[0002] Hidden external opening handle, that is, the door external opening handle is flush with the door outer panel, and the handle is hidden in the internal cavity of the door, and the handle needs to be unfolded to perform operations. With the rapid development of automobile intelligence and electrification, the application of electric opening and closing hidden external opening handles can give users an electrified and intelligent experience, so electric opening and closing hidden external opening handles are favored by new energy vehicles. Almost all new models released now use hidden external opening handles. The expansion and retraction of the electric opening and closing hidden external opening handles are driven by the actuator to realize the expansion and retraction actions, and the control of the expansion and retraction of the electric opening and closing hidden external opening handles is particularly important.

[0003] The principle of the existing electric opening and closing hidden external opening handle is to trigger the micro switch in the base of the car handle by turning the handle. The micro switch is triggered and sends a signal to the door control system, and the door control system controls the door to unlock; as shown in the attached Figure 1 As shown, the existing micro switch includes a trigger sheet 6 inserted into the inside of the micro switch. By squeezing the trigger sheet 6, the trigger sheet 6 triggers the button 7 in the micro switch to generate an electrical signal. However, the trigger sheet 6 of the existing micro switch has a large fold angle and is arranged in a straight line, so it is easily deformed by external force, thereby causing the button 7 to be accidentally touched.

DETAILED DESCRIPTION

[0063] The following will describe the implementation of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0064] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0065] As attached Figure 1 As shown, the micro switch 1 in the prior art is generally fixed to the housing by a bent trigger piece 6, and the trigger piece 6 located at the top of the housing is straight, so that there is a large space between the trigger piece 6 and the top of the housing, which is easily squeezed by external force and deformed, so that the trigger piece 6 continues to trigger the button 7 of the micro switch 1.

[0066] This embodiment proposes a micro switch and a hidden car handle structure, as shown in the attached Figure 2As shown, the micro switch 1 includes: a switch body 11, a contact 12, a spring 13 and a limiting rib 15; the switch body 11 is a prior art, and various electronic devices are arranged inside it for receiving and sending signals; the top of the switch body 11 is provided with a contact 12; the switch body 11 is also provided with a spring 13, and the spring 13 includes a fixed portion 131, a first inclined portion 132 and a second inclined portion 133, one end of the fixed portion 131 is arranged in the switch body 11, and the other end is bent toward the contact 12 and extends to the outside of the switch body 11; one end of the first inclined portion 132 is connected to the fixed portion 131, and the other end is upturned relative to the fixed portion 131; one end of the second inclined portion 133 is connected to the first inclined portion 132, and the other end is pressed down relative to the first inclined portion 132 and extends to the top of the contact 12 to trigger and release the contact 12.

[0067] The fixing portion 131, the first inclined portion 132 and the second inclined portion 133 are an integral whole. The first inclined portion 132 is formed by bending the fixing portion 131, and the second inclined portion 133 is formed by bending one end of the first inclined portion 132 away from the fixing portion 131. The first inclined portion 132 and the second inclined portion 133 are formed by bending, which can effectively improve the strength and stability of the spring piece 13 itself and the anti-deformation performance to prevent the spring piece 13 from being deformed by external force, and after the contact 12 is triggered and the spring piece 13 is released, the rebound effect of the spring piece 13 can be effectively reduced; at the same time, through the arrangement of the first inclined portion 132 and the second inclined portion 133, the space between the spring piece 13 and the upper surface of the switch body 11 can also be reduced, thereby reducing the situation where the spring piece 13 is squeezed and bent by external force.

[0068] In this embodiment, a limiting rib 15 is further provided on the top of the switch body 11 and protrudes from the upper surface of the switch body 11. The limiting rib 15 corresponds to the bending part of the fixing portion 131. The limiting rib 15 is used to limit the bending angle of the fixing portion 131, thereby further preventing the spring sheet 13 from being bent too much by external force, causing plastic deformation and being unable to restore the initial bending angle.

[0069] Furthermore, chamfers 16 are provided on both sides of the top of the limiting rib 15 along the length direction of the spring piece 13. The chamfers 16 can facilitate the spring piece 13 to bend under external force so as to touch the contact 12; at the same time, the setting of the chamfers 16 can prevent the spring piece 13 from being damaged or indented when the right angles at both ends (right angles when the chamfers 16 are not set) contact the spring piece 13, thereby reducing the service life of the spring piece 13.

[0070] In this embodiment, a slot is provided at one end of the switch body 11 away from the contact 12, with the notch of the slot facing upward, and one end of the fixing portion 131 is inserted into the slot, that is, the spring piece 13 is detachably provided on the switch body 11 to facilitate replacement of the spring piece 13.

[0071] In this embodiment, a through hole 14 is provided inside the spring piece 13, and the through hole 14 extends from the second inclined portion 133 to the fixed portion 131, and the through hole 14 is a waist-shaped hole; the waist-shaped hole can improve the stability of the spring piece 13, reduce the vibration generated by the movement of the spring piece 13, and improve the durability of the spring piece 13, so that the spring piece 13 has a stronger ability to withstand external forces, which can effectively improve the service life of the spring piece 13.

[0072] This embodiment also provides a hidden car handle structure, as shown in the attached Figure 3 , Attachment Figure 4 and attached Figure 5 As shown, the hidden automobile handle structure includes the above-mentioned micro switch 1, which also includes a base 2, a hidden handle 3, a trigger plate 4 and an inertia lock 5; the base 2 is arranged in the cavity of the car door, and a plurality of micro switches 1 are arranged on the base 2 for monitoring the position of the hidden handle 3; a rotation groove 21 and a mounting groove 22 are arranged on the base 2, and the hidden handle 3 is rotatably arranged in the rotation groove 21 to facilitate the hidden handle 3 to rotate outward to open; a trigger plate 4 is rotatably arranged on one side of the base 2, and the trigger plate 4 cooperates with the hidden handle 3 and the micro switch 1, and is used to monitor the position of the hidden handle 3 through the micro switch 1; an inertia lock 5 is arranged on the mounting groove 22 of the base 2, and the inertia lock 5 cooperates with the trigger plate 4 to prevent the trigger plate 4 from triggering the micro switch 1 under the inertia force.

[0073] In this embodiment, a control system is disposed inside the base 2, and the control system is connected to the micro switch 1. The micro switch 1 matched with the trigger plate 4 is used to monitor the position of the hidden handle 3 and can send a signal to the control system.

[0074] By opening the hidden handle 3 and rotating it under manual pulling force, one end of the hidden handle 3 will squeeze the trigger plate 4, so that the trigger plate 4 rotates on one side of the base 2. After the trigger plate 4 rotates, it contacts the spring 13 of the micro switch 1 located on the base 2. As the hidden handle 3 continues to rotate, the trigger plate 4 rotates and squeezes the spring 13 until the hidden handle 3 is fully opened. At this time, the trigger plate 4 squeezes the spring 13 to make it abut against the contact 12, and the micro switch 1 generates an electrical signal and sends the electrical signal to the control system. The control system sends a signal to the unlocking component of the vehicle door (the unlocking component is a prior art) to unlock the vehicle door, so that the vehicle door can be pulled open;

[0075] When the hidden handle 3 is rotated under manual pulling, but the rotation angle is small, the trigger plate 4 cannot be squeezed to contact the spring piece 13. At this time, the door is in a locked state and cannot be opened by external force.

[0076] In this embodiment, the inertia lock 5 is used to prevent the hidden handle 3 from generating an inertia force to rotate during driving, causing the hidden handle 3 to squeeze the trigger plate 4, and the trigger plate 4 triggers the micro switch 1 to open the door.

[0077] Specifically, the inertia lock 5 is rotatably arranged on the mounting groove 22. When the car encounters a collision or the like, causing the hidden handle 3 to generate an inertial force to rotate outward, the inertia lock 5 will also rotate accordingly and cooperate with the trigger plate 4, so that the rotation of the trigger plate 4 is limited under the force of the hidden handle 3 to open outward, thereby preventing the micro switch 1 from being triggered and preventing the door from opening. At this time, the rotation angle of the hidden handle 3 will also be blocked by the trigger plate 4 and cannot be fully opened.

[0078] In this embodiment, as shown in the attached Figure 6 and attached Figure 7 As shown, the inertia lock 5 includes a pin 51, a stopper 52, a torsion spring 54 and a fixed protrusion 55. The pin 51 is arranged on the mounting groove 22 and fixed to the mounting groove 22 to prevent the pin 51 from being separated from the mounting groove 22. The stopper 52 is rotatably arranged on the pin 51 and can rotate in the mounting groove 22. A matching groove 53 is arranged on one side of the stopper 52. The matching groove 53 cooperates with the trigger plate 4 to prevent the trigger plate 4 from rotating. A fixed protrusion 55 and an abutment portion 56 are arranged on the top of the stopper 52. A torsion spring 54 is rotatably arranged on the pin 51, and one end of the torsion spring 54 supports the mounting groove 22. , and the other end supports the stopper 52, so that the stopper 52 has a force to rotate away from the base 2, but cannot rotate under the action of the abutment portion 56 set on the top of the stopper 52 and the mounting groove 22, so as to limit the fixed protrusion 55 in the mounting groove 22, and at the same time, the top of the torsion spring 54 is supported on the bottom of the stopper 52; the fixed protrusion 55 is supported on the inner top wall of the mounting groove 22 under the action of the torsion spring 54, and a protrusion limiting groove 23 is provided inside the mounting groove 22, and the protrusion limiting groove 23 is located on the side of the fixed protrusion 55 close to the base 2 and at the top of the fixed protrusion 55.

[0079] Specifically, when the car collides or rotates, the block 52 overcomes the force of the torsion spring 54 and rotates in the direction close to the base 2 under the inertial force of the collision or rotation. As the block 52 rotates, the fixed protrusion 55 on the top of the block 52 slides along the inner top wall of the installation groove 22 until it slides into the protrusion limiting groove 23, and under the vertical elastic force of the torsion spring 54 (in the initial state, the torsion spring 54 is in a compressed state), the block 52 slides upward along the pin shaft 51, and the fixed protrusion 55 on the top of the block 52 slides into the protrusion limiting groove 23. At this time, the block 52 is in a locked state, and the block 52 cannot return to its original position under the action of the torsion spring 54, and will not rotate under the external inertial force; at the same time, the matching groove 53 cooperates with the trigger plate 4 to limit the rotation of the trigger plate 4 and prevent the trigger plate 4 from accidentally touching the micro switch 1;

[0080] When unlocking is required, the hidden handle 3 is manually pulled with force, and the trigger plate 4 is squeezed by the hidden handle 3, and the trigger plate 4 squeezes the stopper 52, so that the torsion spring 54 is compressed and reset under the action of the two ends of the torsion spring 54.

[0081] In this embodiment, as shown in the attached Figure 8 and attached Fig. 9 As shown, the protrusion limiting groove 23 is an arc-shaped groove, which cooperates with the fixed protrusion 55, and the protrusion limiting groove 23 extends from the inner top wall of the installation groove 22 in the direction away from the fixed protrusion 55, so as to facilitate the fixed protrusion 55 to be stuck into the protrusion limiting groove 23 under the action of inertia force and torsion spring 54.

[0082] In this embodiment, the matching groove 53 has two states. In the first state, the block 52 is in the initial state, and the top of the block 52 is supported on the inner top wall of the installation groove 22. At this time, the trigger plate 4 can rotate and trigger the micro switch 1 when the hidden handle 3 is opened; in the second state, the block 52 generates an inertial force to rotate in the direction of the base 2 after the car collides, and the block 52 rotates. At this time, the block 52 slides upward along the pin shaft 51 under the action of the torsion spring 54, that is, the matching groove 53 rises a certain distance. Relatively speaking, the rising of the matching groove 53 can reduce the rotation angle of the trigger plate 4, that is, the movement displacement of the trigger plate 4 becomes smaller, thereby limiting the outward rotation angle of the hidden handle 3, thereby preventing the hidden handle 3 from being accidentally opened and the door from being opened when the car collides, causing casualties in the car.

[0083] In this embodiment, as shown in the attached Figure 4 and attached Fig.10As shown, a matching rod 41 is provided on one side of the trigger plate 4 close to the base 2, and the matching rod 41 extends vertically along the side wall of the trigger plate 4 close to the base 2, and the extension length can be set according to the size of the matching slot 53; the matching rod 41 will also rotate and match with the matching slot 53 while the trigger plate 4 rotates; when the matching slot 53 is in the first state, the matching slot 53 is also used to limit the matching rod 41 to prevent the trigger plate 4 from rotating too much and being unable to be reset; when the matching slot 53 is in the second state, the arc spacing between the matching slot 53 and the matching rod 41 is shortened, thereby achieving the effect of limiting the rotation angle of the matching rod 41 and the trigger plate 4.

[0084] A return torsion spring is rotatably arranged on the rotating shaft connecting the trigger plate 4 and the base 2, one end of the return torsion spring is supported on the side wall of the base 2, and the other end is arranged in the trigger plate 4. Under the action of the return torsion spring, the trigger plate 4 rotates in the direction away from the stop block 52; at the same time, under the action of the return torsion spring, the trigger plate 4 approaches the hidden handle 3, and when the hidden handle 3 is opened outward under the action of a smaller inertial force, the trigger plate 4 can block the hidden handle 3 from opening under the action of the return torsion spring; through the return torsion spring, the door can be further prevented from opening due to the rotation of the hidden handle 3.

[0085] Openings 311 are formed on the side of the matching groove 53 away from the base 2 , the top of the matching groove 53 , and the side of the matching groove 53 close to the pin shaft 51 to facilitate matching with the matching rod 41 of the trigger plate 4 .

[0086] In this embodiment, as shown in the attached Figure 4 and attached Figure 7 As shown, the abutment portion 56 cooperates with the side wall of the mounting groove 22 to limit the stopper 52 from rotating toward a side away from the base 2 under the action of the torsion spring 54 .

[0087] Specifically, the mounting groove 22 is composed of a top plate, a bottom plate and a side plate extending vertically along the side of the base 2. The pin shaft 51 passes through the top plate and the bottom plate. The side plate of the mounting groove 22 is located on the side away from the trigger plate 4, and one end of the torsion spring 54 is supported on the side plate, and the other end is supported on the side of the stopper 52 close to the side plate. The abutment portion 56 is located on the side of the stopper 52 away from the trigger plate 4, and the abutment portion 56 abuts against the side plate of the mounting groove 22, thereby preventing the stopper 52 from rotating under the action of the torsion spring 54, thereby preventing it from cooperating with the matching rod 41 of the trigger plate 4.

[0088] When the car is driving, the car body will shake up and down; the block 52 is in contact with the top and bottom walls of the installation groove 22. During the installation process, there will be a gap between the block 52 and the top and bottom walls of the installation groove 22. When the car body shakes, the block 52 will also reciprocate and hit the top and bottom walls of the installation groove 22, thereby generating abnormal noise and affecting the comfort of the passengers.

[0089] In this embodiment, as shown in the attached Fig. 9 As shown, a shock-absorbing rib 24 is provided at the bottom of the mounting groove 22, that is, a shock-absorbing rib 24 is provided on the upper surface of the bottom plate of the mounting groove 22, and the top wall of the shock-absorbing rib 24 contacts the bottom wall of the stop block 52. At the same time, the shock-absorbing rib 24 is used to separate the bottom wall of the stop block 52 from the top wall of the bottom plate of the mounting portion.

[0090] By providing the shock absorbing ribs 24 on the upper surface of the bottom plate of the installation groove 22 and the shock absorbing ribs 24 and the stopper 52, the collision between the stopper 52 and the top plate and the bottom plate of the installation groove 22 caused by the shaking of the vehicle body can be effectively reduced.

[0091] Furthermore, the inner top wall of the mounting groove 22 is also provided with shock-absorbing ribs 24. By providing the shock-absorbing ribs 24 on the inner top wall and the inner bottom wall of the mounting groove 22, the contact surface of the stopper 52 and the mounting groove 22 are separated, thereby preventing abnormal noise from being generated between the stopper 52 and the mounting groove 22.
