Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wearable devices, in particular to a watch grain structure and a smart watch. BACKGROUND

[0002] With the rapid development of science and technology, various kinds of smart wearable devices are penetrating into all aspects of people's life, bringing great changes to people's daily perception. The wearable device is not only a hardware device, but also realizes its powerful function through software support and data interaction, cloud interaction. Its application field is very wide, such as medical treatment, fitness and communication, etc. For example, the watch has not only been limited to the functions of viewing time and timing, but also can realize various functions such as telephone, short message, email, photo and music video by implanting intelligent hardware in the watch and connecting to the network through the smart phone system. The smart watch is the extension and expansion of the function of the mobile phone, which brings great convenience to people's daily life.

[0003] When the user wears the smart watch, the watch shell should be as close as possible to the wrist, so that the wearing stability is high, and the user wearing experience is improved. However, the traditional watchband is generally divided into buckle type watchband and split type chain watchband. The buckle type watchband must be disassembled and assembled every time the length is adjusted, which is complicated to operate, and the user experience is poor. The length of each watch chain of the split type chain watchband is fixed, and the user needs to buy accessories or remove the excess watch chain to adjust the length of the watchband, which is complex and may not achieve the appropriate length, affecting the use performance of the smart wearable. And the two above-mentioned ways have the problem that the skin tissue is easily pinched in the process of adjusting the watchband, and for children, the wearing process is difficult, and there is a certain safety hazard. And the adjustment method has many steps, and the operation is difficult, and the length span of the watchband adjustment is large.

[0004] Therefore, how to improve the technical defects existing in the prior art has always been a problem to be solved by ordinary skilled in the art. SUMMARY

[0005] The purpose of the present application is to provide a watch grain structure and a smart watch, which can greatly simplify the user's adjustment steps of the watchband, and the operation is simple and safe.

[0006] The technical scheme provided by the present application is as follows:

[0019] In the natural state, the reset member lifts the cantilever upward, so that the protrusion is embedded in the slot position, to form the locking of the watchband connector;

[0020] In the pressed state, the gear drives the cantilever to move downward, so that the protrusion is separated from the slot position, and the elastic knob drives the rack to move in the rotation process, to adjust the position of the watchband connector relative to the shell.

[0021] In some embodiments, the cantilever comprises two arms symmetrically hinged to the base;

[0022] The free ends of the two arms are provided with sliding seats; and

[0023] The number of reset members is two, which are arranged on the base and are respectively used for sliding cooperation with the sliding seats; and

[0024] The number of protrusions is two, which are respectively arranged on the two arms; and

[0025] The plurality of slots include two rows of slots, respectively arranged on opposite sides of the stroke station;

[0026] The plurality of slots in one row of slots and the plurality of slots in the other row of slots are arranged alternately, and the two rows of slots are respectively used to be engaged with the two protrusions during the movement of the rack driven by the gear.

[0027] In some embodiments, one row of slots on one side of the stroke station includes three slots;

[0028] One row of slots on the other side of the stroke station includes two slots; and

[0029] The two rows of slots are arranged alternately to form five gears;

[0030] During the process of switching from the pressed state to the natural state of the elastic knob, the five gears are selectively engaged with the two protrusions to adjust the length of the watchband.

[0031] In some embodiments, the protrusions are elastically arranged on the arms;

[0032] When the protrusion on one arm is engaged in one slot on one side of the stroke station, the protrusion on the other arm rebounds towards the arm direction under the abutment of the bottom wall of the watchband connector.

[0033] In some embodiments, the watchband connector includes a slider slidingly arranged in the slide and a watchband connecting particle arranged at the end of the slider;

[0034] The stroke station is a sliding hole opened in the slider; and

[0035] The rack is arranged on the side edge of the sliding hole;

[0036] The gear is located inside the sliding hole to engage with the rack, and the elastic knob is synchronously pressed and rotated, so that the gear drives the rack to move, thereby changing the position of the watchband connecting particle relative to the housing to adjust the length of the watchband.

[0037] In some embodiments, the side of the housing away from the watchband connector is provided with a host connecting particle connected to the host;

[0038] And / or

[0039] The housing is in the form of an isosceles trapezoidal block to match the profiles of the host and the watchband.

[0040] In some embodiments, a damping member is arranged between the watchband connector and the housing.

[0044] The central position of the rotating station is provided with a hole position communicated with the slide;

[0045] The gear comprises a gear body and a gear shaft;

[0046] The gear shaft extends to the rotating station through the hole position to interface with the knob body, so as to fix the gear body inside the stroke station and make the gear body engage with the rack.

[0047] The present application also provides an intelligent watch in a second aspect, comprising:

[0048] A host, a watchband, and a watch grain structure connected to the host and the watchband to adjust the telescopic length of the watchband relative to the host;

[0049] The watch grain structure is the above-mentioned watch grain structure.

[0050] The technical effect of the present application is that:

[0051] In the present application, the user only needs to press and synchronously rotate the elastic knob to make the gear drive the rack to reciprocate in the stroke range of the stroke station, so as to provide the power for the forward or backward movement of the watchband connecting piece, thereby adjusting the length of the watchband. When the watchband is adjusted to the appropriate length position, the user only needs to remove the pressing force applied to the elastic knob, and the elastic knob can automatically rebound. At this time, the gear is released from the limiting of the elastic buckle position, so that the elastic buckle position automatically rebounds to be buckled and matched with the slot position corresponding to the upper side thereof, thereby limiting the rotation of the gear. At this time, the gear and the rack are still in engagement, so that the buckling and matching of the elastic buckle position and the slot position can lock the length of the watchband, thereby greatly simplifying the adjustment steps of the user for the watchband, and improving the stability. Especially for children, the portability and safety of the operation of children can be greatly improved, and the situation of muscle tissue being pinched will not occur. Moreover, the stroke range of the elastic knob is limited by the stroke station, which can effectively ensure that the watchband connecting piece will not be separated from the shell, thereby greatly improving the stability and accuracy of the user operation.

Detailed Implementation

[0063] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some of the embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative effort, and other embodiments can also be obtained.

[0064] For the sake of simplicity of the drawings, only the parts related to the present application are shown in each drawing, and they do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown schematically, or only one of them is marked. In this document, "one" not only means "only one", but also means "more than one" situation.

[0065] It should be further understood that the term "and / or" used in the present application and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0066] In this document, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0067] In addition, in the description of the present application, the terms "first", "second", etc. are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0068] According to one specific embodiment provided by the present application, as Figures 1 to 8As shown, the present application provides a watch structure 100 in the first aspect, which can specifically include a housing 1 connected to a host and an adjusting member 2 used to adjust the length of a watchband 200. The housing 1 is provided with a sliding channel 11, and the adjusting member 2 includes an elastic knob, a gear 23, an elastic buckle 24 and a watchband connecting piece 25. The watchband connecting piece 25 is provided with a stroke position 2511 and a plurality of groove positions 2513. The edge of the stroke position 2511 is provided with a rack 2512, and the elastic knob is used to fix the gear 23 to the stroke position 2511, so that the gear 23 and the rack 2512 are engaged. In the natural state of the elastic knob, the plurality of groove positions 2513 are selectively matched with the elastic buckle 24, so as to limit the rotation of the gear 23, so as to form the locking of the watchband connecting piece 25. In the pressed state of the elastic knob, the gear 23 drives the elastic buckle 24 to be separated from the groove position 2513, and the elastic knob drives the gear 23 to drive the rack 2512 to move in the rotation process, so that the watchband connecting piece 25 moves back and forth in the stroke range of the stroke position 2511, so as to adjust the length of the watchband 200.

[0069] In the embodiment, the user only needs to press and synchronously rotate the elastic knob, so that the gear 23 drives the rack 2512 to move back and forth in the stroke range of the stroke position 2511, so as to provide the power for the watchband connecting piece 25 to move forward or backward, thereby forming the adjustment of the length of the watchband 200. When the watchband 200 is adjusted to the appropriate length position, the user only needs to remove the pressing force applied to the elastic knob, and the elastic knob can automatically rebound, at this time, the gear 23 releases the limiting of the elastic buckle 24, so that the elastic buckle 24 automatically rebounds to be buckled and matched with the groove position 2513 corresponding to the upper side thereof, thereby limiting the rotation of the gear 23. At this time, the gear 23 and the rack 2512 are still in the engaged state, therefore, the buckling and matching of the elastic buckle 24 and the groove position 2513 can form the locking of the length of the watchband 200, which can greatly simplify the adjustment steps of the user to the watchband 200, and has high stability. Especially for children, the portability and safety of the operation of the children can be greatly improved, and the situation that the muscle tissue is pinched will not occur. And the rotation range of the elastic knob is limited by the stroke position 2511, which can effectively ensure that the watchband connecting piece 25 will not be separated from the housing 1, thereby greatly improving the stability of the operation of the user and the accuracy of the adjustment of the watchband 200.

[0070] Of course, the present application also provides a smart watch in the second aspect, as shown in Figure 1The smart watch specifically can include a host, a watch band 200 and the watch grain structure 100 provided in the first aspect of the present application. The watch grain structure 100 is connected to the host and the watch band 200 to adjust the extension length of the watch band 200 relative to the host, so that the user can adjust the smart watch to the most comfortable wearing size without taking off the watch band 200, and greatly improves the problem that children have difficulty in wearing and have certain safety hazards, ensuring that children will not pinch the skin tissue during the process of adjusting the size of the watch band 200, and the safety is higher.

[0071] Further, the watch band of the conventional smart watch is generally a buckle type or split type chain structure, and the watch band is usually selected as two, which are connected to the watch ears at opposite ends of the watch dial, and the smart watch is worn by setting a watch buckle between the two watch bands. However, the watch buckle is located between the two watch bands, so that the overall connection of the two watch bands is poor in appearance, affecting the visual experience. And the stability of the watch buckle structure is poor, easy to damage, and the operation is cumbersome, resulting in poor user experience. Most importantly, the skin tissue is easily pinched during the length adjustment process of the watch band, especially for children, which is difficult to wear and has certain safety hazards. Based on this, in the embodiment, as preferred, the watch band 200 can be selected as one, one end of which is connected to the watch ear at one end of the host, and the other end is connected to the watch ear at the other end of the host through the watch grain structure 100. The user only needs to operate the watch grain structure 100 to make the watch band 200 in an annular extension state, and the user's hand is worn in the watch band 200, so that the smart watch can be worn on the wrist position. By further operating the watch grain structure 100, specifically synchronously pressing and rotating the elastic knob, the length of the watch band 200 can be accurately adjusted according to the user's comfort to tighten the watch band 200 and complete the wearing step.

[0072] The embodiment sets the watch grain structure 100 adjacent to the host, which is connected and matched with the host, so that the watch band 200 can be in an integrated structure, without intentionally setting the watch band 200 as two, thereby effectively avoiding the wearing step by disassembling the conventional watch buckle. The scheme of the embodiment makes the watch band 200 more beautiful, more convenient to operate and stronger in stability, greatly improving the user's experience. Of course, in the embodiment, the watch band 200 can also be selected as a split type structure, that is, the conventional watch buckle is selected between the two watch bands 200, and the watch grain structure 100 provided in the embodiment is selected between one of the watch bands 200 and the host. This can greatly enrich the application scenarios of the smart watch and meet the use requirements of more users, without specific limitation, and any structure change is within the protection scope of the patent.

[0073] In order to make the watch grain structure 100 completely connect to the contour structure of the host and the watch band 200, refer to Figure 1 and Figure 2Since the width of the host is greater than the width of the watch band 200, the shell 1 of the watch grain structure 100 can be preferably set in an isosceles trapezoidal block structure to match the profiles of the host and the watch band 200, so that the overall aesthetic degree is higher. Of course, based on the different sizes of different models of smart watches, the specific structure of the shell 1 can be flexibly set according to the actual product, and is not limited to the isosceles trapezoidal block structure.

[0074] Further, in the embodiment, continuing to refer to Figure 1 and Figure 2 , the shell 1 away from the watch band connecting piece 25 side is provided with a host connecting grain 12 connected to the host. The host connecting grain 12 is used to dock the watch ear of the host, and the watch band connecting piece 25 is used to dock the end of the watch band 200, so that the assembly between the watch grain structure 100, the host and the watch band 200 can be completed. The specific structure of the watch band connecting piece 25 and the host connecting grain 12 is not specifically limited here, and can be flexibly set according to the profiles of the watch band 200 and the host, which is within the protection scope of the patent, and will not be described in detail here.

[0075] It is worth mentioning that in the embodiment, the host connecting grain 12 can be preferably integrally formed with the shell 1, so that the structural strength of the docking between the host and the watch grain structure 100 can be greatly improved. For example, the shell 1 and the host connecting grain 12 can be formed by plastic injection molding or metal liquid cooling molding, which is within the protection scope of the patent and is not specifically limited here.

[0076] In the embodiment, referring to Figure 3 and Figure 4 , by setting the elastic knob in a structure of pressing first and then rotating, it can be effectively avoided that the user easily rotates the elastic knob due to accidental touch or external force during the user's daily wearing of the smart watch, so that the size length of the watch band 200 is slightly changed to affect the user's wearing experience. Through the structure of the embodiment, the elastic knob is always in the state of being popped up during the user's daily work and life, at this time the gear 23 releases the limiting of the elastic buckle 24, so that the elastic buckle 24 is in the state of being automatically popped up upward to be buckled and matched with the corresponding slot 2513 above, so as to limit the rotation of the gear 23. In this way, the elastic knob cannot be rotated, and the gear 23 and the rack 2512 are still in the state of engagement at this time, so that the length of the watch band 200 can be locked, and even if the user wears the smart watch for a long time, the very comfortable wearing experience can be ensured during the wearing process.

[0077] Wherein, several slot positions 2513 are selectively matched with the elastic buckle position 24, so that when the watchband 200 is adjusted to the best comfortable size during the process of pressing and rotating the elastic knob to adjust the length of the watchband 200, the user can immediately stop rotating the elastic knob and release the pressing force on the elastic knob, so that the elastic knob automatically rebounds. At this time, the elastic buckle position 24 will automatically pop up to be clamped inside the corresponding slot position 2513, so that the gear 23 cannot be rotated due to limitation, so as to form the locking of the watchband 200. Of course, if the user needs to loosen or tighten the watchband 200, it only needs to repeat the above steps to seek the best wearing size by selecting different slot positions 2513 to match the elastic buckle position 24. The rotation range of the elastic knob is limited by the travel station 2511, which can effectively ensure that the watchband connector 25 will not be separated from the shell 1.

[0078] It is worth mentioning that in the embodiment, the travel range of the watchband 200 can be flexibly set according to the actual application scene, and the stretching amplitude of the watchband 200 can be changed by changing the length of the rack 2512 and the travel range of the travel station 2511, which is not limited here.

[0079] In the embodiment, referring to Figures 2 to 4 , the elastic knob can be preferably arranged at the upper position of the shell 1. Such a position setting can make the elastic knob outwardly arranged when the user wears the smart watch, so as to be opposite to the user, which is convenient for the user to quickly operate.

[0080] Specifically, the elastic knob can include a knob body 21 and an elastic member 22. A rotating station 13 for accommodating the knob body 21 can be preferably arranged at the middle position of the upper end of the shell 1. The specific structure of the rotating station 13 can not be limited in the embodiment, and only needs to ensure that the knob body 21 can be circumferentially rotated and longitudinally moved therearound, and any structure is within the protection scope of the patent. For example, referring to Figure 3 and Figure 4 , the rotating station 13 can be a ring table structure protruding from the upper end surface of the shell 1, and the lower part of the knob body 21 is provided with a ring groove structure for rotating cooperation with the ring table structure. The ring table structure can form a guide and limit for the knob body 21, and the user only needs to exert a force in the clockwise or counterclockwise direction of the knob body 21, and the knob body 21 can be rotated around the rotating station 13 under the guidance of the ring table structure.

[0081] Further, the elastic member 22 can be a pressing spring, but is not limited thereto. The pressing spring is installed inside the rotating station 13 and is used to abut against the knob body 21. In order to effectively ensure that the pressing spring does not twist and deform along with the knob body 21 during rotation of the knob body 21, or interferes with normal rotation of the knob body 21, a ring-shaped rotating ring can be arranged at the position of the bottom of the knob body 21 used to abut against the pressing spring. The ring-shaped rotating ring is used to abut against the pressing spring, so that the ring-shaped rotating ring does not rotate along with the knob body 21 under the action of the pressing spring during rotation of the knob body 21. This can effectively prevent the pressing spring from restricting free rotation of the knob body 21, thereby greatly improving the operation feeling of the user during rotation of the knob body 21.

[0082] When the user removes the pressing force applied to the knob body 21, the pressing spring is used to provide a force for upward rebounding of the knob body 21, to drive the gear 23 to move upward, so that the elastic buckle 24 automatically rebounds to be buckled and matched with the slot 2513 above it, thereby restricting rotation of the gear 23, to form locking of the watchband 200.

[0083] As a preferred scheme of the present embodiment, the knob body 21 can be in a disc structure, and the exposed peripheral edge of the knob body 21 in the rotating station 13 is provided with anti-skid lines. The user only needs to pinch the peripheral edge of the knob body 21, and the knob body 21 can be driven to rotate clockwise or counterclockwise under the friction of the anti-skid lines. The anti-skid lines can effectively prevent slippage during rotation, thereby greatly improving the operation experience of the user. Of course, the present embodiment can not make any limitation on the specific structure and design of the anti-skid lines, and the anti-skid lines can be flexibly set according to actual use requirements, which is not limited herein.

[0084] Further, in the present embodiment, referring to Figure 3 and Figure 4, the center position of the rotating station 13 is provided with a hole position 14 communicated with the slide 11. As a preferred scheme of the embodiment, the gear 23 specifically can include a gear body 231 and a gear shaft 232, the gear shaft 232 is installed at the center position of the gear body 231, and the gear shaft 232 extends to the rotating station 13 through the hole position 14, used to butt the knob body 21, so as to fix the gear body 231 inside the slide 11, specifically fix the gear body 231 inside the stroke station 2511, so that the gear body 231 is engaged with the rack 2512. Wherein, preferably, a threaded hole 2321 is arranged at the free end of the gear shaft 232, and by arranging a mounting hole 211 corresponding to the threaded hole 2321 at the center position of the knob body 21, a screw 233 can be arranged to pass through the mounting hole 211 from the upper position of the knob body 21, and be screwed with the threaded hole 2321, so as to finally form the assembly of the gear 23 and the knob body 21. Of course, the gear 23 and the knob body 21 can also be assembled in one body by other ways, which are not limited here, and any assembly form is within the protection scope of the patent.

[0085] It is worth mentioning that, in the embodiment, referring to Figure 3 and Figure 4 , preferably, a decorative cover 212 is arranged at the position of the knob body 21 corresponding to the upper position of the mounting hole 211. The decorative cover 212 can cover the head of the screw 233 on the one hand, so as to achieve the effect of beauty, and on the other hand, can effectively isolate the impurities and dirt from the outside into the mounting hole 211, so as to cause corrosion of the screw 233.

[0086] In the embodiment, referring to Figures 2 to 5 , the watchband connecting piece 25 can include a sliding block 251 slidingly arranged in the slide 11 and a watchband connecting particle 252 arranged at the end of the sliding block 251. The watchband connecting particle 252 is slidingly connected to the slide 11 through the sliding block 251. As a preferred, the sliding block 251 can be integrally formed with the watchband connecting particle 252, but is not limited to this. The profile of the sliding block 251 is matched with the slide 11, and the sliding block 251 is used to slidingly cooperate with the slide 11 in the movement process of the watchband connecting particle 252, so as to ensure that the watchband connecting particle 252 can move smoothly and will not easily move, and can greatly improve the structural strength in the adjustment process.

[0087] In the embodiment, the specific structure of the sliding block 251, the watchband connecting particle 252 and the main machine connecting particle 12 can not be limited too much here, and can be flexibly set according to the profile of the watchband 200 and the main machine, which are within the protection scope of the patent, and will not be described too much here.

[0088] As a preferred, referring to Figure 3 and Figure 5In order to further ensure that the watchband 200 is more flexible and stable during the extension and contraction, and does not affect the actual experience of the user due to the strong shock, preferably, a damping member 26 is arranged between the slider 251 of the watchband connecting member 25 and the shell 1, which is used to offset or alleviate the shock generated during the sliding of the slider 251. Specifically, the damping member 26 can include a guide rod 261 and a telescopic spring 262. Preferably, a guide rod 261 is arranged on each side edge of the end of the slider 251 away from the watchband connecting member 252, and a telescopic spring 262 is arranged on each guide rod 261. In the natural extension state, the length of the telescopic spring 262 is greater than the length of the guide rod 261. Thus, during the sliding of the slider 251 along the slide 11, the part of the telescopic spring 262 extending out of the guide rod 261 abuts against the inner wall of the shell 1, which can effectively alleviate the shock during the sliding of the slider 251, thereby greatly improving the stability of the watchband connecting member 252 during the movement, so that the watchband 200 can be stably extended and shortened. Of course, the damping member 26 can also have other structures, which are within the protection scope of the present patent, and will not be described in detail here.

[0089] In the present embodiment, referring to Figure 2 , the watchband connecting member 252 and the host connecting member 12 are arranged opposite to each other, and the user can make the watchband connecting member 252 move towards or away from the host connecting member 12 by synchronously pressing and rotating the knob body 21, thereby adjusting the length of the watchband 200.

[0090] Further, referring to Figure 3 and Figure 5The stroke station 2511 can be specifically arranged at the middle position of the sliding block 251. As a preferred option, the stroke station 2511 can be a sliding hole 24212 arranged at the middle position of the sliding block 251, which penetrates the wall thickness of the sliding block 251 and has a rectangular hole structure and is arranged along the connecting direction of the watch connection particle 12 and the watchband connection particle 252. Further, the rack 2512 is arranged at the inner side edge of the sliding hole 24212 and is arranged along the connecting direction of the watch connection particle 12 and the watchband connection particle 252. The rack 2512 can be integrally formed with the sliding block 251, which can greatly improve the stability of the rack 2512 during transmission and ensure that the watchband connection particle 252 will not be separated from the sliding hole 24212 due to excessive force during movement. Of course, the rack 2512 can also be arranged at the edge of the sliding hole 24212 by, for example, screws, and the rack 2512 can be replaced in a split structure, which can ensure that the sliding block 251 and the watchband connection particle 252 can be recycled, thereby greatly saving economic costs. The gear 23 is always located inside the sliding hole 24212 to engage with the rack 2512. The elastic knob is synchronously pressed and rotated to drive the gear 23 to move the rack 2512, thereby changing the position of the watchband connection particle 252 relative to the housing 1 to adjust the length of the watchband 200.

[0091] In this embodiment, referring to Figures 5 to 7 The elastic buckle 24 can specifically include a base 241, a cantilever 242, and a reset member 243. The base 241 is fixedly arranged at the bottom position of the slide 11 in the housing 1. The specific structure and fixing method of the base 241 are not limited here and can be flexibly set according to actual use requirements, which are within the protection scope of the present patent. The cantilever 242 is hinged to the base 241 and located below the gear 23 and the sliding block 251 of the watchband connection particle 25. Further, the cantilever 242 is provided with a protrusion 2422, and the reset member 243 is arranged between the cantilever 242 and the base 241. In the natural state, the cantilever 242 is not pressed by the gear 23, and the reset member 243 automatically lifts the cantilever 242 upward, so that the protrusion 2422 is embedded in the corresponding slot 2513, thereby forming a lock for the watchband connection particle 25. In the pressed state, the gear 23 abuts against the end face of the cantilever 242 to drive the cantilever 242 to move downward, so that the protrusion 2422 is separated from the slot 2513. At this time, the user rotates the elastic knob to drive the gear 23 to move the rack 2512, so as to adjust the position of the watchband connection particle 25 relative to the housing 1, thereby enabling the user to seek the best wearing size.

[0092] As a preferred option of the present embodiment, referring to Figure 6 and Figure 7, the cantilever 242 can include two arms 2421 symmetrically hinged to the base 241. Specifically, a mounting lug 2411 extending outwardly is arranged at a middle position of one side of the base 241, the mounting lug 2411 is provided with a rotating shaft 2412, and the two ends of the rotating shaft 2412 extend to the two sides of the mounting lug 2411 respectively. Correspondingly, the end of each of the two arms 2421 is provided with a rotating part 2423, the rotating part 2423 is provided with a through hole, and the two rotating parts 2423 are respectively arranged on the two ends of the rotating shaft 2412 through the through holes, so that the two arms 2421 are symmetrically rotated around the base 241.

[0093] Further, the free end of each of the two arms 2421, that is, the end away from the rotating part 2423, is provided with a sliding seat 24211, and the number of the reset members 243 is two, which are respectively arranged at positions corresponding to the two sliding seats 24211 of the base 241 to be in sliding cooperation with the two sliding seats 24211. As an option, the sliding seat 24211 can be arranged on one side of the end of the arm 2421, and the other side of the arm 2421 corresponding to the sliding seat 24211 is close to each other but not in contact.

[0094] In the embodiment, referring to Figure 6 and Figure 7 , the reset member 243 can include a guide column 2431, a limiting block 2432 and a reset spring 2433, and the sliding seat 24211 is provided with a sliding hole 24212 penetrating the wall thickness thereof. The guide column 2431 slides along the base 241, the reset spring 2433 is sleeved on the guide column 2431, and the free end of the guide column 2431 is arranged in the sliding hole 24212, so that the sliding seat 24211 and the reset spring 2433 are in abutting cooperation, and then the limiting block 2432 is fixed on the free end of the guide column 2431 to fix the sliding seat 24211 on the guide column 2431, so as to ensure that the sliding seat 24211 will not be separated from the free end of the guide column 2431 during the up and down movement of the sliding seat 24211 along the guide column 2431. In the embodiment, the sliding seat 24211 and the base 241 are affected by the reset spring 2433, so that the two arms 2421 are rotated towards the base 241 when the pressure of the gear 23 is applied to the two arms 2421, and the two arms 2421 are automatically rotated upward and rebound when the pressure of the gear 23 is removed. In the embodiment, the limiting block 2432 can be directly formed integrally with the guide column 2431, and the guide column 2431 can be screwed into the base 241 to complete the assembly of the reset member 243 and the base 241, which is not specifically limited herein. Of course, the reset member 243 can also have other structures, which are not limited to this, and can be flexibly set according to actual use requirements, which are all within the protection scope of the patent.

[0095] Further, referring to Figure 6 and Figure 7The convex block 2422 is provided on the two arms 2421, and is preferably provided adjacent to the sliding block 24211, but is not limited thereto. The gear body 231 is provided with an abutting convex block 234 at one end away from the gear shaft 232, which is formed directly below the gear body 231 by the gear shaft 232, and is not specifically limited herein. The abutting convex block 234 abuts the position where the two arms 2421 are close to each other in the pressed state, to drive the two arms 2421 to move downward synchronously, so that the convex block 2422 is separated from the groove 2513. At this time, the user can rotate the elastic knob to drive the gear 23 to move the rack 2512, so as to adjust the position of the watchband connecting piece 25 relative to the housing 1.

[0096] In this embodiment, as a preferred solution, referring to Figure 5 and Figure 8 , the plurality of groove positions 2513 can include two rows of groove positions 2513, which are respectively provided on the opposite sides of the stroke station 2511 and correspond to the two convex blocks 2422. Among them, the plurality of groove positions 2513 in one row of groove positions 2513 and the plurality of groove positions 2513 in the other row of groove positions 2513 are staggered one by one, and the two rows of groove positions 2513 are respectively used to be engaged with the two convex blocks 2422 during the movement of the rack 2512 driven by the gear 23.

[0097] As a preferred solution of this embodiment, referring to Figure 8 , one row of groove positions 2513 on one side of the stroke station 2511 includes three groove positions 2513, and one row of groove positions 2513 on the other side of the stroke station 2511 includes two groove positions 2513. Among them, the two rows of groove positions 2513 are staggered one by one to form five gears, which are 0-4 gears. Among them, 0 gear, 2 gear and 4 gear are located on one side of the stroke station 2511, 1 gear and 3 gear are located on the other side of the stroke station 2511, and the distance between each gear is preferably 1 millimeter, but is not limited thereto. During the process of switching the elastic knob from the pressed state to the natural state, the five gears are selectively engaged with the two convex blocks 2422 to adjust the length of the watchband 200.

[0098] Specifically, the two protrusions 2422 are symmetrically arranged on the two arms 2421, one of which is sequentially engaged with the 0th, 2nd and 4th gears during the rotation of the knob body 21, and the other is sequentially engaged with the 1st and 3rd gears during the rotation of the knob body 21, so as to form the length adjustment of the five gears of the watchband 200. It is worth mentioning that, for example, when one of the protrusions 2422 is engaged with the 0th gear, the other protrusion 2422 is located between the 0th and 1st gears. That is to say, only one of the two protrusions 2422 is engaged with the gears, and the other protrusion 2422 is located between two adjacent gears. In this embodiment, in order to effectively avoid the interference of the protrusion 2422 located between two adjacent gears on the other protrusion 2422, the two protrusions 2422 are preferably elastically arranged on the upper end surface of the arm 2421. For example, a groove corresponding to the position of the protrusion 2422 can be arranged on the upper end surface of the arm 2421 to accommodate the protrusion 2422, and a spring is arranged at the bottom of the groove to connect the protrusion 2422, so that the protrusion 2422 can retract into the groove when subjected to external force and automatically rebound when the external force is removed. In this way, when the protrusion 2422 on one arm 2421 is engaged in one groove 2513 on one side of the travel gear 2511, the protrusion 2422 on the other arm 2421 rebounds towards the arm 2421 under the abutment of the bottom wall of the watchband connecting piece 25, so as to ensure that the watchband 200 can be adjusted in five gears under the rotation of the knob body 21. The user only needs to rotate the knob body 21 counterclockwise to drive the gear 23 to rotate the rack 2512, so as to adjust the elongation of the watchband 200. The watchband 200 contraction adjustment steps are the same as above, and the watchband 200 can be contracted by rotating the knob body 21 clockwise. Of course, in this embodiment, the gears are not limited to five gears, and the number of gears can be flexibly set according to actual use requirements, which is within the protection scope of the present application, and will not be described in detail here.

[0099] Of course, in this embodiment, referring to Figure 3 and Figure 4 , the bottom of the shell 1 is also detachably provided with a bottom cover 15. The staff can quickly disassemble, maintain and clean the various parts inside the shell 1 by disassembling the bottom cover 15 from the shell 1, so as to greatly reduce the difficulty of maintaining the watch structure 100.

[0100] It should be noted that the above embodiments can be freely combined as needed. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
