Description

Technical Field

[0001] This application relates to the field of electronic devices, and particularly to an electronic device. Background Art

[0002] With the development of electronic devices, users' demand for the thinning of electronic devices, such as mobile phones, is increasing day by day. However, as the thickness of the mobile phone becomes thinner, the thickness of the back glue used to fix the battery and the space for activating the back glue also decrease accordingly. The carrier for carrying the battery middle frame becomes thinner and its flatness and strength deteriorate, which will directly affect the activation of the battery back glue. Once the adhesiveness of the back glue cannot be effectively activated, it will affect the effective adhesion of the back glue to the battery and the safety of battery use. Summary of the Invention

[0003] In view of this, this application provides an electronic device to solve the problems of thinning of electronic devices and insecure battery fixation.

[0004] Some embodiments of this application provide an electronic device, including: a middle frame including a battery compartment for installing a battery assembly; a battery assembly disposed in the battery compartment; an adhesive member disposed between the inner surface of the battery compartment and the battery assembly, such that the battery assembly is bonded to the middle frame. The adhesive member includes: a first adhesive member disposed on the inner surface, the first adhesive member being a frame body and being a strip-shaped colloid with adhesiveness on both sides; a second adhesive member disposed at the space surrounded by the frame body, the second adhesive member being capable of transforming from a liquid state to a solid state and having an adhesive force.

[0005] The electronic device according to the embodiment of this application can better fix the battery through the design of the back glue around the dispensing. Moreover, the back glue itself has good supporting force, which can support a fixed space for the dispensing, limit the thickness after curing of the dispensing, and thus limit the overall thickness of the adhesive glue, which is beneficial to the thickness control of the mobile phone. At the same time, the uniform thickness of the glue can better fix the battery. In addition, the requirement for the flatness of the bottom plate during the dispensing forming process is low. Therefore, it is more conducive to the thinning design of the bottom plate.

[0006] As an embodiment of this application, the first adhesive member includes at least one sub-adhesive member located inside the frame body and dividing the frame body into a plurality of sub-frame bodies, and a second adhesive member is disposed in the space surrounded by each sub-frame body. This structure can strengthen the supporting effect in the z-axis direction, better limit the thickness of the dispensing structural member in the sub-frame body, and improve the fixation of the battery assembly.

[0007] As an embodiment of this application, the frame body of the first adhesive member is a polygonal structure.

[0008] As an embodiment of the present application, the first adhesive member of the polygonal structure is arranged around the edge of the bottom end surface of the inner surface. This structure is conducive to fixing the battery.

[0009] As an embodiment of the present application, each subframe is provided with a notch, the notch connects the inside and outside of the subframe, and the notch is arranged away from the side of the battery assembly with the positive and negative electrodes. Such a structure is conducive to protecting the positive and negative electrodes of the battery.

[0010] As an embodiment of the present application, the width of the notch is smaller than the length of the side where the notch is located, which can better protect the positive and negative electrodes of the battery.

[0011] As an embodiment of the present application, in a first direction, the thickness of the first adhesive member is greater than 0.03 mm and less than 0.10 mm, wherein the first direction is the thickness direction of the electronic device. This thickness can ensure both the adhesive force of the first adhesive member and the thickness of the entire electronic device.

[0012] As an embodiment of the present application, in the first direction, the thickness of the second bonding member is the same as the thickness of the first bonding member.

[0013] As an embodiment of the present application, the adhesive member includes a plurality of first adhesive members, and the plurality of first adhesive members are arranged along the second direction and / or the third direction of the bottom end surface of the inner surface, the first direction is different from the second direction, and the second direction and the third direction are respectively perpendicular to the first direction.

[0014] As an embodiment of the present application, the width of the space enclosed by the sub-frame along the first direction is 8-10 mm. This structure is more conducive to the bonding and fixing of the battery.

[0015] As an embodiment of the present application, a gap is provided between the second adhesive member and the first adhesive member. By providing the gap, the second adhesive member can be prevented from contacting or covering the first adhesive member before curing, thereby affecting the bonding force of the first adhesive member.

[0031] Embodiments of the present application:

[0032] Electronic device 100; Middle frame 110; Battery compartment 120; Bottom plate 121; Side wall 122; Auxiliary space 123; Battery assembly 130; Adhesive structure member 140; Frame body 141; Sub-bonding member 142; Sub-frame body 143; Notch 143a; Dispensing structure member 150. Detailed implementation manners

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0034] To facilitate the understanding of the technical solutions of the embodiments of the present application, the technical problems to be solved by the embodiments of the present application will be described first.

[0035] It should be noted that in the drawings of this article, the z-axis direction (corresponding to the third direction) in the coordinate system refers to the thickness direction of the mobile phone, the x-axis direction (corresponding to the second direction) refers to the width direction of the mobile phone, and the y-axis direction (corresponding to the third direction) refers to the length direction of the mobile phone. In some cases of this application, the second direction may intersect with the third direction but not be perpendicular, and this application does not make any limitations in this regard.

[0036] In some embodiments, the battery is mostly fixed by using an adhesive tape. The adhesive tape is a sticky tape or film. When fixing, the adhesive tape is attached to the bottom plate of the battery compartment, and then the battery is pressed on the adhesive tape to achieve the fixation of the battery.

[0037] Reference Figure 1 , Figure 1 shows a cross-sectional schematic diagram of an electronic device in some embodiments. As Figure 1 shown, the electronic device 10 includes a middle frame 11 and a battery 12. Among them, a battery compartment 15 is provided on the middle frame 11, and the bottom plate of the battery compartment is the bottom plate 14. The battery compartment 15 can be a part of the middle frame or can be formed by splicing an independent bottom plate 14 and the middle frame 11. The structure of the battery compartment 15 can be a rectangular groove with one end open. The rectangular groove matches the battery structure and can exactly accommodate the battery 12 therein, and the battery is fixed through the bottom surface and the surrounding surfaces. In addition, an adhesive tape 13 is provided between the battery 12 and the bottom plate 14. The larger side surface of the battery 12 is adhered to the surface of the bottom plate 14 of the battery compartment 15 through the adhesive tape 13, so that the battery 12 is firmly fixed in the battery compartment 15.

[0038] However, as the thickness design of electronic devices becomes thinner and thinner, that is, the space in the z-axis direction is continuously compressed. Since the adhesive force of the adhesive tape 13 requires a certain space to be activated. For example, in the natural state, the thickness of the adhesive tape 13 in the z-axis direction is 0.08 mm. It is necessary to apply pressure to the adhesive tape 13 to compress the adhesive tape 13 to about 0.05 mm in the z-axis direction before the adhesiveness of the adhesive tape 13 can be activated, so as to firmly fix the battery 12 on the structural member 11 of the battery compartment. Currently, the ultra-thin design of electronic devices makes it difficult to leave enough space in the z-axis direction to activate the adhesive tape 13, which will cause the adhesive force of the adhesive tape 13 to deteriorate, thus unable to effectively fix the battery 12.

[0039] In addition, in order to make the thickness of the electronic device thinner in the z-axis direction, the thickness of the bottom plate 14 of the battery compartment in the z-axis direction will also be designed to be thinner, which will cause the hardness of the bottom plate to deteriorate and affect the surface flatness. When the adhesive 13 is pasted to the battery 12, a part of the adhesive 13 may not be fully activated, so that the adhesive force of the adhesive 13 cannot be effectively activated, thereby affecting the fixation of the battery. If the thickness of the bottom plate 14 is not reduced, the overall design flexibility will be reduced. In addition, the traditional method of fixing the adhesive 13 also has the problem that the adhesive thickness is difficult to control and the bonding effect is poor, which seriously affects the stability and safety of the battery 12.

[0040] Based on the problems mentioned above, an embodiment of the present application provides an electronic device, which changes the traditional way of fixing the battery and the battery compartment, that is, the battery is bonded to the surface of the battery compartment by combining a back glue structure (first adhesive member) and a spot glue structure (second adhesive member). The back glue structure can not only predetermine the position of the battery relative to the base plate, but also serve as a supporting space in the z-axis direction to control the thickness of the spot glue structure. Not only can the battery be effectively bonded, but the structure can also reduce the strength and flatness requirements of the battery compartment, and the back glue can be thinned to save z-direction space, thereby improving the competitiveness of the overall machine thinning.

[0041] The structure of the electronic device according to the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0042] The electronic device of the embodiment of the present application may be, but is not limited to, a tablet personal computer, a straight-screen mobile phone, a folding screen mobile phone, a tablet computer, an e-book reader, a laptop computer, a personal digital assistant (PDA), a notebook, and other electronic devices. In the following embodiments, the electronic device is a mobile phone as an example for explanation.

[0043] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram showing the structure of an electronic device according to an embodiment of the present application. Figure 2As shown, the electronic device 100 includes a middle frame 110, a battery assembly 130, an adhesive structure member 140 (the first bonding member), and a dispensing structure member 150 (the second bonding member). Among them, the middle frame 110 includes a battery compartment 120 for installing the battery assembly 130. The battery compartment includes a bottom plate 121 forming the bottom of the battery compartment and side walls 122 around it. The battery assembly 130 is disposed in the battery compartment 120 and is surrounded and fixed by the bottom plate 121 and the side walls 122. In addition, the adhesive structure member 140 and the dispensing structure member 150 are disposed between the bottom plate 121 of the battery compartment 120 and the battery assembly 130, so that the battery assembly 130 is bonded within the battery compartment 120 of the middle frame 110.

[0044] As Figure 2 shown, the adhesive structure member 140 is disposed on the surface of the bottom plate 121 of the battery compartment 120. The adhesive structure member 140 is formed by a strip of tape surrounding a frame structure, and the adhesive structure member 140 is a double-sided adhesive strip-shaped colloid. For example, double-sided tape can bond the battery assembly 130 and the bottom plate 121 of the battery compartment together. The dispensing structure member 150 is disposed at the space surrounded by the frame. Among them, the dispensing structure member is a structure member formed after a low-modulus glue (dispensing glue) is cured. During fixation, the adhesive structure member 140 is pre-fixed on the surface of the bottom plate 121 of the battery compartment. The dispensing structure member 150 is in a liquid state before forming a solid layer structure. The dispensing glue is dropped into the frame surrounded by the adhesive structure member 140, and then the battery assembly 130 is placed in the battery compartment 120 so that the surface of the battery assembly 130 contacts the adhesive structure member 140 and the dispensing glue. A small force is applied to the battery assembly 130 to make the surface of the battery assembly 130 fully contact the adhesive structure member 140 and the dispensing glue. When the dispensing glue is cured to form the dispensing structure member 150, the bottom plate 121 of the battery compartment is directly fixedly connected to the battery assembly 130. Since the dispensing structure member 150 is formed by curing the liquid dispensing glue, the dispensing structure member 150 has a lower requirement for the flatness of the surface of the bottom plate 121, can achieve a thinner design of the bottom plate, and does not require a large space to apply pressure to activate the colloid, which is more conducive to saving the z-direction space. In addition, the cured dispensing structure member 150 has a strong bonding force and can firmly fix the battery assembly 130 in the battery compartment 120.

[0045] The mobile phone according to the embodiment of the present application, through the design method of surrounding the dispensing with the back glue, on the one hand, it can avoid the dispensing overflowing in the liquid state and flowing to the positive and negative electrodes of the battery, damaging the positive and negative electrodes of the battery. On the other hand, the back glue itself has good supporting force, which can support a fixed space for the dispensing and limit the thickness after the dispensing is cured, so as to limit the overall thickness of the bonding glue, which is beneficial to the thickness control of the mobile phone. At the same time, the uniform thickness of the glue can better fix the battery. In addition, the requirement for the flatness of the bottom plate 121 is low during the dispensing forming process. Therefore, it is more beneficial to the thinning design of the bottom plate 121.

[0046] Reference Figure 3 , Figure 3 shows a top view of the back glue structural member and the dispensing structural member according to the embodiment of the present application provided on the bottom plate of the battery compartment. As shown in FIG. 3, the back glue structural member 140 not only includes a large frame 141 surrounded by the tape (a frame structure surrounded along the edge of the bottom plate 121, referring to the frame 141 indicated by the dotted line), but also includes a sub-frame 143 divided by a plurality of sub-bonding members 142 (the sub-frame 143 indicated by the dotted line provided inside the frame 141). Among them, the sub-bonding member 142 is located inside the frame 141, so as to divide the frame 141 into a plurality of sub-frames 143. A dispensing structural member 150 is provided in each sub-frame 143. In this structure, since the large frame 141 is divided into a plurality of sub-frames 143, the sub-bonding members 142 of the sub-frames 143 can strengthen the supporting effect in the z-axis direction, better limit the thickness of the dispensing structural member 150 in the sub-frame 143, and can strengthen the fixation of the battery assembly.

[0047] As Figure 3 shown, a notch 143a is provided on each sub-frame 143, and the notch 143a communicates the inside of the sub-frame 143 with the outside. When the battery needs to be replaced, an organic solvent that is beneficial to the glue losing its viscosity, such as alcohol, can be injected through the notch 143a, so that the back glue structural member 140 and the dispensing structural member 150 lose their viscosity, and thus the battery can be quickly disassembled. In the embodiment of the present application, the notch 143a is provided away from the side with positive and negative electrodes of the battery assembly (such as Figure 2 the battery assembly 130) ( Figure 3 below the battery compartment 120 in

[0048] As Figure 3 shown, in order to better limit the liquid dispensing from flowing out of the notch 143a, the width of the notch 143a should be set narrower to meet the injection of the syringe for conveying the organic solvent. For example, the notch 143a only occupies a part of its corresponding side, so that a channel for inputting the organic solvent can be reserved, and the dispensing overflow can be avoided as much as possible.

[0049] Continue to refer Figure 3 The width w1 of the space enclosed by the subframe 143 in the x-axis direction is 8-10 mm, for example, 8.5 mm, 9 mm or 9.5 mm. This spacing can ensure that the frame 143 provides a strong enough support force for the glue dispensing in the z-axis direction, ensures that there is enough space to provide effective space for the thickness of the glue dispensing, and the appropriate distribution is conducive to the uniformity of the overall battery adhesion and the firmness of the battery adhesion.

[0050] like Figure 3 As shown, a gap w2 is provided between the adhesive backing structure 140 and the adhesive dispensing structure 150 in the x-axis direction. The spacing of w2 can be 0.5 mm, 0.1 mm, 1.5 mm or 2 mm, etc., and the present application does not limit this. By setting the gap w2, it is possible to prevent the adhesive dispensing from covering the adhesive backing structure 140 in liquid state, thereby affecting the thickness of the adhesive backing structure 140 in the z-direction and the pasting effect.

[0051] like Figure 3 As shown, an auxiliary space 123 slightly expanding outward is formed at at least one corner of the battery compartment. Because a release paper (not shown) is provided on the adhesive structure 140 of the battery compartment before the battery assembly is installed in the battery compartment 120, the release paper can better protect the adhesive and prevent dust from sticking to the adhesive and affecting the adhesive. By setting the auxiliary space 123, a part of the release paper can be extended to the auxiliary space 123, so that the whole piece of release paper can be torn off through this part of the release paper, which facilitates the operation of the pasting process and saves process time.

[0052] refer to Figure 4 , Figure 4 The cross-sectional view of the mobile phone of the embodiment of the present application is shown. Figure 4 The cross-sectional view in FIG. 1 is a front view of the mobile phone cut along the x-axis direction after the battery assembly 130 is installed in the battery compartment. Figure 4 As shown, in the z-axis direction, the thickness d1 of the adhesive backing structure 140 is greater than 0.03 mm and less than 0.10 mm. For example, it can be 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, 0.08 mm or 0.09 mm, etc. This thickness can ensure good adhesion, provide support space for the adhesive dispensing structure 150 before curing, and meet the thinness requirements of the mobile phone.

[0053] In some embodiments, in the z-axis direction, the thickness d2 of the adhesive dispensing structure 150 is the same as the thickness d1 of the adhesive backing structure 140. This ensures that the adhesives of both materials can be effectively adhered to the battery.

[0054] In the above embodiments, the adhesive structure member 140 includes a rectangular frame 141 and a plurality of rectangular sub - frames 143, and the sub - frames 143 divide the frame 141 along the y - axis direction of the mobile phone as an example for illustration. In other embodiments, the frame structure of the adhesive structure member 140 can be diverse, and the number can also be multiple. The following will further illustrate the structures of the adhesive structure member 140 and the dispensing structure member 150 with reference to the accompanying drawings by way of examples.

[0055] Reference Figure 5 , Figure 5 shows a schematic structural diagram of the adhesive structure member and the dispensing structure member of the first embodiment of the present application provided on the bottom plate of the battery compartment. As shown in FIG. 5, the frame 141 of the adhesive structure member 140 is formed by a tape surrounding the perimeter of the bottom plate 121, and the sub - adhesive members 142 extend along the x - axis direction of the mobile phone and divide the frame 141 into a plurality of sub - frames 143 (such as Figure 5 the part covered by the dotted line in the figure), and the dispensing structure member 150 is arranged within the sub - frame 143. This structure can meet the effective adhesion of the dispensing structure member 150 and the adhesive structure member 140 to the battery assembly.

[0056] Reference Figure 6 , Figure 6 shows a schematic structural diagram of the adhesive structure member and the dispensing structure member of the second embodiment of the present application provided on the bottom plate of the battery compartment. As Figure 6 shown, the frame 141 of the adhesive structure member is wound along the perimeter of the bottom plate 121, and the dispensing structure member 150 is arranged inside the frame 141. This large - area dispensing design has lower requirements for the flatness of the bottom plate 121, is conducive to the thinning of the bottom plate 121, and can firmly fix the battery assembly.

[0057] In some embodiments, the dispensing structure member 150 can be an integral body or multiple divided sub - blocks. Reference Figure 7 , Figure 7 shows a schematic structural diagram of the adhesive structure member and the dispensing structure member of the third embodiment of the present application provided on the bottom plate of the battery compartment. As Figure 7 shown in (a) of the figure, two dispensing structure members 150 can be arranged inside the frame 141 of the adhesive structure member, or as Figure 7 shown in (b) of the figure, four dispensing structure members 150 can be arranged inside the frame 141 of the adhesive structure member. The number of these dispensing structure members 150 can be adjusted according to process requirements, etc. In some embodiments, the dispensing structure member 150 can also be composed of some irregular structures, and the embodiments of the present application do not limit this.

[0058] In some embodiments, after the housing 141 is divided into sub-housings, a plurality of dispensing structure members 150 may be disposed in the sub-housings, or a plurality of back adhesive structure members 140 may be directly disposed on the bottom plate 121. A plurality of dispensing structure members 150 may be disposed inside the housing 141 surrounded by each back adhesive structure member.

[0059] Reference Figure 8 , Figure 8 FIG. shows a schematic structural diagram of a back adhesive structure member and a dispensing structure member disposed on the bottom plate of the battery compartment according to the fourth embodiment of the present application. As Figure 8 shown in (a), the housing 141 of the back adhesive structure member may be divided into two sub-housings 143, and two dispensing structure members 143 may be disposed in each sub-housing 143. Compared with the structure shown in Figure 7 , the structure shown in FIG. adds sub-bonding members 142, which can play a better supporting role. As Figure 8 shown in FIG., two back adhesive structure members 140 are disposed on the bottom plate 121, and a plurality of dispensing structure members 150 are disposed inside the housing of each back adhesive structure member 140. Compared with the structure shown in Figure 7 , increasing the number of sub-bonding members 142 or the number of the housing can ensure the pasting effect, and can play a better supporting role in the z-direction space, which is beneficial to the formation of the thickness of the dispensing structure member.

[0060] In other embodiments, there may be a plurality of back adhesive structure members 140, which are arranged along the surface of the bottom plate.

[0061] Reference Figure 9 , Figure 9 FIG. shows a schematic structural diagram of a back adhesive structure member and a dispensing structure member disposed on the bottom plate according to the fifth embodiment of the present application. As Figure 9 shown in FIG., two back adhesive structure members 140 are disposed on the bottom plate 121 of the battery compartment. The two back adhesive structure members are both rectangular frames, and a plurality of sub-bonding members are disposed inside the rectangular frame, dividing the rectangular frame into a plurality of sub-housings. Among them, the two back adhesive structure members 140 are arranged along the y-axis direction. As Figure 9 shown in (b), eight back adhesive structure members 140 are disposed on the bottom plate 121. The eight back adhesive structure members 140 are arranged along the x-axis direction and the y-axis direction. Among them, for the specific structure and deformation examples of each back adhesive structure member 140, reference may be made to the description in the above embodiments, and details are not listed here one by one.

[0062] In the above, the housing structure of the back adhesive structure member 140 is a rectangular structure, and the rectangular structure can just surround the edge of one side of the battery assembly, which is beneficial to the effective fixation of each corner and four sides of the battery. In other embodiments, the housing and sub-housing of the back adhesive structure member 140 may be other structures, for example, they may be polygonal structures such as triangles and pentagons, or circular structures.

[0063] Reference Figure 10 , Figure 10 shows a schematic structural diagram of the adhesive structure member and the dispensing structure member of the sixth embodiment of the present application disposed on the bottom plate. As Figure 10 shown, a rectangular frame 141 is provided on the bottom plate 121, and a sub-bonding member 142 is disposed on the diagonal of the frame 141. The sub-bonding member 142 divides the large frame 141 into two triangular sub-frames. This structure meets the requirement of effectively bonding and fixing the four sides and four corners of the battery, and the middle sub-bonding member 142 can not only strengthen the bonding effect but also provide a strong support in the z-axis space, which is beneficial to the uniformity of the dispensing thickness. In addition, a notch 143a is provided on one side of the sub-frame, and the side of the notch 143a away from the electrode of the battery assembly can prevent the dispensing from overflowing in the liquid state and damaging the battery.

[0064] Reference Figure 11 , Figure 11 shows a schematic structural diagram of the adhesive structure member and the dispensing structure member of the seventh embodiment of the present application disposed on the bottom plate. As shown in (a) of FIG. 11, two adhesive structure members 140 are provided on the bottom plate 121, and the two adhesive structure members 140 are arranged on the bottom plate 121. The frame 141 of the adhesive structure member 140 is a circular frame, and a notch 143a is provided on the circular frame. Correspondingly, the dispensing structure member 150 can also be a circular structure. As shown in (b) of FIG. 11, the shapes of the adhesive structure members on the same bottom plate 121 can be different. For example, it can be a rectangular frame or a combination of a circular frame. The present application does not limit this. In some embodiments, the frame structure can also be a pentagon or a polygon with more sides, or an irregular shape, etc., which can be changed and adjusted according to the needs of the internal structure of the mobile phone, as long as the adhesive structure member and the dispensing structure member are combined for use. Correspondingly, the dispensing structure member can also be a polygon or an irregular shape, and these can all achieve the fixation of the battery, and the embodiments of the present application do not limit this.

[0065] It should be noted that Figures 5 - 11 in the exemplary structure, for the settings of the notch, the gap between the dispensing structure member and the frame of the adhesive structure member, and the spacing in the x-axis direction or y-axis direction of the space surrounded by the sub-frame of the adhesive structure member, etc., the corresponding parameters, structures, and position settings can all refer to Figure 2 and Figure 3 the content explained, and will not be described one by one here.

[0066] In the above embodiments, the description is made by taking the example that the adhesive structure member 140 and the dispensing structure member 150 are attached to the surface of the bottom plate 121 of the battery compartment. In some embodiments, the adhesive structure member 140 and the dispensing structure member 150 can also be disposed on the inner surface of the side wall 122 of the battery compartment, which is more conducive to reducing the thickness of the whole machine. In other embodiments, the dispensing structure member 140 or the adhesive structure member 150 can also be disposed on both the surface of the bottom plate 121 and the inner surface of the side wall 122 of the battery compartment, which can strengthen the fixation of the battery.

[0067] In the electronic device according to the embodiment of the present application, the battery is bonded and fixed by combining the adhesive structure member and the dispensing structure member. Not only can the battery be firmly fixed, but the adhesive can also be used as a support structure to control the thickness of the dispensing in the z direction, so that the battery is effectively bonded. In addition, since a low-modulus glue is used for dispensing, during fixation, the dispensing will not affect the pasting effect of the dispensing structure member due to the flatness of the inner surface of the battery compartment. Thus, the bottom plate of the battery compartment can be made thinner, which is conducive to adjusting the overall thickness. And the dispensing does not require sufficient z-direction space to activate the bonding force, further saving the z-direction space.

[0068] It should be noted that the mutual parallelism in the present application is not absolute parallelism. The approximate parallelism caused by processing errors and assembly errors (for example, the included angle between two structural features is 0.1°) is also within the scope of the mutual parallelism in the present application. The axial symmetry in the present application is not absolute axial symmetry. The approximate axial symmetry caused by processing errors and assembly errors (for example, a part of the structure deviates from the axis of symmetry by a certain distance or angle) is also within the scope of the axial symmetry in the present application. The central symmetry in the present application is not absolute central symmetry. The approximate central symmetry caused by processing errors and assembly errors (for example, a part of the structure deviates from the axis of symmetry by a certain distance or angle) is also within the scope of the central symmetry in the present application. The present application does not make specific limitations on this.
