Technical Field

[0001] This invention belongs to the field of vertical circulation parking equipment, and relates to the power transmission technology of vertical circulation parking equipment, particularly to a disc-type linear motor transmission mechanism and a vertical circulation mechanical parking equipment. Background Technology

[0002] Automated parking systems are mechanical devices used for storing and retrieving vehicles. They are widely used due to their advantages such as small footprint and large storage capacity.

[0003] Vertical circulation parking systems are a common type of automated parking system. The transmission mechanism that drives the car bays (used for parking vehicles) in a vertical circulation manner typically employs complex structures such as multi-stage gears, chains, or belts. This results in a large number of parts and high assembly precision requirements, making the overall system cumbersome and complex. Furthermore, due to its complex structure, daily maintenance and troubleshooting require specialized techniques and tools, making disassembly and adjustment tedious, and maintenance difficult and time-consuming. Moreover, many transmission components are prone to wear, loosening, and fatigue fracture during long-term operation, leading to a high overall failure rate and severely impacting the reliability and continuous operational stability of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a novel disc-type linear motor transmission mechanism and a vertical circulation mechanical parking device. The device uses a linear motor drive, eliminating the need for traditional motors, sprockets, chains, and other transmission structures. This results in a simpler device structure, lower failure rate, and easier maintenance, thus solving the problems existing in the aforementioned transmission mechanisms.

[0005] To achieve the above objectives, the present invention provides the following solution: On one hand, the present invention proposes a disc-type linear motor transmission mechanism, comprising: A circulating chain is used to be tractably mounted on a machine frame; at least one side of the circulating chain is provided with a set of pulleys, the set of pulleys including a plurality of pulleys spaced apart along the circulating chain; A drive shaft assembly includes a drive shaft and a dial mounted on the drive shaft. The drive shaft is rotatably mounted on the equipment frame. The outer periphery of the dial is provided with a plurality of wheel grooves that mesh with the dial wheels. The dial and the dial wheel assembly correspond one-to-one. The drive shaft assembly is disposed at the top and / or bottom of the circulating chain. A linear motor includes a primary linear motor and a secondary linear motor that is inductively matched with the primary linear motor. The primary and secondary linear motors are located on the same side of the dial, and one of the primary and secondary linear motors is arranged in a ring on the side of the dial. The other of the primary and secondary linear motors is used to mount on the equipment frame. When the linear motor is energized, it can drive the dial to rotate in place, so as to use the dial to turn the dial wheel and drive the circulating chain to circulate.

[0006] In some embodiments, the linear motor secondary includes a multi-lobed arc-shaped sheet conductor plate arranged in a ring on the side of the dial; the linear motor primary is mounted on the equipment frame and is opposite to the linear motor secondary.

[0007] In some embodiments, the drive shaft assembly further includes a drive disk, which is disposed on the drive shaft and coaxial with the dial. The primary and secondary of the linear motor are located on the same side of the drive disk, and one of the primary and secondary of the linear motor is arranged in a ring on the side of the drive disk. The other of the primary and secondary of the linear motor is used to be mounted on the equipment frame. When the linear motor is energized, it can drive the drive disk to rotate in place, so as to use the dial to turn the dial wheel and drive the circulating chain to circulate.

[0008] In some embodiments, any one of the dials is rotatably mounted on the circulating chain via a wheel axle.

[0009] In some embodiments, any one of the chain pins of the circulating chain extends out of at least one side of the circulating chain, and the portion of the chain pin extending out of the circulating chain also serves as the axle for rotatably mounting the dial wheel.

[0010] In some embodiments, the disc-type linear motor transmission mechanism further includes a braking component that can brake the transmission shaft assembly after the linear motor is powered off.

[0011] In some embodiments, the braking assembly includes: A brake disc is mounted on the drive shaft and is coaxial with the dial. A brake caliper controlled by a hydraulic system is mounted on the equipment frame. The brake caliper can clamp the brake disc under the action of the hydraulic system to brake the drive shaft assembly.

[0012] On the other hand, the present invention proposes a vertical circulation mechanical parking device, including a frame and the aforementioned disc-type linear motor transmission mechanism; the frame includes a frame one and a frame two arranged symmetrically, and a set of circulation chains can be transmissively arranged on the inner sides of both the frame one and the frame two; the transmission shaft group is disposed between the frame one and the frame two, and the two ends of the transmission shaft are rotatably connected to the frame one and the frame two respectively; the circulation chain is provided with the derailleur group only on its inner side, and the derailleur on the same transmission shaft is matched and corresponds one-to-one with the circulation chain, and the derailleur is located on the inner side of the corresponding circulation chain.

[0013] In some embodiments, when the linear motor is provided only between the dial and the stand: the linear motor is provided on at least one side of the dial; both ends of the drive shaft are provided with the braking assembly, and the braking assembly is located outside the first frame and the second frame. After the linear motor is de-energized, at least one of the braking assemblies at both ends can be activated to brake the drive shaft assembly according to the load.

[0014] In some embodiments, when the linear motor is provided only between the drive disk and the upright: the linear motor is provided on at least one side of the drive disk; the drive disk is provided at at least one end of the transmission shaft, and the drive disk is located inside the dial; the braking assembly is provided at both ends of the transmission shaft, and the braking assembly is located outside the first frame and the second frame, so that after the linear motor is de-energized, at least one of the braking assemblies at both ends can be activated to brake the transmission shaft assembly according to the load.

[0015] In some embodiments, when the linear motor is provided only between the drive disk and the upright: the linear motor is provided on at least one side of the drive disk; the drive disk is provided at at least one end of the transmission shaft, and the drive disk is located outside the first frame and / or the second frame; the braking assembly is provided at both ends of the transmission shaft, and the braking assembly is located inside the first frame and the second frame, so that after the linear motor is de-energized, at least one of the braking assemblies at both ends can be activated to brake the transmission shaft assembly according to the load.

[0016] In some embodiments, the vertical circulation mechanical parking equipment further includes multiple compartments for parking vehicles; the multiple compartments are arranged around the outer periphery of the circulation chain and are all engaged with the movable guide of the upright frame, and any one of the compartments is connected to the circulation chain to perform vertical circulation under the action of the circulation chain.

[0017] In some embodiments, any one of the carriages is a pallet or a car.

[0018] The present invention achieves the following technical effects compared to the prior art: This invention uses linear motors to drive the equipment, eliminating the need for traditional motors, sprockets, and other transmission systems. This results in a simpler equipment structure, easier maintenance, and a lower failure rate. Because there is no traditional transmission mechanism, the linear motor operates more efficiently, is more energy-saving, and produces less noise. Furthermore, depending on the equipment load, power can be supplied to the primary motor of one side of the dial or drive plate, or to the primary motors of both sides simultaneously, which helps reduce equipment energy consumption.

[0019] In addition, using a dial to drive a rotating wheel to drive the circulating chain has the following advantages: (i) Each time the chain is turned, it advances precisely by a fixed pitch, which helps to accurately control the chain's stroke and improve the position transmission accuracy of loads such as carriages.

[0020] (ii) When the dial rotates, it can continuously move the dial wheel. The mechanical meshing structure formed by the groove of the dial and the dial wheel can effectively limit the inertial slippage of the chain when it stops, thereby improving the stopping positioning accuracy of the load such as the carriage. At the same time, the self-locking property of the meshing structure between the dial 32 and the dial wheel 2 can be used to prevent the load from falling or shifting, thus enhancing safety.

[0021] (III) The dial and dial wheel have a simple structure, low maintenance cost, and are very durable in low-speed heavy-load environments. They can withstand large starting torque and impact load, thus improving the reliability of equipment operation.

[0022] (iv) The circulating chain is generally installed in the chain guide rail of the upright. The chain runs along the fixed track under the drive of the pulley, which reduces the swing and wear of the chain during operation.

[0023] Vertical circulation mechanical parking equipment includes the aforementioned disc-type linear motor transmission mechanism and possesses all the characteristics of the aforementioned disc-type linear motor transmission mechanism, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] One of the objectives of this invention is to provide a disc-type linear motor transmission mechanism applicable to vertical circulation parking equipment. It uses a linear motor to drive the equipment, eliminating the need for traditional transmission structures such as motors, sprockets, and chains. The equipment structure is simpler, the failure rate is lower, and maintenance is more convenient, thus solving the problems existing in the current transmission mechanism.

[0029] Another object of the present invention is to provide a vertical circulation mechanical parking device comprising the above-mentioned disc-type linear motor transmission mechanism.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a disc-type linear motor transmission mechanism 100, which is essentially a vertical circulating power transmission mechanism. It mainly includes a circulating chain 1, a transmission shaft assembly 3, and a linear motor 4. The circulating chain 1 is rotatably mounted on a device frame, which includes, but is not limited to, the frame of a vertical circulating mechanical parking device, and can be flexibly changed according to the application of the transmission mechanism. At least one side of the circulating chain 1 is provided with a pulley assembly, which includes multiple pulleys 2 spaced apart along the circulating chain 1. Each pulley 2 has the same size and is preferably equidistant along the circulating chain 1 to ensure the stability of the chain transmission. The transmission shaft assembly 3 includes a transmission shaft 31 and a dial 32 mounted on the transmission shaft 31. The transmission shaft 31 is rotatably mounted on the device frame and vertically passes through the circulating chain 1. The transmission shaft 31 mainly serves as the mounting carrier and torque transmission mechanism for the dial 32. The outer periphery of the dial 32 is provided with multiple grooves 321 that mesh with the pulleys 2. The dial 32 corresponds one-to-one with the dial wheel assembly. That is, if the aforementioned dial wheel assembly is provided on both sides of the circulating chain 1, a dial 32 can be provided on each side of the circulating chain 1. If the aforementioned dial wheel assembly is provided on only one side of the circulating chain 1, a dial 32 can be provided on only one side of the circulating chain 1 to match the dial wheel assembly. In practical applications, the top and / or bottom of the circulating chain 1 are equipped with a drive shaft assembly 3. That is, the top and bottom of the circulating chain 1 can be equipped with a drive shaft assembly 3 and a linear motor 4 at the same time, or a drive shaft assembly 3 and a linear motor 4 can be provided at only one position at the top or bottom. The linear motor 4 includes a primary linear motor 41 and a secondary linear motor 42 that is inductively matched with the primary linear motor 41. The primary linear motor 41 and the secondary linear motor 42 in the same linear motor 4 are located on the same side of the dial 32, and one of the primary linear motor 41 and the secondary linear motor 42 is arranged in a ring on the side of the dial 32. The other of the primary linear motor 41 and the secondary linear motor 42 is used to be mounted on the equipment frame. When the linear motor 4 is energized, it can drive the dial 32 to rotate in place, so as to use the dial 32 to turn the dial wheel 2 and drive the circulating chain 1 to circulate.

[0032] The circulating chain 1 is a mature existing technology in vertical circulating parking equipment. It mainly consists of inner chain plates, outer chain plates, transition chain plates, triangular plates, sleeves, rollers, etc., which will not be described in detail here. Different loads can be installed on the circulating chain 1 according to different application scenarios to achieve vertical circulating drive of the load. Available loads include, but are not limited to, the vehicle body.

[0033] In some feasible implementations, the grooves 321 on the outer periphery of the dial 32 are evenly spaced. For example... Figure 2 As shown, any one of the grooves 321 is an arc-shaped groove that fits the outer diameter of the dial wheel 2. Each groove 321 can only accommodate a single dial wheel 2 at a time. The meshing relationship between the dial wheel 2 and the groove 321 is shown in the figure. Figure 2 As shown. The portion between any two adjacent grooves 321 is the tooth 322 of the dial 32. When a groove 321 is nested and engaged with the dial 2, the dial 2 can be turned by the tooth 322 that is adjacent to the groove 321 until the dial 2 is separated from the groove 321.

[0034] The circulating chain 1 is preferably configured as a closed-loop structure resembling a running track, with rounded ends (i.e., arc-shaped top and bottom) and a straight middle. The dial 32 is located at the arc-shaped position of the circulating chain 1, and the portions of the circulating chain 1 on both sides of the dial 32 are symmetrical. The outer diameter of the dial 32, the layout and number of grooves 321, and the spacing of the pulleys 2 on the circulating chain 1 determine whether the dial 32 engages with the pulleys 2 one by one (i.e., each time it only engages with the pulley 2 at the bottom or top via one groove 321) or whether it can engage synchronously with two symmetrically positioned pulleys 2. Figure 2 and Figure 3 As shown, the dial 32 utilizes two spaced and symmetrical grooves 321 to synchronously engage with two dial wheels 2, which are driven to the bottom or top respectively. By using the method of synchronously engaging the dial 32 with the two symmetrical dial wheels 2, the stability and reliability of the dial 32 driving the chain cyclic transmission can be improved, making the equipment using this transmission mechanism operate more smoothly.

[0035] In some feasible implementations, the dial 32 is coaxial with the drive shaft 31, and the dial 32 is fitted onto the drive shaft 31. This can be achieved by means of welding, key connection, flange connection, or other methods to fix the dial 32 to the drive shaft 31, thereby realizing synchronous rotation of the two.

[0036] In some feasible implementations, the linear motor secondary 42 is preferably mounted on the dial 32, while the linear motor primary 41 is mounted on the equipment frame. It is noted that the mounting position of the linear motor primary 41 avoids the transmission path of the circulating chain 1 to prevent interference with the circulating transmission of the circulating chain 1.

[0037] Specifically, the linear motor secondary 42 includes a multi-lobed arc-shaped sheet conductor plate 421, which is arranged in a ring on the side of the dial 32. Each adjacent pair of arc-shaped sheet conductor plates 421 are seamlessly joined, forming a closed ring coaxial with the dial 32. The linear motor primary 41 can be mounted on the equipment frame via a motor bracket, or directly mounted on the corresponding crossbeam of the frame. The linear motor primary 41 is opposite to and adjacent to the linear motor secondary 42. Both the motor bracket and the crossbeam should avoid the transmission path of the circulating chain 1 to prevent interference with its cyclic transmission. The arc-shaped sheet conductor plate 42 is fixed to the dial 32 using methods including, but not limited to, screw fixing.

[0038] The linear motor 4 is a device that directly converts electrical energy into linear motion mechanical energy. Its core working principle is based on electromagnetic induction and magnetic field interaction, eliminating the need for intermediate transmission mechanisms such as gears and lead screws. The primary winding 41 of the linear motor used in this solution refers to the electromagnetic component fixedly mounted on the equipment frame to generate an alternating magnetic field, functioning similarly to the "stator" in traditional rotary and linear motors. The secondary winding 42 refers to the conductive or magnetic component directly fixed on the dial 32 and positioned opposite the primary winding 41, functioning similarly to the "rotor" in traditional rotary and linear motors. In actual installation, a small air gap exists between each pair of primary and secondary windings 41 and 42, directly generating linear thrust through magnetic field interaction. The primary winding 41 typically includes three-phase AC windings and an iron core (with iron core type) or only windings (without iron core type). After symmetrical three-phase AC current is applied, a traveling wave magnetic field moving in a linear direction is generated in the air gap. The direction of movement of the traveling wave magnetic field is determined by the current phase sequence, and the speed (synchronous speed) is determined by the power supply frequency and pole pitch. The linear motor secondary 42 adopts an induction-type secondary structure. Each of its arc-shaped sheet conductor plates 421 can be made of conductive materials such as aluminum or copper. When the traveling wave magnetic field cuts the secondary conductor, eddy currents are generated inside the secondary according to Faraday's law of electromagnetic induction. These eddy currents interact with the traveling wave magnetic field, generating electromagnetic thrust according to the Lorentz force law (F = B × I × L), driving the secondary to move. The linear motor 4 used in this embodiment is existing technology. It transforms the traditional rotary drive that requires an intermediate conversion mechanism into a direct electromagnetic drive, realizing the integration of the power source and the execution component. It has advantages such as simplified structure, low failure rate, and low energy consumption.

[0039] In some feasible implementations, each dial 32 may have the aforementioned linear motor 4 installed on only one side, or linear motors 4 may be arranged on both sides with the same structure. When linear motors 4 are arranged on both sides, one of the linear motors 4 on both sides or both linear motors 4 can be driven or started simultaneously according to the actual load size, so as to realize load adaptive drive, with various modes and flexible applications. Especially when the load is small, driving only one of the linear motors 4 on both sides can achieve the effect of cost reduction and energy saving.

[0040] Each dial 2 is driven synchronously with the circulating chain 1. In some feasible embodiments, any dial 2 is rotatably mounted on the circulating chain 1 via axle 21, and each dial 2 can rotate around its corresponding axle 21. In other embodiments, the dial 2 can also be fixedly mounted, i.e., the dial 2 cannot rotate. This design will accelerate the wear of the dial 32 and is prone to jamming during rotation. Therefore, in this embodiment, it is preferred that the dial 2 be rotatably mounted on the circulating chain 1.

[0041] In some feasible implementations, the axle 21 can be directly mounted and fixed to the chain plate 11 of the circulating chain 1. The mounting and fixing methods include, but are not limited to, welding. The derailleur 2 is rotatably mounted on the axle 21 via a bearing, so that the derailleur 2 rotates around the axle 21. To simplify the structure of the transmission mechanism and improve the overall structural integration and simplicity of the transmission mechanism, it is preferable that the pin of any chain plate of the circulating chain 1 extends out of at least one side of the circulating chain 1. The part of the chain plate pin extending out of the circulating chain 1 can also serve as the axle 21 for rotatably mounting the derailleur 2. In practical applications, if the derailleur group is only set on one side of the circulating chain 1, the chain plate pin only needs to extend out of one side of the circulating chain 1. If the derailleur group is set on both sides of the circulating chain 1, the chain plate pin extends out of the circulating chain 1 on both sides for mounting the derailleur 2 located on both sides of the circulating chain 1. The chain plate pin is a common component in the circulating chain 1. It is mainly used to connect the opposite outer chain plate and inner chain plate, and at the same time realize the hinge of adjacent chain plates. This is a well-known prior art in the field, and will not be described in detail here.

[0042] In some feasible implementations, the disc-type linear motor drive mechanism 100 is also equipped with a control system, which includes, but is not limited to, mature control mechanisms such as PLCs. The control system is communicatively connected to the aforementioned linear motor 4 to control the power supply to and from the linear motor 4, thereby controlling the start / stop and operating mode of the linear motor 4.

[0043] Under the control system, the linear motor secondary 42 rotates, driving the dial 32 to rotate synchronously, which in turn drives the circulating chain 1 to rotate cyclically. After the linear motor 4 is de-energized, the braking assembly can be used to brake the drive shaft, thereby braking the entire transmission mechanism, stopping the transmission mechanism from operation and keeping it stationary.

[0044] The equipment is driven by linear motors, eliminating the need for traditional motors, sprockets, and other transmission systems. This results in a simpler structure, easier maintenance, and a lower failure rate. Because there is no traditional transmission mechanism, the linear motor operates more efficiently, is more energy-saving, and produces less noise. Furthermore, depending on the equipment load, power can be supplied to the primary motor on one side of the dial or to both primary motors simultaneously, further reducing energy consumption.

[0045] Meanwhile, driving the circulating chain 1 through the dial 32 to move the dial wheel 2 also has the following advantages: (i) Each time the chain is turned, it advances precisely by a fixed pitch, which helps to accurately control the chain's stroke and improve the position transmission accuracy of loads such as carriages.

[0046] (ii) When the dial rotates, it can continuously move the dial wheel. The mechanical meshing structure formed by the groove of the dial and the dial wheel can effectively limit the inertial slippage of the chain when it stops, thereby improving the stopping positioning accuracy of the load such as the carriage. At the same time, the self-locking property of the meshing structure between the dial 32 and the dial wheel 2 can be used to prevent the load from falling or shifting, thus enhancing safety.

[0047] (III) The dial and dial wheel have a simple structure, low maintenance cost, and are very durable in low-speed heavy-load environments. They can withstand large starting torque and impact load, thus improving the reliability of equipment operation.

[0048] (iv) The circulating chain is generally installed in the chain guide rail of the upright. The chain runs along the fixed track under the drive of the pulley, which reduces the swing and wear of the chain during operation.

[0049] Example 2 like Figure 4 and Figure 5 As shown, this embodiment provides a disc-type linear motor transmission mechanism 100. Based on embodiment 1, the transmission shaft assembly 3 of this embodiment further includes a drive disk 33, which is disposed on the transmission shaft 31 and coaxial with the dial 32.

[0050] The drive disc 33 is a disc structure. The drive disc 33 is mounted on the outside of the transmission shaft 31 and is fixed to the transmission shaft 31 by means of welding, key connection, flange connection and other methods, so as to realize the synchronous rotation of the two.

[0051] Because of the presence of the drive disk 33, compared to embodiment 1, this embodiment places the linear motor 4 between the stand and the drive disk 33, and the dial 32 does not have a linear motor secondary 42.

[0052] Specifically, the primary motor 41 and the secondary motor 42 of the same linear motor 4 are located on the same side of the drive disk 33, and one of the primary motor 41 and the secondary motor 42 is arranged in a ring on the side of the drive disk 33, while the other of the primary motor 41 and the secondary motor 42 is used to be mounted on the equipment frame. When the linear motor 4 is powered on, it can drive the drive disk 33 to rotate in place. The drive disk 33 drives the transmission shaft 31 and the dial 32 to rotate synchronously, and then the dial 32 can be used to turn the dial wheel 2 to drive the circulating chain 1 to circulate.

[0053] The linear motor secondary 42 includes a multi-lobed arc-shaped sheet conductor plate 421, which is arranged in a ring on the side of the drive disk 33. Each adjacent pair of arc-shaped sheet conductor plates 421 are seamlessly joined, forming a closed ring that is coaxial with both the drive disk 33 and the dial 32. The linear motor primary 41 can be mounted on the equipment frame via a motor bracket, or directly mounted on the corresponding crossbeam of the frame. The linear motor primary 41 is opposite to and adjacent to the linear motor secondary 42. Both the motor bracket and the crossbeam should avoid the transmission path of the circulating chain 1 to prevent interference with its cyclic transmission. The arc-shaped sheet conductor plate 42 is fixed to the drive disk 33 by methods including, but not limited to, screw fixing.

[0054] The linear motor 4 is a device that directly converts electrical energy into linear motion mechanical energy. Its core working principle is based on the interaction of electromagnetic induction and magnetic fields, eliminating the need for intermediate transmission mechanisms such as gears and lead screws. The primary winding 41 of the linear motor used in this solution refers to the electromagnetic component fixedly mounted on the equipment frame to generate an alternating magnetic field, functioning similarly to the "stator" in traditional rotary and linear motors. The secondary winding 42 refers to the conductive or magnetic component directly fixed on the drive disk 33 and positioned opposite the primary winding 41, functioning similarly to the "rotor" in traditional rotary and linear motors. In actual installation, a small air gap exists between each pair of primary and secondary windings 41 and 42, directly generating linear thrust through magnetic field interaction. The primary winding 41 typically includes three-phase AC windings and an iron core (with iron core type) or only windings (without iron core type). After symmetrical three-phase AC current is applied, a traveling wave magnetic field moving in a linear direction is generated in the air gap. The direction of movement of the traveling wave magnetic field is determined by the current phase sequence, and the speed (synchronous speed) is determined by the power supply frequency and pole pitch. The linear motor secondary 42 adopts an induction-type secondary structure. Each of its arc-shaped sheet conductor plates 421 can be made of conductive materials such as aluminum or copper. When the traveling wave magnetic field cuts the secondary conductor, eddy currents are generated inside the secondary according to Faraday's law of electromagnetic induction. These eddy currents interact with the traveling wave magnetic field, generating electromagnetic thrust according to the Lorentz force law (F = B × I × L), driving the secondary to move. The linear motor 4 used in this embodiment is existing technology. It transforms the traditional rotary drive that requires an intermediate conversion mechanism into a direct electromagnetic drive, realizing the integration of the power source and the execution component. It has advantages such as simplified structure, low failure rate, and low energy consumption.

[0055] In some feasible implementations, on the same drive shaft 31, the number of drive discs 33 and dials 32 are preferably the same and arranged in a one-to-one correspondence, that is, a drive disc 33 is provided on the side of each dial 32.

[0056] Each drive disk 33 may have the aforementioned linear motor 4 installed on only one side, or linear motors 4 may be arranged on both sides with the same structure. When linear motors 4 are arranged on both sides, one of the linear motors 4 on both sides or both linear motors 4 can be driven or started simultaneously according to the actual load size, so as to realize load adaptive drive, with various modes and flexible applications. Especially when the load is small, driving only one of the linear motors 4 on both sides can achieve the effect of cost reduction and energy saving.

[0057] Example 3 like Figures 1-9 As shown, this embodiment provides a disc-type linear motor transmission mechanism 100, which is further provided with a braking component 5 based on embodiment 1 or 2. The braking component 5 can brake the transmission shaft assembly 3 after the linear motor 4 is powered off.

[0058] In some feasible implementations, the braking assembly 5 includes, but is not limited to, block brakes, band brakes, disc brakes, and drum brakes. Taking a disc brake as an example, it includes a brake disc 51 and a brake caliper 52 controlled by a hydraulic system. The brake disc 51 is mounted on the drive shaft 31 and coaxial with the dial 32. The brake caliper 52 is mounted on the equipment stand. The brake caliper 52 can clamp the brake disc 51 from both the inside and outside under the action of the hydraulic system, so as to generate braking by using friction elements (brake pads) to axially clamp the brake disc 51 from both sides, thereby achieving the purpose of braking the drive shaft assembly 3.

[0059] Disc brakes are a mature braking technology, and their specific structure and functional principles will not be elaborated here.

[0060] The drive shaft 31 may be equipped with a braking assembly 5 at only one end, or it may be equipped with a braking assembly 5 at both ends.

[0061] In some feasible implementations, the preferred connection methods between the brake disc 51 and the drive shaft 31 include, but are not limited to, welding, key connection, flange connection and fixing, so as to achieve synchronous rotation of the two.

[0062] In some feasible implementations, in the same group of braking components 5, a brake disc 51 may be equipped with multiple brake calipers 52 at the same time. The multiple brake calipers 52 are distributed on the outer periphery of the brake disc 51 and are evenly spaced along the circumferential distance of the brake disc 51.

[0063] Example 4 like Figures 1-3 As shown, this embodiment provides a vertical circulation mechanical parking device 200, including a frame 6 and a disc-type linear motor transmission mechanism 100 of Embodiment 1. The frame 6 includes symmetrically arranged frame one 61 and frame two 62. Both frame one 61 and frame two 62 are provided with chain guide rails on their inner surfaces. A set of circulating chains 1 can be transmissively installed in the chain guide rails of both frame one 61 and frame two 62. The chain guide rails are used to install the circulating chains 1 and to position and guide the transmission of the circulating chains 1. The structure of the chain guide rails and the assembly method of the chain guide rails and the circulating chains 1 are conventional prior art in existing vertical circulation mechanical parking devices, and will not be described in detail here.

[0064] The drive shaft assembly 3 is located between the bottom of frame one 61 and frame two 62. The two ends of the drive shaft 31 are rotatably connected to frame one 61 and frame two 62 respectively, specifically through bearings for rotatable engagement with frame one 61 and frame two 62. The circulating chain 1 has a set of dial wheels only on its inner side. The dials 32 on the same drive shaft 31 are matched one-to-one with the circulating chain 1, that is, there are two dials 32 on the drive shaft 31. The two dials 32 are arranged close to the two ends of the drive shaft 31 and are located on the inner side of the corresponding circulating chain 1, and are arranged adjacent to the corresponding circulating chain 1 to ensure that the dials 32 can effectively mesh with the dial wheels 2 on the circulating chain 1.

[0065] In practical applications, there is a certain gap between the corresponding dial 32 and the circulating chain 1 to avoid contact and friction between them.

[0066] In some feasible implementations, a linear motor 4 is provided on at least one side of the dial 32; both ends of the drive shaft 31 are provided with braking components 5, and the braking components 5 are located outside the frame 1 61 and the frame 2 62. After the linear motor 4 is de-energized, at least one of the braking components 5 at both ends can be activated to brake the drive shaft assembly 3 according to the load.

[0067] Braking assembly 5 includes, but is not limited to, block brakes, band brakes, disc brakes, and drum brakes. Taking a disc brake as an example, it includes a brake disc 51 and a brake caliper 52 controlled by a hydraulic system. The brake disc 51 is mounted on the drive shaft 31 and is coaxial with the dial 32. The brake caliper 52 is mounted on the equipment stand. Under the action of the hydraulic system, the brake caliper 52 can clamp the brake disc 51 from both the inside and outside, so as to generate braking by using friction elements (brake pads) to axially clamp the brake disc 51 from both sides, thereby achieving the purpose of braking the drive shaft assembly 3.

[0068] Disc brakes are a mature braking technology, and their specific structure and functional principles will not be elaborated here.

[0069] The connection methods between the drive shaft 31 and the brake discs 51 at both ends include, but are not limited to, welding, key connection, flange connection and fixing, so as to achieve synchronous rotation of the two.

[0070] In some feasible implementations, within the same group of braking components 5, a single brake disc 51 may be equipped with multiple brake calipers 52 simultaneously. These multiple brake calipers 52 are distributed around the outer periphery of the brake disc 51 and are evenly spaced along the circumferential direction of the brake disc 51. For example... Figure 1 and Figure 2 The diagram shown is a schematic of a brake disc 51 with two brake calipers 52 configured simultaneously.

[0071] In some feasible implementations, the linear motor secondary 42 is mounted on the dial 32, while the linear motor primary 41 is mounted on frame one 61 and frame two 62. It is noted that the mounting position of the linear motor primary 41 avoids the transmission path of the circulating chain 1 to prevent interference with the circulating transmission of the circulating chain 1.

[0072] Specifically, the linear motor secondary 42 includes a multi-lobed arc-shaped sheet conductor plate 421, which is arranged in a ring on the side of the dial 32. Each adjacent pair of arc-shaped sheet conductor plates 421 are seamlessly joined, forming a closed ring coaxial with the dial 32. The linear motor primary 41 can be mounted on frame one 61 and frame two 62 via a motor bracket, or directly mounted on the upright beam 63 of frame one 61 and frame two 62. The linear motor primary 41 is opposite to and adjacent to the linear motor secondary 42. Both the motor bracket and the upright beam 63 should avoid the transmission path of the circulating chain 1 to prevent interference with the circulating transmission of the circulating chain 1. The arc-shaped sheet conductor plate 421 is fixed to the dial 32 by methods including, but not limited to, screw fixing.

[0073] In some feasible implementations, each dial 32 may have the aforementioned linear motor 4 installed on only one side, or linear motors 4 may be arranged on both sides with the same structure. When linear motors 4 are arranged on both sides, one of the linear motors 4 on both sides or both linear motors 4 can be driven or started simultaneously according to the actual load size, so as to realize load adaptive drive, with various modes and flexible applications. Especially when the load is small, driving only one of the linear motors 4 on both sides can achieve the effect of cost reduction and energy saving.

[0074] Example 5 like Figures 4-6 As shown, this embodiment provides a vertical circulation mechanical parking device 200, including a frame 6 and a disc-type linear motor transmission mechanism 100 as described in Embodiment 2. The frame 6 includes symmetrically arranged frame one 61 and frame two 62. Chain guide rails are provided on the inner surfaces of both frame one 61 and frame two 62. A set of circulating chains 1 can be tractively installed within the chain guide rails of both frame one 61 and frame two 62. The chain guide rails serve to install the circulating chains 1 and to position and guide the transmission of the circulating chains 1. The structure of the chain guide rails and the assembly method of the chain guide rails and the circulating chains 1 are conventional prior art in existing vertical circulation mechanical parking devices, and will not be described in detail here.

[0075] The drive shaft assembly 3 is located between the bottom of frame one 61 and frame two 62. The two ends of the drive shaft 31 are rotatably connected to frame one 61 and frame two 62 respectively, specifically through bearings for rotatable engagement with frame one 61 and frame two 62. The circulating chain 1 has a set of dial wheels only on its inner side. The dials 32 on the same drive shaft 31 are matched one-to-one with the circulating chain 1, that is, there are two dials 32 on the drive shaft 31. The two dials 32 are arranged close to the two ends of the drive shaft 31 and are located on the inner side of the corresponding circulating chain 1, and are arranged adjacent to the corresponding circulating chain 1 to ensure that the dials 32 can effectively mesh with the dial wheels 2 on the circulating chain 1.

[0076] In practical applications, there is a certain gap between the corresponding dial 32 and the circulating chain 1 to avoid contact and friction between them.

[0077] In some feasible implementations, braking components 5 are provided at both ends of the drive shaft 31, and the braking components 5 are located outside the frame 1 61 and the frame 2 62. After the linear motor 4 is de-energized, at least one of the braking components 5 at both ends can be activated to brake the drive shaft assembly 3 according to the load.

[0078] Braking assembly 5 includes, but is not limited to, block brakes, band brakes, disc brakes, and drum brakes. Taking a disc brake as an example, it includes a brake disc 51 and a brake caliper 52 controlled by a hydraulic system. The brake disc 51 is mounted on the drive shaft 31 and is coaxial with the dial 32. The brake caliper 52 is mounted on the equipment stand.

[0079] Disc brakes are a mature braking technology, and their specific structure and functional principles will not be elaborated here.

[0080] The connection methods between the drive shaft 31 and the brake discs 51 at both ends include, but are not limited to, welding, key connection, flange connection and fixing, so as to achieve synchronous rotation of the two.

[0081] In some feasible implementations, within the same group of braking components 5, a single brake disc 51 may be equipped with multiple brake calipers 52 simultaneously. These multiple brake calipers 52 are distributed around the outer periphery of the brake disc 51 and are evenly spaced along the circumferential direction of the brake disc 51. For example... Figure 4 and Figure 5 The diagram shown is a schematic of a brake disc 51 with two brake calipers 52 configured simultaneously.

[0082] In this embodiment, the linear motor 4 is only located between the drive disk 33 and the upright frame 6. For example... Figures 4-6As shown, the number of drive disks 33 and dials 32 is the same, and they are arranged in a one-to-one correspondence. That is, each dial 32 has a drive disk 33 on its inner side.

[0083] In some feasible implementations, the primary linear motor 41 and the secondary linear motor 42 of the same linear motor 4 are located on the same side of the drive disk 33, and one of the primary linear motor 41 and the secondary linear motor 42 is arranged in a ring on the side of the drive disk 33, while the other of the primary linear motor 41 and the secondary linear motor 42 is mounted on frame one 61 and frame two 62. When the linear motor 4 is powered on, it can drive the drive disk 33 to rotate in place. The drive disk 33 drives the transmission shaft 31 and the dial 32 to rotate synchronously, and then the dial 32 can be used to turn the dial wheel 2 to drive the circulating chain 1 to circulate.

[0084] Specifically, the linear motor secondary 42 includes a multi-lobed arc-shaped sheet conductor plate 421, which is arranged in a closed ring on the side of the drive disk 33. Each adjacent pair of arc-shaped sheet conductor plates 421 are seamlessly joined, and the resulting ring is coaxial with the drive disk 33 and the dial 32. The linear motor primary 41 can be mounted on the inner side of frame one 61 and frame two 62 via a motor bracket, or directly mounted on the corresponding upright beam 63 on the inner side of frame one 61 and frame two 62. The linear motor primary 41 is opposite to and adjacent to the linear motor secondary 42. Both the motor bracket and the upright beam 63 should avoid the transmission line of the circulating chain 1 to prevent interference with the circulating transmission of the circulating chain 1. The arc-shaped sheet conductor plate 421 is fixed to the drive disk 33 by means including, but not limited to, screw fixing.

[0085] Each drive disk 33 may have the aforementioned linear motor 4 installed on only one side, or linear motors 4 may be arranged on both sides with the same structure. When linear motors 4 are arranged on both sides, one of the linear motors 4 on both sides or both linear motors 4 can be driven or started simultaneously according to the actual load size, so as to realize load adaptive drive, with various modes and flexible applications. Especially when the load is small, driving only one of the linear motors 4 on both sides can achieve the effect of cost reduction and energy saving.

[0086] Example 6 like Figures 7-9As shown, this embodiment provides a vertical circulation mechanical parking device 200, including a frame 6 and a disc-type linear motor transmission mechanism 100 as described in Embodiment 2. The frame 6 includes symmetrically arranged frame one 61 and frame two 62. Chain guide rails are provided on the inner surfaces of both frame one 61 and frame two 62. A set of circulating chains 1 can be tractively installed within the chain guide rails of both frame one 61 and frame two 62. The chain guide rails serve to install the circulating chains 1 and to position and guide the transmission of the circulating chains 1. The structure of the chain guide rails and the assembly method of the chain guide rails and the circulating chains 1 are conventional prior art in existing vertical circulation mechanical parking devices, and will not be described in detail here.

[0087] The drive shaft assembly 3 is located between the bottom of frame one 61 and frame two 62. The two ends of the drive shaft 31 are rotatably connected to frame one 61 and frame two 62 respectively, specifically through bearings for rotatable engagement with frame one 61 and frame two 62. The circulating chain 1 has a set of dial wheels only on its inner side. The dials 32 on the same drive shaft 31 are matched one-to-one with the circulating chain 1, that is, there are two dials 32 on the drive shaft 31.

[0088] In practical applications, there is a certain gap between the corresponding dial 32 and the circulating chain 1 to avoid contact and friction between them.

[0089] In some feasible implementations, a braking assembly 5 is also provided on the drive shaft 31, and the braking assembly 5 is located between frame one 61 and frame two 62. After the linear motor 4 is de-energized, at least one of the two braking assemblies 5 can be activated to brake the drive shaft assembly 3 according to the load.

[0090] The braking assembly 5 includes, but is not limited to, block brakes, band brakes, disc brakes, and drum brakes. Taking a disc brake as an example, it includes a brake disc 51 and a brake caliper 52 controlled by a hydraulic system. The brake disc 51 is mounted on the drive shaft 31 and is coaxial with the dial 32. The brake caliper 52 is mounted on the stand 6.

[0091] Disc brakes are a mature braking technology, and their specific structure and functional principles will not be elaborated here.

[0092] In some feasible implementations, it is preferable that a braking assembly 5 is disposed inside each dial 32. The connection method between the brake disc 51 of the braking assembly 5 and the drive shaft 31 includes, but is not limited to, welding, key connection, flange connection and fixing, so as to achieve synchronous rotation of the two. The brake caliper 52 of the braking assembly 5 is disposed inside the first frame 61 and the second frame 62.

[0093] In some feasible implementations, within the same group of braking components 5, a single brake disc 51 may be equipped with multiple brake calipers 52 simultaneously. These multiple brake calipers 52 are distributed around the outer periphery of the brake disc 51 and are spaced apart along the circumference of the brake disc 51. For example... Figure 7 and Figure 8 The diagram shown is a schematic of a brake disc 51 with two brake calipers 52 configured simultaneously.

[0094] In this embodiment, the linear motor 4 is only located between the drive disk 33 and the upright frame 6. For example... Figures 7-9 As shown, the number of drive discs 33 and dials 32 is the same, and they are arranged in a one-to-one correspondence. Each dial 32 has a drive disc 33 on its outer side. Specifically, the two drive discs 33 can be arranged on the outer sides of frame one 61 and frame two 62, respectively.

[0095] In some feasible implementations, the primary linear motor 41 and the secondary linear motor 42 of the same linear motor 4 are located on the same side of the drive disk 33, and one of the primary linear motor 41 and the secondary linear motor 42 is arranged in a ring on the side of the drive disk 33, while the other of the primary linear motor 41 and the secondary linear motor 42 is mounted on frame one 61 and frame two 62. When the linear motor 4 is powered on, it can drive the drive disk 33 to rotate in place. The drive disk 33 drives the transmission shaft 31 and the dial 32 to rotate synchronously, and then the dial 32 can be used to turn the dial wheel 2 to drive the circulating chain 1 to circulate.

[0096] Specifically, the linear motor secondary 42 includes a multi-lobed arc-shaped sheet conductor plate 421, which is arranged in a ring on the side of the drive disk 33. Each adjacent pair of arc-shaped sheet conductor plates 421 are seamlessly joined, forming a closed ring coaxial with the drive disk 33 and the dial 32. The linear motor primary 41 can be mounted on the outside of frame one 61 and frame two 62 via a motor bracket, or directly mounted on the corresponding upright beam 63 on the outside of frame one 61 and frame two 62. The linear motor primary 41 is opposite to and adjacent to the linear motor secondary 42. Both the motor bracket and the upright beam 63 should avoid the transmission line of the circulating chain 1 to prevent interference with the circulating transmission of the circulating chain 1. The arc-shaped sheet conductor plate 421 is fixed to the drive disk 33 by means including, but not limited to, screw fixing.

[0097] Each drive disk 33 may have the aforementioned linear motor 4 installed on only one side, or linear motors 4 may be arranged on both sides with the same structure. When linear motors 4 are arranged on both sides, one of the linear motors 4 on both sides or both linear motors 4 can be driven or started simultaneously according to the actual load size, so as to realize load adaptive drive, with various modes and flexible applications. Especially when the load is small, driving only one of the linear motors 4 on both sides can achieve the effect of cost reduction and energy saving.

[0098] Example 7 like Figure 1 , Figure 4 and Figure 7 As shown, this embodiment provides a vertical circulation mechanical parking device 200, which, based on embodiments 4 to 6, is further provided with multiple carriages 7 for carrying and parking vehicles; the multiple carriages 7 are arranged around the outer periphery of the circulation chain 1 and are all in movable guide cooperation with the upright frame 6. Any carriage 7 is connected to the circulation chain 1 so as to perform vertical circulation under the driving action of the circulation chain 1 of the disc linear motor transmission mechanism 100.

[0099] In some feasible implementations, the structure of the carriage 7 is not limited, including but not limited to existing pallets (also known as "carriage platforms") or cars.

[0100] The assembly method of the carriage 7 on the frame 6 of the vertical circulation mechanical parking equipment 200 is existing technology; for specific structure, please refer to [reference needed]. Figure 1 , Figure 4 and Figure 7 This will not be elaborated upon here.

[0101] In addition to the embodiments described above, a linear motor 4 can also be configured only on the drive disk 33 or dial 32 on the side closest to frame one 61. The power of the linear motor 4 is transmitted to the circulating chain 1 on the side closest to frame two 62 via the dial 32 on that side, the drive shaft 31, and the dial 32 on the side closest to frame two 62, thereby enabling the equipment to operate. Similarly, a linear motor 4 can also be configured only on the drive disk 33 or dial 32 on the side closest to frame two 62. The power of the linear motor 4 is transmitted to the circulating chain 1 on the side closest to frame one 61 via the dial 32 on that side, the drive shaft 31, and the dial 32 on the side closest to frame one 61, thereby enabling the equipment to operate. In this invention, the drive shaft 31 only serves as a synchronous component and is not a primary load-bearing component.

[0102] The beneficial technical effects of the present invention are as follows: The equipment is driven by linear motors, eliminating the need for traditional motors, sprockets, and other transmission systems. This results in a simpler structure, easier maintenance, and a lower failure rate. Because there is no traditional transmission mechanism, the linear motor operates more efficiently, is more energy-saving, and produces less noise. Furthermore, depending on the equipment load, power can be supplied to the primary motor of one side of the dial or drive plate, or both primary motors can be powered simultaneously, further reducing energy consumption.
