Description

Technical Field

[0001] This utility model relates to the field of water propulsion technology, and more specifically, it relates to a novel water propulsion steering control device. Background Technology

[0002] Amphibious vehicles are vehicles that can navigate on water independently without the need for pontoon bridges, ferries, or other auxiliary equipment. Amphibious vehicles typically use water jet propulsion as their power source for water navigation. Because amphibious vehicles need to have a certain degree of off-road and obstacle-crossing capabilities, components such as water jet propulsion are located inside the vehicle's cabin.

[0003] Chinese Patent Publication No. CN112874745A, published on June 1, 2021, discloses an invention entitled "Nozzle Device for a Waterjet Propulsion Device." This nozzle device includes: a connecting nozzle with a connecting end; a steering nozzle comprising a first steering pipe segment and a second steering pipe segment connected together, the central axes of the first and second steering pipe segments forming an angle of not less than 90 degrees, the first steering pipe segment being rotatably connected to the connecting end and sealed in communication with the connecting end; and a drive assembly located on the connecting nozzle, the drive assembly being configured to drive the first steering pipe segment to rotate. This application enables rapid control of amphibious vehicles for turning and reversing, without significant energy loss during turning and reversing, thus maintaining the amphibious vehicle's speed.

[0004] However, the above structure controls the direction of the nozzle through a power component, which is prone to failure when immersed in water for a long time; moreover, the overall structure of the above-mentioned nozzle control method is complex. Utility Model Content

[0005] This invention overcomes the problem in existing technologies that use power components to control steering, where the power components are prone to failure due to prolonged immersion in water. It provides a novel water propulsion steering control device that achieves steering control through a purely mechanical structure. This device features a simple structure, high operability and stability, and an improved service life.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a novel water propulsion and steering control device, comprising:

[0008] Rotate the steering nozzle mounted on the pump body;

[0009] The horizontal control lever connected to the steering nozzle;

[0010] The steering lever and the lateral control lever are connected by a transmission assembly.

[0011] This application achieves steering control by pulling the steering lever, which swings forward or backward around the fulcrum. The transmission component drives the lateral control lever to move laterally, and finally drives the steering nozzle to rotate in different directions. All structures are implemented using a purely mechanical structure, which has the characteristics of simple structure, strong operability and stability, and can improve service life.

[0012] Preferably, the system also includes a joystick bracket, on which a rotating shaft is rotatably mounted; the steering joystick is fixedly connected to the rotating shaft.

[0013] The mounting holes on the horizontal plate are for easy installation of the joystick bracket on related equipment, such as the frame of an amphibious special vehicle.

[0014] Preferably, the transmission assembly includes a steering tie rod, one end of which is fixedly provided with a transmission head, and the other end of which is fixedly provided with a connector; the transmission head is rotatably connected to the steering lever, and the connector is rotatably connected to the lateral control lever.

[0015] The steering tie rod transmits power from the steering lever to the lateral control lever.

[0016] Preferably, the transmission head includes a center plate and side plates arranged parallel to both sides of the center plate; a central hole is provided through the center plate, and the central hole is threaded to the end of the steering tie rod; a side hole is provided through the side plate, and the transmission bolt passes through the two side holes and is connected to the nut, and the steering control lever is rotatably mounted on the transmission bolt.

[0017] Furthermore, the central hole in this application is connected to the rotating thread of the steering tie rod. Therefore, the position of the transmission head on the steering tie rod can be adjusted by rotating the transmission head, thereby adjusting the sensitivity of the two steering control levers in this application.

[0018] Preferably, the end of the steering tie rod is also provided with a positioning nut that engages with its thread, and the positioning nut abuts against the middle plate.

[0019] The positioning nut can abut and position the middle plate, preventing it from moving along the steering tie rod due to vibration during use.

[0020] Preferably, the steering lever includes a first steering lever and a second steering lever; a rotating shaft is mounted on the lever bracket, and the two ends of the rotating shaft are connected to the first steering lever and the second steering lever, respectively.

[0021] This allows the first steering lever to rotate, which in turn rotates the shaft and drives the second steering lever to rotate as well.

[0022] Preferably, the joystick bracket includes a horizontal plate and a vertical plate, with the rotating shaft passing through the vertical plate; the horizontal plate has several mounting holes.

[0023] The horizontal and vertical plates are integrally molded to form an L-shaped plate. Mounting holes on the horizontal plate facilitate the installation of the control stick bracket onto relevant equipment, such as the frame of an amphibious special vehicle.

[0024] Preferably, the connector includes a connector head and an L-shaped connecting piece. The connector head is fixedly disposed at the end of the steering tie rod. A connecting shaft is disposed at the end of the connector head away from the steering tie rod. One end of the L-shaped connecting piece is rotatably connected to the connecting shaft, and the other end is fixedly connected to the lateral control lever.

[0025] The L-shaped connecting piece has a second through hole and a third through hole at each end. The connecting shaft passes through the second through hole and is threaded into the connecting nut, allowing the connecting shaft to rotate freely within the second through hole. A second end hole is provided on the horizontal control lever. A bolt passes through the third through hole and is threaded into the second end hole, thereby fixing the L-shaped connecting piece to the horizontal control lever.

[0026] Preferably, a ball joint is provided at the end of the connector away from the steering tie rod, and a universal ball joint that mates with the ball joint is provided on the connecting shaft.

[0027] The swivel joint can rotate freely within the ball joint seat, allowing the force of the steering tie rod to be better transmitted to the tie rod through the cooperation between the swivel joint and the ball joint seat.

[0028] Preferably, the connecting shaft passes through the L-shaped connecting piece and is threaded into the connecting nut.

[0029] The above structure enables a rotatable connection between the L-shaped connecting piece and the connector.

[0030] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by pulling the steering control lever, causes the steering control lever to swing around the rotation axis, thereby driving the steering control lever to swing around the rotation axis. The swinging of the steering control lever causes the steering tie rod to move back and forth, and the back and forth movement of the steering tie rod causes the horizontal control lever to swing back and forth, thereby realizing the swinging of the steering nozzle around the nozzle body, thus realizing steering control. All the structures are implemented using a purely mechanical structure, which has the characteristics of simple structure, strong operability and stability, and can improve service life.

[0043] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0044] Example 1: Refer to Figures 1 to 7 As shown, a novel water propulsion and steering control device includes: a steering control lever 1 that rotates around a fulcrum, a steering nozzle 3 that is rotatably mounted on a spray pump body 2, and a horizontal control lever 31 connected to the steering nozzle 3; the steering control lever 1 and the horizontal control lever 31 are connected by a transmission assembly 4.

[0045] During operation, by pulling the steering control lever 1, the steering control lever 1 swings forward or backward around the fulcrum.

All structures are implemented using pure mechanical structures, which have the characteristics of simple structure, strong operability and stability, and can improve service life.

[0046] In one embodiment, a joystick support 5 is also included, on which a rotating shaft 13 is rotatably mounted; the steering joystick 1 is fixedly connected to the rotating shaft 13. When the steering joystick 1 is pulled, the steering joystick 1 can rotate around the steering shaft 13, thereby realizing the swinging of the steering joystick 1.

[0047] Specifically, the joystick support 5 includes a horizontal plate 51 and a vertical plate 52, with a rotating shaft 13 passing through the vertical plate 52; several mounting holes 53 are provided through the horizontal plate 51.

The swing of the steering control lever 12 drives the steering tie rod 41 to move back and forth. The back and forth movement of the steering tie rod 41 drives the horizontal control lever 31 to swing back and forth, thereby realizing the swing of the steering nozzle 3 around the nozzle body 2, thus realizing steering control.
