Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically to vehicle body structure and vehicles. Background Technology

[0002] With the advancement of vehicle technology, drones are being installed in vehicles to further enhance the driving experience. Drones can provide passengers with a bird's-eye view, whether the vehicle is stationary or in motion, offering a unique sightseeing experience. Furthermore, in extreme road conditions, drones can help passengers scout out the road, thereby improving vehicle safety when driving in such conditions.

[0003] In existing technologies, the vehicle body structure includes a drone take-off and landing device, which is retractably installed in the vehicle's trunk to carry the drone. However, this drone take-off and landing device occupies a significant amount of space in the vehicle's trunk, resulting in a poor spatial layout of the vehicle body structure. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a vehicle body structure and vehicle that aims to solve the problem of how to deploy unmanned aerial vehicle take-off and landing devices to optimize the spatial layout of the vehicle body structure.

[0005] In a first aspect, embodiments of this application provide a vehicle body structure, including a trunk chassis, a support device, and a drone, wherein the support device is connected to the bottom of the trunk chassis, and the drone is mounted on the support device.

[0006] Based on the aforementioned technical means, by placing the carrier device, i.e., the device suitable for drone take-off and landing, at the bottom of the vehicle's trunk chassis, the carrier device does not occupy the vehicle's trunk space or passenger space, and does not reduce the vehicle's cargo space or passenger space. Furthermore, whether the vehicle is stationary or in motion, there is no need to change the vehicle's shape to enable drone take-off and landing on the carrier device (when the carrier device is located in the trunk, the trunk or rear windshield needs to be opened for drone take-off and landing). This improves the safety of drone take-off and landing operations while the vehicle is in motion. In summary, by placing the carrier device at the bottom of the trunk chassis, the spatial layout of the vehicle body structure is optimized, providing a more rational, safe, and reliable vehicle body structure.

[0007] In some embodiments, the vehicle body structure further includes a rear bumper beam, which is connected to the rear end of the trunk chassis along the length of the vehicle body structure and forms an accommodating space with the trunk chassis.

[0008] The support device can switch between a retracted state and an extended state. When the support device is in the retracted state, both the support device and the drone are located within the accommodating space. When the support device is in the extended state, a portion of the support device and the drone are located under the rear anti-collision beam.

[0009] Based on the aforementioned technical means, a storage space is formed by the rear bumper beam and the trunk chassis. This allows both the carrier and the drone to be housed within this space when the carrier is in its retracted state, facilitating their placement on the vehicle's structure. Simultaneously, in the retracted state, the rear bumper beam provides protection for both the carrier and the drone, preventing damage.

[0010] Furthermore, when the support device is in the extended state, the drone, positioned under the rear bumper beam, can be lifted from the storage space to the outside, facilitating takeoff and landing and preventing it from being affected by the rear bumper beam. Additionally, because the drone is positioned under the rear bumper beam in the extended state, the rear bumper beam and the vehicle's structural components, such as the trunk above it, can partially block airflow when the drone takes off and lands while the vehicle is in motion. This helps improve the stability and reliability of takeoff and landing on the support device.

[0011] In some embodiments, a portion of the carrier and the drone are located on the rear side of the rear bumper beam in the longitudinal direction.

[0012] Based on the aforementioned technical means, the rear bumper beam has a smaller impact on the drone during takeoff and landing, thus facilitating takeoff and landing. Furthermore, when the vehicle is in motion, the rear bumper beam can better block airflow for the drone during takeoff and landing, thereby improving the stability and reliability of the drone's takeoff and landing on the carrier.

[0013] In some embodiments, the carrying device includes a drive component, a transmission component, and a carrying platform. The drone is mounted on the carrying platform, and the transmission component is tractively connected between the drive component and the carrying platform. The drive component can drive the carrying platform to move through the transmission component, so that the carrying device switches between the retracted state and the extended state.

[0014] Based on the aforementioned technical means, when the drone needs to take off or land, the drive component can drive the transmission component to move the carrier platform, moving it from the accommodating space to the underside or rear side of the rear bumper beam. This allows the carrier device to switch from a retracted state to an extended state, facilitating drone takeoff or landing. After the drone lands, the drive component can drive the transmission component to move the carrier platform and the drone back into the accommodating space, switching the carrier device from an extended state to a retracted state for drone storage. This method of switching the carrier device between retracted and extended states only requires controlling the drive component, making the state switching convenient and the functional division of each part of the carrier device clear, thus facilitating its manufacturing.

[0015] In some embodiments, the transmission assembly includes a support member, a driving member, a linkage member, and a pushing member, and the drive assembly is connected to the support member. The output shaft of the drive assembly is connected to one end of the driving member to drive the driving member to rotate. The other end of the driving member is rotatably connected to one end of the pushing member, and the other end of the pushing member is connected to the support platform. One end of the linkage member is rotatably connected to the support member, and the other end of the linkage member is rotatably connected to the pushing member.

[0016] Based on the aforementioned technical means, the cooperation of the support component, driving component, linkage component, and propulsion component allows the carrying device to accurately switch between extended and retracted states, facilitating the takeoff, landing, and storage of the drone. Furthermore, the support component, driving component, linkage component, and propulsion component can form a four-bar linkage structure. This structure simplifies the transmission components, improves their reliability, and enhances the stability and reliability of the carrying device when switching between extended and retracted states.

[0017] In some embodiments, the transmission assembly includes a first transmission member, a second transmission member, a first power member, and a second power member. The output shaft of the drive assembly is connected to one end of the first transmission member to drive the first transmission member to rotate. The first power member is connected to the other end of the first transmission member and to one end of the second transmission member to drive the second transmission member to rotate. The second power member is connected to the other end of the second transmission member and to the support platform to drive the support platform to rotate.

[0018] Based on the aforementioned technical means, through the cooperation of the drive components, the first transmission component, the second transmission component, the first power component, and the second power component, the position of the support platform can be adjusted more flexibly when switching between the retracted and extended states of the support device, thereby minimizing interference between the support platform and components such as the rear anti-collision beam. Furthermore, this design allows for more flexible movement of the transmission components, contributing to improved performance of the support device and enhancing the safety and reliability of the UAV during takeoff and landing on the support platform.

[0019] In some embodiments, the drive assembly includes a third power component, a first drive shaft, and a second drive shaft. The axial direction of the first drive shaft is aligned with the length direction of the vehicle body structure. The output shaft of the third power component is drively connected to one end of the first drive shaft to drive the first drive shaft to rotate. The other end of the first drive shaft is drively connected to the second drive shaft to drive the second drive shaft to rotate. The axial direction of the second drive shaft is aligned with the width direction of the vehicle body structure, and the second drive shaft is drively connected to the transmission assembly. The axial direction of the output shaft of the third power component is parallel to the axial direction of the second drive shaft, and the second drive shaft forms the output shaft of the drive assembly.

[0020] According to the above technical means, the power of the third power component can be transmitted from the first drive shaft to the second drive shaft, then from the second drive shaft to the transmission assembly, and finally from the transmission assembly to the support platform to drive the support platform to move, thereby realizing the switching of the support device between the retracted state and the extended state.

[0021] Since the structure of the trunk chassis is relatively complex and may include other components, in the above configuration, by setting the axial direction of the first drive shaft to be consistent with the length direction of the vehicle body structure, connecting the output shaft of the third power unit to one end of the first drive shaft, and connecting the second drive shaft to the other end of the first drive shaft, the third power unit and the second drive shaft can be arranged along the axial direction of the first drive shaft (i.e., the length direction of the vehicle body structure).

[0022] Furthermore, the axial direction of the second drive shaft is aligned with the width direction of the vehicle body structure. The second drive shaft is connected to the transmission assembly, allowing the third power component and the transmission assembly to be arranged along the length direction of the vehicle body structure and staggered in the width direction. This provides ample space between the third power component and the transmission assembly, with only the first and second drive shafts residing within this space. This allows other components to be placed where the first and second drive shafts are located, avoiding interference between these components and the third power component and transmission assembly. This facilitates the spatial arrangement of the drive assembly and transmission assembly and meets the requirement of transmitting power from the third power component to the transmission assembly.

[0023] In some embodiments, the drive assembly further includes a first engaging member and a second engaging member, the first drive shaft includes a first engaging portion and a second engaging portion, the first engaging member is disposed on the output shaft of the third power member and engages with the first engaging portion, and the second engaging member is disposed on the second drive shaft and engages with the second engaging portion.

[0024] According to the aforementioned technical means, by having a first meshing member on the output shaft of the third power component mesh with a first meshing part of the first transmission shaft, and a second meshing member on the second transmission shaft mesh with a second meshing part of the first transmission shaft, the transmission connection between the third power component and the first transmission shaft, as well as between the first and second transmission shafts, can be facilitated, enabling the third power component to smoothly transmit power to the transmission assembly. Furthermore, this meshing connection method provides accurate transmission and reliable performance, thereby improving the working performance of the drive assembly.

[0025] In some embodiments, the vehicle body structure further includes a lifting assembly connected to the trunk chassis and the load-bearing device, for driving the load-bearing device to move along the height direction of the vehicle body structure.

[0026] Based on the aforementioned technical means, by setting up a lifting component to drive the carrier device to move along the height direction of the vehicle body structure, the carrier device can switch from an extended state to a retracted state when the drone is not in use. Then, the lifting component can raise the carrier device, along with the drone, along the height direction of the vehicle body structure to a position close to the trunk chassis, thereby increasing the height of the carrier device and the drone above the ground within the storage space. This increases the height of the carrier device above the ground in the retracted state, preventing collisions between the carrier device and the drone and obstacles on the road surface during vehicle movement, thus avoiding damage to the carrier device and the drone.

[0027] When a drone is needed, the carrier device, along with the drone, is moved a certain distance down along the height of the vehicle body structure. The carrier device then moves the drone to the underside or rear side of the rear bumper beam, making it easier for the carrier device to switch from a retracted state to an extended state, allowing the drone to take off or land.

[0028] In some embodiments, the support platform includes a main structure and a first conductive element connected to the main structure; the drone includes a body and a second conductive element connected to the bottom of the body. The first conductive element and the second conductive element are electrically connected to charge the drone.

[0029] Based on the aforementioned technical means, by setting a first conductive component on the support platform and a second conductive component on the drone, when the support device is in its retracted state and the drone is located on the support platform, the first and second conductive components can be electrically connected to charge the drone through the support device. This enhances the functionality of the support device and facilitates the use of the drone.

[0030] In some embodiments, the support platform further includes a plurality of protrusions disposed on the main structure, the plurality of protrusions being spaced apart, and any two adjacent protrusions and the main structure forming a water guide channel. Each protrusion is provided with the first conductive element.

[0031] According to the above technical means, by setting multiple protrusions on the support platform to form a water channel with the main structure, the water accumulated on the support platform can be easily drained away from the support platform, keeping the support platform clean and dry, and preventing short circuits when charging the drone through the support platform.

[0032] In some embodiments, along the arrangement direction of the plurality of protrusions, the maximum size of the second conductive element is greater than the maximum size of the water channel.

[0033] Based on the above technical means, this can avoid the situation where the second conductive component is located in the water channel when the drone is on the carrier platform, that is, the second conductive component is not in contact with the first conductive component, thus making it impossible to charge the drone, thereby improving the reliability of the carrier platform's charging function.

[0034] In some embodiments, along the arrangement direction of the plurality of protrusions, the maximum size of the second conductive element is greater than the maximum size of the first conductive element.

[0035] Based on the above technical means, it can be understood that this ensures the reliability of the electrical connection between the second conductive component and the first conductive component after the drone lands on the support platform, thereby further improving the reliability of the support platform's charging function.

[0036] Secondly, embodiments of this application provide a vehicle including any of the aforementioned body structures. Attached Figure Description

Detailed Implementation

[0040] The terms “first,” “second,” etc., are used for descriptive purposes only and have no sequential or technical meaning, nor should they be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0041] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. "Rotary connection" refers to a connection where the two parts can rotate relative to each other after connection. "Sliding connection" refers to a connection where the two parts can slide relative to each other after connection.

[0042] The terms "parallel" and "perpendicular" are relative to the current technological level, not absolute mathematical definitions. Slight deviations are permissible; approximations of parallelism or perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, with the angle between them ranging from 0 to 5 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, with the angle between them ranging from 85 to 95 degrees.

[0043] The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] See Figure 1 Some embodiments of this application provide a vehicle 01. For example, vehicle 01 can be a fuel vehicle, a pure electric vehicle, a hybrid electric vehicle, etc., and this application does not specifically limit it.

[0045] In some embodiments, vehicle 01 includes a body structure 100 and wheels 200. The body structure 100 has a passenger space V1 for occupants to drive or ride in vehicle 01, and the wheels 200 are connected to the body structure 100 and are adapted to contact the road surface so that the vehicle 01 can be driven by the rotation of the wheels 200.

[0046] In some embodiments, the vehicle body structure 100 also includes a trunk 20, which is located on the side of the passenger space V1 near the rear of the vehicle along the length of the vehicle body structure 100. The trunk 20 can be used to store personal belongings of the occupants, vehicle toolboxes, or other items or goods.

[0047] Currently, to further enhance the driving experience for passengers, a drone 30 is often installed on vehicle 01. However, in related technologies, installing a drone 30 take-off and landing device on the vehicle body structure 100 results in a poor spatial layout of the vehicle body structure 100. Therefore, this application provides a vehicle body structure 100 that optimizes its spatial layout.

[0048] See Figures 1 to 7 The vehicle body structure 100 provided in this application includes a trunk 20 chassis, a support device 10, and a drone 30. The trunk 20 chassis is located on the lower side of the trunk 20 and is used to support the trunk 20. The support device 10 is connected to the bottom of the trunk 20 chassis, and the drone 30 is mounted on the support device 10.

[0049] By placing the support device 10, i.e., the device suitable for the take-off and landing of the drone 30, at the bottom of the trunk 20 chassis of the vehicle 01, the support device 10 does not occupy the space of the trunk 20 or the passenger space V1 of the vehicle 01, and does not reduce the cargo space or passenger space V1 of the vehicle 01. Furthermore, whether the vehicle 01 is stationary or in motion, it is not necessary to change the shape of the vehicle 01 to enable the drone 30 to take off and land on the support device 10 (when the support device is placed inside the trunk, the trunk or rear windshield needs to be opened to enable the drone to take off and land). This improves the safety of performing drone take-off and landing operations while the vehicle 01 is in motion. In summary, by placing the support device 10 at the bottom of the trunk 20 chassis, the spatial layout of the vehicle body structure 100 is optimized, providing a more reasonable, safe, and reliable vehicle body structure 100.

[0050] In some embodiments, the vehicle body structure 100 further includes a rear bumper beam, which is connected to the rear end of the trunk 20 chassis along the length of the vehicle body structure 100 and forms an accommodating space with the trunk 20 chassis. For example, the distance between the lower surface of the rear bumper beam and the ground is less than the distance between the lower surface of the trunk 20 chassis and the ground, such that the lower surface of the trunk 20 chassis and the surface of the rear bumper beam on the side of the trunk 20 chassis that defines the accommodating space.

[0051] The support device 10 can switch between a retracted state and an extended state. When the support device 10 is in the retracted state, both the support device 10 and the drone 30 are located within the accommodating space. When the support device 10 is in the extended state, part of the support device 10 and the drone 30 are located under the rear bumper beam.

[0052] The rear bumper beam and the chassis of the trunk 20 form a storage space, so that when the carrier 10 is in the stored state, both the carrier 10 and the drone 30 can be housed within the storage space, thus facilitating the deployment of the carrier 10 and the drone 30 on the vehicle body structure 100. At the same time, in the stored state, the rear bumper beam provides protection for the carrier 10 and the drone 30 to prevent damage.

[0053] Furthermore, when the support device 10 is in the extended state, the drone 30, located under the rear bumper beam, can be lifted from the accommodating space to the outside of the accommodating space, facilitating takeoff and landing of the drone 30 and preventing it from being affected by the rear bumper beam during takeoff and landing. In addition, since the drone 30 is located under the rear bumper beam in the extended state, when the vehicle 01 takes off and lands the drone 30, the rear bumper beam and the vehicle body structure 100 components such as the trunk 20 above the rear bumper beam can block some of the airflow for the drone 30, thus improving the stability and reliability of the drone 30 during takeoff and landing on the support device 10.

[0054] In other embodiments, when the carrier 10 is in the extended state, a portion of the carrier 10 and the drone 30 may be located behind the rear bumper beam along the length of the vehicle body structure 100. Thus, when the drone 30 needs to take off and land, the rear bumper beam has less impact on the drone 30, making takeoff and landing easier. Furthermore, when the drone 30 takes off and lands while the vehicle 01 is in motion, the rear bumper beam can better block airflow for the drone 30, thereby improving the stability and reliability of the drone 30's takeoff and landing on the carrier 10.

[0055] In some other embodiments, when the carrier 10 is in the extended state, a portion of the carrier 10 and the drone 30 may also be located on one side of the vehicle body structure 100 in its width direction. This also enables the drone 30 to take off and land while the vehicle 01 is in motion. At this time, a baffle can be set at a corresponding position on one side of the vehicle body structure 100 to shield the drone 30 from airflow and improve the stability of the drone 30 during takeoff and landing.

[0056] In some embodiments, see Figures 8 to 13 The support device 10 includes a drive assembly 1, a transmission assembly 2, and a support platform 3. The drone 30 is mounted on the support platform 3, meaning the drone 30 can land on the support platform 3. When the drone 30 is parked, the support platform 3 supports and secures the drone 30, and the drone 30 separates from the support platform 3 when taking off. For example, the drone 30 and the support platform 3 can be connected and separated magnetically. For instance, the bottom of the drone 30 is provided with a magnetic strip or magnetic block, and the support platform 3 is provided with an electromagnetic coil. When the support device 10 is in the retracted state and the drone 30 is located on the support platform 3, the electromagnetic coil can be energized to generate a magnetic force that attracts the magnetic strip on the drone 30, thus securing the drone 30 to the support platform 3. When the support device 10 is in the extended state and the drone 30 is about to take off from the support platform 3, the electromagnetic coil can be de-energized to allow the drone 30 to take off smoothly from the support platform 3.

[0057] In some examples, the support platform 3 can be a block structure, a strip structure, or a plate structure, etc.

[0058] The transmission component 2 is connected between the drive component 1 and the support platform 3. The drive component 1 can drive the support platform 3 to move through the transmission component 2, so that the support device 10 can switch between the retracted state and the extended state.

[0059] In this way, when the drone 30 needs to take off or land, the drive assembly 1 can drive the transmission assembly 2 to move the carrier platform 3, moving it from the accommodating space to the underside or rear side of the rear bumper beam. This allows the carrier device 10 to switch from a retracted state to an extended state, facilitating takeoff or landing of the drone 30. After the drone 30 lands, the drive assembly 1 can drive the transmission assembly 2 to move the carrier platform 3 and the drone 30 back into the accommodating space, switching the carrier device 10 from an extended state to a retracted state, thus accommodating the drone 30. This method of switching the carrier device 10 between the retracted and extended states only requires controlling the drive assembly 1, making the state switching of the carrier device 10 convenient. Furthermore, the functional division of each part of the carrier device 10 is clear, facilitating its manufacturing.

[0060] In some examples, the drive component 1 can be electrically connected to the controller of the vehicle 01, and the drive component 1 can be controlled by the controller to make it easier to control the take-off, landing and storage of the drone 30.

[0061] In some other embodiments, the support device may also consist only of a drive assembly and a support platform. For example, the drive assembly includes a hydraulic push rod, with the support platform connected to one end of the hydraulic push rod, and the drone mounted on the support platform. It is understood that by controlling the extension and retraction of the hydraulic push rod, the support device can be switched between a retracted state and an extended state.

[0062] In some embodiments, see Figure 13 The transmission assembly 2 includes a support member 21, a driving member 22, a linkage member 23, and a pushing member 24. The drive assembly 1 is connected to the support member 21. For example, both the drive assembly 1 and the support member 21 are connected to the bottom of the trunk 20 chassis to achieve the connection between the load-bearing device 10 and the trunk 20 chassis.

[0063] The output shaft of the drive assembly 1 is connected to one end of the drive member 22 to drive the drive member 22 to rotate. The other end of the drive member 22 is rotatably connected to one end of the push member 24. The other end of the push member 24 is connected to the support platform 3. One end of the linkage member 23 is rotatably connected to the support member 21. The other end of the linkage member 23 is rotatably connected to the push member 24.

[0064] The rotation axis of one end of the driving member 22 (the end connected to the output shaft of the drive assembly 1), the rotation axis of one end of the pushing member 24 (the end connected to the driving member 22), the rotation axis of one end of the linkage member 23 (the end connected to the support member 21), and the rotation axis of the other end of the linkage member 23 (the end connected to the pushing member 24) are all consistent with the width direction of the vehicle 01.

[0065] When the output shaft of drive assembly 1 rotates in the forward direction, since one end of the driving member 22 is connected to the output shaft of drive assembly 1, the output shaft can drive the driving member 22 to rotate around the axis of the output shaft. Since the other end of the driving member 22 is rotatably connected to one end of the pushing member 24, the other end of the driving member 22 (i.e., the end connected to the pushing member 24) can drive the pushing member 24 to swing axially around the output shaft. Furthermore, since one end of the linkage member 23 is rotatably connected to the support member 21, and the other end of the linkage member 23 is rotatably connected to the pushing member 24, when the pushing member 24 swings axially around the output shaft, under the restraining effect of the linkage member 23, the other end of the pushing member 24 (i.e., the end connected to the support member 24) can drive the pushing member 24 to swing axially around the output shaft. One end of the drive assembly 23 (connected to the support 21) can drive the linkage 23 to move. Simultaneously, one end of the linkage 23 (connected to the support 21) will rotate relative to the support 21, and the other end of the linkage 23 (connected to the pusher 24) will rotate relative to the pusher 24. One end of the pusher 24 (connected to the drive member 22) will also rotate relative to the drive member 22. This allows the linkage 23 to move the other end of the pusher 24 (connected to the support assembly 3) in a preset direction, and to drive the support assembly 3 in the preset direction, for example, moving the support body to the underside or rear side of the rear bumper beam, thus switching the support device 10 from a retracted state to an extended state. It is understood that when the output shaft of the drive assembly 1 rotates in the opposite direction, the support device 10 can switch from an extended state to a retracted state. The movement process of the drive member 22, linkage 23, and pusher 24 is the reverse of the movement process when the support device 10 switches from a retracted state to an extended state, and will not be described in detail here.

[0066] In this way, through the cooperation of the support member 21, the driving member 22, the linkage member 23, and the pusher member 24, the carrying device 10 can accurately switch between the extended state and the retracted state, facilitating the takeoff, landing, and retraction of the UAV 30. Furthermore, the support member 21, the driving member 22, the linkage member 23, and the pusher member 24 can form a four-bar linkage structure. This structure makes the transmission component 2 relatively simple in structure and reliable in performance, thereby improving the stability and reliability of the carrying device 10 in switching between the extended state and the retracted state.

[0067] In some examples, the support member 21, the driving member 22, the linkage member 23, and the pushing member 24 can be rod-shaped, column-shaped, or plate-shaped structures, etc.

[0068] In some examples, the drive assembly 1 and the support member 21 are connected to the trunk 20 chassis by welding. In other examples, the drive assembly 1 and the support member 21 are detachably connected to the trunk 20 chassis by fasteners such as bolts.

[0069] In some examples, the outer peripheral surface of the output shaft of the drive assembly 1 includes a limiting plane, the driving member 22 has a connecting hole, and the transmission assembly 2 also includes a limiting block disposed within the connecting hole and connected to the driving member 22. The output shaft of the drive assembly 1 passes through the connecting hole, and the limiting block contacts the limiting plane on the output shaft of the drive assembly 1, preventing the output shaft of the drive assembly 1 from rotating within the connecting hole, thereby achieving the connection between the output shaft of the drive assembly 1 and the driving member 22. In other examples, the output shaft of the drive assembly 1 can also be connected to the driving member 22 via a key connection.

[0070] In some examples, when the support device 10 is in the extended state, along the length of the vehicle body structure 100, the height of the end of the support platform 3 near the pusher 24 from the ground is higher than the height of the end of the support platform 3 away from the pusher 24 from the ground. Thus, when the drone 30 takes off or lands, the support platform 3 can also shield the drone 30 from some of the airflow, thereby improving the stability of the drone 30 during takeoff or landing.

[0071] In some other embodiments, see Figures 14 to 20 The transmission assembly includes a first transmission member 25, a second transmission member 26, a first power member 27, and a second power member 28. The output shaft of the drive assembly 1 is connected to one end of the first transmission member 25 to drive the first transmission member 25 to rotate. The first power member 27 is connected to the other end of the first transmission member 25 and to one end of the second transmission member 26 to drive the second transmission member 26 to rotate. The second power member 28 is connected to the other end of the second transmission member 26 and to the support platform 3 to drive the support platform 3 to rotate.

[0072] For example, the process of switching the support device 10 from the retracted state to the extended state is as follows: First, the first power member 27 rotates forward, causing the second transmission member 26 to move downward along the height direction of the vehicle body structure 100 near one end of the support platform 3. This moves the support platform 3 from the accommodating space to the outside of the accommodating space. Specifically, the downward movement of the support platform 3 is such that it does not interfere with components such as the rear bumper beam when it moves backward. Then, the output shaft of the drive assembly 1 rotates forward, driving the first transmission member 25 to rotate toward the rear bumper beam. This places the second transmission member 26 on the side of the first transmission member 25 near the rear of the vehicle along the length direction of the vehicle body structure 100. Afterward, the first power member 27 drives the second transmission member 26 to rotate upward again, causing the second transmission member 26 to move upward along the height direction of the vehicle body structure 100 near one end of the support platform 3. This moves the support platform 3 to the rear side of the rear bumper beam or to the lower side of the rear bumper beam without colliding with it, thereby switching the support device 10 to the extended state. The movement process of the drive assembly 1, the first transmission component 25, the second transmission component 26, the first power component 27 and the second power component 28 when the support device 10 switches from the extended state to the retracted state is the opposite of that when the support device 10 switches from the retracted state to the extended state, and will not be described in detail here.

[0073] Through the cooperation of the aforementioned drive assembly 1, first transmission component 25, second transmission component 26, first power component 27, and second power component 28, the position of the support platform 3 can be adjusted more flexibly when the support device 10 switches between the retracted and extended states, thereby minimizing interference between the support platform 3 and components such as the rear anti-collision beam. Furthermore, this design allows for more flexible movement of the transmission assembly 2, contributing to improved performance of the support device 10 and enhancing the safety and reliability of the UAV 30 during takeoff and landing on the support platform 3.

[0074] In some examples, the first transmission member 25 and the second transmission member 26 can be rod-shaped, plate-shaped, or strip-shaped structures.

[0075] In some examples, the first power component 27 and the second power component 28 can be an electric motor, etc.

[0076] In some embodiments, see Figure 11 The drive assembly 1 includes a third power component 11, a first drive shaft 12, and a second drive shaft 13. The axial direction of the first drive shaft 12 is consistent with the length direction of the vehicle body structure 100. The output shaft of the third power component 11 is connected to one end of the first drive shaft 12 for driving the first drive shaft 12 to rotate. The other end of the first drive shaft 12 is connected to the second drive shaft 13 for driving the second drive shaft 13 to rotate.

[0077] The axial direction of the second drive shaft 13 is consistent with the width direction of the vehicle body structure 100, and the second drive shaft 13 is connected to the transmission assembly 2. The axial direction of the output shaft of the third power component 11 is parallel to the axial direction of the second drive shaft 13, and the second drive shaft 13 forms the output shaft of the drive assembly 1.

[0078] In this way, the power of the third power component 11 can be transmitted from the first drive shaft 12 to the second drive shaft 13, then from the second drive shaft 13 to the transmission assembly 2, and finally from the transmission assembly 2 to the support platform 3, so as to drive the support platform 3 to move and realize the switching of the support device 10 between the retracted state and the extended state.

[0079] Since the structure of the trunk 20 chassis is relatively complex and may include other components, in the above configuration, by setting the axial direction of the first drive shaft 12 to be consistent with the length direction of the body structure 100, the output shaft of the third power component 11 is connected to one end of the first drive shaft 12, and the second drive shaft 13 is connected to the other end of the first drive shaft 12, the third power component 11 and the second drive shaft 13 can be arranged along the axial direction of the first drive shaft 12 (i.e., the length direction of the body structure 100).

[0080] Furthermore, the axial direction of the second drive shaft 13 is aligned with the width direction of the vehicle body structure 100. The second drive shaft 13 is connected to the transmission assembly 2, allowing the third power component 11 and the transmission assembly 2 to be arranged along the length direction of the vehicle body structure 100 and offset in the width direction. This allows for a larger space between the third power component 11 and the transmission assembly 2, with only the first drive shaft 12 and the second drive shaft 13 residing within this space. This allows other components to be placed where the first drive shaft 12 and the second drive shaft 13 are located, avoiding interference between other components and the third power component 11 and the transmission assembly 2. This facilitates the spatial arrangement of the drive assembly 1 and the transmission assembly 2 and meets the requirement of transmitting power from the third power component 11 to the transmission assembly 2.

[0081] In some examples, the third power component 11 may be an electric motor, a fuel engine, or a gas engine, etc. In this application, the third power component 11 is exemplarily described as an electric motor.

[0082] In some examples, the drive assembly 1 also includes a support base 14, to which the third power component 11, the first drive shaft 12, and the second drive shaft 13 are all connected. The support base 14 is connected to the chassis of the trunk 20. The support base 14 not only enables the connection between the drive assembly 1 and the chassis of the trunk 20, but also provides support and protection for the third power component 11, the first drive shaft 12, and the second drive shaft 13.

[0083] In some other embodiments, the drive assembly may include a third power member and a third drive shaft. The output shaft of the third power member is drively connected to one end of the third drive shaft, and the other end of the third drive shaft is drively connected to a transmission assembly. The axial direction of the third drive shaft is aligned with the width direction of the vehicle body structure, and the third drive shaft forms the output shaft of the drive assembly. It is understood that the drive assembly can also drive the transmission assembly in this way.

[0084] In some embodiments, the drive assembly 1 further includes a first engaging member and a second engaging member, the first drive shaft 12 includes a first engaging portion and a second engaging portion, the first engaging member is disposed on the output shaft of the third power member 11 and engages with the first engaging portion, and the second engaging member is disposed on the second drive shaft 13 and engages with the second engaging portion.

[0085] By having a first meshing member on the output shaft of the third power component 11 mesh with a first meshing part of the first transmission shaft 12, and a second meshing member on the second transmission shaft 13 mesh with a second meshing part of the first transmission shaft 12, the transmission connection between the third power component 11 and the first transmission shaft 12, and between the first transmission shaft 12 and the second transmission shaft 13, can be easily established, allowing the third power component 11 to smoothly transmit power to the transmission assembly 2. Furthermore, this meshing connection method provides accurate transmission and reliable performance, thereby improving the working performance of the drive assembly 1.

[0086] In some examples, the first meshing element and the first meshing portion can be a bevel gear transmission structure, a worm gear structure, etc. The second meshing element and the second meshing portion can also be a bevel gear transmission structure, a worm gear structure, etc.

[0087] In some embodiments, the vehicle body structure further includes a lifting assembly connected to the trunk chassis and to the load-bearing device, for driving the load-bearing device to move along the height direction of the vehicle body structure.

[0088] By incorporating a lifting assembly to move the carrier along the height of the vehicle body structure, the carrier can be switched from an extended to a retracted state when the drone is not in use. The lifting assembly then raises the carrier, along with the drone, to a position near the trunk chassis, increasing their height above the ground within the storage space. This increases the height of the carrier in its retracted state, preventing collisions with obstacles and damage to the carrier and drone during vehicle operation.

[0089] When a drone is needed, the carrier device, along with the drone, is moved a certain distance down along the height of the vehicle body structure. The carrier device then moves the drone to the underside or rear side of the rear bumper beam, making it easier for the carrier device to switch from a retracted state to an extended state, allowing the drone to take off or land.

[0090] In some examples, the lifting assembly includes an electric actuator or a hydraulic actuator, one end of which is connected to the trunk chassis, and the other end of which is connected to a drive assembly such as a support base, or may be connected to a transmission assembly such as a support member.

[0091] In some embodiments, see Figure 21 The support platform 3 includes a main structure 31 and a first conductive element 32 connected to the main structure 31; the drone 30 includes a body 301 and a second conductive element 302 connected to the bottom of the body 301; the first conductive element 32 and the second conductive element 302 are electrically connected to charge the drone 30.

[0092] By providing a first conductive element 32 on the support platform 3 and a second conductive element 302 on the drone 30, when the support device 10 is in a retracted state and the drone 30 is located on the support platform 3, the first conductive element 32 and the second conductive element 302 can be electrically connected to charge the drone 30 through the support device 10. This enhances the functionality of the support device 10 and facilitates the use of the drone 30.

[0093] In some examples, the first conductive element 32 and the second conductive element 302 may be aluminum strips, copper strips, or other conductive metal strips.

[0094] In some examples, the first conductive element 32 includes a first positive conductive element and a first negative conductive element, and the second conductive element 302 includes a second positive conductive element and a second negative conductive element. The first positive conductive element is electrically connected to the second positive conductive element, and the first negative conductive element is electrically connected to the second negative conductive element to charge the drone 30.

[0095] In some examples, the number of first conductive elements 32 can be multiple. Correspondingly, the number of first positive conductive elements and first negative conductive elements can also be multiple. This application does not make specific limitations on this.

[0096] In some embodiments, see Figure 21The support platform 3 also includes multiple protrusions 33 disposed on the main structure 31. The multiple protrusions 33 are spaced apart, and any two adjacent protrusions 33 and the main structure 31 form a water guide channel 34. Each protrusion 33 is provided with a first conductive element 32. By setting multiple protrusions 33 on the support platform 3 to form a water guide channel 34 with the main structure 31, water accumulated on the support platform 3 can be easily drained away from the support platform 3, keeping the support platform 3 clean and dry, and preventing short circuits when charging the drone 30 through the support platform 3.

[0097] In some examples, the multiple protrusions 33 include a first group of protrusions and a second group of protrusions. The arrangement direction of the first group of protrusions and the second group of protrusions is consistent with the arrangement direction of the multiple protrusions 33. Each protrusion 33 of the first group of protrusions is provided with a first positive conductive element, and each protrusion 33 of the second group of protrusions is provided with a first negative conductive element. In this way, after the drone 30 lands on the support platform 3, as long as at least one first positive conductive element and a second positive conductive element are electrically connected, and at least one first negative conductive element and a second negative conductive element are electrically connected, the drone 30 can be charged. This reduces the difficulty of connecting the charging connection when the drone 30 is parked and facilitates charging the drone 30.

[0098] In some examples, insulating strips may also be provided in the water guide channel 34 to isolate the multiple first positive conductive elements from each other, the multiple first negative conductive elements from each other, and adjacent first positive conductive elements and first negative conductive elements from each other, so as to improve the safety performance of the support platform 3.

[0099] In some embodiments, along the arrangement direction of the plurality of protrusions 33, the maximum size of the second conductive element 302 is greater than the maximum size of the water channel 34. This avoids a situation where, when the drone 30 is on the support platform 3, the second conductive element 302 is located exactly within the water channel 34, i.e., the second conductive element 302 is not in contact with the first conductive element 32, thus preventing the drone 30 from being charged, thereby improving the reliability of the charging function of the support platform 3. Taking the second conductive element 302 as an example, the maximum size of the second conductive element 302 refers to the maximum size of the second conductive element 302 along its entire length along the arrangement direction of the plurality of protrusions 33.

[0100] In some embodiments, along the arrangement direction of the plurality of protrusions 33, the maximum size of the second conductive element 302 is larger than the maximum size of the first conductive element 32. It is understood that this ensures the reliability of the electrical connection between the second conductive element 302 and the first conductive element 32 after the drone 30 lands on the support platform 3, that is, further improves the reliability of the charging function of the support platform 3.
