Description

Technical Field

[0001] This invention relates to the field of engineering vehicle technology, and more particularly to a tracked vehicle. Background Technology

[0002] Tracked vehicles possess good off-road performance. The tracks on their tracked chassis distribute the vehicle's weight, reducing the unit pressure on the ground and enhancing traction and mobility. However, on existing tracked vehicles, the track plates are rigidly mounted on the track chains. When traversing deep mud and swamps, the track plates lack sufficient grip and are prone to slipping in the mud, failing to generate enough propulsion to extricate themselves from difficult situations. Summary of the Invention

[0003] The purpose of this invention is to provide a tracked vehicle that can travel in deep silt, avoiding or reducing slippage in the silt.

[0004] The technical solution of the present invention is: a tracked vehicle, including an upper frame and a tracked chassis mounted on the upper frame. The tracked chassis includes track plates, a housing, track sprockets rotatably disposed at the front and rear ends of the housing, and a track chain rotating around the track sprockets. The upper frame is mounted on the housing. The track plates are evenly distributed along the track chain. A first mounting plate is provided on the track chain. A second mounting plate is connected to the first mounting plate. The track plates are mounted on the second mounting plate. The mounting position of the second mounting plate on the first mounting plate is adjusted to adjust the angle of the track plates.

[0005] Preferably, the first mounting plate is vertically mounted on the track chain; the first mounting plate is provided with at least two first mounting holes, and the second mounting plate is provided with multiple second mounting holes, wherein at least two first mounting holes are aligned with some of the second mounting holes for installation, so as to achieve adjustment of the track plate angle.

[0006] Preferably, one side of the track chain is rotatably mounted on a roller via a third mounting plate, and the roller makes rolling contact with the bottom surface of the housing.

[0007] Preferably, the rollers are arranged in a one-to-one correspondence with the track plates.

[0008] Preferably, the deflection angles of the plurality of track plates are consistent.

[0009] Preferably, the track sprocket has a shaft, which is mounted on the housing via a bearing seat. The track sprocket at one end of the track chassis is connected to the drive mechanism, and the track sprocket at the other end of the track chassis has a tensioning mechanism connected between the track chassis and the bearing seat.

[0010] Preferably, the tensioning mechanism is a bolt threadedly connected to the track chassis, and the bolt head is connected to the bearing seat.

[0011] Preferably, the drive mechanism includes a motor mounted on the upper frame, a reducer connected to the power output end of the motor, a drive sprocket connected to the power output end of the reducer, a transmission sprocket coaxially mounted with the track sprocket, and a transmission chain connecting the drive sprocket and the transmission sprocket.

[0012] Preferably, the upper frame is equipped with a battery and an electronic control box that are electrically connected to the drive mechanism.

[0013] Preferably, the housing has a sealed cavity inside. The housing with the cavity generates buoyancy, allowing the tracked vehicle to float on water. Simultaneously, the sealed housing can be integrated into the tracked chassis, providing mounting points for various components and offering rigid support.

[0014] Compared with related technologies, the beneficial effects of the present invention are as follows: 1. The present invention allows for adjustable installation of track plates via a first mounting plate and a second mounting plate, enabling multiple angle installations between the track plates and the track chain. This allows the track plates to generate forward and upward propulsion forces when they are inserted into the mud, driving the tracked vehicle to quickly get out of trouble and prevent it from getting stuck in the mud. Second, this invention enables different installation angles of the track plates, making tracked vehicles better suited for driving on flat ground, sand, and water, thus improving their applicability and versatility. Thirdly, this invention features rollers installed inside the track chain, which can contact the bottom surface of the housing and roll freely. These rollers transmit the pressure on the track chain to the housing, ensuring smooth operation of the track chain. Fourth, the box body has a box-shaped structure with a sealed cavity inside, which can generate a large benefit in water, ensuring that the tracked vehicle can float on the water surface.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" used below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0018] like Figure 1 , Figure 2 As shown, the tracked vehicle provided in this embodiment includes a tracked chassis 1, a chassis 2, a battery 3, an electrical control box 4, and a drive mechanism 5.

[0019] The tracked chassis 1 includes a housing 11, track sprockets 12, track chains 13, a first mounting plate 14, a second mounting plate 15, track plates 16, a third mounting plate 17, rollers 18, shafts 19, bearing seats 110, and a tensioning mechanism 111.

[0020] The box 11 has a box-shaped structure with a sealed cavity inside, which can generate a large buoyancy in water, ensuring that the tracked vehicle can float on the water surface.

[0021] The track sprocket 12 has a shaft 19. Both the front and rear ends of the housing 11 have bearing seats 110 for mounting the shaft 19. One end of the track sprocket 12 is driven by the drive mechanism 5, and the other end of the track sprocket 12 is equipped with a tensioning mechanism 111. The tensioning mechanism 111 is a bolt threaded to the track chassis 1. The bolt head is connected to the bearing seat 110, and the bearing seat 110 at this position connects to a slotted hole on the housing 11 to provide leeway for positional changes in the bearing seat 110. The track chain 13 is tensioned by adjusting the tensioning mechanism 111.

[0022] The drive mechanism 5 includes a motor 51 mounted on the upper frame 2, a reducer 52 connected to the power output end of the motor 51, a drive sprocket 55 connected to the power output end of the reducer 52, a transmission sprocket 54 coaxially mounted with the track sprocket 12, and a transmission chain 53 connecting the drive sprocket 55 and the transmission sprocket 54.

[0023] The motor 51 rotates forward and backward to transmit power to the drive sprocket 54 via the drive chain 53, which drives the track sprocket 12 to run. This drives the track sprocket 12 at the other end via the track chain 13, allowing the tracked vehicle to move forward or backward.

[0024] like Figure 1 As shown, the drive mechanism 5, track sprockets 12, and track chains 13 are arranged in two sets along the width of the housing 11. Each set has two track sprockets 12 and two track chains 13.

[0025] like Figure 2 As shown, the track plates 16 are evenly distributed along the track chain 13. Figure 3 , Figure 4 As shown, a first mounting plate 14 is vertically mounted on the outer side of each track chain 13. The first mounting plate 14 is L-shaped, with its short side connected to the hole in the track chain 13 by bolts, and its long side having two first mounting holes 141. Each first mounting plate 14 is equipped with a second mounting plate 15. The track plate 16 is simultaneously mounted on two second mounting plates 15.

[0026] The second mounting plate 15 has multiple second mounting holes 151. After the first mounting hole 141 is aligned with the second mounting holes 151 at different positions, it is installed by bolts to allow adjustment of the track shoe 16 mounting angle (e.g., ...). Figure 5 , Figure 6 , Figure 7 (As shown). By using different mounting hole positions, the track shoes 16 can be connected at various angles. In practice, depending on the working conditions, the track shoes 16 are adjusted to a suitable mounting angle to generate forward or upward propulsion during the operation of the tracked vehicle, making it less likely for the tracked vehicle to get stuck in mud. Figure 2 As shown, the deflection angles of the multiple track plates 16 are consistent.

[0027] A third mounting plate 17 connects the two track chains 13 in the same group. A roller 18 is rotatably mounted on the third mounting plate 17, and the roller 18 and track plates 16 are respectively located on opposite sides of the track chains 13. The roller 18 and track plates 16 are arranged in a one-to-one correspondence. When the roller 18 rotates to the lower side with the track chain 13, the roller 18 makes rolling contact with the bottom surface of the housing 11. The roller 18 rolls freely along the housing 11, transmitting the pressure on the track chain 13 to the housing 11, ensuring smooth operation of the track chain 13.

[0028] The upper frame 2 is a portal frame structure, bolted to the side surface of the housing 11. The electrical control box 4, battery 3, and motor 51 of the drive mechanism 5 are mounted on the upper end of the upper frame 2. The battery 3 is electrically connected to the electrical control box 4 and motor 51 to provide power. The electrical control box 4 can control the forward and reverse rotation of motor 51, and can also remotely control the operation of motor 51 using a remote control. Motor 51 is a geared motor, and its output power drives the transmission sprocket 54 and track sprocket 12 through the transmission chain 53.

[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
