Description

Technical Field

[0001] This utility model relates to the field of braking system technology, and more specifically, to an electromagnetic braking system and a vehicle having the same. Background Technology

[0002] The braking system is an important component of a vehicle. Its function is to reduce the speed or stop the vehicle according to the vehicle's control requirements. New energy vehicles generally use hydraulic or pneumatic braking systems. The main components of the system include power supply, motor controller, motor, pump, energy storage tank, brake valve, pipeline, and brake. Vehicles commonly use hydraulic (or pneumatic) driven brakes.

[0003] The energy transmission path of existing braking systems is as follows: power battery, motor controller, motor, energy storage device, control valve, and brake. During system operation, electrical energy must be converted into mechanical energy, with liquid or gas serving as an intermediate medium for energy storage or release. The flow of this medium is controlled by the valve body, and the braking mechanism generates braking force through a liquid (or gas) sealed cylinder, ultimately achieving the braking function. Existing braking systems suffer from a large number of components and a long energy transmission path.

[0004] There is currently no effective solution to the above problems. Utility Model Content

[0005] The main objective of this invention is to provide an electromagnetic braking system and a vehicle having it, in order to solve the problems of the large number of components and long energy transmission paths in existing braking systems.

[0006] To achieve the above objectives, according to one aspect of the present invention, an electromagnetic braking system is provided, comprising: a mounting part connected to a mounting base; and a braking part movably connected to the mounting part, the braking part being located on one side of a brake disc, the braking part having an energized state and an de-energized state; wherein, in the energized state, at least a portion of the braking part moves toward one side of the brake disc until it contacts the brake disc, and in the de-energized state, at least a portion of the braking part moves away from the brake disc until the brake disc disengages from the braking part.

[0007] Furthermore, when the braking unit is energized, it moves toward the brake disc in a first direction until it contacts the brake disc. When the power is off, it moves away from the brake disc in a second direction opposite to the first direction until the brake disc disengages from the braking unit.

[0008] Furthermore, the braking unit includes: a magnetic field generating unit movably connected to the mounting unit, the magnetic field generating unit having an energized state and an de-energized state; a friction unit connected to the magnetic field generating unit, the magnetic field generating unit being able to drive the friction unit to move, wherein the friction unit has an initial position away from the brake disc and a working position abutting against the brake disc; and a reset unit disposed on the side of the friction unit away from the brake disc, wherein when the magnetic field generating unit is energized, the friction unit is in the working position, and when the magnetic field generating unit is de-energized, the reset unit resets the friction unit to the initial position.

[0009] Furthermore, the magnetic field generating unit includes: a magnetically conductive part, which is movably connected to the mounting part, and a friction part connected to the magnetically conductive part; a coil, which is wound on the magnetically conductive part; wherein, when the coil is energized, a closed magnetic circuit is formed between the magnetically conductive part and the brake disc, so that the magnetically conductive part drives the friction part to move toward one side of the brake disc until the friction part contacts the brake disc; when the coil is de-energized, the magnetic circuit formed between the magnetically conductive part and the brake disc disappears, and the reset part drives the magnetically conductive part to reset the friction part to the initial position.

[0010] Furthermore, the magnetic guiding part includes: a magnetic guiding body, the axis of the magnetic guiding body in the length direction being arranged parallel to the extension direction of at least one diameter of the brake disc, and a coil extending around the circumferential direction of the magnetic guiding body; and a mounting section, one end of which is connected to the magnetic guiding body, and the other end of which passes through the mounting part and is connected to the friction part. The mounting section is movably arranged relative to the mounting part along the axis of the brake disc rotation shaft to drive the friction part to be in the initial position and the working position.

[0011] Furthermore, there are multiple mounting sections, each connected to the magnetically conductive body, and each mounting section is provided with a friction part. Alternatively, there are multiple mounting sections, and the ends of multiple mounting sections near the brake disc are all connected to a friction part.

[0012] Furthermore, the reset part includes an elastic element, which is arranged circumferentially along the mounting section. The elastic element is located between the magnetic conductive body and the mounting part. When the friction part is in the initial position, the elastic element is in a natural state. When the friction part is in the working position, the elastic element is in a compressed state. The elastic element includes at least one of a spring and an elastic rubber ring.

[0013] Furthermore, the friction part is a friction bushing, one end of which is connected to the mounting section, and the other end of which is the working end. The mounting section can drive the working end to move to the initial position and the working position. Preferably, the friction part is made of a magnetic material.

[0014] Furthermore, the brake disc has a first side and a second side disposed opposite to each other, as well as an outer peripheral surface, and the braking part is located on one side of the first side and the second side, or the braking part is disposed on one side of the outer peripheral surface.

[0015] According to another aspect of the present invention, a vehicle is provided, including an electromagnetic braking system, wherein the electromagnetic braking system is the aforementioned electromagnetic braking system, and the mounting base includes the vehicle's axle structure. Preferably, the vehicle is a mining new energy autonomous driving vehicle.

[0016] By applying the technical solution of this utility model, the braking part is mounted on one side of the brake disc via the mounting part. When braking is required, the braking part is energized, causing at least a portion of the braking part to move from one side of the brake disc until the braking part contacts one side of the brake disc, thus achieving braking. This electromagnetic braking system effectively shortens the energy transfer path during the braking process, and its simple structure effectively saves on component costs.

[0017] Furthermore, the braking unit operates by switching on and off power, utilizing electromagnetism. The generated magnetic force draws the braking unit closer to the brake disc from one side. When energized, the braking unit attracts the brake disc until they come into contact, generating friction and achieving braking. This technical solution solves the problems of complex structure and excessively long energy transmission paths caused by multi-component hydraulic or pneumatic braking systems using motors, energy accumulators, and control valves in traditional braking systems. It also eliminates the delays caused by liquid or gas media and energy conversion time delays in existing hydraulic or pneumatic systems, effectively improving the response speed of the electromagnetic braking system and enhancing the overall safety and reliability of the braking system.

[0033] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0034] To illustrate the technical effects of the electromagnetic braking system in this application, the structure of braking systems in the prior art will be described below, such as... Figure 1 , Figure 2 As shown, Figure 1 , Figure 2 The structure of the braking system in the prior art is such that the energy transmission path is sequentially from the power source to the motor controller, motor, energy storage tank, control valve and finally to the brake. When the braking system is working, it needs to convert electrical energy into mechanical energy. Friction parts 22' are provided on both sides of the brake disc 30'. Liquid or gas is used as an intermediate medium for energy storage or release. The hydraulic or pneumatic driving braking mechanism is controlled by the control valve. The braking mechanism generates braking force through the liquid or gas sealed cylinder, and finally realizes the braking function.

[0035] Combination Figures 3 to 6 As shown, according to a specific embodiment of this application, an electromagnetic braking system is provided.

[0036] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the electromagnetic braking system includes a mounting part 10 and a braking part 20, with the mounting part 10 connected to a mounting base. The braking part 20 is movably connected to the mounting part 10 and is located on one side of the brake disc 30. The braking part 20 has an energized state and an de-energized state. When the braking part 20 is energized, at least a portion of the braking part 20 moves toward the brake disc 30 until it contacts the brake disc 30. When the braking part 20 is de-energized, at least a portion of the braking part 20 moves away from the brake disc 30 until the brake disc 30 disengages from the braking part 20.

[0037] Using the technical solution of this embodiment, the braking part 20 is disposed on one side of the brake disc 30 via the mounting part 10. When braking is required, the braking part 20 is controlled to be in an energized state, causing at least a portion of the braking part 20 to move towards one side of the brake disc 30 until the braking part 20 contacts one side of the brake disc 30, thus achieving braking. This electromagnetic braking system effectively shortens the energy transfer path during the braking process, and its simple structure effectively saves on component costs.

[0038] Furthermore, this embodiment effectively solves the problems of complex structure and excessively long energy transmission paths caused by multi-component hydraulic or pneumatic braking systems using motors, energy storage devices, and control valves in traditional braking systems. It also eliminates the delays caused by liquid or gas media and energy conversion time delays in existing hydraulic or pneumatic systems, effectively improving the response speed of the electromagnetic braking system and enhancing the safety and reliability of the entire braking system.

[0039] It should be noted that in this application, the braking part 20 can be configured to be movable relative to the brake disc 30 as a whole, or it can be configured to be movable relative to the brake disc 30 in part. That is, it is only necessary to configure the braking part 20 to be able to move relative to the brake disc 30 to achieve contact braking.

[0040] Furthermore, in this embodiment, the mounting part 10 is connected to the mounting base, which can be an axle. The mounting part 10 is fixedly connected to the axle, so that the mounting part 10 cannot rotate relative to the brake disc 30. The mounting part 10 provides stable support for the braking system. Figure 5 As shown, the mounting part 10 is a mounting block structure, wherein the mounting part 10 has a V-shaped structure, and a connection hole for connecting to the axle is provided at the corner of the mounting part 10. In other embodiments, the mounting part 10 can be other structures, as long as it can be fixedly connected to the axle.

[0041] Specifically, in the energized state, the braking part 20 moves towards the brake disc 30 along the first direction until it contacts the brake disc 30. In the de-energized state, the braking part 20 moves away from the brake disc 30 along the second direction opposite to the first direction until the brake disc 30 disengages from the braking part 20. Thus, by energizing the braking part 20, its movement along the first direction can be controlled. When the braking part 20 moves to contact the brake disc 30, pressure is generated between the braking part 20 and the brake disc 30, and this pressure gradually increases. This creates friction between the braking part 20 and the brake disc 30, causing the brake disc 30 to brake. This friction counteracts the rotational force of the brake disc 30 until the brake disc 30 stops rotating, achieving braking. When it is necessary to release the brake, simply switch the braking part 20 to the de-energized state. The braking part 20 then loses the magnetic attraction to the brake disc 30, and can move along the second direction until it disengages from the brake disc 30.

[0042] It should be noted that the first direction and the second direction refer to the axial movement of the braking unit 20 along the rotation axis of the brake disc 30. Specifically, the first direction is the direction in which the braking unit 20 moves closer to the brake disc 30 along the rotation axis, and the second direction is the direction in which the braking unit 20 moves away from the brake disc 30 along the rotation axis. This arrangement effectively shortens the transmission path of the braking force, enabling the braking and releasing actions of the brake disc to be performed in a short time, thus effectively improving the braking efficiency of the electromagnetic braking system.

[0043] Furthermore, such as Figures 3 to 5As shown, the braking unit 20 includes a magnetic field generating unit 21, a friction unit 22, and a reset unit 23. The magnetic field generating unit 21 is movably connected to the mounting unit 10 and has an energized state and an de-energized state. The friction unit 22 is connected to the magnetic field generating unit 21, and the magnetic field generating unit 21 can drive the friction unit 22 to be movably positioned. The friction unit 22 has an initial position away from the brake disc 30 and a working position abutting against the brake disc 30. The reset unit 23 is located on the side of the friction unit 22 away from the brake disc 30. When the magnetic field generating unit 21 is energized, the friction unit 22 is in the working position; when the magnetic field generating unit 21 is de-energized, the reset unit 23 resets the friction unit 22 to its initial position. The mounting part 10 is connected to the mounting base, and the magnetic field generating part 21 is movably connected to the mounting part 10. When the magnetic field generating part 21 is energized, it generates a magnetic force, which causes it to move along a first direction and approach the mounting part 10 and the brake disc 30. Simultaneously, it moves the friction part 22 to its working position for braking. When the magnetic field generating part 21 is de-energized, it no longer generates a magnetic force. Based on the restoring force of the reset part 23, it moves along a second direction and away from the mounting part 10 and the brake disc 30. Simultaneously, it resets the friction part 22 to its initial position. By utilizing electromagnetic force and the elastic force of the reset part 23, automatic contact and reset of the brake part 20 are achieved, improving the automation level of the braking system, ensuring timely braking in emergency braking situations, and enhancing the safety of the electromagnetic braking system.

[0044] In one embodiment of this application, such as Figure 3 As shown, the magnetic field generating part 21 is located on one side of the mounting part 10 and is disposed through the mounting part 10. The magnetic field generating part 21 can move towards the mounting part 10 in a first direction and away from the mounting part 10 in a second direction via its through-part. The other side of the magnetic field generating part 21 is connected to the friction part 22, meaning the friction part 22 is located on the other side of the mounting part 10. The friction part 22 is connected to the portion of the magnetic field generating part 21 that passes through the mounting part 10. When the magnetic field generating part 21 moves in the first and second directions, it can simultaneously move the friction part 22 towards or away from the brake disc 30. When the magnetic field generating part 21 moves in the first direction, it moves the friction part 22 in the first direction until the friction part 22 contacts the brake disc 30, generating braking force. When the magnetic field generating part 21 is de-energized, it moves in the second direction based on the elastic restoring force of the reset part 23, causing the friction part 22 to separate from the brake disc 30.

[0045] Specifically, such as Figure 3 , Figure 5As shown, the magnetic field generating unit 21 includes a magnetically conductive part 211 and a coil 212. The magnetically conductive part 211 is movably connected to the mounting part 10, and the friction part 22 is connected to the magnetically conductive part 211. The coil 212 is wound around the magnetically conductive part 211. When the coil 212 is energized, a closed magnetic circuit is formed between the magnetically conductive part 211 and the brake disc 30, causing the magnetically conductive part 211 to move the friction part 22 toward one side of the brake disc 30 until the friction part 22 contacts the brake disc 30. When the coil 212 is de-energized, the magnetic circuit formed between the magnetically conductive part 211 and the brake disc 30 disappears, and the reset part 23 drives the magnetically conductive part 211 to reset the friction part 22 to its initial position. A magnetic field is generated by winding a coil 212 around the magnetic conductor 211 and energizing the coil 212. The magnitude of the magnetic field can be directly controlled by the strength of the current flowing through the coil, thereby controlling the magnitude of the braking force generated by the magnetic field generating unit 21 driving the friction unit 22 to contact the brake disc 30. In other words, the friction between the friction unit 22 and the brake disc 30 can be controlled by the magnitude of the current in the coil 212 to achieve braking. When the coil 212 is de-energized, the magnetic circuit between the magnetic conductor 211 and the brake disc 30 disappears. The magnetic field generating unit 21, based on the elastic restoring force of the reset unit 23, moves the friction unit 22 away from the brake disc 30, releasing the brake. This method of controlling the movement of the friction unit 22 by switching the coil 212 on and off provides a short response time and stable braking effect, enabling rapid, accurate, and stable braking in an electromagnetic braking system.

[0046] It should be noted that the principle by which the braking part 20 makes contact with the brake disc 30 and generates braking force is based on the electromagnetic force generated by the energized coil 212. When current flows through the coil 212, a magnetic field is formed. The magnetic field closes along the path of least magnetic resistance, and the magnetic circuit is preferentially generated from the magnetically conductive part 211. A closed magnetic flux path is formed through the friction part 22 and the brake disc 30. When the magnetic field is formed, the magnetic lines of force attempt to shorten their path to reduce magnetic resistance and increase magnetic permeability, so that an attractive force is generated between the friction part 22 and the brake disc 30. The magnitude of this attractive force is proportional to the current intensity in the coil 212. By adjusting the current intensity in the coil 212, the intensity of the electromagnetic force can be precisely adjusted, thereby adjusting the pressure applied by the braking part 20 to the brake disc 30. The friction between the two can prevent the brake disc 30 from rotating and achieve the braking effect. The braking can also be released by cutting off the current.

[0047] Furthermore, such as Figure 3 , Figure 4As shown, the magnetically conductive part 211 includes a magnetically conductive body 2110 and a mounting section 2111. The axis of the magnetically conductive body 2110 in the length direction is arranged parallel to the extension direction of at least one diameter of the brake disc 30. The coil 212 extends circumferentially around the magnetically conductive body 2110. One end of the mounting section 2111 is connected to the magnetically conductive body 2110, and the other end of the mounting section 2111 passes through the mounting part 10 and is connected to the friction part 22. The mounting section 2111 is movably arranged relative to the mounting part 10 along the axis of rotation of the brake disc 30 to drive the friction part 22 to be in the initial position and the working position. The magnetically conductive part 211 is divided into two parts: the magnetically conductive body 2110 and the mounting section 2111. The magnetically conductive body 2110 is circumferentially spirally wound with a coil 212. The magnetically conductive body 2110 is mainly used to generate magnetic lines of force. The mounting section 2111 is mainly used to pass through the mounting part 10 and also serves as a magnetic conductor, realizing the connection between the magnetically conductive body 2110 and the friction part 22, and extending the magnetic lines of force to the mounting section 2111, the friction part 22, and the brake disc 30, so that the magnetic lines of force form a closed magnetic circuit. At the same time, the configuration of the magnetically conductive body 2110 and the mounting section 2111 can flexibly adapt to brake discs 30 of different sizes, improving the practicality of the electromagnetic braking system.

[0048] Multiple mounting sections 2111 are provided, each connected to the magnetically conductive body 2110. Each mounting section 2111 is equipped with a friction part 22. By providing multiple mounting sections 2111 and multiple friction parts 22, a more uniform braking effect can be achieved, reducing vibration and noise during braking and improving braking comfort and stability. Specifically, for example... Figure 3 , Figure 5 As shown in the figure, there are two mounting sections 2111, which are respectively located at both ends of the magnetic conductive body 2110.

[0049] In another embodiment of this application, there are multiple mounting segments 2111, and the ends of the multiple mounting segments 2111 near the brake disc 30 are all connected to a friction part 22. This arrangement can uniformly achieve the braking effect on the brake disc 30, improving braking reliability. In this embodiment, the friction part 22 can be made of a non-magnetic material, wherein the magnetic lines of force generated by the magnetic part 211 can penetrate the friction part 22 and form a closed loop with the brake disc 30.

[0050] In another embodiment of this application, the friction part 22 may also be configured as a partially magnetic structure. For example, a magnetic sleeve may be provided at the connection with the mounting section 2111. This allows the magnetic lines of force generated by the magnetic part 211 to form a closed magnetic circuit with the brake disc 30 with only a small amount of energy.

[0051] Furthermore, such as Figure 3 , Figure 4As shown, the reset part 23 includes an elastic element, which is arranged circumferentially along the mounting section 2111. The elastic element is located between the magnetic conductive body 2110 and the mounting part 10. When the friction part 22 is in the initial position, the elastic element is in a natural state. When the friction part 22 is in the working position, the elastic element is in a compressed state. The elastic element includes at least one of a spring and an elastic rubber ring. By providing an elastic element between the magnetic conductive body 2110 and the mounting part 10, and uniformly arranging the elastic element circumferentially along the mounting section 2111, not only can the rapid reset of the friction part 22 after power failure be ensured, but the impact during braking can also be absorbed, protecting the braking system and extending the service life of the system. In this embodiment, the elastic element can prevent the impact caused by the collision between the magnetic conductive body 2110 and the mounting part due to excessive braking force generated by excessive current, and can also alleviate the vibration generated by the friction part 22 and the brake disc 30 during braking, thus playing a bidirectional buffering role and providing dual protection for the braking system.

[0052] In another embodiment of this application, the friction part 22 is a friction bushing. One end of the friction bushing is connected to the mounting section 2111, and the other end of the friction bushing is a working end. The mounting section 2111 can drive the working end to move to the initial position and the working position. In this embodiment, the friction part 22 is made of a magnetically conductive material. By using the friction bushing, stronger frictional force can be generated when the brake disc 30 contacts the bushing, reducing energy consumption during braking, improving braking response speed and efficiency. At the same time, the bushing also has advantages such as wear resistance, low cost, good braking smoothness, and easy replacement and maintenance, which can improve the performance and service life of the braking system.

[0053] It should be noted that the friction part 22, the brake disc 30, and the magnetic conductive part 211 are all made of magnetically conductive material to ensure that a closed magnetic path is formed between the magnetic field generating part 21, the friction part 22, and the brake disc 30 to generate sufficient electromagnetic attraction between the brake disc 30 and the bushing. At the same time, the mounting part 10 is made of non-magnetically conductive material to avoid the magnetic field from being connected to the mounting base through the mounting part 10, which would cause unnecessary magnetic field dispersion or interference in the braking system and reduce the performance of the braking system.

[0054] Furthermore, the brake disc 30 has a first side surface 31 and a second side surface 32 disposed opposite to each other, and an outer peripheral surface 33. The braking part 20 is located on one side of the first side surface 31 and the second side surface 32. The braking part 20 includes a magnetic field generating part 21, a friction part 22, and a reset part 23. Figure 3 , Figure 5As shown, in this embodiment, the side of the brake disc 30 closest to the friction part 22 is the first side surface 31, and the side of the brake disc 30 furthest from the friction part 22 is the second side surface 32. When the brake part 20 is energized, it moves towards the first side surface 31 along a first direction, thereby causing the friction part 22 to move towards the first side surface 31 until the friction part 22 contacts the first side surface to achieve the braking function. When the brake part 20 is de-energized, under the restoring force of the reset part 23, it moves away from the first side surface 31 along a second direction, thereby causing the friction part 22 to move away from the first side surface 31 to achieve brake release.

[0055] In another embodiment of this application, the braking part 20 is located on one side of the outer peripheral surface 33. The braking part 20 includes a magnetic field generating part 21, a friction part 22, and a reset part 23. When the braking part 20 is energized, it drives the friction part 22 to move along a first direction until it contacts the outer peripheral surface 33. The friction part 22 provides braking force by rubbing against the outer peripheral surface. At this time, due to the maximum friction torque, the braking system can achieve effective braking even under relatively light pressure, reducing energy consumption during braking and further improving braking response speed and efficiency. In this embodiment, the direction of movement perpendicular to the rotation axis of the brake disc 30 and closer to the brake disc 30 is the first direction, and the direction of movement perpendicular to the rotation axis of the brake disc 30 and farther from the brake disc 30 is the second direction. In this embodiment, the specific structure of the magnetic conductive part 211 can be adapted to the arc-shaped peripheral surface of the brake disc 30, so that the friction surface of the friction part 22 achieves good contact with the outer peripheral surface of the brake disc 30. For example, the magnetic conductive part 211 can be configured as an arc-shaped structure that bends along the circumference of the brake disc 30, and the friction surface of the friction part 22 can be configured as an arc-shaped contact surface that extends along the circumference of the brake disc 30.

[0056] According to another specific embodiment of this application, a vehicle is also provided, including an electromagnetic braking system, which is the electromagnetic braking system described in the above embodiments, wherein the mounting base includes the vehicle's axle structure. In this embodiment, the vehicle can be a mining new energy autonomous driving vehicle.

[0057] By applying the technical solution of this embodiment, the electromagnetic braking system is applied to mining new energy autonomous driving vehicles. Through the effective integration of the vehicle axle structure, it can not only provide high-speed and stable braking effects in the complex environment of mining operations, enhancing the safety performance of mining new energy autonomous driving vehicles, but also greatly reduce the need for manual intervention, improve the autonomous operation capability of the vehicle, reduce safety hazards caused by braking system failures in mining operations, and improve overall operation efficiency. At the same time, the electromagnetic braking system in this embodiment has a simpler structure and lower maintenance costs, which can reduce the maintenance investment of the braking system, reduce operating costs, and improve economic benefits.

[0058] Combination Figure 6 As shown in the electromagnetic braking system structure diagram, the above-described embodiments of this utility model achieve the following technical effects:

[0059] Compared to traditional braking systems, electromagnetic braking systems reduce the number of components, simplifying the system structure, shortening the braking energy transmission path, reducing energy loss, and improving system efficiency. Compared to traditional braking systems where braking units 20 are installed on both sides of the brake disc 30, electromagnetic brakes can be freely installed on both sides of the brake disc 30, and multiple electromagnetic brakes can be used in parallel with multiple branches, making the structural design more flexible.

[0060] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] In addition to the above, it should be noted that the terms "one embodiment," "another embodiment," and "embodiment" used in this specification refer to specific features, structures, or characteristics described in connection with that embodiment, which are included in at least one embodiment described in the general description of this application. The appearance of the same expression in multiple places in the specification does not necessarily refer to the same embodiment. Furthermore, when a specific feature, structure, or characteristic is described in connection with any embodiment, the intention is to suggest that implementing such a feature, structure, or characteristic in conjunction with other embodiments also falls within the scope of this utility model.

[0062] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
