Description

Technical Field

[0001] This utility model relates to the field of bedding, specifically to a control mechanism and a mattress. Background Technology

[0002] Existing mattresses include a mattress body with internal air chambers and a control mechanism that works in conjunction with the mattress body. The control mechanism includes a control box and electrical components mounted on the mattress body. The control box connects to the electrical components to perform corresponding functions and can also adjust the air pressure inside the air chambers to make the mattress firmness adjustable. The control box contains a circuit board, which is connected to the electrical components via wires. One end of the wire is connected to the circuit board via an interface, and the other end extends outward and connects to the electrical components. Because the wires bridge the control box and the electrical components, and the mattress body deforms under stress, the wires can be pulled and their ends can detach from the circuit board or electrical components, causing the electrical components to malfunction and affecting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a reliable control mechanism and mattress. A wire harness sleeve is installed on the wire, the length of which matches the wire and is fixed to the electrical components and the control box respectively. The wire harness sleeve transmits the pulling force to the control box, effectively preventing the wire from detaching from the circuit board due to being pulled, ensuring the reliability of the wire connection and improving the user experience.

[0004] This utility model achieves its purpose through the following method: a reliable control mechanism includes a control box and an electrical component external to the control box. The control box and the electrical component are connected by a wire. The wire is covered with a wire harness sleeve, and both ends of the wire harness sleeve are fixedly connected to the electrical component and the control box respectively, maintaining a constant length to prevent the wire from being pulled off. By providing a wire harness sleeve on the wire, matching the length of the wire and being fixedly connected to both the electrical component and the control box, the wire harness sleeve can withstand external pulling forces and transmit these forces to the control box. This prevents the wire from detaching from the circuit board due to direct force, ensuring the reliability of the wire connection and the operation of the electrical component, thus improving the user experience.

[0005] Preferably, the control box includes a base with a receiving groove and a cover plate that fits onto the base. The top edge of the base has a wire-passing groove, and the inner side of the bottom edge of the wire-passing groove has a wire-pressing plate. The wire-pressing plate is fixed to the inner wall of the base and clamps the wire harness sleeve, so that the corresponding ends of the base and the wire harness sleeve are fixedly connected. The cover plate fits onto the base and covers the opening of the receiving groove, so that the cover plate and the base together form a receiving cavity for the circuit board, which not only protects the circuit board but also facilitates disassembly and maintenance. The wire-passing groove allows wires and wire harness sleeves to pass through, and the wire-pressing plate is fixed to the side wall of the receiving groove and clamps the wire harness sleeve, ensuring that the wire harness sleeve is fixedly connected to the control box, effectively counteracting the pulling force on the wires, and ensuring that the wire laying distance remains constant.

[0006] Preferably, the pressure plate is U-shaped, including a plate body and support portions at both ends of the plate body. The pressure plate is fixed to the inner wall of the base through the support portions, forming a wire passage opening for the wire to pass through. The two sides of the wire harness sleeve port are clamped and fixed between the support portions and the inner wall of the base, so that the wire end separates from the wire harness sleeve after passing through the wire passage opening and connects to the circuit board disposed in the receiving groove. The support portions are attached to the side wall of the receiving groove and fixed by fasteners, so that the two sides of the wire harness sleeve end are clamped and fixed by the corresponding support portions and the side wall of the receiving groove, preventing the wire harness sleeve from detaching from the control box. The wire passage opening is formed between the support portions, and the wire is exposed at the end of the wire harness sleeve and connects to the circuit board after passing through the wire passage opening. The end of the wire harness sleeve can be set in a preset direction under the limiting action of the pressure plate to ensure that the wire can pass through the wire passage opening and connect to the circuit board.

[0007] Preferably, the pressure plate has through mounting holes at both ends, and fasteners pass through the mounting holes and are screwed and locked to the inner wall of the base to ensure that the pressure plate and the base can clamp and fix the wire harness sleeve.

[0008] Preferably, the wire harness sleeve is flat, with the wire located in the middle of the sleeve, forming clamping areas on both sides of the sleeve. The middle of the sleeve allows the wire to pass through, while the sides are clamped and fixed by clamping plates and bases to prevent damage or breakage of the wire due to clamping.

[0009] Preferably, the bottom surface of the cover plate is provided with a positioning buckle that can be vertically embedded into the wire threading groove. The positioning buckle is embedded into the wire threading groove and acts as a retaining element for the wire harness sleeve, effectively reducing the range of motion of the wire harness sleeve within the wire threading groove, preventing the end edge of the wire harness sleeve from breaking free of its restraint, thereby improving connection reliability.

[0010] Preferably, the end edge of the wire harness sleeve that is fixed to the control box is provided with a positioning hole, and a fastener passes through the positioning hole and is screwed to the inner wall of the base. By passing through the positioning hole and screwing to the base, the tensile force on the wire harness sleeve is transmitted to the base through the fastener, ensuring a secure connection between the wire harness sleeve and the control box.

[0011] Preferably, the wire harness sleeve and the electrical component are fixedly connected by sewing to ensure a firm connection between the wire harness sleeve and the electrical component and to prevent the wires from detaching from the electrical component.

[0012] Preferably, the electrical component is a pressure pad, which effectively senses the user's physiological parameters, sleeping posture, and other information, providing a basis for decision-making for the subsequent implementation of functions by the control box.

[0013] Preferably, the electrical component is a heating pad, which is powered on and generates heat to regulate the temperature of the pad.

[0014] Preferably, the wire harness sleeve is a nylon cloth sleeve, which ensures that the wire harness sleeve has good tensile strength, effectively transmits tensile force, protects the wires, and also has softness, making it easy to bend and lay synchronously with the wires.

[0015] Preferably, the wire harness sleeve and the wire have the same length. The structural strength of the wire harness sleeve is used to resist external pulling forces, thereby ensuring that the laying length of the wire remains constant and preventing the wire from detaching from the circuit board at the end due to the increase in laying length.

[0016] A mattress includes a mattress body on which the control mechanism is provided. The mattress body is equipped with a control box and electrical components, enabling the mattress body to perform corresponding functions and thereby improving the user experience.

[0017] Preferably, the control box is housed within the pad, which not only protects the control box but also simplifies the structure and enhances aesthetics.

[0018] Preferably, the electrical components are laid on the top surface of the pad, thereby improving the user experience by reducing the distance between the electrical components and the user.

[0019] Preferably, the pad has a perimeter edging, the top surface of the pad is covered with a comfort layer, and the pad, comfort layer, and edging are enclosed by an outer cover. The edging provides shaping and support for the perimeter of the pad, while the outer cover completely encloses the pad, comfort layer, and edging, providing both shaping and easy removal and cleaning, thus enhancing the user experience.

[0020] The beneficial effects of this utility model are as follows: A wire harness sleeve is set on the wire, the wire harness sleeve is matched with the length of the wire and is fixed to the electrical components and the control box respectively. The wire harness sleeve is used to withstand the external pulling force and transmit the pulling force to the control box, preventing the wire from detaching from the circuit board due to direct force, ensuring the reliability of the wire connection and the operation reliability of the electrical components, and improving the user experience.

[0028] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1:

[0030] This embodiment provides a control mechanism.

[0031] like Figure 1 , 2 The control mechanism shown in Figure 3 includes a control box 1 and an electrical component 2 externally mounted on the control box 1. The control box 1 and the electrical component 2 are connected by a wire 3. The wire 3 is covered with a wire harness sleeve 4. Both ends of the wire harness sleeve 4 are fixedly connected to the electrical component 2 and the control box 1 respectively, maintaining a constant length to prevent the wire 3 from being pulled off. The wire harness sleeve 4 is installed on the wire 3, matching the length of the wire 3 and being fixedly connected to both the electrical component 2 and the control box 1. The wire harness sleeve 4 bears the external pulling force and transmits the pulling force to the control box 1, preventing the wire 3 from detaching from the circuit board 12 due to direct force. This ensures the reliability of the wire 3 connection and the operational reliability of the electrical component 2, improving the user experience.

[0032] In this embodiment, the wire 3 is inserted into the wire harness sleeve 4. One end of the wire harness sleeve 4 is fixedly connected to the base 5, and the other end is fixedly connected to the electrical component 2. One end of the wire 3 is connected to the circuit board 12, and the other end is connected to the circuit inside the electrical component 2. When the wire 3 with the wire harness sleeve 4 is subjected to a pulling force due to the deformation of the pad 13, the pulling force will be transmitted to the control box 1 and the electrical component 2 through the wire harness sleeve 4 due to its good structural strength. This ensures that the length of the channel through which the wire 3 passes in the wire harness sleeve 4 remains unchanged, thereby ensuring that the relative position between the end of the wire 3 and the circuit board 12 in the control box 1 remains fixed, preventing the end of the wire 3 from detaching from the circuit board 12. When the pulling force is small, the control box 1 and electrical component 2 will use their own positioning structure to counteract the pulling force, ensuring that the wire 3 is laid along the original path; when the pulling force is large, the wire harness sleeve 4 will be subjected to force and deviate from the original laying path, and the control box 1 and electrical component 2 will use displacement to match the deformation of the wire harness sleeve 4, ensuring that the length of the wire harness sleeve 4 remains unchanged, thereby ensuring that the wire 3 will not detach from the circuit board 12 due to the increase in laying distance.

[0033] In this embodiment, one end of the wire harness sleeve 4 is fixedly connected to the control box 1 (e.g., Figure 5 (As shown). Specifically, the control box 1 includes a base 5 with a receiving groove and a cover plate 6 covering the base 5. The top edge of the base 5 is provided with a wire-passing groove 7, and the inner side of the bottom edge of the wire-passing groove 7 is provided with a wire-pressing plate 8. The wire-pressing plate 8 is fixed to the inner wall of the base 5 and clamps the wire harness sleeve 4 so that the corresponding ends of the base 5 and the wire harness sleeve 4 are fixedly connected. The end edge of the wire harness sleeve 4 that is fixed to the control box 1 is provided with a positioning hole 16. Fasteners pass through the positioning hole 16 and are screwed to the inner wall of the base 5. The end of the wire harness sleeve 4 passes through the wire-passing groove 7 and is fitted along the side wall of the receiving groove. The end of the wire harness sleeve 4 is fixed to the base 5 by fasteners passing through the positioning hole 16. The two sides of the end of the wire harness sleeve 4 are clamped and fixed by the wire-pressing plate 8 and the base 5 so that the port of the wire harness sleeve 4 is set downward, so that the wire 3 can extend downward and connect to the circuit board 12 after passing through the wire-passing port 11.

[0034] In this embodiment, the other end of the wire harness sleeve 4 is fixedly connected to the electrical component 2. Specifically, the wire harness sleeve 4 and the electrical component 2 are fixedly connected by sewing, and the wire 3 is connected to the internal circuit of the electrical component 2.

[0035] In this embodiment, the wire harness sleeve 4 and the wire 3 have the same length. After installation, the control box 1, the wire harness sleeve 4, and the electrical component 2 are firmly connected, forming a threading space for the wire 3, and the length of the threading space remains constant. When the wire 3 is subjected to a pulling force, the wire 3 can bend and deform without changing its length. The pulling force is transmitted to the control box 1 and the electrical component 2 through the wire harness sleeve 4, ensuring that the wire 3 will not detach from the circuit board 12.

[0036] In this embodiment, the pressure plate 8 is U-shaped (e.g., ...). Figure 4 As shown, the system includes a plate 9 and support portions 10 at both ends of the plate 9. The wire clamping plate 8 is fixedly attached to the inner wall of the base 5 through the support portions 10, forming a through-hole 11 for the wire 3 to pass through. The two sides of the wire harness sleeve 4 are clamped and fixed between the support portions 10 and the inner wall of the base 5, so that the end of the wire 3 passes through the through-hole 11, separates from the wire harness sleeve 4, and connects to the circuit board 12 disposed in the receiving groove. The wire clamping plate 8 clamps the clamping area of ​​the wire harness sleeve 4 through the cooperation of the support portions 10 and the side wall of the receiving groove, which not only improves the reliability of the fixed connection between the wire harness sleeve 4 and the base 5, but also limits the orientation of the end of the wire harness sleeve 4, preventing the wire 3 from being damaged due to excessive bending in some areas.

[0037] In this embodiment, the pressure plate 8 has through mounting holes at both ends. Fasteners pass through the mounting holes and are screwed and locked to the inner wall of the base 5. The inner wall of the base 5 has screw holes. Fasteners pass through the mounting holes and are screwed and locked to the corresponding screw holes. This ensures that the pressure plate 8 can cooperate with the base 5 to clamp the wire harness sleeve 4, and also allows for adjustment of the clamping force, making it convenient to adjust and use.

[0038] In this embodiment, the wire harness sleeve 4 is a flat nylon fabric sleeve, and the wire 3 is located in the middle of the wire harness sleeve 4 to form clamping areas on both sides of the wire harness sleeve 4. The flat shape of the wire harness sleeve 4 not only has good tensile strength, thus ensuring that its length remains constant, but also effectively reduces the feeling of foreign objects, and prevents the wire harness sleeve 4 from twisting and deforming, effectively extending its service life.

[0039] In this embodiment, the bottom surface of the cover plate 6 is provided with a positioning buckle 17 that can be vertically embedded in the wire threading groove 7. When the cover plate 6 is closed on the base 5, the positioning opening is embedded in the wire threading groove 7 and clamps the wire harness sleeve 4, which plays a positioning role on the end of the wire harness sleeve 4.

[0040] In this embodiment, the electrical component 2 is a pressure pad, heating pad, etc., used to achieve the corresponding function, and should all be considered as specific implementations of this embodiment. The wire 3 is connected between the electrical component 2 and the control box 1 to transmit electrical energy and signals, ensuring the controllable operation of the electrical component 2.

[0041] Example 2:

[0042] Compared to Embodiment 1, this embodiment provides a mattress.

[0043] like Figure 6The mattress shown includes a mattress body 13, on which the control mechanism is mounted. A control box 1 and electrical components 2 are installed on the mattress body 13, enabling it to perform corresponding functions and thus improving the user experience. When the mattress body 13 deforms due to force or in conjunction with the electric bed, the wiring harness sleeve 4 ensures a constant laying distance for the wires 3, thereby preventing the ends of the wires 3 from detaching from the circuit board 12 due to localized pulling force.

[0044] In this embodiment, the control box 1 is disposed inside the pad 13, which not only protects the control box 1, but also simplifies the structure and improves the aesthetics.

[0045] In this embodiment, the electrical component 2 is laid on the top surface of the pad 13, thereby improving the user experience by reducing the distance between the electrical component 2 and the user.

[0046] In this embodiment, the pad body 13 has a perimeter edge 14, and the top surface of the pad body 13 is covered with a comfort layer 15. The pad body 13, the comfort layer 15, and the perimeter edge 14 are wrapped by an outer cover. The perimeter edge 14 provides shaping and support for the perimeter of the pad body 13. The outer cover completely wraps around the pad body 13, the comfort layer 15, and the perimeter edge 14, which not only provides shaping but also facilitates disassembly and cleaning, thus improving the user experience.

[0047] The other structures and effects of the control mechanism described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
