Description

Technical Field

[0001] This utility model relates to the field of vehicle networking, and in particular to a vehicle TBOX terminal housing. Background Technology

[0002] With the development of vehicle networking technology, vehicle TBOX (Telematics Terminal Box), as a core component connecting vehicles and the cloud, needs to work in a complex environment inside the vehicle cabin or near the chassis for a long time, facing multiple challenges such as vibration, dust, moisture and temperature fluctuations.

[0003] In existing technologies, traditional TBOX terminal casings have three major problems: Firstly, the sealing structure design is simple, relying mainly on a single sealing ring at the joint of the housing to achieve a seal. After being subjected to vehicle vibration for a long time, the sealing ring is prone to loosening and displacement, causing dust and moisture to seep into the housing and damage the internal circuit components. Secondly, the assembly positioning accuracy is low. The various components of the housing (such as the bottom plate and the back plate) lack a precise positioning structure during installation, and the positions need to be repeatedly adjusted to complete the fixing, resulting in low assembly efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle TBOX terminal housing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle TBOX terminal housing, comprising: A protective housing assembly includes an outer shell and a fixing strip, the fixing strip being mounted on the inner wall of the outer shell; A sealed housing assembly includes a base plate and a back plate, which can be installed on the bottom and back of the housing, respectively. A sealing plate and a cover plate are fixedly arranged on the top of the base plate, and the sealing plate and the cover plate are respectively tightly abutted against the side and top of the fixing strip. The back plate has multiple through holes for interface insertion.

[0006] Preferably, the side of the fixing strip is provided with a sealing groove, and both sides of the sealing plate are fixedly connected with sealing strips, and the two sealing strips are respectively inserted into the two sealing grooves.

[0007] Preferably, mounting strips are fixedly fitted on both sides of the bottom of the outer shell. The mounting strips are U-shaped, and an embedding groove is formed between the inner side of the mounting strip and the bottom of the outer shell and the fixing strip. The bottom plate is in contact with the inner wall of the embedding groove.

[0008] Preferably, the mounting strip has multiple through mounting holes.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This invention provides, for example Figures 1-4 The vehicle TBOX terminal housing shown includes: The protective housing assembly 1 includes an outer shell 11 and a fixing strip 12, the fixing strip 12 being installed on the inner wall of the outer shell 11; The sealed housing assembly 2 includes a base plate 21 and a back plate 22, which can be installed on the bottom and back of the housing 11 respectively. A sealing plate 23 and a cover plate 24 are fixedly arranged on the top of the base plate 21, and the sealing plate 23 and the cover plate 24 are tightly abutted against the side and top of the fixing strip 12 respectively. The back plate 22 has a plurality of through holes 25 for interface insertion.

[0017] like Figures 2-4 As shown, a sealing groove 121 is provided on the side of the fixing strip 12, and sealing strips 231 are fixedly connected to both sides of the sealing plate 23, and the two sealing strips 231 are respectively inserted into the two sealing grooves 121.

[0018] The sealing groove 121 of the fixing strip 12 in the protective housing assembly 1 and the sealing strip 231 of the sealing plate 23 in the sealing housing assembly 2 are inserted and cooperated to form the first sealing defense line. At the same time, the sealing plate 23 and the side of the fixing strip 12 are tightly abutted, and the cover plate 24 and the top of the fixing strip 12 are tightly abutted, forming the second sealing structure. The double sealing design completely solves the problem of easy failure of the traditional single sealing ring, and can effectively prevent external impurities such as dust and moisture from entering the housing, ensuring a stable working environment for the internal components of the TBOX terminal.

[0019] Mounting strips 14 are fixedly fitted on both sides of the bottom of the outer shell 11. The mounting strips 14 are U-shaped, and an embedding groove 141 is formed between the inner side of the mounting strip 14 and the bottom of the outer shell 11 and the fixing strip 12. The bottom plate 21 is in contact with the inner wall of the embedding groove 141.

[0020] like Figure 1 As shown, the mounting strip 14 has multiple through mounting holes.

[0021] like Figures 2-4 As shown, a fixing post 13 is fixedly connected at the angle between the inner top wall and the inner side wall of the outer shell 11, and a positioning groove 131 is provided at the end of the fixing post 13.

[0022] A positioning post 26 is fixedly connected to the outer side of the back plate 22. The end of the positioning post 26 is inserted into the positioning groove 131, and the positioning post 26 is fixedly installed in the positioning groove 131 by bolts.

[0023] The U-shaped mounting strips 14 on both sides of the bottom of the outer shell 11 form an embedding groove 141. When the base plate 21 is in contact with the inner wall of the embedding groove 141, it can be directly and accurately positioned without repeated adjustments. At the same time, the fixing post 13 inside the outer shell 11 is inserted into the positioning post 26 of the back plate 22 through the positioning groove 131, providing a clear benchmark for the installation of the back plate 22. The connection accuracy is further ensured by bolt fixing.

[0024] The U-shaped mounting strip 14 not only provides positioning but also wraps around the bottom sides of the outer casing 11, enhancing the structural strength of the bottom of the outer casing 11. The bolted connection between the fixing post 13 and the positioning post 26 increases the connection strength between the back plate 22 and the outer casing 11, effectively resisting bumps and vibrations during vehicle operation and preventing the casing components from loosening. In addition, the multi-layered bonding structure of the fixing strip 12, sealing plate 23, and cover plate 24 further strengthens the overall rigidity of the casing and extends its service life.

[0025] like Figure 1 As shown, heat dissipation grooves are provided on the outer side of the outer casing 11. The heat dissipation grooves on the outer side of the outer casing 11 increase the contact area between the casing and the air, accelerating the dissipation of heat from the inside of the casing to the external environment.

[0026] Insert the base plate 21 of the pre-assembled sealed housing assembly 2 into the embedding groove 141 of the mounting strip 14, so that the base plate 21 is completely fitted with the inner wall of the embedding groove 141, thereby positioning the base plate 21 and the outer housing 11. At the same time, the back plate 22 of the positioning post 26 is aligned with the back of the outer housing 11, so that the end of the positioning post 26 is inserted into the positioning groove 131 of the fixing post 13, thereby achieving precise positioning of the back plate 22. Then, by passing bolts through the positioning post 26 and the fixing post 13, the back plate 22 is fixed to the back of the outer shell 11. At this time, the sealing plate 23 and the side of the fixing strip 12 are tightly abutted, the cover plate 24 and the top of the fixing strip 12 are tightly abutted, and the sealing strip 231 is completely embedded in the sealing groove 121 to form a complete sealing structure.

[0027] The sealing groove 121 of the fixing strip 12 in the protective housing assembly 1 and the sealing strip 231 of the sealing plate 23 in the sealing housing assembly 2 are inserted and cooperated to form the first sealing defense line. At the same time, the sealing plate 23 and the side of the fixing strip 12 are tightly abutted, and the cover plate 24 and the top of the fixing strip 12 are tightly abutted, forming the second sealing structure. The double sealing design completely solves the problem of easy failure of the traditional single sealing ring, and can effectively prevent external impurities such as dust and moisture from entering the housing, ensuring a stable working environment for the internal components of the TBOX terminal.

[0028] The U-shaped mounting strips 14 on both sides of the bottom of the outer shell 11 form an embedding groove 141. When the base plate 21 is in contact with the inner wall of the embedding groove 141, it can be directly and accurately positioned without repeated adjustments. At the same time, the fixing post 13 inside the outer shell 11 is inserted into the positioning post 26 of the back plate 22 through the positioning groove 131, providing a clear benchmark for the installation of the back plate 22. The connection accuracy is further ensured by bolt fixing.

[0029] The U-shaped mounting strip 14 not only provides positioning but also wraps around the bottom sides of the outer casing 11, enhancing the structural strength of the bottom of the outer casing 11. The bolted connection between the fixing post 13 and the positioning post 26 increases the connection strength between the back plate 22 and the outer casing 11, effectively resisting bumps and vibrations during vehicle operation and preventing the casing components from loosening. In addition, the multi-layered bonding structure of the fixing strip 12, sealing plate 23, and cover plate 24 further strengthens the overall rigidity of the casing and extends its service life.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
