Description

Technical Field

[0001] This utility model relates to the field of digital key technology, and more specifically, to a low-cost laser-welded dustproof and waterproof digital key. Background Technology

[0002] Traditional IP67 dustproof and waterproof digital key solutions mostly employ a rubber ring seal between the housing and the top cover, or use laser welding to connect them. However, the circuit board is secured using internal screws or individual solder pads. Using a rubber ring seal between the housing and the top cover has several drawbacks: complex manufacturing process and assembly structure; rubber is prone to aging, leading to a decline in waterproof performance over long-term use. Utility Model Content

[0003] Therefore, this utility model provides a low-cost laser-welded dustproof and waterproof digital key, which not only has a simpler structure but also a more stable laser welding method.

[0004] To address the aforementioned issues, this utility model provides a low-cost laser-welded dustproof and waterproof digital key, comprising: a housing assembly, wherein an integrally formed connector is provided within the housing assembly; a plate assembly, which is connected to the housing assembly, and the connector is also connected to the plate assembly; and a top cover assembly, which covers the housing assembly and positions the plate assembly between the housing assembly and the plate assembly; wherein the top cover assembly and the housing assembly are fixed together by laser welding.

[0005] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the connector and housing assembly to be integrally molded, the structural components are simplified, making assembly more convenient and faster. At the same time, by setting the plate assembly, housing assembly and connector to be connected together, the installation of the plate assembly is more convenient. The plate assembly is sandwiched in the middle by the top cover assembly and housing assembly, making the fixation of the plate assembly more convenient. Finally, the use of laser welding makes the overall dustproof and waterproof effect better, the overall structural reliability is stronger, and it is more corrosion resistant. Moreover, due to fewer parts and laser welding, the overall weight is lighter.

[0006] In one embodiment of this utility model, the upper cover assembly further includes: multiple limiting members, which are arranged in a row and abut against the plate assembly.

[0007] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting up multiple limiting components in an arrangement to abut against the plate assembly, the plate assembly can be better fixed when the upper cover assembly is placed on the plate assembly, ensuring that the plate assembly will not shift, and making the overall structure more stable.

[0008] In one embodiment of this utility model, the housing assembly further includes: multiple support members, which abut against the plate assembly, and the multiple support members and multiple limiting members cooperate to restrict the position of the plate assembly.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting multiple support components to cooperate with multiple limiting components, the position of the plate assembly is restricted, ensuring that the plate assembly will not shift vertically after installation, thus making the plate assembly more stable and the overall structure more stable. At the same time, no additional screws or bolts are needed for fixing, making the structure simpler.

[0010] In one embodiment of this utility model, the low-cost laser-welded dustproof and waterproof digital key further includes: a plate assembly having a first limiting hole and a second limiting hole; and a housing assembly having a first mating part and a second mating part, wherein the first mating part and the first limiting hole are correspondingly mated, and the second mating part and the limiting hole are correspondingly mated.

[0011] Compared with the existing technology, the technical effects achieved by adopting this technical solution are as follows: by setting the first limiting hole and the second limiting hole to cooperate with the first mating part and the second mating part set on the shell assembly, it is more convenient and faster to position and install the plate assembly, and at the same time, it makes the fixing of the plate assembly more stable, ensuring that the plate assembly will not shift after fixing, and making the overall structure more stable.

[0012] In one embodiment of this utility model, the second limiting hole is a waist hole and the first limiting hole is a round hole; and the first limiting hole and the second limiting hole are arranged diagonally.

[0013] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting two limiting holes diagonally, the plate assembly can be better limited after being fixed by the two limiting holes and two mating parts, ensuring that the plate assembly will not shift. At the same time, the setting of the waist hole makes the fixing of the plate assembly more convenient and quick.

[0014] In one embodiment of this utility model, the upper cover assembly is provided with multiple extensions, the extensions abutting against the plate assembly; the shell assembly is provided with multiple protrusions, the multiple protrusions and the multiple extensions abutting against each other to limit the position of the plate assembly.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by setting multiple extensions to abut against the plate assembly, the plate assembly is fixed more stably. At the same time, with the multiple protrusions set in the shell assembly, the limiting of the plate assembly is more convenient, thereby ensuring that the plate assembly will not move after being fixed, and improving the efficiency and convenience of fixing.

[0016] In one embodiment of this utility model, the housing assembly is provided with a limiting rib; the upper cover assembly is provided with a recessed portion, which is provided corresponding to the limiting rib, so that the limiting rib portion is located in the recessed portion.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting corresponding limiting ribs and recesses, the assembly of the top cover assembly and the housing assembly is more convenient and the positioning is faster. At the same time, by setting the recesses, the risk of glue overflow after laser welding can be avoided, thereby ensuring the stability and reliability of welding.

[0018] In one embodiment of this utility model, the relative position between the housing assembly and the top cover assembly before laser welding is defined as the first state, and the relative position between the housing assembly and the top cover assembly after laser welding is defined as the second state; the top cover assembly is provided with a limiting member; in the first state, the limiting rib and the bottom of the recessed portion abut together, and there is a gap between the limiting member and the plate assembly; in the second state, the limiting rib portion and the bottom of the recessed portion are fused together, and the limiting member and the plate assembly abut together.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: by setting a gap between the pre-laser welding limiting component and the plate assembly, the limiting rib and the bottom of the recess abut against each other, and after laser welding, the limiting rib and the bottom of the recess are fused together, while the limiting component and the plate assembly abut against each other. This allows the plate assembly to be fixed by the collapse caused by laser welding, eliminating the need for corresponding welding feet or screws, saving costs and reducing weight.

[0020] In one embodiment of this invention, the material of the top cover assembly is a material that allows the laser beam to penetrate.

[0021] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by setting the material of the upper cover component to be a material that can be penetrated by the laser beam, laser welding is made more convenient after the components are assembled.

[0022] By adopting the technical solution of this utility model, the following technical effects can be achieved:

[0023] (1) By setting the connector and housing assembly as an integral molding, the structural components are simpler and the assembly is more convenient and quick. At the same time, by setting the plate assembly, housing assembly and connector to be connected, the installation of the plate assembly is more convenient. The plate assembly is sandwiched in the middle by the top cover assembly and housing assembly, making the fixing of the plate assembly more convenient. Finally, laser welding is used, which makes the overall dustproof and waterproof effect better, the overall structure more reliable, and more corrosion resistant. Due to the fewer parts and the use of laser welding, the overall weight is lighter.

[0024] (2) By setting two limiting holes diagonally, the plate assembly can be better limited after being fixed by the two limiting holes and two mating parts, ensuring that the plate assembly will not shift. At the same time, the setting of the waist hole makes it easier and faster to fix the plate assembly.

[0041] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] [First Embodiment]

[0043] See Figures 1-12 This utility model provides a low-cost laser-welded dustproof and waterproof digital key 100, comprising: a housing assembly 110, wherein an integrally formed connector 120 is provided inside the housing assembly 110; a plate assembly 130, which is connected to the housing assembly 110, and the connector 120 is also connected to the plate assembly 130; and a top cover assembly 140, which covers the housing assembly 110 and such that the plate assembly 130 is located between the housing assembly 110 and the plate assembly 130; wherein the top cover assembly 140 and the housing assembly 110 are fixed by laser welding.

[0044] Specifically, during the injection molding of the housing assembly 110, the connector 120 and the housing assembly 110 are integrally molded through overmolding, eliminating the need for welding the connector 120 separately to the plate assembly 130. Simultaneously, during the injection molding of the top cover assembly 140, the gate location is avoided to prevent uneven welding. Furthermore, the top cover assembly 140 is made of plastic, which is a permeable layer, allowing the laser beam to penetrate and irradiate the plastic absorption layer of the housing, causing fusion. The entire perimeter of the top cover is laser-welded, enabling the product to achieve an IP67 dust and water resistance rating.

[0045] Furthermore, after the injection molding of each component is completed, the components are assembled. First, the first limiting hole 131 and the second limiting hole 132 on the plate assembly 130 are correspondingly embedded and engaged with the first mating part 112 and the second mating part 113 on the housing assembly 110. After installation and fixation, the multiple support members 111 at the bottom of the housing assembly 110 support the plate assembly 130, and then the connector 120 and the plate assembly 130 are subsequently welded.

[0046] Furthermore, after the plate assembly 130 and connector 120 are welded together, the top cover assembly 140 is installed onto the housing assembly 110, so that the protrusion 114 is engaged in the middle position of the extension 142, and the limiting protrusion 116 is engaged in the middle position of the limiting member 141, thereby forming a limiting fixation and positioning. After fixation, the overall structure is in the first state, that is, the limiting rib 115 provided on the outer side of the housing assembly 110 is located in the corresponding recess 143 provided on the top cover assembly 140, and at this time there is still a gap between the limiting member 141 and the plate assembly 130. Then, the top cover assembly 140 and the housing assembly 110 are laser welded. After welding, the overall structure is in the second state, that is, the limiting rib 115 is fused with the bottom of the recess 143, so that the limiting member 141 and the plate assembly 130 are abutted and fixed. Specifically, the collapse distance after fusion is 3mm, that is, the entire top cover moves 3mm towards the outer shell, and this distance is the gap in the first state.

[0047] Preferably, by making the connector 120 and the housing assembly 110 integrally molded, the structural components are simplified, making assembly more convenient and quick. At the same time, by making the plate assembly 130, the housing assembly 110, and the connector 120 cooperate to connect, the installation of the plate assembly 130 is more convenient. The plate assembly 130 is sandwiched in the middle by the top cover assembly 140 and the housing assembly 110, making it easier to fix the plate assembly 130. Finally, the use of laser welding makes the overall dustproof and waterproof effect better, the overall structural reliability stronger, and more corrosion resistant. Moreover, due to the fewer parts and the use of laser welding, the overall weight is lighter.

[0048] Specifically, the top cover assembly 140 also includes a plurality of limiting members 141, which are arranged in a row and abut against the plate assembly 130.

[0049] Preferably, by arranging multiple limiting members 141 to abut against the plate assembly 130, the plate assembly 130 can be better fixed when the upper cover assembly 140 is placed on the plate assembly 130, ensuring that the plate assembly 130 will not shift, and making the overall structure more stable.

[0050] Specifically, the housing assembly 110 also includes: a plurality of support members 111, which abut against the plate assembly 130, and the plurality of support members 111 and the plurality of limiting members 141 cooperate to limit the position of the plate assembly 130.

[0051] Preferably, by setting multiple support members 111 to cooperate with multiple limiting members 141, the position of the plate assembly 130 is restricted, ensuring that the plate assembly 130 will not shift vertically after installation, thereby making the fixing of the plate assembly 130 more stable, and thus making the overall structure more stable. At the same time, no additional screws or bolts are needed for fixing, making the structure simpler.

[0052] Specifically, the low-cost laser-welded dustproof and waterproof digital key 100 also includes: a plate assembly 130 having a first limiting hole 131 and a second limiting hole 132; and a housing assembly 110 having a first mating part 112 and a second mating part 113, wherein the first mating part 112 and the first limiting hole 131 are correspondingly mated, and the second mating part 113 and the limiting hole are correspondingly mated.

[0053] Preferably, by setting the first limiting hole 131 and the second limiting hole 132 to cooperate with the first mating part 112 and the second mating part 113 set on the housing assembly 110, the plate assembly 130 is more convenient and quick to position and install, and the plate assembly 130 is more stable to fix, ensuring that the plate assembly 130 will not shift after being fixed, and the overall structure is more stable.

[0054] Specifically, the second limiting hole 132 is a waist hole, and the first limiting hole 131 is a round hole; and the first limiting hole 131 and the second limiting hole 132 are set diagonally.

[0055] Preferably, by setting two limiting holes diagonally, the plate assembly 130 can be better positioned after being fixed by the two limiting holes and two mating parts, ensuring that the plate assembly 130 will not shift. At the same time, the setting of the waist hole makes it easier and faster to fix the plate assembly 130.

[0056] Specifically, the top cover assembly 140 is provided with multiple extensions 142, and the extensions 142 partially abut against the plate assembly 130; the shell assembly 110 is provided with multiple protrusions 114, and the multiple protrusions 114 and the multiple extensions 142 abut against each other to limit the plate assembly 130.

[0057] Preferably, by setting multiple extensions 142 to abut against the plate assembly 130, the plate assembly 130 is fixed more stably. At the same time, in conjunction with the multiple protrusions 114 set in the housing assembly 110, the limiting of the plate assembly 130 is made more convenient, thereby ensuring that the plate assembly 130 will not move after being fixed, thus improving the efficiency and convenience of fixing.

[0058] Specifically, the housing assembly 110 is provided with a limiting rib 115; the upper cover assembly 140 is provided with a recess 143, which is provided corresponding to the limiting rib 115, such that the limiting rib 115 is partially located in the recess 143.

[0059] Preferably, by setting the limiting rib 115 and the recessed part 143 accordingly, the upper cover assembly 140 and the shell assembly 110 are more convenient to assemble and the positioning is faster. At the same time, by setting the recessed part 143, the risk of glue overflow after laser welding can be avoided, thereby ensuring the stability and reliability of welding.

[0060] Specifically, the relative position between the housing assembly 110 and the upper cover assembly 140 before laser welding is defined as the first state, and the relative position between the housing assembly 110 and the upper cover assembly 140 after laser welding is defined as the second state; the upper cover assembly 140 is provided with a limiting member 141; in the first state, the limiting rib 115 and the bottom of the recess 143 abut together, and there is a gap between the limiting member 141 and the plate assembly 130; in the second state, the limiting rib 115 is partially fused with the bottom of the recess 143, and the limiting member 141 abuts against the plate assembly 130.

[0061] Preferably, by setting a gap between the pre-laser welding limiting member 141 and the plate assembly 130, the limiting rib 115 and the bottom of the recessed portion 143 abut against each other, and after laser welding, the limiting rib 115 and the bottom of the recessed portion 143 are fused together, while the limiting member 141 and the plate assembly 130 abut against each other, so that the plate assembly 130 is fixed by the collapse of the laser welding, so that there is no need for corresponding welding feet or screws for fixation, saving costs and reducing weight.

[0062] Specifically, the material of the top cover assembly 140 is a material that allows the laser beam to penetrate.

[0063] Preferably, by setting the material of the cover assembly 140 to be a material that allows the laser beam to penetrate, laser welding becomes more convenient after the components are assembled.
