Description

Technical Field

[0001] This utility model relates to the field of automotive door handle technology, and in particular to a push-to-unlock switch assembly. Background Technology

[0002] In the existing technology, the push switch assembly of semi-concealed handles usually uses a pressure plate or other pressing mechanism to press and trigger switching elements such as micro switches. However, due to different operating habits and pressing force of each person, it cannot be guaranteed that the switching element will be triggered every time when pressing different positions, and the pressing position needs to be adjusted, resulting in a poor operating experience. Utility Model Content

[0003] To address the issue of poor user experience in existing push-button switch components, this invention provides a push-button unlocking switch component that improves the user experience.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A push-to-unlock switch assembly, comprising:

[0006] The substrate is fixedly connected to the handle body of the car door handle.

[0007] Pressure plate, wherein the pressure plate moves relative to the substrate;

[0008] A push-button switch assembly is disposed between a base plate and a pressure plate;

[0009] A rigid connector is connected between a substrate and a pressure plate. The rigid connector is rotatably connected to the substrate, and both ends of the rigid connector are limited on the pressure plate so as to move with the pressure plate.

[0010] An elastic reset element is disposed between the substrate and the pressure plate.

[0011] Furthermore, the push-button switch assembly is positioned between the base plate and the pressure plate, and the elastic reset element is symmetrically arranged along the push-button switch assembly.

[0012] Furthermore, the push-button switch assembly includes a housing with openings at both ends and a switch element located inside the housing. One end of the housing is fixed or integrally formed with a soft rubber cap with protrusions at both ends, and the other end of the housing is provided with a sealing element.

[0013] Furthermore, the rigid connecting member is a rotating shaft, which extends along the length direction of the pressure plate.

[0014] Furthermore, the two ends of the rotating shaft are respectively connected to the two ends of the pressure plate along its length.

[0015] Furthermore, the pressure plate has slots on both sides, and the rotating shaft is locked in the slots and the two can rotate relative to each other.

[0016] Furthermore, the cross-section of the rotating shaft is circular, and the slot is a cylindrical groove adapted to the size of the rotating shaft.

[0017] Furthermore, the pressure plate is provided with several positioning ribs, and the top of the positioning ribs is provided with positioning protrusions. The base plate is provided with a slide for the positioning protrusions to slide along the Y direction. The base plate is provided with positioning parts arranged opposite to each other on both sides of the inlet of the slide. The positioning parts are provided with snap-fit ​​parts for locking the positioning protrusions. In the free state, the distance between the two snap-fit ​​parts is less than the width of the positioning protrusions, and at least one positioning part can be elastically deformed.

[0018] Furthermore, the positioning protrusion is a cylinder, and an arc-shaped positioning surface matching the size of the positioning protrusion is provided between the snap-fit ​​part and the slide rail, and the arc-shaped positioning surface is smoothly connected to the slide rail.

[0019] Furthermore, the length of the slide rail along the X direction is greater than the length of the positioning rib extending into the slide rail. The positioning rib has a sliding allowance along the X direction.

[0020] Beneficial effects:

[0021] (1) The push-type unlocking switch assembly of this utility model achieves the consistency of the overall action when the pressure plate is pressed by a rigid connecting piece connected to both ends of the pressure plate. No matter which position of the pressure plate is pressed, the pressure plate can be pressed down as a whole, thereby effectively triggering the switch element and improving the user experience.

[0022] (2) The rigid connecting part is a cylindrical rotating shaft, and the positioning ribs on the pressure plate have a gap with the slide on the base plate along the X direction. This leaves a certain deformation space for the pressure plate to prevent the pressure plate from being deformed by pressure and thus failing to ensure the consistency of movement.

[0023] (3) A cylinder is provided at the top of the positioning rib. The cylinder has an arc-shaped positioning surface to cooperate with it. On the one hand, it can restrict the position of the pressure plate along the Y direction; on the other hand, the cylinder can slide relative to the arc-shaped positioning surface with less sliding friction, thereby further preventing the pressure plate from being deformed by pressure.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0040] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0042] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0043] Example 1:

[0044] like Figures 1-6 This utility model discloses a push-button unlocking switch assembly, comprising a base plate 1, a pressure plate 2, a push-button switch assembly 3, and an elastic reset element 4. The base plate 1 is fixedly connected to the handle body 6 of a car door handle, and the pressure plate 2 moves relative to the base plate 1. The push-button switch assembly 3 is disposed between the base plate 1 and the pressure plate 2. A rigid connector is connected between the base plate 1 and the pressure plate 2, and the rigid connector is rotatably connected to the base plate 1. Both ends of the rigid connector are limited on the pressure plate 2, thereby moving with the pressure plate 2. The elastic reset element 4 is disposed between the base plate 1 and the pressure plate 2. The elastic reset element 4 may be, but is not limited to, a spring.

[0045] The push-button switch assembly 3 is positioned between the base plate 1 and the pressure plate 2, and the elastic reset element 4 is symmetrically arranged along the push-button switch assembly 3.

[0046] The push-button switch assembly 3 includes a housing with openings at both ends and a switch element located inside the housing. One end of the housing is fixed or integrally formed with a soft rubber cap with protrusions at both ends, and the other end of the housing is provided with a seal. The seal is optional, but not limited to, potting compound.

[0047] The rigid connecting component is a rotating shaft 5, which extends along the length of the pressure plate 2. Both ends of the rotating shaft 5 are connected to the two ends of the pressure plate 2 along its length. The pressure plate 2 has slots 201 on both sides, in which the rotating shaft 5 is engaged and can rotate relative to it. The rotating shaft 5 has a circular cross-section, and the slots 201 are cylindrical grooves adapted to the dimensions of the rotating shaft 5.

[0048] As one way to install the rotating shaft 5, in this embodiment, the movement of the rotating shaft is restricted and it can rotate relative to the substrate 1 by providing a number of pairs of retaining ribs on the substrate 1. The retaining ribs can be elastically deformed, so the rotating shaft 5 only needs to be inserted between the retaining ribs on both sides, which is simple to operate and low in cost.

[0049] The pressure plate 2 is provided with a plurality of positioning ribs 21, and the top of the positioning ribs 21 is provided with positioning protrusions 211. The center of the positioning protrusions 211 is arranged along the X direction. The base plate 1 is provided with a slide rail 11 for the positioning protrusions 211 to slide along the Y direction. The base plate 1 is provided with positioning parts 12 arranged opposite to each other on both sides of the inlet of the slide rail 11. The positioning parts 12 are provided with locking parts 121 for locking the positioning protrusions 211. In the free state, the distance between the two locking parts 121 is less than the width of the positioning protrusions 211, and at least one of the positioning parts 12 can be elastically deformed.

[0050] The positioning protrusion 211 is cylindrical. An arc-shaped positioning surface 122, matching the size of the positioning protrusion 211, is provided between the engaging part 121 and the slide rail 11. The arc-shaped positioning surface 122 smoothly connects with the slide rail 11, meaning that the positioning rib 21 cannot move along the Z direction, and the length of the slide rail 11 along the X direction is greater than the length of the positioning rib 21 extending into the slide rail 11. In other words, there is a gap C between the positioning rib 21 and the slide rail 11 along the X direction, providing a sliding allowance for the pressure plate 2 along the X direction to prevent deformation under pressure.

[0051] The push-to-unlock switch assembly of this utility model can be applied to, for example... Figure 7 The semi-concealed handle is shown. In a specific application, the base plate 1 is fixed inside the handle body 6. When a person extends their hand out of the handle body 6 and presses the pressure plate 2, the pressure plate 2 presses down and triggers the push-button switch assembly 3, sending unlock signals, etc.

[0052] The base plate 1 is provided with positioning posts, and the elastic reset element 4 is a spring sleeved on the positioning posts. The pressure plate 2 is provided with a sleeve, and the spring is housed in the sleeve. In this way, the stability of the elastic reset element 4 is ensured.

[0053] Example 2:

[0054] When the strength of pressure plate 2 is sufficiently high, it can achieve consistent movement even without allowing for movement margin along the X direction. The corresponding structure is as follows: Figures 8-11A limiting component is provided between the substrate 1 and the pressure plate. The limiting component includes an X-direction limiting component, which includes a first X-direction limiting surface 13 disposed on the substrate 1 and a second X-direction limiting surface 22 disposed on the pressure plate 2. The limiting component also includes a Z-direction limiting component, which includes a Z-direction limiting surface 14 disposed on the substrate 1 and a Z-direction limiting cylindrical surface 23 disposed on the pressure plate 2. Finally, the limiting component includes a Y-direction limiting component, which includes a hook 24 disposed on the pressure plate 2, and a hook groove 15 on the substrate 1 that mates with the hook 24.

[0055] The structure of the rotating shaft 5 in this embodiment is as follows: Figure 8 and Figure 11 As shown, the rotating shaft 5 is secured in the slots at both ends of the pressure plate 2. The other structures are the same as in Embodiment 1.

[0056] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
