[0028] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.
[0029] Reference below Figure 1-Figure 8 A shift handle assembly according to an embodiment of the utility model is described, and the utility model also provides a vehicle.
[0030] Reference Figure 1-8 As shown, the shift handle assembly of the embodiment of the utility model includes: a shift rod, a shift handle ball 10 and an air pipe 20.
[0031] The shift handle ball 10 is arranged above the shift lever. The shift handle ball 10 is a hollow structure. The air pipe 20 is partially arranged inside the shift handle ball 10 and one end of the air pipe 20 is fixedly connected to the shift handle ball 10, and the other end of the air pipe 20 is fixedly connected to the gearbox. Specifically, the shift handle ball 10 refers to a spherical handle in the gearbox of a vehicle, which is used to manually operate the gear position of the gearbox. It is usually located in the center of the driver's seat area of the vehicle and is connected to the gear selection mechanism inside the gearbox through a specific mechanical connection. In the pneumatic shift system involved in the embodiment of the utility model, the high and low gear function conversion of the gearbox sub-box can be realized by connecting one end of the air pipe 20 to the inside of the shift handle ball 10 and the other end to the gearbox.
[0032] The two ends of the air pipe 20 are provided with chamfered parts 21, which are fitted with the inner wall of the shift handle ball 10. That is, after the air pipe 20 is cut, the chamfering process requirements are increased at both ends by a chamfering machine, and the edge burrs at both ends of the air pipe 20 are removed. In this way, when the air pipe 20 is connected to the shift handle ball 10, the problem of damage to the internal structure of the shift handle ball 10 and air leakage of the air pipe 20 caused by sharp edges can be avoided, thereby improving the air tightness of the air pipe 20 and the reliability of the high and low gear function conversion of the vehicle, and to a certain extent, improving the service life of the shift handle ball 10 and the air pipe 20.
[0033] Therefore, by providing chamfered portions 21 at both ends of the air pipe 20, the problem of sharp edges causing damage to the internal structure of the shift handle ball 10 and air leakage in the air pipe 20 can be avoided, thereby improving the air tightness of the air pipe 20 and the reliability of the vehicle's high and low gear function switching, and to a certain extent improving the service life of the shift handle ball 10 and the air pipe 20.
[0034] Reference Figure 2-3 As shown, the shift handle ball 10 is provided with at least two air inlets 11, one of which is a high-speed air inlet and the other is a low-speed air inlet. Specifically, three through holes are provided below the shift handle ball 10, two of which are air inlets 11 for fixed connection with the air pipe 20, one of which is a high-speed air inlet and the other is a low-speed air inlet. Similarly, two air pipes 20 are also provided, one is a high-speed air inlet and the other is a low-speed air inlet. The high-speed and low-speed air pipes 20 are respectively fixed to the high-speed air inlet and the low-speed air inlet to jointly realize the high-speed and low-speed function conversion of the vehicle.
[0035] Reference Figure 2 , Figure 3 and Figure 5 As shown, at least two seals 12 are provided at the air inlet 11, and at least two seals 12 are plugged and matched with the chamfered portion 21. That is, seals 12 are provided at the two air inlets 11 respectively, and the seals 12 can be annular sealing rings. When the air pipe 20 is assembled to the shift handle ball 10, the chamfered portion 21 is inserted into the seal 12 for sealing. The chamfered air pipe 20 will not cause damage to the seal 12, thereby avoiding the problem of air leakage caused by the poor sealing at the connection between the air pipe 20 and the shift handle ball 10, and improving the reliability of the gearbox shifting.
[0036] Reference Figure 6As shown, the chamfered portion 21 includes a guide portion 22 and a platform portion 23, and the guide portion 22 is guided and matched with the seal 12. Specifically, the inclined surface formed at the end of the air pipe 20 after the chamfering process is the guide portion 22, and the platform portion 23 is a plane after the end face of the original air pipe 20 is reduced. When the guide portion 22 contacts the seal 12, it can play a guiding role, so that the air pipe 20 slides along the direction of the guide portion 22 to the correct assembly position, thereby improving the assembly efficiency, avoiding excessive force on one side of the seal 12, and extending its service life.
[0037] Reference Figure 8 As shown, the angle between the guide portion 22 and the vertical plane is α, and α satisfies the relationship: 25°<α<35°. That is, the angle between the guide portion 22 and the vertical plane is between 25° and 35°. In the embodiment of the utility model, the angle between the guide portion 22 and the vertical plane is 30°.
[0038] Reference Figure 7 As shown, the radius of the air pipe 20 is r1, the radius of the platform 23 is r2, and r1 and r2 satisfy the relationship: 0.2mm≤r1-r2≤0.4mm. That is, in the embodiment of the utility model, the distance between the edge of the platform 23 and the edge of the original air pipe 20 is 0.3mm, and the tolerance range is 0.2.
[0039] Reference Figure 5 As shown, at least two elastic members 13 are provided at the air inlet 11, at least two elastic members 13 are spaced apart from the sealing member 12, and the elastic members 13 are plugged and matched with the chamfered portion 21. Specifically, elastic members 13 are provided at both air inlets 11, wherein the elastic members 13 may be retaining springs, and the elastic members 13 are provided on one side of the sealing member 12. When the air pipe 20 is assembled with the shift handle ball 10, the position of the air pipe 20 is first fixed by the elastic member 13, and the air pipe 20 is sealed by contacting the sealing member 12. The chamfered portion 21 of the air pipe 20 is plugged and matched with the elastic member 13, which can prevent the burrs on the edge of the air pipe 20 from getting stuck in the elastic member 13, and avoid the air pipe 20 from being unable to be locked and easily slipping out, thereby improving the reliability of the shift system.
