Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of smart watches, in particular to a detachable main structure part capable of turning over and rotating 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 life and perception. Wearable devices are not only a kind of hardware device, but also realize their powerful functions through software support and data interaction and cloud interaction. Their application fields are very wide, such as medical treatment, fitness and communication, etc. For example, watches have not only been limited to functions such as 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 an extension and expansion of the function of the mobile phone, which brings great convenience to people's daily life.

[0003] Some smart watches on the market have a turning or rotating structure, and the main machine can rotate relative to the base to change the orientation of the main machine screen and camera, which is convenient for users to view information, video calls and take pictures, etc. In general, the main machine cannot be separated from the base, that is, the main machine always moves with the user's wrist and cannot be detached for separate use. The defect brought by this is that the wrist limits the various application scenarios of the main machine, which cannot meet the user's demand for multi-scene use as a mobile phone, such as taking pictures, shooting and video calling through the main machine alone. And usually a rotating shaft is arranged at the end of the main machine to rotate and cooperate with the base. The defect of this is that the rotating part occupies the design space of the main machine, making the overall volume of the main machine relatively bulky and not simple. And the rotating stroke range of the main machine is limited, which cannot adjust the screen in any direction, greatly limiting the application scenarios of the smart watch.

[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 detachable main structure part capable of turning over and rotating and a smart watch, which can change the orientation of the screen at will without rotating the wrist, so that the screen can enter the user's line of sight. And the main machine is separately assembled on the second supporting plate, avoiding the direct arrangement of a rotating shaft at the end of the main machine to rotate and cooperate with the base, greatly saving the design space of the main machine, and the main machine can be used alone after being detached, which will not limit the application scenarios of the main machine due to the constraint of the wrist, thereby greatly improving the user's experience.

[0026] The peripheral edge of the clamping block is provided with an annular clamping groove to form a limiting fit with the hole wall of the clamping hole when the clamping block is clamped in the clamping hole.

[0027] In some embodiments, the host computer has a back side opposite to the screen, and is provided with a clearance adjacent to the second end;

[0028] The clearance is used to allow the rotating mechanism to enter the interior of the host computer when the host computer is stacked on the base.

[0029] In some embodiments, the second end of the host computer is provided with an operating portion;

[0030] The operating portion is configured to be forced by the user's hand to adjust the orientation of the screen.

Further, the second supporting plate is arranged on the first supporting plate, and the orientation of the screen of the host relative to the wrist of the user can be further changed by adjusting the inclination angle between the first supporting plate and the second supporting plate, so that the user can ensure that the screen can enter the field of view of the user without rotating the wrist, greatly simplifying the adjustment steps of the screen and improving the use experience of the user. Of course, the host is separately assembled on the second supporting plate, which effectively avoids directly arranging a rotating shaft at the end of the host to rotate with the base, greatly saving the design space of the host. And the host can be used independently in multiple scenes after being detached from the second supporting plate, such as taking pictures, shooting videos, and surfing the Internet, which can greatly expand the application scenarios of the host. Further, when the host is stacked on the base, the first supporting plate and the second supporting plate can be automatically stretched and hidden between the host and the base, without being exposed to the appearance, which can greatly improve the simplicity and compactness of the overall appearance of the host components.

DETAILED DESCRIPTION

[0052] 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 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.

[0053] In order to make the drawing simple, only the parts related to the application are shown in each drawing, which does not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components 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.

[0054] It should be further understood that the term "and / or" used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0055] It should be noted that in this document, unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of 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.

[0056] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0057] According to one specific embodiment of the present application, as Figures 1 to 8As shown, the present application provides a detachable main body component 100 for realizing flipping and rotating, which can specifically include a base 1, a main body 2, a rotating mechanism 3, a first supporting plate 4 and a second supporting plate 5. The first supporting plate 4 is installed on the base 1 through the rotating mechanism 3. The second supporting plate 5 is rotationally connected to one end of the first supporting plate 4 away from the rotating mechanism 3. The main body 2 is detachably installed on the second supporting plate 5. Among them, the rotating mechanism 3 makes the first supporting plate 4 be operatively flipped and / or rotated relative to the base 1, and the second supporting plate 5 is used to drive the main body 2 to flip around the first supporting plate 4, so that the screen 21 of the main body 2 has different attitudes towards.

[0058] It is worth mentioning that the back of the main body 2 is also provided with a camera relative to the second supporting plate 5, so that when the main body 2 is flipped and rotated relative to the base 1, the camera can move together with the main body 2, so as to facilitate the user to seek the best imaging angle and meet the actual use demand.

[0059] In this embodiment, the rotating mechanism 3 can be used for flipping and / or rotating the first supporting plate 4 relative to the base 1, so that the first supporting plate 4 can drive the second supporting plate 5 and the main body 2 to rotate and / or flip relative to the base 1, so as to change the orientation of the screen 21. Further, the second supporting plate 5 is arranged on the first supporting plate 4, and by adjusting the inclination angle between the first supporting plate 4 and the second supporting plate 5, the orientation of the screen 21 of the main body 2 relative to the user's wrist can be further changed, so that the user can ensure that the screen 21 can enter the user's line of sight without rotating the wrist, greatly simplifying the adjustment steps of the screen 21 and improving the user's experience. Of course, the main body 2 is separately assembled on the second supporting plate 5, which effectively avoids directly arranging a rotating shaft on the end of the main body 2 to rotate with the base 1, greatly saving the design space of the main body 2. And the main body 2 can be used independently after being detached from the second supporting plate 5, like a mobile phone, to meet the needs of multiple scenes, such as taking pictures, shooting videos and surfing the Internet, which can greatly expand the application scenarios of the main body 2. Further, when the main body 2 is stacked on the base 1, the first supporting plate 4 and the second supporting plate 5 can be automatically stretched and hidden between the main body 2 and the base 1, without being exposed to the appearance, which can greatly improve the simplicity and compactness of the overall appearance of the main body component 100.

[0060] Of course, the present application also provides a smart watch in a second aspect, which can specifically include a watchband and the detachable main body component 100 for realizing flipping and rotating provided by the present application in the first aspect. Among them, referring to Figure 1 , the base 1 has oppositely arranged first and second mounting parts 12 and 13, the first mounting part 12 is used for mounting one end of the watchband, and the second mounting part 13 is used for mounting the other end of the watchband.

[0061] It is worth mentioning that the specific style and structure of the watchband is not limited in the embodiment, for example, it can be an elastic strip, and the two ends are respectively installed on the first mounting part 12 and the second mounting part 13. Of course, it can also be a two-strip buckle connection structure, and the two strips are respectively installed on the first mounting part 12 and the second mounting part 13, which is within the protection scope of the patent. Further, the mounting mode of the watchband and the first mounting part 12 and the second mounting part 13 is not limited here, which can be fixedly connected through a rotating shaft, and of course, it can also be fixed by welding or buckling, which is within the protection scope of the patent and is not limited here. It can be flexibly changed according to the user's preference.

[0062] When the user uses the smart watch, the orientation of the screen 21 of the host 2 relative to the base 1 can be adjusted according to the user's habit to change the angle of video and photographing, so as to achieve better call and photographing effect, and at the same time, it can effectively prevent the discomfort of the wrist caused by long video time, and in the process of photographing, the best shooting angle can be obtained without adjusting the angle of the wrist, which provides better use experience for the user in the process of using the smart watch.

[0063] More worth mentioning is that in the embodiment, the host 2 has a first end 22 and a second end 23 opposite to each other, and under the adjustment of the first supporting plate 4 and the second supporting plate 5, the first end 22 of the host 2 is used to abut against the base 1 when the host 2 and the base 1 form an angle, so as to cooperate with the first supporting plate 4 and the second supporting plate 5 to form a support for the host 2, and the second end 23 of the host 2 follows the host 2 to move up to change the orientation of the screen 21 and obtain the best use posture.

[0064] When the host 2 is rotated to the state of being stacked on the base 1, in order to ensure that the host 2 will not automatically turn up from the base 1 under the action of external force, for example, wrist shaking, that is, in order to always maintain the normal use state of the host 2, a buckle can be arranged on the back of the host 2 opposite to the screen 21 and adjacent to the second end 23, and a matched buckle groove can be arranged on the base 1 corresponding to the buckle. In this way, when the host 2 is rotated to the state of being stacked on the base 1, the buckle and the buckle groove are buckled and matched to limit the host 2 from being separated from the base 1. Of course, a buckle can also be arranged on the base 1, and a buckle groove can be arranged on the host 2, or the host 2 and the base 1 can be magnetically attracted by a magnetic attraction member, which can also achieve the same technical effect as described above. That is to say, any structure that can fix the host 2 and the base 1 is within the protection scope of the patent and is not limited here.

[0065] Further, the second end 23 of the host 2 is further provided with an operation part. In the embodiment, the operation part can be formed by directly arranging anti-skid lines on the second end 23 of the host 2, or the operation part can be formed by arranging anti-skid rubber on the second end 23 of the host 2, and no limitation is made herein. At this time, the user only needs to press the operation part and apply a force to the operation part away from the base 1, and when the force is greater than the force of the buckle and the buckle groove, the host 2 can be separated from the base 1, and the angle between the first supporting plate 4 and the second supporting plate 5 can be adjusted flexibly according to the actual use requirement of the user, so that the inclination of the host 2 relative to the base 1 can be adjusted, and the screen 21 can enter the line of sight of the user to obtain the best use posture.

[0066] In the embodiment, when the host 2 is separated from the base 1, the user can directly pinch the opposite two end surfaces of the second end 23 of the host 2 by the hand, and the orientation of the screen 21 of the host 2 can be adjusted arbitrarily. Of course, the adjustment mode of the host 2 can be various, and can be adjusted by the user according to the habit, for example, the user can adjust the host 2 by pinching the opposite two side walls of the host 2, which is within the protection scope of the patent and will not be described in detail herein.

[0067] In the embodiment, the specific structure of the rotating mechanism 3 is not limited, and only needs to ensure that the rotating mechanism 3 can drive the host 2 to rotate and flip synchronously relative to the base 1, and any structure is within the protection scope of the patent.

[0068] Of course, as a preferred scheme of the embodiment, referring to Figures 2 to 8 , the rotating mechanism 3 specifically can include a rotating shaft and a flipping piece 31. Specifically, the middle position of one end of the base 1, that is, when the host 2 is stacked on the base 1, the middle position of the base 1 corresponding to the second end 23 of the host 2 is provided with a rotating support 11 for installing the rotating shaft. And the flipping piece 31 is arranged at the end of the first supporting plate 4 away from the second supporting plate 5, and is arranged in rotating cooperation with the rotating shaft. The rotating shaft can be arranged to rotate the first supporting plate 4 relative to the base 1, and the flipping piece 31 can be arranged to flip the first supporting plate 4 relative to the base 1. Thus, under the synchronous cooperation of the rotating shaft and the flipping piece 31, the first supporting plate 4 can rotate and flip synchronously relative to the base 1, and the screen 21 of the host 2 can have an orientation in any direction.

[0069] As a preferred, the rotating shaft, the rotating support 11 and the base 1 can be directly integrated. Thus, the structural strength of the rotating shaft in the process of acting on the flipping piece 31 can be greatly improved, and the host 2 can be ensured to rotate and flip smoothly relative to the base 1.

[0070] It is worth mentioning that in the embodiment, the connection between the turnover piece 31 and the rotating shaft can be provided with a first damping piece, which is used to fix the turnover piece 31 at any position during the rotation along the rotating shaft. The connection between the turnover piece 31 and the first supporting plate 4 can be provided with a second damping piece, which is used to fix the first supporting plate 4 at any position during the rotation along the turnover piece 31. The connection between the first supporting plate 4 and the second supporting plate 5 can be provided with a third damping piece, which is used to fix the second supporting plate 5 at any position during the rotation along the first supporting plate 4. Of course, the specific structure and damping mode of the first damping piece, the second damping piece and the third damping piece are not limited in the embodiment, and only need to ensure that the three can cooperate together, so that the host 2 can always maintain the posture without being subjected to the force applied by the user or external force, and cannot move automatically, thereby facilitating the user to smoothly perform a series of operations such as video call and camera shooting at the angle, which are all within the protection scope of the patent.

[0071] More worth mentioning is that, referring to Figures 6 to 8 , the rotating mechanism 3 is configured to make the host 2 horizontally rotate relative to the base 1 within a range of 0-360 degrees, and referring to Figures 3 to 6 , the rotating mechanism 3 can also make the host 2 longitudinally flip relative to the base 1 within a range of 0-90 degrees, so that the screen 21 of the host 2 can have an orientation in any direction, thereby greatly improving the use scene of the smart watch. Of course, the first end 22 of the host 2 can always abut against the end face of the base 1 to form support for the host 2 and improve the stability of the structure when the orientation of the screen 21 changes.

[0072] In the embodiment, the dismounting mode of the host 2 and the second supporting plate 5 is not limited, and only needs to ensure that the host 2 can be quickly mounted and dismounted on the second supporting plate 5 and cannot move in any direction after being mounted on the second supporting plate 5, and any dismounting mode is within the protection scope of the patent.

[0073] As a preferred scheme of the embodiment, referring to Figure 1 , the host 2 is provided with a clamping block 24 on the side opposite to the screen 21 and adjacent to the central position of the first end 22, and the second supporting plate 5 is provided with a clamping hole 51 matched with the outline of the clamping block 24 at the corresponding position. The user can directly align the clamping block 24 of the host 2 with the clamping hole 51 of the second supporting plate 5, and then insert the clamping block 24 into the clamping hole 51, so as to complete the mounting of the host 2 on the second supporting plate 5.

[0074] In order to ensure that the host 2 and the second supporting plate 5 have a unique assembly posture, continuing to refer to Figure 1The card block 24 can be preferably arranged in a square block structure, and the card hole 51 can be arranged in a square hole structure matching the outline of the card block 24. Of course, the card block 24 can also be arranged in a multi-rib block structure according to actual use requirements, and the like. That is to say, it is only necessary to ensure that the outline of the card block 24 and the card hole 51 are matched, and the card block 24 cannot rotate along the axial direction of the card hole 51 after being clamped in the card hole 51. As a preferred, an annular card slot can be arranged on the circumferential edge of the card block 24, and a guide slope can be arranged on the edge of the card block 24 away from the host 2, the guide slope is used to guide the card block 24 into the card hole 51, and the annular card slot is used to form a limiting fit with the hole wall of the card hole 51 when the card block 24 is clamped in the card hole 51. In this way, it can be effectively ensured that the card block 24 cannot automatically separate from the card hole 51. Of course, when the user wants to detach the host 2 from the second supporting plate 5 to perform operations such as photographing, video shooting, and information viewing like a mobile phone, it is only necessary to exert a force greater than the clamping force of the card block 24 and the card hole 51 on the host 2, so that the host 2 and the second supporting plate 5 can be separated.

[0075] Of course, in the embodiment, in order to ensure that the host 2 can be completely stacked on the end surface of the base 1, an avoiding portion 25 can be preferably arranged on the side of the host 2 opposite to the screen 21 and adjacent to the second end 23, the avoiding portion 25 is matched with the outline of the rotating mechanism 3, and is used to enter the inside of the host 2 when the host 2 is stacked on the base 1, so as to avoid that the rotating mechanism 3 presses the host 2 and causes a gap between the host 2 and the base 1, thereby improving the compactness and aesthetics of the entire smart watch structure.

[0076] Further, in the embodiment, referring to Figure 1 and Figure 3 , the base 1 is further provided with a shielding portion 14 corresponding to the position of the first end 22 of the host 2, the shielding portion 14 protrudes from the end surface of the base 1, and is used to shield the gap between the first end 22 of the host 2 and the base 1 when the host 2 is stacked on the base 1, and can form a protection for the host 2. As a preferred, the shielding portion 14 can extend to both ends of the base 1 in the width direction, and is integrally formed with the base 1, but is not limited thereto.

[0077] 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 those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements should also be considered as the protection scope of the present application.
