Description

Technical Field

[0001] This utility model relates to the field of sightseeing vehicle roof adjustment technology, and in particular to a lifting roof for an all-terrain sightseeing vehicle. Background Technology

[0002] In the field of all-terrain sightseeing vehicle canopy adjustment devices, traditional structures mostly adopt fixed canopies or single-column electric push rod lifting solutions. Such designs have significant limitations: fixed canopies cannot be height-adjusted according to the desired view, while electric lifting mechanisms are prone to tilting and jamming on rough terrain due to uneven force on both sides, and the motor system has a high failure rate in damp outdoor environments. More importantly, existing technologies generally rely on electronic sensors for limit protection, posing a safety risk of accidental canopy collapse in the event of a sudden pressure release in the hydraulic system or circuit failure. Utility Model Content

[0003] This invention provides a lifting canopy for all-terrain sightseeing vehicles, aiming to address the shortcomings of existing technologies mentioned in the background section. This invention, through a mechanically coordinated design of double-layered columns and a two-way synchronous valve, ensures that the canopy can achieve horizontal synchronous lifting in multi-slope terrain; combined with a hydraulically operated three-position mechanism and a dual protection mechanism of mechanical limits, it completely solves the problems of poor adjustment accuracy and insufficient safety of traditional devices.

[0004] This utility model provides the following technical solution to achieve the above objectives:

[0005] A retractable canopy for an all-terrain sightseeing vehicle includes a canopy with multiple sets of inner lifting columns connected downwards on both sides of the canopy. The bottom of each inner lifting column has a protrusion hinged to the piston rod of a hydraulic cylinder. The hydraulic cylinder and the inner lifting columns are housed within outer lifting columns, which are slidably connected. A mechanical limiting mechanism is provided within the outer lifting columns. The canopy also includes a hydraulic oil tank connected via an oil circuit to a hydraulic control mechanism. The hydraulic control mechanism is connected via an oil circuit to a bidirectional upward synchronous valve and a bidirectional downward synchronous valve, which are respectively connected via oil circuits to the hydraulic cylinder.

[0006] In the aforementioned all-terrain sightseeing vehicle's lifting canopy, the hydraulic control mechanism has three control positions: UP, STOP, and DOWN.

[0007] In the aforementioned all-terrain sightseeing vehicle lifting canopy, the mechanical limiting mechanism includes a mechanical upper limit block and a mechanical lower limit block installed on the inner wall of the outer lifting column. The mechanical upper limit block and the mechanical lower limit block are respectively installed above and below the protrusion installed at the bottom of the inner lifting column.

[0008] In the aforementioned all-terrain sightseeing vehicle lifting canopy, the canopy is a full-frame canopy.

[0009] In the aforementioned all-terrain sightseeing vehicle lifting canopy, the inner lifting column and the outer lifting column are slidably connected by guide rails and guide rail grooves.

[0010] In the aforementioned all-terrain sightseeing vehicle lifting canopy, the top of the inner lifting column is connected to the canopy via a flange.

[0011] In the aforementioned all-terrain sightseeing vehicle's lifting canopy, the hydraulic oil tank is connected to the hydraulic power-assisted pump's oil circuit.

[0012] Beneficial effects

[0013] This utility model is achieved through a full-frame roof assembly, double-layer lifting columns, a hydraulic operating mechanism (UP / STOP / DOWN), a two-way synchronous valve group (rising / falling), a hydraulic cylinder, and a mechanical limit mechanism. Compared with the prior art, it has the following advantages:

[0014] 1. The two-way synchronous valve group is integrated into the lifting oil circuit. Through hydraulic balance control, the problem of roof tilting in multi-slope terrain is completely solved. Even if the vehicle is on a rough road, the roof can still be kept level.

[0015] 2. The mechanical limit mechanism and hydraulic control gear form a double interlock protection, which can automatically lock at the lifting end in the event of sudden pressure loss or circuit failure in the hydraulic system, thus completely avoiding the risk of sudden pressure loss.

[0016] 3. The sealed hydraulic system integrates a high-efficiency oil filter, and with the rainproof and sunproof structure of the full-frame roof, it significantly improves the continuous operation capability of the device in humid, dusty and high and low temperature environments.

[0017] Therefore, this utility model integrates lifting stability, environmental adaptability and passive protection functions into a compact hydraulic system, which can provide reliable all-weather protection for all-terrain sightseeing vehicles. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1. A retractable canopy for an all-terrain sightseeing vehicle, the structure of which is as follows: Figure 1-3 As shown, the system includes a ceiling 1, with multiple sets of inner lifting columns 13 connected downwards on the left and right sides of the ceiling 1. The bottom of the inner lifting columns 13 has a protrusion that is hinged to the piston rod of the hydraulic cylinder 2. The hydraulic cylinder 2 and the inner lifting columns 13 are located in the outer lifting columns 12, and the inner lifting columns 13 and the outer lifting columns 12 are slidably connected. The outer lifting columns 12 are equipped with a mechanical limiting mechanism. The system also includes a hydraulic oil tank 14, which is connected to a hydraulic control mechanism 8 via an oil circuit. The hydraulic control mechanism 8 is connected to a rising bidirectional synchronous valve 6 and a descending bidirectional synchronous valve 7 via an oil circuit. The rising bidirectional synchronous valve 6 and the descending bidirectional synchronous valve 7 are respectively connected to the hydraulic cylinder 2 via oil circuits.

[0024] The hydraulic control mechanism 8 is equipped with three control positions: UP, STOP, and DOWN.

[0025] The mechanical limiting mechanism includes an upper mechanical limit block 10 and a lower mechanical limit block 11 disposed on the inner wall of the outer lifting column 12. The upper mechanical limit block 10 and the lower mechanical limit block 11 are respectively disposed above and below the protrusion disposed at the bottom of the inner lifting column 13. When the protrusion of the inner lifting column 13 rises to the upper mechanical limit block 10, the ceiling immediately stops rising; when descending, the protrusion touches the lower mechanical limit block 11, achieving mechanical locking, thereby realizing limit protection.

[0026] The canopy 1 is a full-frame canopy. The full-frame canopy with an aluminum alloy frame is strong, easy to install, and integrates sun protection and rain protection functions, making it suitable for the all-weather operation needs of all-terrain sightseeing vehicles.

[0027] The inner lifting column 13 and the outer lifting column 12 are slidably connected by guide rails and guide rail grooves. The guide rails guide the inner lifting column 13.

[0028] The top of the inner lifting column 13 is connected to the roof 1 via a flange.

[0029] This retractable canopy is used on all-terrain sightseeing vehicles, so the bottom of the outer retractable column 12 is mounted on the vehicle frame. The hydraulic oil tank 14's oil circuit is also connected to the hydraulic steering gear 17 and the hydraulic power steering pump 9 of the engine 15. (See reference...) Figure 1 .

[0030] When the above-mentioned lifting roof is implemented, the hydraulic operation process is as follows: When the operator switches the hydraulic control mechanism 8 gear through the hydraulic steering gear 17: (1) Lifting operation (gear adjusted to UP): The hydraulic oil (purified by the oil filter (model RFA-100*20L)) is pressurized and delivered by the hydraulic power pump 9. The high pressure oil enters the rod chamber of the hydraulic cylinder 2 through the lifting two-way synchronous valve 6, driving the piston rod to extend at a uniform speed, and the roof 1 rises smoothly; (2) Stopping operation (gear adjusted to STOP): The oil circuits of the lifting two-way synchronous valve 6 and the lowering two-way synchronous valve 7 are closed simultaneously, the oil pressure of the hydraulic cylinder 2 is locked instantaneously, and the movement of the roof 1 stops immediately; (3) Lowering operation (gear adjusted to DOWN): The lowering two-way synchronous valve 7 opens the return oil channel, and the oil in the rod chamber of the hydraulic cylinder 2 flows slowly back to the hydraulic oil tank 10 through the return oil pipeline 3. The hydraulic oil tank 10 is connected to the hydraulic power pump 9 on the engine 15 through the oil inlet pipeline 5, and the roof 1 descends slowly under its own weight.
