[0036] The embodiments of the utility model are described in detail below, and the examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.
[0037] As Figure 1 Indicated, the vehicle head assembly of the embodiments of the utility model includes outer stand pipe 1, inner stand pipe 2, connector 3, first reinforcing part 4, front fork 5 and fastener 6.
[0038] Outer stand pipe 1 is set on the outer circumferential side of inner stand pipe 2. For example, as Figure 1As shown, the outer stand pipe 1 and the inner stand pipe 2 can be in a circular tube shape, wherein the pipe diameter of the outer stand pipe 1 is larger than that of the inner stand pipe 2, the inner stand pipe 2 can be assembled in the outer stand pipe 1, the inner stand pipe 2 and the outer stand pipe 1 are arranged coaxially, and an annular cavity is formed between the inner stand pipe 2 and the outer stand pipe 1.
[0039] The connecting piece 3 is connected between one end of the inner stand pipe 2 and the outer stand pipe 1, and the first reinforcing piece 4 is connected between the other end of the inner stand pipe 2 and the outer stand pipe 1. For example, as shown in Figure 1 As shown, the inner stand pipe 2 and the outer stand pipe 1 can be arranged vertically, wherein the length dimension of the inner stand pipe 2 is shorter than that of the outer stand pipe 1. The top end of the inner stand pipe 2 and the top end of the outer stand pipe 1 can be generally flush, and the bottom end of the inner stand pipe 2 can be located in the outer stand pipe 1.
[0040] The connecting piece 3 can be in a plate structure, a rod structure, a mesh structure, etc. The connecting piece 3 can be arranged in the annular space between the inner stand pipe 2 and the outer stand pipe 1, and the connecting piece 3 is connected and fixed with the inner stand pipe 2 and the outer stand pipe 1. The specific connection and fixing mode can be welding, bonding, etc., and the connecting piece 3 can be arranged adjacent to the bottom end of the inner stand pipe 2.
[0041] The first reinforcing piece 4 can be in a plate structure, and the first reinforcing piece 4 can be arranged at the top end of the inner stand pipe 2 and the outer stand pipe 1. The first reinforcing piece 4 can be welded and fixed with the inner stand pipe 2 and the outer stand pipe 1. In this way, the inner stand pipe 2 and the outer stand pipe 1 can be connected as a whole by the connecting piece 3 and the first reinforcing piece 4 to form a frame structure, which meets the use needs of the integrated arrangement of the inner stand pipe 2 and the outer stand pipe 1 and has high structural strength.
[0042] The front fork 5 is inserted and matched in the inner stand pipe 2. For example, as shown in Figure 1 As shown, the front fork 5 can include a pipe portion, which can be arranged vertically and inserted into the inner hole of the inner stand pipe 2 from below, thereby facilitating the connection and fixation of the front fork 5 and the inner stand pipe 2.
[0043] The fastener 6 penetrates the inner stand pipe 2 and the front fork 5 to connect and fix the inner stand pipe 2 and the front fork 5, and the fastener 6 is located in the outer stand pipe 1. For example, as shown in Figure 1 As shown, the fastener 6 can be a bolt, etc. The fastener 6 can be arranged along the radial direction of the inner stand pipe 2. During assembly, the fastener 6 can penetrate the inner stand pipe 2 and the pipe portion of the front fork 5 at the same time and connect and fix the two. After assembly, the fastener 6 can be hidden in the outer stand pipe 1 as a whole.
[0044] In this embodiment of the vehicle head assembly, the inner riser 2 can be connected and fixed to the front fork 5, while the outer riser 1 can conceal the fastener 6 used to connect the inner riser 2 and the front fork 5 within it. This avoids the fastener 6 and the connection position between the front fork 5 and the inner riser 2 being exposed, thus improving the overall appearance. Because the connection position is hidden and shielded, it also prevents foreign objects from touching the connection position, improving the anti-interference capability of the connection position.
[0045] In addition, by setting up an outer riser 1 and an inner riser 2 in a nested manner, compared to the original situation of setting only one riser, the overall pipe diameter is increased, thereby ensuring the overall structural strength.
[0046] In some embodiments, the inner riser 2 is provided with a nut 21, and a fastener 6 is threadedly fitted into the nut 21. For example, as Figure 2 As shown, the nut 21 can be welded and fixed to the inner riser 2, and the fastener 6 can be a bolt. During assembly, the fastener 6 can be directly threaded onto the nut 21, thereby improving the convenience of assembly.
[0047] In some embodiments, the inner riser 2 is provided with at least one first hole 22 and at least one second hole 23 arranged opposite to each other. The fastener 6 passes through the first hole 22 and the second hole 23. The nut 21 is provided on the outside of the inner riser 2 and is embedded in the first hole 22. The end 61 of the fastener 6 is embedded in the second hole 23.
[0048] For example, such as Figure 2 As shown, both the first hole 22 and the second hole 23 can extend along the radial direction of the inner riser 2, and both the first hole 22 and the second hole 23 can penetrate the wall of the inner riser 2. The first hole 22 can be located on the front side of the inner riser 2, and the second hole 23 can be located on the rear side of the inner riser 2, that is, the first hole 22 and the second hole 23 can be arranged facing each other in the front-rear direction.
[0049] The aforementioned nut 21 can be welded and fixed to the front wall of the inner riser 2, and a portion of the nut 21 can be embedded in the first hole 22, thereby enhancing the connection and fixing effect of the nut 21.
[0050] The end 61 of the fastener 6 can be a bolt head. During assembly, the fastener 6 can pass through the second hole 23 and be threaded into the first hole 22. A portion of the end 61 of the fastener 6 can be embedded in the second hole 23. The constraint effect on the fastener 6 can be enhanced by the limiting fit with the second hole 23, thereby further improving the structural stability of the assembly.
[0051] In some embodiments, the outer riser 1 is provided with at least one third hole 11, which is arranged opposite to the second hole 23, and the diameter of the third hole 11 is greater than or equal to the radial dimension of the end 61 of the fastener 6.
[0052] For example, as shown in Figure 2 the third hole 11 can pass through the pipe wall of the outer stand pipe 1 along the radial direction of the outer stand pipe 1. The third hole 11 can be arranged opposite to the second hole 23 in the front-rear direction, and the third hole 11 can be located behind the second hole 23. Both the second hole 23 and the third hole 11 can be circular holes, wherein the radial dimension of the third hole 11 is greater than the radial dimension of the second hole 23. Thus, the fastener 6 can pass through the third hole 11 and connect and fix the inner stand pipe 2 and the front fork 5.
[0053] In some embodiments, the outer stand pipe 1 is provided with at least one fourth hole 12, the fourth hole 12 is arranged opposite to the first hole 22, and the hole diameter of the fourth hole 12 is smaller than the hole diameter of the third hole 11. For example, as shown in Figure 2 the fourth hole 12 can pass through the pipe wall of the outer stand pipe 1 along the radial direction of the outer stand pipe 1, and the fourth hole 12 and the first hole 22 can be arranged opposite in the front-rear direction, wherein the fourth hole 12 can be located in front of the first hole 22.
[0054] Both the fourth hole 12 and the third hole 11 can be circular holes, wherein the radial dimension of the fourth hole 12 is smaller than the radial dimension of the third hole 11. Specifically, the hole diameter of the fourth hole 12 can be generally equivalent to the shank portion of the fastener 6, so that on the one hand, the fourth hole 12 can play a role in avoiding the fastener 6, facilitating the assembly of the fastener 6 in place, and on the other hand, the assembly of the fastener 6 can also be observed through the fourth hole 12. In addition, when disassembling, a tool such as a screwdriver can also be inserted into the outer stand pipe 1 through the fourth hole 12 and push the fastener 6, thereby facilitating the disassembly of the fastener 6.
[0055] In some embodiments, as shown in Figure 2 the head assembly includes a spring pad 62, for example, the material of the spring pad 62 can be rubber or the like, the spring pad 62 can be circular ring-shaped, the spring pad 62 is sleeved on the outer circumferential side of the fastener 6, and the spring pad 62 is clamped and fixed between the front fork 5 and the end head 61 of the fastener 6. Thus, the rigid contact between the end head 61 of the fastener 6 and the front fork 5 can be avoided, and the spring pad 62 can also increase the pre-tightening effect by the elastic force of the spring pad 62, thereby ensuring the structural stability of the assembly.
[0056] In some embodiments, the connecting piece 3 is a ring-shaped plate, the ring-shaped plate is arranged on the outer circumferential side of the inner stand pipe 2, and the inner circumferential edge of the ring-shaped plate is connected with the inner stand pipe 2, and the outer circumferential edge of the ring-shaped plate is connected with the outer stand pipe 1.
[0057] For example, as shown in Figure 2As shown, the annular plate can be circular, and the inner peripheral edge of the annular plate can be connected and fixed with the inner standpipe 2 by welding, and the outer peripheral edge of the annular plate can also be connected and fixed with the outer standpipe 1 by welding. In this way, the supporting and limiting effect of the inner standpipe 2 and the outer standpipe 1 in any direction in the circumferential direction can be realized, and the connection structure strength between the two can also be ensured.
[0058] In some embodiments, the vehicle head assembly includes a handlebar 7, and the first reinforcing member 4 is blocked outside the pipe openings of the outer standpipe 1 and the inner standpipe 2, and the first reinforcing member 4 is provided with a protruding portion 41 which protrudes inwardly from the inner standpipe 2 and forms a fitting groove on the outside of the first reinforcing member 4, and the handlebar 7 is fitted in the fitting groove.
[0059] For example, as shown in the drawings, Figure 1 The first reinforcing member 4 can be a plate structure, and the first reinforcing member 4 can be welded and fixed at the top end of the inner standpipe 2 and the outer standpipe 1, and the first reinforcing member 4 can seal and block the top end pipe openings of the inner standpipe 2 and the outer standpipe 1, thereby ensuring the overall structural strength and sealing performance, and avoiding the situation that liquid easily enters the outer standpipe 1 and the inner standpipe 2 and easily corrodes and causes short circuit of the built-in circuit.
[0060] As shown in the drawings, Figure 1 A middle portion of the first reinforcing member 4 can protrude downward and form a protruding portion 41, and the top side of the protruding portion 41 can be recessed and form a fitting groove, and the handlebar 7 of the vehicle can be embedded in the fitting groove, and the handlebar 7 can be welded and fixed with the first reinforcing member 4, thereby ensuring the structural stability of the handlebar 7 assembly.
[0061] In some embodiments, the vehicle head assembly includes two second reinforcing members 10, which are symmetrically arranged on both sides of the outer standpipe 1, and each second reinforcing member 10 is connected and fixed in the included angle formed by the handlebar 7 and the outer standpipe 1.
[0062] For example, as shown in the drawings, Figure 3 The second reinforcing member 10 can be an arc-shaped plate, and the two second reinforcing members 10 can be respectively arranged on the left and right sides of the outer standpipe 1 in the left-right direction. When the handlebar 7 is welded and fixed with the first reinforcing member 4, one second reinforcing member 10 can be welded and fixed at each of the two edge angles formed by the handlebar 7 and the outer standpipe 1 in the left-right direction, and each second reinforcing member 10 is welded and fixed with the handlebar 7 and the outer standpipe 1, thereby ensuring the connection strength and structural stability between the handlebar 7 and the outer standpipe 1.
[0063] In some embodiments, as shown in the drawings, Figure 2 The vehicle head assembly includes a head tube 9 and a cylinder bush 8, the cylinder bush 8 is sleeved on the outer peripheral side of the front fork 5 and clamped between the outer standpipe 1 and the head tube 9, and the cylinder bush 8 is specifically an upper cylinder bush 8 of the vehicle, and the cylinder bush 8 mainly plays a role in adjusting the assembly error between the head tube 9 and the outer standpipe 1.
[0064] The outer diameter size of the head tube 9 is consistent with the outer diameter size of the outer stand tube 1, for example, as shown in the figure, the outer diameter size of the head tube 9 can be size D2, the outer diameter size of the outer stand tube 1 can be size D1, size D1 is equal to size D2, so as to ensure the overall appearance, avoid the step between the two, and ensure the flatness of the outer surface. Figure 2
[0065] In some embodiments, the pipe wall thickness of the inner stand tube 2 is greater than the pipe wall thickness of the outer stand tube 1. For example, as shown in the figure, the pipe wall thickness of the inner stand tube 2 can be size M1, the pipe wall thickness of the outer stand tube 1 can be size M2, size M1 is greater than size M2. Since the inner stand tube 2 is used to be connected with the front fork 5, the inner stand tube 2 adopts the material with thick pipe wall to fully ensure the structural strength of the connection. Since the outer stand tube 1 mainly plays the role of outer decoration, the material with thin thickness is adopted to reduce the overall cost. Figure 2
[0066] Optionally, size M1 can be 2.5mm, and size M2 can be 1.5mm.
[0067] In some embodiments, the front fork 5 is clearance fitted in the inner stand tube 2. For example, after the front fork 5 is inserted into the inner stand tube 2, the front fork 5 and the inner stand tube 2 can have a clearance of 0.1mm. Thus, the smooth insertion and connection of the front fork 5 and the inner stand tube 2 is facilitated.
[0068] In some embodiments, the fastener 6 is provided in plurality, and the plurality of fasteners 6 are arranged in parallel and spaced apart along the extension direction of the inner stand tube 2.
