[0042] The present invention discloses a support structure for easy use.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0044] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, an embodiment of the present utility model provides a support structure, which includes a support member 100, a connection assembly 500 and a control assembly. Among them, the support member 100 has a first surface and a second surface facing away from each other. The first surface is used to connect the first body 200, and the second surface is used to connect the second body 300. In this embodiment, the support member 100 can be a plate-like structure, and its first surface and second surface are respectively two opposite surfaces of the plate-like structure. Moreover, when the first body 200 and the second body 300 are also plate-like structures, the first surface of the support member 100 can form a surface-to-surface contact with one surface of the first body 200, and the second surface of the support member 100 can form a surface-to-surface contact with one surface of the second body 300. The support member 100 can also be adjusted according to the specific structures of the first body 200 and the second body 300 to improve the support stability.

[0045] The connection assembly 500 has a first state and a second state. Among them, in the first state, the first body 200 and / or the second body 300 can be fixedly connected to the support member 100 through the connection assembly 500, and in the second state, the first body 200 and / or the second body 300 can be separated from the support member 100. Among them, when the first body 200 and / or the second body 300 are fixedly connected to the support member 100 through the connection assembly 500, the first body 200 and / or the second body 300 are connected to the support member 100 in space, and the relative positions of the first body 200 and / or the second body 300 and the support member 100 will not change, so that the first body 200 and / or the second body 300 can move and be placed as a whole assembly with the support member 100. When the first body 200 and / or the second body 300 can be separated from the support member 100, the first body 200 and / or the second body 300 can move relative to the support member 100, so as to adjust the positional relationship between the first body 200 and / or the second body 300 and the support member 100, or move and place the first body 200, the second body 300 and the support member 100 separately.

[0046] The control assembly is used to control the connection assembly 500 to switch between the first state and the second state, and the control assembly has a contact portion 410 for contacting the first body 200. Among them, the contact portion 410 can be used as a trigger component for controlling the connection assembly 500 to switch between the first state and the second state.

[0047] Among them,

[0048] When the contact portion 410 is in contact with the first body 200, the control component controls the connection component 500 to be in the first state, and the first body 200 and / or the second body 300 are fixedly connected to the support member 100 through the connection component 500; wherein, the contact between the contact portion 410 and the first body 200 can be a physical contact, that is, through the relative movement of the contact portion 410 and the first body 200, the contact portion 410 is relatively close to the first body 200, so that the contact portion 410 can contact the physical structure on the side of the first body 200 facing the contact portion 410.

[0049] In an embodiment where the connection component 500 is switched between the first state and the second state by electrical control, the contact between the contact portion 410 and the first body 200 can enable the contact portion 410 to be electrically connected to the first body 200, that is, the contact position between the contact portion 410 and the first body 200 can be used as a part of the circuit for controlling the switching of the connection component 500 between the first state and the second state, so that the connection component 500 is switched between the first state and the second state according to whether the contact portion 410 is electrically connected to the first body 200; it can also make the contact between the contact portion 410 and the first body 200 only a physical contact, and the contact between the contact portion 410 and the first body 200 can trigger an electrical control signal, so that the connection component 500 is switched between the first state and the second state through the electrical control signal. Among them, it can be that the pressure received by the contact portion 410 and / or the first body 200 is different depending on whether the contact portion 410 is in contact with the first body 200 (when the contact portion 410 is in contact with the first body 200, the contact portion 410 and / or the first body 200 is under pressure; when the contact portion 410 is separated from the first body 200, the contact portion 410 and / or the first body 200 is not under pressure) as the control condition for triggering the electrical control signal.

[0050] In an embodiment where the connection component 500 switches between the first state and the second state by mechanical control, the contact between the contact portion 410 and the first body 200 can be part of the transmission process. That is, the contact between the contact portion 410 and the first body 200 can be achieved by the relative approaching movement of the contact portion 410 and the first body 200. In the state where the contact portion 410 is in contact with the first body 200, the support structure approaches the first body 200 relatively, which can enable the control component as a physical component to apply a control action to the connection component 500, causing the connection component 500 to switch to the first state; and, the separation between the contact portion 410 and the first body 200 can be achieved by the relative moving away of the contact portion 410 and the first body 200. In the state where the contact portion 410 is separated from the first body 200, the support structure moves away from the first body 200 relatively, which can enable the control component as a physical component to cancel the control action or change the control action on the connection component 500, causing the connection component 500 to switch to the second state.

[0051] The contact portion 410 can touch the component of the first body 200 or

[0052] In the state where the contact portion 410 is separated from the first body 200, the control component controls the connection component 500 to be in the second state, and the first body 200 and / or the second body 300 can be separated from the support 100.

[0053] The separation of the contact portion 410 from the first body 200 means that there is a gap between the contact portion 410 and the first body 200. In an embodiment where the contact between the contact portion 410 and the first body 200 can achieve electrical connection, the gap generated by the separation of the contact portion 410 from the first body 200 is sufficient to cut off the power between the contact portion 410 and the first body 200. In an embodiment where the contact between the contact portion 410 and the first body 200 can cause the contact portion 410 and / or the first body 200 to be under pressure and the pressure is used as the basis for the control component to control the connection component 500 to switch between the first state and the second state, the separation of the contact portion 410 from the first body 200 causes the contact portion 410 and the first body 200 not to be under pressure from each other.

[0054] And, the separation of the contact portion 410 from the first body 200 can be achieved by manually applying an external force to cause local deformation of the first body 200 and separate it from the contact portion 410. After that, the control component controls the connection component 500 to be in the second state, and then controls the first body 200 and / or the second body 300 to be separable from the support 100.

[0055] The support structure provided by the embodiment of the present utility model can realize the switching of the connection component 500 between the first state and the second state through the contact and separation of the contact portion 410 and the first body 200, thereby facilitating the fixed connection and separation of the support member 100 and the first body 200 and / or the second body 300, and further facilitating the use.

[0056] Taking the first body 200 as a circuit board and the second body 300 as a display screen as an example, the battery can be fixedly connected to the second body 300 or the second body 300. When the support member 100 is fixedly connected to the second body 300, the fixed connection between the battery and the second body 300 can be realized. When the support member 100 is separated from the second body 300, the separation between the battery and the second body 300 can be realized. By the contact and separation of the contact portion 410 and the first body 200 to realize the switching of the connection component 500 between the first state and the second state, the operation of tightening and loosening the stud can be avoided, which is convenient for the disassembly and assembly of the circuit board and the display screen, and is convenient for use in scenarios such as development and design.

[0057] For example, in the prior art, when the display screen needs to be installed on the circuit board, the circuit board needs to have a large area, which easily causes an increase in cost. By the support structure provided by the embodiment of the present utility model, the first body 200 (circuit board) and the second body 300 (display screen) are indirectly connected, so that the sizes of the first body 200 and the second body 300 are not limited by each other, and the situation that one of the bodies increases in size due to the need to have an area for installing the other body is avoided.

[0058] As Figure 3 shown, the first body 200 can be a circuit board combined structure formed by fixedly connecting a plurality of circuit boards, that is, a plurality of circuit boards are fixedly connected into an integral circuit board group through connectors such as studs. When the first body 200 is fixedly connected to the support member 100 through the connection component 500, the connection component 500 can enable the support member 100 to be connected to one of the plurality of circuit boards, or can also enable the support member 100 to be connected to at least two circuit boards.

[0059] It can also be such that the first body 200 is a battery and the second body 300 is a display screen. By the contact and separation of the contact portion 410 and the first body 200 to realize the switching of the connection component 500 between the first state and the second state, the relative fixation and separation of the battery and the display screen can be facilitated, which is convenient for use in scenarios such as development and design.

[0060] In this embodiment, the control component includes a control part 420. The control part 420 has opposite third and fourth faces. The contact part 410 is located on the third face, and the fourth face faces the second body 300. Among them, the control part 420 can be a circuit board, which is relatively independent of the first body 200. The third and fourth faces of the control part 420 are respectively two faces of the circuit board.

[0061] Among them, the control part 420 can be connected to the support 100. The control part 420 can be located on the side of the support 100 facing the first body 200, and the control part 420 can be fixedly connected to the first face of the support 100, that is, the fourth face of the control part 420 is fixedly connected to the first face of the support 100. Among them, the control part 420 can be fixedly connected to the first face of the support 100, that is, the fourth face of the control part 420 and the first face of the support 100 form a surface-to-surface connection structure. Of course, a groove structure can also be provided on the first face of the support 100 so that at least part of the control part 420 is embedded in the groove structure. The control part 420 can also be connected to the support 100 through a connecting piece. The connecting piece is located between the control part 420 and the support 100. One end of the connecting piece is fixedly connected to the fourth face of the control part 420, and the other end of the connecting piece is fixedly connected to the first face of the support 100, so that there is a certain distance between the fourth face of the control part 420 and the first face of the support 100.

[0062] Of course, the control part 420 can also be located on the side of the support 100 facing the second body 300. The control part 420 can be fixedly connected to the second face of the support 100. The support 100 has an avoidance space for the contact part 410 to pass through the support 100, so that the contact part 410 can pass through the avoidance space and contact the first body 200. The support 100 can also have an accommodation space for accommodating the control part 420, etc.

[0063] The control part 420 and the support 100 can also be relatively independent components, that is, there is no physical connection relationship between the control part 420 and the support 100.

[0064] The control part 420 has an electrical connection path for connecting to a power supply component. The control part 420 supplies power to the connection component 500 through the power supply component, so that the connection component 500 is in a first state or a second state. Among them, the power supply component can be a component such as a storage battery that can provide electrical energy. As an external component relatively independent of the support structure provided by the embodiments of the present invention, the power supply component can be connected to the control part 420 through the electrical connection path during the use of the support structure, or the power supply component can always be connected to the control part 420 through the electrical connection path.

[0065] In this embodiment, the contact portion 410 may include an electrical connection contact for controlling the on / off of an electrical connection path, or may include a control contact for controlling the current direction in the electrical connection path of the control component 420.

[0066] As Figure 4 and Figure 5 shown, the control component 420 may include a square plate in the figure and a wire 421 electrically connected to the square plate. Among them, the electrical connection path for connecting to the power supply component of the control component 420 may include the wire 421. The wire 421 is part of the power supply from the power supply component to the connection component 500. The square plate may be a circuit board, and the circuit structure thereon also belongs to the electrical connection path.

[0067] The connection component 500 includes a first connection group 510 disposed on the first surface. The first connection group 510 includes a first magnetic attraction component 511 and a second magnetic attraction component 512. The first magnetic attraction component 511 is disposed on the support member 100; the second magnetic attraction component 512 is used to be disposed on the first body 200 and can be correspondingly disposed with the second magnetic attraction component 512;

[0068] Among them, when the contact portion 410 is in contact with the first body 200, the control component 420 supplies power to the second magnetic attraction component 512 and / or the first magnetic attraction component 511 through the power supply component, and the current in the electrical connection path flows in the positive direction, so that there is a first magnetic attraction force between the second magnetic attraction component 512 and the first magnetic attraction component 511, and the first body 200 and the support member 100 can be connected under the action of the first magnetic attraction force.

[0069] At least one of the first magnetic attraction component 511 and the second magnetic attraction component 512 is an electromagnet. That is, both the first magnetic attraction component 511 and the second magnetic attraction component 512 may be electromagnets. When the contact portion 410 is in contact with the first body 200, the control component 420 supplies power to the second magnetic attraction component 512 and / or the first magnetic attraction component 511 through the power supply component. When the current in the electrical connection path flows in the positive direction, there is a first magnetic attraction force between the second magnetic attraction component 512 and the first magnetic attraction component 511, which is used as the force to drive the first body 200 towards the support member 100, so that the first body 200 and the support member 100 are fixedly connected. It is also possible that one of the first magnetic attraction component 511 and the second magnetic attraction component 512 is an electromagnet, and the other is a matching component that can generate a first magnetic attraction force with the electromagnet when maintaining the power supply to the electromagnet and the current in the electrical connection path flowing in the positive direction. The matching component may be a magnet or a metal component that can generate a magnetic attraction force with the electromagnet.

[0070] In one embodiment, when the contact portion 410 is separated from the first body 200, the power supply component and the first connection group 510 are in a power-off state, and no current flows in the electrical connection path, so that there is no magnetic attraction force between the second magnetic component 512 and the first magnetic component 511. That is, the contact portion 410 includes electrical connection contacts for controlling the on / off of the electrical connection path. When the contact portion 410 is separated from the first body 200, the electrical connection path is in an open state, so that no current flows in the electrical connection path, and the power supply component cannot supply power to the first connection group 510. Similarly, both the second magnetic component 512 and the first magnetic component 511 can be electromagnets, or one electromagnet and a cooperating component (magnet or metal component) cooperating with the electromagnet.

[0071] In another embodiment, the control component 420 supplies power to the second magnetic component 512 and / or the first magnetic component 511 through the power supply component, and the current in the electrical connection path flows in the reverse direction, so that a repulsive force is generated between the second magnetic component 512 and the first magnetic component 511, and the first body 200 and the support member 100 can be separated. That is, the contact portion 410 includes control contacts for controlling the current direction in the electrical connection path of the control component 420, so that when the contact portion 410 is switched from the contact state to the separated state with the first body 200, the current in the electrical connection path is switched from flowing in the forward direction to flowing in the reverse direction. Similarly, both the second magnetic component 512 and the first magnetic component 511 can be electromagnets, or one electromagnet and a magnet cooperating with the electromagnet.

[0072] The connection assembly 500 includes a second connection group 520 disposed on the second surface. The second connection group 520 includes a first magnetic member 521 and a second magnetic member 522. The first magnetic member 521 is connected to the support member 100; the second magnetic member 522 can be correspondingly disposed with the first magnetic member 521 and form a space for placing the second body 300 between the second magnetic member 522 and the first magnetic member 521;

[0073] Wherein, when the contact portion 410 is in contact with the first body 200, the control component 420 supplies power to the first magnetic member 521 and / or the second magnetic member 522 through the power supply component, and the current in the electrical connection path flows in the forward direction, so that a second magnetic attraction force is generated between the first magnetic member 521 and the second magnetic member 522, and the first magnetic member 521 and the second magnetic member 522 can clamp the second body 300 under the action of the second magnetic attraction force, so that the second body 300 is connected to the support member 100;

[0074] At least one of the first magnetic member 521 and the second magnetic member 522 is an electromagnetic component (such as an electromagnet or an electromagnetic array). That is, both the first magnetic member 521 and the second magnetic member 522 can be electromagnetic components. In a state where the contact portion 410 is in contact with the first body 200, the control component 420 supplies power to the first magnetic member 521 and / or the second magnetic member 522 through the power supply component. When the current in the electrical connection path flows in the forward direction, a second magnetic attraction force exists between the first magnetic member 521 and the second magnetic member 522 to clamp the second body 300, so that the second body 300 is fixedly connected to the support member 100. It is also possible that one of the first magnetic member 521 and the second magnetic member 522 is an electromagnetic component, and the other is a matching component that can generate a first magnetic attraction force with the electromagnetic component when power is supplied to the electromagnetic component and the current in the electrical connection path flows in the forward direction. The matching component can be a magnet or a metal component that can generate a magnetic attraction force with the electromagnetic component.

[0075] In one embodiment, when the contact portion 410 is separated from the first body 200, the power supply component and the second connection group 520 are in a power-off state, and no current flows in the electrical connection path, so that there is no magnetic attraction force between the first magnetic member 521 and the second magnetic member 522. That is, the contact portion 410 includes electrical connection contacts for controlling the on / off of the electrical connection path. When the contact portion 410 is separated from the second body 300, the electrical connection path is in an open state, so that no current flows in the electrical connection path, and the power supply component cannot supply power to the second connection group 520. Similarly, both the first magnetic member 521 and the second magnetic member 522 can be electromagnetic components, or one can be an electromagnetic component and the other can be a matching component (magnet or metal component) that cooperates with the electromagnet.

[0076] In another embodiment, the control component 420 supplies power to the first magnetic member 521 and / or the second magnetic member 522 through the power supply component, and the current in the electrical connection path flows in the reverse direction, so that a repulsive force is generated between the first magnetic member 521 and the second magnetic member 522, enabling the second body 300 to be separated from the support member 100. That is, the contact portion 410 includes control contacts for controlling the direction of the current in the electrical connection path of the control component 420, so that when the contact portion 410 switches from contact with the second body 300 to separation, the current in the electrical connection path switches from flowing in the forward direction to flowing in the reverse direction. Similarly, both the first magnetic member 521 and the second magnetic member 522 can be electromagnetic components, or one can be an electromagnetic component and the other can be a magnet that cooperates with the electromagnet.

[0077] An elastic member can also be added. Under the action of the elastic restoring force of the elastic member, the second magnetic attraction member 512 can be made to move relatively away from the first magnetic attraction member 511. Wherein, the elastic member can be arranged on the support member 100, one end of which abuts against and is connected to the support member 100, and the other end is used to abut against the first body 200. In a state where there is a first magnetic attraction force between the second magnetic attraction member 512 and the first magnetic attraction member 511, the first body 200 and the support member 100 overcome the elastic restoring force to make the second magnetic attraction member 512 and the first magnetic attraction member 511 approach and realize the fixed connection between the first body 200 and the support member 100. In a state where there is no magnetic attraction force between the second magnetic attraction member 512 and the first magnetic attraction member 511, the first body 200 and the support member 100 move relatively away under the action of the elastic restoring force, so that the second magnetic attraction member 512 and the first magnetic attraction member 511 move relatively away.

[0078] Alternatively, under the action of the elastic restoring force of the elastic member, the first magnetic attraction member 521 can be made to move relatively away from the second magnetic attraction member 522. Wherein, the elastic member can be arranged on the support member 100 and between the first magnetic attraction member 521 and the second magnetic attraction member 522. One end of it abuts against the first magnetic attraction member 521, and the other end abuts against the second magnetic attraction member 522. Under the action of the elastic restoring force, the first magnetic attraction member 521 and the second magnetic attraction member 522 move relatively away. In a state where a second magnetic attraction force is generated between the first magnetic attraction member 521 and the second magnetic attraction member 522, the elastic restoring force is overcome to make the first magnetic attraction member 521 and the second magnetic attraction member 522 move relatively closer.

[0079] In this embodiment, the first body 200 is a circuit board, and the second magnetic attraction member 512 and the first magnetic attraction member 511 are preferably electromagnets, which is convenient for arranging the second magnetic attraction member 512 on the first body 200. The second body 300 is a display screen. The second body 300 is fixedly connected to the support member 100 by clamping the first magnetic attraction member 521 and the second magnetic attraction member 522 in the second connection group 520, avoiding arranging electromagnetic components on the second body 300. Wherein, in order to further facilitate the separation of the second body 300 from the support member 100, the first magnetic attraction member 521 and the second magnetic attraction member 522 are electromagnetic arrays and the electrodes in their corresponding regions are opposite.

[0080] Furthermore, for the convenience of setting, one end of the second magnetic attraction member 522 is hinged to the support member 100. In a state where the contact portion 410 contacts the first body 200, the second magnetic attraction member 522 rotates relative to the support member 100 to the first position, the second magnetic attraction member 522 and the first magnetic attraction member 521 are correspondingly arranged, and a second magnetic attraction force is generated between the first magnetic attraction member 521 and the second magnetic attraction member 522, and the second body 300 can be located between the first magnetic attraction member 521 and the second magnetic attraction member 522.

[0081] It is also possible to make the second magnetic member 522 relatively independent of the support member 100. When the contact portion 410 is in contact with the first body 200, the second magnetic member 522 can cooperate with the first magnetic member 521 under the action of the second magnetic attraction force to clamp the second body 300.

[0082] In order to further facilitate the disassembly and assembly of the second body, when the contact portion 410 is separated from the first body 200, the second magnetic member 522 rotates relative to the support member 100 to a second position, so that the second magnetic member 522 is away from the first magnetic member 521. Among them, the force that drives the second magnetic member 522 to rotate relative to the support member 100 to the second position can be the repulsive force generated between the first magnetic member 521 and the second magnetic member 522, or an elastic restoring force provided by a torsion spring arranged at the hinge joint between the second magnetic member 522 and the support member 100. Under the action of the elastic restoring force of the torsion spring, the second magnetic member 522 is driven to rotate relative to the support member 100 to the second position.

[0083] In this embodiment, when the support member 100 is connected to the second body 300, the orthographic projection area of the second body 300 on the support member 100 is the first area, and the first magnetic member 521 is located within the first area; the position where the second magnetic member 522 is hinged to the support member 100 is located in the second area of the support member 100, and the first area and the second area are relatively independent. Through the above settings, it is ensured that the opposite surfaces (the surfaces that can generate the second magnetic attraction force) of the first magnetic member 521 and the second magnetic member 522 are all in contact with the second body 300, improving the stability of the fixed connection of the second body 300.

[0084] It is also possible that only part of the opposite surfaces of the first magnetic member 521 and the second magnetic member 522 are in contact with the second body 300, and the other part is suspended. That is, the first magnetic member 521 may only be partially located within the first area.

[0085] In order to further improve the fixing stability and the connection and separation efficiency between the second body 300 and the support member 100, the number of the second connection groups 520 is multiple and can be circumferentially distributed along the second body 300; the control component 420 is used to synchronously control the electrical connection of the multiple second connection groups 520 to the power supply component.

[0086] It is also possible that the control component 420 is used to sequentially control the electrical connection of the multiple second connection groups 520 to the power supply component, and the sequence of controlling the electrical connection of the multiple second connection groups 520 to the power supply component is determined according to actual needs and will not be specifically limited here.

[0087] Further, in a state where the contact portion 410 is in contact with the first body 200, the control component 420 controls the power supply component to be electrically connected to the first body 200 and / or the second body 300; the first body 200 is a circuit board to be tested; the second body 300 is a display, and the second body 300 has a fifth surface and a sixth surface facing away from each other. The fifth surface is a surface for outputting information, and the sixth surface is for facing the support member 100. Among them, when it is necessary to separate the contact portion 410 from the first body 200, a force that will not cause damage to the first body 200 can be manually applied to the first body 200 or a tool can be used, so that the area where the first body 200 is in contact with the contact portion 410 elastically deforms, so as to realize the separation of the contact portion 410 from the first body 200, and further make the connection assembly 500 in the second state.

[0088] The contact portion 410 may include a plurality of contacts (PIN pins). Among them, there are power supply contacts for supplying power to the first body 200 and / or the second body 300, which are used to provide electrical energy to the first body 200 and / or the second body 300. There may also be ground contacts for grounding the control component 420 and other circuit boards such as the second body 300. It may also include contacts for controlling the on / off or electromagnetic polarity of the first connection group 510 and the second connection group 520, etc., which are used to control the switching of the first connection group 510 and the second connection group 520 between the first state and the second state.

[0089] Among them, the contact of the contacts for controlling the on / off of the first connection group 510 and the second connection group 520 with the first body 200 can conduct an electrical connection path; the contacts for controlling the electromagnetic polarity of the first connection group 510 and the second connection group 520 can control the current direction in the conducted electrical connection path. The specific solutions for the switching of the first connection group 510 and the second connection group 520 between the first state and the second state are as follows:

[0090] When the contacts for controlling the on / off or electromagnetic polarity of the first connection group 510 and the second connection group 520 are in contact with the first body 200, the electrical connection path is conducted, and there is a positive current flowing in the electrical connection path. The control component 420 supplies power to the connection assembly 500 through the power supply component, so that a first magnetic attraction force is generated between the second magnetic attraction component 512 and the first magnetic attraction component 511 in the first connection group 510, and a second magnetic attraction force is generated between the first magnetic attraction member 521 and the second magnetic attraction member 522 in the second connection group 520.

[0091] When the contacts controlling the power on / off of the first connection group 510 and the second connection group 520 are separated from the first body 200, the electrical connection path is opened, no current flows in the electrical connection path, the power supply component and the connection component 500 are in a power-off state, so that there is no magnetic attraction force between the second magnetic component 512 and the first magnetic component 511 in the first connection group 510, and there is no magnetic attraction force between the first magnetic component 521 and the second magnetic component 522 in the second connection group 520.

[0092] When the contacts controlling the electromagnetic polarity of the first connection group 510 and the second connection group 520 are separated from the first body 200, the electrical connection path is conducted, and current flows reversely in the electrical connection path. The control component 420 supplies power to the connection component 500 through the power supply component, so that a first repulsive force is generated between the second magnetic component 512 and the first magnetic component 511 in the first connection group 510, and a second repulsive force is generated between the first magnetic component 521 and the second magnetic component 522 in the second connection group 520.

[0093] To facilitate the setting of the power supply component, the support member 100 has a hollow cavity 110, and the power supply component can be located in the hollow cavity 110.
