Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an inner handle with a spring structure for increasing a sense of resistance. Background Art

[0002] The existing Chinese patent with announcement number CN 210598543U discloses an internal opening handle structure of an automobile, including a handle, a mounting base for fixing in a door, and a cable assembly for opening the door, the handle including a handle and a swing arm, the connecting end of the handle is fixed to the swing arm, the swing arm is hinged on the mounting base, the cable assembly is connected to the swing arm, the connection between the swing arm and the cable assembly, and the handle are located on the same side of the hinge between the swing arm and the mounting base, and the free end of the handle faces the rear of the automobile.

[0003] However, the above-mentioned inner opening handle has the following disadvantages: the inner opening handle only has a mechanical unlocking function, which requires the driver and passengers to expend great effort to pull the handle, and is not smart enough. In addition, the handle of the inner opening handle lacks a limiting structure for the handle during the opening process, which makes it impossible for the passenger to make a correct judgment on the opening force and angle of the handle. When the passenger pulls the handle too hard, it may cause irreversible deformation of the handle and the swing arm, which will aggravate the wear of the handle and the swing arm after long-term use and shorten the service life of the inner opening handle, which needs to be improved urgently. Utility Model Content

[0004] The utility model aims to provide an inner handle with a spring structure that increases the sense of resistance, which can realize opening the electronic lock by pulling the handle at a small angle, has a better opening feel and prolongs the service life.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions: an inner handle of a spring structure with increased resistance feeling, comprising a mounting base and a handle rotatably connected to the mounting base, the mounting base being provided with a micro switch electrically connected to an electronic lock, the handle rotating relative to the mounting base and controlling the micro switch to open and close;

[0006] The mounting base is provided with an elastic limiting structure, which includes an elastic limiting portion that can undergo elastic deformation. When the handle is rotated relative to the mounting base and the micro switch is in an on state, the elastic limiting portion and the handle are elastically stopped.

[0007] By adopting the above technical solution, when the driver and passenger pulls the handle from inside the vehicle body to unlock the inner handle, the driver and passenger only needs to pull the handle at a small angle to rotate it relative to the mounting base. When the handle is rotated to the right position, the micro switch is pressed to turn it on, thereby unlocking the electronic lock. When the micro switch is turned on, the handle just contacts the elastic limiting part of the elastic limiting structure. At this time, if the handle is continued to be pulled to continue rotating, the elastic stopping force of the elastic limiting part is used to act on the handle, so that the handle is subjected to a large blocking force at the moment of rotation after the micro switch is turned on, so as to remind the driver and passenger that the handle has been rotated. The utility model can also be used to open the electronic lock by pulling the handle at a small angle, thereby improving the feel of the electronic lock and providing a better opening feel and extending the service life of the electronic lock.

[0008] The utility model is further configured as follows: the elastic limiting structure comprises a fixing portion integrally connected to the elastic limiting portion, and the fixing portion is fixedly connected to the mounting base via a fastener.

[0009] By adopting the above technical solution, the elastic limiting structure can be detachably connected to the mounting base through the fasteners, thereby improving the convenience of disassembly and assembly of the elastic limiting structure in the utility model.

[0010] The utility model is further configured as follows: the elastic limiting portion includes a connecting section and a stop section, the stop section is fixedly connected to the fixing portion via the connecting section, and a deformation space is reserved between the connecting section and the mounting base for elastic deformation of the elastic limiting portion.

[0011] By adopting the above technical solution, the handle and the stop section of the elastic limiting part do not contact each other in the initial state. When the handle is pulled to turn on the micro switch, the handle and the stop section of the elastic limiting part stop and cooperate. At this time, if the handle continues to be pulled to rotate again, the stop section is pushed upward to cause the connecting section to undergo elastic deformation and be pressed into the deformation space. At this time, the elastic limiting part and the side wall of the handle close to the deformation space undergo sliding friction. During this process, the resistance of the handle rotation gradually increases until the handle stops rotating when it rotates to the maximum opening position relative to the base.

[0012] The utility model is further configured as follows: the elastic limiting structure is provided with a guide portion in an inclined manner corresponding to the handle, and the handle is guided and slidably moved to the connecting section by the guide portion.

[0013] By adopting the above technical solution, the addition of the guide portion enables the handle to be more smoothly guided to slide into the connecting section and cooperate with the elastic limiting portion.

[0014] The utility model is further configured as follows: the handle comprises a grip portion and a pressing portion, and the pressing portion is pressed and matched with the micro switch.

[0015] By adopting the above technical solution, the driver and passengers can pull the buckle to drive the handle to rotate, and then drive the pressing part on the handle to press or release the micro switch to open and close the electronic lock.

[0016] The utility model is further configured as follows: the handle is provided with a buffer stop portion, the mounting base is fixedly provided with a buffer block corresponding to the buffer stop portion, and the handle cooperates with the buffer block buffer stop via the buffer stop portion.

[0017] By adopting the above technical solution, when the handle is in the resetting process after the electronic lock is opened, the buffer block and the buffer stop part can greatly buffer and reduce the impact force between the handle and the mounting base, thereby preventing damage to the handle or the mounting base. At the same time, it can also greatly reduce noise and improve the service life of the utility model.

[0018] The utility model is further configured as follows: the handle is rotatably mounted on the mounting base via a rotating shaft, a first reset torsion spring is provided between the handle and the mounting base, the first reset torsion spring is sleeved on the rotating shaft, and the first reset torsion spring always has a tendency to drive the handle to rotate in a direction away from the micro switch.

[0019] By adopting the above technical solution and adding the first reset torsion spring, the utility model can realize the purpose that after the electronic lock is opened and the handle is released, the handle can be automatically reset by relying on the first reset torsion spring.

[0020] The utility model is further configured as follows: the mounting base is provided with an inertia lock module corresponding to the handle, and when a vehicle body collides, the inertia lock module cooperates with the handle stopper under the action of inertia to keep the handle away from the micro switch.

[0021] By adopting the above technical solution and adding the inertial lock module, when the vehicle body collides, the inertial lock module uses its own inertial force to prioritize the action of the handle, so that the inertial lock locks the handle to prevent the handle from rotating relative to the mounting base when the vehicle body collides, causing the door to open accidentally, thereby improving the safety of the vehicle.

[0022] The utility model is further configured as follows: the inertia lock module includes a second reset torsion spring and an inertia lock hook rotatably connected to the mounting base; the handle is provided with a linkage portion corresponding to the inertia lock hook; the inertia lock hook cooperates with the handle stopper; and the second reset torsion spring always has a tendency to drive the inertia lock hook to move away from the handle.

[0023] By adopting the above technical solution, when the vehicle body collides, the inertial lock hook relies on its own inertia force to rotate relative to the mounting base and locks with the handle to prevent the door from opening accidentally. During this process, the second reset torsion spring accumulates elastic potential energy. When the vehicle body collision is over, the second reset torsion spring releases the elastic potential energy and drives the inertial lock hook away from the handle to achieve automatic reset. At this time, the driver and passengers can open the door from the inside to escape.

[0024] The utility model is further configured as follows: the inertial locking hook is provided with a stop block, the mounting base is provided with a limit block corresponding to the stop block, and the stop block cooperates with the limit block limit stop.

[0025] By adopting the above technical solution and utilizing the limiting stop function of the stop block and the limit block, the inertia lock hook can always be kept in a predetermined position, ensuring that when a vehicle body collides, the inertia lock hook can promptly utilize the inertia force to rotate to a position for emergency locking with the handle, thereby ensuring the accuracy and timeliness of emergency handling of the inertia lock structure.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. An elastic limiting structure is arranged on the mounting base corresponding to the handle, and the elastic limiting part of the elastic limiting structure is used to elastically stop the linkage part of the handle, so that the driver and the passenger can pull the handle at a small angle to rotate it relative to the mounting base. When the handle is rotated into place, the micro switch is pressed to open, thereby unlocking the electronic lock. When the micro switch is turned on, the handle just contacts the elastic limiting part of the elastic limiting structure. At this time, if the handle is continued to be pulled to continue rotating, the elastic stopping force of the elastic limiting part is used to act on the handle, so that the handle is subjected to a large blocking force at the moment of rotation after the micro switch is turned on, which is used to remind the driver and the passenger that the handle has been rotated to the position to turn on the micro switch, thereby improving the feel of the driver and the passenger when the inner handle is opened into place, and facilitating the driver and the passenger to understand the rotation position of the handle on the mounting base, which has the effect of realizing the electronic lock being opened by pulling the handle at a small angle, having a better opening feel, and extending the service life.

[0028] 2. An inertial lock module is set on the linkage part corresponding to the handle on the mounting base. The inertial lock module includes a second reset torsion spring and an inertial lock hook rotatably connected to the mounting base. When the vehicle body collides, the inertial lock hook relies on its own inertia force to rotate relative to the mounting base and locks with the handle to prevent the door from opening accidentally. During this process, the second reset torsion spring accumulates elastic potential energy. When the vehicle body collision ends, the second reset torsion spring releases the elastic potential energy and drives the inertial lock hook away from the handle to achieve automatic reset. At this time, the driver and passengers can open the door from the inside to escape, which can effectively prevent the door from opening accidentally when the vehicle body collides.

DETAILED DESCRIPTION

[0040] The utility model is further described below in conjunction with the accompanying drawings.

[0041] An inner handle with a spring structure that increases the sense of resistance, such as Figure 1-2 and Figure 4-9As shown, it includes a mounting base 1 and a handle 2 rotatably connected to the mounting base 1, the mounting base 1 is provided with a micro switch 3 electrically connected to the electronic lock, the handle 2 is rotatably mounted on the mounting base 1 through a rotating shaft 20, a first reset torsion spring 201 is provided between the handle 2 and the mounting base 1, the first reset torsion spring 201 is sleeved on a rotating shaft 20, the first reset torsion spring 201 always has a movement tendency to drive the handle 2 to rotate in a direction away from the micro switch 3, the addition of the first reset torsion spring 201 can realize the utility model in After the electronic lock is opened and the handle 2 is released, the handle 2 can rely on the first reset torsion spring 201 to achieve the purpose of automatic reset; the handle 2 includes a buckle portion 21 and a pressing portion 22, and the pressing portion 22 is pressed and matched with the micro switch 3. The driver and the passenger can drive the handle 2 to rotate by pulling the buckle portion 21, and then drive the pressing portion 22 on the handle 2 to press or release the micro switch 3 to open and close the electronic lock. In addition, the handle 2 is provided with a buffer stop portion 24, and the mounting base 1 is fixed with a buffer block 11 corresponding to the buffer stop portion 24. The handle 2 is The buffer stop portion 24 cooperates with the buffer block 11 buffer stop. When the handle 2 is in the resetting process after the electronic lock is opened, the buffer block 11 and the buffer stop portion 24 can greatly buffer and reduce the impact force between the handle 2 and the mounting base 1, prevent the handle 2 or the mounting base 1 from being damaged, and at the same time greatly reduce noise, thereby improving the service life of the utility model; the mounting base 1 includes an elastic limiting structure 4 and a fixing portion 41 integrally connected to the elastic limiting portion 42. The elastic limiting portion 42 is provided with two, and the two elastic limiting portions 42 are symmetrically arranged on both sides of the fixing portion 41. The elastic limiting structure 4 includes an elastic limiting portion 42 that can undergo elastic deformation. When the handle 2 rotates relative to the mounting base 1 and the micro switch 3 is in the on state, the elastic limiting portion 42 elastically stops the handle 2, and the fixing portion 41 is fixedly connected to the mounting base 1 by a fastener 411, so that the elastic limiting structure 4 is detachably connected to the mounting base 1 by the fastener 411, thereby improving the convenience of disassembly and assembly of the elastic limiting structure 4 in the utility model.

[0042] like Figure 3-9As shown, the elastic limiting portion 42 includes a connecting section 421, a stop section 422 and a reinforcing section 423. The stop section 422 is fixedly connected to the fixing portion 41 through the connecting section 421, and a deformation space 1a is reserved between the connecting section 421 and the mounting base 1 for the elastic limiting portion 42 to undergo elastic deformation. The reinforcing section 423 is bent and connected to the end of the stop section 422 away from the connecting section 421. The bending connection between the reinforcing section 423 and the stop section 422 has a smooth arc transition. The reinforcing section 423 with a smooth arc transition can improve the stopping effect of the stop section 422 on the handle 2. At the same time, when the handle 2 passes over the stop section 422 and relatively slides sideways with the elastic limiting portion 42, the reinforcing section 423 with a smooth arc transition can effectively reduce the situation where the surface of the handle 2 is scratched and damaged due to sliding friction between the elastic limiting portion 42 and the handle 2. In the initial state, the handle 2 and the stop section 422 of the elastic limiting part 42 do not contact each other. When the handle 2 is pulled to turn on the micro switch 3, the handle 2 and the stop section 422 of the elastic limiting part 42 stop and cooperate. At this time, if the handle 2 is continued to be pulled to make it rotate again, the stop section 422 is pushed upward so that the connecting section 421 is elastically deformed and pressed into the deformation space 1a. At this time, the elastic limiting part 42 and the side wall of the handle 2 close to the deformation space 1a have sliding friction. During this process, the resistance of the handle 2 rotation gradually increases until the handle 2 stops rotating when it rotates to the maximum opening position relative to the base. In addition, the elastic limiting structure 4 is inclined with a guide part 43 corresponding to the handle 2. The handle 2 is guided to slide to the connecting section 421 by the guide part 43. The addition of the guide part 43 allows the handle 2 to be more smoothly guided to slide into the connecting section 421 and cooperate with the elastic limiting part 42.

[0043] like Figure 5-10As shown, the mounting base 1 is provided with an inertial lock module corresponding to the handle 2. When the vehicle body collides, the inertial lock module cooperates with the handle 2 stopper under the action of inertia, so that the handle 2 and the micro switch 3 are kept away from each other. The addition of the inertial lock module enables the inertial lock module to use its own inertial force to prioritize the action of the handle 2 when the vehicle body collides, so that the inertial lock locks the handle 2, preventing the handle 2 from rotating relative to the mounting base 1 when the vehicle body collides, causing the door to open accidentally, thereby improving the safety of vehicle use; the inertial lock module includes a second reset torsion spring 50 and an inertial lock hook 5 rotatably connected to the mounting base 1, and the handle 2 is provided with a linkage part 23 corresponding to the inertial lock hook 5. The inertial lock hook 5 cooperates with the handle 2 stopper, and the second reset torsion spring 50 always has a tendency to drive the inertial lock hook 5 away from the handle 2. When the vehicle body collides, the inertial lock hook 5 relies on its own inertia force to rotate relative to the mounting base 1 and lock with the handle 2 to prevent the door from opening accidentally. During this process, the second reset torsion spring 50 accumulates elastic potential energy. When the vehicle body collision is over, the second reset torsion spring 50 releases the elastic potential energy and drives the inertia lock hook 5 away from the handle 2 to achieve automatic reset. At this time, the driver and passengers can open the door from the inside to escape; the inertia lock hook 5 is provided with a stop block 51, and the mounting base 1 is provided with a limit block 12 corresponding to the stop block 51. The stop block 51 cooperates with the limit block 12 to stop. By using the limit stop effect of the stop block 51 and the limit block 12, the inertia lock hook 5 can always be kept in a predetermined position, ensuring that when the vehicle body collides, the inertia lock hook 5 can promptly use the inertia force to rotate to the position of emergency locking with the handle 2, thereby ensuring the accuracy and timeliness of emergency handling of the inertia lock structure.

[0044] The basic working principle of the utility model is as follows: when the driver and passenger pulls the handle 2 from inside the vehicle body to unlock the inner handle, the driver and passenger only needs to pull the handle 2 at a small angle to rotate it relative to the mounting base 1. When the handle 2 is rotated to the right position, the micro switch 3 is pressed to turn it on, thereby unlocking the electronic lock. When the micro switch 3 is turned on, the handle 2 just contacts the elastic limiting portion 42 of the elastic limiting structure 4. At this time, if the handle 2 is continued to be pulled to make it continue to rotate, the elastic stopping force of the elastic limiting portion 42 is used to act on the handle 2, so that the handle 2 is subjected to a large blocking force at the moment of rotation after the micro switch 3 is turned on, so as to remind the driver and passenger that the handle 2 is in a state of rotation. 2 has been rotated to the position of turning on the micro switch 3, which improves the feel of the driver and passenger when the inner handle is fully opened, and is convenient for the driver and passenger to understand the rotation position of the handle 2 on the mounting base 1, so that the driver and passenger can achieve the purpose of pulling the handle 2 at a small angle to open the inner handle. In addition, the elastic limiting portion 42 of the elastic limiting structure 4 can play a buffering role when the handle 2 is fully opened, and can effectively prevent the damage caused by the hard collision between the handle 2 and the mounting base 1 while improving the feel, thereby extending the service life of the utility model, and has the effect of realizing the electronic lock being opened by pulling the handle 2 at a small angle, having a better opening feel, and extending the service life.
