[0002] When diving, divers wear a dive computer on their wrist to control and monitor the operational status of equipment such as cylinder valves and communication devices, as well as to view relevant information such as current depth. A dive computer typically includes a housing, a main circuit board, multiple switches, and multiple buttons. The main circuit board and the switches are screwed into the housing and located within its cavity. The circuit boards of each switch are connected to the main circuit board via ribbon cables or jumper wires. Each button is operably mounted on the housing, and the position of each button corresponds one-to-one with the position of each switch. When a diver presses a button, the corresponding switch is triggered, changing the operating state of the dive computer. A drawback of existing dive computers is that the assembly process requires screwing the main circuit board and each switch into the housing, with the circuit boards of each switch connected to the main circuit board via ribbon cables or jumper wires. This assembly method results in low assembly efficiency and high production costs. Therefore, improving the assembly efficiency and reducing production costs of dive computers is the technical problem that the inventors of this invention are committed to addressing.

The term "a" should not be construed as a limitation on the quantity.

[0035] Refer to the accompanying drawings of the specification of this utility model application. Figures 1 to 21 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 assembly 20 and a plurality of button assemblies 30.

[0036] The housing 10 has a housing cavity 101, and the circuit board assembly 20 is mounted in the housing cavity 101 of the housing 10. The housing 10 provides a watertight environment to keep the circuit board assembly 20 in a watertight environment. The circuit board assembly 20 includes a circuit board 21 and a plurality of switches 22 mounted on the circuit board 21. Each of the button assemblies 30 is pressably mounted on the housing 10, and the position of each button assembly 30 corresponds one-to-one with the position of each switch 22. When a button assembly 30 is pressed, the button assembly 30 applies pressure to the switch 22 to operate the switch 22 and change the operating state of the dive computer.

[0037] In the diving computer of this utility model, by mounting the switch 22 on the circuit board 21, it is not only beneficial to improve the assembly efficiency and reduce the production cost of the diving computer, but also beneficial to align the switch 22 and the button assembly 30, so that when the button assembly 30 is pressed, the button assembly 30 applies pressure to the switch 22 to operate the switch 22 and change the working state of the diving computer.

[0038] Specifically, the outer casing 10 includes a bottom shell 11 and a top cover 12. The bottom shell 11 has a bottom shell cavity 111, and the top cover 12 is installed on the bottom shell 11. The bottom shell cavity 111 of the bottom shell 11 forms the outer casing cavity 101 of the outer casing 10 between the bottom shell 11 and the top cover 12. The circuit board 21 can be locked into the bottom shell cavity 111 of the bottom shell 11 by screws 100, so that the circuit board 21 is reliably disposed in the outer casing cavity 101 of the outer casing 10.

[0039] It is worth mentioning that the specific manner in which the top cover 12 is installed on the bottom shell 11 is not limited in the diving computer of this utility model, as long as the top cover 12 can be reliably installed on the bottom shell 11. For example, in the appendix Figures 1 to 21 In this specific example of the diving computer of the present invention, the top cover 12 has a plurality of top cover through holes 121, and the bottom case 11 has a plurality of first bottom case threaded holes 112. The positions of each of the top cover through holes 121 of the top cover 12 and the positions of each of the first bottom case threaded holes 112 of the bottom case 11 correspond respectively. One end of each screw 100 extends from the top cover through hole 121 of the top cover 12 to each of the first bottom case threaded holes 112 of the bottom case 11, and this end of each screw 100 is screwed into the bottom case 11. Thus, a set of screws 100 is used to reliably install the top cover 12 into the bottom case 11.

[0040] The bottom case 11 has a concave bottom surface 113 and a pair of bottom case perforations 114, which are located on opposite sides of the bottom surface 113. The shape of the bottom surface 113 matches the shape of the diver's wrist. The dive computer includes a wearing strap 200, one end of which passes through the pair of bottom case perforations 114 of the bottom case 11 in sequence. Thus, the wearing strap 200 is disposed on the outer casing 10, wherein the wearing strap 200 is used to wear the dive computer on the diver's wrist.

[0041] Reference Appendix Figure 1 , Figures 4 to 6 and Figure 8The diving computer includes a display component 40, which further includes a bracket 41, a display screen 42, and a transparent protective cover 43. The display screen 42 is mounted on the bracket 41, for example, adhesive can be used to attach the display screen 42 to the bracket 41. The bracket 41 is mounted on the bottom shell 11, and the bracket 41 and the display screen 42 are recessed into the bottom shell cavity 111 of the bottom shell 11. The display screen 42 is connected to the circuit board 21. The periphery of the protective cover 43 is stacked on the edge of the opening of the bottom shell cavity 111 of the bottom shell 11, so that the opening of the bottom shell cavity 111 of the bottom shell 11 is closed by the protective cover 43. Thus, the display screen 42 is covered by the protective cover 43 to protect the display screen 42, and the content displayed on the display screen 42 can be seen through the protective cover 43. The top cover 12 has a viewing window 122 that extends through opposite sides of the top cover 12, wherein the top cover 12 presses down on the protective cover 43 to prevent the protective cover 43 from moving relative to the bottom shell 11, thereby ensuring that the periphery of the protective cover 43 is reliably stacked on the edge of the cavity 111 of the bottom shell 11.

[0042] It is worth mentioning that the specific manner in which the bracket 41 is installed on the bottom shell 11 is not limited in the diving computer of this utility model, as long as the bracket 41 can be reliably installed on the bottom shell 11. For example, in the attached... Figures 1 to 21 In this specific example of the diving computer of the present invention, the bracket 41 has a plurality of bracket through holes 411, and the bottom case 11 has a plurality of second bottom case threaded holes 115. The positions of each bracket through hole 411 of the bracket 41 and the positions of each second bottom case threaded hole 115 of the bottom case 11 are respectively corresponding. One end of each screw 100 extends from the bracket through hole 411 of the bracket 41 to the second bottom case threaded hole 115 of the bottom case 11, and the end of the screw 100 is screwed into the bottom case 11. Thus, the screw 100 is used to reliably install the bracket 41 into the bottom case 11.

[0043] The protective cover 43 may be, but is not limited to, tempered glass, so that the protective cover 43 can both allow the content displayed on the display screen 42 to pass through and protect the display screen 42.

[0044] To ensure that the top cover 12 can press down on the edge of the protective cover 43 and that the top cover 12 can be reliably installed on the bottom shell 11, the top cover 12 further has a top cover groove 123, which is connected to the viewing window 122. The depth dimension of the top cover groove 123 of the top cover 12 is the same as the thickness dimension of the edge of the protective cover 43, and the edge of the protective cover 43 is received in the top cover groove 123 of the top cover 12.

[0045] Furthermore, the display assembly 40 includes a flexible isolation pad 44. The outer side of the isolation pad 44 extends above the bracket 41, so that the outer side of the isolation pad 44 is clamped between the bracket 41 and the protective cover 43. The inner side of the isolation pad 44 extends above the edge of the display screen 42, so that the inner side of the isolation pad 44 is clamped between the display screen 42 and the protective cover 43. In this way, the isolation pad 44 can protect the display screen 42. Preferably, the material of the isolation pad 44 can be foam, which can be black. In addition, adhesive can be used to bond the isolation pad 44 and the bracket 41. In this way, the diving computer can prevent the isolation pad 44 from deforming and misaligning during assembly and use.

[0046] Preferably, the diving computer includes a waterproof strip 50, which is annular and is held between the bottom shell 11 and the protective cover 43 to prevent water from entering the outer shell cavity 101 of the outer shell 10 through the overlapping position of the bottom shell 11 and the protective cover 43. To ensure that the waterproof rubber strip 50 is reliably held between the bottom shell 11 and the protective cover 43, the bottom shell 11 is provided with an annular bottom shell groove 116. The depth of the bottom shell groove 116 is smaller than the diameter of the waterproof rubber strip 50. During the assembly of the diving computer watch, a portion of the waterproof rubber strip 50 is installed in the bottom shell groove 116 of the bottom shell 11, and another portion protrudes from the bottom shell 11. During the installation of the top cover 12 and the pressure applied by the top cover 12 to the protective cover 43, the protective cover 43 and the bottom shell 11 apply pressure to the waterproof rubber strip 50, causing the waterproof rubber strip 50 to undergo slight deformation. In this way, the waterproof rubber strip 50 can prevent water from entering the outer shell cavity 101 of the outer shell 10 through the overlapping position of the bottom shell 11 and the protective cover 43.

[0047] Reference Appendix Figures 1 to 6 , Figure 8The housing 10 has a housing through-hole 102, which communicates with the housing cavity 101. The diving computer includes a watertight cable assembly 60, which includes a watertight cable 61 and a nut 62. The watertight cable 61 further includes a first plug 611, a second plug 612, and a cable body 613 extending between the first plug 611 and the second plug 612. After the first plug 611 extends through the housing through-hole 102 of the housing 10 to the housing cavity 101 of the housing 10, the nut 62 is screwed into the first plug 611 in the housing cavity 101 of the housing 10 to install the first plug 611 of the watertight cable 61 onto the housing 10. The first plug 611 of the watertight cable 61 is connected to the circuit board 21.

[0048] In the appendix Figures 1 to 21 In this specific example of the diving computer of the present invention shown, the housing perforation 102 of the housing 10 is formed at one end of the bottom case 11, that is, the nut 62 installs the first plug 611 of the watertight cable 61 at one end of the bottom case 11.

[0049] Preferably, the middle part of the cable body 613 of the watertight cable 61 extends in a spiral shape, which makes the length of the watertight cable 61 extendable.

[0050] Reference Appendix Figure 8 and Figure 9 The circuit board 21 has multiple pairs of first plate through holes 211 and multiple pairs of second plate through holes 212. The positions of a pair of first plate through holes 211 and a pair of second plate through holes 212 are adjacent. Each switch 22 has a pair of first extension arms 221 and a pair of second extension arms 222. After the pair of first extension arms 221 of the switch 22 passes through the pair of first plate through holes 211 of the circuit board 21 and the pair of second extension arms 222 of the switch 22 passes through the pair of second plate through holes 212 of the circuit board 21, the pair of first extension arms 221 and the pair of second extension arms 222 of the switch 22 are respectively soldered to the circuit board 21. In this way, the switch 22 can be reliably mounted on the circuit board 21.

[0051] In the diving computer of this utility model, since the switch 22 is provided with a pair of first extension arms 221 and a pair of second extension arms 222, and the pair of first extension arms 221 and the pair of second extension arms 222 of the switch 22 are soldered to the circuit board 21 after passing through a pair of first plate through holes 211 and a pair of second plate through holes 212 respectively, it is convenient to position the switch 22 during the mounting process on the circuit board 21. After the switch 22 is mounted on the circuit board 21, when the switch 22 is subjected to lateral force, the switch 22 will not tilt, thereby ensuring the reliability and stability of the diving computer.

[0052] In the appendix Figures 1 to 21 In this specific example of the diving computer of the present invention, the circuit board 21 has four pairs of first plate through holes 211 and four pairs of second plate through holes 212. Each of the four corners of the circuit board 21 is provided with a pair of first plate through holes 211 and a pair of second plate through holes 212. Correspondingly, there are four switches 22, so that one switch 22 can be mounted at each of the four corners of the circuit board 21.

[0053] Preferably, each of the pair of first extension arms 221 of the switch 22 has a boss 2211 in its middle portion. During the mounting process of the switch 22, after the pair of first extension arms 221 of the switch 22 passes through the pair of first plate perforations 211 of the circuit board 21, the bosses 2211 of the pair of first extension arms 221 of the switch 22 hook onto the edges of the pair of first plate perforations 211 of the circuit board 21, preventing the switch 22 from falling off the circuit board 21, thereby facilitating the mounting of the switch 22 onto the circuit board 21. That is, during the mounting process of the switch 22 onto the circuit board 21, the bosses 2211 in the middle portion of the pair of first extension arms 221 of the switch 22 can serve as a pre-installation of the switch 22 onto the circuit board 21. In a specific example of the diving computer watch of this utility model, the bosses 2211 in the middle portion of the pair of first extension arms 221 of the switch 22 can be formed by bending the middle portion of the first extension arms 221.

[0054] Reference Appendix Figures 6 to 8The housing 10 has multiple assembly cavities 103 and multiple button through holes 104, the button through holes 104 communicating with the assembly cavities 103 and the housing cavity 101. The button assembly 30 includes at least one sealing ring 31, a blocking element 32, a button 33, a spring 34, and a retaining ring 35. The sealing ring 31 is installed in the assembly cavity 103 of the housing 10. The blocking element 32 has an element through hole 321 and is disposed in the housing 10, blocking the opening of the assembly cavity 103 to prevent the sealing ring 31 from detaching from the assembly cavity 103 of the housing 10. The button 33 includes a button cap 331 and a push rod 332 integrally extending outward from the button cap 331. The spring... Spring 34 is fitted onto push rod 332. The inner end of push rod 332 extends into the outer shell cavity 101 of outer shell 10 after passing sequentially through the element through hole 321 of blocking element 32, sealing ring 31, and button through hole 104 of outer shell 10. The opposite ends of spring 34 abut against button cap 331 and blocking element 32, respectively. Snap ring 35 is engaged with the inner end of push rod 332 to prevent the inner end of push rod 332 from exiting the button through hole 104 of outer shell 10. Thus, button assembly 30 is pressably mounted on outer shell 10. The inner end of push rod 332 is positioned opposite to switch 22.

[0055] When the diver presses the button cap 331, the button cap 331 and the push rod 332 move relative to the outer casing 10. During this process, on the one hand, the push rod 332 applies pressure to the switch 22 to operate the switch 22 and change the working state of the dive computer; on the other hand, the spring 34 is compressed and deformed to accumulate elastic potential energy. When the diver releases the pressure on the button cap 331, the spring 34 pushes the button cap 331 and the push rod 332 outward during the process of returning to the initial state, so that the button assembly 30 is reset. In the dive computer of this utility model, the mounting relationship between the switch 22 and the circuit board 21 can ensure that the switch 22 is not tilted after the push rod 332 applies pressure to the switch 22, thereby ensuring the reliability and stability of the dive computer.

[0056] Since the spring 34 is fitted onto the push rod 332, when the diver presses the button cap 331, causing the button cap 331 and the push rod 332 to move relative to the housing 10, the opposite ends of the spring 34 can always abut against the button cap 331 and the blocking element 32, preventing the spring 34 from tilting. Simultaneously, the spring 34 can apply pressure to the blocking element 32, preventing the blocking element 32 from moving relative to the housing 10. Thus, the blocking element 32 can prevent the sealing ring 31 from disengaging from the assembly cavity 103 of the housing 10, ensuring the watertightness of the diving computer. Preferably, there are two sealing rings 31.

[0057] In the appendix Figures 1 to 21 In this specific example of the diving computer of the present invention shown, the mounting cavity 103 and the button perforation 104 of the housing 10 are respectively formed on the side of the bottom case 11, so that the button assembly 30 is pressably mounted on the bottom case 11.

[0058] In the appendix Figures 1 to 21 In this specific example of the diving computer of the present invention, the outer casing 10 has four mounting cavities 103 and four button through holes 104. One mounting cavity 103 and one button through hole 104 are respectively provided at opposite ends on one side of the bottom casing 11, and one mounting cavity 103 and one button through hole 104 are respectively provided at opposite ends on the other side of the bottom casing 11. Correspondingly, there are four button assemblies 30, so that the positions of the four button assemblies 30 and the positions of the four switches 22 can correspond one-to-one.

[0059] Furthermore, the housing 10 has multiple receiving slots 105, which communicate with the assembly cavity 103. The spring 34 is received in the receiving slot 105 of the housing 10, and the button cap 331 covers the receiving slot 105 of the housing 10. In this way, the spring 34 can be hidden, and during the use of the diving computer, the diving computer can prevent foreign objects from jamming the spring 34, thereby ensuring the reliability and stability of the diving computer. It is understood that the receiving slots 105 of the housing 10 are formed in the bottom shell 11.

[0060] Further, the housing 10 has a plurality of protrusions 106 for forming the assembly cavity 103, and the protrusions 106 protrude toward the receiving groove 105 of the housing 10. The blocking element 32 includes a blocking plate 322, a blocking peripheral wall 323, and a blocking ring arm 324, and the blocking element 32 has an element groove 325. The element through hole 321 is formed in the blocking plate 322. The blocking peripheral wall 323 extends from the periphery of the blocking plate 322 in a direction perpendicular to the blocking plate 322 to form the element groove 325 between the blocking peripheral wall 323 and the blocking plate 322. The blocking ring arm 324 extends from the blocking peripheral wall 323 in a direction perpendicular to the blocking peripheral wall 323. The blocking element 32 is fitted onto the protrusion 106 of the housing 10 such that the protrusion 106 of the housing 10 protrudes into the element groove 325. That is, the blocking element 32 is fitted onto the protrusion 106 of the housing 10, the blocking ring arm 324 fits against the bottom of the receiving groove 105 of the housing 10, and one end of the spring 34 abuts against the blocking ring arm 324 of the blocking element 32. In this way, the blocking element 32 is disposed on the housing 10 so that the blocking element 32 reliably blocks the opening of the assembly cavity 103 and prevents the sealing ring 31 from detaching from the assembly cavity 103 of the housing 10.

[0061] Preferably, the housing 10 has at least one insertion slot 107 communicating with the receiving slot 105. The blocking element 32 includes at least one insertion piece 326 extending integrally outward from the blocking ring arm 324. When the blocking element 32 is installed on the housing 10, the inner wall of the housing 10 defining the receiving slot 105 presses against the insertion piece 326 of the blocking element 32, causing slight deformation of the insertion piece 326. After the insertion piece 326 of the blocking element 32 moves to a position corresponding to the insertion slot 107 of the housing 10, the insertion piece 326 returns to its initial state and engages with the insertion slot 107 of the housing 10, thus reliably positioning the blocking element 32 on the housing 10. To ensure good elasticity of the insertion piece 326 of the blocking element 32, additional... Figures 1 to 21 In this specific example of the dive computer of the present invention shown, the blocking element 32 may be made of metal or alloy, such as stainless steel.

[0062] The number of the inserts 326 of the blocking element 32 is not limited in the diving computer of this invention. For example, in the attached... Figures 1 to 21In this specific example of the dive computer of the present invention shown, the number of the inserts 326 of the blocking element 32 is multiple, and these inserts 326 are arranged in a ring.

[0063] Appendix Figures 10 to 21 The assembly process of the diving computer shown is as follows.

[0064] Reference Appendix Figure 10 and Figure 11 Two sealing rings 31 are sequentially installed into the assembly cavity 103 of the housing 10, wherein the outer diameter of the sealing ring 31 is slightly larger than the inner diameter of the assembly cavity 103 of the housing 10, so that after the sealing ring 31 is installed into the assembly cavity 103 of the housing 10, the sealing ring 31 is deformed by the housing 10. To facilitate the installation of the sealing ring 31 into the assembly cavity 103 of the housing 10, the opening of the assembly cavity 103 of the housing 10 is provided with a chamfer.

[0065] Reference Appendix Figure 12 The blocking element 32 is installed on the housing 10 by fitting the blocking element 32 onto the protrusion 106 of the housing 10. The blocking element 32 blocks the opening of the assembly cavity 103 of the housing 10, thereby preventing the sealing ring 31 from falling out of the assembly cavity 103 of the housing 10.

[0066] Reference Appendix Figures 13 to 15 After the spring 34 is fitted onto the push rod 332, the inner end of the push rod 332 is allowed to pass sequentially through the element through hole 321 of the blocking element 32, the sealing ring 31, and the button through hole 104 of the housing 10. Then, the retaining ring 35 is snapped onto the inner end of the push rod 332, wherein the spring 34 is located in the receiving groove 105 of the housing 10, and the opposite ends of the spring 34 abut against the button cap 331 and the blocking element 32, respectively. Thus, the button assembly 30 is pressably mounted on the housing 10. Other button assemblies 30 can be mounted on the housing 10 in the same manner. To facilitate the inner end of the push rod 332 passing through the sealing ring 31, the inner end of the push rod 332 is chamfered.

[0067] Reference Appendix Figure 16After each switch 22 is attached to the circuit board 21 to form the circuit board assembly 20, the circuit board 21 is locked to the bottom shell 11 by a set of screws 100. At this time, on the one hand, the circuit board assembly 20 is located in the bottom shell cavity 111 of the bottom shell 11, and on the other hand, the inner end of the push rod 332 of the button 33 of each button assembly 30 corresponds one-to-one with the position of each switch 22.

[0068] Reference Appendix Figure 17 After the first plug 611 of the watertight cable 61 extends through the housing through hole 102 of the housing 10 to the housing cavity 101 of the housing 10, the nut 62 is screwed into the housing cavity 101 of the housing 10 to install the watertight cable assembly 60 on the housing 10, and then the first plug 611 and the circuit board 21 are connected.

[0069] Reference Appendix Figure 18 After the display screen 42 is attached to the bracket 41, the bracket 41 is locked to the bottom shell 11 by a set of screws 100. At this time, the bracket 41 and the display screen 42 are located in the bottom shell cavity 111 of the bottom shell 11.

[0070] Reference Appendix Figure 19 The isolation pad 44 is attached to the edge of the bracket 41 and the display screen 42, and the waterproof strip 50 is installed in the bottom shell groove 116 of the bottom shell 11.

[0071] Reference Appendix Figure 20 The periphery of the protective cover 43 is stacked on the edge of the cavity 111 of the bottom shell 11. At this time, the isolation pad 44 contacts the periphery of the protective cover 43, the waterproof strip 50 is clamped between the bottom shell 11 and the protective cover 43, and the protective cover 43 covers the display screen 42.

[0072] Reference Appendix Figure 21 The top cover 12 is installed on the bottom shell 11 by a set of screws 100, wherein the top cover 12 presses against the periphery of the protective cover 43 to prevent the protective cover 43 from moving relative to the bottom shell 11, and the middle part of the protective cover 43 corresponds to the viewing window 122 of the top cover 12. The diving computer is thus assembled.

[0073] Appendix Figure 22 A modified example of the dive computer of this invention is shown, with reference to the appendix. Figures 1 to 21 Unlike the dive computer shown, the attached... Figure 22In this specific example of the diving computer of the present invention shown, after the blocking element 32 is fitted onto the protrusion 106 of the housing 10, the blocking ring arm 324 of the blocking element 32 is locked to the housing 10 by the screw 100, so that the blocking element 32 is reliably disposed on the housing 10.
