Description

Technical Field

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

[0002] As a core component of the vehicle networking system, the vehicle TBOX terminal undertakes the critical functions of vehicle data acquisition, transmission, and remote control command reception, and needs to operate stably for extended periods in complex environments such as vehicle vibration, dust, and moisture. Existing vehicle TBOX terminals suffer from the following technical challenges: Poor interface connection stability: During vehicle operation, continuous vibration will occur. The existing terminal interface is divided into a data interface and a power interface. The power interface is connected to the power plug through multiple connecting pins, and the connection is relatively tight. However, the data cable interface mostly adopts a conventional single connecting pin plug-in structure, which lacks an effective fastening mechanism. This can easily cause the data cable end to loosen from the interface connector, resulting in data transmission interruption or command delay. To address the aforementioned issues, a vehicle TBOX terminal with a secure interface needs to be designed to meet the requirements of vehicle networking systems for terminal stability and reliability. Utility Model Content

The protective shell is provided with a fastening component, which can be used to fasten the data cable end when it is inserted into the inner side of the protective shell and connected to the connector.

[0005] Preferably, the back plate has a through first socket and a second socket.

[0006] Preferably, the outer side of the protective shell is fixedly fitted with a first rubber sleeve, and the first rubber sleeve is in contact with the inner wall of the first insertion hole.

[0007] Preferably, a second rubber sleeve is fixedly fitted on the outer side of the power interface, and the second rubber sleeve is in contact with the inner wall of the second socket.

[0008] Preferably, an mounting strip is fixedly installed on the outer side of the housing. The mounting strip is U-shaped and has a through mounting hole.

[0009] Preferably, the fastening assembly includes a fixing block and an elastic sheet. The fixing block is fixedly installed on the outside of the protective shell.

Detailed Implementation

[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 1-3 The vehicle TBOX terminal with a protective structure shown includes a housing 1, a backplate 11 installed on the outside of the housing 1, a motherboard installed inside the housing 1, and multiple data interface components 2 and power interfaces 3 installed on the motherboard, and the multiple data interface components 2 and power interfaces 3 are all arranged through the backplate 11. The data interface component 2 includes a protective shell 21 and a connector 22 located inside the protective shell 21. A fastening component 23 is provided on the protective shell 21. When the data cable end is inserted into the inner side of the protective shell 21 and connected to the connector 22, the fastening component 23 can be used to fasten the data cable end.

[0017] By setting a fastening component 23 in the data interface component 2, when the data cable end is inserted into the protective shell 21 and connected to the connector 22, the elastic piece 234 in the slot 232 can exert a squeezing force on the data cable end through elastic deformation, thus initially achieving fastening. If the elastic piece 234 experiences slight metal fatigue after long-term use, resulting in a deterioration in the fastening effect, the knob at the end of the screw 235 can be rotated to drive the sliding strip 233 to slide in the slot 232, adjusting the squeezing force of the elastic piece 234. The limiting block at one end of the screw 235 can prevent the sliding strip 233 from disengaging, effectively solving the problem of data cable loosening caused by vehicle vibration and ensuring the continuity of data transmission.

[0018] like Figures 2-3 As shown, the back plate 11 has a through first socket 12 and a second socket 13.

[0019] The outer side of the protective shell 21 is fixedly fitted with a first rubber sleeve 24, and the first rubber sleeve 24 is in contact with the inner wall of the first insertion hole 12.

[0020] The power interface 3 is fixedly fitted with a second rubber sleeve 31 on the outside, and the second rubber sleeve 31 fits against the inner wall of the second socket 13.

[0021] A first rubber sleeve 24 is fitted over the outer side of the protective shell 21 of the data interface component 2, and the first rubber sleeve 24 fits tightly against the inner wall of the first socket 12 of the back plate 11; a second rubber sleeve 31 is fitted over the outer side of the power interface 3, and the second rubber sleeve 31 fits tightly against the inner wall of the second socket 13 of the back plate 11. This structure can prevent dust and moisture from entering the terminal through the socket gaps, avoid corrosion of the metal contacts of the connector 22 and the power interface 3, and significantly improve the environmental adaptability and service life of the terminal.

[0022] like Figure 1 As shown, an mounting strip 14 is fixedly installed on the outer side of the outer casing 1. The mounting strip 14 is U-shaped and has a through mounting hole.

[0023] like Figure 4 As shown, the fastening component 23 includes a fixing block 231 and an elastic piece 234. The fixing block 231 is fixedly installed on the outside of the protective shell 21. A slot 232 is provided between the fixing block 231 and the outside of the protective shell 21. The elastic piece 234 is disposed in the slot 232. When the data cable end is inserted into the protective shell 21, it contacts the elastic piece 234, and the elastic piece 234 undergoes elastic deformation and squeezes and fixes the data cable end.

[0024] The interior of the slot 232 is provided with a sliding strip 233, and the two ends of the elastic piece 234 are fixedly connected to the two ends of the sliding strip 233 respectively.

[0025] A lead screw 235 is rotatably connected to the fixed block 231. The lead screw 235 is threadedly connected to the sliding bar 233. A limit block is fixedly provided at one end of the lead screw 235, and a knob is fixedly connected to the other end of the lead screw 235.

[0026] Working principle: The operator uses the U-shaped mounting strip 14 on the outside of the outer casing 1 and the through mounting hole on the mounting strip 14 to fix the entire vehicle TBOX terminal to the preset installation position on the vehicle, thus completing the mechanical fixation of the terminal.

[0027] First, insert the external data cable end into the protective shell 21 of the data interface component 2 to make electrical connection between the data cable end and the connector 22 inside the protective shell 21; During the insertion of the data cable end, it contacts and squeezes the elastic piece 234 in the slot 232. The elastic piece 234 undergoes elastic deformation, generating a reverse squeezing force on the data cable end, thus initially securing the data cable. If further adjustment of the tightness is required, the knob at the end of the lead screw 235 on the fixing block 231 can be rotated. When the lead screw 235 rotates, it drives the sliding strip 233, which is threaded to it, to slide along the axis of the lead screw 235 in the slot 232. The sliding strip 233 simultaneously drives the two ends of the elastic piece 234 to move, thereby changing the degree of deformation of the elastic piece 234 and adjusting its squeezing force on the data cable end until a stable tightness is achieved. The limiting block at one end of the lead screw 235 can prevent the sliding strip 233 from detaching from the lead screw 235.

[0028] Insert the external power cable into the power interface 3 to complete the power supply connection of the terminal. At this time, the first rubber sleeve 24 on the outside of the protective shell 21 is tightly fitted with the inner wall of the first socket 12 of the back plate 11, and the second rubber sleeve 31 on the outside of the power interface 3 is tightly fitted with the inner wall of the second socket 13 of the back plate 11, forming a double sealing structure to prevent external dust and moisture from entering.

[0029] 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.
