Examples

Fig. 1 is a schematic structural diagram of a heavy truck power exchange station according to an embodiment of the present utility model. The embodiment can be suitable for the condition of replacing the power of the heavy truck.

As shown in fig. 1, the system includes: the vehicle comprises a battery compartment 100, a motor changing robot 200, a traffic lane 300 and a target parking area 400 arranged on the traffic lane 300; the power exchanging robot 200 moves in a direction parallel to the traffic lane 300 and has a first power exchanging position and a second power exchanging position in the direction of the traffic lane 300; a first deceleration strip 410 perpendicular to the traffic lane is provided in the target parking area 400; the first power changing position is a position where the power changing robot 200 performs power changing operation when the front wheel of the heavy truck contacts with the first deceleration strip 410; the second power change position is a position where the power change robot 200 performs power change operation when the front wheel of the heavy truck is separated from the first deceleration strip 410; the distance between the second power exchanging position and the first power exchanging position is equal to the distance separating the front wheel of the heavy truck from the first speed reducing belt 410.

Wherein the power conversion robot 200 is movable in a direction parallel to the traffic lane 300. The battery exchange robot 200 is used to exchange batteries for a battery exchange heavy truck. Alternatively, the power exchanging robot 200 may be a movable power exchanging robot, that is, the power exchanging robot 200 itself may be provided with a movable mechanism such as a pulley. Illustratively, the heavy-duty power-exchanging truck is provided with a battery shortage, the battery compartment 100 is provided with a battery full, the battery of the heavy-duty power-exchanging truck can be replaced to the battery compartment 100 through the power-exchanging robot 200, and the battery with the battery full is selected from the battery compartment 100 to be replaced to the heavy-duty power-exchanging truck. The battery compartment 100 is used to provide full battery for a heavy truck. Optionally, a plurality of full-charge batteries are disposed in the battery compartment 100. The roadway 300 is used to provide a driving area for a heavy truck. The traffic lane 300 is provided with a target parking area 400. The target parking area 400 may be an area where a heavy truck is powered down for power conversion. The target parking area 400 may be within a battery-change range of the battery-change robot 200. Alternatively, the target parking area 400 may be determined according to a movable range of the robot. After the heavy truck for power change is driven into the target parking area 400, the power change robot 200 may change power for the heavy truck to be power changed.

A first deceleration strip 410 perpendicular to the traffic lane may be provided within the target parking area 400. The first deceleration strip 410 may be used to determine the parking position of the heavy truck. The structure of the single deceleration strip is that the middle part has a certain height, and the two sides have downward slopes. The friction force on the surface of the deceleration strip is large, so that the parking of the heavy truck with the electricity replaced can be realized conveniently. Optionally, the speed reducing belt can also be a speed reducing groove, but the speed reducing belt can be connected through bolts relative to the speed reducing groove, so that the speed reducing belt is more beneficial to disassembly and replacement. Alternatively, as shown in fig. 2, the front wheel of the heavy truck may be stopped at a position in contact with the first speed bump 410. Accordingly, the battery-powered robot 200 has a first battery-powered position in the direction of the lane 300. The first power change position is a position where the power change robot performs power change operation when the front wheel of the heavy truck contacts with the first deceleration strip 410. It should be noted that, in the case of only the first speed reducing zone 410, the driver of the heavy truck may make the heavy truck slide slowly until contacting the first speed reducing zone 410 after the heavy truck enters the target parking area 400, and immediately step on the brake to stop the heavy truck, or set the traffic lane 300 to a smaller gradient to make the heavy truck slide to the first speed reducing zone 410 and stop automatically. In order to reduce the power exchanging difficulty of the driving user, optionally, as shown in fig. 3, the front wheel of the heavy truck for power exchanging may also be stopped at a position separated from the first speed reducing belt 410, so long as the heavy truck for power exchanging is stopped in the target parking area 400, the power exchanging may also be completed by moving the power exchanging robot 200 to a corresponding position, that is, the power exchanging robot 200 further has a second power exchanging position, where the power exchanging robot performs the power exchanging operation when the front wheel of the heavy truck is separated from the first speed reducing belt 410. The distance between the second power exchanging position and the first power exchanging position is equal to the distance between the front wheel of the heavy truck and the first speed reducing belt. Thus, when the front wheel of the power exchanging heavy truck is in contact with the first deceleration strip 410, the first power exchanging position of the power exchanging robot 200 can be directly determined; meanwhile, when the front wheel of the power-exchanging heavy truck is separated from the first speed-reducing belt 410, the second power-exchanging position of the power-exchanging robot 200 may be directly determined according to the distance between the front wheel of the heavy truck and the first speed-reducing belt 410.

Optionally, as shown in fig. 4, a second deceleration strip 420 is further disposed in the target parking area 400; as shown in fig. 5, the cross-sectional area of the second speed bump 420 is equal to or less than the cross-sectional area of the first speed bump 410, and the distance between the second speed bump 420 and the rear wheel of the heavy truck is equal to or less than the distance between the first speed bump 410 and the rear wheel of the heavy truck.

A second deceleration strip 420 is further provided in the target parking area 400, and a positioning groove may be formed by the first deceleration strip 410 and the second deceleration strip 420. The positioning groove can be used for fixing the parking position of the heavy truck. The first deceleration strip 410 is used to catch the front side of the front wheel of a heavy truck. The second deceleration strip 420 is used for clamping the rear side of the front wheel of the heavy truck, and driving the heavy truck into the positioning groove. For example, the park position of the heavy truck may include the front wheel position of the heavy truck. The battery of the heavy-duty truck is a back-type battery, and the relative position is arranged between the front wheel of the heavy-duty truck and the battery, so that the position of the front wheel of the heavy-duty truck is determined, which is equivalent to the position of the battery of the heavy-duty truck. The heavy truck with the power change continuously runs, so that after the front wheels enter the positioning groove, a driving user steps on the brake, and therefore the parking positions of the heavy truck with the power change each time are all on the same line, and the robot 200 with the power change conveniently performs positioning and grabbing on the battery with the power shortage. The distance between the second speed bump 420 and the rear wheel of the heavy truck is smaller than or equal to the distance between the first speed bump 410 and the rear wheel of the heavy truck, and it can be understood that, in the driving direction of the heavy truck, the first speed bump 410 is located in front of the second speed bump 420, that is, the heavy truck passes through the second speed bump 420 first and then passes through the first speed bump 410. The smaller the cross-sectional area of the speed bump, the easier the heavy truck is to drive over the speed bump. The cross-sectional area of the second deceleration strip 420 is smaller than or equal to the cross-sectional area of the first deceleration strip 410, so that the convenience of driving the heavy truck into the positioning groove can be improved while the first deceleration strip 410 and the second deceleration strip 420 can clamp the front wheel of the heavy truck. Alternatively, the distance between the first and second speed bump 410, 420 may be determined according to the tire diameter of the heavy truck. For example, the diameter of the tire of the heavy truck may be 20 inches and the distance between the first speed bump 410 and the second speed bump 420 may be 250mm.

According to the scheme, the first deceleration strip and the second deceleration strip are arranged in the target parking area, the parking position of the heavy truck with electricity changing is fixed, the randomness of the heavy truck with electricity changing and parking is reduced, the electricity changing time is shortened, the electricity changing efficiency is improved, the cross section area of the second deceleration strip is smaller than or equal to that of the first deceleration strip, the distance between the second deceleration strip and the rear wheel of the heavy truck is smaller than or equal to that between the first deceleration strip and the rear wheel of the heavy truck, the parking stability of the heavy truck with electricity changing is improved on one hand, and the convenience of the heavy truck with electricity changing when driving into the positioning groove is guaranteed on the other hand.

Optionally, as shown in fig. 6, a third deceleration strip 430 is further disposed in the target parking area 400; as shown in fig. 7, the distance between the third speed bump 430 and the rear wheel of the heavy truck is equal to or less than the distance between the second speed bump 420 and the rear wheel of the heavy truck.

The distance between the third speed bump 430 and the rear wheel of the heavy truck is smaller than or equal to the distance between the second speed bump 420 and the rear wheel of the heavy truck, and it can be understood that, in the driving direction of the heavy truck, the second speed bump 420 is located in front of the third speed bump 430, that is, the heavy truck passes through the third speed bump 430 first and then passes through the second speed bump 420. The third deceleration strip 430 is used to indicate the position of the second deceleration strip 420. After the driving user of the heavy truck enters the power conversion station, the heavy truck jolts when passing through the third deceleration strip 430, and the driving user is prompted to reach the second deceleration strip 420, so that the driving user is prompted to decelerate and prepare for parking, and the driving user is stopped in a positioning slot between the first deceleration strip 410 and the second deceleration strip 420.

According to the scheme, the third deceleration strip is further arranged in the target parking area, the distance between the third deceleration strip and the rear wheel of the heavy truck is smaller than or equal to the distance between the second deceleration strip and the rear wheel of the heavy truck, so that jolt reminding of power-off and parking of the heavy truck is realized, and convenience in parking of a driving user is further improved.

Alternatively, as shown in fig. 7, the cross-sectional area of the third speed bump 430 is equal to or smaller than the cross-sectional area of the second speed bump 420.

The cross-sectional area of the third speed bump 430 is equal to or smaller than the cross-sectional area of the second speed bump 420. Therefore, when the third deceleration strip 430 reminds the driver of the heavy truck, the jolt amplitude is not very large, so that the jolt reminding function can be realized, and the driving experience of the driver can be ensured.

According to the scheme, the cross section area of the third deceleration strip is smaller than or equal to that of the second deceleration strip, so that jolt reminding of a driving user is realized, and driving experience of the driving user is guaranteed.

As shown in fig. 4, 6 and 8, in some embodiments, the robot 200 moves in a direction parallel to the lane 300 through the moving track 500, and it is obvious that the robot 200 may also use an AGV (Automated Guided Vehicle, intelligent unmanned vehicle) as a carrier for movement, which is not described herein. The traffic lane 300 and the battery compartment 100 according to the present embodiment are located at two sides of the moving rail 500, respectively, and preferably, the moving rail 500 and the traffic lane 300 are disposed substantially in parallel. The traffic lane 300 generally refers to a lane for a vehicle to travel, and it is not necessarily required to set a clear boundary, for example, the traffic lane 300 may be a lane formed by providing a guard rail 600 on one side, or providing only a few bumps/pits or pillars, or using only the characteristics of the material itself to make the ground surface appear different colors, or the like, as long as it is possible for a driver to refer to the lane for traveling.

In a preferred embodiment, the motor changer 200 moves along the moving track 500 in a direction parallel to the traffic lane 300, the moving track 500 can be used to fix the moving path of the motor changer, set the traffic lane 300 parallel to the moving track 500 and limit the driving area of the vehicle, so as to further ensure that the moving direction of the motor changer 200 is parallel to the traffic lane 300, and improve the accuracy of the power change operation. The battery replacing robot 200 can grasp the battery with insufficient power on the heavy truck with sufficient power, replace the battery with the battery compartment 100 for charging, grasp the battery with sufficient power, and replace the battery with the heavy truck with sufficient power. The traffic lane 300 and the battery compartment 100 are respectively positioned at both sides of the moving track 500, so that the power exchanging robot 200 can conveniently exchange power of the power exchanging heavy truck.

According to the scheme, the moving track is introduced, and the accuracy of the moving direction of the power conversion robot is further improved by moving the power conversion robot in the direction parallel to the traffic lane through the moving track; the vehicle-mounted power conversion device has the advantages that the vehicle-mounted power conversion device is characterized in that the vehicle-mounted power conversion device is arranged on the vehicle-mounted power conversion device, and the vehicle-mounted power conversion device is connected with the vehicle-.

Optionally, the distance between the third speed bump 430 and the first speed bump 410 is less than or equal to the distance between the first row of wheels and the second row of wheels of the heavy truck.

The distance between the third deceleration strip 430 and the first deceleration strip 410 may be used for the duration of the third deceleration strip 430 jolt warning for driving the user for deceleration parking, and the number of times the third deceleration strip 430 jolt warning. Therefore, the distance between the third deceleration strip 430 and the first deceleration strip 410 is generally not too short or too long, so as to avoid too short a deceleration stop time or too many times of jolt warning. The distance between the third speed bump 430 and the first speed bump 410 is smaller than or equal to the distance between the first row of wheels and the second row of wheels of the heavy truck, it is understood that the first row of wheels of the heavy truck may drive through the third speed bump 430 and finally stop in the positioning slot between the first speed bump 410 and the second speed bump 420, but the second row of wheels of the heavy truck may not drive through the third speed bump 430. That is, the number of times the third deceleration strip 430 jolts reminds is 1. By way of example, the distance between the first row of wheels and the second row of wheels of the heavy truck may be 100cm. Alternatively, the distance between the third deceleration strip 430 and the first deceleration strip 410 may be greater than a preset distance. Therefore, the duration for decelerating and stopping the vehicle after the jolt reminding is not too short. The preset distance may be, for example, 30cm.

According to the scheme, the distance between the third deceleration strip 430 and the first deceleration strip 410 is smaller than or equal to the distance between the first row of wheels and the second row of wheels of the heavy truck, so that the situation that a driving user is difficult to judge the position point of deceleration parking is avoided, convenience in power changing and parking of the heavy truck is improved, and driving experience of the driving user in the power changing and parking process is also improved.

Alternatively, the first deceleration strip 410 includes a first unit deceleration strip 411 and a second unit deceleration strip 412; the second speed bump 420 includes a third unit speed bump 421 and a fourth unit speed bump 422; the third deceleration strip 430 includes a fifth unit deceleration strip 431 and a sixth unit deceleration strip 432.

Compared with the original whole speed reducing belt, the segmented speed reducing belt can save materials, reduce the material cost of the first speed reducing belt 410, the second speed reducing belt 420 and the third speed reducing belt 430, and further improve the applicability of the scheme.

According to the scheme, the guard rail and the battery-powered robot are arranged on two sides of a traffic lane, the length direction of the guard rail is parallel to the traffic lane, so that the parking range of the battery-powered heavy truck is limited on one hand, and a reference object is provided for a driving user to drive the battery-powered heavy truck on the other hand.
