Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an electromagnetic brake, a vertical rail assembly, and a garment care machine. Background Technology

[0002] Electromagnetic brakes are widely used in mechanical transmission systems for rapid braking in the event of power failure or emergencies. Traditional electromagnetic brakes often employ a single-sided brake pad design. While this design is simple in structure, it has significant drawbacks in practical use. A single-sided brake pad easily leads to uneven wear of the brake disc, resulting in uneven distribution of braking force, which in turn affects braking performance and service life. Furthermore, while some double-sided brakes have solved the problem of single-sided brake pads, their complex structure and high maintenance costs limit their widespread application.

[0003] In the application of vertical rail components, the cooperation between the drive belt and the slider is particularly critical. Under gravity, the slider constantly exerts a unidirectional tension on the drive belt due to gravity. However, in the event of a sudden power outage or power failure, the slider loses its driving force and will fall under its own weight, posing a serious safety hazard. To solve this problem, the applicant attempted to implement a limit brake on the drive belt. However, in scenarios where the drive belt rotates at high speeds, traditional limit brake devices struggle to accurately engage with the drive belt, resulting in unsatisfactory braking performance.

[0004] Publication No.: CN108799371A An electromagnetic brake for an external rotor motor includes a brake housing, an armature disc disposed on the rear end face of the brake housing, and a friction plate fixed to the rear end face of the brake housing via a connecting assembly. The friction disc is located between the armature disc and the friction plate. However, the electromagnetic coil is wound around the motor output shaft, making installation and use inconvenient, requiring a certain length for the motor output shaft, and the friction plate is a one-piece structure, necessitating replacement of the entire unit, resulting in high maintenance costs.

[0005] In summary, existing electromagnetic brakes have numerous shortcomings in structural design and practical application, failing to address issues such as poor braking performance, complex structure, and high maintenance costs. Furthermore, existing vertical rail components exhibit unsatisfactory braking performance, making it difficult to meet the requirements of high efficiency, stability, and safety. Therefore, a novel electromagnetic brake is urgently needed that can achieve efficient and balanced braking performance while maintaining a simple structure and low maintenance costs, particularly in applications involving high speeds and gravity, such as garment care machines, to ensure system safety and reliability. Summary of the Invention

[0006] In view of this, the present invention aims to provide an electromagnetic brake, a vertical rail assembly, and a garment care machine to solve the problems of poor braking effect, complex structure, and high maintenance cost.

[0007] The technical solution of this utility model is implemented as follows:

[0008] The primary objective of this invention is to disclose an electromagnetic brake, comprising:

[0009] The brake disc is connected to the output shaft of the motor.

[0010] Brake pad assemblies are disposed on both sides of the brake disc, and the brake pad assemblies include a first brake pad assembly and a second brake pad assembly.

[0011] A fixing plate connected to the motor housing, wherein the side of the fixing plate away from the motor housing is provided with a friction surface that mates with the first brake pad assembly;

[0012] A pressure plate that is axially movable and sleeved on the output shaft, wherein the side of the pressure plate adjacent to the brake disc is provided with a friction surface that cooperates with the second brake pad assembly;

[0013] Magnet storage base connected to the fixing plate via guide bolts;

[0014] An electromagnet embedded in the magnet storage base;

[0015] A return spring is sleeved on the guide bolt and located between the pressure plate and the magnet receiving base.

[0016] Furthermore, the first brake pad assembly includes multiple brake pads connected end to end in a ring structure. Each brake pad has a connecting hole at both ends for the guide bolt to pass through and fix the first brake pad assembly.

[0017] Furthermore, radial fins are provided on the side of the first brake pad assembly away from the brake disc to increase friction.

[0018] Furthermore, the first brake pad assembly and the second brake pad assembly have the same structure.

[0019] Furthermore, radial fins are provided on one side of the fixing plate adjacent to the first leather group or on one side of the pressure plate adjacent to the second leather group to increase friction.

[0020] Furthermore, the brake pad assembly, the fixing plate, and the pressure plate are provided with a tungsten carbide wear-resistant layer.

[0021] Furthermore, the electromagnet is disposed in the middle of the magnet storage base.

[0022] Furthermore, the brake disc is connected to the output shaft of the motor via a coupling.

[0023] The second objective of this invention is to disclose a vertical rail assembly that utilizes any of the aforementioned electromagnetic brakes, including a dual-output shaft motor. One shaft of the dual-output shaft motor is used to drive the transmission belt, and the other shaft is used to cooperate with the electromagnetic brake to apply braking force.

[0024] The third objective of this invention is to disclose a garment care machine that utilizes any of the aforementioned electromagnetic brakes and vertical rail components.

[0025] Compared with existing technologies, the motor brake, vertical rail assembly, and clothing handling device of this utility model have the following advantages:

[0026] 1. This utility model, by setting brake pads on both sides of the brake disc and using the bidirectional clamping of the fixing plate and the pressure plate, achieves the application of frictional force to the brake disc from both sides, which improves the braking torque, ensures a more uniform distribution of braking force, avoids the problem of uneven wear caused by unilateral braking, and also improves heat dissipation efficiency. Moreover, each component is set independently, the structure is simple, easy to assemble and replace, and the maintenance cost is low.

[0027] 2. This utility model uses a brake pad assembly with multiple brake pads connected in a ring structure, which allows for the replacement of damaged or worn brake pads individually, rather than having to replace the entire brake pad assembly. This reduces maintenance costs and resource waste, decreases the risk of brake failure due to overheating, and improves equipment safety.

[0028] 3. This utility model enhances heat dissipation and wear resistance by setting radial fins on the surface of the brake pad assembly and spraying a tungsten carbide wear-resistant layer, thereby extending the service life of the brake pad assembly and ensuring stability and reliability under long-term operation.

[0029] 4. This utility model adopts a dual-shaft motor, one shaft for driving the transmission belt and the other shaft for cooperating with the electromagnetic brake to achieve the braking function, which simplifies the mechanical structure of the vertical rail assembly, reduces energy loss in the energy transmission path, and improves the overall working efficiency.

[0030] 5. By using a novel electromagnetic brake and vertical rail assembly, this utility model enables the electromagnetic brake to be activated immediately in the event of a sudden power outage or other unforeseen circumstances, preventing the slider from falling due to gravity and ensuring the safety of the equipment and the user. It provides additional safety protection, especially in household appliances such as garment care machines. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model. Furthermore, descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0038] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0039] The first objective of this utility model is to disclose an electromagnetic brake, comprising:

[0040] Brake disc 1 is connected to the output shaft of the motor;

[0041] Brake pad assembly 2 is disposed on both sides of brake disc 1. Brake pad assembly 2 includes first brake pad assembly 201 and second brake pad assembly 202.

[0042] The fixing plate 3 connected to the motor housing has a friction surface on the side away from the motor housing that mates with the first brake pad assembly 201;

[0043] A pressure disc 4 is axially movable and sleeved on the output shaft. The side of the pressure disc 4 adjacent to the brake disc 1 is provided with a friction surface that cooperates with the second brake pad assembly 202.

[0044] Magnet storage base 6 is connected to the fixing plate 3 via guide bolt 5;

[0045] An electromagnet 7 is embedded in the magnet storage base 6;

[0046] A return spring 8 is fitted onto the guide bolt 5 and located between the pressure plate 4 and the magnet receiving base 6.

[0047] When the brake is engaged and the power is off, the return spring 8 pushes the pressure plate 4 to press the brake disc 1, causing the brake pads 2 on both sides to generate frictional braking force with the fixed plate 3 and the pressure plate 4 respectively.

[0048] When in the released state, i.e. when energized, the electromagnet 7 generates a magnetic attraction force, which overcomes the spring force and pulls the pressure plate 4 away from the brake plate 1, thus releasing the friction brake.

[0049] By combining the fixing plate 3, pressure plate 4, and brake disc 1, the pressure plate 4 moves during braking, and the fixing plate 3 and pressure plate 4 together clamp the brake disc 1, improving braking torque and heat dissipation efficiency. The brake disc 1 is designed with brake pads 2 on both sides, meaning the first brake pad group 201 and the second brake pad group 202 apply friction to the brake disc 1 from both sides, ensuring a more uniform distribution of braking force and avoiding uneven wear caused by single-sided brake pads. In the event of a sudden power outage or power failure, the return spring 8 pushes the pressure plate 4 to press the brake disc 1, achieving rapid braking. Compared to traditional complex designs, the magnet housing base 6, electromagnet 7, and return spring 8 are located on the side of the brake disc 1 away from the motor housing. The motor's output shaft is directly connected to the brake disc 1, reducing limitations on the length of the motor's output shaft and expanding the application range of the electromagnetic brake. The electromagnet 7 is located away from core components such as the motor, avoiding localized overheating that could affect other critical components. Furthermore, the overall structure is compact and simple, with each component independently set, eliminating the need for coil winding. This simple structure makes assembly and replacement easy, resulting in low maintenance costs.

[0050] Specifically, brake disc 1 is connected to the output shaft via a coupling.

[0051] As an intermediate connecting component, the coupling ensures efficient and smooth power transmission from the motor output shaft to the brake disc 1. It can compensate for axial, radial and angular installation errors to a certain extent, making the connection between the brake disc 1 and the motor output shaft more flexible, facilitating disassembly and reinstallation during maintenance and repair, reducing downtime and improving work efficiency.

[0052] This design simplifies the design and installation process, reduces the requirements for precise positioning, and makes the overall assembly simpler and faster. It can effectively reduce vibration and noise caused by assembly errors, thereby improving the operational stability and reliability of the entire electromagnetic brake system.

[0053] Preferably, the coupling can be one of the following: flexible coupling, diaphragm coupling, gear coupling, safety coupling, or bellows coupling.

[0054] Depending on the specific application of the electromagnetic brake, a suitable coupling type can be selected. For example, in applications requiring high precision, stability, and reliability, diaphragm couplings or bellows couplings can be chosen; while when facing potential overload risks, safety couplings can be selected. Each coupling has its unique function and advantages, and selecting the appropriate coupling can ensure efficient power transmission and improve the performance and safety of the entire system.

[0055] Specifically, the first brake pad assembly 201 includes multiple brake pads 203, which are connected end to end in a ring structure. Both ends of the brake pads 203 are provided with connecting holes for the guide bolts 5 to pass through and fix the first brake pad assembly 201. Radial fins are provided on the side of the first brake pad assembly 201 away from the brake disc 1 to increase friction.

[0056] Multiple brake pads 203 are connected end-to-end by bonding or welding, facilitating installation and disassembly. When maintenance or replacement is required, single or multiple brake pads 203 can be easily replaced without replacing the entire brake pad assembly 2, improving maintenance efficiency and reducing costs. The radial fins can be either protrusions or recesses relative to the brake pad assembly base surface. These radial fins can mate with the friction surfaces on the mounting plate. Compared to the mating of the brake pad assembly base surface and the friction surfaces, the radial fins create more contact points, thereby increasing the critical values ​​of static and sliding friction and significantly enhancing the overall friction.

[0057] Preferably, the friction surface on the fixed plate is also provided with radial fins. The radial fins of the friction surface can be protrusions relative to the base surface of the friction surface, or they can be recesses relative to the base surface of the friction surface. Furthermore, the radial fins of the brake pad assembly can even mechanically engage with the radial fins of the friction surface. This interlocking effect requires additional force to disengage, thereby significantly increasing the friction force.

[0058] The radial fin design increases the surface area of ​​the brake pad assembly 2 or the mounting plate, which is beneficial for heat dissipation. Especially under prolonged or high-intensity use, good heat dissipation helps maintain the stability of the braking system and extend its service life.

[0059] This design reduces the risk of localized overheating and wear, ensuring long-term stable braking performance. Damaged or worn brake pads 203 can be replaced individually instead of the entire brake pad assembly 2, which significantly reduces maintenance costs and resource waste, reduces the risk of brake failure due to overheating, and improves equipment safety.

[0060] Specifically, the first brake pad assembly 201 and the second brake pad assembly 202 have the same structure.

[0061] The first brake pad assembly 201 and the second brake pad assembly 202 with the same structure can ensure that the braking force applied to the brake disc 1 on both sides is uniform and consistent, avoiding the problem of uneven wear caused by unilateral braking, improving the overall braking effect, simplifying the design process of the entire electromagnetic brake, reducing the types of parts, thereby reducing design complexity and manufacturing costs. When replacement or maintenance is required, inventory management and spare parts preparation become simpler, because only one type of brake pad 203 needs to be stocked to meet the needs of both sets.

[0062] This design reduces the risk of failure due to excessive wear on one side, improves the reliability and durability of the system, and ensures that the brake pads on both sides have the same structure and consistent heat dissipation performance, thereby further ensuring the stable operating temperature of the entire braking system, preventing local overheating, facilitating large-scale production, reducing unit costs, enabling quick replacement by on-site technicians, reducing downtime, and improving the maintainability of the equipment.

[0063] Specifically, radial fins are provided on one side of the fixing plate 3 adjacent to the first brake pad 201 or on one side of the pressure plate 4 adjacent to the second brake pad 202.

[0064] Preferably, the friction surface on the pressure disc 4 is also provided with radial fins. The radial fins of the friction surface can be protrusions relative to the base surface of the friction surface, or they can be recesses relative to the base surface of the friction surface. Furthermore, the radial fins of the brake pad assembly can mechanically engage with the radial fins of the friction surface; this interlocking effect requires additional force to disengage, thus significantly increasing the frictional force. The radial fins increase the surface area of ​​the pressure disc 4, allowing heat to dissipate more quickly. When the frictional heat generated during braking is transferred to the pressure disc 4 through the second brake pad assembly 202, the fins between the second brake pad assembly 202 and the pressure disc 4 form a heat dissipation channel, effectively diffusing this heat into the surrounding environment. This not only enhances its own heat dissipation capacity but also indirectly improves the thermal environment inside the entire brake, significantly reducing the rate of material aging caused by overheating, ensuring long-term efficient braking, and extending the service life of the pressure disc 4, brake pad assembly 2, and other related components.

[0065] This design reduces the risk of failure due to overheating, improves the reliability and stability of the entire electromagnetic braking system, extends maintenance cycles, and reduces maintenance frequency and cost.

[0066] Specifically, four guide bolts 5 are provided, and the four guide bolts 5 are evenly arranged circumferentially on the magnet storage base 6.

[0067] The evenly distributed four guide bolts 5 ensure that the pressure plate 4 moves precisely along the axial direction. Each guide bolt 5 plays a guiding and supporting role, enabling the pressure plate 4 to maintain smooth movement during braking and release, avoiding deviation or jamming. The evenly distributed four guide bolts 5 provide multi-point support, increasing the rigidity and stability of the entire structure and preventing component damage or premature wear caused by local stress concentration.

[0068] This design improves stability and uniform force distribution, reduces friction and wear between components, simplifies the assembly process, and makes installation easier and faster.

[0069] Specifically, the surfaces of the brake pad assembly 2, the mounting plate 3, and the pressure plate 4 are provided with a tungsten carbide wear-resistant layer.

[0070] Because braking involves a significant amount of friction, especially in high-load or frequent braking applications, materials are prone to rapid wear. Adding a tungsten carbide wear-resistant layer can significantly extend the service life of these components, helping to protect critical components from environmental factors such as moisture and chemicals, further extending their lifespan and maintaining stable performance. The tungsten carbide coating also provides a more consistent coefficient of friction, reducing fluctuations in braking performance caused by uneven friction surfaces.

[0071] This setup enables the system to maintain high braking performance for a longer period of time, reduces replacement frequency and maintenance costs, and improves the reliability and stability of the entire electromagnetic brake system.

[0072] Specifically, the electromagnet 7 is positioned in the middle of the magnet storage base 6.

[0073] This layout maximizes the use of available volume within a limited space, making the entire brake structure more compact. This is especially important for equipment with strict size requirements, such as household appliances or small mechanical equipment.

[0074] The second objective of this invention is to disclose a vertical rail assembly that utilizes any of the aforementioned electromagnetic brakes, including a dual-output shaft motor. One shaft of the dual-output shaft motor is used to provide driving force for the movement of the vertical rail assembly, and the other shaft is connected to the electromagnetic brake for braking the vertical rail assembly in abnormal states such as power failure of the clothing handling device.

[0075] A dual-output-shaft motor is a specially designed electric motor with two output shafts, each of which can work independently or in concert. The two shafts are usually located at both ends of the motor and can output power simultaneously, allowing the motor to perform multiple functions or drive multiple components in different application scenarios.

[0076] Many garment care devices include a vertical rail assembly to guide the vertical movement of the horizontal rail assembly. This vertical rail assembly comprises a motor, drive shaft, drive belt, and lifting module. When the dual-output shaft motor is powered, one shaft drives the drive shaft, which in turn drives the drive belt, thus moving the lifting module. In the event of a sudden power outage or interruption, the electromagnetic brake activates, stopping the motor and ensuring the lifting module remains stationary, preventing it from falling under its own weight.

[0077] One shaft of the dual-output shaft motor drives the transmission belt to ensure the normal operation of the vertical rail assembly; the other shaft is dedicated to working with the electromagnetic brake for braking operations. Integrating drive and braking functions into a single motor simplifies the system structure. By using a dual-output shaft motor, independent control of drive and braking can be achieved, ensuring a rapid response and braking operation when needed. This improves the system's control accuracy and response speed. In the event of a sudden power outage or emergency, the electromagnetic brake can be activated immediately to prevent the lifting module from falling due to gravity, ensuring the safety of equipment and personnel.

[0078] This setup integrates drive and braking functions into a single motor, reducing energy loss in the transmission path and improving overall efficiency. Simultaneously, the reduced number of mechanical connection points lowers the likelihood of malfunctions and decreases the number of required mechanical parts, making the entire vertical rail assembly more compact and simple. This reduces installation complexity and cost, optimizing the overall size of the vertical rail assembly, making it suitable for installation in space-constrained environments, such as inside household appliances or other small mechanical devices.

[0079] The third objective of this invention is to disclose a garment care machine that utilizes any of the aforementioned electromagnetic brakes and vertical rail components.

[0080] The aforementioned electromagnetic brake can be applied to the power-off braking of the motor in a garment processing device. It can effectively achieve rapid braking of the motor, avoid other abnormal situations, improve the safety of the device, and has a simple and compact structure, saves space, is easy to install and maintain, and has a low cost.

[0081] By using the aforementioned vertical rail assembly, the garment care machine can achieve higher control precision and better performance during operation. For example, when a stop or deceleration is required, the electromagnetic brake responds quickly, providing immediate and smooth braking. In the event of a sudden power outage or other unforeseen circumstances, the electromagnetic brake activates immediately, stopping the vertical rail assembly and preventing the lifting module from falling due to gravity, thus ensuring the safety of the equipment and the user. The optimized braking system makes the garment care machine operate more smoothly, reducing noise and vibration, improving the user experience, reducing unnecessary energy consumption, improving overall energy efficiency, and lowering energy costs.

[0082] The integrated drive and braking design makes the overall structure of the garment care machine more compact, suitable for installation in limited spaces, meeting the requirements of modern home environments, and providing greater flexibility and adaptability.

[0083] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
