Description

Technical Field

[0001] This utility model relates to the technical field of parking equipment, and in particular to an extended cantilever charging parking machine. Background Technology

[0002] With the acceleration of urbanization and the rapid growth of car ownership, the parking problem has become increasingly prominent, especially in urban centers and residential areas. Traditional surface parking methods can no longer meet the ever-increasing parking demand. Mechanical parking equipment, as an effective solution, can significantly increase parking capacity within limited space and has therefore been widely used.

[0003] Lift-and-slide parking systems are the most widely used type of mechanical parking equipment. Their basic working principle involves the coordination of a lifting mechanism and a sliding mechanism to move the vehicle platform vertically and horizontally, thereby completing vehicle storage and retrieval operations. However, existing lift-and-slide parking systems face a key technical problem in their design and use: the lifting mechanism must bear the weight of the vehicle platform and the vehicle for extended periods.

[0004] In existing technology, after a vehicle is placed on a platform, the platform is suspended from the equipment frame by a lifting mechanism. The entire weight of the vehicle (typically 1.5-3 tons) and the weight of the platform itself must be borne by the transmission system of the lifting mechanism. The lifting transmission system includes components such as a motor, reducer, lifting chain, and guide wheels, all of which must continuously bear loads while the vehicle is parked. The motor brake must operate continuously to prevent the platform from descending, the lifting chain is always under high tension, and all transmission components are under constant stress. This continuous load-bearing operation mode brings many problems: First, long-term load-bearing leads to fatigue damage in the lifting transmission components; the lifting chain undergoes tensile deformation, gears and bearings wear faster, and the lifespan of the motor and brake is significantly shortened. Second, the continuous operation of the motor brake increases energy consumption and heat generation, affecting the equipment's energy efficiency. Third, frequent failures and replacements of transmission components increase maintenance costs and downtime, affecting normal user operation. Finally, long-term high-load operation may also lead to safety hazards, such as brake failure causing the platform to descend unexpectedly. Utility Model Content

[0005] This utility model provides an extended cantilever charging parking machine, which effectively solves the problem of fatigue damage caused by long-term load on the transmission components of the lifting mechanism, and significantly improves the reliability and service life of the equipment.

[0006] This utility model provides an extended cantilever charging parking machine, comprising: a support frame, the top of which is provided with a transverse guide rail; a transverse support, slidably mounted on the transverse guide rail; a first drive unit, mounted on the transverse support, for driving the transverse support to slide along the transverse guide rail; and a lifting mechanism, mounted on the transverse support, the lifting end of which is provided with a vehicle-carrying plate for carrying vehicles; wherein, the support frame is used to carry the vehicle-carrying plate that has been moved to the top of the support frame.

[0007] In one possible implementation, the lifting mechanism includes: a second drive unit disposed on the transverse support, the output end of the second drive unit being provided with a lifting end; a cantilever bracket connected to the lifting end, the cantilever bracket having a support portion extending to one side of the transverse support; wherein, the vehicle platform is disposed on the support portion of the cantilever bracket.

[0008] In one possible implementation, the transverse support is provided with a first lifting guide groove, and the support frame is provided with a second lifting guide groove, the top of the second lifting guide groove being connected to the bottom of the first lifting guide groove; the cantilever bracket includes a lifting guide wheel, which can slide along the first and second lifting guide grooves.

[0009] In one possible implementation, the support frame includes a support beam, and a transverse guide rail is disposed on the support beam. The transverse guide rail includes: a first guide rail disposed on the top of the support beam; and a transverse guide groove disposed on one side of the support beam in the direction of extension. The transverse support includes a frame and a support guide wheel and a limiting guide wheel disposed on the frame. The support guide wheel slides along the first guide rail, and the limiting guide wheel is slidably disposed in the transverse guide groove.

[0010] In one possible implementation, the first drive unit includes: a drive wheel rotatably mounted on the frame and abutting against the top of the support beam; and a first motor mounted on the frame, the output of which is connected to the drive wheel.

[0011] In one possible implementation, the support beam can extend and retract along its length, and the support frame further includes: an inner support column connected to the fixed end of the support beam; an outer support column connected to the telescopic end of the support beam, with a traveling roller at the bottom of the outer support column; and a third drive unit for driving the extension and retraction of the support beam.

[0012] In one possible implementation, the supporting beam includes: an outer sleeve, one end of which is connected to the top of the inner supporting column; and an inner sleeve, slidably disposed within the outer sleeve, the end of which is away from the inner supporting column and connected to the top of the outer supporting column; wherein the third drive unit includes: a third motor, disposed on the inner supporting column; a transverse rack, fixedly disposed on the outer wall of the inner sleeve; and a drive gear, rotatably disposed on the outer sleeve. The drive gear is connected to the power output end of the third motor and meshes with the transverse rack.

[0013] In one possible implementation, a first support wheel is rotatably provided at the end of the inner sleeve away from the outer support column, and the first support wheel abuts against the inner wall of the outer sleeve; and / or, a second support wheel is provided at the end of the outer sleeve away from the inner support column, and the second support wheel abuts against the top of the inner sleeve, and a transverse rack is provided at the bottom of the inner sleeve.

[0014] In one possible implementation, the second drive unit includes: a second motor mounted on a transverse support; and a lifting chain assembly connected to the output end of the second motor, with the movable part of the lifting chain assembly connected to the cantilever bracket.

[0017] This utility model provides an extended cantilever charging parking machine. A support frame is located at the bottom of the entire parking machine, and a transverse guide rail at its top provides sliding support for the lateral support bracket. A first drive unit drives the lateral support bracket to move along the guide rail. The lifting mechanism raises and lowers the vehicle platform from its initial position and moves it laterally above the support frame. At this point, the weight of the vehicle platform and the vehicle it carries is directly borne by the support frame. When the vehicle platform reaches a predetermined position above the support frame, the bottom surface of the vehicle platform contacts the top surface of the support frame, and the entire weight of the vehicle and the vehicle platform is directly transferred to the ground foundation via the support frame. After the vehicle platform contacts and bears the load, the lifting mechanism changes from a state of continuous support for the vehicle platform and vehicle weight to an unloaded state, no longer needing to continuously bear static loads. The platform-bearing mechanism changes the stress pattern of the parking equipment, solving the key problem of fatigue damage to transmission components caused by long-term load bearing in existing technologies. The transmission components of the lifting mechanism are in a stress-free natural state, eliminating fatigue damage at its source, significantly extending the equipment's service life, reducing the failure rate and maintenance costs, and achieving long-term stable operation of the equipment.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The following is combined Figure 1-12 This utility model provides an extended cantilever charging parking machine, including a support frame 1, a transverse support 2, a first drive unit 3, and a lifting mechanism 4, wherein: A transverse guide rail 11 is provided on the top of the support frame 1, wherein the transverse guide rail 11 extends along the length direction of the support frame 1.

[0035] The transverse support 2 is slidably mounted on the transverse guide rail 11.

[0036] The first drive unit 3 is mounted on the transverse support 2 and is used to drive the transverse support 2 to slide along the transverse guide rail 11.

[0037] The lifting mechanism 4 is mounted on the transverse support 2, and the lifting end of the lifting mechanism 4 is provided with a vehicle-carrying plate 41 for supporting the vehicle.

[0038] Among them, the support frame 1 is used to support the vehicle platform 41 that is moved to the top of the support frame 1.

[0039] In this invention, the support frame 1 is located at the bottom of the entire parking machine. The transverse guide rail 11 at its top provides sliding support for the transverse support bracket 2. The first drive unit 3 drives the transverse support bracket 2 to move along the guide rail. The lifting mechanism 4 lifts and moves the vehicle platform 41 from its initial position to above the support frame 1. At this point, the weight of the vehicle platform 41 and the vehicle it carries is directly borne by the support frame 1. When the vehicle platform 41 reaches the predetermined position above the support frame 1, the bottom surface of the vehicle platform 41 contacts the top surface of the support frame 1, and the entire weight of the vehicle and the vehicle platform 41 is directly transferred to the ground foundation via the support frame 1. After the vehicle platform 41 contacts and bears the weight of the vehicle platform 1, the lifting mechanism 4 changes from a state where it needs to continuously support the weight of the vehicle platform 41 and the vehicle to an unloaded state, no longer needing to continuously bear the static load. The platform load-bearing mechanism changes the stress mode of the parking equipment, solving the key problem of fatigue damage to the transmission components caused by long-term load bearing in the existing technology. The transmission components of the lifting mechanism 4 are all in a stress-free natural state, eliminating the problem of fatigue damage from the source, significantly extending the service life of the equipment, reducing the failure rate and maintenance costs, and achieving long-term stable operation of the equipment.

[0040] Specifically, when the vehicle platform 41 reaches the predetermined position above the support frame 1 through the coordinated movement of the lifting mechanism 4 and the transverse support 2, the bottom surface of the vehicle platform 41 contacts the top surface of the support frame 1, and the entire weight of the vehicle and the vehicle platform 41 is transferred to the ground through the support frame 1. At this time, the lifting mechanism 4 is in a relatively unloaded state, and its transmission chain, gears, motor and other components no longer bear continuous heavy loads, and only perform brief lifting actions when it is necessary to retrieve the vehicle.

[0041] like Figure 9 and 11 As shown, in a specific embodiment, when a car weighing 1.8 tons is parked on the car carrier 41, the lifting mechanism 4 of a traditional lifting parking device needs to continuously bear the total weight of the car carrier 41 and the vehicle, approximately 2.0 tons. This long-term load causes the lifting chain to be under high tension, and the motor and reducer also need to continuously provide holding torque, leading to fatigue in these components after several months of use. However, with the platform-supported structure of this invention, the car carrier 41 returns to its position on the support platform 1, and the lifting mechanism 4 is completely unloaded, effectively extending the service life of the equipment.

[0042] In related technologies, existing lifting parking equipment typically employs a continuous load-bearing lifting mechanism 4, with the car carrier 41 suspended from the lifting transmission system. During vehicle parking, the lifting chain remains stretched, and the motor brake needs to operate continuously to prevent the car carrier 41 from descending. This continuous load-bearing mode causes the lifting transmission components to be under constant stress, easily leading to chain stretching and deformation, accelerated gear wear, and motor overheating. This results in frequent equipment maintenance and a short service life. In this embodiment, however, the support frame 1 bears the weight of the car carrier 41 and the vehicle, transforming the lifting mechanism 4 from a continuous load-bearing state to an intermittent working state, significantly reducing the working stress on the transmission components. After the car carrier 41 returns to its position, the lifting chain is relaxed, and the motor and brake do not need to operate continuously, effectively reducing component fatigue damage and energy consumption, and improving the overall reliability and economy of the machine.

[0043] like Figure 1 As shown, in some embodiments, the lifting mechanism 4 includes: a second drive unit 42, disposed on the transverse support 2, the output end of the second drive unit 42 being provided with a lifting end; a cantilever bracket 43, connected to the lifting end, the cantilever bracket 43 having a support portion extending to one side of the transverse support 2; wherein, the vehicle plate 41 is disposed on the support portion of the cantilever bracket 43.

[0044] In this invention, the lifting end of the second drive unit 42 is connected to the cantilever bracket 43. The cantilever bracket 43 has a support portion extending to one side of the transverse support 2, and the vehicle carrier plate 41 is mounted on this support portion. The cantilever bracket 43 adopts a cantilever structure design, with the vehicle carrier plate 41 completely suspended on the outside of the transverse support 2. There are no pillars, fences, or other structural components obstructing the vehicle's path, providing a completely open storage and retrieval environment for the vehicle and fundamentally eliminating the risk of vehicle scratches that is common in traditional lifting parking equipment.

[0045] Specifically, the support portion of the cantilever bracket 43 extends from one side of the transverse support 2, and the vehicle platform 41 is fixed to the end of the support portion, forming a cantilever beam structure. When a vehicle drives into the vehicle platform 41, the driver's view is not obstructed by any structural components, and the opening of the doors and the entry and exit of personnel are not restricted by space. The cantilever design ensures openness around the vehicle, allowing even larger vehicles to be safely and conveniently accessed.

[0046] In related technologies, existing lifting parking equipment mostly adopts a frame structure with columns or fences on all sides, with the vehicle platform 41 enclosed inside the frame. This frame design obstructs the driver's view during vehicle storage and retrieval, increasing operational difficulty and collision risk. Especially for users with average driving skills, accurately parking within the limited frame space is quite challenging, easily leading to collisions between the vehicle and the equipment structure. However, in this embodiment, the cantilever structure of the cantilever bracket 43 completely eliminates visual and physical obstacles around the vehicle, making vehicle storage and retrieval as if operating on an open platform, significantly reducing the demands on driving skills. This open parking environment not only improves operational safety but also enhances user acceptance and confidence in the equipment.

[0047] like Figure 1 and 2 As shown, in some embodiments, the transverse support 2 is provided with a first lifting guide groove 21, and the support frame 1 is provided with a second lifting guide groove 12. The top of the second lifting guide groove 12 can be connected to the bottom of the first lifting guide groove 21. The cantilever bracket 43 includes a lifting guide wheel 431, which can slide along the first lifting guide groove 21 and the second lifting guide groove 12.

[0048] In this invention, the transverse support 2 is provided with a first lifting guide groove 21, and the support frame 1 is provided with a second lifting guide groove 12. The top of the second lifting guide groove 12 can be connected to the bottom of the first lifting guide groove 21. The cantilever bracket 43 includes a lifting guide wheel 431, which can slide along the first lifting guide groove 21 and the second lifting guide groove 12. The dual-stage lifting guide groove system provides precise trajectory control for the lifting movement of the cantilever bracket 43, ensuring that the vehicle platform 41 can be stably lifted and accurately positioned at the load-bearing position of the support frame 1.

[0049] Specifically, when the cantilever bracket 43 moves up and down, the lifting guide wheel 431 slides within the first lifting guide groove 21. The sidewall of the guide groove provides lateral constraint to the guide wheel, preventing the cantilever bracket 43 from horizontally shifting or swaying during the lifting process. When the cantilever bracket 43 rises to a specific height, connecting the first lifting guide groove 21 with the second lifting guide groove 12, the lifting guide wheel 431 can continue to move within the second lifting guide groove 12, achieving a smooth transition from the position of the transverse support 2 to the position of the support platform 1.

[0050] In one specific embodiment, when the vehicle platform 41 needs to be moved from the suspended position on the transverse support 2 to the load-bearing position on the support frame 1, the lifting guide wheel 431 first rises along the second lifting guide groove 12, and then smoothly transitions to the first lifting guide groove 21 to continue moving until it reaches the predetermined height. Throughout the lifting process, the cooperation between the guide wheel and the guide groove ensures the accuracy of the movement trajectory of the cantilever bracket 43, avoiding the problem of the vehicle platform 41 failing to return to its correct position due to positional deviation.

[0051] like Figure 4 and 5 As shown, in some embodiments, the support frame 1 includes a support beam 13, and a transverse guide rail 11 is disposed on the support beam 13. The transverse guide rail 11 includes: a first guide rail 111 disposed on the top of the support beam 13; and a transverse guide groove 112 disposed on one side of the extension direction of the support beam 13. The transverse support 2 includes a frame 22 and a support guide wheel 23 and a limiting guide wheel 24 disposed on the frame 22. The support guide wheel 23 slides along the first guide rail 111, and the limiting guide wheel 24 is slidably disposed in the transverse guide groove 112.

[0052] In this invention, the support frame 1 includes a support beam 13, and a transverse guide rail 11 is mounted on the support beam 13, including a first guide rail 111 and a transverse guide groove 112. The transverse movement bracket 2 includes a frame 22 and a support guide wheel 23 and a limiting guide wheel 24 mounted on the frame 22. The support guide wheel 23 slides along the first guide rail 111, and the limiting guide wheel 24 is slidably mounted in the transverse guide groove 112. The dual-guide wheel transverse movement guiding system separates the load-bearing function and the guiding function, realizing the reasonable distribution of load and precise control of the movement trajectory during transverse movement.

[0053] Specifically, the support guide wheel 23 mainly bears the weight load of the transverse support 2 and its load, rolling on the first guide rail 111, while the limiting guide wheel 24 slides within the transverse guide groove 112, mainly serving as a lateral limiting and guiding function. When the transverse support 2 moves along the transverse guide rail 11, the support guide wheel 23 bears the load in the vertical direction, and the limiting guide wheel 24 provides horizontal constraint. The two types of guide wheels each perform their respective functions to ensure the stability and accuracy of the transverse movement.

[0054] In some embodiments, the first drive unit 3 includes: a drive wheel 31, which is rotatably mounted on the frame 22 and abuts against the top of the support beam 13; and a first motor 32, which is mounted on the frame 22 and whose output end is connected to the drive wheel 31.

[0055] In this invention, the first drive unit 3 includes a drive wheel 31 and a first motor 32. The drive wheel 31 is rotatably mounted on the frame 22 and abuts against the top of the supporting beam 13. The output end of the first motor 32 is connected to the drive wheel 31. A friction drive method is adopted, transmitting power through the friction between the drive wheel 31 and the supporting beam 13. This avoids the use of complex transmission mechanisms such as gears and chains, simplifies the structure of the transmission system, and improves the system's reliability and ease of maintenance.

[0056] Specifically, the first motor 32 drives the drive wheel 31 to rotate, generating friction between the drive wheel 31 and the top surface of the support beam 13. This friction propels the transverse support 2 to move along the transverse guide rail 11. The contact area of ​​the friction drive can be designed as needed, and a suitable coefficient of friction can be obtained by adjusting the material and surface properties of the drive wheel 31 to ensure sufficient driving force under various working conditions.

[0057] In some embodiments, the support beam 13 can extend and retract along its length. The support frame 1 further includes: an inner support column 14 connected to the fixed end of the support beam 13; an outer support column 15 connected to the telescopic end of the support beam 13, with a traveling roller 17 provided at the bottom of the outer support column 15; and a third drive unit 16 for driving the support beam 13 to extend and retract.

[0058] In this invention, the supporting beam 13 is telescopic along its length. The inner supporting column 14 is connected to the fixed end of the supporting beam 13, and the outer supporting column 15 is connected to the telescopic end of the supporting beam 13 and has a traveling roller 17 at its bottom. The third drive unit 16 is used to drive the telescopic support beam 13 to extend and retract. The telescopic supporting beam 13 enables dynamic adjustment of the parking space width, providing ample parking space for vehicles to enter when parking, and retracting to its minimum size after parking to save space.

[0059] Specifically, when a vehicle needs to park, the third drive unit 16 drives the support beam 13 to extend outward, increasing the effective width of the parking space and providing a more spacious parking environment for the driver. After the vehicle is parked, the support beam 13 automatically retracts to its standard size, and the outer support column 15 moves smoothly via the bottom traveling rollers 17. The entire extension and retraction process is smooth and reliable. The extension and retraction function also allows the equipment to adapt to vehicles of different widths, providing suitable parking space for everything from compact cars to large SUVs.

[0060] In related technologies, traditional parking equipment typically has fixed parking space dimensions, requiring design based on the largest vehicle size, leading to wasted space when parking smaller vehicles. Fixed-size parking spaces also limit the equipment's applicability, failing to adequately accommodate the increasingly diverse vehicle specifications on the market. However, in this embodiment, the telescopic function of the supporting beam 13 enables intelligent management of parking space, dynamically adjusting the width according to actual needs. This ensures convenient parking for large vehicles while saving space for smaller vehicles. The flexible space configuration significantly improves the equipment's applicability and space utilization efficiency.

[0061] In some embodiments, the supporting beam 13 includes: an outer sleeve 131, one end of which is connected to the top of the inner supporting column 14; an inner sleeve 132, which is slidably disposed within the outer sleeve 131, one end of which is away from the inner supporting column 14 and connected to the top of the outer supporting column 15; wherein, the third drive unit 16 includes: a third motor 161, disposed on the inner supporting column 14; a transverse rack 162, fixedly disposed on the outer side wall of the inner sleeve 132; and a drive gear 163, rotatably disposed on the outer sleeve 131. The drive gear 163 is connected to the power output end of the third motor 161 and meshes with the transverse rack 162.

[0062] In this invention, the supporting beam 13 includes an outer sleeve 131 and an inner sleeve 132. One end of the outer sleeve 131 is connected to the top of the inner supporting column 14, and the inner sleeve 132 is slidably disposed inside the outer sleeve 131. The end of the inner sleeve 132 away from the inner supporting column 14 is connected to the top of the outer supporting column 15. The third drive unit 16 includes a third motor 161, a transverse rack 162, and a drive gear 163. The sleeve-type telescopic structure, combined with the rack and pinion transmission, provides a precise and reliable solution for the telescopic function of the supporting beam 13.

[0063] Specifically, the third motor 161 drives the drive gear 163 to rotate. The drive gear 163 meshes with the transverse rack 162 fixed to the outer wall of the inner sleeve 132, realizing precise movement of the inner sleeve 132 relative to the outer sleeve 131. The sleeve structure not only provides good guidance but also can withstand large loads, meeting the requirements for the support beam 13 to extend and retract under load. The gear and rack transmission has the characteristics of accurate transmission ratio and high positioning accuracy, ensuring the repeatability of the extension and retraction position.

[0064] In some embodiments, a first support wheel 133 is rotatably provided at one end of the inner sleeve 132 away from the outer support column 15, and the first support wheel 133 abuts against the inner wall of the outer sleeve 131; and / or, a second support wheel 134 is provided at one end of the outer sleeve 131 away from the inner support column 14, and the second support wheel 134 abuts against the top of the inner sleeve 132, and a transverse rack 162 is provided at the bottom of the inner sleeve 132.

[0065] In this invention, a first support wheel 133 is rotatably mounted on the end of the inner sleeve 132 away from the outer support column 15. The first support wheel 133 abuts against the inner wall of the outer sleeve 131. A second support wheel 134 is mounted on the end of the outer sleeve 131 away from the inner support column 14. The second support wheel 134 abuts against the top of the inner sleeve 132. A transverse rack 162 is located at the bottom of the inner sleeve 132. This multi-point support wheel configuration provides all-around support and guidance for the sleeve's extension and retraction, ensuring extremely high stability during the extension and retraction process.

[0066] Specifically, the first support wheel 133 includes multiple support wheels that abut against the inner top wall, inner bottom wall, and side wall of the outer sleeve 131, completely eliminating gaps in all directions between the inner and outer sleeves 131. The second support wheel 134 provides an additional support point at the end of the outer sleeve 131, forming a double-end support structure with the first support wheel 133. When the inner sleeve 132 slides inside the outer sleeve 131, multiple support wheels simultaneously contact the inner wall of the sleeve, providing a uniformly distributed support force and preventing deformation or jamming of the sleeve under load.

[0067] In this embodiment of the invention, the multi-point support wheel system replaces sliding contact with rolling contact, greatly reducing frictional resistance and wear. The all-around support configuration eliminates sleeve clearance, ensuring stable telescopic performance under various load conditions and significantly improving the system's reliability and service life.

[0068] In some embodiments, the second drive unit 42 includes: a second motor 421, which is disposed on the transverse support 2; and a lifting chain assembly 422, which is connected to the output end of the second motor 421, and the movable part of the lifting chain assembly 422 is connected to the cantilever bracket 43.

[0069] In this invention, the second drive unit 42 includes a second motor 421 and a lifting chain assembly 422. The lifting chain assembly 422 is connected to the output end of the second motor 421, and the movable part of the lifting chain assembly 422 is connected to the cantilever bracket 43. The chain lifting transmission system not only provides precise and reliable lifting power for the cantilever bracket 43, but more importantly, when the vehicle platform 41 is returned to the support frame 1, the lifting chain assembly 422 can enter a slack state, realizing true frame load-bearing.

[0070] Specifically, the second motor 421 drives the lifting chain assembly 422 through a reducer. The lifting chain assembly 422 controls the lifting position of the cantilever bracket 43 by extending and retracting the chain. When the vehicle platform 41 is raised above the support frame 1 and contacts the frame, the weight of the vehicle platform 41 is borne by the support frame 1. At this time, the lifting chain assembly 422 no longer needs to bear the weight of the vehicle platform 41 and the vehicle, and the chain is in a slack state. The slack state severs the mechanical connection between the lifting mechanism 4 and the vehicle platform 41, realizing the core function of the frame load-bearing mechanism in the above scheme.

[0071] In one specific embodiment, when the vehicle carrier 41, carrying a 1.8-ton vehicle, is lifted from the suspended position onto the support frame 1, at the instant the vehicle carrier 41 contacts the frame, the lifting chain assembly 422 changes from a state bearing approximately 2 tons of tension to a slack state. The second motor 421 and the transmission system are completely unloaded, no longer needing to provide holding torque, greatly reducing energy consumption and mechanical stress, and effectively extending the service life of the lifting system.

[0072] In some embodiments, the lifting chain assembly 422 includes: a drive sprocket, rotatably mounted on the transverse support 2 and connected to the output end of the second motor 421; two lifting sprockets, respectively fixed on both sides of the axial direction of the drive sprocket; and two lifting chains, respectively meshing with the two lifting sprockets, with one end of each lifting chain connected to a cantilever bracket 43.

[0073] In this invention, the lifting chain assembly 422 includes a drive sprocket, two lifting sprockets, and two lifting chains. The drive sprocket is rotatably mounted on the transverse support 2 and is connected to the output end of the second motor 421. The two lifting sprockets are fixedly mounted on both axial sides of the drive sprocket, and the two lifting chains mesh with the two lifting sprockets respectively. One end of each lifting chain is connected to the cantilever bracket 43. The dual-chain synchronous lifting mechanism ensures high stability and high load-bearing capacity during the lifting process of the cantilever bracket 43.

[0074] Specifically, the drive sprocket rotates under the drive of the second motor 421, synchronously driving two lifting chains through two axially arranged lifting sprockets to achieve synchronous lifting of both sides of the cantilever bracket 43. The dual-chain design evenly distributes the load to the two support points of the cantilever bracket 43, avoiding structural stress concentration that may be caused by single-point load-bearing. The synchronous transmission mechanism ensures that the lifting speed of the chains on both sides is completely consistent, preventing the cantilever bracket 43 from tilting or twisting during the lifting process.

[0075] In some embodiments, a charging gun 5 is provided on the edge of the vehicle platform 41 and / or on the support frame 1, and the position of the charging gun 5 is adapted to the position of the vehicle charging port.

[0076] In this invention, a charging gun 5 is provided on the edge of the vehicle carrier plate 41 and on the support frame 1, and the position of the charging gun 5 is adapted to the position of the vehicle's charging port. This integrated charging function provides a unified parking and charging service, greatly enhancing convenience for electric vehicle users and improving the functional value and market competitiveness of the parking equipment.

[0077] Specifically, the location of the charging gun 5 has been carefully designed, taking into account the distribution characteristics of charging ports for mainstream electric vehicle models. Whether the vehicle is parked on the upper vehicle platform 41 or the lower support frame 1, it can be easily connected for charging. The charging gun 5 adopts a flexible connection method, which can adapt to slight differences in the location of charging ports for different vehicle models, ensuring the reliability and convenience of the charging connection.

[0078] In related technologies, parking equipment and charging facilities are usually installed separately. Users need to park first and then find a charging station to charge, which is cumbersome and takes up more space. Separate installations may also lead to mismatches between parking spaces and charging station locations, affecting ease of use. However, in this embodiment, the integrated design of the charging function and parking equipment simplifies the user's operation process, achieving a convenient experience of charging while parking. The integrated design also saves space and improves the utilization efficiency of the facilities, making it particularly suitable for the market demand of the rapid popularization of electric vehicles, and adding an important value-added service function to the parking equipment.
