Description
Technical Field
[0001] This utility model relates to the field of charging equipment technology, and specifically to a floating charging terminal. Background Technology
[0002] As a key electrical connection component, floating charging terminals are widely used in electric vehicle automatic charging devices, mobile power supply interfaces for industrial equipment, and other scenarios. In these applications, charging terminals need to be frequently plugged and unplugged and are subjected to vibration and shock from vehicle or equipment operation for a long time. Therefore, the reliability of their connection, their ability to adapt to assembly errors and operating vibrations, and their long-term stability are directly related to the continuity and safety of the power supply of the entire charging system or equipment, and are an important part of improving the automation level of equipment and user experience.
[0003] In existing technical solutions, charging terminals (i.e., terminal bodies) are usually directly fixed on the charging module or mounting base through a rigid connection. Although this rigid installation method is simple in structure, it has obvious limitations in practical applications. First, it cannot effectively compensate for assembly errors in the spacing and depth of the pin holes caused by manufacturing and installation. It is also difficult to adapt to the continuous small relative displacement between the terminal and the mating end caused by vibration during equipment operation. It cannot ensure a stable electrical connection, effectively absorb and resolve multi-dimensional assembly deviations and continuous vibrations, and avoid contact instability, component damage or connection breakage caused by rigid connection. Vibration is directly transmitted, affecting the reliability of the connection. Moreover, the charging terminals are easily damaged by stress concentration caused by vibration. Utility Model Content
[0004] The purpose of this invention is to provide a floating charging terminal that can compensate for assembly errors in the first and second directions caused by manufacturing and installation, facilitate the installation of the charging terminal, and also help absorb vibrations during use, reducing damage to the charging terminal.
[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a floating charging terminal, including a terminal body mounted on a charging module; The terminal body is connected to the charging module via a limiting mechanism; The limiting mechanism includes a fixing member, a limiting member, and a locking nut. One end of the fixing member is fixedly connected to the terminal body, and the other end is provided with a guide groove along a first direction. The limiting member passes through the guide groove along a second direction and slides within the guide groove along the first direction. A damping is provided between the limiting member and the fixing member. The charging module is slidably connected to the portion of the limiting member that extends out of the guide groove along the second direction through an opening clearance hole. The surface of the locking nut is threadedly connected to the portion of the limiting member that extends out of the clearance hole through an opening threaded hole, and one of its surfaces abuts against the charging module.
[0006] Optionally, the fixing member includes a fixing ear, the guide groove is formed at one end of the fixing ear, and there are two fixing ears, which are respectively fixedly connected to both ends of the terminal body.
[0007] Optionally, the number of limiting members corresponds to the number of fixing ears, and the inner wall of the clearance hole is spaced apart from the outer surface of the limiting member.
[0008] Optionally, the limiting member includes a limiting part, a first limiting segment, and a second limiting segment arranged sequentially along the second direction. The limiting part at least partially abuts against the surface of the fixing ear away from the charging module. The first limiting segment is located in the guide groove and is spaced apart from the inner wall of the guide groove. One end of the first limiting segment opposite to the limiting part abuts against the terminal body. The second limiting segment is fixedly connected to one end of the first limiting segment opposite to the limiting part and is threadedly connected to the locking nut through the clearance hole.
[0009] Optionally, the limiting part includes a limiting head, a limiting sleeve, and a limiting spring. One end of the limiting head is fixedly connected to one end of the first limiting segment away from the second limiting segment. One end of the limiting sleeve is slidably connected to the limiting head through a groove. The bottom of the groove of the limiting sleeve is slidably connected to the outer surface of the first limiting segment through a through hole. The limiting spring is disposed between the bottom of the groove of the limiting sleeve and the limiting head, and is sleeved on the outside of the first limiting segment.
[0010] Optionally, the other end of the limiting sleeve abuts against the fixing ear, and the surfaces of the limiting sleeve and the fixing ear are provided with transverse lines distributed sequentially along the first direction.
[0011] Optionally, the terminal body is provided with multiple connection ports.
[0012] This utility model provides a floating charging terminal, which has the following advantages: This floating charging terminal is connected to a limiting member and a guide groove. The limiting member can slide in the guide groove along a first direction, and simultaneously has space to reciprocate in the guide groove along a second direction. Relatively speaking, the fixed member with the guide groove can slide on the limiting member along the first and second directions. This enables adaptive compensation of assembly errors and insertion / removal deviations of the terminal body in the first and second directions during assembly. During operation, small relative displacements caused by vehicle or equipment vibrations are accommodated by the travel of the guide groove and the corresponding direction, avoiding connection breakage caused by hard connection and preventing damage caused by vibration transmission. At the same time, the damping function absorbs and dissipates micro-vibration energy, preventing vibration from damaging the terminal body. This provides vibration protection for the terminal body, ensuring long-term stable insertion / removal and conductivity reliability. During maintenance, only the locking nut needs to be loosened to remove the limiting member and terminal body for replacement or repair, improving maintenance convenience. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0016] Please see Figures 1 to 4This utility model provides a technical solution: a charging terminal, specifically applied to scenarios such as mobile power supply interfaces for vehicle or industrial equipment. During installation, it can adaptively compensate for assembly errors and insertion / removal deviations in the first and second directions, avoiding excessively large installation openings or errors in the spacing between the two fixing holes that would make installation inconvenient. Specifically, it is a floating charging terminal.
[0017] Please see Figures 1 to 4 The present invention provides a technical solution: a floating charging terminal, including a terminal body 10 installed on a charging module 50; The terminal body 10 is connected to the charging module 50 via the limiting mechanism 20; The limiting mechanism 20 includes a fixing member 21, a limiting member 22, and a locking nut 23. One end of the fixing member 21 is fixedly connected to the terminal body 10, and the other end is provided with a guide groove 211 along the first direction. The limiting member 22 passes through the guide groove 211 along the second direction and slides in the guide groove 211 along the first direction. A damping is provided between the limiting member 22 and the fixing member 21. The charging module 50 is slidably connected to the part of the limiting member 22 that passes through the guide groove 211 through the opening clearance hole 51 along the second direction. The surface of the locking nut 23 is threadedly connected to the part of the limiting member 22 that passes through the clearance hole 51 through the opening threaded hole, and one of its surfaces abuts against the charging module 50. Damping is not a structural name, but a known technology. That is, there is a damping force between the limiting member 22 and the fixing member 21. When the limiting member 22 and the fixing member 21 want to move in the first direction, the damping force needs to be overcome. The damping force is a flexible force, which is a known technology. The cooperation between the guide groove 211 and the limiting member 22 provides the terminal with a floating degree of freedom in the first direction; while the cooperation between the clearance hole 51 and the limiting member 22 provides a floating degree of freedom in the second direction. The combination of these two degrees of freedom makes the terminal body 10 no longer a fixed point during docking, but a floating head that can move slightly in the plane. It can automatically compensate for dimensional tolerances, assembly errors, and slight deformations during operation between the charging device and the receiving device in the first and second directions. The presence of damping optimizes the floating, specifically, transforming free sliding into... Controlled, buffered micro-movements effectively absorb vibration and impact energy from the outside, avoiding hard collisions and wear, improving connection stability and component lifespan. Locking nut 23 provides adjustability and ultimate protection for this floating system, ensuring that the limiting member 22 will not loosen during vibration, maintaining the integrity of the structure, and allowing the preload of the floating group to be adjusted according to actual needs. Ultimately, this series of designs work together to ensure that the charging interface maintains a tight and reliable electrical connection under various operating conditions, while minimizing mechanical stress damage to the terminals themselves and the charging module 50.
[0018] In this embodiment, as a preferred option, the fixing member 21 includes a fixing ear 212, and a guide groove 211 is formed at one end of the fixing ear 212. There are two fixing ears 212, and the two fixing ears 212 are respectively fixedly connected to the two ends of the terminal body 10. The guide groove 211 formed on each fixing ear 212 together defines the trajectory axis of the floating of the terminal body 10. The core function of this symmetrical distribution is that it decomposes and transmits the offset force in any direction to the two support points located on the same axis, thereby ensuring that the terminal body 10 always maintains pure linear translation when floating, effectively preventing jamming, warping or rotation that may occur due to single-point support, and realizing floating stability and connection reliability. When the docking device applies pressure from the side or angle, the force will be evenly distributed to the two solid fixing ears 212, avoiding stress concentration, thereby improving mechanical life and durability.
[0019] In this embodiment, as a preferred option, the number of limiting members 22 corresponds to the number of fixing ears 212. The inner wall of the guide groove 211 is spaced apart from the outer surface of the limiting member 22. The number of limiting members 22 corresponds one-to-one with the number of fixing ears 212. Each fixing ear 212 is supported and guided by an independent limiting member 22. The one-to-one pairing constitutes a distributed and balanced load-bearing structure. Furthermore, the limiting member 22 is spaced apart from the inner wall of the guide groove 211, thereby forming another degree of freedom, further improving the floating direction range, thereby effectively improving the floating adjustment range, improving the ease of installation, and avoiding the inconvenience of installation due to the skewed opening of the mounting terminal body 10. At this time, the first direction is the vertical direction (i.e. the direction of gravity), and the central axis of the opening of the mounting terminal body 10 is inclined relative to the first direction. The through hole that cooperates with the limiting member 22 coincides with the central axis of the opening along the first direction. The terminal body 10 can still be installed into the opening without affecting the installation of the limiting member 22. The first direction is not a direction. For example, the first direction is a straight line from left to right. Both left and right are the first direction.
[0020] In this embodiment, as a preferred option, the limiting member 22 includes a limiting part 221, a first limiting segment 222, and a second limiting segment 223 arranged sequentially along the second direction. The limiting part 221 at least partially abuts against the surface of the fixing ear 212 away from the charging module 50 to generate damping. The first limiting segment 222 is located in the guide groove 211 and is spaced apart from the inner wall of the guide groove 211. One end of the first limiting segment 222 away from the limiting part 221 abuts against the terminal body 10. The second limiting segment 223 is fixedly connected to the end of the first limiting segment 222 away from the limiting part 221 and is threadedly connected to the locking nut 23 through the clearance hole 51. The first limiting segment 222 is used to slide in the guide groove 211 and also serves to guide and cooperate with the guide groove 211 to limit the range of motion. The second limiting segment 223 is used to be threadedly connected to the locking nut 23 to form a limiting in the second direction.
[0021] In this embodiment, as a preferred option, the limiting part 221 includes a limiting head 2211, a limiting sleeve 2212, and a limiting spring 2213. One end of the limiting head 2211 is fixedly connected to one end of the first limiting segment 222 away from the second limiting segment 223. One end of the limiting sleeve 2212 is slidably connected to the limiting head 2211 through a groove. The bottom of the groove of the limiting sleeve 2212 is slidably connected to the outer surface of the first limiting segment 222 through a through hole. The limiting spring 2213 is disposed between the bottom of the groove of the limiting sleeve 2212 and the limiting head 2211, and is sleeved on the outside of the first limiting segment 222. The function of 11 is to limit one end in the second direction. At the same time, the limiting head 2211 has an opening for cooperating with a screwdriver, which serves as a support. When the locking nut 23 is tightened, the limiting sleeve 2212 is fitted on the outer surface of the limiting head 2211 and can slide on the limiting head 2211 in the second direction. Through the action of the limiting spring 2213, when relatively extended, an elastic force is generated to push the limiting sleeve 2212 against the fixing ear 212 to generate frictional damping force. Furthermore, the elastic force of the limiting spring 2213 is sufficient to support the completion of the above working steps and purposes.
[0022] In this embodiment, as a preferred option, the other end of the limiting sleeve 2212 abuts against the fixing ear 212. The surfaces of the limiting sleeve 2212 and the fixing ear 212 are provided with horizontal lines distributed sequentially along the first direction. The purpose of the horizontal lines is to increase friction and improve the damping effect.
[0023] In this embodiment, as a preferred solution, the terminal body 10 is provided with multiple connection ports, which are used to connect with external electrical appliances. This is a well-known technology and will not be described in detail here.
[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
