Description

Technical Field

[0001] This application belongs to the field of camera technology, specifically relating to a camera module and its installation method, and electronic equipment. Background Technology

[0002] With the expansion of electronic device functions, many electronic devices have added camera modules to take pictures.

[0003] In related technologies, a camera module includes at least two lens groups arranged sequentially. At least one lens group has a fixed position and can be driven to move to adjust the focal length of the camera module. Each lens group needs to be manufactured and tested independently, resulting in high production costs and significant testing difficulties. Furthermore, each lens group includes a lens barrel and a lens element, with the lens element installed within the corresponding lens barrel. After processing, each lens group needs to be assembled, but the assembly process is complex and challenging. Moreover, the relative positions of the lenses in different lens groups after assembly are crucial, and positional deviations can easily occur after assembly, thus affecting the camera module's imaging performance. Summary of the Invention

[0004] The purpose of this application is to provide a camera module and its installation method and electronic device, which can solve the problem in the related art that the lens groups of the camera module are prone to positional deviation after assembly, thus affecting the camera performance.

[0005] In a first aspect, embodiments of this application provide a camera module, including a lens barrel, a first lens, and a second lens. The lens barrel includes a first cylindrical portion, a connecting portion, and a second cylindrical portion that are sequentially connected and integrally formed. The first lens is disposed within the first cylindrical portion, and the second lens is disposed within the second cylindrical portion. The first lens and the first cylindrical portion form a first lens group, and the second lens and the second cylindrical portion form a second lens group.

[0006] The connecting part is a fractured structure. When the connecting part is subjected to external force, the connecting part is in a fractured state, so that the first cylinder and the second cylinder are separated.

[0007] Secondly, embodiments of this application also provide an electronic device, including a device housing and the aforementioned camera module, wherein the camera module is disposed on the device housing.

[0008] Thirdly, embodiments of this application also provide a method for installing a camera module, including:

[0009] A one-piece molded lens barrel is formed, the lens barrel comprising a first cylindrical section, a connecting section and a second cylindrical section connected in sequence;

[0010] The first lens is installed into the first cylindrical portion through the first mounting port, and the second lens is installed into the second cylindrical portion through the second mounting port, wherein the first mounting port is the port of the first cylindrical portion away from the second cylindrical portion, and the second mounting port is the port of the second cylindrical portion away from the first cylindrical portion;

[0011] Install the lens barrel;

[0012] A force is applied to the connecting portion to cause it to break, thereby separating the first cylindrical portion and the second cylindrical portion.

[0013] In this embodiment, the lens barrel of the camera module is a one-piece molded structure. Therefore, after the first and second lenses are installed into the lens barrel, the lens barrel can be directly installed, simplifying the assembly process and ensuring the accurate relative positions of the first and second lenses. That is, the relative positions of the lenses in the first lens group and the lenses in the second lens group are accurate, avoiding large positional deviations that could affect the imaging performance of the camera module. After the lens barrel is installed, the connecting part can break off, allowing the first and second barrel sections to separate. The first and second barrel sections can then move relative to each other to adjust the distance between the first and second lenses, achieving focusing. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] The following description, in conjunction with the accompanying drawings, details the camera module, its installation method, and electronic equipment provided in this application through specific embodiments and application scenarios.

[0028] refer to Figures 1-3 The camera module disclosed in this application includes a lens barrel 100, a first lens 200 and a second lens 300. The lens barrel 100 serves as the mounting base for the first lens 200 and the second lens 300, and the first lens 200 and the second lens 300 are respectively mounted inside the lens barrel 100.

[0029] Specifically, refer to Figure 1 As shown, the lens barrel 100 includes a first barrel portion 110, a connecting portion 120, and a second barrel portion 130 that are sequentially connected and integrally formed. A first lens 200 is disposed within the first barrel portion 110, and a second lens 300 is disposed within the second barrel portion 130. Specifically, the first barrel portion 110 forms a first chamber, which serves as a mounting chamber for the first lens 200, and the first lens 200 is disposed within the first chamber. The second barrel portion 130 forms a second chamber, which serves as a mounting chamber for the second lens 300, and the second lens 300 is disposed within the second chamber. The number of first lenses 200 can be one or more, and the first lenses 200 and the first barrel portion 110 form a first lens group. The number of second lenses 300 can also be one or more, and the second lenses 300 and the second barrel portion 130 form a second lens group.

[0030] Optionally, the first cylindrical portion 110, the connecting portion 120, and the second cylindrical portion 130 are arranged sequentially along the axial direction of the lens barrel 100. The lens barrel 100 can be made of plastic, and the first cylindrical portion 110, the connecting portion 120, and the second cylindrical portion 130 can be formed into an integral structure by injection molding. Alternatively, the lens barrel 100 can be made of metal, and the first cylindrical portion 110, the connecting portion 120, and the second cylindrical portion 130 can be formed into an integral structure by casting. Of course, the lens barrel 100 can also be made of other materials.

[0031] Optionally, the structure and size of the first cylindrical portion 110 and the second cylindrical portion 130 may be the same or different. The connecting portion 120 may be a connecting strip, a connecting block, etc. The embodiments of this application do not limit the specific structure of the connecting portion 120, as long as it can connect the first cylindrical portion 110 and the second cylindrical portion 130, thereby realizing the integral molding process of the lens barrel 100.

[0032] This configuration requires only one lens barrel 100 to simultaneously mount the first lens 200 and the second lens 300, thus forming different lens groups. It eliminates the need to manufacture a separate lens barrel 100 for each lens group, reducing the number of lens barrels 100 required and saving production costs. Furthermore, the one-piece molding of the lens barrel 100 simplifies the manufacturing process. Once the first lens 200 and the second lens 300 are mounted to the lens barrel 100, the lens barrel 100 can be directly installed, simplifying the assembly process and ensuring accurate relative positions of the first lens 200 and the second lens 300. This ensures accurate relative positions between the lenses in the first and second lens groups, preventing significant positional deviations after installation that could affect the camera module's imaging performance.

[0033] In addition, each lens group needs to be tested. Since this case uses a lens barrel of 100, only the camera module needs to be tested once, which reduces the number of tests and helps to reduce the difficulty of testing.

[0034] The connecting portion 120 is a fracture-resistant structure. When the connecting portion 120 is subjected to external force, it is in a broken state, thereby separating the first cylindrical portion 110 and the second cylindrical portion 130. Optionally, the connecting portion 120 can be a plastic or metal structure. It can be broken by cutting, such as laser cutting or ultrasonic cutting, with the external force coming from the cutting force. Alternatively, it can be broken by etching, with the external force being the etching force. Of course, other methods that can break the connecting portion 120 can also be used to achieve the separation of the first cylindrical portion 110 and the second cylindrical portion 130.

[0035] With this configuration, after the lens barrel 100 is installed, the connecting part 120 can break off, allowing the first barrel part 110 and the second barrel part 130 to separate. The first barrel part 110 and the second barrel part 130 can move relative to each other to adjust the distance between the first lens 200 and the second lens 300, thereby achieving focusing.

[0036] In one optional embodiment, the connecting portion 120 may be a connecting ring, with a first end of the connecting ring connected to the first cylindrical portion 110 and a second end of the connecting ring connected to the second cylindrical portion 130.

[0037] In another embodiment, the connecting portion 120 includes a connecting rib, which is a strip-shaped structure. The first end of the connecting rib is connected to the first cylindrical portion 110, and the second end of the connecting rib is connected to the second cylindrical portion 130.

[0038] In this embodiment, the connecting rib has a smaller volume, which helps to reduce the fracture area and shorten the fracture time. After the lens barrel 100 is installed, it is more conducive to the rapid separation of the first barrel 110 and the second barrel 130.

[0039] In one alternative embodiment, the number of connecting ribs is one.

[0040] In another embodiment, multiple connecting ribs are spaced apart along the circumference of the lens barrel 100. Optionally, the multiple connecting ribs can be evenly or unevenly distributed along the circumference of the lens barrel 100, and the structure of each connecting rib can be the same or different. In this embodiment, there are two connecting ribs, which are arranged opposite each other. Of course, the number of connecting ribs can also be set to other quantities.

[0041] In this embodiment, the number of connecting ribs increases, and the area where the first cylindrical portion 110 and the second cylindrical portion 130 are connected by the connecting ribs increases, which is beneficial to making the connection between the first cylindrical portion 110 and the second cylindrical portion 130 more stable.

[0042] In an optional embodiment, refer to Figure 1 As shown, the connecting portion 120 is provided with a marking structure 121 for indicating the fracture location. Optionally, the marking structure 121 can be a scale line, a marking groove, or other structures. This application embodiment does not limit the specific form of the marking structure 121, as long as it can indicate the fracture location.

[0043] Alternatively, when the marking structure 121 is a marking groove, the marking groove can be formed directly during the production of the lens barrel 100; when the marking structure 121 is a scale line, the marking can be done manually after the lens barrel 100 is produced.

[0044] By using this embodiment, the marking structure 121 helps to accurately determine the fracture location and ensures the accuracy of the fracture location.

[0045] Of course, in other embodiments, the connecting portion 120 may not have the marking structure 121, and the connecting portion 120 may be broken at any position to separate the first cylindrical portion 110 and the second cylindrical portion 130.

[0046] In one optional embodiment, the connection point between the connecting portion 120 and the first cylindrical portion 110 is the first connection point, and the connection point between the connecting portion 120 and the second cylindrical portion 130 is the second connection point. The marking structure 121 is located between the first connection point and the second connection point. The size of the connecting portion 120 is constant along the direction from the first connection point to the marking structure 121, and along the direction from the second connection point to the marking structure 121. Optionally, the size of the connecting portion 120 does not change along the axial direction of the lens barrel 100.

[0047] It should be noted that the dimension of the connecting part 120 refers to the dimension in the direction perpendicular to the axis of the lens barrel 100. Optionally, the connecting part 120 is a connecting rib, and there are two connecting ribs. In this case, the dimension of the connecting part 120 refers to the dimension in the direction in which the two connecting ribs are set.

[0048] In another embodiment, the size of the connecting portion 120 decreases along the direction from the first connection to the marking structure 121 and along the direction from the second connection to the marking structure 121. That is, the closer to the first cylindrical portion 110, the larger the size of the connecting portion 120; similarly, the closer to the second cylindrical portion 130, the larger the size of the connecting portion 120; and the closer to the marking structure 121, the smaller the size of the connecting portion 120.

[0049] Optionally, the connecting part 120 may be provided with a groove, the groove including a first groove wall and a second groove wall connected together, the first groove wall and the second groove wall are respectively inclined relative to the axis of the lens barrel 100, and the marking structure 121 is located at the connection between the first groove wall and the second groove wall. Further optionally, the first groove wall and the second groove wall can be a plane or an arc surface.

[0050] In this embodiment, the size of the connecting part 120 at the marking structure 121 is relatively small. Breaking at the marking structure 121 results in a smaller breakage area, which helps to shorten the breakage time. After the lens barrel 100 is installed, it is more conducive to the rapid separation of the first barrel part 110 and the second barrel part 130.

[0051] In one optional embodiment, the port of the first barrel 110 away from the second barrel 130 is a first mounting port 110a, and the port of the second barrel 130 away from the first barrel 110 is a second mounting port 130a. The first lens 200 can be disposed within the first barrel 110 through the first mounting port 110a, and the second lens 300 can be disposed within the second barrel 130 through the first mounting port 110a. Alternatively, the first lens 200 can be disposed within the first barrel 110 through the second mounting port 130a, and the second lens 300 can be disposed within the second barrel 130 through the second mounting port 130a. That is, the first lens 200 and the second lens 300 can be mounted from the same side of the lens barrel 100.

[0052] In another embodiment, the first lens 200 is disposed within the first barrel 110 through the first mounting port 110a, and the second lens 300 is disposed within the second barrel 130 through the second mounting port 130a. That is, the first lens 200 and the second lens 300 are respectively mounted from both sides of the lens barrel 100.

[0053] In this embodiment, the first mounting port 110a is closer to the mounting position of the first lens 200, and the second mounting port 130a is closer to the mounting position of the second lens 300. Therefore, the first lens 200 and the second lens 300 are mounted using the first mounting port 110a and the second mounting port 130a, respectively. The first lens 200 does not need to be mounted to the first barrel 110 from the second mounting port 130a via the connecting part 120, and the second lens 300 does not need to be mounted to the second barrel 130 from the first mounting port 110a via the connecting part 120. This makes the mounting process of the first lens 200 and the second lens 300 more convenient, and avoids the mounting process of the first lens 200 and the second lens 300 from affecting the connecting part 120.

[0054] In one optional embodiment, the port of the first cylindrical portion 110 near the second cylindrical portion 130 is designated as the first port 110b, and the diameter of the first mounting port 110a can be equal to the diameter of the first port 110b.

[0055] In another embodiment, the diameter of the first mounting port 110a is larger than the diameter of the first port 110b. Optionally, refer to... Figures 1-3 As shown, the inner wall surface of the first cylindrical portion 110 can be a conical surface or a stepped surface. The inner wall surface of the first cylindrical portion 110 can also be set to other structures, as long as the diameter of the first mounting port 110a is larger than the diameter of the first port 110b.

[0056] Optionally, the cross-sectional shape of the inner wall of the first barrel 110 can be a circular structure along the direction perpendicular to the axis of the lens barrel 100, and the first lens 200 is a circular lens. Of course, the cross-sectional shape of the inner wall of the first barrel 110 can also be other structures, and this application embodiment does not limit this.

[0057] In this embodiment, the diameter of the first mounting port 110a is larger, which makes it easier for the first lens 200 to extend into the first cylindrical part 110 and realize the installation process of the first lens 200.

[0058] In one optional embodiment, the port of the second cylindrical portion 130 closest to the first cylindrical portion 110 is designated as the second port 130b, and the diameter of the second mounting port 130a is equal to the diameter of the second port 130b.

[0059] In another embodiment, the diameter of the second mounting port 130a is larger than the diameter of the second port 130b. Optionally, refer to... Figures 1-3 As shown, the inner wall surface of the second cylindrical part 130 can be a conical surface or a stepped surface. The inner wall surface of the second cylindrical part 130 can also be set to other structures, as long as the diameter of the second mounting port 130a is larger than the diameter of the second port 130b.

[0060] Optionally, the cross-sectional shape of the inner wall of the second barrel 130 can be a circular structure along the direction perpendicular to the axis of the lens barrel 100, and the second lens 300 is a circular lens. Of course, the cross-sectional shape of the inner wall of the second barrel 130 can also be other structures, and this application embodiment does not limit this.

[0061] In this embodiment, the second mounting port 130a has a larger diameter, which makes it easier for the second lens 300 to extend into the second cylindrical part 130 and realize the installation process of the second lens 300.

[0062] In an optional embodiment, the camera module further includes a spacer 400, which is used to separate adjacent lenses and improve imaging stray light caused by lens edges. There are multiple first lenses 200, and the multiple first lenses 200 and the first cylindrical portion 110 form a first lens group. The first lenses 200 are spaced apart along the axial direction of the first cylindrical portion 110. A spacer 400 is provided between two adjacent first lenses 200 to separate the two adjacent first lenses 200. There are multiple second lenses 300, and the multiple second lenses 300 and the second cylindrical portion 130 form a second lens group. The second lenses 300 are spaced apart along the axial direction of the second cylindrical portion 130. A spacer 400 is provided between two adjacent second lenses 300 to separate the two adjacent second lenses 300.

[0063] Based on the camera module disclosed in this application, this application also discloses an electronic device. The connecting rib electronic device includes a device housing and the aforementioned camera module. The camera module is disposed in the device housing to realize the camera function of the electronic device. Of course, in addition to the device housing and camera module, the electronic device may also include functional components such as circuit boards and sensors.

[0064] In this embodiment, the camera module of the electronic device uses a one-piece molded lens barrel 100 to mount the first lens 200 and the second lens 300 respectively. After the lens barrel 100 is installed, the relative positions of the first lens 200 and the second lens 300 are accurate, avoiding large positional deviations that could affect the camera module's imaging performance. Moreover, after the lens barrel 100 is installed, the connecting part 120 can break off, allowing the first barrel portion 110 and the second barrel portion 130 to separate. The first barrel portion 110 and the second barrel portion 130 can move relative to each other to adjust the distance between the first lens 200 and the second lens 300, achieving focusing without affecting the camera module's imaging function.

[0065] In addition, each lens group needs to be tested. Since this case uses a lens barrel of 100, only the camera module needs to be tested once, which reduces the number of tests and helps to reduce the difficulty of testing.

[0066] In one alternative embodiment, the first cylindrical portion 110 is movable relative to the second cylindrical portion 130, and focusing can be achieved by manually adjusting the position of the first cylindrical portion 110 relative to the second cylindrical portion 130.

[0067] In another embodiment, reference Figure 2 and Figure 3 As shown, the electronic device also includes a drive mechanism 500, which includes a drive fixing member 510 and a drive moving member 520. The drive moving member 520 is movable relative to the drive fixing member 510. A first cylindrical portion 110 is connected to the drive moving member 520, and a second cylindrical portion 130 is connected to the drive fixing member 510. Optionally, the first cylindrical portion 110 and the drive moving member 520 can be fixedly connected by adhesive, welding, or other methods; the second cylindrical portion 130 and the drive moving member 520 can be fixedly connected by adhesive 511. Of course, the two can also be fixedly connected by welding or other methods.

[0068] The driving fixed member 510 interacts with the driving movable member 520. The driving movable member 520 moves relative to the driving fixed member 510 so that the driving movable member 520 drives the first barrel 110 to move relative to the second barrel 130 along the axial direction of the lens barrel 100, thereby adjusting the distance between the first lens 200 and the second lens 300 to achieve focusing of the camera module.

[0069] Optionally, the drive mechanism 500 can be a zoom motor, which may include a magnetic component and a coil. When the coil is energized, it generates a magnetic field, and the magnetic component experiences a Lorentz force in the magnetic field, causing relative motion between the magnetic component and the coil. When the position of the coil is fixed, the coil drives the fixed component 510, and the magnetic component drives the movable component 520; when the position of the magnetic component is fixed, the coil drives the movable component 520, and the magnetic component drives the fixed component 510. Of course, the zoom motor may also use a structure other than a magnetic component and a coil to drive the first cylindrical section 110, and the drive mechanism 500 may also use other drive components besides a zoom motor.

[0070] In addition, the zoom motor also includes a housing 530, a drive fixing member 510 and a drive moving member 520, all of which are disposed in the housing 530. The housing 530 is also provided with an inlet 531. A reflector 700 is provided inside the housing 530. The reflector 700 can be, but is not limited to, a prism. The light-incident surface of the reflector 700 is opposite to the inlet 531, and the light-exit surface of the reflector 700 is opposite to the second barrel 130. A photosensitive chip is provided on the side of the lens barrel 100 facing away from the reflector 700. In this way, light enters the housing 530 through the inlet 531 and passes through the reflector 700, the second lens 300 and the first lens 200 in sequence to finally reach the photosensitive chip to achieve imaging.

[0071] In this embodiment, the camera module is directly installed inside the drive mechanism 500. Different components of the drive mechanism 500 are connected to the first cylinder 110 and the second cylinder 130 respectively. The drive movable part 520 drives the first cylinder 110 to move relative to the second cylinder 130, which helps the first cylinder 110 to move quickly to the focusing position and achieve fast focusing without manual focusing.

[0072] In an optional embodiment, refer to Figure 2 and Figure 3 As shown, the electronic device also includes a guide rail 610 and a guide member. One of the housing 530 and the first cylindrical portion 110 is provided with the guide rail 610, and the other of the housing 530 and the first cylindrical portion 110 is connected to the guide member. The extending direction of the guide rail 610 is parallel to the axial direction of the lens barrel 100, and the guide rail 610 and the guide member provide a guiding fit. This arrangement, using the guide rail 610 and the guide member, guides the movement direction of the first cylindrical portion 110, facilitating accurate movement of the first cylindrical portion 110 relative to the second cylindrical portion 130 along the axial direction of the lens barrel 100, and accurately adjusting the focal length of the camera module.

[0073] Optionally, the other of the housing 530 and the first cylindrical portion 110 is provided with an arc-shaped groove. The guide member can be a ball bearing 620. A first part of the ball bearing 620 is located in the arc-shaped groove, and the other part of the ball bearing 620 extends into the guide rail 610. When the first cylindrical portion 110 moves relative to the second cylindrical portion 130, the ball bearing 620 rolls in the arc-shaped groove. The position of the ball bearing 620 relative to the arc-shaped groove is fixed, and the ball bearing 620 rolls in the guide rail 610. In this way, the friction between the ball bearing 620 and the guide rail 610 is rolling friction, which is relatively small and facilitates the smoother movement of the first cylindrical portion 110 relative to the second cylindrical portion 130.

[0074] The electronic devices disclosed in this application can be smartphones, tablets, e-book readers, wearable devices, video game consoles, etc. This application does not limit the specific types of electronic devices.

[0075] Based on the camera module disclosed in this application, embodiments of this application also disclose a method for installing the camera module, specifically including:

[0076] S100: A one-piece lens barrel 100 is formed, comprising a first barrel portion 110, a connecting portion 120, and a second barrel portion 130 connected in sequence. Optionally, the lens barrel 100 may be made of plastic and formed into a one-piece lens barrel 100 by injection molding; or, the lens barrel 100 may be made of metal and formed into a one-piece lens barrel 100 by casting.

[0077] S200, Reference Figure 1 As shown, the first lens 200 is installed into the first barrel 110 through the first mounting port 110a, and the second lens 300 is installed into the second barrel 130 through the second mounting port 130a. The first mounting port 110a is the port of the first barrel 110 furthest from the second barrel 130, and the second mounting port 130a is the port of the second barrel 130 furthest from the first barrel 110. In other words, the first lens 200 and the second lens 300 are installed from opposite sides of the lens barrel 100.

[0078] The first mounting port 110a is closer to the mounting position of the first lens 200, and the second mounting port 130a is closer to the mounting position of the second lens 300. Therefore, the first lens 200 and the second lens 300 are installed using the first mounting port 110a and the second mounting port 130a respectively. The first lens 200 does not need to be installed to the first barrel 110 from the second mounting port 130a via the connecting part 120, and the second lens 300 does not need to be installed to the second barrel 130 from the first mounting port 110a via the connecting part 120. This makes the installation process of the first lens 200 and the second lens 300 more convenient, and avoids the installation process of the first lens 200 and the second lens 300 from affecting the connecting part 120.

[0079] S300, Mounting lens barrel 100. Optionally, the first barrel portion 110 and the second barrel portion 130 of the lens barrel 100 are respectively connected to different parts of the drive mechanism 500 of the electronic device. Specifically, the first barrel portion 110 is connected to a magnetic component, and the second barrel portion 130 is connected to a coil, thereby realizing the installation of the camera module.

[0080] S400: Apply a force to the connecting portion 120 to cause it to fracture, thereby separating the first cylindrical portion 110 and the second cylindrical portion 130. Optionally, the connecting portion 120 can be cut by laser cutting or ultrasonic cutting to break it apart and separate the first cylindrical portion 110 and the second cylindrical portion 130. In this case, the force is a cutting force. Alternatively, the connecting portion 120 can be broken by etching to separate the first cylindrical portion 110 and the second cylindrical portion 130. In this case, the force is an etching force.

[0081] Using the above installation method, the first lens 200 and the second lens 300 are first installed into the same lens barrel 100, and then the connecting part 120 of the lens barrel 100 is broken, thereby forming a first lens group and a second lens group. The first lens group and the second lens group can move relative to each other to adjust the distance between the first lens 200 and the second lens 300 to achieve focusing. In this way, only one lens barrel 100 needs to be produced, which helps to save production costs. After the camera module is installed, the installation position of the first lens 200 and the second lens 300 is ensured to be accurate, avoiding large positional deviations that would affect the imaging performance of the camera module. In addition, each lens group needs to be tested. Since this case uses one lens barrel 100, the camera module only needs to be tested once, reducing the number of tests and helping to reduce the difficulty of testing.

[0082] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
