[0002] Traditional semi-hidden door handles are unlocked mechanically or electronically; although both methods achieve the shape of a semi-hidden door handle, there are still defects in the system: the mechanical method reduces the technological sense of operation; the electronic method has the problem of over-reliance on the circuit system, and when a circuit failure occurs, the switch may fail.

[0003] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a door handle and a vehicle to solve the problems of weak technological sense of mechanical door handles and easy failure of electronic door handles in the prior art.

[0005] To achieve the above purpose, the present utility model adopts the following technical solutions:

[0006] On the one hand, the present utility model provides a door handle, including:

[0007] A first door handle mounting structure;

[0008] A second door handle mounting structure, including a first end, a second end and a third end connected to each other, the first end is movably connected to the first door handle mounting structure, the second end is used for rotatably connecting to a first connecting member on the door handle assembly, and a pressing plate is connected to the third end;

[0009] And a microswitch structure, which includes a door handle outer finish, a circuit board fixing bracket, at least two circuit boards and at least two microswitches from outside to inside in sequence. The door handle outer finish and the circuit board fixing bracket are both connected to the third end, and the circuit board fixing bracket, at least two of the circuit boards and at least two of the microswitches are connected in sequence; at least two of the microswitches can be turned on under the drive of the pressing plate;

[0010] An operation space is formed between the first door handle mounting structure and the second door handle mounting structure.

[0011] As a further preferred technical solution, the door handle outer finish covers the circuit board fixing bracket, the circuit board, the microswitch and the pressing plate in the horizontal direction.

[0012] As a further preferred technical solution, at least two second connecting members are connected between the third end and the pressing plate, and the longitudinal section of the pressing plate is rectangular.

[0013] As a further preferred technical solution, a rubber interlayer is provided between at least two of the second connectors.

[0014] As a further preferred technical solution, at least one second contact is provided on the microswitch, and at least one first contact matching the second contact is provided on the surface of the pressing plate.

[0015] As a further preferred technical solution, at least one second protection structure is provided on the surface of the circuit board fixing bracket, and at least one of the second contacts protrudes from at least one of the second protection structures;

[0016] At least one first protection structure matching the second protection structure is further provided on the surface of the pressing plate.

[0017] As a further preferred technical solution, a mounting groove is provided on the circuit board fixing bracket, and a mounting rib matching the mounting groove is provided at the third end.

[0020] On the other hand, the present invention provides a vehicle including a car door, and the above-mentioned door handle is provided on the car door.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The door handle provided by the present invention forms an operation space between the first door handle mounting structure and the second door handle mounting structure. When in use, the user inserts the hand into the operation space and gently presses the second door handle mounting structure outwards. The pressing plate on this structure moves to the position of the microswitch, thereby driving the microswitch itself to conduct. The signal required to open the car door can be transmitted to the vehicle controller through the circuit board, and the vehicle controller controls the car door to open, thus achieving the effect of electrically opening the car door. When the microswitch or the circuit board fails, the user needs to use greater force to pull the second door handle mounting structure. At this time, rotation occurs between the second end on the second door handle mounting structure and the first connector, driving the entire microswitch structure to rotate outwards, thereby achieving the effect of mechanically opening the car door.

[0023] Furthermore, the door handle is semi-hidden, with an aesthetically pleasing structure. The outer surface of the door handle covers the circuit board fixing bracket, circuit board, microswitch, and pressing plate in the horizontal direction, achieving a smaller occupied space. The third end of the second door handle mounting structure is connected to the pressing plate through a second connecting member, avoiding the use of a more complex and thicker pressing plate structure (such as a turning structure). Ultimately, the overall thickness of the microswitch structure, pressing plate, and the third end in contact with the pressing plate can be reduced to 12 mm.

[0024] Furthermore, by providing a water diversion groove and a drainage groove, the door handle avoids water accumulation in the structure, reduces the possibility of electronic unlocking failure, and also reduces structural corrosion, extending its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1

[0037] As Figures 1-6 shown, this embodiment provides a door handle, including:

[0038] The first door handle mounting structure 1;

[0039] The second door handle mounting structure 2 includes a first end 201, a second end 202, and a third end 203 that are connected to each other. The first end 201 is movably connected to the first door handle mounting structure 1. The second end 202 is used for rotatably connecting to a first connecting member on the door handle assembly. A pressing plate 204 is connected to the third end 203;

[0040] And a microswitch structure 3, which includes a door handle outer finish 301, a circuit board fixing bracket 302, two circuit boards 303, and two microswitches 304 from outside to inside in sequence. The circuit board fixing bracket 302, at least two circuit boards 303, and at least two microswitches 304 are connected in sequence; at least two microswitches 304 can be turned on under the drive of the pressing plate 204;

[0041] An operation space 4 is formed between the first door handle mounting structure 1 and the second door handle mounting structure 2.

[0042] The above operation space is used for the user to insert their hand into it so as to operate the door handle to open the door. Since the length of the operation space is about 105 mm, the number of the above circuit boards and microswitches is at least two to ensure that the operation signal is effectively received. In this embodiment, both the circuit board and the microswitch are set to two, and actually, they can also be set to three, four, etc.

[0043] The main function of the movable connection between the first door handle mounting structure and the second door handle mounting structure is to ensure that when the second door handle mounting structure rotates relative to the first connecting member, the second door handle mounting structure can be separated from the first door handle mounting structure. In this embodiment, no special limitation is imposed on the form of the above movable connection, and any implementable form in the art can be adopted. For example, a limiting structure is provided in the middle of the first door handle mounting structure, and the first end of the second door handle mounting structure can be arranged in the limiting structure, located in the limiting structure under normal conditions, and returning to the limiting structure when rotating and returning, while avoiding displacement.

[0044] It should be noted that the door handle in this embodiment only includes some components of the door handle assembly. Therefore, the second end is rotatably connected to the first connecting member on the door handle assembly.

[0045] It can be understood that the above first connecting member can realize the rotation / turning of the second door handle mounting structure and the microswitch structure. Optionally, the second end 202 is rotatably connected to the first connecting member on the door handle assembly through a spring 205 and a rotating shaft (not shown).

[0046] Optionally, the above second door handle mounting structure is integrally formed.

[0047] In an alternative embodiment, the outer finish 301 of the door handle covers the circuit board fixing bracket 302, the circuit board 303, the micro switch 304, and the pressing plate 204 in the horizontal direction. The above-mentioned outer finish of the door handle covers the circuit board fixing bracket, the circuit board, the micro switch, and the pressing plate in the horizontal direction. From the perspective of the front view, the height of the outer finish of the door handle is higher than the respective heights of the circuit board fixing bracket, the circuit board, the micro switch, and the pressing plate, and the circuit board fixing bracket, the circuit board, the micro switch, and the pressing plate behind the outer finish of the door handle cannot be seen. Such a design can reduce the volume of the overall structure of the door handle.

[0048] In an alternative embodiment, the third end 203 and the pressing plate 204 are connected by four second connecting members 206, and the longitudinal section of the pressing plate 204 is rectangular. In order to further reduce the thickness of the door handle, four second connecting members are provided between the third end and the pressing plate in this embodiment. The above-mentioned second connecting members can not only connect the third end and the pressing plate, but also enable the user's operating force to directly act on the pressing plate and then be transmitted to the micro switch. The longitudinal section of the pressing plate being rectangular is sufficient. Without the above-mentioned second connecting members, the shape of the pressing plate needs to be designed as a structure with protrusions or turns, and a greater force is required to transmit the force to the micro switch.

[0049] It should be noted that the number of the above-mentioned second connecting members is at least two. Four are used in this embodiment, and in addition, it can also be two, three, five, six, etc. The above-mentioned longitudinal section refers to the section perpendicular to the horizontal plane on the pressing plate after the door handle is installed on the vehicle.

[0050] In an alternative embodiment, a rubber interlayer 207 is provided between the four second connecting members 206. When manufacturing the door handle of this embodiment, the second door handle mounting structure (including the second connecting members and the pressing plate) is integrally formed, and there are gaps between the respective second connecting members to form a hollow structure, and then rubber is filled in the hollow structure to form the above-mentioned rubber interlayer, so that when the third end is pressed, the structure is more likely to deform, the acting force is appropriate, and when the user touches the rubber during operation, the user experience can be improved, and the waterproof performance can also be improved.

[0051] In an alternative embodiment, at least one second contact (not shown) is provided on the micro switch, and at least one first contact 2041 matching the second contact is provided on the surface of the pressing plate 204. The pressing plate and the micro switch are electrically connected through the contact between the mutually matching first contact and second contact. It can be understood that the above-mentioned matching means matching in position and size. By changing the distance between the first contact and the second contact, a more reasonable operating stroke can also be designed. For example, if the distance between the two is far, the operating stroke for conduction when pressed is long, and if the distance between the two is close, the operating stroke for conduction when pressed is short.

[0052] It should be noted that the above-mentioned first contact and second contact are each at least one. In this embodiment, two are adopted. In addition, it can also be one, three, four, five, etc.

[0053] In an alternative embodiment, at least one second protection structure 3021 is provided on the surface of the circuit board fixing bracket 302, and at least one of the second contacts (not shown) protrudes from at least one second protection structure 3021;

[0054] At least one first protection structure 2042 that cooperates with the second protection structure 3021 is further provided on the surface of the pressing plate 204.

[0055] After the microswitch is turned on in this embodiment, the first protection structure and the second protection structure come into contact, thereby preventing the force on the pressing plate from continuing to be applied to the microswitch, playing a role in protecting the microswitch. Among them, the second contact protrudes from the second protection structure, which can ensure that the first contact on the pressing plate first contacts the microswitch.

[0056] It should be noted that the above-mentioned first protection structure and second protection structure are each at least one. In this embodiment, three are adopted. In addition, it can also be one, two, four, five, etc.

[0057] In an alternative embodiment, an installation groove 3022 is provided on the circuit board fixing bracket 302, and an installation rib 2031 that matches the installation groove 3022 is provided at the third end 203. The installation groove 3022 and the installation rib 2031 are used to realize the connection between the circuit board fixing bracket 302 and the third end 203. In this embodiment, the connection between the circuit board fixing bracket and the third end is specifically realized through the installation groove on the circuit board fixing bracket and the installation rib on the third end. More specifically, in this embodiment, the installation groove and the installation rib are in interference fit to fix the circuit board fixing bracket to the third end. The connection method of the above two can be snap connection or welding.

[0058] Alternatively, a first snap portion is provided on the installation groove, and a second snap portion is provided on the installation rib. The first snap portion and the second snap portion cooperate to realize the snap connection between the circuit board fixing bracket and the third end.

[0059] In an alternative embodiment, a water diversion groove (not shown) is provided at the lower end of the circuit board fixing bracket, and a drainage groove (not shown) is provided at the lower end of the outer surface of the door handle. In this embodiment, a water diversion groove is provided at the lower end of the circuit board fixing bracket. After the door handle accidentally gets water, the water flowing through the circuit board fixing bracket can be introduced to the water diversion groove to protect the circuit board from getting water. The drainage groove at the lower end of the outer surface of the door handle can drain all the water at the water diversion groove and the water flowing in from other parts (such as the place where the second end is connected to the outer surface of the door handle) from the drainage groove.

[0060] Optionally, the outer finish of the above door handle is J-shaped.

[0061] In an alternative embodiment, two circuit boards 303 are connected by a wire 305. The main function of the circuit board is to conduct the on / off signals received by the micro switch. By connecting the two circuit boards with a wire, the signals can be transmitted to the corresponding control module in a timely manner to control the opening of the door.

[0062] Optionally, the circuit board is fixed to the circuit board fixing bracket through 4 card joints.

[0063] The above door handle forms an operation space between the first door handle mounting structure and the second door handle mounting structure. When in use, the user inserts the hand into this operation space and gently presses the second door handle mounting structure outwards. The pressing plate on this structure then moves to the position of the micro switch, thereby driving the micro switch itself to conduct. The signal required to open the door can then be transmitted to the vehicle controller through the circuit board, and the vehicle controller controls the opening of the door, thus achieving the effect of electrically opening the door. When the micro switch or the circuit board fails, the user needs to use greater force to pull the second door handle mounting structure. At this time, rotation occurs between the second end on the second door handle mounting structure and the first connecting piece, driving the entire micro switch structure to rotate outwards, thus achieving the effect of mechanically opening the door.

[0064] Furthermore, the door handle is semi-hidden, with an aesthetic structure. The outer finish of the door handle covers the circuit board fixing bracket, the circuit board, the micro switch, and the pressing plate in the horizontal direction, achieving a smaller occupied space. The third end of the second door handle mounting structure is connected to the pressing plate through a second connecting piece, avoiding the use of a more complex and thicker pressing plate structure (such as a turning structure). Ultimately, the overall thickness of the micro switch structure, the pressing plate, and the third end in contact with the pressing plate can be reduced to 12 mm.

[0065] Furthermore, by providing a water guiding groove and a drainage groove, the door handle avoids water accumulation in the structure, reduces the possibility of electronic unlocking failure, also reduces structure corrosion, and extends the service life.

It should be understood that the focus of this embodiment is on the application of this door handle, and no limitation is imposed on the specific connection method between this door handle and the door. Any implementable method in the art can be adopted.
