Description

Technical Field

[0001] This utility model relates to the field of unmanned vehicles, and in particular to a generator with a buffering effect for unmanned vehicles. Background Technology

[0002] With the rapid development of autonomous driving technology, unmanned vehicles are being used more and more widely in many fields such as logistics and delivery, industrial operations, and special missions. In actual driving, unmanned vehicles often face complex and diverse road conditions, such as rugged mountain roads, urban speed bumps, and potholes, which inevitably subject them to continuous vibrations or instantaneous impacts.

[0003] As a key component for emergency power supply of unmanned vehicles, the stability of the range-extended generator directly affects the overall performance of the unmanned vehicle.

[0004] In traditional installation methods, the generator is directly fixed to the vehicle frame using rigid components such as bolts. The impact forces generated by road bumps, emergency braking, or collisions during the operation of the unmanned vehicle, including vertical bump forces, lateral centrifugal forces during turning, and instantaneous collision impact forces, are directly transmitted along the path of vehicle frame → mounting bolts → generator housing. Without a buffer structure to attenuate energy, under continuous or high-frequency vibration, external forces repeatedly act on the generator, causing the mechanical structure to bear alternating loads for a long time, accelerating fatigue damage. Therefore, a generator with a buffer effect for unmanned vehicles is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-3This utility model provides an embodiment of a generator with a buffer effect for unmanned vehicles, comprising an unmanned vehicle 1 and a generator 3, and consisting of a battery system, a range extender system, and a remote control system. The battery system mainly consists of lithium batteries / maintenance-free lead-acid batteries, a battery manager, a power detector, a charging device, etc. This technology is prior art, therefore it will not be described in detail. An installation assembly 2 is mounted on the rear inner wall of the unmanned vehicle 1, and the generator 3 is installed inside the installation assembly 2. The generator 3 is a range extender generator. The installation assembly 2 includes a base 21 fixedly mounted on the inner wall of the unmanned vehicle 1, providing a stable mounting foundation for the entire installation assembly 2 and ensuring a firm connection between the installation assembly 2 and the unmanned vehicle 1. Multiple sets of guide posts are welded to the upper part of the base 21. 22 provides guidance for the sliding of the support plate 23, ensuring that the support plate 23 remains stable during up and down movement and does not deviate. Two sets of support plates 23 are slidably connected to the outer side of the multiple sets of guide columns 22, which together support the generator 3. The generator 3 is fixedly installed on the upper part of the lower set of support plates 23, and a connector 29 is fixedly connected to the lower part of the upper set of support plates 23, so that the generator 3 and the support plate 23 can transmit force. The connector 29 is sleeved on the outer side of the generator 3. The top of the multiple sets of guide columns 22 is fixedly installed with mounting plates 24 by bolts 26, which cooperate with the base 21 and are connected to the support plate 23 by spring dampers 25 to form a complete mounting frame. At the same time, it is installed by bolts 26, which facilitates disassembly and maintenance.

[0031] Reference Figure 2 , Figure 3 and Figure 5The two sets of support plates 23 are connected to the mounting plate 24 and the base 21 respectively by multiple sets of spring dampers 25 on the upper and lower sides. The springs can absorb vibration energy through elastic deformation, and the damping effect of the dampers can consume vibration energy, reduce the transmission and duration of vibration, thereby playing a buffering and shock-absorbing role for the generator 3. The two sets of spring dampers 25 are symmetrically inclined, which can make the buffering force distribution more uniform, improve the overall buffering effect, and better cope with vibrations and impacts from different directions. A buffer cylinder b28 is sleeved on the outer side of the middle of the guide post 22, and a buffer cylinder a27 is sleeved at the end of the guide post 22. The buffer cylinder b28 and the buffer cylinder a27 are made of rubber. The buffer cylinder b28 consists of multiple sets of spring dampers 25. The system consists of identical buffer cylinders a27 and buffer cylinder b28, which is stored outside the guide post 22 as a spare. These provide buffering at different locations on the guide post 22, enhancing the buffering effect. Both the inner and outer sides of the buffer cylinders a27 and b28 are provided with annular grooves, increasing the elastic deformation space. When the guide post 22 is impacted, it can absorb energy through its own elastic deformation, playing an auxiliary buffering role and further improving the overall buffering effect. Two sets of connectors 29 are provided, which are fitted on the left and right sides of the generator 3 to stably transmit the vibration of the generator 3. The mounting plate 24 and the base 21 have a through groove in the middle to accommodate the movement of the spring damper 25.

[0032] Reference Figure 3 and Figure 4 The inner wall of the mounting plate 24 is provided with an auxiliary component 4. The auxiliary component 4 includes multiple sets of moving parts 41 that are slidably connected to the inner wall of the mounting plate 24. A compression spring 43 is provided on the opposite side of two adjacent sets of moving parts 41. By cooperating with the compression spring 43, the two adjacent sets of moving parts 41 can drive the baffle 42 to be stably inserted above the bolt 26, thereby limiting and protecting the bolt 26, preventing the bolt 26 from loosening or even falling off, and ensuring that the connection between the mounting plate 24 and the guide post 22 is firm, thereby ensuring the stability and reliability of the entire mounting component 2. A baffle 42 is fixedly connected on the opposite side of two adjacent sets of moving parts 41. The baffle 42 is located above the bolt 26 and is designed as a long plate.

[0033] Working principle: During use, the two sets of support plates 23 are connected to the mounting plate 24 and the base 21 through multiple sets of spring dampers 25. When the unmanned vehicle 1 encounters bumps or impacts while driving, the generator 3 is displaced along with the support plates 23: the adjacent spring dampers 25 are symmetrically tilted, so that the buffering force is evenly distributed in the horizontal and vertical directions. The spring part of the spring damper 25 absorbs the vibration energy through elastic deformation, converting mechanical energy into elastic potential energy, reducing the amplitude of vibration transmitted to the generator 3.

[0034] The buffer cylinder a27, fitted onto the guide post 22, has annular grooves on its inner and outer sides that increase the space for elastic deformation. When the guide post 22 slides with the support plate 23, the buffer cylinder is compressed and deformed, absorbing residual vibration energy through its own elasticity and further attenuating the vibration amplitude, such as high-frequency small-amplitude vibration. The buffer cylinder b28 is a spare part that can be replaced when the buffer cylinder a27 is damaged.

[0035] In the auxiliary component 4 on the inner wall of the mounting plate 24, a baffle 42 is positioned above the bolt 26. When the unmanned vehicle 1 vibrates, causing the bolt 26 to loosen, the compression spring 43 pushes the moving part 41, making the baffle 42 press tightly against the head of the bolt 26, thus mechanically preventing the bolt 26 from rotating or falling off. During vibration, the baffle 42 compresses the spring 43 slightly, but the elastic force of the spring 43 will promptly reset it, continuously providing a limiting force. During disassembly and maintenance, the bolt 26 can be loosened by manually pushing the baffle 42 open, without affecting the ease of disassembly of the mounting component 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
