[0002] In the related art, when the mowing robot is recharged, the charging port of the mowing robot is connected to the charging tongue of the base station. The current charging port has a closed type and an open type in terms of movement mode. The closed type means that the charging port can be closed when not in use. The open type means that the charging port is exposed when not in use. However, the structure of the closed type is relatively complex, and the open type with a simple structure requires the pre-press contact between the pole piece of the charging port and the charging tongue. For example, the pre-press contact with the charging tongue is achieved by using the elastic deformation of the pole piece itself. When the charging port approaches the charging tongue, the pole piece will deform to a certain extent due to its own elastic properties, thereby making contact with the charging tongue. However, this design requires precise control of the elastic properties and shape of the pole piece material to ensure good contact under different use conditions.

[0037] As shown in Figure 1 , Figure 2 and Figure 3 , some embodiments of the utility model disclose a charging port structure 1, which comprises a cavity 11, an elastic member 12 and an electrode member 13, and specifically as follows:
[0038] One end of the cavity 11 has an opening 111. The electrode member 13 is abutted in the cavity 11 through the elastic member 12 and the inner wall surface opposite to the opening 111. The electrode member 13 extends from the inside of the cavity 11 to the opening 111, forming an open charging port 130. The electrode member 13 has a first working state as shown in Figure 3 and a second working state as shown in Figure 4 , and the elastic member 12 has a first compression state as shown in Figure 3 and a second compression state as shown in Figure 4 .
[0039] Among them, as shown in Figure 3As shown, when the electrode piece 13 is in the first working state, the elastic piece 12 is in the first compressed state, and the elastic piece 12 continuously applies the pre-pressing force to the electrode piece 13, so that the electrode piece 13 is clamped in the cavity 11.
[0040] As shown, when the electrode piece 13 is in the first working state, the elastic piece 12 is in the first compressed state, and the elastic piece 12 continuously applies the pre-pressing force to the electrode piece 13, so that the electrode piece 13 is clamped in the cavity 11. Figure 4 As shown, when the electrode piece 13 is in the first working state, the elastic piece 12 is in the first compressed state, and the elastic piece 12 continuously applies the pre-pressing force to the electrode piece 13, so that the electrode piece 13 is clamped in the cavity 11.
[0041] It should be noted that the deformation of the electrode piece 13 is caused by the insertion of the external element into the open charging port 130, and the pre-pressing force generated by the elastic piece 12 in the second compressed state is greater than the pre-pressing force generated by the elastic piece 12 in the first compressed state. For example, the elastic piece 12 is a compression spring, which is only an example and does not limit the present application, and can also be other.
[0042] The charging port structure 1 of the embodiment has two pre-pressing forces, one from the compression of the elastic piece 12, and the other from the deformation of the electrode piece 13, thereby realizing multi-directional pre-pressing and ensuring good contact between the external element and the electrode piece 13. Moreover, the electrode piece 13 can move towards the inside of the cavity 11 to increase the activity space of the electrode piece 13 and improve the success rate of charging at different angles.
[0043] As shown in some embodiments, Figure 1 , Figure 2 and Figure 3 , the charging port structure 1 further comprises a shell 14 and a pressing plate 15, the pressing plate 15 is installed on the shell 14, and the shell 14 and the pressing plate 15 jointly define the cavity 11. Figure 3 As an example, the pressing plate 15 is located above, and the shell 14 is located below, and the two are embedded to jointly define the cavity 11.
[0044] As shown in some embodiments, Figure 2 and Figure 3 , the electrode piece 13 comprises a base 131 and at least two oppositely spaced conductive arms 132, which can be two, three or any number. The base 131 has two opposite surfaces, and the conductive arms 132 are arranged on one surface of the base 131 and extend to the opening 111 of the cavity 11 to form the open charging port 130. The elastic piece 12 abuts against the other surface of the base 131 and the inner wall surface of the cavity 11 opposite to the opening 111.
[0045] For example, the base 131 is parallel to the plane where the opening 111 of the cavity 11 is located, and the elastic member 12 is perpendicular to the plane where the opening 111 of the cavity 11 is located. In addition, the base 131 and the conductive arm 132 form a "U" shaped structure, the base 131 and the conductive arm 132 are integrally formed, and the base 131 and the conductive arm 132 are conductive bodies made of metal materials, for example, copper or the like. Here, the copper is only an example and does not limit the present application.
[0046] In some embodiments, as shown in Figure 3 and Figure 4 , the conductive arm 132 includes an elastic portion 1321, a clamping portion 1322 and a guide portion 1323 connected in sequence from inside the cavity 11 to the opening 111, the elastic portion 1321 has a normal state as shown in Figure 3 and a deformed state as shown in Figure 4 .
[0047] As shown in Figure 3 , when the electrode member 13 is in the first working state, the elastic portion 1321 is in the normal state, the clamping region A is spaced between the at least two clamping portions 1322, the guide portion 1323 is used to guide the external element to be inserted into the clamping region A, and the elastic member 12 is in the first compressed state, the elastic member 12 continuously applies a pre-pressure to the electrode member 13 to make the elastic portion 1321 clamped in the cavity 11.
[0048] As shown in Figure 4 , during the process of switching the electrode member 13 from the first working state to the second working state, the elastic portion 1321 is in the deformed state, the clamping portion 1322 has a pre-pressure towards the clamping region A, and the electrode member 13 moves towards the inside of the cavity 11 to increase the activity space of the electrode member 13, while the elastic member 12 is in the second compressed state, the elastic member 12 continuously applies a pre-pressure to the electrode member 13.
[0049] In some embodiments, the clamping portion 1322 and the guide portion 1323 are also elastic bodies, that is, the entire conductive arm 132 is an elastic body. Therefore, when the external element is inserted into the clamping region A, the clamping portion 1322 can also be deformed.
[0050] In some embodiments, as shown in Figure 3 and Figure 4 , the shape of the inner wall surface of the cavity 11 is matched with the shape of the elastic portion 1321, the clamping portion 1322 and the guide portion 1323. For example, the elastic portion 1321 is an inclined surface, the clamping portion 1322 is a horizontal surface, the guide portion 1323 is an inclined surface, and the elastic portion 1321 and the guide portion 1323 respectively extend in the direction away from the clamping region A, so that the at least two guide portions 1323 form an eight-shaped opening 111.
[0051] Correspondingly, the inner wall surface of the cavity 11 corresponding to the position of the elastic part 1321 is an inclined surface, the inner wall surface of the cavity 11 corresponding to the position of the clamping part 1322 is a horizontal surface, and the inner wall surface of the cavity 11 corresponding to the position of the guide part 1323 is an inclined surface. Therefore, the clamping of the elastic part 1321 in the cavity 11 specifically means that the inclined surface of the elastic part 1321 is attached to the inclined inner wall surface of the cavity 11 at the corresponding position. It should be noted that the vertical direction is the plane where the opening 111 of the cavity 11 is located, the horizontal direction is perpendicular to the plane where the opening 111 of the cavity 11 is located, and the inclined direction has an angle with the horizontal direction.
[0052] As shown in some embodiments, Figure 2 and Figure 3 The electrode piece 13 further includes a wiring terminal 133 for connecting the wire, the wiring terminal 133 is arranged on the base 131 to be away from the opening 111 of the cavity 11, and the wiring terminal 133 can move with the base 131 in the direction from the inside of the cavity 11 to the opening 111, so that the displacement of the wiring terminal 133 is very small, which is beneficial to protect the wire from being easily broken.
[0053] As shown in some embodiments, Figure 2 The electrode piece 13 is an electrode sheet extending along the width direction of the opening 111 of the cavity 11, that is, when the electrode sheet is as wide as possible, the allowable error of alignment can be improved, so that the external element can contact the electrode piece 13 within the horizontal error range.
[0054] As shown in some embodiments, Figure 5 The utility model discloses some embodiments of an electronic device 2, including at least one charging port structure 1 described in any of the above embodiments, and it can be understood that at least one can be one, two, three or any number. For example, the electronic device 2 is a lawn mowing robot, and the lawn mowing robot here is only an example and does not limit the application, and it can also be other.
[0055] As shown in some embodiments, Figure 5 and 6 The utility model discloses some embodiments of an electronic system, including the electronic device 2 and the charging base station 3 described in the above embodiments.
[0056] The charging base station 3 has at least one charging tongue 31 protruding outward, and it can be understood that at least one can be one, two, three or any number. For example, as shown in some embodiments, Figure 7 The charging base station 3 is fixed to the ground, and the electronic device 2 can automatically move in front of the charging tongue 31 of the charging base station 3 when it needs to be charged, so that the charging tongue 31 is inserted into the open charging port 130 to realize charging.
[0057] In summary: as Figure 3As shown, before the electronic device 2 is charged, the electrode piece 13 is abutted against the inner wall surface opposite to the opening 111 in the cavity 11 through the elastic piece 12, at this time, the electrode piece 13 is in the first working state (i.e. the state of not being inserted into the charging tongue 31), the elastic part 1321 is in the normal state, the interval of the at least two clamping parts 1322 is the clamping area A, the guide part 1323 is used for guiding the external element to be inserted into the clamping area A, the elastic piece 12 is in the first compression state, and the elastic piece 12 continuously applies the pre-pressure to the base 131 of the electrode piece 13, so that the elastic part 1321 of the electrode piece 13 is clamped in the cavity 11.
[0058] As shown in Figure 6 and Figure 7 As shown, when the electronic device 2 needs to be charged, the electronic device 2 is automatically moved to the front of the charging tongue 31 of the charging base 3, the charging tongue 31 is inserted into the open charging port 130 of the electronic device 2, the charging tongue 31 is in contact with the electrode piece 13, at this time, the elastic part 1321 is in the deformed state in the process that the electrode piece 13 is switched from the first working state to the second working state, so that the clamping part 1322 has the pre-pressure towards the clamping area A, so that the electrode piece 13 and the charging tongue 31 can be effectively attached, and the electrode piece 13 is pushed to the rear by the charging tongue 31 and moves towards the inside of the cavity 11, so as to increase the activity space of the electrode piece 13, to adapt to the recharging at different angles and the change of the center distance, so that the charging tongue 31 can be pushed to the electrode piece 13 in all directions, and the elastic piece 12 is in the second compression state, the elastic piece 12 continuously applies the pre-pressure to the base 131 of the electrode piece 13, and further guarantees the effective attachment of the electrode piece 13 and the charging tongue 31.
[0059] When the electronic device 2 exits the charging base 3, the charging tongue 31 is separated from the electrode piece 13, and the electrode piece 13 and the elastic piece 12 return to the original position, that is, the electrode piece 13 returns to the first working state, and the elastic piece 12 returns to the first compression state.
[0060] By implementing the utility model, the following beneficial effects are achieved:
