Description

Foot pad assembly, compressor and refrigeration equipment

[0001] The present application claims priority to the Chinese patent application No. 2024106543594, filed on May 22, 2024, entitled "Foot pad assembly, compressor and refrigeration equipment", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of compressors, in particular to a foot pad assembly, a compressor and a refrigeration equipment. BACKGROUND

[0003] As a core component of a refrigerator system, a compressor is generally installed on the bottom plate of the refrigerator system through the foot pad at the bottom, so that the vibration generated by the compressor during operation is transmitted to the bottom plate of the refrigerator system through the foot pad. At present, the compressor foot pad is usually made of rubber. During the operation of the compressor, the absorption and release of vibration energy by the rubber pad depend on the flexibility and hardness of the rubber pad. If the hardness of the rubber pad is low, the rubber pad has strong ability to suppress the vibration of the refrigerator system. However, since the mass of the compressor is completely supported by the rubber pad, the rubber pad that is too soft will deform or even be crushed during the long-term operation of the refrigerator, thereby reducing the damping effect of the rubber pad.

[0004] Therefore, how to design a foot pad assembly capable of improving the damping effect has become a problem to be solved at present. TECHNICAL SOLUTION

[0005] The present application aims to at least solve the problem of poor damping effect of the compressor.

[0006] To this end, the first aspect of the present application provides a foot pad assembly.

[0007] The second aspect of the present application provides a compressor.

[0008] The third aspect of the present application provides a refrigeration equipment.

[0009] Therefore, the first aspect of the present application provides a foot pad assembly, which comprises: a first elastic member, the first elastic member having a first accommodating cavity; a second elastic member, the second elastic member being arranged in the first accommodating cavity and being arranged in close contact with the inner wall of the first accommodating cavity; and a support portion, the support portion being arranged on the first elastic member or the second elastic member and being used for supporting a supported object. When the support portion supports the supported object, the first elastic member and the second elastic member can elastically deform, and the elastic deformation amounts of the first elastic member and the second elastic member are different.

[0010] The foot pad assembly provided by the application comprises a first elastic member and a second elastic member. The first elastic member has a first accommodating cavity, so that the second elastic member can be arranged in the first accommodating cavity and abut against the inner wall of the first accommodating cavity. It can be understood that the first elastic member and the second elastic member are arranged in a nested manner, the first elastic member is arranged on the outside, and the second elastic member is arranged on the inside. When the support part supports the supported object under force, the first elastic part and the second elastic part can realize vibration reduction, so as to prevent the supported object from being damaged due to strong vibration. Since the first elastic member and the second elastic member can elastically deform along the direction of the force when the force is applied, and the elastic deformation amount of the first elastic member and the second elastic member is different, a slight displacement will be generated between the first elastic member and the second elastic member, that is, one of the first elastic member and the second elastic member will elastically deform first, so that a slight friction is generated between the two elastic members, thereby dissipating the vibration energy and improving the vibration reduction effect. It can be understood that since the frequency of vibration is high, the friction frequency between the two elastic members is also high, so that the friction between the two elastic members can effectively reduce the vibration energy. Compared with the scheme in the related art in which the elastic members of the foot pad assembly are of an integral structure or the scheme in which a reinforcing structure is arranged, the application utilizes the friction generated by the mutual movement between the two objects, so that the vibration is reduced by the frictional resistance, and the vibration energy is effectively reduced.

[0011] Meanwhile, since the support part is arranged on the first elastic member or the second elastic member, one of the first elastic member and the second elastic member can first bear the force generated by the vibration, so that one of the first elastic member and the second elastic member can first elastically deform, so that a slight displacement can be generated relative to the other of the first elastic member and the second elastic member, and then the friction reduces the vibration energy.

Embodiments of the present application

[0039] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0040] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0041] The foot pad assembly, the compressor and the refrigeration device according to some embodiments of the present application will be described below with reference to Figs. 1-9.

[0042] According to one embodiment of the first aspect of the present application, as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 8, FIG. 9, the first aspect of the present application provides a foot pad assembly 1, comprising a first elastic member 10 and a second elastic member 12. The first elastic member 10 has a first accommodating cavity 100. The second elastic member 12 is arranged in the first accommodating cavity 100 and is arranged in close contact with the inner wall of the first accommodating cavity 100. A support part 102 is arranged on the first elastic member 10 or the second elastic member 12 and is used to support a supported object. When the support part 102 supports the supported object, the first elastic member 10 and the second elastic member 12 can elastically deform, and the elastic deformation amounts of the first elastic member 10 and the second elastic member 12 are different.

[0043] The foot pad assembly 1 provided by the present application comprises a first elastic member 10 and a second elastic member 12. The first elastic member 10 has a first accommodating cavity 100, so that the second elastic member 12 can be arranged in the first accommodating cavity 100 and arranged in close contact with the inner wall of the first accommodating cavity 100. It can be understood that the first elastic member 10 and the second elastic member 12 are arranged in a nested manner, the first elastic member 10 is arranged on the outside, and the second elastic member 12 is arranged on the inside. When the support part 102 supports the supported object under force, the first elastic part 120 and the second elastic part 122 can be used to realize vibration reduction, so as to prevent the supported object from being damaged due to strong vibration. Since the first elastic member 10 and the second elastic member 12 can elastically deform along the direction of the force when subjected to the force, and the elastic deformation amounts of the first elastic member 10 and the second elastic member 12 are different, a small displacement will be generated between the first elastic member 10 and the second elastic member 12, that is, one of the first elastic member 10 and the second elastic member 12 will elastically deform first, so that a small friction is generated between the two elastic members, so that the vibration energy can be dissipated, and the vibration reduction effect is improved. It can be understood that since the frequency of vibration is high, the friction frequency between the two elastic members is also high, so that the friction between the two elastic members can effectively reduce the vibration energy. Compared with the scheme in the related art in which the elastic member of the foot pad assembly 1 is of an integrated structure or the scheme in which a reinforcing structure is arranged, the present application utilizes the friction generated by the mutual movement between the two objects, so that the vibration energy is reduced by the frictional resistance, and the vibration energy is effectively reduced.

[0044] Meanwhile, since the support part 102 is arranged on the first elastic member 10 or the second elastic member 12, one of the first elastic member 10 and the second elastic member 12 can first bear the force generated by the vibration, so that one of the first elastic member 10 and the second elastic member 12 can first elastically deform, so that a small displacement can be generated relative to the other one of the first elastic member 10 and the second elastic member 12, and then the friction can reduce the vibration energy.

[0045] In some embodiments, the supported object comprises a compressor 2.

[0046] In some embodiments, the hardness of the first elastic member 10 is greater than the hardness of the second elastic member 12.

[0047] In this embodiment, the hardness of the first elastic member 10 is greater than the hardness of the second elastic member 12. In this way, when the first elastic member 10 is subjected to a certain degree of elastic deformation, it can drive the more flexible second elastic member 12 to be elastically deformed, which is more conducive to reducing vibration energy.

[0048] In some embodiments, the second elastic member 12 comprises a second accommodating cavity 126, and the foot pad assembly 1 further comprises a fixing member 14 arranged in the second accommodating cavity 126 and used for fixing the first elastic member 10 and the second elastic member 12 in a mounting position.

[0049] In this embodiment, the second elastic member 12 comprises a second accommodating cavity 126. The foot pad assembly 1 comprises a fixing member 14. In this way, the fixing member 14 can be arranged in the second accommodating cavity 126 and pass through the second accommodating cavity 126 and the first accommodating cavity 100, so as to fix the first elastic member 10 and the second elastic member 12 in a mounting position by using the second fixing member 14, thereby improving the mounting stability of the foot pad assembly 1. Moreover, since the fixing member 14 is arranged in the second accommodating cavity 126, the fixing member 14 can also be used to strengthen the strength of the second elastic member 12, thereby improving the stability of the second elastic member 12.

[0050] In some embodiments, the first accommodating cavity 100 comprises a first hole section 1000 and a second hole section 1002, the inner diameter of the first hole section 1000 is greater than the inner diameter of the second hole section 1002, and the inner wall of the second hole section 1002 abuts against the outer wall of the circumferential side of the fixing member 14; the outer wall of the fixing member 14 and the inner wall of the first hole section 1000 form a mounting space 104, and the second elastic member 12 is arranged in the mounting space 104.

[0051] In this embodiment, the first accommodating cavity 100 comprises a first hole section 1000 and a second hole section 1002. The inner diameter of the first hole section 1000 is larger than the inner diameter of the second hole section 1002, that is, the first accommodating cavity 100 is formed as a stepped hole. When the fixing member 14 is installed in the second accommodating cavity 126, the inner wall of the second hole section 1002 abuts against the outer wall of the circumferential side of the fixing member 14, that is, part of the fixing member 14 is arranged in the second hole section 1002 and extends out of the second accommodating cavity 126. Since the inner diameter of the first hole section 1000 is larger than the inner diameter of the second hole section 1002, when the inner wall of the second hole section 1002 abuts against the outer wall of the circumferential side of the fixing member 14, an installation space 104 is formed between the inner wall of the first hole section 1000 and the outer wall of the fixing member 14, and the second elastic member 12 can be arranged in the installation space 104. It can be understood that, by defining the installation space 104, the arrangement of the second elastic member 12 is facilitated, for example, liquid material can be injected into the installation space 104 by injection molding to form the second elastic member 12 after solidification, which is more conducive to forming the second elastic member 12 in various shapes, thereby maximizing the force requirement in actual application.

[0052] In specific implementation, as shown in FIG. 3, the fixing sleeve 140 can be first installed in the first accommodating cavity 100, and after the fixing sleeve 140 cooperates with the first elastic member 10, a closed installation space 104 is formed, liquid silicon rubber can be injected into the closed installation space 104 through the opening above the first elastic member 10, and the second elastic member 12 is formed in the installation space 104 after the liquid silicon rubber solidifies. The second elastic member 12 is not adhesively connected to the inner wall of the cavity, and therefore there is a slight displacement between the first elastic member 10 and the second elastic member 12, and the vibration energy generated during the operation of the compressor 2 can be dissipated through the slight displacement between the first elastic member 10 and the second elastic member 12.

[0053] In some embodiments, optionally, the second elastic member 12 is an injection molded member, and the shape of the injection molded member is matched with the shape of the installation space 104.

[0054] In this embodiment, the second elastic member 12 can be arranged as an injection molded member. The injection molded member is easy to process, convenient to arrange, and has high design flexibility, and can form various shapes, thereby maximizing the actual use requirement.

[0055] In some embodiments, optionally, the fixing member 14 comprises: a fixing sleeve 140 arranged in the second accommodating cavity 126; and a fixing screw 142 arranged in the fixing sleeve 140.

[0056] In this embodiment, the fixing member 14 comprises a fixing sleeve 140 and a fixing screw 142. The fixing sleeve 140 is arranged in the second accommodating cavity 126 and can constrain the first elastic member 10 and the second elastic member 12 in the radial direction of the second accommodating cavity 126 to limit the first elastic member 10 and the second elastic member 12. The fixing screw 142 is arranged in the fixing sleeve 140, so that the fixing screw 142 can be passed through the fixing sleeve 140 to fix the first elastic member 10 and the second elastic member 12 in the mounting position.

[0057] As shown in FIGS. 8 and 9, the lower end surface of the fixing screw 142 is in contact with the upper end surface of the fixing sleeve 140, and the fixing screw 142 fixes the fixing sleeve 140 on the bottom plate 3 of the refrigerator after being locked on the bottom plate 3 of the refrigerator. The top of the fixing sleeve 140 is 0.2 mm higher than the top of the first elastic member 10 and the second elastic member 12, which ensures that the fixing screw 142 does not directly contact the first elastic member 10 and the second elastic member 12 after being locked, and the fixing screw 142 does not generate vertical pressure on the foot pad assembly 1. As can be seen from FIG. 9, the fixing screw 142 does not directly lock the foot pad assembly 1, and the fixing screw 142 only serves to lock the fixing sleeve 140, which generates horizontal constraint on the first elastic member 10 and the second elastic member 12 but does not generate vertical constraint on the first elastic member 10 and the second elastic member 12.

[0058] In some embodiments, optionally, the length of the first elastic member 10 and the length of the second elastic member 12 are both less than the length of the fixing sleeve 140 in the first direction, and one end of the fixing sleeve 140 protrudes out of the first accommodating cavity 100 and the second accommodating cavity 126.

[0059] In this embodiment, the length of the first elastic member 10 and the length of the second elastic member 12 are both less than the length of the fixing sleeve 140 in the first direction, and one end of the fixing sleeve 140 protrudes out of the first accommodating cavity 100 and the second accommodating cavity 126, that is, the fixing sleeve 140 needs to protrude out of the first elastic member 10 and the second elastic member 12, so that the fixing sleeve 140 can be used for limiting when the fixing screw 142 is fixed, thereby avoiding the force generated by the fixing screw 142 from acting on the first elastic member 10 and the second elastic member 12 and ensuring the elasticity of the first elastic member 10 and the second elastic member 12.

[0060] In some embodiments, optionally, the protruding length of the fixing sleeve 140 is greater than or equal to 0.2 mm.

[0061] In this embodiment, the protruding length of the fixing sleeve 140 is greater than or equal to 0.2 mm. With this arrangement, the force generated by the fixing screw 142 when fixed can not act on the first elastic member 10 and the second elastic member 12, and material waste can be avoided, thereby reducing the cost.

[0062] In some embodiments, the protruding length of the fixing sleeve 140 is 0.2 mm.

[0063] In some embodiments, the protruding length of the fixing sleeve 140 is 0.4 mm.

[0064] In some embodiments, the protruding length of the fixing sleeve 140 is 0.6 mm.

[0065] In some embodiments, the support portion 102 is arranged on the first elastic member 10, and the support portion 102 comprises a support groove 1020 arranged on the circumferential side of the outer surface of the first elastic member 10, used to cooperate with the supported object to support the supported object.

[0066] In this embodiment, the support portion 102 is arranged on the first elastic member 10, and the support portion 102 can be a support groove 1020. The support groove 1020 is arranged on the circumferential side of the outer surface of the first elastic member 10, and can cooperate with the supported object to support the supported object. Specifically, a mounting hole can be arranged on the supported object, and then the support groove 1020 is clamped into the mounting hole, thereby realizing the fixation of the foot pad assembly 1 and the supported object.

[0067] As shown in FIG. 9, the base 20 of the compressor 2 is directly mounted on the support groove 1020, and the vibration generated by the operation of the compressor 2 is transmitted to the refrigerator bottom plate 3 after being attenuated by the foot pad assembly 1.

[0068] In some embodiments, the second accommodating cavity 126 comprises a first through hole 1260 and a second through hole 1262, the first through hole 1260 and the second through hole 1262 are in communication; the second elastic member 12 comprises a first elastic portion 120, the first through hole 1260 is arranged on the first elastic portion 120; a second elastic portion 122, arranged in the first through hole 1260, and the second through hole 1262 is arranged on the second elastic portion 122; an annular protruding rib 124 for connecting the second elastic portion 122 and the first elastic portion 120; the first elastic member 10 comprises a fixing groove 106 arranged on the inner wall of the first accommodating cavity 100, the first elastic portion 120 and the annular protruding rib 124 are arranged in the fixing groove 106.

[0069] In the embodiment, the second elastic member 12 comprises a first elastic part 120, a second elastic part 122 and an annular protrusion 124. The first elastic part 120 is provided with a first through hole 1260, and the second elastic part 122 is arranged in the first through hole 1260, so that the first elastic part 120 and the second elastic part 122 can be connected by the annular protrusion 124. The second through hole 1262 is arranged on the second elastic part 122. The first elastic member 10 comprises a fixing groove 106. The fixing groove 106 is arranged on the inner wall of the first accommodating cavity 100, and the first elastic part 120 and the annular protrusion 124 are arranged in the fixing groove 106. By arranging the second elastic part 122 and the annular protrusion 124 and arranging them in the fixing groove 106 of the first accommodating cavity 100, the second elastic member 12 can be arranged more stably, especially when the foot pad assembly 1 is deformed under stress, the second elastic member 12 can be more stable, and the stability of the combination of the first elastic member 10 and the second elastic member 12 can be ensured.

[0070] The specific shape of the first elastic part 120 can be arranged according to actual needs.

[0071] In some embodiments, the annular protrusion 124 is connected to the outer periphery of the second elastic part 122 and is arranged close to one end of the second elastic part 122.

[0072] In the embodiment, the annular protrusion 124 is connected to the outer periphery of the second elastic part 122 and is arranged close to one end of the second elastic part 122, that is, the first elastic part 120 is arranged close to one end of the second elastic part 122.

[0073] In some embodiments, the second elastic member 12 can optionally extend out of or not extend out of the first accommodating cavity 100.

[0074] In the embodiment, the second elastic member 12 extends out of or not out of the first accommodating cavity 100. That is, the length of the second elastic member 12 can be arranged according to actual conditions to ensure the strength of the second elastic member 12.

[0075] In some embodiments, the second elastic member 12 can optionally extend out of the first accommodating cavity 100, and the support part 102 is arranged on the part of the second elastic member 12 extending out of the first accommodating cavity 100.

[0076] In the embodiment, the second elastic member 12 extends out of the first accommodating cavity 100. In this way, the support part 102 can be arranged on the part of the second elastic member 12 extending out of the first accommodating cavity 100, so that the vibration generated by the compressor is first transmitted to the second elastic member 12, and then the first elastic member 10 is vibrated by the second elastic member 12. In this way, the second elastic member 12 and the first elastic member 10 can produce slight friction when vibrating, so as to realize the reduction of vibration energy.

[0077] According to one embodiment of the first aspect of the application, a foot pad assembly 1 is proposed and described by taking the foot pad assembly 1 used in a refrigerator as an example. The refrigerator comprises a compressor 2 and a bottom plate provided with threaded holes for fixing screws 142. The foot pad assembly 1 comprises a rubber pad (first elastic member 10), a silicone rubber (second elastic member 12), a bushing (fixing sleeve 140), and a fixing screw 142. The rubber pad contains solidified silicone rubber in the internal cavity, and the silicone rubber can have very small friction with the inner wall of the cavity of the rubber pad. The bushing is arranged in the through hole of the rubber pad and is limited by the shrinkage hole between the rubber pads. The fixing screw 142 is used to lock the metal bushing on the bottom plate 3 of the refrigerator. The compressor 2 is the vibration source, which is pressed on the four foot pad assemblies 1, and is positioned on the bottom plate by the fixing screw 142.

[0078] The foot pad assembly 1 is a rubber pad combined with two materials. In this embodiment, the external material is butyl rubber, and the internal material in the cavity is silicone rubber, which is softer than butyl rubber. In this embodiment, the silicone rubber in the cavity can be replaced by other materials that are softer than the external material.

[0079] The internal cavity of the rubber pad is a closed area surrounded by the inner surface of the rubber pad and the outer surface of the metal bushing. By injecting liquid silicone rubber into the cavity, when the silicone rubber in the cavity solidifies, it fills the entire closed area, forming a supporting structure in the original rubber pad.

[0080] The supporting structure is formed by solidifying liquid silicone rubber, and its shape completely matches the internal cavity of the rubber pad. However, since there is no adhesion between the two, when the external rubber pad deforms due to vibration, the internal silicone rubber deforms later than the external rubber, causing a small displacement at the junction between the two, dissipating the energy of the vibration and achieving the technical effect of vibration reduction and noise reduction.

[0081] The supporting structure is formed by solidifying liquid silicone rubber, and its hardness is less than that of the external butyl rubber. As shown in FIG. 7, when the butyl rubber pad is not filled with a silicone rubber support, the support stiffness is mainly completed by the thin wall of its side. According to experience and the situation of long-distance transportation and long-term operation of the refrigerator system, the rubber pad is prone to crushing deformation, and the empty structure may be at risk of crushing. After filling the silicone rubber support in the internal cavity, the axial support stiffness is significantly improved, so its resistance to fatigue deformation failure is stronger than that of the original hollow rubber pad.

[0082] The key points of the application are described in detail as follows:

[0083] The application aims to solve the deformation and crushing problems of the soft foot pad during long-term operation of the refrigerator, and provides a foot pad assembly 1 suitable for a compressor 2 of a refrigerator. The foot pad assembly 1 has simple structure, the same installation method as the ordinary foot pad, and better vibration reduction and noise reduction capacity and deformation resistance than the ordinary rubber pad. The foot pad assembly 1 of the application is based on the structure of the ordinary foot pad, and is subjected to glue injection treatment. The cavity formed between the inner wall of the rubber pad (first elastic member 10) and the metal bushing (fixed sleeve 140) is filled with silicone material which is softer in material. The silicone material is in liquid state when it is not solidified in the cavity of the foot pad, and is soft silicone rubber after solidification, which can maintain the original softness of the rubber pad. Since the internal cavity of the rubber pad is filled with silicone rubber, the overall deformation resistance of the rubber pad is improved, so the rubber pad after glue injection is not easy to be crushed. In addition, there is a small gap between the inner wall of the rubber pad cavity and the silicone rubber in the cavity. The vibration energy generated during the operation of the compressor 2 can be dissipated through the small relative movement between the two, and the ordinary single material foot pad cannot achieve this energy dissipation effect.

[0084] The second aspect of the application provides a compressor 2, which comprises the foot pad assembly 1 according to any one of the first aspect.

[0085] According to the compressor 2 provided by the application, the foot pad assembly 1 according to any one of the first aspect is included. Since the compressor 2 includes the foot pad assembly 1 according to any one of the first aspect, the compressor 2 provided by the application also has all the beneficial technical effects of the foot pad assembly 1 according to any one of the first aspect, which will not be repeated here.

[0086] In some embodiments, the compressor 2 optionally comprises a reciprocating compressor.

[0087] In some embodiments, the reciprocating compressor optionally comprises a high-speed reciprocating compressor.

[0088] The vibration reduction and noise reduction principle of the compressor 2 will be described in detail below:

[0089] The compressor 2 is a core component of the refrigerator system, and is generally mounted on the bottom plate of the refrigerator system through a rubber pad at the bottom. Specifically, the bottom foot of the compressor 2 is welded to the shell, and the bottom foot is supported on the rubber pad, and the two are only in contact and are not locked. The rubber pad generally has a through hole in the middle, and a small step hole is formed in the through hole, and the step hole is used to fix the bushing of the compressor 2. The upper end of the bushing is in contact with a screw, and the screw fixes the bushing on the bottom plate of the refrigerator system. The locked bushing plays a positioning role on the rubber pad, thereby ensuring that the compressor 2 maintains the correct position in the compressor 2 cabin of the refrigerator system. Since the compressor 2 will vibrate when working, the vibration will be transmitted to the bottom plate of the refrigerator system through the rubber pad, thereby causing the refrigerator system to vibrate and produce low-frequency noise, and the system structure will also be damaged due to long-term vibration.

[0090] Due to the mounting structure between the rubber pad and the bushing of the compressor 2, the metal parts and the metal parts do not directly contact each other. The vibration of the compressor 2 is transmitted to the metal bottom plate after being attenuated by the rubber material. The width of the step hole in the through hole of the rubber pad determines the contact area between the rubber material and the metal material. In the current scheme, if the axial stiffness of the rubber pad is low, the ability of the rubber pad to suppress the low-frequency noise of the refrigerator system is strong. However, since the mass of the compressor 2 is completely supported by the rubber pad, the rubber pad that is too soft will deform or even be crushed during the long-term operation of the refrigerator, thereby reducing the vibration and noise reduction effect.

[0091] The third aspect of the present application provides a refrigeration equipment, comprising: the foot pad assembly 1 in any one of the embodiments of the first aspect; and / or the compressor 2 in the embodiment of the second aspect.

[0092] According to the refrigeration equipment provided by the present application, it comprises the foot pad assembly 1 in any one of the embodiments of the first aspect; and / or the compressor 2 in the embodiment of the second aspect. Therefore, the refrigeration equipment provided by the present application also has all the beneficial technical effects of the foot pad assembly 1 in any one of the embodiments of the first aspect and / or the compressor 2 in the embodiment of the second aspect, which will not be repeated here.

[0093] In some embodiments, the refrigeration equipment can include a refrigerator, a freezer, or the like.

[0094] In the present application, the term "a plurality of" refers to two or more, unless otherwise explicitly limited. The terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, "connecting" can be fixed connection, or detachable connection, or integrally connected; "connected" can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0095] In the description of the application, the terms "one embodiment", "some embodiments”, "certain embodiments”, etc. do not necessarily refer to the same embodiment or example, but instead can refer to one or more or a different embodiment or example. Moreover, descriptive

[0096] The embodiments of the application described hereinabove are intended to be merely exemplary and those skilled in the art will be able to make numerous variations and modifications without departing from the spirit of the present application. All such variations and modifications are intended to be within the scope of the present application.
