Description

Technical Field

[0001] This utility model relates to the field of clothing and backpack technology for wearable electronic products, and particularly to a detachable switch for soft fabrics. Background Technology

[0002] In the current field of clothing and backpack technology, various electronic products are increasingly being integrated into clothing or backpacks, resulting in a variety of functional backpacks and garments, such as cooling backpacks, wind-cooled jackets, and luminous clothing. Various wearable garments, jackets, and backpacks incorporate a variety of functional electronic products.

[0003] However, this design leads to a problem: cleaning is difficult. Electronic products generally cannot be soaked in water, otherwise malfunctions may occur. Wearable devices, however, are inherently prone to getting dirty and require cleaning; otherwise, they lose their purpose in the long run. Therefore, existing wearable devices design core electronic components, such as rechargeable batteries and circuit board control components, as detachable structures, placing them in the wearable device's pocket and securing them using simple methods (direct placement, binding, buttons, etc.) so that they can be removed for cleaning without damaging the core electronic components.

[0004] However, it's difficult to implement a detachable structure for electronic components like power switches in current designs due to their specific requirements. 1. They need to be easily controlled and pressed by hand. While other components can be placed in pockets or other locations, and core electronic components are not frequently used or touched, their placement doesn't affect functionality. However, control switches require frequent use and touch. 2. Other core electronic components can be placed arbitrarily as needed. Power switches, however, must consider user convenience. For example, backpacks typically place them on the shoulder strap or below the body on the side of the backpack, while clothing usually places them on the chest or front hem. All these design solutions consider user convenience for touch and pressing. For instance, in existing technology CN212546066U, the push-button switch is designed on the shoulder strap. Existing technology CN219845474U places it on the side of the backpack closest to the body.

[0005] Based on the two design requirements mentioned above, it's generally difficult to design a detachable power switch due to its unique location, strict fixing requirements, and the need for stability and reliability. Therefore, in current technology, the power switch is typically fixed to the wearable device by stitching or adhesive, and then detachably connected to the core electronic components via conductive connectors (DC or USB plugs). Because power switches are relatively simple with few components (mainly a push-button switch and circuit board for switching current on and off), even occasional contact with water won't render them unusable. This is the common design approach for current electronic wearable devices.

[0006] However, this stitching and gluing inevitably leads to the power switch coming into contact with water, and repair and replacement remain difficult to resolve. Summary of the Invention

[0007] The purpose of this invention is to address the deficiencies in the prior art and provide a new switch that enables simple installation and disassembly, making it convenient for users. Furthermore, its design allows for basic waterproofing, thereby improving product reliability.

[0008] The objective of this utility model is achieved through the following means: A detachable switch for soft fabric includes a resilient keycap, a switch assembly, an upper housing, and a lower housing. The switch assembly is disposed between the upper and lower housings. The lower end of the resilient keycap is disposed inside the upper and lower housings, and the upper end of the resilient keycap is exposed outside the upper housing. The resilient keycap and the outer surface of the upper housing form an annular groove. The annular groove is engaged with an eyelet to allow the switch to be detachably fixed to a backpack.

[0009] In the above description, as a preferred embodiment, the elastic keycap is a one-piece molded structure, including a top key head for deformation under force, and a deformation cavity is formed on the inner side of the key head for generating deformation.

[0010] In the above description, as a preferred embodiment, an extension column extending downward is provided on the top side inside the deformation cavity. The extension column is a solid structure used to withstand downward force and trigger the switching assembly.

[0011] In the above description, as a preferred embodiment, the lower end of the elastic keycap has a planar structure that extends outwards to form an extended edge. This extended edge is engaged by the upper housing to prevent the elastic keycap from detaching from the upper housing uncontrollably, while simultaneously forming a sealing structure between the elastic keycap and the upper housing.

[0012] In the above description, as a preferred embodiment, a locking post structure is provided in the middle of the elastic keycap, the locking post and the upper housing are locked together, and an outwardly extending ring edge is provided at the top of the key head, the ring edge and the locking post forming an annular groove.

[0013] In the above description, as a preferred embodiment, the upper housing includes a keycap hole, a post hole, and a wire groove. The keycap hole is a through hole structure located on the upper surface of the upper housing for the elastic keycap to pass through. The post hole is located inside the upper housing and extends downward for mating with the lower housing. The wire groove is located on the side wall of the upper housing and has a semi-circular structure.

[0014] In the above description, as a preferred embodiment, the lower housing includes a positioning post, a support block, and a pressing edge. The positioning post is located inside the lower housing and extends upward to cooperate with the upper housing to connect the two. The support block is located inside the lower housing and extends upward to support the switch assembly and form pressure to create a sealing effect. The pressing edge is located at the opening of the lower housing and is used to fasten with the upper housing. A semi-circular wire groove is also provided on the side of the lower housing.

[0015] In the above description, as a preferred embodiment, the switch assembly includes a circuit board assembly and a push-button switch, with the push-button switch positioned above the circuit board assembly, and a corresponding guide hole provided on the circuit board assembly.

[0016] The beneficial effects of this utility model are: through the design and cooperation of the annular groove and deformation cavity on the elastic keycap and the eyelet buckle, it achieves the purpose of easy disassembly and installation, while achieving good key function, and through the combination of soft and hard, it achieves a basic waterproof function.

Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] This design addresses the shortcomings of existing technologies, which are inadequate in securing power switches, making them non-removable and inconvenient for maintenance and replacement. Based on practical considerations, the applicant has adopted a design using eyelet clips at designated locations on soft fabric. This design, combined with the existing technology, allows for simple installation and removal, facilitating easy disassembly and replacement.

[0020] For easy-to-remove switches used on soft fabrics, see reference. Figure 1 2. It includes four main components: a spring-loaded keycap 1 made of elastic material, a switch assembly 4, an upper housing 2, and a lower housing 3. The switch assembly 4 is located inside the housing formed by the upper housing 2 and the lower housing 3. The lower end of the spring-loaded keycap 1 is located inside the housing and above the switch assembly 4, and is used to press and trigger the switch assembly 4 to turn on the power.

[0021] refer to Figure 2 3, 4, The elastic keycap 1 is integrally injection molded from an elastic material, such as rubber or silicone. It includes the following parts: a raised circular key head 101 at the top; a locking post 103 extending downward from the key head 101; a ring edge 107 extending outward from the edge of the key head 1; and an extended edge 106 forming a square structure at the bottom of the elastic keycap 1. The size and shape of the extended edge 106 correspond to the shape and size of the inner cavity of the upper shell 2.

[0022] This structural feature creates an annular groove between the upper engaging post 103 of the elastic keycap 1 and the upper surface of the upper housing 2, where the eyelet 6 fits precisely into this groove. This achieves good stability and provides a certain degree of sealing, preventing rainwater from entering the switch.

[0023] Four guide holes 104 are provided at the four corners of the extension edge 106 to facilitate mutual fixing and engagement with the housing. A deformation cavity 102 is provided below the inside of the button head 101. A downward-extending extension post 105 is provided at the top of the deformation cavity 102. The extension post 105 is a solid structure and can provide a certain degree of support. (Reference) Figure 7 8. When the button head 101 is pressed by hand, due to the presence of the deformation cavity 102, the button head 101 can be recessed inward, causing the internal extension post 105 to move downward, thereby pressing the button switch 402 and achieving the control purpose of the circuit.

[0024] refer to Figure 5 The upper housing 2 is also a component made of plastic material by injection molding, including a keycap hole 201 and a post hole 202. The keycap hole 201 is used for the locking post 103 to pass through, and the post hole 202 is used to insert into the positioning post 301 on the lower housing 3 to achieve a snap-fit ​​connection between the two.

[0025] refer to Figure 6 8. The lower housing 3 is a one-piece injection-molded plastic component, including a positioning post 301, a support block 302, and a pressing edge 303. The positioning post 301 and the post hole 202 correspond to each other, and the upper and lower housings can be tightly fitted and fixed by a tight fit. At the same time, guide holes 104 are correspondingly opened on the extension edge 106 and the circuit board 401 to facilitate the passage of the positioning post 301 and the post hole 202. The support block 302 is located at the inner edge of the lower housing 3 to support the circuit board 401 and also to press it in place. The pressing edge 303 is located on the inner side of the top edge of the lower housing 3, protruding upwards, to cooperate with the upper housing 2 to form a stepped locking structure. This structure also facilitates waterproofing, delaying the penetration of water in the event of a small amount of rain.

[0026] refer to Figure 7 Eyelet clips 6 are installed on the soft fabric 7 of a backpack or clothing at a designated location, forming a circular through-hole structure with a metal edge, ensuring stability and reliability. This design achieves easy disassembly through the cooperation of the eyelet clips 6 and the switch; the button head 101 can be deformed by squeezing, allowing the eyelet clips 6 to be inserted and removed. Simultaneously, the eyelet clips 6 and the locking post 103 achieve an elastic fit, providing waterproofing. The circuit board 401 also creates a pressure seal on the extended edge 106. Furthermore, the power input and output wires engage with the wire groove 203 to achieve power signal input and output. One end of the wire is soldered to the circuit board 401, and the other end is connected to the corresponding electronic control equipment and power supply, realizing the switching function.

[0027] This design features a simple structure, making it very easy to disassemble and install, facilitating the cleaning of the wearable device, and also enabling easy maintenance and replacement of parts. Furthermore, this design achieves basic rainproof functionality through a combination of rigid and flexible materials.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
