A type of door handle

Abstract

This application provides a door unlocking handle, including a rotating part and a base. A mechanical unlocking mechanism is connected to the rotating part. The rotating part is rotatably mounted on the base. The base has a mounting area, in which a contact box is installed. A contact piece is connected to one side of the contact box, and a micro switch for activating the electronic door unlocking mechanism or maintaining the door locked is connected to the contact box. When the door is closed, the rotating part applies pressure to the contact piece, causing the contact piece to contact the contact box, and the micro switch maintains the door locked. By providing a rotating part, initial rotation of the rotating part releases the contact between the rotating part and the contact assembly, thereby controlling the micro switch to open the door. If the micro switch fails, continued rotation of the rotating part causes it to drive the mechanical unlocking mechanism to open the door. This provides dual protection for opening the door, making driving safer, and the structure is simple and the manufacturing cost is low.

Description

Technical Field

[0001] This application relates to the technical field of automobile door locks, specifically to a door unlocking handle. Background Technology

[0002] With economic development and scientific progress, automobiles have gradually become an indispensable means of transportation, and sedans have become increasingly common in people's lives. Sedan cars are categorized into high-end and economy models based on their configurations. Since economy cars are cheaper, structural optimization is the most effective way to control costs. Most door lock handles require a handle mounting plate; the door lock handle and the mounting plate are then combined and installed onto the inner door panel. Currently, most car door locks only support either mechanical or electric unlocking. The inability to open the door when the electric unlocking fails poses a significant risk.

[0003] Car door locks that combine mechanical and electric unlocking have complex structures and high production costs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of this, this application provides a door handle that can double-protect the opening of the car door, making driving safer, and has a simple structure and low manufacturing cost.

[0006] (II) Technical Solution

[0007] To solve the aforementioned technical problem, this utility model provides a door handle, comprising:

[0008] A rotating part, on which a mechanical unlocking mechanism is connected;

[0009] A base, wherein the rotating part is rotatably mounted on the base;

[0010] The base is provided with an installation area, and a contact box is installed in the installation area. A contact piece is connected to one side of the contact box, and a micro switch for activating the electronic unlocking mechanism of the car door or maintaining the door locked state is connected to the contact box.

[0011] When the car door is closed, the rotating part applies pressure to the contact piece, causing the contact piece to abut against the contact box, and the micro switch maintains the car door locked.

[0012] When the rotating part is initially rotated in the first direction, the pressure applied to the contact piece by the rotating part decreases, thereby releasing the contact piece from contact with the contact box, and causing the micro switch to activate the electronic unlocking mechanism of the car door to open the car door;

[0013] Continue rotating the rotating part in the first direction, and the rotating part will pull the mechanical unlocking mechanism to open the car door.

[0014] In this solution, by setting a rotating part, the initial rotation of the rotating part removes the pressure on the contact piece, thereby canceling the contact between the contact piece and the contact box, thus controlling the micro switch to open the car door. When the micro switch fails, the rotating part continues to rotate, causing the rotating part to drive the mechanical unlocking mechanism to open the car door. This provides double protection for opening the car door, making driving safer, and the structure is simple and the manufacturing cost is low.

[0015] Preferably, the door handle includes a resistance feedback zone, which is located on the rotation path of the rotating part. When the rotating part rotates to the point where the micro switch activates the electronic door unlocking mechanism, the resistance feedback zone generates a sudden resistance.

[0016] In this solution, by setting a resistance feedback zone, the user can be notified that the electronically controlled microswitch of the door lock has been turned on.

[0017] As a further preferred embodiment, the resistance feedback zone consists of abutting protrusions and a first elastic element. The rotating part is provided with the protrusions, and the base is provided with the first elastic element. The first elastic element is disposed on the rotation path of the rotating part. When the rotating part rotates to the point where the micro switch activates the electronic unlocking mechanism of the car door, the first elastic element abuts against the protrusions and generates a sudden change in resistance.

[0018] In this design, by setting a protrusion and a first elastic element, the protrusion and the first elastic element come into contact during the rotation of the rotating part, and there is a clear pause, which can indicate to the user that the micro switch of the door lock's electronic control has been turned on.

[0019] Preferably, the contact box is provided with a stationary contact, and the contact piece includes an integrally formed connecting end and a deformable end. The connecting end is connected to the contact box, and the deformable end is provided with a moving contact. When the rotating part applies pressure to the deformable end, the moving contact abuts against the stationary contact to keep the door closed.

[0020] In this solution, by checking whether the rotating part applies pressure to the contact piece, and whether the moving contact of the contact piece abuts against the stationary contact of the contact box, a signal is transmitted to the contact box, which then controls the micro switch to open or close.

[0021] Preferably, a handle is provided on the side of the rotating part away from the micro switch, and a movable groove is provided on the base. The handle is located in the movable groove, and the handle and the rotating part form a latch.

[0022] In this design, the rotating part can be rotated more conveniently by setting a handle.

[0023] Preferably, the base is provided with a through groove, the rotating part is rotatably disposed in the through groove, the rotating part is provided with a pin, the two ends of the pin are respectively connected to the upper and lower end walls of the through groove, and a second elastic element is sleeved on the pin, the two ends of the second elastic element are respectively connected to the base and the rotating part.

[0024] In this solution, by setting a second elastic element, after the rotating part is rotated and the pulling force on the handle is released, the rotating part is reset under the action of the second elastic element and the car door is closed.

[0025] Preferably, the rotating part is provided with a first tooth, and a damper is provided on one side of the base, wherein the teeth on the damper mesh with the first tooth for transmission.

[0026] In this design, the rotational speed of the rotating part can be reduced by setting a damper, which can better protect the handle.

[0027] As a further preferred embodiment, a buffer pin is provided on the side wall of the through groove away from the handle portion.

[0028] In this design, the collision between the rotating part and the base can be reduced by setting buffer pins, thereby extending the service life of both.

[0029] As a further preferred embodiment, the base has a hand-clip area connected to the bottom of the movable groove.

[0030] In this design, the addition of a hand-operated area makes it easier for users to reach into the base and pull the handle to open the car door.

[0031] (III) Beneficial Effects

[0032] Compared with the prior art, the beneficial effects that this specification can achieve include at least the following:

[0033] (1) By setting a rotating part, the rotating part is initially rotated to remove the pressure of the rotating part on the contact piece, so that the contact piece and the contact box are canceled, thereby controlling the micro switch to open the car door. When the micro switch fails, the rotating part is rotated again, so that the rotating part drives the mechanical unlocking mechanism to open the car door. This can double guarantee the opening of the car door, making driving safer, and the structure is simple and the manufacturing cost is low.

[0034] (2) By setting a protrusion and a first elastic element, the protrusion and the first elastic element will come into contact during the rotation of the rotating part and there will be a clear pause, which can indicate to the user that the micro switch of the door lock is turned on.

[0035] (3) By whether the rotating part applies pressure to the contact piece, and whether the moving contact of the contact piece abuts against the stationary contact of the contact box, the signal is transmitted to the contact box, and the contact box controls the micro switch to open or close.

[0048] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0049] This application provides a door handle 1, including a rotating part 11 and a base 3, wherein a mechanical unlocking mechanism 2 is connected to the rotating part 11; the rotating part 11 is rotatably disposed on the base 3;

[0050] The base 3 is provided with an installation area 32, and a contact box 41 is installed in the installation area 32. A contact piece 42 is connected to one side of the contact box 41, and a micro switch 5 for activating the electronic unlocking mechanism of the car door or maintaining the locked state of the car door is connected to the contact box 41.

[0051] When the car door is closed, the rotating part 11 applies pressure to the contact piece 42, causing the contact piece 42 to abut against the contact box 41, and the micro switch 5 maintains the car door locked.

[0052] When the rotating part 11 is initially rotated in the first direction, the pressure applied by the rotating part 11 to the contact piece 42 decreases, thereby releasing the contact piece 42 from contact with the contact box 41, and causing the micro switch 5 to activate the electronic door unlocking mechanism to open the door.

[0053] Continue rotating the rotating part 11 in the first direction, and the rotating part 11 pulls the mechanical unlocking mechanism 2 to open the car door.

[0054] Furthermore, as a preferred embodiment, the door handle 1 includes a resistance feedback zone, which is disposed on the rotation path of the rotating part 11. When the rotating part 11 rotates to the point where the micro switch 5 activates the electronic door unlocking mechanism, the resistance feedback zone generates a sudden resistance.

[0055] Furthermore, as a preferred embodiment, the resistance feedback zone is composed of abutting protrusions 111 and a first elastic element 12. The rotating part 11 is provided with the protrusions 111, and the base 3 is provided with the first elastic element 12. The first elastic element 12 is disposed on the rotation path of the rotating part 11. When the rotating part 11 rotates to the point where the micro switch 5 activates the electronic door unlocking mechanism, the first elastic element 12 abuts against the protrusions 111 and generates a sudden resistance.

[0056] Furthermore, as a preferred embodiment, the contact box 41 is provided with a stationary contact, and the contact piece 42 includes an integrally formed connecting end and a deformable end. The connecting end is connected to the contact box 41, and the deformable end is provided with a moving contact. When the rotating part 11 applies pressure to the deformable end, the moving contact abuts against the stationary contact to keep the door closed.

[0057] Furthermore, as a preferred embodiment, the rotating part 11 is provided with a handle part 13 on the side away from the micro switch 5, and the base 3 is provided with a movable groove 14. The handle part 13 is disposed in the movable groove 14, and the handle part 13 and the rotating part 11 form a handle 1.

[0058] Furthermore, as a preferred embodiment, the base 3 is provided with a through groove 31, the rotating part 11 is rotatably disposed in the through groove 31, the rotating part 11 is provided with a pin 15, the two ends of the pin 15 are respectively connected to the upper and lower end walls of the through groove 31, and a second elastic member 16 is sleeved on the pin 15, the two ends of the second elastic member 16 are respectively connected to the base 3 and the rotating part 11.

[0059] Furthermore, as a preferred embodiment, the rotating part 11 is provided with a first tooth 17, and a damper 6 is provided on one side of the base 3. The teeth on the damper 6 mesh with the first tooth 17 for transmission. A buffer pin 7 is provided on the side wall of the through groove 31 away from the handle part 13. A hand-clip area 18 communicating with the bottom of the movable groove 14 is provided on the base 3.

[0060] Specifically, in this embodiment, the first direction is the direction towards the user.

[0061] Specifically, in this embodiment, the base 3 includes a handle mounting portion and a rotating mounting portion. The rotating mounting portion is integrally formed on one side of the handle mounting portion. A handle 1 is mounted on one side of the base 3. The handle 1 consists of a handle portion 13 and a rotating portion 11. A movable groove 14 is provided on the handle mounting portion, and the handle portion 13 is installed within it. The lower end of the movable groove 14 is provided with a handle 1 area. A through groove 31 is opened on the rotating mounting portion, and the rotating portion 11 is installed within the through groove 31. The rotating portion 11 is rotatably connected to the rotating mounting portion via a pin 15. The handle 1 is pulled in a first direction. The rotating part 11 can be driven to rotate counterclockwise. The upper and lower ends of the rotating part 11 are provided with through holes, and the middle position of the rotating part 11 is provided with a mounting hole communicating with the through holes. The shaft pin is installed in the mounting hole and passes through the through hole to connect with the upper and lower end walls of the through groove 31 of the base 3. A second elastic element 16 is sleeved on the pin 15. The second elastic element 16 is a torsion spring. One end of the second elastic element 16 is fixed to the base 3, and the other end of the second elastic element 16 is connected to the rotating part 11. When the rotating part 11 rotates, it compresses the second elastic element 16. When the tension is released, the second elastic element 16 drives the rotating part 11 to rotate and reset.

[0062] Specifically, in this embodiment, a contact box 41 is provided on the side of the base 3 away from the handle 13. The contact box 41 and the contact piece 42 are combined to form a contact assembly 4. An installation area 32 is provided on the base 3, and the contact box 41 is installed in the installation area 32. The contact piece 42 is connected to the side of the contact box 41 near the rotating part 11. A micro switch 5 is connected to the contact box 41. The micro switch 5 is connected to the electronic unlocking mechanism of the car door. The micro switch 5 is used to open the car door or keep the car door closed. The contact piece 42 includes an integrally formed connecting end and a deformable end. One end of the connecting end is connected to the contact box 41, and the other end of the connecting end is connected to the deformable end. A moving contact is provided on the deformable end. A stationary contact is provided on the side of the contact box 41 near the rotating part 11. The deformable end is elastic and can withstand the pressure of the rotating part 11. Under the action of the rotating part 11, the moving contact of the contact piece 42 deforms and abuts against the stationary contact on the contact box 41, connecting the contact box 41. When the rotating part 11 no longer applies pressure, the deformation is restored, releasing the contact between the moving contact of the contact piece 42 and the stationary contact of the contact box 41, thus disconnecting the contact box 41. When the car door is in the closed state, the moving contact of the contact piece 42 abuts against the stationary contact of the contact box 41 under the pressure of the rotating part 11. The contact box 41 transmits a signal to the micro switch 5, and the car door remains closed under the action of the car door electronic unlocking mechanism. When the rotating part 11 is initially rotated in the first direction, the rotating part 11 removes the pressure on the contact piece 42. Under the action of the restoring force of the elastic deformation of the deformed end, the contact between the contact piece 42 and the contact box 41 is released, causing the micro switch 5 to activate the car door electronic unlocking mechanism to open the car door.

[0063] Specifically, in this embodiment, a resistance feedback area is provided on the base 3 to inform the user that the door has been opened when the electronic unlocking mechanism of the car door is unlocked; the resistance feedback area includes a first elastic element 12 and a protrusion 111; the first elastic element 12 is provided on the side of the rotating part 11 away from the contact box 41 on the base 3. The first elastic element 12 is a butterfly torsion spring, and both ends of the first elastic element 12 are hinge ends 121. The hinge ends 121 are hinged to the back of the base 3, and an abutment end 122 is provided at the middle position of the connection between the two hinge ends 121. The abutment end 122 extends... At position 31, a protrusion 111 is provided on the rotating part 11. The protrusion 111 can abut against the contact end 122 of the first elastic member 12. When the protrusion 111 abuts against the first elastic member 12, the micro switch 5 opens the door. When the handle part 13 is pulled further, the protrusion 111 compresses the first elastic member 12. A damper 6 is provided on one side of the base 3. The damper 6 is provided with a second tooth. The rotating part 11 is provided with a first tooth 17. The first tooth 17 meshes with the second tooth for transmission. The damper 6 can reduce the rotation speed of the rotating part 11.

[0064] Specifically, in this embodiment, a mechanical unlocking mechanism 2 is connected to the rotating part 11. The mechanical unlocking mechanism 2 includes a zipper, which is connected to the car door. The zipper can open the car door. After the rotating part 11 rotates to a certain angle, the rotating part 11 drives the zipper to move towards the side closer to the handle part 13, thereby opening the car door. A buffer pin 7 is provided on one side of the through groove 31. The buffer pin 7 can reduce the impact force between the rotating part 11 and the base 3 when the second elastic member 16 resets the rotating part 11.

[0065] Specifically, in this embodiment, when the car door needs to be opened, the handle 13 is pulled, causing the rotating part 11 to rotate. After rotation, the fixed contact of the contact piece 42 no longer abuts against the stationary contact on the contact box 41. The moving contact moves 3.6mm, and the switch takes effect to control the door lock to open. At this time, the protrusion 111 of the rotating part 11 touches the first elastic element 12, generating a sudden force to let the customer know that it has been unlocked. When the micro switch 5 fails, the handle 13 is opened with continued force, and the rotating part 11 continues to rotate, driving the zipper to move. When the zipper moves 12mm, the door lock is unlocked.

[0066] Specifically, in this embodiment, when the handle 1 is released, the second elastic element 16 springs the handle 1 back, the damper 6 slows down the rebound speed of the handle, and finally presses it onto the buffer pin 7 to reduce the rebound impact sound. The first elastic element 12 then retracts onto the base 3 to return to its initial state. The handle 1 simultaneously possesses both electronic door unlocking mechanism and mechanical unlocking function, greatly improving safety performance and significantly saving costs by combining the two unlocking methods.

[0067] Specifically, in this embodiment, by setting a rotating part 11, the rotating part 11 is initially rotated to release the pressure of the rotating part 11 on the contact piece 42, so that the contact piece 42 and the contact box 41 are canceled, thereby controlling the micro switch 5 to open the car door. When the micro switch 5 fails, the rotating part 11 is rotated again, so that the rotating part 11 drives the mechanical unlocking mechanism 2 to open the car door. This can double guarantee the opening of the car door, making driving safer, and the structure is simple and the manufacturing cost is low.

[0068] Specifically, in this embodiment, by setting a resistance feedback area, the user can be notified that the electronically controlled microswitch 5 of the door lock has been turned on. By setting a protrusion 111 and a first elastic member 12, the protrusion 111 and the first elastic member 12 will come into contact and there will be a noticeable pause during the rotation of the rotating part 11, which can indicate to the user that the electronically controlled microswitch 5 of the door lock has been turned on.

[0069] Specifically, in this embodiment, whether the rotating part 11 applies pressure to the contact piece 42, and whether the moving contact of the contact piece 42 abuts against the stationary contact of the contact box 41, a signal is transmitted to the contact box 41, which controls the micro switch 5 to open or close. The handle part 13 makes it easier to rotate the rotating part 11. The second elastic element 16 allows the rotating part 11 to reset and close the door after the force on the handle part 13 is released following rotation of the rotating part 11. The damper 6 reduces the rotational speed of the rotating part 11, better protecting the handle 1. The buffer pin 7 reduces the collision between the rotating part 11 and the base 3, extending their service life. The handle area 18 makes it easier for the user to reach into the base 3 and pull the handle 13 to open the door. The resistance feedback area indicates to the user that the electronically controlled micro switch 5 of the door lock is open.
