[0027] See Figure 1 As shown, this embodiment provides a steering mechanism for a bicycle, including a steering cross bar 1 provided at the front part of the bicycle body, a left steering tie rod assembly 2 whose front end is rotatably connected to the left end of the steering cross bar 1, and a right steering tie rod assembly 3 whose front end is rotatably connected to the right end of the steering cross bar 1. A left limiting assembly 4 for limiting the movement of the left steering tie rod assembly 2 in the front-rear direction and a right limiting assembly 5 for limiting the movement of the right steering tie rod assembly 3 in the front-rear direction are provided on the bicycle body.
[0028] Specifically, a front fork 8 for connecting a front wheel 9 is provided at the front part of the bicycle body. The steering cross bar 1 is connected directly above the front fork 8 and can rotate around an axis line arranged vertically, so as to drive the front wheel 9 connected to the front fork 8 to turn.
[0029] In this embodiment, the bicycle is a recumbent type, and the user's hands are located near the middle part of the bicycle body and are used to respectively hold the rear ends of the left steering tie rod assembly 2 and the right steering tie rod assembly 3.
[0030] The left steering rod assembly 2 includes a left steering rod 21 disposed in the left limiting assembly 4 in the front-rear direction, and a left steering swing rod 22 rotatably connected to the left end of the steering cross bar 1 and the front end of the left steering rod 21 at its front and rear ends respectively; the right steering rod assembly 3 includes a right steering rod 31 disposed in the right limiting assembly 5 in the front-rear direction, and a right steering swing rod 32 rotatably connected to the right end of the steering cross bar 1 and the front end of the right steering rod 31 at its front and rear ends respectively. By respectively operating the front and rear movements of the left steering rod 21 and the right steering rod 31, the rotation of the steering cross bar 1 around the vertically arranged axis can be controlled, thereby controlling the steering of the front wheel 9.
[0031] In this embodiment, the movement direction of the left steering rod 21 is parallel to the movement direction of the right steering rod 31, and parallel to the central axis of the bicycle in the front-rear direction, that is, the left steering rod 21 can move along its length extension direction (i.e., along the forward direction of the bicycle), and the right steering rod 31 can also move along its length extension direction (i.e., along the forward direction of the bicycle).
[0032] In this way, the swinging movements of the left steering rod 21 and the right steering rod 31 around their front ends can be adjusted into linear movements. When the steering rods are manipulated to move back and forth, through the cooperation of the steering swing rods, the outward or inward swinging of the steering rods can be avoided, so as to prevent the steering rods from obliquely extending outward to collide with the vehicle shell or obliquely extending inward to collide with the human body, greatly reducing the control difficulty and increasing the riding experience of the user.
[0033] In this embodiment, the rotation axis lines at both ends of the left steering swing rod 22 are parallel to each other and parallel to the rotation axis line of the steering cross bar 1; the rotation axis lines at both ends of the right steering swing rod 32 are parallel to each other and parallel to the rotation axis line of the steering cross bar 1.
[0034] See Figure 1 As shown, in the initial state, the left steering swing rod 22 intersects the steering cross bar 1 and the left steering rod 21 at a certain angle respectively, and the right steering swing rod 32 intersects the steering cross bar 1 and the right steering rod 31 at a certain angle respectively. Through this setting, it can be ensured that the left steering rod 21 and the right steering rod 31 can move back and forth a sufficient distance respectively to support the steering of the bicycle.
[0035] The left limit component 4 includes at least one left limit member 41 disposed on the left side of the bicycle body. A left limit ring 42 for the left steering rod 21 to pass through is provided on the left limit member 41. The left limit member 41 and the left limit ring 42 are integrally formed or fixedly connected; the right limit component 5 includes at least one right limit member 51 disposed on the right side of the bicycle body. A right limit ring 52 for the right steering rod 31 to pass through is provided on the right limit member 51. The right limit member 51 and the right limit ring 52 are integrally formed or fixedly connected. Wherein, the inner diameter of the left limit ring 42 is the same as the outer diameter of the left steering rod 21, and there is a certain tolerance for this dimension to ensure that the left steering rod 21 can freely move along the axis of the inner hole of the left limit ring 42; the inner diameter of the right limit ring 52 is the same as the outer diameter of the right steering rod 31, and there is a certain tolerance for this dimension to ensure that the right steering rod 31 can freely move along the axis of the inner hole of the right limit ring 52.
[0036] In this embodiment, there are two left limit members 41 and two right limit members 51 respectively. The arrangement directions of the two left limit members 41 are parallel to the arrangement directions of the two right limit members 51 and parallel to the central axis of the bicycle in the front-rear direction. The two left limit members 41 and the two right limit members 51 can be aligned one by one in the left-right direction or arranged alternately in sequence. The advantage of respectively arranging two left limit members 41 and two right limit members 51 is that the steering rod is more stable and reliable when moving back and forth, and the material of the steering rod can also be selected according to needs to reduce the overall weight of the bicycle.
[0037] In other embodiments, according to the actual situation of the bicycle, the movement directions of the left steering rod 21 and the right steering rod 31 can be arranged at an arbitrary angle. The left steering rod 21 can move along its length extension direction, and the right steering rod 31 can move along its length extension direction. The arrangement directions of the left limit member 41 and the right limit member 51 are respectively consistent with the movement directions of the left steering rod 21 and the right steering rod 31. In this way, in actual applications, there can be various steering structure selections. Of course, due to the left steering swing rod 22 and the right steering swing rod 32 provided in the structure, when the left steering rod 21 and the right steering rod 31 control the bicycle to turn, the angles between them and the vehicle shell or the human body are controllable, which can avoid hitting the vehicle shell when extending obliquely outwards or hitting the human body when extending obliquely inwards.
[0038] See Figure 1 As shown, the above-mentioned steering mechanism further includes a left handle 6 provided at the rear end of the left steering rod 21 and a right handle 7 provided at the rear end of the right steering rod 31. The left handle 6 and the right handle 7 are respectively arranged in the up-down direction. Through this setting, the width of the closed shell at the handle can be narrowed, the height of the closed shell at the handle can be reduced, and consumables can be saved; it also reduces the width of the bicycle, lightens the weight, is convenient for the user to hold and control the handle; at the same time, it can also avoid the closed shell being too high and affecting the riding vision, making the riding safer.
[0039] In this embodiment, the left handle 6 and the left steering tie rod 21 are integrally formed, and the left handle 6 is formed by bending downward the rear side rod body of the left steering tie rod 21; the right handle 7 and the right steering tie rod 31 are integrally formed, and the right handle 7 is formed by bending downward the rear side rod body of the right steering tie rod 31.
[0040] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and it cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
