Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to a door handle, a vehicle door and a vehicle. Background Art

[0002] With the rapid development of the automobile industry and the increase in the number of cars, the number of traffic accidents and the number of casualties have increased significantly. How to maximize the protection of passenger safety and reduce the losses caused by traffic accidents is a problem that the transportation department and vehicle manufacturers are thinking about and trying to solve.

[0003] In traffic accidents, collisions can usually be divided into frontal collisions, side collisions and rear collisions. Among them, side collisions are the most dangerous because there is not enough space between the passengers and the door to produce large deformation to resist the collision force. There are two main forms of injury to passengers in side collisions: one is that the door is severely deformed and invades the passenger compartment, causing direct injuries; the other is that the door is severely deformed and triggers the door handle outward opening link, causing the door to open, or the door handle is thrown outward under the action of inertia, causing the door to open, causing the passenger to be thrown out of the passenger compartment during the vehicle rollover, causing indirect injuries.

[0048] like Figure 1 and Figure 2 As shown, some embodiments of the present application provide a door handle applied to a vehicle door, for preventing the vehicle door from opening abnormally when the vehicle door is subjected to external impact, thereby ensuring the safety of users in the vehicle.

[0049] The door handle includes a base 100 , a handle 200 , an unlocking arm 300 and an inertia block 400 .

[0050] It should be noted that the base 100 is used to connect with the vehicle door so as to install the door handle on the vehicle door. Specifically, a clearance groove is provided on one side of the base 100, and the handle 200 is partially accommodated in the clearance groove, and the handle 200 is rotatably connected to the base 100, so that the user can unlock the vehicle door in the process of rotating the handle 200, thereby opening the vehicle door.

[0051] In addition, the unlocking arm 300 is arranged at one end of the base 100 away from the handle 200, and one end of the unlocking arm 300 is rotatably connected to the base 100, that is, the unlocking arm 300 can rotate relative to the base 100, and the other end of the unlocking arm 300 is connected to the handle 200, so that when the handle 200 rotates relative to the base 100, it can drive the unlocking arm 300 to rotate synchronously, thereby unlocking the vehicle door by the unlocking arm 300 during the rotation process.

[0052] It should be noted that, in this embodiment, the unlocking arm 300 is used to connect with the door lock mechanism. When the user pulls the handle 200 to a preset position, the unlocking arm 300 rotates synchronously with the handle 200, and the door lock mechanism is driven to move to the preset position through the unlocking arm 300, and the door is unlocked, thereby realizing the door opening. When the external force applied by the user to the handle 200 is cancelled, the door lock mechanism returns to the initial state.

[0053] The inertia block 400 is movably arranged on a side of the base 100 away from the handle 200 , and the inertia block 400 is rotationally connected to the base 100 , and the inertia block 400 is close to the unlocking arm 300 , and the inertia block 400 has a first state and a second state relative to the base 100 .

[0054] Specifically, when the inertia block 400 is in the first state, one end of the inertia block 400 overlaps the unlocking arm 300 to form a limiting connection structure, so that the unlocking arm 300 is limited by the inertia block 400 to limit the rotation of the unlocking arm 300 and the handle 200. It can be understood that at this time, when an external force acts on the handle 200, since the inertia block 400 is connected with the unlocking arm 300 to form a limiting structure, the unlocking arm 300 maintains a stable state under the action of the inertia block 400; since the unlocking arm 300 is connected with the handle 200, the unlocking arm 300 is limited by the unlocking arm 300 to prevent the handle 200 from rotating, thereby preventing the door from opening abnormally.

[0055] It should be noted that when the door handle is hit by external force, the inertia block 400 rotates to the first state relative to the base 100 under the action of the external force impact, so that the end of the inertia block 400 close to the unlocking arm 300 overlaps with the unlocking arm 300 to form a limiting connection structure, thereby preventing the door handle from opening abnormally.

[0056] Furthermore, when the inertia block 400 is in the second state, the inertia block 400 is separated from the unlocking arm 300, and at this time, there is a gap between the inertia block 400 and the unlocking arm 300, so as to release the restriction on the rotation of the unlocking arm 300 and the handle 200. That is to say, at this time, the user can rotate the handle 200, thereby driving the unlocking arm 300 to rotate synchronously, and the unlocking arm 300 drives the door lock mechanism to move to a preset position, and the door is opened.

[0057] It is understandable that when the inertia block 400 is in the second state, that is, the impact force acting on the door handle disappears, at this time, the inertia block 400 recovers from the first state to the second state, that is, the limit on the unlocking arm 300 is released by the inertia block 400, thereby ensuring that the door handle can be opened normally.

[0058] The door handle provided by the present application is provided with an unlocking arm 300 and an inertia block 400 movably disposed on a side of the base 100 away from the handle 200, so that the handle 200 can drive the unlocking arm 300 to rotate synchronously when it rotates, thereby connecting with the door lock mechanism on the vehicle door through the unlocking arm 300, and driving the door lock mechanism to move to a preset position, so as to realize normal opening of the vehicle door; by forming a limiting structure with the inertia block 400 and the unlocking arm 300, so that when the vehicle door is impacted by an external force, the inertia block 400 rotates to the first state under the action of the external force impact, and forms a limiting structure with the unlocking arm 300, so as to avoid abnormal opening of the handle 200, thereby effectively protecting the life safety of the user in the vehicle; when the impact force acting on the door handle is cancelled, the inertia block 400 recovers from the first state to the second state, that is, there is a gap between the inertia block 400 and the unlocking arm 300, so as to release the restriction on the unlocking arm 300, so that the user can open the vehicle door normally.

[0059] It is understood that in this embodiment, the first state refers to the state of the inertia block 400 when the door handle is impacted or hit by an external force. The second state refers to the state of the inertia block 400 when the impact force or impact force acting on the door handle is cancelled, that is, when the door handle is not impacted or hit by an external force.

[0060] Specifically, when the door handle is not impacted or hit by external force, the inertia block 400 is in the second state under the action of its own gravity; when the door handle is impacted or hit by external force, the inertia block 400 rotates to the first state under the action of the impact or hit of the external force, and when the impact force or hit force is removed, the inertia block 400 recovers from the first state to the second state under the action of its own gravity.

[0061] like Figure 2 , Figure 5 and Figure 6As shown, in some embodiments of the present application, the unlocking arm 300 includes a connecting block 310 and a connecting rod 320 .

[0062] The connection method between the connection block 310 and the connection rod 320 includes at least one of threaded connection, bolt connection, clamping, bonding, and integral molding, which can be specifically set according to actual conditions.

[0063] In this embodiment, the connecting block 310 and the connecting rod 320 are integrally formed and connected to improve the strength and stability of the overall structure of the unlocking arm 300 .

[0064] It should be noted that, in some other embodiments, a limiting structure (not shown in the figure) is provided on the base 100. When the inertia block 400 is in the first state, the limiting structure provides a limiting effect on the inertia block 400 to prevent the movement of the inertia block 400 from exceeding the first state, thereby ensuring that in the first state, the inertia block 400 can buckle the connecting block 310, thereby ensuring the stability of the buckling between the inertia block 400 and the connecting block 310.

[0065] Specifically, the connecting rod 320 is disposed at one end of the connecting block 310 , the axial direction of the connecting rod 320 is parallel to the thickness direction of the connecting block 310 , and the connecting rod 320 is rotatably connected to the base 100 .

[0066] It can be understood that the connecting block 310 rotates around the axis of the connecting rod 320 .

[0067] In addition, a curved burr 311 is provided on a side of the connection block 310 away from the inertia block 400, and the curved burr 311 is smoothly connected to the connection block 310, so that the unlocking arm 300 can be driven to rotate smoothly during the rotation of the handle 200 relative to the base 100, thereby improving the smoothness of the rotation of the unlocking arm 300 relative to the base 100, and improving the smoothness of the synchronous rotation of the unlocking arm 300 relative to the handle 200. Since the unlocking arm 300 is used to connect with the door lock mechanism of the vehicle door, the smoothness of the movement of the door lock mechanism is improved, thereby ensuring the smoothness of the door opening.

[0068] Furthermore, a protrusion 312 is provided on one side of the connection block 310 facing the inertia block 400. When the inertia block 400 is in the first state, the protrusion 312 is connected to the inertia block 400 to form a limiting structure to prevent the unlocking arm 300 and the handle 200 from rotating relative to the base 100, thereby forming a locking structure for the handle 200; when the inertia block 400 is in the second state, there is a gap between the protrusion 312 and the inertia block 400 to release the lock on the handle 200.

[0069] Furthermore, a limiting portion 313 is provided at one end of the arc-shaped burr 311 away from the connecting rod 320, so as to limit the handle 200 through the limiting portion 313 to avoid separation between the handle 200 and the unlocking arm 300, thereby ensuring the stability of the connection between the handle 200 and the unlocking arm 300.

[0070] like Figure 2 As shown, in some embodiments of the present application, a convex portion 210 is provided on one side of the handle 200 close to the arc-shaped burr 311 .

[0071] Among them, the arc-shaped burr 311 has a convex surface and a concave surface, and the convex portion 210 is slidably connected to the convex surface of the arc-shaped burr 311, that is, the side wall of the convex portion 210 abuts against the convex surface of the arc-shaped burr 311, and the side wall of the convex portion 210 is slidably connected to the convex surface of the arc-shaped burr 311, so that during the rotation of the handle 200 relative to the base 100, the convex portion 210 can be driven to rotate, and the arc-shaped burr 311 can be driven to rotate through the convex portion 210. Since the convex portion 210 is slidably connected to the convex surface of the arc-shaped burr 311, that is, the convex portion 210 can slide along the arc-shaped burr 311, so as to improve the smoothness and fluency of the unlocking arm 300 relative to the rotation of the base 100.

[0072] Furthermore, there is a gap between the side of the protrusion 210 facing the unlocking arm 300 and the unlocking arm 300 to avoid friction between the side of the unlocking arm 300 facing the protrusion 210 during the rotation of the protrusion 210 relative to the unlocking arm 300, thereby improving the smoothness of the rotation of the unlocking arm 300.

[0073] In addition, the convex portion 210 is limited by the limiting portion 313 to prevent the handle 200 and the unlocking arm 300 from being separated, thereby ensuring the stability of the sliding connection between the unlocking arm 300 and the handle 200 and improving the rotation stability of the unlocking arm 300 and the handle 200.

[0074] like Figure 2 and Figure 4 As shown, in some embodiments of the present application, the inertia block 400 includes a limiting rod 410 , a first connecting arm 420 and a second connecting arm 430 .

[0075] The first connecting arm 420 and the second connecting arm 430 are respectively arranged at two opposite sides of the limiting rod 410 along the axial direction perpendicular to the limiting rod 410. The connection between the first connecting arm 420 and the second connecting arm 430 and the limiting rod 410 includes any one of bolt connection, clamping, bonding or integral molding, which can be specifically set according to actual conditions.

[0076] Specifically, one end of the first connecting arm 420 in the length direction is connected to the limiting rod 410, and the other end of the first connecting arm 420 in the length direction is toward the side of the limiting rod 410 away from the second connecting arm 430; one end of the second connecting arm 430 in the length direction is connected to the limiting rod 410, and the other end of the second connecting arm 430 in the length direction is toward the side of the limiting rod 410 away from the first connecting arm 420.

[0077] In this embodiment, the first connecting arm 420 , the second connecting arm 430 and the limiting rod 410 are integrally formed and connected to improve the overall strength of the inertia block 400 .

[0078] Among them, the end of the first connecting arm 420 facing away from the second connecting arm 430 is provided with a flange 421 facing the unlocking arm 300, so as to define a groove 422 with a notch on the side of the first connecting arm 420 facing the protrusion 312, so that the protrusion 312 can be received in the groove 422 through the notch, thereby forming a limiting overlap structure with the protrusion 312, and thus forming a limiting connection structure with the unlocking arm 300 through the inertia block 400, so as to prevent the door handle from opening abnormally under the impact of external force.

[0079] Specifically, when the inertia block 400 is in the first state, the inner wall of the flange 421 abuts against the side wall of the protrusion 312 to form a limiting overlap structure, that is, the flange 421 is arranged around a part of the outer periphery of the protrusion 312, and the protrusion 312 is limited by the flange 421 to prevent the protrusion 312 from rotating relative to the base 100, thereby limiting the rotation of the unlocking arm 300 relative to the base 100 through the inertia block 400.

[0080] In addition, when the inertia block 400 is in the second state, there is a gap between the flange 421 and the protrusion 312, and at this time, the flange 421 has no limit effect on the protrusion 312, that is, the inertia block 400 releases the limit on the unlocking arm 300 through the inertia block 400. In other words, at this time, the unlocking arm 300 can rotate relative to the base 100 driven by the handle 200.

[0081] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a first card slot 110 and a second card slot 120 are provided on the side of the base 100 facing away from the handle 200, and the notch of the first card slot 110 faces the notch of the second card slot 120, and the first card slot 110 and the second card slot 120 are both cylindrical card slots, and the axis of the first card slot 110 coincides with the axis of the second card slot 120, and the caliber of the first card slot 110 is equal to the caliber of the second card slot 120.

[0082] Specifically, one end portion of the connecting rod 320 is received in the first slot 110, and the outer wall of the end of the connecting rod 320 close to the first slot 110 is in sliding contact with the inner wall of the first slot 110, so as to limit the end of the connecting rod 320 close to the first slot 110 through the inner wall of the first slot 110, so as to improve the stability of the connection between the connecting rod 320 and the first slot 110.

[0083] In addition, the other end portion of the connecting rod 320 is accommodated in the second slot 120, and the outer wall of the end of the connecting rod 320 close to the second slot 120 is in sliding contact with the inner wall of the second slot 120, so as to limit the end of the connecting rod 320 close to the second slot 120 through the inner wall of the second slot 120, so as to improve the stability of the connection between the connecting rod 320 and the second slot 120.

[0084] It should be noted that the side of the connecting rod 320 facing away from the second slot 120 contacts the bottom of the first slot 110, and the side of the connecting rod 320 facing away from the first slot 110 contacts the bottom of the second slot 120, so as to limit the connecting rod 320 through the bottom of the first slot 110 and the bottom of the second slot 120, thereby preventing the connecting rod 320 from shaking in the first slot 110 and the second slot 120, so as to improve the stability of the connection between the connecting rod 320 and the base 100.

[0085] By smoothly connecting one end of the connecting rod 320 to the inner wall of the first slot 110 and smoothly connecting the other end of the connecting rod 320 to the inner wall of the second slot 120, the friction between the connecting rod 320 and the inner wall of the first slot 110 and the friction between the connecting rod 320 and the inner wall of the second slot 120 can be reduced, thereby improving the smoothness of the rotation of the connecting rod 320 relative to the base 100, that is, improving the smoothness of the rotation of the unlocking arm 300 relative to the base 100.

[0086] like Figure 4 As shown, in some embodiments of the present application, a first annular step 411 is provided at one end of the limiting rod 410 in the axial direction to define a first column 412, the axis of the first column 412 coincides with the axis of the limiting rod 410, and the outer diameter of the first column 412 is smaller than the outer diameter of the limiting rod 410.

[0087] In addition, a second annular step 413 is provided at the other end of the limiting rod 410 in the axial direction to define a second column 414 , the axis of the second column 414 coincides with the axis of the limiting rod 410 , and the outer diameter of the second column 414 is smaller than the outer diameter of the limiting rod 410 .

[0088] In this embodiment, the axis of the first column 412 coincides with the axis of the second column 414 , and the outer diameter of the first column 412 is equal to the outer diameter of the second column 414 .

[0089] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, a first limiting rib 500 and a second limiting rib 600 which are arranged opposite to each other are provided on a side of the base 100 which is away from the handle 200 .

[0090] In this embodiment, the first limiting rib 500 and the second limiting rib 600 are both in the shape of a flat plate, and the first limiting rib 500 and the second limiting rib 600 are parallel to each other.

[0091] Among them, the first limiting rib 500 is provided with a first mounting hole 510, which penetrates the first limiting rib 500 along the thickness direction of the first limiting rib 500; the second limiting rib 600 is provided with a second mounting hole 610, which penetrates the second limiting rib 600 along the thickness direction of the second limiting rib 600.

[0092] Specifically, the axis of the first mounting hole 510 coincides with the axis of the second mounting hole 610 , and the aperture of the first mounting hole 510 is equal to the aperture of the second mounting hole 610 .

[0093] In some embodiments of the present application, one end of the first column 412 facing away from the second column 414 is passed through the first mounting hole 510, and the first annular step 411 is in contact with the side of the first limiting rib 500 facing the second limiting rib 600, and the outer wall of the first column 412 is in contact with the hole wall of the first mounting hole 510 to form a limiting effect on the first column 412 through the first mounting hole 510 to enhance the stability of the first column 412 in the first mounting hole 510.

[0094] In addition, one end of the second column 414 facing away from the first column 412 is passed through the second mounting hole 610, and the second annular step 413 is in smooth contact with the side of the second limiting rib 600 facing the first limiting rib 500, and the outer wall of the second column 414 is in smooth contact with the hole wall of the second mounting hole 610, so as to form a limiting effect on the second column 414 through the second mounting hole 610, so as to improve the stability of the second column 414 in the second mounting hole 610.

[0095] It can be understood that since the first limiting rib 500 contacts the first annular step 411 on the side facing the second limiting rib 600, and the second limiting rib 600 contacts the second annular step 413 on the side facing the first limiting rib 500, a limiting structure is formed for the limiting rod 410 through the first limiting rib 500 and the second limiting rib 600, so as to prevent the limiting rod 410 from shaking between the first limiting rib 500 and the second limiting rib 600, so as to improve the stability of the first limiting rib 500 and the second limiting rib 600 respectively connected to the limiting rod 410, thereby improving the stability of the first limiting rib 500 and the second limiting rib 600 respectively connected to the inertia block 400.

[0096] Since the first limiting rib 500 and the second limiting rib 600 are in smooth contact with the limiting rod 410 respectively, the smoothness of the rotation of the limiting rod 410 relative to the first limiting rib 500 and the second limiting rib 600 is improved, thereby improving the smoothness of the rotation of the inertia block 400 relative to the base 100, and improving the smoothness of the switching of the inertia block 400 between the first state and the second state, thereby ensuring the sensitivity of the inertia block 400 to the door handle limit.

[0097] Some embodiments of the present application also provide a vehicle door, comprising the door handle described in any one of the above embodiments.

[0098] Among them, the vehicle door has the structure and beneficial effects of the door handle described in any of the above embodiments, which will not be repeated here one by one.
