Description

Technical Field

[0002] RVs, also known as motorhomes, can be roughly divided into self-propelled and trailer types. Like a smaller version of a house, they have their own living facilities inside.

[0003] The parking area of ​​these vehicles is not always a level camping site, and the parking device needs to be leveled when used. In the prior art of leveling such a vehicle, at least a lifting mechanism and a level sensing device are included. Mechanical, electromechanical or hydraulic jacks are usually used to level the vehicle. Therefore, the parking device in the present subject can also be referred to as a jack.

[0004] For example, the prior patent "CN203411283U Jack with Ball Screw" mentioned in its specification that it can be used for electric thrusters such as RVs, but it has limited lighting, insufficient thrust, and low sealing level. Another example is the prior patent "US20100176359A1", which discloses a vehicle leveling device, but does not propose specific solutions on how to improve lighting, increase thrust, and improve sealing level. Or the "CN210340189U Electric Jack" is equipped with an LED light and can be used at night, but the LED light is facing downward in one direction, the lighting range is limited, and its lighting angle still cannot reach the optimal state.

[0005] The above devices all have their own defects. Therefore, the inventor has made improvements to the reduction box, lighting, control panel and other parts, and developed a new RV parking device, which resulted in this case. Utility Model Content

[0060] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0061] A parking device for a recreational vehicle mainly includes components including a motor 1, a lifting device 2, an outer cover assembly 3, a reducer 4, and an LED lamp 5.

[0062] The motor 1 provides power, and transmits the power to the lifting device 2 through the reducer 4, so that the lifting device 2 can complete the rising or falling action. The motor 1 in this embodiment is roughly cylindrical, and LED lights 5 are arranged around the outer surface of the motor 1 to achieve 360° all-round lighting. The outer cover assembly 3 encloses the motor 1, the reducer 4, and the upper end of the lifting device 2 inside to achieve a high level of sealing.

[0063] The motor shaft 11 of the motor 1 in this embodiment is vertically upward and parallel to the axis of the entire lifting device 2. The output power of the motor 1 is transmitted through the three-stage reduction in the reducer 4, and the three-stage reduction includes a primary reduction unit 41, a secondary reduction unit 42, and a tertiary reduction unit 43. The primary reduction unit 41 includes mutually meshing shaft teeth 411 and a primary large gear 412. The secondary reduction unit 42 includes a secondary pinion 421 and a secondary large gear 422 that are meshed with each other. The tertiary reduction unit 43 includes a tertiary pinion 431 and a tertiary large gear 432 that are meshed with each other.

[0064] The shaft teeth 411 in this embodiment are directly spirally processed on the motor shaft 11, so the shaft teeth 411 are spiral, and the tooth shape of the first-stage large gear 412 is helical, so that the shaft teeth 411 and the first-stage large gear 412 are meshed. The number of shaft teeth 411 in this embodiment is set to 4 teeth to increase the gear transmission ratio. Since the first-stage large gear 412 is the first deceleration, the torque and friction force it carries are small, so a plastic gear is used to reduce wear and reduce noise.

[0065] The first large gear 412 and the second small gear 421 are mounted on the first transmission shaft 44, the second large gear 422 and the third small gear 431 are mounted on the second transmission shaft 45, and the third large gear 432 is mounted on the shaft of the lifting device 2, which is mounted on the screw connecting shaft 241 in this embodiment. The second small gear 421 is meshed with the second large gear 422, and the third small gear 431 is meshed with the third large gear 432, to respectively complete the second and third reductions.

[0066] In this embodiment, all gears, including the first-stage large gear 412, the second-stage small gear 421, the second-stage large gear 422, the third-stage small gear 431, and the third-stage large gear 432 are installed on their respective corresponding shafts using double-layer sleeves. The double-layer sleeves can improve various performance indicators such as wear resistance, noise reduction, and smooth operation.

[0067] In this embodiment, the second transmission shaft 45 is in the middle of the shaft during the power transmission process, with the first transmission shaft 44 in front and the screw connecting shaft 241 in the back. The transmission at this position must be smooth, so an anti-jamming mechanism is designed here. Specifically, a toothed disc 451 is fixedly arranged on the second transmission shaft 45, and a plurality of protruding teeth 452 are formed on the outer periphery of the toothed disc 451, and the teeth 452 are arranged at equal intervals. The inner ring of the secondary large gear 422 has grooves 453 corresponding to the number of teeth 452, and the shape and position of the grooves 453 match the teeth 452, and there is a gap 454 between the side of the teeth 452 and the groove wall of the groove 452.

[0068] When the motor 1 rotates forward, the power is transmitted to the first transmission shaft 44 through the meshing of the shaft teeth 411 and the first large gear 412, and the first transmission shaft 44 rotates in the opposite direction to the motor shaft 11 of the motor 1. The second small gear 421 meshes with the second large gear 422, and the power drives the second transmission shaft 45 to rotate in the opposite direction to the first transmission shaft 44 through the second large gear 422, that is, to rotate in the same direction as the motor shaft 11. The rotation of the second transmission shaft 45 drives the third small gear 431 to rotate, and the third large gear 432 meshing with the third small gear 431 rotates in the opposite direction, thereby driving the screw connecting shaft 241 to rotate in the same direction as the third large gear 432. Therefore, the motor shaft 11 rotates forward with the second transmission shaft 45, and the first transmission shaft 44 rotates in the opposite direction with the screw connecting shaft 241. The tooth portion 452 on the toothed disc 451 is in contact with one side of the groove 452 in the inner ring of the second large gear 422, and a gap 454 is retained on the other side.

[0069] When the motor 1 switches to reverse rotation, the motor shaft 11 reverses instantly, the first transmission shaft 44 rotates forward after the first-stage transmission, the second-stage pinion 421 drives the second-stage gear 422 to switch direction, and the second-stage gear 422 reverses. At this time, the second transmission shaft 45 still has a short-term forward rotation state by inertia. In this momentary short state, the second-stage gear 422 will reverse, while the second transmission shaft 45 is still rotating forward. Therefore, the toothed disc 451 and the second-stage gear 422 rotate in the opposite direction, and the toothed portion 452 and the groove 452, which originally retain the gap 454, gradually abut against each other, and the gap 454 is formed on the side that originally abutted. This changing state forms a buffer zone for switching, the purpose is to prevent the second transmission shaft 45 and the second-stage gear 422 from getting stuck when switching. After the reversal, the second transmission shaft 45 and the second-stage gear 422 keep rotating in the same direction, forming a reverse rotation, and then through the meshing of the third-stage pinion 431 and the third-stage gear 432, it is transmitted to the screw connecting shaft 241 for forward rotation.

[0070] The reducer 4 in this embodiment also includes a reducer housing, which is specifically divided into a base 46 and a cover plate 47. The first transmission shaft 44, the second transmission shaft 46, and the two ends of the screw connecting shaft 241 are respectively supported between the bottom of the base 46 and the cover plate 47, and the shaft teeth 411, the first large gear 412, the second small gear 421, the second large gear 422, the third small gear 431, and the third large gear 432 are all accommodated in the inner cavity formed after the base 46 and the cover plate 47 are buckled. The lower part of the screw connecting shaft 241 extends out of the base 46 and extends into the outer tube. The top of the upper part of the screw connecting shaft 241 extends out of the cover plate 47 of the reducer housing. When the power is off, or the motor 1 has no power output, or the power is insufficient, the screw connecting shaft 241 can be manually rotated through the part of the upper part of the screw connecting shaft 241 extending out of the cover plate 47. Therefore, in order to facilitate manual rotation of the screw connecting shaft 241, it is possible to consider making the upper top portion of the screw connecting shaft 241 into a shaft body with a polygonal cross-section. The screw connecting shaft 241 can be manually rotated by a wrench with a matching cross-section to prevent accidents.

[0071] In this embodiment, a reflective layer 12 made of a reflective material is firstly coated on the body of the cylindrical motor 1, and then LED lights 5 are circumferentially arranged outside the reflective layer 12. The LED lights 5 can be in the form of LED light strips, which are fixed in circles along the surface of the body. Adjacent circles of LED light strips can be attached to each other or leave a certain distance as needed, and are wound multiple times until the entire body is covered. Alternatively, a thin film-like LED light sheet can be used to directly surround the entire body. Alternatively, a hollow LED lamp tube can be made and directly fitted on the motor body. Regardless of the form, the motor body is surrounded by LED lights 5 in all directions, so that the parking device can achieve 360° all-round lighting without dead angles, improve the lighting brightness, and provide great convenience for use in low light or at night.

[0072] The outer cover assembly 3 includes an upper shell 31 and a lower shell 32. The upper shell 31 is in the form of a cover, which covers the lower shell 32, and the two can be sealed and fixed by fixing parts. In this embodiment, an opening is formed on the upper shell 31 corresponding to the position of the upper top of the screw connecting shaft 241, and a sealing end cover 33 is provided. When manual drive is required, the sealing end cover 33 is removed to expose the upper top of the screw connecting shaft 241, and force is applied to it with a wrench. In addition, a horizontal liquid level column 34 can be installed in the upper shell 31, and the horizontal state of the entire parking device can be judged by directly observing the position of the bubble of the horizontal liquid level column 34, which is convenient for leveling.

[0073] A motor cover 321 is formed in the lower shell 32 at a position corresponding to the motor 1. The motor cover 321 is made of a light-transmitting material, or the entire lower shell 32 is made of a light-transmitting material, so that the LED lamp 5 surrounding the motor 1 can greatly transmit light. The reflective layer 12 on the motor 1 can even out the brightness of the light and improve the penetration of the light of the LED lamp 5. An exhaust hole 322 is provided at the bottom center of the motor cover 321. The main purpose is that after the heat is generated inside the motor cover 321, water vapor is sometimes formed. The generated water vapor can be discharged in time through the exhaust hole 322 to ensure that the motor 1 and the LED lamp 5 of the motor cover 321 work normally.

[0074] The lifting device 2 includes a base column 21, an inner tube 22, and an outer tube 23. The base column 21 is a reference rod for placing on the ground, and a chassis extends from the bottom surface to increase the contact area of ​​the bottom surface. The inner tube 22 and the outer tube 23 are lifting rods, and the inner tube 22 and the outer tube 23 are hollow tubes. The base column 21 can be a hollow tube or a solid tube. In this embodiment, a hollow tube is used. A connecting plate 232 for connecting to a motorhome is fixedly provided on the outer wall of the outer tube 23, and a connecting hole 233 corresponding to the motorhome connecting frame is provided on the connecting plate 232.

[0075] The inner diameter of the inner tube 22 is larger than the outer diameter of the base column 21, and the inner diameter of the outer tube 23 is larger than the outer diameter of the inner tube 22. The upper end of the base column 21 is inserted into the lower end of the inner tube 22, and the upper end of the inner tube 22 is inserted into the lower end of the outer tube 23, so that the three are mutually fitted. The inner tube 22 and the base column 21 are fixed in a detachable manner. The base column 21 has a plurality of radial pin holes 211, and the plurality of pin holes 211 are parallel to each other and distributed at equal intervals. The inner tube 22 is provided with a radial connecting hole 221. When the base column 21 and the inner tube 22 are mutually fitted, the connecting hole 221 overlaps and penetrates one of the pin holes 211, and the positioning pin 212 is used to pass through the connecting hole 221 and the pin hole 211, so that the two are positioned, connected and fixed. When the foundation height is required to be shorter, the connecting hole 221 is aligned with the pin hole 211 with a lower horizontal height, and when the foundation height is required to be higher, the connecting hole 221 is aligned with the pin hole 211 with a higher horizontal height, and the two are assembled flexibly.

[0076] In order to facilitate the installation and removal of the positioning pin 212, a clamp 213 is provided on the positioning pin 212. The clamp 213 is formed by bending the two ends of a rod, one end of which is connected and fixed to an end of the positioning pin 212 exposed on the outside of the inner tube 22, and the other end forms a circular collar 214, which is sleeved on the other end of the positioning pin 212 exposed on the outside of the inner tube 22. When disassembling, the collar 214 is forced outward to separate from the end of the positioning pin 212, and the clamp 213 unlocks the positioning pin 212, and the positioning pin 212 can be pulled out of the connecting hole 221 and the pin hole 211. Conversely, the positioning pin 212 is inserted, and the collar 214 on the clamp 213 is put back on the protruding end of the positioning pin 212 to re-lock it.

[0077] The base column 21, the inner tube 22, and the outer tube 23 are fitted together. During the lifting process, they need to slide relative to the axial direction. Therefore, a first groove 215 is set on the outer side of the base column 21, and a second groove 222 is set on the outer side of the inner tube. The first groove 215 and the second groove 222 are axially arranged in the length direction of the groove body. The length of the groove body is consistent with the length of the tube body itself, and a V-shaped groove structure can be adopted. After the base column 21 and the inner tube 22 are fitted together, the second groove 222 is located on the outside, the first groove 215 is located on the inside, and the second groove 222 is stacked in the first groove 215, thereby realizing the radial positioning of the base column 21 and the inner tube 22. At the same time, when the inner tube 22 and the base column 21 are lifted and slid relative to the axial direction, the first groove 215 and the second groove 222 cooperate to realize the sliding guide function and improve the stability. A third groove 231 is set on the outer side of the outer tube 23, and the length direction of the groove body is also axially arranged, which can be a V-shaped groove structure. The length of the third groove 231 is shorter than that of the first groove 215 and the second groove 222. The third groove 231 overlaps the second groove 222 to achieve radial positioning of the inner tube 22 and the outer tube 23. At the same time, when the outer tube 23 and the inner tube 22 are lifted and slid relative to each other, the third groove 231 moves in the second groove 222 to play a good guiding role.

[0078] The lifting device 2 includes a screw rod 24 and a nut 25 that rotates on the screw rod 24. The nut 25 is fixed on the inner wall of the inner tube 22 to achieve position limiting and fixing in both the axial and radial directions. The outer surface of the nut 25 has a circle of protruding edge portions 251, and is provided with a concave bayonet 252, which is clamped on the inner surface of the second groove 222 of the inner tube 22, so that the nut 25 is radially positioned in the circumferential direction through the cooperation of the bayonet 252 and the second groove 22. At the same time, at the position where the nut 25 is located, the inner tube 22 punches out a plurality of holes inwardly, and each hole forms an inward folding edge 223, which is distributed on the upper and lower surfaces of the edge portion 251 of the nut 25, and a clamp is formed on the upper and lower surfaces, so that the nut 25 is fixed in the axial limit position. Therefore, the nut 25 is placed inside the inner tube 22, which is equivalent to forming an integral body with the inner tube 22 and cannot move arbitrarily relative to the inner tube. When the screw rod 24 rotates, since the nut 25 is restricted and cannot move, the screw rod 24 will generate a linear displacement upward or downward along the nut 25 to achieve lifting.

[0079] The upper end of the screw rod 24 is fixed to the lower end of the screw rod connecting shaft 241 through a pin 242. When the screw rod connecting shaft 241 rotates, the screw rod 24 is driven to rotate synchronously. In this embodiment, the end of the outer tube 23 is covered with a lining plate 234, and the reducer 4 is installed on the lining plate 234. The lining plate 234 is between the outer tube 23 and the reducer 4, forming an intermediate force barrier. The upper diameter of the screw rod connecting shaft 241 is smaller, and the lower diameter is larger. The upper part of the screw rod connecting shaft 241 passes through the lining plate 234, the base 46 of the reducer 4, and the cover plate 47, and finally extends out of the cover plate 47, while the lower part of the screw rod connecting shaft 241 is limited by the lining plate 234 and retained in the outer tube 23. A plane needle bearing 26 is sleeved on the screw connecting shaft 241. The plane needle bearing 26 is inside the outer tube 23. The lower end surface of the plane needle bearing 26 abuts against the step surface formed at the connection between the upper and lower parts of the screw connecting shaft 241, and the upper end surface abuts against the lower surface of the liner 234. Therefore, when the screw 24 rotates and rises in the nut 25, the screw 24 is pushed up, and the screw connecting shaft 241 is also pushed up together. The screw connecting shaft 241 applies the upward force to the liner 234 through the plane needle bearing 26, instead of directly applying this force to the base 46 of the reducer, so that the force and wear of the base 46 are reduced, and the reducer 4 and various components in the inner cavity of the reducer 4 are effectively protected.

[0080] The utility model is an electric parking device, so it is equipped with a corresponding electric control system. The electric control system includes a main control board 61 and a membrane switch panel 62. The main control board 61 is a central processing unit, which receives external signals, processes the signals, generates corresponding execution signals, and sends them to corresponding execution components to execute corresponding actions.

[0081] The membrane switch panel 62 is an input component of the main control board 61. The membrane switch panel 62 is arranged on the outer surface of the upper shell 31 of the outer cover assembly 3, and includes an LED light on key 621, an LED light off key 622, an up key 623, a down key 624, a one-key up key 625, and a one-key down key 626. The motor 1 and the LED light 5 are connected to the main control board 61 as output execution components. The output signal of the main control board 61 mainly controls the working state of the motor 1 and the LED light 5.

[0082] Press the LED light on key 621 to generate an input signal and send it to the main control board 61. The main control board 61 sends an on signal to the LED light 5 to turn on the LED light 5. Press the LED light off key 622 to generate an input signal and send it to the main control board 61. The main control board 61 sends an off signal to the LED light 5 to turn off the LED light 5.

[0083] The operator presses the rising button 623 to generate an rising input signal, which is sent to the main control board 61. The main control board 61 sends a forward signal to the motor, and the motor 1 rotates forward, and transmits power to the screw rod 24 through the reducer 4. The screw rod 24 rotates and rises linearly along the nut 25, driving the outer tube 23 to rise together. Once the operator removes the force applied to the rising button 623, the main control board 61 immediately controls the motor 1 to stop working, and the outer tube 23 stops rising. Similarly, the operator presses the descending button 624 to generate a descending input signal, which is sent to the main control board 61. The main control board 61 sends a reverse signal to the motor, and the motor 1 reverses, and transmits power to the screw rod 24 through the reducer 4. The screw rod 24 reverses and descends linearly along the nut 25, driving the outer tube 23 to descend together. Once the operator removes the force applied to the descending button 624, the main control board 61 immediately controls the motor 1 to stop working, and the outer tube 23 stops descending. The ascending button 623 and the descending button 624 need to be long pressed. Once the operator releases the button, the ascending or descending operation sent to them stops immediately.

[0084] The operator presses the one-touch rise button 625 once to generate an input signal and send it to the main control board 61. The main control board 61 sends a forward signal to the motor, and the screw rod 24 rotates to drive the outer tube 23 to the highest point before stopping. The operator presses the one-touch fall button 626 once to generate an input signal and send it to the main control board 61. The main control board 61 sends a reverse signal to the motor, and the screw rod 24 rotates to drive the outer tube 23 to the lowest point before stopping. Therefore, the one-touch rise button 625 and the one-touch fall button 626 are started with one button, and after pressing them once, the rise or fall operation is completed to the maximum state.

[0085] In the present application, in order to obtain better security, an unlocking reading unit 63 is also provided in the electric control system 6. The unlocking reading unit 63 is located on the outer surface of the upper shell 31 of the outer cover assembly 3, and is also integrated on the membrane switch panel 62, and is connected to the input end of the main control board 61 to read the unlocking signal. In the circuit control, the signal read in the unlocking reading unit 63 is the first level. The main control board 61 enters the normal working state only when the correct unlocking signal is collected. If the correct unlocking signal is not collected, the main control board 61 is always in the non-working state.

[0086] The signal form of the unlocking reading unit 63 can be various, such as fingerprint unlocking signal, electronic card signal, password signal, voice signal, facial recognition signal, etc. Different styles of unlocking reading units 63 can be installed corresponding to different forms, and the above forms can also be used in combination. In this way, during outdoor use, identity recognition must be performed first before the parking device can be unlocked, which improves the safety of outdoor use and increases the security level.

[0087] Combination Fig.12 , 13 and 14, the use process of the utility model is as follows: first, release the lock of the positioning pin 212 using the clamp 213, pull out the positioning pin 212, and separate the base column 21 from the parking device. The RV connecting frame 7 is ready, and the base column 21 is aligned with the mounting hole 71 on the RV connecting frame 7 and placed on the ground. Then the parking device is inserted downward from the top of the RV connecting frame mounting hole 71, and after fitting with the base column 21, the positioning pin 212 is inserted. Adjust the height of the parking device to a suitable position, align the connecting hole 233 on the connecting plate 232 of the outer tube 23 with the corresponding hole on the RV connecting frame, and connect and fix them, and the parking device is connected to the RV.

[0088] The parking device in this embodiment has an unlocking function, so identity recognition and authentication must be performed first. When the unlocking reading unit 63 reads a correct unlocking signal, the parking device is unlocked and the main control board 61 enters a normal working state.

[0089] The required operation is performed on the membrane switch panel 62. When the light is insufficient, the LED light 5 is turned on by the LED light on key 621. The LED light 5 in the utility model is a ring-shaped lighting, 360° all-round lighting without dead angles, and compared with the traditional LED one-way lighting, the brightness is improved, the field of vision is excellent, and the use is safer.

[0090] The other operation buttons of the membrane switch panel 62 control the parking device to rise or fall in different ways. The three-stage transmission adopted by the reducer 4 in the utility model can provide a large thrust of up to 2.5 tons. At the same time, a certain buffer space is reserved in the forward and reverse switching, so as to ensure that the motor 1 will not get stuck at the moment of reversing.

[0091] The outer cover assembly in the utility model can completely enclose the electrical components, the reducer 4, and the upper end of the lifting device 2 inside, and the waterproof and dustproof sealing level is as high as IP54.

[0092] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
