[0027] The rotor component 20 includes a ball rack 201 , a ball groove 202 , a steel ball 203 , a slope portion 204 , and a positioning protrusion 30 . DETAILED DESCRIPTION

[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] The existing fork bowl assembly generally includes a head bowl, a steel ball rotating frame and an open buckle. After the steel ball rotating frame is installed in the head bowl, the open buckle is inserted into the head bowl, thereby limiting the axial position of the steel ball rotating frame in the head bowl. On the one hand, the assembly efficiency of the fork bowl assembly with this structure is low, and on the other hand, the bowl assembly has more parts, and there is still room for improvement in cost control.

[0032] Based on the above situation, an embodiment of the utility model provides a front fork headset and a vehicle, which are described in detail below in conjunction with specific embodiments and drawings.

[0033] Example 1

[0034] An embodiment of the utility model provides a front fork bowl set. Figure 1 It is a schematic diagram of the three-dimensional structure of a front fork headset according to an exemplary embodiment. Figure 2is a front view of a fork bowl assembly structure according to an exemplary embodiment. Figure 1-2 As shown, the front fork bowl assembly is assembled with a front fork stem, specifically, it includes a head bowl 10, a stem hole 103 for sleeved on a front fork stem is opened in the middle of the bottom of the head bowl 10, and further, the edge of the open side of the head bowl 10 is integrally extended to form a ring-shaped bowl edge 102, and is assembled with a vehicle, and also includes:

[0035] There are several positioning protrusions 30, which are formed on the upper part of the inner wall of the head bowl 10; Figure 1-2 In this embodiment, the positioning protrusion 30 is formed by a stamping process. During the stamping process, the punch head enters from the open side of the head bowl 10 and gradually punches the inner wall of the bowl of the head bowl 10. During this process, the contact part of the punch head is deformed and protrudes to form the positioning protrusion 30. The processing process of this positioning protrusion 30 is simple and convenient, and the processing cost is low.

[0036] The rotor member 20 is assembled inside the head bowl 10, and its lower end is in active contact with the rotor slot 101 formed inside the head bowl 10, and its upper end is in contact with the lower part of the positioning protrusion 30 for axial positioning;

[0037] In this embodiment, Figure 3 The three-dimensional structure explosion of the front fork bowl assembly is shown according to an exemplary embodiment. Figure 1 . Figure 4 The three-dimensional structure explosion of the front fork bowl assembly is shown according to an exemplary embodiment. Figure 2 . Refer to the attached Figure 1-4 The rotor member 20 comprises: a ball rack 201, which is annular and has a plurality of ball slots 202 distributed in an annular array at its lower portion; a plurality of steel balls 203, which are respectively rolled and assembled in the ball slots 202;

[0038] Among them, the bottom end and outer end of the steel ball 203 after assembly extend to the outside of the ball groove 202 to roll with the inner wall of the head bowl 10, and the upper end of the ball rack 201 after assembly abuts against the lower part of the positioning protrusion 30; the inner end of the steel ball 203 after assembly extends to the outside of the ball groove 202 and rolls with the side wall of the front fork stem.

[0039] In the technical solution of the above embodiment, a plurality of positioning protrusions 30 are provided on the upper part of the inner wall of the head bowl 10 to replace the traditional open clip press-in fixation. After the ball rack 201 is installed, the bottom end and the outer end of the steel ball 203 are in rolling contact with the inner wall of the head bowl 10, and the upper end of the ball rack 201 abuts against the lower part of the positioning protrusion 30. This ensures that the rotor part 20 is axially fixed in the head bowl 10, effectively reduces the cost of parts, and the processing is simple and convenient. In this way, the processing production and assembly efficiency are optimized.

[0040] Optionally, refer to the attached Figure 1-2 The number of the positioning protrusions 30 is three. In the actual test process, at least two positioning protrusions 30 are used to achieve basic positioning of the rotor member 20, but there is still a risk of detachment. Using more than three positioning protrusions 30 may cause more small gaps in the assembly between the head bowl 10 and the front fork stem, slightly affecting the assembly effect. Therefore, the preferred number of positioning protrusions 30 is three.

[0041] Optionally, refer to the attached Figure 4 The lower part of the annular outer wall of the ball rack 201 is formed with a slope portion 204 that shrinks from top to bottom to cooperate with assembly. Specifically, the rotor component 20 is assembled into the head bowl 10 from the open side of the head bowl 10. During the installation process, the slope portion 204 of the ball rack 201 abuts against the positioning protrusion 30, and gradually presses the ball rack 201 during the installation process, slightly deforming and smoothly transitioning until the ball rack 201 is installed. The bottom and outer ends of the steel balls 203 roll in contact with the inner wall of the head bowl 10, and the upper end of the ball rack 201 abuts against the lower part of the positioning protrusion 30 to axially position the rotor component 20. At this time, the ball rack 201 recovers after deformation, and assembly is more convenient.

[0042] In summary, the front fork bowl assembly provided by the embodiment of the utility model, by arranging a plurality of positioning protrusions 30 on the upper part of the inner wall of the head bowl 10 to replace the traditional open clip press-in fixation, ensures that the rotor part 20 is axially fixed in the head bowl 10, effectively reduces the cost of parts, and is simple and convenient to process. In this way, the processing production and assembly efficiency are optimized.
