All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.

Example 1

In this embodiment, a protection ring is provided, which includes a ring-shaped ring body 3, as shown in fig. 5 or 8, and in implementation, the ring body 3 preferably adopts a ring-shaped structure.

For convenience of description, a side of the ring body 3 near the center of the ring body (i.e., the center axis of the ring body 3, which will not be described in detail later) is referred to as an inner side 31, and correspondingly, a side of the ring body 3 facing away from the center of the ring body 3 is referred to as an outer side 32, in this embodiment, the inner side 31 of the ring body 3 is configured with a receiving groove 34 recessed in a direction facing away from the center axis of the ring body, i.e., the inner side 31 of the ring body 3 is configured with a receiving groove 34 recessed toward the outer side 32, and the receiving groove is adapted to at least a display part, so that the receiving groove can at least receive the display part. In this embodiment, the side surface of the receiving groove is closed, and for convenience of description, the structure surrounding the receiving groove is a side structure, that is, the receiving groove is surrounded by the side structure, and one end of the receiving groove facing the central axis of the ring body 3 is configured with an open notch, so that the display device 4 is mounted, and the other end corresponding to the notch is closed. In this embodiment, by forming the accommodating groove 34 adapted to the display device 4 on the inner side 31 of the ring body 3, on one hand, after the protective ring 2 is sleeved in the annular clamping groove 13, an assembling space 5 at least for accommodating the display device 4 can be formed between the protective ring 2 and the bottom of the annular clamping groove 13, as shown in fig. 6 and 9, which is convenient for assembling the display device 4, as shown in fig. 7 and 10, and can effectively reduce or even eliminate the pressure between the protective ring 2 and the display device 4, thereby effectively improving the stress condition of the display device 4 and being beneficial to improving the service life of the display device 4. On the other hand, the formation of the accommodation groove 34 makes it easier to quickly assemble and disassemble the display device 4, not only accommodates the display device 4, but also facilitates accommodation of a circuit board or the like for adapting the display device 4. Because holding tank 34 is sunken and shaping along the direction that deviates from circle body central axis for the inboard 31 of circle body 3 can form rugged structure, after the cover of protection circle 2 is located in the annular draw-in groove 13, enclose the lateral part structure of holding tank and also insert in annular draw-in groove 13 to can support in annular draw-in groove, on the one hand, lateral part structure can play the effect of supporting the protection circle, when protection circle 2 bumps with the foreign object in the use, collision force can be via lateral part structure disperses in the joint device 1 to the collision force that can greatly reduced display device 4 bore can effectively protect display device 4, reaches the purpose that improves display device 4 life and reliability. On the other hand, the side structure can form sealing fit with the annular clamping groove 13, so that the notch can be sealed by the annular clamping groove 13, the sealing effect of the assembly space 5 formed between the protective ring 2 and the annular clamping groove 13 is better, the functions of water resistance, moisture resistance, dust resistance and the like can be achieved, the display device 4 can be further protected, and the service life and reliability of the display device 4 are improved.

Because the ring body 3 adopts the ring structure preferentially, when implementing, the holding tank can be constructed into arc structure or annular structure preferentially, wherein, when the holding tank adopts the arc structure, its centre of a circle that corresponds can coincide with the central axis of the ring body 3, and when the holding tank adopts the annular structure, especially when adopting the ring structure, its centre of a circle that corresponds can coincide with the central axis of the ring body 3, so both can adapt annular ring body, can adapt to the display device of bigger area again, realize better display function.

In practice, the receiving groove 34 may be formed by machining a groove into the inner side 31 of the existing guard ring, as shown in fig. 8. In a more preferred embodiment, the inner side 31 of the ring body 3 is configured with at least two annular protrusions 33, as shown in fig. 5 or 8, wherein a receiving groove 34 for adapting to the display device 4 is formed between the two annular protrusions 33, the receiving groove 34 is of an annular structure, and the space between the two annular protrusions 33 is adapted to the width of the annular clamping groove 13 in the joint device 1, so that the two annular protrusions 33 can be inserted into the annular clamping groove 13 of the joint device 1 during assembly, so as to realize connection of the protective ring 2 and the joint device 1 and prevent the protective ring from falling off from the joint device 1. In practice, the receiving groove 34 is formed by constructing at least two annular projections 33, as shown in fig. 5, which facilitates a faster and simpler molding of the receiving groove 34. In addition, by constructing at least two annular protrusions 33 on the inner side 31 of the ring body 3, the annular protrusions 33 just form the side structure of the accommodating groove 34, that is, the annular protrusions 33 enclose the accommodating groove 34, so that when the protective ring is sleeved in the annular clamping groove 13, the two annular protrusions 33 forming the accommodating groove 34 can abut against the annular clamping groove 13, on one hand, the annular protrusions 33 can play a role in supporting the protective ring, and when the protective ring collides with an external object in use, the collision force can be dispersed into the joint device 1 through the annular protrusions 33, thereby greatly reducing the collision force born by the display device 4 and effectively protecting the display device 4. On the other hand, since the two annular protrusions 33 forming the accommodation groove 34 may be inserted into the annular clamping groove 13 of the engaging device 1, the annular protrusions 33 may form a sealing fit with the annular clamping groove 13, for example, the inner diameter of the annular protrusions 33 may be smaller than the diameter of the bottom surface in the annular clamping groove 13, so that the annular protrusions 33 and the bottom surface of the annular clamping groove 13 have pressure, and may have a sealing effect, thereby having waterproof, dampproof, dustproof effects, and further protecting the display device 4 in the assembly space 5, and improving the service life and reliability of the display device 4.

It will be appreciated that in practice, the central axis of the annular projection 33 may coincide with the central axis of the ring body 3.

In practice, the width of the guard ring along the central axis direction of the ring body 3 may be determined according to practical requirements, for example, in one embodiment, the width of the guard ring along the central axis direction of the ring body 3 may be adapted to the width of the annular clamping groove 13 in the engagement device 1, for example, the width of the guard ring along the central axis direction of the ring body 3 may be smaller than or equal to the width of the annular clamping groove 13 in the engagement device 1, and of course, may be slightly larger than the width of the annular clamping groove 13 in the engagement device 1. At this time, the guard ring may be provided only at a position corresponding to the annular clamping groove 13 in the joint device 1, as shown in fig. 6, so as to serve the purpose of protecting the joint device 1 and protecting the internal display device 4.

As another example, in another embodiment, the width of the guard ring 2 along the central axis of the ring body 3 may be larger than the width of the annular clamping groove 13 in the engagement device 1, as shown in fig. 11, so that the guard ring may cover not only the annular clamping groove 13 in the engagement device 1, but also other structures of the engagement device 1, as shown in fig. 12. In practice, a partial region of the inner side 31 of the ring body 3 is provided with two annular projections 33, which partial region corresponds to the annular clamping groove 13 in the engagement device 1, which two annular projections 33 are intended to be inserted into the annular clamping groove 13 of the engagement device 1; meanwhile, other areas of the inner side 31 of the ring body 3 may be further provided with annular protrusions 33, as shown in fig. 12, and these areas may be used to cover other structures than the annular protrusions 33 of the engaging device 1, so that the display device 4 may be protected more effectively by the present protective ring, for example, in some embodiments, the protective ring may cover not only the annular clamping groove 13 on the side of the engaging device 1, but also other areas of the outer side 32 outside the annular clamping groove 13, as shown in fig. 12, so as to better play a role of buffering and damping the engaging device 1, thereby being beneficial to better protecting the engaging device 1.

In practice, when the inner side 31 of the guard ring is provided with more than two annular protrusions 33, the receiving groove 34 may be preferentially formed between two adjacent annular protrusions 33 therein, as shown in fig. 11, which is advantageous in terms of simplification of structure, convenience of molding, and reduction of cost. Meanwhile, in the implementation, the construction position of the annular protrusion 33 can also be determined according to practical requirements, in a preferred embodiment, at least one annular protrusion 33 forming the accommodating groove 34 is located at the edge of the inner side 31 of the ring body 3, and by constructing the annular protrusion 33 at the edge of the inner side 31 of the ring body 3, not only the accommodating groove 34 with a larger area is facilitated to be adapted to the display device 4 with a larger area, but also the annular protrusion 33 is facilitated to be matched with the annular clamping groove 13 to achieve a better sealing effect; in addition, the molding process of the ring body 3 is simplified, and rapid molding is facilitated. As an example, when the present protective ring is used only to cover the annular clamping groove 13 of the engaging device 1, two annular protrusions 33 forming the accommodating groove 34 may be respectively located at the edges of the inner side 31 of the ring body 3, as shown in fig. 8 and 9, so as to fully utilize the space within the annular clamping groove 13. As another example, when the present protective ring may cover not only the annular clamping groove 13 of the engaging device 1 but also other areas or structures other than the annular clamping groove 13 in the present engaging device 1, one of the annular protrusions 33 forming the receiving groove 34 may be located at the edge of the inner side 31 of the ring body 3, and the other annular protrusion 33 forming the receiving groove 34 may be located generally at the middle position of the inner side 31 of the ring body 3 (i.e., at a position between the two edges of the inner side 31 of the ring body 3, not particularly, directly in the middle), as shown in fig. 11 and 12, and at this time, the annular protrusion 33 may be located within the annular clamping groove 13 of the engaging device 1 or may be located outside the annular clamping groove 13 of the engaging device 1.

In practice, the shape of the outer side 32 of the ring body 3 may be determined according to practical requirements, but in a preferred embodiment, the outer side 32 of the ring body 3 may be configured to protrude outwards in a direction away from the center of the ring body 3, so as to effectively increase the radial thickness of the ring body 3, and may play a role in better buffering and damping. As an example, as shown in fig. 5, along the direction from the upper edge of the outer side 32 to the lower edge of the outer side 32, the outer side 32 of the ring body 3 may be configured as a cambered surface, i.e., in the cross-sectional pattern of the ring body 3, the outer side 32 thereof is configured as a cambered shape, as shown in fig. 5 or 8, so as to eliminate the corner angle of the outer side 32 of the ring body 3, so that the outer side 32 of the ring body 3 is smoother, thereby improving the stress of the ring body 3 during collision, and being more beneficial to protecting the internal display device 4. In the present embodiment, the outer side 32 of the ring body 3 may be preferably configured as an arc surface.

In implementation, the ring body 3 can adopt an elastic ring body 3 or a plastic ring body 3 and the like so as to play a role in buffering and damping. In this embodiment, the ring body 3 preferably adopts the elastic ring body 3, so that the protection ring has elasticity, not only is the protection ring convenient to assemble, but also better sealing effect can be realized by utilizing the elasticity of the protection ring. Meanwhile, in order not to affect the display effect of the display device 4, the ring body 3 can transmit light, so that the elastic ring body 3 can be made of materials such as rubber, silica gel, and the like that can transmit light preferentially in implementation.
