Description

Technical Field

[0001] This invention relates to the field of vehicle parts technology, and more particularly to an automatically opening and closing ventilation box. Background Technology

[0002] Vehicle-mounted modular shelters are containerized equipment used in geological exploration, water conservancy projects, construction projects, and military command operations that require fieldwork and combat. Most are equipped with ventilation boxes, whose primary function is to ensure normal air exchange between the inside and outside of the vehicle, thereby guaranteeing proper air circulation. When the temperature inside the shelter is high, in addition to cooling through air conditioning, the ventilation boxes can be opened to effectively lower the temperature inside the vehicle, providing an auxiliary cooling effect. Currently, the ventilation boxes in vehicle-mounted modular shelters are generally divided into two types: air inlet boxes and air outlet boxes. Under normal circumstances, the air outlet box is installed inside the shelter. On the upper side, the air intake box is installed on the lower side of the cabin. When ventilation is needed, the air intake box door and the air exhaust box door can be opened with a special key to ensure air circulation inside and outside the vehicle. As the air intake box is low to the ground, personnel can stand on the ground to open it. However, as the air exhaust box is higher to the ground, personnel cannot open it directly from the ground. The boarding ladder needs to be hooked on the ladder hook on the lower side of the cabin, and personnel need to stand on the boarding ladder to open the air exhaust box. The operation is more complicated and cumbersome, and it is less convenient to use. Summary of the Invention

[0003] The problem solved by this invention is to provide an automatically opening and closing ventilation wall box, which has a simple structure and can be automatically opened and closed without manual operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an automatically opening and closing ventilation box, comprising a box frame, a box door, a slide rail and a support rod, wherein the box door is rotatably installed on one side of the box frame via a hinge, and slide rails are symmetrically fixed to the bottom outer wall of the box door, and support rods are slidably connected to the slide rails.

[0005] Preferably, a fixed mounting base is fixedly connected to the outer wall of one top end of the wall box frame, a turbine mounting base is fixedly connected to the outer wall of the bottom end of the fixed mounting base, a second worm pin is rotatably connected to the inner wall of one side of the turbine mounting base, a turbine is fixedly connected to the outer wall of one end of the second worm pin, a worm mounting base is fixedly connected to the outer side of the turbine mounting base, a first worm pin is rotatably connected to the bottom end of the worm mounting base, and a worm is engaged on the outer wall of the top end of the first worm pin.

[0006] Preferably, a motor mounting base is fixedly connected to the bottom outer wall of the worm gear mounting base, a DC motor is mounted at the bottom of the motor mounting base, a coupling is mounted at the top of the output shaft of the DC motor, and the bottom end of the first worm gear pin is mounted inside the coupling.

[0007] Preferably, the fixed mounting base and the motor mounting base are symmetrically provided with ribs.

[0008] Preferably, the upper end of the strut is fixedly connected to the hub of the turbine.

[0009] The beneficial effects of this invention are: simple and compact structure, low cost, and the ability of personnel to control the upper end of the support rod to rotate via a worm gear combination through voice control, thereby driving the lower end of the support rod to move up and down along the vertical groove of the slide rail, ultimately realizing the easy opening and closing of the wall box door, simplifying the opening process of the ventilation wall box, preventing rainwater from entering the cabin through the ventilation wall box in an unattended state, eliminating the trouble of personnel getting on and off the vehicle and taking and taking up the boarding ladder, and improving work efficiency.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Specific implementation examples are given below.

[0014] See Figures 1-3 An automatically opening and closing ventilation wall box includes a wall box frame 1, a wall box door 2, a slide rail 3 and a support rod 4. The wall box door 2 is rotatably installed on one side of the wall box frame 1 via a hinge. The slide rail 3 is symmetrically fixed to the bottom outer wall of the wall box door 2, and the support rod 4 is slidably connected to the slide rail 3. A fixed mounting base 5 is fixedly connected to the top outer wall of one side of the wall box frame 1. A turbine mounting base 14 is fixedly connected to the bottom outer wall of the fixed mounting base 5. A second worm pin 12 is rotatably connected to the inner wall of one side of the turbine mounting base 14. A turbine 6 is fixedly connected to the outer wall of one end of the second worm pin 12. A worm mounting base 8 is fixedly connected to the outer side of the turbine mounting base 14. A first worm pin 11 is rotatably connected to the bottom end of the worm mounting base 8. A worm 7 is meshed on the top outer wall of the first worm pin 11. When the DC motor 13 is started, the worm 7 on the first worm pin 11 is reciprocated through the coupling 10, which drives the turbine 6 to reciprocate, thereby driving the support rod 4 to reciprocate, so that the lower end of the support rod 4 can move up and down along the vertical groove of the slide rail 3. A motor mounting base 9 is fixedly connected to the bottom outer wall of the worm mounting base 8. A DC motor 13 is mounted on the bottom of the motor mounting base 9. A coupling 10 is mounted on the top of the output shaft of the DC motor 13. The bottom of the first worm pin 11 is installed inside the coupling 10. When the DC motor 13 is started, the worm 7 on the first worm pin 11 is reciprocated through the coupling 10, which facilitates the driving of the wall box door 2. Ribs are symmetrically provided on the fixed mounting base 5 and the motor mounting base 9 to reinforce the fixed mounting base 5 and the motor mounting base 9. The upper end of the strut 4 is fixedly connected to the hub of the turbine 6. When the turbine 6 rotates, the strut 4 can be adjusted and rotated by the turbine 6.

[0015] Working principle: When ventilation is required in the cabin, the DC motor 13 is started via voice control, which rotates the worm 7 on the first worm pin 11 through the coupling 10, causing the turbine 6 to rotate slightly, thereby causing the support rod 4 to rotate clockwise. This allows the lower end of the support rod 4 to move upward along the vertical groove of the slide rail 3. Under the thrust, the slide rail 3 pushes the wall box door 2 outward, thus opening the wall box door 2. Similarly, after ventilation is completed, the DC motor 13 is started via voice control, which rotates the worm 7 on the first worm pin 11 in reverse through the coupling 10, causing the turbine 6 to rotate slightly in reverse, thereby causing the support rod 4 to rotate counterclockwise. This allows the lower end of the support rod 4 to move downward along the vertical groove of the slide rail 3. Under the pull, the slide rail 3 pulls the wall box door 2 inward, thus closing the wall box door 2. The control system of the ventilation wall box mainly consists of a power supply, a voice acquisition and recognition module, a rain sensor module, a manual switch module, a signal recognition and processing module, and a motor controller. The system is powered by a 24V DC power supply, using a 24V switching power supply. Firstly, the voice acquisition and recognition module can recognize specific command words, converting voice commands into corresponding electrical signals and sending them to the signal recognition and processing module. The rain sensor module can be placed on the cabin roof, sending an electrical signal to the signal processing module when it rains outside. The signal processing module converts the electrical signals from the voice module and the rain sensor module into control signals for the motor controller. The motor controller can control the DC motor 13 to rotate forward and backward via the received signals, which, after conversion through the transmission mechanism, controls the opening and closing of the wall box door 2. Alternatively, the motor controller can be manually controlled to open and close the wall box door 2. This design allows for a simple and compact structure, low cost, and easy opening and closing of the wall box door 2 via voice control, simplifying the opening process of the ventilation wall box. In unattended operation, it prevents rainwater from entering the cabin through the ventilation wall box, eliminating the hassle of personnel getting on and off the vehicle and retrieving the boarding ladder, resulting in high work efficiency.
