Waterproof gasket, watch faceplate and watch case

Abstract

This invention relates to a waterproof ring, a watch light-transmitting panel, and a watch protective case. The watch protective case includes a watch screen protective panel, a waterproof ring, and a housing. The watch screen protective panel and the waterproof ring constitute the watch light-transmitting panel. The waterproof ring includes a first ring and a second ring connected along its axial direction. The first ring can adhere to the watch screen protective panel, and the second ring can abut against the watch screen. The second ring and the first ring are set at an acute angle, and the first and second rings form a deformation space at the acute angle. When the watch screen presses against the second ring, the angle between the first and second rings decreases, the abutment force between the second ring and the watch screen increases, and the abutment becomes tighter. The contact area between the second ring and the watch screen increases, thereby preventing gaps from forming between the waterproof ring and the watch screen when the watch screen exerts excessive pressure on the waterproof ring, which could allow water to enter the watch screen.

Description

[0001] This application claims priority to two Chinese patent applications filed on August 18, 2023, with application number 2023110517954, entitled "Smartwatch Protective Case and Smartwatch", and on December 26, 2023, with application number 2023235649089, entitled "A Glass Waterproof Ring Structure", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of watch technology, and in particular to a waterproof ring, a watch light-transmitting panel, and a watch protective case. Background Technology

[0003] As life becomes increasingly diverse, the demand for waterproof functionality in watches is also gradually increasing. Users typically use waterproof watch cases to protect their watches. A waterproof gasket is usually placed between the watch and the crystal of the protective case. The gasket comes into contact with the watch face, creating a sealed waterproof space between the watch dial and the crystal of the protective case, thus achieving the effect of waterproofing the watch. Traditionally, the waterproof gasket has a ring structure with a circular or square cross-section, and is placed between the crystal and the protective case to form a waterproof space.

[0004] However, traditional waterproof rings generally have limited pressure resistance and are prone to damage when squeezed between the watch crystal and the case. Furthermore, since the waterproof rings are not attached to the watch dial, gaps can easily appear under high pressure, allowing water to enter the waterproof space. Summary of the Invention

[0005] This invention provides a waterproof ring, a watch light-transmitting panel, and a watch protective case to solve the problem that when the waterproof ring is not attached to the watch, gaps can easily appear, causing water to enter the waterproof space.

[0006] A waterproof ring includes a first ring body and a second ring body, the first ring body and the second ring body are connected along the axial direction of the waterproof ring, the first ring body and the second ring body are set at an acute angle, and the first ring body and the second ring body form a deformation space at the acute angle; the first ring body is used to adhere to the watch screen protection panel, and the second ring body is used to abut against the watch screen.

[0007] In one embodiment, the deformation space is located outside the waterproof ring, and the inner surface of the second ring is a conical surface, with the inner diameter of the conical surface gradually decreasing along the axial direction of the waterproof ring from the second ring towards the first ring.

[0008] In one embodiment, the first ring body is provided with a first connecting surface, which is located on the side of the first ring body close to the second ring body and is perpendicular to the axial direction of the waterproof ring. The second ring body is provided with a second connecting surface on the side facing away from the conical surface. The first connecting surface and the second connecting surface are set at an acute angle and form the deformation space.

[0009] In one embodiment, the circumferential contour of the conical surface is the same as the outer contour of the watch screen. When the second ring is installed on the watch screen, the conical surface abuts against the watch screen, and the contact point between the conical surface and the watch screen forms a circumferentially closed ring. When the watch screen continues to press the conical surface, the second ring deforms and accumulates elastic force. The angle between the second connecting surface and the first connecting surface decreases, and the deformation space decreases, so as to increase the abutment elastic force of the conical surface against the watch screen and increase the contact area between the conical surface and the watch screen.

[0010] In one embodiment, the second connecting surface is a structure that is closed circumferentially along the second ring body, and each part of the second connecting surface is parallel to the corresponding conical surface, so that the second connecting surface and the conical surface have the same degree of deformation.

[0011] A waterproof ring includes a first ring body and a second ring body, the first ring body and the second ring body are connected along the axial direction of the waterproof ring, the second ring body extends obliquely from the inner side of the first ring body toward the outer side of the first ring body, and a deformation space is formed between the portion of the second ring body extending obliquely to the outer side and the first ring body, the deformation space being located on the outer side of the waterproof ring; the first ring body is used to adhere to the watch screen protective panel, and the second ring body is used to abut against the watch screen.

[0012] In one embodiment, the first ring body is provided with a first connecting surface, which is located on the side of the first ring body close to the second ring body. The first connecting surface is inclined to the axial direction of the waterproof ring. The outer surface of the second ring body is a second connecting surface. The angle between the first connecting surface and the second connecting surface is greater than or equal to 90 degrees and forms the deformation space.

[0013] In one embodiment, the inner surface of the second ring is a conical surface, and the circumferential contour of the conical surface is the same as the outer contour of the watch screen. When the second ring is installed on the watch screen, the conical surface abuts against the watch screen, and the contact point between the conical surface and the watch screen forms a circumferentially closed ring. When the watch screen continues to press the conical surface, the second ring deforms and accumulates elastic force. The angle between the second connecting surface and the first connecting surface decreases, and the deformation space decreases, so as to increase the abutment elastic force of the conical surface against the watch screen and increase the contact area between the conical surface and the watch screen.

[0014] A watch light-transmitting panel includes a watch screen protection panel and the aforementioned waterproof ring, wherein the first ring body is adhered to the watch screen protection panel.

[0015] A watch protective case includes a housing and the aforementioned watch light-transmitting panel. A light-transmitting window and a light-transmitting opening are sequentially provided from the front to the back of the housing. The watch screen protective panel is fixedly disposed on the inner wall of the light-transmitting opening.

[0016] As can be seen from the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:

[0017] The present invention relates to a waterproof ring, a watch screen protective panel, and a watch protective case. The waterproof ring is bonded to the watch screen protective panel to form the watch screen protective panel, thereby protecting the watch screen. The waterproof ring includes a first ring and a second ring, which are connected along the axial direction of the waterproof ring. The first ring and the second ring are set at an acute angle, and a deformation space is formed at the acute angle. The first ring can bond to the watch screen protective panel, and the second ring is used to abut against the watch screen. When the watch screen increases and compresses the second ring, the angle between the first ring and the second ring decreases, the contact force between the second ring and the watch screen increases, and the contact becomes tighter, enhancing the waterproof ring's resistance to compression deformation. This prevents gaps from forming between the waterproof ring and the watch screen when the watch screen compresses the waterproof ring excessively, thus preventing water from entering the watch screen.

Detailed Implementation

[0031] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] Please refer to the following first. Figure 1 and Figure 2 The present invention provides a waterproof ring 300, one side of which is bonded to the watch screen protection panel 400, and the other side of which is used to abut against the watch screen 51, thereby achieving the waterproof effect of the watch screen 51. The watch can be a smart wearable watch. Specifically, the waterproof ring 300 includes a first ring body 310 and a second ring body 320. The first ring body 310 is used to bond the watch screen protection panel 400, and the second ring body 320 is used to abut against the watch screen 51. The first ring body 310 and the second ring body 320 are connected along the axial direction of the waterproof ring 300, and the first ring body 310 and the second ring body 320 are set at an acute angle. When the watch screen protection panel 400 presses against the first ring body 310 and the watch screen 51 presses against the second ring body 320, the included angle between the second ring body 320 and the first ring body 310 decreases, making the second ring body 320 abut against the watch screen 51 more tightly, enhancing the waterproof ring 300's resistance to compression deformation, and preventing gaps from appearing between the waterproof ring 300 and the watch screen 51 when the pressure of the watch screen 51 on the waterproof ring 300 is too great, which would cause water to enter the watch screen 51.

[0035] refer to Figures 2 to 5Both the first ring 310 and the second ring 320 are circumferentially closed annular structures, and the axis of the first ring 310 is the same as the axis of the second ring 320, so that the central areas of the first ring 310 and the second ring 320 are connected and allow light to pass through the watch screen 51. The first ring 310 and the second ring 320 are integrally cast and molded. Both the first ring 310 and the second ring 320 are made of elastic material so that the waterproof ring 300 can deform and accumulate elastic force when it comes into contact with the watch screen 51. The connection between the first ring 310 and the second ring 320 is at an acute angle, and the first ring 310 and the second ring 320 form a deformation space 330 at the acute angle. The size of the deformation space 330 can change when the first ring 310 and the second ring 320 are compressed, and the second ring 320 and the first ring 310 store elastic force to enhance the sealing performance of the waterproof ring 300 when it comes into contact with the watch screen 51.

[0036] It should be noted that the outer contours of the first ring 310 and the second ring 320 are the same as the outer contours of the watch screen 51. The outer contours of both the first ring 310 and the second ring 320 are square to ensure that there are no gaps between the second ring 320 and the watch screen 51 when they are fitted together. It is understood that the first ring 310 and the second ring 320 can also be set to other shapes to meet the needs of different watch sizes. The two adjacent inner surfaces of the second ring 320 are connected by a rounded surface structure to allow the second ring 320 to fit better against the watch screen 51. When the watch screen 51 compresses the second ring 320, the rounded surface structure can reduce stress concentration, improve the compression resistance and durability of the second ring 320, make it easier to return to its original shape during the compression process, and improve the sealing performance.

[0037] In this embodiment, the deformation space 330 is located outside the waterproof ring 300, that is, the deformation space 330 is located on the side of the second ring 320 facing away from the center of the ring. The inner surface of the side of the second ring 320 facing the center of the ring is set as a conical surface 322. The conical surface 322 abuts against the watch screen 51. The conical surface 322 is a circumferentially closed cone. The space enclosed by the conical surface 322 is a conical space. Along the axial direction of the waterproof ring 300 from the second ring 320 towards the first ring 310, the inner diameter of the conical surface 322 gradually decreases, so that when the second ring 320 abuts against the watch screen 51, the contact area between the second ring 320 and the watch screen 51 increases, thereby preventing water from entering. The contact surface between the second ring 320 and the watch screen 51 is easily utilized to improve the waterproof effect of the waterproof ring 300. It should be noted that in other embodiments, the deformation space 330 can also be set inside the waterproof ring 300, that is, the deformation space 330 is located on the side of the second ring 320 facing the center of the ring. Along the axial direction of the waterproof ring 300 from the second ring 320 towards the first ring 310, the inner diameter of the conical surface 322 gradually increases. When the watch screen 51 squeezes the second ring 320, the deformation space 330 decreases, allowing the second ring 320 to accumulate elasticity and increase the contact force with the watch screen 51, thereby making the contact between the waterproof ring 300 and the watch screen 51 tighter.

[0038] The first ring body 310 is provided with a first connecting surface 311, which is located on the side of the first ring body 310 close to the second ring body 320. The first connecting surface 311 is connected to the second ring body 320 and is perpendicular to the axial direction of the waterproof ring 300. The second ring body 320 is provided with a second connecting surface 321 on the side facing away from the conical surface 322. The second connecting surface 321 is inclined to the axial direction of the waterproof ring 300 and is connected to the first connecting surface 311 at an acute angle. The included angle between the second connecting surface 321 and the first connecting surface 311 forms a deformation space 330. When the included angle between the second connecting surface 321 and the first connecting surface 311 is 45 degrees to 75 degrees, the waterproof effect and deformation effect of the waterproof ring 300 are the best.

[0039] The circumferential contour of the conical surface 322 is the same as the outer contour of the watch screen 51, so that the conical surface 322 can fit tightly against the watch screen 51. When the second ring body 320 abuts against the watch screen 51, the conical surface 322 contacts the watch screen 51, and the contact point between the conical surface 322 and the watch screen 51 forms a circumferentially closed ring, so that no gaps are formed between the conical surface 322 and the watch screen 51 in the circumferential direction, which would cause water to enter. When the watch screen 51 continues to press the conical surface 322, the second ring body 320 deforms and accumulates elastic force. At this time, the included angle between the second connecting surface 321 and the first connecting surface 311 decreases, the deformation space 330 decreases, the abutting elastic force of the conical surface 322 against the watch screen 51 increases, and the fit between the conical surface 322 and the watch screen 51 becomes tighter. Furthermore, due to the deformation of the second ring body 320, the adhesion area between the conical surface 322 and the watch screen 51 increases, thereby enhancing the waterproof performance of the waterproof ring 300.

[0040] The second connecting surface 321 is a circumferentially closed structure along the second ring body 320. Along the axial direction of the waterproof ring 300, from the second ring body 320 towards the first ring body 310, the axial distance between the second connecting surface 321 and the waterproof ring 300 gradually decreases. In this embodiment, each part of the second connecting surface 321 is parallel to the corresponding conical surface 322, so that when the watch screen 51 presses the conical surface 322, the deformation degree of the second connecting surface 321 and the conical surface 322 is the same. It should be noted that the second connecting surface 321 can also be at an angle to the conical surface 322. For example, the inclination degree of the conical surface 322 relative to the axial direction of the waterproof ring 300 is greater than the inclination degree of the second connecting surface 321 relative to the axial direction of the waterproof ring 300. That is, the angle between the second connecting surface 321 and the first connecting surface 311 is greater than the angle between the conical surface 322 and the first connecting surface 311. Under this structure, when the watch screen 51 presses the conical surface 322, the second ring body 320 is less likely to undergo excessive deformation and be damaged.

[0041] It is understood that in other embodiments, the angle between the first ring 310 and the second ring 320 may be greater than or equal to 90 degrees. The second ring 320 extends obliquely from the inner side of the first ring 310 toward the outer side of the first ring 310. A deformation space 330 is formed between the portion of the second ring 320 extending obliquely toward the outer side and the first ring 310. The deformation space 330 is located on the outer side of the waterproof ring 300. The first ring 310 is also provided with a first connecting surface 311. The first connecting surface 311 is located on the side of the first ring 310 closer to the second ring 320. The first connecting surface 311 is inclined to the axial direction of the waterproof ring 300. Along the axial direction of the waterproof ring 300, from the second ring 320 toward the direction closer to the first ring 310, the distance from the first connecting surface 311 to the axis of the waterproof ring 300 gradually increases. The first connecting surface 311 forms a circumferentially closed surface around the first ring 310. The outer surface of the second ring 320 is also provided with a second connecting surface 321. The second connecting surface 321 is inclined to the axial direction of the waterproof ring 300. Along the axial direction of the waterproof ring 300, from the second ring body 320 towards the first ring body 310, the distance from the second connecting surface 321 to the axis of the waterproof ring 300 gradually decreases. The included angle between the first connecting surface 311 and the second connecting surface 321 can be greater than or equal to 90 degrees. The included angle between the first connecting surface 311 and the second connecting surface 321 forms a deformation space 330. When the watch screen 51 presses against the inner surface of the second ring body 320, the second ring body 320 deforms and accumulates elastic force. At this time, the included angle between the second connecting surface 321 and the first connecting surface 311 decreases, which reduces the deformation space 330. The abutment elastic force of the inner surface of the second ring body 320 against the watch screen 51 increases, making the second ring body 320 and the watch screen 51 fit more tightly. The adhesion area between the inner surface of the second ring body 320 and the watch screen 51 increases, thereby enhancing the waterproof performance of the waterproof ring 300.

[0042] refer to Figure 2 The present invention also provides a watch light-transmitting panel 30, which includes a watch screen protection panel 400 and the aforementioned waterproof ring 300. The watch screen protection panel 400 is used to protect the watch screen 51 and prevent the watch screen 51 from being scratched. The watch screen protection panel 400 is made of a light-transmitting material. The watch screen protection panel 400 is bonded to the side of the first ring 310 facing away from the second ring 320. The thickness direction of the watch screen protection panel 400 is parallel to the axial direction of the waterproof ring 300. When the watch screen protection panel 400 is bonded to the first ring 310, the opening space on the side of the first ring 310 facing away from the second ring 320 is closed by the watch screen protection panel 400, and the bonding joint between the watch screen protection panel 400 and the first ring 310 is sealed and waterproof.

[0043] refer to Figures 6 to 9The present invention also provides a watch protective case 1, which includes a housing 20 and the aforementioned watch light-transmitting panel 30. The housing 20 is fitted onto the watch body 5 to protect the watch body 5 from damage. The housing 20 is provided with a front side 21 and a back side 22. Along the direction from the front side 21 to the back side 22, the housing 20 is provided with a light-transmitting window 23 and a light-transmitting opening 24 in sequence from the front side 21. The light-transmitting window 23 allows the watch screen 51 to be displayed. The watch body 5 can be installed in the light-transmitting opening 24. The watch screen protective panel 400 is bonded to a waterproof ring 300, and the edge of the waterproof ring 300 is located inside the edge of the watch screen protective panel 400. The watch screen protective panel 400 is fixedly disposed on the inner wall of the light-transmitting opening 24. The waterproof ring 300 is located inside the light-transmitting opening 24, and the watch screen protective panel 400 is located on the side of the light-transmitting opening 24 near the light-transmitting window 23.

[0044] A light-transmitting window 23 is located on the front 21. When the watch body 5 is installed in the light-transmitting opening 24, the watch screen 51 is close to the front 21. The waterproof ring 300 is located between the watch screen protection panel 400 and the watch body 5. The light from the watch screen 51 passes through the watch screen protection panel 400 and the light-transmitting window 23 and enters the human eye. The light-transmitting window 23 has an open structure, which extends through the front 21 and communicates with the light-transmitting opening 24. The light-transmitting opening 24 has a locking groove 241 on the inner wall of the side near the light-transmitting window 23. The edge of the watch screen protection panel 400 can be inserted into the locking groove 241, and the distance between the edge of the waterproof ring 300 and the edge of the watch screen protection panel 400 is greater than the depth of the locking groove 241, thereby fixing the watch screen protection panel 400.

[0045] The inner wall of the light-transmitting opening 24 is provided with a protruding edge 242 and a snap-fit ​​edge 243. The protruding edge 242 and the snap-fit ​​edge 243 are arranged at intervals relative to each other along the direction from the front side 21 to the back side 22. A circumferentially closed stepped surface structure is formed between the front side 21 and the inner wall of the light-transmitting opening 244. This stepped surface structure is the protruding edge 242. The side of the protruding edge 242 facing away from the snap-fit ​​edge 243 is located on the front side 21. The interval between the protruding edge 242 and the snap-fit ​​edge 243 forms a snap-fit ​​groove 241. It can be understood that the snap-fit ​​groove 241 is two spaced-out grooves extending from the inner wall of the light-transmitting opening 24 towards the center of the light-transmitting opening 24. In other embodiments, the snap-fit ​​groove 241 can also be formed by the inner wall of the light-transmitting opening 24 being recessed. For example, the inner wall of the light-transmitting opening 24 is recessed in a direction away from the center of the light-transmitting opening 24 to form a groove structure, which is the snap-fit ​​groove 241. When the watch screen protection panel 400 is snapped into the snap-fit ​​groove 241, the edge of the watch screen protection panel 400 is first deformed by the inner wall of the light-transmitting opening 24, and then the watch screen protection panel 400 is pushed and its edge slides into the snap-fit ​​groove 241 to achieve the fixed installation of the watch screen protection panel 400.

[0046] It should be noted that in other embodiments, the light-transmitting window 23 can also be configured as a closed structure. For example, the light-transmitting window 23 is set on the front 21 and closes the light-transmitting opening 24. The light-transmitting window 23 is made of a light-transmitting material, such as light-transmitting plastic. The light-transmitting window 23 and the housing 20 are integrally cast. In this case, the inner wall of the light-transmitting opening 24 can only be provided with a snap-fit ​​edge 243. The snap-fit ​​edge 243 and the light-transmitting window 23 are spaced apart, and the snap-fit ​​edge 243 and the light-transmitting window 23 form a snap-fit ​​groove 241. The edge of the watch screen protection panel 400 is embedded in the snap-fit ​​groove 241, and the waterproof ring 300 is located outside the snap-fit ​​groove 241.

[0047] The light-transmitting window 23 and the light-transmitting opening 24 are connected, and the light-transmitting window 23 and the light-transmitting opening 24 penetrate the housing 20 in the direction from the front 21 to the back 22. The watch screen protection panel 400 and the waterproof ring 300 can enter the light-transmitting opening 24 through the opening on the side of the light-transmitting opening 24 away from the light-transmitting window 23. Continuing to push the watch screen protection panel 400 and the waterproof ring 300 in the direction from the back 22 to the front 21, the edge of the watch screen protection panel 400 is embedded and fixed in the snap-fit ​​groove 241. At this time, the watch body 5 is installed in the light-transmitting opening 24 through the opening on the side of the light-transmitting opening 24 away from the light-transmitting window 23, and the watch screen 51 abuts against the second ring 320 of the waterproof ring 300. The waterproof ring 300 is sandwiched between the watch screen protection panel 400 and the watch screen 51, and the second ring 320 is circumferentially fitted to the watch screen 51. When external pressure is applied to the watch screen protection panel 400 and the watch body 5, such as... Figure 6 and Figure 7 As shown, the waterproof ring 300 is compressed along its axial direction, causing the second ring 320 to deform and accumulate elastic force. The angle between the second ring 320 and the first ring 310 decreases, the contact force between the second ring 320 and the watch screen 51 increases, and the contact area between the second ring 320 and the watch screen 51 increases.

[0048] It should be noted that, since the light-transmitting window 23 is an open structure, the watch screen protection panel 400 and the waterproof ring 300 can also enter the light-transmitting opening 24 through the light-transmitting window 23. For example, the inner side of the protruding edge 242 is provided with a slope or curved surface that is inclined in the direction from the front 21 to the back 22. The edge of the watch screen protection panel 400 slides along the slope or curved surface on the protruding edge 242 and is embedded in the snap-fit ​​groove 241, so that the watch screen protection panel 400 and the waterproof ring 300 are fixedly connected to the housing 20.

[0049] refer to Figure 8 and Figure 9The buckle edge 243 is provided with a guide surface 2431. The watch screen protection panel 400 can slide into the latching groove 241 along the guide surface 2431. In the direction from the back side 22 to the front side 21, the guide surface 2431 extends obliquely from the side of the buckle edge 243 away from the convex edge 242 to the side facing the convex edge 242. During the extension process, the distance from the guide surface 2431 to the center of the light-transmitting opening 24 gradually decreases. The guide surface 2431 is curved. After the watch screen protection panel 400 and the waterproof ring 300 enter the light-transmitting opening 24, the watch screen protection panel 400 is pushed in the direction from the back side 22 to the front side 21. The edge and guide surface 2431 abut against each other, and at least one of the edge of the watch screen protection panel 400 and the buckle edge 243 deforms, so that the watch screen protection panel 400 slides from the side of the buckle edge 243 away from the protruding edge 242 into the snap-fit ​​groove 241. The buckle edge 243 and the protruding edge 242 limit the watch screen protection panel 400 in the snap-fit ​​groove 241, so that the watch screen protection panel 400 can be easily and quickly connected to the housing 20. The waterproof ring 300 is located outside the snap-fit ​​groove 241. The buckle edge 243 can be made of rubber or other materials so that the edge of the watch screen protection panel 400 is not easily damaged during the snap-fit ​​process into the snap-fit ​​groove 241.

[0050] The width of the snap-fit ​​edge 243 is smaller than the width of the protruding edge 242. Both widths are the lengths extending from the inner wall of the light-transmitting opening 24 towards the center of the light-transmitting opening 24. This is to prevent excessive force from causing the watch screen protection panel 400 to slide excessively over the protruding edge 242 and detach from the housing 20 after the edge of the watch screen protection panel 400 is inserted into the snap-fit ​​groove 241 in the direction from the back 22 to the front 21.

[0051] Multiple snap-fit ​​edges 243 are provided, and the multiple snap-fit ​​edges 243 are circumferentially spaced on the inner wall of the light-transmitting opening 24. In this embodiment, the multiple snap-fit ​​edges 243 are arranged in pairs opposite each other along the circumferential direction of the inner wall of the light-transmitting opening 24, so that the guide surfaces 2431 on the snap-fit ​​edges 243 are also arranged in pairs. When the watch screen protection panel 400 abuts against the guide surfaces 2431, the pressing force generated by the guide surfaces 2431 on the watch screen protection panel 400 is decomposed into two: one force is along the direction from the front side 21 to the back side 22, and the other force is directed towards the watch screen protection panel 400. At the center, the forces generated by the two opposing guide surfaces 2431 toward the center of the watch screen protector panel 400 are directed in opposite directions, so that the watch screen protector panel 400 is subjected to uniform force. It should be noted that in other embodiments, the snap-fit ​​edge 243 can also be a circumferentially closed annular structure, with the axis of the snap-fit ​​edge 243 overlapping with the axis of the light-transmitting opening 24. The guide surface 2431 is also circumferentially closed along the snap-fit ​​edge 243. During the process of the watch screen protector panel 400 being inserted into the snap-fit ​​groove 241, every part of the circumferential edge of the watch screen protector panel 400 abuts against the guide surface 2431.

[0052] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
