Technical Field

[0001] This application relates to the field of vehicle testing technology, and more specifically, to an electric remote-controlled multi-functional snow surface maintenance device for indoor ice and snow vehicle testing grounds. Background Technology

[0002] Indoor ice and snow proving grounds are a new type of facility for off-season winter testing in the automotive industry. They can create various icy and snowy road conditions, unrestricted by season or location. To ensure the accuracy, repeatability, and safety of the tests, the smoothness, compaction, and cleanliness (free from oil and other contaminants) of the snow surface are subject to extremely high requirements. Currently, the maintenance of indoor ice and snow proving grounds largely borrows from the snow grooming equipment or manual methods used in outdoor ski resorts. The main problems are as follows:

[0003] Limited functionality: Existing snow groomers can only perform leveling and compaction functions, and cannot efficiently remove snow contaminated by vehicle testing (such as snow stained with engine oil or brake pad powder), nor can they perform fixed-point and quantitative snow replenishment.

[0004] Pollution issues: Traditional equipment is mostly driven by internal combustion engines, which will produce a lot of exhaust gas in a closed indoor environment, seriously polluting the air and ice and snow surfaces, and affecting the testing environment.

[0005] Poor adaptability: Large outdoor snow groomers are bulky and inconvenient to operate in limited indoor spaces, resulting in poor flexibility.

[0006] Inefficient: Relying on manual snow removal and replenishment operations is inefficient, costly, and makes it difficult to ensure the uniformity of snow surface quality.

Detailed Implementation

[0031] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0032] The present application will be further described in detail below with reference to the embodiments.

[0033] Figure 1 This is a schematic diagram of the structure of an electrically controlled multi-functional snow surface maintenance device for an indoor ice and snow vehicle proving ground, provided in an embodiment of this application. The device includes: a main body 1, a walking system 2, an electric drive system (not shown), a snow removal and snow collection device 3, a snow storage and snow spraying device 4, and a compaction and leveling device 5. This electrically controlled multi-functional snow surface maintenance device adopts a compact design, and its overall width and length are adapted to the passage and space limitations of the indoor proving ground.

[0034] The main body of the equipment 1 adopts a compact steel structure frame to adapt to the limited indoor space.

[0035] The walking system 2 is a tracked walking mechanism to support and drive the main body of the equipment 1. The tracked walking mechanism prevents slipping on snow. The walking system has one track on each side, driven by an independent drive motor, providing the equipment with strong snow adhesion and passability, and enabling flexible steering.

[0036] The electric drive system is used to drive the walking system 2. The electric drive system includes a large-capacity battery pack and an electronic control unit, which provides power to all motors and components, achieving zero exhaust emissions and meeting indoor environmental protection requirements.

[0037] The snow removal and snow collection device 3 includes a front shovel located at the front end of the main body of the device; the front shovel includes a snow shovel 33 and an electric push rod 32; the electric push rod 32 controls the raising and lowering of the snow shovel 33. The front shovel can be used to shovel and collect two types of snow: one is contaminated snow that needs to be removed; the other is clean natural snow stored in the snow storage area of ​​the ski resort, and the snow in the snow shovel 33 is poured into the snow storage chamber 41.

[0038] The snow storage and spraying device 4 includes a snow storage chamber 41 (located in the middle of the main body 1) and a snow conveying mechanism within the snow storage chamber 41. The snow conveying mechanism is used to transport snow from the snow storage chamber 41 to the snow spray nozzles 44. The snow spray nozzles 44 face both sides of the road. Specifically, the top of the snow storage chamber 41 is provided with a snow inlet, which connects to the guide groove of the front shovel to receive the snow fed in by the front shovel. The snow storage chamber 41 is provided with a snow conveying mechanism, including a screw conveyor 42 and a scraper conveyor 43, for transporting snow from the front to the rear of the snow storage chamber 41 and discharging it through the snow spray nozzles 44. Figure 1 In the middle section, the screw conveyor 42 mainly consists of screw blades (auger), a rotating shaft, a housing (cover), and a drive device (such as a hydraulic motor or electric motor). The screw blades are fixed on a central rotating shaft and rotate inside the housing to break and transport snow. The scraper conveyor 43 mainly includes a traction chain (or belt), scrapers, guide rails, head and tail sprockets (or rollers), and a drive device. The scrapers are fixed on the traction chain at certain intervals, and the drive device drives the sprockets to rotate, thereby tractioning the chain and the scrapers on it to move within the enclosed trough. The scrapers scrape up the snow accumulated at the bottom of the trough and carry it forward, unloading it when it reaches the snow spray nozzle 44.

[0039] The compaction and leveling device 5 includes a snow-pressing roller 51 and a snow-leveling frame 52 located at the rear of the main body of the equipment. The snow-pressing roller 51 and snow-leveling frame 52 compact and level the snow. The snow-leveling frame 52 is located behind the snow-pressing roller 51, and both the snow-pressing roller 51 and snow-leveling frame 52 are controlled by independent lifting mechanisms, enabling independent lifting. The snow-pressing roller 51 is used to compact and level newly added snow. The snow-leveling frame 52 follows immediately after the snow-pressing roller 51, performing final smoothing of the compacted snow surface to achieve the required firmness and smoothness for automotive testing.

[0040] The battery pack 7 is used to power the electric drive system, electric push rod 32, screw conveyor 42 and scraper conveyor 43 actuators and lifting mechanism, so that all electrical devices of the entire equipment are powered by the battery pack 7, achieving environmental protection and zero pollution.

[0041] The equipment also includes a wireless remote control system; this system controls the operation of the electrically powered, multi-functional snow maintenance equipment via wireless signals. For example, when the equipment reaches an area requiring snow replenishment, the operator activates the snow replenishment function via the wireless remote control system, discharging snow evenly from the snow spray nozzle 44 at the rear of the snow storage chamber 41, and then compacting it through the compaction and leveling device 5, achieving targeted and quantitative snow replenishment. Through the wireless remote control system, the operator can remotely control all actions of the equipment, including movement, steering, and the start and stop of various operational functions.

[0042] The following specific example illustrates the usage of the device:

[0043] like Figure 1 As shown, a tracked walking mechanism 2 is installed on the lower part of the main body 1 of the equipment, which is driven by a built-in electric drive system. The power comes from the battery pack inside the equipment. The operator sends signals through a handheld remote control (i.e., the terminal of the wireless remote control system), which are received by the antenna 6 to control the movement, steering, and completion of various tasks of the equipment.

[0044] During operation, the operator first controls the electric push rod 32 to lower the snow shovel 33. The equipment moves forward, and the snow shovel 33 scoops up the snow on the ground (whether it is contaminated snow to be cleared or clean snow to be collected), and pours it into the snow storage bin 41 by lifting the snow shovel 33. If it is a clearing operation, the equipment transports the contaminated snow to the dumping point, and discharges the contaminated snow from the snow spray nozzle 44 through the screw conveyor 42 and scraper conveyor 43. If it is a snow replenishment operation, the equipment loads clean snow and travels to the target area, and the screw conveyor 42 and scraper conveyor 43 are remotely activated to spray the clean snow evenly from the snow spray nozzle 44.

[0045] After replenishing the snow, the equipment lowers the snow-pressing roller 51 at the rear to compact the snow. Then, the snow leveling frame 52 scrapes the compacted snow layer to form a solid and flat test snow surface.

[0046] Compared with the prior art, the device provided in this embodiment has the following advantages:

[0047] 1. Highly integrated functions: One device simultaneously solves five core needs: snow removal, snow transport, snow replenishment, snow compaction, and snow leveling, significantly improving the maintenance efficiency of indoor snow surfaces.

[0048] 2. Environmentally friendly and pollution-free: Pure electric drive completely eliminates indoor exhaust pollution and protects the testing environment.

[0049] 3. Flexible and precise operation: The remote control operation combined with the compact tracked chassis allows the equipment to move freely in indoor spaces; it can achieve precise spot snow replenishment and fine leveling operations.

[0050] 4. Highly targeted: Specifically designed to address the three core pain points of indoor automotive testing grounds: "need to replace contaminated snow", "need to replenish stored snow", and "need to achieve high-precision leveling and compaction", making it highly practical.

[0051] 5. High degree of automation: It reduces a lot of manual work, lowers labor costs and reduces inconsistencies in human operation.

[0052] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

[0053] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
