Description

Technical Field

[0001] This utility model relates to the field of touch structure technology, and in particular to a three-dimensional touch structure. Background Technology

[0002] Conventional touch screens are commonly used in black appliances, white appliances such as refrigerators and washing machines, and kitchen appliances such as induction cookers, ovens, dishwashers, and range hoods. They permeate almost all aspects of people's lives, work, and entertainment. At the same time, with the continuous upgrading of touch screens, consumers have increasingly higher expectations for the display and touch experience of products.

[0003] Chinese Patent Publication No.: CN 218568016 U, Publication Date: March 3, 2023. This utility model discloses an intelligent touchscreen structure, including a frame, a control board, a touchscreen, an insulating board, and a support assembly. The frame forms a cavity with an installation opening; the control board is disposed within the cavity; the touchscreen is installed at the installation opening and electrically connected to the control board; the insulating board is installed within the cavity and located between the control board and the touchscreen; the support assembly includes a first support member and a second support member. The first support member is disposed on the insulating board and movably abuts against one surface of the control board, and the second support member is installed on the first support member and movably abuts against the other surface of the control board to fix the control board within the frame. The shortcomings of this technical solution are: depending on the arrangement of the touch structure, the touch panel requires the operator to keep the front facing the screen for accurate operation. Otherwise, the operator needs to stand up and adjust their body position or bend their hand to operate, or they cannot operate due to limited side vision. This results in operation being limited to one side, making the operation method simple and inconvenient, reducing operation efficiency and interactive user experience.

[0004] In summary, touch-based structures suffer from drawbacks such as limited operation methods and inconvenience for multi-directional operation, which reduces operational efficiency and interactive experience. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of existing touch structures, such as limited operation modes and inconvenience for multi-directional operation, which reduces operation efficiency and interactive experience. It provides a three-dimensional touch structure that enables multi-directional operation and thus improves operation efficiency and interactive experience.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A three-dimensional touch structure, including A support frame is provided, and a connecting diaphragm is inserted into the support frame. One end of the connecting diaphragm is connected to a surface touch diaphragm, and the other end of the connecting diaphragm is connected to a side touch diaphragm. The decorative main panel has a surface groove on one end of the support frame. The decorative main panel is connected to the surface groove, and the surface touch film is connected to the decorative main panel. The decorative side panel has a side groove on the side of the support frame, the decorative side panel is connected to the side groove, and the side touch film is connected to the decorative side panel. The PCB board has a mounting groove on the other end face of the support frame. The PCB board is in the mounting groove and is bolted to the support frame. The front touch film and the side touch film are both electrically connected to the PCB board. The backplate assembly is snapped into the support frame, and there is space between the backplate assembly and the PCB board. The backplate assembly is equipped with heat dissipation holes and mounting holes.

[0007] The support frame is a rectangular support structure. The front touch film and decorative main panel are fixed in the groove on the end face of the support frame, while the side touch film and decorative side panel are fixed in the groove on the side face of the support frame. Connecting films link the front and side touch films together as a whole and electrically connect them to the PCB board in the mounting groove below the support frame. This allows for touch control on both the end face and sides of the touch structure, enabling multi-faceted, three-dimensional touch interaction regardless of whether the device has multiple end faces, multiple sides, or a combination of end faces and sides. This improves the device's interaction efficiency and enhances the user experience. The backplate assembly is mounted on the support frame as a connector for device assembly, facilitating later assembly via mounting holes. It also provides efficient heat dissipation for internal electronic components through the isolation space and ventilation holes, ensuring the long-term durability of the three-dimensional touch structure. The overall effect is multi-directional, three-dimensional touch interaction, improved operability, enhanced interaction efficiency and user experience, easy and quick assembly of components, and good heat dissipation extending service life.

[0008] Preferably, the surface groove has a connecting port, into which the connecting diaphragm is inserted. The side groove is connected to the surface groove through the connecting port, and the opening size of the connecting port is larger than the size and thickness of the side touch diaphragm. The connecting port is located at the bottom edge of the surface groove, allowing the support frame to pass through the opening and onto the connecting diaphragm. This facilitates quick insertion of the side touch diaphragm through the side connecting port during installation, further improving assembly efficiency.

[0009] Preferably, the support frame is connected to a positioning block, and the side touch diaphragm has a positioning groove that matches the size and position of the positioning block. The positioning block engages with the positioning groove. The positioning block is connected to the slot of the support frame near the side groove, allowing the side touch diaphragm to pass through the connecting opening and then be engaged with the positioning block through the positioning groove. This positions the side touch diaphragm within the side groove, facilitating its later connection with the decorative side panel. This further ensures stable connections between components and facilitates assembly.

[0010] Preferably, the mounting slot has a limiting groove on its wall, and the backplate assembly includes a protective plate. A locking block is connected to the wall of the limiting groove, and the protective plate has a locking slot. The locking block engages with the locking slot, and the protective plate is in contact with the other side of the limiting groove wall. A heat dissipation hole is included, located on the protective plate. The mounting slot wall engages with the locking slot of the protective plate via the locking block of the limiting groove's vertical rod, allowing the protective plate to be quickly connected within the limiting groove and its end face to abut against the end face of the limiting groove. This ensures stable and accurate positioning of the protective plate while maintaining sufficient isolation space between it and the PCB board. This achieves improved assembly efficiency and stability, and ensures high heat dissipation performance.

[0011] Preferably, the backplate assembly includes a mounting plate, a locking block two connected to the groove wall of the limiting groove, a locking slot two on the mounting plate, and a heat dissipation hole two. Assembly holes and the heat dissipation hole two are located on the mounting plate. The mounting plate is quickly installed in the limiting groove through the engagement of the locking block two and the locking slot two, preparing it for installation with the equipment via the assembly hole on the outermost side of the support frame. Additionally, the heat dissipation hole two provides heat dissipation for electronic components. This achieves the effect of ensuring rapid and stable assembly of components and good heat dissipation performance.

[0012] Preferably, the mounting plate is connected to a second positioning block. The bottom of the limiting groove has a second positioning groove that matches the size and position of the second positioning block, and the second positioning block and the second positioning groove are inserted into each other. The mounting plate is connected to a second positioning block that corresponds to the position of the support frame. During installation, the mounting plate can be quickly assembled by matching the second positioning block with the second positioning groove, avoiding the need to confirm the assembly position and repeatedly align it. This further improves the efficiency of component assembly.

[0013] Preferably, the support frame has several mounting screw holes, and the PCB board is inserted with fixing bolts, which are threaded into the mounting screw holes. The support frame securely fixes the PCB board in place with the fixing bolts, preventing the PCB board from shaking in the mounting slot and causing the circuitry to fall off. This ensures the stability of the component assembly.

[0014] Preferably, the mounting slot is provided with several heat dissipation cavities and connecting holes. The heat dissipation cavities are recessed structures on the bottom of one side of the mounting slot, and the connecting holes connect the mounting slot and the surface slot. By providing several heat dissipation cavities and connecting holes, the weight of the support frame is reduced and airflow is improved. This achieves the effect of facilitating heat dissipation and reducing the counterweight of the support frame.

[0015] The beneficial effects of this utility model are: the touch structure enables multi-directional three-dimensional touch interaction and improves operability; it enhances interaction efficiency and user experience; it facilitates quick assembly between components; the structure has good heat dissipation and extends service life; it ensures the stability of component assembly; and it reduces the weight of the touch structure.
