Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

In this application, unless expressly stated or limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can include, for example, fixed connections, removable connections, or integral parts; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise.

In the description of the present application, it is to be understood that the terms "inner", "outer", "upper", "bottom", "front", "rear", and the like, when used, refer to an orientation or positional relationship, if any, shown in the drawings, that is solely for the purpose of facilitating the description and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be considered as limiting the present application.

Watches or clocks are not uncommon in daily life as timepieces. At present, with the popularization of a built-in electronic timer in an intelligent mobile terminal, a watch gradually becomes a high-end ornament, and the watch can play a role in timing on one hand and can play a role in personalized decoration on the other hand; therefore, the method becomes more and more choices when people decorate the individuality.

Of course, watches, in addition to being decorative and commonly used for timekeeping, also have functional requirements, such as the display of calendars, weeks, etc. Generally, a wristwatch includes a watch body and a band; the watchband is connected with the watch body; the band is used to hold the watch body on the user's wrist to function as a device and also to facilitate the user's observation of time.

The watch body will typically include a case and a watch movement disposed within the case. It is understood that the watch core may be an electronic timing watch core, for example, the watch core is integrated on an integrated circuit board (PCB) or a Printed Circuit Board (PCB) through a single chip microcomputer and a timer, and a power source (e.g., a rechargeable battery, a button battery, etc.) is disposed in the case, so as to achieve timing. The electronic watch core can be internally provided with a liquid crystal display screen in the shell, the liquid crystal display screen is in electric signal connection with the integrated circuit board or the PCB, and the time is displayed through the liquid crystal display screen. Of course, a driving motor (such as a servo motor, a synchronous motor or a stepping motor) may be arranged in the housing, and the pointer system is connected to an output shaft of the driving motor, and the driving motor is in electrical signal connection with the integrated circuit board or the PCB; the pointer system is driven to rotate by the driving motor, so that the time indication is realized.

Alternatively, the movement may be a mechanical movement, for example by winding a spring, and then driving the hands system in rotation by gradually releasing the energy accumulated in the winding, so as to obtain the time indication.

In some possible ways, the energy source of the rechargeable battery can be derived from the charging of the charger, the collection and conversion of solar energy by the dial, and even a swinging piece is arranged in the shell and used for collecting and converting mechanical energy of the watch during the moving or vibrating process; of course, other modes are possible, and this is not listed in the embodiments of the present application.

In some possible ways, a user may often use a watch across regions or time zones; that is, the user may often need to time-tune the watch. In order to facilitate user tuning, in this embodiment of the application, a control chip may be further disposed in the casing, for example, a Central Processing Unit (CPU), a Micro Control Unit (MCU), a Neural Network processor (Neural Network Processing Unit), or the like is disposed; when a user times through the time-adjusting handle or the time-adjusting button, the control chip can control the rotation of the pointer system according to the requirement, so that the time adjustment of the user is facilitated.

The watch may also require some special functions for timing after the basic timing function is satisfied. For example, in a diving scene, a downhole operation, a fire fighting or disaster relief work scene, it is generally necessary for the worker to wear an oxygen cylinder. As is known, the oxygen cylinders are limited in their capacity to contain oxygen, and are generally only capable of sustaining normal breathing for a few minutes to tens of minutes in an adult. For example, an air respirator with a pressure of 25MPa generally maintains normal breathing of an adult for 20-25 min, and the time for maintaining the operation state is shorter. There is a need for a timing device that can accurately time the operation time.

Although the ordinary watch can play a role of timing, the ordinary watch is obviously not suitable for the operation scene. The reason is that, assuming that the current time is 17:36, the hands of the watch indicate time is 5: 36; the working time is 15 minutes, that is, when the hands of the wristwatch indicate 5:51, the worker must leave the work site to avoid a dangerous situation. However, during the work, the operator obviously has no extra time to calculate the time indicated by the hands of the wristwatch, and the observation is also prone to error. This easily results in the worker missing the optimum evacuation time and thus creating a dangerous situation.

In order to facilitate the convenience of timing and observing time for operators, a front ring is arranged on a shell of the watch in the related art, and scales or numbers for marking time are arranged on the front ring. The front ring is coaxially and rotatably connected with the shell. And, set up a top post in the lower side of the front ring, set up the lower surface of the front ring as the rough ratchet surface usually, set up a spring on the top post, the spring is abutted with body, like this, when turning the front ring towards a certain direction, the top post compresses the spring, and after confirming the position of the front ring (for example, aligning the zero point position with minute hand of the pointer), the spring resumes deformation, the bottom surface of the top post abutment in the front ring, in this way can avoid the front ring to turn over.

That is, by setting a zero point on the front ring and adjusting the zero point to be aligned with the minute hand of the indicating hand; thus, when the minute hand is rotated by a certain angle, the elapsed time can be directly read by the reading on the front ring.

Still taking the above-mentioned operation scenario as an example, when the operator needs diving or downhole operation, the length of time that can be operated can be determined according to the pressure of the oxygen cylinder, and the zero point of the front ring is rotated to be aligned with the minute hand of the pointer, which is equivalent to performing zero calibration on the minute hand. After the operator starts to work, the current working duration can be directly read from the reading of the front ring, so that the operator can leave the working site at any time. Thus, the timing during operation is convenient. Of course, the job scenario is merely illustrative. The front circle may also be used for timing in other non-job scenarios (e.g., answering timing).

The current front circle can facilitate the timing of the operator in the operation scene. However, in the operation scene, various emergencies are usually encountered, and the front ring may be rotated by mistake, which may cause inaccurate timing.

In view of the foregoing problem, according to a first aspect of the present application, referring to fig. 1 and fig. 2, fig. 1 is a schematic view of an overall structure of a front ring lock watch case provided by an embodiment of the present application, and fig. 2 is a sectional view taken along a line a-a in fig. 1. The embodiment of the application provides a front ring locking watchcase, includes:

a body 100, the body 100 having a first end face 101 for viewing time.

It will be appreciated that the watch is usually worn on the wrist, the first end surface 101 may be the surface away from the wrist after being worn by the user, and usually, a watch glass 102 is disposed on the surface, and the watch glass 102 may be made of transparent or translucent material, such as common plastic glasses, organic glass, quartz glass or sapphire glass.

Optionally, as shown in fig. 2, the body 100 may further include a middle frame 103, a rear ring 104, and a rear cover 105.

The cover glass 102 may be fixed to the middle frame 103 by bonding, welding, or fitting. The material of the middle frame 103 can be stainless steel, gold-plated, silver-plated or copper-plated frame body; of course, in some possible ways, the middle frame 103 may also be a hard plastic. A rear ring 104 is fixed to an end of the middle frame 103 facing away from the watch glass 102, and the rear ring 104 may be used to fixedly mount a rear cover 105.

Alternatively, the watch glass 102, the middle frame 103, the rear ring 104, and the rear cover 105 may be joined in a sealed manner. For example, the connection may be made by means of a sealant, a gasket, a sealing washer, or the like. Thus, the water-proof device can play an effective water-proof effect when diving.

It is understood that in the embodiment of the present application, the sealing grade may be different according to the waterproof grade. In the embodiments of the present application, this is not limited.

And the front ring 200 is arranged on the body 100 and is positioned at the first end face 101, and the front ring 200 is coaxially and rotatably connected with the body 100. Specifically, as shown in fig. 2, a bead may be disposed on a side wall of the first end surface 101 of the body 100, and a bead may also be disposed on an inner side wall of the front ring 200, and the front ring 200 is coaxially and rotatably connected to the body 100 through the bead.

Alternatively, the bead may be a protruding edge protruding from the side wall of the first end surface 101 of the body 100, a groove is formed between the protruding edge and the side wall of the body 100, and the bead on the inner side wall of the front ring 200 is embedded in the groove and slidably connected with the groove. Thus, the front ring 200 can be coaxially and rotatably connected with the body 100.

In some possible ways, to facilitate the assembly of the front ring 200, the upper surface of the bead on the body 100 may be set as an inclined plane, and the lower surface of the bead on the inner side wall of the front ring 200 may also be set as an inclined plane, so that the front ring 200 may be directly pressed at the first end surface 101 of the body 100 during the assembly.

The front circle 200 is used to cooperate with the watch hands to achieve time period timing.

Specifically, as shown in fig. 1, a metering scale, a number, or a combination of a scale and a number may be provided on an end face of the front ring 200 (specifically, an end face facing the same direction as the first end face 101). The skate can be provided with a zero mark on the end surface of the front ring 200. When the rotary type three-dimensional pointer is used specifically, the front ring can be rotated, and the zero mark is aligned to the minute hand, so that the elapsed time length can be directly read according to numbers or scales after the minute hand rotates for a certain angle, and addition and subtraction calculation is not needed.

Alternatively, the scale, the number, or a combination of the scale and the number may be provided on the end surface of the front ring 200 in the form of an enamel, an imprint, or a stamp.

In some possible examples, in order to improve the overall texture or aesthetic appearance of the watch, as shown in fig. 1, decorative lines or textures may be engraved on the end surface of the front ring 200, so as to improve the hand feeling and aesthetic feeling of the front ring 200.

It can be understood that, because the front ring 200 can axially rotate relative to the body 100, in order to facilitate the rotation of the front ring 200, the situation of difficult rotation or slipping is avoided; in the embodiment of the present application, a plurality of protruding ridges, protruding points, frosted surfaces or friction surfaces, etc. may be further disposed on the outer side wall of the front ring 200. This increases the friction between the front ring 200 and the hand, facilitating the rotation of the front ring 200.

The bottom surface of the front ring 200 has a plurality of positioning portions 201, and the plurality of positioning portions 201 are arranged along the circumferential direction of the front ring 200.

Specifically, the positioning portion 201 may be in the form of a groove recessed from the ground surface of the front ring 200 or a ring gear or the like.

The stopping component 300 is arranged on the body 100 and movably connected with the body 100, and the stopping component 300 is positioned on one side of the front ring 200; the top end of the stopper assembly 300 abuts against the positioning portion 201 to position the front ring 200.

Specifically, referring to fig. 2, the stopper member 300 may be located on one side of the bottom surface of the front ring 200. In a specific design or implementation, the body 100 may be provided with a pin hole, and the stop assembly 300 may be a pin shaft, which is inserted into the pin hole and is movable in the axial direction of the pin hole (for example, the pin shaft is pushed to move by an elastic restoring member such as a silicone pad or a sponge block). Thus, when the front ring 200 rotates, the bottom surface of the front ring 200 pushes the pin to move downward, so that the front ring 200 can rotate, and the front ring 200 rotates through a certain angle (for example, an angle between adjacent positioning portions 201); the pin shaft is pushed by elastic restoring pieces such as a silica gel pad and a sponge block and is sunk into the positioning part 201, so that the front ring 200 is positioned.

It is understood that in the embodiments of the present application, the top end of the pin may be a dome surface or a top surface with a chamfer or a fillet. Thus, when the front ring 200 is rotated next time, the top end of the pin shaft can be smoothly moved out from the positioning portion 201.

A locking member 400 disposed on the body 100 and movably connected to the body 100, wherein the locking member 400 is located at an end of the stopping assembly 300 facing away from the front ring 200; retaining member 400 is adapted to operably abut the bottom end of stop assembly 300 such that the top end of stop assembly 300 limits the rotation of front ring 200.

Specifically, referring to FIG. 2, in the embodiment of the present application, a retaining member 400 can be disposed at an end of the stopping member 300 away from the front ring 200, and the retaining member 400 can be operably abutted against a bottom end of the stopping member 300, so that the retaining member 400 can limit the movement of the stopping member 300. So that the stopper assembly 300 cannot be moved downward any more. Thus, when the front ring 200 is erroneously bumped, the rotation does not occur. That is, the front ring 200 will not change after the zero point calibration, so that the timing accuracy of the front ring 200 can be ensured.

In some possible examples, retaining member 400 may be pivotally connected to body 100; the locker 400 may be a swing arm disposed on the body 100, and the swing arm is pushed to abut against the bottom end of the stopping assembly 300 or move away from the bottom end of the stopping assembly 300.

In other possible examples, the locking member 400 may also be a gear rotatably connected to the body 100, wherein the gear is rotated to abut against the bottom end of the stopping member 300 or to be away from the bottom end of the stopping member 300.

It is understood that the retaining member 400 may also be in the form of a pull-out spring, for example, and when it needs to abut against the bottom end of the stop assembly 300, i.e. after the front ring 200 performs zero calibration on the split needle, the spring can be pushed in for abutting limitation. And when the front ring 200 needs to be adjusted, the elastic sheet can be pulled out.

In the embodiment of the present application, by disposing the retaining member 400 on the housing 100 and disposing the retaining member 400 at the end of the stopping assembly 300 away from the front ring 200, after the front ring 200 performs time zero calibration, the retaining member 400 abuts against the bottom end of the stopping assembly 300, so that the top end of the stopping assembly 300 abuts against the positioning portion 201; thus, the position of the front ring 200 can be fixed and the front ring does not rotate due to an erroneous operation or a touch. The timing accuracy of the front circle 200 can be ensured.

Optionally, referring to fig. 3, fig. 3 is a schematic view of the whole structure of the front ring locked watchcase provided by the embodiment of the present application with the front ring removed. The outer side wall of the body 100 is provided with a containing cavity 106, and the locking member 400 is movably installed in the containing cavity 106; the bottom end of stop assembly 300 extends into receiving cavity 106.

Specifically, in the embodiment of the present application, the receiving cavity 106 may be integrally formed with the body 100. Specifically, the frame may be integrally formed with the middle frame 103. Alternatively, the receiving cavity 106 may be formed on the middle frame 103 by a secondary drilling process. The embodiment of the present application does not limit this.

Alternatively, the housing 106 may be a recess formed along a side wall of the side of the middle frame 103 (for example, as shown in fig. 3), and the recess may be located on a side wall of the side facing away from the watch where the timing handle is provided.

In some possible ways, the receiving cavity 106 may also be a notch formed directly below the stopper assembly 300. For example, in the case that the locker 400 is a gear or a resilient plate, the locker 400 may be disposed in the slot.

Further, with continued reference to FIG. 3, retaining member 400 includes a first portion 401 and a second portion 402; the first end 4011 of the first portion 401 is hingedly connected to the body 100. Specifically, a shaft hole is formed in the middle frame 103, a shaft rod is arranged at the first end 4011, and the shaft rod is inserted into the shaft hole, so that the hinge joint is realized; or, the first end 4011 is also provided with a shaft hole, and the shaft rod is sequentially inserted into the two shaft holes, so that the hinge joint is realized.

In some possible ways, the shaft may be disposed on the middle frame 103, and the first end 4011 may be provided with a shaft hole.

Second portion 402 is disposed on first portion 401 with second portion 402 being located between first portion 401 and body 100, second portion 402 abutting the bottom end of stop assembly 300.

Specifically, referring to fig. 3, the second portion 402 may be disposed on a side wall of the first portion 401 near the side of the body 100. After the first portion 401 is received in the receiving cavity 106, the second portion 402 is located below the stopper member 300, and thus abuts against the bottom end of the stopper member 300.

In one particular example, second portion 402 can be located directly below stop assembly 300.

It will be appreciated that the second portion 402 may also be located laterally below the stop assembly 300, for example, a lateral stop wall may be provided at the bottom end of the stop assembly 300, and the second portion 402 may also abut against the lateral stop wall.

Alternatively, retaining member 400 may be an integrally formed structure in the present embodiment; or in some possible ways retaining member 400 may be formed by lathing.

It will be readily appreciated that, in order to ensure the aesthetic appearance of the watch, in the embodiments of the present application, the shape of the first portion 401 may be adapted or matched to the shape of the side wall of the body 100, for example, in the arcuate configuration shown in fig. 3.

It can be understood that when the front ring 200 needs to be rotated to zero the minute hand of the watch; it is desirable to have second portion 402 clear of, i.e., no longer abut, the bottom end of stop assembly 300. This requires that the first portion 401 be pulled out of the accommodating cavity 106, and in order to facilitate the pulling out of the first portion 401 from the accommodating cavity 106, referring to fig. 1 and 3, in the embodiment of the present application, a third portion 403 is further provided at the second end 4012 of the first portion 401; the third portion 403 protrudes from the accommodating cavity 106.

In this way, the first part 401 and the second part 402 can be easily pulled out of the accommodating cavity 106 through the third part 403, and the front ring 200 can be rotated and adjusted again.

It is understood that, in some possible examples, a poke plate (not shown) may be provided at the hinge point of the first end 4011 and the body 100, and the rotating shaft and the first portion 401 are moved away from the receiving cavity 106 by poking the poke plate. In this case, the shaft may be affixed to the first end 4011.

Further, since the second portion 402 needs to abut against the bottom end of the stopping assembly 300, the second portion 402 can be easily and smoothly inserted into the bottom end of the stopping assembly 300. With continued reference to fig. 3, in the present embodiment, a guide surface 4021 is provided at an edge of the second portion 402, and the guide surface 4021 is used to smoothly transition the bottom end of the stop assembly 300 to the second portion 402.

Specifically, in the embodiment of the present application, the guide surface 4021 may be an inclined surface formed by chamfering; in some possible ways, the guide surface 4021 may be a circular arc surface formed by a round corner.

It is understood that in the present embodiment, the bottom end of the stopper assembly 300 may be provided in the form of a dome, a rounded corner, or a chamfer. In this way, smooth insertion of the second portion 402 into the bottom end of the stop assembly 300 can be further ensured.

It should be noted that after retaining member 400 is received in receiving cavity 106, that is, second portion 402 abuts against the bottom of stop member 300; this can limit the position of the front ring 200 and prevent the front ring 200 from rotating due to erroneous contact. However, it is desirable to avoid the retaining member 400 from popping or falling out of the receiving cavity 106 and failing to lock the front ring 200. In order to avoid this, in the embodiment of the present application, bumps (not shown) are provided on the upper and lower surfaces of the second end 4012, and the bumps may be dots protruding from the upper and lower surfaces of the second end 4012 and may be integrally formed with the second end 4012. Thus, after the retaining member 400 is received in the receiving cavity 106, the protruding point of the second end 4012 and the inner wall of the receiving cavity 106 generate a large friction force, so that the retaining member 400 can be prevented from being disengaged.

In some possible examples, a silicone layer may be covered on the surface of the second end 4012, and the occurrence of the situation that the locking member 400 is released can also be effectively avoided by generating a friction force between the silicone layer and the inner wall of the accommodating cavity 106.

In other possible examples, a magnetic member (e.g., an iron block or a magnet) may be further disposed on the inner sidewall of the accommodating chamber 106; a magnetic member is also disposed at the second end 4012, and the two magnetic members may be oppositely disposed. Thus, the attraction force of the two magnets can be used to prevent the locking member 400 from being removed.

In a specific example, referring to fig. 4, fig. 4 is a partial enlarged view at B in fig. 2. In the embodiment of the present application, the body 100 is provided with the first channel 107 along the axial direction, and the stop assembly 300 includes a stop member 301 and a reset member 302; the first channel 107 is located on one side of the front ring 200, the stop member 301 is inserted in the first channel 107, the reset member 302 is arranged in the first channel 107, one end of the reset member 302 is connected with the stop member 301, the other end of the reset member 302 is connected with the inner wall of the first channel 107, and the reset member 302 is used for pushing the stop member 301 so that the top end of the stop member 301 abuts against the positioning portion 201.

Alternatively, in the present embodiment, the first passage 107 may be a counterbore as shown in fig. 4. The reset 302 may be a spring, one end of which connected to the first channel 107 abuts at a transition step of the counterbore.

In other possible ways, the restoring member 302 may also be two magnets, one of which is disposed on the inner wall of the first passage 107; another magnet is provided on the stopper 301. The stopper 301 may be reset by using an attractive force or a repulsive force of the magnet.

Further, referring to fig. 5 and fig. 6, fig. 5 is a schematic structural view of a front ring locking watchcase provided by an embodiment of the present application, and fig. 6 is a schematic structural view of a stopper of the front ring locking watchcase provided by the embodiment of the present application. In the embodiment of the application, the stopper comprises a first stopper section 3011, a positioning section 3012 and a second stopper section 3013, and the first stopper section 3011 is connected to the second stopper section 3013 through the positioning section 3012; the first stopping section 3011 abuts against the positioning portion 201, the positioning section 3012 is connected with the reset piece 302, and the second stopping section 3013 abuts against the locking piece 400.

Optionally, the positioning portion 201 includes a ratchet, the end of the first stopping section 3011 is a slope, and the slope direction of the slope is the same as the slope direction of the ratchet.

It is understood that the positioning portion 201 may also be the aforementioned groove formed by recessing from the bottom surface of the front ring 200, and the groove may be a circular groove, a polygonal groove or an elliptical groove; the end of the first stop segment 3011 may be a dome surface or a circular arc surface; thus, the front ring 200 can be rotated in both directions.

Alternatively, referring to fig. 7, fig. 7 is another structural schematic diagram of a stopper for locking a watch case by a front ring according to an embodiment of the present application. In the embodiment of the present application, a positioning groove 3013a is concavely formed on the peripheral wall of the second stopping section 3013, and the locking member 400 is inserted into the positioning groove 3013 a.

Thus, the overall length of the stopper 301 can be increased, and the stability of the movement of the stopper 301 on the body 100 can be ensured.

Wherein, the edge of the positioning slot 3013a may be rounded, chamfered, etc.

According to a second aspect of the present application, there is provided a wristwatch comprising a bezel lock case 10 as provided in any of the alternative embodiments of the first aspect of the present application.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
