Description

Technical Field

[0001] The invention relates to a door handle installation structure and also to a lock using the door handle installation structure. Background Art

[0002] The existing handle is usually installed on the lock or door body through a panel, and the panel is usually provided with a through hole, through which the rotating shaft of the handle is inserted into the panel to position the handle on the panel. Figure 1 As shown, the invention with patent announcement number CN110230428A discloses a handle reversing device, specifically, including a housing 101 and a handle 102, wherein the handle 102 includes a mounting end 121 and a grip section 122, and the mounting end 121 passes through the mounting hole of the housing 101 and enters the interior of the housing 101, and is connected or assembled with other parts inside the housing. This traditional mechanical lock installation structure is obviously too simple and unsuitable for the development requirements of modern technology, especially intelligent integrated technology. Summary of the invention

[0003] The present invention aims to provide a lock that is beautiful in appearance and suitable for modern intelligent development, especially a door handle installation structure for the lock. In the current design requirements, it is necessary to solve the problem of reliable installation and positioning of the door handle, the problem of facilitating the reversal of the door handle, the problem of integrating intelligent technology with traditional mechanical locks, etc. For this purpose, the present invention proposes a novel door handle installation structure, characterized in that it includes a door handle and a positioning seat, the positioning seat includes an outer shell, the outer shell includes an outer shell wall arranged along the axial direction and a radial wall arranged radially, and the radial wall is provided with a barrel bottom central hole; the positioning seat also includes a door handle transmission member arranged in the outer shell, and the door handle transmission member is used to transmit the rotational power of the door handle; the door handle transmission member includes a shaft and a connecting portion connected to the front of the shaft, the shaft located at the rear is rotatably arranged on the barrel bottom central hole, and the connecting portion located at the front is connected to the door handle, the outer shell wall and the door handle are wedged with each other, and a wire passage is arranged in the outer shell.

[0004] Among them, the positioning seat is a component independent of the door handle but can be combined with the door handle. The positioning seat provides an installation and positioning basis for the door handle mounting structure. With the help of the positioning seat, not only can the door handle be positioned, but also the rotational power of the door handle can be transmitted to the lock body of the lock, etc.

[0005] Secondly, a wire-passing channel is arranged in the outer shell of the positioning seat, so as to provide convenient conditions for transmitting electrical signals to realize the integration of intelligence and machinery. The lock body includes a lock tongue and a shift block capable of driving the lock tongue to move, and the door handle transmission member is connected to the shift block through a square iron member. The door handle is used to drive the lock tongue to retract or extend with the help of the shift block when the door handle is rotated.

[0006] The shaft and the connection part are respectively one of the components of the door handle transmission part, but the relative functional use is different. The connection part is used to detachably mechanically connect the door handle, and is used to transmit the rotational power of the door handle to the shaft. The connection part can be completely arranged in the outer shell wall of the positioning seat, so that the door handle partially extends into the outer shell wall of the outer shell and connects with the connection part; the connection part can also slightly protrude from the front end of the outer shell wall and connect with the door handle; the connection part can also be arranged in the outer shell wall of the outer shell and the front end face is flush with the front end face of the outer shell wall of the positioning seat.

[0007] Wherein, the shaft portion is used to position the door handle transmission component and transmit the rotational power of the door handle.

[0008] The shaft is rotatably arranged on the central hole of the barrel bottom of the radial wall, which defines the positioning connection relationship between the shaft and the radial wall. The shaft and the radial wall can be connected by either a sliding bearing or a rolling bearing.

[0009] Among them, the shell wall and the door handle are wedged with each other. This feature defines the relative assembly relationship between the shell wall and the door handle; first, since the door handle is connected to the door handle transmission member, the door handle can rotate relative to the shell wall, that is, the shell wall and the door handle are wedged with each other, which does not mean that they cannot rotate relative to each other; secondly, it is defined that the shell wall and the door handle are relatively close to each other and even partially overlap each other, and the shapes at the close positions are also adapted to each other but are not fixedly connected to each other. The shell and the door handle include at least the following types of wedged assembly relationships:

[0010] In the first kind of mutually wedging assembly relationship, the front end surface of the outer shell wall facing the door handle and the end surface of the door handle facing the outer shell are parallel to each other with a small gap, so during the rotation of the door handle, the door handle will not be affected by the outer shell wall.

[0011] The second kind of mutually wedging assembly relationship, the outer shell wall partially extends into the door handle, for example, the door handle is provided with a stop-shaped air avoidance hole corresponding to the shape of the outer shell wall, the front end of the outer shell wall extends into the stop-shaped air avoidance hole, and the gap between the outer wall of the outer shell wall and the inner wall of the stop-shaped air avoidance hole is very small, and the shapes of the two are matched, so that the door handle will not be blocked by the outer shell wall during the rotation process.

[0012] The third kind of mutually wedging assembly relationship, the door handle partially extends into the outer shell, for example, the door handle to be mentioned below includes a handle coupling part and a gripping part, the handle coupling part is provided with a stop-shaped step, the stop-shaped step extends into the outer shell wall, the stop-shaped step of the handle coupling part matches the inner wall shape of the outer shell wall, and the gap between the two is very small, the stop-shaped step of the handle coupling part extends into the outer shell wall and does not affect the rotation of the door handle.

[0013] Among them, the outer shell is provided with a wire-passing channel, which defines that the outer shell wall and radial wall of the outer shell are respectively provided with wire-passing channels, and the wire-passing channel is used to arrange signal lines for transmitting electrical signals. Part of the wire-passing channel can be arranged in the door handle transmission part, or in the free space between the outer shell wall and the door handle transmission part. In short, the space arranged in the outer shell that allows the signal line (including the control signal line or the power signal line) to pass through is the wire-passing channel.

[0014] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are:

[0015] First, since the outer shell includes an outer shell wall arranged axially and a radial wall arranged radially, a space for accommodating the door handle transmission member can be formed in the outer shell. Secondly, since the outer shell wall is arranged axially, not only can the door handle be relatively far away from the outer surface of the door leaf when installed and used, but also the aesthetics of the entire installation structure is improved. In addition, since a wire passage is provided in the outer shell, it not only facilitates the arrangement of the signal line but also greatly improves the intelligent integration of the lock.

[0016] Second, since the radial wall is provided with a barrel bottom central hole, the shaft is rotatably provided on the barrel bottom central hole, thereby greatly improving the positioning strength of the door handle transmission member.

[0017] Third, since the shell wall and the door handle are wedged with each other, they can move relative to each other with a small gap, which greatly improves the dustproof ability and has a beautiful appearance, and does not expose the related components installed inside them. In particular, when a stopper matching structure is adopted between the shell wall and the door handle, the door handle can also achieve auxiliary radial positioning and axial positioning with the help of the stopper structure, greatly improving the rotation stability of the door handle.

[0018] In order to realize the axial positioning of the door handle transmission member relative to the wall of the positioning seat housing, a further technical solution may be to provide a retaining spring on the shaft of the door handle transmission member, and the retaining spring and the door handle are disposed on both sides of the radial wall relative to each other, and the retaining spring is used to position the door handle transmission member in the axial direction so that it does not axially escape from the radial wall. In this solution, the shaft of the door handle transmission member is configured in a step shape, and the raised portion of the step is located in front of the radial wall, so that the shaft can be positioned by the step so that it does not move axially backward. That is, the retaining spring and the raised portion of the step are disposed on both sides of the radial wall.

[0019] A further technical solution may be that a bearing is provided between the shaft and the central hole of the barrel bottom, and the shaft is rotatably provided on the central hole of the barrel bottom through the bearing. The bearing may be a sliding bearing or a ball bearing.

[0020] In order to facilitate the transportation, installation and disassembly of the door handle installation structure, a further technical solution may be that the door handle is detachably connected to the connecting portion by screws.

[0021] In order to realize that the door handle transmission part transmits the rotational power to the shift block of the lock body, and then realizes that the lock tongue of the lock can be driven to retract or extend when the door handle is rotated, a further technical solution can also be that an axial central square hole is also provided at the rear end of the door handle transmission part, and the axial central square hole is used to connect the square iron piece. Among them, one end of the square iron piece is connected to the axial central square hole provided at the rear end of the door handle transmission part, and the other end is connected to the shift block on the lock body, so that the door handle transmission part is connected to the shift block of the lock body, and then the rotational power of the door handle is transmitted to the shift block of the lock body.

[0022] In order to realize the rotational reset of the door handle, a further technical solution may also include a reset torsion spring arranged in the outer shell, the coil of the reset torsion spring is sleeved on the shaft and arranged between the radial wall and the connecting portion, the connecting portion is provided with a protrusion extending toward the reset torsion spring, the protrusion rests on the torsion arm of the reset torsion spring, and the reset torsion spring is used to drive the door handle transmission member to reset. In this way, when the door handle is rotated, the door handle drives the connecting portion to rotate, and then drives the protrusion on the connecting portion to rotate. During the rotation process, the protrusion drives one of the torsion arms of the reset torsion spring to rotate, so that the reset spring deforms to generate a rebound force opposite to the rotation direction of the door handle. When the door handle is released, the door handle rotates and resets under the action of the rebound force. For example, the reset torsion spring is arranged on the torsion spring cavity, and an opening with a certain angle is arranged on one side of the torsion spring cavity, and the two torsion arms on the reset torsion spring are respectively located at the two ends of the opening, and the protrusion is inserted into one side of one of the torsion arms of the reset torsion spring. When the door handle rotates, the protrusion is driven to move, and the protrusion acts on the torsion arm located on one side of the protrusion, so that the above-mentioned torsion arm rotates in the opening, while the other torsion arm is restricted to stay in place due to the limiting effect of the opening, that is, the two torsion arms approach each other in the opening, so that the reset torsion spring is deformed and generates a rebound force in the opposite direction of rotation of the door handle. When the driving force driving the connecting part to rotate disappears, under the action of the rebound force, the two torsion arms move away from each other in the opening, and the torsion arm located on one side of the protrusion drives the protrusion to reset, and then drives the door handle transmission member and the door handle to reset.

[0023] A further technical solution may be that a barrel bottom side hole is provided on the radial wall, the barrel bottom side hole is located at the side of the barrel bottom central hole, the barrel bottom side hole constitutes part of the wire passing channel, and the barrel bottom side hole is used to allow the control signal line to pass through.

[0024] Among them, the side hole on the bottom of the barrel, on the one hand, is a part of the wire passage and has the same function as the wire passage, that is, it is used to allow the control signal line to pass through or to arrange the signal line for transmitting electrical signals. On the other hand, since the wire passage is arranged in the outer shell, and part of the wire passage can be set in the door handle transmission member, and can also be set in the empty space between the outer shell wall and the door handle transmission member, and because the door handle transmission member can rotate in the outer shell, the side hole on the bottom of the barrel is also used to ensure that the signal line arranged in the side hole on the bottom of the barrel and other parts of the wire passage does not affect the rotation of the door handle transmission member in the positioning seat, and to ensure that the control signal line will not be squeezed or otherwise damaged or affected during the rotation of the door handle transmission member in the outer shell, that is, during the rotation of the door handle transmission member, the side hole on the bottom of the barrel always remains connected to the other parts of the wire passage, and the connected space can ensure the safe passage of the control signal line.

[0025] A further technical solution may be that the door handle includes a handle combining portion for connecting to the door handle transmission component and a gripping portion for hand holding, and the handle combining portion is provided with at least two connecting through holes, the connecting through holes are used for allowing screws connecting the door handle transmission component to pass through, and the connecting through holes are arranged in positions that can ensure that the handle combining portion can be respectively installed on the door handle transmission component in a reversing manner.

[0026] The handle joint is essentially used to connect with the door handle transmission member, and is rotationally connected with the positioning seat through the door handle transmission member. Therefore, the screw is essentially used to connect the door handle transmission member and the handle joint together.

[0027] The grip portion is the area of ​​the door handle provided for the user to hold so as to conveniently control the movement of the door handle.

[0028] Wherein, the connecting through hole is used to cooperate with the screw to connect the handle combination part with the door handle transmission component. Accordingly, the door handle transmission component is provided with screw holes corresponding to the connecting through holes one by one. Further, the screw holes are provided on the connecting part of the door handle transmission component.

[0029] Wherein, the connecting through-holes are arranged at positions that can ensure that the handle joint is respectively installed on the positioning seat in a reversing manner. This feature defines that before and after the handle joint is reversed, the connecting through-holes on the handle joint can still respectively correspond to the screws connected to the door handle transmission member. For example, the connecting through-holes include two, which are symmetrically arranged on the handle joint and located on the central axis of the handle joint. Similarly, the screw holes include two, which are symmetrically arranged on the connection part and located on the central axis of the connection part. The spacing between the two connecting through-holes is the same as the spacing between the two screw holes. Before and after the handle joint is reversed, the connecting through-holes still correspond to the screw holes and can be connected by the screws to achieve the connection between the handle joint and the door handle transmission member.

[0030] A further technical solution may be that, in order to achieve the reversal of the door handle, the handle coupling portion has two coupling surfaces, namely a first coupling surface and a second coupling surface, the first coupling surface is used for the door handle to face the positioning seat when it is connected to the door handle transmission member in a first direction, and the second coupling surface is used for the door handle to face the positioning seat when it is connected to the door handle transmission member in a second direction, and the first direction and the second direction are reversed and flipped 180° with each other; a first stop is provided on the first coupling surface, and a second stop is provided on the second coupling surface, and the front end edge of the outer shell wall can be wedged and configured on the first stop and the second stop respectively when the door handle is installed in different directions.

[0031] The first direction and the second direction are reversed by 180°, which is actually a mirror image of each other, thereby achieving the reversal of the door handle.

[0032] Among them, a first stop is provided on the first joint surface, and a second stop is provided on the second joint surface, and the front end edge of the shell wall can be respectively wedged and configured on the first stop and the second stop when the door handle is installed in different directions. This feature can also be interpreted as the shape, size, etc. of the first stop and the second stop are respectively wedged with the front end edge of the shell wall, so as to ensure that they have the same or similar wedging degree after reversing.

[0033] In order to realize the integration of intelligent technology and traditional mechanical locks, a further technical solution may also include a sensing module installed on the outer side of the handle joint, the sensing module is used to receive the user's verification command information, and the sensing module can be respectively wedged and configured on the first stop and the second stop when the door handle is installed in different directions.

[0034] The touch module is used to receive the user's verification instruction information, which defines that the touch module has a component for receiving the user's verification instruction information, and the user can input the verification instruction information through the component for receiving the user's verification instruction information. For example, a verification device for verifying the verification instruction information can be set on the lock body or door leaf, and the touch module can be connected to the verification device through a signal line and transmit the verification instruction information. When the verification device is used to verify that the verification instruction information is correct, the verification device controls the lock to unlock, so that the user can unlock the lock by turning the door handle.

[0035] The verification instruction information may be a fingerprint or a password. When the user inputs the correct verification instruction information, the verification device controls the lock to unlock, so that the user can unlock the lock by turning the door handle.

[0036] A further technical solution may be that the connecting portion has a accommodating cavity, a battery box is arranged in the accommodating cavity, the battery box is used to accommodate batteries, and the door handle is connected to the cavity wall of the accommodating cavity and axially presses the battery box.

[0037] The door handle is connected to the cavity wall of the accommodating cavity and axially presses the battery box. This feature defines that when the door handle is connected to the connecting portion, the door handle cooperates with the accommodating cavity to limit the position of the battery box, but when the door handle is removed from the connecting portion, the battery box can be taken out of the accommodating cavity. In this way, the positioning and removal of the battery box in the connecting portion are respectively achieved through the installation and removal of the door handle.

[0038] A further technical solution may also be that the handle coupling portion is provided with a handle battery hole for allowing the battery to pass through, and the outer side edge of the handle coupling portion is provided with a battery cover, and the battery cover can be respectively wedged and configured on the first stop and the second stop when the door handle is installed in different directions and cover the handle battery hole.

[0039] Among them, the handle battery hole is used for when the door handle is installed on the connecting part, the battery box is fixed by the door handle inside the accommodating cavity of the connecting part, and the battery can still be taken out or put in through the handle battery hole.

[0040] The battery cover is used to be able to be respectively engaged with the first stop and the second stop when the door handle is installed in different directions, and to cover the battery hole of the handle; and is also used to cooperate with the battery box to form a connection between the battery inside the battery box, and to supply power to the electrical components inside the door handle installation structure or the lock through wires. When the battery needs to be replaced, it is only necessary to remove the battery cover from the door handle, and then take the battery out of the battery box through the handle battery hole on the door handle and replace it, and then reinstall the battery cover on the door handle to re-establish the battery connection state.

[0041] The invention also discloses a lock device using the above-mentioned door handle mounting structure, including a lock body, the lock body including a lock tongue and a shift block capable of driving the lock tongue to move, and also including the above-mentioned door handle mounting structure, the door handle transmission member is used to connect the shift block through a square iron member, and the door handle is used to drive the lock tongue to be retracted or extended with the help of the shift block when the door handle is rotated.

[0042] Since the present invention has the above characteristics and advantages, it can be widely applied to various locks and door handle installation structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following is combined with the attached drawings Figure 2-8 The door handle installation structure using the technical solution of the present invention and the structure of the lock used therein are further described.

[0052] In this embodiment, the door handle mounting structure is used for positioning and mounting the inner door handle and the outer door handle respectively. The inner door handle mounting structure for mounting the inner door handle and the outer door handle mounting structure for mounting the outer door handle are basically the same in structure. Therefore, the door handle mounting structure of the outer door handle is mainly used as an example for explanation.

[0053] like Figures 2 to 5 , Figure 8 As shown, the outer door handle installation structure for installing the outer door handle includes an outer door handle 1 and an outer door handle positioning seat 2.

[0054] Among them, the outer door handle positioning seat 2 is a component that is independent of the outer door handle 1 but can be combined with the outer door handle 1. The outer door handle positioning seat 2 provides an installation and positioning basis for the door handle mounting structure of the outer door handle 1. With the help of the outer door handle positioning seat 2, not only can the outer door handle 1 be positioned, but also the rotational power of the outer door handle 1 can be transmitted to the lock body 31 of the lock.

[0055] like Figure 2-5 and Figure 8As shown, the outer door handle positioning seat 2 includes an outer shell 4 and an outer door handle transmission member 5 arranged in the outer shell 4. The outer shell 4 includes an outer shell wall 41 arranged axially and a radial wall 42 arranged radially. The radial wall 42 is provided with a barrel bottom central hole 43. The outer door handle transmission member 5 includes an outer door handle shaft 51 and an outer door handle connecting portion 52 connected to the front of the outer door handle shaft 51. The outer door handle shaft 51 located at the rear is rotatably arranged on the barrel bottom central hole 43, and the outer door handle connecting portion 52 located at the front is connected to the outer door handle 1. The outer door handle shaft 51 and the outer door handle connecting portion 52 are respectively one of the components of the outer door handle transmission member 5, but the relative functional use division is different. The outer door handle connecting portion 52 is used to detachably mechanically connect the outer door handle 1, and is used to transmit the rotational power of the outer door handle 1 to the outer door handle shaft 51. In this embodiment, the outer door handle connection portion 52 slightly protrudes from the front end of the outer shell wall 41 and is connected to the outer door handle 1. In other embodiments, in order to achieve the connection between the outer door handle connection portion 52 and the outer door handle 1, the outer door handle connection portion 52 can be completely arranged in the outer shell wall 41, so that the outer door handle 1 partially extends into the outer shell wall 41 and is connected to the outer door handle connection portion 52; the outer door handle connection portion 52 can also be arranged in the outer shell wall 41 and the front end face is flush with the front end face of the outer shell wall 41 of the outer door handle positioning seat 2.

[0056] In order to realize that the outer door handle transmission member 5 transmits the rotational power to the shift block of the lock body 31, and further realize that the lock tongue 311 of the lock can be driven to retract or extend when the outer door handle 1 is rotated, an axial central square hole 513 is also provided at the rear end of the outer door handle transmission member 5, and a square iron piece 514 is connected to the axial central square hole 513. Among them, one end of the square iron piece 514 is connected to the axial central square hole 513 provided at the rear end of the outer door handle transmission member 5, and the other end is connected to the shift block on the lock body 31 (located in the lock body 31, not shown in the figure), so that the outer door handle transmission member 5 is connected to the shift block of the lock body 31, and further realizes the transmission of the rotational power of the outer door handle 1 to the shift block of the lock body 31. In this embodiment, a spring 515 is further provided in the axial central square hole 513, one end of the spring 515 is against the square iron piece 514, and the other end is against the inner bottom surface of the axial central square hole 513, and when the external door handle mounting structure is installed on the lock body 31, the spring 515 is compressed and pushes the square iron piece 514 toward the shift block.

[0057] In order to realize the axial positioning of the outer door handle 1 relative to the outer door handle positioning seat 2, a retaining spring 511 and a step 516 are provided on the outer door handle shaft 51 of the outer door handle transmission member 5. The retaining spring 511 and the step 516 are disposed on both sides of the radial wall 42 in a relative manner. The retaining spring 511 is sleeved on the outer door handle shaft 51 and rotates with the outer door handle shaft 51. The retaining spring 511 and the step 516 are used to axially position the outer door handle transmission member 5. Furthermore, a gasket 512 sleeved on the outer door handle shaft 51 is provided between the retaining spring 511 and the radial wall 42 to prevent the retaining spring 511 from scratching the radial wall 42 during the process of rotating with the shaft 42.

[0058] Specifically, the central hole 43 on the barrel bottom on the radial wall body 42 is set as a bearing cavity for accommodating a rolling bearing 45. The rolling bearing 45 is accommodated in the bearing cavity and connected to the outer door handle shaft 51, thereby realizing the rotation of the outer door handle shaft 51 relative to the outer shell 4. Since the outer door handle connecting portion 52 is used to detachably mechanically connect the outer door handle 1 and transmit the rotational power of the outer door handle 1 to the outer door handle shaft 51, the rotation of the outer door handle 1 relative to the outer door handle positioning seat 2 is realized. The rolling bearing 45 can also provide a radial positioning effect for the rotation of the outer door handle 1 on the outer door handle positioning seat 2.

[0059] Furthermore, in order to realize the rotational reset of the outer door handle 1, as Figure 3As shown, a return torsion spring 46 is provided in the shell wall body 41, and the ring body 461 of the return torsion spring 46 is sleeved on the outer door handle shaft portion 51 and arranged between the radial wall body 42 and the outer door handle connecting portion 52, and a protrusion 531 extending toward the return torsion spring 46 is provided on the outer door handle connecting portion 52, and the return torsion spring 46 is arranged in the torsion spring cavity 44 on the radial wall body 42, and an opening 441 with a certain angle is provided on one side of the torsion spring cavity 44, and two torsion arms 462A and 462B on the return torsion spring 46 are respectively and correspondingly located at two ends of the opening 441, and the protrusion 531 is inserted between the torsion arms 462A and 462B of the return torsion spring 46, and is located on one side of one of the torsion arms 462A, when the outer door handle 1 The protrusion 531 rotates and moves, and the protrusion 531 acts on the torsion arm 462A located on one side of the protrusion 531, so that the torsion arm 462A rotates in the opening 441, while the other torsion arm 462B is restricted in place due to the limiting effect of the opening 441, that is, the two torsion arms 462A and 462B approach each other in the opening 441, so that the reset torsion spring 46 is deformed and generates a rebound force in the opposite direction of the rotation of the outer door handle 1. When the driving force driving the outer door handle 1 to rotate disappears, under the action of the rebound force, the two torsion arms 462A and 462B move away from each other in the opening 441, and the torsion arm located on one side of the protrusion 531 drives the protrusion 531 to reset, and then drives the outer door handle transmission member 5 to reset.

[0060] In this embodiment, a wire passage is arranged in the outer shell 4 for arranging a signal line for transmitting an electrical signal. Specifically, a wire passage hole 47 is arranged on the outer door handle connecting portion 52, and the wire passage hole 47 constitutes a part of the wire passage. In other parts, the wire passage is arranged in the empty space between the outer shell wall 41 and the outer door handle transmission member 5.

[0061] The radial wall 42 is provided with a barrel bottom side hole 48, the barrel bottom side hole 48 is located at the side of the barrel bottom central hole 43, the barrel bottom side hole 48 is used to allow the control signal line to pass through, and the barrel bottom side hole 48 is also a part of the wire passage. In this way, the wire passage hole 47, the barrel bottom side hole 48 and the empty space between the shell wall 41 and the outer door handle transmission member 5 together constitute the wire passage, which can ensure that the control signal line passes through safely, provide convenience for arranging the signal line and provide convenient structural conditions for greatly improving the intelligent integration of the lock. It should also be noted that the setting of the barrel bottom side hole 48 should ensure that the signal line arranged in the barrel bottom side hole 48 and other wire-passing channels does not affect the rotation of the outer door handle transmission component 5 in the outer door handle positioning seat 2, and ensure that the signal line will not be squeezed or otherwise damaged or affected during the rotation of the outer door handle transmission component 5 in the outer door handle positioning seat 2, that is, during the rotation of the outer door handle transmission component 5, the barrel bottom side hole 48 always remains connected to other parts of the wire-passing channel, and the space connecting the barrel bottom side hole 48 and the wire-passing channel can ensure the safe passage of the signal line.

[0062] In addition, the outer door handle 1 includes a handle coupling portion 11 for connecting to the outer door handle transmission member 5 and a hand grip portion 12 for hand gripping. The handle coupling portion 11 is circular as a whole and has two coupling surfaces, namely a first coupling surface 11A and a second coupling surface 11B. The first coupling surface 11A is used for the outer door handle 1 to face the outer door handle positioning seat 2 when it is connected to the outer door handle transmission member 5 in a first direction, and the second coupling surface 11B is used for the door handle to face the outer door handle positioning seat 2 when it is connected to the outer door handle transmission member 5 in a second direction.
