The electric vehicle referred to herein as an object to be cleaned is not limited to a pure electric vehicle, but refers to any vehicle that carries a replaceable battery. For example, it may be a hybrid vehicle having a plurality of drive sources including a battery, a pure electric vehicle, or another vehicle that meets the above requirements.

It should be appreciated that in accordance with the teachings of the foregoing embodiments of the present invention, the cleaning section may be essentially comprised of two mechanical function modules, one being a motion module that provides a displacement action of the cleaning section; and the second is a cleaning module driven by the motion module and used for providing cleaning action. The displacement motion of the motion module is specifically a single lifting motion, a single translation motion, other displacement motions not mentioned, or any combination of the foregoing motions, and can be customized and arranged according to the actual application working condition or the actual arrangement space of the power exchanging station.

The respective components in the cleaning portion 100 will be explained in detail below by taking the embodiment shown in the drawings as an example.

As an example, the moving module 110 includes a traveling wheel 111 installed at the bottom of the lifting module 120 and a power source, so that its traveling function is implemented in a very convenient and versatile manner. Optionally, one or more pairs of the road wheels 111 can be set as driving wheels, and the other road wheels 111 can be used as driven wheels. In a related aspect, the relative positioning of the moving module 110 with respect to the vehicle has multiple implementation manners, and the indirect positioning can be achieved by the relative position of the vehicle with respect to the battery replacement station and the relative position of the electric vehicle chassis cleaning device with respect to the battery replacement station, the direct positioning of the electric vehicle chassis cleaning device with respect to the vehicle can also be achieved by identifying the vehicle characteristics through a sensor, and if the operation space allows, the positioning of the electric vehicle chassis cleaning device can also be manually assisted.

As still another example, the lifting module 120 includes a lifting part 121 connected to the cleaning module 130, and a lower lifting part 122 connected to the moving module 110; the vertical relative displacement between the ascending/descending section 121 and the descending section 122 can occur. For example, as an example, the lower lifting part 122 cannot be displaced in the vertical direction, and the upper lifting part 121 can be displaced in the vertical direction with respect to the lower lifting part 122. And a sensor can be further mounted on the lifting module 120 for detecting the lifting displacement and feeding back to the control part for regulation and control.

As still another example, the lifting module 120 may be integrally configured as a housing structure in which the upper lifting part 121 serves as an upper housing and the lower lifting part 122 serves as a lower housing. At this time, the lifting module 120 is also used for accommodating other elements or allowing other elements to pass through. For example, a power source of the cleaning module 130, a soil discharge pipe, a soil collection part collecting soil, and the like may be provided in the housing. Preferably, the power source of the cleaning module 130 is fixed to the lower surface of the upper case, thereby being lifted and lowered together with the cleaning module 130 while maintaining a relative height. For another example, to reduce the workload of the lifting module 120, the dust and water collecting system and the dirt collecting portion are fixed to the lower case.

Optionally, the lifting module 120 further includes a cross bracket 123, and the upper lifting part 121 and the lower lifting part 122 are respectively provided with bracket slide rails 121a and 122a, and ends of the cross bracket 123 are respectively engaged with the bracket slide rails 121a and 122a of the upper lifting part 121 and the lower lifting part 122, and convert a linear motion of the ends of the cross bracket 123 relative to the bracket slide rails 121a and 122a into a lifting motion of the upper lifting part 121 relative to the lower lifting part 122. In addition, other mechanical structures or driving methods may be used to realize the lifting function of the lifting module 120. For example, other structures such as a turret type elevating structure and a screw-nut type elevating structure may be adopted. Similarly, the power source of the lifting module 120 is usually an electric motor or hydraulic pressure, and other forms of power, such as pneumatic power, etc., can also be used.

The cleaning module in the cleaning portion 100 of the present invention will be further described with reference to fig. 5 and 6.

Optionally, the cleaning module 130 comprises: a body portion 131 movable relative to the lifting module 120, and a decontaminating member 132 disposed on the body portion 131; wherein the decontaminating member 132 can move with the movement of the main body part 131 to clean the surface of the battery changing area on the chassis. Wherein, although the desmear element 132 in the schematic is presented in the form of a brush head, it can equally be provided as other forms of element having a desmear function. For example, as another example, the decontaminating member 132 may also take the form of a cleaning cloth or the like. In addition, the cleanable objects of the decontaminating member 132 include, but are not limited to, snow and ice, sand, dust and mud, etc. stuck to the vehicle bottom.

Optionally, a spraying element 133 is further disposed on the cleaning module 130, and the spraying element 133 is used for spraying high-pressure cleaning liquid or high-pressure cleaning gas, or a high-pressure water-vapor mixture, so as to achieve especially strong cleaning for the power battery fastener position. The nozzle of the injection member 133 is connected to a high pressure air source or a high pressure water source, not shown, through an inlet pipe. As another type of example, the cleaning module 130 also includes a dust extraction sub-head for cleaning the fasteners, the dust extraction sub-head being separately configured with a power source. By using the above modes alternatively or in combination, the position of the power battery fastener can be cleaned efficiently and qualitatively. In addition, the positions of the spray elements 133 and the dust extraction sub-brush head can be set according to the normal fastening position of the battery to be replaced, in order to achieve its specific cleaning for the fastener. For example, as an example, when the fastener setting of the battery to be replaced of the electric vehicle is provided with a corresponding design standard, the spray member 133 and the dust removing sub-brush head may be arranged at a position where the cleaning module 130 is arranged to meet the specific standard. For another example, when the arrangement of the fastener of the battery to be replaced of the electric vehicle needs to be changed according to the actual situation, the spraying element 133 and the dust removing sub-brush head can be designed to have a movable function, so as to move and align the fastener according to the actual situation.

Optionally, the cleaning module 130 further comprises a dirt absorbing and/or wicking element for suctioning dirt or liquid from the chassis. For example, the dirt suction member and/or the liquid suction member may be connected to the dirt collection portion through a drain pipe provided on the main body portion 131 to provide suction force to collect dirt, muddy water or the like falling into the main body portion 131 into the dirt collection portion of the electric vehicle chassis cleaning apparatus.

As an embodiment for powering the cleaning module 130, a driving shaft 131a is further disposed on the main body portion 131, and the main body portion 131 can rotate around the driving shaft 131 a. The drive shaft 131a will be driven by the power source. For example, as mentioned in the previous embodiments, the power source may be disposed within the lower lift portion 122 in the lift module 120. The cleaning module 130 is rotatable within a designated range following the driving shaft 131 a. Optionally, as a further modification, a sensor is further provided on the body portion 131 to sense the rotation angle of the body portion 131; and the control part will control the forward or reverse rotation of the body part 131 based on the sensed rotation angle.

Optionally, the lifting device further comprises a guide post 131b arranged on the body part 131 and a guide slot 120a arranged on the lifting module 120; the body portion 131 can rotate according to the matching trajectory of the guide post 131b and the guide groove 120 a. For example, as an example, a ball-and-socket structure may be used to provide an additional pivot point for the entire body portion 131, thereby optimizing the force applied to the body portion 131. And the gimbal ball can smoothly follow the rotation of the body portion 131 by the fitting of the guide groove 120 a.

Alternatively, the driving shaft 131a is disposed at the first end of the body portion 131, and the guide post 131b is disposed away from the driving shaft 131 a.

Optionally, the scrubbing element 132 includes a plurality of sets of bristles that are spaced apart on the body portion 131, and preferably may be uniformly spaced apart on the body portion 131. And the upper surface of the main body part 131 can be provided with a certain number of holes and grooves, so that dust, muddy water and the like which are conveniently cleaned can smoothly fall into the main body part 131.

According to another aspect of the present invention, there is also provided an electric vehicle chassis cleaning method which can be applied to the electric vehicle chassis cleaning apparatus mentioned in any of the foregoing embodiments, including:

executing a positioning step S100, wherein the control part controls the moving module 110 to move the cleaning part 100 to be aligned with the position to be cleaned of the chassis; at this time, as shown in fig. 7, the moving module 110 may move the entire electric vehicle chassis cleaning apparatus 1 from all directions of the electric vehicle 2 to a position 200 below the electric vehicle chassis to be cleaned.

After reaching the target position, performing a lifting step S200, the control part controlling the lifting module 120 to lift the cleaning module 130 to contact with the chassis to-be-cleaned position; at this time, as shown in fig. 8, the cleaning module 130 of the electric vehicle chassis cleaning apparatus 1 is lifted into contact with the electric vehicle chassis cleaning position 200 to perform a subsequent cleaning process.

The cleaning step S300 is executed, and the cleaning module 130 performs a cleaning action on the electric vehicle chassis cleaning position 200. At this time, as shown in fig. 9, the cleaning module 130 performs cleaning on the electric vehicle chassis cleaning position 200 through various actions. As an example of one cleaning action given in fig. 10, the cleaning module 130 may perform the cleaning action by a rotational movement. According to practices, the vehicle-mounted power battery of the pure electric vehicle is often large, if the whole battery replacement area is required to be cleaned, the difficulty is large by only adopting the fixed brush head, the ground projection area of the fixed brush head can be inferred to be larger than the area of the power battery, the storage space of the electric vehicle chassis cleaning device is increased, and therefore the occupied area of the battery replacement station can be increased.

In addition, the cleaning step S300 may be further refined for more thorough cleaning purposes. For example, the cleaning step S300 also includes a subdivision into a plurality of steps for different locations of the cleaning chassis, as will be listed by way of example below.

For example, the cleaning step S300 includes: in the chassis brushing step S310, the control unit controls the dirt removing member 132 to brush the chassis. The desmear element 132 will now be controlled to focus cleaning of the area of the chassis where the plates are to be replaced.

For another example, the cleaning step S300 may further include a fastener brushing step S320, in which the control part controls the dust removing sub-brush head to brush the fasteners. At the moment, the electric plate fastener in the area of the chassis to be replaced with the electric plate is cleaned. Since the fasteners tend to accumulate dust and are difficult to clean, a special dust removal sub-head is required to perform the cleaning. For example, the dust sub-head may be configured with a powerful motor to achieve the cleaning effect.

In addition, a fastener flushing step S330 may be performed in which the control part controls the spray member 133 to spray high-pressure cleaning liquid or high-pressure cleaning gas to flush the fasteners. Another way of cleaning the fasteners is to carry away dust or other foreign matter by means of a jet of high pressure fluid.

Because the two cleaning modes for the fasteners have excellent cleaning effect, the cleaning modes can be used alternatively or in combination according to actual needs.

Further, the cleaning step S300 further includes: in the suction step S340, the control part controls the soil sucking member and/or the liquid sucking member to suck dust or liquid on the chassis. This allows the entire apparatus to be cleaned more cleanly.

In addition, as a supplementary step to complete the whole cleaning method, after the cleaning step S300, the method may further include: in the lowering step S400, the control unit controls the lifting module 120 to be lowered to the minimum height. And after the cleaning step S300, specifically, as after the lowering step S400, may further include: the control part controls the cleaning module 130 to move to the initial position at the homing step S500. So will be more convenient for whole electric automobile chassis cleaning device business turn over in automobile chassis's downside.

In addition, before the positioning step S100 and/or after the cleaning step S300, based on the integrity of the whole control process, the method may further include: in the standby step S600, the control unit controls the moving module 110 to move the electric vehicle chassis cleaning apparatus to the standby position.

For the cleaning method to which the foregoing steps are applied in combination, an example of a control process thereof for cleaning the chassis of the electric vehicle will be described below with reference to fig. 11. When the vehicle to be replaced does not exist, the whole chassis cleaning device of the electric automobile can be lowered to the lowest height and is parked in the replacing power station, so that the chassis cleaning device has a very compact structure and only occupies a very small space. After the vehicle to be switched is stopped and flamed out in the entering station and before the switching equipment is started, the electric vehicle chassis cleaning device 1 keeps the lowest height to travel to the bottom of the vehicle to be switched through the moving module 110, and the control part further controls the vehicle to travel until the vehicle reaches the preset working position. The lift module 120 is then activated and the cleaning module 130 is lifted a specified height until contact is made with the power change area. Thereafter, while maintaining this height, the control section controls the cleaning module 130 to operate and controls the suction/suction element to activate to start cleaning the chassis and the fasteners, respectively. Wherein, at a particular fastener cleaning location, the cleaning module 130 stops rotating, the water intake system operates, and the injection member 133 injects a high pressure gas/high pressure water/water vapor mixture. After cleaning, the vacuum suction system is shut down, after which the cleaning module 130 continues to rotate to the next fastener location and the fastener cleaning action is repeated. After the cleaning for all the fasteners and the cleaning for the chassis battery replacement area are completed, the lifting module 120 lowers the entire electric vehicle chassis cleaning device to the lowest position, the cleaning module 130 returns to the initial position, and the moving module 110 moves the entire device back to the standby position, so as to open the battery replacement operation space. The power swapping process may then begin.

An embodiment of the operation of the cleaning device will be described below with reference to the cleaning device and method in the foregoing embodiments and fig. 7 to 10. For convenience of describing the working principle, the invention will be described by taking the electric vehicle chassis cleaning device 1 with two brush heads as an example for illustrating the distribution of the electric vehicle 2, the chassis power exchanging area 210 and the chassis power exchanging area fastening pieces 220. Aiming at electric automobiles with other specifications, the electric automobile chassis cleaning device 1 can work only by replacing the brush head part.

As shown in fig. 7, the entire device can be stored or walked with a minimum volume. After the vehicle stops in a designated area in the battery replacement station, the electric vehicle chassis cleaning device 1 can travel from the electric vehicle 2 in all directions to the position below the electric vehicle chassis cleaning position 200 for cleaning. In addition, after the electric automobile 2 in the station is cleaned, the electric automobile chassis cleaning device 1 can travel out of the station to clean other vehicles waiting for replacing the battery on site, so that the battery replacing preparation is made in advance, and the service time is shortened.

As shown in fig. 8, after the electric vehicle chassis cleaning device 1 and the electric vehicle 2 are positioned, the lifting module 120 is lifted to lift the cleaning module 130 to a designated height until the bristles contact the position 200 to be cleaned of the electric vehicle chassis.

As shown in fig. 9, the control section gives an activation command to the cleaning module 130 and drives it, the suction/suction element 134 is turned on, the cleaning module 130 is rotated in the direction indicated by the arrow, the two brush heads reach the corresponding angles of the first fastening member 220, respectively, as shown in the first position of fig. 9, and then the rotation is stopped. The spray unit 133 of the cleaning module 130 is activated to spray a high pressure gas/water/gas-water mixture to flush the exposed fastener portion, and the suction/suction unit collects the swept dirt and mud water through a drain pipe into a dirt collection portion secured within the lower housing of the lifting module 120. After a predetermined length of dwell in this position, the spray head is closed and the cleaning module 130 continues to rotate to the second fastener corresponding region, as shown in the second position in FIG. 9, where the spray elements 133 aligned from another position are operated, unlike the first step. By sequentially carrying out the steps, all the fasteners on the power battery can be cleaned. And the last position in figure 9 illustrates the rotational limit positions of two cleaning modules 130.

The electric automobile chassis cleaning device 1 provided by the invention not only can intensively clean all fastener positions, but also can clearly see from fig. 10 that the cleaning area of the cleaning module 130 can cover the whole power battery and the peripheral area thereof, and can not interfere with the tire in the process of rotating the brush head.

Thereafter, after the cleaning work for the power change area is completed, the lifting module 120 is controlled to descend to the lowest position of the apparatus (as shown in fig. 1 and 2), and the cleaning module 130 is reversely rotated to be retracted to the initial position as shown in fig. 8. The electric vehicle chassis cleaning device 1 travels back to the standby position.

At this point, the cleaning process is complete.

The above examples mainly illustrate the electric vehicle chassis cleaning apparatus and the cleaning method thereof according to the present invention. Although only a few embodiments of the present invention have been described, those skilled in the art will appreciate that the present invention may be embodied in many other forms without departing from the spirit or scope thereof.
