[0038] The following will be combined with Figures 1 to 6 , to describe the embodiments of the present application.

[0039] According to an embodiment of the present application, on the one hand, a handle driving device is provided, including: a mounting base 1, a first transmission assembly 2, a second transmission assembly 3 and a lubricant. The first transmission assembly 2 includes a first transmission arm 201 and a protrusion 202. The first transmission arm 201 is cooperated with the handle body 5 and is swingably arranged on the mounting base 1. The protrusion 202 is arranged on the first transmission arm 201. The second transmission assembly 3 includes a second transmission arm 301 and a groove 302. The second transmission arm 301 is reciprocatingly arranged on the mounting base 1. The groove 302 is arranged on the second transmission arm 301 and is used to cooperate with the protrusion 202. The second transmission assembly 3 is adapted to reciprocate itself and drive the first transmission arm 201 to swing through the cooperation of the groove 302 and the protrusion 202. The lubricant is arranged in the groove 302 and is used to reduce the friction between the protrusion 202 and the groove 302.

[0040] Applying the handle driving device of this embodiment, a protrusion 202 is arranged on the first transmission arm 201, and a groove 302 is arranged on the second transmission arm 301. When the second transmission arm 301 drives the first transmission arm 201 to swing, mainly through the cooperation of the inner wall of the groove 302 and the outer wall of the protrusion 202, after applying the lubricant to the inner wall of the groove 302, the friction coefficient during the sliding cooperation between the protrusion 202 and the groove 302 can be effectively reduced, the wear condition during the contact friction between the protrusion 202 and the groove 302 can be effectively alleviated, the service life of the first transmission arm 201 and the second transmission arm 301 can be improved, and at the same time, abnormal noise generated during component friction can be avoided, effectively solving the problem that the transmission components of the existing handle are prone to wear and cause failures.

[0041] Among them, it should be noted that the mounting base 1 refers to the structure for mounting the first transmission component 2 and the second transmission component 3. The mounting base 1 can be an independent mounting base body or the door body of a vehicle door, and there is no strict limitation here.

[0042] In addition, it should be noted that the specific movement mode of the second transmission arm 301 is not limited. The second transmission arm 301 can reciprocate by swinging or rotating around a point, or can reciprocate linearly along a preset direction, as long as it can drive the first transmission arm 201 to move. It can be flexibly selected according to the layout requirements.

[0043] Specifically, the specific type of lubricant is not limited. It can be lubricating greases of various models or water-based lubricants, and can be flexibly selected according to requirements.

[0044] Furthermore, the protrusion 202 is provided on the outer wall of the first transmission arm 201, preferably on the outer wall of the first transmission arm 201 close to the second transmission arm 301, and the groove 302 is provided on the outer walls of the second transmission arm 301 and the corresponding protrusion 202.

[0045] In some embodiments of the present application, the moving track of the groove 302 corresponding to the protrusion 202 extends in a curve. The edge parts of the groove 302 in this form are all continuous curves. Compared with the form with a fold, the sliding process of the protrusion 202 can be made more continuous, and the stress concentration phenomenon on the wall surface of the groove 302 can be effectively reduced, and the service life of the groove 302 can be extended.

[0046] Specifically, as Figures 4 to 6 shown, the specific structures of the groove 302 and the protrusion 202 are not limited. The protrusion 202 can be columnar, hemispherical, etc., as long as it protrudes outward to meet the use requirements. The specific structure of the groove 302 can be matched according to the volume of the protrusion 202 and the movement envelope of the protrusion 202.

[0047] In some embodiments of the present application, the connection position between the side wall of the groove 302 and the outer wall of the second transmission arm 301 has a smooth transition, which can effectively reduce the stress concentration phenomenon at this position and also reduce the friction generated between this position and the protrusion 202.

[0048] Specifically, the specific manner of the smooth transition is not limited. It can be to chamfer the connection position between the side wall of the groove 302 and the outer wall of the second transmission arm 301, or to provide a structure with a curved surface protruding outward, and can be flexibly selected.

[0049] In some embodiments of the present application, during at least a part of the swinging process of the first transmission arm 201, the surface of the protrusion 202 cooperates with multiple positions on the inner wall of the groove 302. During at least a part of the swinging process of the first transmission arm 201, the surface of the protrusion 202 is in line contact with the inner wall of the groove 302. By increasing the contact area during the cooperation between the protrusion 202 and the groove 302, the forces received during the processes of the first transmission arm 201 and the second transmission arm 301 are dispersed to each contact position, so as to reduce the force at each contact position, thereby ensuring the lubrication effect of the lubricant and reducing the wear during the sliding fit of the components.

[0050] It can be understood that as an alternative embodiment, when the surface of the protrusion 202 slides and cooperates with the inner wall of the groove 302, it can also be a single point contact throughout the process.

[0051] Specifically, the function of the lubricant is to form a lubricant layer between the surface of the protrusion 202 and the inner wall of the groove 302 to reduce the friction coefficient during friction. However, when there is a point contact between a local position of the protrusion 202 and the wall surface of the groove 302 and the force is too large, the thickness of the lubricant layer formed by the lubricant will be squeezed to a thinner state, thereby reducing the lubrication effect of the lubricant.

[0052] In this embodiment, since the contact area during the cooperation between the protrusion 202 and the groove 302 is increased, the force at the contact position of a single sliding friction can be reduced, thereby ensuring the lubrication effect of the lubricant.

[0053] In some embodiments of the present application, the surface of the protrusion 202 is a continuous curved surface. This form of protrusion 202 has better force-bearing performance and can reduce the stress concentration phenomenon at the local part of the protrusion 202.

[0054] In some embodiments of the present application, the first transmission assembly 2 further includes a first rotating shaft 203. The first transmission arm 201 is swingably sleeved on the first transmission arm 201. The first rotating shaft 203 extends along the vehicle height direction. The second transmission assembly 3 further includes a second rotating shaft 303. The second transmission arm 301 is swingably sleeved on the second rotating shaft 303. The second rotating shaft 303 extends along the vehicle width direction. When the second transmission arm 301 of this movement form drives the first transmission arm 201, the occupied installation space is small, and the situation that the thickness of the vehicle door increases to match the movement mode of the second transmission arm 301 can be effectively avoided.

[0055] Among them, it should be noted that the vehicle height direction refers to Figure 1 the "height direction" indicated by the arrow in Figure 1 the vehicle length direction refers to the "length direction" indicated by the arrow in Figure 1The direction perpendicular to the "height direction" and "length direction" indicated by the arrow in the figure.

[0056] Specifically, as Figure 6 shown, a first shaft hole 204 for the first rotating shaft 203 to pass through is provided on the first transmission arm 201; as Figure 3 shown, a second shaft hole 305 for the second rotating shaft 303 to pass through is provided on the second transmission arm 301, as Figure 1 and Figure 2 shown, when Figure 1 the second transmission arm 301 in Figure 2 swings counterclockwise, it is the attitude of the second transmission arm 301 in

[0057] During this process, the second transmission arm 301 facilitates pushing the first transmission arm 201 to swing in the plane of the vehicle length direction and the vehicle width direction.

[0058] Furthermore, in order to enable the first transmission arm 201 to automatically return to its original position, an elastic member is also provided at the position where the first transmission arm 201 cooperates with the first shaft hole 204. When the second transmission arm 301 swings clockwise, the first transmission arm 201 can automatically return to its original position under the action of the elastic member.

[0059] Among them, the elastic member can also be an independent pushing structure capable of pushing the first transmission arm 201 back to its original position, which can be flexibly selected and will not be elaborated here too much.

[0060] In some embodiments of the present application, the handle driving device further includes a driving component 4 for driving the second transmission arm 301 to reciprocate. The driving component 4 is arranged on the mounting seat 1 and cooperates with the second transmission arm 301, with a simple and reliable structure and being convenient for processing and manufacturing.

[0061] Among them, the type of the driving component 4 is not limited. It can be a rotational driving structure such as a motor, or a reciprocating mobile driving structure in the form of a telescopic cylinder or a gear-rack combination, as long as it can drive the second transmission arm 301 to swing.

[0062] Specifically, as Figure 1 and Figure 2As shown, the perforation 304 extends in a curved shape as a whole, and the specification size of the perforation 304 only needs to correspond to and match the movement track of the threading part 403; in addition, the driving arm 401 extends in an arc shape, and the width of the driving arm 401 gradually increases in the direction from the threading part 403 towards the driving shaft 402. This form of the driving arm 401 has higher structural strength and is more durable and reliable.

[0063] In some embodiments of the present application, a number of first structural grooves are provided on the outer wall of the first transmission arm 201, and a number of second structural grooves are provided on the outer wall of the second transmission arm 301. This form of the first transmission arm 201 and the second transmission arm 301 are lighter in weight and stronger in bending resistance.

[0064] Among them, the specific specification sizes and quantities of the first structural grooves and the second structural grooves are not limited, and can be flexibly selected according to the specific shapes of the first transmission arm 201 and the second transmission arm 301.

The handle driving device is arranged on the door body, and the handle main body 5 is swingably arranged on the mounting seat 1 of the handle driving device, and the handle main body 5 cooperates with the first transmission arm 201 of the handle driving device.
