Description

Technical Field

[0001] The present invention relates to the technical field of smart wearable devices, and in particular to a wrist-worn device. Background Art

[0002] The development of smart wearable devices is changing with each passing day. Market users have increasing demands for upgraded appearance and functions of smart wearable devices. At the same time, they also put forward new requirements for the price and reliability of smart wearable devices. Products with lower prices and higher reliability are more likely to be recognized by market users.

[0003] As an important member of the smart wearable device market that has attracted much attention, wrist-worn devices have been widely accepted by market users and have become products that many users wear frequently in their work and daily lives. In wrist-worn devices, the key module, which plays the role of implementing hardware interactive functions, is an indispensable part. The key module generally includes an operation key and an electronic key. The operation key has a shaft portion that penetrates the device housing and a cap portion that is exposed from the device housing. The electronic key is built into the device housing and is located in the axial direction of the operation key shaft portion. When the operation key is pressed, its shaft portion contacts the electronic key, causing the pot piece of the electronic key to deform and turn on the circuit where the electronic key is located, allowing the device to respond to the pressing operation of the operation key and perform the corresponding interactive function.

[0004] In the related art, a wrist-worn device housing houses a motherboard and a button bracket. A flexible flat cable extends from the motherboard and is secured to the button bracket. The aforementioned electronic buttons are attached to the side of the flexible cable facing away from the button bracket. To fill the gap between the shaft of the operating button and the electronic button, a key pad is placed between the shafts of the electronic and operating buttons. Therefore, in addition to the operating buttons, electronic buttons, and motherboard, the button module also includes at least the aforementioned button bracket, flexible flat cable, and key pad. This results in a large number of components, a complex structure, and numerous, time-consuming, and costly assembly procedures for each component within the module. This makes it difficult to control and reduce the manufacturing costs of the wrist-worn device. Summary of the Invention

[0005] The main purpose of the present invention is to provide a wrist-worn device, aiming to simplify the structure of the key module and reduce the manufacturing cost of the wrist-worn device.

[0006] To achieve the above objectives, the present invention provides a wrist-worn device, comprising:

[0010] a mainboard, which is disposed in the cavity; and

[0011] The electronic button is arranged on the side of the main board facing the movable part. When the operation button is pressed, the movable part is driven to move and press the electronic button.

[0012] In one embodiment of the present invention, the movable member is rotatably connected to the main body, and the electronic key is located on one side of the moving direction of the operating key.

[0013] In one embodiment of the present invention, a side wall of the cavity is provided with a convex assembly portion, the assembly portion is provided with a key slot, and the key slot has a first notch open toward the mainboard;

[0014] Part of the structure of the operating button, the electronic button and the movable part are located in the button groove, and the movable part is rotatably connected to the assembly part.

[0015] In one embodiment of the present invention, a shaft groove is provided on a side of the assembly portion facing the mainboard, the shaft groove is provided close to a side wall of the cavity, and a cover plate is provided in the cavity to cover the notch of the shaft groove;

[0016] A rotating shaft is provided at one end of the movable part close to the operation button. At least a part of the rotating shaft is accommodated in the shaft groove and is rotatably limited between the groove wall of the shaft groove and the cover plate.

[0017] In one embodiment of the present invention, the key slot further has a second slot open toward the operation key, and the second slot is communicated with the first slot;

[0018] A stop step is provided on the side of the assembly portion facing the mainboard, and the stop step is provided close to the second notch;

[0019] A stop portion is provided at one end of the movable part away from the operating button, and the stop portion is located between the stop step and the main board.

[0020] In one embodiment of the present invention, a pressing portion is protruding from a side of the movable member facing the electronic key, and the pressing portion is used to press the electronic key.

[0021] In one embodiment of the present invention, the operating button includes an elastic member and a cap portion and a shaft portion connected thereto;

[0022] The outer wall of the main body is provided with a limiting groove, the shaft portion is movably arranged on the bottom wall of the limiting groove and partially extends into the cavity; at least a part of the structure of the cap portion is accommodated and limited in the limiting groove;

[0023] The elastic member is limited between the cap portion and the bottom wall of the limiting groove, and is used for applying a force along the axial direction of the shaft portion to the cap portion.

[0024] In one embodiment of the present invention, the material of the cap portion is different from that of the shaft portion, and the cap portion and the shaft portion are an integrally formed structure.

[0025] In one embodiment of the present invention, a slot is provided on the outer peripheral wall of one end of the operating button extending into the cavity;

[0026] The operating button also includes a clip spring that is engaged with the card slot. The clip spring is located in the cavity and is used to engage with the side wall stop of the cavity.

[0028] The technical solution of the present invention disposes a mainboard within the cavity of the main body and an electronic key on the mainboard, directly connecting the mainboard and the electronic key. The mainboard serves as a support structure for the electronic key, eliminating the need for a key support bracket for the electronic key and the need for a flexible cable connecting the mainboard and the electronic key. The technical solution of the present invention also disposes a movable member within the cavity of the main body, positioned in the movement path of the operating key. When the operating key is pressed, the operating key pushes the movable member to move, causing it to contact and press the electronic key on the mainboard, thereby establishing electrical connection between the electronic key and the mainboard. This provides the hardware conditions for the wrist-worn device to respond to the pressing of the operating key and execute the corresponding interactive function. The movable member fills the gap between the operating key and the electronic key, providing feedback to the user through the movable member and the operating key when the user presses the operating key, thereby improving the user's operating experience with the operating key. Because the technical solution of the present invention uses movable parts to replace the button bracket, soft cable and button rubber pad in the original wrist-worn device, the structure of the button module in the wrist-worn device is extremely streamlined, the number of components of the button module is small, the assembly procedures are few, the assembly time is short, and the assembly cost is low, which can greatly reduce the manufacturing cost of the wrist-worn device and improve the production efficiency of the wrist-worn device.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0040] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. The meanings of "and / or" and "and / or" appearing throughout the text are the same, both indicating that three parallel solutions are included. Taking "A and / or B" as an example, it includes Solution A, or Solution B, or a solution in which both A and B are satisfied. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0041] The present invention proposes a wrist-worn device, combined with Figure 1 and Figure 2 As shown, the wrist-worn device includes a main body 1, an operation button 2, a movable part 3, a main board 4 and an electronic button 5. A cavity 1a is provided in the main body 1; the operation button 2 is movably arranged in the main body 1 and partially extends into the cavity 1a; the movable part 3 is movably arranged in the cavity 1a, and part of the structure of the movable part 3 is located on the moving path of the operation button 2. The main board 4 is arranged in the cavity 1a; the electronic button 5 is arranged on the side of the main board 4 facing the movable part 3. When the operation button 2 is pressed, it drives the movable part 3 to move and press the electronic button 5.

[0042] In this embodiment, the wrist-worn device includes, but is not limited to, a smartwatch or smart bracelet. The main body 1 of the wrist-worn device is used to display information, such as clock information, incoming call information, and text messages. The main body 1 is equipped with a display screen, such as an LCD or OLED display, to enable this display function. The main body 1 includes a housing that encloses the aforementioned cavity 1a. Cavity 1a is used to accommodate the functional modules of the wrist-worn device, such as the aforementioned movable member 3, mainboard 4, and electronic buttons 5.

[0043] The wrist-worn device also includes a wristband connected to the main body 1 and used to secure the main body 1 to the user's wrist. The wristband is connected to the main body 1 using a detachable connection method such as a snap-on or plug-in connection to facilitate wristband replacement. Taking a smartwatch as an example, the main body 1 is the watch face of the smartwatch, and the wristband is the watch strap of the smartwatch.

[0044] The operation button 2 is used to activate the interactive functions of the wrist-worn device when pressed or rotated. Specifically, the operation button 2 has a cap portion 21 exposed on the outer surface of the main body 1 and a shaft portion 22 extending into the cavity 1a. A sensor corresponding to the shaft portion 22 of the operation button 2 is located within the cavity 1a. When the cap portion 21 of the operation button 2 is pressed or twisted, the sensor detects the linear or angular displacement of the shaft portion 22 of the operation button 2 and sends a corresponding electrical signal to the main board 4, so that the main board 4 can control the display screen to display the corresponding interactive interface based on the electrical signal. The main body 1 defines an axial hole that connects the outside world and the cavity 1a. The shaft portion 22 of the operation button 2 is disposed within the axial hole and slidably engages with the inner circumferential wall of the axial hole. The outer circumferential wall of the operation button 2 may also be sleeved with a sealing ring, which abuts against the inner circumferential wall of the axial hole to achieve a sealed fit between the operation button 2 and the inner circumferential wall of the axial hole, thereby providing waterproof and dustproof protection for the functional modules within the cavity 1a.

[0045] The movable member 3 is used to fill the idle travel between the operating button 2 and the electronic button 5 and optimize the torque exerted by the operating button 2 on the electronic button 5, thereby reducing the travel of the operating button 2 when pressed. This reduces the volume of the key module consisting of the operating button 2, the electronic button 5, the movable member 3, and the mainboard 4, and ultimately the body 1 of the wrist-worn device. When subjected to force from the operating button 2, the movable member 3 moves within the cavity 1a and applies pressure to the electronic button 5. The electronic button 5 acts as a circuit switch for the circuit in which it resides. When pressed, the electronic button 5 connects the circuit between the electronic button 5 and the mainboard 4. At this point, the mainboard 4 controls the corresponding interactive module to implement its interactive functions, such as controlling the display screen to display the corresponding interactive interface.

[0046] In this embodiment, the movable member 3, the operating button 2, and the electronic button 5 can be arranged in a variety of ways: for example, the electronic button 5 is located on the moving path of the operating button 2, the movable member 3 is located between the operating button 2 and the electronic button 5, and is slidably connected to the main body 1 by means of a rail groove. When the operating button 2 is pressed, the movable member 3 is pushed toward the electronic button 5 and presses the electronic button 5. For another example, the electronic button 5 is located above or below the operating button 2 and the movable member 3. The movable member 3 is an L-shaped structure, and its top corner is rotatably connected to the main body 1 by a hole and shaft. The two ends of the movable member 3 are respectively arranged near the electronic button 5 and the operating button 2. When the operating button 2 is pressed, the movable member 3 is pushed to rotate, so that the end of the movable member 3 near the electronic button 5 presses the electronic button 5. In this embodiment, the electronic button 5 includes but is not limited to a pot button and a membrane button.

[0047] This embodiment disposes a motherboard 4 within the cavity 1a of the main body 1 and an electronic key 5 on the motherboard 4, directly connecting the motherboard 4 and the electronic key 5. The motherboard 4 serves as a support structure for the electronic key 5, eliminating the need for a key support bracket for the electronic key 5 and the need for a flexible flat cable connecting the motherboard 4 and the electronic key 5. The present invention also disposes a movable member 3 within the cavity 1a of the main body 1, positioned in the movement path of the operating key 2. When the operating key 2 is pressed, the operating key 2 pushes the movable member 3 to move, causing it to contact and press the electronic key 5 on the motherboard 4, thereby establishing electrical continuity between the electronic key 5 and the motherboard 4. This provides the hardware conditions for the wrist-worn device to respond to the pressing of the operating key 2 and execute the corresponding interactive function. The movable member 3 fills the idle travel between the operating key 2 and the electronic key 5, providing a certain amount of feedback force to the user when the operating key 2 is pressed, thereby improving the user's operating experience with the operating key 2. Because the button module in the embodiment scheme uses the movable part 3 to replace the button bracket, soft cable and button rubber pad in the original wrist-worn device, the structure of the button module in this wrist-worn device is extremely streamlined, the number of components of the button module is small, the assembly procedures are few, the assembly time is short, and the assembly cost is low, which can greatly reduce the manufacturing cost of the wrist-worn device and improve the production efficiency of the wrist-worn device.

[0048] It is worth noting that due to the objective existence of geometric tolerances generated during the assembly of various components, the greater the number of components in the key module used to implement the interactive press function of the wrist-worn device, the greater the cumulative tolerances generated after the components are assembled. Consequently, the difference in the feel of the operation button 2 when pressed on different wrist-worn devices will be more pronounced, which will affect the product quality of the wrist-worn devices shipped. Furthermore, when a key rubber pad is used in the key module of the wrist-worn device to fill the empty travel between the operation button 2 and the electronic button 5, the operation button 2 is frequently pressed for a long time, and the key rubber pad is repeatedly deformed, which significantly reduces its service life. Its structural reliability will also be difficult to guarantee, and the pressing feel of the operation button 2 will be severely degraded after long-term use. However, this embodiment simplifies the structure of the key module and reduces the number of components in the key module, thereby reducing the cumulative tolerances between the components after assembly and ensuring the product's factory quality. This embodiment also replaces the immovable key rubber pad with a movable movable part 3, and replaces the movable part 3 made of flexible material with a movable part 3 made of hard material, which can avoid the problem of unreliable structure of the key rubber pad and deterioration of the pressing feel of the operation key 2 after long-term use, thereby extending the service life of the above-mentioned key module and stabilizing the pressing feel of the operation key 2.

[0049] In one embodiment of the present invention, Figure 1 and Figure 2As shown, the movable member 3 is rotatably connected to the main body 1 , and the electronic button 5 is located on one side of the moving direction of the operation button 2 .

[0050] In this embodiment, the movable member 3 can be rotatably connected to the inner wall of the cavity 1a of the main body 1 through a hole-shaft fit. The movable member 3 has two ends respectively adjacent to the electronic key 5 and the operation key 2. The movement path of the operation key 2 is a linear movement path when it is pressed. The end of the movable member 3 adjacent to the operation key 2 is located on the movement path of the operation key 2. The movable block 3 can have a block or plate-like structure, which is not limited here.

[0051] The electronic button 5 is located on one side of the linear moving path of the operation button 2, that is, Figure 1 or Figure 2 When the operation button 2 is pressed, the operation button 2 moves linearly and pushes the movable member 3 to rotate relative to the main body 1. The end of the movable member 3 close to the electronic button 5 presses the electronic button 5.

[0052] This embodiment optimizes the torque exerted by the operating button 2 on the electronic button 5 by rotating the movable member 3 disposed within the cavity 1a, thereby converting a short-distance displacement of the operating button 2 into a large-angle rotation of the movable member 3, thereby achieving the pressing of the electronic button 5. This helps shorten the length of the operating button 2, reduces the material cost and volume of the operating button 2, and enhances the operating experience of the operating button 2. In addition, the electronic button 5 can be positioned in the spare space above or below the operating button 2, rather than in the direction of movement of the operating button 2. This can reduce the extended length of the entire structure consisting of the operating button 2, movable member 3, and electronic button 5, and reduce the volume of the entire structure consisting of the operating button 2, movable member 3, and electronic button 5, thereby reducing the volume and material cost of the wrist-worn device.

[0053] In one embodiment of the present invention, Figure 4 As shown, the side wall of the above-mentioned cavity 1a is protruded with an assembly part 11, and the assembly part 11 is provided with a key groove 11a, and the key groove 11a has a first notch 11a1 open toward the main board 4; part of the structure of the operation key 2, the electronic key 5 and the movable part 3 are located in the key groove 11a, and the movable part 3 is rotatably connected to the assembly part 11.

[0054] In this embodiment, the assembly portion 11 can be integrally formed with the housing of the main body 1. The key slot 11a of the assembly portion 11 is used to accommodate part of the structure of the operating key 2. The first notch 11a1 of the key slot 11a is used to allow the movable member 3 to pass through. The sidewalls of the key slot 11a also guide the movement of the movable member 3, preventing the movable member 3 from shaking during rotation, ensuring accurate alignment of the movable member 3 with the electronic key 5, and accurately pressing the electronic key 5 through the movable member 3 when the operating key 2 is pressed. The movable member 3 is rotatably connected to the assembly portion 11 through a hole-shaft fit or other method. The rotational connection between the movable member 3 and the assembly portion 11 can be located near the connection between the assembly portion 11 and the sidewall of the cavity 1a. The electronic key 5 is located near the free end of the movable member 3, away from the rotational connection between the movable member 3 and the assembly portion 11.

[0055] The main board 4 can cover the first notch 11a1 of the key slot 11a, so that the key slot 11a and the main board 4 enclose a relatively closed space. The assembly part 11 and the main board 4 can isolate and protect the operation key 2, movable part 3 and electronic key 5 in the key slot 11a, avoiding the functional module located outside the key slot 11a in the cavity 1a from interfering with the operation of the above-mentioned key module, thereby ensuring the reliability of the above-mentioned key module during operation.

[0056] In one embodiment of the present invention, Figure 4 As shown, the above-mentioned assembly portion 11 is provided with an axis groove 11b on the side facing the main board 4, and the axis groove 11b is arranged close to the side wall of the cavity 1a. A cover plate is provided in the cavity 1a to cover the notch of the axis groove 11b; the movable part 3 is provided with a rotating shaft 31 at one end close to the operation button 2, and at least part of the structure of the rotating shaft 31 is accommodated in the axis groove 11b and is rotatably limited between the groove wall of the axis groove 11b and the cover plate.

[0057] In this embodiment, the shaft groove 11b is used to accommodate the rotating shaft 31 of the movable part 3. The shaft groove 11b has a notch open to the main board 4. When the movable part 3 is installed on the assembly portion 11, it is only necessary to move the rotating shaft 31 of the movable part 3 downward and pass through the notch of the shaft groove 11b to be placed in the shaft groove 11b. Then, a cover plate is installed on the main body 1 so that the cover plate covers the notch of the shaft groove 11b and the notch of the key groove 11a, so that the rotating shaft 31 of the movable part 3 is limited in the space formed by the main board 4 and the groove wall of the shaft groove 11b. The installation of the movable part 3 is very convenient and can improve the assembly efficiency of the wrist-worn device. Among them, the above-mentioned main board 4 can be used as the cover plate. In this way, the main board 4 already set in the main body 1 is used to limit the rotating shaft 31 in the shaft groove 11b, without the need to separately design and assemble other cover plate structures. This is conducive to simplifying the number and structure of components of the wrist-worn device and improving the assembly efficiency of the wrist-worn device.

[0058] The assembly portion 11 in this embodiment may be provided with two oppositely arranged shaft grooves 11b, and the two shaft grooves 11b are located on both sides of the operation button 2 and the electronic button 5. The outer wall of the movable part 3 is provided with two protruding shafts 31 corresponding to the two shaft grooves 11b, and each shaft 31 is accommodated in an shaft groove 11b. The structure of the movable part 3 located between the two shafts 31 is accommodated in the key groove 11a between the two shaft grooves 11b.

[0059] In one embodiment of the present invention, Figure 4 As shown, the above-mentioned key slot 11a also has a second slot 11a2 open toward the operation button 2, and the second slot 11a2 is connected to the first slot 11a1; a stop step 111 is provided on the side of the assembly portion 11 facing the main board 4, and the stop step 111 is arranged close to the second slot 11a2; a stop portion 33 is provided at the end of the movable part 3 away from the operation button 2, and the stop portion 33 is located between the stop step 111 and the main board 4.

[0060] In this embodiment, the second notch 11a2 is used to avoid the free end of the movable member 3, and the first notch 11a1 and the second notch 11a2 are connected to form the notch of the key slot 11a. The free end of the movable member 3 is formed with a stop portion 33, which can be a boss structure or a step structure adapted to the stop step 111. Figure 1 As shown, when the movable part 3 rotates and its free end moves away from the main board 4, the stop step 111 will stop the stop portion 33 to prevent the movable part 3 from continuing to rotate and causing damage to the functional modules around it. For example, the main board 4 and the display screen are respectively located on the upper and lower sides of the movable part 3. When the free end of the movable part 3 moves away from the main board 4, the display screen may be scratched; thereby, the reliability and safety of the key module when in use can be improved.

[0061] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, a pressing portion 32 is protruded from the side of the movable member 3 facing the electronic key 5 , and the pressing portion 32 is used to press the electronic key 5 .

[0062] In this embodiment, the pressing portion 32 is a raised structure on the free end of the movable member 3. By aligning the pressing portion 32 with the portion to be pressed 32 on the electronic key 5, the movable member 3 can accurately and reliably press the electronic key 5. The pressing portion 32 can be made of a flexible material, while the movable member 3 can be made of a rigid material. The pressing portion 32 and the movable member 3 can be integrally formed using a two-color injection molding process. In this case, the pressing portion 32 can deform when pressed against the electronic key 5, thereby buffering the pressure applied by the movable member 3 to the electronic key 5, preventing damage to the electronic key 5 and extending the service life of the electronic key 5. The pressing portion 32 can also be integrally formed with the movable member 3 using the same material to reduce the design and processing costs of the movable member 3.

[0063] In one embodiment of the present invention, Figure 3 As shown, the above-mentioned operating button 2 includes an elastic member 23 and a cap portion 21 and a shaft portion 22 connected thereto;

[0064] The outer wall of the main body 1 is provided with a limiting groove 1b, and the shaft portion 22 is movably arranged on the bottom wall of the limiting groove 1b and partially extends into the cavity 1a; at least part of the structure of the cap portion 21 is accommodated and limited in the limiting groove 1b;

[0065] The elastic member 23 is limited between the cap portion 21 and the bottom wall of the limiting groove 1 b and is used to apply a force along the axial direction of the shaft portion 22 to the cap portion 21 .

[0066] In this embodiment, when the cap 21 is pressed and used, the cap 21 squeezes the elastic part 23 to deform, causing the elastic part 23 to accumulate elastic potential energy. When the pressing force on the cap 21 is removed, the elastic part 23 releases the elastic potential energy to push the cap 21 to reset. In this way, the cap 21 can be reset after being pressed, so that the operation button 2 can be pressed and used repeatedly.

[0067] Optionally, the bottom wall of the limiting groove 1b may be provided with a positioning protrusion, and the side of the cap 21 facing the elastic member 23 may be provided with a positioning groove, one end of the elastic member 23 being limited in the positioning groove, and the other end of the elastic member 23 being sleeved on the positioning protrusion, thereby achieving the positioning of the elastic member 23, preventing the elastic member 23 from non-axial movement relative to the cap 21 and the main body 1, and ensuring the reliability of the connection and cooperation between the elastic member 23, the cap 21 and the main body 1. The number of elastic members 23 can be multiple, each elastic member 23 is arranged around the shaft portion 22, and each elastic member 23 is limited between the cap 21 and the bottom wall of the limiting groove 1b. The provision of multiple elastic members 23 allows the portion of the cap 21 on the axial side of the shaft portion 22 to be evenly subjected to the elastic force from each elastic member 23, thereby allowing the cap 21 to maintain a linear movement state during the pressing and resetting process, improving the smoothness of the movement of the operation button 2 and improving the operating experience of the operation button 2.

[0068] In one embodiment of the present invention, Figures 1 to 3 As shown, the material of the cap portion 21 is different from that of the shaft portion 22 , and the cap portion 21 and the shaft portion 22 are an integrally formed structure.
