[0033] like Figure 1-8 As shown, an assembled multifunctional key comprises a key body, which comprises a key head 1, a head core plate 2, a connecting piece 3, and a key blank 4; a receiving cavity 101 is arranged on the inner side of the key head 1, the head core plate 2 is arranged in the receiving cavity 101, and a disassembly opening communicating with the receiving cavity 101 is arranged on the side wall of the key head 1; a horizontally arranged slide groove 201 is arranged on the front side of the head core plate 2, and a first strip-shaped protrusion 102 adapted to the slide groove 201 is arranged on the inner wall of the receiving cavity 101; a storage groove 202 is arranged on the rear side of the head core plate 2; and a slot for storing items 202 is arranged at the lower part of the key head 1 A mounting hole passes through the connecting member 3, and the mounting hole is connected to the accommodating cavity 101. A second strip-shaped protrusion 301 is arranged in a transverse direction on the upper part of the connecting member 3, and a card groove 206 matched with the second strip-shaped protrusion 301 is arranged on the front side of the head core plate 2, and the card groove 206 is arranged below the slide groove 201; an insertion groove for inserting the key embryo 4 is provided at the lower part of the connecting member 3, and a through groove 401 is provided at the upper part of the key embryo 4, and a pin hole matched with the through groove 401 is provided on the side wall of the connecting member 3, and then the key embryo 4 is connected to the connecting member 3 through the pin 5, and the pin 5 is located on the inner side of the mounting hole. This design is convenient for assembly and disassembly and easy to use. Through the cooperation of the key head 1, the head core plate 2, the connector 3 and the key embryo 4, the key head 1 and the key embryo 4 can be quickly disassembled and assembled, which is beneficial for key replacement or repair and reduces resource waste. Moreover, the space is reasonably utilized so that some tiny products in daily life can be placed in the key head 1, such as chips, which can be easily carried and improve the key usage experience.

[0034] In order to ensure the use effect of the key, the key head 1, the head core plate 2 and the connecting piece 3 are all made of plastic. The key head 1, the head core plate 2 or the connecting piece 3 made of plastic have a certain elasticity, which is conducive to the disassembly and assembly of the key body. Preferably, the key head 1, the head core plate 2 and the connecting piece 3 can be made of one of ABS, PVC, PPR, PEEK and PPS materials.

[0035] The disassembly and assembly port is arranged on the left side wall of the key head 1, and an opening connected to the accommodating cavity 101 is arranged on the right side wall of the key head 1. A columnar protrusion 203 adapted to the opening is provided on the head core plate 2, so that the columnar protrusion 203 can facilitate the user to push out the head core plate 2. The user can use tools such as a card removal pin and a toothpick to push the columnar protrusion 203, thereby driving the head core plate 2 to be removed from the key head 1.

[0036] A first magnet is provided on a side wall of the head core plate 2 away from the disassembly and assembly port, and a second magnet adsorbed with the first magnet is provided on the inner wall of the accommodating cavity 101, so as to facilitate the installation of the head core plate 2 into the accommodating groove of the key head 1, especially in the process of assembling the key body, the mutual adsorption of the first magnet and the second magnet can prevent the head core plate 2 from slipping before the connector 3 enters and is pushed into the installation hole, thereby avoiding the loss of small products placed in the storage groove 202 of the head core plate 2. Preferably, there are two first magnets, which are respectively arranged on the upper and lower sides of the columnar protrusion 203, and two second magnets are provided on the inner wall of the accommodating cavity 101.

[0037] The thickness of the upper part of the connecting member 3 is smaller than the thickness of the lower part of the connecting member 3. The lower part of the head core plate 2 is provided with a stepped groove 204 adapted to the upper part of the connecting member 3. The card groove 206 is arranged on the inner wall of the stepped groove 204 to facilitate the fixation between the connecting member 3 and the head core plate 2. This structure can avoid increasing the volume of the key head 1 and ensure the use effect of the key body.

[0038] The right side of the stepped groove 204 is provided with a sliding outlet, which is arranged on a side surface of the head core plate 2 close to the columnar protrusion 203, and the length of the slot 206 is the same as that of the stepped groove 204; a block 205 for resisting the upper end of the connecting member 3 is arranged in the stepped groove 204, and the cross section of the block 205 is an inverted triangle, and a slot is arranged above the block 205, so that the block 205 can play an anti-return effect on the head core plate 2. When the connecting member 3 is pushed into the installation hole, in the process of the head core plate 2 moving into the accommodating cavity 101, the block 205 will resist the connecting member 3 and slide with the help of the elastic deformation of the material itself. After the head core plate 2 is completely placed in the accommodating cavity 101, the block 205 is reset. In the absence of external force, the block 205 will play a limiting role on the head core plate 2. In order to further facilitate the disassembly and assembly of the self-key body, the upper end of the connecting member 3 is provided with an inclined contact surface adapted to the block 205.

[0039] A vertically arranged strip groove is provided on the inner wall of the mounting hole, and a third strip protrusion 302 adapted to the strip groove is provided on the side wall of the connecting piece 3. The third strip protrusion 302 facilitates the user to distinguish between the positive and reverse directions, thereby preventing misalignment and facilitating the user to push the connecting piece 3 into the mounting hole to smoothly achieve a fixed connection between the connecting piece 3 and the head core plate 2.

[0040] In order to facilitate the head core plate 2 to be pushed into the accommodating cavity 101 of the key head 1, the width of the opening of the slide groove 201 is greater than the width inside the slide groove 201, that is, the width of the opening of the slide groove 201 gradually increases from left to right. In addition, the thickness of the left side of the first strip protrusion 102 gradually increases from left to right.

[0041] The storage slot 202 includes a first storage slot and a second storage slot arranged in parallel. A GPS positioning chip is provided in the second storage slot near the disassembly port, so that the user can store small products and find the key body easily.

[0042] When assembling the key body, the pin 5 is inserted into the pin hole on the connecting member 3 and penetrates the through groove 401 on the key embryo 4 to fix the key embryo 4 to the connecting member 3, and the connecting member 3 is pushed upward into the mounting hole at the lower part of the key head 1, and then the head core plate 2 is pushed in from the disassembly and assembly port, and enters the slide groove 201 through the first strip protrusion 102, so that the head core plate 2 enters the accommodating cavity 101 of the key head 1 along the direction of the first strip protrusion 102, and the second strip protrusion 301 on the upper side of the connecting member 3 is inserted into the groove 206 on the lower side of the head core plate 2. At the same time, the block 205 in the stepped groove 204 restricts the connecting member 3. The connecting piece 3 is fixedly connected to the head core plate 2 to complete the assembly of the key body; when the key body is disassembled, the columnar protrusion 203 on the head core plate 2 is pushed, so that the columnar protrusion 203 drives the head core plate 2 to move from the disassembly port to the outside of the key head 1, so that the block 205 and the connecting piece 3 slip, prompting the connecting piece 3 to detach from the head core plate 2 from the sliding port of the stepped groove 204 along the direction of the card groove 206, thereby taking the head core plate 2 out of the accommodating cavity 101, and then taking the connecting piece 3 downward from the mounting hole, pulling out the pin 5 from the pin hole on the connecting piece 3, so that the connecting piece 3 is separated from the key embryo 4, and the disassembly of the key body is completed.

[0043] The assembled multifunctional key provided by the present invention has the following beneficial effects:

[0044] (1) Easy to disassemble and assemble. The key body can be quickly disassembled and assembled through the structural design of the key head, head core plate, connector, key embryo and other components, and the assembled key body has sufficient firmness;

[0045] (2) Reasonable use of space. A storage slot is provided on the head core board to place small products, such as GPS positioning chips, mobile phone cards, memory cards, etc., which increases the functionality of the key and improves the use effect of the key;

[0046] (3) The hidden push-out structure allows the core plate to be removed from the key head by pushing the cylindrical protrusion with the help of common tools such as a card removal pin or toothpick, making it easier to remove and install the key body.

[0047] (4) It has a magnetic attraction and anti-drop function. With the help of the mutual adsorption of the first magnet and the second magnet, it can prevent the key body from falling off during the assembly process, thereby ensuring the smooth assembly of the key body;

[0048] (5) An advance-proof and retreat-proof structure is provided. With the aid of a card block with an inverted triangular cross section and the elastic deformation of the material itself, the head core plate can be smoothly pushed in and limit the head core plate without external force.

[0049] (6) An anti-dislocation structure is provided. By providing a third strip-shaped protrusion, the user can quickly distinguish between the positive and reverse directions, so that after the connector is installed in place, it can be smoothly pushed into the head core plate to achieve a fixed connection between the connector and the head core plate.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
