Description

Technical Field

[0001] The present application relates to the technical field of handle structures, and in particular to a hidden door handle structure. Background Art

[0002] With the rapid development of science and technology, the modern automobile industry is changing with each passing day. New processes, new materials and new technologies are widely used. In particular, the collision and integration of electronic technology and traditional machinery have made the automobile industry develop in the direction of automation and intelligence. The combination of traditional car door handles and electronic technology has given rise to hidden car door handles.

[0003] The traditional straight-pull door handle is higher than the door sheet metal, which destroys the streamlined shape of the entire vehicle. It is not only unsightly, but also has large wind resistance and cannot meet the needs of the existing market. Summary of the invention

[0004] The purpose of the present application is to provide a hidden door handle structure, aiming to solve the technical problem that the traditional straight-pull door handle cannot be extended or retracted.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] The present application provides a hidden door handle structure, comprising:

[0007] The handle body comprises a shell and a handle member, wherein the handle member has a first mounting portion and a second mounting portion which are spaced apart from each other;

[0008] A first driving member is disposed in the housing, and the first driving member has a first connecting end hinged to the housing and a second connecting end hinged to the first mounting portion;

[0009] A second driving member is disposed in the housing, and the second driving member has a first hinged end hinged to the housing and a second hinged end hinged to the second mounting portion;

[0010] an actuator, at least a part of which is disposed in the housing, the actuator having a first actuator end abutting against the first driving member and a second actuator end abutting against the second driving member, so that when the actuator is working, the first driving member rotates around the first connecting end, and the second driving member rotates around the first hinge end, and at least a part of which is horizontally exposed outside the housing;

[0011] Wherein, the rotation direction of the first driving member is configured as the rotation direction of the second driving member, and the first driving member rotates synchronously with the second driving member.

[0012] In the above technical solution, the first actuator end of the actuator abuts against the first driving member, and the second actuator end of the actuator abuts against the second driving member, so that when the actuator is working, it can drive the first driving member and the second driving member to move simultaneously, and make the handle member exposed from the shell, satisfying the user's operation of opening the car door.

[0013] Further, the second driving member includes a follower member coaxially arranged with the unlocking arm and a first follower arm limitedly connected to the follower, one side of the follower member abuts against the second executing end, at least a portion of the structure of the first follower arm is exposed from the follower, the exposed structure of the first follower arm is configured as a side of the follower away from the second executing end, and the exposed structure of the first follower arm is hinged to the handle member.

[0014] In the above technical solution, the follower rotates under the action of the second actuator end so that the side of the follower close to the second actuator end first contacts the first follower arm, and the first follower arm moves together under the action of the follower, finally realizing the door opening operation.

[0015] Furthermore, the follower includes a follower cam and a first lock, the follower cam is provided with a limit groove slidably connected to the first follower arm, and the first follower arm has an avoidance groove adapted to the first lock, so that when the first follower arm slides relative to the follower cam, the first lock forms an abutment against the avoidance groove.

[0016] In the above technical solution, the limiting groove of the driven cam can limit the first driven arm during the rotation process, and drive the first driven arm to rotate along its rotation direction. During the rotation of the first driven arm, its avoidance groove can abut against the first lock buckle, so that under the action of the user, the door can be opened through the unlocking arm, which improves the appearance of the car and effectively reduces the wind resistance of the car in the form of overshoot.

[0017] Furthermore, the second driving member includes a first follower rod abutting against the second execution end, a second follower arm, and a second lock catch coaxially arranged with the unlocking arm, one end of the second follower arm is configured to be hinged to the first follower rod, and the other end of the second follower arm is configured to be hinged to the second mounting portion of the handle member, so that when the handle member is exposed to the shell, the second lock catch abuts against the first follower rod.

[0018] In the above technical solution, the first driven rod rotates under the action of the second actuator end, thereby driving the second driven arm to rotate. In the process of the handle being exposed from the shell, the second lock buckle gradually forms a snap connection with the first driven rod. Finally, under the action of the user, the second lock buckle rotates together with the unlocking arm to realize the door opening operation, which improves the appearance of the car and effectively reduces the wind resistance of the car in the form of overshoot.

[0019] Further, a first abutting portion adapted to the second lock catch is protruded on one side of the first driven rod close to the second driven arm, and a protruding direction of the first abutting portion is configured as a vertical direction of the first driven rod.

One end of the third follower arm is hinged to a side of the second follower rod away from the third lock, and the other end of the third follower arm is hinged to the handle member, so that when the handle member is exposed from the shell, the third lock is abutted against the second follower rod.

[0022] In the above technical solution, the second follower rod rotates under the action of the second actuator end, thereby driving the third follower arm to rotate. Under the action of the user, the third lock buckle is driven to rotate through the second follower rod, thereby realizing the rotation of the unlocking arm and completing the door opening operation, thereby improving the appearance of the car and effectively reducing the wind resistance of the car in the form of overshoot.

[0023] Furthermore, a second abutting portion is protruded from the second driven rod, and a protruding direction of the second abutting portion is configured to be a vertical direction of the second driven rod.

[0024] In the above technical solution, by providing a second abutment portion adapted to the third lock catch on the second driven rod, the third lock catch can be driven to rotate together with the second driven rod during rotation, thereby realizing the rotation of the unlocking arm and completing the operation of opening the door.

[0026] In the above technical solution, by providing a front roller at one end of the push rod and a rear roller at the other end of the push rod, when the actuator works, the first driving member and the second driving member can be rotated synchronously.

[0027] Furthermore, the actuator includes an actuator and a push rod connected to the actuator. One end of the push rod close to the actuator protrudes with a first actuator portion that abuts against the first driving member, and the other end of the push rod away from the actuator protrudes with a second actuator portion that abuts against the second driving member.

[0028] In the above technical solution, by providing a first actuator portion at one end of the push rod and a second actuator portion at the other end of the push rod, when the actuator works, the first driving member and the second driving member can be rotated synchronously.

[0029] Furthermore, the first actuator end is configured on the side of the first driving member away from the first mounting portion, and the second actuator end is configured on the side of the second driving member away from the second mounting portion.

[0030] In the above technical solution, by arranging the first actuator end and the second actuator end on the same side of the handle member, when the actuator works, the handle member can be horizontally exposed outside the housing, ensuring the appearance of the car door.

[0031] Compared with the prior art, the beneficial effect of the solution of the present application is that the first actuator end of the actuator abuts against the first driving member, and the second actuator end of the actuator abuts against the second driving member.

[0050] Embodiment

[0051] As Figure 1 shown, Figure 1It is a schematic structural diagram of a hidden door handle structure disclosed in an embodiment of the present application. The present application provides a hidden door handle structure, including: a handle main body 100, a first driving member 200, a second driving member 300, and an actuator 400. The first driving member 200 and the second driving member 300 are both arranged on the same side of the handle main body 100. The execution end of the actuator 400 is used to correspondingly drive the first driving member 200 and the second driving member 300, so that the first driving member 200 and the second driving member 300 can rotate synchronously through the actuator 400, and the handle member 102 of the handle main body 100 is horizontally exposed outside the housing 101 of the handle main body 100.

[0052] Exemplarily, the hidden door handle structure can be installed on the outer door of an automobile. It can be in the application scenarios of other doors. Taking the installation on the outer door of an automobile as an example, the first driving member 200, the second driving member 300, and the actuator 400 can all be installed on the outer door of the automobile through the handle main body 100. And an opening groove corresponding to the handle member 102 of the handle main body 100 is provided on the outer door of the automobile. When the hidden door handle structure is hidden in the outer door of the automobile, the handle member 102 can be set to be flush with the outer door of the automobile to ensure the appearance of the automobile. When the door needs to be opened, the actuator 400 works. Under the action of the actuator 400, the first driving member 200 and the second driving member 300 drive the handle member 102 to be horizontally exposed outside the housing 101 and protrude from the door. After the actuator 400 completes the maximum stroke, the user applies an external force on the side of the handle member 102 close to the second driving member 300 to open the door.

[0053] As Figure 1 shown, the handle main body 100 in the present application includes a housing 101 and a handle member 102, and the handle member 102 has a first mounting portion 1021 and a second mounting portion 1022 which are arranged at intervals.

[0054] Exemplarily, the housing 101 has a receiving cavity. Both the first driving member 200 and the second driving member 300 are arranged in the receiving cavity. At least a part of the structure of the actuator 400 is arranged in the receiving cavity. The receiving cavity has an opening for avoiding the handle member 102. Mounting ears are arranged at intervals on the periphery of the housing 101 for mounting the hidden door handle structure on the car door.

[0055] It can be understood that the first mounting portion 1021 is located on the left side of the handle member 102, the second mounting portion 1022 is located on the right side of the handle member 102, and the length direction of the handle member 102 is configured to be the length direction of the housing 101. The actuator 400, the first driving member 200, and the second driving member 300 are arranged along the length direction of the housing 101.

[0056] As Figure 2 shown, Figure 2 is a cross-sectional view of a hidden door handle structure disclosed in an embodiment of the present application. The first driving member 200 in the present application is configured to be inside the housing 101, and the first driving member 200 has a first connection end 201 hinged to the housing 101 and a second connection end 202 hinged to the first mounting portion 1021 of the handle member 102.

[0057] Exemplarily, the first driving member 200 includes, but is not limited to, a driving arm. The first connection end 201 is located on the left side of the first driving member 200, the second connection end 202 is located on the right side of the first driving member 200, and the first connection end 201 is connected to the housing 101 through a first pin shaft, and a first return spring 600 is sleeved on the first pin shaft; the second connection end 202 is connected to the first mounting portion 1021 of the handle member 102 through a second pin shaft, and a second return spring 700 is sleeved on the second pin shaft. Under the combined action of the first return spring 600 and the second return spring 700, when the actuator 400 retracts, the handle member 102 can return to a position flush with the housing 101; both the first return spring 600 and the second return spring 700 are flat double torsion springs, which can ensure the uniformity of the gap between the handle member 102 and the vehicle door during the extension and reset processes.

[0058] It should be noted that the first actuator end of the actuator 400 abuts against the left side of the first driving member 200, and the second actuator end of the actuator 400 abuts against the left side of the second driving member 300. When the first actuator end is the front roller 4021 and the second actuator end is the rear roller 4022, in order to reduce the friction and noise existing in the motion transmission process, grease can be applied to the contact position between the left side of the first driving member 200 and the front roller 4021, and grease can be applied to the contact position between the left side of the second driving member 300 and the rear roller 4022. In order to extend the service life of the grease and ensure the transmission durability of the first driving member 200 and the second driving member 300, a plurality of grease groove structures can be provided at the contact position between the first driving member 200 and the front roller 4021, and at the contact position between the second driving member 300 and the rear roller 4022. The shape of the grease groove is not specifically limited, as long as it corresponds to the execution trajectory of the first actuator end and the execution trajectory of the second actuator end.

[0059] For example Figure 2 As shown, the second driving member 300 in the present application is disposed in the housing 101 , and the second driving member 300 has a first hinged end hinged to the housing 101 and a second hinged end hinged to the second mounting portion 1022 .

[0060] Exemplarily, the second driving member 300 is spaced apart from the first driving member 200, and the second driving member 300 is arranged on the side of the first driving member 200 away from the actuator 401 of the actuator 400, and the second driving member 300 is coaxially arranged with the unlocking arm 500, so that the second driving member 300 drives the rotation of the unlocking arm 500 under the action of the second actuator end of the actuator 400, and the unlocking arm 500 pulls the car door lock through the door zipper to realize the process of opening the door.

[0061] like Figure 3 As shown, Figure 3 It is a structural schematic diagram of a second driving member 300 of a hidden door handle structure disclosed in an embodiment of the present application, wherein the second driving member 300 includes a follower member 301 coaxially arranged with an unlocking arm 500 and a first follower arm 302 limitedly connected to the follower member 301, one side of the follower member 301 abuts against the second execution end, at least a portion of the structure of the first follower arm 302 is exposed from the follower 301, the exposed structure of the first follower arm 302 is configured as a side of the follower 301 away from the second execution end, and the exposed structure of the first follower arm 302 is hinged to the handle member 102.

[0062] Exemplarily, the follower 301 is coaxially arranged with the unlocking arm 500 through a fixing pin. The fixing pin is rotatably connected to the housing 101, and the follower 301, the unlocking arm 500, and the first follower arm 302 rotate around the fixing pin.

[0063] In the above technical solution, the follower 301 rotates under the action of the second execution end, so that the side of the follower 301 close to the second execution end first contacts the first follower arm 302, and the first follower arm 302 moves together under the action of the follower 301, finally realizing the door opening operation.

[0064] For another example Figure 2 or Figure 3 As shown, the follower 301 includes a follower cam 3011 and a first latch 3012. The follower cam 3011 is provided with a limiting groove 3013 slidably connected to the first follower arm 302. The first follower arm 302 has an avoidance groove 3021 adapted to the first latch 3012, so that when the first follower arm 302 slides relative to the follower cam 3011, the first latch 3012 forms an abutment against the avoidance groove 3021.

[0065] Exemplarily, the follower cam 3011 can be set as a sector, a circle, a square, etc., as long as it can ensure the normal operation of the follower arm and the first latch 3012 during the rotation of the follower cam 3011.

[0066] Wherein, when the driven cam 3011 is arranged in a sector shape, the arc segment of the driven cam 3011 is located on the side of the driven cam 3011 away from the handle member 102, and the driven cam 3011 is provided with a slot for accommodating at least a part of the structure of the first driven arm 302 and the first latch 3012. The limiting grooves 3013 are arranged on both the upper and lower sides of the driven cam 3011, and the limiting grooves 3013 communicate with the slot. The upper and lower sides of the first driven arm 302 are provided with ejector pins disposed in the limiting grooves 3013. It can be understood that the length direction of the limiting groove 3013 is configured to be the length direction of the avoidance groove 3021. The limiting grooves 3013 are distributed along the execution direction of the actuator 401 of the actuator 400, and the limiting grooves 3013 can be arranged in an arc shape so that when the driven cam 3011 rotates, the first latch 3012 can form an abutment with the avoidance groove 3021. At this time, the handle member 102 is horizontally exposed outside the housing 101. When opening the vehicle door, a user applies an external force near the second mounting portion 1022 of the handle member 102, and the ejector pin moves from the side of the avoidance groove 3021 close to the second execution end of the actuator 400 to the side of the avoidance groove 3021 away from the second execution end of the actuator 400 (that is, the ejector pin moves from Figure 2 the left side of the driven cam 3011 in Figure 2 to the right side of the driven cam 3011), and drives the unlocking arm 500 to rotate through the first latch 3012, realizing the opening of the vehicle door.

[0067] In the above technical solution, the limiting groove 3013 of the driven cam 3011 can limit the first driven arm 302 during rotation and drive the first driven arm 302 to rotate along its rotation direction. During the rotation of the first driven arm 302, its avoidance groove 3021 can form an abutment with the first latch 3012, so that under the action of the user, the vehicle door can be opened through the unlocking arm 500, improving the appearance of the vehicle and effectively reducing the wind resistance of the vehicle during driving.

[0068] As Figure 4 shown, Figure 4It is a structural schematic diagram of a driven cam 3011 and a first driven arm 302 of a hidden door handle structure disclosed in an embodiment of the present application; when the handle member 102 is in a horizontal position exposed to the shell 101 and the user pulls the handle member 102 outward, the handle member 102 will shake up and down due to the influence of gravity and the downward force of the hand. In order not to affect the movement of its internal structure, the driven cam 3011 is provided with a first rib structure 3014 on the upper and lower sides, which can be used to abut the inner side of the shell 101, and the first driven arm 302 is provided with a second rib structure 3022 on the upper and lower sides, and a plurality of the second rib structures 3022 are arranged at intervals, wherein the second rib structure 3022 corresponding to the driven cam 3011 is used to abut the driven cam 3011, and the second rib structure 3022 corresponding to the shell 101 is used to abut the shell 101.

[0069] like Figure 5 As shown, Figure 5 It is a structural schematic diagram of an embodiment of a hidden door handle structure disclosed in the present application, the second driving member 300 includes a first follower rod 303 abutting against the second execution end, a second follower arm 304 and a second lock buckle 305 coaxially arranged with the unlocking arm 500, one end of the second follower arm 304 is configured to be hinged to the first follower rod 303, and the other end of the second follower arm 304 is configured to be hinged to the second mounting portion 1022 of the handle member 102, so that when the handle member 102 is exposed from the shell 101, the second lock buckle 305 abuts against the first follower rod 303.

[0070] Exemplarily, the second actuator end is configured as a side of the first follower rod 303 facing away from the handle member 102, one end of the first follower rod 303 is hinged to the housing 101 via a third pin, the other end of the first follower rod 303 is hinged to one end of the second follower arm 304 via a fourth pin, the other end of the second follower arm 304 is hinged to the second mounting portion 1022 of the handle member 102 via a fifth pin, and the second lock buckle 305 is arranged between the first follower rod 303 and the handle member 102.

[0071] It is understandable that the second latch 305 is coaxially connected to the unlocking arm 500 through a fastening pin. In order to ensure that the car door can be automatically locked when the user disengages from the handle member 102, a third return spring 800 is provided at the position where the unlocking arm 500 is exposed from the housing 101. The third return spring 800 includes but is not limited to a torsion spring, and the third return spring 800 has a first free end and a second free end. The first free end abuts against the unlocking arm 500, and the second free end abuts against the housing 101. It should be noted that when the handle member 102 is exposed outside the housing 101, the third return spring 800 has a certain torsional force.

[0072] In the above technical solution, the first driven rod 303 rotates under the action of the second execution end, and then drives the second driven arm 304 to rotate. During the process of the handle member being exposed outside the housing 101, the second latch 305 gradually engages with the first driven rod 303. Finally, under the action of the user, the second latch 305 and the unlocking arm 500 rotate together to realize the door opening operation, which improves the appearance of the car and effectively reduces the wind resistance of the car during driving.

[0073] As Figure 6 shown, Figure 6 FIG. is a schematic connection diagram of the second latch 305 and the first driven rod 303 of a hidden door handle structure disclosed in an embodiment of the present application. A first abutting portion adapted to the second latch 305 is convexly provided on one side of the first driven rod 303 close to the second driven arm 304, and the protruding direction of the first abutting portion is configured as the vertical direction of the first driven rod 303.

[0074] Exemplarily, when the handle member 102 is just horizontally exposed outside the housing 101, the second latch 305 just abuts against the first abutting portion. When the user holds the handle member 102 and applies an external force, after the second latch 305 rotates a certain angle along with the first driven rod 303, the unlocking arm 500 also rotates along with the second latch 305, thereby completing the opening of the car door.

[0075] In the above technical solution, by providing the first abutting portion adapted to the second latch 305 on the first driven rod 303, it is possible to drive the second latch 305 to rotate together during the rotation of the first driven rod 303, and then realize the rotation of the unlocking arm 500 to complete the operation of opening the car door.

[0076] As Figure 7 shown, Figure 7This is a schematic structural diagram of another embodiment of a hidden door handle structure disclosed in the present application, the second driving member 300 includes a third follower arm 307, a third lock catch 308 and a second follower rod 306 abutting against the second execution end, the second follower rod 306, the third lock catch 308 and the unlocking arm 500 are coaxially arranged, one end of the third follower arm 307 is hinged to the side of the second follower rod 306 away from the third lock catch 308, and the other end of the third follower arm 307 is hinged to the handle member 102, so that when the handle member 102 is exposed from the shell 101, the third lock catch 308 forms an abutment with the second follower rod 306.

[0077] Exemplarily, one end of the second follower rod 306 and the third lock catch 308 are hinged to the shell 101 through the unlocking arm 500, and the other end of the second follower rod 306 is hinged to one side of the third follower arm 307, and the other side of the third follower arm 307 is hinged to the second mounting portion 1022 of the handle member 102, wherein one end of the second follower rod 306 can be arranged between the third lock catch 308 and the unlocking arm 500, and one end of the second follower rod 306 can also be arranged on the side of the third lock catch 308 away from the unlocking arm 500, and the third lock catch 308 can be fixed to the unlocking arm 500 by a fixing pin, so that after the second follower rod 306 contacts the third lock catch 308, the second follower rod 306, the third lock catch 308 and the unlocking arm 500 can be rotated synchronously.

[0078] In the above technical solution, the second follower rod 306 rotates under the action of the second execution end, thereby driving the third follower arm 307 to rotate, and under the action of the user, the third lock buckle 308 is driven to rotate through the second follower rod 306, thereby realizing the rotation of the unlocking arm 500, completing the operation of opening the door, improving the appearance of the car, and effectively reducing the wind resistance of the car in the form of overshoot.

[0079] For example Figure 7 As shown, a second abutting portion is protruded from the second driven rod 306 , and the protruding direction of the second abutting portion is configured to be the vertical direction of the second driven rod 306 .

[0080] In the above technical solution, by setting a second abutment portion adapted to the third lock buckle 308 on the second driven rod 306, the third lock buckle 308 can be driven to rotate together during the rotation of the second driven rod 306, thereby realizing the rotation of the unlocking arm 500 and completing the operation of opening the vehicle door.

[0081] For example Figure 2As shown, at least a part of the structure of the actuator 400 in the present application is configured within the housing 101. The actuator 400 has a first execution end that abuts against the first driver 200 and a second execution end that abuts against the second driver 300. When the actuator 400 operates, the first driver 200 rotates around the first connection end 201, and the second driver 300 rotates around the first hinge end. At least a part of the structure of the handle member 102 is horizontally exposed outside the housing 101. The first execution end is configured on the side of the first driver 200 away from the first mounting portion 1021, and the second execution end is configured on the side of the second driver 300 away from the second mounting portion 1022. By arranging the first execution end and the second execution end on the same side of the handle member 102, when the actuator 400 operates, the handle member 102 can be horizontally exposed outside the housing 101, ensuring the appearance of the vehicle door.

[0082] Wherein, the rotation direction of the first driver 200 is configured to be the same as that of the second driver 300, and the first driver 200 and the second driver 300 rotate synchronously.

[0083] Exemplarily, the actuator 400 can be installed inside the housing 101 or outside the housing 101. The execution directions of the first execution end and the second execution end of the actuator 400 are the same, and the execution directions of the first execution end and the second execution end are configured to be the length direction of the housing 101. When the actuator 400 executes to the maximum displacement, the handle member 102 is horizontally exposed outside the housing 101.

[0084] In the above technical solution, the first execution end of the actuator 400 abuts against the first driver 200, and the second execution end of the actuator 400 abuts against the second driver 300. When the actuator 400 operates, it can drive the first driver 200 and the second driver 300 to move simultaneously, and the handle member 102 is exposed outside the housing 101, satisfying the user's operation of opening the vehicle door.

[0085] As Figure 8 shown, Figure 8 is an exploded view of a hidden door handle structure disclosed in an embodiment of the present application. The actuator 400 includes an actuator 401 and a push rod 402 connected to the actuator 401. A front roller 4021 that abuts against the first driver 200 is arranged at one end of the push rod 402 close to the actuator 401, and a rear roller 4022 that abuts against the second driver 300 is arranged at the other end of the push rod 402 away from the actuator 401. The rotation direction of the front roller 4021 is configured to be the same as that of the rear roller 4022.

[0086] In the above technical solution, by providing a front roller 4021 at one end of the push rod 402 and a rear roller 4022 at the other end of the push rod 402, when the actuator 401 works, the first driving member 200 and the second driving member 300 can be rotated synchronously.

[0087] For another example Figure 2 、 Figure 5 、 Figure 7 As shown, the actuator 400 includes an actuator 401 and a push rod 402 connected to the actuator 401. One end of the push rod 402 close to the actuator 401 protrudes with a first actuator portion that abuts against the first driving member 200, and the other end of the push rod 402 away from the actuator 401 protrudes with a second actuator portion that abuts against the second driving member 300.

[0088] In the above technical solution, by providing a first actuator portion at one end of the push rod 402 and a second actuator portion at the other end of the push rod 402, when the actuator 401 works, the first driving member 200 and the second driving member 300 can be rotated synchronously.

[0089] Exemplarily, when the handle member 102 is in the extended state, that is, after the vehicle receives the signal to open the handle member 102, the circuit of the actuator 401 of the actuator 400 is turned on. The first actuator end and the second actuator end of the push rod 402 correspondingly drive the first driving member 200 and the second driving member 300 to move forward. Finally, the handle member 102 is horizontally exposed outside the housing 101. To achieve the door opening action, the user needs to further manually operate, that is, the user places the hand on the side of the handle member 102 close to the second mounting portion 1022 and pulls the handle member 102 outward forcefully. After the handle member 102 is pulled, the second mounting portion 1022 will move outward and drive the unlocking arm 500 to rotate, so that the door pull chain fixed on the upper part of the unlocking arm 500 is pulled, and finally the door lock is opened; when the door opening action is completed, the user's hand will leave the handle member 102. At this time, the third return spring 800 is in a twisted state. After the hand is released, the handle member 102 will return to the position horizontally exposed to the housing 101. Furthermore, the actuator 401 of the actuator 400 performs a contraction action, driving the push rod 402 to return to the original position. At this time, since the first return spring 600 and the second return spring 700 are in a twisted state, under the action of the first return spring 600 and the second return spring 700, the first driving member 200 and the second driving member 300 will be driven to return to the original state, thus completing the hiding of the handle member 102 in the housing 101.

[0090] Please refer to Figure 9 、Figure 10 During the process of pushing out the handle member 102, the actuator 401 needs to overcome the torsional forces of the first return spring 600 and the second return spring 700 simultaneously. Among them, during the design process, the second return spring can provide a return force for the second mounting portion of the handle member 102. In order to ensure that the handle member 102 can be smoothly reset after being extended and has a certain pre-tightening force at the reset position, it is required that the first return spring 600 and the second return spring 700 have a large return force. However, the increase in the return force of the first return spring 600 and the second return spring 700 will further increase the pushing resistance of the actuator 401.

[0091] In order to reduce the pushing resistance of the actuator 401, in one of the solutions, the second return spring 700 will be cancelled and a fourth return spring 900 will be added. The fourth return spring 900 is sleeved on the first latch 3012 or the second latch 305 or the third latch 308. Taking the first latch 3012 as an example, the first free end of the fourth return spring 900 abuts against the claw surface of the first latch 3012, and the second free end of the fourth return spring 900 abuts against the first driven arm 302. Compared with the second return spring 600, the fourth return spring 900 is closer to the second mounting portion of the handle member 102. Therefore, the fourth return spring 900 can use a smaller torque to reset the second mounting portion of the handle member 102.

[0092] Specifically, when the handle member 102 is in the hidden state, to prevent the loosening of each part, the fourth return spring 900 is in a preliminary torsional state. When the handle member 102 is in the process of being extended, the first driven arm 302 will push the fourth return spring 900 to twist. At this time, since the first latch 3012 is connected to the unlocking arm 500 and the upper part of the unlocking arm 500 has a third return spring 800, under the reaction force of the third return spring 800, the first latch 3012 is in a stationary state. At this time, the end of the fourth return spring 900 that abuts against the claw surface of the first latch 3012 will remain stationary. And when the user pulls the handle member 102 by hand, the fourth return spring 900 will rotate synchronously with the first driven arm 302 and the first latch 3012 at the same time. When the handle member 102 needs to be reset, due to the fourth return spring 900 being in a torsional state, based on the acting force of the fourth return spring 900, the relevant components of the handle member 102 will perform a reset operation.

[0093] It should be noted that when the car is in a power-off or low-power state, the function of the hidden door handle structure will not be able to be used normally. In order to ensure that the user can normally open the door in this state, the user uses his hand to press the handle member 102 inward on the side close to the first mounting portion 1021. The handle member 102 will use its hinge with the first drive member 200 as the rotation point, and then tilt the second mounting portion 1022 to move outward. At this time, the user uses his hand to hold the vicinity of the second mounting portion 1022, and realizes the door opening operation by adapting the car door key to the keyhole.

[0094] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For technical users in the field, the present application may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
