Technical Field

[0001] This utility model relates to the technical field of wireless information transmission, specifically to a spectrum mapping device. Background Technology

[0002] A spectrum is a diagram showing the frequency distribution of electromagnetic waves. In physics and engineering, the spectrum is a way to describe the frequency components of a signal, displaying the intensity or amplitude of different frequency components. A spectrum can be continuous or discrete, depending on the characteristics of the signal. In different fields, the spectrum has different applications and meanings.

[0003] Spectrum mapping is a technical process involving the measurement and analysis of the radio spectrum to create maps of spectrum usage. Spectrum mapping techniques acquire measurements containing geographic location information and reconstruct complete spectrum maps using spatial interpolation or other data processing methods. This allows for a visual understanding of the spectrum situation within the measurement area, further enabling analysis and prediction of the overall spectrum situation and future development trends.

[0004] Existing spectrum mapping equipment is usually mounted on drones using a mounting connection method. However, this connection method does not provide a good fixation effect during the operation of the drone and the spectrum mapping equipment. As a result, the spectrum mapping equipment is easy to fall off the drone if it encounters external force during flight.

[0005] To address this, a spectrum mapping device is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a spectrum mapping device. By installing a lifting mechanism inside the housing to fix the drone connection device, the device and the drone connection device are fixedly connected. This prevents the spectrum mapping device from falling off the drone during movement due to unstable connection, which could cause damage or loss to the device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A spectrum mapping device includes a main unit enclosed in a housing. A lifting mechanism for clamping and fixing a drone connection device is located at the rear of the housing. The lifting mechanism is situated in a hollow groove inside the housing, with the bottom of the hollow groove fixedly connected to the bottom of the lifting mechanism.

[0009] Preferably, the lifting mechanism includes a small cylinder, which is sleeved with a large cylinder. A cover plate is fixedly installed above the large cylinder. The small cylinder and the large cylinder are hollow inside. A spring is installed at the hollow positions of the small cylinder and the large cylinder. One end of the spring is fixedly connected to the bottom surface of the hollow groove, and the other end of the spring is fixedly connected to the cover plate.

[0010] Preferably, a chute is provided on the outside of the small cylinder. There is a certain distance from the top of the chute to the top of the small cylinder. A slider is fixedly installed below the inside of the large cylinder. The slider is installed inside the chute and moves up and down in the chute.

[0011] Preferably, the cross-section of the hollow groove inside the housing is larger than the cross-section of the cover plate, and the cover plate moves synchronously with the large cylinder.

[0012] Preferably, there are two chutes, which are symmetrically arranged along the center line of the small cylinder on the outside of the small cylinder. There are two sliders, which are symmetrically arranged along the center line of the large cylinder inside the large cylinder. The center points of the large cylinder, the small cylinder and the cover plate are on the same straight line.

[0013] Preferably, the cross-section of the chute is in the shape of a "convex", and the cross-section of the slider is in the shape of a "convex". The cross-section of the chute is larger than the cross-section of the slider.

[0014] Preferably, the housing further includes an antenna installed on the housing and a device switch installed at the lower left corner of the front of the housing.

[0026] The technical solutions of the present utility model will now be described with reference to the accompanying drawings of the embodiments. The embodiments described below 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 skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 7 This utility model provides a spectrum mapping device, the technical solution of which is as follows:

[0028] like Figure 1-3 As shown, a spectrum mapping device includes a main unit 1, which is enclosed by a housing 2. A lifting mechanism 3 for clamping and securing a UAV connection device is located at the rear of the housing 2. The lifting mechanism 3 is situated within a hollow groove 21 inside the housing 2, with the bottom surface of the hollow groove 21 fixedly connected to the bottom of the lifting mechanism 3. The lifting mechanism 3 is used to clamp and secure the UAV connection device. The lifting mechanism 3 includes a small cylinder 31, a large cylinder 32, a cover plate 33, and springs 34 installed inside the small cylinder 31 and the large cylinder 32. When the cover plate 33 is not subjected to external pressure, it is on the same plane as the housing 2. Figure 4As shown. A small cylinder 31 is fitted with a large cylinder 32. A cover plate 33 is fixedly installed on the top of the large cylinder 32. The interiors of the small cylinder 31 and the large cylinder 32 are hollow. A spring 34 is installed in the hollow part of the interior of the small cylinder 31 and the large cylinder 32. One end of the spring 34 is fixedly connected to the bottom surface of the hollow groove 21, and the other end is fixedly connected to the cover plate 33. A sliding groove 311 is opened on the outside of the small cylinder 31. A certain distance is left between the top of the sliding groove 311 and the top of the small cylinder 31. A slider 321 is fixedly installed in the lower part of the interior of the large cylinder 32. The slider 321 is installed inside the sliding groove 311 and moves up and down in the sliding groove 311. There are two sliding grooves 311, which are symmetrically arranged on the outside of the small cylinder 31 along the center line of the small cylinder 31; as shown. Figure 6-7 As shown, there are two sliders 321. Slider 321 are symmetrically arranged inside the large cylinder 32 along its centerline. The center points of the large cylinder 32, the small cylinder 31, and the cover plate 33 are on a straight line. The cross-section of the groove 311 is convex, and the cross-section of the slider 321 is also convex. The cross-section of the groove 311 is larger than that of the slider 321. The slider 321 is installed inside the groove 311, allowing it to move freely up and down within the groove 311.

[0029] The cross-section of the hollow groove 21 inside the shell 2 is larger than the cross-section of the cover plate 33. The cover plate 33 moves synchronously with the large cylinder 32. The cover plate 33 is a circular plate. The outer ring of the cover plate 33 is also wrapped with a layer of elastic material. When the drone's connection device enters the lifting mechanism 3, it is more conducive to clamping and fixing the connection device. The elastic material can also be rubber, etc.

[0030] When the cover plate 33 is subjected to downward pressure, it causes the large cylinder 32 and the internal spring 34 to move downward together. When the pressure on the cover plate 33 is removed, the force generated by the spring 34 returning the large cylinder 32 and the cover plate 33 to their original positions, with the cover plate 33 and the housing 2 on the same horizontal plane. Since the slide groove 311 is a certain distance from the top of the small cylinder 31, the spring 34 can be prevented from over-returning during its return, thus preventing unnecessary damage to the large cylinder 32 and the cover plate 33, and preventing the cover plate 33 from exceeding the horizontal height of the housing 2. In addition, the lifting mechanism 3 can also be composed of a cube or cuboid. The spectrum mapping equipment of this application also includes an antenna 4 installed on the upper end of the housing 2 and a device switch 5 located in the lower left corner of the front of the housing 2.

[0031] In practical applications, when connecting the UAV and the spectrum mapping equipment via a connecting device, first press the cover plate 33 on the back of the housing 2. When the cover plate 33 is subjected to downward pressure, it drives the cover plate 33 and the large cylinder 32 to move the internal spring 3433 downward. The large cylinder 32 and the small cylinder 31 are movably connected by a slider 321. The slider 321 inside the lower part of the large cylinder 32 is installed in the groove 311 outside the small cylinder 31. When subjected to downward pressure, the slider 321 moves downward along the groove 311. The lower end of the small cylinder 31 is fixedly installed in the hollow groove 21 inside the housing 2. The outer periphery of both the large cylinder 32 and the small cylinder 31 is hollow, and the cross-section of the hollow part is larger than the cross-section of the cover plate 33. When the cover plate 33 is pressed down, the hollow portion of the hollow groove 21 inside the housing 2 is exposed. At this time, the drone's connecting device is placed into the hollow portion of the hollow groove 21, with the tail end of the connecting device positioned under the cover plate 33. The pressure on the cover plate 33 is then released, and the compressed spring 34 immediately rebounds, generating an upward force. This upward force from the spring 34 drives the large cylinder 32311 upward. To prevent excessive force from the spring 34 rebounding, the slider 321 inside the large cylinder 32, when sliding to the top of the external groove 311 of the small cylinder 31, will resist the excessive force of the spring 34 rebounding, allowing the cover plate 33 to return to its original position, maintaining the same level as the housing 2. Additionally, the cover plate 33 is surrounded by a ring of elastic material, which further facilitates the clamping and fixing of the connecting device. The elastic material can be rubber, etc.

Those skilled in the art will be able to make various changes, modifications, substitutions and alterations to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
