Description

Technical Field

[0001] This utility model relates to the field of switch structure technology, specifically to switch structures and electrical equipment. Background Art

[0002] Existing mechanical electric heaters and other electrical appliances use toggle switches to adjust temperature settings. However, these switches lack clear feedback when adjusting settings, making it difficult for users to intuitively determine the current temperature setting. Furthermore, the lack of precise temperature limits can lead to inconsistent settings or inaccurate positioning, affecting user experience and device performance. Utility Model Content

[0003] In view of this, the present invention provides a switch structure and electrical device to solve the problems of the lack of clear gear feedback in the switch structure and the easy occurrence of gear jumps or inaccurate positioning.

[0004] In a first aspect, this utility model provides a switch structure, comprising:

[0005] Fixed bracket;

[0006] A switch is fixedly connected to the fixed bracket, and a gear adjustment part is slidably provided on the switch;

[0007] The operating component is slidably connected to the fixed bracket and connected to the gear adjustment part;

At least one protrusion is provided on the side wall of the first sliding bar, and the protrusion is used to limit and cooperate with different limiting grooves.

[0009] Beneficial effects: Users can apply force to the operating component, which in turn moves the gear adjustment unit. As the gear adjustment unit moves, the gear position of the electrical device can be adjusted via a switch. During the movement of the operating component, when the protrusion engages with different limiting grooves, the slight elasticity and friction generated as the protrusion switches between grooves enhance the user's tactile feedback, providing clear gear position feedback and improving the user experience. Simultaneously, the limiting grooves also limit the protrusion, ensuring precise gear positioning and preventing gear jumps or inaccurate positioning, thus guaranteeing user experience and equipment performance.

[0010] In one optional embodiment, at least three limiting protrusions protrude from the wall of the first sliding groove, and the at least three limiting protrusions are spaced apart along the sliding direction and form at least two limiting grooves with the wall of the first sliding groove.

[0011] Beneficial effects: The limiting groove is formed by the limiting protrusion and the groove wall of the first sliding groove. The elasticity of the limiting protrusion and the elasticity of the protrusion can be combined to increase the elasticity and reduce friction, further improving the user's sliding feel and providing clear gear feedback, thus enhancing the user experience. At the same time, the limiting protrusion and the protrusion are not easily damaged. It can also further improve the limiting effect of the limiting groove on the protrusion, achieving more precise gear positioning.

[0012] In one optional embodiment, at least two protrusions are provided on the sidewall of the first sliding bar, and the at least two protrusions are spaced apart along the sliding direction.

[0013] Beneficial effects: At least two protrusions can form a mating groove with the side wall of the first sliding strip, so that the mating groove can also limit the limiting protrusion, further improving the limiting accuracy of the gear and avoiding problems such as gear jump or inaccurate positioning.

[0014] In one optional embodiment, one end of the limiting protrusion is fixedly connected to the groove wall of the first sliding groove as a connecting end, and the other end is a free end. The free end is provided with a first guide surface on both sides of the sliding direction; in the direction away from the connecting end, the distance between the two first guide surfaces of the free end gradually decreases.

[0015] Beneficial effects: The setting of the first guide surface can guide the relative sliding between the protrusion and the limiting protrusion, reducing sliding resistance while ensuring a good limiting effect.

[0016] In one optional embodiment, the end of the protrusion away from the first sliding bar is provided with a second guide surface on both sides of the sliding direction, and the distance between the two second guide surfaces of the protrusion gradually decreases in the direction away from the first sliding bar.

[0017] Beneficial effects: The second guide surface can guide the relative sliding between the protrusion and the limiting protrusion, reducing sliding resistance while ensuring a good limiting effect.

The second sliding bar is slidably disposed in the second sliding groove, and the sliding direction of the first sliding bar is consistent with the sliding direction of the second sliding bar.

[0020] Beneficial effects: The sliding cooperation of the second sliding bar and the second sliding groove can further limit and guide the sliding of the operating component, ensuring smooth sliding.

[0021] In one optional embodiment, both the first sliding groove and the second sliding groove are disposed on the operating component and are respectively disposed at both ends of the operating component along the sliding direction of the first sliding bar.

[0022] Beneficial effects: The first sliding groove and the second sliding groove are respectively set at both ends of the operating component along the sliding direction, which can limit each other in the sliding direction, preventing the first sliding bar and the first sliding groove from separating, and also preventing the second sliding bar and the second sliding groove from separating.

[0023] In one optional embodiment, the fixed bracket includes a support plate with clearance holes, which are strip-shaped holes extending along the sliding direction of the first sliding bar; the switch and the operating component are respectively disposed on both sides of the support plate along a first direction; the gear adjustment part slides through the clearance holes and is connected to the operating component; the first direction is a direction perpendicular to the support plate.

[0024] Beneficial effects: The operating component and the switch are respectively positioned on both sides of the support plate along the first direction, separating them and protecting the switch from slippage damage.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0053] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0054] According to an embodiment of the present invention, a switch structure is provided, including a fixed bracket 1, a switch element 2, and an operating component 3; the switch element 2 is fixedly connected to the fixed bracket 1; the switch element 2 is slidably provided with a gear adjustment part 21; the operating component 3 is slidably connected to the fixed bracket 1 and connected to the gear adjustment part 21; wherein, either the fixed bracket 1 or the operating component 3 is provided with a first sliding groove 31, and the other is provided with a first sliding strip 11, the first sliding strip 11 being slidably disposed in the first sliding groove 31; at least two limiting grooves 311 are sequentially provided on the groove wall of the first sliding groove 31 along the sliding direction; at least one protrusion 111 is provided on the side wall of the first sliding strip 11, the protrusion 111 being used for limiting cooperation with different limiting grooves 311.

[0055] The user can apply force to the operating component 3, which will move the gear adjustment part 21. When the gear adjustment part 21 moves, the gear of the electrical device to be adjusted can be adjusted through the switch 2. During the movement of the operating component 3, when the protrusion 111 engages with different limiting grooves 311, the slight elasticity and friction generated when the protrusion 111 switches between different limiting grooves 311 will increase the user's sliding feel, provide clear gear feedback, and improve the user experience. At the same time, the limiting grooves 311 can also limit the protrusion 111 to achieve precise gear positioning, avoid gear jumps or inaccurate positioning, and ensure the user experience and equipment performance.

[0056] In a specific embodiment, the switch 2 is used to electrically connect to the structure to be adjusted in the electrical equipment. In this embodiment, the structure to be adjusted can be the heating structure 5; or, in other embodiments, the structure to be adjusted can be a motor that controls the rotation of the fan. When the gear adjustment part 21 slides relative to the switch 2, the gear of the structure to be adjusted can be adjusted by the switch 2. By applying force through the operating component, the gear adjustment part 21 can be moved to adjust between the power on, first gear, second gear, or other gears.

[0057] In one specific embodiment, the fixed bracket 1 is provided with a first sliding bar 11, and the operating component 3 is provided with a first sliding groove 31. In another specific embodiment, the fixed bracket 1 is provided with a first sliding groove 31, and the operating component 3 is provided with a first sliding bar 11.

[0058] In one specific embodiment, a limiting groove 311 is provided on one wall of the first sliding groove 31, and a protrusion 111 is provided on one side wall of the first sliding bar 11. In another specific embodiment, limiting grooves 311 are provided on both opposite walls of the first sliding groove 31, and the limiting grooves 311 on the two walls are arranged opposite to each other. Protrusions 111 are provided on both opposite side walls of the first sliding bar 11. In yet another specific embodiment, limiting grooves 311 are provided on both opposite walls of the first sliding groove 31, and the limiting grooves 311 on the two walls are staggered along the sliding direction. Protrusions 111 are provided on both opposite side walls of the first sliding bar 11, and the two protrusions 111 are arranged opposite to each other. When the protrusions 111 on different sides cooperate with different limiting grooves 311, they can represent a gear position.

[0059] In a specific embodiment, the first sliding groove 31 has two, three, four, five or more limiting grooves 311 arranged sequentially along the sliding direction on the groove wall. The number of limiting grooves 311 is consistent with the number of adjustable gears of the electrical device. The number of limiting grooves 311 on the first sliding groove 31 is the same as the number of adjustable gears of the electrical device. The number of limiting grooves 311 on the first sliding groove 31 is the same as the number of adjustable gears of the electrical device.

[0060] In one embodiment, at least two limiting grooves 311 are sequentially provided on the two opposite groove walls of the first sliding groove 31 along the sliding direction, and the limiting grooves 311 on the two groove walls are arranged opposite to each other; at least one protrusion 111 is provided on the two opposite side walls of the first sliding bar 11.

[0061] In a control panel and home appliance of related technology, the control panel includes a first panel and a switch 2. The side wall of the first panel has a first limiting part 132 with multiple first limiting grooves. The switch 2 includes a sliding plate that slides along the first panel. Each end of the sliding plate has a first positioning part, which is positioned between the multiple first limiting grooves 311 of the first limiting part 132. Since the first positioning parts at both ends protrude in opposite directions, when the sliding plate is controlled to slide, the first positioning parts at both ends experience opposite forces during the transfer process, causing the sliding plate to be subjected to a torsional force. This results in greater resistance to sliding and makes the switch 2 more susceptible to damage. In this embodiment, since the first sliding bar 11 is slidably disposed in the first sliding groove 31, when one side wall of the first sliding groove 31 is provided with a limiting groove 311, the corresponding side of the first sliding bar 11 is provided with a protrusion 111, and the other side wall of the first sliding groove 31 slides in cooperation with the other side of the first sliding bar 11; when both sides of the first sliding groove 31 are provided with limiting grooves 311, both sides of the first sliding bar 11 are also provided with protrusions 111; the first sliding groove 31 can limit both sides of the first sliding bar 11, and the opposing forces applied to the first sliding bar 11 can be partially offset, resulting in less resistance to the movement of the overall operating component 3, and it is not easy to damage the switch component 2.

[0063] The limiting groove 311 is formed by the limiting protrusion 312 and the groove wall of the first sliding groove 31. The elasticity of the limiting protrusion 312 and the elasticity of the protrusion 111 can be combined to increase the elasticity and reduce friction, thereby improving the user's sliding feel and providing clear gear feedback. This enhances the user experience. At the same time, the limiting protrusion 312 and the protrusion 111 are not easily damaged. The limiting effect of the limiting groove 311 on the protrusion 111 can also be further improved, achieving more precise gear positioning.

[0064] In a specific embodiment, every two adjacent limiting protrusions 312 can form a limiting groove 311 with the groove wall of the first sliding groove 31, and the groove wall perpendicular to the sliding direction can also form a limiting groove 311 with the limiting protrusion 312 near it.

[0065] In one embodiment, at least two protrusions 111 are provided on the sidewall of the first sliding bar 11, and the at least two protrusions 111 are distributed at intervals along the sliding direction.

[0066] At least two protrusions 111 can form a mating groove with the side wall of the first sliding bar 11, so that the mating groove can also limit the limiting protrusion 312, further improving the limiting accuracy of the gear position and avoiding problems such as gear shifting or inaccurate positioning.

[0067] In one embodiment, one end of the limiting protrusion 312 is fixedly connected to the groove wall of the first sliding groove 31 as a connecting end, and the other end is a free end. The free end is provided with a first guide surface 112 on both sides of the sliding direction. In the direction away from the connecting end, the distance between the two first guide surfaces 112 of the free end gradually decreases.

[0071] The second guide surface 313 can guide the relative sliding between the protrusion 111 and the limiting protrusion 312, reducing sliding resistance while ensuring a good limiting effect.

[0072] In a specific embodiment, the second guide surface 313 may be an inclined surface; or, the second guide surface 313 may also be an arc surface.
