Description

Technical Field

[0001] This utility model relates to the field of logistics technology, specifically to a logistics vehicle positioning device. Background Technology

[0002] In the field of logistics technology, logistics vehicle positioning equipment is a key device to ensure full visibility of cargo transportation and improve scheduling efficiency. It receives satellite signals in real time through internal positioning components to achieve accurate tracking of vehicle location. It is widely used in scenarios such as trunk transportation and urban distribution. In order to maintain the continuous operation of the equipment, an external power supply is required through the power supply docking point. However, the power supply docking point of the existing logistics vehicle positioning equipment mostly relies on the plug's own plug-in structure for fixation, lacking a special reinforcement and protection design.

[0003] Because logistics vehicles often face situations such as bumpy roads and accidental cable pulling during cargo loading and unloading, the power plugs that are fixed by simply plugging and unplugging are prone to loosening and falling off, causing the equipment to lose power and stop, affecting the real-time transmission of positioning data. Therefore, there is an urgent need to develop a logistics vehicle positioning device to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a logistics vehicle positioning device that solves the technical problems of easy power plug detachment and poor protection at the connection point.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a logistics vehicle positioning device, including a housing, a sealing cover fixedly connected to the top of the housing, and a positioning component for positioning the logistics vehicle inside the housing, and a power supply docking seat for supplying power to the positioning component on one side of the housing;

[0006] It also includes a plug anti-dislodgement mechanism for reinforcing and preventing the plug inside the power supply dock from falling off. The plug anti-dislodgement mechanism includes two sets of mounting seats fixed to the side of the housing near the power supply dock, with the two sets of mounting seats located above and below the power supply dock, respectively. Two sets of springs are fixed to both sides inside the mounting seats. One end of the spring is fixed to a connector that penetrates the interior of the mounting seat. One end of the connector is fixed to a docking shell. A slot is provided on one side of the docking shell to allow the plug cable to enter. A locking member extending into the interior of the connector is also threaded onto one side of the mounting seat.

[0007] Preferably, a sealing rubber gasket is fixed inside the slot on one side of the docking shell to achieve a seal between the plug cable and the slot.

[0008] Preferably, the positioning component includes a base plate fixed to the bottom of the housing, and a positioning module for positioning logistics vehicles is provided on one side of the top of the base plate.

[0009] Preferably, silicone blocks are also fixed to the four corners of the bottom of the sealing cover to abut against the four corners of the substrate for cushioning and protection.

[0010] Preferably, it further includes signal gain components disposed on both sides of the housing for enhancing the positioning signal. The signal gain components include a rotating base for providing a rotating foundation, a damping bearing seat for limiting the rotational position of the rotating base by friction, a support rod for providing a mounting position for the gain antenna, and a gain antenna for enhancing the positioning signal.

[0011] Preferably, the rotating base is rotatably mounted on the bottom of both sides of the housing, and the damping bearing seat is rotatably mounted on one side of the rotating base. The support rod is fixedly connected to one side of the damping bearing seat, and one end of the support rod is fixedly connected to one end of the gain antenna. The gain antenna is of model HX-CHX603A.

[0012] This utility model provides a positioning device for logistics vehicles. Compared with the prior art, it has the following advantages.

[0013] 1. The mounting base is used to fix the spring. Rotating the locking part can release the limit of the connector. Pulling the connector can move the docking shell away from the power supply docking base. After the power plug is inserted, the spring will elastically reset and drive the docking shell to close and clamp the plug. Then tighten the locking part to fix the position. At the same time, the sealing rubber gasket inside the docking shell will adhere to the cable and seal it. This solves the problems of traditional plugs that are easy to fall off and lose power if they are fixed by plugging and unplugging, and the problem of water and dust accumulation in the docking gap causing short circuits. This ensures stable outdoor power supply for the equipment.

[0014] 2. By rotating the base, the damping bearing seat can be driven, which in turn allows the support rod to adjust the angle of the gain antenna. The damping bearing seat locks the position of the base by its own frictional resistance, ensuring that the gain antenna maintains a stable posture. This, in conjunction with the gain antenna, enhances the satellite signal reception strength, solving the problem of positioning drift and signal loss caused by the built-in small gain antenna in complex environments, which leads to vehicle dispatching errors, and improving positioning accuracy and stability.

[0019] 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.

[0020] First implementation method:

[0021] refer to Figure 1-3 A logistics vehicle positioning device includes a housing 1, a sealing cover 102 fixedly connected to the top of the housing 1, and a positioning component for positioning the logistics vehicle is provided inside the housing 1. A power supply docking seat 1012 for supplying power to the positioning component is also provided on one side of the housing 1.

[0022] It also includes a plug anti-dislodgement mechanism 2 for reinforcing and preventing the plug inside the power supply docking seat 1012 from falling off. The plug anti-dislodgement mechanism 2 includes two sets of mounting seats 201 fixed to the side of the housing 1 near the power supply docking seat 1012, and the two sets of mounting seats 201 are respectively located above and below the power supply docking seat 1012. Two sets of springs 202 are fixed to both sides inside the mounting seat 201. One end of the spring 202 is fixed to a connector 203 that penetrates the inside of the mounting seat 201. One end of the connector 203 is fixed to a docking shell 204. A slot is provided on one side of the docking shell 204 to allow the plug cable to enter. A locking member 205 extending into the inside of the connector 203 is also threaded on one side of the mounting seat 201.

[0023] A sealing rubber gasket 206 is fixedly connected inside the slot on one side of the mating shell 204 to achieve a seal between the plug cable and the slot.

[0024] The positioning component includes a base plate 101 fixed to the bottom of the inside of the housing 1, and a positioning module 1011 for positioning logistics vehicles is provided on one side of the top of the base plate 101.

[0025] Silicone blocks 1021 are also fixed to the four corners of the bottom of the sealing cover 102 to abut against the four corners of the substrate 101 for cushioning and protection.

[0026] Working principle: Rotate the locking part 205 to make it exit from the inside of the connector 203, release the movement limit of the connector 203, pull the connector 203, and make it drive the docking shell 204 to move away from the power supply docking seat 1012. During this process, the spring 202 inside the mounting seat 201 is compressed and deformed.

[0027] After inserting the power plug into the power connector 1012, the connector 203 is released. The spring 202 drives the connector 203 to move back through the elastic restoring force. The connector 203 further drives the two sets of docking shells 204 to move towards the outside of the power plug and close. Finally, the locking piece 205 is rotated to screw it back into the connector 203, fixing the moving position of the connector 203, and then fixing the moving position of the docking shells 204, so that the docking shells 204 are fixedly limited to the outside of the power plug, realizing the anti-detachment reinforcement function of the power plug.

[0028] Meanwhile, the sealing rubber gasket 206 inside the slot of the docking shell 204 fits tightly with the plug cable, forming a waterproof and dustproof seal on the outside of the power supply docking seat 1012. This avoids the problem that the power supply plug of traditional positioning equipment relies solely on its own plugging and unplugging for fixation, which can easily fall off under vehicle bumps or cable pulling, leading to equipment power outages and shutdowns. It also solves the problem that water and dust can easily enter the gap between the power supply docking seat and the plug, thus causing short circuits and equipment failures. Ultimately, it achieves stable protection for the power supply connection and greatly improves the power supply reliability of the equipment in complex outdoor environments.

[0029] The sealing cover 102 is placed on top of the housing 1 and fixed in place. The silicone blocks 1021 at the four corners of the bottom of the sealing cover 102 simultaneously abut against the four corners of the substrate 101 to ensure that the substrate 101 is installed in a stable position. The sealing cover 102 forms a closed protection inside the housing 1 to prevent external water and dust from entering and damaging the positioning module 1011. The elastic abutment design of the silicone blocks 1021 can buffer the vibration caused by vehicle driving bumps, and avoid the problem of signal reception deviation caused by unstable installation of the positioning module 1011, which affects the positioning accuracy.

[0030] Second implementation method:

[0031] In the actual use of traditional logistics vehicle positioning equipment, due to the low gain of the built-in positioning antenna and the fixed installation angle, it is easily affected by complex environments such as signal blockage in densely populated areas of tall buildings, signal shielding in tunnels, and multiple obstacles in mountainous areas, which can lead to large positioning drift errors and intermittent signal loss. To address this, this device is also designed with a signal gain component, the structure of which and its working principle are as follows.

[0032] refer to Figure 2In the second embodiment of this utility model, a signal gain component 3 for enhancing the positioning signal is also provided on both sides of the housing 1. The signal gain component 3 includes a rotating base 301 for providing a rotating foundation, a damping bearing seat 302 for limiting the rotation position of the rotating base 301 by friction, a support rod 303 for providing an installation position for the gain antenna 304, and a gain antenna 304 for enhancing the positioning signal.

[0033] The rotating base 301 is rotatably mounted on the bottom of both sides of the housing 1, and the damping bearing seat 302 is rotatably mounted on one side of the rotating base 301. The support rod 303 is fixedly connected to one side of the damping bearing seat 302. One end of the support rod 303 is fixedly connected to one end of the gain antenna 304, and the gain antenna 304 adopts the HX-CHX603A model.

[0034] Working principle: Hold the rotating base 301 and manually rotate it to make it rotate on both sides of the bottom of the housing 1. The rotating base 301 synchronously drives the damping bearing seat 302 to rotate. The damping bearing seat 302 further drives the gain antenna 304 to adjust its angle through the support rod 303. After the gain antenna 304 is adjusted to the optimal signal receiving angle, the damping bearing seat 302 locks the position of the rotating base 301 through its own frictional resistance, ensuring that the gain antenna 304 maintains a stable posture, realizing the adjustable function of the gain antenna 304, enhancing the satellite signal receiving strength, and avoiding the problem of positioning drift and signal loss that easily occur in signal-blocked scenarios such as densely built-in small gain antennas, such as high-rise buildings, tunnels, and mountainous areas, which leads to vehicle dispatching errors.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
