Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an anti-mistouch self-locking inner handle with enhanced blocking feeling. Background Art

[0002] The existing Chinese patent with publication number CN 210598543U discloses an interior opening handle structure for an automobile, including a handle, a mounting base for fixing inside the vehicle door, and a cable assembly for opening the vehicle door. The handle includes a grip and a swing arm, the connecting end of the handle is fixed to the swing arm, the swing arm is hinged to 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 hinged connection between the swing arm and the mounting base, and the free end of the handle faces the rear of the vehicle.

[0003] However, the above-mentioned inner opening handle has the following disadvantages: the inner opening handle only has a mechanical unlocking function, requiring the driver and passengers to expend a lot of effort to pull the handle, which is not smart enough. In addition, the handle of the inner opening handle lacks a limiting structure for the handle during the opening process, making 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, shortening the service life of the inner opening handle, and it is in urgent need of improvement. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-accidental-touch self-locking inner handle with increased blocking feeling and an assembly method thereof, which has the effect of enabling the electronic lock to be opened by pulling the handle at a small angle, providing a better opening feel and extending the service life.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a self-locking inner handle with an increased sense of resistance to accidental touch, comprising a mounting base and a handle, the mounting base having a mounting slot, the handle being rotatably connected to the mounting slot, the mounting base having a micro switch electrically connected to an electronic lock, the handle having a pressing portion corresponding to the micro switch, the pressing portion being press-fitted with a spring of the micro switch;

[0006] The mounting base is provided with an elastic limiting structure, and when the handle is rotated relative to the mounting base and the micro switch is in the on state, the elastic limiting structure and the handle are elastically stopped;

[0007] The mounting base is provided with an inertia lock module corresponding to the handle, and the handle is provided with a linkage portion corresponding to the inertia lock module. When the vehicle body collides, the inertia lock module cooperates with the linkage portion stopper under the action of inertia to keep the pressing portion and the micro switch away from each other;

[0008] A buffer structure is provided between the handle and the mounting base, and the handle is in buffering cooperation with the mounting base through the buffer structure.

[0009] When the handle is in the correct position, the driver can pull the handle to unlock the door, and the driver can also pull the handle to unlock the door, so that the driver can unlock the door by pulling the handle at a small angle. The elastic limiting structure can play a buffering role when the handle is in the correct position, and can effectively prevent the handle from being damaged by the hard collision with the mounting base while improving the hand feeling. A buffer structure is provided between the handle and the mounting base. When the handle is reset after opening the inner handle, the buffer structure can buffer the impact force between the handle and the mounting base, thereby achieving a noise reduction effect. The elastic limiting structure cooperates with the buffer structure to extend the service life of the present invention. In addition, an inertia lock module is provided on the linkage part corresponding to the handle on the mounting base of the present invention. The inertia lock module includes a second reset torsion spring and an inertia lock hook rotatably connected to the mounting base. When the vehicle body collides, the inertia lock hook relies on its own inertia force to rotate relative to the mounting base and lock with the handle to prevent the door from opening accidentally. In 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 inertia 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. It has the effect of realizing the electronic lock by pulling the handle at a small angle, having a better opening feel, and extending the service life.

[0010] The present invention is further configured as follows: the handle is rotatably mounted on the mounting base via a plurality of rotating shafts; a first return torsion spring is provided between the handle and the mounting base; the first return torsion spring is sleeved on one of the rotating shafts; the first return torsion spring always has a tendency to drive the pressing portion and the micro switch to maintain a relatively distant movement.

[0011] By adopting the above technical solution and adding the first reset torsion spring, the purpose of the present invention that the handle can automatically reset by relying on the first reset torsion spring after the electronic lock is opened and the handle is released can be achieved.

[0012] The present invention 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 inertia lock hook cooperates with the linkage part stop, and the second reset torsion spring always has a tendency to drive the inertia lock hook away from the linkage part.

[0013] By adopting the above technical solution, when the vehicle body collides, the inertia 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 inertia 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.

[0014] The present invention is further configured as follows: the inertia 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 to stop.

[0015] By adopting the above technical solution, the stop block and the limit block are used to stop the inertia lock hook at all times, so that when a vehicle collision occurs, the inertia lock hook can promptly use the inertia force to rotate to the position for emergency locking with the handle, thereby ensuring the accuracy and timeliness of the emergency handling of the inertia lock structure.

[0016] The present invention is further configured as follows: the buffer structure includes a buffer block and a buffer stop portion, the buffer stop portion is fixed on the handle, the buffer block is fixed on the mounting base corresponding to the buffer stop portion, and the handle cooperates with the buffer block buffer stop through the buffer stop portion.

[0017] By adopting the above technical solution, when the handle is in the reset 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, prevent the handle or the mounting base from being damaged, and improve the service life of the present invention.

[0018] The present invention is further configured as follows: the elastic limiting structure includes a fixing part, a guide part integrally connected to the fixing part, and an elastic limiting part; the fixing part is fixedly connected to the mounting base through a fastener; the guide part cooperates with the linkage part for guidance; and the elastic limiting part cooperates with the elastic stop of the handle.

[0019] By adopting the above technical solution, the elastic limiting structure is detachably connected to the mounting base by fasteners, thereby improving the convenience of disassembly and assembly of the elastic limiting structure in the present invention. When the handle is rotated and the micro switch is pressed to turn on, the electronic lock is unlocked. At this time, the elastic limiting part and the elastic stop of the handle are integrated into the end of the fixed part, which improves the feel when the handle is rotated into place and the electronic lock is unlocked.

[0020] The present invention is further configured as follows: the elastic limiting portion includes a connecting section, a stop section and a reinforcement section; the stop section is fixedly connected to the fixing portion through the connecting section; the reinforcement section is bent and connected to one end of the stop section away from the connecting section; the bent connection between the reinforcement section and the stop section has a smooth arc transition, and a deformation space is left between the connecting section and the mounting base for the elastic limiting portion to undergo elastic deformation.

[0021] By adopting the above technical solution, in the initial state, the handle and the stop section of the elastic limit part do not contact each other. When the handle is pulled to turn on the micro switch, the handle and the stop section of the elastic limit part stop and cooperate. At this time, if the handle is continued to be pulled to rotate it again, the stop section is pushed upward, causing the connecting section to undergo elastic deformation and be pressed into the deformation space. At this time, the elastic limit part and the side wall of the handle close to the deformation space are subjected to 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. The reinforced section with a smooth arc transition can not only increase the stopping force of the stop section on the handle, but also when the handle passes the stop section and slides relative to the elastic limit part, the reinforced section with a smooth arc transition can effectively reduce the scratches and damage to the handle surface caused by sliding friction between the elastic limit part and the handle.

[0022] The present invention is further configured as follows: the elastic limiting structure includes a spring buckle integrally formed on the mounting base, the spring buckle includes an elastic sheet and a clamping protrusion fixed to the end of the elastic sheet, a reinforcing rib is fixedly connected between the elastic sheet and the mounting base, and the clamping protrusion cooperates with the elastic stop of the linkage part through the elastic sheet.

[0023] By adopting the above technical solution, the electronic lock is unlocked when the handle is rotated and the micro switch is pressed to turn on. At this time, the snap-on cam and the elastic stop of the handle improve the feel when the handle is rotated into place and the electronic lock is unlocked. If the handle is continued to be rotated, the handle pushes the cam and drives the elastic sheet to undergo elastic deformation until the cam and the side wall of the handle slide and rub against each other. During this process, the rotation resistance of the handle becomes greater and greater, and the resistance feel gradually becomes stronger. The addition of reinforcing ribs can improve the structural support strength of the elastic sheet and extend the service life of the invention.

[0024] The present invention is further configured as follows: the elastic limiting structure includes a mounting sleeve, an elastic member and a limiting plunger, the limiting plunger is movably arranged in the mounting sleeve, the elastic member always has a movement tendency to drive the limiting plunger to extend out of the mounting sleeve and stop with the linkage part, and the linkage part is provided with a guide inclined surface corresponding to the limiting plunger, the limiting plunger is guided and cooperated with the guide inclined surface, so that the limiting plunger is telescopically arranged in the mounting sleeve.

[0025] By adopting the above technical solution, in the initial state, the elastic part pushes the limit plunger to extend out of the mounting sleeve. When the handle is rotated and the micro switch is pressed to turn on, the electronic lock is unlocked. At this time, the handle and the limit plunger extending out of the mounting sleeve are elastically stopped, which improves the feel of the handle when it is rotated into the position and unlocks the electronic lock. If the handle is continued to be rotated, the handle pushes the limit plunger to gradually retract into the mounting sleeve under the guidance of the guide inclined surface and the limit plunger. In this process, the elastic part is compressed and the elastic force gradually increases, making the rotation resistance of the handle increasingly greater.

[0026] Another technical object of the present invention is to provide an assembly method for an anti-inadvertent-touch self-locking inner handle with an increased sense of resistance, comprising the following steps:

[0027] S1: Handle assembly: align the handle with the mounting slot and install it on the mounting base;

[0028] S2: Assembling the elastic limiting structure: rotating and adjusting the handle to a predetermined position so that the linkage portion of the handle and the elastic limiting structure are in a mutually avoiding position, and then fixing the elastic limiting structure to the mounting base;

[0029] S3: Micro switch assembly: Turn and adjust the position of the handle so that the pressing part of the handle and the micro switch are in a mutually avoiding position, and then fix the micro switch to the mounting base;

[0030] S4: Inertia lock assembly: Turn and adjust the position of the handle so that the linkage part of the handle and the inertia lock are in a position to avoid each other, and then fix the inertia lock to the mounting base to complete the overall assembly.

[0031] In summary, the present invention has the following beneficial effects:

[0032] 1. An elastic limiting structure is provided 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 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 resistance 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 to the position to turn on the micro switch, thereby improving the feel of the driver and passenger when the inner handle is opened into place, and facilitating the driver and passenger to understand the rotation position of the handle on the mounting base. It 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.

[0033] 2. An inertia lock module is set on the linkage part corresponding to the handle on the mounting base. The inertia lock module includes a second reset torsion spring and an inertia lock hook rotatably connected to the mounting base. When the vehicle body collides, the inertia lock hook relies on its own inertia force to rotate relative to the mounting base and lock 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 inertia 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 during a vehicle collision.

[0050] The present invention will be further described below with reference to the accompanying drawings. Specific embodiment 1

[0052] A self-locking inner handle that increases the sense of resistance and prevents accidental touch, such as Figure 1-2 and Figure 4-9As shown, it includes a mounting base 1 and a handle 2, the mounting base 1 is provided with a mounting slot 1b, the handle 2 is rotatably connected to the mounting slot 1b, the mounting base 1 is provided with a micro switch 3 electrically connected to the electronic lock, the handle 2 is provided with a pressing portion 22 corresponding to the micro switch 3, and the pressing portion 22 is pressed and matched with the spring of the micro switch 3; the mounting base 1 is provided with an elastic limiting structure 4, when the handle 2 is rotated relative to the mounting base 1 and the micro switch 3 is in the on state, the elastic limiting structure 4 and the handle 2 elastically stop; the mounting base 1 is provided with an inertia lock module corresponding to the handle 2, and the handle 2 is provided with a linkage portion 23 corresponding to the inertia lock module. When the vehicle body collides, the inertia lock module is matched with the linkage portion 23 under the action of inertia to keep the pressing portion 22 and the micro switch 3 away from each other; a buffer structure is provided between the handle 2 and the mounting base 1, and the handle 2 is buffered with the mounting base 1 through the buffer structure; the handle 2 is rotatably mounted on the mounting base 1 through a plurality of rotating shafts 20, and a first The reset torsion spring 201 and the first reset torsion spring 201 are sleeved on a rotating shaft 20. The first reset torsion spring 201 always has a tendency to drive the pressing part 22 and the micro switch 3 to keep a relatively distant movement. The addition of the first reset torsion spring 201 can achieve the purpose of the present invention that 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 automatic reset. In the event of an accidental power outage on the electronic lock, the handle 2 can cooperate with the mechanical transmission part of the electronic lock to perform emergency mechanical unlocking. When the handle 2 is rotated to the maximum opening relative to the mounting base 1, the linkage part 23 of the handle 2 can act on the mechanical transmission part to perform emergency mechanical unlocking on the electronic lock, so that the electronic lock can also be mechanically unlocked from the inside of the vehicle body in the power-off state, thereby improving the safety of the vehicle in unexpected situations. A limiting structure is also provided between the handle 2 and the mounting base 1. Under the limiting action of the limiting structure, the limiting structure can effectively prevent the handle 2 from rotating too much, resulting in cooperation failure.

[0053] like Figure 2 and Figure 10 As shown, the inertia lock module includes a second reset torsion spring 50 and an inertia lock hook 5 rotatably connected to the mounting base 1. The inertia lock hook 5 cooperates with the stopper of the linkage part 23, and the second reset torsion spring 50 always has a tendency to drive the inertia lock hook 5 away from the linkage part 23. When the vehicle body collides, the inertia 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.

[0054] like Figure 2-9As shown, 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 limit and stop. The limit and stop effect of the stop block 51 and the limit block 12 enables the inertia lock hook 5 to always remain in the predetermined position, ensuring that when the vehicle body collides, the inertia lock hook 5 can promptly utilize the inertia force to rotate to the position of emergency locking with the handle 2, ensuring the emergency handling accuracy and timeliness of the inertia lock structure; the buffer structure includes a buffer block 11 and a buffer stop portion 24, the buffer stop portion 24 is fixed on the handle 2, and the buffer block 11 is fixed on the mounting base 1 corresponding to the buffer stop portion 24. The handle 2 cooperates with the buffer block 11 buffer stop through the buffer stop portion 24. When the electronic lock is opened and the handle 2 is in the reset process, 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, preventing damage to the handle 2 or the mounting base 1, and improving the service life of the present invention.

[0055] like Figure 3 and Figure 9As shown, the elastic limiting structure 4 includes a fixing portion 41, a guide portion 43 integrally connected to the fixing portion 41, and an elastic limiting portion 42. The fixing portion 41 is fixedly connected to the mounting base 1 by a fastener 411. The guide portion 43 is guided and matched with the linkage portion 23. The elastic limiting portion 42 is matched with the elastic stop of the handle 2, so that the elastic limiting structure 4 is detachably connected to the mounting base 1 by the fastener 411, which improves the convenience of disassembly and assembly of the elastic limiting structure 4 in the present invention. When the handle 2 is rotated and the micro switch 3 is pressed to turn on, the electronic lock is unlocked. At this time, the elastic limiting portion 42 integrally provided at the end of the fixing portion 41 elastically stops the handle 2, improving the feel when the handle 2 is rotated into place and unlocking the electronic lock position; the elastic limiting portion 42 includes a connecting section 421, a stopping section 422 and a reinforcing section 423, the stopping section 422 is fixedly connected to the fixing portion 41 through the connecting section 421, the reinforcing section 423 is bent and connected to the end of the stopping section 422 away from the connecting section 421, the bending connection between the reinforcing section 423 and the stopping section 422 has a smooth arc transition, and the connecting section 421 and the installation A deformation space 1a is reserved between the base 1 for the elastic limiting portion 42 to undergo elastic deformation. In the initial state, the handle 2 and the stop section 422 of the elastic limiting portion 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 portion 42 are engaged. At this time, if the handle 2 is continued to be pulled to rotate again, the stop section 422 is pushed upward so that the connecting section 421 undergoes elastic deformation and is pressed into the deformation space 1a. At this time, the elastic limiting portion 42 and the handle 2 are close to the deformation space 1a. Sliding friction occurs on the side wall on one side, and the resistance feeling of the handle 2 in the rotation gradually increases during this process until the handle 2 stops rotating when it rotates to the maximum opening position relative to the base. The reinforcement section 423 with a smooth arc transition can not only increase the stopping force of the stop section 422 on the handle 2, but also, when the handle 2 passes the stop section 422 and slides relative to the elastic limiting part 42, the reinforcement section 423 with a smooth arc transition can effectively reduce the scratches and damage to the surface of the handle 2 caused by the sliding friction between the elastic limiting part 42 and the handle 2.

[0056] When the handle 2 is in the correct position, the handle 2 is rotated to the position where the micro switch 3 is turned, and the micro switch 3 is pressed to open, thereby unlocking the electronic lock. A buffer structure is provided between the handle 2 and the mounting base 1. When the handle 2 is reset after opening the inner handle, the buffer structure can buffer the impact force between the handle 2 and the mounting base 1, thereby achieving a noise reduction effect. The elastic limiting structure 4 cooperates with the buffer structure to extend the service life of the present invention. In addition, the present invention provides an inertia lock module on the mounting base 1 corresponding to the linkage part 23 of the handle 2. The inertia lock module includes a second reset torsion spring 50 and an inertia lock hook 5 rotatably connected to the mounting base 1. When the vehicle body collides, the inertia 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. In this process, the second reset torsion spring 50 accumulates elastic potential energy. When the vehicle body collision ends, 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, which can effectively prevent the door from opening accidentally during a collision. It has the effect of being able to open the electronic lock by pulling the handle 2 at a small angle, having a better opening feel, and extending the service life. Specific embodiment 2

[0058] A self-locking inner handle that increases the sense of resistance and prevents accidental touch, such as Figure 11-13As shown, the difference between this embodiment and the specific embodiment 1 is that: the elastic limiting structure 4 includes a spring buckle 6 integrally formed on the mounting base 1, the spring buckle 6 includes an elastic sheet 61 and a locking protrusion 62 fixedly arranged at the end of the elastic sheet 61, and a reinforcing rib 63 is fixedly connected between the elastic sheet 61 and the mounting base 1, and the locking protrusion 62 cooperates with the elastic stop of the linkage part 23 through the elastic sheet 61. When the handle 2 is rotated and the micro switch 3 is pressed to turn on, the electronic lock is unlocked. At this time, the locking protrusion 62 of the spring buckle 6 elastically stops with the handle 2, improving the feel of the handle 2 when it is rotated into place and unlocks the electronic lock position. If the handle 2 is continued to be rotated subsequently, the handle 2 pushes the locking protrusion 62 and drives the elastic sheet 61 to undergo elastic deformation until the locking protrusion 62 and the side wall of the handle 2 slide and rub. In this process, the rotation resistance of the handle 2 becomes greater and greater, and the blocking feel gradually becomes stronger. The addition of the reinforcing rib 63 can improve the structural support strength of the elastic sheet 61 and extend the service life of the invention.

[0059] The other structures of this embodiment are the same as those of the first embodiment and will not be described again here. Specific embodiment three

[0061] A self-locking inner handle that increases the sense of resistance and prevents accidental touch, such as Figure 14-15 As shown, the difference between this embodiment and the specific embodiment 1 is that the elastic limiting structure 4 includes a mounting sleeve 7, an elastic member 71 and a limiting plunger 72, the limiting plunger 72 is movably arranged in the mounting sleeve 7, the elastic member 71 always has a movement tendency to drive the limiting plunger 72 to extend out of the mounting sleeve 7 and stop with the linkage part 23, and the linkage part 23 is provided with a guide inclined surface 23a corresponding to the limiting plunger 72, the limiting plunger 72 and the guide inclined surface 23a are guided and matched, so that the limiting plunger 72 is telescopically arranged in the mounting sleeve 7, and the elastic member 71 pushes the limiting plunger 72 in the initial state. The limit plunger 72 extends out of the mounting sleeve 7. When the handle 2 is rotated and the micro switch 3 is pressed to turn on, the electronic lock is unlocked. At this time, the handle 2 and the limit plunger 72 extending out of the mounting sleeve 7 are elastically stopped, which improves the feel of the handle 2 when it is rotated into the position and unlocks the electronic lock. If the handle 2 is continued to be rotated, the handle 2 pushes the limit plunger to gradually retract into the mounting sleeve 7 under the guidance of the guide inclined surface 23a and the limit plunger 72. In this process, the elastic member 71 is compressed and the elastic force gradually increases, making the rotation resistance of the handle 2 increasingly greater.

[0062] The other structures of this embodiment are the same as those of the first embodiment and will not be described again here.

[0063] Another technical object of the present invention is to provide an assembly method for an anti-inadvertent-touch self-locking inner handle with an increased sense of resistance, comprising the following steps:
