Description

Technical Field

[0001] This application relates to the field of vehicle parts technology, and in particular to a handrail mounting bracket and a vehicle. Background Technology

[0002] As a key load-bearing component connecting the armrest assembly to the vehicle body structure, the structural design and mechanical performance of the automotive interior armrest mounting bracket directly determine the safety and reliability of the occupant support system. The armrest mounting bracket achieves a rigid connection to the B-pillar or other body structures through a precision positioning structure. Under conditions such as passengers actively gripping the armrest during entry and exit, severe bumps during vehicle movement, or collisions, the bracket must efficiently distribute the dynamic impact load borne by the armrest surface to the vehicle body structure through a multi-path transmission mechanism to prevent armrest dislocation and subsequent occupant injury.

[0003] However, the handrail mounting brackets commonly used in existing technologies have significant structural defects, exhibiting weak structural strength and rigidity. When passengers use the handrails to board the vehicle, the insufficient strength of the mounting brackets can easily lead to safety accidents. More seriously, in the event of a side collision, the weld points connecting the brackets to the vehicle body are prone to tearing and failure, increasing the probability of the handrail assembly dislodging and directly threatening the safety of the occupants' heads. Utility Model Content

[0004] This application provides a handrail mounting bracket and a vehicle, which improves the structural strength and installation stability of the handrail mounting bracket, thereby at least partially solving the above-mentioned technical problems.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0032] The existing armrest mounting brackets in automobiles have relatively weak structural strength and rigidity. When passengers use the armrests to get into the car, the insufficient strength of the armrest mounting brackets can easily lead to safety accidents. In addition, many armrest mounting brackets adopt complex structural designs to improve structural strength, which requires multiple stamping processes and increases production costs. Finally, lightweighting is one of the core competitive advantages of automakers. Although the armrest mounting brackets are small, their cumulative effect on the weight of the entire vehicle is significant. Current technology makes it difficult to reduce the weight of the armrest mounting brackets while ensuring strength.

[0033] The inventor proposed a handrail mounting bracket and vehicle, which, while ensuring structural strength and connection strength with the vehicle body, has the advantages of compact structure and light weight, and can be processed in one piece, reducing production steps and manufacturing costs.

[0034] According to a first aspect of this application, a handrail mounting bracket is provided; please refer to [reference needed]. Figures 1 to 5 , Figure 1 , Figure 2 and Figure 3 These are schematic diagrams of the overall structure of the handrail mounting bracket provided in the embodiments of this application at three different angles; Figure 4 A schematic diagram of the installation position of the armrest mounting bracket on the vehicle body structure provided in the embodiments of this application; Figure 5 For this application Figure 4 The partial cross-sectional view at point B in the diagram shows the connection structure between the armrest mounting bracket and the vehicle body structure.

[0035] An armrest mounting bracket is provided for mounting armrests to a vehicle body structure 3. The armrest mounting bracket includes a mounting structure 1 and a connecting structure 2. The mounting structure 1 is used to connect to the armrest. The connecting structures 2 are disposed on opposite sides of the mounting structure 1, and each connecting structure 2 includes a first connecting portion 21 and a second connecting portion 22 arranged at an angle. The first connecting portion 21 and the second connecting portion 22 are respectively connected to two adjacent sides of the vehicle body structure 3. The armrest can be conveniently and quickly installed to the vehicle body structure 3 through the armrest mounting bracket. In addition, the connecting structure 2, including the first connecting portion 21 and the second connecting portion 22, realizes multi-faceted connection with the vehicle body structure 3, enhances the connection strength between the armrest mounting bracket and the vehicle body structure 3, and thus ensures the stability of the armrest installation.

[0036] In some embodiments, refer to Figure 5 The first connecting part 21 and the second connecting part 22 form a first included angle A; the first included angle A is greater than or equal to 105° and less than 180°, and the first connecting part 21 and the second connecting part 22 constitute an obtuse angle folded structure. The first included angle A is set at a large angle, which facilitates the processing and forming of the connecting structure 2, and the first connecting part 21 and the second connecting part 22 can form a cross structure, thereby improving the structural rigidity of the connecting structure 2.

[0037] In some embodiments, the vehicle body structure 3 is a B-pillar inner panel; both the first connecting portion 21 and the second connecting portion 22 are welded to the B-pillar inner panel. It is understood that the B-pillar inner panel has adjacent first and second surfaces, the first connecting portion 21 is welded to the first surface of the B-pillar inner panel, and the second connecting portion 22 is welded to the second surface of the B-pillar inner panel.

[0038] It should be noted that when the included angle between the first and second surfaces of the vehicle body structure 3 is 180°, the first connecting part 21 and the second connecting part 22 are also coplanar, and the first included angle A is 180°. Therefore, the first included angle A can be any value within the range of 105°, 120°, 150°, and 180° or any combination of both.

[0039] In some embodiments, refer to Figures 1 to 3 The mounting structure 1 is approximately U-shaped, comprising two spaced-apart vertical sections 11 and a horizontal section 12 connecting the two vertical sections. The ends of the vertical sections 11 furthest from the horizontal section 12 are connected to the first connecting section 21. The horizontal section 12 is connected to the handrail by bolts. It is understood that the U-shaped design of the mounting structure 1 creates a gap between the handrail connection point and the vehicle body structure 3, providing operational space for the installation and disassembly of bolts or other connecting structures. Furthermore, compared to a conventional plate-like structure, the U-shaped structure improves the structural rigidity of the mounting structure 1.

[0040] Specifically, both the vertical part 11 and the horizontal part 12 are plate bodies. The handrail is located on the side of the horizontal part 12 away from the connecting structure 2. After the bolt passes through the horizontal part 12 and the handrail, it is fixed by nuts.

[0041] Specifically, the joints between the vertical portion 11 and the horizontal portion 12, the joint between the vertical portion 11 and the first connecting portion 21, and the joint between the first connecting portion 21 and the second connecting portion 22 are all rounded. Rounding the corners disperses stress through a smooth transition, avoiding stress concentration at right angles or sharp corners, significantly reducing stress peaks, and also preventing scratches caused by occupant contact during collisions or sudden braking. The rounded corner design also reduces wear on production molds, facilitating stamping.

[0042] In some embodiments, at least one free end side of the transverse portion 12 is arc-shaped. It is understood that the arc-shaped design can enhance the end section modulus and strengthen the structure.

[0043] Specifically, one free end side of the horizontal section 12 is set to an arc shape, while the other opposite free end side is set to a straight shape. The arc-shaped free end side is closer to the occupant to further reduce the risk of impact injury to the human body. In other scenarios, both free end sides of the horizontal section 12 can also be set to arc shapes to enhance the end bending section modulus of the horizontal section 12.

[0044] In some embodiments, the mounting structure 1 further includes a first reinforcing part 13; a gap is provided between the first reinforcing part 13 and the vehicle body structure 3, and the first reinforcing part 13 is connected to two vertical parts 11 and a horizontal part 12 respectively. By providing the first reinforcing part 13, the structural strength of the mounting structure 1 is further improved, and the gap between the first reinforcing part 13 and the vehicle body structure 3 can improve the structural strength while avoiding a significant increase in structural weight.

[0045] In some embodiments, the first reinforcing part 13 is formed by bending the free end side of the horizontal part 12 toward the vehicle body structure 3, and at least one first reinforcing part 13 is provided.

[0046] It should be noted that in some scenarios, the first reinforcing part 13 is provided on the free end side of the horizontal part 12 near the occupant, while the other free end sides are not provided with the first reinforcing part 13. When installing or removing the armrest, the operator can work from the side without the first reinforcing part 13, obtaining a larger working access space. Specifically, when the free end side of the horizontal part 12 near the occupant is set to an arc shape, the first reinforcing part 13 extends along the arc-shaped free end side of the horizontal part 12 towards the vehicle body structure 3, so that the first reinforcing part 13 has the same trend as the edge of the horizontal part 12. In other scenarios, both free end sides of the horizontal part 12 are bent towards the vehicle body structure 3, forming two first reinforcing parts 13, so that the mounting structure 1 obtains greater structural strength.

[0047] In some embodiments, a through threaded hole is provided in the middle of the horizontal part 12, and the bolt is inserted into the threaded hole and threadedly engaged with it to increase the fastening of the bolt connection.

[0048] In some embodiments, the upright portion 11 includes a second reinforcing portion 14, which is connected to the free end of the upright portion 11 and to the first reinforcing portion. Specifically, at least one free end side of the upright portion 11 bends and extends toward another upright portion 11 to form the second reinforcing portion 14. By providing the second reinforcing portion 14, the structural strength of the mounting structure 1 is further improved.

[0049] At least one free end side of the upright portion 11 bends and extends toward the other upright portion 11. Specifically, at least one free end side of the upright portion 11 bends and extends toward the other upright portion 11 along the edge of the reinforcing portion 14 to form a second reinforcing portion 14, so as to ensure smooth force transmission between the first reinforcing portion 13 and the second reinforcing portion 14 and avoid local stress concentration caused by abrupt changes in direction.

[0050] It should be noted that in some scenarios, the second reinforcing part 14 is located on the free end side of the upright part 11 near the occupant, and the first reinforcing part 13 is also located on the free end side of the upright part 11 near the occupant, with the second reinforcing part 14 connected to the first reinforcing part 13. Similarly, when installing or removing the handrail, the operator can work from the side without the second reinforcing part 14 and the first reinforcing part 13, thus obtaining a larger working access space.

[0051] In other scenarios, the two free ends of the upright portion 11 are bent toward the other upright portion 11 to form two second reinforcing portions 14, thereby giving the mounting structure 1 greater structural strength.

[0052] Specifically, the second reinforcing parts 14 on the same side of the two upright parts 11 are spaced apart from each other to reduce the weight impact of the second reinforcing parts 14 on the overall structure.

[0053] In some embodiments, the second connecting portion 22 includes a third reinforcing portion 23, which is connected to the side of the second connecting portion 22 that is close to each other, and is also connected to the second reinforcing portion 14. Specifically, the side of the second connecting portion 22 that is close to each other is bent and extended away from the vehicle body structure 3 to form the third reinforcing portion 23. By providing the third reinforcing portion 23, the structural strength of the connecting structure 2 is improved.

[0054] The side of the second connecting part 22 that is close to each other bends and extends away from the vehicle body structure 3. Specifically, the side of the second connecting part 22 that is close to each other bends and extends along the edge direction of the second reinforcing part 14. That is, the extension direction of the third reinforcing part 23 is the same as that of the second reinforcing part 14, thereby ensuring smooth force transmission and avoiding local stress concentration caused by abrupt change in direction.

[0055] In some embodiments, the mounting structure 1 and the connecting structure 2 are integrally stamped from sheet metal. Specifically, both the mounting structure 1 and the connecting structure 2 are made of hard metal materials, such as stainless steel or other high-strength metal materials.

[0056] In the handrail mounting bracket of this application embodiment, the connection strength between the handrail mounting bracket and the vehicle body structure 3 is improved by multi-face welding of the first connecting part 21 and the second connecting part 22; at the same time, by setting the first reinforcing part 13, the second reinforcing part 14 and the third reinforcing part 23, the structural strength of the handrail mounting bracket can be effectively improved; the simultaneous improvement of connection strength and structural strength can reduce the probability of safety accidents when passengers use force to get on and off the vehicle, when the vehicle is bumpy or when a collision occurs.

[0057] According to a second aspect of this application, a vehicle is provided, referring to... Figures 1 to 5The vehicle includes a body structure 3, an armrest, and the aforementioned armrest mounting bracket. The armrest is mounted to the body structure 3 via the armrest mounting bracket, which includes a mounting structure 1 and a connecting structure 2. The mounting structure 1 is used to connect with the armrest. The connecting structures 2 are located on opposite sides of the mounting structure 1, and each connecting structure 2 includes a first connecting portion 21 and a second connecting portion 22 arranged at an angle. The first connecting portion 21 and the second connecting portion 22 are respectively connected to two adjacent sides of the body structure 3. The armrest can be easily and quickly installed to the body structure 3 via the armrest mounting bracket. In addition, the connecting structure 2, including the first connecting portion 21 and the second connecting portion 22, achieves multi-faceted connection with the body structure 3, enhances the connection strength between the armrest mounting bracket and the body structure 3, and thus ensures the stability of the armrest installation.

[0058] In some embodiments, refer to Figure 4 Two handrail mounting brackets are spaced apart, and the two handrail mounting brackets are connected to the two ends of the handrail by bolts.

[0059] In some embodiments, the vehicle body structure 3 is a metal structural component of the vehicle body that is weldable. In a typical embodiment, it is selected from the inner panel of the B-pillar, but it does not exclude homogeneous structures such as door sill plates, seat crossbeams, or roof longitudinal beams.
