Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted terminal technology, and in particular to a shell structure and a vehicle-mounted terminal. Background Technology

[0002] Traditional vehicle-mounted terminal casings generally suffer from insufficient waterproofing (typically only IP54 rating) and poor heat dissipation, especially at connector mounting areas. To address these issues, an existing vehicle-mounted electric vehicle charger provides a casing structure including a base and a top cover. The mainboard is mounted within a cavity formed by the base and top cover. The inner bottom surface of the base has a heat dissipation protrusion with slots around its perimeter. The upper surface of the protrusion is flat. A heat dissipation structure is located on the outer bottom surface of the base. The top cover has several connector ports corresponding to the shapes and positions of the connector interfaces on the mainboard, and also several injection holes. While this structure improves waterproofing through injection and utilizes the heat dissipation protrusion and structure for heat dissipation, it requires filling the entire cavity with adhesive. This significantly increases material costs and completely solidifies and encapsulates internal components, making them unrepairable in case of malfunction and affecting product lifespan. Utility Model Content

[0003] This utility model addresses the technical problems existing in the prior art by providing a shell structure and vehicle terminal for a vehicle-mounted terminal. It ensures the waterproof effect of the connector installation part, avoids the curing and encapsulation problems caused by overall potting, and reduces the amount of glue used, thereby reducing costs.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a shell structure for a vehicle terminal, including a shell body, wherein the shell body has an inner cavity for mounting a PCB module of the vehicle terminal, and the shell body also has a glue injection baffle wall, which divides the inner cavity into an installation cavity and a glue injection cavity, and the glue injection baffle wall has a clearance hole connecting the installation cavity and the glue injection cavity, the clearance hole allowing the PCB module to pass through and sealingly engage with the PCB module; the shell body has at least one through hole connecting the glue injection cavity, the at least one through hole for the connector of the PCB module to pass through and sealingly engage with the connector; the shell body also has a glue injection hole and at least one vent hole connecting the glue injection cavity.

[0005] Furthermore, the shell body includes an upper shell and a lower shell, which are sealed together and enclose the inner cavity. The glue injection baffle includes a first baffle disposed in the upper shell and a second baffle disposed in the lower shell. The first baffle and the second baffle are correspondingly disposed and the clearance hole is formed between them.

[0006] Furthermore, the upper and lower housings are connected by screws, and a first waterproof rubber ring fits between them.

[0007] Furthermore, it also includes a battery cover assembly, wherein the top of the housing body is provided with a first opening communicating with the mounting cavity, the battery cover assembly is installed at the first opening, and a second waterproof rubber ring is fitted between the battery cover assembly and the housing body.

[0008] Furthermore, the battery cover assembly includes a battery cover and a light guide post, the battery cover and the light guide post being integrally formed, and the light guide post corresponding to the indicator light of the PCB module.

[0009] Furthermore, it also includes a seal that fits between the clearance hole and the PCB module.

[0010] Furthermore, the top of the shell body is provided with a second opening that communicates with the mounting cavity, and a waterproof and breathable valve is installed at the second opening.

[0011] Furthermore, the bottom of the housing body is provided with a heat dissipation protrusion, which extends upward into the mounting cavity and contacts the heat-generating element of the PCB module.

[0012] Furthermore, the volume of the glue injection cavity is smaller than the volume of the mounting cavity.

[0013] This utility model also provides a vehicle-mounted terminal, including a PCB module. One end of the PCB module is provided with at least one connector. It also includes the housing structure of the vehicle-mounted terminal of this utility model. The PCB module is installed in the inner cavity and is sealed with the clearance hole. The main body of the PCB module is located in the mounting cavity. The end of the PCB module with the connector is located in the glue injection cavity. The connector passes through the through hole and is sealed with the through hole. Waterproof glue is injected into the glue injection cavity.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The shell body of this utility model also includes a glue-injection baffle wall, which divides the inner cavity into an installation cavity and a glue-injection cavity. The glue-injection baffle wall has a clearance hole connecting the installation cavity and the glue-injection cavity, allowing the PCB module to pass through and seal with it. The shell body has at least one through hole connecting to the glue-injection cavity, allowing the connector of the PCB module to pass through and seal with it. The shell body also has a glue-injection hole connecting to the glue-injection cavity and at least one vent hole. This structure of the utility model, by dividing the inner cavity into an installation cavity and a glue-injection cavity through the glue-injection baffle wall, allows only the glue-injection cavity to be glued after the PCB module is installed. This ensures the waterproof effect of the connector installation area and avoids the problem of complete curing and encapsulation of internal components caused by overall glue injection, making the PCB module still repairable. At the same time, setting up a glue-injection cavity for local glue injection reduces the amount of glue used and lowers costs. In addition, a vent hole is provided to facilitate the discharge of gas originally present in the glue-injection cavity.

[0017] 3. In this utility model, a second waterproof rubber ring is fitted between the battery cover assembly and the shell body, and the battery cover assembly includes a battery cover and a light guide post, which are integrally formed, thereby simplifying the assembly process and achieving a waterproof effect.

[0018] 4. The top of the shell body of this utility model is provided with a second opening that connects to the mounting cavity. A waterproof and breathable valve is installed at the second opening to balance the air pressure between the mounting cavity and the outside.

[0019] 5. The bottom of the shell body of this utility model is provided with a heat dissipation protrusion. The heat dissipation protrusion extends upward into the mounting cavity and contacts the heat-generating element of the PCB module, thereby enabling the device to meet the heat dissipation function requirements.

[0027] Please see Figures 1-3As shown, the present invention discloses a vehicle-mounted terminal housing structure, comprising a housing body 1. The housing body 1 has an inner cavity 11 for mounting a PCB module 2 of the vehicle-mounted terminal. The housing body 1 also has a glue-injection baffle 12, which divides the inner cavity 11 into a mounting cavity 111 and a glue-injection cavity 112. The glue-injection baffle 12 has a clearance hole 123 connecting the mounting cavity 111 and the glue-injection cavity 112, allowing the PCB module 2 to pass through and be sealed to it. The housing body 1 has at least one through hole 13 connecting to the glue-injection cavity 112, allowing a connector 21 of the PCB module 2 to pass through and be sealed to it. The housing body 1 also has a glue-injection hole 14 connecting to the glue-injection cavity 112 and at least one vent hole 15. Specifically, the number of through holes 13 corresponds to the number of connectors 21, and the through holes 13 are located on the side wall of the housing body 1. Both the glue injection hole 14 and the vent hole 15 are located on the side wall of the shell body 1, and the through hole 13, the glue injection hole 14 and the vent hole 15 are located on the same side of the shell body 1. There are five vent holes 15. The glue injection hole 14 is located in the middle of the side wall of the shell body 1 and below the through hole 13. There is one vent hole 15 on each side of the glue injection hole 14. There are three vent holes 15 above the through hole 13. However, the number and position of the glue injection hole 14 and the vent hole 15 are not limited to this and can be set according to the user's needs.

[0028] The shell body 1 includes an upper shell 16 and a lower shell 17, which are sealed together and form the inner cavity 11. The glue-filling baffle 12 includes a first baffle 121 disposed in the upper shell 16 and a second baffle 122 disposed in the lower shell 17. The first baffle 121 and the second baffle 122 are correspondingly disposed and form the clearance hole 123 between them. Specifically, the first baffle 121 has a notch at the bottom and the second baffle 122 has a notch at the top. When the upper shell 16 and the lower shell 17 are connected, the notch at the bottom of the first baffle 121 and the notch at the top of the second baffle 122 together form the clearance hole 123. Similarly, the side wall of the upper shell 16 has a notch at the bottom and the side wall of the lower shell 17 has a notch at the top. When the upper shell 16 and the lower shell 17 are connected, the notch at the bottom of the side wall of the upper shell 16 and the notch at the top of the side wall of the lower shell 17 together form the through hole 13.

[0029] The upper housing 16 and the lower housing 17 are connected by screws, and a first waterproof rubber ring 3 is fitted between them. Specifically, the bottom of the upper housing 16 is provided with a first groove 163, the first waterproof rubber ring 3 is installed in the first groove 163, and the lower housing 17 abuts against the first waterproof rubber ring 3.

[0030] This utility model also includes a battery cover assembly 4. The top of the shell body 1 is provided with a first opening 161 communicating with the mounting cavity 111. The battery cover assembly 4 is installed at the first opening 161, and a second waterproof rubber ring 5 is fitted between it and the shell body 1 to achieve a waterproof effect.

[0032] This utility model also includes a sealing element, which is fitted between the clearance hole 123 and the PCB module 2 to achieve a sealed fit between the clearance hole 123 and the PCB module 2. Specifically, the sealing element is a sealing foam 6, and there are two sealing foams 6. One sealing foam 6 is fitted between the PCB module 2 and the first retaining wall 121, and the other sealing foam 6 is fitted between the PCB module 2 and the second retaining wall 122, but it is not limited to this.

[0033] The top of the shell body 1 is provided with a second opening 162 that communicates with the mounting cavity 111. Specifically, the top of the upper shell 16 is provided with a second opening 162, and a waterproof and breathable valve 7 is installed at the second opening 162 to balance the air pressure between the mounting cavity 111 and the outside.

[0034] The bottom of the housing body 1 is provided with a heat dissipation protrusion 171. Specifically, the bottom of the lower housing 17 is provided with a heat dissipation protrusion 171. The heat dissipation protrusion 171 extends upward into the mounting cavity 111 and contacts the heat-generating element of the PCB module 2, thereby enabling the device to meet the heat dissipation requirements.

[0035] In this embodiment, the volume of the injection cavity 112 is smaller than the volume of the mounting cavity 111, but it is not limited thereto. The specific volume of the injection cavity 112 and the mounting cavity 111 is set according to the PCB module 2 selected by the user.

[0036] This utility model discloses a vehicle-mounted terminal housing structure. An adhesive injection barrier 12 divides the inner cavity 11 into an installation cavity 111 and an adhesive injection cavity 112. After installing the PCB module 2, adhesive is only injected into the adhesive injection cavity 112. This ensures the waterproof effect of the connector 21 installation area and avoids the problem of complete curing and encapsulation of internal components caused by overall adhesive injection, allowing the PCB module 2 to remain repairable. Simultaneously, by setting up the adhesive injection cavity 112 for localized adhesive injection, the amount of adhesive used is reduced, lowering costs. Furthermore, a vent 15 is provided to facilitate the discharge of any existing gas within the adhesive injection cavity 112.

[0037] Please see Figures 1-3 As shown, this utility model discloses a vehicle-mounted terminal, including a PCB module 2. One end of the PCB module 2 is provided with at least one connector 21. Specifically, the PCB module 2 also includes electronic components such as indicator lights and heating elements. The remaining electronic components, except for the connector 21, are disposed on the main body of the PCB module 2. The utility model also includes a housing structure for the vehicle-mounted terminal. The PCB module 2 is installed in the inner cavity 11 and sealed with the clearance hole 123. The main body of the PCB module 2 is located in the mounting cavity 111. The end of the PCB module 2 with the connector 21 is located in the injection cavity 112. The connector 21 protrudes from the through hole 13 and seals with the through hole 13. Specifically, the outer side of the connector 21 is provided with a sealing protrusion, which abuts against the outer or inner side of the through hole 13 to achieve a sealed fit between the connector 21 and the through hole 13. The injection cavity 112 is filled with waterproof adhesive to achieve a waterproof effect.

[0038] This utility model discloses a vehicle-mounted terminal. During installation, the PCB module 2 is first placed in the corresponding position on the lower housing 17, ensuring that the main body of the PCB module 2 is located in the mounting cavity 111. One end of the PCB module 2 with the connector 21 is located in the injection cavity 112, and the connector 21 passes through the through hole 13. Then, the upper housing 16 and the lower housing 17 are assembled into an IP68 waterproof unit by screwing together the first waterproof rubber ring 3. During this process, the sealing foam 6 achieves a sealing fit between the PCB module 2 and the clearance hole 123, and the sealing protrusion of the connector 21 achieves a sealing fit between the connector 21 and the through hole 13, preventing waterproof adhesive from leaking out of the clearance hole 123 and the through hole 13. Then, waterproof adhesive is injected through the injection hole 14, filling the injection cavity 112 and wrapping the pins of the connector 21. Air previously present in the injection cavity 112 is expelled through the vent hole 15, achieving the IP68 waterproof rating requirement for the connector 21. Installation is then complete. During use, the heat dissipation boss 171 set on the lower housing 17 can contact the heat-generating element of the PCB module 2 to dissipate heat, so that the equipment can meet the heat dissipation requirements. At the same time, the air pressure between the mounting cavity 111 and the outside can be balanced by the waterproof and breathable valve 7.
