[0029] At present, with the rapid development of the wearable smart device industry, watches, as a relatively popular wearable device, have great development potential. For smart watches, given their intelligence, their functions have been extended in the fields of smart communication, sports detection, etc. In order to adapt to a wider range of usage scenarios, the waterproof performance of watches is also gradually improving. However, at this stage, the waterproof performance of one side of the watch is mainly maintained by fixing the screen with double-sided tape or spot gluing, or using PET sheets on the side for interference fit waterproofing and ensuring its waterproof performance. The other side relies on a sealing ring and a watch cover for waterproofing. The existing waterproofing on the screen side is at risk of failure.

[0030] The inventor has discovered through research that existing watches rely on a glue dispensing process for waterproofing. When this process fails, water will directly flow into the cavity where the electronic control module is located, causing circuit device failures.

[0031] In view of this, the present invention proposes a watch, aiming to improve the waterproof performance of the watch.

[0032] See also Figure 1 and Figure 2 In one embodiment of the present invention, the watch 100 includes a watch case 1, a watch cover 2, a display module 3 and a touch screen 4 covering the display module 3. The watch cover 2 is arranged on one side of the watch case 1, and the side wall of the watch case 1 away from the watch cover 2 bulges inward to form a protrusion 11. The watch 100 includes a first sealing ring 5 and an annular sealing member 6 arranged on the watch case 1. The first sealing ring 5 is located on the side of the protrusion 11 facing the watch cover 2, and the side of the first sealing ring 5 facing the watch cover 2 abuts against the side of the touch screen 4 away from the watch cover 2. The annular sealing member 6 is arranged in the watch case 1 and extends along the circumference of the watch case 1. The top surface of the annular sealing member 6 abuts against the side of the touch screen 4 facing the watch cover 2, so that the annular sealing member 6, the watch case 1, the first sealing ring 5 and the touch screen 4 enclose a waterproof space 7.

[0033] The technical solution of the present invention constructs a first waterproof barrier by abutting one side of the first sealing ring 5 with the protrusion 11 and the other side of the first sealing ring 5 with the touch screen 4, thereby improving the waterproof performance of the watch 100; by adding an annular seal 6 and the inner wall of the case 1, the first sealing ring 5 and the touch screen 4 to form a waterproof space 7, a second waterproof barrier is constructed, so that even if water passes through the first sealing ring 5, the water passing through will be sealed in the waterproof space 7 and will not flow to the cavity where the display module 3 is located. The water is temporarily stored in the waterproof space 7, making it difficult for the external water pressure to act on the annular seal 6 in a short time, thereby effectively increasing the immersion time of the watch 100 and further improving the waterproof performance of the watch 100; even if the waterproof space 7 is filled with water, it is difficult for the water to flow out of the waterproof space 7, thereby providing a reliable guarantee for the watch 100 to have good waterproof performance. It should be noted that, since the first sealing ring 5 and the annular seal 6 are arranged below the raised portion 11, it is difficult for sunlight to irradiate the first sealing ring 5 and the annular seal 6, thereby effectively reducing the degradation rate of the first sealing ring 5 and the annular seal 6, extending the service life of the first sealing ring 5 and the annular seal 6, making the first sealing ring 5 and the annular seal 6 less likely to fail, and improving the waterproof reliability of the watch 100. It should also be noted that the watch case 1 is made of waterproof material, and the shape of the raised portion 11 can be rectangular or stepped, which is not limited here.

[0034] In addition, the inventors have also found that the screen of the existing watch 100 is easily broken when it falls.

[0035] The technical solution of the present invention is to respectively provide a first sealing ring 5 and an annular sealing member 6 on the upper and lower sides of the touch screen 4 to abut against the touch screen 4. The first sealing ring 5 and the annular sealing member 6 are both made of elastic or flexible materials, so that they can play a certain buffering role on the touch screen 4 when the watch 100 falls, thereby reducing the probability of the screen being broken.

[0036] According to one embodiment of the present invention, an adhesive portion is provided on one side of the contact point between the annular seal 6 and the touch screen 4 close to the inside of the watch case 1, and the adhesive portion extends along the circumference of the watch case 1, thereby improving the connection strength between the annular seal 6 and the touch screen 4, making it difficult for water in the waterproof space 7 to enter the cavity in the watch case 1 outside the waterproof space 7.

[0037] See also Figure 1 and Figure 3In one embodiment, a drainage channel 13 is formed on the side wall of the watch case 1, and a drainage hole 14 is provided on the outer wall of the watch case 1. One end of the drainage channel 13 is connected to the waterproof space 7, and the other end of the drainage channel 13 is connected to the drainage hole 14. The watch 100 also includes a plugging member 8, one end of which is provided in the drainage hole 14 to prevent fluid from entering the drainage channel 13 from outside the drainage hole 14. If liquid is stored in the waterproof space 7, the liquid may corrode the annular seal 6 if it stays in the waterproof space 7 for a long time, thereby reducing the life of the annular seal 6. In this embodiment, by providing the drainage channel 13 and the drainage hole 14, when it is necessary to drain the water in the waterproof space 7, the plugging member 8 can be moved out of the drainage hole 14, and then the drainage hole 14 can be downward, so that the water can flow through the drainage channel 13 under the action of gravity and then flow out from the drainage hole 14; after the drainage is completed, the drainage hole 14 is blocked by the plugging member 8, thereby reducing the probability of external water entering the waterproof space 7 through the drainage hole 14. It should be noted that the blocking member 8 is made of waterproof material and can be a screw.

[0038] According to one embodiment of the present invention, the inner wall of the watch case 1 is provided with a housing cavity for accommodating the blocking member 8, and the housing cavity is communicated with the drainage hole 14. The watch 100 also includes a driving member, and the driving member is in transmission connection with the blocking member 8, so that the driving member can drive the blocking member 8 to block the drainage hole 14, or release the blockage of the drainage hole 14. It should be noted that when the blocking member 8 is in the housing cavity, the blocking member 8 will not block the drainage hole 14 or partially block the drainage hole 14. It should also be noted that the driving member can be a small electric push rod or a micro motor, etc., the telescopic shaft of the small electric push rod can be directly connected to the blocking member 8 and drive the blocking member 8 to move, and the micro motor can be connected to the blocking member 8 through a gear rack structure or a screw structure, etc., so as to drive the blocking member 8 to move.

[0039] In one embodiment, the drainage channel 13 is arranged in a tortuous manner. The drainage channel 13 is arranged in a tortuous S shape, so that even if water enters the drainage channel 13 through the gap between the drainage hole 14 and the blocking member 8, it is not easy for the water to flow into the waterproof space 7 through the tortuous drainage channel 13, thereby reducing the probability of water entering the cavity where the display module 3 is located from the waterproof space 7. The drainage channel 13 can also be a linear channel.

[0040] In one embodiment, the drainage channel 13 includes a plurality of first curved segments 131 and a plurality of second curved segments 132, the first curved segments 131 and the second curved segments 132 are alternately arranged in sequence along the radial direction of the watch case 1, any adjacent first curved segments 131 and second curved segments 132 are connected to each other, and the first curved segments 131 and the second curved segments 132 are arranged at intervals along the axial direction of the watch case 1; the first curved segment 131 or the second curved segment 132 arranged near the inner wall of the watch case 1 is connected to the drainage channel 13, and the first curved segment 131 or the second curved segment 132 arranged near the outer wall of the watch case 1 is connected to the drainage hole 14. By setting a plurality of first curved segments 131 and second curved segments 132, it is difficult for water to flow into the waterproof space 7 through the tortuous drainage channel 13, thereby reducing the probability of water entering the cavity where the display module 3 is located from the waterproof space 7. It should be noted that when a drainage operation is required, the user only needs to add a shake along the axial direction of the watch case 1 on the basis of the original drainage operation to smoothly make the water flow through the drainage channel 13 and then flow out from the drainage hole 14. It should also be noted that the axial direction of the watch case 1 is Figure 1 In the up and down direction shown, the radial direction of the case 1 is Figure 1 It should be further explained that the drainage channel 13 of the present embodiment is a longitudinally bent S-shaped arrangement, and in addition, the drainage channel can also be a transversely bent S-shaped arrangement, or a combination of the two.

[0041] In one embodiment, the sealing member 8 includes an insertion portion 81 and an abutment portion 82 that are interconnected; the inner wall of the drain hole 14 is provided with an internal thread, the outer surface of the insertion portion 81 is provided with an external thread that can be spirally matched with the internal thread, and the abutment portion 82 is close to the insertion portion 81. The side of the abutment portion 82 is in contact with the outer wall of the watch case 1; the abutment portion 82 is in contact with the watch case 1, thereby reducing the probability of water entering the drain hole 14 when the sealing member 8 blocks the drain hole 14; the insertion portion 81 is provided with an external thread that is spirally matched with the internal thread of the through hole 12, which can effectively reduce the probability of water entering the drainage channel 13 through the drain hole 14 when the sealing member 8 blocks the drain hole 14, so that the watch 100 has both drainage function and good waterproof ability.

[0042] In one embodiment, the plugging member 8 includes an inserting portion 81 and an abutting portion 82 connected to each other; the plugging member 8 is an elastic plugging member 8, and the outer diameter of the inserting portion 81 is larger than the inner diameter of the drain hole 14, so that the inserting portion 81 can be interference-fitted with the drain hole 14, and the abutting portion 82 is in contact with the outer wall of the watch case 1 on one side close to the inserting portion 81. The abutting portion 82 is in contact with the watch case 1, thereby reducing the probability of water entering the drain hole 14 when the plugging member 8 blocks the drain hole 14; the inserting portion 81 is interference-fitted with the through hole 12, which can effectively reduce the probability of water entering the drain channel 13 through the drain hole 14 when the plugging member 8 blocks the drain hole 14.

[0043] In one embodiment, the first sealing ring 5 is injection molded on the watch case 1. By injection molding the first sealing ring 5 on the watch case 1, the assembly process of the first sealing ring 5 is omitted, the production efficiency of the watch 100 is improved, and the production cost of the watch 100 is reduced; by reasonably designing the shape of the first sealing ring 5 and injecting it on the watch case 1, the structural design of the first sealing ring 5 is simplified; at the same time, it also avoids the phenomenon that the waterproof performance of the watch 100 is affected due to the first sealing ring 5 not being installed in place due to manual installation, thereby improving the yield rate of the watch 100.

[0044] In one embodiment, the annular seal 6 is injection molded on the watch case 1. By injection molding the annular seal 6 on the watch case 1, the assembly process of the annular seal 6 is omitted, the production efficiency of the watch 100 is improved, and the production cost of the watch 100 is reduced; by reasonably designing the shape of the annular seal 6 and injecting it on the watch case 1, the structural design of the annular seal 6 is simplified; at the same time, it also avoids the phenomenon that the waterproof performance of the watch 100 is affected due to the annular seal 6 not being installed in place due to manual installation, thereby improving the yield rate of the watch 100.

[0045] In one embodiment, a contact area 41 and a raised area are provided on the side of the touch screen 4 away from the watch cover 2, the contact area 41 is arranged around the raised area, the raised area is raised in a direction away from the watch cover 2 to form a protruding portion 42, and the raised portion 11 surrounds a through hole 12 for accommodating the protruding portion 42. The protruding portion 42 is formed on the raised area of ​​the touch screen 4, so that the side of the touch screen 4 away from the watch cover 2 is arranged in a stepped manner, the protruding portion 42 is located in the through hole 12, and the protruding portion 42 is positioned by relying on the through hole 12 to prevent the protruding portion 42 from being displaced significantly compared to the watch case 1, which affects the user experience and the aesthetic appearance of the product.

[0046] In one embodiment, the watch 100 further includes a second sealing ring 9, which is injection molded on the inner wall of the through hole 12, the inner side of the second sealing ring 9 abuts against the outer wall of the extension 42, and the second sealing ring 9 is arranged around the extension 42. By arranging the second sealing ring 9 around the extension 42 on the inner wall of the through hole 12, not only the waterproof performance of the watch 100 is improved, but also the extension 42 is limited from being displaced greatly relative to the watch case 1, which affects the user experience and the aesthetic appearance of the product.

[0047] In one embodiment, the watch 100 further includes a circuit module 10 and an elastic member 20. The circuit module 10 is disposed in the watch case 1 and is spaced apart from the display module 3. The elastic member 20 is located between the circuit module 10 and the display module 3. One side of the elastic member 20 abuts against the circuit module 10, and the other side of the elastic member 20 abuts against the display module 3. By arranging the elastic member 20 to connect the display module 3 and the circuit module 10 respectively, when the watch 100 falls, the vibration of the touch screen 4 will be transmitted to the elastic member 20 through the display module 3 and buffered by the elastic member 20, thereby effectively reducing the probability of the touch screen 4 being broken.

[0048] According to an embodiment of the present invention, the watch 100 further includes a separator 50, which is disposed in the watch case 1 and the side wall of the separator 50 is sealed and connected to the inner wall of the watch case 1. The separator 50 divides the space inside the watch case 1 into a first space 15 and a second space 16 which are independent of each other. The first space 15 and the second space 16 are arranged along the axial direction of the watch case 1. Part of the structure of the touch screen 4, the display module 3, the elastic member 20, the circuit module 10, the annular seal 6, the first seal ring 5 and the second seal ring 9 are located in the first space 15. The watch cover 2, the watch case 1 and the separator 50 form a closed second space 16, which prevents water from flowing into the watch case 1 from the gap between the watch cover 2 and the watch case 1 and can directly flow into the first space 15, thereby improving the waterproof performance of the watch 100. It should be noted that one side of the separator 50 abuts against the watch cover 2, and the other side of the separator 50 abuts against the circuit module 10, so that the separator 50 can provide reliable support for the circuit module 10. It should also be noted that the side wall of the separator 50 may be fitted with the inner wall of the watch case 1 to achieve a sealed connection, or the inner wall of the watch case 1 may be injection-molded with a plurality of annular sealing rings, the inner side of the annular sealing rings abutting against the side wall of the separator 50 to achieve a sealed connection, or the inner wall of the watch case 1 may be provided with an internal thread, the side wall of the separator 50 may be provided with an external thread, and the separator 50 may be screwed together with the watch case 1. It should be noted that the circuit module 10 may also be directly connected to the watch case 1.

[0049] In one embodiment, the side of the raised portion 11 away from the watch cover 2 is raised in a direction away from the watch cover 2 to form a protective portion 111, and the distance from the side of the protective portion 111 away from the watch cover 2 to the watch cover 2 is greater than the distance from the side of the touch screen 4 away from the watch cover 2 to the watch cover 2. By providing the protective portion 111, for a foreign object with a planar structure, the protective portion 111 will contact the foreign object before the touch screen 4, avoiding the touch screen 4 from directly contacting and colliding with the foreign object, thereby reducing the probability of the touch screen 4 being broken when the watch 100 collides with the foreign object.

[0050] In one embodiment, the annular seal 6 comprises a connecting portion 61, a bending portion 62 and a sealing portion 63 connected in sequence, the end of the connecting portion 61 away from the bending portion 62 is arranged on the inner wall of the watch case 1, the bending portion 62 and the sealing portion 63 are arranged at intervals from the inner wall of the watch case 1, the sealing portion 63 abuts against the side of the touch screen 4 facing the watch cover 2, the bending portion 62 bends toward the inside of the watch case 1, and the side of the bending portion 62 away from the watch case 1 abuts against the side wall of the display module 3. The bending portion 62 is bent inwardly, so that the volume of the waterproof space 7 is larger, and the top surface of the abutting portion 82 abuts against the bottom surface of the touch screen 4, and the inner side surface of the bending portion 62 abuts against the display module 3, so that the abutting portion 82, the bending portion 62, the touch screen 4 and the display module 3 enclose a cavity approximately in a triangular shape. Due to the stability of the triangle itself, the pressure bearing capacity of the annular seal 6 is stronger, and the water in the waterproof space 7 is less likely to flow out of the waterproof space 7, which effectively improves the waterproof performance of the watch 100. It should be noted that the annular seal 6 is made of waterproof material, the connecting portion 61 is annular, the inner side of the connecting portion 61 is connected to the bending portion 62 , and the outer side of the connecting portion 61 is connected to the inner wall of the watch case 1 .

[0051] See also Figure 1 and Figure 4 In one embodiment, the watch 100 further includes a third sealing ring 30, which is injection molded on the side of the watch case 1 facing the watch cover 2, and extends along the circumference of the watch case 1.
