Description

Technical Field

[0001] The present disclosure relates to the field of charging connection structures, and in particular, to a charging socket, a charging connector assembly and a robot. Background Art

[0002] The charging connection device in the related technology usually includes a charging socket and a charging plug. The charging plug is plugged into the charging socket to realize current exchange. Since the charging socket and the charging plug need to be accurately plugged in, when the charging device is applied to the robot, the robot automatically moves to the robot charging device (such as a charging seat or charging pile). However, due to technical limitations on the robot's position detection accuracy and movement control accuracy, the robot usually cannot guarantee to approach the robot charging device with a completely accurate posture, resulting in the charging plug or charging socket on the robot being unable to accurately dock with the charging socket or charging plug on the robot charging device, thereby causing the robot to charge failure.

DETAILED DESCRIPTION

[0042] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0043] In the present disclosure, unless otherwise stated, directional terms such as "first direction" refer to Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 8 The first direction shown in FIG. 1 and the second direction shown in FIG. 1 are Figure 1 The second direction shown in the figure, and the “third direction” refers to the Figure 2 , Figure 5 , Figure 6 and Figure 8 In the third direction shown, "inside" and "outside" refer to the inside and outside of the outline of the relevant parts. In addition, it should be noted that the terms used, such as "first", "second", etc., are used to distinguish one element from another element, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0044] like Figures 1 to 8As shown, the first aspect of the present disclosure provides a charging socket 10, which includes a positive electrode plug-in portion 1 and a negative electrode plug-in portion 2. The positive electrode plug-in portion 1 includes at least three first contacts 11 spaced apart along a first direction, a first gap 15 for inserting a positive electrode plug-in 51 of a charging plug 5 is provided between each two adjacent first contacts 11, and at least one of each two adjacent first contacts 11 is a first conductive contact 12, so that the positive electrode plug-in 51 inserted into any first gap 15 can be in conductive contact with the first conductive contact 12. The negative electrode plug-in portion 2 includes at least three second contacts 21 spaced apart along a first direction, a second gap 25 for inserting a negative electrode plug-in 52 of a charging plug 5 is provided between each two adjacent second contacts 21, and at least one of each two adjacent second contacts 21 is a second conductive contact 22, so that the negative electrode plug-in 52 inserted into any second gap 25 can be in conductive contact with the second conductive contact 22.

[0045] In the above-mentioned charging socket 10, the positive electrode plug-in portion 1 and the negative electrode plug-in portion 2 can be used to be connected to the positive electrode and the negative electrode of the battery or power source respectively. Figure 2 and Figure 8 As shown, the positive electrode plug part 1 includes at least three first contact pieces 11 spaced apart along the first direction, and a first gap 15 is provided between each two adjacent first contact pieces 11, that is, the positive electrode plug part 1 may have at least two first gaps 15 spaced apart along the first direction, and any of the at least two first gaps 15 can be inserted into the positive electrode plug part 51. In the process of docking the positive electrode plug part 1 and the positive electrode plug part 51, the positive electrode plug part 51 is inserted into any of the at least two first gaps 15, and the conductive connection between the positive electrode plug part 1 and the positive electrode plug part 51 can be achieved. Therefore, the positive electrode plug part 1 and the positive electrode plug part 51 can achieve a wider range of positions in the first direction in which they can be connected, thereby reducing the position accuracy requirements of the docking process.

[0046] Similarly, it can be known that the negative electrode plug part 2 can have at least two second gaps 25 spaced apart along the first direction, and any of the at least two second gaps 25 can be inserted into the negative electrode plug part 52. During the docking process between the negative electrode plug part 2 and the negative electrode plug part 52, the negative electrode plug part 52 can be inserted into any of the at least two second gaps 25, and the conductive connection between the negative electrode plug part 2 and the negative electrode plug part 52 can be achieved. Therefore, the negative electrode plug part 2 and the negative electrode plug part 52 can achieve a wider range of positions in the first direction where they can be connected, thereby reducing the position accuracy requirements of the docking process.

[0047] The charging socket 10 provided in the embodiment of the present disclosure can be applied to any electronic device. In the implementation scenario where the charging socket 10 is applied to a mobile electronic device, for example, the charging socket 10 is applied to a robot 100, such as Figure 1 and Figure 6 As shown, the robot 100 will automatically move to the vicinity of the robot charging device 200 (such as a charging seat or a charging pile) when charging, and the charging socket 10 on the robot 100 moves toward the charging plug 5 on the robot charging device 200. Since the above-mentioned charging socket 10 has low position accuracy requirements for the docking process between the positive pole plug part 1 and the positive pole plug connector 51, and low position accuracy requirements for the docking process between the negative pole plug part 2 and the negative pole plug connector 52, even if a position error occurs in the first direction when the robot 100 and the robot charging device 200 are docked, the charging plug 5 can be inserted into the charging socket 10 to achieve a conductive connection between the robot 100 and the robot charging device 200, thereby ensuring the successful charging of the robot 100.

[0048] Through the above technical scheme, the positive electrode connector 51 is inserted into any one of the at least two first gaps 15, and the conductive connection between the positive electrode connector 1 and the positive electrode connector 51 can be achieved. The positive electrode connector 1 and the positive electrode connector 51 can achieve a wider range of positions for connection in the first direction. The negative electrode connector 52 is inserted into any one of the at least two second gaps 25, and the conductive connection between the negative electrode connector 2 and the negative electrode connector 52 can be achieved. The negative electrode connector 2 and the negative electrode connector 52 can achieve a wider range of positions for connection in the first direction, thereby reducing the position accuracy requirements for the docking of the charging socket 10 and the charging plug 5, which is more conducive to achieving the charging connection.

[0049] It should be noted that in the above-mentioned charging socket 10, the positive electrode plug part 1 and the negative electrode plug part 2 can be arranged at intervals along the first direction, or the positive electrode plug part 1 and the negative electrode plug part 2 can also be arranged at intervals along the second direction perpendicular to the first direction, or the positive electrode plug part 1 and the negative electrode plug part 2 can be arranged separately at different positions. The present disclosure does not make specific restrictions on this. In the embodiment of the charging socket 10 applied to the robot 100, as Figure 1 As shown, optionally, the positive electrode plug part 1 and the negative electrode plug part 2 can be arranged at intervals along the first direction, where the first direction can be the height direction of the robot 100. The above-mentioned charging socket 10 can be applied not only to the robot 100, but also to any fixed electronic device, for example, it can be set on a charging pile or a charging seat, or the charging socket 10 can also be set on any movable electronic device, for example, it can be set on a mobile terminal, a wearable device or an aircraft. The embodiment of the present disclosure does not limit the specific application scenario of the charging socket 10.

[0050] In the above embodiment, the first conductive contact piece 12 refers to a contact piece that can contact with the positive electrode connector 51 and exchange current, and the second conductive contact piece 22 refers to a contact piece that can contact with the negative electrode connector 52 and exchange current. The first conductive contact piece 12 and the second conductive contact piece 22 can both be made of metal materials (such as copper, aluminum, tin, lead, nickel or titanium). The aforementioned at least one of every two adjacent first contact pieces 11 is a first conductive contact piece 12 means that one of every two adjacent first contact pieces 11 can be a first conductive contact piece 12, or both first contact pieces 11 can be first conductive contact pieces 12.

[0051] As an exemplary embodiment, optionally, two adjacent first contact pieces 11 can both be first conductive contact pieces 12, that is, the positive electrode connector 51 can achieve conductive contact with any one of the first contact pieces 11, and realize current exchange between the positive electrode connector 51 and the positive electrode connector 1. In this embodiment, when the positive electrode connector 51 is inserted into the first gap 15, the two first conductive contact pieces 12 can both contact the positive electrode connector 51, which has a large conductive contact area, can pass a large current, and has good conductive properties. Correspondingly, optionally, two adjacent second contact pieces 21 can also both be second conductive contact pieces 22, that is, the negative electrode connector 52 can achieve conductive contact with any one of the second contact pieces 21, and realize current exchange between the negative electrode connector 52 and the negative electrode connector 2.

[0052] As another exemplary embodiment, Figure 3 As shown, optionally, one of every two adjacent first contacts 11 can be a first conductive contact 12, and the other of every two adjacent first contacts 11 can be a first insulating contact 13. In this embodiment, when the positive electrode connector 51 is inserted into the first gap 15, one side of the positive electrode connector 51 contacts the first conductive contact 12 to achieve conductivity, and the other side of the positive electrode connector 51 contacts the first insulating contact 13. The first insulating sheet can separate the positive electrode connector 51 and the other first contacts 11 from each other, thereby ensuring the safety of the electrical connection between the positive electrode connector 51 and the first conductive contact 12. In addition, compared with the embodiment in which all the first contacts 11 are the first conductive contacts 12, the first insulating contact 13 does not need to be connected to the battery or power supply by arranging a line, and one of every two adjacent first contacts 11 is the first insulating contact 13, which can simplify the circuit complexity and reduce the hardware cost.

[0053] Correspondingly, optionally, one of every two adjacent second contact pieces 21 is a second conductive contact piece 22 , and the other of every two adjacent second contact pieces 21 is a second insulating contact piece 23 .

[0054] In the above embodiments, the first insulating contact piece 13 and the second insulating contact piece 23 can be made of any insulating material (such as nylon or epoxy resin, etc.), or the first insulating contact piece 13 and the second insulating contact piece 23 can also be coated or wrapped with an insulating surface layer. The present disclosure does not limit the specific structure and composition of the first insulating contact piece 13 and the second insulating contact piece 23.

[0055] In order to ensure that the positive electrode connector 51 can be stably plugged into the first gap 15, optionally, the distance between each two adjacent first contact pieces 11 in the first direction is set to be smaller than the size of the positive electrode connector 51 in the first direction, so that each two adjacent first contact pieces 11 can be interference-fitted with the positive electrode connector 51. Since the distance between the two adjacent first contact pieces 11 in the first direction is set to be smaller than the size of the positive electrode connector 51 in the first direction, when the positive electrode connector 51 is plugged into the first gap 15, under the support of the positive electrode connector 51, the two adjacent first contact pieces 11 produce a certain elastic deformation so as to be clamped in the positive electrode connector 51. Therefore, the two first contact pieces 11 can be closely attached to the positive electrode connector 51 under the action of their own elastic force, thereby ensuring that the positive electrode connector 51 can be stably plugged into the first gap 15.

[0056] In order to ensure that the negative electrode connector 52 can be stably plugged into the second gap 25, optionally, the distance between each two adjacent second contact pieces 21 in the first direction is set to be smaller than the size of the negative electrode connector 52 in the first direction, so that each two adjacent second contact pieces 21 can have an interference fit with the negative electrode connector 52, and the two second contact pieces 21 can fit tightly to the negative electrode connector 52 under the action of their own elastic force, thereby ensuring that the negative electrode connector 52 can be stably plugged into the second gap 25.

[0057] The positive electrode plug part 1 and the negative electrode plug part 2 can be fixed to the charging socket 10, that is, the positive electrode plug part 1 and the negative electrode plug part 2 are fixed relative to the charging socket 10 and do not move. Alternatively, the positive electrode plug part 1 and the negative electrode plug part 2 can be movably connected to the charging socket 10. Figures 2 to 4 As shown in FIG. 1 , as an exemplary embodiment, optionally, the charging socket 10 may include a fixed shaft 3 extending along a first direction, and the positive electrode plug-in portion 1 and the negative electrode plug-in portion 2 may be movably connected to the fixed shaft 3 along the first direction. Figure 4 and Figure 8As shown, during the docking process between the positive electrode connector 1 and the positive electrode connector 51, if the positive electrode connector 51 and the first gap 15 are arranged in a staggered manner, under the action of the force of the positive electrode connector 51 when abutting, the positive electrode connector 1 and the negative electrode connector 2 can move along the first direction, so that the positive electrode connector 51 and the first gap 15 can face each other and achieve plugging, and similarly, the negative electrode connector 52 and the second gap 25 can face each other and achieve plugging. It can be seen that the positive electrode connector 1 and the negative electrode connector 2 can be movably connected to the fixed shaft 3 along the first direction, which can further reduce the position accuracy requirements of the docking process.

[0058] In the above embodiment, optionally, the charging socket 10 further includes a first elastic member 41 and a second elastic member 42 spaced apart along the first direction, and the positive electrode plug part 1 and the negative electrode plug part 2 are clamped between the first elastic member 41 and the second elastic member 42. The first elastic member 41 and the second elastic member 42 can provide a restoring elastic force for the positive electrode plug part 1 and the negative electrode plug part 2, and the positive electrode plug part 1 and the negative electrode plug part 2 move along the first direction under the action of the force of the positive electrode plug part 51 and the negative electrode plug part 52. When the force of the positive electrode plug part 51 and the negative electrode plug part 52 is cancelled, that is, the positive electrode plug part 51 and the negative electrode plug part 52 are away from the positive electrode plug part 1 and the negative electrode plug part 2, the positive electrode plug part 1 and the negative electrode plug part 2 can return to the initial position under the action of the elastic force of the first elastic member 41 and the second elastic member 42, so as to facilitate the subsequent docking.

[0059] In the positive electrode plug-in portion 1, each first contact piece 11 can be fixedly connected to each other, or, as Figure 3 and Figure 4 As shown, optionally, each first contact piece 11 can be movably arranged on the fixed shaft 3, and a first gap retainer 43 is arranged between each two adjacent first contact pieces 11. When the positive electrode plug part 1 is inserted into or away from the first gap 15, the first gap retainer 43 can provide a distance of the first gap 15 to maintain stability, thereby facilitating subsequent docking and improving the stability of the charging socket.

[0060] In the negative electrode plug-in portion 2 , each second contact piece 21 may be fixedly connected to each other, or each second contact piece 21 may be movably disposed through the fixed shaft 3 , and a first gap retaining member 43 is disposed between each two adjacent second contact pieces 21 .

[0061] Optionally, a second gap retainer 44 is provided between the positive electrode plug-in portion 1 and the negative electrode plug-in portion 2. The second gap retainer 44 can keep the positional relationship between the positive electrode plug-in portion 1 and the negative electrode plug-in portion 2 stable.

[0062] As an exemplary embodiment, optionally, the first gap retainer 43 and / or the second gap retainer 44 may be an elastic support member. For example, the first gap retainer 43 and / or the second gap retainer 44 may be a coil spring, an elastic block or a spring sheet.

[0063] As another exemplary embodiment, optionally, the first gap retainer 43 and / or the second gap retainer 44 may be a rigid support member. For example, the first gap retainer 43 and / or the second gap retainer 44 may be a structure made of nylon or plastic.

[0064] In order to facilitate the insertion of the positive electrode connector 51 into the first gap 15, Figure 4 As shown, optionally, one end of the first gap 15 for inserting the positive connector 51 is the first open end 16, and a first guide portion 14 is formed at the end of each first contact piece 11 close to the first open end 16. Along the direction extending from the first open end 16 into the first gap 15, the distance between the first guide portions 14 of each adjacent two first contact pieces 11 in the first direction gradually decreases.

[0065] In order to facilitate the insertion of the negative electrode connector 52 into the second gap 25, Figure 4 As shown, optionally, one end of the second gap 25 for inserting the negative electrode connector 52 is a second open end 26, and a second guide portion 24 is formed at the end of each second contact piece 21 close to the second open end 26. Along the direction extending from the second open end 26 into the second gap 25, the distance between the second guide portions 24 of each adjacent two second contact pieces 21 in the first direction gradually decreases.

[0066] A second aspect of the present disclosure provides a charging connector assembly 6, including a charging plug 5 and the above-mentioned charging socket 10, the charging plug 5 including a positive connector 51 and a negative connector 52, the positive connector 51 is used to be inserted into any first gap 15 of the charging socket 10, and the negative connector 52 is used to be inserted into any second gap 25 of the charging socket 10.

[0067] In the above-mentioned charging connector assembly 6, the charging plug 5 and the charging socket 10 can be respectively set on different electronic devices. For example, one of the charging socket 10 and the charging socket 10 can be set on the robot 100, and the other can be set on the robot charging device 200. The charging plug 5 is plugged into the charging socket 10 to realize current exchange, thereby realizing the charging of the robot 100 by the robot charging device 200.

[0068] Through the above-mentioned charging connector assembly 6, the positive pole connector 51 is inserted into any one of the at least two first gaps 15, and the conductive connection between the positive pole connector 1 and the positive pole connector 51 can be achieved. The positive pole connector 1 and the positive pole connector 51 can achieve a wider range of positions for connection in the first direction. The negative pole connector 52 is inserted into any one of the at least two second gaps 25, and the conductive connection between the negative pole connector 2 and the negative pole connector 52 can be achieved. The negative pole connector 2 and the negative pole connector 52 can achieve a wider range of positions for connection in the first direction, thereby reducing the position accuracy requirements for docking the charging socket 10 and the charging plug 5, which is more conducive to achieving the charging connection.

[0069] In order to ensure that the positive connector 51 can be inserted into the first gap 15 and the negative connector 52 can be inserted into the second gap 25, optionally, the size of the positive connector 51 in the second direction perpendicular to the first direction is smaller than the size of the first gap 15 in the second direction, and the size of the negative connector 52 in the second direction perpendicular to the first direction is smaller than the size of the second gap 25 in the second direction.

[0070] In the above embodiment, optionally, the size of the first gap 15 in the second direction is greater than or equal to 1.5 times the size of the positive electrode connector 51 in the second direction, and the size of the second gap 25 in the second direction is greater than or equal to 1.5 times the size of the negative electrode connector 52 in the second direction.

[0071] The positive electrode connector 51 and the negative electrode connector 52 of the charging plug 5 are easily corroded or rusted when exposed to the air for a long time, resulting in damage to the function of the charging plug 5. Optionally, as an exemplary embodiment, the charging plug 5 may include a main body 53, a protective cover 54 and a third elastic member 55, the positive electrode connector 51 and the negative electrode connector 52 both extend outward from the main body 53 along a third direction perpendicular to the first direction, and the protective cover 54 is movably connected to the main body 53 along the third direction and has a first position and a second position.

[0072] like Figure 5 and Figure 6 As shown, in the first position, at least part of the protective cover 54 protrudes from the main body 53 along the third direction and covers the outer sides of the positive electrode connector 51 and the negative electrode connector 52. Figure 7 and Figure 8 As shown, in the second position, the protective cover 54 moves along the third direction toward the inside of the main body 53 to at least partially expose the positive connector 51 and the negative connector 52, and the third elastic member 55 is connected between the main body 53 and the protective cover 54 and is used to provide an elastic force to keep the protective cover 54 in the first position.

[0073] As an exemplary embodiment, optionally, one of the charging plug 5 and the charging socket 10 described above may be used to be set on the robot 100 , and the other of the charging plug 5 and the charging socket 10 may be used to be set on the robot charging device 200 .

[0074] The third aspect of the present disclosure further provides a robot 100 , comprising the above-mentioned charging socket 10 .

[0075] In the above-mentioned robot 100, the robot 100 will automatically move to the vicinity of the robot charging device 200 when charging, and the charging socket 10 on the robot 100 moves toward the charging plug 5 on the robot charging device 200. Since the position accuracy requirements of the docking process between the positive pole plug part 1 and the positive pole connector 51 are low, and the position accuracy requirements of the docking process between the negative pole plug part 2 and the negative pole connector 52 are low, even if a position error in the first direction occurs when the robot 100 and the robot charging device 200 are docked, the charging plug 5 can be inserted into the charging socket 10 to achieve conductive connection, thereby ensuring the charging performance of the robot 100.

[0076] The robot 100 mentioned above may be a sweeping robot, a freight robot, a food delivery robot or an inspection robot, etc. The present disclosure does not limit the specific application scenarios and functional structures of the robot 100.
