[0051] The embodiment of the present invention provides a wrist-worn device, combined with Figures 1 to 3 As shown, the wrist-worn device includes a shell component 1, a locking component 2 and a display body 3; wherein the shell component 1 includes a base 11 and a wristband 12 connected to the base 11, and the base 11 is provided with a receiving groove 11a; the locking component 2 includes a button 21 and a locking member 22 movably provided on the base 11 and transmission-connected; the display body 3 is accommodated in the receiving groove 11a, and the locking member 22 cooperates with the bottom wall of the receiving groove 11a to clamp and fix the display body 3, and when the button 21 is pressed, it can drive the locking member 22 to separate from the display body 3.

[0052] In this embodiment, the wrist-worn device includes but is not limited to a wearable device such as a smart watch and a bracelet that can be worn on a human wrist. The base 11 in the housing assembly 1 of the wrist-worn device is provided with a receiving groove 11a for accommodating the display body 3. The wristband 12 in the housing assembly 1 is used to realize the wearing and fixing of the display body 3 on the human wrist. The display body 3 of the wrist-worn device includes a display screen 32 for displaying information such as clocks, text messages, and calls, and a rechargeable power module for powering the display screen 32. The display body 3 is also provided with a charging interface and / or a wireless charging coil for charging the power module, so that the display body 3 can be charged in a wired or wireless manner. In order to protect the display screen 32, the charging module, and the circuit structures related thereto from damage, the display body 3 also includes a housing 31, which is provided on the periphery of the display screen 32, the charging module, and the above-mentioned circuit structures. The housing 31 wraps and protects the display screen 32, the charging module, and the circuit structures related thereto. The housing 31 is provided with a mounting groove 31a, and the display screen 32 is accommodated and limited in the mounting groove 31a and is displayed to the outside through the notch of the mounting groove 31a. The wristband 12 can be connected to the base 11 by means of a spring ear structure, or by means of a snap connection. The wristband 12 can be an integrated strap, with two ends of the strap connected to two opposite ends of the base 11; or, the wristband 12 includes two separate straps, the two straps are connected to two opposite ends of the base 11, and the two straps are connected by a snap-fit ​​structure in which a buckle and a snap hole cooperate.

[0053] The locking assembly 2 is used to fix the display body 3 on the base 11. The button 21 in the locking assembly 2 is movably arranged in the base 11 and has a pressing portion exposed on the outside of the base 11, and the pressing portion is used for the user to contact and press. The locking member 22 in the locking assembly 2 can be slidably connected with the base 11 through the rail groove, or the locking member 22 can also be rotatably connected with the base 11 through the hole shaft. The locking member 22 is also connected to the button 21 through a transmission member 23 such as a rotating shaft and a gear. When the button 21 is not pressed, the part of the locking member 22 located above the bottom wall of the groove 11a cooperates with the bottom wall of the groove 11a to clamp and fix the display body 3, so that the display body 3 is positioned in the groove 11a of the base 11, so that the display body 3 can be reliably worn on the user's wrist through the wristband 12. At this time, the display body 3 is in a locked state. When the button 21 is pressed, the button 21 drives the locking member 22 to move relative to the base 11, and the locking member 22 can be separated from the display body 3, so that the display body 3 is no longer clamped by the locking member 22 and the bottom wall of the receiving groove 11a, and the display body 3 can be removed from the base 11. At this time, the display body 3 is in an unlocked state. Therefore, the user can switch the display body 3 from the locked state to the unlocked state by pressing the button 21, and then the display body 3 can be taken out for charging or use without taking off the wristband 12.

[0054] The locking assembly 2 has various structural forms. In one embodiment, the locking assembly 2 includes a spring, a transmission block, and the two locking members 22 mentioned above. The two locking members 22 are respectively located at the two ends of the connection between the base 11 and the wristband 12. Each locking member 22 is slidably connected to the base 11 through the rail groove, and can be lifted and lowered relative to the base 11; the spring connects the locking member 22 and the base 11 and is located between the locking member 22 and the base 11; the transmission block is U-shaped, and the two ends of the transmission block extend to the bottom of the two locking members 22 and are located between the locking member 22 and the base 11; both ends of the transmission block are provided with a first guide Inclined surface, each locking member 22 is provided with a second guiding inclined surface corresponding to the first guiding inclined surface, and the spring applies an elastic force to the locking member toward the first guiding inclined surface, that is, downward, so that the second guiding inclined surface abuts against the first guiding inclined surface; a downward pressing convex ridge is provided on the opposite side of the two locking members 22, and under the elastic action of the spring, the two downward pressing convex ridges abut against the side of the display body 3 facing away from the receiving groove 11a, so that the two locking members 22 can fix the display body 3 by the cooperation of the downward pressing convex ridge and the bottom wall of the receiving groove 11a; the button 21 is located between the two locking members 22 and is connected to the transmission block. When the button 21 is pressed, the button 21 drives the transmission block to move along the pressing direction of the button 21. The transmission block pushes the two locking members 22 upward through the sliding cooperation of the first guide slope and the second guide slope, and the spring is stretched. As the button 21 is pressed deeper, the transmission block lifts the two locking members 22 to a position separated from the display body 3. At this time, the display body 3 can be taken out from the space formed between the base 11 and the two downward pressing convex eaves. After the display body 3 is taken out, under the elastic action of the spring, the locking member 22 moves downward and resets. The locking assembly 2 that drives the two locking members 22 to move up and down by the button 21 to realize the switching of the display body 3 between the locked state and the unlocked state only includes two components, the transmission block and the spring. The structure of the locking member 22 is extremely simple. The transmission cooperation between the button 21 and the locking member 22 is realized by the transmission block monomer. The locking assembly 2 has a low failure rate, is practical and reliable, can greatly reduce the material cost of the locking assembly 2, and prolongs the service life of the locking assembly 2. In addition, the button 21 can unlock the display body 3 by pressing it with one hand, and the display body 3 is also very convenient to access.

[0055] The technical solution of this embodiment is to set a groove 11a that can accommodate the display body 3, and a button 21 and a locking member 22 that can move relative to the base 11 on the base 11 of the wrist-worn device, so that the button 21 is transmission-connected with the locking member 22. When the display body 3 is installed in the groove 11a of the base 11, the display body 3 is clamped and fixed by the locking member 22 and the bottom wall of the groove 11a. When the display body 3 needs to be taken out alone, the button 21 is pressed to drive the locking member 22 to separate from the display body 3, and the locking state of the display body 3 on the base 11 is released with one click, so that the display body 3 can be taken out from the base 11 alone for charging and use without untying the wristband 12. This greatly reduces the number of times the wristband 12 is untied / fastened, and effectively improves the service life of the wristband 12.

[0056] It is worth pointing out that during the process of technical research and development, the applicant discovered that because the wrist-worn device is worn and fixed on the human wrist, such as worn on the left wrist of the human body, the left hand cannot participate in the unlocking and removal process of the display body 3, and must rely on the right hand to perform the unlocking operation. Therefore, how to conveniently unlock and remove the display body 3 with one hand has become a technical problem that needs to be solved urgently. During the research and development process, the applicant has proposed a variety of unlocking solutions for the display body 3: for example, a button 21 is respectively arranged at the opposite ends of the base 11 (such as the front and rear ends or the left and right ends), two retractable and movable lock tongues are arranged on the side walls of the receiving groove 11a of the base 11, and lock holes corresponding to the two lock tongues are opened on the display body 3, and two movable levers are arranged inside the base 11, each lever is connected to a button 21 and a lock tongue, and when each button 21 is pressed, the lever drives a lock tongue to retract into the base 11, and when the two buttons 21 are pressed at the same time, the double lock tongues retract into the base 11, so that the originally engaged lock tongue and the shrinkage can be disengaged, so that the display body 3 can be unlocked on the base 11, and the double lock tongue design can better fix the display body 3 in the horizontal and vertical directions compared with the single lock tongue design, and the display body 3 is not easy to deviate or flip in the receiving groove 11a, so that the display body 3 can be reliably positioned on the base 11. However, in this solution, the double lock tongues need to be driven by pressing the double buttons 21, which means that the user needs to use the thumb and index finger of the right hand to press the two buttons 21 on the opposite sides of the base 11 in a pinching posture to unlock the display body 3 on the base 11, and the remaining middle finger, ring finger and little finger of the right hand are difficult to cross the index finger joint to take out the display body 3, and in the taking operation, the three fingers are not as flexible as the thumb and index finger, so the taking out of the display body 3 is not convenient enough. For another example, a drawer-like side-opening receiving groove 11a is designed on the base 11, so that the receiving groove 11a also has an upper opening connected to the side opening, and the upper opening is used to allow the display surface of the display body 3 to be exposed to the outside, and a movable button 21 is provided on the side of the base 11 that is away from the side opening of the receiving groove 11a, and a buckle that is transmission-connected to the button 21 is provided in the receiving groove 11a, and a card slot corresponding to the buckle is provided on the display body 3; when the button 21 is pressed, the button 21 drives the buckle to disengage from the card slot, thereby unlocking the display body 3. This solution can unlock the display body 3 with a single button 21, and the structure of the relevant display body 3 is relatively simple, and the volume and cost of the wrist-worn device are easy to control.However, in this solution, the user needs to press the button 21 with the index finger to unlock the display body 3, and then use the thumb to slide the display body 3 from the inside of the groove 11a to the side opening of the groove 11a; or vice versa, press the button 21 with the thumb and slide the display body 3 with the index finger (according to general usage scenarios, whether to press the button 21 with the index finger or the thumb depends on whether the side opening of the groove 11a faces or faces away from the user's body); in short, the thumb and index finger move apart during the process of taking out the display body 3, which is not in line with the habit of people taking objects by hand, and the taking out of the display body 3 is still not convenient enough.

[0057] Based on the above research and development history of the applicant, the applicant proposed the present embodiment, in which a single button 21 is designed, and the locking member 22 presses downward from the top and cooperates with the bottom wall of the receiving groove 11a to clamp the display body 3 in the receiving groove 11a, so that the user can use one of the commonly used index finger or thumb to press the button 21. When the button 21 is pressed, the locking member 22 moves vertically upward or flips and unlocks the display body 3. At this time, the other of the index finger or thumb can move toward the display body 3. The index finger and the thumb move toward each other and cooperate to pinch the unlocked display body 3 to take the display body 3 out of the receiving groove 11a. This is very consistent with the physiological structure of the human hand and the habit of the human hand to take objects, making the operation of taking the display body 3 very convenient and natural.

[0058] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the locking member 22 in the above embodiment includes two pressing blocks 221 which are rotatably arranged on the base 11 and transmission-connected with the button 21; the two pressing blocks 221 are respectively located at the two ends of the base 11; a pressing portion 2211 is convexly provided on the opposite side of the two pressing blocks 221, and the display body 3 is located between the two pressing blocks 221, and the two pressing portions 2211 cooperate with the bottom wall of the receiving groove 11a to clamp and fix the display body 3; when the button 21 is pressed, the pressing portions 2211 of the two pressing blocks 221 are driven to separate from the display body 3.

[0059] In this embodiment, by respectively arranging the pressing blocks 221 at the opposite ends of the base 11, the two pressing blocks 221 can be synchronously moved downward under the drive of the button 21, and the two ends of the display body 3 are simultaneously pushed downward by the pressing parts 2211 on the two pressing blocks 221, so that both ends of the display body 3 can be clamped and fixed by the pressing blocks 221 and the bottom wall of the groove 11a, which can improve the reliability of the installation and fixation of the display body 3 on the base 11. In addition, the two pressing blocks 221 are connected to the base 11 by a rotation connection such as a hole-shaft match, so that the ends of the two pressing blocks 221 away from the groove 11a can move away from each other when the button 21 is pressed, and a space is formed between the two pressing blocks 221 that gradually expands from the bottom wall of the groove 11a toward the notch of the groove 11a, so that the display body 3 can be taken out upward without being hindered by the pressing parts 2211 of the two pressing blocks 221, which provides convenient conditions for taking the display body 3.

[0060] The locking member 22 in the above embodiment may also include a single pressing block 221 or a plurality of pressing blocks 221:

[0061] When a single pressing block 221 is provided, the pressing block 221 is movably provided at one end of the base 11, and a protrusion extending toward the pressing block 221 may be provided at one end of the receiving groove 11a facing the pressing block 221, and a limited space is formed between the protrusion and the bottom wall of the receiving groove 11a, and one end of the display body 3 is inserted into the limited space and fixed accordingly, and the other end of the display body 3 is clamped and fixed by the pressing block 221 and the bottom wall of the receiving groove 11a. In this solution, because the locking member 22 only includes a single pressing block 221, its structure is simple, which can reduce the material cost of the locking member 22, and can also reduce the laying range and the number of components of the transmission structure between the button 21 and the locking member 22, thereby reducing the volume and manufacturing cost of the wrist-worn device. However, because the protrusion cannot be driven to lift by the button 21, after the display body 3 is unlocked, the user needs to use the thumb and index finger to pinch the end of the display body 3 away from the protrusion to pull the display body 3 obliquely upward from the above-mentioned limited space before taking out the display body 3, which is not convenient enough to take out the display body 3.

[0062] When multiple pressing blocks 221 are provided, the multiple pressing blocks 221 can be arranged around the display body 3, and each pressing block 221 is provided with a pressing portion 2211 extending toward the display body 3. The pressing portion 2211 of each pressing block 221 cooperates with the bottom wall of the groove 11a to clamp and fix the display body 3. When the button 21 is pressed, each pressing block 221 is driven to lift or flip upward, so that the pressing portion 2211 of each pressing block 221 is separated from the display body 3 at the same time, thereby unlocking the display body 3. Multiple pressing blocks 221 cooperate with the bottom wall of the groove 11a to clamp and fix multiple parts of the display body 3, which can greatly improve the reliability of the display body 3 when it is installed and fixed on the base 11. However, because the number of pressing blocks 221 is greater than or equal to 3, each pressing block 221 needs to be connected to the button 21 through a transmission structure, and the material cost and volume of the locking member 22 and the transmission structure connecting each locking member 22 and the button 21 are not easy to control, which is not conducive to the volume and manufacturing cost control of the wrist-worn device.

[0063] Therefore, based on the above research and development considerations, the applicant proposes a technical solution in which the locking member 22 in this embodiment includes two pressing blocks 221. The structural design of the double pressing blocks 221 can take into account the reliability of the display body 3 when it is installed and fixed, the convenience of unlocking and removing the display body 3, and the control of the volume and cost of the wrist-worn device. Among them, each pressing block 221 in the locking member 22 can be driven by the driving method in the previous embodiment, which will not be repeated here.

[0064] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, in the above embodiment, a avoiding surface 2212 is provided on one side of the two pressing blocks 221 facing each other; each avoiding surface 2212 extends in a direction away from the display body 3 , and a avoiding space 2a is formed between the avoiding surface 2212 and the display body 3 .

[0065] In this embodiment, the avoidance surface 2212 and the avoidance space 2a are used to avoid the display body 3 when the pressing block 221 rotates, reduce the interference of the display body 3 on the position of the pressing block 221 when rotating, increase the rotation angle of the pressing block 221, and form a larger space between the two pressing blocks 221 for the display body 3 to enter and exit, so as to facilitate the display body 3 to be placed in or taken out of the receiving groove 11a, and improve the efficiency of installation and removal of the display body 3. Among them, the avoidance surface 2212 can be a curved surface or an inclined surface provided on the pressing block 221; or the avoidance surface 2212 includes the following: Figure 5 and Figure 6The upper curved segment and the lower straight segment are connected as shown; or, the avoidance surface 2212 includes a curved segment and an inclined segment; in short, at least part of the structure of the avoidance surface 2212 extends in the direction away from the display body 3, and forms the above-mentioned avoidance space 2a between the outer wall of the display body 3, and the avoidance space 2a is compressed when the pressing block 221 rotates upward, and the avoidance space 2a expands when the pressing block 221 rotates downward and resets.

[0066] In one embodiment of the present invention, Figure 5 and Figure 6 As shown, a limiting portion 113 is protruding from the bottom wall of the containing groove 11a in the above embodiment; a limiting groove 221a is provided on the side of the bottom wall of the pressing block 221 facing the containing groove 11a, and at least part of the structure of the limiting portion 113 is located in the limiting groove 221a and is spaced from at least one side wall of the limiting groove 221a.
