Please refer to... Figures 1-5 This application provides a tracked vehicle 100. The tracked vehicle 100 includes a frame, a transmission mechanism, a wheel assembly mechanism, and tracks. The frame includes a support body 101, a motor mounting bracket 102, and a wheel assembly mounting bracket 103. The transmission mechanism is arranged on the motor mounting bracket 102. The wheel assembly mechanism includes a drive sprocket 121, a support sprocket 122, a tension sprocket 123, and a trailing sprocket 124. The drive sprocket 121 is connected to the transmission mechanism, and the support sprocket 122, tension sprocket 123, and trailing sprocket 124 are respectively mounted on the wheel assembly mounting bracket 103. The tracks cover the support sprocket 122, trailing sprocket 124, and tension sprocket 123, and mesh with the drive sprocket 121. The motor mounting bracket 102 is connected to the support body 101 along the width direction, and the wheel assembly mounting bracket 103 is connected to the support body 101 along the length direction.
[0039] It is worth noting that the tracked vehicle 100 improves the overall structural strength and stability of the tracked vehicle 100 through the distributed design of the support body 101, the motor mounting bracket 102 and the wheel set mounting bracket 103. The motor mounting bracket 102 is arranged along the width direction to ensure the reliable installation of the motor 111 transmission mechanism, while the wheel set mounting bracket 103 is arranged along the length direction to provide sufficient space and stability for the installation and support of the wheel set.
[0040] In this embodiment, the wheel assembly mounting bracket 103 includes a support crossbar 1031 and a first vertical bar 1032. One end of the first vertical bar 1032 is connected to the support crossbar 1031, and the other end is rotatably connected to a drag wheel 124. The support wheel 122 is rotatably connected to the support crossbar 1031.
[0041] It is worth noting that by installing the track roller 124 and the support roller 122 on the first vertical rod 1032 and the support horizontal rod 1031 respectively, the track roller 124 and the support roller 122 can be located at the top and bottom of the wheel assembly mounting bracket 103 respectively, which facilitates the quick assembly and disassembly of the tracked vehicle 100 during assembly and subsequent maintenance, reducing maintenance costs and time.
[0042] Optionally, the wheel assembly mounting bracket 103 further includes a second vertical rod 1033, one end of which is connected to the support crossbar 1031 and the other end of which is connected to the bracket body 101; wherein, there are multiple first vertical rods 1032 and multiple second vertical rods 1033, and the multiple first vertical rods 1032 and multiple second vertical rods 1033 are arranged sequentially at intervals.
[0043] Specifically, one end of the second vertical rod 1033 is connected to the supporting horizontal rod 1031, and the other end is fixed to the bracket body 101, forming a multi-point support structure. This significantly improves the overall rigidity and stability of the wheel assembly mounting bracket 103, effectively withstanding the complex loads and impacts generated during the operation of the tracked vehicle 100. Simultaneously, the spaced arrangement of multiple first vertical rods 1032 and second vertical rods 1033 can reasonably distribute the forces on the supporting horizontal rod 1031 and the wheel assembly to the bracket body 101 and other connecting components, avoiding fatigue damage caused by excessive stress at a single point and extending the equipment's lifespan.
[0044] It should be understood that, as shown in the figure, there are three first vertical rods 1032 and two second vertical rods 1033. The two second vertical rods 1033 are arranged between two adjacent first vertical rods 1032. Depending on the specific implementation environment, there may also be four first vertical rods 1032 and three second vertical rods 1033, etc. It is also worth noting that in this embodiment, the length of the first vertical rods 1032 is greater than that of the second vertical rods 1033 to further improve the support effect on the towing wheel 124.
[0045] In this embodiment, the wheel assembly mounting bracket 103 further includes a fixing rod 1034 and a tensioning sleeve rod 1035. The fixing rod 1034 is connected to the first vertical rod 1032, and the tensioning sleeve rod 1035 is movably connected to the fixing rod 1034 along the length direction of the bracket body 101. The tensioning wheel 123 is rotatably connected to the tensioning sleeve rod 1035.
[0046] It is worth noting that this structural design allows the tension roller 123 to be used to adjust the tension and direction of the tracks; the support roller 122 can further support the weight of the vehicle body and reduce the pressure on the ground; and the trailing roller 124 can further help support the upper part of the tracks and prevent the tracks from loosening. These wheel sets work together to ensure that the tracked vehicle 100 can travel smoothly on various terrains.
[0047] In this embodiment, the transmission mechanism includes a motor 111, a reducer 112 and a coupling 113. The output shaft of the motor 111 is connected to the reducer 112, and the reducer 112 is connected to the drive wheel 121 through the coupling 113 to drive the drive wheel 121 to rotate.
[0048] It is worth noting that by directly driving the reducer 112 through the motor 111, the reducer 112 converts the high-speed, low-torque output of the motor 111 into a low-speed, high-torque driving force, which can efficiently transmit power and meet the driving requirements of the tracked vehicle 100 for the drive wheel 121. At the same time, the introduction of the coupling 113 can absorb a certain amount of vibration and impact during transmission, reduce the losses of the motor 111 and reducer 112 caused by load fluctuations, and improve the service life and reliability of the transmission system.
[0049] In this embodiment, the motor mounting bracket 102 includes a base plate 1021 and two side wing plates 1022. The two side wing plates 1022 are respectively connected to the two sides of the base plate 1021, and each side wing plate 1022 has a through hole 1023.
[0050] It is worth noting that the base plate 1021 and the two side flanges 1022 form a three-sided covering structure, effectively covering components such as the motor 111 and coupling 113, providing mechanical protection, preventing the intrusion of dust, mud, and other foreign objects, and improving the durability and reliability of the equipment. Simultaneously, the three-sided support structure can more firmly fix the motor 111, reducing the risk of vibration and displacement during operation, thereby ensuring the working stability of the transmission mechanism. Furthermore, the through hole 1023 on the side flange 1022 provides an operating channel for the installation, adjustment, and connection of the coupling 113, allowing for quick docking of the coupling 113 with the motor 111 and reducer 112 without disassembling the support, significantly improving installation efficiency. This structural design also facilitates observation of the installation position and alignment of the coupling 113, supporting rapid adjustments during installation or operation. At the same time, maintenance does not require extensive disassembly of the support, simplifying the operation process.
[0051] Optionally, the tracked vehicle 100 also includes an upper cover plate 13, which is installed on the top of the support body 101 to seal the accommodating chamber formed by the support body 101 itself. A guardrail 131 is installed on the side of the upper cover plate 13 facing away from the support body 101.
[0052] Specifically, the upper cover plate 13 encloses the cavity, effectively isolating it from the intrusion of dust, mud, rainwater, and other external pollutants, protecting the internal mechanical and electrical components from environmental influences, and extending the equipment's lifespan. Simultaneously, as the top cover of the support body 101, the upper cover plate 13 increases the overall rigidity and strength of the vehicle structure, enhancing the tracked vehicle 100's resistance to deformation under harsh working conditions.
[0053] In this embodiment, a lighting lamp 132 and / or a lidar 133 are installed on the upper cover plate 13. It is understood that the lighting lamp 132 and lidar 133 can enhance the versatility of the tracked vehicle 100 and further improve its applicability.
[0054] In this embodiment, the tracked vehicle 100 also includes a guard plate 14, which is installed on one side of the wheel assembly mounting bracket 103 to seal the wheel assembly mechanism.
[0055] In this embodiment, the tracked vehicle 100 also includes a cover panel 15, which covers the motor mounting bracket 102 to seal the transmission mechanism. The outer surface of the cover panel 15 facing away from the motor mounting bracket 102 also has a UWB module 16.
[0056] It is worth noting that the protective plate 14, the cover panel 15, and the upper cover plate 13, as coverings, can be used to protect the internal mechanical structure, electrical equipment, and other parts of the tracked vehicle 100 from the influence of the external environment. These coverings can be made of metallic materials, giving them good weather resistance and corrosion resistance. They not only protect internal components from natural factors such as dust, moisture, and ultraviolet radiation, but also enhance the overall appearance design of the vehicle.
[0057] Finally, it should be understood that the foregoing embodiments in this specification are merely illustrative of the principles of the embodiments described herein. Other variations may also fall within the scope of this specification. Therefore, alternative configurations of the embodiments in this specification are considered as examples and not limitations, and are regarded as consistent with the teachings of this specification. Accordingly, the embodiments in this specification are not limited to those explicitly described and illustrated herein.
