Description

Technical Field

[0001] The utility model belongs to the technical field of automobile interiors, and particularly relates to a flexible pressing structure with an integrated black appearance. Background Art

[0002] At present, with the development of technology, the technology of touch integrated black effect has been gradually applied to automobile interiors, such as the integrated black touch central control panel in automobiles. The traditional products with integrated black effect are usually realized by spraying paint on the soft layer and adding a support layer below. The overall structure is rigid, the surface cannot be deformed, and the operation requirements can only be achieved through touch sensors. The operation experience is poor, it is easy to distract the driver's attention during the operation, and it is easily affected by the external environment, such as temperature, water, etc., resulting in mis-touch or failure of the sensor. Summary of the Invention

[0003] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a flexible pressing structure with an integrated black appearance, which can realize mechanical pressing operation. While ensuring the integrated black appearance effect, the operation mode is adjusted to improve the operation experience of the operator, and solves the problems of poor pressing feel of the integrated black products and being easily affected by the outside.

[0004] The technical solution of the utility model: A flexible pressing structure with an integrated black appearance, including a support base and a circuit board arranged on the support base. A switch is electrically connected to the circuit board. A key for pressing the switch is arranged on the support base. The outer surface of the support base is covered with an integrated black film. The integrated black film sequentially includes a light-transmitting layer and a silica gel layer from outside to inside. The integrated black film has elasticity and is used to press the key and touch the switch after deformation. A reset structure is arranged between the key and the switch.

[0005] By adopting the above technical solution, by covering the support base with an elastic integrated black film, it is ensured that the appearance of the product is integrated black. After pressing the integrated black film to deform, it contacts and presses the key and squeezes the reset structure to touch the switch. After releasing, the key is reset under the action of the reset structure, and the switch is released, thereby realizing mechanical pressing operation for the product with an integrated black appearance. The operation feel is good, the staff is not easily affected by the outside, and the risk of mis-touch is effectively reduced.

[0006] The further setting of the utility model: An LED lamp is arranged on the circuit board, and a light-transmitting hole for the light of the LED lamp to pass through is arranged on the key.

[0007] By adopting the above further setting, the LED lamp can emit light. Part of the light is blocked by the opaque key, and the rest of the light is presented on the integrated black film after passing through the light-transmitting hole. By printing characters on the light-transmitting layer, it is clearly displayed on the integrated black film under the irradiation of the LED lamp.

[0008] Further setting of the present utility model: The thickness of the light-transmitting layer is 0.125 mm to 0.38 mm, the light transmittance of the light-transmitting layer is 1% to 98%, the thickness of the silica gel layer is 0.5 mm to 1.2 mm, and the light transmittance of the silica gel layer is 1% to 60%.

[0009] With the above further setting, the light-transmitting layer and the silica gel layer are prepared by processes such as ink printing, hot pressing, UV curing, and die cutting in the prior art. It has a soft touch. The silica gel layer can play a role in uniform light, enabling the LED light to be evenly distributed after irradiating the silica gel layer, reducing the phenomena of light spots and shadows, and improving the visual comfort and effect. By controlling the thickness and light transmittance of the light-transmitting layer, the number of photons allowed to pass through is changed to change the brightness of the light-transmitting layer and highlight the characters printed on the light-transmitting layer.

[0010] Further setting of the present utility model: The thickness of the support base is 1.5 mm to 2.5 mm.

[0011] With the above further setting, the support base provides support for the light-transmitting layer and the silica gel layer. By reasonably controlling the thickness, while saving material costs, it avoids deforming together with the integrated black film when pressed, plays a supporting role, and makes the pressing operation feel better.

[0012] Further setting of the present utility model: The reset structure is a rubber layer provided on the circuit board, and the rubber layer has a shell-shaped convex structure above the switch.

[0013] With the above further setting, the rubber layer has the functions of waterproof and elasticity. It is provided on the circuit board and can prevent the circuit board from getting water to a certain extent. And it is set as a shell-shaped convex structure above the switch. After its deformation, compared with a single rubber layer, it has a greater elastic force to reset the button.

[0014] Further setting of the present utility model: The button and the support base are relatively slid through the snap connection of convex columns and grooves, and the shaking of the button in the horizontal direction is restricted.

[0015] With the above further setting, through the cooperation of the convex columns and the card slots, the button and the support base are restricted to slide in one direction, preventing the button from shaking in other directions and enhancing the stability of the button.

[0020] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] It should be noted that in the description of the present utility model, all directional indications (such as up, down, front, back...) are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0022] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. In the description of the present utility model, the meaning of "several" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] As Figure 1 shown, a flexible pressing structure with an integrated black color includes a support base 1 and an integrated black film 5. At least one button unit can be provided on the support base 1. As Figures 2-3 shown, a circuit board 2 is provided at the bottom of the support base 1. Each button unit includes a switch 3 electrically connected to the circuit board 2 and a button 4 provided on the support base 1 for pressing the switch 3.

[0024] Each button 4 and the support base 1 are respectively provided with corresponding convex columns and grooves for snap connection to realize the relative sliding of the button 4 and the support base 1 in the pressing direction, and to limit the shaking of the button 4 in other directions, enhancing the stability of the button 4.

[0025] The integrated black film 5 is covered on the outer surface of the support base 1, making the appearance of the product integrally black. The integrated black film 5 sequentially includes a light-transmitting layer 6 and a silica gel layer 7 from outside to inside. The integrated black film 5 has elasticity. A reset structure 8 is provided between each key 4 and the corresponding switch 3. After the integrated black film 5 is deformed by pressing, the integrated black film 5 contacts and presses the key 4 to act, so as to squeeze the reset structure 8 to trigger the switch 3. After releasing, the key 4 is reset under the action of the reset structure 8, and the switch is released, thereby realizing a mechanical pressing operation on the product with an integrated black appearance. The operation feel is good, making it difficult for the staff to be interfered by the outside world and effectively reducing the risk of accidental touch.

[0026] The reset structure 8 is a rubber layer fixedly arranged on the circuit board 2 with a waterproof function, which can prevent the circuit board 2 from getting water to a certain extent. And the rubber layer is in a shell-shaped convex structure above the switch 3, specifically a hemispherical shell structure. After the rubber layer is deformed, compared with a single rubber layer, the rubber layer with a hemispherical shell structure has greater elasticity to reset the key 4.

[0027] An LED lamp 9 is provided on the circuit board 2, and a light-transmitting hole 10 for the light of the LED lamp 9 to pass through is provided on the key 4. Part of the light emitted by the LED lamp 9 is blocked by the opaque key 4, and the remaining light is presented on the integrated black film 5 through the light-transmitting hole 10. And characters are printed on the light-transmitting layer 6 and are clearly displayed on the integrated black film 5 after being irradiated by the LED lamp 9, prompting the operator of the function corresponding to this key 4.

[0028] The thickness of the silica gel layer 7 is 0.5 mm to 1.2 mm, and the light transmittance of the silica gel layer 7 is 1% to 60%. It can block part of the light, making the light irradiated on the light-transmitting layer 6 by the LED lamp 9 softer. And because silica gel has good optical properties and can play a role in light homogenization, the light of the LED lamp 9 is evenly distributed inside the silica gel layer 7. Selecting a thickness of 0.5 mm to 1.2 mm enables the light to be reflected and refracted more times inside the silica gel layer 7, so that the light is evenly dispersed, reducing the light spots and shadows concentrated at specific points and forming a more uniform lighting effect. Then the light is conducted to the light-transmitting layer 6 through the silica gel layer 7;

[0029] The thickness of the light-transmitting layer 6 can be 0.125 mm to 0.38 mm, and the light transmittance of the light-transmitting layer 6 is 1% to 98%. By controlling the thickness and light transmittance of the light-transmitting layer 6, the number of photons allowed to pass through is changed to change the brightness of the light-transmitting layer 6. And characters with a lower light transmittance are printed on the light-transmitting layer 6, which can prominently display the characters and prompt the function of the key 4 here.

[0030] The light-transmitting layer 6 and the silica gel layer 7 can be obtained through processes such as ink printing, hot pressing, UV curing, and die-cutting in the prior art. They have a soft touch and can play a role in light homogenization, enabling the LED lamp 9 to be more evenly distributed after irradiating the integrated black film 5, reducing the phenomena of light spots and shadows, and improving the visual comfort and effect.

[0031] The thickness of the support base 1 can be set to 1.5 mm to 2.5 mm, providing support for the light-transmitting layer 6 and the silica gel layer 7, and reasonably controlling the thickness to avoid deforming together with the integrated black film 5 during pressing, playing a supporting role and making the pressing operation feel better.
