The shift lever assembly 200 comprises a shift lever 210, the shift lever 210 is rotatably connected with the housing 100, a first end of the shift lever 210 is provided with a weight reduction portion 211, the weight reduction portion 211 extends out of the accommodating cavity 101, a second end of the shift lever 210 is arranged in the accommodating cavity 101, and the second end of the shift lever 210 is matched with the contact switch 300 so as to control the on-off of the contact switch 300 when the shift lever 210 rotates, so that the inertia force of the shift lever 210 in the driving process of a vehicle is reduced, the switching state of a switching device is prevented from being changed under the condition that a driver does not operate the switching device, and the stability of the switching device is improved.

It will be appreciated that the receiving cavity 101 has an opening through which a first end of the lever 210 extends for easy manipulation by a user, and the opening of the receiving cavity 101 may be provided with a rotating shaft 102, such as a connecting pin, and the lever 210 may be provided with an opening through which the connecting pin may be inserted into the opening of the lever 210 during assembly, such that the lever 210 may rotate about the connecting pin between the first end and the second end of the lever 210.

Illustratively, when the user dials the dial 210, the weight reduction portion 211 may be held, and when the first end of the dial 210 is dialed up, i.e., rotated counterclockwise, the second end of the dial 210 rotates downward in the accommodating cavity 101 and may correspond to the on state of the tact switch 300, and when the user dials down the first end of the dial 210, i.e., rotated clockwise, the second end of the dial 210 rotates upward in the accommodating cavity 101 and may correspond to the off state of the tact switch 300.

It should be noted that the switch device may be installed on a steering wheel of an automobile as a module, or may also be installed on a console of an automobile as a module, which is not specifically limited in this embodiment of the present application.

First, the specific structure of the lever assembly 200 and the control method of the touch switch by the lever 210 will be described in detail.

Because in the course of driving of car jolt or vibration, the erroneous rotation of driving lever 210 mainly produces under the effect of inertial force, in order to avoid this condition, can design the form of the different parts of driving lever 210, for example, can reduce the inertial force of driving lever 210 through the design of the structure and the selection of material to driving lever 210, or, through improving the drive power that drives driving lever 210 and rotate, make driving lever 210 be difficult to shake under the effect of inertia, or, can change the stroke that driving lever 210 controls contact switch 300 break-make, make driving lever 210 rotate even under the effect of inertia and also can not change contact switch 300's on-off state easily.

With reference to fig. 1 and fig. 2, in a possible implementation manner, the weight reduction portion 211 may be a weight reduction handle, the weight reduction handle extends out of the accommodating cavity 101, and at least one of a hollow structure or a light section is disposed on the weight reduction handle, wherein the hollow structure includes at least one weight reduction hole, and the light section may reduce the density of the weight reduction handle, so that the density of the weight reduction handle is lower than the second end of the shift lever 210, thereby reducing the weight of the shift lever 210, so as to reduce the inertia force of the shift lever 210 when the vehicle bumps or vibrates, and avoid the misoperation caused by shaking.

It is understood that the weight-reduction handle may be an operating part of a user while driving a vehicle, that is, the weight-reduction handle may be operated by being held to control the rotation of the lever 210.

For example, the weight reduction handle may be rod-shaped, the weight reduction hole may be a center of the weight reduction handle, and a hole extending along a length direction of the weight reduction handle, that is, the weight reduction handle may be a cylindrical hollow structure.

In addition, in order to reduce the weight of the weight-reducing portion 211, the weight-reducing portion 211 may be made of a light material, including but not limited to a light plastic, a light metal, and the like, which is not particularly limited in the embodiments of the present application.

Since the two ends of the travel of the lever 210 correspond to the on and off states of the tact switch 300, in practical applications, in order to realize single or short-time on control of the lever 210 to the tact switch 300, the lever 210 needs to be reset after being shifted to the on state of the tact switch 300.

In a possible implementation manner, the lever assembly 200 may further include a top pillar 220 and an elastic member 230, the second end of the lever 210 is provided with a moving slot 212, the top pillar 220 may be inserted into the moving slot 212, and at least a portion of the top pillar 220 extends out of the moving slot 212 and abuts against an inner wall of the accommodating cavity 101, the elastic member 230 is located in the moving slot 212, and the elastic member 230 applies an elastic force to the top pillar 220 toward an outside of the moving slot 212.

It can be understood that, when the shift lever 210 is shifted to a specific position, a pre-tightening force can be generated by the elastic member 230, so that the top pillar 220 maintains a contact state with the inner wall of the accommodating groove, thereby preventing the shift lever 210 from shaking, and meanwhile, the elastic member 230 can provide an elastic force required for resetting when the shift lever 210 is shifted.

Illustratively, when the first end of the lever 210 is located at the lower side, the contact switch 300 is in the off state, and the lever 210 is moved counterclockwise, the top pillar 220 slides along the accommodating cavity 101 and overcomes the elastic force of the elastic member 230, and after the contact switch 300 is turned on, if the lever 210 is released, the lever 210 rotates clockwise to return to the initial state under the elastic force of the elastic member 230, and the contact switch 300 is turned off.

In some embodiments, the inner wall of the accommodating cavity 101 may be provided with an abutting surface 103, the abutting surface 103 is disposed obliquely with respect to the shift lever 210, one end of the top pillar 220 protruding from the moving groove 212 abuts against the abutting surface 103, when the shift lever 210 rotates, the top pillar 220 slides along the abutting surface 103, the top pillar 220 moves along the moving groove 212, when the top pillar 220 slides along the abutting surface 103, the top pillar 220 may compress the elastic member 230, and the moving top pillar 220 may avoid interference with the accommodating cavity 101, so as to improve the smoothness of sliding of the top pillar 220.

The specific arrangement of the elastic member 230 will be described in detail below.

With continued reference to fig. 1 and fig. 2, in a possible implementation manner, one end of the top pillar 220 inserted into the moving slot 212 has a receiving hole 221, a first end of the elastic member 230 is inserted into the receiving hole 221, and a second end of the elastic member 230 extends out of the receiving hole 221 and abuts against the bottom of the moving slot 212.

It can be understood that the elastic member 230 may be a spring, and the spring is compressed by the top pillar 220, and the compression and rebound directions of the elastic member 230 are consistent with the moving direction of the top pillar 220, so that the reliability of the moving setting of the top pillar 220 can be ensured, and the elastic member 230 is prevented from coming out or being stuck during the moving process of the top pillar 220.

In addition, the end of the top pillar 220 protruding from the moving groove 212 may be provided with a chamfer or a circular arc end to reduce the friction force between the top pillar 220 and the abutting surface 103, reduce the wear of the top pillar 220, and improve the service life of the switch device when the top pillar 220 abuts against and slides on the abutting surface 103.

It should be noted that, when the shift lever 210 is shifted from the off state to the on state, the elastic force of the elastic member 230 needs to be overcome, i.e., the magnitude of the shift force required to change the shift position of the shift lever 210 depends on the magnitude of the elastic force of the elastic member 230, and accordingly, the elastic force of the elastic member 230 needs to be overcome if the shift lever 210 rotates under the action of the inertia force in case of a bump or a vibration, so that the misoperation of the shift lever 210 due to the bump or the vibration can be avoided by adjusting the elastic force of the elastic member 230.

In some embodiments, the value of the elastic force of the elastic element 230 overcome by the rotation of the shift lever 210 may be 6.8N to 7.2N, i.e., the magnitude of the shift force of the shift lever 210 may be 6.8N to 7.2N, so as to ensure that the elastic force is large enough to keep the shift lever 210 stable when the shift lever 210 shakes during bumping or vibration, and at the same time, avoid the influence of the excessive shift force of the shift lever 210 caused by the elastic element 230 on the operation feel.

For example, the shift lever 210 needs a shift force of 6.8N, 6.9N, 7.20N, 7.1N, 7.2N, etc. when rotating, and the specific values in the embodiment of the present application are not limited.

The structure of the tact switch 300 and the engagement manner of the tact switch 300 with the lever 210 will be described in detail.

With continued reference to fig. 1 to 5, in one possible implementation manner, the contact switch 300 may include a toggle member 310, a slider 320, a movable contact piece 330 and a stationary contact piece 340, wherein the toggle member 310 is connected to the second end of the toggle member 210, the slider 320 is connected to the toggle member 310, the toggle member 210 rotates to drive the slider 320 to move, and the movable contact piece 330 is in contact with and separated from the stationary contact piece 340 through the movement of the slider 320.

It can be understood that when the movable contact piece 330 contacts with the static contact piece 340, the contact piece switch 300 is in a connected state, and when the movable contact piece 330 is separated from the static contact piece 340, the contact piece switch 300 is in a disconnected state, a sliding groove may be arranged in the accommodating cavity 101, the sliding block 320 is positioned in the sliding groove, the static contact piece 340 is positioned in the sliding groove, and the movable contact piece 330 is arranged on the sliding block 320, so that when the sliding block 320 moves along the sliding groove, the movable contact piece 330 contacts with or separates from the static contact piece 340, thus the linkage between the shift lever 210 and the contact piece switch 300 can be realized, and the on-off of the contact piece switch 300 is realized through the movement of the movable contact piece 330 relative to the static contact piece 340.

For example, the static contact 340 may have two contacts separated from each other, and when the movable contact 330 contacts the static contact 340, the two contacts of the static contact 340 may be conducted.

It should be noted that, in the embodiment of the present application, since the shift lever 210 is linked with the slider 320, when the shift lever 210 rotates, the shift member 310 is driven to move, so as to drive the slider 320 to move, a rotation stroke of the shift lever 210 corresponds to a movement stroke of the slider 320, that is, when the movable contact 330 and the stationary contact 340 at a certain position in the movement stroke of the slider 320 start to contact, a certain position of the rotation stroke of the shift lever 210 corresponds to the certain position.

It can be understood by those skilled in the art that when the automobile encounters a bump or a vibration and the shift lever 210 tends to move under the action of inertia force, the rotation angle of the shift lever 210 needs to reach a certain value, so that the shift lever 210 reaches the position where the movable contact 330 contacts the stationary contact 340, and a malfunction occurs, and therefore, the contact switch 300 can be prevented from being affected by the bump or the vibration by adjusting the position where the movable contact 330 contacts the stationary contact 340 during the stroke of the slider 320.

In some embodiments, when the movable contact piece 330 is separated from the fixed contact piece 340, the distance between the movable contact piece 330 and the fixed contact piece 340 is greater than one-half of the moving stroke of the slider 320, i.e., when the lever 210 rotates, the movable contact piece 330 and the fixed contact piece 340 will contact when the rotating angle exceeds the total rotating stroke.

For example, the rotational travel position of lever 210 may be defined as "initial position", "1/4 travel", "1/2 travel", "3/4 travel", "full travel", where contact switch 300 is open, corresponding to position a in fig. 5, the distance between the stationary contact 340 and the movable contact 330 is the largest, and when the lever 210 is rotated from the "initial position" to the "full stroke", the movable contact 330 is close to the fixed contact 340, and in the embodiment of the present application, the contact position between the movable contact 330 and the fixed contact 340 can be designed within the range from "1/2 stroke" to "3/4 stroke" of the toggle lever 210, for example, the position b in fig. 5, so that when the switch device is closed, even if the shift lever 210 is slightly shaken, the movable contact piece 330 and the static contact piece 340 are not contacted, so that the false opening is more effectively prevented, and the position c in the figure 5 can be corresponded when the full stroke is reached.

It should be noted that the rotation angle of the shift lever 210 from the "initial position" to the "full stroke" may be set according to the requirement of the actual application scenario, for example, the rotation angle of the shift lever 210 is 6 °, and the actual corresponding angle of the "1/2 stroke" is 3 °, but due to the angle lag in the actual application, the angle corresponding to the "1/2 stroke" in the theoretical design may be 2.5 °, that is, a lag amount of 0.5 ° is provided.
