[0032] Refer to the accompanying drawings of the specification of this utility model application. Figures 1 to 8 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the diving computer includes a housing 10, a circuit board 20, at least one switch 30 and at least one button assembly 40.

[0033] The housing 10 has a watertight cavity 11, at least one assembly cavity 12, and at least one housing through hole 13, the housing through hole 13 connecting the watertight cavity 11 and the assembly cavity 12. The switch 30 is connected to the circuit board 20, the circuit board 20 and the switch 30 are respectively disposed in the watertight cavity 11 of the housing 10, the housing 10 provides a watertight environment for the circuit board 20 and the switch 30, wherein the position of the switch 30 corresponds to the position of the housing through hole 13 of the housing 10. The button assembly 40 includes at least one sealing ring 41, a blocking plate 42, a button 43, an inner retaining spring 44, and an elastic element 45. The sealing ring 41 is installed in the assembly cavity 12 of the housing 10. The blocking plate 42 has a one-piece through hole 421, and the inner diameter of the blocking plate 42 is smaller than the outer diameter of the sealing ring 41. The blocking plate 42 is configured to block the opening of the assembly cavity 12 of the housing 10 to prevent the sealing ring 41 from falling out of the assembly cavity 12 of the housing 10, thereby reliably retaining the sealing ring 41 in the assembly cavity 12 of the housing 10. 2. The key 43 includes a keycap 431 and a key lever 432 whose outer end is disposed on the keycap 431. The inner end of the key lever 432 extends to the watertight cavity 11 of the housing 10 after passing through the plate perforation 421 of the blocking plate 42, the sealing ring 41 and the housing perforation 13 of the housing 10 in sequence. The inner snap ring 44 is snapped into the inner end of the key lever 432 to prevent the key 43 from falling off the housing 10. The outer end of the elastic element 45 is configured to remain stationary relative to the keycap 431, and the inner end of the elastic element 45 abuts against the blocking plate 42.

[0034] When the keycap 431 is pressed, causing the key lever 432 to move relative to the housing 10, the inner end of the key lever 432 applies pressure to the switch 30, changing the state of the switch 30. During this process, the elastic element 45 is compressed and deformed to accumulate elastic potential energy. After the pressure applied to the keycap 431 is released, the elastic element 45 pushes the keycap 431 outward during the process of returning to its initial state, so that the position of the key 43 is reset.

[0035] In this specific example of the diving computer of this utility model, since the sealing ring 41 is clamped between the key stick 432 and the housing 10, the sealing ring 41 can effectively prevent water from entering the watertight cavity 11 of the housing 10 through the assembly position of the key assembly 40 and the housing 10. To further improve the watertight performance of the diving computer, the key assembly 40 includes two sealing rings 41, which are fitted adjacently to the key stick 432, and both sealing rings 41 are clamped between the key stick 432 and the housing 10.

[0036] In this specific example of the diving computer of this utility model, since the blocking plate 42 blocks the opening of the assembly cavity 12 of the housing 10, and the inner diameter of the blocking plate 42 is smaller than the outer diameter of the sealing ring 41, the blocking plate 42 can prevent the sealing ring 41 from detaching from the assembly cavity 12 of the housing 10 when the key rod 432 moves, so as to ensure that the sealing ring 41 effectively prevents water from entering the watertight cavity 11 of the housing 10 through the assembly position of the key assembly 40 and the housing 10.

[0037] Preferably, the outer end of the elastic element 45 abuts against the keycap 431, such that the outer end of the elastic element 45 is configured to remain stationary relative to the keycap 431. That is, in a specific example of the diving computer watch of this invention, the opposite ends of the elastic element 45 abut against the keycap 431 and the blocking plate 42, respectively. Thus, when the keycap 431 is pressed, causing the key lever 432 to move relative to the housing 10, the elastic element 45 is pressed against the blocking plate 42 by the keycap 431, causing the elastic element 45 to be compressed and deformed to accumulate elastic potential energy. After the pressure applied to the keycap 431 is released, the elastic element 45 pushes the keycap 431 outward during the process of returning to its initial state, thereby resetting the position of the button 43.

[0038] More preferably, the elastic element 45 is fitted onto the key stick 432. In this way, the key stick 432 can prevent the elastic element 45 from tilting, which helps to ensure that the opposite ends of the elastic element 45 always abut against the keycap 431 and the blocking piece 42.

[0039] Continue to refer to the appendix Figures 1 to 8The housing 10 is generally square, having a bottom side 101, a top side 102, two side sides 103, and two end sides 104. The bottom side 101 and the top side 102 are opposite each other, the two side sides 103 are opposite each other, and the two end sides 104 are opposite each other. The mounting cavity 12 of the housing 10 is located on the side side 103 of the housing 10, so the button assembly 40 is disposed on the side side 103 of the housing 10. When the diver wears the diving computer on his wrist, the bottom side 101 of the housing 10 fits against the wrist, and the diver can conveniently operate the diving computer through the button assembly 40.

[0040] It is worth mentioning that the number of button components 40 in the diving computer of this utility model is not limited, and they can be selected as needed. For example, in the appendix Figures 1 to 8 In this specific example of the diving computer of the present invention shown, each side 103 of the housing 10 is provided with two mounting cavities 12 and two housing perforations 13, and correspondingly, the number of switches 30 and the number of button assemblies 40 are both four.

[0041] Further, the housing 10 includes a bottom shell 14 and a top cover 15. The bottom shell 14 has a bottom shell cavity 140. The top cover 15 is installed on the bottom shell 14 to form the watertight cavity 11 of the housing 10 between the bottom shell 14 and the top cover 15. The assembly cavity 12 and the housing through hole 13 of the housing 10 are respectively formed in the bottom shell 14, that is, the housing through hole 13 of the housing 10 connects the assembly cavity 12 and the bottom shell cavity 140 of the bottom shell 14. Thus, the button assembly 40 is operably installed on the bottom shell 14. The circuit board 20 can be screwed onto the bottom shell 14 by screws. The switch 30 is attached to the circuit board 20. Thus, the switch 30 is connected to the circuit board 20. The circuit board 20 and the switch 30 are respectively disposed in the watertight cavity 11 of the housing 10. Optionally, in other examples of the diving computer of this utility model, the switch 30 is not mounted on the circuit board 20, but is locked to the bottom case 14, and the switch 30 and the circuit board 20 can be connected by a ribbon cable.

[0042] It is worth mentioning that the specific manner in which the top cover 15 is installed on the bottom shell 14 is not limited in the diving computer of this utility model. For example, in the attached... Figures 1 to 8 In this specific example of the diving computer of the present invention shown, a set of screws can be used to lock the top cover 15 to the bottom case 14.

[0043] The bottom surface of the bottom shell 14 has a concave bottom surface 141. The shape of the bottom surface 141 matches the shape of the diver's wrist. After the diver wears the diving computer watch on his wrist, the bottom surface 141 of the bottom shell 14 can fit better against the wrist to improve comfort.

[0044] The bottom case 14 has a strap hole 142 on each of the opposite sides of the bottom surface 141. The diving computer watch includes a wearing strap 50. One end of the wearing strap 50 passes through the two strap holes 142 of the bottom case 14 in sequence to set the wearing strap 50 to the housing 10. One end of the wearing strap 50 is provided with a hook-and-loop fastener 51 and the other end is provided with a loop fastener 52. The hook-and-loop fastener 51 can hook the loop fastener 52 so that the diving computer watch can be worn on the wrist by the wearing strap 50.

[0045] Furthermore, the top cover 15 has a viewing window 151, and the diving computer includes a display component 60, which includes a screen bracket 61, a display screen 62, and a tempered glass 63. The screen bracket 61 is mounted on the bottom shell 14. For example, a set of screws can be used to mount the screen bracket 61 to the bottom shell 14. The display screen 62 is mounted on the screen bracket 61 and connected to the circuit board 20. The periphery of the tempered glass 63 is stacked on the bottom shell 14, and the top cover 15 presses down on the edge of the tempered glass 63, so that the position of the display screen 62 corresponds to the position of the viewing window 151 of the top cover 15, thus allowing the content displayed on the display screen 62 to be viewed.

[0046] Preferably, the display assembly 60 includes a buffer frame 64, one side of which is attached to the edge of the screen bracket 61 and the display screen 62, and the other side is attached to the tempered glass 63. The buffer frame 64 is used to protect the display screen 62. (See attached...) Figures 1 to 8 In this specific example of the dive computer shown, the buffer frame 64 is made of black foam. To prevent deformation or misalignment of the buffer frame 64, one side of the buffer frame 64 and the screen bracket 61 can be glued together.

[0047] Furthermore, the diving computer includes an annular waterproof strip 70, which is sandwiched between the tempered glass 63 and the bottom case 14 to prevent water from entering the watertight cavity 11 of the housing 10 through the overlapping position of the bottom case 14 and the tempered glass 63.

[0048] Preferably, the bottom shell 14 has a groove 143, the depth of which is smaller than the diameter of the waterproof strip 70. After the waterproof strip 70 sinks into the groove 143 of the bottom shell 14, it protrudes from the bottom shell 14. After the tempered glass 63 is stacked on the bottom shell 14 and the top cover 15 presses down on the edge of the tempered glass 63 and the screws lock the top cover 15 onto the bottom shell 14, the tempered glass 63 and the bottom shell 14 cooperate to deform the waterproof strip 70, so that the waterproof strip 70 provides good sealing performance to prevent water from entering the watertight cavity 11 of the housing 10 through the stacked position of the bottom shell 14 and the tempered glass 63. It is understood that by sinking the waterproof strip 70 into the groove 143 of the bottom shell 14, after the top cover 15 is locked onto the bottom shell 14, it is beneficial to ensure that the waterproof strip 70 is reliably held between the bottom shell 14 and the tempered glass 63.

[0049] Reference Appendix Figure 5 and Figure 6 In this specific example of the diving computer of this utility model, the keycap 431 and the key lever 432 are integrally formed, which can be integrally injection molded from plastic material, so that the outer end of the key lever 432 can be set on the keycap 431. Optionally, in other specific examples of the diving computer of this utility model, the outer end of the key lever 432 can be installed on the keycap 431, so that the outer end of the key lever 432 is set on the keycap 431.

[0050] Continue to refer to the appendix Figure 5 and Figure 6 The housing 10 has at least one receiving cavity 16, which communicates with the assembly cavity 12. The elastic element 45 is received within the receiving cavity 16 of the housing 10. The keycap 431 conceals the receiving cavity 16 of the housing 10, thus making the elastic element 45 visually invisible and protecting it. Preferably, the receiving cavity 16 of the housing 10 is formed in the bottom shell 14.

[0051] Continue to refer to the appendix Figure 5 and Figure 6The button assembly 40 further includes an outer retaining spring 46, which holds the housing 10 in the receiving cavity 16 of the housing 10 and is attached to the blocking plate 42, such that the blocking plate 42 is configured to block the opening of the assembly cavity 12 of the housing 10, preventing the sealing ring 41 from falling off from the assembly cavity 12 of the housing 10, thereby reliably retaining the sealing ring 41 in the assembly cavity 12 of the housing 10.

[0052] Preferably, the housing 10 has at least one annular groove 17, which is disposed on the inner wall of the housing 10 defining the receiving cavity 16, and the groove 17 is adjacent to the opening of the assembly cavity 12. The outer side of the outer retaining spring 46 is engaged in the groove 17 of the housing 10, such that the outer retaining spring 46 enables the blocking piece 42 to be reliably disposed at the opening of the assembly cavity 12 of the housing 10. Preferably, the groove 17 of the housing 10 is formed in the bottom shell 14.

[0053] Continue to refer to the appendix Figure 7 and Figure 8 The housing 10 has a cable through hole 18 that communicates with the watertight cavity 11.
