[0008] As mentioned above, a plurality of plug blocks are arranged circumferentially on the bottom shell, and the plurality of plug blocks correspond to the plurality of connecting grooves one by one. Each plug block is connected to the bottom shell in a detachable manner. When each first rod moves to the end of the locking section away from the insertion section, each plug block is connected to the corresponding insertion section, and the plug blocks prevent the outer shell and the bottom shell from rotating relative to each other.
[0009] As mentioned above, a plurality of plug-in blocks are fixedly connected to the bottom shell along the circumferential direction, and the plurality of plug-in blocks correspond to a plurality of connecting grooves one by one. A plurality of bases are provided on the bottom shell, and each base corresponds to a first rod body. The first rod body is arranged to slide axially on the base, and a limit piece is provided at the connection between the first rod body and the bottom shell; the connection stroke between the outer shell and the bottom shell also includes: a third stroke, after each first rod body moves to the end of the locking section away from the insertion section, the outer shell is pushed to move axially so that the insertion section is plugged into the corresponding plug-in block, and the limit piece limits the movement of the first rod body.
[0010] As mentioned above, the limit member includes a second rod body arranged to slide radially on the first rod body, and in the sliding direction, a first elastic member is provided between the second rod body and the first rod body, the first rod body is an elastic telescopic structure, and a position corresponding to each first rod body on the bottom shell is provided with an extrusion groove, and each second rod body is correspondingly slidably connected to an extrusion groove; in the process of removing the outer shell from the bottom shell, the extrusion groove produces an extrusion effect on the second rod body along the length direction of the first rod body, and the elastic force generated by the shortening of the length of the first rod body limits the relative movement of the outer shell and the bottom shell.
[0011] As mentioned above, the extrusion groove includes an entry section, an extrusion section and a removal section, the extrusion section is arranged at an angle, and when the second rod body moves from the high end to the low end of the extrusion section, the length of the first rod body is shortened, the entry section is connected with the high end of the extrusion section, and along the length direction of the second rod body, the depth of the entry section is less than the depth of the extrusion section, the removal section is connected with the low end of the extrusion section, and along the length direction of the second rod body, the depth of the removal section is the same as that of the extrusion section.
[0012] As mentioned above, the length direction of the entry section and the length direction of the removal section are both parallel to the axial direction of the housing, and the shortest distance between the entry section and the removal section is less than the distance of the first rod body inserted into the connecting groove.

[0015] As mentioned above, pressure surfaces are arranged at both ends of the circumference of each part of the bottom shell, and an extrusion surface is arranged on the first rod body. When the second rod body continues to move after it detaches from the extrusion groove from the moving-out section, the extrusion surface squeezes the pressure surface, and the two adjacent parts of the bottom shell move away from each other. When the first rod body crosses the pressure surface and contacts the end surface corresponding to each part of the bottom shell, the two adjacent parts of the bottom shell can no longer abut against each other under the action of the rebound force of the second elastic member.
[0016] As mentioned above, the outer shell is provided with an escape space, and when the two adjacent parts of the bottom shell are squeezed and moved away from each other, the radial dimension of the bottom shell as a whole increases, and the escape space provides space for the increase of the radial dimension of the bottom shell as a whole.
[0017] The beneficial effect of the present invention is that by arranging a connecting groove on the outer shell and arranging a first rod body on the bottom shell, the outer shell can be fixed on the bottom shell in the two strokes in which the first rod body is connected to the corresponding connecting groove, and vice versa, the outer shell can be removed from the bottom shell, so that the wearer can conveniently change the style of the outer shell according to his or her own needs.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Figure 8 The present invention is further described in detail.
[0030] An embodiment of the present invention provides a ring with a replaceable appearance, including a ring body 1, wherein the body 1 includes a bottom shell 11 that contacts the wearer's skin and an outer shell 10 installed on the bottom shell 11, wherein electronic components are arranged in the bottom shell 11, and a plurality of first rods 2 are evenly arranged on the bottom shell 11 along the circumferential direction, and a plurality of connecting grooves 3 are evenly opened on the outer shell 10 along the circumferential direction, and the plurality of first rods 2 correspond to the plurality of connecting grooves 3 one by one; the connecting grooves 3 include an insertion section 30 axially parallel to the outer shell 10 and a locking section 31 perpendicular to the insertion end; the connection stroke between the outer shell 10 and the bottom shell 11 includes: a first stroke, each first rod 2 is inserted into the insertion section 30 of the corresponding connecting groove 3, and moves to the junction of the insertion section 30 and the locking section 31; a second stroke, the outer shell 10 is rotated, and each first rod 2 moves to the end of the locking section 31 away from the insertion section 30.
[0031] Specifically, the smart ring is a wearable device and also has a decorative function like a traditional metal ring. Its body 1 generally consists of a bottom shell 11 that contacts the skin of the wearer's finger and an outer shell 10. The bottom shell 11 has a space for arranging electronic components. The deficiency in the prior art is that the bottom shell 11 and the outer shell 10 are basically fixedly connected, and the style of the outer shell 10 is selected at the time of purchase. The size of the smart ring is relatively small, and it is extremely inconvenient for the wearer to replace the desired style at a later time.
[0032] Therefore, in the present embodiment, the bottom shell 11 and the outer shell 10 are made into a detachable structure so that the wearer can change the style of the outer shell 10 according to the needs, that is, the bottom shell 11 includes a contact portion 110 in contact with the skin, and a cavity 111 for installing electronic components is provided on the contact portion, and the cavity is sealed by a cover plate 112, and the cover plate 112 and the contact portion 110 are fixed by screws. In the axial direction of the bottom shell 11, a plurality of first rod bodies 2 are arranged on one side of the cavity 111, and the length direction of each first rod body 2 is parallel to the radial direction of the bottom shell 11 at its position. The outer shell 10 is arranged on the side of the bottom shell 11 away from the skin of the wearer's fingers. The outer shell 10 has a decorative effect, and a plurality of connecting grooves 3 are arranged on the inner side wall thereof facing the bottom shell 11, and the insertion section 30 of the connecting groove 3 is parallel to the axial direction of the outer shell 10, and the locking section 31 is in an arc shape, and its center is on the central axis of the outer shell 10. The angle between the segment 31 and the insertion end is a right angle. When the outer shell 10 is connected to the bottom shell 11, the first rod bodies 2 are first aligned axially with the insertion segments 30 of the connecting grooves 3, and then the outer shell 10 is pushed to move axially, so that each first rod body 2 is connected to the corresponding insertion segment 30, until the first rod body 2 reaches the junction of the corresponding insertion segment 30 and the locking segment 31, and then the outer shell 10 is rotated circumferentially, along the trajectory of the locking segment 31, so that the first rod body 2 reaches the end of the locking segment 31 away from the insertion segment 30, thereby completing the connection between the outer shell 10 and the bottom shell 11. Conversely, the outer shell 10 is first rotated so that the first rod body 2 moves along the trajectory of the locking segment 31 to the junction of the locking segment 31 and the insertion segment 30, and then the outer shell 10 is pulled axially to move, so that the first rod body 2 is separated from the connecting groove 3 along the insertion segment 30, thereby completing the separation of the outer shell 10 and the bottom shell 11.
[0033] The beneficial effect of this embodiment is that by providing a connecting groove 3 on the outer shell 10 and a first rod body 2 on the bottom shell 11, the outer shell 10 can be fixed on the bottom shell 11 in the two strokes in which the first rod body 2 is connected to the corresponding connecting groove 3, and vice versa, the outer shell 10 can be removed from the bottom shell 11, so that the wearer can easily change the style of the outer shell 10 according to his or her needs.
[0034] Preferably, a plurality of plug blocks 32 are arranged circumferentially on the bottom shell 11, and the plurality of plug blocks 32 correspond one-to-one to the plurality of connecting grooves 3. Each plug block 32 is plugged into the bottom shell 11 in a detachable manner. When each first rod body 2 moves to an end of the locking section 31 away from the insertion section 30, each plug block 32 is connected to the corresponding insertion section 30, and the plug blocks 32 prevent the outer shell 10 and the bottom shell 11 from rotating relative to each other.
[0035] Specifically, in the aforementioned embodiment, when the first rod body 2 is at the end of the locking section 31 away from the insertion section 30, in the axial direction of the shell 10 or in a direction substantially close to the axial direction, after the shell 10 is hit, due to the cooperation restriction of the first rod body 2 and the locking section 31, the shell 10 will not move relative to the bottom shell 11. However, if the collision force has a component force in the tangential direction of the shell 10, or a force directly parallel to the component force acts on the shell 10, so that the shell 10 and the bottom shell 11 rotate relative to each other, then there is a problem of separation between the shell 10 and the bottom shell 11. The radial dimension of the shell 10 is necessarily greater than the radial dimension of the bottom shell 11. After the shell 10 and the bottom shell 11 rotate relative to each other, the shell 10 may fall off. Therefore, in this embodiment, a plurality of plug blocks 32 are arranged on the bottom shell 11 along the circumferential direction. The plug blocks 32 are connected to the bottom shell 11 in a detachable manner, that is, a slot for inserting the plug blocks 32 can be provided on the bottom shell 11. The friction resistance between the block 32 and the corresponding slot is used to solve the problem that the block 32 is easy to fall off. In this way, when the first rod body 2 moves to the end of the locking section 31 away from the insertion section 30, the block 32 is plugged into the corresponding slot. At the same time, the slot is also aligned with a certain insertion section 30. In this way, the block 32 is plugged into the slot and also into the insertion section 30. The block 32 limits the relative rotation of the outer shell 10 and the bottom shell 11, while the first rod body 2 and the locking section 31 limit the relative movement of the outer shell 10 and the bottom shell 11. In this way, the outer shell 10 can avoid falling off after a collision. When replacing the outer shell 10, the block 32 can be removed from the slot by a tool. For example, a wedge-shaped hole can be opened on the block 32, and a strip-shaped object with a wedge-shaped structure can be inserted into the wedge-shaped hole, so that the block 32 is lifted out of the slot (this is a prior art and is not repeated and is not shown in the figure). Then the separation of the outer shell 10 and the bottom shell 11 is carried out in the manner described in the aforementioned embodiment.
[0036] In another embodiment of the present invention, a plurality of plug blocks 32 are fixedly connected to the bottom shell 11 along the circumferential direction, and the plurality of plug blocks 32 correspond one-to-one to the plurality of connecting grooves 3. A plurality of bases 4 are provided on the bottom shell 11, and each base 4 corresponds to a first rod body 2. The first rod body 2 is axially slidably arranged on the base 4, and a limit piece is provided at the connection between the first rod body 2 and the bottom shell 11; the connection stroke between the outer shell 10 and the bottom shell 11 also includes: a third stroke, after each first rod body 2 moves to the end of the locking section 31 away from the insertion section 30, the outer shell 10 is pushed to move along the axial direction so that the insertion section 30 is plugged into the corresponding plug block 32, and the limit piece limits the movement of the first rod body 2.
[0037] Specifically, in the aforementioned embodiment, although the arrangement of the plug block 32 and the slot can prevent the shell 10 from rotating relative to the bottom shell 11 after a collision, it is troublesome to disassemble the plug block 32 when replacing the shell 10. Therefore, in this embodiment, another method is adopted to restrict the relative movement of the shell 10 and the bottom shell 11, that is, a plurality of plug blocks 32 are fixed to the bottom shell 11, the base 4 will not move axially on the bottom shell 11, and the first rod body 2 can slide axially on the corresponding base 4, that is, each base 4 is provided with a slideway for the first rod body 2 to slide axially, and a limiter is provided at a position corresponding to the first rod body 2 and the bottom shell 11, so that the shell 10 and the bottom shell 11 are relatively fixed. On the basis of the first two strokes connected by the first rod body 2, a third stroke is added, that is, after the first rod body 2 enters the insertion section 30 and then enters the end of the locking section 31 away from the insertion section 30, the housing 10 is pushed to move in the axial direction again, so that the two sides of the housing 10 in the axial direction are aligned with the two sides of the bottom shell 11 in the axial direction, and in this process, the insertion section 30 is plugged into the corresponding plug block 32, and the position of the first rod body 2 is limited by the limiter, so that the axial relative movement of the housing 10 and the bottom shell 11 is limited, and the circumferential relative rotation is limited. After that, the housing 10 is disassembled from the bottom shell 11, the limit of the limiter is removed, and the housing 10 is moved in the opposite directions of the three strokes, so that the force distribution of the housing 10 and the bottom shell 11 can be achieved.
[0038] The use of the limit member not only ensures a stable connection between the outer shell 10 and the bottom shell 11, but also facilitates the removal of the outer shell 10 from the bottom shell 11. Therefore, in a preferred embodiment, the limit member includes a second rod 5 radially slidably arranged on the first rod 2, and in the sliding direction, a first elastic member is provided between the second rod 5 and the first rod 2, and the first rod 2 is an elastic telescopic structure. An extrusion groove 6 is provided at a position corresponding to each first rod 2 on the bottom shell 11, and each second rod 5 is slidably connected to an extrusion groove 6; in the process of removing the outer shell 10 from the bottom shell 11, the extrusion groove 6 produces an extrusion effect on the second rod 5 along the length direction of the first rod 2, and the elastic force generated by the shortening of the length of the first rod 2 limits the relative movement of the outer shell 10 and the bottom shell 11.
[0039] Specifically, the length direction of the second rod body 5 is perpendicular to the axial direction of the housing 10, and at the position of the first rod body 2, the length direction of the second rod body 5 is parallel to the tangent direction of the bottom shell 11 at the position, and the second rod body 5 can slide along the direction in which it is located on the first rod body 2, and the first rod body 2 is an elastic telescopic structure in its own length direction, that is, it can be shortened after being compressed, and can be extended under the action of its own resilience after the pressure is removed. A plurality of extrusion grooves 6 are provided on the bottom shell 11, and each second rod body 5 is slidably connected to an extrusion groove 6. When the first rod body 2 slides in the corresponding extrusion groove 6, the extrusion groove 6 can give The first rod 2 is given a force in the extension and contraction direction of the first rod 2. The extrusion groove 6 is arranged so that when the outer shell 10 is removed from the bottom shell 11, the extrusion groove 6 generates a force to compress the first rod 2 on the second rod 5, so that the first rod 2 shortens and the elastic force increases. In this way, the friction force between the second rod 5 and the extrusion groove 6 is increased, thereby playing a certain elastic limiting role. When the outer shell 10 is hit by an external force, a certain limit and buffering are performed. When the wearer needs to replace the outer shell 10, he only needs to push the outer shell 10 to move so that the second rod 5 slides out of the extrusion groove 6, and then the outer shell 10 can be disassembled according to the method of the aforementioned embodiment.
[0040] During the sliding of the second rod body 5 in the extrusion groove 6, the distance by which the first rod body 2 is shortened by the extrusion of the extrusion groove 6 should be controlled so that the first rod body 2 will not be separated from the locking section 31, thereby ensuring that the shell 10 will not be separated from the bottom shell 11. Therefore, in an optional embodiment, the extrusion groove 6 includes an entry section 60, an extrusion section 61 and a removal section 62, and the extrusion section 61 is arranged obliquely. During the movement of the second rod body 5 from the high end to the low end along the extrusion section 61, the length of the first rod body 2 is shortened, the entry section 60 is connected with the high end of the extrusion section 61, and along the length direction of the second rod body 5, the depth of the entry section 60 is less than the depth of the extrusion section 61, the removal section 62 is connected with the low end of the extrusion section 61, and along the length direction of the second rod body 5, the depth of the removal section 62 is the same as that of the extrusion section 61; the length direction of the entry section 60 and the length direction of the removal section 62 are both parallel to the axial direction of the shell 10, and the shortest distance between the entry section 60 and the removal section 62 is less than the distance of the first rod body 2 inserted into the connecting groove 3.
[0041] Specifically, when the second rod 5 is not subjected to an external force to generate a shortening force on the first rod 2, the first rod 2 is in a fully extended state. At this time, the second rod 5 is aligned with the entry section 60 in the axial direction of the outer shell 10. In this way, when the outer shell 10 is installed on the bottom shell 11, the insertion section 30 is directly aligned with the first rod 2 in the axial direction. This can be done in accordance with the manner in which the outer shell 10 and the bottom shell 11 are connected in the aforementioned embodiment. When the outer shell 10 is collided by an external force, the second rod 5 should directly enter the extrusion section 61. Therefore, along the length direction of the second rod 5, the depth of the entry section 60 is less than the depth of the extrusion section 61. In this way, the second rod 5 reaches the high end of the extrusion section 61 from the entry section 60. When the outer shell 10 is subjected to an external force, the insertion section 30 is directly aligned with the first rod 2 in the axial direction. When the second rod 5 moves relative to the bottom shell 11 in the axial direction, the second rod 5 moves along the inclined direction of the extrusion section 61, and the extrusion force given to the second rod 5 by the extrusion section 61 is applied to the first rod 2. The first rod 2 shortens to generate elastic force, thereby increasing the friction force between the second rod 5 and the extrusion section 61. When the shell 10 needs to be replaced, the second rod 5 directly enters the removal section 62 from the extrusion section 61, and then the second rod 5 is completely separated from the extrusion groove 6, wherein the shortest distance between the entry section 60 and the removal section 62 is less than the distance of the first rod 2 inserted into the connecting groove 3, thereby ensuring that after the second rod 5 reaches the lower end from the high end of the extrusion section 61, the compression length of the first rod 2 will not cause it to be separated from the locking section 31.
[0042] In another embodiment of the present invention, the bottom shell 11 is split, and is evenly divided into several parts in the circumferential direction, and two adjacent parts are connected by an elastic component 7.
[0043] Specifically, when wearing a ring, it is necessary to choose a suitable size to ensure that it is comfortable to wear and difficult to fall off the wearer's finger. After the ring is worn, the wearer's joints may be thicker than the finger pulp, or the finger pulp may have more flesh, which may hinder the removal of the ring. Therefore, in this embodiment, the bottom shell 11 is set as a split structure, which is evenly divided into several parts in the circumferential direction, the number of which is the same as the number of the first rod body 2, and the two adjacent parts are connected by an elastic component 7, that is, the elastic force of the elastic component 7 is used to make the two adjacent parts abut against each other to form a complete ring. When wearing or taking off the ring, the diameter of the ring can also be appropriately enlarged to facilitate wearing or taking off.
[0044] In a preferred embodiment, the elastic component 7 includes a slide groove 70 provided at both ends of each part of the bottom shell 11 in the circumferential direction, a slider 71 is slidably provided in the slide groove 70, and in the sliding direction, a second elastic member is provided between the slide groove 70 and the slider 71, and the junction between the two adjacent parts of the bottom shell 11 corresponds to a base 4 respectively, and the slider 71 is connected to the base 4 at a similar position through an elastic plate body 72. Under the elastic force of the second elastic member, the two adjacent parts of the bottom shell 11 tend to abut against each other, and the junction between the two adjacent parts of the bottom shell 11 corresponds to a locking section 31 respectively, and each locking section 31 is divided into two parts, which are respectively placed on the two adjacent parts of the bottom shell 11.
[0045] Specifically, the sliding track of the slider 71 in the slide groove 70 is parallel to the arc track of each part of the bottom shell 11. Each two adjacent parts of the bottom shell 11 correspond to a base 4. Each slider 71 is connected to the corresponding base 4 through an elastic plate 72. When the two adjacent parts of the bottom shell 11 are separated, the overall radial size of the bottom shell 11 is enlarged, so the elastic plate 72 can adapt to its change through elastic deformation, and the deformation direction of the elastic plate 72 is parallel to a certain radial direction of the shell 10. Under the elastic force of the second elastic member, the two adjacent parts of the bottom shell 11 tend to abut against each other, so that The elastic connection between the two adjacent parts of the bottom shell 11 and the elastic force of the second elastic member can provide an obstacle for the extrusion surface 20 to squeeze the pressure surface 8 after the second rod body 5 is separated from the extrusion groove 6 from the corresponding removal section 62, which is equivalent to providing a secondary obstacle for the outer shell 10 to separate from the bottom shell 11 along the axial direction after the collision, wherein the locking section 31 is divided into two, which are placed on the two adjacent parts of the bottom shell 11, and at this time, a part of the locking section 31 will be connected to the insertion section 30, and the other part can also be arranged with an insertion section 30, and accordingly, another plug block 32 is also arranged on the bottom shell 11 to be plugged into the inserted section 30 arranged again.
[0046] Furthermore, pressure surfaces 8 are arranged at both circumferential ends of each part of the bottom shell 11, and an extrusion surface 20 is arranged on the first rod body 2. When the second rod body 5 continues to move after detaching from the extrusion groove 6 from the moving-out section 62, the extrusion surface 20 squeezes the pressure surface 8, and the two adjacent parts of the bottom shell 11 move away from each other. When the first rod body 2 crosses the pressure surface 8 and contacts the corresponding end surface of each part of the bottom shell 11, the two adjacent parts of the bottom shell 11 can no longer abut against each other under the action of the rebound force of the second elastic member; an avoidance space 9 is arranged on the outer shell 10. When the two adjacent parts of the bottom shell 11 are squeezed and moved away from each other, the overall radial size of the bottom shell 11 increases, and the avoidance space 9 provides space for the increase in the overall radial size of the bottom shell 11.
[0047] Specifically, the extrusion surface 20 and the corresponding pressure surface 8 realize the extrusion action by wedge-shaped cooperation. In the process of separating the outer shell 10 from the bottom shell 11, the first rod body 2 drives the second rod body 5 from the extrusion section 61 into the removal section 62 and then moves out from the removal section 62. Then, the extrusion surface 20 on the first rod body 2 contacts with the pressure surface 8 and exerts an extrusion effect on it, so that the two adjacent parts of the bottom shell 11 are separated. When the two adjacent parts of the bottom shell 11 are separated, the overall radial size of the bottom shell 11 is enlarged. The outer shell 10 is an integral structure, so it is necessary to arrange an avoidance space 9 on the inner side wall of the outer shell 10 close to the bottom shell 11. When the extrusion surface 20 is offset from the corresponding pressure surface 8, the first rod body 2 is located between the two adjacent parts of the bottom shell 11, and the two parts are hindered from abutting against each other by the rebound force of the second elastic member, so that the bottom shell 11 with an overall enlarged radial size remains unchanged, and then the ring can be removed from the wearer's finger as a whole, and then the outer shell 10 is rotated to align the first rod body 2 with the insertion section 30, and the outer shell 10 is removed from the bottom shell 11. The advantage of such a setting is that the outer shell 10 is pushed to move in the direction of disassembling the outer shell 10, so that the overall radial size of the bottom shell 11 becomes larger, thereby making it convenient for the wearer to take off or wear the ring.
