Description

Technical Field

[0001] The present invention relates to the technical field of mining equipment, and in particular, to a vehicle attitude adjustment system and a vehicle attitude adjustment method. Background Art

[0002] With the increasing consumption of non-renewable resources, especially oil resources, people have to think about the sustainable development of the automotive industry. New energy vehicles will become the mainstream of automotive development in the first few decades of the new century, which has become the consensus of all insiders in the automotive industry.

[0003] Commercial vehicles include trailers, mining trucks, light trucks, heavy trucks, etc. When in use, commercial vehicles consume a large amount of fuel, so the usage cost is very high. However, the use of new energy can greatly reduce its usage cost, so commercial vehicles are also gradually trending towards the new energy field.

[0004] Although the use of new energy vehicles can greatly reduce the usage cost of the project, the subsequent problem is the charging problem of new energy vehicles. In remote areas such as mining areas and forest areas, building a separate battery swapping station for construction vehicles is a large project. Especially in mining areas, based on requirements such as regulations and standards, the approval of the infrastructure construction and power grid installation of the battery swapping station is difficult and costly. Along with the mining of the mining area, the actual construction location will gradually move away from the original battery swapping station location. Construction vehicles need to move along with the progress of the project, and the distance for them to return to the fixed charging station for charging is gradually lengthened, resulting in waste of energy during the battery swapping process. Moreover, excessive construction of battery swapping stations will cause damage to the environment.

[0005] A movable battery swapping station can reduce the energy waste generated by vehicles due to long-distance round-trip charging. However, such a movable charging station needs to be parked on a platform, which is used to provide a flat bearing surface and fix the battery swapping equipment.

[0006] Currently, most of the methods for providing a flat bearing surface are to install multiple oil cylinders on both sides of similar engineering hoisting vehicles. After the multiple oil cylinders extend downward, the vehicle is lifted and then fixed on the bottom surface. In similar prior arts, there is a method of one-key controlling the extension of multiple oil cylinders. However, in most cases, this method makes the extension length of each oil cylinder reach the maximum length. This requires the vehicle to park on a relatively flat road surface to indirectly make the vehicle level, that is, to make the vehicle body in a horizontal state. Otherwise, the extension lengths of its multiple oil cylinders need to be corrected one by one to make the vehicle level, which is time-consuming and laborious.

[0007] Therefore, the above problems need to be solved urgently. Summary of the Invention

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] Please refer to Figures 1 to 3, in this embodiment, a vehicle attitude adjustment system for adjusting a vehicle 100 parked on a platform to a preset attitude is proposed. The vehicle attitude adjustment system includes a controller, an attitude detector, a plurality of support members 1 and a plurality of stroke detectors 2. The attitude detector is configured to detect the current attitude information of the vehicle 100. The stroke detectors 2 are arranged at different parts of the vehicle 100, and each support member 1 has a support end 13 that can extend and support on the platform to cooperate with lifting the vehicle 100. The controller is configured to obtain the current attitude information provided by the attitude adjustment member, compare the current attitude information with the preset attitude, so as to judge the specified stroke that each support end 13 should extend, and the controller is further configured to control the extension stroke of each support end 13. The plurality of stroke detectors 2 are electrically connected to the controller, and the plurality of stroke detectors 2 are respectively configured to detect the extension stroke of the support end 13 of each support member 1.

[0044] It can be understood that when the vehicle 100 is parked on any platform, the attitude detector feeds back the current attitude information of the vehicle 100 to the controller. When the controller receives the current attitude information of the vehicle 100, it compares the current attitude information with the preset attitude information and controls the support end 13 of the support member 1 to extend to cooperate with lifting the vehicle 100. In the whole process, there is no need for too much manual intervention, and the vehicle 100 can be quickly adjusted to the preset attitude according to different working environments, so as to improve the power exchange efficiency of the power exchange equipment.

[0045] It is worth noting that the controller is preferably a PLC controller (programmable logic controller). The PLC controller and its use are prior arts and are not the technical solutions to be protected in this embodiment, so no further description will be given here.

[0046] It is also worth noting that the preset attitude of the vehicle 100 can be set parallel to the ground or inclined relative to the ground. Of course, in some other feasible embodiments, the preset attitude of the vehicle 100 is determined according to the actual working conditions, and no specific limitation is made in this embodiment.

[0047] In order to accurately obtain the current attitude information of the vehicle 100, the attitude detector is preferably an electronic level. The electronic level is set on the vehicle 100 and is electrically connected to the controller. It can be understood that when the frame of the vehicle 100 is overall rigid, there is one electronic level. After the vehicle 100 is parked at any position, the current attitude information of the vehicle 100 is detected by this attitude detector, and the detected value is fed back to the controller. Subsequently, the controller adjusts the attitude of the vehicle 100. In addition, the set electronic level is electrically connected to the controller, which is convenient for the controller to monitor the attitude information of the vehicle 100 in real time.

[0048] In some other feasible embodiments, the posture detection component may also select other existing detection elements, and after obtaining the current posture information of the vehicle 100, the posture detection component may also manually feed back the current posture information to the controller, which is not specifically limited in this embodiment.

[0049] In addition, when the frame of the vehicle 100 is not rigid as a whole, one posture detection member is not enough to detect the horizontality of various parts of the vehicle 100. Therefore, multiple posture detection members are provided, and the multiple posture detection members are electrically connected to the controller. The multiple stroke detection members 2 are respectively configured to detect the extension stroke of the support end 13 of each support member 1. In addition, the multiple posture detection members are preferably provided in a one-to-one correspondence with the multiple support members 1. It can be understood that after the multiple posture detection members detect the current posture information of the corresponding positions of the vehicle 100, the current posture information of each position is transmitted to the controller respectively, and then the controller controls the support ends 13 of the multiple support members 1 to extend the specified stroke respectively. And the corresponding arrangement of the posture detection members and the support members 1 can further adjust the posture of each position of the vehicle 100.

[0050] In this embodiment, any support member 1 includes a hydraulic cylinder 11 and a hydraulic control mechanism, the hydraulic cylinder 11 is arranged at the bottom of the frame of the vehicle 100, the support end 13 is arranged at the end of the piston rod of the hydraulic cylinder 11, and the piston rod of the hydraulic cylinder 11 can extend toward the platform to cooperate in lifting the vehicle 100. The hydraulic control mechanism is electrically connected to the controller and is configured to adjust the change in the stroke of the support end 13. It can be understood that when adjusting the posture of the vehicle 100, the controller determines the change in the stroke of each support end 13 based on the current posture information of each position of the vehicle 100, so that the oil supply of each hydraulic control mechanism can be completed at one time, so that each hydraulic cylinder 11 can control the change in the stroke of the support end 13 through its corresponding hydraulic control mechanism.

[0051] In some other feasible embodiments, the hydraulic cylinder 11 may also be replaced by a linear drive mechanism such as a pneumatic cylinder or an electric push rod, which is not specifically limited in this embodiment.

[0052] In addition, in order to make the support member 1 suitable for platforms in various conditions, such as soft, muddy, etc., the support end 13 is a disc-shaped structure, and the diameter of the support end 13 is larger than the diameter of the piston rod of the hydraulic cylinder 11 to improve the stability of the support member 1 when supporting the vehicle 100.

[0053] Furthermore, the support member 1 further includes a mounting block 12 for fixing the hydraulic cylinder 11, and the mounting block 12 can be set on the vehicle frame with adjustable height. It can be understood that the mounting block 12 can be detachably set on the vehicle frame and can be adjusted to different heights according to needs to compensate for the extension distance of the piston rod, so as to largely avoid the phenomenon that the vehicle frame cannot be in a horizontal state even when the piston rod is at the maximum stroke.

[0054] Specifically, a plurality of first mounting portions 121 are uniformly arranged on the mounting block 12 along the length direction of the hydraulic cylinder 11, and a plurality of second mounting portions are uniformly arranged on the vehicle frame along the length direction of the hydraulic cylinder 11. Any one of the first mounting portions 121 and any one of the second mounting portions can be connected through a connecting member. It can be understood that when installing the mounting block 12, any one of the first mounting portions 121 is correspondingly arranged with any one of the second mounting portions, and then the corresponding first mounting portion 121 and the second mounting portion are connected through the connecting member. When it is necessary to adjust the height of the mounting block 12, other first mounting portions 121 and / or other second mounting portions with appropriate heights are selected and connected again through the mounting block 12.

[0055] Exemplarily, the first mounting portion 121 and the second mounting portion are a first mounting hole and a second mounting hole respectively opened on the mounting block 12 and the vehicle frame, and the connecting member is a bolt adapted to the first mounting hole and the second mounting hole. In some other feasible embodiments, the connection manner between the first mounting portion 121 and the second mounting portion can also be other connection structures, which are not specifically limited in this embodiment.

[0056] Preferably, any stroke detection member 2 is a wire rope displacement encoder, and the wire rope displacement encoder is arranged on the hydraulic cylinder 11, and the end of the wire 3 of the wire rope displacement encoder is connected to the end of the piston rod of the hydraulic cylinder 11 to keep the wire 3 parallel to the piston rod of the hydraulic cylinder 11. Keeping the wire 3 parallel to the piston rod is convenient for improving the accuracy of the wire rope displacement encoder to detect the change amount of the length of the hydraulic cylinder 11.

[0057] In some other feasible embodiments, the stroke detection member 2 can also be a displacement sensor or other existing displacement encoders, which are not specifically limited in this embodiment.

[0058] In this embodiment, a vehicle attitude adjustment method is also proposed, which is used to adjust the vehicle 100 parked on the platform to a preset attitude. The vehicle attitude adjustment method includes:

[0059] The current posture information of the vehicle 100 is obtained, so that a plurality of support members 1 arranged at different parts of the vehicle 100 and having support ends 13 that can be extended and supported on the platform cooperate to lift the vehicle 100. Subsequently, based on the comparison between the obtained current posture information and the preset posture information, the designated stroke that each support end 13 should extend is determined. Finally, each support end 13 is controlled to adjust the extension stroke until the corresponding measured extension stroke of each support end 13 matches the designated stroke.

[0060] The current posture information is obtained by using an electronic level meter installed on the vehicle 100. When the frame of the vehicle 100 is rigid as a whole, one electronic level meter is installed. When the frame of the vehicle 100 is not rigid as a whole, multiple electronic level meters are installed, and multiple electronic level meters are installed at various parts of the vehicle 100. After the electronic level meter obtains the current posture information of the vehicle 100, it can feed back the current posture information to the controller, and the controller starts to control the support member 1 to adjust the posture of the vehicle 100.

[0061] It is worth noting that the specified travel of each support end 13 is selected to make the wheels of the vehicle 100 leave the platform. It is understandable that after the posture of the vehicle 100 is adjusted to the preset posture, all wheels of the vehicle 100 are in a suspended state.

[0062] In addition, it is determined whether the current stroke of each support end 13 is consistent with the specified stroke. If not, the support end 13 with the stroke deviation is corrected to the specified stroke. It is understandable that the stroke of the support end 13 can be detected in real time by the stroke detection member 2. If the stroke of the support end 13 does not match the specified stroke calculated by the controller, the controller will recalibrate the stroke of the support end 13 to keep the vehicle 100 in a preset posture. The situation where the stroke of the support end 13 does not match the specified stroke calculated by the controller includes but is not limited to that when the vehicle 100 is parked for a long time, due to the weight of the vehicle 100 itself plus its load, each hydraulic cylinder 11 may retract to varying degrees.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
