Description

Technical Field

[0001] The utility model relates to the technical field of gear shifters, in particular to a manual gear shifter for a car. Background Art

[0002] When the speed and gear of a car are not coordinated, the gear needs to be shifted, or when the car is parked or not started, the gear needs to be engaged. Therefore, the gear shifting mechanism is one of the mechanisms that must be used when the car is driving.

[0003] The mainstream equipment of racing cars or sports cars is still manual shifters. In manual shifters, the lower end of the gear lever is universally connected to a fixed base frame through a ball and socket structure, so that different gears can be switched by swinging the gear lever in the left-right direction or the front-back direction. However, the ball and socket structure has a high degree of freedom, which may cause the switching direction to be skewed when the driver swings the gear lever, and is not conducive to the driver's accurate perception, which can easily lead to gear shift errors. Utility Model Content

[0004] The utility model aims to solve the problem that the gear shifter adopting the ball and socket structure in the prior art may cause the switching direction to be skewed when the driver swings the gear lever, which is not conducive to the driver's accurate perception and easily leads to gear shift errors.

[0005] In order to solve the above problems, the utility model provides a manual transmission automobile shifter, including a base frame, a gear lever, a longitudinal axis, a transverse axis and a gear shift bracket, the longitudinal axis is arranged along the front-to-back direction and is rotatably connected to the base frame, the transverse axis is arranged along the left-to-right direction and the middle part is connected to the middle part of the longitudinal axis, the gear shift bracket is located on the right side of the transverse axis and is rotatably connected to the base frame through a support shaft arranged along the left-to-right direction, the right end of the transverse axis is universally connected to the gear shift bracket, the base frame is located on the left side of the transverse axis and is provided with an elastic supporting member for supporting the left end of the transverse axis, and the gear lever is vertically connected to the upper side of the transverse axis.

[0006] In the above scheme, the longitudinal axis can rotate with the front-to-rear direction as the axis, so as to realize the swing of the gear lever in the left-to-right direction; the transverse axis can rotate with the left-to-right direction as the axis, so as to realize the swing of the gear lever in the front-to-rear direction; at the same time, since the gear shift bracket is rotatably connected to the base frame through a support shaft, when the gear lever swings in the left-to-right direction and causes the right end of the transverse axis to move up and down, the gear shift bracket can rotate and adjust accordingly due to the universal connection with the right end of the transverse axis to realize gear switching; and the elastic supporting member on the base frame can support the left end of the transverse axis to ensure the stability of the gear lever when switching; compared with the prior art, the above scheme adopts a "cross" design formed by the longitudinal axis combined with the transverse axis, thereby ensuring that the gear lever can only be switched in the front-to-rear direction and the left-to-right direction, avoiding the problem of switching deviation, and at the same time, stable switching of the gear lever is achieved through the shift bracket and the elastic supporting member, and the structure is reliable.

[0007] In an improved embodiment, the elastic supporting member includes a torsion spring steel wire, and a supporting shaft for the torsion spring steel wire to be sleeved is provided in front or rear of the position of the base frame located on the left side of the horizontal axis. The torsion spring steel wire has an upper wire end and a lower wire end. The upper wire end is bent downward and then extended laterally in the direction of the horizontal axis to form a lower support section, and the lower wire end is bent upward and then extended laterally in the direction of the horizontal axis to form an upper support section. The left end of the horizontal axis is clamped between the upper support section and the lower support section, thereby achieving effective support for the left end of the horizontal axis while ensuring that the left end of the horizontal axis can move or rotate.

[0008] In an improved embodiment, a rubber gasket is sleeved on the left end of the horizontal axis, and an annular positioning groove is provided on the outer peripheral wall of the rubber gasket. The upper support section and the lower support section are respectively connected to the upper and lower sides of the annular positioning groove, thereby improving the support stability of the left end of the horizontal axis by the elastic supporting part through the provision of the rubber gasket.

[0009] In an improved embodiment, the elastic supporting member also includes a limit block, which is connected to the base frame and located between the supporting axis and the horizontal axis, and the upper side of the limit block is provided with an upper limit groove for the upper supporting section to be embedded, and the lower side of the limit block is provided with a lower limit groove for the lower supporting section to be embedded, thereby ensuring the position of the upper supporting section and the lower supporting section by the setting of the limit block.

[0010] In an improved implementation, a ball head structure is provided at the right end of the transverse axis, and a mounting groove for the ball head structure to flexibly cooperate is provided on the side of the shift bracket facing the transverse axis, thereby realizing a universal connection between the right end of the transverse axis and the shift bracket.

[0011] In an improved implementation, an annular avoidance groove is provided on the transverse axis at a position adjacent to the ball head structure, and the avoidance groove is provided to avoid interference between the transverse axis and the shift bracket.

[0012] In an improved implementation scheme, a left mounting frame and a right mounting frame are respectively provided on the left and right sides of the lower part of the gear handle, the left mounting frame is fixedly connected to the left part of the transverse axis, and the right mounting frame is fixedly connected to the right part of the transverse axis, thereby improving the connection stability between the gear handle and the transverse axis.
