Description

Technical Field

[0001] This application relates to the field of relay technology, and in particular to a relay and its contact portion. Background Technology

[0002] In photovoltaic inverters, to ensure the entire unit meets safety regulations, a configuration of two relays connected in series is required. The two relays are installed independently, meaning each relay has its own independent electromagnetic coil and independent contacts. During operation, contact lead 1 of one relay needs to be soldered to the PCB board, and contact lead 2 of the other relay also needs to be soldered to the PCB board. Contact lead 1 of one relay and contact lead 2 of the other relay are connected via the PCB.

[0003] The two relays connected in series mentioned above each include a moving spring, with moving contacts at both ends. A flexible connector is used to electrically connect the moving contacts. To accommodate high-current environments, the cross-sectional area of ​​the flexible connector is typically increased. However, as the cross-sectional area of ​​the flexible connector increases, the contact pressure between the moving and stationary contacts is affected. Summary of the Invention

[0004] Therefore, it is necessary to provide a relay and its contact parts to improve current carrying capacity while ensuring the contact pressure between the moving contact and the stationary contact.

[0005] In a first aspect, this application provides a contact portion of a relay, comprising:

[0006] support;

In the direction from the fifth end to the sixth end, the first elastic arm is inclined toward the first conductive element and slidably connected to the first conductive element. The second elastic arm has a seventh end and an eighth end opposite to each other. The seventh end is connected to the connecting portion. In the direction from the seventh end to the eighth end, the second elastic arm is inclined toward the second conductive element and slidably connected to the second conductive element.

[0014] In one embodiment, the elastic reset member is disposed on the side of the first conductive member and the second conductive member away from the bracket, and the soft conductive member is disposed on the side of the first conductive member and the second conductive member facing the bracket.

[0015] In one embodiment, one end of the elastic reset member is fixedly connected to the first conductive member, the other end of the elastic reset member is fixedly connected to the second conductive member, and the middle part of the elastic reset member arches in a direction away from the first conductive member and the second conductive member.

[0016] In one embodiment, the contact portion of the relay further includes a first stationary spring, the first stationary spring having a first stationary contact, the first stationary contact being disposed opposite to the first moving contact; the first conductive member having a first end, the first moving contact being disposed at the first end; the contact portion of the relay further includes a first compression spring for cooperating with a pushing portion, the first compression spring being connected to the first end, and under the pushing of the pushing portion, the first end being able to rotate toward the first stationary spring so that the first moving contact contacts the first stationary contact.

[0017] In one embodiment, at least two first conductive elements are provided; the first compression spring includes at least two first compression spring arms, and the at least two first compression spring arms are connected to the at least two first conductive elements in a one-to-one correspondence.

[0018] In one embodiment, the contact portion of the relay further includes a second stationary spring, the second stationary spring having a second stationary contact, the second stationary contact being disposed opposite to the second moving contact; the second conductive member has a third end, the second moving contact being disposed at the third end; the contact portion of the relay further includes a second compression spring for cooperating with a pushing portion, the second compression spring being connected to the third end, and under the pushing of the pushing portion, the third end can rotate toward the second stationary spring so that the first moving contact contacts the first stationary contact.

[0019] In one embodiment, at least two second conductive elements are provided; the second compression spring element includes at least two second compression spring arms, and the at least two compression spring arms are connected to the at least two second conductive elements in a one-to-one correspondence.

[0020] In one embodiment, the flexible conductive element is arched, and the flexible conductive element arches in a direction away from the first conductive element and the second conductive element.

[0021] In one embodiment, the first conductive element and the second conductive element are spaced apart along a first direction; at least two of each of the first and second conductive elements are provided, the at least two first conductive elements are spaced apart along a second direction, the at least two second conductive elements are spaced apart along the second direction, and adjacent first conductive elements and second conductive elements in the first direction are electrically connected by at least one of the flexible conductive elements; wherein the first direction intersects the second direction.

[0023] Secondly, this application also provides a relay, comprising:

[0024] The contact portion of any of the above; and

[0025] The pushing part includes a first pushing member and a second pushing member. The first pushing member is disposed corresponding to the first conductive member and is used to push the first conductive member to rotate relative to the bracket. The second pushing member is disposed corresponding to the second conductive member and is used to push the second conductive member to rotate relative to the bracket.

[0026] The aforementioned relay and its contact parts, by incorporating a first conductive element and a second conductive element, possess excellent conductivity, enabling them to carry current and thus improving the relay's current-carrying capacity, allowing it to be used in high-current environments. Since the first and second conductive elements are separately arranged and electrically connected via a flexible conductive element, this flexible element acts as a bridge. By changing the cross-sectional area of ​​the flexible conductive element, the current-carrying capacity can be effectively increased. Simultaneously, the flexible conductive element also acts as a buffer and transition element, enhancing the overall structural stability and reliability. Because both the first and second conductive elements are movably connected to the bracket, they can move freely within a certain range. This allows the first moving contact to quickly contact or separate from the first stationary contact, and the second moving contact to quickly contact or separate from the second stationary contact. Simultaneously, it ensures stable contact between the first and second moving contacts, as well as between the first and second moving contacts, achieving low contact resistance.

[0036] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0037] See Figure 1 and Figure 4 One embodiment of this application provides a relay including a base 10, a contact portion 20, a pushing portion 30, and a magnetic circuit portion. The contact portion 20, the pushing portion 30, and the magnetic circuit portion are all disposed on the base 10.

[0038] See Figure 2 and Figure 5 The contact portion 20 includes a bracket 21, a movable spring assembly 22, and a flexible conductive element 23. The bracket 21 is fixed to the base 10. The movable spring assembly 22 includes a first conductive element 221 and a second conductive element 222, which are separately disposed and movably connected to the bracket 21. The first conductive element 221 has a first movable contact 2211, and the second conductive element 222 has a second movable contact 2221.

[0039] It should be noted that both the first conductive element 221 and the second conductive element 222 are rigid structures, and they are virtually impossible to deform. (See reference...) Figure 1 and Figure 4The contact portion 20 also includes a stationary spring assembly 24. The stationary spring assembly 24 includes a first stationary spring 241 and a second stationary spring 242, both of which are disposed on the base 10. The first stationary spring 241 has a first stationary contact 2411, which is opposite to a first moving contact 2211. The second stationary spring 242 has a second stationary contact 2421, which is opposite to a second moving contact 2221. When the relay is energized, the magnetic circuit generates a magnetic field, causing the pushing portion 30 to move under the influence of the magnetic field. This causes the first conductive element 221 and the second conductive element 222 to move relative to the bracket 21, resulting in contact between the first moving contact 2211 and the first stationary contact 2411, and between the second moving contact 2221 and the second stationary contact 2421.

[0040] By setting the first conductive element 221 and the second conductive element 222, the first conductive element 221 and the second conductive element 222 have good conductivity, so that the first conductive element 221 and the second conductive element 222 have current carrying capacity.

[0041] Since both the first conductive element 221 and the second conductive element 222 are rigid structures, a flexible conductive element 23 is used to electrically connect them in order to further improve the current carrying capacity. In this way, the flexible conductive element 23 can act as a bridge, further enhancing the current carrying capacity of the relay without changing its size. Furthermore, the flexible conductive element 23 can also act as a buffer and transition element, enhancing the overall stability and reliability of the structure.

[0042] However, since the first conductive element 221 and the second conductive element 222 are rigid structures, they are both movably connected to the bracket 21. This allows the first conductive element 221 and the second conductive element 222 to move freely within a certain range, enabling the first moving contact 2211 to quickly contact or separate from the first stationary contact 2411, and the second moving contact 2221 to quickly contact or separate from the second stationary contact 2421. At the same time, it ensures that the first moving contact 2211 and the first stationary contact 2411, as well as the second moving contact 2221 and the second stationary contact 2421, maintain stable contact, thus achieving low contact resistance.

[0043] In one embodiment, see Figure 7 The first conductive element 221 and the second conductive element 222 are arranged side by side. Specifically, the first conductive element 221 and the second conductive element 222 are arranged side by side and spaced apart in a first direction. The first direction is represented by X.

[0044] Further, see Figure 2The first conductive element 221 has a first end and a second end opposite to each other. A first moving contact 2211 is provided at the first end, and the second end is rotatably connected to the bracket 21 via a first rotating shaft 25.

[0045] Further, see Figure 2 The second conductive element 222 has a third end and a fourth end opposite to each other. The second end and the fourth end are positioned close to each other, and the bracket 21 is positioned corresponding to the second end and the fourth end. The second moving contact 2221 is located at the third end, and the fourth end is rotatably connected to the bracket 21 via the second rotating shaft 26. This arrangement makes the structure of the contact portion 20 compact, enabling complex contact actions within a limited space. Furthermore, by placing the first moving contact 2211 at the end of the first conductive element 221 away from the second conductive element 222, and the second moving contact 2221 at the end of the second conductive element 222 away from the first conductive element 221, arc interference generated during the operation of the moving and stationary contacts can be reduced.

[0046] Specifically, see Figure 3 The bracket 21 is U-shaped. The two ends of the first rotating shaft 25 are connected to the opposite sides of the bracket 21, and the two ends of the second rotating shaft 26 are connected to the opposite sides of the bracket 21.

[0047] In one embodiment, see Figure 2 One end of the flexible conductive element 23 is electrically connected to the first conductive element 221, and the other end of the flexible conductive element 23 is electrically connected to the second conductive element 222. This arrangement reduces the impact of the flexible connection reaction force on the contact portion 20.

[0048] Optionally, see Figure 2 One end of the flexible conductive element 23 is electrically connected to the second end of the first conductive element 221, and the other end of the flexible conductive element 23 is electrically connected to the fourth end of the second conductive element 222. Optionally, the electrical connection method between the flexible conductive element 23 and the first conductive element 221 and the second conductive element 222 includes, but is not limited to, welding. Electrically connecting the flexible conductive element 23 near the first rotating shaft 25 and the second rotating shaft 26 minimizes the deformation of the flexible conductive element 23, thereby reducing the impact of the reaction force generated by the flexible conductive element 23 on the rotation of the first conductive element 221 and the second conductive element 222.

[0049] In one embodiment, see Figure 2The flexible conductive element 23 is arched, curving away from the first conductive element 221 and the second conductive element 222. This arched shape provides excellent elastic deformation capability. When the first conductive element 221 and the second conductive element 222 rotate, the flexible conductive element 23 can buffer external forces through elastic deformation, reducing the impact on the first conductive element 221 and the second conductive element 222, thus improving the structural stability of the moving spring assembly 22. Under stress, the arched flexible conductive element 23 can evenly distribute pressure across the entire contact portion 20, ensuring stable contact pressure between the moving and stationary contacts, thereby reducing contact resistance and improving conductivity.

[0050] In one embodiment, the flexible conductive element 23 is at least one of a flexible connecting wire, a flexible braided wire, and a multilayer copper foil flexible connecting strip.

[0051] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5 The contact portion 20 also includes a first compression spring 27. The first compression spring 27 is connected to the first end of the first conductive member 221. Specifically, the first compression spring 27 is located on the side of the first conductive member 221 away from the stationary spring assembly 24 and is riveted to the first end of the first conductive member 221. The first compression spring 27 is used to cooperate with the first pusher 31 of the push portion 30. Under the push of the first pusher 31, the first end can rotate toward the first stationary spring 241 so that the first moving contact 2211 contacts the first stationary contact 2411. When the coil of the magnetic circuit portion is energized, the magnetic circuit portion generates a magnetic field. The first pusher 31 moves under the action of the magnetic field, thereby pushing the first compression spring 27, so that the first end of the first conductive member 221 rotates toward the first stationary spring 241 until the first moving contact 2211 contacts the first stationary contact 2411. By providing a first compression spring 27, the first compression spring 27 is used to provide the pressure required for the first moving contact 2211 to contact the first stationary contact 2411.

[0052] Optionally, the first compression spring 27 is Z-shaped. By changing the structure of the first compression spring 27, the pressure between the first moving contact 2211 and the first stationary contact 2411 can be increased, thereby reducing the contact resistance of the contact portion 20.

[0053] In one embodiment, see Figure 1 , Figure 2 , Figure 4 and Figure 5The contact portion 20 also includes a second compression spring 28, which is connected to the third end of the second conductive member 222. Specifically, the second compression spring 28 is located on the side of the second conductive member 222 away from the stationary spring assembly 24 and is riveted to the third end of the second conductive member 222. The second compression spring 28 is used to cooperate with the second pusher 32 of the push portion 30. Under the push of the second pusher 32, the third end can rotate toward the direction of the second stationary spring 242 so that the second moving contact 2221 contacts the second stationary contact 2421. When the coil of the magnetic circuit portion is energized, the magnetic circuit portion generates a magnetic field. The second pusher 32 moves under the action of the magnetic field, thereby pushing the second compression spring 28, so that the third end of the second conductive member 222 rotates toward the direction of the second stationary spring 242 until the second moving contact 2221 contacts the second stationary contact 2421. By providing a second compression spring 28, the second compression spring 28 is used to provide the pressure required for the second moving contact 2221 to contact the second stationary contact 2421.

[0054] Optionally, the second compression spring 28 is Z-shaped. By changing the structure of the second compression spring 28, the pressure between the second moving contact 2221 and the second stationary contact 2421 can be increased, thereby reducing the contact resistance of the contact portion 20.

[0055] In one embodiment, the first stationary reed 241 has at least two first stationary contacts 2411, which are spaced apart along a second direction. The second stationary reed 242 has at least two second stationary contacts 2421, which are spaced apart along a second direction.

[0056] See Figure 7 The relay comprises at least two first conductive elements 221, which are spaced apart along a second direction, and each of the at least two first conductive elements 221 has a first moving contact 2211. It also comprises at least two second conductive elements 222, which are spaced apart along a second direction, and each of the at least two second conductive elements 222 has a second moving contact 2221. Adjacent first conductive elements 221 and second conductive elements 222 in the first direction are electrically connected via a flexible conductive element 23. When the relay is in operation, at least two first moving contacts 2211 can make contact with at least two first stationary contacts 2411, and at least two second moving contacts 2221 can make contact with at least two second stationary contacts 2421, forming a parallel circuit. This reduces the circuit contact resistance, effectively reducing the temperature rise of the contacts and thus reducing relay contact loss.

[0057] In one embodiment, see Figure 7The first spring member 27 includes at least two first spring arms 271, all of which are spaced apart along the second direction. Each first spring arm 271 is connected to a corresponding first conductive element 221. The first pusher 31 is positioned opposite the end of each first spring arm 271 that is away from the first moving contact 2211. It is understood that the first spring member 27 is forked to form at least two first spring arms 271. Thus, a single pusher 31 can simultaneously and flexibly push the first conductive elements 221 arranged side-by-side in the second direction through the forked first spring members 27, ensuring the consistency and reliability of contact among multiple sets of parallel contacts, while also reducing the number of pushers 31 and saving costs.

[0058] In one embodiment, see Figure 7 The second spring member 28 includes at least two second spring arms 281, all of which are spaced apart along the second direction, and each second spring arm 281 is connected to a corresponding second conductive member 222. The second pusher 32 is positioned opposite the end of each second spring arm 281 that is away from the second moving contact 2221. It is understood that the second spring member 28 is forked to form at least two second spring arms 281. Thus, a single second pusher 32 can flexibly push the second conductive members 222 arranged side-by-side in the second direction simultaneously through the forked second spring members 28, ensuring the consistency and reliability of contact among multiple sets of parallel contacts, while also reducing the number of second pushers 32 and saving costs.

[0059] In one embodiment, see Figure 1 and Figure 4 The contact portion 20 also includes an elastic reset member 29. The elastic reset member 29 is a restoring spring. The elastic reset member 29 is connected to the first conductive member 221 and the second conductive member 222, and is used to drive the first conductive member 221 and the second conductive member 222 to reset. In this way, under the action of the elastic reset member 29, the first conductive member 221 and the second conductive member 222 can be restored to the released state.

[0060] In one embodiment, see Figure 1 and Figure 2 The elastic reset member 29 is located on the side of the first conductive member 221 and the second conductive member 222 facing the stationary spring assembly 24, while the soft conductive member 23 is located on the side of the first conductive member 221 and the second conductive member 222 away from the stationary spring assembly 24. It is understood that... Figure 1 In this configuration, the elastic reset member 29 is located below the first conductive member 221 and the second conductive member 222, providing support for them; the flexible conductive member 23 is located above the first conductive member 221 and the second conductive member 222. This arrangement prevents interference between the elastic reset member 29 and the flexible conductive member 23.

[0061] Further, see Figure 2 and Figure 3 The elastic reset member 29 includes a connecting portion 293, a first elastic arm 291, and a second elastic arm 292. The connecting portion 293 is connected to the bracket 21. The first elastic arm 291 and the second elastic arm 292 are respectively disposed on opposite sides of the connecting portion 293. The end of the first elastic arm 291 facing away from the connecting portion 293 is slidably connected to the first conductive member 221, and the end of the second elastic arm 292 facing away from the connecting portion 293 is slidably connected to the second conductive member 222. Under the action of the first pushing member 31, the first end rotates towards the first stationary spring 241, and the first elastic arm 291 undergoes elastic deformation under the action of external force. Under the action of the second pushing member 32, the third end rotates towards the second stationary spring 242, and the second elastic arm 292 undergoes elastic deformation under the action of external force. When the external force on the first conductive element 221 and the second conductive element 222 is removed, the first elastic arm 291 returns to its original state due to its own elastic properties, thereby driving the first end to rotate away from the first stationary spring 241, so that the first conductive element 221 is reset. At the same time, the second elastic arm 292 returns to its original state due to its own elastic properties, thereby driving the third end to rotate away from the second stationary spring 242, so that the second conductive element 222 is reset.

[0062] Specifically, see Figure 1 The first elastic arm 291 has a fifth end and a sixth end, the fifth end of which is connected to the connecting part 293. In the direction from the fifth end to the sixth end, the first elastic arm 291 is inclined towards the first conductive element 221 and slidably connected to it. This arrangement facilitates the first elastic arm 291 in resetting the first conductive element 221 during its return to its original state, while also providing a certain supporting force to the first conductive element 221.

[0063] Specifically, see Figure 1 The second elastic arm 292 has a seventh end and an eighth end, the seventh end of which is connected to the connecting part 293. In the direction from the seventh end to the eighth end, the second elastic arm 292 is inclined toward the second conductive member 222 and is slidably connected to the second conductive member 222. This arrangement facilitates the second elastic arm 292 to drive the second conductive member 222 to reset during the process of returning to its original state, while the second elastic arm 292 provides a certain supporting force for the second conductive member 222.

[0064] In another embodiment, see [reference] Figure 4 and Figure 5The elastic reset member 29 is located on the side of the first conductive member 221 and the second conductive member 222 away from the stationary spring assembly 24, and the soft conductive member 23 is located on the side of the first conductive member 221 and the second conductive member 222 facing the stationary spring assembly 24. It is understood that... Figure 4 In this configuration, the elastic reset member 29 is positioned above the first conductive member 221 and the second conductive member 222 to lift them; the soft conductive member 23 is positioned below the first conductive member 221 and the second conductive member 222. This arrangement prevents interference between the elastic reset member 29 and the soft conductive member 23.

[0065] Further, see Figure 5 One end of the elastic reset member 29 is fixedly connected to the first conductive member 221, and the other end is fixedly connected to the second conductive member 222. The middle part of the elastic reset member 29 arches away from the first conductive member 221 and the second conductive member 222. Under the action of the pushing part 30, the first end rotates towards the first stationary spring 241, and the third end rotates towards the second stationary spring 242. The elastic reset member 29 undergoes elastic deformation under the action of external force. When the external force on the first conductive member 221 and the second conductive member 222 is removed, the elastic reset member 29 returns to its original state by its own elastic properties, thereby causing the first end to rotate away from the first stationary spring 241 and the third end to rotate away from the second stationary spring 242, thus resetting the first conductive member 221 and the second conductive member 222.

[0066] In one embodiment, see Figure 1 and Figure 2 The first compression spring 27 is located on the side of the first conductive element 221 opposite to the first stationary spring 241, and the second compression spring 28 is located on the side of the second conductive element 222 opposite to the second stationary spring 242. This avoids motion interference.

[0067] Furthermore, the elastic reset member 29 is disposed on the side of the first conductive member 221 and the second conductive member 222 facing the first stationary spring 241 and the second stationary spring 242, or the elastic reset member 29 is disposed on the side of the first conductive member 221 and the second conductive member 222 away from the first stationary spring 241 and the second stationary spring 242, and the elastic reset member 29 is connected to the first conductive member 221 and the second conductive member 222.

[0068] When the relay is in operation, the first spring member 27 presses against at least two first conductive members 221, causing the at least two first conductive members 221 to rotate relative to the bracket 21, so that at least two first moving contacts 2211 and at least two first stationary contacts 2411 make contact one-to-one. Simultaneously, the second spring member 28 presses against at least two second conductive members 222, causing the at least two second conductive members 222 to rotate relative to the bracket 21, so that at least two second moving contacts 2221 and at least two second stationary contacts 2421 make contact one-to-one. During the rotation of the first conductive members 221 and second conductive members 222, the elastic reset member 29 deforms.

[0069] When the first compression spring 27 removes the pressure applied to the first conductive member 221 and the second compression spring 28 removes the pressure applied to the second conductive member 222, the elastic reset member 29 restores its deformation to push at least two first conductive members 221 and at least two second conductive members 222 to rotate in opposite directions to reset.

[0070] Thus, with the cooperation of the first compression spring 27, the second compression spring 28, and the elastic reset member 29, the first conductive member 221 and the second conductive member 222 can maintain dynamic balance and stability, ensuring that at least two first moving contacts 2211 and at least two first stationary contacts 2411 are in stable contact in a one-to-one correspondence, and at least two second moving contacts 2221 and at least two second stationary contacts 2421 are in stable contact in a one-to-one correspondence, so as to form a parallel circuit and achieve the effect of reducing temperature rise.

[0071] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0072] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0073] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0074] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0075] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
