[0052] Refer to the accompanying drawings of the specification of this utility model application. Figures 1 to 26 A preferred embodiment of the present invention, a wrist-worn diving watch, will be disclosed and described below. The wrist-worn diving watch includes a watch body 10 and a wristband 20, the wristband 20 being disposed on the watch body 10, allowing the diver to wear the watch body 10 on their wrist. Specifically, the watch body 10 includes a main housing 11, a circuit board assembly 12, at least one button assembly 13, a display assembly 14, and a top cover 15. The circuit board assembly 12, the button assembly 13, the display assembly 14, the top cover 15, and the wristband 20 are respectively disposed on the main housing 11.

[0053] Specifically, see the attached document. Figure 1 , Figure 9 and Figure 26The main housing 11 has a receiving cavity 111 and at least one main housing through hole 112, the main housing through hole 112 communicating with the receiving cavity 111, wherein the circuit board assembly 12 is disposed in the receiving cavity 111 of the main housing 11.

[0054] Reference Appendix Figure 9 , Figure 21 and Figure 22 The circuit board assembly 12 includes a main board 121, at least one switch board 122, at least one switch 123, and at least one switch bracket 124. The main board 121 is locked to the main housing 11, the switch 123 is mounted on the switch board 122, the switch board 122 is mounted on the switch bracket 124, the switch bracket 124 is mounted on the main housing 11, the switch board 122 is soldered to the main board 121, and the position of the switch 123 corresponds to the position of the main housing through hole 112 of the main housing 11.

[0055] In this specific example of the wrist-worn diving watch of this utility model, the main board 121 can be locked to the main housing 11 by a set of screws 100, and the switch bracket 124 can also be locked to the main housing 11 by a set of screws 100.

[0056] To facilitate soldering the switch board 122 and the main board 121, the main board 121 has at least one pair of mounting holes 1211, and the switch board 122 has a pair of pins 1221. After the pair of pins 1221 of the switch board 122 are respectively inserted into the pair of mounting holes 1211 of the main board 121, the pins 1221 of the switch board 122 and the main board 121 are soldered together, so that the switch board 122 is soldered to the main board 121 and the switch board 122 and the main board 121 are electrically connected.

[0057] Reference Appendix Figure 21 and Figure 22The switch bracket 124 has a bracket groove 1241 and two slots 1242. Each of the bracket groove 1241 has a slot 1242 on its opposite sides. The switch plate 122 is received in the bracket groove 1241 of the switch bracket 124, and the opposite sides of the switch plate 122 are respectively snapped into the two slots 1242 of the switch bracket 124. In this way, the switch plate 122 can be reliably installed on the switch bracket 124. When the switch 123 is pressed, causing the switch plate 122 to be subjected to force, the relative position of the switch plate 122 and the switch bracket 124 remains unchanged. Meanwhile, since the switch bracket 124 is locked to the main housing 11, when the switch 123 is pressed and the switch plate 122 is subjected to force, the relative position of the switch plate 122 and the main housing 11 remains unchanged. This helps to ensure the reliability of the conductive relationship between the switch plate 122 and the main board 121, thereby ensuring the reliability and stability of the wrist-worn diving watch.

[0058] Preferably, refer to the appendix Figure 25 The main housing 11 has at least one recessed groove 113 extending downward from the receiving cavity 111. The bottom of the switch bracket 124 is recessed into the recessed groove 113 of the main housing 11. In this way, on the one hand, when assembling the wrist-worn diving watch, the recessed groove 113 of the main housing 11 can be used to position the switch bracket 124, ensuring that the switch bracket 124 is installed in the designed position so that a pair of pins 1221 of the switch plate 122 can be inserted into a pair of mounting holes 1211 of the main plate 121 respectively. On the other hand, when the wrist-worn diving watch is used, the main housing 11 can prevent the bottom of the switch bracket 124 from sliding relative to the main housing 11, thereby ensuring that the switch bracket 124 is reliably installed on the main housing 11 and guaranteeing the reliability and stability of the wrist-worn diving watch.

[0059] More preferably, continue to refer to the appendix. Figure 25 The main housing 11 has a pair of limiting grooves 114 extending downward from the recessed groove 113. The switch bracket 124 has a pair of limiting protrusions 1243, which are respectively inserted into the pair of limiting grooves 114 of the main housing 11. When assembling the wrist-worn diving watch, the limiting protrusions 1243 of the switch bracket 124 and the limiting grooves 114 of the main housing 11 cooperate with each other to limit the installation position of the switch bracket 124.

[0060] Continue to refer to the appendix Figure 25To facilitate locking the switch bracket 124 to the main housing 11, in this specific example of the wrist-worn diving watch of the present invention, the main housing 11 has at least one pair of support arms 115, and the top of the switch bracket 124 has a pair of abutment arms 1244. After the bottom of the switch bracket 124 sinks into the recessed groove 113 of the main housing 11 and the limiting protrusion 1243 of the switch bracket 124 is inserted into the limiting groove 114 of the main housing 11, the abutment arms 1244 of the switch bracket 124 abut against the support arms 115 of the main housing 11. The screw 100 can be used to lock the abutment arms 1244 of the switch bracket 124 to the support arms 115 of the main housing 11.

[0061] It is understood that, since the bottom of the switch bracket 124 is sunken into the recessed groove 113 of the main housing 11 and the limiting protrusion 1243 of the switch bracket 124 is inserted into the limiting groove 114 of the main housing 11, and the supporting arm 1244 at the top of the switch bracket 124 is locked to the support arm 115 of the main housing 11, when the switch 123 is pressed and the switch plate 122 is subjected to force, the switch bracket 124 can ensure the stability of the position of the switch plate 122 and the switch 123, and prevent the switch plate 122 and the switch 123 from tilting, thereby ensuring the reliability and stability of the wrist-worn diving watch.

[0062] Reference Appendix Figure 23 , Figure 24 and Figure 26 The button assembly 13 includes a button 131, a spring 132, and an inner retaining ring 133. The button 131 includes a button cap 1311 and a push rod 1312. The button cap 1311 and the push rod 1312 are integral, that is, the push rod 1312 extends outward integrally from the button cap 1311, and the inner end of the push rod 1312 extends through the main housing through hole 112 of the main housing 11 to the receiving cavity 11. 1. The spring 132 is fitted onto the push rod 1312, the outer end of the spring 132 abuts against the button cap 1311, the inner end of the spring 132 remains stationary relative to the main housing 11, and the inner retaining spring 133 is snapped into the inner end of the push rod 1312 to prevent the push rod 1312 from falling out of the main housing through hole 112 of the main housing 11, so that the button assembly 13 is pressably mounted on the main housing 11.

[0063] Since the position of the switch 123 on the circuit board assembly 12 corresponds to the position of the main housing through-hole 112 on the main housing 11, the position of the inner end of the push rod 1312 corresponds to the position of the switch 123. When the diver presses the button cap 1311 of the button 131, the push rod 1312 moves relative to the main housing 11 and applies pressure to the switch 123 to change the working state of the wrist-worn diving watch. At the same time, the button cap 1311 compresses the spring 132 towards the main housing 11, causing the spring 132 to compress and deform to accumulate elastic potential energy. After the diver releases the button cap 1311 of the button 131, the spring 132 pushes the button cap 1311 outward during the process of returning to its initial state, causing the inner end of the push rod 1312 to move away from the switch 123.

[0064] Understandably, since the bottom of the switch bracket 124 is sunken into the recessed groove 113 of the main housing 11 and the limiting protrusion 1243 of the switch bracket 124 is inserted into the limiting groove 114 of the main housing 11, and the supporting arm 1244 at the top of the switch bracket 124 is locked to the support arm 115 of the main housing 11, when the diver presses the button cap 1311 of the button 131, causing the push rod 1312 to apply pressure to the switch 123, the switch bracket 124 can ensure the stability of the switch plate 122 and the switch 123, preventing the switch plate 122 and the switch 123 from tilting, thereby ensuring the reliability and stability of the wrist-worn diving watch.

[0065] Preferably, in this specific example of the wrist-worn diving watch of this utility model, the button 131 and the spring 132 can be integrated. For example, the button 131 and the spring 132 can be integrally molded from plastic material using an injection molding process. In this way, not only is it convenient to assemble the wrist-worn diving watch, but the spring 132 can also have good corrosion resistance, which is beneficial to extending the life of the wrist-worn diving watch.

[0066] Further, please refer to the appendix. Figures 1 to 6 , Figure 26The main housing 11 has at least one mounting cavity 116, which communicates with the main housing through hole 112. The button assembly 13 further includes at least one sealing ring 134, which is fitted into the mounting cavity 116 of the main housing 11 and sleeved on the push rod 1312 of the button 131. The main housing 11 and the push rod 1312 clamp the sealing ring 134, causing it to deform. In this way, on the one hand, the sealing ring 134 allows the push rod 1312 to reciprocate, and on the other hand, the sealing ring 134 prevents water from entering the mounting position of the main housing 11 and the button assembly 13, thereby preventing water from entering the receiving cavity 111 of the main housing 11 and ensuring the watertightness of the wrist-worn diving watch. Preferably, there are two sealing rings 134. The two sealing rings 134 cooperate with each other, which not only allows the push rod 1312 to reciprocate relative to the main housing 11, but also provides better sealing.

[0067] Furthermore, please refer to the appendix. Figure 23 , Figure 24 and Figure 26 The button assembly 13 includes a blocking plate 135 and an outer retaining spring 136. The blocking plate 135 has a one-piece through hole 1351. The inner diameter of the blocking plate 135 is smaller than the outer diameter of the sealing ring 134. The blocking plate 135 is disposed at the opening of the assembly cavity 116 of the main housing 11. The outer retaining spring 136 is snapped into the main housing 11 and fits against the blocking plate 135. In this way, the outer retaining spring 136 can ensure that the blocking plate 135... 35 is reliably positioned at the opening of the assembly cavity 116 of the main housing 11, and since the inner diameter of the shield 135 is smaller than the outer diameter of the sealing ring 134, when the push rod 1312 of the button 131 moves, the shield 135 can prevent the sealing ring 134 from disengaging from the assembly cavity 116 of the main housing 11, thereby ensuring the watertightness of the assembly position of the main housing 11 and the button assembly 13.

[0068] In the appendix Figures 1 to 26 In a specific example of the wrist-worn diving watch of the present invention shown, the inner end of the spring 132 abuts against the shield 135, such that the inner end of the spring 132 is configured to remain stationary relative to the main housing 11.

[0069] Furthermore, the main housing 11 has at least one receiving groove 117, which communicates with the assembly cavity 116. The spring 132, the outer retaining ring 136, and the shielding plate 135 are all received in the receiving groove 117 of the main housing 11. The button cap 1311 of the button 131 covers the receiving groove 117 of the main housing 11. In this way, the spring 132 can be hidden between the main housing 11 and the button cap 1311 to prevent foreign objects from entering the gap of the spring 132 and causing the spring 132 to fail, thereby ensuring the reliability and stability of the wrist-worn diving watch. Optionally, in other examples of the wrist-worn diving watch of this utility model, the periphery of the button cap 1311 of the button 131 can extend to the receiving groove 117 of the main housing 11. In this way, the spring 132 can be hidden between the main housing 11 and the button cap 1311 to prevent foreign objects from entering the gap of the spring 132 and causing the spring 132 to fail, thereby ensuring the reliability and stability of the wrist-worn diving watch.

[0070] Reference Appendix Figure 21 , Figure 22 , Figure 25 and Figure 26 The display assembly 14 includes a screen bracket 141, a display screen 142, and a tempered glass 143. The display screen 142 is mounted on the screen bracket 141. For example, adhesive can be used to bond the display screen 142 to the screen bracket 141 to mount the display screen 142 to the screen bracket 141. The screen bracket 141 is mounted on the main housing 11. For example, a set of screws 100 can be used to lock the screen bracket 141 to the main housing 11, and the screen bracket 141 and the display screen 142 are located at... The tempered glass 143 is placed around the edge of the cavity 111 of the main housing 11, with its periphery resting against the edge of the cavity opening. The tempered glass 143 seals the cavity opening of the main housing 11, and the display screen 142 corresponds to the center of the tempered glass 143. In this way, the tempered glass 143 can prevent water from entering the cavity 111 of the main housing 11 and protect the display screen 142, while the content displayed on the display screen 142 can be seen through the tempered glass 143.

[0071] Furthermore, the display assembly 14 includes a deformable isolation pad 144, which may be, but is not limited to, black foam. The inner side of the isolation pad 144 is clamped between the display screen 142 and the tempered glass 143, and the outer side of the isolation pad 144 is clamped between the screen bracket 141 and the tempered glass 143. The isolation pad 144 is used to provide a cushioning function to protect the display screen 142.

[0072] The top cover 15 has a top cover through-hole 151. The top cover 15 is mounted to the main housing 11 by pressing against the edge of the tempered glass 143, and the top cover through-hole 151 of the top cover 15 corresponds to the center of the tempered glass 143, thus allowing the top cover 15 to reliably position the tempered glass 143 on the main housing 11. In this specific example of the wrist-worn diving watch of this invention, a set of screws 100 can be used to reliably mount the top cover 15 to the main housing 11.

[0073] Preferably, the diving watch body 10 further includes a sealing gasket 16, which is sandwiched between the main housing 11 and the tempered glass 143, and surrounds the opening of the receiving cavity 111. The sealing gasket 16 is used to prevent water from entering at the assembly position of the main housing 11 and the tempered glass 143, thereby ensuring the watertightness of the wrist-worn diving watch. Specifically, the main housing 11 has a groove 118 surrounding the opening of the receiving cavity 111 of the main housing 11. The thickness of the sealing gasket 16 is greater than the depth of the groove 118 of the main housing 11. After the bottom of the sealing gasket 16 is installed in the groove 118 of the main housing 11, the top of the sealing gasket 16 protrudes from the main housing 11. Thus, after the periphery of the tempered glass 143 rests against the edge of the opening of the receiving cavity 111 of the main housing 11 and the top cover 15 is installed on the main housing 11 in such a way as to press against the edge of the tempered glass 143, the main housing 11 and the tempered glass 143 squeeze and deform the sealing gasket 16. The sealing gasket 16 prevents water from entering the assembly position of the main housing 11 and the tempered glass 143, thereby ensuring the watertightness of the wrist-worn diving watch.

[0074] The main housing 11 has a concave bottom surface 119, the shape of which matches the shape of the diver's wrist. After the diver wears the wrist-worn diving watch on his wrist, the bottom surface 119 of the main housing 11 fits snugly against the diver's wrist to improve comfort.

[0075] The main housing 11 further has a pair of strap holes 1110, and each of the bottom surfaces 119 has a strap hole 1110 on one of its opposite sides. One end of the wrist strap 20 passes through the two strap holes 1110 of the main housing 11 in sequence to attach the wrist strap 20 to the diving watch body 10, allowing the diver to wear the diving watch body 10 on their wrist. Specifically, the opposite ends of the wrist strap 20 may be provided with Velcro.

[0076] The main housing 11 further has a plug through hole 1111, which is connected to the receiving cavity 111. The diving watch body 10 further includes a watertight cable assembly 17, which includes a watertight cable 171 and a nut 172. The watertight cable 171 includes a first plug 1711, a second plug 1712, and a cable body 1713. The cable body 1713 extends between the first plug 1711 and the second plug 1712. After the first plug 1711 extends through the plug through hole 1111 of the main housing 11 to the receiving cavity 111 of the main housing 11, the nut 172 is screwed into the receiving cavity 111 of the main housing 11. In this way, the assembly position of the main housing 11 and the watertight cable assembly 17 can have good watertightness, preventing water from entering the receiving cavity 111 of the main housing 11. The first plug 1711 is connected to the motherboard 121.

[0077] Further, see attached document. Figure 8 and Figure 9 The main body of the diving watch includes a magnetic compass 18 for providing positioning functionality, wherein the magnetic compass 18 is locked to the main housing 11 and located in the receiving cavity 111 of the main housing 11. Preferably, the main board 121 has a clearance groove 1212 for accommodating the magnetic compass 18. In this way, the wrist-worn diving watch can have a compact structure, which is beneficial for the miniaturization of the wrist-worn diving watch.

[0078] In this specific example of the wrist-worn diving watch of this utility model, the main body 10 of the diving watch is generally rectangular. Two main housing through-holes 112, two assembly cavities 116, and two receiving slots 117 are respectively provided on opposite sides of the main housing 11. A plug through-hole 1111 is provided at one end of the main housing 11. The circuit board assembly 12 consists of four switch plates 122, four switches 123, and four switch brackets 124.

Preferably, the outer diameter of the sealing ring 134 is slightly larger than the assembly cavity 116 of the main housing 11, so that after the sealing ring 134 is installed in the assembly cavity 116 of the main housing 11, the main housing 11 can slightly compress the sealing ring 134, causing the sealing ring 134 to deform slightly. In the wrist-worn diving watch of this utility model, when the outer diameter of the sealing ring 134 is slightly larger than the inner diameter of the assembly cavity 116 of the main housing 11, in order to facilitate the installation of the sealing ring 134 in the assembly cavity 116 of the main housing 11, the main housing 11 is provided with a housing chamfer 1112 at the opening of the assembly cavity 116 to guide the sealing ring 134 into the assembly cavity 116.

[0081] Reference Appendix Figure 3The shielding plate 135 is positioned at the opening of the assembly cavity 116 of the main housing 11. Since the inner diameter of the shielding plate 135 is smaller than the outer diameter of the sealing ring 134, the shielding plate 135 can prevent the sealing ring 134 from falling out of the assembly cavity 116 of the main housing 11.

[0082] Reference Appendix Figure 4 The outer retaining spring 136 is fitted onto the main housing 11, and the outer retaining spring 136 is abutted against the baffle plate 135, so that the baffle plate 135 can be reliably positioned at the opening of the assembly cavity 116 of the main housing 11. To reliably fit the outer retaining spring 136 onto the main housing 11, the main housing 11 has a retaining spring groove 1113 on the inner wall of the receiving groove 117, adjacent to the opening of the assembly cavity 116, and the outer edge of the outer retaining spring 136 engages with the retaining spring groove 1113 of the main housing 11.
