Description

Technical Field

[0001] The present invention relates to the technical field of cabinets, and in particular to a vehicle control cabinet with structured high-efficiency heat dissipation. Background Art

[0002] The vehicle control cabinet is mainly used for interconnection with lane peripherals, such as barrier machines, traffic lights, etc. It has three main interfaces: switch interface, serial port and Ethernet port. The internal space of the cabinet is narrow, and there are a large number of lines inside it. Therefore, during the installation process, it is easy to cause the lines to be scattered. When the weather is hot, the inside of the cabinet is easily affected by the weather and a large amount of heat energy is easily accumulated. The various components inside the cabinet will emit a large amount of heat energy when working. If the lines are close to each other, fire is likely to occur. In addition, the scattered lines also greatly affect the subsequent disassembly of the cabinet for maintenance. Therefore, a new type of vehicle control cabinet is needed. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a vehicle control cabinet with structured high-efficiency heat dissipation, which has good heat dissipation effect and is convenient for workers to arrange the lines neatly.

[0004] The technical solution of the present invention is as follows: a structured high-efficiency heat dissipation vehicle control cabinet, comprising a cabinet shell, a line fixing device connected to the cabinet shell, a heat dissipation device connected to the cabinet shell and a controller, wherein the line fixing device comprises a plurality of sliding rails fixedly connected to the inner wall of the cabinet shell, a slider slidably connected to the sliding rails, a connecting shaft slidably connected to the slider, a positioning block fixedly connected to the connecting shaft and a wiring harness fixing bracket fixedly connected to the connecting shaft, wherein the sliding rails are arranged in sequence along the vertical direction, and the inner wall of the cabinet shell is also provided with a plurality of positioning holes evenly distributed in the cabinet shell, The central axes of the positioning holes are respectively in the same straight line with the central axes of the sliding tracks, the positioning blocks have a certain elasticity, and when the connecting shaft slides a certain distance, the positioning holes can be interference fit with the positioning blocks, the wiring harness fixing bracket is provided with a plurality of limiting spring pieces evenly distributed on the wiring harness fixing bracket, the shape enclosed by the limiting spring pieces and the inner wall of the wiring harness fixing bracket is adapted to the shape and size of the wiring harness to be fixed, the heat dissipation device includes a plurality of cooling fans connected to the inside of the cabinet shell and a temperature sensor connected to the cabinet shell, and the temperature sensor and the cooling fan are respectively electrically connected to the controller.

[0005] With the above technical solution, first, the parts to be processed are installed into the cabinet shell, and then the wiring harness is arranged. During the arrangement, the staff fixes the wiring harness to be fixed with one hand, and then slides the slider along the sliding track to a suitable position with the other hand and makes the positioning block correspond to the position of the positioning hole. Then the staff can quickly push the wiring harness fixing bracket down. After the connecting shaft is subjected to the thrust, the positioning block has a certain elasticity, so the positioning block will be inserted into the positioning hole, so that the position of the wiring harness fixing bracket is fixed, and then the wiring harness is fixed on the wiring harness fixing bracket. After the staff fixes all the wiring harnesses on the wiring harness fixing bracket in turn according to the number of wiring harnesses, the wiring harness inside the cabinet shell can be arranged neatly, which is convenient for subsequent maintenance. At the same time, it can avoid fire caused by overheating between wiring harnesses. In addition, by arranging a number of cooling fans inside the cabinet shell, when the temperature sensor senses that the temperature inside the cabinet shell reaches the threshold, the temperature sensor sends an electrical signal to the controller, and the controller controls the cooling fan to start working, thereby reducing the temperature inside the cabinet shell, ensuring that the equipment can operate normally, and improving the service life of the components inside the cabinet shell.

[0006] A further configuration of the present invention is that the wire harness fixing bracket is provided with a plurality of connection holes and cable ties connected to the connection holes, and the connection holes penetrate through the bottom of the wire harness fixing bracket.

[0007] By adopting the above technical solution, since the wire harness fixing bracket is provided with a plurality of connection holes and cable ties connected to the connection holes, and the connection holes pass through the bottom of the wire harness fixing bracket, the cable ties can occupy as little internal space of the cabinet shell as possible, and can improve the stability when the wire harness fixing bracket and the wire harness are connected together, thereby avoiding the wire harness inside the cabinet shell from becoming scattered when subjected to external vibration force.

[0008] The present invention is further configured as follows: two adjacent sliding rail brackets are provided with a plurality of positioning grooves, the cabinet shell is provided with a plurality of baffles slidably connected to the positioning grooves, the baffle is provided with a plurality of heat dissipation holes evenly distributed on the baffle, the two ends of the baffle are respectively slidably connected to the positioning grooves on both sides of the cabinet shell, the thickness of the baffle is adapted to the width of the positioning groove, and a baffle is provided between every two sliding rails.

[0009] By adopting the above technical solution, since two adjacent sliding rail brackets are provided with a number of positioning grooves, and a baffle is provided between every two sliding rails, and the baffle is slidably connected to the sliding rail, therefore, after the wiring harness is arranged, the baffle is slid into the positioning groove, and the wiring harness is separated in sequence in the vertical direction by the baffle, thereby further avoiding overheating caused by close contact between the wiring harnesses. At the same time, since the baffle is provided with heat dissipation holes, the air circulation inside the cabinet shell can be further improved, avoiding the problem of poor heat dissipation caused by heat energy accumulation between the wiring harnesses.

[0010] A further configuration of the present invention is that a fixing groove is provided on the baffle, and the heat dissipation fan is fixedly connected to the fixing groove.

[0011] With the above technical solution, since the cooling fan is fixedly connected to the fixing groove, a cooling fan is provided between two adjacent sliding rails, which can further improve the heat dissipation performance inside the cabinet shell, thereby increasing the service life of the components in the cabinet.

[0012] The present invention is further configured as follows: a plurality of jet elements are provided on the wiring harness fixing bracket, an air intake pipe connected to the jet element and a cold air generator connected to the air intake pipe are provided on the jet element, the jet direction of the jet element is toward the center direction of the cabinet shell, and the cold air generator is electrically connected to the controller.

[0013] By adopting the above technical solution, when the temperature sensor senses that the temperature inside the cabinet shell exceeds the threshold value, the temperature sensor sends an electrical signal to the controller, and the controller controls the cold air generator to transmit cold air to the air intake pipe, and then transmits the cold air through the air intake pipe to the jet element and sprays it toward the center direction of the wiring harness fixing bracket, thereby reducing the overall temperature inside the cabinet shell. At the same time, the air flow inside the cabinet shell is improved, and the heat exchange efficiency inside the cabinet shell is improved, thereby protecting the components inside the cabinet shell.

[0014] Further configuration of the present invention: the baffle includes a sliding part, a limiting part connected to the sliding part and a heat dissipation part connected to the limiting part, the number of sliding parts and limiting parts on each baffle is two, the two sliding parts and the two limiting parts are symmetrically arranged with the central axis of the heat dissipation part as the axis center, the sliding part is slidably connected to the positioning groove, the limiting part has a certain elasticity, the heat dissipation holes are evenly distributed on the heat dissipation part, and the sliding part, the limiting part and the heat dissipation part are integrally formed.

[0015] By adopting the above technical solution, when installing the baffle, the two sliding parts are respectively aligned with the two positioning grooves on the inner wall of the cabinet shell and slide in. Since the limiting part is connected to the sliding part, the limiting part may contact the wiring harness and further fix the position of the wiring harness, thereby improving the stability of the wiring harness position.

[0016] The present invention is further configured as follows: a plurality of circulation connection pipes are provided inside the limiting portion, the circulation connection pipes are connected to a circulation pump, the circulation pump is connected to a water storage tank, and the controller is electrically connected to the circulation pump.

[0017] By adopting the above technical solution, when the temperature sensor senses that the temperature inside the cabinet shell exceeds the threshold value, the temperature sensor sends an electrical signal to the controller, and the controller controls the circulation pump to start working, so that the water in the water storage barrel flows through the inside of the limit part through the circulation connecting pipe, and then flows back to the inside of the water storage barrel, forming a cycle. In this way, the temperature inside the cabinet shell and the surface of the wiring harness can be absorbed, thereby further improving the heat dissipation efficiency inside the cabinet shell and protecting the components installed inside the cabinet shell.

During the arrangement, the staff fixes the wiring harness to be fixed with one hand, and then slides the slider 6 along the sliding track 5 to a suitable position with the other hand and makes the positioning block 8 correspond to the position of the positioning hole 10. Then the staff can quickly push the wiring harness fixing bracket 9 down. After the connecting shaft 7 is subjected to the thrust, the positioning block 8 has a certain elasticity, so the positioning block 8 will be inserted into the positioning hole 10, so that the position of the wiring harness fixing bracket 9 is fixed, and then the wiring harness is fixed on the wiring harness fixing bracket 9.
