Description

Technical Field

[0001] This invention relates to the field of navigable vehicle technology, specifically to a navigable vehicle and a method for parking in water. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Current amphibious vehicles rely on powered hovering systems for underwater parking, resulting in high energy consumption. Traditional ship anchoring systems involve manual anchoring, which is slow, bulky, and unsuitable for automobiles. Underwater vehicle anchoring devices can achieve electric unlocking and retrieval, overcoming the shortcomings of manual anchoring and powered hovering. However, these devices are not currently used on navigable vehicles. When installing underwater vehicle anchoring devices on navigable vehicles, issues arise regarding installation location compatibility and preventing water from entering the vehicle's interior. Therefore, when applying underwater vehicles to navigable vehicles, without altering the layout of components such as tires and axles, selecting the installation location for the parking system and ensuring its sealing performance when the vehicle is wading through water are pressing technical problems that need to be solved in this field. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a navigable car and a parking method in water, so that the parking system using the anchoring device technology of underwater vehicles can be applied to navigable cars, and the added parking system will not affect the other equipment and components of the navigable car, reducing the design difficulty of the car and taking into account the needs of navigable cars for both land travel and water travel.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a navigable vehicle, including a vehicle body, the vehicle body having a rear trunk floor, and a parking system, the parking system including an anchor body connected to a hanger shaft, the hanger shaft being connected to a retraction mechanism, wherein the anchor body is disposed within a receiving cavity of a recessed structure in the rear trunk floor, the retraction mechanism is disposed above the recessed structure and located inside a sealing cover, the sealing cover being located within the rear trunk interior space of the vehicle body, and the bottom end of the sealing cover being sealed to the recessed structure.

[0006] When a car needs to be parked in water, the retraction mechanism releases the anchor body, which falls under its own weight until it penetrates the bottom of the water, thus parking the car. When it is necessary to release the parking state, the retraction mechanism drives the anchor body to rise, and the anchor body leaves the bottom of the water, thereby releasing the parking state.

[0007] Optionally, the retraction mechanism includes a winch mechanism fixed inside the sealed cover. The winch mechanism is connected to a drum, and a rope is wound on the drum. The movable end of the rope is connected to a hanging shaft, and the hanging shaft is fixedly connected to an anchor located in the internal space of the concave structure.

[0008] The winch mechanism can drive the drum to rotate around its own axis, thereby realizing the raising or lowering of the rope. When raising the rope, the rope can drive the hanging shaft and anchor body to rise. When lowering the rope, the anchor body and hanging shaft can fall under their own weight.

[0009] Optionally, the winch mechanism is located inside the first waterproof cover, which is fixed inside the sealed cover. The output shaft of the winch mechanism passes through the first waterproof cover and is connected to the drum, enabling it to drive the drum to rotate.

[0010] The first waterproof cover prevents water from entering the winch mechanism to avoid affecting its normal operation.

[0011] Optionally, a position sensor is also included. The position sensor is set at the top of the cavity inside the concave structure to detect whether the anchor body has risen into place inside the cavity, eliminating the need for manual anchor body positioning and adapting to the automation requirements of navigable vehicles.

[0012] Optionally, it also includes a guide wheel, which is rotatably connected to a guide wheel bracket. The guide wheel bracket is fixed inside the protective cover, and the rope passes around the guide wheel and is connected to the hanging shaft.

[0013] Optionally, multiple sets of locking mechanisms are also included, with each set including two oppositely arranged locking mechanisms. The position of the locking mechanisms corresponds to the top position of the hanging shaft when the anchor body is raised to the highest position, so that the locking mechanisms can lock and fix the hanging shaft when the anchor body is raised to the highest position.

[0014] Optionally, the locking mechanism includes a telescopic component, which is fixed inside the sealing cover. The telescopic component is arranged radially along the hanging shaft, and the telescopic part of the telescopic component is connected to the stop tongue. Correspondingly, the top end of the hanging shaft is provided with an annular stop. The telescopic component can drive the stop tongue to extend so that the stop tongue can move to below the annular stop when the anchor body is in the highest position.

[0015] The tongue extends below the annular baffle, which can transfer the force of the axle and anchor to the concave structure, thereby utilizing the rear trunk floor to jointly bear the gravity load of the anchor and axle.

[0016] Optionally, a second waterproof cover is provided on the outer periphery of the telescopic component, and the telescopic part of the telescopic component passes through the second waterproof cover and extends to the outside of the second waterproof cover.

[0017] The second waterproof cover can prevent water from entering the telescopic components and affecting their normal operation.

[0018] Optionally, the sealing cover is fitted around the top outer periphery of the concave structure. The sealing cover is fixed to the side of the concave structure by multiple fasteners and a sealing component is provided between the sealing cover and the side of the concave structure to achieve a sealed connection between the sealing cover and the concave structure.

[0019] The sealed enclosure creates a separate wet zone, preventing moisture from leaking out of the enclosure and into the rear trunk.

[0020] Secondly, embodiments of the present invention provide a method for operating a navigable vehicle underwater parking system: The release mechanism releases the anchor body, which falls under its own weight until it inserts into the bottom of the water, thus enabling the car to be parked in the water. The launching and retracting mechanism lifts the anchor body, causing it to detach from the bottom of the water and releasing the car from its parking position in the water.

[0021] The beneficial effects of this invention are as follows: The present invention relates to a navigable automobile and an underwater parking method. The parking system includes a retraction mechanism and an anchor body, adopting the structure of an underwater vehicle anchoring device. The anchor body is set within a recessed cavity formed by the concave structure of the rear trunk floor of the automobile body, utilizing the space of the spare tire well in the current rear trunk floor. Simultaneously, the retraction mechanism is positioned above the concave structure, thus utilizing the space of the rear trunk. Therefore, the entire parking system occupies only the space of the spare tire well and the interior of the rear trunk, without encroaching on the space of other parts of the automobile, and will not interfere with the automobile's power system, tires, axles, suspension mechanism, or other components. This design eliminates the need for redesigning the car's powertrain, tires, axles, and suspension system. Without requiring major modifications to the vehicle, the water tank-mounted vehicle anchoring device can be used for water-based parking of navigable cars. This overcomes the high energy consumption problem caused by current navigable cars relying on power-driven hovering. Furthermore, a sealing cover is installed, which is sealed to the concave structure, preventing water from entering the trunk when the car is wading through water. This ensures a tight seal and prevents water from entering the trunk and damaging items stored inside.

[0022] The navigable car and underwater parking method of the present invention are equipped with a locking mechanism that can lock the suspension shaft when the anchor body is in the highest position. When the car is not parked or driving on land, the car does not need to rely on the winch mechanism for locking, which reduces the equipment performance requirements of the winch mechanism.

[0025] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention.

They are merely used to facilitate the description of the invention and to simplify the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0027] Example 1 This embodiment provides a navigable vehicle, including a vehicle body and a parking system installed on the vehicle body. The parking system utilizes the current anchoring device technology of underwater vehicles, including a retraction mechanism and an anchor 1. The retraction mechanism is an electric retraction mechanism that can receive commands from the controller and operate. The retraction mechanism can retract and release the anchor 1. When the retraction mechanism releases the anchor 1, the anchor 1 can fall under its own weight until it is inserted into the silt at the bottom of the water to a set depth, thus achieving parking. The retraction mechanism can also use its own driving force to pull the anchor 1 out of the silt at the bottom of the water and drive the anchor 1 to rise and reset, thereby releasing the parking state.

[0028] The aforementioned mooring device technology is currently mainly applied to underwater vehicles, such as submarines and unmanned underwater vehicles, and not to navigable cars. Current navigable cars primarily rely on power hovering, resulting in high energy consumption. However, if the mooring device for underwater vehicles were applied to parking navigable cars, it could overcome the high energy consumption caused by power hovering. However, when the current underwater vehicle mooring device is working, the anchor body 1 needs to perform a vertical lifting motion, and the deployment and retrieval mechanism requires a certain amount of space. Therefore, how to position the anchor body 1 so that its vertical lifting motion does not interfere with the chassis or other components and equipment of the navigable car, and how to house the deployment and retrieval mechanism inside the car so as not to interfere with other equipment and components inside the car, are the technical problems faced when applying the underwater vehicle mooring device to navigable cars.

[0029] The navigable vehicle of this embodiment addresses the aforementioned technical problems by designing the installation location of the parking system. Specifically, the navigable vehicle of this embodiment is equipped with a parking system that employs underwater vehicle anchoring technology. Figures 1-2 As shown, the system includes an anchor body 1 and a retraction mechanism connected to the anchor body 1. The anchor body 1 is placed in the cavity 3 formed by the concave structure 2 of the rear trunk floor of the navigable vehicle body. The retraction mechanism is placed in the space of the rear trunk of the navigable vehicle. In current navigable vehicles, the rear trunk floor adopts a sheet metal structure. The cavity formed by the concave structure 2 of the rear trunk floor is used to place the spare tire, serving as a spare tire pit. In this embodiment, the spare tire pit is used as the installation space for the anchor body 1 of the parking system of the navigable vehicle. The anchor body 1 is placed in the cavity 3 formed by the concave structure 2. Since the cavity 3 formed by the concave structure 2 is directly exposed to the external environment below the trunk floor, there are no other key moving parts or precision equipment. Therefore, during the raising and lowering of the anchor body 1, it will not interfere with other chassis structures such as the wheel axles and suspension of the vehicle, and will not affect the distribution and arrangement of other parts and equipment of the vehicle chassis, thus ensuring the integrity of the vehicle chassis and other structures.

[0030] Meanwhile, when the parking system is not in use, the anchor 1 can retract into the cavity 3 formed by the concave structure 2. When the navigable vehicle is driving on land, because the anchor 1 is retracted into the cavity 3 formed by the concave structure 2, the anchor 1 will not protrude from the bottom surface of the vehicle body or the distance from the bottom surface of the anchor 1 is relatively small. When the anchor is raised to the highest position, the ground clearance is not less than 180mm, which meets the minimum ground clearance requirement of the vehicle body. Therefore, the anchor 1 will not touch the ground when the navigable vehicle is driving on land, avoiding the anchor affecting the normal driving of the navigable vehicle on land.

[0031] The retraction mechanism is located in the space above the concave structure 2, that is, the retraction mechanism is located in the interior space of the rear trunk of the vehicle body, and will not occupy other space inside the vehicle body. This avoids interference between the retraction mechanism and other parts and equipment inside the vehicle body, and the distribution layout of other equipment inside the vehicle body does not need to be changed.

[0032] Since the retractable mechanism is connected to the hanging shaft 4 below it, the hanging shaft 4 needs to pass through the top part of the concave structure 2 through the through hole opened on the top surface of the concave structure 2. Therefore, in order to prevent water from entering the interior space of the luggage compartment, a sealing cover 5 is provided on the outer periphery of the retractable mechanism. The retractable mechanism is located in the space formed by the sealing cover 5, and the sealing cover 5 is sealed to the concave structure 2.

[0033] Because the sealing cover 5 is sealed to the concave structure 2, an independent wet area is formed inside the sealing cover 5. Therefore, water entering the sealing cover 5 during the wading process of the navigable vehicle will not flow out to the outside of the sealing cover 5. Thus, water will not enter the interior space of the trunk, which can prevent water from corroding the objects inside the trunk and meet the wading conditions of the navigable vehicle.

[0034] The navigable vehicle of this embodiment, based on the overall structure of the current navigable vehicle, utilizes the space of the spare tire pit formed by the recessed structure 2 of the rear trunk floor and part of the space inside the rear trunk to install a parking system. The rest of the navigable vehicle structure can adopt the technology of the current navigable vehicle, and will not be described in detail here.

[0035] The parking system of the navigable car in this embodiment and its installation method on the car body will be described in detail below.

[0036] In this embodiment, the navigable vehicle has an anchor body 1 installed in the cavity 3 formed by the recessed structure 2 in the rear luggage compartment floor of the vehicle body, and a retraction mechanism is installed in the space of the rear luggage compartment.

[0037] The anchor body 1 can adopt the anchor body structure of the current underwater vehicle anchoring device, and its specific structure will not be described in detail here.

[0038] Furthermore, in order to ensure that the anchor body 1 can be stably inserted into the silt at the bottom of the water under its own weight, and to ensure that the depth of the anchor body 1 inserted into the silt at the bottom of the water is not less than 180mm, thereby ensuring the fixation strength with the silt at the bottom of the water, the weight of the anchor body 1 is not less than 4kg. At the same time, considering that an excessively heavy anchor body 1 will increase the energy consumption of the vehicle when it is in motion, in this embodiment, the weight of the anchor body 1 is preferably 4kg.

[0039] It is understandable that the weight of the anchor body 1 can be set according to the weight of the vehicle body. When the weight of the vehicle body is large, the weight of the anchor body 1 can be increased as needed. Those skilled in the art can set the weight of the anchor body 1 according to actual needs, which will not be described in detail here.

[0040] The anchor body 1 is connected to the launching and retracting mechanism via the hanging shaft 4. The anchor body 1 and the hanging shaft 4 are made of stainless steel, which has strong rust resistance. It is understood that the anchor body 1 and the hanging shaft 4 can also be made of other metal materials, such as titanium alloy or aluminum alloy, and an anti-rust coating can be applied to the surface of the anchor body 1 and the hanging shaft 4.

[0041] Preferably, existing anti-rust paint can be used for the anti-rust coating, which will not be described in detail here.

[0042] The anchor body 1 is fixedly connected to the lower end of the hanging shaft 4, and the upper end of the hanging shaft 4 is connected to the launching and retracting mechanism.

[0043] In this embodiment, the hanging shaft 4 is a cylindrical shaft with a circular cross-section. It is understood that the cross-section of the hanging shaft 4 can also be a square or a rectangle. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.

[0044] The winding and unwinding mechanism includes a winch mechanism 6 installed inside the sealed cover 5. The output shaft of the winch mechanism 6 is connected to the drum 7, and the winch mechanism 6 can drive the drum 7 to rotate around its own axis.

[0045] The drum 7 is a cylindrical tube with a rope wound around it. The movable end of the rope is connected to the upper end of the hanging shaft 4.

[0046] Specifically, the drum 7 includes a cylindrical body with annular protrusions at both ends to form limiting platforms. The rope is wound around the area between the two limiting platforms on the drum. The limiting platforms are used to limit the rope and prevent it from detaching from the drum, ensuring that the rope can be stably wound around the drum under vibration conditions when the navigable vehicle is in motion.

[0047] The winch mechanism 6 can drive the drum 7 to rotate around its own axis. The rotation of the drum 7 can realize the winding and unwinding of the rope. When the drum 7 rotates in the forward direction and releases the rope, the anchor body 1 can fall freely under its own weight. When the anchor body 1 is inserted into the silt at the bottom of the water, the parking state is realized. When the drum 7 rotates in the reverse direction, the driving force provided by the winch mechanism 6 can be used to wind up the rope, thereby driving the anchor body 1 to rise. The anchor body 1 leaves the silt at the bottom of the water, thereby realizing the release of the parking state.

[0048] Furthermore, in the parking state, in order to ensure that the rope has sufficient strength to pull the car body and keep the car body in the parking state, the rope is a chain 8.

[0049] Furthermore, since the chain 8 needs to move in water, it is made of stainless steel.

[0050] Understandably, chain 8 can also be made of other metal materials that meet the strength requirements, and an anti-rust coating can be applied to the surface of the chain.

[0051] When the rope uses chain 8, the end of the rope is connected by a hanging ring set at the upper end of the hanging shaft 4.

[0052] In another embodiment, the rope may also be made of steel wire rope with a rust-proof coating on its surface.

[0053] When the rope is made of steel wire rope, the movable end of the steel wire rope is tied and fixed to the hanging shaft 4 by the binding ring provided at the upper end of the hanging shaft 4.

[0054] Those skilled in the art can choose the type of rope according to actual needs, which will not be described in detail here.

[0055] Preferably, the rope is made of stainless steel chain, which has high structural strength and strong load-bearing capacity. The chain 8 can be tensioned to generate a tensile force of more than 5000N to achieve forced parking of the entire vehicle.

[0056] The hoisting mechanism 6 can be any device capable of outputting rotational motion.

[0057] In one embodiment, the hoisting mechanism 6 is a motor, which can be a stepper motor or a servo motor, depending on actual needs. The motor is fixed on a motor mount, which is fixed on the upper surface of the concave structure 2, or the motor mount is fixed on the sealing cover 5.

[0058] When the motor mount is installed in the sealing cover 5, the sealing problem between the motor mount and the sealing cover 5 needs to be considered. Therefore, in order to simplify the structure and design, the motor mount is fixedly connected to the upper surface of the concave structure 2.

[0059] The motor mount also adopts a sheet metal structure with an anti-rust coating on its surface. The motor mount is fixedly connected to the upper surface of the concave structure 2 by multiple bolts or directly welded to the upper surface of the concave structure 2.

[0060] Preferably, the motor mount is fixed to the upper surface of the recessed structure 2 by multiple bolts.

[0061] The motor is detachably fixed to the motor mount by multiple bolts, which secures the motor inside the sealed cover 5. The motor and the motor mount are detachably fixed, making it convenient to replace and repair the motor.

[0062] The output shaft of the motor is connected to the drum 7, which can drive the drum 7 to rotate around its own axis.

[0063] In this embodiment, the motor is connected to the vehicle controller of the navigable vehicle and can receive instructions from the vehicle controller to work. The control wire of the motor passes through the wire hole provided on the sealing cover 5 and is connected to the vehicle controller of the navigable vehicle. The control wire of the motor can be routed inside the vehicle body according to the vehicle body structure, which will not be described in detail here.

[0064] Furthermore, a wire harness seal is provided between the motor control line and the wire hole of the sealing cover 5. The wire harness seal can be made using existing technology and will not be described in detail here.

[0065] Since moisture can enter the sealed cover 5, a first waterproof cover is provided around the motor to prevent moisture from affecting its operation. The motor is located inside the first waterproof cover, and the first waterproof cover is sealed and fixedly connected to the motor base. The first waterproof cover can prevent moisture from entering the motor and affecting its normal operation.

[0066] The first waterproof cover also adopts a sheet metal structure, and its inner and outer surfaces are coated with an anti-rust coating. The anti-rust coating can be any existing anti-rust paint, which will not be described in detail here. In one embodiment, the first waterproof cover is welded to the motor base, and the weld between the first waterproof cover and the motor base is used to achieve a seal. In another embodiment, the bottom edge of the first waterproof cover is provided with a flange to form a mounting plate. The mounting plate is fixed to the motor base with screws, and a rubber sealing ring is provided between the mounting plate and the motor base to achieve a seal.

[0067] Preferably, the first waterproof cover is fixed to the motor mount with a mounting plate and screws, which facilitates disassembly for motor inspection and replacement.

[0068] The motor's output shaft passes through the opening on the first waterproof cover and is then coaxially and fixedly connected to one end of the drum 7.

[0069] Furthermore, a rubber sealing ring is provided between the motor's output shaft and the opening to prevent moisture from entering the first waterproof cover through the gap between the motor's output shaft and the opening, thus affecting the normal operation of the motor.

[0070] In this embodiment, the winch mechanism 6 uses a motor. In other embodiments, the winch mechanism 6 can also use a rotary cylinder. In this case, it is necessary to configure an air tank connected to the rotary cylinder and a corresponding valve group. The valve group is connected to the vehicle controller of the navigable vehicle.

[0071] It is understandable that the hoisting mechanism 6 can be any device capable of outputting rotational motion. Those skilled in the art can choose according to actual needs, and will not be described in detail here.

[0072] In this embodiment, if the movable end of the rope is directly connected to the upper end of the hanging shaft 4, the installation height of the drum 7 must be higher than the height of the upper surface of the hanging shaft 4 when it is in the highest position. When the length of the rope above the hanging shaft 4 is the set requirement value, the height of the entire sealing cover 5 needs to be improved due to the large radius of the drum 7, which increases the requirements for the height of the interior space of the rear luggage compartment.

[0073] Therefore, in this embodiment, a guide wheel 9 is provided inside the sealing cover 5. The guide wheel 9 is located at a set position above the upper end of the hanging shaft 4. After the rope passes around the guide wheel 9, its movable end is connected to the upper end of the hanging shaft 4.

[0074] The guide wheel 9 is rotatably connected to the guide wheel frame, and the guide wheel frame is connected to the sealing cover 5 or fixedly connected to the upper surface of the concave structure 2.

[0075] Preferably, the guide wheel frame is fixedly connected to the upper surface of the concave structure 2, without the need to consider sealing issues. In this embodiment, the guide wheel frame is fixed by welding or by bolts to the upper surface of the concave structure 2. Those skilled in the art can choose according to actual needs, and will not be described in detail here.

[0076] Because of the guide wheel 9, the installation height of the drum 7 and the hoisting mechanism 6 can be lower than the height of the upper surface of the hanging shaft 4 when it is in the highest position. Moreover, the guide wheel 9 has a small diameter, which reduces the height requirement of the sealing cover 5, thereby reducing the height requirement of the rear trunk of the navigable vehicle and greatly optimizing the space utilization of the rear trunk.

[0077] In this manner, after the chain 8 is wound around the drum 7, it extends diagonally upwards, passes over the guide wheel 9, and then its movable end extends downwards and connects to the upper end of the hanging shaft 4.

[0078] Furthermore, the guide wheel 9 has a concave surface, and the chain 8 is embedded in the concave surface. The concave surface acts as a limit for the chain 8, which can prevent the chain 8 from disengaging from the guide wheel 9 when vibration occurs during the operation of the navigable vehicle. This allows the entire parking system to be used in vibration conditions and enhances the parking system's adaptability to the external environment.

[0079] In this embodiment, the guide wheel 9 is made of stainless steel, and correspondingly, the guide wheel frame is also made of stainless steel, which has good rust resistance.

[0080] Understandably, the guide wheel 9 and the guide wheel frame can also be made of plastic or other metal materials. When made of materials that are prone to rust, an anti-rust coating needs to be applied to the surface.

[0081] In this embodiment, when the hanging shaft 4 is in the highest position, the upper end of the hanging shaft 4 needs to be located inside the sealing cover 5. Therefore, the top of the concave structure 2 is provided with a through hole for the hanging shaft 4 and the chain to pass through. The diameter of the through hole is larger than the diameter of the hanging shaft 4 so that the hanging shaft 4 can pass through smoothly.

[0082] In this embodiment, since the anchor body 1 is relatively heavy, relying solely on the locking function of the motor to lock the anchor body would place high demands on the motor. Therefore, in this embodiment, a locking mechanism is provided inside the sealing cover 5. When the anchor body 1 is in its highest position, the locking mechanism can cooperate with the hanging shaft 4 to lock and fix the hanging shaft 4, thereby locking and fixing the position of the anchor body 1. Using this method, it is not necessary to use the locking function of the motor to lock the anchor body 1, thus reducing the requirements on the motor.

[0083] Furthermore, in order to ensure the stability of locking the hanging shaft 4, the locking mechanism is provided in at least one set, and the same set includes two locking mechanisms arranged opposite to each other.

[0084] In this embodiment, a set of locking mechanisms is provided, and the two locking mechanisms in the set are arranged opposite each other, that is, the two locking mechanisms are arranged coaxially and facing each other.

[0085] Two locking mechanisms of the same group are symmetrically arranged on both sides of the through hole in the concave structure for the hanging shaft and chain to pass through, and the locking mechanisms on both sides of the through hole are symmetrically arranged with respect to the center of the through hole.

[0086] The locking mechanism includes a telescopic component 10, which is fixed inside the sealing cover 5. The telescopic component 10 is connected to the sealing cover 5 or to the top surface of the concave structure 2. Preferably, the telescopic component 10 is fixedly connected to the top surface of the concave structure 2, and the rear luggage compartment bottom plate is used as the support structure.

[0087] The telescopic component 10 is connected to the stop tongue 11. The telescopic component 10 can drive the stop tongue 11 to perform telescopic movement. When the telescopic component 10 drives the stop tongue 11 to extend, the stop tongue 11 can cooperate with the hanging shaft 4 when it is in the highest position to lock and fix the hanging shaft 4. When the telescopic component 10 drives the stop tongue 11 to retract, the stop tongue 11 can release the cooperation state with the hanging shaft 4. At this time, the stop tongue 11 does not lock the hanging shaft 4. The drum 7 rotates and can release the chain 8, so that the hanging shaft 4 and the anchor body 1 fall freely under their own gravity.

[0088] The telescopic component 10 uses existing equipment capable of outputting linear telescopic motion.

[0089] In one embodiment, the telescopic component 10 is an electric telescopic rod, the fixed part of which is fixedly connected to the top surface of the concave structure 2 by bolts, and its telescopic part is connected to the tongue 11.

[0090] When the telescopic component 10 is an electric telescopic rod, the electric telescopic rod is connected to the vehicle controller of the navigable vehicle and can receive instructions from the vehicle controller of the navigable vehicle to perform telescopic movements.

[0091] In another embodiment, the telescopic component 10 is a cylinder, the cylinder body is connected to the top surface of the concave structure 2, and its piston rod is connected to the stop tongue 11.

[0092] When using this setup, it is necessary to configure an air tank connected to the cylinder and a corresponding valve group, which is connected to the vehicle controller of the navigable vehicle.

[0093] Since no additional components are required when the telescopic component 10 is an electric telescopic rod, it is preferable to use an electric telescopic rod for the telescopic component 10 in this embodiment.

[0094] The control cable of the electric telescopic pole extends out of the sealing cover 5 through the wiring hole and connects to the vehicle controller of the navigable vehicle. The control cable can be routed inside the vehicle body as needed, which will not be described in detail here.

[0095] Furthermore, a wire harness seal is provided between the control cable and the wire hole of the electric telescopic pole to seal the control cable and the sealing cover.

[0096] The wire harness seals can be made using existing technology, and will not be described in detail here.

[0097] Furthermore, a second waterproof cover is provided around the outer periphery of the electric telescopic pole, with the electric telescopic pole located inside the space of the second waterproof cover. The second waterproof cover is sealed and fixedly connected to the top surface of the recessed structure 2. The second waterproof cover can prevent moisture from entering the electric telescopic pole and affecting its normal operation.

[0098] The second waterproof cover also adopts a sheet metal structure, and its outer surface is coated with an anti-rust coating. The anti-rust coating can be any existing anti-rust paint, which will not be described in detail here. In one embodiment, the second waterproof cover is welded and fixedly connected to the top surface of the concave structure 2, and the seal is achieved through the weld. In another embodiment, the bottom edge of the second waterproof cover is provided with a flange to form a mounting plate. The mounting plate is fixedly connected to the top surface of the concave structure 2 by screws, and a sealing ring is provided between the mounting plate and the top surface of the concave structure for sealing.

[0099] Preferably, the second waterproof cover is fixedly connected to the top surface of the recessed structure 2 by a mounting plate and screws, which facilitates disassembly for maintenance and replacement of the electric telescopic rod.

[0100] The telescopic part of the electric telescopic pole extends out of the second waterproof cover through the opening provided in the second waterproof cover, and a rubber sealing ring is provided between the telescopic part of the electric telescopic pole and the second waterproof cover to achieve a seal, preventing moisture from entering the interior of the second waterproof cover from the gap between the opening of the second waterproof cover and the telescopic part of the electric telescopic pole, so as to affect the normal operation of the electric telescopic pole.

[0101] The electric telescopic rod drives the stop tongue 11 to extend, and the stop tongue 11 can cooperate with the hanging shaft 4 to lock the hanging shaft 4 and the anchor body 1.

[0102] In the first embodiment, the tongue 11 is an arc-shaped plate that matches the hanging shaft 4. The two tongues 11 form a clamp structure, and the hanging shaft 4 is locked and fixed by the pressing force of the two arc-shaped plates.

[0103] In this embodiment, it is preferable to process anti-slip textures or apply an anti-slip coating to the surface of the arc plate that is in contact with the hanging shaft 4 to increase the friction between the arc plate and the hanging shaft 4.

[0104] In another second embodiment, the upper end of the hanging shaft 4 is provided with an annular stop 12, and the stop tongue 11 is a stop block, which is an arc-shaped block, a cube block, or a block of other shapes.

[0105] Correspondingly, the diameter of the through hole on the top surface of the concave structure 2 is larger than the diameter of the annular baffle 12, so that the annular baffle 12 can pass smoothly through the through hole.

[0106] In this configuration, when the hanging shaft 4 is at its highest position, the electric telescopic rod can extend the stop tongue 11 below the annular stop 12. The stop tongue 11 engages with the lower surface of the annular stop 12, thereby restricting the downward movement of the hanging shaft 4 and locking the anchor body 1 and the hanging shaft 4. The telescopic stroke of the electric telescopic rod can allow the stop tongue 11 to contact the hanging shaft 4 or not. When the telescopic stroke of the electric telescopic rod allows the stop tongue 11 to contact the hanging shaft 4, a flexible pad can be provided on the side of the stop tongue 11 that contacts the hanging shaft 4 to prevent the stop tongue 11 from causing collision damage to the hanging shaft 4.

[0107] The flexible pad can be made of rubber or sponge, and those skilled in the art can choose according to actual needs.

[0108] In the first embodiment, the friction between the arc plate and the hanging shaft 4 is used to lock the hanging shaft. Since the anchor body 1 is heavy, the pressure applied by the electric telescopic rod is large, which places high demands on the electric telescopic rod. Therefore, the locking mechanism of this embodiment adopts the second embodiment, in which an annular baffle 12 is provided at the upper end of the hanging shaft 4. In this way, the downward force generated by the weight of the hanging shaft 4 and the anchor body 1 can be transmitted to the concave structure 2 through the baffle tongue 11, so that the weight of the hanging shaft 4 and the anchor body 1 can be jointly borne by the rear luggage compartment floor plate, which reduces the pressure required for the electric telescopic rod.

[0109] The parking system also includes a position sensor 13, which is installed at a set position on the upper side of the concave structure 2 to detect whether the anchor body 1 has been raised to the highest position.

[0110] In this embodiment, multiple position sensors 13 are provided, preferably two, which are arranged opposite to each other, that is, on two opposite sides of the concave structure. This arrangement of one position sensor 13 ensures the accuracy of the detection results.

[0111] In one embodiment, the position sensor 13 is a ranging sensor. For example, position sensor 13 uses a laser rangefinder, which measures distance by calculating the time it takes for a laser pulse to travel from emission to reflection. Laser rangefinders offer high accuracy and fast response.

[0112] The position sensor 13 can also be an ultrasonic ranging sensor, which emits high-frequency ultrasonic pulses and calculates the time it takes for the sound waves to reflect back after encountering an obstacle, then combines this with the speed of sound to determine the distance. Ultrasonic ranging sensors are low-cost, unaffected by light or color, and can penetrate smoke and dust.

[0113] The position sensor 13 can also be an infrared ranging sensor. The sensor emits infrared light, which is reflected by the object and falls on the internal photosensitive element. The distance is calculated using trigonometric functions based on the position (angle) of the reflected light's landing point. Infrared sensors are small, low-cost, and have a fast response speed.

[0114] The position sensor 13 can also be a radar ranging sensor, which emits radio waves and calculates the distance by analyzing the frequency changes of the reflected waves. When the position sensor uses a radar ranging sensor, it has extremely strong penetrating power and can work stably in harsh weather conditions such as rain, snow, fog, and dust.

[0115] When the position sensor 13 is a ranging sensor, considering the usage environment of the navigable vehicle, an ultrasonic ranging sensor or a radar ranging sensor is preferred.

[0116] The ranging sensor is connected to the vehicle controller of the navigable vehicle and can transmit the detected information to the vehicle controller.

[0117] When the distance detected by the distance measuring sensor increases sharply, it indicates that the anchor 1 leaves the receiving cavity 3 of the concave structure 2 and falls freely. When the distance detected by the distance measuring sensor decreases to the set value, it indicates that the anchor 1 is retracted into the receiving cavity 3 of the concave structure 2. At this time, the distance measuring sensor sends a signal to the vehicle controller, and the vehicle controller controls the hoisting mechanism 6 to stop working, stopping the upward movement of the anchor 1 and preventing the anchor 1 from colliding with the rear luggage compartment floor.

[0118] When the above method is used, the position sensor 13 detects the distance between itself and the side of the anchor body 1. When the position sensor 13 is a distance measuring sensor, the position sensor 13 can also be installed on the top surface of the concave structure 2, and the distance measuring sensor 13 directly detects the distance between itself and the top surface of the anchor body 1.

[0119] In the second embodiment, the position sensor 13 is a proximity switch, which is mounted on the side of the recessed structure. Correspondingly, the top of the hanging shaft 4 is provided with a baffle that can contact the proximity switch.

[0120] The proximity switch is connected to the vehicle controller of the navigable vehicle and can send signals to the vehicle controller.

[0121] When the position sensor 13 uses a proximity switch, the hanging shaft 4 rises under the drive of the winch mechanism 6. When the baffle of the hanging shaft 4 touches the proximity switch, the proximity switch can send a signal to the vehicle controller of the navigable vehicle. The vehicle controller of the navigable vehicle controls the winch mechanism 6 to stop working, stop the upward movement of the anchor body 1, and prevent the anchor body 1 from colliding with the rear trunk floor.

[0122] It is understood that the proximity switch can also be installed on the top surface of the recessed structure 2, and correspondingly, the baffle is also installed on the top surface of the anchor body 1.

[0123] Those skilled in the art can select the type of position sensor 13 according to actual needs, which will not be described in detail here.

[0124] By setting position sensor 13, the positioning error of anchor body 1 during retrieval is no more than 5mm. That is, when anchor body 1 is retrieved to the highest position, the positioning error between it and the highest target position is no more than 5mm. The positioning of anchor body 1 does not require manual positioning, which is convenient for the driver's operation and adapts to the automation requirements of navigable vehicles.

[0125] The bottom end of the sealing cover 5 is sealed to the top of the concave structure 2 to fix the sealing cover 5.

[0126] The sealing cover 5 also adopts a sheet metal structure, preferably with an anti-rust coating on its inner and outer surfaces.

[0127] In one embodiment, the bottom end of the sealing cover 5 is provided with a flange, which is welded and fixed to the top surface of the concave structure 2.

[0128] Alternatively, the flange can be fixed to the top surface of the concave structure 2 by bolts. When the flange is fixed to the top surface of the concave structure 2 by bolts, a sealing component is provided between the flange and the top surface of the concave structure for sealing.

[0129] In another embodiment, the bottom end of the sealing cover 5 is fitted around the top outer periphery of the concave structure 2, and the bottom end of the sealing cover 5 is welded and fixed to the top of the concave structure 2.

[0130] Alternatively, the sidewall of the sealing cover 5 is fixedly connected to the concave structure 2 by multiple screws, and a sealing component is provided between the inner sidewall of the sealing cover 5 and the outer sidewall of the concave structure 2 for sealing.

[0131] Preferably, multiple screws are evenly distributed at equal intervals along the connection position between the sealing cover 5 and the concave structure 2 to ensure the uniformity of the fixing of the sealing cover 5 at each position on the concave structure 2, thereby ensuring the sealing effect of the sealing component.

[0132] Rubber sealing rings are sufficient for sealing components, and will not be described in detail here.

[0133] By designing the sealing components, moisture can only enter the interior of the sealing cover 5 through the through-holes on the top surface of the concave structure 2, and will not flow out to the outside of the sealing cover 5 and into the interior space of the rear luggage compartment, thus preventing moisture from corroding the items placed inside the rear luggage compartment.

[0134] Preferably, the outer side of the sealing cover 5 is provided with a decorative layer, the material of which is the same as the material of the decorative layer on the upper surface of the trunk floor of the vehicle body, thus satisfying the requirements of aesthetics and vehicle use comfort.

[0135] In this embodiment, the decorative layer is made of fabric or polyurethane skin, etc. Those skilled in the art can set it according to actual needs, and it will not be described in detail here.

[0136] Furthermore, the top surface of the concave structure 2 can also be set as an inclined surface oriented towards the through hole. When the anchor body 1 is in the retracted state, the annular baffle 12 is located above the top surface of the concave structure 2. The diameter of the through hole is larger than the diameter of the hanging shaft 4. Therefore, there is a certain gap between the through hole and the hanging shaft 4. When the navigable vehicle travels to land and leaves the water, the water entering the sealing cover 5 can flow along the top inclined surface of the concave structure 2 to the through hole and be discharged from the gap between the through hole and the hanging shaft 4. This realizes the drainage of the internal space of the sealing cover 5, preventing water from accumulating inside the sealing cover 5 and causing abnormal noise during vehicle operation, as well as corrosion of the internal parts and equipment of the sealing cover 5.

[0137] The navigable vehicle of this embodiment only adds a parking system, with the anchor 1 set in the receiving cavity 3 formed by the recessed structure 2 in the bottom plate of the rear trunk, the sealing cover 5 set inside the rear trunk, and the retraction mechanism set inside the sealing cover 5. The rest of the navigable vehicle structure can use existing technology and will not be described in detail here.

[0138] The parking system in this embodiment of the navigable vehicle includes a retraction mechanism and an anchor body 1. It adopts the structure of an underwater vehicle anchoring device. The anchor body is located within the cavity 3 formed by the recessed structure 2 in the rear trunk floor of the vehicle body, utilizing the space of the spare tire pit formed by the recess in the rear trunk floor of the navigable vehicle. Simultaneously, the retraction mechanism is located above the recessed structure 2, within the rear trunk space of the navigable vehicle. Therefore, the retraction mechanism utilizes the space of the navigable vehicle's rear trunk. Thus, the entire parking system only occupies the space of the spare tire pit and the interior of the rear trunk, without encroaching on the space of the navigable vehicle itself. The space in the rest of the vehicle body will not interfere with the position of the power system, tires, axles, suspension mechanism, crossbeams and other components of the navigable vehicle. The power system, tires, axles, suspension mechanism, crossbeams and other components of the navigable vehicle do not need to be redesigned, which greatly reduces the design difficulty of the navigable vehicle when adding a parking system. Without making major modifications to the navigable vehicle, the parking system using underwater vehicle anchoring device technology can be applied to the underwater parking of the navigable vehicle, overcoming the high energy consumption problem caused by the current navigable vehicle relying on power hovering.

[0139] Example 2 This embodiment provides a method for parking a navigable car in water as described in Embodiment 1: When the water depth sensor in the navigable vehicle detects a water depth of not less than 0.3m during the wading process, it sends a signal to the vehicle controller of the navigable vehicle. The vehicle controller then activates the parking system, which is in a standby state.

[0140] When the driver issues a parking command to the vehicle controller, the vehicle controller controls the electric telescopic rod to retract, causing the stop tongue 11 to retract and move away from the space below the annular stop platform 12. Then, the vehicle controller sends a command to the motor, which controls the drum 7 to rotate forward, releasing the stainless steel chain. The anchor body 1 falls freely in the water under its own weight until it inserts into the silt at the bottom of the water. The stainless steel chain generates tension, forcing the navigable vehicle to park.

[0141] When the driver issues a release command to the vehicle controller, the vehicle controller sends a command to the motor to control the motor to rotate in the opposite direction. Relying on the driving force of the motor, the stainless steel chain pulls the anchor 1 out of the silt at the bottom of the water and drives the anchor 1 and the hanging shaft 4 to rise. When the position sensor 13 detects that the anchor 1 has risen to the target highest position, it sends a signal to the vehicle controller. The vehicle controller controls the motor to stop working. Then the vehicle controller controls the electric telescopic rod to work. The electric telescopic rod extends and drives the stop tongue 11 to move to the bottom of the annular stop platform 12. The stop tongue 11 cooperates with the bottom surface of the annular stop platform 12 to lock the anchor 1 and the hanging shaft 4, completing the closed loop of anchor 1 retrieval.

[0142] The navigable vehicle of this embodiment is suitable for driving in wading conditions with water depths of 0.3m-4m. The response speed of the parking system is no more than 0.6s, and the positioning error of the anchor body 1 is no more than 5mm. When the anchor body 1 is retracted, the gap between the anchor body 1 and the ground is no less than 180mm, which meets the minimum ground clearance requirement of the vehicle and the requirements for land driving. At the same time, when driving in wading, the entire vehicle can be parked by inserting the anchor body 1 into the silt at the bottom of the water, without the need for power suspension parking, which reduces energy consumption and takes into account both land passability and the reliability of parking in water.

[0143] The navigable vehicle in this embodiment showed no rust after 800 hours of salt spray testing and can be stably parked in flowing water with a velocity of 2.5 m / s. It has strong adaptability to environmental conditions and good durability.

[0144] The parking system can be applied to new energy navigable vehicles and off-road amphibious vehicles with normal navigation capabilities. Those skilled in the art can install the parking system on the vehicle body according to actual needs, which will not be described in detail here.

[0145] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
