Description

Technical Field

[0001] This utility model relates to a palm-sized device, and more particularly to a palm-sized device for improving concentration, belonging to the field of medical device technology. Background Technology

[0002] In today's social environment, distractibility has become a common cognitive impairment, significantly affecting learning efficiency, work quality, and mental health. For example, it can significantly reduce efficiency, increase error rates, and weaken creativity; affect learning outcomes and memory conversion, leading to difficulties in information retention; trigger psychological stress such as anxiety and frustration; and damage interpersonal relationships and reduce empathy.

[0003] In order to improve concentration, more and more people are using meditation and other concentration training to enhance awareness and inner peace. However, beginners are easily distracted and cannot maintain their attention for a long time to maintain the training state. In addition, existing concentration training aids also have significant shortcomings, as follows: (1) Smart bracelets / watches: only provide basic heart rate or motion monitoring, lacking specific algorithms and intervention logic for concentration; (2) Meditation apps: rely on visual / auditory interaction, which may increase cognitive load and cannot be effective in non-electronic device usage scenarios (such as paper reading); (3) Neurofeedback head-mounted devices: bulky, uncomfortable to wear, and require a fixed terminal to use, resulting in poor portability and user compliance.

[0004] Therefore, there is an urgent need for a portable, proactive, and low-intervention-threshold attention enhancement device that can instantly interrupt the chain of distractions and rebuild a state of focus through tactile and auditory feedback, thereby filling the technological gap in the field of portable attention enhancement tools and providing a breakthrough path for solving systemic cognitive impairment. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a palm-sized device for improving concentration, which aims to rebuild a state of focus through tactile and audio-visual feedback.

[0006] To achieve the above technical objectives, this utility model provides a palm-sized device for improving concentration, including an upper cover and a lower cover connected to each other, as well as a circuit board, a battery, a charging component, a button component, a light component, and a driving component;

[0007] The drive assembly includes a motor, a rotating mechanism, and a touch head. The battery, charging assembly, button assembly, lighting assembly, and motor are all electrically connected to the circuit board, and the start, stop, direction, and speed of the motor are controlled by the button assembly.

[0008] The lower cover has a base plate installed inside, which divides the interior of the lower cover into an upper receiving cavity and a lower rotating cavity; the circuit board, battery, charging component, button component, light component and motor are installed in the receiving cavity, with the battery located below the circuit board and the motor located below the battery; the rotating mechanism and touch head are installed in the rotating cavity;

[0009] The rotating mechanism includes a rotating arm; the base plate has a mounting through hole at its center; the motor shaft passes through the mounting through hole downwards and is adjustablely connected to the rotating arm; the touch head is installed at one end of the rotating arm; the rotating arm can adjust its rotation radius along its own length direction and can rotate around the motor shaft.

[0010] Furthermore, the rotating mechanism also includes a slider; the top surface of the rotating arm has a groove along its length, and the bottom surface of the groove has several equally spaced slots; the slider has two rectangular holes with spring pieces at both ends, and the bottom surface of the spring pieces has downward protruding engaging teeth; the slider is installed in the groove, and the motor shaft passes through the mounting hole downward and connects to the center of the slider, thereby connecting with the rotating arm; the rotating arm can move along the slider, and the two engaging teeth can engage in the corresponding slots, thereby adjusting the rotation radius of the rotating arm.

[0011] The working principle of the above technical solution is as follows: Place the device in the user's palm, with the bottom surface of the lower cover (where the rotating arm is located) facing the palm, and grip the device with all five fingers, ensuring the touch head is firmly against the palm. Since the motor is fixed within the lower cover, its rotation drives the rotating arm to rotate. The touch head at the end of the rotating arm contacts the user's hand and rotates within the palm, thereby enhancing personal focus by applying tactile and rotational force to the palm. When it is necessary to change the rotation radius to touch other parts of the palm, pull the rotating arm, causing the slide to move along the slider, thus adjusting the position of the rotating arm and the rotation radius.

[0012] Furthermore, the rotating mechanism also includes a plug and a rubber block; the rotating arm has several insertion holes evenly distributed along its length; the bottom end of the motor shaft is equipped with a plug and a rubber block connecting the plug; the rubber block can be inserted into different insertion holes, thereby adjusting the rotation radius of the rotating arm.

[0013] The working principle of the above technical solution is as follows: The bottom end of the motor shaft is connected to the rotating arm through a mounting hole, and is clamped and fixed by the deformation of the rubber block. When it is necessary to change the rotation radius of the rotating arm, the rotating arm is pulled out from the rubber block by external force, and then the end of the motor shaft is inserted into the corresponding hole according to the required radius length, so that the position of the rotating arm and the rotation radius can be adjusted.

[0014] Furthermore, the drive assembly also includes a spring, an extension rod, and a cylinder; the two ends of the spring are respectively connected to the inner sidewall of the rotating cavity and the rotating arm; the bottom end of the motor shaft is equipped with an extension rod, which extends downward through the mounting hole and connects to the rotating arm; the cylinder is installed in the receiving cavity and electrically connected to the circuit board, and its telescopic end extends through the bottom plate and connects to the rotating arm, thereby driving the rotating arm to move along the axial direction of the motor shaft.

[0015] The working principle of the above technical solution is as follows: When the cylinder extends, it drives the rotating arm to press down, which increases the downward pressure of the touch head on the user's palm; when the cylinder retracts, it drives the rotating arm to rise, which decreases the downward pressure of the touch head on the user's palm. In this way, the change in pressure makes the user's palm feel different, thereby enhancing the technical effect of improving concentration.

[0016] Furthermore, the touch head is two-ended, with one end made of a hard material and the other end made of a soft material; or, the touch head is spherical, with one half made of a hard material and the other half made of a soft material.

[0017] The working principle of the above technical solution is as follows: by changing the softness and hardness of the touch head at the end of the rotating arm, the technical effect of this utility model in improving concentration can be further enhanced.

[0018] Furthermore, the charging assembly includes a charging fixing groove formed on the outer wall of the receiving cavity, and two charging springs; the charging fixing groove has two charging ports symmetrically formed; the bottom of the charging spring has a horizontal U-shaped bend protruding to one side, and the top has an L-shaped bend protruding to the other side; and the two horizontal U-shaped bends are respectively inserted into the corresponding charging ports from the inside of the receiving cavity outwards, and the two L-shaped bends are respectively electrically connected to the circuit board.

[0019] The working principle of the above technical solution is as follows: This utility model can charge the battery through the charging port, thereby driving other components to work, and can also store electrical energy in the battery and be used as a power bank.

[0020] Furthermore, the charging assembly also includes a magnetic iron sheet installed in the charging fixing slot; the charging fixing slot also has two side positioning slots located on both sides of the two charging ports, and a lower positioning slot located below the two charging ports, and both the side positioning slots and the lower positioning slot are recessed into the receiving cavity; the magnetic iron sheet includes two reserved holes, two side through holes located on both sides of the reserved holes, and a lower through hole located below the reserved holes; the outer ends of the two charging ports pass through the corresponding reserved holes, the outer ends of the two side positioning slots pass through the corresponding side through holes, and the lower positioning slot passes through the lower through hole.

[0021] The working principle of the above technical solution is as follows: When the present invention is charging, the two side plugs and one bottom plug of the charger are respectively inserted into the two side positioning slots and the bottom positioning slot, and the magnetic iron sheet magnetically attracts the charger, thereby enhancing the stability of the charger.

[0022] Furthermore, the lighting assembly includes several low beam lamps and several warning lights mounted on the top surface of the circuit board; and the low beam lamps are turned on and off, and the flashing frequency and on / off status of the warning lights are controlled by a button assembly.

[0023] The working principle of the above technical solution is as follows: the flashing frequency and on / off state of the warning light, the on / off state of the low beam headlight, the start / stop, forward / reverse rotation, and speed control of the motor, as well as timer and countdown functions are controlled by the button component.

[0024] Furthermore, the button assembly includes several buttons located in the receiving cavity, several button slots formed on the side wall of the receiving cavity, several limiting protrusions mounted on the top surface of the base plate, several travel slots formed on the edge of the circuit board, and a switch installed in each travel slot. The positions of the travel slots and button slots are matched, and the number of buttons, switches, travel slots, and button slots are matched. The button includes a pressing part and a travel part. The top of each travel part is located in the corresponding travel slot, the bottom is located between the corresponding limiting protrusion and the inner side wall of the receiving cavity, and a contact is provided on the outer side. Each pressing part is inserted into the corresponding button slot and is located outside the corresponding contact.

[0025] The working principle of the above technical solution is as follows: When the pressing part is pressed, it squeezes the contact point of the corresponding travel part, and the travel part moves towards the travel groove, thereby contacting the switch and pressing the switch to realize the switching function. When the switch is released, the button part resets due to the properties of the rubber material.

[0026] Furthermore, the top cover is provided with several transparent rectangular frames and several lenses; the transparent rectangular frames are matched with the size and number of warning lights; the lenses are in the shape of upward-convex semicircles, and the size and number of lenses are matched with the low beam lights.

[0027] The working principle of the above technical solution is as follows: the transparent rectangular frame is to allow the warning light to radiate outwards without being obstructed by the top cover. The lens acts as a lampshade for the low beam headlight.

[0028] In summary, this utility model provides a portable, proactive, and low-intervention-threshold attention enhancement device, and has multiple technical effects:

[0029] Firstly, when this invention is held in the user's palm, the touch head can stimulate the palm to improve personal concentration. Especially when the user is lost in thought or distracted, the changes in stimulation of the palm by this invention can bring the mind back and thus enter a state of focused attention. The rotation radius of the rotating arm can be adjusted to touch different parts of the palm, so that the position of force on the palm changes. Furthermore, the technical effect of improving concentration can be further enhanced by the changes in the softness and hardness of the touch head at the end of the rotating arm and the changes in the pressure applied.

[0030] Secondly, one implementation of this utility model has the effects of both low beam and warning light, and can provide a light source in dark environments. It not only has low power consumption but also low energy consumption.

[0031] Thirdly, in one implementation of this utility model, the charging component can be used as a power bank, and it is easy to carry. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0051] In the description of this application, terms such as "connection" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Furthermore, terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] like Figures 1 to 3 As shown, this embodiment provides a palm-sized device for improving concentration, including an upper cover 1 and a lower cover 2 connected to each other, and a circuit board 3, a battery 4, a charging component, a button component, a light component and a driving component installed inside the lower cover 2, which are described in detail below.

[0053] Among them, such as Figure 2 , Figure 3 As shown, the drive assembly includes a motor 5, a rotating mechanism, and a touch head 7. The battery 4, charging assembly, button assembly, light assembly, and motor 5 are all electrically connected to the circuit board 3, and the start, stop, forward and reverse rotation, and speed of the motor 5 are controlled by the button assembly.

[0054] like Figures 2 to 4 As shown, the lower cover 2 is cylindrical, and a base plate 21 is installed inside it. The base plate 21 divides the interior of the lower cover 2 into an upper receiving cavity 22 and a lower rotating cavity 23. The circuit board 3, battery 4, charging component, button component, light component and motor 5 are installed in the receiving cavity 22, and the battery 4 is located below the circuit board 3 and the motor 5 is located below the battery 4. The rotating mechanism and touch head 7 are installed in the rotating cavity 23.

[0055] like Figure 2 , Figure 3 , Figure 5 , Figure 12 As shown, the rotating mechanism includes a rotating arm 6, and the base plate 21 has a mounting through hole 211 at its center; the motor 5 rotates downward through the mounting through hole 211 and is connected to the rotating arm 6; the touch head 7 is installed at one end of the rotating arm 6; the rotating arm 6 can adjust its rotation radius along its own length direction and can rotate around the rotating shaft of the motor 5.

[0056] In some embodiments, such as Figure 3 As shown, in order to adjust the position and rotation radius of the rotating arm 6, the rotating mechanism also includes a slider 8; as Figure 13 , Figure 14 As shown, the top surface of the rotating arm 6 has a groove 61 along its length, and the bottom surface of the groove 61 has a plurality of equally spaced slots 62. Figure 15As shown, the slider 8 has two rectangular holes 81 at both ends, and each rectangular hole 81 contains a spring piece 82, with downward-protruding engaging teeth on the bottom surface of the spring piece 82. Figure 13 As shown, the slider 8 is engaged in the slide groove 61, and the motor 5 rotates downward through the mounting through hole 211 and connects to the center of the slider 8, thereby connecting the rotating arm 6; the rotating arm 6 can move horizontally along the slider 8 through the slide groove 61, thereby changing the rotation radius of the rotating arm 6, and the engaging teeth of the two spring pieces 82 can be inserted into the corresponding slots 62, thereby locking the rotation radius of the rotating arm 6.

[0057] In practice, since the slider 8 is fixedly connected to the shaft of the motor 5, and the rotating arm 6 is connected to the slider 8 via the slide groove 61, the rotating arm 6 can slide along the slide groove 61. Furthermore, the spring piece 82 is made of plastic. When the rotation radius of the rotating arm 6 needs to be adjusted, pulling the rotating arm 6 causes the spring piece 82 to retract under external force, disengaging the two engaging teeth from their corresponding slots 62. This allows the rotating arm 6 to slide along the slider 8 via the slide groove 61, thereby changing the rotation center and rotation radius of the rotating arm 6. When the rotating arm 6 is pulled to the desired position, the two engaging teeth insert into the corresponding slots 62, thus fixing the rotation center and rotation radius of the rotating arm 6.

[0058] It should be noted that the key technical point of this utility model embodiment is that the rotation center of the rotating arm 6 is adjustable, thereby changing the rotation radius to achieve touching different positions of the palm. In addition to the above technical solution, other technical means can also be used to achieve the technical effect. In some other embodiments, the rotating mechanism also includes a plug and a rubber block; the rotating arm 6 is evenly provided with insertion holes along its length; the bottom end of the motor 5 shaft is equipped with a plug, the plug is connected to the rubber block, and the rubber block can be inserted into different insertion holes, thereby changing the rotation center and rotation radius of the rotating arm 6.

[0059] In practice, mounting holes are provided on the side of the rotating arm 6 near the motor 5, and these mounting holes are evenly spaced along the length of the rotating arm 6. A plug and a rubber block connecting the plug are provided at the end of the motor 5 shaft near the rotating arm 6. The motor 5 shaft is inserted into the rotating arm 6 through the mounting holes and clamped in place by the deformation of the rubber block. When the rotation radius needs to be changed, the rotating arm 6 is pulled off the rubber block by external force, and then the end of the motor 5 shaft is inserted into the corresponding mounting hole according to the required radius length.

[0060] In some embodiments, the effect of this invention in enhancing concentration can be further enhanced by applying changes in pressure. Specifically, the drive assembly also includes a spring, an extension rod, and a cylinder; one end of the spring is connected to the inner wall of the rotating cavity 23, and the other end is connected to the rotating arm 6; an extension rod is axially mounted on the shaft of the motor 5, and the extension rod passes downward through the mounting through hole 211 and connects to the rotating arm 6; the cylinder is installed in the receiving cavity 22 and electrically connected to the circuit board 3, and its telescopic end passes through the base plate 21 and connects to the rotating arm 6, thereby driving the rotating arm 6 to move up and down along the axial direction of the shaft of the motor 5.

[0061] In specific implementation, an extension rod is added to the bottom end of the motor 5 shaft; the rotating arm 6 is modified to be penetrated by the extension rod and can slide up and down along the extension rod; a spring is added between the rotating arm 6 and the lower cover 2 for reset; a limiting part is added to the end of the extension rod that penetrates the rotating arm 6 to prevent the rotating arm 6 from falling; and a cylinder is installed in the receiving cavity 22 of the lower cover 2. The telescopic end of the cylinder penetrates the base plate 21 and is fixedly connected to the rotating arm 6, thereby controlling the up and down movement of the rotating arm 6 by the telescopic movement of the cylinder, with the up and down movement path based on the extension rod. When the telescopic end of the cylinder extends, it drives the rotating arm 6 to press down, increasing the downward pressure of the touch head 7 on the user's palm; when the telescopic end of the cylinder retracts, it drives the rotating arm 6 to rise, decreasing the downward pressure of the touch head 7 on the user's palm. In this way, the change in pressure makes the user's palm feel different, thereby further enhancing the user's concentration.

[0062] In some embodiments, the varying hardness of the touch head 7 at the end of the rotating arm 6 can further enhance the technical effect of this invention in improving concentration. Specifically, the touch head 7 is two-ended, with one end made of a hard material and the other end made of a soft material; or, the touch head 7 is spherical, with one half made of a hard material and the other half made of a soft material.

[0063] In practical implementation, the touch head 7 is made into a two-ended shape, with one end being a hard head, such as plastic, and the other end being a soft head, such as soft rubber. These two ends are respectively located at both ends of the rotating arm 6 and can be threaded into the threaded holes 63 on the rotating arm 6. When it is necessary to change the hardness of the touch head 7, the touch head 7 can be disassembled and its direction changed. Alternatively, the touch head 7 can be made into a spherical shape, with a bearing embedded in the rotating arm 6 to connect to the spherical touch head 7. Half of the spherical touch head 7 is made of hard material, and the other half is made of soft material, thus changing the hardness of the touch by rotating the spherical surface.

[0064] In other embodiments, such as Figure 16As shown, the touch head 7 includes a touch end 71 and a connection end 72 connected to each other, and the connection end 72 is provided with an external thread; one end of the rotating arm 6 is provided with a threaded hole 63, and the connection end 72 of the touch head 7 is connected to the threaded hole 63 of the rotating arm 6 by a thread.

[0065] In some embodiments, such as Figure 4 , Figure 7 As shown, the charging assembly includes a charging fixing groove 24 formed on the outer wall of the receiving cavity 22, and two charging springs 25 installed in the charging fixing groove 24; the charging fixing groove 24 has two charging ports 241. Figure 6 , Figure 7 As shown, the bottom of the charging spring 25 is provided with a horizontal U-shaped bend 251 protruding to one side, and the top is provided with an L-shaped bend 252 protruding to the other side; and the horizontal U-shaped bends 251 of the two charging springs 25 are respectively inserted into the corresponding charging ports 241 from inside the receiving cavity 22 outwards, and the L-shaped bends 252 of the two charging springs 25 are respectively electrically connected to the circuit board 3.

[0066] In specific implementation, such as Figure 9 As shown, the circuit board 3 has two spring contact slots 31. The L-shaped bends 252 of the two charging spring contacts 25 are inserted into the corresponding spring contact slots 31 and connected to the circuit board 3 by soldering. This utility model can charge the battery 4 through the charging port 241 to drive other components to work, or store electrical energy in the battery 4 and use it as a power bank.

[0067] In other embodiments, such as Figure 3 As shown, the charging assembly also includes a magnetic attracting piece 26 installed within the charging fixing slot 24. (As shown...) Figure 4 , Figure 5 As shown, the charging fixing slot 24 also has two side positioning slots 242 located on both sides of the two charging ports 241, and a lower positioning slot 243 located below the two charging ports 241, and both the side positioning slots 242 and the lower positioning slot 243 are recessed into the receiving cavity 22. Figure 1 , Figure 8 As shown, the magnetic attracting iron piece 26 includes two reserved holes 261, two side through holes 262 located on both sides of the two reserved holes 261, and a lower through hole 263 located below the two reserved holes 261; and the outer ends of the two charging ports 241 pass through the corresponding reserved holes 261 and extend outward, the outer ends of the two side positioning grooves 242 pass through the corresponding side through holes 262 and extend outward, and the lower positioning groove 243 passes through the lower through hole 263 and extends outward.

[0068] In specific implementation, the magnetic iron plate 26 and the charging fixing groove 24 are fixedly connected by coating, and the two reserved holes 261, two side through holes 262 and one lower through hole 263 on the magnetic iron plate 26 are respectively matched with the two charging ports 241, two side positioning grooves 242 and one lower positioning groove 243 on the charging fixing groove 24, so as to facilitate the charger of this utility model to be inserted into the two side positioning grooves 242 and one lower positioning groove 243 for positioning and installation.

[0069] Specifically, the charger of this embodiment has two charging pins, two side plugs on either side of the pins, and a lower plug below them. The two side plugs match the two side positioning slots 242, and the lower plug matches the lower positioning slot 243. When charging, the two side plugs and the lower plug are inserted into the two side positioning slots 242 and the lower positioning slot 243 respectively, and the charger is magnetically attracted by the magnetic iron piece 26, thereby enhancing the stability of the charger.

[0070] In some embodiments, such as Figure 4 , Figure 5 As shown, a plurality of snap fasteners 221 and a plurality of reinforcing ribs 222 are installed on the inner wall of the receiving cavity 22; as Figure 10 As shown, the edge of the circuit board 3 is placed on several reinforcing ribs 222 and engaged in several buckles 221.

[0071] In specific implementation, such as Figure 10 , Figure 15 As shown, several clips 221 engage with the edge of the circuit board 3, limiting its position and fixing it to the battery 4. By limiting the circuit board 3, the battery 4 is pressed between the circuit board 3 and the motor 5, forming a clamping and fixing mechanism. The function of several reinforcing ribs 222 is to provide lateral limiting and support for the circuit board 3, making the circuit board 3 less prone to shaking and increasing the stability of the structure.

[0072] In some embodiments, such as Figure 9 As shown, the lighting assembly includes several low beam lamps 91 and several warning lamps 92 mounted on the top surface of the circuit board 3, and the low beam lamps 91 are turned on and off, and the flashing frequency and on and off of the warning lamps 92 are controlled by a button assembly.

[0073] In practice, several warning lights 92 are evenly arranged in a straight line. Each warning light 92 contains three warning colors and is controlled by a button assembly to adjust the flashing frequency or constant illumination state of the warning lights 92. Several low beam lights 91 are located on both sides of the warning lights 92 and are also controlled by the button assembly to adjust the on / off state of the low beam lights 91. Furthermore, the button assembly controls the flashing frequency and on / off state of the warning lights 92, the on / off state of the low beam lights 91, the start / stop, forward / reverse rotation, and speed control of the motor 5, as well as timing and countdown functions. For example, the lights can work in conjunction with the rotating arm 6 to create a timing effect. When the rotating arm 6 has rotated for half an hour, a light will illuminate as a reminder, and this can be controlled by the button assembly to turn it on and off.

[0074] In some embodiments, such as Figure 5 , Figure 9 , Figure 10 , Figure 11 As shown, the button assembly includes several buttons located in the receiving cavity 22, several button slots 223 formed on the side wall of the receiving cavity 22, several limiting protrusions 212 mounted on the top surface of the base plate 21, several travel grooves 32 formed on the edge of the circuit board 3, and a switch 33 installed in each travel groove 32. The positions of the travel grooves 32 and the button slots 223 are matched, and the number of buttons, switches 33, travel grooves 32, and button slots 223 are matched. Figure 3 , Figure 11 As shown, the button includes a pressing part 34 and a T-shaped travel part 35; the top of each travel part 35 is located in the corresponding travel groove 32, the bottom is located between the corresponding limiting protrusion 212 and the inner wall of the receiving cavity 22, and the outer side is provided with a contact 351; each pressing part 34 is inserted into the corresponding button slot 223 and is located outside the contact 351 of the corresponding travel part 35.

[0075] In practice, the pressing part 34 of the button is made of rubber and is fixed in the button slot 223 by rubber coating. The pressing part 34 and the travel part 35 are separate, not fixedly connected. The top of the travel part 35 is limited by the travel groove 32. When the pressing part 34 is pressed, it squeezes the contact 351 of the corresponding travel part 35, and the travel part 35 moves towards the corresponding travel groove 32, thereby contacting the switch 33 in the travel groove 32 and pressing the switch 33 to realize the button function. When the pressing part 34 is released, it returns to its original position due to the properties of the rubber material.

[0076] Furthermore, the number of buttons is at least one, preferably three. Taking the three buttons in the attached diagram as an example: the left button is used to control the low beam headlight 91 to turn on and off, the middle button is used to control the motor 5 to start and stop, and the right button is used to control the warning light 92 to turn on and off; or, the left button is used to control the illumination intensity of the low beam headlight 91, the middle button is used to control the speed of the motor 5, and a long press can realize the forward and reverse rotation adjustment of the motor 5, and the right button is used to control the flashing frequency and constant illumination of the warning light 92.

[0077] Let's take a single button as an example: A long press switches between modes. For instance, a long press enters mode selection mode, allowing you to choose the control mode based on the number or color of the illuminated warning lights 92. Specifically, first, long press this button; all 92 warning lights will illuminate, indicating entry into mode selection. Then, press the button once; the low beam headlight 91 will illuminate a single red light, indicating entry into motor 5 mode. After a few seconds, the mode will lock, allowing control of only motor 5. For example, a single press starts motor 5 rotating forward, two presses adjust the speed, three presses reverse the direction, and four presses stop the motor. A long press again re-enters mode selection, allowing you to switch between warning light 92 control mode and low beam headlight 91 control mode based on the number and color of the illuminated lights.

[0078] In other embodiments, such as Figure 9 , Figure 10 As shown, the edge of the circuit board 3 is also provided with a number of support grooves 36. Each support groove 36 is located between two adjacent stroke grooves 32 and is supported by the top of the corresponding reinforcing rib 222.

[0079] In practice, the installation area of ​​the button assembly is supported by reinforcing rib 222, which can improve the stability of pressing.

[0080] In some embodiments, such as Figure 12 As shown, the motor 5 has two lugs on both sides, each lug having a connecting hole, and a bolt is installed in the connecting hole. Figure 5 As shown, two connecting parts 213 are installed on the top surface of the base plate 21. Each connecting part 213 is cylindrical and has threads on its inner wall. The bolt passes through the corresponding connecting hole and is connected to the corresponding connecting part 213 by threads.

[0081] In some embodiments, such as Figure 9 As shown, the circuit board 3 has two battery connection slots 37, and the battery 4 has two battery connection pieces 41 installed on it, which are respectively inserted into the corresponding battery connection slots 37.

[0082] In practice, the circuit board 3 and the battery 4 are bonded together with an adhesive (the adhesive is 3M backing adhesive), and the circuit board 3 and the battery 4 are electrically connected through two battery connecting pieces 41, thereby supplying power to the battery 4.

[0083] In some embodiments, such as Figure 1 , Figure 17 As shown, the upper cover 1 is provided with a number of transparent rectangular frames 11 and a number of lenses 12; the transparent rectangular frames 11 are matched with the size and number of warning lights 92; the lenses 12 are in the shape of upward-convex semicircles, and the size and number of low beam lights 91 are matched with the size and number of low beam lights 91.

[0084] In practice, the transparent rectangular frame 11 is designed to allow the light from the warning light 92 to radiate outwards without being obstructed by the top cover 1. The lens 12 acts as a lampshade for the low beam headlight 91. Because the lens 12 is a convex semi-circular shape with its edges concave downwards, it does not block the light transmitted through the bottom of the lens 12. If the lens 12 were flat, its bottom would be too thick, causing some of the light from the low beam headlight 91 emitted through the lens 12 to be blocked. Furthermore, the rectangular frame 11, lens 12, and top cover 1 are all made of the same material: plastic.

[0085] In other embodiments, such as Figure 17 As shown, the bottom surface of the upper cover 1 is provided with a recessed honeycomb structure 13 to soften light and direct light, while making the structure stable and reducing the weight of the upper cover 1.

[0086] In some embodiments, the upper cover 1 and the lower cover 2 are fixedly connected in a non-removable manner by ultrasonic welding.

[0087] In some embodiments, such as Figure 3 As shown, a rubber ring 27 is installed on the bottom edge of the lower cover 2.

[0088] In practice, since one end of the rotating cavity 23 faces the palm of the human hand during use, the rubber ring 27 is located at the edge of the lower cover 2 to prevent the edge of the lower cover 2 from directly contacting the palm and to improve the tactile feel.

[0089] In other embodiments, since excessive noise should not occur during the rotation of the motor 5 to avoid affecting the user's attention, the present invention can be made noise-reducing. Specifically, sound-absorbing cotton can be provided on the inner bottom surface of the lower cover 2, or other means can be used to achieve this.

[0090] In summary, by holding this invention in the user's palm, the rotation state of the rotating arm 6 can be changed through timer, timing, forward / reverse rotation, and speed control. This allows the touch head 7 to stimulate the palm, enhancing personal focus, especially when the user is lost in thought or distracted. The changes in stimulation of the palm by this invention can bring the mind back to a focused state. Furthermore, the rotation radius of the rotating arm 6 can be adjusted to touch different parts of the palm, changing the pressure point and thus focusing the user's attention and thoughts on the hand, achieving a concentration effect, especially effective during meditation. In addition, this invention also features a low-beam lamp 91 and a warning light 92, providing a light source in dark environments. It can also be used as a power bank via the charging component, offering low power consumption and portability.
