When the surface of the moving member provided with the access point of the second circuit presses or abuts against the conductive hook and moves in the horizontal direction, after the front end of the moving member slides over the sliding inclined plane, the hook portion abuts or presses against the moving member. When the conductive contact touches the access point of the second circuit, the conductive hook electrically connects the first circuit and the second circuit at both ends thereof;

[0009] When the moving member moves in the reverse direction, the reverse anti-retreat abutting surface is abutted by a horizontal force, thereby preventing the moving member from continuing to move.

[0010] Preferably, the sliding inclined plane intersects with the reverse anti-retreat abutting surface to form a free end. The highest points of the sliding inclined plane and the reverse anti-retreat abutting surface are both located at the free end, and the outer surface of the free end is a conductive contact surface;

The moving part presses the hook part and moves forward along the sliding inclined plane. When the hook part abuts or contacts the access point of the second circuit, the first circuit electrically connected to the conducting end is electrically connected and conducted with the access point of the second circuit of the moving part. When the moving part moves in the reverse direction, the reverse anti-retreat abutting surface engages with the moving part to prevent the moving part from continuing to move, realizing the unidirectional movement function of the conductive hook. The connecting part is connected to the external connecting component through an elastic connection method. During the process of the moving part pressing the conductive hook and moving in the horizontal direction, it is ensured that the hook part always abuts the moving part, so that the first circuit and the second circuit are stably connected, facilitating the movement of the moving part, and realizing the corresponding positioning and signal transmission sensing functions.

[0038] The realization of the object, functional features and advantages of the present invention will be further described in conjunction with the embodiments with reference to the drawings. Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0041] In addition, the descriptions involving "first", "second", etc. in the present invention are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0042] A circuit is a conductive loop composed of metal wires and electrical and electronic components, called a circuit. When the circuit is connected, current is generated and it can work. The circuit can work by applying an external power source, or it can also work by generating current through RFID radio frequency identification technology. Generally, a circuit is controlled by a switch to work, but for a device with one or multiple disconnected circuits that needs to be connected to one or multiple external circuits to work, it can be achieved through one or more conductive claws of the present invention.

[0043] Please refer to Figure 1 and Figure 2, the conductive hook of the present invention includes a hook body 100. The hook body 100 includes a hook portion 10, a hook arm 20, and a connecting portion 30. The hook portion 10 is located at one end of the hook arm 20, and a conductive contact is provided on its surface. The hook body 100 is also provided with a conduction end 40, which is electrically connected to an access point of the first circuit. The conductive contact and the conduction end 40 are electrically connected through the hook body 100. Part or all of the surface of the hook body 100 is covered with a shaping layer made of plastic material. The connecting portion 30 is located at the other end of the hook arm 20. The connecting portion 30 is connected to an external connecting component through an elastic connection method, and a connecting shaft is constructed at the connection portion; when the sliding inclined surface 11 is subjected to a force, the conductive hook is compressed downward and makes a circumferential movement around the connecting shaft. When the force is removed, the conductive hook can bounce upward and return to the initial position, or move toward the initial position, or reset along the original path;

[0044] When the conductive hook is installed on the external connecting component, the included angle between the sliding inclined surface 11 and its positive projection on the horizontal plane is set to be acute, and the reverse anti-retreat abutting surface 12 coincides with its positive projection on the horizontal plane or the included angle is set to be acute;

[0045] When the sliding inclined surface 11 is subjected to a horizontal force, the conductive hook is compressed downward and makes a circumferential movement around the connecting shaft. When the horizontal force is removed, the conductive hook can bounce upward;

[0046] Among them, a moving member includes a second circuit. An access point of the second circuit is located on the surface of the moving member. During the process that the surface of the moving member provided with the second circuit access point presses or abuts against the conductive hook and moves horizontally, after the front end of the moving member slides over the sliding inclined surface 11, the hook portion 10 abuts or presses against the moving member. When the conductive contact touches the second circuit access point, the conductive hook electrically connects the first circuit and the second circuit at both ends thereof;

[0047] When the moving member moves in the reverse direction, that is, in the direction opposite to the forward direction, the reverse anti-retreat abutting surface 12 is abutted by a horizontal force, thereby preventing the moving member from continuing to move.

[0048] The technical solution of the present invention enables the hook body to have conductivity through the electrical connection between the conductive contact and the conduction end, the elastic connection mode of the connecting part, and the reverse anti-retreat abutting surface 12 provided on the hook part 10. The moving part presses the hook part 10 and moves forward along the sliding inclined surface 11. When the hook part 10 abuts or contacts the second circuit access point to connect the conductive contact with the second circuit access point, the first circuit electrically connected to the hook body 100 is electrically connected and conducted with the second circuit access point of the moving part. When the moving part moves in the reverse direction, the reverse anti-retreat abutting surface 12 engages with the moving part to prevent the moving part from continuing to move, realizing the one-way movement function of the conductive hook. The connecting part 30 is connected to the external connecting component through an elastic connection mode. During the process that the moving part presses the conductive hook and moves in the horizontal direction, it ensures that the hook part 10 always abuts the moving part, enabling the stable connection of the first circuit and the second circuit, facilitating the movement of the moving part, realizing the corresponding positioning and signal transmission sensing functions, and at the same time increasing the movement touch feeling of the hand pushing the moving part, with flexible control and convenient operation.

[0049] Among them, the surface of the hook part 10 is paved with conductive contacts, that is, the conductive contacts can conduct electricity. The surface of the hook part 10 can be entirely paved with conductive contacts, or the upper surface of the hook part 10 can be paved with conductive contacts, or a partial area of the upper surface of the hook part 10 can be provided with conductive contacts. The conductive contacts are used to connect the second circuit. Therefore, the conductive contacts can be formed by plating metal on the surface of the hook part 10, or metal sheets or metal blocks can be embedded in the hook part. The metal is a conductive metal, and the metal includes silver, copper, aluminum, iron, tungsten, and alloys, etc.

[0050] Please refer to Figure 1 and Figure 2 , the conduction end 40 is made of a conductive material, such as metal, etc. The conduction end 40 can be formed by plating metal on the surface of the hook part, or metal sheets or metal blocks can be embedded or protruded on the hook body 100. The metal is a conductive metal. The conduction end 40 has various design structures. One structural design is, please refer to Figure 1 , the conduction end 40 is a protrusion protruding from the connecting part 30. A groove is also provided at the free end of the conduction end 40 to facilitate the connection with the access point of the first circuit. Generally, the wire of the circuit is electrically connected to the conduction end 40 by welding. The groove provided on the conduction end 40 is used for connection and also plays a role in protecting the connection end to prevent damage caused by external contact. The conduction end 40 is provided on the connecting part 30, making the overall structure of the conductive hook beautiful and compact, while enhancing the strength of the connecting part 30, facilitating the elastic movement of the conductive hook, and preventing contact with other structures. Therefore, the conduction end 40 is arranged in the elastic movement direction of the conductive hook;

[0051] Please refer to Figure 3 and Figure 4Another position change design of the conducting end 40 is that the conducting end 40 can protrude from the hook claw arm 20, and the conducting end 40 can be a long, oval, circular or other protrusion; another design method of the conducting end 40 is that the conducting end 40 can also be a groove recessed in the hook claw body 100, and the conducting end 40 is located on the inner wall of the groove; or the conducting end 40 is laid on the surface of the hook claw body 10, and the area occupied by the conducting end 40 is determined according to specific design needs.

[0052] In the above design of the conducting end 40, the conducting end 40 is electrically connected to the surface with the conductive contact through a metal material such as a wire, a metal wire, a metal strip, or a metal block. Figure 1 The dotted lines are used to illustrate, and other situations are not shown. That is, the conducting end 40 and the surface with the conductive contact can be set as one piece, or can be connected together by welding or the like, and then the hook body 100 is shaped and protected by wrapping the corresponding plastic shaping layer on the outside. In order to increase the strength of the hook body 100, the volume of the internal conductive metal can be appropriately increased. The specific structure is determined according to the design requirements, as long as it can achieve the corresponding function.

[0053] Among them, the sliding slope 11 is arranged facing the hook arm 20, and the reverse stop and hold surface 12 is arranged away from the hook arm 20. When the conductive hook is installed on the external connecting component, the sliding slope 11 and its positive projection on the horizontal plane are arranged at an acute angle, and the reverse stop and hold surface 12 coincides with its positive projection on the horizontal plane or is arranged at an acute angle. The sliding slope 11 is conducive to the forward sliding of the moving part and has a guiding effect. The sliding slope 11 is a smooth surface to reduce friction. The sliding slope 11 of the conductive hook is a plane, and the sliding slope 11 can also be a curved surface. When the sliding inclined surface 11 is subjected to a horizontal force, the conductive hook claw is compressed downward and moves circumferentially around the connecting axis. When the horizontal force is removed, the conductive hook claw can bounce upward. It can be understood that after the conductive hook claw is installed in the external connecting component, the spatial position of the connecting part 30 changes, causing the sliding inclined surface 11 and its projection on the horizontal plane to change. In the present invention, after the conductive hook claw is installed in the external connecting component, the conductive hook claw, the external connecting component and the reverse stop and support surface 12 are subjected to a horizontal force, and the relative position relationship of the three remains roughly unchanged, that is, the conductive hook claw can be installed and arranged in any space.

[0054] After the conductive hook is installed on the external connecting component, the orthographic projection of the sliding inclined surface 11 on the horizontal plane covers part or all of the orthographic projection of the reverse anti-receding abutting surface 12 on the horizontal plane. The connection between the hook portion 10 and the hook arm 20 is a curved connection, so that the hook portion 10 is higher than the hook arm 20. The reverse anti-receding abutting surface 12 extends towards the curved connection between the hook portion 10 and the hook arm 20, and the reverse anti-receding abutting surface 12 is recessed inward to form a hook groove 121. The orthographic projection of the sliding inclined surface 11 on the horizontal plane covers part of the orthographic projection of the bottom wall of the hook groove 121 on the horizontal plane, and their general extension directions are the same. The hook groove 121 can further limit the reverse movement of the moving part. When the rear end of the moving part slides past the hook portion 10, during the reverse movement of the moving part, the rear end of the moving part approaches the reverse anti-receding abutting surface 12 along the bottom wall of the hook groove 121 and is abutted. At the same time, it saves the material for manufacturing the hook portion 10 and reduces the cost. The hook body 100 is generally flat or columnar, or other shapes, such as the lower end of the hook body 100 is square-shaped, etc.

[0055] Among them, the closed loop formed by the first circuit and the second circuit includes a radio frequency IC chip and a radio frequency antenna. The radio frequency IC chip is located in the first circuit, and the radio frequency antenna board is located in the second circuit, or the radio frequency IC chip is located in the second circuit, and the radio frequency antenna board is located in the first circuit; or the radio frequency IC chip and the radio frequency antenna board are located in the first circuit, or the radio frequency IC chip and the radio frequency antenna board are located in the second circuit. When the first circuit and the second circuit are conducted through the conductive hook, the radio frequency IC chip can be read by the outside world. Of course, one conductive hook, or two conductive hooks, or more conductive hooks can be provided in the first circuit and the second circuit. Multiple conductive hooks can be connected simultaneously, or they can be conducted out of sync. For example, when the first circuit and the second circuit are conducted through the conductive hook, the radio frequency IC chip can be read by the outside world. Of course, the first circuit and the second circuit include a first conductive hook and a second conductive hook. When the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are conducted with two access points of the second circuit. Of course, both ends of the first conductive hook and the second conductive hook can also be respectively connected to two access points of the first circuit and the second circuit; for example two, the first circuit and the second circuit include a first conductive hook, a second conductive hook, a third conductive hook, and a fourth conductive hook. The first circuit is disconnected into two connecting circuits. The first conductive hook, the second conductive hook, the third conductive hook, and the fourth conductive hook in the first circuit and the second circuit are respectively electrically connected to four access points of the first circuit. When the moving part slides to the first preset distance, the first conductive hook and the second conductive hook are conducted with two access points of the second circuit. When the moving part slides to the second preset distance, the third conductive hook and the fourth conductive hook are conducted with two access points of the second circuit.

[0056] Understandably, in a device, multiple conductive hooks can be provided, and multiple circuits can be connected. In the moving part, two or more circuits can be provided. When the moving part slides to different preset distances, one or two devices are connected to the circuits in the moving part through the conductive hooks to achieve the positioning and sensing function, that is, corresponding functions are achieved according to different components provided in the circuit.

[0057] Please refer to Figure 1 and Figure 2 , further, the sliding inclined plane 11 intersects with the reverse anti-receding abutting surface 12 to form an intersecting free end 122. When the conductive hook is installed on the external connecting component, the highest points of the sliding inclined plane 11 and the reverse anti-receding abutting surface 12 are both located at the free end 122. The outer surface of the free end has a conductive contact. When the front end of the moving part slides over the sliding inclined plane 11, the surface of the free end 122 with the conductive contact abuts or contacts the moving part. The surface of the free end 122 is a smooth curved surface, and the curved surface includes a circular curved surface, an arc-shaped curved surface, and an elliptical curved surface. Reducing friction is beneficial to sliding, and the curved surface enables the free end 122 to fully contact the moving part during the sliding process. The sliding inclined plane 11 can be a plane, and the sliding inclined plane 11 can also be a curved surface. The curved surface is beneficial to guiding the moving part and increasing the guiding acceleration.

[0058] There can be other connection methods between the top end of the sliding inclined plane 11 of the hook part 10 and the reverse anti-receding abutting surface 12, that is, as long as the corresponding functions can be achieved. For example, the top end of the sliding inclined plane 11 and the top end of the reverse anti-receding abutting surface 12 are also connected through a contact surface. The contact surface is used to abut or contact the moving part. The contact surface is arranged as a plane or approximately a plane, so that the first circuit and the second circuit are electrically connected or conducted; or the sliding inclined plane 11 intersects with the reverse anti-receding abutting surface 12 to form a straight line or a curve.

[0059] Further, the conductive hook is connected to the external connecting component by an elastic connection method. During the movement of the moving part, it can move within a limited range. The elastic action of the conductive hook ensures the connection between the hook part 10 of the conductive hook and the moving part. If the conductive hook is fixedly connected to the external connecting component, when the moving part is separated from the hook part 10, the hook part 10 cannot move up and down to abut against the moving part, resulting in the interruption of the circuit connection. The external connecting component can be the main body of the device, a plate-shaped mounting part, or a mounting part with other shapes.

[0060] Please refer to Figure 1 and Figure 2, Further, the hook arm 20 is disposed substantially in a horizontal direction. The connection between the sliding inclined surface 11 and the upper surface of the hook arm 20 is a smooth curved surface connection, and the connection between the reverse anti-retreat abutting surface 12 and the lower surface of the hook arm 20 is a smooth curved surface connection. The hook portion 10 of the conductive hook is higher than the highest point of the hook arm 20. Of course, the hook arm 20 can also be provided in various shapes and directions as long as it can meet the usage requirements. For example, the hook arm 20 is inclined, and the upper surface abuts against an external connecting component to limit the upper movement range. The thickness, length, and structural design are increased according to the design and usage needs. The thickness can increase the strength of the conductive hook, and the length can increase the radial length. For example, in a larger device, the overall structure of the conductive hook is relatively large and the thickness is relatively large, that is, it is designed according to specific requirements.

[0061] Please refer to Figure 2 and Figure 3 , One end of the conduction end 40 electrically connected to an access point of the first circuit is located at the connection portion 30. The conduction end 40 is a protrusion protruding from the connection portion 30. A groove is further provided at the free end of the conduction end 40 to facilitate connection with the access point of the circuit. Generally, the wire of the circuit is welded to the conduction end 40 by welding. The provided groove is used for connection and at the same time protects the connection end from being damaged by external contact. The conduction end 40 is provided at the connection portion 30, with a beautiful overall structure, enhancing the strength of the connection portion 30, facilitating the elastic movement of the conductive hook, preventing contact with other structures, and the conduction end 40 is arranged in the elastic movement direction of the conductive hook.

[0062] Please refer to in combination Figure 4 and Figure 5 , Another design method of the conduction end 40. Further, the conduction end 40 can protrude from the hook arm 20; or, it can also be a groove recessed in the hook arm 20, and the conduction end 40 is located on the inner wall of the groove; or the conduction end 40 is located on the surface of the hook arm 20.

[0063] Please refer to Figures 3 to 7, Further, one design of the connecting portion 30 is that there is a metal ring or semi-ring inside the connecting portion 30, and the surface of the ring or semi-ring is covered with an insulating shaping layer 200. The connecting portion 30 is integrally or separately provided with the metal inside and the conducting end. The metal inside the connecting portion 30 enhances the strength of the connecting portion 30. There is a shaft hole 31 in the middle of the ring or semi-ring. The shaft hole 31 in the ring is a closed shaft hole, and the shaft hole 31 in the semi-ring is an open semi-circular shaft hole. The shaping layer 200 covers the surface of the ring or semi-ring. The ring or semi-ring has a certain supporting effect, and at the same time, it is convenient for the shaping layer 200 to be shaped and have holes. The shaping layer (not shown) on the surfaces of the hook arm 20 and the hook portion 10 can be integrally or separately provided with the shaping layer 200 on the surface of the connecting portion 30, which is convenient for the specific structure to be formed. The material of the shaping layer is a plastic material. Of course, it can also be other insulating layer materials, such as urea-formaldehyde resin, aniline-formaldehyde resin, melamine-formaldehyde resin, glycerol resin, silk, cotton yarn, cotton cloth, and their mixed products with a certain strength. Figure 7 As shown, there is a connecting post 201 on one side of the shaping layer 200, and a connecting hole 202 penetrating the connecting post 201 is provided in the middle of the shaping layer 200. The shaft hole 31 communicates with the connecting hole 202. Of course, connecting posts 201 can be provided on both sides of the shaping layer 200.

[0064] It can be understood that another design of the connecting portion 30 is that the connecting portion 30 is entirely constructed of a shaping layer, and it can be integrally or separately provided with the shaping layer 200 on the surface of the connecting portion 30.

[0065] Please refer to Figure 8 , A torsion spring 50 is sleeved on the connecting post 201. The conductive hook is sleeved on the connecting shaft 32 through the connecting hole 202. The connecting shaft 32 is installed and fixed on an external connecting component. One torsion arm of the torsion spring 50 is stuck in the torsion arm groove 203 provided on the connecting portion 30, and the other torsion arm is stuck on the external connecting component. The hook arm 20 of the conductive hook abuts against and is limited by the external connecting component, so that the torsion spring 50 generates a torsional force. When the hook portion 10 is pressed downwards, the torsion spring 50 further increases the torsional force, and the conductive hook makes a circumferential movement around the connecting shaft. When the acting force is removed, the conductive hook can bounce upwards and roughly return to the initial position.

[0066] Please refer to Figure 8 , Two or more conductive hooks are installed in the device. They can be connected and installed on an external connecting component or the device main body through a connecting shaft 32. Adjacent conductive hooks can be connected by a double torsion spring. The two torsion springs 50 are connected by their torsion arms, making the internal structure compact and saving space; or two or more connecting shafts 32 can be used. One or two conductive hooks are sleeved on each connecting shaft 32, and they can be arranged side by side in a row, or can be arranged in two rows, or multiple rows for installation.

[0067] Certainly, according to the requirements of device design or use, the torsion arm groove 203 is located in the shaping layer 200. The shaping layer 200 is convexly provided with a clamping position. The connection between the clamping position and the shaping layer 200 encloses the torsion arm groove 203. The clamping position and the shaping layer 200 can be integrally formed by an injection molding process, which is simple in processing and cost-saving. Of course, other connection methods such as bonding can also be used. The clamping position can also be located on the metal inside the connecting part 30 and protrude from the surface of the shaping layer, which is firm and durable and not easily deformed. The clamping position can also have two or more, and the torsion of the torsion spring 50 can be adjusted according to the use requirements. According to the requirements of device design or use, the shaping layer 200 can also be provided with two connecting columns 201 located on both sides respectively, and the two connecting holes 202 in the two connecting columns 201 are communicated with each other.

[0068] Please refer to Figure 9 , another elastic connection structure of the connecting part 30. Connecting shafts 32 are formed on both sides of the connecting part 30, and the connecting shafts 32 are integral with the metal inside the connecting part 30. The connecting shafts 32 can be made integral with the metal inside the connecting part 30 through processing or welding, etc. The surface of the connecting shafts 32 can be painted or provided with a relatively thin insulating layer. Of course, the external connecting components can also be made of insulating materials. The conducting end 40 is located in the connecting part 30 or the hook arm 20 and is set according to the design requirements, which will not be introduced one by one here; or, the connecting shafts 32 are formed on the shaping layer 200, and the shaping layer 200 is penetrated by the connecting shafts 32. One end of the connecting shaft 32 is installed in a mounting hole (not shown) of an external connecting component and has a clearance fit. A torsion spring 50 is sleeved on both ends or one end of the connecting shaft 32. One straight torsion arm of the torsion spring 50 is stuck on the connecting part 30, and the other straight torsion arm is stuck on the external connecting component. Corresponding clamping positions are provided on the external connecting component, so that the conducting hook claws are elastically arranged on the external connecting component, and the connecting shaft 32 is insulated from the mounting hole. The connecting shaft 32 can rotate freely. Adjacent conducting hook claws can be fixed together through the connecting shaft 32, so that the movements of the conducting hook claws are synchronized, which is convenient for unified control, makes the device work stably, and saves installation space. The hook arm 20 of the conducting hook claw abuts against and is limited by the external connecting component, so that the torsion spring 50 generates torsion. When the clamping hook part 10 is pressed downwards, the torsion spring 50 further increases the torsion, and the conducting hook claw makes a circumferential movement around the connecting shaft 32. When the acting force is removed, the conducting hook claw can bounce upwards and roughly return to the initial position.

[0069] The technical solution of the present invention realizes the electrical connection between the first circuit electrically connected to the conduction end and the second circuit access point of the moving member through the conductivity of the hook body itself, the elastic connection method, and the reverse anti-retreat abutting surface provided on the hook portion. When the moving member presses the hook portion and moves forward along the sliding inclined surface, when the hook portion abuts or contacts the second circuit access point, it is conducted. When the moving member moves in the reverse direction, the reverse anti-retreat abutting surface engages with the moving member to prevent the moving member from continuing to move, realizing the one-way movement function of the conductive hook. The connecting portion is connected to the external connecting member through an elastic connection method. During the process that the moving member presses the conductive hook and moves in the horizontal direction, it is ensured that the hook portion always abuts the moving member, enabling the stable connection between the first circuit and the second circuit, facilitating the movement of the moving member, and realizing the corresponding positioning and signal transmission sensing functions.

[0070] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
