Technical Field

[0001] The utility model relates to the technical field of industrial vehicle-mounted computers, in particular to a waterproof structure for industrial vehicle-mounted computers. Background Technique

[0002] Industrial vehicle-mounted computers are installed on heavy vehicles such as container trucks, warehousing forklifts, and mining trucks. Their working environment is very harsh, and there are usually specific waterproof test requirements. For example, the ISO 16750 standard classifies the waterproof level according to the vehicle type and installation location. In addition, the waterproof design of automotive cables is also very important because it connects various electrical components on the entire vehicle. Once the waterproofing of the cable fails, it may cause the electrical functions to fail or more serious consequences.

[0003] Currently, the wire outlet of industrial vehicle-mounted computers usually adopts a direct wire outlet and is connected through a waterproof connector. However, this requires that the devices connected to the industrial vehicle-mounted computer must also be of this type of connector. If the device is not of this type of connector, the connector needs to be replaced, which requires professional operation, is time-consuming and laborious, is not conducive to the adaptability of industrial vehicle-mounted computers, and also affects the aesthetics. Content of the Utility Model

[0004] The purpose of the utility model is to provide a waterproof structure for industrial vehicle-mounted computers, which does not require the replacement of connectors for connected devices while ensuring waterproofing, greatly enhancing the adaptability of the devices.

[0006] Further, installation card slots are arranged in both the first grooves and the second grooves; correspondingly, installation convex rings are arranged on the wire-passing waterproof rings; the installation convex rings are embedded in the installation card slots.

[0007] Further, the sealing part of the above-mentioned waterproof structure for industrial vehicle-mounted computers is made of tensile wire silica gel.

[0008] Furthermore, in the above-mentioned waterproof structure of the industrial vehicle-mounted computer, the sealing part further includes a fixing post and a positioning plug; the lower housing of the device is provided with a fixing groove corresponding to the fixing post and a positioning hole corresponding to the positioning plug; the fixing post is embedded in the fixing groove, and the positioning plug is inserted into the positioning hole.

[0009] Furthermore, at least one annular protrusion is provided on the sealing gasket in the above-mentioned waterproof structure of the industrial vehicle-mounted computer.

[0010] By passing the cable through the cable-passing waterproof ring and connecting the cable-passing waterproof ring with the sealing gasket to form a complete annular seal, a good sealing effect is achieved between the lower housing and the upper housing of the device. The temporarily unused cable-passing waterproof ring is blocked by a plug, which not only provides waterproofing but also makes the device more aesthetically pleasing. Description of the Drawings

Detailed Description of the Invention

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0016] In the description of the present invention, it should be noted that the terms "first", "second", and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] The following describes the embodiments shown in the present invention with reference to the accompanying drawings of the specification.

[0018] Reference Figure 1, this embodiment includes a device lower housing, a device upper housing, and a sealing portion. A device interface is provided inside the device lower housing. The device lower housing is further provided with an installation opening, and the device upper housing covers the installation opening and is fixedly connected to the device lower housing. A plurality of first grooves are provided in the installation opening. Correspondingly, a second groove is also provided in the device upper housing, and the first groove and the second groove form an annular groove. The sealing portion includes a sealing gasket, a plurality of wire-passing waterproof rings, and a plug. The plug is integrally formed with the sealing gasket through a connecting portion. Due to the existence of the connecting portion, the plug can move within a certain range and will not be lost during use. The sealing gasket and the wire-passing waterproof rings are integrally formed. The sealing portion is made of tensile wire silicone. The density gasket is arranged between the device lower housing and the device upper housing. The wire-passing waterproof rings are embedded in the annular groove. The device upper housing covers the installation opening and forms a seal by squeezing the sealing gasket and the wire-passing waterproof rings. The wire-passing waterproof rings have through holes for the cables to pass through. When a certain interface is not in use, the corresponding wire-passing waterproof ring does not need to pass through the cable, and the through hole can be blocked by the plug.

[0019] In order to obtain a better sealing effect, the sealing gasket and the wire-passing waterproof rings are connected to form a complete annular seal. At least one annular protrusion can also be provided on the sealing gasket. In this way, when the device upper housing and the device lower housing are installed and the annular protrusion is squeezed, a better sealing effect can be obtained, and a waterproof structure of IP54 can be achieved. The first groove and the second groove are also provided with installation card slots. Correspondingly, the wire-passing waterproof rings are provided with installation convex rings, and the installation convex rings are embedded in the installation card slots, which is convenient for positioning during installation.

[0020] The sealing portion is further provided with fixing posts and positioning plugs. Fixing grooves corresponding to the fixing posts are provided on the device lower housing, and the fixing posts are embedded in the fixing grooves, which can prevent the sealing portion from separating from the device lower housing during disassembly and causing the loss of the sealing portion. At the same time, the device lower housing is also provided with positioning holes corresponding to the positioning plugs for positioning when installing the sealing portion.

[0021] During installation, first insert the positioning plug of the sealing portion into the positioning hole of the device lower housing, then embed the fixing posts of the sealing portion into the fixing grooves of the device lower housing, and then arrange the sealing gasket of the sealing portion. Then start wiring, pass the cable through the wire-passing waterproof rings and connect it to the interface on the wiring board. If the wire-passing waterproof rings that are not needed can have their corresponding plugs block the through holes, which can achieve the effects of waterproofing and aesthetics. Finally, install the device upper housing, squeeze the sealing gasket with the device lower housing, so as to form a complete seal with the device lower housing. Since the connector is located inside the device lower housing, the cable can be effectively prevented from being maliciously unplugged by people.

[0022] It should be understood that the above specific embodiments of the present utility model are only for illustrative explanation or interpretation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
