Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a control device. Background Technology

[0002] With the development of smart home and IoT technologies, control devices such as wireless switches are widely used due to their advantages such as no wiring required and flexible installation. These control devices typically have built-in circuit modules to achieve signal triggering functions, generating control signals through physical pressing and operating without an external power supply.

[0003] In existing technologies, such control devices primarily rely on the structure of the circuit module itself to achieve the reset function. Specifically, the circuit module has contacts on its top for signal triggering and a spring block on its side to provide restoring force. The switch cover is directly pressed against the contacts and the spring block; when pressed, the contacts connect the circuit, and when released, the elasticity of the spring block pushes the cover back to its original position.

[0004] However, in actual use, it was found that the rebound force provided by the spring block is often insufficient, which makes the top cover reset action slow or even unable to fully rebound to the initial position, resulting in reset failure. This not only affects the user's operating feel, but also causes misjudgment of the switch trigger state. When the top cover is not fully reset, the contacts may remain in an abnormal contact state, causing the circuit to continue to conduct or the signal to be repeatedly sent. Utility Model Content

[0005] The purpose of this invention is to provide a control device to solve the technical problem of low reliability of the reset method in existing control devices.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A control device, comprising:

[0008] The top cover is equipped with a trigger.

[0009] The base cover is floatingly fastened to the upper cover, forming a first installation space between them. The first installation space is provided with an elastic reset structure and a control component.

[0010] The lower cover is rotatably fastened to the base cover, forming a second installation space between the two, and an elastic positioning structure is provided in the second installation space;

[0011] When a first force is applied to the upper cover, the upper cover moves toward the base cover, and the actuating element acts on the control component; when at least part of the first force is removed from the upper cover, the elastic reset structure pushes the upper cover away from the base cover; when the lower cover rotates relative to the base cover to the locked position, the elastic positioning structure locks the lower cover and the base cover together.

[0012] Preferably, the base cover is provided with a mounting groove, and the control component includes a circuit board and a micro switch. The circuit board is disposed in the mounting groove, and the micro switch is electrically connected to the circuit board. When a first force is applied to the top cover, the triggering element acts on the micro switch.

[0013] Preferably, the upper cover is provided with an anti-pressure component, which is opposite to the control component.

[0014] Preferably, the elastic reset structure includes an elastic arm and a connecting arm, the elastic arm extending at least partially beyond the surface of the base cover, and the connecting arm connecting the elastic arm and the surface of the base cover. When at least part of the first force is removed from the top cover, the elastic arm pushes the top cover away from the base cover.

[0015] Preferably, the elastic positioning structure includes an elastic positioning element and a positioning groove. The elastic positioning element extends outward from the surface of the lower cover and at least partially extends beyond the surface of the lower cover. The positioning groove is disposed on the surface of the base cover. When the lower cover rotates relative to the base cover to the locked position, the elastic positioning element is engaged and confined within the positioning groove.

[0016] Preferably, the upper cover surface is provided with a locking block, and the base cover surface is provided with a locking groove, and the locking block is engaged with the locking groove.

[0017] Preferably, the base cover has a protrusion on its surface and the lower cover has a locking groove. When the lower cover is rotated relative to the base cover to the locking position, the protrusion engages with the locking groove.

[0018] Preferably, the surface of the lower cover is provided with a fixing groove, and a magnetic suction element is provided in the fixing groove.

[0019] Preferably, the base cover is provided with a first through hole, and the lower cover is provided with a second through hole. When the lower cover is rotated relative to the base cover to the locked position, the first through hole and the second through hole are aligned.

[0020] Preferably, the lower cover is provided with an abutment member, which at least partially abuts against the control component when the lower cover is rotated relative to the base cover to the locked position.

[0021] The beneficial effects of this utility model are:

[0022] The control device proposed in this utility model forms a first installation space through the floating engagement of the upper cover and the base cover. This first installation space accommodates the elastic reset structure and the control components, allowing the elastic reset structure to act directly and effectively on the upper cover. When a first force is applied to the upper cover, it moves towards the base cover and triggers the control components. Subsequently, when at least part of the first force is removed, the elastic reset structure provides sufficient and reliable rebound force, ensuring that the upper cover quickly and stably partially or completely resets. This reduces the problems of delayed reset, failure, and false triggering caused by insufficient rebound force of the side spring blocks in existing technologies. Simultaneously, the base cover and the lower cover form a second installation space through rotational engagement. This second installation space can accommodate other electronic components and the elastic positioning structure. When the lower cover rotates relative to the base cover to the locked position, the elastic positioning structure automatically locks and fastens both, enhancing the overall installation stability and ease of assembly and disassembly of the device. Furthermore, the control device, through the cooperation of the upper cover, base cover, and lower cover, forms an independent first installation space and a second installation space, so that the structural components and electronic components inside each space can operate efficiently without physical interference and in function, thereby improving the space utilization rate of the control device.

[0038] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] See Figures 1 to 10 The control device provided in this embodiment of the utility model includes an upper cover 1, a base cover 2, and a lower cover 3. The upper cover 1 is provided with an actuating element 11; the base cover 2 is floatingly fastened to the upper cover 1, forming a first installation space between them, within which an elastic reset structure 21 and a control component 4 are provided; the lower cover 3 is rotatably fastened to the base cover 2, forming a second installation space between them, within which an elastic positioning structure 31 is provided; when a first force is applied to the upper cover 1, the upper cover 1 moves toward the base cover 2, and the actuating element 11 acts on the control component 4; when at least part of the first force is removed from the upper cover 1, the elastic reset structure 21 pushes the upper cover 1 away from the base cover 2; when the lower cover 3 rotates relative to the base cover 2 to a locked position, the elastic positioning structure 31 locks the lower cover 3 and the base cover 2 tightly together.

[0043] The control device forms a first mounting space through the floating engagement of the upper cover 1 and the base cover 2. This first mounting space accommodates the elastic reset structure 21 and the control component 4, allowing the elastic reset structure 21 to act directly and effectively on the upper cover 1. When a first force is applied to the upper cover 1, it moves towards the base cover 2 and triggers the control component 4. Subsequently, when at least part of the first force is removed, the elastic reset structure 21 provides sufficient and reliable rebound force, ensuring that the upper cover 1 quickly and stably partially or completely resets. This reduces the slow reset, failure, and false triggering problems caused by insufficient rebound force of the side spring blocks in existing technologies. Simultaneously, the base cover 2 and the lower cover 3 form a second mounting space through a rotating engagement. This second mounting space can accommodate other electronic components and the elastic positioning structure 31. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the elastic positioning structure 31 automatically locks both together, enhancing the overall installation stability and ease of assembly and disassembly of the device. Furthermore, the control device, through the cooperation of the upper cover 1, the base cover 2 and the lower cover 3, forms an independent first installation space and a second installation space, so that the structural components and electronic components inside each space can operate efficiently without physical interference and in function, thereby improving the space utilization of the control device.

[0044] The specific structure and working principle of the control device will be described in detail below.

[0045] The top cover 1 and the base cover 2 are installed by floating fastening. Either the base cover 2 is fastened to cover the top cover 1, or the top cover 1 is fastened to cover the base cover 2. Under different application scenarios or design requirements, the fastening method of the base cover 2 and the top cover 1 can be adaptively selected according to the actual situation to optimize the product's appearance, layout, and internal space utilization.

[0046] In this embodiment, the upper cover 1 has a receiving cavity 10, and the base cover 2 is at least partially disposed within the receiving cavity 10. By fastening the upper cover 1 to the outside of the base cover 2, the upper cover 1 directly faces the user's operating direction. The top surface and side walls fully covered by the upper cover 1 make the pressing operation area more ergonomic and improve the convenience of touch control. In addition, since the top surface of the upper cover 1 maintains a continuous and seamless flat appearance, it not only enhances the visual integrity of the control device and avoids the sense of fragmentation caused by assembly gaps on the operating surface, but also achieves a buffer function while taking into account aesthetics and practical protection. This keeps the connection seam between the base cover 2 and the upper cover 1 away from the user's operating area, making it difficult for dust, water, and other impurities to fall directly into it, effectively reducing the possibility of impurities entering the first installation space through the connection seam and causing damage to the control component 4.

[0047] To improve the stability of the installation of the upper cover 1 and the base cover 2, the surface of the upper cover 1 is provided with a locking block 13, and the surface of the base cover 2 is provided with a locking groove 23. The locking block 13 engages with the locking groove 23. Through the cooperation of the locking block 13 and the locking groove 23, a positioning mechanism is formed during the floating fastening installation process, so that when the upper cover 1 is fastened to the base cover 2, a clear assembly feedback is generated through the locking action, thereby improving production assembly efficiency and yield.

[0048] It is understandable that the locking block 13 can move along the movement direction of the upper cover 1 within the slot 23 and is limited by the inner wall at the end of the slot 23. Thus, when the control device is in operation, the locking action of the locking block 13 and the slot 23 limits the floating stroke of the upper cover 1 within the preset range of the slot 23, effectively preventing the upper cover 1 from accidentally dislodging under vibration or tilting conditions. At the same time, it maintains the parallel guiding relationship between the upper cover 1 and the inner wall of the base cover 2, ensuring that the upper cover 1 always moves smoothly in a direction perpendicular to the base cover 2 during the pressing operation.

[0049] In some embodiments, the base cover 2 may have a locking block 13 on its surface, and the top cover 1 may have a locking groove 23 on its surface. The locking block 13 engages with the locking groove 23 to achieve a floating limiting function. However, it should be noted that when the wall thickness of the top cover 1 is relatively thin, if the locking groove 23 is only opened in the inner wall of the accommodating cavity 10 without penetrating the top cover 1, its structural strength may not be able to meet the locking and fitting requirements. On the other hand, if a slotting method is adopted that penetrates the side wall of the accommodating cavity 10, although the locking block 13 can be inserted, it will cause the locking block 13 to be exposed on the surface of the top cover 1, which will not only destroy the overall integrity and aesthetics of the entire control device, but may also form a dust accumulation area. Therefore, the specific setting position of the locking groove 23 and the locking block 13 needs to be adaptively adjusted according to the actual wall thickness of the top cover 1, taking into account both structural strength and assembly reliability while ensuring the integrity of the appearance. The relevant implementation methods can be flexibly selected according to specific product requirements and are not limited here.

[0050] Preferably, a guide surface 131 is formed on the surface of the locking block 13. During installation, the guide surface 131 can guide the locking slot 23 to accurately align with the locking block 13, making the locking operation smoother, eliminating the need for repeated adjustments, and improving assembly efficiency. Moreover, the guide surface 131 can reduce any jamming or misalignment that may occur when the locking block 13 contacts the locking slot 23, ensuring that the locking block 13 can smoothly engage with the locking slot 23, and enhancing the tightness and accuracy of the connection between the base cover 2 and the top cover 1.

[0051] The guide surface 131 can be a guide slope, a guide arc surface, or a guide curved surface, etc. Its specific form is not limited here. It only needs to be able to guide the card block 13 to achieve the snap-fit ​​engagement with the card slot 23 during the assembly process of the base cover 2 and the top cover 1.

[0052] Furthermore, the surface of the accommodating cavity 10 is provided with a positioning post 14 extending toward the base cover 2, and the base cover 2 is provided with a positioning hole 26. When the base cover 2 and the upper cover 1 move relative to each other, the positioning post 14 is at least partially inserted into the positioning hole 26. During the assembly process of the upper cover 1 and the base cover 2, the cooperation between the positioning post 14 and the positioning hole 26 plays a precise positioning role, enabling the base cover 2 and the upper cover 1 to be assembled quickly and accurately, improving assembly efficiency and reducing assembly difficulty and the probability of error. In addition, the insertion of the positioning post 14 into the positioning hole 26 enhances the stability of the connection between the base cover 2 and the upper cover 1. In daily use of the equipment, it can better resist external impacts and vibrations, reduce the relative displacement of the housing caused by shaking, and ensure the stability of the control device structure. Moreover, when the upper cover 1 is pressed and moves, the positioning post 14 always maintains a sliding fit in the positioning hole 26, thereby guiding the upper cover 1 to move in the vertical direction and effectively suppressing the tendency of the upper cover 1 to tilt or twist.

[0053] After the upper cover 1 and the base cover 2 are installed, a first installation space is formed between them to accommodate components such as the elastic reset structure 21 and the control component 4. In use, by applying a first force to the upper cover 1 and pressing the upper cover 1, the upper cover 1 can move toward the base cover 2, thereby causing the trigger 11 to contact the control component 4 and trigger the control component 4.

[0054] Specifically, the base cover 2 is provided with a mounting groove 22. The control component 4 includes a circuit board 41 and a micro switch 42. The circuit board 41 is disposed in the mounting groove 22, and the micro switch 42 is electrically connected to the circuit board 41. When a first force is applied to the top cover 1, the actuating element 11 acts on the micro switch 42. The mounting groove 22 on the base cover 2 provides a stable positioning and installation position for the control component 4, allowing the circuit board 41 to be fixed in the mounting groove 22. At the same time, the micro switch 42 is integrated on the circuit board 41. When the top cover 1 is pressed, its actuating element 11 can directly and accurately act on the micro switch 42, ensuring the stability and accuracy of the trigger signal.

[0055] The micro switch 42 is located on the top of the circuit board 41 and faces the actuator 11. The layout of the micro switch 42 can be as follows: one micro switch 42 is placed at the center of the circuit board 41, and an actuator 11 is placed at the corresponding position on the upper cover 1; or multiple micro switches 42 are placed on the top of the circuit board 41 and arranged in a ring around the center of the circuit board 41, with an actuator 11 placed on the upper cover 1 at the position of each micro switch 42.

[0056] It is understandable that the number and arrangement of the microswitches 42 are not limited here, as long as it is ensured that when the upper cover 1 moves toward the base cover 2, the actuating element 11 can act on the microswitches 42, thereby triggering the circuit board 41.

[0057] In other embodiments, the control component 4 can also be a sensing sensor, such as a capacitive sensor, an infrared sensor, or an electromagnetic sensor. The trigger 11 and the control component 4 can be physically contacted to trigger the control component 4, or they can be triggered through non-physical contact methods, such as optical sensing or electromagnetic sensing, which will not be elaborated upon here.

[0058] Preferably, the control component 4 further includes a fixing member 43, which is used to fix the circuit board 41 to the mounting groove 22, thereby improving the stability of the circuit board 41 in the mounting groove 22 and preventing the circuit board 41 from being displaced or shaking in the mounting groove 22 due to external forces such as vibration and collision.

[0059] The fastener 43 can be made of screws, clips, or magnetic snaps, etc., and there is no limitation here.

[0060] Furthermore, the lower cover 3 is provided with an abutment 35. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the abutment 35 at least partially abuts against the control component 4. By abutting the control component 4 with the abutment 35, the position of the control component 4 in the mounting groove 22 can be further stabilized, preventing displacement due to vibration, shaking, etc. during use, thereby ensuring that the control component 4 can work stably and ensuring accurate transmission of control signals.

[0061] In this embodiment, the abutment 35 includes a first abutment 351 and a second abutment 352 spaced apart. The first abutment 351 is supported on the bottom edge of the control component 4, and the second abutment 352 is supported on the bottom center of the control component 4.

[0062] More specifically, the top cover 1 is provided with an anti-pressure member 12, which is opposite to the control component 4. When the top cover 1 is pressed, the anti-pressure member 12 can abut against the circuit board 41 after the trigger member 11 triggers the micro switch 42, thereby forming a physical limit and effectively preventing the top cover 1 from being pressed down too much and directly impacting the circuit board 41, thus avoiding deformation or damage to the circuit board 41 due to abnormal pressure.

[0063] Preferably, the outer periphery of the mounting groove 22 is provided with a groove edge 221 extending inward toward the upper cover 1, and the lower surface of the upper cover 1 is provided with a limiting ring 15 extending toward the base cover 2. When the base cover 2 and the upper cover 1 move relative to each other, the limiting ring 15 at least partially abuts against the groove edge 221. When the upper cover 1 is pressed and displaced relative to the base cover 2, the inner wall of the limiting ring 15 and the outer wall of the groove edge 221 maintain continuous sliding contact, guiding the upper cover 1 to move smoothly in a direction perpendicular to the base cover 2 through radial constraint, thereby avoiding radial displacement and deflection of the upper cover 1 and improving the stability of the upper cover 1 during movement. At the same time, the groove edge 221 can form an accommodating space, which plays a limiting and fixing role for the control component 4 installed in the mounting groove 22, making the position of the control component 4 in the mounting groove 22 more stable and preventing the control component 4 from shifting due to vibration and shaking during equipment use.

[0064] The base cover 2 has a first through hole 25, and the lower cover 3 has a second through hole 34. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the first through hole 25 and the second through hole 34 are aligned. An indicator light is provided on the circuit board 41. When the circuit board 41 is triggered and works normally, the indicator light emits a warning light. Thus, when the lower cover 3 rotates relative to the base cover 2 to the locked position, the indicator light, the first through hole 25, and the second through hole 34 are coaxially aligned. The first through hole 25 and the second through hole 34, together with the indicator light on the circuit board 41, form an optical channel that connects the inside and outside. When the circuit board 41 is triggered and works normally, the warning light emitted by the indicator light can pass through the first through hole 25 and the second through hole 34 in sequence and be projected to the outside, allowing the user to intuitively and clearly perceive the real-time operating status of the circuit board 41, improving the user's monitoring convenience, while maintaining the simplicity and reliability of the control device.

[0065] After the control component 4 is triggered, the elastic reset structure 21 can drive the upper cover 1 to reset, preparing for subsequent repeated triggering.

[0066] Specifically, the elastic reset structure 21 includes an elastic arm 211 and a connecting arm 212. The elastic arm 211 extends at least partially beyond the surface of the base cover 2, and the connecting arm 212 connects the elastic arm 211 and the surface of the base cover 2. When at least part of the first force is removed from the upper cover 1, the elastic arm 211 pushes the upper cover 1 away from the base cover 2. When the upper cover 1 applies pressure to the elastic reset structure 21, because the elastic arm 211 extends beyond the surface of the base cover 2, the extra extension allows the elastic arm 211 to have a larger elastic deformation space, thereby generating a larger elastic deformation. According to the principle of elastic potential energy, the greater the elastic deformation amplitude, the stronger the accumulated elastic potential energy. After the force on the upper cover 1 is removed, the strong elastic potential energy can more effectively restore the upper cover 1 to its original position, thereby effectively avoiding the situation where the upper cover 1 cannot be completely reset due to insufficient elastic potential energy. The connecting arm 212 strengthens the connection between the elastic arm 211 and the base cover 2, making the overall bond between the elastic arm 211 and the base cover 2 more secure. During long-term exposure to the pressure of the upper cover 1 and repeated elastic deformation, the elastic arm 211 is less likely to detach from the base cover 2, ensuring the stability and reliability of the electronic device structure. Furthermore, the connecting arm 212 can effectively distribute the stress borne by the elastic arm 211 during deformation, avoiding localized stress concentration and helping to maintain the elastic deformation capability of the elastic arm 211, thus extending the service life of the elastic reset structure 21.

[0067] More specifically, the elastic reset structure 21 also includes a support member 213 that extends outward from the surface of the upper cover 1. When a first force is applied to the upper cover 1, the support member 213 compresses the elastic arm 211.

[0068] In this embodiment, the support member 213 adopts a ring-shaped design that protrudes towards the elastic arm 211, ensuring that each elastic arm 211 can obtain uniform and directional compressive force transmission.

[0069] It should be noted that in other embodiments, the support member 213 can be adapted to an arc-shaped segment structure, a dispersed block structure, a columnar boss or an irregular geometric shape, etc. Its specific shape is not limited here, as long as it can ensure that the support member 213 always maintains effective contact with the corresponding elastic arm 211 and achieves controllable compression during the displacement of the upper cover 1.

[0070] Furthermore, the base cover 2 is provided with a receiving portion 27. When the support member 213 compresses the elastic arm 211, the receiving portion 27 at least partially accommodates the elastic arm 211. When the support member 213 compresses the elastic arm 211, the receiving portion 27 can accommodate the bent deformation portion of the elastic arm 211, avoiding interference and collision between the elastic arm 211 and the surrounding control components 4 or the housing structure, ensuring the free deformation capability of the elastic arm 211 under large compression, and allowing it to fully accumulate the elastic potential energy required for reset.

[0071] The base cover 2 and the lower cover 3 are rotated and fastened together, forming a second installation space between them. An elastic positioning structure 31 is provided in the second installation space.

[0072] Specifically, the elastic positioning structure 31 includes an elastic positioning member 311 and a positioning groove 312. The elastic positioning member 311 extends outward from the surface of the lower cover 3 and at least partially extends beyond the surface of the lower cover 3. The positioning groove 312 is provided on the surface of the base cover 2. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the elastic positioning member 311 is engaged and confined within the positioning groove 312.

[0073] When assembling the base cover 2 and the lower cover 3, the lower cover 3 is first initially aligned with the base cover 2, and then the lower cover 3 is rotated. During the rotation, the elastic positioning element 311 is compressed by the base cover 2, causing elastic deformation. When rotated to the locked position, the elastic positioning element 311 rebounds under the action of elastic potential energy and locks into the positioning groove 312, thereby locking the lower cover 3 and the base cover 2. At the same time, the sound emitted by the rebound can indicate to the user that the locking is complete. When disassembly is required, simply rotate the lower cover 3 in the opposite direction. The elastic positioning element 311 automatically undergoes elastic deformation under the compression of the base cover 2, causing it to disengage from the limit of the positioning groove 312 without interfering with the rotation process of the base cover 2. The entire process does not require manual pressing or moving of the elastic positioning element 311. The design of the elastic positioning element 311 automatically locking into the positioning groove 312 when rotated to the locked position achieves the function of quick locking and unlocking while ensuring the reliability of the connection. This makes the disassembly and assembly of electronic devices more efficient and labor-saving, effectively avoiding the tedious steps of repeatedly aligning the holes and reducing the difficulty of operation.

[0074] The elastic positioning member 311 includes a positioning arm 3111 and a mounting arm 3112. The positioning arm 3111 extends at least partially beyond the surface of the lower cover 3. The mounting arm 3112 connects the positioning arm 3111 and the surface of the lower cover 3. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the positioning arm 3111 engages and is confined within the positioning groove 312.

[0075] Furthermore, the lower cover 3 is provided with a mounting portion 39. When the lower cover 3 rotates relative to the base cover 2, the mounting portion 39 at least partially accommodates the positioning arm 3111. When the base cover 2 compresses the positioning arm 3111, the mounting portion 39 can accommodate the bent deformation portion of the positioning arm 3111, avoiding interference and collision between the positioning arm 3111 and the surrounding control components 4 or the housing structure, ensuring the free deformation capability of the positioning arm 3111 under large compression, and allowing it to fully accumulate the elastic potential energy required for reset.

[0076] In this embodiment, the base cover 2 is provided with a mounting cavity 20, and a positioning groove 312 is provided on the surface of the mounting cavity 20. The lower cover 3 is at least partially disposed within the mounting cavity 20. The mounting cavity 20 provides radial constraint for the rotational movement of the lower cover 3, ensuring that the two remain stably aligned during relative rotation and effectively preventing jamming failure caused by rotational offset.

[0077] To enable the rotation of the lower cover 3 relative to the base cover 2, an operating groove 301 is provided on the surface of the lower cover 3. Thus, when it is necessary to rotate the lower cover 3 to install or remove the base cover 2, the user's fingers or other operating parts can more easily grip or apply force to the operating groove 301, providing a point of leverage for operation and enhancing the convenience and comfort of operation.

[0078] The operating groove 301 can be an arc-shaped operating groove 301, the depth and contour of which are adapted to human fingers, allowing users to easily drive the rotation by inserting one or two fingers into the groove; or, the operating groove 301 can be a straight operating groove 301, allowing users to insert parts of any common flat or plate-shaped hard objects such as keys or coins into the straight operating groove 301 to drive the lower cover 3 to rotate.

[0079] Preferably, an indicator 302 is provided on the outer periphery of the operation slot 301. The indicator 302 is used to display the rotation path of the lower cover 3 about the locked position, thereby providing clear operation guidance for the user. When installing or removing electronic devices, the user can intuitively know how the lower cover 3 should be rotated, in which direction, and the specific path to the locked position based on the indicator 302, effectively avoiding misoperation caused by not knowing the operation path and improving the accuracy and efficiency of operation.

[0080] The indicator sign 302 can be a text sign, a graphic sign, or a symbol sign, etc. There is no limit to its specific form, as long as it can achieve the prompting effect.

[0081] When the lower cover 3 is rotated to the locked position, to improve the stability of the engagement between the base cover 2 and the lower cover 3, the surface of the base cover 2 is provided with a protrusion 24, and the lower cover 3 is provided with a locking groove 32. When the lower cover 3 rotates relative to the base cover 2 to the locked position, the protrusion 24 engages with the locking groove 32. Through the engagement of the protrusion 24 and the locking groove 32 at the locked position, a stable connection between the lower cover 3 and the base cover 2 is achieved, preventing the lower cover 3 and the base cover 2 from rotating relative to each other due to accidental force during the use of the electronic device, thus preventing the connection from becoming loose.

[0082] Specifically, the lower cover 3 is provided with a locking block 36, which extends outward from the surface of the lower cover 3, and a locking groove 32 is formed between the locking block 36 and the surface of the lower cover 3.

[0083] It is understandable that the extension direction of the locking groove 32 is parallel to the rotation direction of the lower cover 3, so as to ensure that the protrusion 24 can smoothly enter or disengage from the locking groove 32 during the rotation of the lower cover 3.

[0084] In this embodiment, a plurality of locking blocks 36 are arranged at intervals along the circumference of the lower cover 3, and a corresponding protrusion 24 is provided on the base cover 2 for each locking block 36.

[0085] Preferably, a guide surface 361 is formed on the surface of the locking block 36. During installation by rotating the lower cover 3 relative to the base cover 2, the guide surface 361 guides the protrusion 24 to slide smoothly into the locking groove 32, reducing alignment difficulty and making the installation operation smoother and more efficient. Simultaneously, the presence of the guide surface 361 also provides a buffering effect on the insertion of the protrusion 24, preventing damage from a hard collision between the protrusion 24 and the locking groove 32 due to improper force or positional deviation during installation, thus helping to improve the service life of the engagement structure between the protrusion 24 and the locking groove 32.

[0086] The guide surface 361 can be a guide slope, a guide arc surface, or a guide curved surface, etc. There is no specific limitation on its form. It is only necessary to ensure that the protrusion 24 can be smoothly engaged in the locking groove 32 during the rotation of the lower cover 3.

[0087] More specifically, the lower cover 3 is provided with a guide groove 37, which communicates with the locking groove 32. When the lower cover 3 rotates relative to the base cover 2, the guide groove 37 at least partially accommodates the protrusion 24. The guide groove 37 provides a guiding path for the protrusion 24 to enter the locking groove 32, allowing the protrusion 24 to slide into the locking groove 32 more accurately and smoothly, reducing alignment difficulty and improving installation efficiency. Simultaneously, during rotation, the guide groove 37 accommodating the protrusion 24 restricts its position, preventing it from shifting and ensuring the accuracy and reliability of the final engagement between the protrusion 24 and the locking groove 32.

[0088] Furthermore, in the lower cover 3 and the mounting cavity 20, one is provided with a limiting groove 38, which extends along the rotation path of the lower cover 3. The other is provided with a limiting block 28 corresponding to the limiting groove 38. The limiting block 28 is engaged and slidably connected within the limiting groove 38. When the lower cover 3 rotates, the limiting block 28 can move within the limiting groove 38. When the lower cover 3 rotates, the limiting block 28 moves within the limiting groove 38, ensuring that the lower cover 3 rotates along the predetermined rotation path and preventing the lower cover 3 from deviating or wobbling during rotation, effectively improving the stability and accuracy of rotation. At the same time, when the limiting block 28 moves to the end of the limiting groove 38, it forms a rigid stop, thereby preventing the lower cover 3 from being overloaded and damaged due to excessive rotation, thus further ensuring the reliability and durability of the electronic device.

[0089] One option is to set a limiting groove 38 on the lower cover 3 and a limiting block 28 in the mounting cavity 20; another option is to set a limiting block 28 on the lower cover 3 and a limiting groove 38 in the mounting cavity 20. There is no limitation here, as long as the limiting block 28 and the limiting groove 38 correspond one-to-one and cooperate with each other. The specific setting position can be adapted to the actual needs of the internal space of the electronic device.

[0090] In addition, the control component 4 also includes a battery 5. A battery slot 201 is provided on the base cover 2, and the battery 5 is disposed in the battery slot 201. The battery 5 is used to supply power to the circuit board 41.

[0091] Specifically, the inner wall of the battery compartment 201 is provided with an elastic buckle 202. The elastic buckle 202 includes a connecting part and a protrusion. The connecting part is elastically connected to the inner wall of the battery compartment 201, and the protrusion is located at the bottom of the battery 5.

[0092] In this embodiment, the first abutment 351 is supported on the bottom edge of the battery 5, and the second abutment 352 is supported on the bottom center of the battery 5. Together with the elastic buckle 202, the battery 5 can be stably fixed in the battery slot 201.

[0093] The lower cover 3 has a fixing groove 33 on its surface, and a magnetic attractor 6 is installed in the fixing groove 33. The magnetic attractor 6 can use magnetic force to attract other magnetic objects, which makes it easy for the control device to be firmly connected to the mounting surface of metal or other magnetic components, thus broadening the installation methods and application scenarios of the control device and improving the ease and flexibility of installation.
