermore, the meshing structure is simple to manufacture, and the engagement between the stopper 3 and the stopper groove 112 is easy to operate. Compared to interference fit or bolt-limited structures, it requires less machining precision and is easier to disassemble, offering greater practical advantages.

[0067] Optionally, refer to Figures 1 to 10 The limiting member 3 is a circular roller; the limiting member 3 is rotatably connected to the mounting bracket 2, and the outer peripheral surface of the limiting member 3 is provided with a second protruding tooth 31; the side beam body 1 includes a first surface 12 and a second surface 13 that are parallel to each other, and the first surface 12 and the second surface 13 are both provided with a limiting groove 112; when the limiting member 3 slides from the track groove 111 to the limiting groove 112, the limiting member 3 is located between the limiting groove 112 of the first surface 12 and the limiting groove 112 of the second surface 13.

[0068] Specifically, combined Figure 9 and Figure 10 As can be seen from the diagram, the limiting member 3 of the embodiment of the present invention can be a circular roller, and the outer peripheral surface of the limiting member 3 is provided with a second protruding tooth 31. The limiting member 3 is connected to the mounting bracket 2, and the mounting bracket 2 is connected to the mounting point of the side beam of the vehicle body. The limiting member 3 is rotatably connected to the mounting bracket 2, which means that when the limiting member 3 is rotated along the Figure 1 When the mounting bracket 2 moves in the X-axis direction, the mounting bracket 2 does not rotate due to the circumferential movement of the limiter 3. The mounting bracket 2 always remains stationary during the movement of the limiter 3. Therefore, the connection between the limiter 3 and the mounting bracket 2 should be a rotatable shaft-hole matching relationship, thereby ensuring the relative stability of the mounting bracket 2. Figure 6 It can be seen that the side beam body 1 includes a first surface 12 and a second surface 13 that are parallel to each other. It should be noted here that a track groove 111 and a limit groove 112 are provided on the first surface 12. Similarly, a track groove 111 and a limit groove 112 are also provided on the second surface 13 opposite to the first surface 12, and the track grooves 111 and the limit grooves 112 on the two surfaces are also arranged opposite to each other and have the same shape, size and length.

[0069] The first protruding teeth 1121 provided in the limiting groove 112 are adapted to mesh with the second protruding teeth 31 on the outer peripheral surface of the limiting member 3. When the limiting member 3 slides from the track groove 111 into the limiting groove 112, the limiting member 3 is located between the limiting groove 112 of the first surface 12 and the limiting groove 112 of the second surface 13. The clamping relationship between the second protruding teeth 31 and the first protruding teeth 1121 makes the limiting member 3 just fixed between the two limiting grooves, thereby realizing the limiting member 3 being in the position. Figure 2 The position in the Y-axis direction is fixed, so that the limiting member 3 is in a locked state.

[0070] It is worth noting that, combined with Figure 9 It can be seen that when the limiting member 3 is a circular roller, the first surface 12 and the second surface 13 are both provided with first protruding teeth 1121 to ensure that the limiting member 3 enters the limiting groove 112 and engages and locks. In the embodiment of the present invention, the limiting member 3 is a circular roller, which facilitates the sliding of the limiting member 3 within the track groove 111, making it easier for workers to move the limiting member 3. In addition, the use of the protruding teeth on the circular roller to cooperate with the limiting groove 112 makes the engagement more secure, thereby enhancing the fixing function of the limiting member 3 when locked.

[0071] Optionally, refer to Figure 11 and Figure 12 The limiting member 3 is a rectangular slider; the limiting member 3 is fixedly connected to the mounting bracket 2, and a second protruding tooth 31 is provided on the surface of the limiting member 3 in contact with the limiting groove 112; the side beam body 1 includes a first surface 12 and a second surface 13 that are parallel to each other, and the first surface 12 or the second surface 13 is provided with a limiting groove 112.

[0072] Specifically, in addition to the above-mentioned circular roller, the present invention proposes another embodiment of the limiting member 3. When the limiting member 3 is a rectangular slider, the limiting member 3 is connected to the mounting bracket 2, and the mounting bracket 2 is connected to the side beam mounting point of the vehicle body. Figure 1 When the mounting bracket 2 and the position limiting member 3 move in the X-axis direction, the connection between the position limiting member 3 and the mounting bracket 2 can be a fixed point, thereby ensuring the relative stability of the mounting bracket 2. Figure 11 As can be seen from the diagram, when the limiting member 3 is a rectangular slider, the limiting member 3 only needs to be provided with the second protruding teeth 31 on the surface in contact with the limiting groove 112 to lock the limiting member 3 in the limiting groove 112. It is not necessary to provide the second protruding teeth 31 on multiple surfaces of the limiting member 3. Moreover, the limiting groove 112 only needs to be provided on the surface in contact with the limiting member 3, which can be the first surface 12 or the second surface 13. The present invention is not limited to this, and a combination can be selected according to actual circumstances.

[0073] It is worth noting that, referring to Figure 12 , Figure 12In the embodiment of the present invention, the limiting member 3 is a rectangular slider. When the limiting member 3 is in the track groove 111, it moves along the track groove 111. Figure 1 In the plan view viewed along the Y-axis, since the second protruding tooth 31 is provided on one side of the stopper 3, to ensure that the stopper 3 is not obstructed from sliding within the track groove 111, the track groove 111 must be able to accommodate the second protruding tooth 31. Compared to the solution in which the stopper 3 is a circular roller, this embodiment simplifies the structure of the stopper and fixation, and the stopper groove 112 only needs to be provided with a protruding tooth on one side to achieve the locking function.

[0074] Optionally, refer to Figures 1 to 7 The battery pack side beam also includes an elastic member 4 and a support member 5; the elastic member 4 is arranged between the support member 5 and the limit member 3, one end of the elastic member 4 is fixedly connected to the support member 5, and the other end of the elastic member 4 is fixedly connected to the limit member 3, and the elastic member 4 is used to push the limit member 3 to slide into the limit groove 112; the hollow cavity 11 is provided with a slide groove 113 along the length direction of the side beam body, and part of the support member 5 is embedded in the slide groove 113 and moves along the length direction of the side beam body.

[0075] Specifically, combined Figures 2 to 5 As shown in the diagram, the battery pack side beam also includes an elastic member 4 and a support member 5. The elastic member 4 is a component with elastic force, such as a spring, elastic silicone, etc. The elastic member 4 is arranged between the support member 5 and the limit member 3. One end of the elastic member 4 is fixedly connected to the support member 5, and the other end of the elastic member 4 is fixedly connected to the limit member 3. The limit member 3 slides between the track groove 111 and the limit groove 112 through the elastic member 4. Figure 2 When the force in the Y-axis direction is applied, the limiting member 3 can be moved into the track groove 111 along with the squeezed mounting bracket 2. At this time, the deformation of the elastic member 4 is large and it is in a heavily compressed state, as shown in FIG. Figure 3 When the staff is mounting the bracket 2 Figure 2 When no force is applied in the Y-axis direction as shown in FIG, the elastic member 4 generates a pushing force in the Y-axis direction on the limit member 3 by virtue of its own elastic force, forcing the limit member 3 to slide into the limit groove 112. At this time, the deformation of the elastic member 4 is small and is in a lightly compressed state, as shown in FIG. Figure 2 It is further explained that when the elastic member 4 pushes the limiting member 3 to the limiting groove 112, the limiting member 3 is meshed with the limiting groove 112 through the convex teeth. At the same time, in order to enhance the stability of the limiting member 3 in the limiting groove 112, the end of the limiting member 3 connected to the mounting bracket 2 is in contact with the side beam body 1. The surface of the side beam body 1 blocks the limiting member 3, preventing the limiting member 3 from popping out of the hollow cavity 11 due to excessive thrust of the elastic member 3, so that the range of movement of the limiting member 3 is always inside the hollow cavity 11.

[0076] The hollow cavity 11 is along the length direction of the side beam body, that is, Figure 1 As shown, a slide groove 113 is provided in the X-axis direction, and a portion of the support member 5 is embedded in the slide groove 113 and moves along the X-axis direction. Further explanation is given, because one end of the elastic member 4 is fixedly connected to the support member 5, and the other end of the elastic member 4 is fixedly connected to the limit member 3, when the limit member 3 can move along the X-axis direction, since the limit member 3, the elastic member 4, and the support member 5 are fixedly connected to each other, the support member 5 must also move with the movement of the limit member 3. Furthermore, a portion of the support member 5 is embedded in the slide groove 113. When the limit member 3 moves along the X-axis direction, the portion of the support member 5 moves along the X-axis direction within the slide groove 113 with the limit member 3. By providing the support member 5 connected to the elastic member 4, while ensuring that the limit member 3 can move in the Y-axis direction, it also prevents the elastic member 4 from causing the entire sliding structure to shake. Therefore, providing the support member 5 enhances the stability of the entire sliding structure.

[0077] Optionally, refer to Figure 7 The elastic member 4 is a spring, the support member 5 includes a support body 51 and a first support boss 52 fixed to one side of the support body 51, and a second support boss 32 is provided on the side of the limit member 3 facing away from the mounting bracket 2; one end of the elastic member 4 is sleeved and fixed on the first support boss 52, and the other end of the elastic member 4 is sleeved and fixed on the second support boss 32.

[0078] Specifically, Figure 7 This is an exploded schematic diagram of the mounting bracket, the limiting member, the elastic member and the supporting member according to the embodiment of the present invention, combined with Figure 7 As can be seen from the diagram, the elastic member 4 of the embodiment of the present invention is a spring, and the support member 5 includes a support body 51 and a first support boss 52. The first support boss 52 is fixed to one side of the support body 51 and is fixedly connected to the support body 51. A second support boss 32 is provided on the side of the limit member 3 away from the mounting bracket 2. The second support boss 32 is also fixedly connected to the limit member 3. The two ends of the elastic member 4 are respectively sleeved and connected with the first support boss 52 and the second support boss 32, and the first support boss 52 and the second support boss 32 are both adapted to fit the elastic member 4. In the embodiment of the present invention, the first support boss 52 and the second support boss 32 are both cylindrical bosses, and the two are the same size and opposite in position. The holes at both ends of the elastic member 4 just wrap around the first support boss 52 and the second support boss 32. Through the first support boss 52 and the second support boss 32, the elastic member 4 connects the support member 5 and the limit member 3 to each other along the Figure 7 The stability of the connection among the limiting member 3, the elastic member 4 and the supporting member 5 is enhanced on the same axis in the Y-axis direction.

[0079] Optionally, refer to Figures 2 to 5 , the diameter of the support body 51 is greater than the opening width of the slide groove 113.

[0080] Specifically, the first support boss 52 is fixed to one side of the support body 51 and is fixedly connected to the support body 51. The first support boss 52 is also connected to the elastic member 4. When the elastic member 4 rebounds from the heavy compression state to the light compression state, the elastic force of the elastic member 4 pushes the limit member 3 while also exerting a certain pushing force on the support body 51. Figures 2 to 5 As can be seen from the diagram, since the diameter of the support body 51 is larger than the opening width of the slide groove 113, that is, when the limit member 3 slides between the track groove 111 and the limit groove 112, the support body 51 is always in contact with the side beam body 1, and the surface of the side beam body 1 has a blocking effect on the support body 51, preventing the support body 51 from popping out of the hollow cavity 11 due to excessive thrust of the elastic member 3 and the diameter of the support body 51 being smaller than the opening width of the slide groove 113, so that the range of movement of the support body 51 is always inside the hollow cavity 11.

[0081] Optionally, refer to Figures 1 to 7 The support member 5 also includes a cylindrical guide boss 53 fixed to the other side of the support body 51; a third protruding tooth 1131 is provided in the slide groove 113, and a fourth protruding tooth 531 is provided on the circumferential surface of the guide boss 53. The guide boss 53 is embedded in the slide groove 113, and the third protruding tooth 1131 is engaged with the fourth protruding tooth 531.

[0082] Specifically, combined Figures 1 to 7 As shown in the schematic diagram, the support member 5 also includes a cylindrical guide boss 53 fixed to the other side of the support body 51, and a fourth convex tooth 531 is provided on the outer circumferential surface of the guide boss 53. At the same time, a third convex tooth 1131 is provided in the slide groove 113. When the support member 5 moves along the limit member 3 Figure 1 When moving in the X-axis direction as shown, the third protruding tooth 1131 meshes with the fourth protruding tooth 531, and the guide boss 53 is embedded in the slide groove 113 to move in the X-axis direction, thereby driving the support member 5 to move along with the limit member 3. In addition, the engagement of the fourth protruding tooth 531 of the guide boss 53 with the third protruding tooth 1131 in the slide groove 113 also ensures that the support member 5 does not shift in position during the sliding process, thereby enhancing the structural stability of the support member 5 when moving in the slide groove 113.

[0083] It is worth noting that the third protruding tooth 1131 is only provided on one side of the slide groove 113 and not on the other side. This ensures that when the guide boss 53 moves in the slide groove 113, it only has the function of moving, and does not cause the guide boss 53 to be stuck in the slide groove 113 and unable to move.

[0084] Optionally, refer to Figures 1 to 13The guide boss 53 is fixedly connected to the side of the support body 51 with a balance bar 54; the side beam body 1 is provided with a balance guide rail 14, and the balance guide rail 14 is located on the side of the slide groove 113 away from the support body 51; the balance guide rail 14 is pressed onto the top of the balance bar 54, and the balance bar 54 is slidably connected to the balance guide rail 14.

[0085] Specifically, the guide boss 53 is fixedly connected to the side away from the support body 51 with a balance rod 54, and the side beam body 1 is provided with a balance guide rail 14. Figures 1 to 13 As can be seen from the diagram, the balancing guide rail 14 is located on the side of the chute 113 away from the support body 51, which means that the balancing bar 54 and the balancing guide rail 14 are on the same side and are both located on the side of the chute 113, and this side is the side of the chute 113 away from the support body 51. The balancing bar 54 and the balancing guide rail 14 are adapted to slide. When the guide boss 53 moves within the chute 113, the balancing bar 54 is fixedly connected to the guide boss 53. As the guide boss 53 rotates, the balancing bar 54 also moves on the track of the balancing guide rail 14. In order to ensure that the balancing bar 54 does not roll over or deviate from the position when the guide boss 53 rotates, and does not cause the support member 5 and the limit member 3 to deviate from the position, the balancing guide rail 14 is pressed against the top of the balancing bar 54, providing a certain guarantee for the position of the balancing bar 54 and the balance of the support member 5.

[0086] Optionally, refer to Figures 1 to 16 The side beam body 1 includes multiple frames 15 and end covers 16. The multiple frames 15 are connected in sequence to form a rectangular hollow cavity 11. The two opposite surfaces of the hollow cavity 11 have through openings. An end cover 16 is provided at each opening position, and the end cover 16 is detachably connected to the frame 15.

[0087] Specifically, the side beam body 1 includes a plurality of frames 15 and end covers 16, and the plurality of frames 15 and end covers 16 constitute the outer shell of the hollow cavity 11. The frames 15 and the end covers 16 are connected to each other through the card slots 161. The connection method is simple and convenient, does not require welding or other fixed connections, and is easy to disassemble. The frames 15 and the end covers 16 of the present invention are vertically connected to each other, and together define a rectangular accommodating cavity with a hollow structure, which is the hollow cavity 11, and can accommodate part of the structure of the limiter 3, the elastic member 4 and the support member 5 to move therein. The distribution direction of the frame 15 is parallel to the length direction of the side beam body 1. The plurality of frames 15 of the embodiment of the present invention are vertically connected to each other to form a rectangular shell with through openings at both ends. The two opposite surfaces in the hollow cavity 11 have through openings, and the two opposing frames 15 are the same in shape, size and length. An end cover 16 is provided at each opening position, that is, the end covers 16 are the two end faces of the rectangular shell. Combined Figure 1As shown in the figure, the two end covers 16 are also arranged opposite to each other, with the same shape and size, and the end covers 16 are provided with reinforcing patterns, which can play a role in strengthening the strength of the end covers 16. A hollow cavity 11 is composed of multiple frames 15 and multiple end covers 16, and part of the structure of the limiter 3, the elastic member 4 and the support member 5 moves in the hollow cavity 11 formed by the mutual connection of the two. The airflow or dust of the vehicle is not easy to enter the hollow cavity 11 due to the blocking effect between the frame 15 and the end cover 16, which reduces the air damping while protecting the sliding component and reduces the interference of the external environment.

[0088] Optionally, refer to Figure 14 , a plurality of limiting grooves 112 are provided at intervals along the length direction of the side beam body 1, and the plurality of limiting grooves 112 are parallel to the track groove 111; when the limiting member 3 is located in any limiting groove 112, the limiting member 3 is in a locked state.

[0089] Specifically, in addition to the above embodiments, the present invention also provides an embodiment: Figure 14 This is a top view of the embodiment of the present invention when the limiting member 3 moves in the track groove 111 and is fixed in the limiting groove 112. Figure 14 As can be seen from the diagram, the solid line limiter 3 represents the scene when the limiter 3 is sliding in the track groove 111, and the dotted line limiter 3 represents the scene when the limiter 3 is locked in the limit groove 112. Figure 14 As shown in the figure, a plurality of limiting grooves 112 are provided in the X-axis direction. The plurality of limiting grooves 112 are parallel to the track groove 111, which means that the plurality of limiting grooves 112 are distributed in a direction parallel to the track groove 111. When the limiting member 3 is in any limiting groove 112, the limiting member 3 can be locked and fixed. The number of limiting grooves 112 is not limited here and can be selected according to actual conditions. By providing a plurality of limiting grooves 112 in parallel with the track groove 111, the selectivity of the fixed position of the limiting member 3 can be achieved. Compared with the above embodiment, the embodiment of the present invention can set the limiting grooves 112 according to the actual required fixed point position, which can reduce process costs and increase more selectivity.

[0090] An embodiment of the present invention also provides a vehicle, which includes any of the aforementioned battery pack side beams. In a vehicle equipped with the above-mentioned battery pack side beams, it is possible to avoid being restricted to a certain customized power battery pack, thereby solving the problem that the existing battery pack side beams cannot be adapted to different vehicle models.

[0091] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
