Description

Technical Field

In one embodiment of the present application, a magnetic pole adsorption type wireless charger includes a face shell, a bottom shell, a mainboard, a wireless charging coil, a magnetic part and a magnetic part adsorption part; the face shell and the bottom shell together enclose an installation cavity, and the mainboard, the wireless charging coil and the magnetic part are all arranged in the installation cavity; the mainboard is connected to the wireless charging coil, and the mainboard is also used to connect to an external wiring material; the magnetic part adsorption part is arranged in the installation cavity, and the magnetic part is magnetically adsorbed to the magnetic part adsorption part; the magnetic part can be flipped in the installation cavity when subjected to an external magnetic repulsive force, and adsorb the device to be charged with a side opposite to the magnetic pole polarity of the device to be charged placed on the outer surface of the face shell. The above-mentioned magnetic pole adsorption type wireless charger, through the cooperation of the magnetic part and the magnetic adsorption part, is conducive to providing an attachment carrier for the magnetic part to position the magnetic part, so as to relatively stably protect the magnetic part and help to enhance the magnetic adsorption force of the magnetic part; on the other hand, the magnetic part flips relative to the magnetic adsorption part under the state of magnetic repulsion, and flips in the installation cavity, which is conducive to the wireless charging coil to accurately align the device to be charged to achieve charging.

On the other hand, it is conducive to improving the charging efficiency of the wireless charging coil, and is also conducive to cooperating with the wireless charging coil to provide a higher power charging output. The following is combined with Figures 1 to 15 , the magnetic pole adsorption type wireless charger is described in detail.

[0054] In one embodiment, a magnetic pole adsorption type wireless charger 100 is as follows Figure 1 and Figure 2 As shown, it includes a face shell 110, a bottom shell 120, a mainboard 130, a wireless charging coil 140, a magnetic part 150 and a magnetic part adsorbing part 170; the face shell 110 and the bottom shell 120 together enclose a mounting cavity 160, and the mainboard 130, the wireless charging coil 140, the magnetic part 150 and the magnetic part adsorbing part 170 are all arranged in the mounting cavity 160; the mounting cavity 160 can be open or closed, and can be arranged according to actual needs. In this embodiment, a cylindrical mounting cavity 160 is shown. In other embodiments, the mounting cavity 160 can also be in other shapes, and the embodiments of the present application do not impose additional restrictions on this.

[0055] In each embodiment, the mainboard 130 is connected to the wireless charging coil 140. Figure 5, the mainboard 130 is also used to connect to the external wiring material 190, so as to access the external power supply through the external wiring material 190; that is, the external power supply is connected to the mainboard 130 through the external wiring material 190, and the mainboard 130 directly or indirectly supplies power to the wireless charging coil 140, that is, the external power supply directly or indirectly supplies power to the wireless charging coil 140 through the mainboard 130. Exemplarily, in one embodiment, the mainboard 130 and the external wiring material 190 are pluggable; in one embodiment, as Figure 3 and Figure 4 As shown, the front shell 110 or the bottom shell 120 is provided with a wire interface 114, so that the external wire 190 can be inserted into the installation cavity 160 and connected to the mainboard 130; illustratively, the external wire 190 is used to be pluggably connected to the mainboard 130 through the wire interface 114; or, the external wire 190 is used to be welded to the mainboard 130 through the wire interface 114. As an example, the mainboard 130 is provided with a USB port such as a USB-C port, and the external wire 190 is provided with a corresponding connection terminal, and the mainboard 130 and the external wire 190 can achieve electrical conduction when they are connected.

[0056] In one embodiment, if Figure 8 and Fig. 9 As shown, the magnetic pole adsorption type wireless charger 100 also includes the external wiring material 190. The mainboard 130 is connected to the external wiring material 190, and the power source is connected through the external wiring material 190, that is, the external power source is connected. That is, the magnetic pole adsorption type wireless charger 100 described in the present application can be made into a product without the external wiring material 190, and the external wiring material 190 can be connected when in use, or it can also be made into a product with the external wiring material 190, which can be flexibly adjusted according to the actual situation.

[0057] In each embodiment, the magnetic component adsorption component 170 is arranged in the installation cavity 160, and the magnetic component 150 is magnetically adsorbed to the magnetic component adsorption component 170; in this way, the magnetic component 150 can be provided with an attachment carrier through the magnetic component adsorption component 170 to position the magnetic component 150, thereby relatively stably protecting the magnetic component 150 and helping to enhance the magnetic adsorption force of the magnetic component 150, that is, the magnetic field strength; when the magnetic component 150 is subjected to the external magnetic repulsive force, it can be flipped relative to the magnetic adsorption component and the flipping is carried out in the installation cavity 160, and the device to be charged 200 is adsorbed with the side with the opposite polarity to the magnetic pole of the device to be charged 200 placed on the outer surface 111 of the face shell 110. As an example, the magnetic component 150 is movably disposed in the installation cavity 160, and the magnetic component adsorption component 170 is fixedly disposed in the installation cavity 160. When the magnetic component 150 is in a flipped state, the magnetic component adsorption component 170 maintains a constant position; that is, before, during, and after the magnetic component 150 is flipped, the magnetic component adsorption component 170 maintains a constant position. As an example, the magnetic component adsorption component 170 magnetically positions the magnetic component 150; and, when the magnetic component 150 is subjected to a magnetic repulsion force, that is, when subjected to a magnetic repulsion force from the device to be charged 200, the magnetic component 150 is separated from the magnetic component adsorption component 170 and flipped in the installation cavity 160, and after flipping, the magnetic repulsion state is changed to a magnetic attraction state. In this state, the original magnetic repulsion of the device to be charged 200 forms a magnetic attraction force for the flipped magnetic member 150. In this state, the magnetic member 150 is magnetically attracted to the magnetic member adsorption member 170, and is also magnetically attracted to the device to be charged 200. In this way, the magnetic member 150 is used to adsorb the device to be charged 200 with the side with opposite magnetic polarity, that is, the side that is magnetically attracted, when the device to be charged 200 is placed on the outer surface 111 of the face shell 110. If the magnetic member 150 is not subjected to the magnetic repulsion, that is, the device to be charged 200 can be magnetically attracted to the magnetic member 150 from the beginning, the magnetic member 150 does not need to be flipped, and the device to be charged 200 can be magnetically attracted while maintaining the state of being magnetically attracted to the magnetic member adsorption member 170. Therefore, no matter which magnetic direction the magnetic attraction of the device to be charged 200 is, the device to be charged 200 can be accurately magnetically adsorbed on the outer surface 111, so as to be wirelessly charged through the wireless charging coil 140.

[0058] In one embodiment, the magnetic member 150 has two opposite magnetic adsorption planes, and the magnetism of the two opposite magnetic adsorption planes is opposite. For example, the two magnetic adsorption planes are respectively the south pole and the north pole. Figure 2 and Figure 4As shown, the magnetic member 150 is drum-shaped; in other embodiments, the magnetic member 150 may also be cylindrical, elliptical or prism-shaped. The specific shape of the magnetic member 150 is varied, as long as it can be turned over in the mounting cavity 160 and can provide sufficient magnetic adsorption force for the device to be charged 200. As an example, Fig.12 and Fig.13 As shown, the magnetic member 150 is cylindrical. Such a structural design, in conjunction with the embodiment having the limiting member 121 and / or the limiting area 161, is conducive to realizing the flipping of the magnetic member 150 in a smaller space, thereby changing the side of the magnetic member 150 close to the outer surface 111, that is, changing the magnetism of the side of the magnetic member 150 close to the outer surface 111.

[0059] In various embodiments, the magnetic member 150 is a permanent magnet. For example, the magnetic member 150 includes a samarium cobalt magnet, a neodymium iron boron magnet, a ferrite magnet, an aluminum nickel cobalt magnet, or an iron chromium cobalt magnet, etc.; as an example, the magnetic member 150 is a magnet, that is, a permanent magnet containing iron. In one embodiment, as Figure 4 and Figure 5 As shown, the magnetic pole adsorption type wireless charger 100 is provided with a limiter 121 in the installation cavity 160, and the magnetic member 150 can be flipped and set in the limiter 121. In this embodiment, the limiter 121 is set on the bottom shell 120; in other embodiments, the limiter 121 can also be set under the surface shell 110. Such a structural design, by limiting the position of the magnetic member 150 by the limiter 121, is conducive to ensuring that the magnetic member 150 is located within a certain range in the installation cavity 160, thereby maintaining the relative position relationship between the magnetic member 150 and the wireless charging coil 140.

[0060] In one embodiment, if Figure 5 As shown, the face shell 110 cooperates with the bottom shell 120 to form a limited position area 161 in the installation cavity 160; the magnetic member 150 is accommodated in the limited position area 161 and can be flipped in the limited position area 161. Exemplarily, the face shell 110 cooperates with the limiting member 121 of the bottom shell 120 to form a limited position area 161 in the installation cavity 160. Such a structural design also limits the position of the magnetic member 150 in the installation cavity 160, which is conducive to maintaining the relative position relationship between the magnetic member 150 and the wireless charging coil 140.

[0061] In order to enhance the magnetic adsorption force of the magnetic member 150, in each embodiment, as Figure 4 and Figure 5As shown, the magnetic pole adsorption type wireless charger 100 also includes a magnetic component adsorption component 170, and the magnetic component adsorption component 170 is arranged under the outer surface 111 to magnetically position the magnetic component 150. In this embodiment, the magnetic component adsorption component 170 is an iron sheet, and the magnetic component 150 is a magnet. In other embodiments, the magnetic component adsorption component 170 can also be an iron ring, that is, an annular iron component, and the magnetic component adsorption component 170 can also be an incomplete annular adsorption body composed of iron blocks, that is, the magnetic component adsorption component 170 is an incomplete annular adsorption body composed of iron blocks, or the magnetic component adsorption component 170 can also be an incomplete circular adsorption body composed of iron blocks, etc., that is, the magnetic component adsorption component 170 is an incomplete circular adsorption body composed of iron blocks. In one embodiment, the magnetic component adsorption member 170 is disposed under the outer surface 111, and the distance between the magnetic component adsorption member 170 and the outer surface 111 is smaller than the distance between the magnetic component adsorption member 170 and the bottom shell 120; that is, the magnetic component adsorption member 170 is closer to the outer surface 111 of the face shell 110 relative to the bottom shell 120. In one embodiment, the magnetic component adsorption member 170 is adhered to the outer surface 111; in one embodiment, the magnetic component adsorption member 170 is disposed on the main board 130. Such a position design is conducive to the magnetic component adsorption member 170 cooperating with the magnetic member 150 to achieve magnetic field enhancement.

[0062] In one embodiment, if Figure 2 and Figure 5 As shown, the face shell 110 is provided with a boss 115 on its inner surface; and a fixing groove 113 is provided inside the boss 115, and the magnetic adsorption member 170 is disposed in the fixing groove 113; in this embodiment, the wireless charging coil 140 is buckled on the outer periphery of the boss 115. With such a structural design, the boss 115 can be used to place the magnetic adsorption member 170 and also to position the wireless charging coil 140, which is beneficial to improving the internal structural stability of the magnetic pole adsorption type wireless charger 100.

[0063] For the embodiment with the limiter 121 to be described below, as an example, the face shell 110 is provided with a boss 115 on its inner surface; and a fixing groove 113 matching with the limiter 121 is opened inside the boss 115, and the magnetic pole adsorption type wireless charger 100 also includes a magnetic member adsorption member 170 disposed in the fixing groove 113, and the magnetic member adsorption member 170 abuts against the limiter 121 to magnetically position the magnetic member 150 disposed in the limiter 121. With such a structural design, the position change of the magnetic member 150 forms a variable magnetic pole structure. Compared with the traditional structure, on the one hand, the magnetic member 150 adopts a drum shape, that is, a spherical surface cuts two planes up and down. The existence of the spherical surface facilitates the rotation of the magnetic member 150 itself, and changes the magnetism of the side close to the outer surface 111, that is, the direction of the magnetic pole, and the two planes are the fixed surfaces of the two magnetic poles, which facilitates the adsorption and fixing of the device 200 to be charged. On the other hand, by adding a magnetic adsorption component 170 between the magnetic component 150 and the outer surface 111 of the surface shell 110, the magnetic adsorption component 170 can increase the magnetism of the magnetic component 150; and the magnetic adsorption component 170 has the function of enhancing the magnetic force of the magnetic component 150. After the magnetic component 150 is adsorbed on the magnetic adsorption component 170, the overall magnetic force of the magnetic component 150 is also strengthened accordingly; this is because the magnetic adsorption component 170 is magnetized, and the magnetic field generated is superimposed on the original magnetic field, and the magnetic force will be much greater than before, so the electromagnetic component 150 is usually equipped with an iron core. On the other hand, the magnetic component adsorption member 170 is fixedly disposed in the installation cavity 160, or adhered to the inner surface of the surface shell 110, or disposed on the mainboard 130. When the charging device 200 is not placed, the magnetic component 150 will automatically be adsorbed on the magnetic component adsorption member 170, so that the position of the magnetic component 150 in the installation cavity 160 is limited, and it will not move and produce noise, and it also avoids collision and damage to the magnetic component 150.

[0064] In one embodiment, the magnetic pole adsorption type wireless charger 100 is provided with a stopper 121 protruding from the bottom shell 120; the magnetic member adsorption member 170 cooperates with the stopper 121 to form a limit area 161; the magnetic member 150 is accommodated in the limit area 161, and flips in the limit area 161 under the state of magnetic repulsion. In this embodiment, the main board 130 is buckled on the outer periphery of the limit area 161. For the embodiment with the fixing groove 113 and the stopper 121, as an example, the stopper 121 extends into the fixing groove 113 or the fixing groove 113 surrounds the stopper 121. Such a structural design is also conducive to limiting the position of the magnetic member 150. On the one hand, the limit member 121 provides a certain turning space for the magnetic member 150, ensuring that the device to be charged 200 is in a suitable charging position, thereby improving the charging efficiency of the wireless charging coil 140, and is also conducive to cooperating with the wireless charging coil 140 to provide a higher power charging output; on the other hand, the limit member 121 also plays a positioning role for the mainboard 130, which is conducive to improving the internal structural stability of the magnetic pole adsorption type wireless charger 100.

[0065] In one embodiment, if Figure 2 and Figure 5 As shown, the face shell 110 is provided with a fixing groove 113 under the outer surface 111, and the magnetic component adsorption member 170 is arranged in the fixing groove 113. In other embodiments, the magnetic component adsorption member 170 can be adhered to the outer surface 111; or, the magnetic component adsorption member 170 can also be arranged on the main board 130. Such a structural design is conducive to firmly defining the position of the magnetic component adsorption member 170. As mentioned above, when the device 200 to be charged is not placed, the magnetic component 150 and the magnetic component adsorption member 170 are magnetically adsorbed, thereby keeping the position of the magnetic component 150 unchanged. When the magnetic pole adsorption type wireless charger 100 is carried or moved, the position of the magnetic component 150 in the installation cavity 160 is fixed, so no sound is generated, thereby avoiding damage to the magnetic component 150 due to collision.

[0066] In one embodiment, if Figure 3 and Figure 5 As shown, the housing 110 is provided with a groove 112 on the outer surface 111, and the groove 112 is arranged corresponding to the charging range of the wireless charging coil 140. Fig.10 or Fig.11 , the groove 112 is used to place the device 200 to be charged. Such a structural design is conducive to coordinating the position of the wireless charging coil 140 and stably positioning the device 200 to be charged.

[0067] In one embodiment, if Figure 6As shown, the magnetic pole adsorption type wireless charger 100 also includes a battery 180 disposed in the mounting cavity 160, and the battery 180 is connected to the mainboard 130. For example, in one embodiment, the battery 180 is connected to the wireless charging coil 140 through the mainboard 130, and is used to wirelessly charge the device 200 to be charged through the wireless charging coil 140. For example, in one embodiment, the battery 180 is connected to the external wiring material 190 through the mainboard 130, and is used to connect to an external power source through the external wiring material 190 to charge the battery 180. For example, in one embodiment, the mainboard 130 is connected to an external power source through the external wiring material 190 to charge the battery 180, and at the same time, the device to be charged 200 is wirelessly charged through the wireless charging coil 140; or, the mainboard 130 is connected to an external power source through the external wiring material 190 to charge the battery 180, and at the same time, the wireless charging coil 140 is powered by the battery 180, and the device to be charged 200 is wirelessly charged with the power of the battery 180; in this state, the external power source indirectly powers the wireless charging coil 140 through the battery 180.

[0068] like Fig.12 and Fig.13 As shown, the magnetic member 150 has two opposite magnetic surfaces, one is the South Pole S and the other is the North Pole N. Sufficient flipping space is provided in the mounting cavity 160, so that the magnetic member 150 can be flipped in the mounting cavity 160, that is, in some cases, the magnetic member 150 has a state in which the South Pole S faces the device to be charged 200 on the outer surface 111, and can also have a state in which the North Pole N faces the device to be charged 200 on the outer surface 111 after flipping; and vice versa. Such a structural design is conducive to the wireless charging coil 140 provided in the mounting cavity 160 to accurately align with the device to be charged 200. Regardless of the magnetic direction of the magnetic attraction of the device to be charged 200, the magnetic member 150 can be magnetically attracted to the magnetic part of the device to be charged 200, thereby greatly improving the compatibility of wireless charging, and can be compatible with watches of various brands and models. And because the magnetic part 150 can accurately be magnetically attracted to the magnetic part of the device to be charged 200, the device to be charged 200 can be accurately magnetically adsorbed on the outer surface 111 of the face shell 110, so that the device to be charged 200 is located within a higher charging efficiency range or even a maximum charging efficiency range of the wireless charging coil 140, thereby improving the charging efficiency of the wireless charging coil 140 and also facilitating the wireless charging coil 140 to provide a higher power charging output.

[0069] In one embodiment, the magnetic pole adsorption type wireless charger 100 is a watch wireless charger. Take the device to be charged 200 as a wearable device as an example, in particular, the wearable device is a watch with a wireless charging function, the watch can be wirelessly charged through an external wireless charging coil. Since the watch is smaller in size than the mobile phone, the internal charging coil is also small, and the charging position is subject to certain restrictions. Therefore, it is more necessary to accurately position the wireless charging coil 140 of the magnetic pole adsorption type wireless charger 100. In the above embodiment, no matter whether the magnetic part of the watch used for magnetic attraction positioning is the South Pole S or the North Pole N relative to the outer surface 111, since the magnetic part 150 can be flipped in the mounting cavity 160, when the watch is close to the outer surface 111 of the face shell 110, if the side of the magnetic part 150 close to the outer surface 111 is magnetically attracted to the magnetic part of the watch, as an example, Fig.12 As shown, the magnetic part of the watch is the South Pole S relative to the outer surface 111, and the side of the magnetic part 150 close to the outer surface 111 is the North Pole N. The two are magnetically attracted to each other, so the magnetic part 150 is close to the magnetic part of the watch. Through the magnetic attraction force between the magnetic part 150 and the magnetic part of the watch, on the one hand, the charging position of the watch is ensured to be accurate so as to achieve wireless charging through the wireless charging coil 140; on the other hand, the watch is ensured to remain in the charging position without any new external force during the charging process.

[0070] On the contrary, if the side of the magnetic member 150 close to the outer surface 111 is magnetically repelled from the magnetic part of the watch, due to the relatively large mass of the watch and the force applied by the user, the magnetic member 150 will flip in the mounting cavity 160, so that the side of the magnetic member 150 that is magnetically attracted to the magnetic part of the watch is close to the outer surface 111, and then magnetically attracted to the magnetic part of the watch. As an example, Fig.14 As shown, the magnetic part of the watch is the south pole S relative to the outer surface 111, and the side of the magnetic member 150 close to the outer surface 111 is the south pole S. The two magnetic forces repel each other, so the magnetic member 150 itself flips in the installation cavity 160, turning to the side with the magnetic north pole N close to the outer surface 111. Fig.15 As shown, the magnetic member 150 is then magnetically attracted to the magnetic part of the watch, and the watch can be wirelessly charged through the wireless charging coil 140.

[0071] The magnetic pole adsorption type wireless charger 100 described in the above embodiment provides a variable magnetic pole structure for magnetic wireless charging of watches. This structure is compatible with watches of various brands. No matter which magnetic direction the magnetic attraction or magnetic part inside the watch is, the watch can be adsorbed on the magnetic pole adsorption type wireless charger 100, which greatly improves the compatibility of the magnetic pole adsorption type wireless charger 100. In this embodiment, the structural design of the magnetic pole adsorption type wireless charger 100, combined with the embodiment with the magnetic part adsorption part 170, can increase the magnetic attraction force of the magnetic part 150, and will not produce abnormal noise, which is more stable.

[0072] Next, continue to combine Figures 1 to 15 , an example is given to illustrate the magnetic pole adsorption type wireless charger 100. In one embodiment, the structure of the magnetic pole adsorption type wireless charger 100 mainly includes a face shell 110, a bottom shell 120, a main board 130, a wireless charging coil 140, a magnetic part 150, a magnetic part adsorption part 170 and an external wiring material 190; the outer shape of the face shell 110 is provided with a groove 112 for carrying a device 200 to be charged, such as a watch, so as to facilitate the stable placement of the watch; the wireless charging coil 140 is located below the face shell 110, which can wirelessly charge the watch, and the wireless charging coil 140 is electrically connected to the main board 130 below, and the main board 130 is connected to the external wiring material 190. The mainboard 130 is electrically connected to supply power; the magnetic component adsorption component 170 is fixed in the fixing groove 113 of the face shell 110 by gluing, and the bottom shell 120 is convexly provided with a limiting component 121 such as a rib, which is supported to the bottom of the magnetic component adsorption component 170, so that the middle of the face shell 110 is not easily deformed, and the automatic rotation of the magnetic component 150 is not affected; the magnetic component 150 is placed in the middle, and is automatically adsorbed on the magnetic component adsorption component 170 through one of the two magnetic adsorption planes, so that when the whole machine is not in use, the magnetic component 150 can be fixed by the magnetic component adsorption component 170 and will not shake at will.

[0073] When the magnetic pole adsorption type wireless charger 100 is in use, as an example, when the magnetic pole adsorption type wireless charger 100 is attached to the watch for the first time, when the magnetic pole of the watch attachment surface is different from the magnetic pole of the magnetic part 150 of the magnetic pole adsorption type wireless charger 100, it will be automatically adsorbed; when the magnetic pole of the watch attachment surface is the same as the magnetic pole of the magnetic part 150 of the magnetic pole adsorption type wireless charger 100, the two magnetic poles repel each other, that is, the side of the magnetic part 150 close to the outer surface 111 repel each other magnetically. Since the magnetic component 150 is small and light and can be flipped in the installation cavity 160, the magnetic component 150 inside the magnetic pole adsorption type wireless charger 100 will rotate 180° due to the force of magnetic repulsion between like poles, thereby changing the direction of its own magnetic pole. The magnetic pole of the rotated magnetic component 150 becomes different from that of the watch, that is, the side of the magnetic component 150 close to the outer surface 111 is magnetically attracted to the magnetic part of the watch, thereby achieving magnetic adsorption of the magnetic component 150 and the watch, and the entire variable magnetic pole process is completed; and after use, the magnetic component 150 is magnetically attracted to the magnetic component adsorption component 170, and if there is no new external force, it remains in the charging position.

[0074] When the magnetic pole adsorption type wireless charger 100 is attached to the watch for the second time, the magnetic member 150 does not need to be turned over, and the watch, i.e., the device to be charged 200 in this embodiment, can be adsorbed by the magnetically attractive side. With such a structural design, the magnetic pole adsorption type wireless charger 100 can be flipped in the installation cavity 160 through the magnetic part 150, which is conducive to the wireless charging coil 140 accurately aligning the device to be charged 200. No matter which magnetic direction the magnetic attraction of the device to be charged 200 is, the device to be charged 200, such as a wearable device, especially a watch, can be accurately magnetically adsorbed on the outer surface 111 of the face shell 110. On the one hand, the compatibility of wireless charging is greatly improved, and it can be compatible with watches of various brands and models; on the other hand, it is conducive to improving the charging efficiency of the wireless charging coil 140, and it is also conducive to cooperating with the wireless charging coil 140 to provide a higher power charging output; on the other hand, when the whole machine is not in use, for example, when the device to be charged 200 is not charged, the magnetic part 150 and the magnetic part adsorption part 170 are magnetically attracted and fixed under the face shell 110, and will not shake at will, thereby protecting the magnetic part 150.

[0075] When other devices to be charged 200 are used, such as watches or bracelets of other brands, the above process can be repeated to match the magnetic poles. The remaining embodiments are similar and will not be described in detail.

[0076] It should be noted that other embodiments of the present application also include a magnetic pole adsorption type wireless charger that can be implemented by combining the technical features in the above embodiments.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
