Detailed Description

The core of the invention is to provide a gear handle of a motor vehicle, which can be detached and separated from each other, thereby achieving the purpose of convenient maintenance.

In order to make those skilled in the art better understand the technical solution of the present invention, the following detailed description will be made on the vehicle gear lever and the transmission case of the present application with reference to the accompanying drawings and specific embodiments.

FIG. 1 is an exploded view of the overall structure of a vehicle gear lever handle according to the present invention; fig. 2A is a longitudinal sectional structural view of the gear lever provided by the present invention in a completely assembled state, and fig. 2B is a transverse sectional structural view. This gear handle includes axis of

rotation

1 and 3 isotructures of cartridge seat, and wherein 1 middle part of axis of rotation sets up rotation center, and axis of rotation 1 can rotate around the rotation center that the level set up, realizes vertical rotation in the plane through rotation center, and the switching that different fender position were realized to different angles in axis of rotation 1 rotation. The side wall of the upper part of the rotating shaft 1 is provided with a clamping structure protruding outwards, and the clamping structure is matched with other structures to realize clamping.

The plug-in mounting seat 3 is provided with a groove, the opening of the groove faces downwards, and the shape of the groove is matched with that of the rotating shaft 1 and is used for being sleeved on the top of the rotating shaft 1. Set up the deformation in cartridge seat 3's the recess, the deformation can with the axis of rotation 1 on the joint structure cooperation joint that sets up, make axis of rotation 1 and cartridge seat 3 keep mutual joint fixed, but still can alternate segregation, take place to warp through the deformation and remove the locking, this process is reversible, can not produce destructive influence to the locking structure, can repeatedly lock the process fixed with the separation.

According to the invention, the plug-in mounting seat 3 is sleeved on the rotating shaft 1, and the plug-in mounting seat 3 and the rotating shaft 1 are fixed in a clamping manner, so that clamping structures can be separated from each other, and therefore, the plug-in mounting seat 3 can be independently detached from the rotating shaft 1, as shown in fig. 3, the structure diagram is shown when the plug-in mounting seat 3 and the rotating shaft 1 are separated from each other. The lower line section can be exposed by removing the cartridge 3, and maintenance can be performed without removing the panel.

On the basis, the gear lever of the motor vehicle further comprises a bushing 2 fixedly connected with the rotating shaft 1, the bushing 2 is sleeved on the top of the rotating shaft 1, as shown in fig. 1, the bushing 2 is of a vertically-through cylindrical structure and can be sleeved on the outer side above the rotating shaft 1, the bushing 2 and the rotating shaft 1 can be fixed with each other through bolts, and the bushing 2 and the rotating shaft 1 are connected to form a whole. The rotating shaft 1 and the bushing 2 may be made of a metal material to achieve sufficient structural strength. The joint structure is for setting up hasp 21 on 2 both sides outer walls of bush, and hasp 21 sets up two at least, is the symmetric distribution. Since the bush 2 and the rotary shaft 1 are fixed to each other as a single body, the snap 21 on the bush 2 can be regarded as being indirectly provided on the rotary shaft 1. The bush 2 is used for increasing the distance between the two hasps 21, so that the two hasps can be directly arranged on the rotating shaft 1, but the structure of the rotating shaft 1 is more complicated, materials are wasted, and the complicated structure is not convenient to manufacture.

The rotating shaft 1 is a metal shaft and is in an I-shaped structure, so that the bending resistance of rotation in a rotating plane is improved. The bush 2 suit is in the I-shaped structure, and both pass through bolt reciprocal anchorage, and metal bush 2 includes two planes and two arcwall faces, laminates with the outward appearance of axis of rotation 1 each other, and relative rotation can not appear between bush 2 and the axis of rotation 1.

Specifically, the snap 21 is a triangular projection in cross section, the snap 21 is respectively protruded toward both sides of the bushing 2, and is formed by two side surfaces which are respectively inclined upward and downward, the cartridge holder 3 is fitted on the outer side of the rotating shaft 1, and the downward inclined side surfaces function to catch the cartridge holder 3, so that the slope of the downward inclined side surfaces of the snap 21 is greater than the slope of the upward inclined side surfaces in order to prevent the cartridge holder 3 from being easily pulled out. Enough locking force can be kept during clamping, the slope is adjusted to be proper, the clamping device cannot be pulled out manually, and the clamping device can be detached only by means of a tool.

As shown in fig. 4, which is a partially enlarged view of the circled portion in fig. 2A. The deformation piece is clamping ring 31, and clamping ring 31 is the U type, and the both sides branch can take place to separate each other and warp to the both sides separation. The limiting groove 32 used for accommodating the clamping ring 31 is formed in the inner wall of the groove of the plug-in mounting seat 3, the limiting groove 32 is the same as the clamping ring 31 in shape, the clamping ring 31 can be placed in the limiting groove 32 right, two sides of the limiting groove 32 can prevent the clamping ring 31 from moving upwards or downwards, and the expansion amplitude of the clamping ring 31 towards two sides is limited. The size of the lower edge of the limiting groove 32 is larger than that of the upper edge, and the protruding length of the upper edge is small, so that the limiting groove is used for avoiding the hasp 21 and cannot cause interference on the hasp 21. The snap ring 31 is not limited to the U shape, and the same technical effect can be achieved as long as it is a non-closed structure with a notch.

On the basis of any one of the technical schemes and the mutual combination thereof, the invention also comprises a ball head 4 detachably connected to the top of the plug-in mounting seat 3 through a buckle, a thermistor pad 41 is arranged between the ball head 4 and the plug-in mounting seat 3, the thermistor pad 41 is arranged on the PCB 42, and power is supplied to the PCB 42 through the PCB.
