[0002] This application claims priority to Chinese Patent Application No. 2024218266704, filed on July 30, 2024, entitled "A Door Handle, a Car Door and a Vehicle", the entire contents of which are incorporated herein by reference, and to Chinese Patent Application No. 2024218267213, filed on July 30, 2024, entitled "A Door Handle, a Car Door and a Vehicle", parts of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of automotive parts technology, and more particularly to a door handle, a car door, and a vehicle. Background Technology

[0004] Currently, car door handles can be broadly categorized into concealed handles and non-concealed handles based on their installation location. Concealed retractable door handles require a separate space to accommodate the retraction of the handle. After the handle retracts, another space is created that is completely independent of the handle's retraction envelope. The structure for opening the car door is located within this space. When a person operates the corresponding mechanism within this space, the car door can be opened. In other words, this concealed retractable door handle solution requires two independent spaces, and this design must be electrically driven to retract the handle, resulting in a complex overall structure, high cost, and significant weight.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0065] As shown in Figures 1, 2 and 5, some embodiments of this application provide a door handle for use in vehicle doors to simplify the overall structure of the door handle and thereby reduce the production cost of the door handle.

[0066] The door handle includes a base 100, a handle 200, a first elastic element 300, an unlocking arm 400, a second elastic element 500, and a zipper 900. The first elastic element 300 and the second elastic element 500 can be either springs or torsion springs. Specifically, in this embodiment, the first elastic element 300 is a main torsion spring, and the second elastic element 500 is an unlocking arm torsion spring.

[0067] The base 100 has a relief groove 110 defined on one side in the thickness direction. It should be noted that, in this embodiment, the relief groove 110 is a wrist rest.

[0068] Furthermore, the handle 200 is rotatably connected to the base 100, meaning the handle 200 can rotate relative to the base 100. In this embodiment, the handle 200 is received in the relief groove 110 and partially covers the opening of the relief groove 110, meaning a portion of the relief groove 110 is not covered by the handle 200, thereby allowing the user to operate the handle 200 through the relief groove 110, thereby causing the handle 200 to rotate relative to the base 100.

[0069] Specifically, the side of the handle 200 away from the base 100 is flush with the groove of the clearance groove 110 to improve the aesthetics of the door handle.

[0070] In this embodiment, the handle 200 has a first state and a second state. The first state is the initial state of the handle 200, i.e., the state when the handle 200 is not subjected to external force. At this time, the handle 200 partially covers the opening of the relief groove 110, and the side of the handle 200 away from the base 100 is flush with the opening of the relief groove 110. The second state is the open state of the handle 200, i.e., the handle 200 rotates away from the base 100 under the action of external force. At this time, the handle 200 can open the vehicle door.

[0071] The first elastic element 300 is disposed on the side of the base 100 opposite to the handle 200. Specifically, the first elastic element 300 is disposed on the side of the base 100 opposite to the opening of the relief groove 110. The first elastic element 300 is elastically connected to the handle 200, and the first elastic element 300 has an elastic force on the handle 200, so that the handle 200 maintains a first state under the elastic force of the first elastic element 300.

[0072] In addition, when an external force is applied to the handle 200, causing the handle 200 to rotate from the first state to the second state, the first elastic element 300 stores elastic potential energy to provide elastic resistance to the handle 200. After the external force applied to the handle 200 is removed, the handle 200 is controlled to reset under the elastic force of the first elastic element 300, that is, the handle 200 is controlled to return from the second state to the first state.

[0073] The unlocking arm 400 is rotatably positioned on the side of the base 100 away from the handle 200. The unlocking arm 400 is connected to the handle 200 in a transmission manner, so that when the handle 200 rotates relative to the base 100, the unlocking arm 400 rotates relative to the base 100.

[0074] Specifically, the second elastic element 500 is elastically connected to the unlocking arm 400, and the second elastic element 500 exerts an elastic force on the unlocking arm 400 to keep the unlocking arm 400 in its initial state. It should be noted that when the handle 200 is in the first state, the unlocking arm 400 abuts against the handle 200, and at this time, the unlocking arm 400 is in its initial state, meaning that the unlocking arm 400 and the handle 200 maintain a relatively stable state. When the handle 200 rotates from the first state to the second state, the handle 200 drives the unlocking arm 400 to rotate to a preset position. Simultaneously, the second elastic element 500 stores elastic potential energy and exerts an elastic resistance on the unlocking arm 400, allowing the unlocking arm 400 to return to its initial state under the elastic resistance of the second elastic element 500. In addition, when the handle 200 returns to the first state from the second state, that is, the force exerted by the handle 200 on the unlocking arm 400 is removed, the unlocking arm 400 rotates to the initial state under the elastic force of the second elastic member 500, so as to control the reset of the unlocking arm 400 through the second elastic member 500.

[0075] In this embodiment, the initial state of the unlocking arm 400 refers to the state of the unlocking arm 400 relative to the handle 200 when the handle 200 is in the first state. At this time, the unlocking arm 400 abuts against the handle 200 and is in a relatively stationary state with the handle 200.

[0076] Additionally, the zipper 900 is located on the side of the base 100 away from the handle 200, and one end of the zipper 900 is connected to the unlocking arm 400 so that the zipper 900 can be pulled while the unlocking arm 400 rotates relative to the base 100. In this embodiment, the other end of the zipper 900 is used to connect to the door lock mechanism of the vehicle door so that the door lock mechanism of the vehicle door can be pulled by the unlocking arm 400 while the zipper 900 is pulled, thereby unlocking the vehicle door.

[0077] Specifically, when the handle 200 rotates from the first state to the second state under the action of an external force, the handle 200 drives the unlocking arm 400 to rotate synchronously. Simultaneously, the rotation of the unlocking arm 400 pulls the zipper 900, which in turn pulls the door lock mechanism, thus unlocking the door. When the external force on the handle 200 is removed, as the handle 200 returns from the second state to the first state under the elastic force of the first elastic element 300, the second elastic element 500 drives the unlocking arm 400 to return to its initial state. The unlocking arm 400 then pulls the zipper 900 back to its initial state, allowing the door to be unlocked again via the zipper 900.

[0078] The first elastic element 300 provides elastic resistance to the handle 200, allowing it to rotate from a first state to a second state under external force. The handle 200 then drives the unlocking arm 400 to rotate synchronously, pulling the zipper 900 to unlock the door. When the external force on the handle 200 is removed, it returns to the first state under the elastic force of the first elastic element 300, and the unlocking arm 400 returns to its initial state under the elastic force of the second elastic element 500. The unlocking arm 400 then drives the zipper 900 back to its initial state, allowing the door to be unlocked again. This application simplifies the overall structure of the door handle, improving production efficiency and reducing production costs.

[0079] As shown in FIG5, in some embodiments of this application, the handle 200 includes a body 210, a first drive arm 220 and a second drive arm 230, wherein the first drive arm 220 and the second drive arm 230 are disposed at intervals on the side of the body 210 facing the base 100.

[0080] In addition, the handle 200 also includes a handle cover 250, which is disposed on the side of the body 210 away from the first drive arm 220 and the second drive arm 230, and the connection between the handle cover 250 and the body 210 includes any one of bonding, snap-fit ​​connection or integral molding.

[0081] Specifically, in this embodiment, the handle cover 250 is installed on the body 210 by an internal snap fastener, that is, the handle cover 250 and the body 210 are snap-connected.

[0082] Specifically, one end of the first drive arm 220 and the second drive arm 230 is connected to the body 210, and the ends of the first drive arm 220 and the second drive arm 230 that are away from the body 210 are respectively inserted into the base 100 and rotatably connected to the side of the base 100 that is away from the body 210.

[0083] In this embodiment, the first drive arm 220 and the second drive arm 230 are respectively "L" shaped structures to improve the smoothness and stability of the handle 200 during rotation relative to the base 100 and to avoid collision between the handle 200 and the base 100.

[0084] It should be noted that the main body 210 has a clearance space on the side opposite to the first drive arm 220 and the second drive arm 230, so that the user's hand can be inserted into the clearance space through the clearance groove 110 to facilitate the operation of the handle 200.

[0085] The first drive arm 220 has a protrusion 240 on the side facing the second drive arm 230, so that the protrusion 240 abuts against the unlocking arm 400, thereby causing the handle 200 to rotate under the action of external force, and the protrusion 240 to push the unlocking arm 400 to rotate synchronously.

[0086] As shown in Figures 3 and 4, in some embodiments of this application, the base 100 has a first mounting hole 120 and a second mounting hole 130 disposed opposite to each other on the side away from the body 210. The diameter of the first mounting hole 120 is equal to the diameter of the second mounting hole 130, the axis of the first mounting hole 120 coincides with the axis of the second mounting hole 130, and both the first mounting hole 120 and the second mounting hole 130 are blind holes.

[0087] As shown in Figures 2 and 5, in some embodiments of this application, the first elastic element 300 includes a first torsion spring 310, a support rod 320, and a bushing 330. It should be noted that in this embodiment, the first torsion spring 310 is a main torsion spring, the support rod 320 is a main pin, and the bushing 330 is a through pin.

[0088] One end of the support rod 320 passes through the end of the first drive arm 220 opposite to the body 210 and is inserted into the first mounting hole 120. It can be understood that the axis of the support rod 320 coincides with the axis of the first mounting hole 120.

[0089] In this embodiment, one end of the support rod 320 near the first drive arm 220 abuts against the inner wall of the first mounting hole 120 to improve the stability of the connection between the support rod 320 and the hole wall of the first mounting hole 120.

[0090] In addition, the end of the support rod 320 away from the first drive arm 220 passes through the end of the second drive arm 230 away from the body 210 and is inserted into the second mounting hole 130. It can be understood that the axis of the support rod 320 coincides with the axis of the second mounting hole 130.

[0091] In this embodiment, one end of the second connecting rod 420 near the second driving arm 230 abuts against the inner wall of the second mounting hole 130 to improve the stability of the connection between the second connecting rod 420 and the hole wall of the second mounting hole 130, so as to limit the support rod 320 through the first mounting hole 120 and the second mounting hole 130, thereby improving the stability of the connection between the support rod 320 and the base 100.

[0092] Furthermore, the bushing 330 is sleeved on the support rod 320 and positioned between the first drive arm 220 and the second drive arm 230 to provide a limiting effect on the bushing 330, thereby improving the stability of the bushing 330 between the first drive arm 220 and the second drive arm 230. The bushing 330 is rotatably connected to the support rod 320, allowing the bushing 330 to rotate relative to the support rod 320.

[0093] Additionally, the first torsion spring 310 is sleeved on the bushing 330. It should be noted that the first torsion spring 310 includes a first torsion spring arm 311 and a second torsion spring arm 312, wherein the elastic forces of the first torsion spring arm 311 and the second torsion spring arm 312 are opposite. For example, if the elastic force of the first torsion spring arm 311 acts clockwise, the elastic force of the second torsion spring arm 312 acts counterclockwise; if the elastic force of the first torsion spring arm 311 acts counterclockwise, the elastic force of the second torsion spring arm 312 acts clockwise.

[0094] Specifically, the first torsion spring arm 311 abuts against the base 100, and the second torsion spring arm 312 abuts against the first drive arm 220 and the second drive arm 230, so as to provide elastic resistance to the first drive arm 220 and the second drive arm 230 through the second torsion spring arm 312, thereby ensuring that the handle 200 can be stably in the first state.

[0095] When the handle 200 rotates from the first state to the second state under the action of an external force, the first drive arm 220 and the second drive arm 230 respectively squeeze the second torsion spring arm 312, causing the second torsion spring arm 312 to bend and store elastic potential energy. This causes the second torsion spring arm 312 to apply elastic force to the first drive arm 220 and the second drive arm 230. After the external force acting on the handle 200 is removed, the first drive arm 220 and the second drive arm 230 return to their initial state under the elastic force of the second torsion spring arm 312, thereby driving the handle 200 to rotate from the second state to the first state, thus ensuring the stability of the handle 200 in the first state.

[0096] In addition, in some embodiments, the base 100 is provided with a rib 140 on the side facing the first elastic member 300. The rib 140 is spaced from the bushing 330, and the first torsion spring arm 311 is sleeved on the rib 140 so that the rib 140 can limit the first torsion spring arm 311, thereby improving the stability of the first torsion spring 310 between the first drive arm 220 and the second drive arm 230, and improving the stability of the connection between the first elastic member 300 and the base 100.

[0097] As shown in Figures 6 and 7, in some embodiments of this application, the unlocking arm 400 includes a connecting block 410 and a connecting rod 420.

[0098] The connection method between the connecting block 410 and the connecting rod 420 includes at least one of the following: threaded connection, bolted connection, snap-fit, adhesive, and integral molding, which can be specifically set according to the actual situation.

[0099] In this embodiment, the connecting block 410 and the connecting rod 420 are integrally formed and connected to improve the strength and stability of the overall structure of the unlocking arm 400.

[0100] Specifically, the connecting rod 420 is disposed at one end of the connecting block 410. The axial direction of the connecting rod 420 is parallel to the thickness direction of the connecting block 410, and the connecting rod 420 is rotatably connected to the base 100.

[0101] Understandably, the connecting block 410 rotates about the axis of the connecting rod 420.

[0102] Additionally, the connecting block 410 has an arc-shaped burr 411 on the side facing the first drive arm 220. The arc-shaped burr 411 is smoothly connected to the connecting block 410, so that the handle 200 can drive the unlocking arm 400 to rotate smoothly during the rotation of the handle 200 relative to the base 100, thereby improving the smoothness of the unlocking arm 400's rotation relative to the base 100 and the smoothness of the unlocking arm 400's synchronous rotation relative to the handle 200. Since the unlocking arm 400 is used to connect with the door lock mechanism of the vehicle door, it improves the smoothness of the door lock mechanism's movement, thereby ensuring the smoothness of the door opening.

[0103] In this embodiment, the connecting block 410 is provided with a slot 413 on the side away from the arc-shaped flash 411. The slot 413 is located at the end of the connecting block 410 away from the connecting rod 420. The slot opening of the slot 413 faces the second drive arm 230. The slot 413 is provided with a guide notch 414 on the side away from the connecting rod 420. The guide notch 414 is an "L" shaped notch.

[0104] As shown in Figures 2 to 4, in some embodiments, the base 100 has a snap-fit ​​portion 150 on the side opposite to the body 210, and the zipper 900 is snapped into the snap-fit ​​portion 150 to provide a limiting and fixing function for the zipper 900, thereby improving the stability of the connection between the zipper 900 and the base 100.

[0105] One end of the zipper 900 is housed in the slot 413, and the other end of the zipper 900 passes through the guide notch 414. The slot 413 and the guide notch 414 together limit the zipper 900, thereby improving the stability of the connection between the zipper 900 and the connecting block 410.

[0106] It should be noted that by providing a guide notch 414 on one side of the slot 413, the efficiency of connecting or disassembling the zipper 900 and the connecting block 410 is improved, so as to facilitate maintenance or replacement.

[0107] As shown in Figures 5 to 7, in some embodiments of this application, the arc-shaped burr 411 has a convex surface and a concave surface. The convex part 240 is slidably connected to the convex surface of the arc-shaped burr 411, that is, the sidewall of the convex part 240 abuts against the convex surface of the arc-shaped burr 411, and the sidewall of the convex part 240 is slidably connected to the convex surface of the arc-shaped burr 411, so that during the rotation of the handle 200 relative to the base 100, the convex part 240 can be driven to rotate by the first drive arm 220, and the convex part 240 abuts against the arc-shaped burr 411 and pushes the arc-shaped burr 411 to rotate. Since the convex part 240 is slidably connected to the convex surface of the arc-shaped burr 411, that is, the convex part 240 can slide along the arc-shaped burr 411, so as to improve the smoothness and fluidity of the unlocking arm 400 rotating relative to the base 100.

[0108] Furthermore, there is a gap between the side of the protrusion 240 facing the unlocking arm 400 and the unlocking arm 400 to avoid friction between the protrusion 240 and the side of the unlocking arm 400 facing the protrusion 240 during the rotation of the protrusion 240 relative to the unlocking arm 400, thereby improving the smoothness of the rotation of the unlocking arm 400.

[0109] In addition, a limiting part 412 is provided at the end of the arc-shaped burr 411 facing away from the connecting rod 420. The limiting part 412 limits the handle 200 to prevent the handle 200 from disengaging from the unlocking arm 400, thereby ensuring the stability of the connection between the handle 200 and the unlocking arm 400. Specifically, the limiting part 412 limits the protrusion 240 to prevent the handle 200 from disengaging from the unlocking arm 400, thereby ensuring the stability of the sliding connection between the unlocking arm 400 and the handle 200 and improving the stability of the rotation of the unlocking arm 400 and the handle 200.

[0110] As shown in Figures 2 and 5, in some embodiments of this application, the second elastic element 500 is sleeved on the connecting rod 420.

[0111] The second elastic element 500 includes a third torsion spring arm 510 and a fourth torsion spring arm 520. The third torsion spring arm 510 abuts against the base 100, and the fourth torsion spring arm 520 abuts against the connecting block 410. The second elastic element 500 provides an elastic limiting effect on the connecting block 410 to ensure that the connecting block 410 can return to its initial state under the elastic force of the second elastic element 500.

[0112] Specifically, when the handle 200 rotates from the first state to the second state under the action of an external force, the unlocking arm 400 rotates to a preset position under the push of the handle 200. At this time, the fourth torsion spring arm 520 bends under the pressure of the connecting block 410 and stores elastic potential energy. When the handle 200 rotates from the second state to the first state, the external force acting on the unlocking arm 400 is removed, so that the unlocking arm 400 returns to the initial state under the elastic force of the fourth torsion spring arm 520, thereby making the unlocking arm 400 abut against the first drive arm 220 to ensure that the handle 200 can push the unlocking arm 400 to rotate synchronously.

[0113] As shown in Figures 2 and 5, in some embodiments of this application, the door handle also includes an inertial block 600. The inertial block 600 is used to prevent the door from opening abnormally when it is hit by an external impact, thereby ensuring the safety of the user in the vehicle.

[0114] The inertial block 600 is movably disposed on the side of the base 100 away from the handle 200, and the inertial block 600 is rotatably connected to the base 100. The inertial block 600 is close to the unlocking arm 400, and the inertial block 600 has a first state and a second state relative to the base 100.

[0115] Specifically, in the first state, one end of the inertial block 600 overlaps with the unlocking arm 400 to form a limiting connection structure. This limits the unlocking arm 400, restricting its rotation and that of the handle 200. Understandably, when an external force is applied to the handle 200, the inertial block 600 maintains a stable state under its influence because of the limiting structure formed by the connection between the inertial block 600 and the unlocking arm 400. Furthermore, the unlocking arm 400 limits the handle 200, preventing its rotation and thus preventing abnormal opening of the door.

[0116] It should be noted that when the door handle is impacted by an external force, the inertial block 600 rotates relative to the base 100 to the first state under the impact of the external force, so that the end of the inertial block 600 near the unlocking arm 400 overlaps with the unlocking arm 400 to form a limiting connection structure, thereby preventing the door handle from opening abnormally.

[0117] Furthermore, when the inertial block 600 is in the second state, it separates from the unlocking arm 400. At this time, there is a gap between the inertial block 600 and the unlocking arm 400, thereby releasing the restriction on the rotation of the unlocking arm 400 and the handle 200. That is to say, at this time, the user can rotate the handle 200, thereby causing the unlocking arm 400 to rotate synchronously, and the unlocking arm 400 will drive the door lock mechanism to move to a preset position and open the door.

[0118] Understandably, when the inertial block 600 is in the second state, that is, when the impact force acting on the door handle disappears, the inertial block 600 returns from the first state to the second state. That is, the inertial block 600 releases the limit on the unlocking arm 400, thereby ensuring that the door handle can be opened normally.

[0119] The door handle provided in this application features an unlocking arm 400 and an inertial block 600 movably mounted on the side of the base 100 opposite to the handle 200. This allows the handle 200 to rotate synchronously with the unlocking arm 400, connecting it to the door lock mechanism and moving the lock mechanism to a preset position, thus enabling the door to open normally. By forming a limiting structure between the inertial block 600 and the unlocking arm 400, when the door is subjected to an external impact, the inertial block 600 rotates to a first state under the impact, forming a limiting structure with the unlocking arm 400, thereby preventing the handle 200 from opening abnormally and effectively protecting the safety of the user. When the impact force on the door handle is removed, the inertial block 600 returns from the first state to a second state, i.e., there is a gap between the inertial block 600 and the unlocking arm 400, releasing the restriction on the unlocking arm 400 and allowing the user to open the door normally.

[0120] It is understood that in this embodiment, the first state refers to the state of the inertial block 600 when the door handle is subjected to an external impact or collision. The second state refers to the state of the inertial block 600 when the impact or collision force acting on the door handle is removed, that is, when the door handle is not subjected to an external impact or collision.

[0121] Specifically, when the door handle is not subjected to external impact or impact, the inertial block 600 is in the second state under the action of its own gravity; when the door handle is subjected to external impact or impact, the inertial block 600 rotates to the first state under the action of the external impact or impact; when the impact or impact force is removed, the inertial block 600 returns to the second state from the first state under the action of its own gravity and the return spring 1000.

[0122] It should be noted that in this embodiment, the connecting block 410 has a protrusion 415 on the side facing the inertial block 600.

[0123] When the inertial block 600 is in the first state, the protrusion 415 is connected to the inertial block 600 to form a limiting structure to prevent the unlocking arm 400 and the handle 200 from rotating relative to the base 100, thereby forming a locking structure for the handle 200; when the inertial block 600 is in the second state, there is a gap between the protrusion 415 and the inertial block 600 to release the locking of the handle 200.

[0124] As shown in Figures 5 and 8, in some embodiments of this application, the inertial block 600 includes a limiting rod 610, a first connecting arm 620, and a second connecting arm 630.

[0125] Along the axis perpendicular to the limiting rod 610, the first connecting arm 620 and the second connecting arm 630 are respectively disposed on two opposite sides of the limiting rod 610. The connection method between the first connecting arm 620 and the limiting rod 610 and the limiting rod 610 includes any one of bolt connection, snap-fit, adhesive bonding or integral molding, which can be specifically set according to the actual situation.

[0126] Specifically, one end of the first connecting arm 620 along its length is connected to the limiting rod 610, and the other end of the first connecting arm 620 along its length faces the limiting rod 610 on the side away from the second connecting arm 630; one end of the second connecting arm 630 along its length is connected to the limiting rod 610, and the other end of the second connecting arm 630 along its length faces the limiting rod 610 on the side away from the first connecting arm 620.

[0127] In this embodiment, the first connecting arm 620, the second connecting arm 630, and the limiting rod 610 are integrally formed and connected to improve the overall strength of the inertial block 600.

[0128] The first connecting arm 620 has a flange 621 facing the unlocking arm 400 at one end away from the second connecting arm 630. This flange 621 defines a notched groove 622 on the side of the first connecting arm 620 facing the protrusion 415, so that the protrusion 415 can be received in the groove 622 through the notch. Thus, the flange 621 and the protrusion 415 form a limiting overlap structure, and the inertial block 600 and the unlocking arm 400 form a limiting connection structure to prevent the door handle from opening abnormally under the impact of external force.

[0129] Specifically, when the inertial block 600 is in the first state, the inner wall of the flange 621 abuts against the side wall of the protrusion 415 to form a limiting overlap structure. That is, the flange 621 surrounds a part of the outer periphery of the protrusion 415 and forms a limiting overlap on the protrusion 415 through the flange 621 to prevent the protrusion 415 from rotating relative to the base 100, thereby limiting the rotation of the unlocking arm 400 relative to the base 100 through the inertial block 600.

[0130] Furthermore, when the inertial block 600 is in the second state, there is a gap between the flange 621 and the protrusion 415. At this time, the flange 621 exerts an unlimited effect on the protrusion 415, that is, the inertial block 600 releases the restriction on the unlocking arm 400 through the inertial block 600. In other words, at this time, the unlocking arm 400 can rotate relative to the base 100 under the drive of the handle 200.

[0131] It should be noted that, as shown in Figures 2 and 5, in some embodiments of this application, the door handle also includes a return spring 1000. One end of the return spring 1000 is sleeved on the limiting rod 610, and the other end of the return spring 1000 abuts against the side of the second connecting arm 630 away from the base 100, so as to provide an elastic limiting force towards the base 100 to the second connecting arm 630 through the return spring 1000, so as to ensure the stability of the inertial block 600 on the base 100, so that when the door handle is in a stationary or uniform speed state, the inertial block 600 maintains the second state under the elastic force of the return spring 1000.

[0132] As shown in Figures 3 and 4, in some embodiments of this application, the base 100 has a first slot 160 and a second slot 170 disposed opposite to each other on the side away from the handle 200. The opening of the first slot 160 faces the opening of the second slot 170, and both the first slot 160 and the second slot 170 are cylindrical slots. The axis of the first slot 160 coincides with the axis of the second slot 170, and the diameter of the first slot 160 is equal to the diameter of the second slot 170.

[0133] Specifically, one end of the connecting rod 420 is housed in the first slot 160, and the outer wall of the end of the connecting rod 420 near the first slot 160 slides in contact with the inner wall of the first slot 160, so as to limit the end of the connecting rod 420 near the first slot 160 by the inner wall of the first slot 160, thereby improving the stability of the connection between the connecting rod 420 and the first slot 160.

[0134] In addition, the other end of the connecting rod 420 is received in the second slot 170, and the outer wall of the end of the connecting rod 420 near the second slot 170 slides in contact with the inner wall of the second slot 170, so as to limit the end of the connecting rod 420 near the second slot 170 by the inner wall of the second slot 170, thereby improving the stability of the connection between the connecting rod 420 and the second slot 170.

[0135] It should be noted that the side of the connecting rod 420 away from the second slot 170 contacts the bottom of the first slot 160, and the side of the connecting rod 420 away from the first slot 160 contacts the bottom of the second slot 170. This is to limit the connecting rod 420 by the bottom of the first slot 160 and the bottom of the second slot 170, preventing the connecting rod 420 from shaking in the first slot 160 and the second slot 170, thereby improving the stability of the connection between the connecting rod 420 and the base 100.

[0136] By smoothly connecting one end of the connecting rod 420 to the inner wall of the first slot 160 and the other end of the connecting rod 420 to the inner wall of the second slot 170, the friction between the connecting rod 420 and the inner wall of the first slot 160 and the inner wall of the second slot 170 is reduced, thereby improving the smoothness of the rotation of the connecting rod 420 relative to the base 100, that is, improving the smoothness of the rotation of the unlocking arm 400 relative to the base 100.

[0137] As shown in Figure 8, in some embodiments of this application, a first annular step 611 is provided at one end of the limiting rod 610 in the axial direction to define a first column 612. The axis of the first column 612 coincides with the axis of the limiting rod 610, and the outer diameter of the first column 612 is smaller than the outer diameter of the limiting rod 610.

[0138] In addition, a second annular step 613 is provided at the other end of the axial direction of the limiting rod 610 to define a second column 614. The axis of the second column 614 coincides with the axis of the limiting rod 610, and the outer diameter of the second column 614 is smaller than the outer diameter of the limiting rod 610.

[0139] In this embodiment, the axis of the first column 612 coincides with the axis of the second column 614, and the outer diameter of the first column 612 is equal to the outer diameter of the second column 614.

[0140] As shown in Figures 2 to 4, in some embodiments of this application, the base 100 is provided with a first limiting rib 700 and a second limiting rib 800 disposed opposite to each other on the side opposite to the handle 200.

[0141] In this embodiment, both the first limiting rib 700 and the second limiting rib 800 are flat, and the first limiting rib 700 and the second limiting rib 800 are parallel to each other.

[0142] The first limiting rib 700 is provided with a first connecting hole 710, which penetrates the first limiting rib 700 along the thickness direction; the second limiting rib 800 is provided with a second connecting hole 810, which penetrates the second limiting rib 800 along the thickness direction.

[0143] Specifically, the axis of the first connecting hole 710 coincides with the axis of the second connecting hole 810, and the diameter of the first connecting hole 710 and the diameter of the second connecting hole 810 are equal.

[0144] In some embodiments of this application, the end of the first column 612 facing away from the second column 614 passes through the first connecting hole 710, and the first annular step 611 contacts the side of the first limiting rib 700 facing the second limiting rib 800. The outer wall of the first column 612 contacts the hole wall of the first connecting hole 710, so as to form a limiting effect on the first column 612 through the first connecting hole 710, thereby improving the stability of the first column 612 in the first connecting hole 710.

[0145] In addition, the end of the second column 614 facing away from the first column 612 passes through the second connecting hole 810, and the second annular step 613 and the second limiting rib 800 make smooth contact with the side facing the first limiting rib 700. The outer wall of the second column 614 makes smooth contact with the hole wall of the second connecting hole 810, so as to form a limiting effect on the second column 614 through the second connecting hole 810, thereby improving the stability of the second column 614 in the second connecting hole 810.

[0146] It is understandable that, since the side of the first limiting rib 700 facing the second limiting rib 800 contacts the first annular step 611, and the side of the second limiting rib 800 facing the first limiting rib 700 contacts the second annular step 613, the first limiting rib 700 and the second limiting rib 800 form a limiting structure for the limiting rod 610, preventing the limiting rod 610 from wobbling between the first limiting rib 700 and the second limiting rib 800, thereby improving the stability of the connection between the first limiting rib 700 and the second limiting rib 800 and the limiting rod 610, and thus improving the stability of the connection between the first limiting rib 700 and the second limiting rib 800 and the inertial block 600.

[0147] Since the first limiting rib 700 and the second limiting rib 800 are in smooth contact with the limiting rod 610, the smoothness of the rotation of the limiting rod 610 relative to the first limiting rib 700 and the second limiting rib 800 is improved, thereby improving the smoothness of the rotation of the inertial block 600 relative to the base 100, and improving the smoothness of the switching of the inertial block 600 between the first state and the second state, thereby ensuring the sensitivity of the inertial block 600 to the door handle limit.
