Technical Field
[0001] This utility model relates to the field of automotive special equipment technology, specifically to an automobile with an adjustable bumper height. Background Technology
[0002] When a vehicle collides, the bumper absorbs and cushions the impact, distributing the force to other parts of the vehicle body and protecting the safety of the front and rear of the vehicle as well as the occupants. For example, in low-speed collisions, it can effectively reduce the damage to vehicle components; in high-speed collisions, it can also reduce injuries to occupants to some extent. Furthermore, it also provides some protection in collisions between vehicles and pedestrians, reducing the severity of pedestrian injuries.
[0003] Currently, all bumpers use a fixed structure, and the ground clearance cannot be adjusted. The departure angle of the car is a fixed value. When there are road surface slopes that change significantly or rough, uneven surfaces, the departure angle may be insufficient, causing the bumper to hit the ground and be damaged, or the car may be unable to pass through the road surface.

[0059] Please see Figures 1 to 6 This embodiment relates to a car with an adjustable bumper 2 height, including:
[0060] Chassis 1; Chassis 1 is the basic component of a car, used to support the various parts of the car, bear the load of the car, and transmit power to the wheels to ensure the normal driving of the car.
[0061] Bumper 2, originally installed at the rear of a car, is a structural component used to absorb and buffer impact forces during a collision, and is a core part of the rear bumper 2. In this embodiment, the bumper 2 retains the basic protective functions of a traditional bumper 2, ensuring effective protection of the vehicle and occupants during a collision, providing a fundamental guarantee for safe driving.
[0062] The bumper 2 is fixedly mounted at one end to the bottom of the vehicle body 5. The bumper 2 includes a crossbeam 21 and a lifting assembly 22. The crossbeam 21 is arranged in a transverse direction, which is perpendicular to the longitudinal direction of the vehicle body. As the main load-bearing component of the bumper 2, the crossbeam 21 can withstand and transmit impact forces during a collision. The lifting assembly 22 is arranged in a longitudinal direction, which is the height direction of the vehicle body. One end of the lifting assembly 22 is fixedly mounted to the bottom of the vehicle body 5, and the other end is fixedly connected to the crossbeam 21. The lifting assembly 22 is used for vertical lifting movement; its main function is to provide guidance and support for the lifting of the crossbeam 21, ensuring stable vertical movement of the crossbeam 21.
[0063] The drive mechanism 3 is movably connected at one end to the chassis 1 and at the other end to the crossbeam 21. The movable connection can be a hinge or the like, allowing the drive mechanism 3 to rotate flexibly and thus better drive the crossbeam 21 to rise and fall. The drive mechanism 3 is used to drive the crossbeam 21 to rise and fall in the vertical direction. The drive mechanism 3 is a power transmission component that realizes the height adjustment of the crossbeam 21.
[0064] The system also includes a power mechanism 4, which provides power to the drive mechanism 3, providing an energy source for the operation of the drive mechanism 3 and ensuring that the drive mechanism 3 can normally drive the beam 21 to rise and fall. The power mechanism 4 can be a hydraulic system or an electric system.
[0065] Specifically, in this embodiment of the car with adjustable bumper 2, when the vehicle is driving on a road surface with a large change in slope or a rough, uneven surface, the power mechanism 4 provides power to the drive mechanism 3. The drive mechanism 3 drives the crossbeam 21 of the bumper 2 to rise vertically. By adjusting the height of the bumper 2, the departure angle can be increased, preventing the crossbeam 21 of the bumper 2 from hitting the ground and being damaged. At the same time, it ensures that the vehicle can pass through the road surface smoothly, greatly improving the vehicle's passability in complex road conditions. After passing through the road surface, the drive mechanism 3 drives the crossbeam 21 of the bumper 2 to descend vertically, realizing the vertical height adjustment of the bumper 2 to adapt to complex road surfaces.
[0066] Optionally, in some embodiments, such as Figures 1 to 5As shown, the height-adjustable bumper 2 of the vehicle also includes a cargo box 5, which is mounted on the chassis 1; the cargo box 5 can be used to store equipment components. One end of the lifting assembly 22 is fixedly disposed at the bottom of the rear end of the cargo box 5, and one end of the drive mechanism 3 is movably connected to the main beam 11 of the chassis 1. The main beam 11 of the chassis 1 is a rigid structure that plays a major load-bearing role in the chassis 1. The main beam 11 of the chassis 1 has high strength and rigidity, providing reliable support for the drive mechanism 3 and ensuring that the drive mechanism 3 can stably exert force when driving the crossbeam 21 to rise and fall, thus improving the reliability of the entire drive system. Fixing the lifting assembly 22 to the bottom of the cargo box 5 makes the installation of the lifting assembly 22 more stable, reducing swaying during the lifting process and ensuring the smoothness of the bumper 2's rise and fall. The drive mechanism 3 is connected to the main beam 11 of the chassis 1, utilizing the high strength characteristics of the main beam 11 to enhance the stability and reliability of the drive mechanism 3 during operation and extend the service life of the drive mechanism 3.
[0067] Optionally, in some embodiments, such as Figures 1 to 5 As shown, the carriage 5 includes a base frame 51 and a body 52. The base frame 51 is mounted on the chassis 1, and the body 52 is mounted on the base frame 51. The base frame 51 is the frame structure at the bottom of the carriage 5; the body 52 is the main body of the carriage 5, used to form the loading space. One end of the lifting assembly 22 is fixedly installed at the bottom of the rear end of the base frame 51. The base frame 51 enhances the overall strength and load-bearing capacity of the carriage 5. Fixing the lifting assembly 22 to the bottom of the rear end of the base frame 51 makes the installation position of the lifting assembly 22 more reasonable, facilitating precise lifting control of the bumper 2 crossbeam 21, and also ensuring the stability and reliability of the lifting assembly 22 during operation.
[0068] Specifically, in this embodiment, such as Figures 1 to 5 As shown, the power unit 4 is housed within the cargo box 52; this utilizes the space inside the cargo box 52, preventing the power unit 4 from being exposed to the external environment and reducing the impact of external factors. Alternatively, in other embodiments, the power unit 4 is located at the bottom of the underframe 51, fully utilizing the unused space below the underframe 51 without occupying the loading space inside the cargo box 52. Specifically, multiple installation positions for the power unit 4 are provided, allowing for flexible arrangement based on the actual vehicle layout and usage requirements. Positioning it inside the cargo box 52 provides some protection for the power unit 4, reducing its erosion from dust, rain, etc.; positioning it at the bottom of the underframe 51 does not occupy the loading space of the cargo box 52, improving the loading efficiency of the cargo box 5.
[0069] Optionally, in some embodiments, such as Figures 1 to 5As shown, the lifting assembly 22 includes a fixed tube 221 and a lifting rod 222. The fixed tube 221 is a hollow tubular structure with one end fixed; the lifting rod 222 is a rod-shaped structure that can slide within the fixed tube 221. One end of the fixed tube 221 is bolted to the carriage 5, providing a fixed foundation for the entire lifting assembly 22. One end of the lifting rod 222 is fixedly connected to the crossbeam 21, and the other end of the lifting rod 222 is embedded in the other end of the fixed tube 221, with the lifting rod 222 slidably connected to the fixed tube 221. When the drive mechanism 3 drives the crossbeam 21 to rise or fall, the lifting rod 222 slides within the fixed tube 221, thereby achieving vertical lifting of the crossbeam 21. The bolted connection facilitates the installation and disassembly of the fixed tube 221, and facilitates later maintenance and replacement.
[0070] Optionally, in some embodiments, such as Figures 1 to 5 As shown, there are at least two lifting components 22, spaced apart, with their other ends fixedly connected to the crossbeam 21. There are also at least two driving mechanisms 3, spaced apart, with their other ends movably connected to the crossbeam 21. "At least two" indicates a quantity of no less than two; "spaced apart" means there is a certain distance between the components. The spaced arrangement of multiple lifting components 22 and their fixed connection to the crossbeam 21 provides support from multiple points, ensuring uniform force distribution on the crossbeam 21 during lifting and preventing tilting or damage due to uneven force. The spaced arrangement of multiple driving mechanisms 3 and their movable connection to the crossbeam 21 allows for the application of driving force to the crossbeam 21 from multiple positions, making the lifting and lowering of the crossbeam 21 more stable and reliable, and improving the synchronization and stability of the lifting and lowering of the crossbeam 21. The inclusion of at least two lifting components 22 and a drive mechanism 3 enhances the support and driving effect on the crossbeam 21, making the crossbeam 21 more stable during lifting and lowering, reducing the swaying and deformation of the crossbeam 21, improving the overall structural strength and service life of the bumper 2, and ensuring that the bumper 2 can perform its protective function normally at different height positions.
[0071] Optionally, in some embodiments, such as Figures 1 to 5As shown, the power mechanism 4 is a hydraulic power mechanism 4, and the drive mechanism 3 is a drive cylinder. One end of the drive cylinder is movably connected to the main beam 11 of the chassis 1 through a cylinder seat, and the other end of the drive cylinder is movably connected to the crossbeam 21 through a cylinder seat. The hydraulic power mechanism 4 is a device that provides power using hydraulic principles; the drive cylinder is an actuator that converts hydraulic energy into mechanical energy. The hydraulic power mechanism 4 provides high-pressure hydraulic oil to the drive cylinder, which then extends and retracts under the action of the hydraulic oil. Since one end of the drive cylinder is movably connected to the main beam 11 of the chassis 1, and the other end is movably connected to the crossbeam 21, when the drive cylinder extends and retracts, it drives the crossbeam 21 to rise and fall vertically. Hydraulic transmission has the characteristics of large output force, smooth transmission, and fast response speed, which can meet the power requirements for the raising and lowering of the bumper 2. Using the hydraulic power mechanism 4 and the drive cylinder as the power and drive devices makes the raising and lowering operation of the bumper 2 more stable and reliable, with a large driving force, easily driving the crossbeam 21 to rise and fall. Meanwhile, the hydraulic transmission has a fast response speed, enabling rapid adjustment of the bumper 2 height and improving the vehicle's ability to cope with complex road conditions. The drive mechanism 3 can also be an electric cylinder or a pneumatic cylinder.
[0072] Optionally, in some embodiments, such as Figures 1 to 6 As shown, the height-adjustable bumper 2 of the car also includes a distance detection mechanism 6 and a control system 7. The distance detection mechanism 6 is located at the bottom of the crossbeam 21 and is electrically connected to the control system 7. The power mechanism 4 is also electrically connected to the control system 7. The distance detection mechanism 6 is used to detect the ground clearance of the crossbeam 21. The control system 7 is used to receive and process the detection signal from the distance detection mechanism 6 and control the start and stop of the power mechanism 4. The distance detection mechanism 6 is a device capable of measuring the distance between an object and the ground; in this embodiment, it is a distance sensor. The control system 7 is a device that controls and coordinates the entire system.
[0073] Specifically, the distance detection mechanism 6 is installed at the bottom of the crossbeam 21 to detect the ground clearance of the crossbeam 21 in real time and transmits the detected signal to the control system 7. After receiving the signal, the control system 7 processes it. When the detected ground clearance does not meet the requirements of the current road conditions, the control system 7 sends a command to the power mechanism 4 to start or stop it. This, in turn, adjusts the height of the crossbeam 21 through the drive mechanism 3, keeping the crossbeam 21 at a suitable ground clearance. This achieves automatic adjustment of the bumper 2 height without manual operation, improving the vehicle's intelligence. The distance detection mechanism 6 can accurately detect the ground clearance, and the control system 7 can promptly control the power mechanism 4 based on the detection results, allowing the bumper 2 height to quickly adapt to changes in road conditions, further improving the vehicle's passability and safety, and reducing the driver's operating difficulty.
[0074] Specifically, in this embodiment of the car with an adjustable bumper 2, a distance detection mechanism 6 is installed at the bottom of the crossbeam 21 to detect the ground clearance of the crossbeam 21 in real time. When the vehicle is driving on a road surface with a large gradient or a rough, uneven surface, if the distance detection mechanism 6 detects a ground clearance of less than 200mm, the distance detection mechanism 6 transmits the detected signal to the control system 7. The control system 7 analyzes and processes the signal, and then controls the hydraulic power mechanism 4 to operate via a control line, driving the drive mechanism 3 in this embodiment to move, thereby causing the crossbeam 21 of the bumper 2 to move upward. By adjusting the height of the bumper 2, the departure angle can be increased, preventing the crossbeam 21 of the bumper 2 from hitting the ground and being damaged. At the same time, it ensures that the vehicle can pass through the road surface smoothly, greatly improving the vehicle's passability in complex road conditions. After passing through the road surface, the drive mechanism 3 drives the crossbeam 21 of the bumper 2 to descend vertically, realizing the height adjustment of the bumper 2 in the vertical direction to adapt to complex road surfaces. When the distance detection mechanism 6 detects that the distance from the ground reaches 450mm, the distance detection mechanism 6 transmits the detected signal to the control system 7. The control system 7 analyzes and processes the signal, and then controls the hydraulic power mechanism 4 to stop running through the control line. The drive mechanism 3 also stops moving, thereby ensuring that the bumper 2 crossbeam 21 is at a relative height from the ground.
[0075] Optionally, in some embodiments, such as Figures 1 to 4 As shown, the rear end of the carriage 5 is equipped with an upward-opening door 53 and a downward-opening door 54. The upward-opening door 53 is located above the downward-opening door 54. The top of the upward-opening door 53 is hinged to the top of the carriage body 52 of the carriage 5, and the bottom of the downward-opening door 54 is hinged to the bottom of the carriage body 52 of the carriage 5. The top of the upward-opening door 53 is hinged to the top of the carriage body 52 and can be opened by flipping upwards; the bottom of the downward-opening door 54 is hinged to the bottom of the carriage body 52 and can be opened by flipping downwards. The upward-opening door 53 and the downward-opening door 54 facilitate the loading and unloading of goods in the carriage 5. When loading and unloading goods are required, the upward-opening door 53, the downward-opening door 54, or both can be opened, depending on the size of the goods and the loading and unloading method. This improves the convenience and flexibility of loading and unloading goods in the carriage 5 and adapts to different loading and unloading needs. At the same time, the door design also ensures the airtightness of the carriage 5, protecting the goods inside the carriage 5 from the influence of the external environment when not loading or unloading goods. Furthermore, this design does not interfere with the lifting structure of bumper 2, ensuring the normal functioning of both.
[0076] Optionally, in some embodiments, such as Figures 1 to 3As shown, the height-adjustable bumper 2 of the vehicle also includes a driver's cab 8 and a mounting bracket 9. The driver's cab 8 is located on the front end of the chassis 1, and the mounting bracket 9 is located on the top of the driver's cab 8. The mounting bracket 9 is used to install and place items (spare tire, water hose, oil pipe, etc.). By providing the mounting bracket 9, the space on top of the driver's cab 8 is fully utilized, increasing the vehicle's storage space and functional expandability. This meets the user's needs for placing more items or installing auxiliary equipment, improving the vehicle's practicality and multi-functionality.
[0077] The car with an adjustable bumper 2 in this embodiment has the following beneficial effects:
[0078] Under normal driving conditions, the ground clearance of the bumper body 2 is no more than 500mm.
[0079] Improved traffic capacity: By adjusting the height of the bumper 2 body, the departure angle of the vehicle can be increased under complex road conditions, avoiding damage to the bumper 2 from hitting the ground, and enabling the vehicle to pass smoothly through complex road surfaces such as rugged terrain and steep slopes, thus significantly improving the vehicle's traffic capacity.
[0080] Ensuring protective performance: The bumper 2 body retains the collision protection function of the traditional bumper 2, which can effectively absorb and buffer the impact force in the event of a collision, protecting the safety of the vehicle and people.
[0081] Easy to operate: Through the control system 7, the driver can easily and quickly adjust the height of the bumper 2 to adapt to different road conditions, improving the vehicle's handling and ease of use.
[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
