[0033] Embodiment 1
[0034] Please refer to the Figures 1 to 6 accompanying drawings. An embodiment of the present utility model provides an armrest bracket. When actually assembling the armrest assembly with the vehicle body, one armrest bracket is provided at each end of an armrest, and the armrest bracket is fixedly connected to the vehicle body.
[0035] The armrest bracket includes: a bracket body 1, the bracket body 1 is a cast aluminum integral molding, the bracket body 1 is provided with a bracket mounting portion 11 and an armrest mounting portion 12, the bottom surface of the bracket mounting portion 11 is provided with a bracket mounting surface, the armrest mounting portion 12 is protruded outward from the middle of the bracket mounting portion 11, and an armrest mounting position 121 is provided on the armrest mounting portion 12. It can be understood that the armrest is a part of the vehicle interior, and the lightweight design of the armrest bracket used to connect and fix the armrest can help reduce the weight of the entire vehicle, thereby improving energy efficiency and endurance. First, in this embodiment, the material used in the traditional bracket is reduced through structural design, and the overall structural layout is optimized. Under the premise of meeting the strength of the armrest bracket, the weight of the armrest bracket is effectively reduced, and the lightweight goal is achieved; further, the bracket body 1 of the cast aluminum one-piece molded part in this embodiment has a low density and good mechanical properties, which can achieve lightweight while ensuring sufficient strength, meeting the needs of modern transportation vehicles to reduce weight and improve energy efficiency. Its one-piece structure reduces the connection and assembly links between components, improves the integrity and stability of the armrest bracket, and can more effectively disperse and transfer stress when subjected to load, and can better resist external shocks and vibrations. Preferably, the bracket body 1 is roughly T-shaped, and the bracket mounting portion 11 is approximately plate-shaped.
[0036] Furthermore, the bracket mounting surface includes a first mounting surface 111 and a second mounting surface 112 extending from the edge of the first mounting surface 111, and the first mounting surface 111 and the second mounting surface 112 form a preset angle. It should be explained that the first mounting surface 111 and the second mounting surface 112 correspond to two mounting surfaces on the body part 2 respectively. Specifically, the preset angle formed by the first mounting surface 111 and the second mounting surface 112 is 135°. Among them, the first mounting surface 111 corresponds to the vertical mounting surface on the body part 2, and the second mounting surface 112 corresponds to the inclined mounting surface on the body part 2. This structure can effectively improve the compressive strength of the armrest bracket in a natural state or under stress. By providing two non-coplanar fulcrums by the first mounting surface 111 and the second mounting surface 112, the armrest bracket can be more tightly and firmly connected to the body part 2, reducing the risk of loosening or falling off due to vibration or impact.
[0037] Preferably, at least one mounting through-hole is provided on each of the first mounting surface 111 and the second mounting surface 112. The mounting through-hole is used to pass through a connecting member so that the bracket mounting portion 11 is firmly connected to the vehicle body member 2. At least two mounting through-holes provide at least two connection points with the vehicle body member 2 at different angles for the bracket mounting portion 11. Multiple connection points can disperse the connection force, improve the connection strength between the armrest bracket and the vehicle body member 2, and reduce the risk of loosening or damage caused by excessive single-point stress. In this embodiment, the bracket mounting portion 11 can fix the armrest bracket to the vehicle body member 2 by bolts and nuts, screws or rivets.
[0038] Specifically, the extension starting point of the armrest mounting portion 12 is located on the back of the junction of the first mounting surface 111 and the second mounting surface 112, so that there is a better supporting effect between the armrest mounting portion 12 and the bracket mounting portion 11, and unnecessary material and space waste are reduced, thereby improving the compactness of the structure, and further ensuring that the armrest bracket has sufficient strength and stability when bearing the forces of the armrest and passengers.
[0039] Further, the bracket mounting portion 11 has a top surface opposite to the bottom surface. The bracket mounting portion 11 has a first end 113 and a second end 114 opposite to the first end 113 in its length direction. A first reinforcing rib 14 is provided on the top surface. The first reinforcing rib 14 extends from the bottom of the armrest mounting portion 12 towards the first end 113. In the armrest bracket, the first reinforcing rib 14 connects the first end 113 of the bracket mounting portion 11 and the armrest mounting portion 12, forming a stable triangular support structure, enhancing the lateral stiffness and torsional resistance of the armrest bracket. When an external force acts on the armrest, the force will be transmitted from the armrest mounting portion 12 to the bracket mounting portion 11. The presence of the first reinforcing rib 14 can more effectively transmit and disperse these stresses, preventing the stresses from concentrating excessively in a local area. Preferably, two first reinforcing ribs 14 are provided, and the two first reinforcing ribs 14 are parallel to each other, and the first reinforcing rib 14 is formed by bending from the long-edge of the top surface.
[0040] Further, a second reinforcing rib 15 is provided on the top surface of the bracket mounting portion 11. The second reinforcing rib 15 extends from the bottom of the armrest mounting portion 12 towards the second end 114. Preferably, the protruding height of the second reinforcing rib 15 gradually decreases from the armrest mounting portion 12 towards the second end 114.
[0041] Further, the end of the armrest mounting portion 12 is inclined towards the direction of the first end 113. The inclined design enables the armrest mounting portion 12 to better disperse these forces to different regions of the bracket mounting portion 11 when receiving the forces of the armrest and passengers, achieving mechanical balance and reducing local stress concentration.
[0042] Further, in order to further achieve the effect of weight reduction, a hollow structure 13 is provided on the armrest mounting portion 12, thereby reducing the weight of the armrest mounting portion 12 and making the overall structural weight of the armrest bracket smaller. Preferably, the hollow structure 13 is provided between the bracket mounting portion 11 and the armrest mounting portion 12.
[0043] Preferably, the armrest mounting position 121 is a through hole formed in the armrest mounting portion 12, and the armrest can be fixed to the armrest mounting position 121 by bolts, nuts, screws or rivets.
[0044] Embodiment 2
[0045] An embodiment of the present invention provides an armrest assembly, which includes two armrest brackets and an armrest. The two bracket connection ends of the armrest are respectively connected to one of the armrest brackets; the armrest bracket is the armrest bracket as described above.
[0046] Different from the prior art, this embodiment abandons the sheet metal connection structure provided between the two armrest mounting areas, and uses two mutually independent armrest brackets with armrest mounting positions 121 to mount an armrest, effectively reducing the mass of a single armrest bracket and the assembled armrest assembly, achieving the goal of weight reduction. Moreover, in a vehicle, only one armrest bracket needs to be developed to adapt to armrests of different sizes. Compared with traditional multi-model brackets, a single-model armrest bracket has higher cost-effectiveness in the production process and reduces the development cost. It is worth mentioning that since this embodiment reduces the sheet metal connection structure between the two armrest mounting areas on the traditional bracket, there is no connection structure between the two armrest brackets in an armrest assembly. While a single armrest bracket is small in size, compact in structure and light in weight, which helps to reduce weight and cost and improve the competitiveness of the vehicle product, it can also vacate the space position between the two armrest brackets to appropriately arrange the installation points of other parts according to requirements, making the design more flexible and free.
[0047] Embodiment 3
[0048] Please refer to Figure 5 and Figure 6 , an embodiment of the present invention provides a vehicle, which includes the above-mentioned armrest assembly and a body part 2, and the armrest assembly is connected to the body part 2.
[0049] Preferably, an installation boss 21 is provided on the vehicle body part 2, and the bracket installation part 11 is connected to the installation boss 21. Specifically, a first boss surface 211 corresponding to the first installation surface 111 and a second boss surface 212 corresponding to the second installation surface 112 are provided on the installation boss 21. It can be understood that during the design stage of the vehicle body part 2, the height and position of the installation boss 21 can be adjusted according to the layout requirements of the armrest bracket, so as to ensure that the position input requirements of the armrest installation part 12 can be met without changing the structure of the armrest bracket. It should be explained that installation holes are preset on the installation boss 21. During the assembly stage, the installation through holes opened on the bracket installation surface need to be aligned with the installation holes and then connected by bolts and nuts. Preferably, multiple groups of installation holes with different positions can be provided on the installation boss 21 to adapt to the change of the installation position of the armrest assembly on the installation boss 21.
[0050] The armrest bracket, armrest assembly and vehicle of this embodiment realize the lightweight of the armrest bracket by simplifying the structure of the armrest bracket, reduce the mass after the assembly of the armrest and the armrest bracket, and effectively improve the degree of lightweight.
[0051] The above only uses the embodiment to further illustrate the technical content of the present invention to make it easier for readers to understand, but it does not mean that the implementation manner of the present invention is limited to this. Any technical extension or re-creation made according to the present invention is protected by the present invention. The protection scope of the present invention is subject to the claims.
