The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0026] Embodiment 1: A chassis assembly of an aerial work vehicle with a photovoltaic unit, comprising a chassis assembly 1, a wheel 2 is installed at the bottom of the chassis assembly 1, photovoltaic units 3 are symmetrically installed on the left and right sides of the chassis assembly 1, and synchronous storage mechanisms are respectively installed at the front end and the rear end of the same photovoltaic unit 3, and the two synchronous storage mechanisms cooperate to control the inclination angle of the photovoltaic unit 3 at the current position. The two synchronous storage mechanisms are respectively fixedly installed on the front end surface and the rear end surface of the frame 101 of the chassis assembly 1, and each of the photovoltaic units 3 is arranged with its light absorbing surface facing the side of the frame 101 at the corresponding position in the storage state, and the light absorbing surface of each of the photovoltaic units 3 is in a horizontal setting state in the working state, and each of the photovoltaic units 3 is electrically connected to a storage unit fixedly installed on the rear end surface of the frame 101. When it is necessary to utilize the photovoltaic unit 3 to realize photovoltaic power generation and energy storage, the synchronous movement of the two synchronous storage mechanisms coaxially arranged at both ends of the current photovoltaic unit 3 can effectively ensure the inclination state of the light-absorbing surface of the photovoltaic unit 3, thereby effectively ensuring the angle between the photovoltaic unit 3 and the light, and ensuring the power generation efficiency; after the photovoltaic unit 3 generates electricity, the electric energy can be stored inside the power storage unit for subsequent use by the whole vehicle equipment.

[0027] In any of the above schemes, it is preferred that the photovoltaic unit 3 includes a positioning shaft 6 horizontally arranged on one side of the frame 101, the front and rear ends of the positioning shaft 6 are respectively hinged in the positioning ear seats 7 at corresponding positions, the inner ends of the positioning ear seats 7 are fixedly mounted on the corresponding side walls of the frame 101, a swing frame 7 is hinged on the outer side wall of the positioning shaft 6 between the two positioning ear seats 7, a photovoltaic panel 9 is fixedly mounted in the photovoltaic mounting cavity 8 of the swing frame 7, and the connection terminals of the photovoltaic panel 9 are electrically connected to the battery 5. The photovoltaic unit 3 adopts an end hinged method, and when used, it can quickly complete the rapid conversion between the storage state and the use state by cooperating with the synchronous storage mechanism. When in the storage state, the tension of the synchronous storage mechanism can ensure that the entire photovoltaic unit 3 is stably fixed on the corresponding end face of the current frame 101.

[0028] In any of the above schemes, it is preferred that the synchronous storage mechanism includes a servo motor 12 fixedly mounted on the corresponding end face of the frame 101, a rope drum 13 fixedly mounted on the motor shaft of the servo motor 12, a steel wire rope 14 wound on the outer side wall of the rope drum 13, the inner end of the steel wire rope 14 fixed on the motor shaft of the servo motor 12, and the outer end of the steel wire rope 14 fixedly mounted on the end of the connecting shaft 15 at the free end of the swing frame 7. When the synchronous storage mechanism is working, it mainly relies on the rotation of the servo motor 12 to drive the rope drum 13 on its motor shaft to complete the rotation. When the rope drum 13 rotates, the corresponding swing frame 7 can be driven to swing by the tension or relaxation of the steel wire rope 14, thereby achieving the purpose of quickly controlling the tilt angle of the entire photovoltaic unit 3.

[0029] Embodiment 2: A chassis assembly of an aerial work vehicle with a photovoltaic unit, comprising a chassis assembly 1, a wheel 2 is installed at the bottom of the chassis assembly 1, photovoltaic units 3 are symmetrically installed on the left and right sides of the chassis assembly 1, and synchronous storage mechanisms are respectively installed at the front end and the rear end of the same photovoltaic unit 3, and the two synchronous storage mechanisms cooperate to control the inclination angle of the photovoltaic unit 3 at the current position. The two synchronous storage mechanisms are respectively fixedly installed on the front end surface and the rear end surface of the frame 101 of the chassis assembly 1, and each of the photovoltaic units 3 is arranged with its light absorbing surface facing the side of the frame 101 at the corresponding position in the storage state, and the light absorbing surface of each of the photovoltaic units 3 is in a horizontal setting state in the working state, and each of the photovoltaic units 3 is electrically connected to a storage unit fixedly installed on the rear end surface of the frame 101.

[0030] In any of the above schemes, it is preferred that the power storage unit includes a support frame 4 bolted to the rear end surface of the frame 101, and a battery 5 is fixedly installed on the top of the support frame 4, and the battery 5 is electrically connected to each of the photovoltaic units 3.

[0031] The power storage unit in this solution can rely on the battery 5 to quickly store the electricity generated by photovoltaic power generation, ensuring that it is used for the subsequent operation of the aerial work vehicle.

[0032] In any of the above schemes, it is preferred that the photovoltaic unit 3 includes a positioning long axis 6 horizontally arranged on one side of the frame 101, and the front and rear ends of the positioning long axis 6 are respectively hinged in the positioning ear seats 7 at corresponding positions, and the inner ends of each positioning ear seat 7 are fixedly mounted on the corresponding side wall of the frame 101, and a swing frame 7 is hinged on the outer side wall of the positioning long axis 6 between the two positioning ear seats 7, and a photovoltaic panel 9 is fixedly mounted in the photovoltaic mounting cavity 8 of the swing frame 7, and the wiring terminals of the photovoltaic panel 9 are electrically connected to the battery 5.

[0033] It should be noted that the photovoltaic unit 3 designed in the utility model adopts an end-hinged method, and when used in conjunction with a synchronous storage mechanism, it can quickly complete the rapid conversion of its storage state and use state. When in the storage state, the tightening of the synchronous storage mechanism can ensure that the entire photovoltaic unit 3 is stably fixed on the corresponding end face of the current frame 101.

[0034] In any of the above solutions, it is preferred that a scratch-resistant steel plate 11 is fixedly installed in the protective cavity 10 of the swing frame 7 , and the photovoltaic installation cavity 8 is arranged opposite to the protective cavity 10 .

[0035] The anti-scratch steel plate 11 installed here can serve as the outer facade of the photovoltaic unit 3 when the entire swing frame 7 is in the storage state, and play a role in protecting the internal photovoltaic panels 9, effectively ensuring anti-scratch and protection during the driving of the aerial work vehicle.

[0036] In any of the above schemes, it is preferred that the synchronous storage mechanism includes a servo motor 12 fixedly mounted on the corresponding end face of the frame 101, a rope drum 13 is fixedly mounted on the motor shaft of the servo motor 12, a steel wire rope 14 is wound on the outer wall of the rope drum 13, the inner end of the steel wire rope 14 is fixed on the motor shaft of the servo motor 12, and the outer end of the steel wire rope 14 is fixedly mounted on the end of the connecting shaft 15 at the free end of the swing frame 7.

[0037] It should be noted that when the synchronous storage mechanism is working, it mainly relies on the rotation of the servo motor 12 to drive the rope drum 13 on its motor shaft to complete the rotation. When the rope drum 13 rotates, the tensioning or loosening of the wire rope 14 can be used to drive the corresponding swing frame 7 to swing, thereby achieving the purpose of quickly controlling the tilt angle of the entire photovoltaic unit 3.

[0038] In addition, when the photovoltaic unit 3 needs to be stored vertically, the upper end of the swing frame 7 can be tightened and brought close to a vertical state by tightening the steel wire rope 14. Through the power-off self-locking of the servo motor 12, the swing frame 7 can be tightened and abutted against the corresponding side of the frame 101 and the stability of the swing frame 7 can be maintained.

[0039] In any of the above solutions, it is preferred that the steel wire ropes 14 wound around the two coaxially arranged rope drums 13 are in a synchronous motion state in the working state.

[0040] The synchronous movement of the steel wire rope 14 can ensure that the current photovoltaic unit 3 can be smoothly swung and displaced when it is swung.

[0041] In any of the above schemes, it is preferred that a locking bolt 17 is screwed into the internal thread of the locking cavity 16 arranged on the swing frame 7 on one side of the photovoltaic installation cavity 8, and buffer springs 18 are fixedly installed on both sides of the top of the locking bolt 17, and when the photovoltaic unit 3 is in the storage state, the two buffer springs 18 are used to abut against the side wall on the corresponding side of the frame 101.

[0042] Considering that the steel wire rope 14 of the photovoltaic unit 3 and the photovoltaic panel 9 inside are in a vertically stored state, they will be vibrated by the bumps of the road surface when following the aerial work vehicle. Therefore, the buffer spring 18 is used to abut against the side of the corresponding frame 101 to control the upper end of the entire swing frame 7 to maintain elastic support, effectively playing a buffering role and avoiding damage caused by direct rigid impact.

[0043] Specific working principle: The chassis assembly of the aerial work vehicle with photovoltaic units can rely on the four wheels 2 at the bottom of the chassis assembly 1 to ensure the stability of the entire structure. When the photovoltaic unit 3 is needed to realize photovoltaic power generation and energy storage, the synchronous movement of the two synchronous storage mechanisms coaxially arranged at both ends of the current photovoltaic unit 3 can effectively ensure the inclination state of the light-absorbing surface of the photovoltaic unit 3. Therefore, the angle between the photovoltaic unit 3 and the light can be effectively guaranteed, thereby ensuring the power generation efficiency.

[0044] When the entire aerial work vehicle is in a driving state, in order to reduce the width of the entire vehicle, the corresponding photovoltaic unit 3 can be quickly stored using a synchronous storage mechanism to ensure the protection of the photovoltaic unit 3 during driving; when the photovoltaic unit 3 is in a vertical or nearly vertical storage state, the scratch-resistant steel plate 11 can be used to complete the external protection; after the photovoltaic unit 3 generates electricity, the electricity can be stored inside the storage unit for subsequent use by the vehicle equipment. When the photovoltaic unit 3 needs to be stored vertically, the upper end of the swing frame 7 can be tightened and made close to the vertical state by tightening the steel wire rope 14, and the swing frame 7 can be tightened to abut against the corresponding side of the frame 101 and maintain the stability of the swing frame 7 through the power-off self-locking of the servo motor 12.

[0045] From the above, it can be seen that the two additional photovoltaic units 3 configured on the aerial work vehicle chassis assembly 1 designed in the utility model can provide photovoltaic power supply for the entire aerial work vehicle as needed, effectively realize the hybrid power supply of new energy and original power, and facilitate the completion of energy supply during outdoor operations; the photovoltaic unit 3 can realize the rapid conversion of the work station between the vertical storage state and the light receiving working state under the action of the corresponding synchronous storage mechanism, so as to effectively ensure that the photovoltaic unit 3 in the storage state does not affect the normal driving of the entire aerial work vehicle, and at the same time, when the aerial work vehicle is idle or working outdoors, the photovoltaic units 3 on both sides can be used to complete photovoltaic power generation; each group of synchronous storage mechanisms cooperates with each other to quickly control the effective swing or locking of the photovoltaic unit 3, ensure the reasonable control of the inclination angle of the photovoltaic unit 3, and effectively ensure the photovoltaic panel 9 thereon The effect of receiving light.

Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents.
