Description

Technical Field

[0001] This utility model relates to the field of mobile communication vehicle technology, and in particular to a photovoltaic panel retraction structure for a communication vehicle. Background Technology

[0002] Mobile communication vehicles provide communication functions in emergency rescue and outdoor activities. Existing mobile communication vehicles have built-in batteries to provide long-term power support for the communication equipment on the vehicle. However, battery power alone often has a short range. To improve the range of mobile communication vehicles, some communication vehicles are equipped with photovoltaic panels to utilize outdoor solar energy for power generation. Existing communication vehicles with photovoltaic panels, as shown in patent application number CN201720071867.5, include a communication vehicle body and a solar panel. The solar panel is installed at an angle on the upper side of the communication vehicle body. The solar panels of existing communication vehicles cannot rotate around the z-axis. In order to achieve better solar power generation, it is often necessary to adjust the direction of the communication vehicle body so that the solar panel can be aligned with the sun. In addition, the solar panels of existing communication vehicles are mounted on the upper side of the communication vehicle body by brackets. When the communication vehicle is in motion, the solar panels have poor stability and are easily shaken off the upper part of the brackets. Or, when the communication vehicle is traveling at high speed, the solar panels are easily damaged by high-speed airflow. Utility Model Content

[0003] To address the shortcomings of existing communication vehicle solar panels, such as their inability to rotate around the z-axis and poor stability, this invention proposes a photovoltaic panel retraction and adjustment structure for communication vehicles. This structure enables the solar panels to rotate around the z-axis and improves their stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A photovoltaic panel retraction and adjustment structure for a communication vehicle includes a communication vehicle body, a photovoltaic panel, a turntable, a rotating mechanism, a return spring, a transmitter tower, and a drive mechanism. The turntable is rotatably connected to the upper side of the communication vehicle body, and the rotating mechanism can drive the turntable to rotate around the z-axis. One end of the photovoltaic panel is hinged to the upper side of the turntable through the return spring, and the lower end of the transmitter tower is hinged to the upper side of the communication vehicle body. The drive mechanism is connected to the transmitter tower in a transmission manner. The retraction and adjustment structure has an extended state and a retracted state. In the extended state, the end of the photovoltaic panel away from the return spring is tilted upward, the transmitter tower is vertical, and it is detached from the photovoltaic panel. In the retracted state, the transmitter tower is horizontal and presses the photovoltaic panel downward to make the photovoltaic panel horizontal.

[0006] With the above settings, the rotating mechanism can drive the photovoltaic panel to rotate on the z-axis, so that the photovoltaic panel can be better aligned with the sun and improve power generation efficiency. In addition, after the retracting structure is retracted, the transmission tower flattens the photovoltaic panel, reducing wind resistance and airflow impact on the photovoltaic panel during the movement of the communication vehicle, protecting the photovoltaic panel. On the other hand, it also improves the stability of the photovoltaic panel during the movement of the communication vehicle.

[0007] Furthermore, the retractable structure also includes elastic pads, which are fixedly connected to the upper side of the turntable. In the retracted state, the elastic pads support the lower side of the photovoltaic panel.

[0008] The above settings further enhance the stability of the photovoltaic panels while the communication vehicle is in motion.

[0009] Furthermore, the photovoltaic panel includes a photovoltaic panel body, a support frame, and rollers. One end of the support frame is hinged to the turntable via a return spring. The photovoltaic panel body is mounted on the upper side of the support frame. The rollers are rotatably connected to the upper side of the support frame away from the return spring. In the retracted state, the transmission tower squeezes the rollers.

[0010] The above settings prevent the photovoltaic panels from being damaged by the transmission tower.

[0011] Furthermore, the drive mechanism includes a slider, an electric push rod, and a connecting rod. The electric push rod is located between the turntable and the transmission tower and is fixedly connected to the upper side of the communication vehicle body. The output shaft of the electric push rod faces the turntable and is fixedly connected to the slider. The connecting rod is hinged between the slider and the transmission tower. The electric push rod extends and retracts to drive the transmission tower to rotate upward or toward the photovoltaic panel.

[0012] Furthermore, the turntable has a positioning groove on its edge, and in the retracted state, the slider is embedded in the positioning groove.

[0013] The above settings further enhance the stability of the photovoltaic panels.

[0014] Furthermore, the positioning groove is V-shaped.

[0015] The above settings facilitate the sliding block's entry into the positioning slot.

[0016] Furthermore, a photoelectric sensor is installed at the end of the slider facing the turntable, and the photoelectric sensor is connected to the electric push rod.

[0017] The above settings prevent the transmission tower from damaging the photovoltaic panels. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0024] like Figures 1 to 5 A retractable photovoltaic panel adjustment structure for a communication vehicle includes a communication vehicle body 3, a photovoltaic panel 4, a turntable 5, a rotating mechanism, a return spring (not shown in the figure), a transmitter tower 7, and a drive mechanism 8. The turntable 5 is rotatably connected to the upper side of the communication vehicle body 3. The rotating mechanism can drive the turntable 5 to rotate around the z-axis. One end of the photovoltaic panel 4 is hinged to the upper side of the turntable 5 through the return spring. The lower end of the transmitter tower 7 is hinged to the upper side of the communication vehicle body 3. The drive mechanism 8 is connected to the transmitter tower 7 in a transmission connection. The retractable structure has an extended state and a retracted state. In the extended state, the end of the photovoltaic panel 4 away from the return spring is tilted upward, and the transmitter tower 7 is vertical and detached from the photovoltaic panel 4. In the retracted state, the transmitter tower 7 is horizontal and presses the photovoltaic panel 4 downward to make the photovoltaic panel 4 horizontal.

[0025] With the above settings, the rotating mechanism can drive the photovoltaic panel 4 to rotate on the z-axis, so that the photovoltaic panel 4 can be better aligned with the sun and improve power generation efficiency. In addition, after the retracting structure is retracted, the transmission tower 7 flattens the photovoltaic panel 4, reducing wind resistance and airflow impact on the photovoltaic panel 4 during the movement of the communication vehicle, protecting the photovoltaic panel 4. On the other hand, it also improves the stability of the photovoltaic panel 4 during the movement of the communication vehicle.

[0026] Specifically, the main body 3 of the communication vehicle in this application is basically a van structure. Figure 1 The communication vehicle is oriented in the front, rear, left, and right directions. A turntable 5 is horizontally connected to the upper rear end of the main body 3 of the communication vehicle. In the unfolded state, the front end of the photovoltaic panel 4 is hinged to the upper side of the turntable 5. One end of a return spring is connected to the front end of the photovoltaic panel 4, and the other end is connected to the turntable 5. Under the rigidity of the return spring, the rear end of the photovoltaic panel 4 tilts upwards, with the photovoltaic panel 4 at approximately a 30-degree angle to the horizontal plane. The rotating mechanism uses a motor to drive the turntable 5 to rotate around the z-axis, so that the photovoltaic panel 4 faces the sun. The photovoltaic panel 4 generates electricity to charge the communication vehicle's built-in battery, thereby improving the communication vehicle's communication range. The transmission tower 7 includes a tower body and a signal transceiver, located in front of the turntable 5. The lower end of the tower body is hinged to the upper side of the main body 3 of the communication vehicle, and the aforementioned signal transceiver is installed on the upper end of the tower body. The communication vehicle transmits and receives signals through the signal transceiver. When the tower body is vertical, the signal transceiver is at its highest position, increasing signal strength. After the communication vehicle completes its communication task, the rotating mechanism drives the turntable 5, and the turntable 5 rotates back to its initial position. Figure 1The lower end of the photovoltaic panel 4 is forward, and the drive mechanism 8 drives the transmission tower 7 to rotate backward. When the tower body of the transmission tower 7 contacts the upper end of the photovoltaic panel 4, the transmission tower 7 continues to rotate downward. Under the squeezing action of the transmission tower 7, the photovoltaic panel 4 rotates downward, causing the two ends of the return spring to twist relative to each other. When the photovoltaic panel 4 rotates to a horizontal position, the transmission tower 7 is horizontal, and the retracting structure switches to the retracted state. The photovoltaic panel 4 and the transmission tower 7 are close to the turntable 5 and the upper surface of the communication vehicle body 3. The communication vehicle has low wind resistance during driving, and the photovoltaic panel 4 is less affected by airflow. The photovoltaic panel 4 is more stable during the driving of the communication vehicle and is not easily damaged. Moreover, when the transmission tower 7 is horizontal, it supports the photovoltaic panel 4 downward, further improving the stability of the photovoltaic panel 4 during the driving of the communication vehicle.

[0027] As one implementation method, the retractable structure also includes an elastic pad 9, which is fixedly connected to the upper side of the turntable 5. In the retracted state, the elastic pad 9 supports the lower side of the photovoltaic panel 4.

[0028] The above settings further enhance the stability of photovoltaic panel 4 during the operation of the communication vehicle.

[0029] The elastic pad 9 in this application is specifically a rubber pad, which is set below the rear end of the photovoltaic panel 4. In the retracted state, the rubber pad supports the lower side of the photovoltaic panel 4, further improving the stability of the photovoltaic panel 4 during the movement of the communication vehicle. The elastic pad 9 has good elasticity and can absorb impact, preventing the elastic pad 9 from damaging the photovoltaic panel 4.

[0030] As one implementation, the photovoltaic panel 4 includes a photovoltaic panel body 41, a support frame 42, and a roller 43. One end of the support frame 42 is hinged to the turntable 5 through a return spring. The photovoltaic panel body 41 is mounted on the upper side of the support frame 42. The roller 43 is rotatably connected to the upper side of the end of the support frame 42 away from the return spring. In the retracted state, the transmission tower 7 squeezes the roller 43.

[0031] The above settings prevent the photovoltaic panel 4 from being damaged by the transmission tower 7.

[0032] The support frame 42 of this application is a steel structure frame with high rigidity, which wraps around and under the photovoltaic panel body 41 to protect the photovoltaic panel body 41. The roller 43 is rotatably connected to the upper rear end of the support frame 42. When the transmission tower 7 rotates backward, the tower body of the transmission tower 7 contacts the roller 43, and the photovoltaic panel 4 is pushed downward by the roller 43. The roller 43 reduces the friction between the transmission tower 7 and the photovoltaic panel 4, making the rotation of the transmission tower 7 and the photovoltaic panel 4 smoother.

[0033] As one implementation, the drive mechanism 8 includes a slider 81, an electric push rod 82, and a connecting rod 83. The electric push rod 82 is disposed between the turntable 5 and the transmission tower 7 and is fixedly connected to the upper side of the communication vehicle body 3. The output shaft of the electric push rod 82 faces the turntable 5 and is fixedly connected to the slider 81. The connecting rod 83 is hinged between the slider 81 and the transmission tower 7. The electric push rod 82 extends and retracts to drive the transmission tower 7 to rotate upward or toward the photovoltaic panel 4.

[0034] In this application, the electric push rod 82 extends forward and backward, and the slider 81 is slidably connected to the upper side of the communication vehicle body 3 via a guide rail to improve the stability of the slider 81's movement. The connecting rod 83 is inclined, with its lower end hinged to the upper side of the slider 81 and its upper end hinged to the lower end of the transmitter tower 7. When the electric push rod 82 drives the slider 81 to move toward the turntable 5, the slider 81 pulls the transmitter tower 7 to rotate backward via the connecting rod 83. When the electric push rod 82 drives the slider 81 to move forward, the transmitter tower 7 rotates upward.

[0035] As one implementation method, the turntable 5 has a positioning groove 10 on its edge, and in the retracted state, the slider 81 is embedded in the positioning groove 10.

[0036] The above settings further enhance the stability of photovoltaic panel 4.

[0037] When slider 81 is inserted into positioning groove 10, slider 81 acts as a pin to prevent turntable 5 from rotating while the communication vehicle is in motion.

[0038] As one implementation method, the positioning groove 10 is V-shaped.

[0039] The above settings facilitate the entry of slider 81 into positioning groove 10.

[0040] As one implementation method, a photoelectric sensor 11 is provided at the end of the slider 81 facing the turntable 5, and the photoelectric sensor 11 is connected to the electric push rod 82.

[0041] The above settings prevent the launch tower 7 from damaging the photovoltaic panel 4.

[0042] When the turntable 5 of this application rotates to the initial position, the positioning groove 10 is located on the front side of the turntable 5 and aligned with the slider 81. If the turntable 5 is not rotated to the correct position, the positioning groove 10 is not aligned with the slider 81. At this time, the photovoltaic panel 4 is tilted, and the electric push rod 82 drives the slider 81 to move backward. The slider 81 pulls the transmitter tower 7 to rotate backward through the connecting rod 83. After the slider 81 approaches the edge of the turntable 5, the photoelectric sensor 11 at its end detects the edge of the turntable 5 and sends a signal to the controller that controls the electric push rod 82. The controller controls the electric push rod 82 to stop moving to prevent the transmitter tower 7 from continuing to move downward and crushing the photovoltaic panel 4. The retraction structure of this application only works when the positioning groove 10 of the turntable 5 is aligned with the slider 81. The slider 81 moves backward under the action of the electric push rod 82 and enters the positioning groove 10. The photoelectric sensor 11 at its end will not detect the edge of the turntable 5 and will not contact the bottom of the positioning groove 10, thus preventing the photoelectric sensor 11 from being crushed.

[0043] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
