[0027] Please refer to Figure 1 、 Figure 2 and Figure 3 , this embodiment provides a steering structure 100 for an electric vehicle, including a steering gear 110 and a head tube 120. The head tube 120 is used to connect to the vehicle frame. The steering gear 110 includes a connecting plate 111, and columns 112 and shock absorbers 113 connected to both sides of the connecting plate 111. The columns 112 are inserted into the head tube 120 and the columns 112 are rotatably connected to the head tube 120. A rubber sleeve 114 is inserted on the columns 112, and the rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120.
[0028] When assembling the electric vehicle front fork rotating structure 100 of the present application, a column 112 and a shock absorber 113 are respectively installed on both sides of the connecting plate 111. One end of the column 112 away from the connecting plate 111 is used to connect the steering gear 110. Subsequently, a rubber sleeve 114 is sleeved on the column 112, and then the head tube 120 is sleeved on the column 112. The rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120, so that rainwater will not erode the joint between the head tube 120 and the connecting plate 111, and rainwater will not enter the head tube 120 through the joint, resulting in the steering gear 110 being stuck during rotation, thereby ensuring the stable rotation of the electric vehicle front fork rotating structure 100.
[0029] The electric vehicle front fork rotating structure 100 provided by the present application includes a steering gear 110 and a head tube 120. The head tube 120 is used to be connected to the vehicle frame. The steering gear 110 includes a connecting plate 111, and a column 112 and a shock absorber 113 connected to both sides of the connecting plate 111. The column 112 is arranged inside the head tube 120 and the column 112 is rotatably connected to the head tube 120. A rubber sleeve 114 is arranged on the column 112. The rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120, so that rainwater will not enter the head tube 120 through the joint between the head tube 120 and the connecting plate 111, resulting in the steering gear 110 being stuck during rotation, thereby ensuring the stable rotation of the electric vehicle front fork rotating structure 100.
[0030] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, a plurality of buffer layers 1141 are arranged in a corrugated shape on the outer ring of the rubber sleeve 114 along the extending direction of the head tube 120.
[0031] Specifically, a plurality of buffer layers 1141 are arranged in a corrugated shape on the outer ring of the rubber sleeve 114 to ensure the structural stability of the rubber sleeve 114.
[0032] Among them, the buffer layer 1141 can be set to three layers, four layers, five layers or six layers.
[0033] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, the outer diameters of the plurality of buffer layers 1141 are different.
[0034] Specifically, the outer diameters of the plurality of buffer layers 1141 are set to be different to ensure that the buffer layer 1141 guides rainwater at different positions.
[0035] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, from the extending direction of the column 112 to the shock absorber 113, the outer diameter of the buffer layer 1141 gradually increases.
[0036] In the extending direction from the upright column 112 to the shock absorber 113, the outer diameter of the buffer layer 1141 gradually increases. When the front fork rotating structure 100 of the electric vehicle is installed on the electric vehicle, the upright column 112 is above the shock absorber 113. The upright column 112 is connected to the steering gear 110, and the shock absorber 113 is connected to the wheel. Rainwater first falls on the uppermost buffer layer 1141. From top to bottom, the outer diameter of the buffer layer 1141 gradually increases. The rainwater on the uppermost buffer layer 1141 falls downward in sequence. The rainwater is guided layer by layer through the multiple buffer layers 1141 to ensure that the rainwater does not erode the joint between the head tube 120 and the connecting plate 111, and the rainwater does not enter the head tube 120 through the joint, causing the steering gear 110 to rotate and jam, thereby ensuring the stable rotation of the front fork rotating structure 100 of the electric vehicle.
[0037] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, a diversion inclined surface 1141a is provided on the outer wall of the buffer layer 1141. The water flow on the buffer layer 1141 is guided to the outer ring of the buffer layer 1141 through the diversion inclined surface 1141a.
[0038] Specifically, rainwater first falls on the uppermost buffer layer 1141. A diversion inclined surface 1141a is provided on each buffer layer 1141. The water flow on the buffer layer 1141 is guided to the outer ring of the buffer layer 1141 through the diversion inclined surface 1141a. The rainwater on the outer ring falls into the diversion inclined surface 1141a of the next-layer buffer layer 1141. From top to bottom, the outer diameter of the buffer layer 1141 gradually increases. Falling in this way in sequence, the rainwater on the uppermost buffer layer 1141 falls downward in sequence. The rainwater is guided layer by layer through the multiple buffer layers 1141 to ensure that the rainwater does not erode the joint between the head tube 120 and the connecting plate 111, and the rainwater does not enter the head tube 120 through the joint, causing the steering gear 110 to rotate and jam, thereby ensuring the stable rotation of the front fork rotating structure 100 of the electric vehicle.
[0039] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3 shown, a plurality of convex blocks 1142 are arranged at intervals on the inner wall of the rubber sleeve 114. The convex blocks 1142 support the connecting plate 111 and the head tube 120.
[0040] Specifically, convex blocks 1142 are arranged on the inner wall of the rubber sleeve 114 to support the connecting plate 111 and the head tube 120 through the convex blocks 1142, thereby ensuring the stable support of the connecting plate 111.
[0041] In a feasible embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3As shown, a drainage channel 1143 is formed between two adjacent bumps 1142.
[0042] Specifically, a drainage channel 1143 is formed between two adjacent bumps 1142. When rainwater enters the rubber sleeve 114 through the joint between the rubber sleeve 114 and the head tube 120, it will enter the drainage channel 1143 between two adjacent bumps 1142 and be discharged through the joint between the rubber sleeve 114 and the connecting plate 111.
[0043] In a feasible embodiment of the present application, as Figure 1 , Figure 2 and Figure 3 shown, a steering bearing is provided between the head tube 120 and the column 112, and the head tube 120 and the column 112 are rotatably connected through the steering bearing.
[0044] Specifically, when assembling the electric vehicle front fork rotating structure 100 of the present application, the column 112 and the shock absorber 113 are respectively installed on both sides of the connecting plate 111. One end of the column 112 away from the connecting plate 111 is used to connect the steering gear 110. Subsequently, the rubber sleeve 114 is sleeved on the column 112, the steering bearing is installed in the head tube 120, and then the head tube 120 is sleeved on the column 112, so that the head tube 120 and the column 112 are rotatably connected through the steering bearing. The rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120, so that rainwater will not erode the joint between the head tube 120 and the connecting plate 111, and rainwater will not enter the head tube 120 through the joint to cause the steering gear 110 to rotate and jam, thereby ensuring the stable rotation of the electric vehicle front fork rotating structure 100.
[0045] In a feasible embodiment of the present application, as Figure 1 , Figure 2 and Figure 3 shown, the steering bearing includes a first steering bearing and a second steering bearing provided in the head tube 120, and the first steering bearing and the second steering bearing are located at both ends of the head tube 120.
[0046] Specifically, when assembling the electric vehicle front fork rotating structure 100 of the present application, the column 112 and the shock absorber 113 are respectively installed on both sides of the connecting plate 111. One end of the column 112 away from the connecting plate 111 is used to connect the steering gear 110. Subsequently, the rubber sleeve 114 is sleeved on the column 112, the first steering bearing and the second steering bearing are installed in the head tube 120, and then the head tube 120 is sleeved on the column 112, so that the head tube 120 and the column 112 are rotatably connected through the first steering bearing and the second steering bearing. The rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120, so that rainwater will not erode the joint between the head tube 120 and the connecting plate 111, and rainwater will not enter the head tube 120 through the joint to cause the steering gear 110 to rotate and jam, thereby ensuring the stable rotation of the electric vehicle front fork rotating structure 100.
[0047] In a feasible embodiment of the present application, as Figure 1 , Figure 2 and Figure 3 shown, the shock absorber 113 includes a first shock absorber 1131 and a second shock absorber 1132 disposed on the connecting plate 111, and the front wheel of the electric vehicle is connected through the first shock absorber 1131 and the second shock absorber 1132.
[0048] Specifically, the first shock absorber 1131 and the second shock absorber 1132 of the present application are located on both sides of the front wheel of the electric vehicle and are respectively connected to the front wheel of the electric vehicle, so as to realize the driving of the front wheel of the electric vehicle. The impact force received by the front wheel is buffered through the first shock absorber 1131 and the second shock absorber 1132, and the impact force received by the front wheel is prevented from being directly feedback to the handlebar.
[0049] When assembling the front fork rotation structure 100 of the electric vehicle of the present application, the columns 112 and the shock absorber 113 are respectively installed on both sides of the connecting plate 111. The shock absorber 113 includes a first shock absorber 1131 and a second shock absorber 1132 disposed on the connecting plate 111, and the front wheel of the electric vehicle is connected through the first shock absorber 1131 and the second shock absorber 1132. One end of the column 112 away from the connecting plate 111 is used to connect the steering gear 110. Then, the rubber sleeve 114 is sleeved on the column 112, and the first steering bearing and the second steering bearing are installed in the head tube 120. Then, the head tube 120 is sleeved on the column 112, so that the head tube 120 and the column 112 are rotationally connected through the first steering bearing and the second steering bearing. The rubber sleeve 114 abuts against the connecting plate 111 and the head tube 120, so that rainwater will not erode the joint between the head tube 120 and the connecting plate 111, and rainwater will not enter the head tube 120 through the joint to cause the steering gear 110 to rotate and jam, thereby ensuring the stable rotation of the front fork rotation structure 100 of the electric vehicle.
