[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of the present application, and cannot be understood as limiting the embodiments of the present application.

[0030] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one feature. In the description of this application, the meaning of "plurality" is at least two, such as two, three, unless otherwise clearly and specifically defined.

[0032] The longitudinal beam and cross beam are the skeleton of the vehicle and play the role of supporting the vehicle. In order to improve the rigidity and stability of the vehicle, it is necessary to connect the cross beam and longitudinal beam of the vehicle so that the vehicle can be more stable when subjected to external forces and reduce the distortion and deformation of the vehicle.

[0033] At present, the cross beam and longitudinal beam of the vehicle are generally connected by welding. Although welding has the advantage of cost saving, the connection between the cross beam and the longitudinal beam will be subjected to a large impact force during the driving of the vehicle. During the welding process, due to thermal stress and contraction during the cooling process, local stress concentration is likely to occur at the connection. Therefore, under the action of impact force, the connection is prone to breakage and other problems, affecting the safety of vehicle driving.

[0034] The connection assembly 1000 provided in the present application is described in detail below, taking the case where the connection assembly 1000 is applied to a vehicle 2000 , where the vehicle 2000 includes a cross beam 400 and a longitudinal beam 500 .

[0035] See also Figure 1 and Figure 2 The embodiment of the present application provides a connection assembly 1000, which includes a first connection member 100 and a second connection member 200. One of the first connection member 100 and the second connection member 200 is used to connect the longitudinal beam 500 of the vehicle 2000, and the other is used to connect the cross beam 400 of the vehicle 2000. The first connection member 100 is provided with a locking block 10, and the second connection member 200 is provided with a locking groove 20. The locking block 10 and the locking groove 20 are rotatably engaged to connect the first connection member 100 and the second connection member 200.

[0036] For example, the first connector 100 may be used to connect the longitudinal beam 500 of the vehicle 2000 , and the second connector 200 may be used to connect the cross beam 400 of the vehicle 2000 ; or, the second connector 200 may be used to connect the longitudinal beam 500 of the vehicle 2000 , and the first connector 100 may be used to connect the cross beam 400 of the vehicle 2000 .

[0037] In the embodiment of the present application, the first connecting member 100 is used to connect the longitudinal beam 500 of the vehicle 2000, and the second connecting member 200 is used to connect the cross beam 400 of the vehicle 2000.

[0038] See also Figure 3 Optionally, the first connecting member 100 includes a bottom wall 30, a side wall 40 and a hanging ear 50, the side wall 40 is arranged on the bottom wall 30, the hanging ear 50 is arranged on the side wall 40, the hanging ear 50 is hung on the longitudinal beam 500 of the vehicle, and the locking block 10 is arranged on the bottom wall 30.

[0039] Optionally, the first connecting member 100 further includes a reinforcing rib 60 , and two ends of the reinforcing rib 60 are respectively connected to the bottom wall 30 and the side wall 40 .

[0040] See also Figure 4 and Figure 5Optionally, the second connecting member 200 includes a top plate 21 and a side plate 26 , the top plate 21 and the side plate 26 form a U-shaped groove, and the engaging groove 20 is set on the top plate 21 .

[0041] Optionally, the engaging blocks 10 and the engaging slots 20 correspond one to one, and the engaging blocks 10 and the engaging slots 20 each include a plurality, for example, 2, 3, 4, 5, 6, etc.

[0042] Optionally, when the first connector 100 rotates to a preset angle, the engaging block 10 and the engaging slot 20 rotate to engage, and the preset angle is in the interval [5 degrees, 90 degrees]. For example, it can be a preset angle of 30 degrees (°) clockwise, 30 degrees counterclockwise, 40 degrees clockwise, 45 degrees counterclockwise, etc.

[0043] Specifically, the first connector 100 is used to connect the longitudinal beam 500 of the vehicle 1000. The hanging ear 50 of the first connector 100 can be hung on the longitudinal beam 500 of the vehicle 1000, and then the side wall 40 and the longitudinal beam 500 of the vehicle 1000 are fixedly connected by bolts by setting a corresponding number of bolt holes on the side wall 40 and the longitudinal beam 500 of the vehicle 1000, so as to realize that the first connector 100 is connected to the longitudinal beam 500 of the vehicle 1000. The first connector 100 also includes a reinforcing rib 60, and the two ends of the reinforcing rib 60 are respectively connected to the bottom wall 30 and the side wall 40. For example, taking the reinforcing rib 60 as a rod-shaped reinforcing rib 60 as an example, one end of the rod-shaped reinforcing rib 60 can be connected to the bottom wall 30, and the other end is connected to the side wall 40. For another example, taking the reinforcing rib 60 as a block-shaped reinforcing rib 60 as an example, one side of the block-shaped reinforcing rib 60 is connected to the bottom wall 30, and the other side is connected to the side wall 40, so as to improve the structural strength of the first connector 100.

[0044] The second connecting member 200 is used to connect the cross beam 400 of the vehicle 1000. The second connecting member 200 can be connected to the cross beam 400 of the vehicle 1000 by placing a U-shaped groove formed by the top plate 21 and the side plate 26 of the second connecting member 200 on the cross beam 400 of the vehicle 1000, and by providing a corresponding number of bolt holes on the side plate 26 and the cross beam 400 of the vehicle 1000, and fixing the side plate 26 and the cross beam 400 with bolts.

[0045] The bottom wall 30 of the first connecting member 100 is provided with a plurality of (for example, 4) engaging blocks 10, and the top plate 21 of the second connecting member 200 is provided with engaging grooves 20 (i.e., 4 engaging grooves 20) corresponding to the engaging blocks 10, and the 4 engaging blocks 10 correspond to the 4 engaging grooves 20 one by one. When the first connecting member 100 rotates by a preset angle (for example, 30°), the 4 engaging blocks 10 are all driven by the rotation to extend into the 4 engaging grooves 20 to achieve rotational engagement, thereby connecting the first connecting member 100 and the second connecting member 200, and further connecting the cross beam 400 and the longitudinal beam 500 of the vehicle 1000. Please refer to Figure 2 After the first connecting member 100 and the second connecting member 200 are rotated and engaged, it can be as follows Figure 2 Displays the connection status.

[0046] When the cross beam 400 and the longitudinal beam 500 of the vehicle 1000 are connected by connecting the first connecting member 100 and the second connecting member 200, the first connecting member 100 can be connected to the longitudinal beam 500 of the vehicle 1000 first, and then the first connecting member 100 and the second connecting member 200 are rotated and engaged, and finally the second connecting member 200 is connected to the cross beam 400 of the vehicle 1000, so as to complete the connection of the cross beam 400 and the longitudinal beam 500 of the vehicle 1000; or, the first connecting member 100 and the second connecting member 200 can be rotated and engaged first, and then the first connecting member 100 and the second connecting member 200 are connected to the cross beam 400 of the vehicle 1000, respectively. The present application does not impose any restrictions on this and they are not listed here one by one.

[0047] In this way, by setting the first connecting member 100 and the second connecting member 200, the first connecting member 100 is connected to the longitudinal beam 500 of the vehicle 1000, and the second connecting member 200 is connected to the cross beam 400 of the vehicle 1000. The locking block 10 of the first connecting member 100 and the locking groove 20 of the second connecting member 200 (or the locking groove 20 of the first connecting member 100 and the locking block 10 of the second connecting member 200) can be rotatably engaged to connect the first connecting member 100 and the second connecting member 200, thereby realizing the connection between the cross beam 400 and the longitudinal beam 500 of the vehicle 1000. Since the locking block 10 and the locking groove 20 are rotationally locked (that is, the connection between the cross beam 400 and the longitudinal beam 500 of the vehicle 1000 is rotationally locked), during the driving of the vehicle 1000, the impact force received at the connection between the cross beam 400 and the longitudinal beam 500 (that is, the connecting component) can be converted into torque, thereby avoiding the impact force from directly impacting the connecting component at the connection, reducing the probability of the connecting component breaking, horizontal displacement, or deformation under the action of the impact force, thereby improving the stability of the vehicle body and the safety of the vehicle 1000 during driving.

[0048] Please refer to Figure 3 and Figure 6 Optionally, the snap-fit ​​block 10 includes a connecting portion 11 and a snap-fit ​​portion 12, the connecting portion 11 connects the snap-fit ​​portion 12 and the bottom wall 30 of the first connecting member 100, the top plate 21 of the second connecting member 200 is also provided with a mounting groove 22, the mounting groove 22 is connected to the snap-fit ​​groove 20, the shape of the snap-fit ​​block 10 matches the shape of the mounting groove 22, when the snap-fit ​​block 10 is located in the mounting groove 20, the first connecting member 100 can rotate to drive the snap-fit ​​portion 12 to extend into the snap-fit ​​groove 20, so that the snap-fit ​​block 10 and the snap-fit ​​groove 20 are rotationally engaged.

[0049] The shapes of the engaging block 10 and the mounting groove 22 match each other, for example, they may be fan-shaped, rectangular, circular or the like.

[0050] Specifically, the engaging block 10 includes a connecting portion 11 and an engaging portion 12, wherein the connecting portion 11 connects the engaging portion 12 and the bottom wall 30 of the first connecting member 100. The top plate of the second connecting member 200 is provided with a mounting groove 22, the mounting groove 22 is connected with the engaging groove 20, and the shapes of the engaging block 10 and the mounting groove 22 match. That is, when the engaging block 10 and the engaging groove 20 are not rotated and engaged, the engaging block 10 can be placed in the mounting groove 22, and when the first connecting member 100 is rotated by a preset angle (for example, 30° clockwise), the engaging block 10 is also rotated by 30° in the mounting groove 22, and the engaging portion 12 is extended into the engaging groove 20 connected with the mounting groove 22, so that the engaging block 10 and the engaging groove 20 are rotated and engaged.

[0051] See also Figure 4 and Figure 7 In some embodiments, the connecting assembly further includes a locking member 300. When the locking block 10 and the locking groove 20 are rotationally engaged, the locking member 300 is located between the locking block 10 and the groove wall 23 of the locking groove 20 to limit the movement of the locking block 10 in the rotational direction.

[0052] The locking member 300 can be used to restrict the engaging block 10 from being separated from the engaging slot 20 .

[0053] Optionally, the locking member 300 is arranged at the groove bottom 23 of the engaging groove 20, and the locking member 300 includes an elastic member 31 and a supporting block 32. The elastic member 31 is arranged between the groove bottom 23 and the supporting block 32. When the engaging block 10 is located in the engaging groove 20 and is not rotationally engaged with the engaging groove, the supporting block 32 is located between the engaging block 10 and the groove bottom 24 and supports the bottom surface of the engaging block 10. When the engaging block 10 and the engaging groove 20 are rotationally engaged, the supporting block 32 pops out under the action of the elastic member 31 and is located between the engaging block 10 and the groove wall 23 of the engaging groove 20.

[0054] Specifically, the connection assembly 1000 further includes a locking member 300. The locking member 300 includes an elastic member 31 (e.g., a spring, etc.) and a resisting block 32. The elastic member 31 is disposed between the groove bottom 24 and the resisting block 32. When the engaging block 10 is located in the engaging groove 20 and is rotationally engaged with the engaging groove 20 (e.g., when the engaging block 10 is located in the mounting groove 22 and the engaging portion 12 of the engaging block 10 does not extend into the engaging groove 20), the resisting block 32 is located between the engaging block 10 and the groove bottom 24 and resists the bottom surface of the engaging block 10, that is, the engaging block 10 applies a force to the resisting block 32 to apply a force to the elastic member 31, and the elastic member 31 undergoes elastic deformation and contracts under the pressure of the engaging block 10, thereby driving the resisting block 32 to resist the bottom surface of the engaging block 10 between the engaging block 10 and the groove bottom 24.

[0055] When the engaging block 10 and the engaging groove 20 are rotationally engaged (for example, after the engaging block 10 is rotated by a preset angle (such as 30° clockwise), the engaging portion 12 of the engaging block 10 extends into the engaging groove 20), the force applied by the engaging block 10 on the elastic member 31 disappears, the elastic member 31 extends, and the abutting block 32 pops out under the action of the elastic member 31 and is located between the engaging block 10 and the groove wall 23 of the engaging groove 20. When the engaging block 10 moves in the rotational direction due to the impact force exerted on the vehicle 2000 (for example, after the engaging block 10 is rotated 30° clockwise to be rotationally engaged with the engaging groove 20, it rotates counterclockwise under the action of the impact force), the abutting block 32 can abut the engaging block 10, restricting the rotating of the engaging block 10 to disengage from the engaging groove 20, thereby improving the tightness of the connection between the first connecting member 100 and the second connecting member 200.

[0056] See also Figure 5 and Figure 6 Optionally, the groove bottom 24 of the engaging groove 20 is further provided with a receiving groove 25, and the locking member 300 is provided in the receiving groove 25. When the engaging block 10 is located in the engaging groove 20 and is not rotationally engaged with the engaging groove 20, the supporting block 32 is located in the receiving groove 25 and supports the engaging block. When the engaging block 10 and the engaging groove 20 are rotationally engaged, the supporting block 32 pops up under the action of the elastic member 31 and is located between the engaging block 10 and the groove wall 23 of the engaging groove 20.

[0057] Specifically, in order to further improve the limiting effect of the locking member 300 on the movement of the engaging block 10 in the rotational direction, a receiving groove 25 is further provided at the groove bottom 24 of the engaging groove 20, and the locking member 300 is arranged in the receiving groove 25. When the engaging block 10 is located in the engaging groove 20 and is not rotationally engaged with the engaging groove 20 (for example, when the engaging block 10 is located in the mounting groove 22 and the engaging portion of the engaging block 10 does not extend into the engaging groove 20), the supporting block 32 is located in the receiving groove 25 and supports the engaging block 10, that is, the engaging block 10 applies a force to the supporting block 32 to apply a force to the elastic member 31, and the elastic member 31 undergoes elastic deformation and contracts under the pressure of the engaging block 10, so that the supporting block 32 is pressed into the receiving groove 25 and supports the bottom surface of the engaging block 10.

[0058] When the engaging block 10 and the engaging slot 20 are rotationally engaged (for example, after the engaging block 10 is rotated by a preset angle (such as 30° clockwise), the engaging portion of the engaging block 10 extends into the engaging slot 20), the force exerted by the engaging block 10 on the elastic member 31 disappears, the elastic member 31 stretches, the supporting block 32 pops out under the action of the elastic member 31, and is at least partially located between the engaging block 10 and the slot wall 23 of the engaging slot 20, thereby limiting the movement of the engaging block 10 in the rotational direction.

[0059] Please continue reading Figure 7 In some embodiments, the supporting block 32 includes a main body 33 and a boss 34 extending from the main body 33. When the locking block 10 and the locking groove 20 are rotationally engaged, the main body 33 is located between the locking block 10 and the groove wall 23 of the locking groove 20, and the boss 34 resists the bottom surface of the locking block 10.

[0060] Specifically, the abutment block 32 includes a body 33 and a boss 34 extending from the body 33. When the engaging block 10 and the engaging groove 20 are rotated and engaged, the body 33 of the abutment block 32 pops out under the action of the elastic member 31, and the body 33 is located between the engaging block 10 and the groove wall 23 of the engaging groove 20 to limit the engaging block 10 in the rotation direction. The boss 34 extending from the body 33 abuts against the bottom surface of the engaging block 10, and under the action of the engaging block 10, the limiting effect of the abutment block 32 on the engaging block 10 is prevented from being affected by the excessive elongation of the elastic member 31.

[0061] It is understandable that in order to further improve the stability of the locking member 300 , a mounting plate 35 may be provided. The mounting plate 35 is located between the elastic member 31 and the groove bottom 24 and is used to connect the elastic member 31 of the locking member 300 to the groove bottom 24 .

[0062] See also Figure 8 In some embodiments, the locking member 300 is disposed on the bottom wall 30 of the first connecting member 100 and is close to the locking block 10. The locking member 300 includes an elastic member 31 and a supporting block 32. The elastic member 31 is disposed between the bottom wall 30 of the first connecting member 100 and the supporting block 32. The height of the supporting block 32 perpendicular to the bottom wall 30 of the first connecting member 100 is less than the height of the locking block 10 perpendicular to the bottom wall 30 of the first connecting member 100.

[0063] Optionally, when the locking block 10 is located in the locking groove 20 and is not rotationally engaged with the locking groove 20, the supporting block 32 is located between the bottom wall 30 of the first connecting member 100 and the top plate 21 of the second connecting member 200. When the locking block 10 and the locking groove 20 are rotationally engaged, the supporting block 32 extends into the locking groove 20 under the action of the elastic member 31 and is located between the locking block 10 and the groove wall 23 of the locking groove 20.

[0064] Specifically, a locking member 300 can be provided on the bottom wall 30 of the first connector 100 and near the engaging block 10 (for example, adjacent to the engaging block 10). The locking member 300 includes an elastic member 31 and a resisting block 32, wherein the elastic member 31 is provided between the bottom wall 30 of the first connector 100 and the resisting block 32. Since the height of the resisting block 32 perpendicular to the bottom wall 30 of the first connector 100 is less than the height of the bottom wall 30 of the engaging block 10 perpendicular to the first connector 100, when the engaging block 10 is located in the engaging groove 20 and is not rotated and engaged with the engaging groove 20 (for example, when the engaging block 10 is located in the mounting groove 22 and the engaging portion 12 of the engaging block 10 does not extend into the engaging groove 20), the elastic member 31 is subjected to the pressure of the top plate 21, elastically deforms, contracts, and drives the resisting block 32 to resist the bottom wall 30 of the first connector 100 and the top plate 21 of the second connector 200. When the engaging block 10 and the engaging groove 20 are rotationally engaged, the locking member 300 rotates along with the first connecting member 100 (for example, after the engaging block 10 rotates by a preset angle (such as 30° clockwise), the engaging portion of the engaging block 10 extends into the engaging groove 20, and the locking member 300 rotates along with the first connecting member 100 and enters the installation groove 22), the pressure on the elastic member 31 disappears, and the supporting block 32 extends into the engaging groove 20 under the action of the elastic member 31, and is located between the engaging block 10 and the groove wall 23 of the engaging groove 20 to limit the engaging block 10 in the rotation direction.

[0065] In some embodiments, the second connector 200 is used to connect the longitudinal beam 500 of the vehicle 2000, and the first connector 100 is used to connect the cross beam 400 of the vehicle 2000. The principle and implementation method are similar to those described above and will not be described here for brevity.
