[0031] like Figures 1 to 5 As shown, the present invention relates to a vehicle-mounted hyperspectral imaging device, which is used to be installed on a luggage rack crossbar 1 of an automobile, and includes a base 2, a telescopic member 3, a rotation drive mechanism 4, a buffer mechanism 8, and a hyperspectral imager 5. The base 2 is used to be installed on the luggage rack crossbar 1, the bottom end of the telescopic member 3 is connected to the base 2, and can rotate relative to the base 2 in a vertical direction, the top end of the telescopic member 3 is an output end, the output end of the telescopic member 3 is installed with the rotation drive mechanism 4, the hyperspectral imager 5 is installed on the rotation drive mechanism 4, and the rotation drive mechanism 4 is used to drive the hyperspectral imager 5 to rotate;

[0032] The buffer mechanism 8 includes a primary buffer component 81 and a secondary buffer component 82. The primary buffer component 81 and the secondary buffer component 82 are used to sequentially buffer the telescopic component 3 when the telescopic component 3 is lowered from a vertical state to a horizontal state, and the secondary buffer component 82 is also used to play a buffering role between the base 2 and the telescopic component 3 when the telescopic component 3 is placed horizontally.

[0033] In the present invention, the hyperspectral imager 5 is installed on the rotary drive mechanism 4, and then the rotary drive mechanism 4 is installed on the output end of the telescopic member 3, the telescopic member 3 is rotatably connected to the base 2, and the base 2 is fixed on the luggage rack cross bar 1 of the car. When measuring in the field, the telescopic member 3 can be erected, and then the telescopic member 3 drives the rotary drive mechanism 4 and the hyperspectral imager 5 to rise, and then the rotary drive mechanism 4 can drive the hyperspectral imager 5 to rotate to complete the data acquisition of an image. At the same time, since the telescopic member 3 raises the hyperspectral imager 5, the area of ​​the collected measurement area can be increased; in addition, compared with the method of fixing the hyperspectral imager 5 by a tripod in the prior art, the present application fixes the base 2 to the luggage rack cross bar 1 on the car to realize the installation of the hyperspectral imager 5 on the car, so as to become a vehicle-mounted hyperspectral imaging device, so as to facilitate moving to various measurement points in the field and measuring. When measuring multiple points, there is no need to repeatedly set up and put away the tripod. Furthermore, by providing the primary buffer component 81 and the secondary buffer component 82, the telescopic component 3 can be buffered in sequence during the process of lowering the vertical telescopic component 3, which can facilitate the operator to quickly lower the telescopic component 3 and reduce the impact strength of the telescopic component 3 with the base 2 when it is flattened, thereby reducing the vibration of the impact transmitted to the hyperspectral imager 5, ensuring that the hyperspectral imager 5 is not easily damaged; moreover, the secondary buffer component 82 is also used to play a buffering role between the base 2 and the telescopic component 3 when the telescopic component 3 is placed horizontally, thereby reducing the shaking caused by the bumps of the car during driving and transmitting it to the hyperspectral imager 5 at the top of the telescopic component 3, preventing the hyperspectral imager 5 from being damaged, and overcoming the problem that the hyperspectral imager 5 is easily damaged due to bumps when used in a car.

[0034] In this embodiment, the base 2 includes a bottom plate 21, two side plates 22 located on both sides of the bottom plate 21 and facing each other, a front plate 23 located between the front ends of the two side plates 22, and a rear plate 24 located between the rear ends of the two side plates 22. The bottom end of the telescopic member 3 is rotatably connected between the rear ends of the two side plates 22, and a limiting notch 25 is provided on the upper part of the front plate 23 for the telescopic member 3 to fit in and be embedded in.

[0035] The bottom end of the telescopic member 3 is rotatably connected between the rear ends of the two side plates 22. At the same time, a limiting notch 25 is provided on the upper portion of the front plate 23 for the telescopic member 3 to fit in and be embedded in. That is, after the measurement is completed, the telescopic member 3 can be rotated downward and extend into the limiting notch 25, so as to ensure the stability of the telescopic member 3 when the measurement work is stopped and the car is driving, thereby ensuring the stability of the position of the hyperspectral imager 5. The limiting notch 25 is an arc-shaped notch to fit the outer side of the telescopic member 3.

[0036] Preferably, a support plate 26 is provided on the inner side of the front plate 23 along the inner edge of the limiting notch 25 to increase the area supporting the telescopic member 3, thereby ensuring stable support for the telescopic member 3 and avoiding excessive local pressure on the position where the telescopic member 3 contacts the limiting notch 25.

[0037] In this embodiment, the primary buffer component 81 includes an elastic strip 811, and a plurality of elastic strips 811 are spaced apart along the length direction between the two side panels 22, and the plurality of elastic strips 811 are located between the telescopic member 3 and the front panel 23, so that in the process of the telescopic member 3 being lowered from a vertical state to a horizontal state, the telescopic member 3 presses down the elastic strips 811 one by one, so as to gradually increase the resistance encountered by the telescopic member 3 when being lowered, and thus, when the telescopic member 3 is being lowered, the operator does not need to use too much force to support the telescopic member 3, which can reduce the burden on the operator and improve the efficiency of lowering the telescopic member 3.

[0038] Preferably, the elastic strip 811 is specifically an elastic rope, the two ends of the elastic rope are correspondingly passed through the outside of the two side plates 22, and the two ends of the elastic rope are knotted so that the two ends of the elastic rope are correspondingly limited on the two side plates 22. Furthermore, the elastic rope of the present application can adjust the tightness of the elastic rope between the two side plates 22 by adjusting the knotting position of the elastic rope, thereby adjusting the assisting force applied by the elastic rope to the telescopic member 3, which is more practical.

[0039] In this embodiment, the secondary buffer assembly 82 includes a U-shaped buffer plate 821, a guide shaft 822, an upper limit nut 823, a lower limit nut 824 and a compression spring 825. The buffer plate 821 is located above the support plate 26. Both ends of the lower end surface of the buffer plate 821 are vertically provided with guide shafts 822. The two guide shafts 822 both penetrate the support plate 26 and the base plate 21 downward in sequence, and the guide shaft 822 can move in a vertical direction relative to the base 2. The outer periphery of the guide shaft 822 is provided with a threaded section. The upper limit nut 823 and the lower limit nut 824 are both threadedly connected to the guide shaft 822. The upper limit nut 823 is located between the support plate 26 and the base plate 21, and the lower limit nut 824 is located below the base plate 21. The compression spring 825 is sleeved outside the guide shaft 822, and the compression spring 825 is located between the upper limit nut 823 and the base plate 21.

[0040] After the telescopic member 3 is lowered and enters the limiting notch 25, the telescopic member 3 can first be supported on the buffer plate 821, and at the same time, the telescopic member 3 presses down the buffer plate 821, so that the buffer plate 821 and the guide shaft 822 move downward, and presses down the compression spring 825, and the compression spring 825 gives an upward reaction force to the guide shaft 822, thereby further buffering the telescopic member 3 to avoid the telescopic member 3 from colliding with the front plate 23 and the support plate 26 of the base 2, ensuring that the telescopic member 3 is stably lowered, and reducing the generation of vibration, ensuring that the hyperspectral imager 5 on the telescopic member 3 is not easily damaged; at the same time, through the setting of the upper limit nut 823 and the lower limit nut 824, the compression amount of the compression spring 825 can be pre-adjusted by adjusting the relative distance between the upper limit nut 823 and the lower limit nut 824, and then the resistance encountered by the telescopic member 3 when supported on the buffer plate 821 can be adjusted, which is convenient for the operator to adjust the buffering effect according to needs, and has high practicality.

[0041] Furthermore, by setting up the secondary buffer assembly 82 , when the telescopic member 3 is lowered to a horizontal state and the vehicle is driving, the vibration generated by the vehicle buffer can be absorbed, thereby reducing the vibration transmitted to the hyperspectral imager 5 of the telescopic member 3 .

[0042] The vehicle-mounted hyperspectral imaging device also includes an elastic strap 9 and a hook. The two sides of the two side panels 22 facing each other are correspondingly provided with an elastic strap 9 and a hook. One end of the elastic strap 9 is fixed to the outer side of the side panel 22, and the other end of the elastic strap 9 can be connected to the hook.

[0043] By providing the elastic band 9 , the telescopic member 3 is bound after being lowered, so as to suppress the jumping of the telescopic member 3 and ensure the stability of the hyperspectral imager 5 .

[0044] In this embodiment, the front plate 23 and the rear plate 24 are correspondingly mounted on the two luggage rack cross bars 1 through the angle code 7, and the base 2 can adjust the position along the length direction of the luggage rack cross bar 1, so that the position of the hyperspectral imager 5 can be adjusted along the transverse direction of the car.

[0045] Specifically, an adjustment groove 11 is opened along the length direction on the upper part of the luggage rack cross bar 1, and limit plates 12 are extended inward on both sides of the upper opening of the adjustment groove 11, and a gap is formed between the two limit plates 12. A fixing bolt is inserted into the adjustment groove 11, and the screw head end of the fixing bolt is located in the adjustment groove 11 and can move along the adjustment groove 11. The screw section of the fixing bolt passes through the gap and penetrates one end of the angle code 7, and is fixedly connected to the angle code 7 by a fixing nut. When the fixing nut is loosened, the angle code 7 and the fixing bolt can be moved along the adjustment groove 11 to achieve the adjustment of the position of the hyperspectral imager 5. In addition, the other end of the angle code 7 is fixed to the front plate 23 or the rear plate 24 by a fixing bolt and a fixing nut.

[0046] The vehicle-mounted hyperspectral imaging device further includes a locking member 6 for limiting the rotation of the telescopic member 3 .

[0047] Specifically, the locking member 6 is a hand-tightening bolt, and an arc-shaped guide groove 27 is provided at the rear end of the side plate 22. The hand-tightening bolt passes through the arc-shaped guide groove 27 and is threadedly connected to the telescopic member 3, so that when the telescopic member 3 rotates relative to the base 2, the hand-tightening bolt is driven to move along the arc-shaped guide groove 27, and after tightening the hand-tightening bolt, the telescopic member 3 is restricted from rotating relative to the base 2.

[0048] By setting the hand-tightening bolt, when the telescopic part 3 rotates relative to the base 2, it can play a certain guiding role, making the rotation of the telescopic part 3 more stable. After tightening the hand-tightening bolt, the telescopic part 3 can be made close to the side plate 22 to limit the rotation of the telescopic part 3, so as to keep the telescopic part 3 stably upright when the vehicle-mounted hyperspectral imager 5 is measuring, ensure the smooth measurement, and after the measurement is completed, keep the telescopic part 3 horizontal and stably installed in the limiting notch 25, limit the vibration of the telescopic part 3 due to the bumps when the car is driving, and ensure that the hyperspectral imager 5 is stable in position and not easily damaged.

[0049] In this embodiment, the base 2 is made of metal material, which may be aluminum alloy material or stainless steel material to ensure the stability of the base 2 . Weight-reducing holes are opened on the bottom plate 21 to reduce the weight of the base 2 .

[0050] In this embodiment, the telescopic member 3 is an electric lever, so that the lifting operation of the hyperspectral imager 5 is more convenient and the measurement efficiency is improved.

[0051] In this embodiment, the rotation driving mechanism 4 includes a rotation motor, and the hyperspectral imager 5 is fixed to the output end of the rotation motor, so that the hyperspectral imager 5 can rotate automatically, thereby improving the measurement efficiency.

[0052] In summary, compared with the prior art, the vehicle-mounted hyperspectral imaging device of the present invention cancels the traditional method of using a tripod as a support, and transforms it into a vehicle-mounted hyperspectral imaging device by installing the hyperspectral imager 5 on the luggage rack crossbar 1 on the top of the car, thereby reducing the work of field measurement, improving the efficiency of measurement, and also allowing a larger measurement area.

[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
