Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example (b):
as shown in fig. 1 to 5, the dust removing device for the power compartment of the motor vehicle provided by the embodiment includes a sealing cover 1, a telescopic driving member 2 and a scissor type telescopic structure 3. The closed cover 1 is installed on the top end of the scissor type telescopic structure 3, one end of the telescopic driving piece 2 is fixed, and the other end of the telescopic driving piece 2 is connected with the position between the top end and the bottom end of the scissor type telescopic structure 3. The telescopic drive 2 can be extended or shortened to drive the top end of the scissor jack 3 up or down. The closed cover 1 can ascend or descend under the driving of the scissor type telescopic structure 3 and is in butt joint with the opening of the motor vehicle power compartment 4, and the closed cover 1 is used for closing the motor vehicle power compartment 4 when in butt joint with the opening of the motor vehicle power compartment 4.
As shown in fig. 2, the number of the power compartments 4 at the rear of the vehicle may be one, as shown in fig. 3, and the number of the power compartments 4 at the rear of the vehicle may be two, and the two power compartments 4 are arranged one above the other at the rear of the vehicle.
The motor vehicle can be an electric motor vehicle such as an electric bus, an electric truck and the like, and the power cabin 4 on the motor vehicle is an electric appliance cabin.
In order to be suitable for the power cabins 4 located at different heights and for the motor vehicles with the upper and lower power cabins 4 arranged at the tail of the vehicle, when the height of the sealing cover 1 from the ground needs to be changed, the telescopic driving member 2 in the dust removing device for the power cabin of the motor vehicle provided by the embodiment can be started, as shown in fig. 2-4, the telescopic driving member 2 can be extended or shortened after being started, and then the top end of the scissor type telescopic structure 3 connected with the telescopic driving member can be driven to ascend or descend. After the top end of the scissor type telescopic structure 3 ascends or descends, the closed cover 1 arranged on the top end of the scissor type telescopic structure 3 can ascend or descend, and the height of the closed cover 1 from the ground can be changed. When the closed cover 1 is positioned at a position opposite to the opening of the power compartment 4 of the motor vehicle, the closed cover 1 can be butted with the opening of the power compartment 4 of the motor vehicle, so that the power compartment 4 of the motor vehicle can be closed.
Because the scissors type telescopic structure 3 is connected between the closed cover 1 and the telescopic driving member 2 in the dust removing device for the power compartment of the motor vehicle provided by the embodiment, the rising or falling process of the closed cover 1 is realized under the driving of the scissors type telescopic structure 3 directly connected with the closed cover, the rising or falling process of the closed cover 1 is mainly realized by the rising or falling process of the top end of the scissors type telescopic structure 3, but not completely realized by the telescopic process of the telescopic driving member 2.
The telescopic drive 2 provided in this embodiment may be an existing hydraulic cylinder, such as a piston cylinder.
Compared with the prior art, the direct component for supporting the enclosure 1 and driving the enclosure 1 to ascend and descend in the dust removing device for the power compartment of the motor vehicle provided by the embodiment is the scissor type telescopic structure 3 instead of the telescopic driving member 2, and even when the power compartment 4 is located at a higher position, in order to drive the enclosure 1 to a position opposite to the position of the power compartment 4, the telescopic driving member 2 is not required to output a longer stroke. Therefore, the telescopic driving member 2 in the dust removing device for the power compartment of the motor vehicle provided by the embodiment does not need to adopt a special hydraulic cylinder, and the cost is lower.
It can be seen that the dust collector for the power compartment of the motor vehicle provided by the embodiment alleviates the technical problem that when the power compartment 4 is located at a higher position in the prior art, the reciprocating motion range of the lifting hydraulic cylinder needs to be larger in order to drive the dust collection cover to the position opposite to the power compartment 4, so that the existing dust collector for the power compartment of the motor vehicle has higher requirements on the output pressure of the hydraulic cylinder and the moving stroke of the hydraulic cylinder, and a special hydraulic cylinder, such as a plunger hydraulic cylinder, needs to be adopted, thereby resulting in higher cost of the lifting assembly.
As shown in fig. 2-3, the dust removing device for the power compartment of the motor vehicle provided by the embodiment further comprises a dust blowing assembly 5 and a dust sucking assembly 6. A dust blowing assembly 5 is arranged inside the closed cover 1, and the dust blowing assembly 5 is used for blowing away dust in the power compartment 4 of the motor vehicle. The dust suction assembly 6 is communicated with the closed cover 1 through a pipeline, and the dust suction assembly 6 is used for sucking blown dust in the power compartment 4 of the motor vehicle.
When the dust removing device for the motor vehicle power compartment is used for removing dust of the motor vehicle power compartment 4, the top end of the scissor type telescopic assembly can be driven to ascend or descend by the telescopic driving piece 2, and then the height of the closed cover 1 from the ground is changed, so that the closed cover 1 is located at a position opposite to the position of the motor vehicle power compartment 4. The enclosure 1 can then be moved horizontally so that the enclosure 1 is docked with the opening of the vehicle's power compartment 4. After the closed cover 1 is butted with the opening of the power compartment 4 of the motor vehicle, a closed space is formed between the closed cover 1 and the power compartment 4 of the motor vehicle. Then, the dust blowing assembly 5 can be started, and the dust blowing assembly 5 can blow off dust attached to devices such as electric appliances or internal combustion engines in the power compartment 4 of the motor vehicle or dust attached to the inner wall of the power compartment 4. After the dust in the motor vehicle power compartment 4 is blown off, the dust collection assembly 6 is started, and the dust collection assembly 6 can absorb the blown-off dust in the motor vehicle power compartment 4 to the outside of the closed cover 1, so that the whole dust collection process of the motor vehicle power compartment 4 can be completed.
In addition, compared with the process that the lifting component in the motor vehicle power compartment dust removal device in the prior art needs to drive the supporting platform, the nozzle, the mechanical arm, the dust collection cover and the dust collector to lift together, the telescopic driving piece 2 and the scissor type telescopic structure 3 in the motor vehicle power compartment dust removal device provided by the embodiment only need to drive the sealing cover 1 to lift, and do not need to drive the sealing cover 1, the dust blowing component 5 and the dust collection component 6 to lift together. Therefore, the pressure applied to the telescopic driving member 2 and the scissor type telescopic structure 3 in the dust removing device for the power compartment of the motor vehicle provided by the embodiment is small, the output power of the telescopic driving member 2 is small, and the requirement on the telescopic driving member 2 can be further reduced.
As shown in fig. 4-8, the dust removing device for the power compartment of the motor vehicle provided in this embodiment further includes a chassis 7, and both the scissor type telescopic structure 3 and the telescopic driving member 2 are mounted on the chassis 7.
The chassis 7 is used for supporting the scissor type telescopic structure 3 and the telescopic driving piece 2, and the scissor type telescopic structure 3 and the telescopic driving piece 2 can be integrated together by the chassis 7, so that unified management and integral movement of the dust removal device for the power compartment of the motor vehicle are facilitated.
As shown in fig. 2 and 3, the suction assembly 6 is located on one side of the scissor mechanism 3 and is mounted on the chassis 7.
When the dust collection assembly 6 is also arranged on the chassis 7, the chassis 7 can integrate the scissor type telescopic structure 3, the telescopic driving piece 2 and the dust collection assembly 6 together, so that unified management and integral movement of the dust collection device for the power compartment of the motor vehicle can be further facilitated.
As shown in fig. 6-8, the dust removing device for the power compartment of the motor vehicle provided by the present embodiment further includes a plurality of rollers 70, and the plurality of rollers 70 are installed below the chassis 7.
The rollers 70 are used for converting the friction between the chassis 7 and the ground into rolling friction, thereby facilitating the movement of the motor vehicle power compartment dust removing device on the ground and the movement of the enclosure 1 in the motor vehicle power compartment dust removing device to a position opposite to the position of the motor vehicle power compartment 4.
Further, the roller 70 may be a directional wheel or a universal wheel.
When the chassis 7 is driven to steer in order to enable the closed cover 1 on the chassis 7 to be accurately butted with the power compartment 4 of the motor vehicle, the closed cover 1, the dust blowing assembly 5 and the dust suction assembly 6 on the chassis 7 are heavy, so that great manpower is consumed in the steering process of the chassis 7.
In order to facilitate steering of the drive chassis 7, the present embodiment preferably includes a plurality of wheels 70 under the chassis 7, at least one of the wheels 70 being a motor-driven steering wheel. The electric steering wheel can be driven by electric power to steer, so that the chassis 7 in the moving process can be driven to steer. The chassis 7 can greatly save labor and labor by utilizing electric power to steer, and the labor intensity of workers is reduced.
In order to facilitate the control of the operation state of the electric steering wheel by the operator, it is preferable that a handle 71 is provided on the chassis 7, the handle 71 is connected with the electric steering wheel, and a button for controlling the operation of the electric steering wheel is provided on the handle 71.
As shown in fig. 8, the dust removing device for the power compartment of the motor vehicle provided in this embodiment further includes a control box 8, a switch assembly and a power supply are disposed in the control box 8, the switch assembly is used for controlling the operation of the dust blowing assembly 5 and the dust collecting assembly 6, and the power supply is used for supplying power to the dust blowing assembly 5 and the dust collecting assembly 6. The control box 8 is fixed on the dust collection assembly 6.
The switch assembly can be a control panel or a physical button, a knob and the like. The switch assembly is arranged on the control box 8, so that workers can control the dust removal device of the power compartment of the motor vehicle to remove dust conveniently.
The control box 8 is fixed on the dust collection component 6, so that all parts in the motor vehicle power compartment dust removal device can be further integrated together, the convenience of managing and using the motor vehicle power compartment dust removal device is improved, the area of the top surface of the chassis 7 can be saved, and the occupied space of the chassis 7 is further reduced.
As shown in figure 8, when the control box 8 is fixed on the dust suction assembly 6, the pipeline communicated between the dust suction assembly 6 and the closed cover 1 can pass through the control box 8 and then is communicated with the dust suction assembly 6.
It can be seen that the control box 8 not only protects the power supply for powering the dust blowing assembly 5 and the dust collection assembly 6, but also protects a portion of the ducting between the dust collection assembly 6 and the enclosure 1.
As shown in fig. 3, 4, 6 and 7, the scissor type telescopic structure 3 includes a plurality of support rod groups 30, and the plurality of support rod groups 30 are sequentially hinged in a vertical direction. Each support rod group 30 comprises four support rods 300 and a connecting rod 301, the middle parts of two support rods 300 in the four support rods 300 are rotatably connected with one end of the connecting rod 301, and the middle parts of the other two support rods 300 are rotatably connected with the other end of the connecting rod 301.
Wherein, the top ends of the four support rods 300 in the support rod group 30 close to the closed cover 1 are slidably connected to the bottom end of the closed cover 1, and the bottom ends of the four support rods 300 in the support rod group 30 close to the chassis 7 are slidably connected to the chassis 7. The fixed end of the telescopic driving member 2 is fixed on the chassis 7, and the end of the telescopic driving member 2 far away from the chassis 7 is connected with the connecting rod 301 in any one of the support rod sets 30.
After the telescopic driving member 2 extends, one end of the telescopic driving member 2, which is far away from the chassis 7, can drive the connecting rod 301 to rise, and the connecting rod 301 can drive the supporting rod 300 in the supporting rod group 30 to rotate after rising, so that the overall height of the supporting rod group 30 is increased, and further, the whole scissor type telescopic structure 3 can extend, and the top end of the scissor type telescopic structure 3 rises. When the top end of the scissor jack 3 is raised, the enclosure 1 may be driven by the scissor jack 3 to rise.
After the telescopic driving member 2 is shortened, one end of the telescopic driving member 2, which is far away from the chassis 7, can drive the connecting rod 301 to descend, and the connecting rod 301 can drive the supporting rod 300 in the supporting rod group 30 to rotate after descending, so that the overall height of the supporting rod group 30 is reduced, the whole scissor type telescopic structure 3 can be shortened, and the top end of the scissor type telescopic structure 3 is descended. When the top end of the scissor jack 3 is lowered, the enclosure 1 may be driven to lower by the scissor jack 3.
Because the connecting rod 301 of any one of the supporting rod sets 30 is connected to one end of the telescopic driving member 2 away from the chassis 7, the end of the telescopic driving member 2 away from the chassis 7 is lower than the top end of the scissor type telescopic structure 3, and the dust removing device for the power compartment of the motor vehicle provided by this embodiment does not need the telescopic driving member 2 to have a large reciprocating range.
As shown in fig. 6 and 7, the dust removing device for the power compartment of the motor vehicle provided by the present embodiment may further include a top plate 9, wherein the top plate 9 is mounted on the bottom end of the enclosure 1, and the top ends of the four support rods 300 in the support rod group 30 adjacent to the enclosure 1 are slidably connected to the bottom surface of the top plate 9.
Wherein, the bottom surface of the top plate 9 may be provided with a sliding slot, and the top ends of the four support rods 300 in the support rod group 30 close to the enclosure 1 are slidably connected in the sliding slot on the bottom surface of the top plate 9. Correspondingly, the chassis 7 may also be provided with a sliding slot, and the bottom ends of the four support rods 300 in the support rod group 30 close to the chassis 7 are slidably connected in the sliding slot on the chassis 7.
In order to reduce the requirement for the reciprocating stroke of the telescopic driving member 2 and to stably support the sealing cover 1, the number of the support rod sets 30 is preferably two in this embodiment.
In order to enable the scissor type telescopic structure 3 to stably support the enclosure 1, one end of the telescopic driving member 2 far away from the chassis 7 may be fixedly connected with the connecting rod 301 in any one of the supporting rod sets 30.
Also in order to enable the scissor jack 3 to stably support the enclosure 1, the end of the telescopic drive 2 remote from the chassis 7 may be connected to the connecting rod 301 of the support rod group 30 of the two support rod groups 30 close to the enclosure 1.
As shown in fig. 2 and 3, the dust blowing assembly 5 includes an air source, an air pump and a nozzle 50, and the air source, the air pump and the nozzle 50 are sequentially communicated through a pipe.
The gas source may be a high pressure gas source, and the gas pump may pump gas from the gas source to the showerhead 50. After the gas is sprayed out from the spray nozzle 50, an airflow is formed, and the airflow can blow off dust attached to the inner wall of the power compartment 4 of the motor vehicle and dust attached to devices such as electric appliances or internal combustion engines in the power compartment 4 of the motor vehicle. At the moment, because the closed cover 1 is butted with the opening of the power compartment 4 of the motor vehicle, a closed space is formed between the closed cover 1 and the power compartment 4 of the motor vehicle, dust blown off from the power compartment 4 of the motor vehicle cannot fly out to the outside, and the outside environment cannot be polluted.
