DETAILED DESCRIPTION

[0069] The technical solutions of the present application are further described in detail below in combination with the drawings and specific embodiments of the present application.

[0070] In the description of the embodiments of the present application, it should be noted that, unless otherwise stated and limited, the term "connection" should be understood broadly, for example, it can be an electrical connection, or a connection between two elements, it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above-mentioned term can be understood according to the specific circumstances.

[0071] ​​​It should be noted that the terms "first", "second", "third" involved in the embodiments of the present application are only to distinguish similar objects, and do not represent a specific order of the objects. Understandably, "first", "second", "third" can be interchanged in a specific order or sequence as allowed. It should be understood that the objects distinguished by "first", "second", "third" can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0072] The following will be described in detail Figures 1 to 7 The magnetic connection device described in the embodiments of the present application will be described in detail.

[0073] The magnetic connection device described in the embodiments of the present application comprises a main body assembly 100, a knob assembly 200, a lifting assembly 300 and a magnetic assembly 400. The main body assembly 100 has a first matching end face 113; the knob assembly 200 is rotatably arranged on the main body assembly 100; the lifting assembly 300 is arranged on the main body assembly 100 in an axial translational manner and is connected with the knob assembly 200 in a matching manner; the lifting assembly 300 has a second matching end face 330 located on the side of the first matching end face 113; the magnetic assembly 400 is arranged on the first matching end face 113 and / or the second matching end face 330; the magnetic assembly 400 is used to connect with a carrier through magnetic attraction; in the case that the knob assembly 200 rotates relative to the main body assembly 100, the lifting assembly 300 moves in an axial translational manner relative to the main body assembly 100 to adjust the relative distance between the magnetic assembly 400 and the carrier, and further adjust the magnetic attraction between the magnetic assembly 400 and the carrier.

[0074] In the related art, when a mobile phone support is connected with a mobile phone through magnetic attraction, if the magnetic attraction between the mobile phone support and the mobile phone is small, the mobile phone support often separates from the mobile phone and cannot stably support the mobile phone; if the magnetic attraction between the mobile phone support and the mobile phone is large, it is difficult for a user to separate the mobile phone support from the mobile phone, resulting in poor user experience of the mobile phone support. However, in the case that the knob assembly 200 rotates relative to the main body assembly 100, the lifting assembly 300 moves in an axial translational manner relative to the main body assembly 100 to adjust the relative distance between the magnetic assembly 400 and the carrier, and further adjust the size of the magnetic attraction between the magnetic assembly 400 and the carrier. Here, in the case that it is necessary to stably connect the magnetic connection device with the carrier, the relative distance between the magnetic assembly 400 and the carrier can be reduced through the knob assembly 200 to increase the magnetic attraction between the magnetic assembly 400 and the carrier; in the case that it is necessary to separate the magnetic connection device from the carrier, the relative distance between the magnetic assembly 400 and the carrier can be increased through the knob assembly 200 to reduce the magnetic attraction between the magnetic assembly 400 and the carrier, thereby greatly improving the user experience of the magnetic connection device of the present application.

[0075] In the embodiments of the present application, the structure of the main body assembly 100 is not limited. For example, as shown in Figure 1 and Figure 7 , the main body assembly 100 can include a main body piece 110 and a connecting piece 120. The main body piece 110 can include a seat portion 111 and at least one column portion 112. The seat portion 111 has a first mating end face 113; the at least one column portion 112 is protruded from an end of the seat portion 111 opposite to the first mating end face 113; and the connecting piece 120 is connected with the column portion 112 and is spaced apart from the seat portion 111, so as to rotatably clamp at least part of the knob assembly 200 between the seat portion 111 and the connecting piece 120.

[0076] Here, the structure of the seat portion 111 is not limited. For example, the seat portion 111 can have a ring structure. The number of the column portions 112 is not limited. For example, as shown in Figure 7 , the number of the column portions 112 is three.

[0077] Here, the connecting piece 120 can be directly placed on the support body, the connecting piece 120 can also be used to directly and separably connect with the support body, or the connecting piece 120 can be used to detachably connect with the seat body assembly; here, the seat body assembly can be separably connected with the support body or the seat body assembly can be directly placed on the support body. The connecting piece 120 and the seat body assembly can be detachably connected through a snap structure or a threaded structure. The seat body assembly can be separably connected with the support body through clamping, bonding or magnetic attraction.

[0078] The support body refers to an object that supports the magnetic connection device. For example, the support body can be a plate body of a vehicle. For another example, the support body can be a table body. As an example, the support body is a vehicle, and the seat body assembly can be directly fixed on the vehicle through double-sided adhesive tape or fixed on the vehicle through clamping at the air outlet of the air conditioner.

[0079] As an example, an end of the connecting piece 120 away from the main body piece 110 is used to detachably connect with the support body.

[0080] In an application, as shown in Figure 1 and Figure 2 , an end of the connecting piece 120 away from the main body piece 110 is axially protruded with a clamping portion 121, the clamping portion 121 is provided with a spherical clamping space 1211 and an adjusting gap 1212 in communication with the clamping space; the outer side of the clamping portion 121 has a threaded mating portion 1213; the spherical clamping space 1211 is used to mate with the ball head of the seat body assembly; the threaded mating portion 1213 is used to mate with a cylindrical adjusting piece to adjust the size of the spherical clamping space 1211; during use, the ball head of the seat body assembly can be clamped in the spherical clamping space 1211, and then the adjusting piece is adjusted to clamp the ball head of the seat body assembly in the spherical clamping space 1211.

[0081] The first mating end face 113 of the main body assembly 100 is used to mate with the carrier, and here, the first mating end face 113 of the main body assembly 100 can be in direct contact with the carrier, or can be in contact with the carrier through other structural members.

[0082] The carrier refers to an object carried by the magnetic connection device. For example, the carrier can be an electronic device. For another example, the carrier can be a decorative piece.

[0083] Here, the structure of the electronic device is not limited. For example, the electronic device can be a mobile phone, a tablet, or a navigator.

[0084] In the embodiments of the present application, the manner in which the knob assembly 200 is rotatably arranged on the main body assembly 100 is not limited. For example, the knob assembly 200 can include a knob member 210, which can be a cylindrical structure, and the knob member 210 can be rotatably arranged outside a portion of the main body assembly 100.

[0085] As an example, at least a portion of the knob member 210 of the knob assembly 200 is rotatably clamped between the seat portion 111 and the connecting member 120, and here, the column portion 112 passes through the knob member 210.

[0086] In the embodiments of the present application, the lifting assembly 300 has a second mating end face 330 located on the side of the first mating end face 113, so that the lifting assembly 300 mates with the carrier through the second mating end face 330, and here, the lifting assembly 300 can be in direct contact with the carrier through the second mating end face 330, or can be in contact with the carrier through other structural members.

[0087] The manner in which the lifting assembly 300 is connected to the knob assembly 200 is not limited, as long as the lifting assembly 300 moves along the axis relative to the main body assembly 100 when the knob assembly 200 rotates relative to the main body assembly 100.

[0088] For example, the knob assembly 200 and the lifting assembly 300 can be in contact through the convex-concave structure 600, which includes a first convex-concave portion 610 arranged in the circumferential direction and a first concave-convex portion 620 in contact with the first convex-concave portion 610; one of the first convex-concave portion 610 and the first concave-convex portion 620 is arranged on the knob assembly 200, and the other of the first convex-concave portion 610 and the first concave-convex portion 620 is arranged on the lifting assembly 300; the convex portion of the first convex-concave portion 610 can be located in the concave portion of the first concave-convex portion 620; when the knob assembly 200 rotates, the convex portion of the first convex-concave portion 610 can slide out of the concave portion of the first concave-convex portion 620 to be in contact with the convex portion of the first concave-convex portion 620, thereby causing the lifting assembly 300 to move along the axis.

[0089] For another example, the knob assembly 200 and the lifting assembly 300 can be connected by the screw structure 700, which includes a screw groove 710 arranged along the axial direction and a screw protrusion 720 inserted into the screw groove 710; one of the screw groove 710 and the screw protrusion 720 is arranged on the knob assembly 200, and the other of the screw groove 710 and the screw protrusion 720 is arranged on the lifting assembly 300; when the knob assembly 200 rotates, the screw protrusion 720 moves along the screw groove 710, so that the lifting assembly 300 moves along the axial direction.

[0090] Of course, the knob assembly 200 and the lifting assembly 300 can be connected by both the convex-concave structure 600 and the screw structure 700.

[0091] The manner in which the lifting assembly 300 is movably arranged along the axial direction of the main body assembly 100 is not limited. The lifting assembly 300 can be movably arranged along the axial direction of the main body assembly 100 by a guide rail structure or a guide groove structure.

[0092] For example, the main body assembly 100 includes a main body piece 110 and a connecting piece 120. The main body piece 110 includes a seat portion 111 and at least one column portion 112. As shown, the connecting piece 120 is provided with at least one first guide groove 122 along the axial direction. Figure 7 The connecting piece 120 is provided with at least one first guide groove 122 along the axial direction. The lifting assembly 300 includes a first lifting piece 310 and a guide piece 340. The first lifting piece 310 has a first sub-cooperating end face 311 on the side of the first cooperating end face 113; the knob piece 210 is connected with the first lifting piece 310; the guide piece 340 is connected with the first lifting piece 310 on the side opposite to the first sub-cooperating end face 311; the end of the guide piece 340 away from the first lifting piece 310 has at least one guide portion 341 movably arranged along the axial direction in the first guide groove 122. Thus, the first lifting piece 310 is movably arranged along the axial direction in the main body assembly 100 by movably arranging the guide portion 341 along the axial direction in the first guide groove 122.

[0093] In the present example, the knob 210 is connected to the first lifting member 310 in a similar way as the knob 200 is connected to the lifting member 300, which will not be described again. As an example, the knob 210 and the first lifting member 310 can be connected by the convex-concave structure 600. As another example, the knob 210 and the first lifting member 310 can be connected by the screw structure 700. In an application, the knob 210 and the first lifting member 310 are connected by the screw structure 700; the screw structure 700 comprises a screw groove 710 arranged along the axial direction and a screw convex 720 inserted into the screw groove 710; one of the screw groove 710 and the screw convex 720 is arranged on the inner wall of the cavity of the knob 210, and the other of the screw groove 710 and the screw convex 720 is arranged on the outer side of the first lifting member 310; in an example, as shown in Figure 2 and Figure 5 the screw groove 710 is arranged on the outer side of the first lifting member 310, and the screw convex 720 is arranged on the inner wall of the cavity of the knob 210.

[0094] In the present example, the first lifting member 310 and the guide 340 can be connected by adhesion, clamping, welding or the like.

[0095] In the present example, the structure of the first lifting member 310 is not limited. For example, the first lifting member 310 can be a columnar structure or a cylindrical structure.

[0096] In the present example, the structure of the guide 340 is not limited. For example, the guide 340 can be a plate structure or a ring structure.

[0097] In the present example, the structure of the guide part 341 is not limited. The guide part 341 can be a strip structure or a columnar structure. The guide part 341 and the guide 340 can be different parts of one structure or can be connected by adhesion, welding or the like.

[0099] In the present example, as shown in Figure 7As shown, the knob member 210 can be a cylindrical structure, and a portion of the first lifting member 310 can be movably inserted into a cavity of the knob member 210; the first lifting member 310 is a cylindrical structure; the lifting assembly 300 can further include a second lifting member 320 movably inserted into the cavity of the first lifting member 310 along an axial direction and having a second sub-cooperating end surface 321 located at a side of the first cooperating end surface 113; so that the first lifting member 310 and the second lifting member 320 can simultaneously move along the axial direction.

[0100] Here, the structure of the second lifting member 320 is not limited. For example, the second lifting member 320 can be a strip-shaped structure. As an example, the second lifting member 320 can be a columnar structure. The second lifting member 320 can be movably inserted into the cavity of the first lifting member 310 along the axial direction through a guide rail structure or a guide groove structure.

[0101] Here, the second lifting member 320 can be directly connected with the knob member 210 in cooperation, or can be connected with the knob member 210 in cooperation through other structural members. The connection manner of the knob member 210 and the second lifting member 320 in cooperation is similar to the connection manner of the knob assembly 200 and the lifting assembly 300 in cooperation, which will not be repeated here. As an example, the knob member 210 and the second lifting member 320 can be connected in cooperation through the convex-concave structure 600. As another example, the knob member 210 and the second lifting member 320 can be connected in cooperation through the screw structure 700.

[0102] Here, the directions of the first lifting member 310 and the second lifting member 320 moving along the axial direction can be the same or opposite.

[0103] As an example, the knob assembly 200 can further include a cooperating member 220 fixed in the cavity of the knob member 210 and arranged axially adjacent to the second lifting member 320; the cooperating member 220 has a cooperating part 221 corresponding to the cavity of the first lifting member 310, and the cooperating part 221 is connected with the second lifting member 320 in cooperation.

[0104] Here, the cooperating member 220 is located at an end of the second lifting member 320 opposite to the second sub-cooperating end surface 321.

[0105] Here, the way in which the fitting part 221 is fitted and connected with the second lifting part 320 is similar to the way in which the knob assembly 200 and the lifting assembly 300 are fitted and connected, and thus will not be described again. In an application, the fitting part 221 is fitted and contacted with the second lifting part 320 through the convex-concave structure 600; the convex-concave structure 600 includes a first convex-concave part 610 arranged in a circumferential direction and a first concave-convex part 620 fitted and contacted with the first convex-concave part 610; one of the first convex-concave part 610 and the first concave-convex part 620 is arranged at an end surface of the fitting part 221, and the other of the first convex-concave part 610 and the first concave-convex part 620 is arranged at an end surface of the second lifting part 320. In an example, as shown in FIGS. 6 and 7, the first convex-concave part 610 can be arranged at the end surface of the second lifting part 320, and the first concave-convex part 620 is arranged at the end surface of the fitting part 221. Figure 2 and Figure 5 In another example, as shown in FIGS. 8 and 9, the first convex-concave part 610 can be arranged at the end surface of the fitting part 221, and the first concave-convex part 620 is arranged at the end surface of the second lifting part 320.

[0106] When the lifting assembly 300 includes the guide part 340, the guide part 340 can be sleeved outside the fitting part 221 and located between the fitting part 220 and the first lifting part 310 in the axial direction; the fitting part 220 can be provided with a second guide groove 222 through which the guide part 341 passes, as shown in FIG. 10. Figure 7

[0107] Here, when the knob part 210 rotates relative to the main body assembly 100, the first lifting part 310 and the second lifting part 320 can move in opposite directions along the axial direction. Of course, when the knob part 210 rotates relative to the main body assembly 100, the first lifting part 310 and the second lifting part 320 can also move in the same direction along the axial direction.

[0108] In the embodiments of the present application, the structure of the magnetic assembly 400 is not limited. For example, the magnetic assembly 400 can be arranged only at the first fitting end surface 113, or arranged only at the second fitting end surface 330. Of course, the magnetic assembly 400 can also be arranged at the first fitting end surface 113 and the second fitting end surface 330. When the knob assembly 200 rotates relative to the main body assembly 100, the lifting assembly 300 moves relative to the main body assembly 100 along the axial direction, which can change the distance between the first fitting end surface 113 and the second fitting end surface 330 relative to the carrier, so as to adjust the relative distance between the magnetic assembly 400 and the carrier, and further adjust the magnetic attraction force between the magnetic assembly 400 and the carrier.

[0109] ​For example, the magnetic assembly 400 can be arranged only at the first mating end surface 113, and the magnetic assembly 400 and the carrier can have a larger magnetic attraction force when the lifting assembly 300 abuts against the carrier, so that the support stability of the magnetic connecting device is improved. When the magnetic connecting device needs to be connected with the carrier, the lifting assembly 300 can be retracted into the main body assembly 100 without affecting the distance between the magnetic assembly 400 and the carrier, so that the magnetic assembly 400 and the carrier have a larger magnetic attraction force, thereby improving the support stability of the magnetic connecting device.

[0110] For example, the magnetic assembly 400 can be arranged only at the second mating end surface 330, and the magnetic assembly 400 and the carrier can have a larger magnetic attraction force when the lifting assembly 300 abuts against the carrier, so that the support stability of the magnetic connecting device is improved. When the magnetic connecting device needs to be connected with the carrier, the lifting assembly 300 can be retracted into the main body assembly 100 to reduce the magnetic attraction force between the magnetic assembly 400 and the carrier, so that the magnetic connecting device and the carrier are easily separated.

[0111] In some optional implementations of the embodiments of the present application, the knob 210 can be a cylindrical structure, and the lifting assembly 300 can include a first lifting member 310 and a second lifting member 320. The first lifting member 310 can be arranged in the cavity of the knob 210 and connected with the knob 210. The first lifting member 310 is a cylindrical structure. The second lifting member 320 is arranged in the cavity of the first lifting member 310 and connected with the knob 210. When the knob 210 rotates relative to the main body assembly 100, the first lifting member 310 and the second lifting member 320 move in opposite directions along the axial direction, so as to quickly adjust the magnetic force between the magnetic assembly 400 and the carrier.

[0112] The first lifting member 310 and the second lifting member 320 have been described above, and will not be described here again.

[0113] In the implementation, the second mating end surface 330 can include a first sub-mating end surface 311 of the first lifting member 310 and a second sub-mating end surface 321 of the second lifting member 320. The magnetic assembly 400 can include a first magnetic member 410 and a second magnetic member 420. The first magnetic member 410 is arranged at the first sub-mating end surface 311. The second magnetic member 420 is arranged at the first mating end surface 113, so as to improve the magnetic attraction force between the magnetic connecting device and the carrier through the two magnetic members.

[0114] In the present implementation, the lifting assembly 300 is movable to a first state and a second state relative to the main body assembly 100 through the knob 210; in the first state, the first sub-cooperating end face 311 is flush with the first cooperating end face, as shown in Figure 1 、 Figure 2 and Figure 3 , here, the first sub-cooperating end face 311 and the first cooperating end face are substantially the same distance from the carrier, so that the magnetic attraction between the magnetic assembly 400 and the carrier is greater. Here, the second sub-cooperating end face 321 can be flush with the first cooperating end face, or can have a small distance in the axial direction from the first cooperating end face. In the second state, as shown in Figure 4 、 Figure 5 and Figure 6 , by abutting the second sub-cooperating end face 321 against the carrier surface, the distance between the second sub-cooperating end face 321 and the first cooperating end face 113 and the carrier can be increased, thereby reducing the magnetic attraction between the first magnetic member 410 and the second magnetic member 420 and the carrier; by recessing the first sub-cooperating end face 311 inside the main body assembly 100, the magnetic attraction between the first magnetic member 410 and the carrier can be further reduced, so that the cooperation of the first lifting member 310 and the second lifting member 320 can quickly adjust the size of the magnetic force between the magnetic assembly 400 and the carrier.

[0115] In the present implementation, the first lifting member 310 can be provided with a first accommodating groove 312 on the side of the first sub-cooperating end face 311; the first magnetic member 410 can be located in the first accommodating groove 312; the main body assembly 100 can be provided with a second accommodating groove 114 on the side of the first cooperating end face 113, and the second magnetic member 420 can be located in the second accommodating groove 114; to prevent the first magnetic member 410 and the second magnetic member 420 from falling or being damaged.

[0116] In the present implementation, the magnetic connection device can further include a first fitting member 510 and a second fitting member 520. The first fitting member 510 is arranged on the first cooperating end face 113 and covers the second magnetic member 420; the second fitting member 520 is arranged on the first sub-cooperating end face 311 and covers the first magnetic member 410; the second fitting member 520 is provided with a first through hole 521 for the second lifting member 320 to pass through.

[0117] The first fitting member 510 and the second fitting member 520 can prevent the first magnetic member 410 and the second magnetic member 420 from falling or being damaged.

[0118] Here, the material of the first and second fitting members 510 and 520 is not limited. For example, the first fitting member 510 can have a smaller hardness than the second magnetic member 420, and the second fitting member 520 can have a smaller hardness than the first magnetic member 410, so that the carrier can be prevented from being scratched by the first and second fitting members 510 and 520 in contact with the carrier.

[0119] Of course, in other examples, the lifting assembly 300 can also include only one of the first and second lifting members 310 and 320. The magnetic assembly 400 can also include only one of the first and second magnetic members 410 and 420.

[0120] In some optional implementations of the embodiments of the present application, the magnetic connecting device can further include a limiting structure for limiting the limit position of the knob assembly 200 relative to the main body assembly 100, so that the lifting assembly 300 can be switched between the first and second states relative to the main body assembly 100 through the knob assembly 200.

[0121] In the present implementation, the limiting structure is not limited. For example, when the knob assembly 200 and the lifting assembly 300 are connected through the screw structure 700, the limiting structure can be the ends of the two ends of the screw groove 710; when the screw protrusion 720 abuts against the ends of the screw groove 710, the knob assembly 200 is rotated to the limit position relative to the main body assembly 100.

[0122] As an example, as shown in Figure 7 The main body assembly 100 can include a main body member 110 and a connecting member 120. At least part of the knob member 210 of the knob assembly 200 is rotatably clamped between the seat portion 111 and the connecting member 120, and the limiting structure includes at least one limiting through slot 211 formed in the circumferential direction of the knob member 210, and the at least one column portion 112 corresponds to pass through the at least one limiting through slot 211; when the column portion 112 contacts the two ends of the limiting through slot 211, the knob assembly 200 is rotated to the limit position relative to the main body assembly 100.

[0123] Here, the knob member 210 can be rotated within a first angle range relative to the main body member 110 through the at least one column portion 112 corresponding to pass through the at least one limiting through slot 211, and the first angle range is not limited. For example, the first angle range can be 0 degrees to 90 degrees; here, the limiting through slot 211 is arranged in a range of 90 degrees in the circumferential direction. Of course, the first angle range can also be 0 degrees to 60 degrees; here, the limiting through slot 211 is arranged in a range of 60 degrees in the circumferential direction.

[0124] Here, the number of limiting through slots 211 is not limited. As an example, the main body 110 includes three column portions 112 spaced apart in the circumferential direction, and correspondingly, the knob 210 has three limiting through slots 211 in the circumferential direction.

[0125] This application also describes an electronic device bracket, including a base assembly and a magnetic connection device according to this application embodiment; the base assembly is used to contact a support body, and the support body is an electronic device;

[0126] The base assembly is connected to the main body assembly 100.

[0127] In this embodiment, the magnetic component 400 is used to connect with an electronic device via magnetic attraction. When the knob component 200 rotates relative to the main component 100, the lifting component 300 translates axially relative to the main component 100 to adjust the relative distance between the magnetic component 400 and the electronic device, thereby adjusting the magnitude of the magnetic attraction between the magnetic component 400 and the electronic device. Here, when it is necessary to stably connect the magnetic connection device with the electronic device, the relative distance between the magnetic component 400 and the electronic device can be decreased by the knob component 200 to increase the magnetic attraction between the magnetic component 400 and the electronic device. When it is necessary to separate the magnetic connection device from the electronic device, the relative distance between the magnetic component 400 and the electronic device can be increased by the knob component 200 to decrease the magnetic attraction between the magnetic component 400 and the electronic device, thereby greatly improving the user experience of the electronic device holder of this application.

[0128] In this embodiment, the connection method between the base assembly and the main body assembly 100 is not limited. For example, the base assembly and the main body assembly 100 can be fixedly connected by a threaded structure, a welded structure, or the like. Alternatively, the main body assembly 100 can be detachably connected to the base assembly. As an example, the main body assembly 100 and the base assembly can be detachably connected by a snap-fit ​​structure or a threaded structure.

[0129] When the main body assembly includes the connector 120, the connector 120 and the base assembly can be detachably connected via a snap-fit ​​structure or a threaded structure.

[0130] In one application, the base assembly includes a ball joint, and the electronic device bracket may also include an adjustment element. For example... Figure 1 and Figure 2As shown, the end of the connector 120 away from the main body 110 has a clamping part 121 protruding axially. The clamping part 121 has a spherical clamping space 1211 and an adjustment notch 1212 communicating with the clamping space. The outer side of the clamping part 121 has a threaded engagement part 1213. The spherical clamping space 1211 engages with the ball head of the seat assembly. The threaded engagement part 1213 engages with a cylindrical adjustment part to adjust the size of the spherical clamping space 1211. During use, the ball head of the seat assembly can be clamped in the spherical clamping space 1211, and then the adjustment part can be adjusted to make the spherical clamping space 1211 clamp the ball head of the seat assembly.

[0131] In this embodiment, the base assembly and the support can be detachably connected. Of course, the base assembly can also be placed directly on the support.

[0132] The above embodiments have already described the support and electronic devices, and will not be repeated here.

[0133] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0134] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
