Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a door handle assembly, a door, and a vehicle. Background Technology

[0002] With the rapid development of the automotive market, vehicles have gradually become indispensable products in life and production. Currently, many car door handles use electronic switches for unlocking. In order to open the door even when the vehicle loses power, most vehicles are equipped with a mechanical emergency opening method. However, existing car door handles have problems with cumbersome operation, high learning costs, and low efficiency in emergency opening methods, which not only affect the user experience but also limit the ability to open quickly in emergencies. Utility Model Content

[0003] This application provides a door handle assembly, a door, and a vehicle. The emergency opening method is simple to operate, requires no learning to master, is highly efficient, provides a good user experience, and can be quickly opened in emergency situations.

[0004] The first aspect of this application provides a vehicle door handle assembly, which is installed on a vehicle door. The vehicle door handle assembly includes a handle component and an unlocking component. The vehicle door includes an outer panel and an inner panel, which are spaced apart. The interior of the vehicle door refers to the space between the inner panel and the outer panel.

[0005] The handle component is fixed to the vehicle door, and the unlocking component is rotatably connected to the vehicle door. The unlocking component and the handle component together form at least one side of the handle groove. The unlocking component is connected to the vehicle door lock; when the unlocking component is subjected to external force, it rotates to unlock the vehicle door lock. Compared to solutions where the handle groove is entirely located in the handle component or entirely in the unlocking component, in this application, the unlocking component and the handle component together form at least one side of the handle groove, which can reduce the volume of the vehicle door handle assembly and the space occupied by the vehicle door handle assembly, thus saving space.

[0006] In this embodiment, emergency unlocking can be performed by pulling the unlocking mechanism in any emergency situation. There is no restriction that emergency unlocking can only be performed in a certain emergency situation. Furthermore, by reaching into the handle groove and pulling hard, the unlocking mechanism can be activated, just like the normal action of opening the car door. No learning is required to perform emergency unlocking, thus ensuring the safety of drivers and passengers in emergency situations.

[0007] In some possible implementations, both the handle and the unlocking mechanism are connected to the door via a mounting base. That is, the handle is fixedly connected to the mounting base, and the unlocking mechanism is rotatably connected to the mounting base. The mounting base can be integrally molded with the door, or it can be integrally molded with the handle, or the mounting base can be molded separately, the handle is assembled onto the mounting base, and then the mounting base is fixed to the inside of the door.

[0008] In some possible implementations, the outer surface of the handle is located on the outside of the door, the opening of the handle groove is located on the outer surface, and the unlocking element is located on the side of the handle facing away from the outer surface. That is, the unlocking element is located inside the door.

[0009] In the above implementation, the unlocking component is blocked by the handle component and the outer panel of the door, making it invisible. Only the outer surface of the handle component and the opening of the handle groove are exposed in the door handle assembly. This can reduce the appearance gaps of the handle assembly, improve its refinement and aesthetics, and better prevent foreign objects such as dust and rainwater from entering the interior of the door handle assembly.

[0010] In some possible implementations, the handle includes a panel and an enclosure. The panel includes an outer surface and an inner surface facing away from each other, with the outer surface located on the outside of the door and the inner surface facing the inside of the door. The panel has a first groove that extends through the outer surface and the inner surface. The unlocking component includes an operating part that faces the inner surface. The enclosure is connected to the inner surface, and the enclosure and the operating part enclose a second groove. The first groove and the second groove communicate to form a handle groove.

[0011] In the above implementation, in an emergency, a person can pass their hand through the first slot and then into the second slot to contact the operating part, and then pull the unlocking component to unlock the door. This not only facilitates unlocking the door in an emergency but also avoids the unlocking component being exposed externally, which would increase the visual gaps in the door handle assembly.

[0012] In some possible implementations, the operating part forms the top wall of the handle groove. The operating part includes a first arc-shaped plate, one end of which is spaced apart from the inner surface, and the other end of which extends upward at an angle away from the panel.

[0013] In the above implementation, after a person inserts their hand into the handle groove through the opening, their fingers naturally bend upwards to grasp the operating part, which facilitates the application of force and improves unlocking efficiency in emergency situations. One end of the first arc-shaped plate is spaced apart from the inner surface, which provides space for the rotation of the unlocking component and prevents interference between the inner surface and the unlocking component.

[0014] In some possible implementations, an extension plate protrudes from the inner surface, the extension plate surrounds the first groove, and at least a portion of the extension plate is located within the gap between the first arcuate plate and the inner surface.

[0015] In the above implementation method, by setting an extension plate, the gap between the first arc-shaped plate and the inner wall surface can be blocked, thereby improving the sealing performance of the door handle assembly.

[0016] In some possible implementations, a portion of the first curved plate is stacked on top of the extension plate.

[0017] In the above implementation, the extension plate can support the first arc-shaped plate and improve the sealing performance of the door handle.

[0018] In some possible implementations, a first inclined surface is provided on the side of the first arc-shaped plate opposite to the inner surface, and a second inclined surface is provided on the side of the extension plate away from the inner surface, with the first inclined surface stacked on top of the second inclined surface.

[0019] The above implementation method can both enable the extension plate to support the first arc plate and make the two surfaces of the first arc plate along its thickness direction flush with the two surfaces of the extension plate along its thickness direction, thereby increasing the structural compactness of the door handle assembly.

[0020] In some possible implementations, a seal is provided on the outer periphery of the operating part.

[0021] In the above implementation method, setting a seal can improve the sealing performance of the door handle assembly.

[0022] In some possible implementations, the enclosure includes a second arcuate plate that forms the bottom wall of the handle groove, one end of the second arcuate plate being connected to the inner surface, and the other end of the second arcuate plate extending upward at an angle away from the panel.

[0023] In the above implementation, an upwardly curved handle groove is formed between the second and first arc-shaped plates. When a person places their hand into the handle groove, it will naturally curve upward under the guidance of the second arc-shaped plate, allowing the hand to reach the operating part more quickly and improving unlocking efficiency in emergency situations. The inner surface of the second arc-shaped plate facing the handle groove can be decorated with a starry sky light or other design to enhance aesthetics.

[0024] In some possible implementations, a side plate is also connected between the first and second arc-shaped plates to improve sealing performance.

[0025] In some possible implementations, the unlocking component includes a first driving component, which comprises a first connecting portion, an operating portion, and a first driving swing arm. The first connecting portion and the operating portion are fixedly connected along a first direction, and the first driving swing arm and the first connecting portion are fixedly connected along a second direction. The first direction is parallel to the width direction of the door, and the second direction is parallel to the length direction of the door. The first connecting portion is rotatably connected to the door. Optionally, the first connecting portion can be rotatably connected to the door via a mounting bracket. For example, the mounting bracket is provided with a first shaft, and the first connecting portion is rotatably connected to the first shaft. The handle and the operating portion form at least one side of the handle groove. The first driving swing arm extends along the first direction, and the end of the first driving swing arm away from the first connecting portion is used to connect with the door lock.

[0026] In the above implementation method, the unlocking component has a simple structure and complete functions. The first connecting part can facilitate the rotatable connection between the unlocking component and the mounting base. The operating part and the handle component form at least one side of the handle groove, which is convenient for human hand contact and operation. The first drive swing arm can facilitate the movement of the pull cable to unlock the door lock.

[0027] In some possible implementations, the unlocking component includes a first drive component and a second drive component, both of which are rotatably connected to the mounting base. The first drive component and the second drive component are slidably connected. A portion of the first drive component and the handle component form at least one side of the handle groove. The second drive component is used to connect with the door lock.

[0028] In the above implementation, by setting a first driving component and a second driving component and making the first driving component and the second driving component slide together, when the first driving component rotates, it drives the second driving component to rotate. At the same time, the second driving component slides relative to the first driving component, which can increase the stroke of the pull cable connected to the second driving component. Even when the interior space of the car door is small, the pull cable can have sufficient stroke, which can improve the reliability of emergency unlocking and save space.

[0029] In some possible implementations, the first driving member includes a first connecting portion, an operating portion, and a first driving swing arm. The first connecting portion and the operating portion are fixedly connected along a first direction, and the first driving swing arm and the first connecting portion are fixedly connected along a second direction. The first direction is parallel to the width direction of the door, and the second direction is parallel to the length direction of the door. The first connecting portion is rotatably connected to the door. Optionally, the first connecting portion can be rotatably connected to the door via a mounting base. For example, the mounting base is provided with a first shaft, and the first connecting portion is rotatably connected to the first shaft. The handle and the operating portion form at least one side of the handle groove. The first driving swing arm extends along the first direction, and the end of the first driving swing arm away from the first connecting portion is slidably connected to the second driving member.

[0030] In the above implementation, the first connecting part facilitates the connection between the unlocking component and the door rotation, the operating part and the handle component form a handle groove, facilitating hand contact and operation, and the first drive arm facilitates connection with the second drive component. Furthermore, this structure's first drive component is relatively compact, occupies less space, and improves space utilization.

[0031] In some possible implementations, the second drive member includes a body, a second drive arm, and an unlocking arm, with the body rotatably connected to the door. Optionally, the body is rotatably connected to the door via a mounting bracket; for example, the mounting bracket has a second shaft, and the body of the second drive member is rotatably connected to the second shaft. One end of the second drive arm and one end of the unlocking arm are respectively fixed to the two ends of the body along a second direction. The second drive arm extends along a first direction, and the unlocking arm extends along a third direction, which is the thickness direction of the door. The end of the second drive arm away from the body is slidably connected to the end of the first drive arm away from the first connecting portion, and the end of the unlocking arm away from the body is used to connect to the door lock.

[0032] In the above implementation, the main body supports the second drive arm and the unlocking arm, and facilitates the connection between the second drive component and the door. The second drive arm allows the second drive component to connect smoothly with the first drive component, and the unlocking arm allows the second drive component to smoothly unlock the door lock. Furthermore, this structure of the second drive component is relatively compact, occupies little space, and improves space utilization.

[0033] In some possible implementations, the end of the first drive arm away from the first connecting part is provided with a groove, and the end of the second drive arm away from the main body is provided with a slide rod; or, the end of the first drive arm away from the first connecting part is provided with a slide rod, and the end of the second drive arm away from the main body is provided with a groove; the slide rod slides in connection with the groove; the end of the unlocking arm away from the main body is used to unlock the door lock.

[0034] In the above implementation method, the structure of the sliding rod and the sliding groove is simple and easy to implement. The first driving component and the second driving component are connected through the sliding rod and the sliding groove structure. When the first driving component is reset, the sliding rod slides in the sliding groove, so that the first driving component drives the second driving component to reset synchronously. There is no need to set an additional reset structure for the second driving component, which reduces the number of parts in the door handle assembly.

[0035] In some possible implementations, the door handle assembly further includes a first reset member for resetting the first drive member. Optionally, the first reset member may be sleeved on the first shaft.

[0036] In the above implementation, under normal circumstances, the first reset component is in a pre-tightened state. In an emergency, a person inserts their hand into the handle slot and applies external force to the operating part. This external force overcomes the pre-tightening force of the first reset component, causing the unlocking component to rotate and thus unlocking the door lock. When the person removes their hand, the external force applied to the operating part disappears simultaneously, at which point the first reset component resets, causing the unlocking component to reset as well.

[0037] In some possible implementations, the first reset element includes a first torsion spring, which is sleeved on the first shaft, with one torsion foot of the first torsion spring abutting against the first connecting portion and the other torsion foot of the first torsion spring abutting against the mounting base.

[0038] In some possible implementations, the first connecting part includes a first connecting arm and a second connecting arm, one end of the first connecting arm and one end of the second connecting arm are respectively sleeved on the first shaft, and a first torsion spring is located between the first connecting arm and the second connecting arm; the first torsion spring includes a first sub-torsion spring and a second sub-torsion spring, one torsion foot of the first sub-torsion spring abuts against the first connecting arm, one torsion foot of the second sub-torsion spring abuts against the second connecting arm, and the other torsion foot of the first sub-torsion spring and the other torsion foot of the second torsion spring are fixedly connected to form a hook part, and the hook part is fixedly connected to the mounting base.

[0039] In some possible implementations, the first connecting part includes a first connecting arm and a second connecting arm. One end of the first connecting arm and one end of the second connecting arm are respectively sleeved on the first shaft. The first resetting member includes a first concave cam, a second concave cam, and a first elastic member. The first concave cam, the second concave cam, and the first elastic member are sequentially sleeved on the first shaft and are all located between the first connecting arm and the second connecting arm. The first concave cam and the second concave cam mesh. When the first connecting arm rotates, it drives the first concave cam to rotate. The first concave cam pushes the second concave cam to move axially along the first shaft, causing the first elastic member to compress. After the external force disappears, the first elastic member resets, causing the first concave cam and the second concave cam to cooperate in driving the first driving member to reset.

[0040] In some possible implementations, the door handle assembly also includes a first switch, which is an electronically controlled switch, and is located on the surface of the unlocking element opposite to the handle groove.

[0041] In the above implementation, under normal circumstances, when it is necessary to unlock the car door lock, when a person puts their hand into the handle slot and touches the first switch, the first switch will send an unlock signal to the controller. After receiving the unlock signal, the controller sends a drive signal to the drive component. After receiving the drive signal, the drive component starts to drive the cable to move, so that the cable drives the car door lock to unlock.

[0042] In some possible implementations, the handle component also has a groove on its outer surface. The groove and handle slot are spaced apart, and the distance between the groove and the opening side of the door is less than the distance between the handle slot and the opening side of the door. The door handle assembly also includes a second switch and a cover plate. The second switch is an electronically controlled switch connected to the door. Optionally, the second switch is connected to the door via a mounting bracket. One end of the second switch extends into the groove, and the cover plate is disposed within the groove to cover the second switch. The side of the cover plate facing the groove abuts against one end of the second switch.

[0043] In the above implementation, the groove is closer to the opening side of the door than the handle groove, so that the second switch and cover plate at the groove location are closer to the opening side of the door. After pressing the cover plate, the door can be opened smoothly without having to move away.

[0044] In some possible implementations, the surface of the cover plate facing away from the groove is flush with the surface of the handle component located on the outside of the door.

[0045] The above implementation methods can enhance the aesthetics of the door handle assembly.

[0046] In some possible implementations, the door handle assembly also includes a mechanical lock cylinder connected to the door. Optionally, the mechanical lock cylinder is connected to the door via a mounting bracket. The end of the mechanical lock cylinder with the lock hole extends into a recess, and a cover plate also conceals the mechanical lock cylinder.

[0047] In the above implementation method, when the vehicle loses power, the user can open the cover, insert the mechanical key into the lock hole of the mechanical lock cylinder to open the vehicle's central locking system, and then operate the unlocking mechanism from the handle slot to unlock the door lock, so that the door can be opened.

[0048] In some possible implementations, a second connecting part is connected to the side of the cover plate facing the groove. The second connecting part extends into the interior of the door and is rotatably connected to the door. Optionally, the second connecting part is rotatably connected to the door via a mounting bracket, for example, the mounting bracket is provided with a third shaft, and the second connecting part is rotatably connected to the third shaft.

[0049] In the above implementation, the cover plate is rotatably connected to the car door, which makes it easy to open the cover plate. After the cover plate is opened, it remains connected to the car door, which can prevent the cover plate from falling off.

[0050] In some possible implementations, the door handle assembly also includes a second reset member for resetting the cover plate. Optionally, the second reset member is sleeved on a third axle.

[0051] In the above implementation, the second reset component has a pre-tightening force. This pre-tightening force keeps the cover plate closed, and it must be less than the supporting force of the second switch on the cover plate to avoid excessive pre-tightening force that could cause the second switch to be deformed. It also ensures that the outer surface of the cover plate is flush with the outer surface of the handle assembly, improving the aesthetics of the handle assembly. When the cover plate needs to be opened, a person can apply force to it to overcome the pre-tightening force, allowing the cover plate to open. After the person releases the cover plate, the second reset component gradually resets, which in turn causes the cover plate to reset.

[0052] In some possible implementations, the second reset element is a second torsion spring, which is sleeved on the third shaft. One torsion foot of the second torsion spring abuts against the second connecting part, and the other torsion foot of the second torsion spring abuts against the mounting base.

[0053] In some possible implementations, the second connecting part includes a third connecting arm and a fourth connecting arm. One end of the third connecting arm and one end of the fourth connecting arm are respectively sleeved on the third shaft. The second torsion spring is located between the third connecting arm and the fourth connecting arm. The second torsion spring includes a third sub-torsion spring and a fourth sub-torsion spring. One torsion foot of the third sub-torsion spring abuts against the third connecting arm, and one torsion foot of the fourth sub-torsion spring abuts against the fourth connecting arm. The other torsion feet of the third sub-torsion spring and the other torsion foot of the fourth torsion spring are fixedly connected to form a hook portion, and the hook portion is fixedly connected to the mounting base.

[0054] In some possible implementations, the second connecting part includes a third connecting arm and a fourth connecting arm. One end of the third connecting arm and one end of the fourth connecting arm are respectively sleeved on the third shaft. The second resetting member includes two third concave cams, two fourth concave cams, and a second elastic member. The two third concave cams, two fourth concave cams, and the second elastic member are all sleeved on the third shaft and are all located between the third and fourth connecting arms. One third concave cam is fixed to the side of the third connecting arm facing the fourth connecting arm, and the other third concave cam is fixed to the side of the fourth connecting arm facing the third connecting arm. The two fourth concave cams respectively mesh with the two third concave cams. The second elastic member is located between the two fourth concave cams, and both ends of the second elastic member abut against the two fourth concave cams respectively.

[0055] In some possible implementations, a sealing ring is provided in the groove, and the edge of the cover plate facing the groove abuts against the sealing ring.

[0056] In the above implementation method, the sealing ring can increase the sealing performance and prevent foreign objects from entering the groove and affecting vehicle safety. In addition, the sealing ring can also prevent vibration and abnormal noise.

[0057] A second aspect of this application provides a door handle assembly, which is installed on a vehicle door. The door handle assembly includes: a handle component, a second switch, and a cover plate. The handle component is fixed to the vehicle door. The handle component has a handle groove and a recess. The outer surface of the handle component, the opening of the handle groove, and the opening of the recess are all located on the outside of the vehicle door. The recess and the handle groove are arranged at intervals, and the distance between the recess and the opening side of the vehicle door is less than the distance between the handle groove and the opening side of the vehicle door. The second switch is connected to the vehicle door, one end of the second switch extends into the recess, and the cover plate is disposed in the recess to cover the second switch. The side of the cover plate facing the recess abuts against the second switch. Optionally, the handle component and the second switch can be connected to the vehicle door through a mounting bracket, the mounting bracket being fixed inside the vehicle door, and both the handle component and the second switch are connected to the mounting bracket.

[0058] In some possible implementations, the door handle assembly also includes a mechanical lock cylinder connected to the door. The mechanical lock cylinder can be connected to the door via a mounting bracket, and one end of the mechanical lock cylinder with a lock hole extends into a recess. A cover plate also conceals the mechanical lock cylinder.

[0059] In some possible implementations, the cover plate is connected to a second connecting part on the side facing the groove. The second connecting part extends into the interior of the door and is rotatably connected to the door. The second connecting part can be rotatably connected to the door via a mounting bracket, for example, the mounting bracket is provided with a third shaft, and the second connecting part is rotatably connected to the third shaft.

[0060] In some possible implementations, the door handle assembly also includes a second reset element for resetting the cover plate.

[0061] In some possible implementations, a sealing ring is provided in the groove, and the edge of the cover plate facing the groove abuts against the sealing ring.

[0062] A third aspect of this application provides a vehicle door, including the vehicle door handle assembly of the first or second aspect of this application.

In summary, the use of prefixes to distinguish descriptive objects in this application does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and the use of such prefixes should not constitute unnecessary restrictions.

[0089] To facilitate understanding, the relevant terms that may be involved in the embodiments of this application will be introduced below.

[0090] refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in an embodiment of this application. This application provides a vehicle 1000. It should be understood that the vehicle 1000 here is a vehicle in a broad sense, which can be a means of transportation (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.). Furthermore, the robot can be an automated guided vehicle (AGV), a walking conversational robot, or a service robot.

[0091] refer to Figure 2 and Figure 3 , Figure 2 for Figure 1 A partial structural schematic diagram of the vehicle 1000 shown. Figure 3 for Figure 2A sectional view taken along section line AA. Vehicle 1000 includes a door 1100, to which a door handle assembly 2000 is connected. The door handle assembly 2000 can lock or unlock the door 1100. The door 1100 includes an inner panel 1200 and an outer panel 1300 fixedly connected, spaced apart. The space between the inner panel 1200 and the outer panel 1300 can be used to install wiring, parts of the door handle assembly 2000, and connectors. The side of the inner panel 1200 facing away from the outer panel 1300 is located inside the passenger compartment of vehicle 1000, and the side of the outer panel 1300 facing away from the inner panel 1200 is located outside vehicle 1000, forming the exterior surface of the door 1100.

[0092] Normally, the door handle assembly 2000 has an unlock switch, which the user can touch or press to open the door 1100. However, since the unlock switch is an electronically controlled switch, in emergency situations such as a car accident or fire, the vehicle 1000 may lose power, causing the unlock switch to malfunction. If the door 1100 cannot be opened in time, the lives of the driver and passengers in the vehicle may be in danger.

[0093] In order to enable the door 1100 to be opened when the vehicle 1000 loses power, an emergency switch can be configured for the vehicle 1000. The emergency switch is generally a mechanical switch and is integrated into the door handle assembly 2000.

[0094] The following describes several types of door handle assemblies with emergency switches.

[0095] In some embodiments, the door handle assembly includes a handle component with a handle groove. In the event of a collision, a cable pops out from the handle groove. This cable connects to the door lock; pulling the cable unlocks the door. However, this method of popping out the cable only in the event of a collision, lacking a mechanical backup. In other emergencies, the cable may fail to pop out, seriously endangering the safety of the driver and passengers. Furthermore, this design relies on a motor and spring to activate the cable, which may malfunction over time.

[0096] In other embodiments, the door handle assembly includes a handle component and a cover. The handle component has a receiving groove containing a pull cable. One end of the pull cable is connected to the door lock. The cover is connected to the handle component and covers the receiving groove. The other end of the pull cable is connected to the side of the cover facing the receiving groove. In an emergency, the cover can be opened, causing the pull cable to move and unlock the door lock. However, this method of unlocking the door by opening the cover is not readily apparent in an emergency and requires extensive knowledge of the vehicle model and its emergency unlocking mechanism (opening the cover). If the user is unfamiliar with the vehicle, they will need time to find the emergency switch. Excessive learning time in an emergency could endanger the safety of the driver and passengers. Furthermore, the opened cover is also aesthetically unappealing.

[0097] To solve the above problems, refer to Figure 4 and Figure 5 , Figure 4 This is a structural schematic diagram of the door handle assembly 2000 provided in an embodiment of this application. Figure 5 for Figure 4 The diagram shows a cross-sectional view of the door handle assembly 2000 taken along section line BB. This application embodiment provides another door handle assembly 2000, which is installed on a door 1100, with a portion of the assembly located inside the door 1100 and another portion extending outside the door 1100 to facilitate the user opening the door 1100.

[0098] The door handle assembly 2000 includes handle component 100 and unlocking component 200. Figure 4 and Figure 5 The purpose of this illustration is solely to demonstrate the structure of the door handle assembly 2000, and it is not intended to specifically limit the connection positions, specific structures, or quantities of the various devices. Furthermore, the structure illustrated in this application's embodiments does not constitute a specific limitation on the door handle assembly 2000. In other embodiments of this application, the door handle assembly 2000 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0099] Handle component 100 is fixed to door 1100, and unlocking component 200 is rotatably connected to door 1100. Unlocking component 200 and handle component 100 form at least one side of handle groove 300, and unlocking component 200 is connected to door lock. When unlocking component 200 is subjected to external force, it rotates to unlock the door lock. Exemplarily, unlocking component 200 is connected to door lock via a pull cable.

[0100] Optionally, the handle 100 and the unlocking component 200 can be connected to the door via the mounting base 700. The mounting base 700 is fixed inside the door 1100, the handle 100 is fixed to the mounting base 700, and the unlocking component 200 is rotatably connected to the mounting base 700. The mounting base 700 can be integrally formed with the door 1100, or the mounting base 700 can be integrally formed with the handle 100, or the mounting base 700 can be formed separately, the handle 100 can be assembled into the mounting base 700, and then the mounting base 700 can be fixed inside the door 1100.

[0101] The mounting bracket 700 is fixed inside the door 1100, which refers to the space between the inner panel 1200 and the outer panel 1300 of the door 1100. The mounting bracket 700 can be fixed to the inner panel 1200. Taking the mounting bracket 700 and the handle component 100 as at least partly integrally formed, or the mounting bracket 700 as separately formed, the mounting bracket 700 and the inner panel 1200 can be welded, glued, or connected using fasteners such as bolts. For example, the mounting bracket 700 can be provided with three connecting ears, two of which are located on the upper part of the mounting bracket 700 and the other connecting ear is located on the lower part of the mounting bracket 700. When installing the door handle assembly 2000, first hang the two connecting ears located on the upper part on the connector provided on the inner panel 1200, and then adjust the position of the door handle assembly 2000. After the position of the door handle assembly 2000 is adjusted into place, use fasteners such as bolts to fix the connecting ears and the connector. The mounting base 700 only needs to be able to support the handle 100; its specific structure is not limited.

[0102] refer to Figure 6 , Figure 6 A schematic diagram illustrating the state changes of the door handle assembly 2000 provided in this embodiment of the application. Figure 6 Figure (a) shows the state before unlocking. At this time, the unlocking component 200 is locked, and the door lock is also locked. In an emergency, a person can put their hand into the handle slot 300 and pull the unlocking component 200 forcefully. At this time, the unlocking component 200 can rotate. When the unlocking component 200 rotates, it will separate from the handle component 100, so as to drive the cable to move. The cable will then unlock the door lock. Figure 6 Figure (b) shows the state after unlocking. At this time, the unlocking component 200 is in the unlocked state, and the door lock is also in the unlocked state, so that the door 1100 can be opened. For example, the maximum opening degree of the unlocking component 200 is about 8 degrees, the unlocking angle is about 5.3 degrees, and the maximum movement of the pull cable is about 20 millimeters.

[0103] As can be seen from the above, in this embodiment, emergency unlocking can be performed by pulling the unlocking component 200 in any emergency situation. There is no restriction that emergency unlocking is only possible under certain emergency conditions. Furthermore, simply reaching into the handle groove 300 and pulling forcefully will activate the unlocking component 200, identical to the normal opening of the door 1100. Emergency unlocking can be performed without any learning process, ensuring the safety of drivers and passengers in emergency situations. In other words, the door handle assembly 2000 provided in this embodiment is simple to operate, has a low learning cost, is highly efficient, provides a good user experience, can be quickly opened in emergency situations, and also has the advantages of high reliability and resistance to failure.

[0104] In addition, compared to the solution where the handle groove 300 is completely set in the handle piece 100 or completely set in the unlocking piece 200, in this embodiment, the unlocking piece 200 and the handle piece 100 together constitute at least one side of the handle groove 300, which can reduce the volume of the door handle assembly 2000 and reduce the space occupied by the door handle assembly 2000, thus saving space.

[0105] In some embodiments, reference is made to Figure 5 and Figure 6 The door handle assembly 2000 also includes a first switch 400, which is located on the surface of the unlocking member 200 opposite to the handle groove 300. The first switch 400 can be a capacitive switch, a type of electronic switch. Normally, when the door lock needs to be unlocked, a person places their hand into the handle groove 300 and touches the first switch 400. The first switch 400 then sends an unlock signal to the controller. Upon receiving the unlock signal, the controller sends a drive signal to the drive component. Upon receiving the drive signal, the drive component activates to move the cable, thereby unlocking the door lock. The controller can be a vehicle controller or an auxiliary controller electrically connected to the vehicle controller. The drive component can be a motor or a cylinder, etc.

[0106] In some embodiments, reference is made to Figure 5 , Figure 6 and Figure 7 , Figure 7This is a partial cross-sectional view of the door handle assembly 2000 provided in this application embodiment. The outer surface 101 of the handle component 100 is located on the outside of the door 1100, and the opening of the handle groove 300 is provided on the outer surface 101. The unlocking component 200 is located on the side of the handle component 100 facing away from the outer surface 101. That is, regardless of whether the unlocking component 200 is in the locked or unlocked state, the unlocking component 200 is covered by the handle component 100 and the outer panel 1300 of the door 1100. The unlocking component 200 is located inside the door 1100 and is not visible. Only the outer surface 101 of the handle component 100 and the opening of the handle groove 300 are exposed. This can reduce the appearance gaps of the handle component 100 assembly, improve the refinement and aesthetics, and better prevent foreign objects such as dust and rainwater from entering the interior of the door handle assembly 2000. The entire door handle assembly 2000 is a fixed semi-concealed external handle. Its design is aesthetically pleasing, its opening function is good, and its aerodynamic characteristics are excellent, taking into account both aesthetics and emergency opening experience.

[0107] In some embodiments, reference is made to Figure 5 and Figure 7 The handle 100 includes a panel 110 and an enclosure 120. An outer surface 101 is disposed on the panel 110. The panel 110 also includes an inner surface 102 disposed opposite to the outer surface 101. The inner surface 102 and the outer surface 101 are two surfaces of the panel 110 that are opposite to each other along their thickness direction, with the inner surface 102 facing the interior of the door 1100. The panel 110 has a first groove 130 that penetrates both the outer surface 101 and the inner surface 102. For example, the panel 110 can be rectangular. Alternatively, the panel 110 can also be elliptical, circular, or other regular shapes, or it can be an irregular shape. The unlocking member 200 includes an operating part 211, which is opposite to the inner surface 102. The enclosure 120 is connected to the inner surface 102. The enclosure 120 and the operating part 211 enclose a second groove 140. The first groove 130 and the second groove 140 communicate to form a handle groove 300. The opening of the handle groove 300 is on the side of the first groove 130 away from the second groove 140.

[0108] For example, the enclosure 120 can be integrally formed with the mounting base 700, or the enclosure 120 and the panel 110 can be integrally formed, and the panel 110 can be fixedly connected to the mounting base 700 through the enclosure 120 by means of snap-fit ​​or slot. Alternatively, the enclosure 120, the mounting base 700 and the panel 110 can be integrally formed.

[0109] In an emergency, a person can pass their hand through the first slot 130 and then into the second slot 140, making contact with the operating part 211, and then pull the unlocking part 200 to unlock the door. This not only facilitates unlocking the door 1100 in an emergency, but also prevents the unlocking part 200 from being exposed, which would increase the appearance of the door handle assembly 2000.

[0110] In some embodiments, reference is made to Figure 7 , Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the split structure of a partial structure of the door handle assembly 2000 provided in an embodiment of this application. Figure 9 for Figure 7 The diagram shows a split structure from another perspective of the partial structure shown. The operating part 211 forms the top wall of the handle groove 300. The operating part 211 includes a first arc-shaped plate 212. One end of the first arc-shaped plate 212 is spaced apart from the inner surface 102, and the other end of the first arc-shaped plate 212 extends upward at an angle away from the panel 110.

[0111] After a person inserts their hand into the handle groove 300 through the opening, their fingers naturally bend upwards to grasp the operating part 211, which facilitates the application of force and improves unlocking efficiency in emergency situations. One end of the first arc-shaped plate 212 is spaced apart from the inner surface 102, which provides space for the rotation of the unlocking part 200 and prevents interference between the inner surface 102 and the unlocking part 200.

[0112] For example, the handle groove 300 may include a top wall and a side wall disposed opposite each other, and a side wall connecting the top wall and the bottom wall. The unlocking member 200 and the handle member 100 constituting at least one side of the handle groove 300 means that the unlocking member 200 and the handle member 100 may be two of the top wall, bottom wall, and side wall, respectively. For example, the unlocking member 200 and the handle member 100 may constitute the top wall and bottom wall of the handle groove 300, respectively. Alternatively, the unlocking member 200 and the handle member 100 may constitute the top wall and side wall of the handle groove 300, respectively. Alternatively, the unlocking member 200 and the handle member 100 may constitute the bottom wall and side wall of the handle groove, respectively.

[0113] The statement that the unlocking component 200 and the handle component 100 constitute at least one side of the handle groove 300 can also mean that the unlocking component 200 and the handle component 100 are both part of one of the three components. For example, the unlocking component 200 and the handle component 100 are both part of the top wall of the handle groove 300. In this case, the bottom wall and side wall of the handle groove 300 may be formed by other additional components.

[0114] The fact that the unlocking component 200 and the handle component 100 constitute at least one side of the handle groove 300 can also refer to: the unlocking component 200 constituting two of the three, and the handle component 100 constituting the remaining one; or, the unlocking component 200 constituting one of the three, and the handle component 100 constituting the remaining two. For example: the unlocking component 200 constituting the top wall, and the handle component 100 constituting the side wall and the bottom wall; or, the unlocking component 200 constituting a part of the side wall and the top wall, and the handle component 100 constituting another part of the side wall and the bottom wall.

[0115] The following describes one implementation method, with reference to Figure 7 , Figure 8 and Figure 9 The enclosure 120 includes a second arc-shaped plate 121, which forms the bottom wall of the handle groove 300. One end of the second arc-shaped plate 121 is connected to the inner surface 102, and the other end of the second arc-shaped plate 121 extends upward at an angle away from the panel 110. Thus, an upwardly curved handle groove 300 is formed between the second arc-shaped plate 121 and the first arc-shaped plate 212. When a hand is inserted into the handle groove 300, it will naturally curve upward under the guidance of the second arc-shaped plate 121, allowing the hand to find the operating part 211 more quickly and improving unlocking efficiency in emergency situations. The inner surface 102 of the second arc-shaped plate 121 facing the handle groove 300 can be decorated with a starry sky design to enhance aesthetics.

[0116] For example, refer to Figure 8 and Figure 9 Two side plates 310 are connected between the first arc-shaped plate 212 and the second arc-shaped plate 121, and these two side plates 310 form the sidewalls of the handle groove 300. One side plate 310 covers the gap between one side of the first arc-shaped plate 212 and one side of the second arc-shaped plate 121, while the other side plate 310 covers the gap between the other side of the first arc-shaped plate 212 and the other side of the second arc-shaped plate 121, thereby increasing the sealing of the door handle assembly 2000. The transitions between the side plate 310 and the first arc-shaped plate 212, and between the side plate 310 and the second arc-shaped plate 121, are all rounded.

[0117] Optionally, the side plate 310 includes a first side plate 320 and a second side plate 330, with the first side plate 320 and the first arc-shaped plate 212 integrally formed. The second side plate 330 and the second arc-shaped plate 212 are integrally formed, and the side of the first side plate 320 away from the first arc-shaped plate 212 and the side plate 330 away from the second arc-shaped plate 121 are fixedly connected. For example, the first side plate 320 and the second side plate 330 can be welded or bonded together.

[0118] Alternatively, the side plate 310 can be integrally formed with the second arc plate 121.

[0119] In some embodiments, reference is made to Figure 7 and Figure 9 An extension plate 150 protrudes from the inner surface 102, surrounding the first groove 130. At least a portion of the extension plate 150 is located within the gap between the first arcuate plate 212 and the inner surface 102; that is, the extension plate 150 can be part of the top wall of the second groove 140. By providing the extension plate 150, the gap between the first arcuate plate 212 and the inner wall surface can be blocked, improving the sealing performance of the door handle assembly 2000.

[0120] In some embodiments, reference is made to Figure 10 , Figure 10 for Figure 6 Enlarged schematic diagram at point A. A first inclined surface 214 is provided on the side of the first arc-shaped plate 212 opposite to the inner surface 102, and a second inclined surface 151 is provided on the side of the extension plate 150 away from the inner surface 102. The first inclined surface 214 is stacked on top of the second inclined surface 151. This design allows the extension plate 150 to support the first arc-shaped plate 212, and also ensures that the two surfaces of the first arc-shaped plate 212 along its thickness direction are flush with the two surfaces of the extension plate 150 along its thickness direction, thereby increasing the structural compactness of the door handle assembly 2000.

[0121] For example, a seal 215 may be provided on the outer periphery of the operating part 211. The seal 215 may be injection molded. When the operating part 211 and the extension plate 150 are engaged, and when the operating part 211 and the enclosure 120 are engaged, the seal 215 is pressurized to improve the sealing performance of the door handle assembly 2000.

[0122] Alternatively, in some other embodiments, reference is made to Figure 11 , Figure 11 This is another structural schematic diagram of the connection between the first arc-shaped plate 212 and the extension plate 150 provided in an embodiment of this application. A portion of the first arc-shaped plate 212 is stacked on top of the extension plate 150. Exemplarily, a portion of the first arc-shaped plate 212 near the inner surface 102 is stacked on top of the extension plate 150 so that the extension plate 150 can support the first arc-shaped plate 212 and improve the sealing performance of the door handle assembly 2000.

[0123] In some embodiments, reference is made to Figure 12 , Figure 12 This is another partial structural diagram of the door handle assembly 2000 provided in an embodiment of this application. The unlocking member 200 includes a first driving member 210 and a second driving member 220. Both the first driving member 210 and the second driving member 220 are rotatably connected to the door. Exemplarily, the first driving member 210 and the second driving member 220 can be rotatably connected to the door via a mounting base 700. The first driving member 210 and the second driving member 220 are slidably connected. A portion of the first driving member 210 and the handle member 100 form at least one side of the handle groove 300. The second driving member 220 is used to connect with the door lock.

[0124] Typically, to increase the cabin space of vehicle 1000, the thickness of door 1100 needs to be as thin as possible. Therefore, the internal space of door 1100 is relatively limited along its thickness direction. However, when the unlocking component 200 unlocks the door lock via a cable, the cable needs to move a sufficient distance along the thickness direction of door 1100 to unlock the door lock. By setting up a first driving component 210 and a second driving component 220, and making the first driving component 210 and the second driving component 220 slidably connected, when the first driving component 210 rotates, it drives the second driving component 220 to rotate. At the same time, the second driving component 220 slides and rotates relative to the first driving component 210, which increases the travel of the cable connected to the second driving component 220 and improves the reliability of emergency unlocking.

[0125] Alternatively, in some embodiments, the unlocking component 200 includes only the first driving component 210, with the pull cable directly connected to the first driving swing arm 217 of the first driving component 210. By directly unlocking the door lock via the first driving component 210, the structure of the unlocking component 200 can be simplified, improving assembly convenience.

[0126] In some embodiments, reference is made to Figure 12 In addition to the aforementioned operating part 211, the first driving component 210 also includes a first connecting part 216 and a first driving swing arm 217. The first connecting part 216 and the operating part 211 are fixedly connected along a first direction, and the first driving swing arm 217 and the first connecting part 216 are fixedly connected along a second direction. The first direction is parallel to the width direction of the door 1100, and the second direction is parallel to the length direction of the door 1100. The first direction is also the height direction of the vehicle 1000, and the second direction is also the length direction of the vehicle 1000. Optionally, the first driving swing arm 217 is rotatably connected to the door, which can increase the stability of the unlocking component 200 during operation.

[0127] The first connecting portion 216 is rotatably connected to the vehicle door. For example, both the first connecting portion 216 and the first drive swing arm 217 are rotatably connected to the vehicle door via a mounting base 700. For instance, the mounting base 700 is provided with a first shaft 500, and both the first connecting portion 216 and the first drive swing arm 217 are rotatably connected to the first shaft 500. The handle member 100 and the operating portion 211 constitute at least one side of the handle groove 300. The first drive swing arm 217 extends along a first direction, and one end of the first drive swing arm 217 away from the first connecting portion 216 is slidably connected to the second drive member 220.

[0128] The first connecting part 216 facilitates the rotational connection between the unlocking member 200 and the door. The operating part 211 and the handle member 100 form at least one side of the handle groove 300, facilitating hand contact and operation. The first drive arm 217 facilitates connection with the second drive member 220. Furthermore, the first drive member 210 of this structure is relatively compact, occupies less space, and can improve space utilization.

[0129] In some embodiments, reference is made to Figure 12 The second drive member 220 includes a body part 221, a second drive swing arm 222 and an unlocking swing arm 223. The body part 221 is rotatably connected to the car door. For example, the body part 221 is rotatably connected to the car door through a mounting base 700. For example, the mounting base 700 is also provided with a second shaft 510, and the body part 221 is rotatably connected to the car door through the second shaft 510.

[0130] One end of the second drive swing arm 222 and one end of the unlocking swing arm 223 are respectively fixed to the two ends of the main body 221 along the second direction. The second drive swing arm 222 extends along the first direction, and the unlocking swing arm 223 extends along a third direction, which is the thickness direction of the door 1100 and also the width direction of the vehicle 1000. The end of the second drive swing arm 222 away from the main body 221 is slidably connected to the end of the first drive swing arm 217 away from the first connecting part 216, and the end of the unlocking swing arm 223 away from the main body 221 is used to connect to the door lock. For example, the end of the unlocking swing arm 223 away from the main body 221 is provided with a slot, one end of the pull cable can be connected to the slot, and the other end of the pull cable is connected to the door lock, that is, the unlocking swing arm 223 is connected to the door lock through the pull cable.

[0131] The main body 221 supports the second drive arm 222 and the unlocking arm 223, and facilitates the connection between the second drive component 220 and the mounting base 700. The second drive arm 222 allows the second drive component 220 to connect smoothly with the first drive component 210, and the unlocking arm 223 allows the second drive component 220 to smoothly unlock the door lock. Furthermore, this structure of the second drive component 220 is relatively compact, occupies little space, and improves space utilization.

[0132] The longer the unlocking arm 223 is along the third direction, the greater the stroke of the end of the unlocking arm 223 away from the main body 221 when the unlocking component 200 is running, and the greater the stroke that can drive the cable to move. Designers can determine the length of the unlocking arm 223 according to the stroke that the cable needs to move and the size of the internal space of the door 1100.

[0133] For example, refer to Figure 12The first drive swing arm 217 has a groove 218 at its end away from the first connecting portion 216. The groove 218 extends along a first direction and can be an oblong groove. The second drive swing arm 222 has a slide rod 224 at its end away from the main body portion 221. Alternatively, the first drive swing arm 217 has a slide rod 224, and the second drive swing arm 222 has a groove 218. The slide rod 224 slidably connects to the groove 218, and the unlocking swing arm 223 at its end away from the main body portion 221 is used to unlock the door lock.

[0134] refer to Figure 13 , Figure 13 A schematic diagram showing the state changes of the unlocking component 200 of the door handle assembly 2000 provided in this application embodiment. Figure 13 (a) is a schematic diagram of the unlocking component 200 in the locked state. Figure 13 Figure (b) shows a schematic diagram of the unlocking component 200 in the unlocked state. When a person puts their hand into the handle groove 300 and pulls the operating part 211, the operating part 211 rotates counterclockwise, causing the first connecting part 216 to rotate counterclockwise around the first shaft 500, and also causing the first drive swing arm 217 to rotate counterclockwise. At this time, the slide rod 224 slides and rotates in the slide groove 218, causing the second drive swing arm 222 to rotate clockwise. The second drive swing arm 222 drives the unlocking swing arm 223 to rotate clockwise through the body part 221. The unlocking swing arm 223 drives the pull cable to move, thereby unlocking the door lock.

[0135] refer to Figure 14 , Figure 14 Another schematic diagram illustrating the state changes of the unlocking component 200 of the door handle assembly 2000 provided in this application embodiment. Figure 14 The solid line shows a schematic diagram of the unlocking member 200 in the locked state, and the dashed line shows a schematic diagram of the unlocked state. The first driving member 210 and the second driving member 220 are slidably connected. When the first driving member 210 rotates at a first angle 'a', it can drive the second driving member 220 to rotate at a second angle 'b', and the second angle 'b' is greater than the first angle 'a'. For example, the first angle can be 9 degrees, and the second angle can be 42 degrees. Compared to using the first driving member 210 to directly drive the pull cable, in this embodiment, using the second driving member 220 to drive the pull cable allows for a greater stroke of the pull cable.

[0136] In some embodiments, reference is made to Figure 12 The door handle assembly 2000 also includes a first reset member 600, which is sleeved on the first shaft 500 and is used to reset the first drive member 210.

[0137] Under normal circumstances, the first reset member 600 is in a pre-tightened state, and the pre-tightening force keeps the unlocking member 200 in contact with the extension plate 150. In an emergency, a person can reach into the handle groove 300 and apply external force to the operating part 211. This external force overcomes the pre-tightening force of the first reset member 600, causing the unlocking member 200 to rotate and unlock the door. When the person removes their hand, the external force applied to the operating part 211 disappears simultaneously. At this time, the first reset member 600 resets, causing the unlocking member 200 to reset as well. When the unlocking member 200 resets, the extension plate 150 supports the unlocking member 200 to prevent it from over-resetting. The first drive member 210 and the second drive member 220 are connected by a slide rod 224 and a slide groove 218. When the first reset member 600 drives the first drive member 210 to reset, the slide rod 224 slides in the slide groove 218, so that the first drive member 210 drives the second drive member 220 to reset synchronously. There is no need to set an additional reset structure for the second drive member 220, which reduces the number of parts in the door handle assembly 2000.

[0138] For example, the preload of the first reset member 600 is greater than the force required for the door 1100 to be opened normally. For example, under normal circumstances, it takes a force of 10 Newtons (N) to 50 N to open the door 1100, and the preload of the first reset member 600 needs to be greater than 50 N. Optionally, the preload of the first reset member 600 can be set between 50 N and 150 N to ensure that under normal circumstances, the user can unlock the door through the electronic control switch, and only in an emergency will the emergency switch be activated to unlock the door, so as to protect the emergency switch and avoid damage caused by frequent use of the emergency switch.

[0139] In one possible implementation, refer to Figure 12 The first reset component 600 includes a first torsion spring 610, which is sleeved on the first shaft 500. One torsion foot of the first torsion spring 610 abuts against the first connecting part 216, and the other torsion foot of the first torsion spring 610 abuts against the mounting base 700.

[0140] The first connecting part 216 includes a first connecting arm 230 and a second connecting arm 240. One end of the first connecting arm 230 and one end of the second connecting arm 240 are respectively sleeved on the first shaft 500. A first torsion spring 610 is located between the first connecting arm 230 and the second connecting arm 240. The first torsion spring 610 includes a first sub-torsion spring 611 and a second sub-torsion spring 612. One torsion foot of the first sub-torsion spring 611 abuts against the first connecting arm 230, and one torsion foot of the second sub-torsion spring 612 abuts against the second connecting arm 240. The other torsion foot of the first sub-torsion spring 611 and the other torsion foot of the second sub-torsion spring 612 are fixedly connected to form a hook portion, which is fixedly connected to the mounting base 700. The first sub-torsion spring 611 and the second torsion spring 612 are connected as a whole, which facilitates assembly.

[0141] Exemplarily, the first connecting portion 216 may further include a connecting plate 219, which may form part of at least one side of the handle groove 300. The first connecting arm 230 and the second connecting arm 240 are fixed to one side surface of the connecting plate, and the other side surface of the connecting plate 219 faces the handle groove 300. The connecting plate 219 serves to connect the first connecting arm 230 and the second connecting arm 240, and can also cooperate with the enclosure 120 to provide a sealing function. Optionally, the connecting plate 219 may be a square plate, with one long side of the connecting plate 219 fixedly connected to the operating portion 211, and the other long side of the connecting plate 219 contacting the enclosure 120 to prevent the handle groove 300 from communicating with the interior of the door, and to prevent foreign objects from entering the interior of the door from the handle groove 300.

[0142] The first connecting arm 230 and the second connecting arm 240 can have the same structure. Both the first connecting arm 230 and the second connecting arm 240 are bent rod-shaped members. One end of the first connecting arm 230 and the second connecting arm 240 are rotatably connected to the first shaft 500, and the operating part 211 is connected to the other end of the first connecting arm 230 and the second connecting arm 240. The bending direction of the first connecting arm 230 and the second connecting arm 240 is the same as the bending direction of the first arc plate 212, which facilitates the extension of the first arc plate 212 to cooperate with the handle 100, and also allows the first connecting arm 230 and the second connecting arm 240 to be located inside the door 1100.

[0143] Under normal circumstances, the first torsion spring 610 is in a pre-tensioned state, and the pre-tension force keeps the unlocking member 200 in contact with the extension plate 150. In an emergency, a person can reach into the handle groove 300 and apply external force to the operating part 211. This external force overcomes the pre-tension force of the first torsion spring 610, causing both the first connecting arm 230 and the second connecting arm 240 to rotate around the first shaft 500, thereby unlocking the door lock. When the person removes their hand, the external force applied to the operating part 211 disappears simultaneously, at which point the first torsion spring 610 returns to its original position, causing the unlocking member 200 to return to its original position as well.

[0144] Another possible implementation, refer to Figure 15 , Figure 15This is a partial schematic diagram of another structure of the door handle assembly 2000 provided in this application embodiment. The first connecting portion 216 includes a first connecting arm 230 and a second connecting arm 240. One end of the first connecting arm 230 and one end of the second connecting arm 240 are respectively sleeved on the first shaft 500. The first reset member 600 includes two first concave cams 620, two second concave cams 630, and a first elastic member 640, which can be a compression spring. The two first concave cams 620, the two second concave cams 630, and the first elastic member 640 are all sleeved on the first shaft 500 and are all located between the first connecting arm 230 and the second connecting arm 240. One first concave cam 620 is fixed to the side of the first connecting arm 230 facing the second connecting arm 240, and the other first concave cam 620 is fixed to the side of the second connecting arm 240 facing the first connecting arm 230. The two second concave cams 630 respectively mesh with the two first concave cams 620, and the first elastic member 640 is located between the two second concave cams 630.

[0145] refer to Figure 15 , Figure 15 (a) shows the state diagram of the first reset component when the unlocking component is in the locked state. Figure 15 (b) shows the state of the first reset member when the unlocking member is in the unlocked state. Under normal circumstances, the first elastic member 640 is in a pre-compressed state, providing a pre-tightening force to the unlocking member 200, so that the unlocking member 200 remains in contact with the extension plate 150. In case of an emergency, when a person applies external force to the operating part 211, the external force overcomes the pre-tightening force of the first elastic member 640, causing the first connecting arm 230 and the second connecting arm 240 to rotate. The first connecting arm 230 and the second connecting arm 240 respectively drive the two first concave cams 620 to rotate, and the two first concave cams 620 respectively push the two second concave cams 630 to move closer to each other along the axial direction of the first shaft 500, so that the first elastic member 640 is compressed. After the external force disappears, the first elastic element 640 resets. The elastic force of the first elastic element 640 causes the two second concave cams 630 to move away from each other along the axial direction of the first shaft 500. The two second concave cams 630 drive the two first concave cams 620 to rotate respectively. The two first concave cams 620 drive the first connecting arm 230 and the second connecting arm 240 to rotate respectively, so that the unlocking element 200 resets.

[0146] In some embodiments, reference is made to Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of another structure of the door handle assembly 2000 provided in an embodiment of this application. Figure 17 for Figure 16 The diagram shows the structure of the door handle assembly 2000 with the cover plate 30 in the open state. Figure 16 The cover plate 30 shown is in the closed state. Figure 17The cover plate 30 shown is in the open state. The handle component 100 has a handle groove 300 and a recess 10. The recess 10 is located on the outer surface 101. The recess 10 and the handle groove 300 are arranged at intervals, and the distance between the recess 10 and the opening side of the door 1100 is less than the distance between the handle groove 300 and the opening side of the door 1100. The door handle assembly 2000 also includes a second switch 20 and a cover plate 30. The second switch 20 is connected to the door. Optionally, the second switch 20 can be connected to the door via a mounting bracket 700. One end of the second switch 20 extends into the recess 10. The cover plate 30 is disposed in the recess 10 to cover the second switch 20, and the side of the cover plate 30 facing the recess 10 abuts against one end of the second switch 20.

[0147] Both the groove 10 and the cover plate 30 can be square. Alternatively, the groove 10 and the cover plate 30 can also be regular shapes such as circles, ovals or triangles, or they can be irregular shapes. This application does not impose any limitations on them.

[0148] The second switch 20 is an electronically controlled switch. It is an elastic element; when a person presses the cover plate 30, the force is transmitted through the cover plate 30 to the second switch 20. The second switch 20 deforms under pressure, causing its internal contacts to conduct and generate an unlocking signal, which is then sent to the controller. Upon receiving the unlocking signal, the controller sends a drive signal to the drive component. Upon receiving the drive signal, the drive component activates, moving the pull cable to unlock the door lock. The controller can be a vehicle controller or an auxiliary controller electrically connected to the vehicle controller. The drive component can be a motor or a cylinder, etc.

[0149] The opening side of the door 1100 refers to the side of the door 1100 that can be opened to allow people to enter the vehicle. Opposite to the opening side of the door 1100 is the connecting side of the door 1100, which is connected to the vehicle body by a hinge to prevent the door 1100 from falling off. The distance between the groove 10 and the opening side of the door 1100 is less than the distance between the handle groove 300 and the opening side of the door 1100. That is, the groove 10 is closer to the opening side of the door 1100 than the handle groove 300, so that the second switch 20 and the cover plate 30 located at the groove 10 are closer to the opening side of the door 1100. After pressing the cover plate 30, the door 1100 can be opened smoothly without any deviation. If the groove 10 is located on the side of the handle groove 300 away from the opening side of the door 1100, then the second switch 20 and the cover plate 30 located at the groove 10 will also be far from the opening side of the door 1100. After pressing the cover plate 30, one needs to move back a certain distance to avoid the door 1100 before the door 1100 can be opened smoothly. Therefore, placing the groove 10 between the handle groove 300 and the opening side of the door 1100 can increase ease of use and improve the user experience.

[0150] For example, the surface of the cover plate 30 facing away from the groove 10 is flush with the outer surface 101 of the handle member 100. The second switch 20 supports the cover plate 30 so that the outer surface of the cover plate 30 is flush with the outer surface 101 of the handle member 100, which can increase the aesthetics of the door handle assembly 2000.

[0151] In some embodiments, reference is made to Figure 17 The door handle assembly 2000 also includes a mechanical lock cylinder 40, which is connected to the door. Optionally, the mechanical lock cylinder 40 can be connected to the door via a mounting bracket 700, and one end of the mechanical lock cylinder 40 with a lock hole extends into the recess 10. The cover plate 30 also covers the mechanical lock cylinder 40. When the vehicle 1000's small battery is not de-energized, the user can use the remote key to unlock the vehicle 1000's central locking system, and then open the door 1100 using the first switch 400 or the second switch 20. Of course, in an emergency, the door 1100 can be opened using the aforementioned unlocking device 200. That is, before unlocking the door lock using the first switch 400, the second switch 20, or the unlocking device 200, the central locking system must first be unlocked using the remote key. When the vehicle 1000's small battery loses power, the user can open the cover 30, insert the mechanical key into the lock cylinder 40 to disengage the vehicle 1000's central locking system, and then operate the unlocking mechanism 211 from the handle slot 300 to unlock the door lock, allowing the door 1100 to be opened. In other words, when the vehicle 1000's small battery loses power, the central locking system can be disengaged first using the mechanical key, and then the door locks can be unlocked using the unlocking mechanism 200.

[0152] In some embodiments, reference is made to Figure 17 and Figure 18 , Figure 18 for Figure 16 The diagram shows a partial structural schematic of the door handle assembly 2000. A second connecting part 31 is connected to the side of the cover plate 30 facing the groove 10. The second connecting part 31 extends into the interior of the door 1100 and is rotatably connected to the door. Optionally, the second connecting part 31 can be rotatably connected to the door via a mounting base 700. For example, the mounting base can be provided with a third shaft 50, and the second connecting part 31 is rotatably connected to the third shaft 50. A handle groove 32 is provided at the bottom of the cover plate 30. When the cover plate 30 needs to be opened, the user can apply force to the cover plate 30 from the handle groove 32, causing the second connecting part 31 to rotate around the third shaft 50, and the cover plate 30 to flip upwards, thereby exposing the mechanical lock cylinder 40 within the groove 10. The cover plate 30 is rotatably connected to the door, allowing for easy opening of the cover plate 30. Even after opening, the cover plate 30 remains connected to the door, preventing it from falling off.

[0153] Alternatively, the cover plate 30 can be connected to the groove 10 via a snap-fit ​​and slot structure.

[0154] In some embodiments, reference is made to Figure 17 and Figure 18 The door handle assembly 2000 also includes a second reset member 60, which is sleeved on the third shaft 50. The second reset member 60 is used to reset the cover plate 30. The second reset member 60 has a pre-tightening force, which keeps the cover plate 30 in a closed state. The pre-tightening force needs to be less than the supporting force of the second switch 20 on the cover plate 30 to avoid excessive pre-tightening force, which could cause the second switch 20 to be squeezed and deformed. It also keeps the outer surface of the cover plate 30 flush with the outer surface 101 of the handle assembly 100, improving the aesthetics of the handle assembly 100. When it is necessary to open the cover plate 30, a person can apply force to the cover plate 30 to overcome the pre-tightening force, causing the second connecting part 31 to rotate around the third shaft 50. The cover plate 30 and the second connecting part 31 rotate synchronously, allowing the cover plate 30 to open. After the person releases the cover plate 30, the second reset member 60 gradually resets, causing the second connecting part 31 to rotate in the opposite direction, thereby resetting the cover plate 30.

[0155] In one possible implementation, refer to Figure 17 and Figure 18 The second reset member 60 is a second torsion spring 61, which is sleeved on the third shaft 50. One torsion foot of the second torsion spring 61 abuts against the second connecting part 31, and the other torsion foot of the second torsion spring 61 abuts against the mounting base 700.

[0156] For example, the second connecting part 31 includes a third connecting arm 33 and a fourth connecting arm 34. One end of the third connecting arm 33 and one end of the fourth connecting arm 34 are respectively sleeved on the third shaft 50, and the second torsion spring 61 is located between the third connecting arm 33 and the fourth connecting arm 34.

[0157] The second torsion spring 61 includes a third sub-torsion spring 62 and a fourth sub-torsion spring 63. One torsion foot of the third sub-torsion spring 62 abuts against the third connecting arm 33, and one torsion foot of the fourth sub-torsion spring 63 abuts against the fourth connecting arm 34. The other torsion foot of the third sub-torsion spring 62 and the other torsion foot of the fourth torsion spring 63 are fixedly connected to form a hook portion, and the hook portion is fixedly connected to the mounting base 700.

[0158] The third connecting arm 33 and the fourth connecting arm 34 can have the same structure. Both the third connecting arm 33 and the fourth connecting arm 34 are curved rods. One end of the third connecting arm 33 and the fourth connecting arm 34 are rotatably connected to the third shaft 50, and the other end of the third connecting arm 33 and the fourth connecting arm 34 extend into the groove 10 and are connected to the cover plate 30.

[0159] In another possible implementation, the second connecting portion 31 includes a third connecting arm 33 and a fourth connecting arm 34. One end of the third connecting arm 33 and one end of the fourth connecting arm 34 are respectively sleeved on the third shaft 50. The second resetting member 60 includes two third concave cams, two fourth concave cams, and a second elastic member. The two third concave cams, two fourth concave cams, and the second elastic member are all sleeved on the first shaft 500 and are all located between the third connecting arm 33 and the fourth connecting arm 34. One of the third concave cams is fixed to the side of the third connecting arm 33 facing the fourth connecting arm 34, and the other third concave cam is fixed to the side of the fourth connecting arm 34 facing the third connecting arm 33. The two fourth concave cams respectively engage with the two third concave cams. The second elastic member is located between the two fourth concave cams, and both ends of the second elastic member abut against the two fourth concave cams respectively.

[0160] The working principle of the second reset member 60 with the two structures can be referred to the working principle of the first reset member 600 with the two structures mentioned above.

[0161] When the door handle assembly 2000 is in normal opening mode, the door 1100 can be unlocked via either the first switch 400 or the second switch 20. In case of a power outage requiring emergency opening, the door 1100 can be quickly opened via the mechanical backup inside the handle assembly 100; this mechanical backup refers to the unlocking component 200. Additionally, in the event of a power failure, the door 1100 can be unlocked via the mechanical lock cylinder 40 located beneath the cover plate 30.

[0162] In some embodiments, reference is made to Figure 19 , Figure 19 for Figure 16 The diagram shows another partial structural schematic of the door handle assembly 2000. A sealing ring is provided in the groove 10, and the edge of the cover plate 30 facing the groove 10 abuts against the sealing ring. The sealing ring can be a rubber ring, which can increase the sealing performance and prevent foreign objects from entering the groove 10 and affecting the safety of the vehicle 1000. In addition, the sealing ring can also prevent vibration and abnormal noise.

[0163] The above describes the basic architecture of the solution and provides several possible implementation methods, which can be combined without mutual exclusion. For ease of understanding, the following section will combine... Figures 20-22 Several examples of combinations are presented below. The solutions in these examples can also be combined without mutual exclusion. The structure and connection relationships of the various components in this embodiment can be referenced from the above-described infrastructure.

[0164] In this embodiment, reference Figure 20 and Figure 21 , Figure 20 This is a structural schematic diagram of a door handle assembly 2000 provided in another embodiment of this application. Figure 21This is a schematic diagram of the split structure of a door handle assembly 2000 according to another embodiment of this application. The door handle assembly 2000 includes a handle component 100 and an unlocking component 200. The handle component 100 includes a panel 110 and a surrounding component 120. The unlocking component 200 includes a first driving component 210 and a second driving component 220. The first driving component 210 includes an operating part 211, a first connecting part 216, and a first driving swing arm 217. The second driving component 220 includes a body part 221, a second driving swing arm 222, and an unlocking swing arm 223. The handle component 100 and the unlocking component 200 form at least one side of the handle groove 300. A first switch 400 is provided on the side of the unlocking component 200 facing away from the handle groove 300.

[0165] The handle 100 and the unlocking component 200 can be connected to the door via the mounting base 700. Optionally, the mounting base 700 is provided with a first shaft 500 and a second shaft 510. The first connecting part 216 and the main body part 221 are respectively rotatably connected to the first shaft 500 and the second shaft 510. The first shaft 500 is fitted with a first reset component 600.

[0166] Please refer to the above. Figure 22 , Figure 22 A schematic diagram illustrating the state changes of the door handle assembly 2000 provided in this embodiment of the application. Figure 22 Image (a) shows the unlocking element 200 in a locked state. Figure 22 (b) shows the unlocking element 200 in the unlocked state. Under normal circumstances, a person can open the door 1100 by reaching into the handle slot 300 and touching the first switch 400. In an emergency, a person can reach into the handle slot 300 and pull the operating part 211 to overcome the pre-tightening force of the first reset element 600. This causes the operating part 211 to drive the first connecting part 216 to rotate around the first shaft 500. The first drive swing arm 217 and the first connecting part 216 rotate synchronously. The first drive swing arm 217 drives the second drive swing arm 222 to rotate. The main body 221 and the unlocking swing arm 223 rotate synchronously with the second drive swing arm 222, causing the unlocking swing arm 223 to move the pull cable, thereby unlocking the door lock. After the operator releases the operating part 211, the first reset member 600 resets, the first connecting part 216 starts to rotate in the opposite direction, and at the same time the operating part 211 and the first drive swing arm 217 also rotate in the opposite direction to reset. The first drive swing arm 217 can drive the second drive swing arm 222 to reset, and the main body 221 and the unlocking swing arm 223 reset synchronously with the second drive swing arm 222.

[0167] refer to Figure 21The handle 100 is also provided with a groove 10. The door handle assembly 2000 also includes a second switch 20, a cover plate 30 and a mechanical lock cylinder 40. The core lock cylinder and the second switch 20 are both located inside the door 1100, and one end of the mechanical lock cylinder 40 and the second switch 20 both extend into the groove 10. The cover plate 30 is located in the groove 10 and covers the mechanical lock cylinder 40 and the second switch 20. The surface of the cover plate 30 facing the groove 10 abuts against the second switch 20.

[0168] The mounting base 700 also includes a third shaft 50. A second connecting part 31 is connected to the cover plate 30, and the second connecting part 31 is rotatably connected to the third shaft 50. A second reset member 60 is fitted onto the third shaft 50. Under normal circumstances, the user can also press the cover plate 30, which transmits force to the second switch 20, causing the second switch 20 to unlock the door lock. Additionally, when the vehicle's small battery fails, the user can overcome the resistance of the second reset member 60 to open the cover plate 30 and use the mechanical key to insert into the lock cylinder 40 to unlock the central locking system. When the user releases the cover plate 30, the second reset member 60 resets, which in turn resets the cover plate 30.
