Technical Field
[0001] This utility model relates to the technical field of automotive parts, and in particular to an unlocking structure for an automotive door handle. Background Technology
[0002] Passenger cars are becoming increasingly common as a means of transportation. A passenger car is composed of a complex and diverse set of components, among which door handles are one. With the development of the passenger car industry, people have increasingly higher requirements for the operation of car door handles.
[0003] Especially in the increasingly common new energy vehicles, flat or swing-out handles are usually used. Sensors are installed inside the handle to unlock the door. When the user places their hand on the handle and presses the activation part, the sensor inside the handle receives the activation signal, thereby opening the door.
[0004] However, existing sensor handles have certain drawbacks: the small operating interface of the activation part results in low sensitivity, requiring repeated pressing and poor user comfort; pressing the activation part causes deformation of the handle shell, resulting in a short lifespan for the handle. Utility Model Content
[0005] In order to solve the above-mentioned problems in the prior art, the present invention provides an unlocking structure for a car door handle.
[0006] The above-mentioned problems of this utility model are solved by the following technical solution:
[0007] An unlocking structure for a car door handle includes,
[0008] A handle that is rigidly connected to the car door, wherein the handle is provided with a mounting groove that communicates with the internal cavity of the handle;
[0009] The bracket includes at least a pressing surface, which is embedded in the mounting groove of the handle and has the same surface as the handle. When subjected to external force, at least part of the pressing surface is displaced toward the cavity side.
[0010] The activator, located inside the bracket, moves synchronously with the pressing surface;
[0011] The sensor is located inside the handle and corresponds to the position of the activator, receiving the activation signal from the activator.
[0012] A further setting of the above technical solution is that the pressing surface is made of PP material.
[0013] A further setting of the above technical solution is: the displacement stroke of the pressing surface is 0.2~0.5mm.
[0014] A further provision of the above technical solution is that the bracket also includes an abutment edge integrally formed with the pressing surface, the abutment edge being arranged around the pressing surface and extending toward the handle cavity side to form an abutment with the inner wall of the handle cavity.
[0015] A further provision of the above technical solution is as follows: a bent portion is provided in the middle of the abutting edge, the receiving groove formed by the bracket forms a connecting deformation area and a receiving area on both sides of the bent portion, the bent portion forms a limiting surface on the back of the deformation area, and the sensing element is installed on the limiting surface.
[0016] A further configuration of the above technical solution is as follows: the handle includes a front panel and a handle base, and the abutting edge of the bracket abuts against the inner wall of the panel.
[0017] By adopting the above technical solution, the bent part of the bracket forms a limiting surface to ensure the precise alignment of the sensing element and the activating element; the abutting edge and the abutting foot of the inner wall of the panel form point contact, which ensures the support strength without affecting the deformation under pressure.
[0018] A further provision of the above technical solution is that: an abutment foot is provided on the inner wall of the panel, and the abutment edge contacts and abuts the abutment foot.
[0019] By adopting the above technical solution, through the abutment design between the bracket abutment edge and the inner wall of the handle, and the soft material cushioning of the deformable parts, only the pressing surface produces local micro-displacement when pressed, avoiding deformation of the entire handle shell, reducing structural stress concentration, and significantly improving long-term durability.
[0020] A further provision of the above technical solution is that it also includes a deformable component, wherein the deformable component is edged on the outer periphery of the pressing surface and connected to the groove wall of the mounting groove.
[0021] By adopting the above technical solution, the deformable part is firmly connected to the activator part through two-color injection molding, the reset performance is stable, the overall structure design is compact and the assembly precision is high.
[0022] A further provision of the above technical solution is that the deformable part is made of a soft material.
[0023] By adopting the above technical solution, the soft deformable part adopts a ring-shaped edge structure, which provides uniform buffering while ensuring the stability of the activator during movement, further improving the environmental adaptability and operational consistency of the unlocking structure.
[0024] A further provision of the above technical solution is that: a stepped end face is provided on the outer periphery of the deformable part to abut against the inner wall of the handle, and the main body of the deformable part is located between the activator and the groove wall of the mounting groove.
[0025] Compared with the prior art, the beneficial effects of this utility model are as follows: it directly uses deformable PP material as the pressing surface and embeds it in the mounting groove, which is consistent with the surface of the handle, thus increasing the operating interface area; at the same time, the deformation of the pressing surface drives the activation element to move, and with the high sensitivity of the sensing element, the user does not need to press repeatedly to trigger unlocking, which effectively improves the user experience.

[0040] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0041] like Figure 1-7 As shown in the figure, this embodiment discloses an unlocking structure for a car door handle.
[0042] Example 1
[0043] An unlocking structure for a car door handle 100 includes,
[0044] A handle 100 rigidly connected to the car door, wherein the handle 100 is provided with a mounting groove 102 communicating with the internal cavity of the handle 100;
[0045] The bracket 200 includes at least a pressing surface 210, which is embedded in the mounting groove 102 of the handle 100 and has the same surface as the handle 100. When subjected to external force, at least part of the pressing surface 210 is displaced toward the cavity side.
[0046] The activator 300 is located inside the bracket 200 and moves synchronously with the pressing surface 210.
[0047] The sensor is located inside the handle 100 and corresponds to the position of the activator 300, and receives the activation signal from the activator 300.
[0048] The above is the basic scheme of this embodiment.
[0049] In this embodiment, the handle 100 is a flat-out handle 100 found on new energy vehicles, as detailed below. Figure 1 As shown, a handle groove 101 is provided on the handle 100. When unlocking, the handle 100 is moved horizontally to the outside of the car door, and a person's hand is inserted into the handle groove 101 to unlock the handle 100.
[0050] The mounting groove 102 is provided on the outer groove wall of the handle groove 101. When a finger is inserted into the handle groove 101, the palm faces the outer groove wall, so that force can be applied to the pressing surface 210 in the mounting groove 102.
[0051] When the pressing surface 210 is squeezed by an external force, it is displaced towards the cavity side of the handle 100, which drives the activator 300 to move synchronously, causing the activator 300 to move closer to the sensor in the cavity of the handle 100. The sensor receives the activation signal and opens the car door.
[0052] In this embodiment, the sensing element is a sensing part disposed on the PCB board 400.
[0053] In this embodiment, the activator 300 is a metal sheet.
[0054] In this embodiment, the pressing surface 210 is made of PP material.
[0055] PP, or polypropylene, is a thermoplastic resin produced by polymerizing propylene. It has high impact resistance, strong mechanical properties, and resistance to various organic solvents and acid and alkali corrosion.
[0056] Meanwhile, PP material has a certain deformation capacity. That is, when pressure is applied to the middle part of the pressing surface 210, the middle part deforms towards the cavity side of the handle 100, so that the activator 300 is close to the sensor. After the external force is removed, the deformed part is reset, and the activator 300 is moved away from the sensor.
[0057] The displacement stroke of the pressing surface 210 is 0.2~0.5mm.
[0058] Typically, the sensors used in automobiles are highly sensitive and can receive activation signals as soon as they enter the sensing range. Therefore, the pressing surface 210 only needs to undergo a very small displacement or deformation to bring the activator 300 into the sensing range of the sensor.
[0059] In order to support the pressing surface 210 and ensure its reset capability, in this embodiment, the bracket 200 further includes an abutment edge 220 integrally formed with the pressing surface 210. The abutment edge 220 is arranged around the pressing surface 210 and extends toward the cavity side of the handle 100 to form an abutment with the inner wall of the cavity of the handle 100.
[0060] Specific reference Figure 2 and Figure 3 As shown, the abutting edge 220 surrounds the outer periphery of the pressing surface 210, forming an integral structure with the pressing surface 210, and a receiving groove with an opening is formed on the back of the pressing surface 210 for mounting components such as the PCB board 400.
[0061] Meanwhile, the handle 100 includes a panel 110 exposed on the door and a handle seat 120 embedded in the door. The mounting groove 102 is located on one side of the handle seat 120, and the end of the abutting edge 220 abuts against the inner wall of the panel 110, thereby exposing the pressing surface 210 into the mounting groove 102.
[0062] In this embodiment, a bending portion 221 is provided in the middle part of the abutment edge 220, and the receiving groove formed by the bracket 200 forms a connecting deformation area a and a receiving area b on both sides of the bending portion 221. The bending portion 221 forms a limiting surface 221.1 on the back of the deformation area a, and the sensing element is installed on the limiting surface 221.1.
[0063] Due to the bending portion 221, the receiving groove forms two deformation areas a and receiving areas b with different dimensions, and the length and width of the receiving area b are both greater than those of the deformation area a. Therefore, a limiting surface 221.1 is formed on the back of the deformation area a, which extends into the receiving area b. The sensor is installed in the receiving area b, and due to the restriction of the limiting surface 221.1, the sensor cannot enter the receiving area b, thereby ensuring the distance between the sensor and the activator 300. When the activator 300 is not close, the sensor cannot sense the activation signal.
[0064] Furthermore, in this embodiment, a guide post 230 is formed on the limiting surface 221.1, and a guide groove is provided on the PCB board 400 to accommodate the guide post 230 passing through.
[0065] Preferably, in this embodiment, the inner wall of the panel 110 is provided with an abutment foot 111, and the abutment edge 220 contacts and abuts the abutment foot 111.
[0066] Based on the above configuration, the contact area between the abutment edge 220 and the panel 110 is reduced. In other words, a point contact or a small surface contact is formed between the abutment edge 220 and the abutment foot 111, which facilitates the deformation of the bracket 200 under pressure, thereby ensuring the movement of the activator 300.
[0067] Example 2
[0068] The purpose of this embodiment is to provide another connection method between the bracket 200 and the handle 100. The specific implementation method is as follows:
[0069] It also includes a deformable part 500, which is disposed around the outer periphery of the pressing surface 210 and connected to the groove wall of the mounting groove 102.
[0070] Specific reference Figure 5 As shown, in this embodiment, in order to ensure the consistency of the activator 300, the deformable member 500 is set as a ring structure and is arranged on the outer periphery of the activator 300 in a rim-like manner. During the movement of the activator 300, it applies force evenly to the outer deformable member 500, thereby making the deformable member 500 have uniform micro-deformation.
[0071] Specifically, the deformable part 500 is made of a soft material.
[0072] Preferably, in this embodiment, the deformable part 500 is preferably a soft rubber, and in order to ensure the connection between the activator 300 and the deformable part 500, the activator 300 in this embodiment is made of hard rubber, such as plastic, and the soft rubber and hard rubber are molded by two-color injection molding to ensure that the connection between the activator 300 and the deformable part 500 is firm.
[0073] In this embodiment, the specific structure of the deformable part 500 is set as follows: the outer periphery of the deformable part 500 is provided with a stepped end face 510 that abuts against the inner wall of the handle 100, and the main body of the deformable part 500 is located between the activator 300 and the groove wall of the mounting groove 102.
[0074] Specific reference Figure 6 and Figure 7 As shown, the main body of the deformable part 500 is a ring structure, and the activator 300 is located in the inner ring of the deformable part 500 so that the deformable part 500 is clamped between the activator 300 and the groove wall of the mounting groove 102. When the activator 300 makes a micro-movement, the main body of the deformable part 500 undergoes a micro-deformation.
[0075] Meanwhile, the outer ring of the annular structure is provided with a stepped end face 510, which is used to connect with the inner wall of the handle 100 and attach to the inner wall of the edge of the mounting groove 102, thereby fixing the deformable part 500 and the handle 100.
[0076] There is a bend between the step end face 510 and the main body of the deformable part 500. When the activator 300 moves slightly toward the cavity of the handle 100, the bend of the deformable part 500 is bent and deformed, thereby ensuring that the activator 300 remains fixed to the deformable part 500 when it moves.
[0077] After the car door is opened, the pressure on the activator 300 is removed, and the deformable part 500 resets under the action of the removed external force, which in turn drives the activator 300 to reset.
[0078] In this embodiment, a mounting shell 600 is provided between the PCB board 400 and the activator 300 for mounting the PCB board 400.
[0079] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
