Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a seat support and seat assembly. Background Technology

[0002] With the continuous improvement of people's living standards, the demand for energy-saving, environmentally friendly, lightweight, diverse, complementary, and aesthetically pleasing transportation tools is becoming increasingly urgent. Electricity, as an environmentally friendly, clean, and highly efficient energy source, is widely used in production and daily life. Using electricity to drive the upgrading of transportation tools, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment is one of the important research topics in countries around the world. Electric vehicles, as a green sunrise industry, have been developing in China for ten years. In terms of electric bicycles, by the end of 2010, China had 120 million electric bicycles, and this number is growing at a rate of 30% annually. From an energy consumption perspective, electric bicycles consume only one-eighth the energy of motorcycles and one-twelfth the energy of cars. In terms of space occupied, an electric bicycle occupies only one-twentieth the space of a typical private car, making it a very effective energy-saving transportation tool. From a development trend perspective, the market prospects for the electric bicycle industry remain promising. In particular, as an energy-saving, environmentally friendly, convenient, and relatively low-cost medium- and short-distance transportation tool, electric bicycles are very popular in second- and third-tier cities and rural areas. With the improvement of the industrial development environment, the acceleration of rural road construction, and the increase in residents' income levels, the market space will further expand. Electric bicycles, with their advantages of low price, convenience, and environmental friendliness, are favored by low- and middle-income urban residents.

[0003] The seat of an electric vehicle is supported by a seat support frame. Traditional seat supports are a one-piece structure, meaning that the two ends of the connecting rod are welded to the support rods on both sides and cannot be separated, resulting in a large size and increased logistics and transportation costs.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Based on the shortcomings of existing technologies, the following section combines specific examples. Figure 1-6 The structure of the seat cushion bracket of this utility model is described in detail.

[0030] like Figure 1 The diagram shown is a structural schematic of a preferred embodiment of the seat cushion bracket of this utility model. The seat cushion bracket includes a first support rod 1, a second support rod 2, and a connecting rod 3. The first support rod 1 and the second support rod 2 are both L-shaped and symmetrically arranged. The connecting rod 3 is installed between the first support rod 1 and the second support rod 2, and both ends of the connecting rod 3 are detachably connected to the first support rod 1 and the second support rod 2. That is, the first support rod 1, the connecting rod 3, and the second support rod 2 form an H-shaped structure.

[0031] In this embodiment, the end of the first support rod 1 furthest from the connecting rod 3 is designed as a straight line, and the end of the second support rod 2 furthest from the connecting rod 3 is also designed as a straight line. Figure 2 and Figure 3 As shown.

[0032] The connecting rod 3 of this utility model can be assembled with the first support rod 1 and the second support rod 2, or it can be disassembled from the first support rod 1 and the second support rod. The disassembled connecting rod 3, the first support rod 1 and the second support rod 2 can reduce the packaging volume during transportation, thereby reducing transportation costs.

[0033] Specifically, both ends of the connecting rod 3 are detachably connected to the first support rod 1 and the second support rod 2 by screws.

[0034] like Figure 2 and Figure 3 As shown, the screws in this embodiment include a first screw 4 and a second screw 5. The first support rod 1 is provided with a first countersunk hole 11, and the second support rod 2 is provided with a second countersunk hole 21. The first screw 4 passes through the first countersunk hole 11 on the first support rod 1 and is threaded to the end of the connecting rod 3. The second screw 5 passes through the second countersunk hole 21 on the second support rod 2 and is threaded to the end of the connecting rod 3.

[0035] The first countersunk hole 11 and the second countersunk hole 21 can strengthen the fixation of the first screw 4 and the second screw 5 on the first support rod 1 and the second support rod 2, thereby strengthening the connection strength between the two ends of the connecting rod 3 and the first support rod 1 and the second support rod 2. When the screw is tighter, the countersunk head of the screw and the first countersunk hole 11 and the second countersunk hole 21 fit more precisely, thereby enhancing the stability.

[0036] More specifically, such as Figure 4 and Figure 5 As shown, the connecting rod 3 is a hollow cylindrical tube, and threaded sleeves 6 are provided inside both ends. The length of the threaded sleeves 6 is not less than 5cm. The threaded sleeves 6 are fixed inside the hollow cylindrical tube. The threaded sleeves 6 and the ends of the hollow cylindrical tube form a stepped structure. The threaded sleeves 6 at both ends of the connecting rod 3 can be threadedly connected with the first screw 4 and the second screw 5, thereby strengthening the connection strength between the connecting rod 3 and the first support rod 1 and the second support rod 2. This connection strength can achieve the same degree of firmness as welding.

[0037] See also Figure 5 As shown, the end side wall of the connecting rod 3 is provided with a semi-circular slot that matches the arc-shaped outer wall of the first support rod 1 and the arc-shaped outer wall of the second support rod 2.

[0038] This embodiment includes two semi-circular latches. The curvature of the two semi-circular latches is consistent with the curvature of the outer wall of the first support rod 1 and the outer wall of the second support rod 2. In this way, the end of the connecting rod 3 can fit well against the outer wall of the first support rod 1 and the outer wall of the second support rod 2, further strengthening the connection strength between the connecting rod 3 and the first support rod 1 and the second support rod 2, thereby making the seat cushion support more stable and without any wobbling.

[0039] In this embodiment, the semi-circular notch on the connecting rod 3 is cut using a laser process.

[0040] Unlike the above-described implementation method, as follows: Figure 6 As shown, in this embodiment, the end of the first support rod 1 away from the connecting rod 3 is set to an arc-shaped bend, and the end of the second support rod 2 away from the connecting rod 3 is also set to an arc-shaped bend.

[0041] When both the first support rod 1 and the second support rod 2 are set to be curved and bent, the end of the first support rod 1 is set as a plug-in end, and the end of the second support rod 2 is set as a plug-in end that is adapted to the plug-in end.

[0042] The radius of the first support rod 1 is the same as the radius of the second support plate. Thus, when the insertion end of the first support rod 1 is inserted into the insertion end of the second support rod 2, the arc-shaped bend of the first support rod 1 and the arc-shaped bend of the second support rod 2 can form a U-shaped handrail.

[0043] Unlike the above-described implementation method, as follows: Figure 7 As shown, it also includes a U-shaped handrail 7, the end of which is detachably connected to both the first support rod 1 and the second support rod 2.

[0044] The U-shaped handrail 7, the first support rod 1, the second support rod 2, and the connecting rod are set separately to further reduce the transport volume and thus reduce the transport cost.

[0045] In this embodiment, both the first support rod 1 and the second support rod 2 have plug-in ends, and the two ends of the U-shaped handrail 7 have plug holes. The plug-in ends cooperate with the plug holes to realize the detachable connection between the U-shaped handrail 7 and the first support rod 1 and the second support rod 2.

[0046] To prevent the U-shaped handrail 7 from falling off the first support rod 1 and the second support rod 2, a threaded hole can be provided at the bottom of the insertion hole of the U-shaped handrail 7, and bolts can be provided on the insertion ends of the first support rod 1 and the second support rod 2. The connection between the U-shaped handrail 7 and the first support rod 1 and the second support rod 2 can be strengthened by the threaded connection of the bolts and the threaded hole.

[0047] This utility model also provides a seat cushion assembly, including a seat cushion bracket according to one embodiment, and a seat cushion adapted to the seat cushion bracket.
