Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted terminal technology, specifically a Beidou intelligent vehicle-mounted terminal. Background Technology

[0002] The BeiDou Navigation Satellite System has been widely and mandatorily installed on freight vehicles in my country for real-time positioning, driving records, and remote dispatching. Existing vehicle-mounted terminals typically use multi-point bolt fixing, external brackets, or suction cup structures, requiring screwdrivers, wrenches, and other tools for disassembly and assembly, which is time-consuming. During long-distance transportation, vibrations and temperature changes can easily cause bolts to loosen and suction cups to fall off, requiring maintenance and replacement to be completed in service areas or parking lots, affecting operational efficiency. In response, terminal devices that are easier to disassemble and assemble have emerged on the market.

[0003] For example, a Beidou positioning vehicle-mounted terminal disclosed in Chinese Patent Publication No. (CN220915654U) includes a Beidou positioning vehicle-mounted terminal body. The upper surface of the Beidou positioning vehicle-mounted terminal body is provided with a heat dissipation mechanism for uniform heat dissipation. A removable first filter screen is fixed inside the heat dissipation vent. When the Beidou positioning vehicle-mounted terminal body is working, the cooling fan inside the heat dissipation frame can be started. The cooling fan draws the outside air through the second filter screen and then sends it into the air outlet plate. The air outlet plate can uniformly and quickly dissipate heat from the electronic components inside the Beidou positioning vehicle-mounted terminal body. The air flowing into the Beidou positioning vehicle-mounted terminal body is discharged through the heat dissipation vents on the left and right sides of the Beidou positioning vehicle-mounted terminal body, thereby achieving uniform heat dissipation and improving the stability during operation.

[0004] However, the vehicle terminal disassembly and assembly method mentioned in the above patent still has some shortcomings: both the threaded rod and the pin require simultaneous action of both hands, and require a certain torque and pulling force. It is difficult for a single driver to complete this at the same time while crouching next to the driver's seat, and a wrench or pliers still need to be carried in the vehicle, which cannot meet the needs for quick disassembly and assembly of the vehicle terminal.

[0024] 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.

[0025] Example 1: Please refer to Figure 1-5 The Beidou intelligent vehicle terminal in this embodiment includes an installation frame 1, characterized in that: a connecting mechanism 2 is provided on the back wall of the inner cavity of the installation frame 1, and a terminal component 3 is fixedly provided on the upper surface of the connecting mechanism 2.

[0026] Specifically, the mounting frame 1 is pre-fixed to the lower part of the truck's dashboard or the side wall of the center console by screws or adhesive.

[0027] In this embodiment, the connecting mechanism 2 includes two sets of positioning rods 21 fixedly connected to the inner wall of the inner cavity of the mounting frame 1. The outer sides of the two sets of positioning rods 21 are slidably connected to a base 22. The four corners of the upper surface of the base 22 are provided with pads 23. The inner bottom wall of the mounting frame 1 is provided with a limiting component 24 to restrict the position of the base 22. The upper surface of the base 22 is provided with a heat dissipation component 25 to dissipate heat from the terminal component 3.

[0028] It should be noted that when the base 22 is pushed to its limit position, the two slots 247 on the lower surface of the base 22 are completely aligned in space with the two grooves 241 on the bottom wall of the mounting frame.

[0029] In this embodiment, the limiting component 24 includes two sets of grooves 241 formed in the inner bottom wall of the mounting frame 1. The interior of each set of grooves 241 is rotatably connected to a rotating shaft 242. The outer side of each set of rotating shafts 242 is fixed with a clamping plate 243. The front end of each set of rotating shafts 242 is fixedly connected with a gear 244. The left and right ends of the mounting frame 1 are slidably connected with connecting rods 245. The sides of the two sets of connecting rods 245 that are close to each other are fixedly connected with racks 246. The two sets of racks 246 are respectively meshed with the two sets of gears 244.

[0030] In this embodiment, the lower surface of the base 22 is provided with slots 247 corresponding to the positions of the two sets of grooves 241.

[0031] In this embodiment, the base 22 has two sets of sliding holes on its front side, and the base 22 is slidably disposed on the outside of the two sets of positioning rods 21 through the two sets of sliding holes.

[0032] In this embodiment, the inner walls of the two sets of grooves 241 that are close to each other are fixed with limit plates 248, and the left and right sides of the mounting frame 1 are respectively provided with connecting holes for the two sets of connecting rods 245 to slide.

[0033] Specifically, the connecting rods 245 are inserted from the left and right sides of the mounting frame, and the inner ends are fixed to the racks 246. The racks 246 mesh with the gears 244 on the same side. When the two connecting rods 245 are pushed inward at the same time, the racks 246 drive the gears 244 to rotate 90 degrees. The rotating shaft 242 drives the locking plate 243 to change from horizontal to vertical. The head of the locking plate 243 enters the slot 247 and the groove 241 at the same time, forming a rigid limit and completing the locking.

[0034] In this embodiment, the heat dissipation component 25 includes several sets of air channels 251 formed on the upper surface of the base 22. An air inlet groove 252 is formed on the back of the base 22. The air inlet groove 252 is connected to the several sets of air channels 251. An opening is formed on the back of the mounting frame 1. A cooling fan 253 is embedded inside the opening. An air supply square pipe 254 is connected to the side of the opening near the base 22.

[0035] Specifically, an axial cooling fan 253 is installed on the back of the mounting frame 1. The fan inlet is equipped with a dust filter, and the outlet is connected to an air supply square tube 254. The fan 253 forces the outside cold air into the air inlet slot 252 and distributes it into each air channel 251, so that the cold air flows through the lower surface of the terminal body 31, carrying away the heat generated by the main control chip, Beidou module 33, and camera 34 during operation. Furthermore, the hot air is naturally discharged from the periphery of the terminal body 31 and the front opening of the mounting frame 1, forming a continuous directional forced convection.

[0036] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, in order to achieve the effect of Beidou smart terminal, the terminal component 3 in this embodiment includes a vehicle-mounted terminal body 31 fixedly connected to the upper surface of four sets of pads 23. The front of the vehicle-mounted terminal body 31 is provided with a display screen 32, the interior of the vehicle-mounted terminal body 31 is provided with a Beidou module 33, and the front of the vehicle-mounted terminal body 31 is fixedly connected with a camera 34.

[0037] In this embodiment, the vehicle terminal body 31 is equipped with a controller, and the controller is electrically connected to the display screen 32, the Beidou module 33 and the camera 34 through wires.

[0038] Specifically, the Beidou module 33 can acquire the vehicle's location and trajectory in real time, the camera 34 faces the driver to capture facial and eye images, and monitor fatigue, distraction and other states, the display screen 32 can display driver status prompts and alarm information locally, the controller can perform algorithm analysis on the data images from the camera 34, identify fatigue / distraction behaviors, and trigger sound and light reminders and remote reporting, and the foot 23 can raise the terminal body 31, forming a heat dissipation channel with the air duct 251 to ensure the stability of long-term continuous monitoring.

[0039] It should be noted that in this embodiment, the high-performance computing chip in the vehicle terminal body 31 is mounted on the back of the motherboard and dissipated through an aluminum heat-conducting plate. The heat generated by the chip can be directly conducted to the aluminum heat-conducting plate through the bottom, and then the heat-conducting plate can quickly dissipate the heat. This can prevent the heat generated by the chip from accumulating locally on the motherboard and having an adverse effect on other modules and cables around it.

[0040] It should be noted that this application can be used on medium-sized or medium-to-large-sized transport trucks on the market.

[0041] The working principle of the above embodiments is as follows:

[0042] (1) The mounting frame 1 is pre-fixed to the lower part of the dashboard or the side wall of the center console of the truck by screws or adhesive. Two positioning rods 21 extend horizontally from the back wall of its inner cavity to form a straight slide rail. When the base 22 is pushed to the limit position, the two slots 247 on the lower surface of the base 22 are completely aligned with the two grooves 241 on the bottom wall of the mounting frame in space. The connecting rods 245 are inserted from the left and right sides of the mounting frame, and the inner end is fixed to the rack 246. The rack 246 meshes with the gear 244 on the same side. Push the two connecting rods 245 inward at the same time. The rack 246 drives the gear 244 to rotate ninety degrees. The rotating shaft 242 drives the plate 243 to change from horizontal to vertical. The head of the plate 243 enters the slot 247 and the groove 241 at the same time to form a rigid limit and complete the locking.

[0043] When unlocking: pull the connecting rod 245 in the opposite direction, the movement of each component is opposite, the locking plate 243 returns to the horizontal and is blocked by the limiting piece 248, the lock is released, and the base 22 can be pulled out as a whole along the positioning rod 21.

[0044] (2) An axial cooling fan 253 is installed on the back of the mounting frame 1. The fan inlet is equipped with a dustproof net, and the air outlet is connected to the air supply square tube 254. The fan 253 presses the outside cold air into the air inlet slot 252 and divides it into each air channel 251, so that the cold air flows through the lower surface of the terminal body 31, and carries away the heat generated by the main control chip, Beidou module 33 and camera 34 when they are working. Furthermore, the hot air is naturally discharged from the four sides of the terminal body 31 and the front opening of the mounting frame 1, forming a continuous directional forced convection.

[0045] (3) The Beidou module 33 can acquire the vehicle's location and trajectory in real time. The camera 34 faces the driver and captures facial and eye images to monitor fatigue, distraction and other states. The display screen 32 can display driver status prompts and alarm information locally. The controller can perform algorithm analysis on the data images from the camera 34, identify fatigue / distraction behavior, and trigger sound and light reminders and remote reporting. The foot 23 can raise the terminal body 31 and form a heat dissipation channel with the air duct 251 to ensure the stability of long-term continuous monitoring.
