[0001] The embodiments of the present application relate to the field of vehicle technology, and in particular to a reinforcement bracket and a vehicle. Background Art
[0002] As people's requirements for automobile driving performance become higher and higher, their requirements for automobile driving performance on ordinary road conditions and washboard road conditions are also increasing. Strengthening the structural performance of the subframe can reduce the impact of road conditions on the comfort inside the vehicle, and can effectively improve the driving performance of the entire vehicle and improve driving comfort.
[0003] In the prior art, in order to enhance the structural performance of the subframe, a reinforcing bracket is connected between the bushing and the longitudinal beam of some subframes, and the load borne by the subframe is shared by the reinforcing bracket. However, in the prior art, the connection accuracy between the reinforcing bracket and the subframe is poor, which is not conducive to the reinforcing bracket to stably share the load borne by the subframe. Summary of the invention

The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.
[0045] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to the changes in the orientation of the components in the drawings.
[0046] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
[0047] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.
[0048] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.
[0049] The embodiment of the present application provides a reinforcing bracket 1, including a bracket body 104. The bracket body 104 is provided with a first connecting structure 101, a second connecting structure 102 and a limiting structure 103. The first connecting structure 101 and the limiting structure 103 are both arranged at the first end of the bracket body 104, the first connecting structure 101 is suitable for connecting with the subframe 3 of the vehicle, and the limiting structure 103 is suitable for limiting the position of the subframe 3. The second connecting structure 102 is arranged at the second end of the bracket body 104, and is suitable for connecting with the longitudinal beam 5 of the vehicle.
[0050] The first connection structure 101 of the reinforcing bracket 1 provided in the embodiment of the present application can be used to connect to the subframe 3, the second connection structure 102 can be connected to the longitudinal beam 5 of the vehicle, and the bracket body 104 can share the load borne by the subframe 3, thereby strengthening the structural performance of the subframe 3, thereby reducing the impact of road spectrum on the comfort inside the vehicle, and effectively improving the performance of the entire vehicle and improving driving comfort.
[0051] On the other hand, the energy of the vehicle collision can be transmitted along the bracket body 104 of the reinforcing bracket 1. Therefore, the setting of the reinforcing bracket 1 produces a new force transmission path. The new force transmission path can effectively improve the collision performance of the vehicle and further decompose and absorb the energy of the vehicle collision, thereby reducing the pressure of the collision energy on the subframe 3.
[0052] In addition, the reinforcing bracket 1 of the present embodiment further includes a limiting structure 103. The limiting structure 103 can cooperate with the sub-frame 3 to limit the connection, thereby improving the connection accuracy and connection strength between the reinforcing bracket 1 and the sub-frame 3, and can effectively improve the structural strength of the reinforcing bracket 1. At the same time, when the operator connects the reinforcing bracket 1 to the sub-frame 3, the limiting structure 103 can be used to pre-position the reinforcing bracket 1 on the sub-frame 3, which can facilitate the operator to connect the reinforcing bracket 1 to the sub-frame 3 and avoid deviation in the installation position of the reinforcing bracket 1.
[0053] Therefore, the connection accuracy and connection strength between the reinforcing bracket 1 and the subframe 3 of this embodiment are high, which can effectively improve the structural strength of the reinforcing bracket 1 and reduce the pressure on the subframe 3 caused by the collision energy, thereby improving the performance of the entire vehicle and improving driving comfort.
[0054] The subframe 3 may be selected as a rear subframe, in which case the longitudinal beam 5 is preferably a rear longitudinal beam. As a convertible embodiment, the subframe 3 may also be selected as a front subframe, in which case the longitudinal beam 5 is preferably a front longitudinal beam. Preferably, in this embodiment, the first connecting structure 101 is connected to the bushing 4 of the subframe 3, and the limiting structure 103 is limitedly matched with the bushing 4 of the subframe 3. The subframe 3 is connected to the rear integral aluminum casting of the vehicle body 2. The reinforcing bracket 1 is preferably a high-strength hot-formed sheet metal bracket. As a convertible embodiment, the reinforcing bracket 1 may also be selected as an aluminum alloy extruded profile or a vacuum die casting.
[0055] Further, in some embodiments of the present application, the first connection structure 101, the second connection structure 102, the limiting structure 103 and the bracket body 104 are integrally formed, which can improve the integration of the reinforcing bracket 1 and help reduce the number of parts of the vehicle. As a convertible embodiment, the first connection structure 101, the second connection structure 102, the limiting structure 103 and the bracket body 104 are welded to each other.
[0056] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more.
[0057] Furthermore, in some embodiments of the present application, the limiting structure 103 includes a limiting flange 1031 suitable for being inserted into the bushing 4 of the sub-frame 3 .
[0058] The limiting flange 1031 can cooperate with the bushing 4 to not only improve the connection accuracy between the reinforcing bracket 1 and the subframe 3, but also improve the connection strength between the reinforcing bracket 1 and the subframe 3, and also help to improve the structural strength of the reinforcing bracket 1.
[0059] For example, refer to Figure 1 , Figure 2 and Figure 5 The number of the limiting flanges 1031 is multiple, and the multiple limiting flanges 1031 are arranged at intervals. The outer wall of the limiting flange 1031 is used to abut against the inner wall of the bushing 4. The length of the limiting flange 1031 is L1, 5mm≤L1≤10mm.
[0060] As a convertible implementation, the limiting structure 103 may also optionally include a limiting protrusion formed on the first bending portion 1011 , and the limiting protrusion can be limitedly matched with the groove on the bushing 4 .
[0061] Further, in some embodiments of the present application, the first connection structure 101 includes a first bent portion 1011 and a first bolt hole 1012 formed on the first bent portion 1011. The first bent portion 1011 is suitable for being connected to the sub-frame 3 through the first bolt hole 1012.
[0062] The second connection structure 102 includes a second bent portion 1021 and a second bolt hole 1022 formed on the second bent portion 1021. The second bent portion 1021 is suitable for being connected to the longitudinal beam 5 through the second bolt hole 1022.
[0063] Furthermore, in some embodiments of the present application, a bracket groove 1013 is provided on the first bending portion 1011. The bracket groove 1013 is located on a side surface of the first bending portion 1011 away from the limiting structure 103, and the first bolt hole 1012 is provided at the bottom of the bracket groove 1013.
[0064] When the assembly bolt passes through the first bolt hole 1012 and connects the first bent portion 1011 and the sub-frame 3, the bracket groove 1013 can wrap and strengthen the head of the assembly bolt to improve the connection performance between the reinforcement bracket 1 and the sub-frame 3. At the same time, the bracket groove 1013 can also be used to improve the structural strength of the reinforcement bracket 1. Preferably, the cross section of the bracket groove 1013 along the length direction of the first connection structure 101 is U-shaped.
[0065] Furthermore, in some embodiments of the present application, the first connection structure 101 and the second connection structure 102 are respectively arranged at an angle to the bracket body 104, and the first connection structure 101 and the second connection structure 102 extend in opposite directions relative to the bracket body 104, forming a Z-shaped structure.
[0066] Since the subframe 3 is mainly subjected to energy fluctuations in the vertical direction, when the first connection structure 101 of the reinforcing bracket 1 is connected to the subframe 3 and the second connection structure 102 is connected to the longitudinal beam 5, the bracket body 104 can extend in the vertical direction as a whole, and can more easily realize energy transfer in the vertical direction, which is helpful to strengthen the structural performance of the reinforcing bracket 1 and the subframe 3.
[0067] For example, refer to Figure 4 When the bracket body 104 extends in the vertical direction, the bracket body 104, the first connection structure 101 and the bushing 4 of the subframe 3 can together form a reinforcement cavity. The reinforcement cavity can greatly improve the structural strength of the subframe 3, thereby effectively improving the performance and driving comfort of the vehicle.
[0068] As a convertible implementation, the bracket body 104 is smoothly connected between the first connection structure 101 and the second connection structure 102 .
[0069] Furthermore, in some embodiments of the present application, one end of the bracket body 104 is provided with a bending section 105 that is bent toward the first connection structure 101. The bracket body 104 is smoothly connected to the first connection structure 101 through the bending section 105.
[0070] The bending section 105 can effectively increase the pressing force of the first bending portion 1011 on the sub-frame 3, and can effectively increase the size of the reinforcement cavity, and further improve the structural strength of the sub-frame 3. In addition, the bending section 105 and the bracket groove 1013 can form a continuous concave-convex structure, which can further decompose and absorb the energy generated by the collision, and reduce the pressure of the collision energy on the sub-frame 3.
[0071] Further, in some embodiments of the present application, the reinforcing bracket 1 further includes a reinforcing flange 106 provided along the edge of the bracket body 104 and the first connecting structure 101. The reinforcing flange 106 is folded in a direction away from the limiting structure 103. The reinforcing flange 106 can enhance the structural strength of the reinforcing bracket 1. Preferably, the height of the reinforcing flange 106 is h1, 3mm≤h1≤5mm.
[0072] The reinforcing bracket 1 further includes a reinforcing rib 107 connected between the bracket body 104 and the second connecting structure 102. The reinforcing rib 107 can effectively improve the connection performance between the subframe 3 and the longitudinal beam 5. Preferably, the height of the reinforcing rib 107 is h2, 8mm≤h2≤15mm.
[0073] According to an embodiment of the present utility model, on the other hand, a vehicle is also provided, such as Figure 6As shown, the vehicle includes a vehicle body 2, a subframe 3, a longitudinal beam 5 and a reinforcing bracket 1. The subframe 3 and the longitudinal beam 5 are respectively connected to the vehicle body 2. The reinforcing bracket 1 is connected to the subframe 3 through a first connecting structure 101, connected to the longitudinal beam 5 through a second connecting structure 102, and the limiting structure 103 is limitedly matched with the subframe 3.
[0074] The vehicle of the second aspect of the utility model includes or uses the reinforcing bracket 1 of the first aspect of the utility model, and thus has the beneficial effects of the reinforcing bracket 1, namely: the connection accuracy and connection strength between the reinforcing bracket 1 and the subframe 3 are high, which can effectively improve the structural strength of the reinforcing bracket 1 and reduce the pressure on the subframe 3 caused by collision energy, thereby improving the performance of the entire vehicle and improving driving comfort.

[0078] Further, in some embodiments of the present application, a third bolt hole 201 is formed at the connection between the vehicle body 2 and the subframe 3. The vehicle further includes an assembly bolt 7 and a sleeve 6. The sleeve 6 is disposed in the third bolt hole 201, and the assembly bolt 7 is sequentially passed through the first connection structure 101 and the bushing 4 of the subframe 3 and connected to the third bolt hole 201 through the sleeve 6.
[0079] The sleeve 6 can strengthen the structure at the third bolt hole 201 of the vehicle body 2 and improve the connection strength between the reinforcing bracket 1, the bushing 4 and the vehicle body 2. Preferably, a limiting convex eave is formed on the outer periphery of the top of the sleeve 6, and a limiting groove is also provided on the vehicle body 2.

[0081] It should be noted that in the embodiments of the present application, the specific form of the reinforcement structure is not limited, and it can be set according to the load that the connection between the vehicle body 2 and the subframe 3 needs to bear. Exemplarily, in some embodiments of the present application, the reinforcement structure includes a first reinforcement section 205, a second reinforcement section 206, and a third reinforcement section 207. Among them, the first reinforcement section 205 is arranged around the outside of the hole wall of the third bolt hole 201, and a first reinforcement cavity arranged around the outside of the hole wall of the third bolt hole 201 is formed in the first reinforcement section 205. There are at least two first reinforcement cavities, which are arranged at intervals in the vertical direction, and can be used to enhance the structural strength of the connection between the vehicle body 2 and the subframe 3.
[0082] In some embodiments of the present application, reference Figure 4 The first reinforcement section 205 includes two reinforcement chambers spaced apart in the vertical direction. Figure 4 The cross section is in the shape of a Japanese character. Figure 4 The cross section in FIG. 1 extends along the length direction of the vehicle and passes through the axis of the mounting bolt 7 .

Along the length direction of the vehicle body 2, the width of the first segment 2051 is smaller than the width of the second segment 2052.
[0084] The second reinforcement section 206 is disposed below the first reinforcement section 205 . In some embodiments of the present application, a second reinforcement cavity extending along the width direction of the vehicle body 2 is disposed in the second reinforcement section 206 .
[0085] In some embodiments of the present application, reference Figure 4 The number of the second reinforcement cavity is one, and the second reinforcement section 206 is along Figure 4 The cross section is a square shape, which can reduce the material used in the vehicle body 2 and reduce the weight of the vehicle body 2.

In some embodiments of the present application, a third reinforcement cavity extending along the width direction of the vehicle body 2 is formed in the third reinforcement section 207, and the number of the third reinforcement cavity is greater than the second reinforcement cavity. The third reinforcement section 207 is supported below the first reinforcement section 205 and the second reinforcement section 206 to enhance the structural strength of the vehicle body 2.

[0088] On this basis, refer to Figure 8 In some embodiments of the present application, a cavity extending along the length direction of the longitudinal beam 5 is formed in the longitudinal beam 5. A reinforcing plate 502 is arranged in the cavity. A fourth bolt hole 5021 is formed on the reinforcing plate 502, and the reinforcing plate 502 is connected to the longitudinal beam 5 and the reinforcing bracket 1 through the fourth bolt hole 5021.
[0089] The reinforcing plate 502 can be used to improve the structural strength of the longitudinal beam 5, and can also improve the connection strength between the longitudinal beam 5 and the reinforcing bracket 1, and further improve the connection strength between the longitudinal beam 5 and the vehicle body, so as to improve the structural strength of the entire subframe 3 and improve the frame structure performance and driving performance of the vehicle.

Preferably, in some embodiments, the end surface of the longitudinal beam 5 is closed, which can further improve the strength of the longitudinal beam 5.
[0091] A limiting sleeve 202 is formed at the connection between the vehicle body 2 and the longitudinal beam 5.
