Description

Technical Field

[0001] The utility model relates to the technical field of automobile handles, in particular to a novel hidden handle with an emergency opening mechanism. Background Art

[0002] With the development of the automobile industry, considering the aesthetics and practicality, hidden car handles are more and more widely used. The existing hidden handles (in two forms, push and rotate) are generally flush with the door sheet metal. The handle is connected to the bracket system. The bracket system has a motor and a control mechanism for driving the handle to open. There are also springs for resetting the handle after the door is opened and a counterweight for collision safety. Under normal circumstances, the handle is driven by the motor to pop out, and then the user can pull the handle to unlock and open the door. However, once the car battery is dead or the temperature is low and the handle is frozen by ice and snow, the handle cannot pop out automatically, and it is difficult for users to directly pull the handle to unlock and open the door like operating system handles. For example, the utility model patent with publication number CN16397973A discloses a mechanical push-type hidden door handle, car door and vehicle. When the handle is frozen by ice and snow, the commonly used treatment method is to first drive the handle to break the ice through a motor. If the motor power is not enough to drive the handle to break the ice layer, the user needs to remove the ice layer on the surface of the handle first. When the whole vehicle has no electricity or the electronic components fail, the common emergency unlocking method is to press the front end of the handle vigorously to apply force (i.e., the end of the Z axis in the direction of the front of the vehicle and close to the middle area of ​​the handle). The handle will rotate around the Z axis of the middle area of ​​the handle to make the tail end tilt up (similar to the form of a seesaw). At this time, the user grabs the tilted tail end of the handle and pulls the handle to unlock and open the door. However, due to the appearance, space and structural limitations, the distance from the rotating shaft to the front end of the handle (i.e., the force application position of the user's emergency opening) is very small, that is, the force arm is very small, and the user needs to apply a lot of force with his fingers to turn the handle, and the user's comfort is poor. Utility Model Content

[0003] The utility model aims to provide a novel hidden handle with an emergency opening mechanism, which is used to solve the technical problem that when the hidden automobile handle in the prior art fails to open automatically, it is difficult to open it manually and is prone to being unable to open.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A new type of hidden handle containing an emergency opening mechanism comprises a handle body, on which an opening mechanism is arranged, the opening mechanism comprises a limiting portion located on the handle body and a force-applying portion cooperating with the limiting portion to allow the distal end of the handle body to have a tendency to rotate along the rotating axis, an integrated handle cover or a split handle cover is installed on the surface of the handle body, and the force-applying portion and the handle cover are separately arranged or connected.

[0006] Furthermore, the limiting portion is configured as a socket on the handle cover, and the inner cavity of the handle body is configured to be colinear with the socket and to cooperate with an extension hole for inserting the force-applying portion. An elastic blocking portion is also installed between the extension hole and the socket. The elastic blocking portion blocks the connection line between the extension hole and the socket in a non-stressed state, and the elastic blocking portion is deformed to avoid the connection line between the extension hole and the socket in a stressed state. The angle α between the center line of the socket and the extension hole and the handle body is an obtuse angle. The force-applying portion is configured as a slender piece that is inserted into and cooperates with the socket and the extension hole. The inner cavity of the handle body is provided with a mounting groove for installing the elastic blocking portion, and the mounting groove is integrally formed with the handle or can be detachably installed or formed by welding.

[0007] Furthermore, the limiting portion is configured as an avoidance hole recessed from the handle cover into the handle body, one end of the force-applying portion is rotatably connected to the end of the handle body, an installation is provided between the force-applying portion and the handle body to make the force-applying portion have a tendency to reset from the open position to the closed position, the force-applying portion is embedded in the avoidance hole when in the closed position, and the force-applying portion is rotated along the axis to form an angle with the handle body when in the open position, the length of the force-applying portion is smaller than the length of the avoidance hole, a supporting platform for supporting and limiting the force-applying portion when in the closed position is provided in the avoidance hole, the supporting platform is integrally formed with the handle body, the connecting surface of the end of the avoidance hole away from the force-applying portion and the base of the supporting platform is an arc surface, and a snap-on connection is provided between the force-applying end of the force-applying portion and the supporting platform.

[0008] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:

[0009] (1) The utility model is conducive to realizing that when the hidden car handle cannot be opened automatically, the opening mechanism can be used to apply force to the distal end of the handle body to make it have a tendency to rotate. Since the distal end is farther from the rotation axis, according to the principle of lever, the user only needs to use a small force to pull out the handle, and the force can be reduced to 10%-20% of the original emergency opening pressure value according to the length of the force arm, thereby realizing the manual opening of the hidden car handle and improving the operating experience; the above-mentioned operation method greatly reduces the operating force, so the torque of the return spring in the system can be increased without changing the operating force, and the collision safety of the vehicle can be effectively guaranteed, and the reliability of the whole vehicle system can be improved. At the same time, reducing the spring torque is also conducive to reducing the weight of the counterweight, thereby saving materials and realizing lightweighting of the whole vehicle;

[0010] (2) The utility model provides an opening mechanism as a plug hole and a force-applying part that is inserted into and matched with the plug hole. The force-applying part can be replaced by any slender member around it. The operation is convenient and fast, and it is convenient to quickly open the faulty car handle. By providing an elastic blocking part, the connection between the plug hole and the extension hole is blocked under normal conditions, which is not only good for appearance but also good for preventing debris from entering. When the handle needs to be opened due to a fault, the force-applying part enters the plug hole and can quickly avoid entering the extension hole to achieve manual opening. When the force-applying part withdraws, the elastic blocking part rebounds to the original position at the connection between the plug hole and the extension hole;

[0011] (3) The utility model provides an opening mechanism as an avoidance hole and a force-applying part installed at one end of the avoidance hole, and connects the force-applying part to the end of the handle body. Under normal conditions, the force-applying part is embedded in the avoidance hole. When manual force is required to open the handle, a finger is inserted into the avoidance hole to act on the force-applying end of the force-applying part to rotate and pull up the force-applying end, thereby driving the handle body to perform an opening operation on the handle.

[0025] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the utility model is further described below in conjunction with the drawings and embodiments.

[0026] The use scenario targeted by the utility model is: when the battery is dead or the electronic components fail, the operation method in the prior art is to press the proximal end 300 of the handle hard to make the distal end 104 tilt up, but this operation method is laborious and still prone to the situation that the handle cannot be opened. The technical solution disclosed by the utility model is to improve the structural design of the hidden car handle in the prior art in view of the above situation to overcome the above defects. The schematic diagram of the car handle in the prior art is shown in the attached figure. Figure 1 .

[0027] Embodiment 1

[0028] See attached Figure 2-4 A new type of hidden handle with an emergency opening mechanism includes a handle body 100. The handle body 100 can realize a rotational movement through a rotating shaft 200. The end closer to the rotating shaft 200 is a proximal end 300, and the end farther from the rotating shaft 200 is a distal end 104. Compared with the distal end 104, the proximal end 300 is closer to the front direction of the vehicle. An integrated handle cover 400 is installed on the surface of the handle body 100, that is, the handle cover 400 and the handle body 100 are integrally formed. An opening mechanism is arranged on the handle body 100. The mechanism includes a limiting portion located on the handle body 100 and a force-applying portion 600 that cooperates with the limiting portion to make the distal end 104 of the handle body 100 have a tendency to rotate along the rotating shaft 200. Specifically, the force-applying portion 600 and the handle cover 400 are separately arranged, that is, the force-applying portion 600 has no connection with the handle body 100 in a normal state, and the limiting portion is arranged as a socket 401 on the handle cover 400, where the socket 401 is a through hole that penetrates the handle cover 400, and the inner cavity of the handle body 100 is arranged in a colinear line with the socket 401 and is used to cooperate with the force-applying portion 600. The extension hole 102 through which the force part 600 is inserted can be integrally injection molded with the handle body 100 or a detachable part installed on the inner cavity of the handle. An elastic stopper 500 is also installed between the extension hole 102 and the plug hole 401. The elastic stopper 500 blocks the line connecting the extension hole 102 and the plug hole 401 in a non-stressed state, and the elastic stopper 500 deforms to avoid the line connecting the extension hole 102 and the plug hole 401 in a stressed state. The elastic stopper 500 is made of rubber material, and the inner cavity of the handle body 100 is provided with a The installation groove 101 for installing the elastic blocking part 500 is formed integrally with the handle or can be detachably installed or welded. The elastic blocking part 500 is provided with a clamping part and a retaining edge. The clamping part is used to be clamped on the installation groove 101, and the retaining edge is used to block the insertion hole 401 and the extension hole 102. However, when the retaining edge is subjected to force, it bends and deforms to facilitate the force-applying part 600 to pass through the insertion hole 401 and enter the extension hole 102. Here, an avoidance platform is provided at the entrance of the extension hole 102. The avoidance platform is used to provide space for the bent retaining edge to avoid the force-applying part 600. In addition, the angle α between the center line of the insertion hole 401 and the extension hole 102 and the handle body 100 (here, the plane where the handle cover 400 is located) is an obtuse angle, see the attached Figure 4 Here, the obtuse angle range is 95°-175°, preferably 150°. The force-applying portion 600 is configured as a slender piece that is inserted into and matched with the socket 401 and the extension hole 102. It can be any rod-shaped object or a key-shaped object or any other slender shape that can be inserted into the socket 401 and the extension hole 102.

[0029] When the hidden handle cannot be opened normally due to abnormal conditions such as freezing or power failure, a key or other slender force-applying part 600 is used to enter the extension hole 102 along the insertion hole 401. At this time, the retaining edge of the elastic retaining part 500 is bent to the avoidance platform by the force. The user applies force to the end of the force-applying part 600 exposed outside the handle body 100 to lift the handle body 100 and rotate it, thereby completing the manual operation to open it. When the force-applying part 600 is pulled out, the retaining edge of the elastic retaining part 500 returns to its original position under the action of its own elasticity to separate the insertion hole 401 from the extension hole 102.

[0030] Embodiment 2

[0031] See attached Figure 5 and 6A new type of hidden handle with an emergency opening mechanism includes a handle body 100, the handle body 100 can realize a rotational action through a rotating shaft 200, the end closer to the rotating shaft 200 is a proximal end 300, and the end farther from the rotating shaft 200 is a distal end 104, a split handle cover 400 is installed on the surface of the handle body 100, that is, the handle cover 400 and the handle body 100 are detachably installed, and an opening mechanism is arranged on the handle body 100, and the opening mechanism includes The limiting part on the handle body 100 and the force applying part 600 that cooperates with the limiting part to make the distal end 104 of the handle body 100 have a tendency to rotate along the rotating shaft 200. Specifically, the force applying part 600 and the handle cover 400 are connected, that is, the force applying part 600 is installed on the handle cover 400 of the handle body 100, and the limiting part is set as an avoidance hole 700 recessed from the handle cover 400 into the handle body 100. One end of the force applying part 600 is connected to the handle body 100. The end portion is rotatably connected, where one end of the force-applying portion 600 is rotatably connected to the distal end 104 of the handle body 100 via an axis, and a member is installed between the force-applying portion 600 and the handle body 100 to allow the force-applying portion 600 to have a tendency to reset from the open position to the closed position. Specifically, when the force-applying portion 600 is in the closed position, it is embedded in the avoidance hole 700, and when the force-applying portion 600 is in the open position, it rotates along the axis and forms an angle with the handle body 100. Here, the closed position is that the force-applying portion 600 is horizontally embedded. It is in a non-use state in the avoidance hole 700, and is in a use state in the open position, that is, when the force-applying part 600 rotates along the axis and forms a certain angle with the handle body 100. The length of the force-applying part 600 is smaller than the length of the avoidance hole 700, and a supporting platform 103 is provided in the avoidance hole 700 for supporting and limiting the force-applying part 600 in the closed position. Specifically, the supporting platform 103 is integrally formed with the handle body 100, and the supporting platform 103 is used to support and limit the force-applying part 600 in the closed position. The connecting surface between the end of the avoidance hole 700 away from the force-applying part 600 and the base of the supporting platform 103 is an arc surface 701. The arc surface 701 is not only beautiful, but also helps to prevent the accumulation of debris and avoid accidental injury to the user's fingers during operation. A snap connection is set between the force-applying end 601 of the force-applying part 600 and the supporting platform 103. The snap connection is a conventional connection structure in the prior art, so it is not designed in detail in the accompanying drawings. The snap connection here can ensure that the force-applying part 600 is embedded in the avoidance hole 700 when not in use, and the force-applying end 601 of the force-applying part 600 is separated from the supporting platform 103 when in use. The outer surface of the force-applying part 600 can be set as an anti-slip layer with relatively good anti-slip performance. The protective layer can adopt a detachable anti-slip sleeve or a concave and convex anti-slip shape formed by processing the force-applying part 600 body, or the force-applying end 601 of the force-applying part 600 can be provided with a through pulling hole, which is convenient for operating force during use.

[0032] When the above-mentioned hidden handle cannot be opened normally due to abnormal conditions such as freezing or power failure, the user's finger acts on the force-applying end 601 of the force-applying part 600 along the avoidance hole 700, and the force-applying part 600 is separated from the supporting platform 103. After the force-applying part 600 is rotated along the axis to a certain angle, the force-applying part 600 is operated to drive the handle body 100 to rotate to complete the manual opening action.

[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
