Description

Technical Field

[0001] The present invention relates to the field of automobiles, in particular to a lifting and lying driving electric vehicle device. Background Art

[0002] Currently, family sedans and sports cars differ in height, and this difference in height results in the following advantages and disadvantages in actual driving: First, sports cars typically have a lower height than family sedans, offering advantages such as reduced drag coefficient, lower fuel consumption, a lower center of gravity, and improved driving stability. However, they also have disadvantages such as limited interior space, inconvenient ingress and egress, and a sense of oppression. Second, family sedans typically have a height between 1400 and 1600 mm, higher than sports cars. This offers advantages such as greater interior space for passengers and movement, easier ingress and egress, and a less oppressive feeling. However, it also has disadvantages such as a higher drag coefficient, higher fuel consumption, and a higher center of gravity that affects high-speed stability. Therefore, existing family sedans and sports cars, due to their fixed and unadjustable heights, have opposing advantages and disadvantages. Therefore, the applicant believes that it is very necessary to design a lifting and lying driving electric vehicle device with a small drag coefficient, low power consumption, low center of gravity, high driving stability, sufficient space for activities in the vehicle during rest, convenient getting on and off, and low sense of oppression. Summary of the Invention

[0003] The object of the present invention is to solve the above-mentioned problems and shortcomings, and to provide a lifting and lying driving electric vehicle device. The lifting and lying driving electric vehicle device has the advantages of small wind resistance coefficient, low power consumption, low center of gravity, high driving stability during driving, sufficient space for activities in the vehicle during rest, convenient getting on and off the vehicle, and low sense of oppression. It travels in a low vehicle body height state, so that the overall structural strength of the vehicle body is also guaranteed, and the rear-lying driving state makes driving and riding more comfortable. At the same time, the glass plate can play a sealing role when the vehicle body height is raised or lowered to ensure the safety of people in the vehicle and anti-theft performance, and rainwater is not easy to flow into the vehicle.

[0004] The technical solution of the present invention is achieved as follows: a lifting and lying driving electric vehicle device includes a vehicle chassis system, a drive motor, wheels, and a battery pack, which is characterized in that it includes a lower body enclosed and arranged on the four sides of the vehicle chassis system, doors are respectively provided on both sides of the lower body, and a low lying seat for the driver and passengers is provided in the lower body; an upper body is arranged above the lower body and is assembled and connected to the lower body in an integral manner, the upper body is composed of a roof, a windshield, and a hood that are made into an integral structure with each other, and an electric lifting mechanism for driving the upper body to perform an overall lifting or lowering action is also provided between the upper body and the lower body; a glass plate with a lifting structure is provided in the door, and the glass plate can be lifted to be in contact with the edge of the upper body when the upper body is in a raised state or a lowered state.

[0024] like Figure 1 、 Figure 6 and Figure 7 As shown, the present invention relates to a lifting and lying electric vehicle device, comprising a vehicle chassis system 1, a drive motor 2, wheels 3, and a battery pack 10. To achieve the purpose of the present invention, the present invention further comprises a lower body 4 enclosed on all sides of the vehicle chassis system 1, doors 5 being provided on both sides of the lower body 4, and a low-lying seat 6 for the driver and passengers being provided inside the lower body 4; a lower body 4 being provided above the lower body 4 and being nested and assembled with the lower body 4. The upper half of the vehicle body 7 is formed in an integral manner, and the upper half of the vehicle body 7 is composed of a roof 71, a windshield 72, and a hood 73 that are made into an integral structure. An electric lifting mechanism 8 for driving the upper half of the vehicle body 7 to rise or fall as a whole is also provided between the upper half of the vehicle body 7 and the lower half of the vehicle body 4; a glass plate 9 of a lifting structure is provided in the door 5, and the glass plate 9 can be raised to engage with the edge of the upper half of the vehicle body 7 when the upper half of the vehicle body 7 is in the raised state or the lowered state.

[0025] In practical applications, such as Figure 1 and Figure 2As shown, the height of the door 5 is higher than that of the lower body 4. This allows the door 5 to accommodate a taller glass panel 9, allowing the glass panel 9 to rise to engage the edge of the upper body 7 whether the upper body 7 is raised or lowered. A glass panel lifting mechanism is provided within the door 5 to drive the glass panel 9 upward and downward. This glass panel lifting mechanism is conventional in existing automotive doors. The specific structure and operating principles can be found in Chinese Patent Application No. 201510797491.1, entitled "Window Lifter," and will not be elaborated upon here.

[0026] In order to make the charging of electric vehicles more energy-saving and environmentally friendly, and to make charging more convenient without having to go to special public charging facilities for charging, such as Figure 1 and Figure 6 As shown, the roof 71 or hood 73 is also provided with a solar panel 20, which is electrically connected to the battery pack 10. This allows the battery pack 10 to be charged in the presence of sunlight, whether the vehicle is driving or stopped, thereby continuously extending driving time and providing greater convenience. In practical applications, the solar panel 20 can be provided on either the roof 71 or the hood 73. Preferably, the present invention provides solar panels 20 on both the roof 71 and the hood 73, which provides a larger sunlight receiving area, generates a larger current, and improves power generation efficiency.

[0027] In order to make the receiving surface of the solar cell panel 20 face the sun better, so as to achieve better sunlight receiving performance, generate greater current and improve power generation efficiency, such as Figure 3 As shown, one side of the solar panel 20 is hinged to one side of the roof 71 or the hood 73, and a telescopic support rod 30 is provided between the other side of the solar panel 20 and the other side of the roof 71 or the hood 73. In actual use, the telescopic support rod 30 is a hydraulic cylinder or a screw-type electric telescopic push rod, etc., which eliminates the need to manually lift the solar panel 20, making it more convenient to use.

[0028] In order to further increase the sunlight receiving area and improve the power generation efficiency, so as to further generate a larger current and charge faster, such as Figure 3 and Figure 4 As shown, the bottom surface of the solar panel 20 is also provided with a second solar panel 40 that can be pulled out and deployed from the bottom of the solar panel 20. In this way, the second solar panel 40 can be pulled out for use when the vehicle is parked for charging, and can be retracted when the vehicle is driving to prevent driving from being affected.

[0029] In order to make the pulling and retracting movement of the second solar cell panel 40 more stable and smooth, and without the need for manual pulling and pushing, it is more convenient to use. Figure 3 As shown, a sliding guide rail 401 and an electric push rod assembly 402 are further provided between the second solar cell panel 40 and the solar cell panel 20. By providing the sliding guide rail 401, the pulling and retracting motion can be made more stable and smooth. Figure 3 As shown, there are two sliding rails 401, and the second solar panel 40 is slidably disposed between the two sliding rails 401. A support connection portion 4011 is further provided between the two sliding rails 401, and the second solar panel 40 is further positioned between the support connection portion 4011 and the solar panel 20. One end of the telescopic support rod 30 is hinged to the support connection portion 4011, and the other end of the telescopic support rod 30 is hinged to the roof 71 or the hood 73. The provision of the support connection portion 4011 facilitates connection with the telescopic support rod 30 without affecting the sliding of the second solar panel 40.

[0030] In practical applications, the electric push rod assembly 402 can be a hydraulic cylinder or a screw-type electric telescopic push rod. Preferably, in order to make the electric pulling and electric retraction of the second solar panel 40 longer, so that the second solar panel 40 with a larger area can be hidden on the bottom surface of the solar panel 20, the electric push rod assembly 402 of the present invention adopts the following technical solutions, such as Figure 10 As shown, the electric push rod assembly 402 includes a drive motor 403, a screw 404, a slider 405, and two mounting brackets 406. The drive motor 403 and the two mounting brackets 406 are respectively disposed on the bottom surface of the solar panel 20. The two ends of the screw 404 are rotatably inserted into the two mounting brackets 406, and one end of the screw 404 is fixedly connected to the power output end of the drive motor 403 so that the drive motor 403 can drive the screw 404 to rotate. The axial direction of the screw 404 is the same as the extension and retraction direction of the second solar panel 40. The slider 405 is fixed to the second solar panel 40 and is threadedly connected to the screw 404. During use, the second solar panel 40 can be extended or retracted by driving the screw 404 in the forward or reverse direction.

[0031] In practical applications, such as Figure 3 and Figure 5As shown, a removable cover box 74 is nested and mounted on the top surfaces of the roof 71 and hood 73, covering the top surfaces thereof. The top surface of the cover box 74 also defines an upwardly opening receiving cavity 741. The solar panel 20 is mounted on the opening of the receiving cavity 741, and the second solar panel 40, the sliding guide rail 401, the electric push rod assembly 402, and the telescopic support rod 30 are all movable within the receiving cavity 741. The cover box 74 prevents the roof 71 and hood 73 from being exposed when the solar panel 20 is opened, thereby preventing people and items inside the vehicle from being exposed. Furthermore, the removable design of the cover box 74 facilitates removal and cleaning of the receiving cavity 741 if leaves, dust, or garbage accumulate. Specifically, the other end of the telescopic support rod 30 is hingedly connected to the cover box 74.

[0032] In practical applications, the electric lifting mechanism 8 can adopt the commonly used electric telescopic push rod on the market. As a preference, in order to make the lifting action of the upper part of the vehicle body 7 more stable, with better load-bearing performance and safer and more reliable to use, the electric lifting mechanism 8 of the present invention adopts the following technical solutions, such as Figure 9 As shown, the electric lifting mechanism 8 is composed of a guide rail top rod 81, a first oblique support rod 82, a second oblique support rod 83, a guide rail bottom rod 84, and an electric push rod 85. One end of the first oblique support rod 82 is hingedly connected to one end of the guide rail bottom rod 84, and the other end of the first oblique support rod 82 is hingedly connected to a first slider 86 nested on the guide rail top rod 81; one end of the second oblique support rod 83 is hingedly connected to one end of the guide rail top rod 81, and the other end of the second oblique support rod 83 is hingedly connected to a second slider 87 nested on the guide rail bottom rod 84; one end of the electric push rod 85 is hingedly connected to the first oblique support rod 82, and the other end of the electric push rod 85 is hingedly connected to the second oblique support rod 83. Through this structural design, an X-shaped electric lifting mechanism with four connection support points can be formed, which is not easy to break during use, has better load-bearing performance, and more stable lifting action. The electric push rod 85 is a hydraulic cylinder or a screw-type electric telescopic push rod, etc. The X-shaped electric lifting mechanism can also be replaced by a hydraulic cylinder or a screw-type electric telescopic push rod.

[0033] In order to hide the electric lifting mechanism 8 in the car without exposing it to the outside, and to make the lifting action of the electric lifting mechanism 8 less susceptible to obstruction by external objects, and to make it more reliable to use, Figure 7 and Figure 9 As shown, the guide rail top rod 81 is fixedly connected to the inner side of the upper half of the vehicle body 7 , and the guide rail bottom rod 84 is fixedly connected to the inner side of the lower half of the vehicle body 4 .

[0034] In order to further increase the lifting adjustment distance and improve the adjustment range, the vehicle body height can be lowered when lowering and higher when raising, such as Figure 8 As shown, a middle car body 100 is nested between the lower car body 4 and the upper car body 7. The middle car body 100 is surrounded by side panels. The upper half of the middle car body 100 is nested with the upper car body 7, and the lower half of the middle car body 100 is nested with the lower car body 4. In actual use, to prevent the middle car body 100 from detaching from the lower car body 4 and the upper car body 7, a first anti-detachment hook 102 is provided between the middle car body 100 and the lower car body 4, and a second anti-detachment hook 103 is provided between the middle car body 100 and the upper car body 7. The provision of the first anti-detachment hook 102 and the second anti-detachment hook 103 allows the middle car body 100 to be lifted when the upper car body 7 is lifted. In order to make the upper part of the vehicle body 7 move downwards, the middle part of the vehicle body 100 can be driven downwards. Figure 8 As shown, the bottom of the middle vehicle body 100 is further provided with a linkage protrusion 104 that can contact the bottom of the upper vehicle body 7 .

[0035] In order to further improve the sealing performance and prevent rainwater from leaking into the car, such as Figure 8 As shown, a sealing strip 101 is provided between the lower half of the vehicle body 4 and the middle vehicle body 100, and a sealing strip 101 is provided between the upper half of the vehicle body 7 and the middle vehicle body 100; Figure 8 As shown, the sealing strip 101 is arranged on the first anti-detachment hook portion 102 or the second anti-detachment hook portion 103, so that the sealing strip 101 occupies less space.

[0036] In practical applications, in order to improve the driving safety of vehicles, such as Figure 1 and Figure 4 As shown, the front end of the lower half of the vehicle body 4 is provided with a lighting lamp 41, a turn signal lamp 42, and a camera or detection probe 43, while the rear end of the lower half of the vehicle body 4 is provided with a turn signal lamp 42, a brake light 44, and a camera or detection probe 43. The solution of the present invention can also be implemented with various radar components and laser components, combined with computing power and software, to achieve unmanned driving.

[0037] In order to facilitate the use of public charging facilities to charge the battery pack 10 in emergency power needs, a charging port 45 electrically connected to the battery pack 10 is further provided on the lower half of the vehicle body 4.

[0038] In actual application, the vehicle chassis system 1 includes components used in the automobile, such as a clutch, a transmission, a universal joint, a suspension system, a brake device, a steering wheel and a steering column, a steering gear, and a steering rod. Its specific structure and operating principle are existing conventional well-known technologies and will not be elaborated here.

[0039] When getting on and off the vehicle, in order to free up more space for leg movement and make getting on and off the vehicle more convenient, the steering wheel provided on the vehicle chassis system 1 adopts a steering wheel structure that can be flipped and folded upward. Its specific structure and usage principle can be referred to the Chinese patent document with patent application number 202310335055.7 and the name "A folding steering wheel and a car", which will not be elaborated here.

[0040] When implementing the solution of the present invention, it is also possible to respectively add an intelligent control IC chip and a circuit board to the electric lifting mechanism 8, the telescopic support rod 30, and the electric push rod assembly 402, and then control the operation of the electric lifting mechanism 8, the telescopic support rod 30, and the electric push rod assembly 402 through the intelligent control IC chip and the circuit board. At the same time, a wireless communication module such as a Bluetooth communication module and a WIFI module for transmitting control signals to and from the intelligent control IC chip and the circuit board can also be added, and corresponding control APP software can be developed to enable a smartphone, tablet computer, or the like to control the operation of the electric lifting mechanism 8, the telescopic support rod 30, and the electric push rod assembly 402.
