[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] The embodiments of the electrical connection interface, the electrical connection seat and the electrical equipment provided by the present application will be described below with reference to the drawings.

[0038] In one embodiment of the electrical connection interface of the present application, referring to Figure 5 and Figure 6 the electrical connection interface 10 is used to realize electrical connection with the electrical connection seat 20 to realize transmission of electric quantity through the connection of the two, to perform charging and discharging, or to realize transmission of various electrical signals such as control signals.

[0039] Referring to Figures 1-7 the electrical connection interface 10 includes a housing 11, a sliding block 12, an elastic plug 13 and a first conductive body 14.

[0040] The shell 11 has a first surface 110. The first surface 110 specifically refers to a side surface of the electric connection interface 10 at the position where the electric connection interface 10 and the electric connection end 20 are connected when the electric connection is implemented. An inner cavity 15 is formed in the shell 11, and various components are arranged in the inner cavity 15, such as circuits and related electrical components for implementing charging and discharging.

[0041] The sliding block 12 is mounted on the shell 11 and is in sliding connection with the shell 11. Specifically, the sliding path of the sliding block 12 or the extension line direction thereof passes through the first surface 110, in other words, the sliding block 12 will displace in the direction perpendicular to the first surface 110.

[0042] The first conductive body 14 is arranged on the sliding block 12. The first conductive body 14 is generally metal, for example, copper, iron, etc. The material of the sliding block 12 is insulating material, for example, plastic. The sliding block 12 and the first conductive body 14 can be formed into an integrated structure through, for example, injection molding process.

[0043] The elastic plug 13 is arranged in a cavity 16 formed between the sliding block 12 and the shell 11. The elastic plug 13 has a first side in sealing connection with the sliding block 12 and a second side in sealing connection with the shell 11. The elastic plug 13 divides the cavity 16 into a first space 161 and a second space 162 which are in sealing isolation. The elastic plug 13 can be made of waterproof silica gel or sponge, etc.

[0044] In this embodiment, the cavity 16 is divided into a first space 161 and a second space 162 by the elastic plug 13, which is in sealing connection with the sliding block 12 on one side and with the shell 11 on the other side, and the first space 161 and the second space 162 are not in communication with each other and have a sealing isolation relationship. Meanwhile, the first space 161 and the second space 162 have the following relationship: of the two, one is opposite to the other with respect to the joint between the shell 11 and the sliding block 12 and with respect to the space outside the shell 11, and the other is opposite to the other with respect to the joint between the shell 11 and the sliding block 12 and with respect to the inner cavity 15 of the shell 11. The one opposite to the other with respect to the joint between the shell 11 and the sliding block 12 and with respect to the space outside the shell 11 is the first space 161, and the one opposite to the other with respect to the joint between the shell 11 and the sliding block 12 and with respect to the inner cavity 15 of the shell 11 is the second space 162. When the electrical connection interface 10 is not in electrical connection with the electrical connection seat 20, and when it is in electrical connection with the electrical connection seat 20, water in the space outside the shell 11 enters the first space 161 through the joint between the shell 11 and the sliding block 12, and is blocked or absorbed by the elastic plug 13, and cannot continue to enter the second space 162 and enter the inner cavity 15 of the shell 11 through the joint between the shell 11 and the sliding block 12, so that the electrical elements arranged in the inner cavity 15 can be prevented from contacting water and causing damage to related devices and equipment and dangerous accidents.

[0045] In the initial state of the elastic plug 13, when the first conductive body 14 is in contact with the second conductive body 22 on the electrical connection seat 20, there is a gap between the first surface 110 of the shell 11 and the second surface 210 of the seat body 21 of the electrical connection seat 20.

[0046] In this embodiment, the initial state of the elastic plug 13 refers to a state in which the electrical connection interface 10 is not in electrical connection with the electrical connection seat 20, and the sliding block 12 and the first conductive body are not subjected to other external forces. In this state, the elastic plug 13 can be in a natural state, i.e., without elastic force, or in a state of being compressed or stretched, i.e., with elastic force. Preferably, the initial state of the elastic plug 13 is set to a state of being compressed or stretched to have a certain elastic force. When the elastic plug 13 has a certain elastic force, the elastic plug 13 can be in closer contact with the shell 11 and the sliding block 12, so that better sealing can be achieved between the elastic plug 13 and the shell 11 and between the elastic plug 13 and the sliding block 12, and the first space 161 and the second space 162 can be better sealed and isolated.

[0047] In this embodiment, the top end of the first conductive body 14 can be arranged to protrude from the surface of the sliding block 12, and the sliding block 12 can be arranged to be flush with the first surface 110 in the initial state of the elastic plug 13. With the above arrangement, the top end of the first conductive body 14 can be ensured to be higher than the first surface 110 in the initial state of the elastic plug 13. In this case, if the top end of the second conductive body 22 on the electrical connection seat 20 is flush with the second surface 210 of the seat body 21, the second conductive body 22 and the first conductive body 14 can be in contact before the first surface 110 and the second surface 210 are in contact when the electrical connection interface 10 and the electrical connection seat 20 are electrically connected and close to each other, thereby ensuring that there is a gap between the first surface 110 of the shell 11 and the second surface 210 of the seat body 21 of the electrical connection seat 20 when the first conductive body 14 contacts the second conductive body 22 on the electrical connection seat 20 in the initial state of the elastic plug 13.

[0048] In this embodiment, the top end of the first conductive body 14 can be arranged to protrude from the surface of the sliding block 12, and the sliding block 12 can be arranged to be flush with the first surface 110 in the initial state of the elastic plug 13. With the above arrangement, the top end of the first conductive body 14 can be ensured to be higher than the first surface 110 in the initial state of the elastic plug 13. In this case, if the top end of the second conductive body 22 on the electrical connection seat 20 is flush with the second surface 210 of the seat body 21, the second conductive body 22 and the first conductive body 14 can be in contact before the first surface 110 and the second surface 210 are in contact when the electrical connection interface 10 and the electrical connection seat 20 are electrically connected and close to each other, thereby ensuring that there is a gap between the first surface 110 of the shell 11 and the second surface 210 of the seat body 21 of the electrical connection seat 20 when the first conductive body 14 contacts the second conductive body 22 on the electrical connection seat 20 in the initial state of the elastic plug 13.

[0049] In this embodiment, when the electrical connection interface 10 and the electrical connection seat 20 are electrically connected, the two are brought close to each other, the first conductive body 14 and the second conductive body 22 will first contact together; after the two are contacted, the electrical connection interface 10 and the electrical connection seat 20 continue to be close, until the first surface 110 of the shell 11 and the second surface 210 of the seat body 20 are contacted together. In the process of this continuous close, the elastic force of the elastic plug 13 will be overcome, the elastic force of the elastic plug 13 will act on the sliding block 12 and the first conductive body 14 provided on the sliding block 12, so that the first conductive body 14 is tightly abutted on the second conductive body 22, that is, the stable connection between the first conductive body 14 and the second conductive body 22 can be maintained.

[0050] In this embodiment, the first side of the elastic plug 13 is sealingly connected with the sliding block 12, and the second side is sealingly connected with the shell 11. Specifically, grooves can be respectively provided on the sliding block 12 and the shell 11, the first side and the second side of the elastic plug 13 are respectively inserted into the corresponding grooves, and can be tightly matched with the grooves, so that sealing can be achieved at the connection.

[0051] For the elastic plug 13, when the elastic plug 13 is in a compressed or stretched state, it has a resilience that can make the first side and the second side of the elastic plug 13 more tightly connected between the sliding block 12 and the shell 11, and obtain better sealing performance. When the electrical connection interface 10 and the electrical connection seat 20 are electrically connected and brought close to each other to the first surface 110 and the second surface 210 are contacted, as described above, the elastic force of the elastic plug 13 will be overcome, that is, the elastic plug 13 will be further deformed by the acting force, and can have a greater resilience, which helps to better maintain the sealing connection between the sliding block 12 and the shell 11 of the elastic plug 13, thereby better sealingly isolating the first space 161 and the second space 162.

[0052] In an embodiment of the electrical connection interface, the shell 11 is provided with a first magnetic attraction part 111, which is adjacent to the first surface 110 of the shell 11, for magnetically attracting the first surface 110 of the shell 11 to the electrical connection seat 20.

[0053] Corresponding to the first magnetic attraction part 111 provided on the shell 11, the second magnetic attraction part 211 can also be provided on the electrical connection seat 20, and when electrically connected, the first magnetic attraction part 111 and the second magnetic attraction part 211 generate an attractive force acting on the shell 11 and the seat body 21, bringing the first surface 110 and the second surface 210 of the two into contact.

[0054] In this embodiment, the housing 11 of the electrical connection interface 10 is magnetically attracted and fixed to the electrical connection seat 20 by the first magnetic attraction part 111. On the one hand, when electrical connection is performed, the electrical connection interface 10 does not need to be held by hand and moved by force, and the hand does not need to exert force to overcome the elastic force of the elastic plug 13, so that the electrical connection of the two can be more convenient and labor-saving. On the other hand, the magnetic attraction can also play a positioning role, so that the electrical connection interface 10 and the electrical connection seat 20 do not need to be accurately aligned when electrical connection is performed, so that the electrical connection process can be more convenient. In addition, the magnetic attraction force of the first magnetic attraction part 111 can also continuously overcome the elastic force of the elastic plug 13 when maintaining the electrical connection state, so as to maintain the stable connection between the first conductive body 14 and the second conductive body 22 by contacting the first surface 110 and the second surface 210.

[0055] In one embodiment of the electrical connection interface, in the first space 161 and the second space 162, in the first space 161, the housing 11 and the sliding block 12 have a joint that communicates with the space outside the housing 11; in the second space 162, the housing 11 and the sliding block 12 have a joint that communicates with the inner cavity 15 of the housing 11. In the second space 162, the joint is provided with a ring-shaped convex edge 112 that protrudes into the second space 162.

[0056] In this embodiment, if water from the space outside the housing 11 enters the first space 161 and breaks through the sealing isolation of the elastic plug 13 to enter the second space 162, the ring-shaped convex edge 112 can block the water from entering the joint between the housing 11 and the sliding block 12 in the second space 162, thereby preventing the water from entering the inner cavity 15 of the housing 11 and further ensuring that the electrical components arranged in the inner cavity 15 will not be in contact with water.

[0057] In one embodiment of the electrical connection interface, the sliding block 12 is provided with a stop block 120, which is located in the inner cavity of the housing 11 and protrudes into the inner cavity of the housing 11 in a direction intersecting the sliding path of the sliding block 12.

[0058] In this embodiment, the stop block 120 can play a limiting role to limit the maximum distance of the sliding block 12 moving outward from the first surface 110. Specifically, the stop block 120 can limit the sliding block 12 to a state where the surface of the sliding block 12 is flush with the first surface 110; that is, under the limiting action of the stop block 120, the surface of the sliding block 12 can only be flush with or lower than the first surface 110, and will not be higher than the first surface 110.

[0059] In one embodiment of the electrical connection interface, as described above, the top end of the first conductor 14 can protrude from the surface of the sliding block 12. Specifically, the height of the top end of the first conductor 14 protruding from the surface of the sliding block 12 is no more than 0.3 mm. When the electrical connection interface 10 is electrically connected with the electrical connection seat 20, the travel of the force of the elastic plug 13 deforming the elastic plug 13 is 0.3 mm, and under the travel, the elastic plug 13 has a rebound force that can meet the requirement of tightly sealing the connection between the shell 11 and the sliding block 12.

[0060] In one embodiment of the electrical connection interface, the elastic plug 13 is a columnar ring structure, and the waist between the top end and the bottom end of the elastic plug 13 is arc-shaped.

[0061] In this embodiment, the waist between the top end and the bottom end of the elastic plug 13 is arc-shaped, which can make the elastic plug 13 have a better rebound force, so as to achieve a tighter connection with the shell 11 and the sliding block 12, and thus achieve a better sealing at the joint.

[0062] In summary, the electrical connection interface provided by the above embodiments of the present application has the first side of the elastic plug 13 sealingly connected with the sliding block 12, and the second side sealingly connected with the shell 11. The cavity 16 is divided into the first space 161 and the second space 162 by the elastic plug 13, and the first space 161 and the second space 162 are not communicated with each other and have a sealed and isolated relationship. When the electrical connection interface 10 is not electrically connected with the electrical connection seat 20, and when it is electrically connected with the electrical connection seat 20, the water in the space outside the shell 11 enters the first space 161 through the joint between the shell 11 and the sliding block 12, and is blocked by the elastic plug 13 and cannot continue to enter the second space 162 and the inner cavity 15 of the shell 11 through the joint between the shell 11 and the sliding block 12, so as to ensure that the electrical components arranged in the inner cavity 15 are not in contact with water, and thus the damage and dangerous accidents of related devices and apparatuses are avoided.

[0063] In one embodiment of the electrical connection seat of the present application, the electrical connection seat 20 includes a seat body 21 and a second conductor 22. The seat body 21 has a second surface 210. The second conductor 22 is embedded in the seat body 21, and the end of the second conductor 22 is exposed from the second surface 210.

[0064] The electrical connection seat in the embodiments of the present application cooperates with the electrical connection interface 10 in the above embodiments, has the same beneficial effects as the electrical connection interface 10 described above, and will not be described again.
