Description

Technical Field

[0001] This utility model relates to the field of sightseeing vehicle technology, and in particular to a zoo sightseeing vehicle using a connected trailer. Background Technology

[0002] With the development of modern tourism, zoos, as important venues integrating science education and leisure, are receiving increasing attention for the convenience, safety, and experience of their visitor systems. Traditional zoo tours mainly fall into two categories: walking tours and conventional electric trams. While walking tours allow for close observation of animals, they are physically demanding and difficult to cover the entire area of ​​a large zoo. While existing electric trams can reduce physical exertion, they generally have the following shortcomings:

[0003] 1. Traditional electric vehicles need to carry their own power source, battery, and drive axle. They are heavy and have a long wheelbase, making them difficult to maneuver on narrow, slippery, or uneven roads. They are prone to getting stuck in mud or becoming stuck, increasing operational risks and maintenance costs.

[0004] 2. Electric sightseeing vehicles require large-capacity power batteries and drive systems, resulting in high purchase and maintenance costs. During the off-season, vehicle utilization is low, yet regular charging and maintenance are still necessary, leading to persistently high operating costs. Furthermore, the repetitive cycle of individual electric vehicles often results in situations where passengers are waiting for vehicles or vice versa, hindering flexible scheduling based on real-time passenger flow and limiting overall operational efficiency.

[0005] 3. Most existing sightseeing vehicles are fixed structures, which cannot provide tourists with a good sightseeing view in open areas; if a temporary elevation device is added when parking, there are problems such as insufficient stability and cumbersome operation, which can easily cause safety hazards.

[0006] To address the aforementioned shortcomings, the industry has proposed improvement solutions such as liftable cabins and split-type towing vehicles. However, most of these solutions are complex in structure, expensive, or require large-scale modifications to park roads, making them difficult to promote on a large scale. Therefore, there is an urgent need for a new type of zoo tour vehicle that is low-cost, highly adaptable, offers adjustable visibility, and is safe and reliable, in order to solve many of the pain points of traditional tour methods. Utility Model Content

[0007] In order to overcome the shortcomings of the prior art, this utility model discloses a zoo tour vehicle that uses a connected trailer.

[0008] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0009] A zoo tour vehicle employing a coupled trailer includes:

[0010] The vehicle chassis adopts a fully trailer structure; the vehicle chassis is towed by a trailer.

[0011] The lift-up passenger cabin is installed on the vehicle chassis; when parked, the lift-up passenger cabin can be raised to provide tourists with a better sightseeing view;

[0012] The liftable passenger compartment includes:

[0013] The base plate is placed on the vehicle chassis;

[0014] The ceiling is located above the base plate;

[0015] Four lifting mechanisms are securely connected between the four corners of the base plate and the ceiling;

[0016] The lifting mechanism includes:

[0017] Hollow columns, with their bottoms securely connected to the base plate and their tops securely connected to the ceiling;

[0018] The lead screw is inserted into the hollow column;

[0019] The nut is fastened to the bottom of the hollow column and connected to the threaded screw.

[0020] A drive motor is mounted on the base plate; the output end of the drive motor is connected to a lead screw drive.

[0021] Preferably, the vehicle chassis is provided with side walls, and transparent windows are provided on all four sides of the side walls; a door is provided on one side of the side walls; when the liftable passenger compartment is in its lowest position, the bottom of the roof is in contact with the top of the side walls.

[0022] Preferably, a ladder is installed on the vehicle chassis at the position corresponding to the door.

[0023] Preferably, a sealing strip is provided at the top of the four sides of the compartment wall.

[0024] Preferably, an air conditioner is installed on the roof; a mobile power supply or generator is installed on the trailer to supply power to the air conditioner and the lifting mechanism.

[0025] Preferably, a guardrail is provided between two connected hollow columns.

[0026] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0027] (1) The structure of this utility model completely breaks free from the constraints of traditional electric vehicles that must have their own power system: the vehicle chassis only serves as a load-bearing platform, and can be parked after being towed into place by an external trailer. There is no need to configure an engine, battery pack and corresponding heat dissipation and control system. The structure is greatly simplified, and the manufacturing cost and subsequent maintenance cost decrease simultaneously. Especially in the off-season when there are few tourists, the entire fleet can be parked in one place with almost no maintenance required, resulting in significant operating cost advantages. The lifting function of the passenger cabin provides tourists with a wider and more comfortable sightseeing view.

[0028] (2) The vehicle chassis of this utility model can be unhooked and parked after being towed to the sightseeing area by a trailer. The trailer can immediately return to pick up the next batch of tourists, realizing the cycle mode of "vehicles waiting for people" rather than "people waiting for vehicles", which significantly shortens the queuing time of tourists and improves the turnover rate of single vehicles. At the same time, the chassis does not need to consider power performance and can be specially designed for the complex terrain of the zoo with low ground pressure, and its passability is better than that of traditional electric sightseeing vehicles.

[0029] (3) The present invention further forms a complete enclosed space by lowering the four sides of the compartment walls and the roof. The sealing strips around the top of the compartment walls are tightly attached to the bottom of the roof, effectively blocking wind, rain and odors from entering the compartment.

[0038] Example 1:

[0039] Combined with appendix Figures 1-4 A zoo tour vehicle employing a trailer-mounted design includes a vehicle chassis 1 and a liftable passenger cabin. The vehicle chassis 1 features a fully trailer-mounted structure and is towed by a trailer, a design that offers unique advantages for zoo tour vehicles.

[0040] A liftable passenger compartment is installed on the vehicle chassis 1. Its main function is to provide tourists with a better view when the vehicle is parked by raising the passenger compartment. Specifically, the liftable passenger compartment consists of a floor 2, a roof 3, and lifting mechanisms. The floor 2 is fixed to the vehicle chassis 1, and the roof 3 is installed above the floor 2, forming the basic structure of the passenger compartment. A lifting mechanism is installed between each of the four corners of the floor 2 and the roof 3. Its function is not only to support the roof 3, but also to drive the entire passenger compartment to rise and fall.

[0041] As attached Figure 4 As shown, the lifting mechanism is the core component of the passenger cabin's lifting function, mainly composed of a hollow column 4, a lead screw 5, and a nut 6. The bottom end of the hollow column 4 is fixedly connected to the base plate 2, and the top end is fixedly connected to the roof 3, forming a stable support structure. The lead screw 5 is housed inside the hollow column 4, its bottom end rotatably connected to the vehicle chassis 1, forming a pivot point. A nut 6 is also fixedly installed at the bottom end of the hollow column 4, and the nut 6 and the lead screw 5 are mechanically transmitted through a threaded connection. A drive motor 12 is installed on the base plate 2, its output end directly connected to the lead screw 5. By controlling the forward and reverse rotation of the drive motor 12, the rotation direction of the lead screw 5 can be adjusted, thereby driving the entire passenger cabin to complete the raising or lowering action. This design of the lifting mechanism ensures a smooth and reliable lifting process for the passenger cabin, providing a comfortable riding experience for passengers.

[0042] In addition, guardrails 11 are installed between two adjacent hollow pillars 4. When the passenger cabin is raised to a higher position, passengers can obtain safety through the guardrails 11 to prevent accidents. This design fully considers the safety needs of passengers, ensuring that they can enjoy the scenery with peace of mind during sightseeing.

[0043] The practicality and advantages of this design are mainly reflected in the following aspects: Firstly, since the vehicle chassis 1 is entirely towed by a trailer, there is no need for an additional drive mechanism, thus effectively reducing operating costs. Especially during the off-season when there are fewer tourists, the vehicle can be parked for extended periods with almost no maintenance required. Secondly, compared to many existing electric sightseeing vehicles, this design is better able to adapt to complex terrain. After the trailer tows the vehicle chassis 1 to the sightseeing area, the chassis 1 can be parked, while the trailer can return to tow the next sightseeing vehicle. This not only provides tourists with ample time for sightseeing but also avoids long waiting times for subsequent groups of tourists, improving the efficiency of the sightseeing vehicle's use.

[0044] Example 2:

[0045] Combined with appendix Figures 1-3 A zoo tour vehicle employing a connected trailer differs from Embodiment 1 in that, based on Embodiment 1, additional side walls 7 are added around the vehicle chassis 1. All four sides of the side walls 7 are equipped with transparent windows, allowing visitors to enjoy the scenery along the way; additionally, a door 8 is located on one side of the side walls 7 for easy boarding and alighting. When the lift-type passenger compartment is lowered to its lowest position, the bottom of the roof 3 fits tightly against the top of the side walls 7, forming a sealed structure. To further ensure a tight seal, sealing strips are installed around the top of the side walls 7; this design effectively protects the safety of visitors during operation.

[0046] In addition, a staircase 9 has been added to the corresponding position of the door 8 on the vehicle chassis 1, facilitating easy access for visitors to the passenger cabin. An air conditioner 10 is also installed on the roof 3, while a mobile power source or generator is mounted on the trailer to provide stable power to the air conditioner 10 and the lifting mechanism. When the passenger cabin is sealed, the air conditioner 10 can regulate the interior temperature, creating a more comfortable travel environment for visitors. These improvements ensure that the zoo tour vehicle meets visitors' sightseeing needs while also prioritizing safety and comfort, making it a transportation tool with broad application prospects.

[0047] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
