Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle protection appliances, and particularly relates to a vehicle protection device. Background Art

[0002] With the improvement of residents' living standards, cars have gradually become popular. However, during the use of vehicles, since vehicles generally need to be exposed to the external environment for a long time, they may encounter various adverse weather conditions, such as rain, snow, hail, etc. If the vehicle is not well protected, it may result in significant property losses.

[0003] However, current vehicle protection devices generally adopt forms such as car wraps or car covers. Not only are they cumbersome to operate manually each time, but their protection functions are also limited. They can only perform simple functions such as dust prevention and sun protection, and are insufficient in protecting against adverse weather conditions such as rain, snow, and hail. Moreover, vehicle protection devices that can protect against rain, snow, hail, etc. generally have a large volume and may be restricted in some scenarios, such as being restricted by not changing the nature of the garage use or being restricted by the electricity supply in the garage, etc., and are inconvenient to use.

[0064] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present utility model. However, those skilled in the art should understand that the present utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the present utility model.

[0065] In order to illustrate the technical solutions described in the present utility model, the following will be described through specific embodiments.

[0066] As Figure 1 shown, the vehicle protection device provided by the embodiment of the present utility model includes: a protection top plate 1, a contraction device 2, a surrounding protection layer 3, a sealing airbag 4, a bottom protection layer 5, and a ground rail 6.

[0067] Among them, the protection top plate 1 is fixed through a fixing bracket, the contraction device 2 is arranged on the protection top plate 1, the surrounding protection layer 3 is arranged on the protection top plate 1 and is contracted or unfolded through the contraction rope in the contraction device 2, the sealing airbag 4 is arranged at the bottom of the surrounding protection layer 3, the bottom protection layer 5 is used to cover the parking space, and the ground rail 6 is arranged around the bottom protection layer 5 and is used for cooperating and connecting with the sealing airbag 4.

[0068] In this embodiment, if the application scenario of the vehicle protection device is an underground garage, the protection top plate 1 can be fixed to the top of the underground garage through the fixing bracket. If the application scenario of the vehicle protection device is other situations, the protection top plate 1 can be fixed to other convenient positions through the fixing bracket. Thus, the contraction device 2, the surrounding protection layer 3, and the sealing airbag 4 are fixed without causing additional impacts.

[0069] Exemplarily, the surrounding protection layer 3 can be a waterproof material such as Polyvinyl Chiloride (PVC), and the contraction rope led out from the contraction device 2 can form the support framework of the surrounding protection layer 3. As Figure 2 shown, when controlling the contraction of the contraction rope in the contraction device 2, the surrounding protection layer 3 can be folded as shown by the dotted line in Figure 2 , and when controlling the unfolding of the contraction rope in the contraction device 2, the surrounding protection layer 3 can be unfolded as shown by the solid line in Figure 2 , and the sealing airbag 4 is arranged at the bottom of the surrounding protection layer 3.

[0070] Optionally, the vehicle protection device can further include a water level detector, and the sealing airbag 4 can include an airbag body and a gas generator.

[0071] Among them, the water level detector can be arranged on the surrounding protective layer 3 and is used to send a trigger signal to the gas generator after the detected water level reaches the set water level. The airbag body can be arranged at the bottom of the surrounding protective layer 3, the gas generator can be arranged on the surrounding protective layer 3, and the gas generator and the airbag body can be connected through an air path. The gas generator generates gas according to the trigger signal to inflate the airbag body.

[0072] Exemplarily, the airbag body and the gas generator connected through an air path in this embodiment are similar to an airbag. The gas generator can contain solid fuel, such as sodium azide (NaN3) or ammonium nitrate (NH4NO3). After the water level detector sends a trigger signal to the gas generator, the solid fuel in the gas generator can be rapidly decomposed under the action of an igniter to generate a large amount of nitrogen gas to fill the airbag body. After the gas generator is used, the gas generator can be replaced manually or automatically.

[0073] In this embodiment, by arranging the water level detector and the gas generator, automatic control of the sealed airbag 4 can be realized.

[0074] As Figure 3 shown, the ground rail 6 can correspond to the parking space line on the parking space. The bottom protective layer 5 can be slightly larger than the parking space line on the parking space. The ground rail 6 can be arranged on the bottom protective layer 5 through a waterproof connection material such as waterproof glue. The bottom protective layer 5 can also adopt waterproof materials such as PVC to form a sealed cabin structure that can prevent the vehicle from being flooded through the bottom protective layer 5 and the surrounding protective layer 3. The cross-sectional view of the ground rail 6 is as Figure 4 shown. By adopting Figure 4 the ground rail 6 with a small external opening and a large internal opening as shown, when the sealed airbag 4 is in a contracted state, it can be placed into the ground rail 6, and when needed, the sealed airbag 4 can be inflated to form a sealed structure with the ground rail 6, so as to ensure that the bottom protective layer 5 and the surrounding protective layer 3 can form a sealed cabin structure, and further realize the function of preventing the vehicle from being flooded.

[0075] Combined with Figures 1 to 4 , the vehicle protection device provided in this embodiment can make the surrounding protective layer 3 contract through the contraction device 2 when not in use, and when in use, control the surrounding protective layer 3 to unfold through the contraction device 2, and place the sealed airbag 4 at the bottom of the surrounding protective layer 3 into the groove of the ground rail 6, so that after detecting that the water level reaches a certain height, the sealed airbag 4 can be inflated to expand and seal the groove of the ground rail 6.

[0076] The vehicle protection device according to the embodiment of the present utility model is composed of a protection top plate 1, a contraction device 2, a surrounding protection layer 3, a sealing airbag 4, a bottom protection layer 5 and a ground rail 6. On the one hand, the protection top plate 1 and the contraction device 2, the surrounding protection layer 3 and the sealing airbag 4 on the protection top plate 1 can be fixed on the top of the garage or the vehicle through a fixing bracket, and do not involve too many electrical devices, meeting the limitations of not changing the use nature of the garage and the garage electricity consumption, etc. On the other hand, through the cooperation of the sealing airbag 4 and the ground rail 6, it can also better prevent the vehicle from being flooded and protect the property safety of residents.

[0077] Optionally, as Figure 5 shown, the contraction device 2 may include: a plurality of contraction ropes 21, a main disc spring assembly 22, a sub-disc spring assembly 23 and a control assembly 24.

[0078] Among them, a plurality of contraction ropes 21 penetrate the bottom and top of the surrounding protection layer 3, the main disc spring assembly 22 is connected to the contraction rope 21, the sub-disc spring assembly 23 is detachably connected to the main disc spring assembly 22, and the control assembly 24 is arranged on the sub-disc spring assembly 23 for controlling the separation or combination of the sub-disc spring assembly 23 and the main disc spring assembly 22.

[0079] In this embodiment, the contraction device 2 is mainly composed of a main disc spring assembly 22 and a sub-disc spring assembly 23. A plurality of contraction ropes 21 are connected to one end of the main disc spring assembly 22, and the sub-disc spring assembly 23 is detachably connected to the main disc spring assembly 22. Thus, when in need of use, the sub-disc spring assembly 23 is controlled by the control assembly 24 to be separated from the main disc spring assembly 22, so that the force of the main disc spring assembly 22 is released, and then the contraction ropes 21 connected to the main disc spring assembly 22 are unfolded to drive the surrounding protection layer 3 to unfold. When not in need of use, the sub-disc spring assembly 23 stores energy, and the sub-disc spring assembly 23 is controlled by the control assembly 24 to be combined with the main disc spring assembly 22, so that the energy stored in the sub-disc spring assembly 23 is transmitted to the main disc spring assembly 22 and drives the surrounding protection layer 3 to contract through the contraction ropes 21. Thus, the function of controlling the contraction or unfolding of the surrounding protection layer 3 is realized through the contraction device 2.

[0080] Optionally, in combination with Figure 6 and Figure 7 shown, the main disc spring assembly 22 may include: a bottom plate 221, a main shaft 222, a main disc spring 223, a main top plate 224.

[0081] Among them, the bottom plate 221 is arranged on the protective top plate 1 and has a through hole 2211 for accommodating the output end of the main shaft 222; the main shaft 222 is arranged on the bottom plate 221, and the output end of the main shaft 222 is located in the through hole 2211 of the bottom plate 221; the main disc spring 223 is located on the bottom plate 221, one end of the main disc spring 223 is fixed on the main shaft 222, and the other end of the main disc spring 223 is fixed on the fixing rod 2212 on one side of the bottom plate 221; the main top plate 224 is located on the main disc spring 223 and has a through hole 2241 for accommodating the joint end of the main shaft 222.

[0082] Optionally, in combination with Figures 8 to 10 As shown, the auxiliary disc spring assembly 23 may include: an auxiliary disc spring 231, an auxiliary shaft 232, and an auxiliary top plate 233.

[0083] Among them, the auxiliary disc spring 231 is located on the main top plate 224, one end of the auxiliary disc spring 231 is fixed on the auxiliary shaft 232, and the other end of the auxiliary disc spring 231 is arranged between the fixing rod 2242 on one side of the main top plate 224 and the control assembly 24; one end of the auxiliary shaft 232 is used to separate or combine with the joint end of the main shaft 222 under the control of the control assembly 24, and the other end of the auxiliary shaft 232 protrudes upward through the through hole on the auxiliary top plate 233; the auxiliary top plate 233 is located on the auxiliary disc spring 231.

[0084] As Figure 8 shown, there may also be a slot 2243 beside the fixing rod 2242 on one side of the main top plate 224, and the control assembly 24 may be arranged in the slot 2243 of the main top plate 224, so as to limit the other end of the auxiliary disc spring 231 between the fixing rod 2242 on one side of the main top plate 224 and the control assembly 24, and further realize the control of the auxiliary disc spring assembly 23 and the main disc spring assembly 22 through the control assembly 24.

[0085] As Figure 9 and Figure 10 shown, in order to facilitate the combination of one end of the auxiliary shaft 232 with the joint end of the main shaft 222, a mating groove 2321 matching the joint end of the main shaft 222 may be arranged on the auxiliary shaft 232. In order to avoid wearing the joint end of the main shaft 222 during the rotation of the main shaft 222 and the auxiliary shaft 232 after the combination of the auxiliary shaft 232 and the joint end of the main shaft 222, a certain margin may be left for the setting position of the mating groove 2321 on the auxiliary shaft 232. As Figure 9 shown, the mating groove 2321 may be arranged at a certain position upward from the bottom of the auxiliary shaft 232.

[0086] It should be noted that Figure 7 、 Figure 9 、 Figure 10Only an example of the coupling end of the main shaft 222 and the mating groove 2321 on the auxiliary shaft 232 is shown. According to actual needs, the coupling end of the main shaft 222 and the mating groove 2321 on the auxiliary shaft 232 can also be designed into other shapes, such as a "cross" shape, etc. This embodiment does not limit this.

[0087] Optionally, as shown in combination Figures 9 to 11 shown, the control assembly 24 may include: a coupling rod 241, a separation disc 242, a separation rod 243, a control cable winding disc 244, and a reset link 245. The other end of the auxiliary shaft 232 located above the auxiliary top plate 233 has a coupling hole 2322 and a separation hole 2323, and the separation hole 2323 is located above the coupling hole 2322.

[0088] Among them, the coupling rod 241 passes through the coupling hole 2322 and is fixed to the other end of the auxiliary shaft 232.

[0089] The separation disc 242 is sleeved on the other end of the auxiliary shaft 232, and a blocking portion 2421 is provided on the inner side of the separation disc 242 close to the auxiliary top plate 233. The longitudinal section of the end of the separation disc 242 away from the auxiliary top plate 233 is "V" shaped.

[0090] The separation rod 243 passes through the separation hole 2323 and is fixed to the other end of the auxiliary shaft 232, and the separation rod 243 is located above the separation disc 242.

[0091] A control cable 2441 is wound around the control cable winding disc 244, and the control cable winding disc 244 is connected to the separation disc 242 through a one-way movement control mechanism.

[0092] One end of the reset link 245 is movably connected to the main top plate 224 and is used to jointly limit the other end of the auxiliary disc spring 231 with the fixed rod 2242 on one side of the main top plate 224. The other end of the reset link 245 passes through the auxiliary top plate 233 and is fixed above the other end of the auxiliary shaft 232.

[0093] When controlling the separation of one end of the auxiliary shaft 232 from the coupling end of the main shaft 222, pull the control cable 2441, so that the control cable winding disc 244 drives the separation disc 242 to rotate through the one-way movement control mechanism. Through the rotation of the separation disc 242, the separation rod 243 moves upward from the bottom of the "V" shaped longitudinal section of the separation disc 242. Through the upward movement of the separation rod 243, the auxiliary shaft 232 is driven to move upward, realizing the separation of one end of the auxiliary shaft 232 from the coupling end of the main shaft 222. And through the upward movement of the auxiliary shaft 232, the coupling rod 241 moves upward to above the blocking portion 2421, realizing the coupling of the auxiliary shaft 232 and the separation disc 242.

[0094] When one end of the control secondary shaft 232 is combined with the combined end of the main shaft 222, the control pull rope 2441 is pulled again, so that the pull rope winding disc 244 drives the separation disc 242 to rotate through the one-way movement control mechanism. Through the rotation of the separation disc 242, the secondary shaft 232 is driven to rotate. Through the rotation of the secondary shaft 232, the other end of the secondary disc spring 231 moves from the fixed rod on one side of the main top plate 224 to one end of the reset link 245. Through the movement of the other end of the secondary disc spring 231, the other end of the reset link 245 is pressed down towards the other end of the secondary shaft 232, realizing the combination of one end of the secondary shaft 232 and the combined end of the main shaft 222.

[0095] Exemplarily, as Figures 12 to 15 shown, the separation disc 242 may have fixed ratchet teeth 2422, and the pull rope winding disc 244 may have movable ratchet teeth 2442, so that only one-way movement is possible between the pull rope winding disc 244 and the separation disc 242 through a one-way movement control mechanism such as a ratchet and pawl.

[0096] Exemplarily, a one-way movement control mechanism such as a ratchet and pawl may also be provided at the other end of the secondary shaft 232, so that when the pull rope winding disc 244 drives the separation disc 242 to rotate through the one-way movement control mechanism and then drives the secondary shaft 232 to rotate, the secondary shaft 232 will not reset when the control pull rope 2441 is released.

[0097] Using the contraction device 2 provided in this embodiment, the control pull rope 2441 can be wound around the pull rope winding disc 244. By pulling the control pull rope 2441, the pull rope winding disc 244 can drive the separation disc 242 to rotate through the one-way movement control mechanism. The separation rod 243 is initially located at the lowest point of the "V"-shaped longitudinal section on the separation disc 242. As the separation disc 242 rotates, the separation rod 243 is driven by the "V"-shaped longitudinal section on the separation disc 242 to move from the lowest point of the "V"-shaped longitudinal section to the highest point, so that the secondary shaft 232 is separated from the main shaft 222, the force of the main disc spring assembly 22 is released, and the surrounding protective layer 3 is driven to unfold. In the state where the secondary disc spring assembly 23 and the main disc spring assembly 22 are separated, pulling the control pull rope 2441 again can drive the pull rope winding disc 244, the separation disc 242, the secondary shaft 232 and the secondary disc spring 231 to rotate, so that the secondary disc spring 231 stores energy. When the control pull rope 2441 is pulled multiple times and the energy storage reaches the limit value of the reset link 245, the other end of the reset link 245 will be pressed down towards the other end of the secondary shaft 232, so that the secondary shaft 232 is re-combined with the main shaft 222, and the energy stored in the secondary disc spring 231 is transmitted to the main shaft 222, and then transmitted to the contraction rope 21 through the main disc spring 223. The surrounding protective layer 3 is driven to contract by the contraction rope 21, so that the contraction and unfolding of the surrounding protective layer 3 can be realized without too many electrical devices.

[0098] Optionally, as Figure 16and Figure 17 As shown in Figure 17 , the vehicle protection device may further include: a ground rail protection plate 7 and at least two positioning pins 8.

[0099] Among them, the ground rail protection plate 7 is at least arranged on one side of the ground rail 6 facing the vehicle entry and exit, and one end of the ground rail protection plate 7 is rotatably connected to the inner side of the ground rail 6, and the plate body 71 of the ground rail protection plate 7 covers above the ground rail 6.

[0100] At least two positioning pins 8 are arranged at the bottom of the surrounding protection layer 3 and are used to open the ground rail protection plate 7 when the surrounding protection layer 3 is unfolded.

[0101] Optionally, the positioning pin 8 can be an elastic rod.
