Description

Technical Field

[0001] This application relates to the field of vehicle charging technology, and more particularly to a charging gun and charging device. Background Technology

[0002] With the improvement of charging power for new energy vehicles, the technological iteration and performance upgrade of charging guns have become the focus of industry attention. The charging gun has terminals for connecting cables and charging interfaces on the vehicle, so that the charging gun can charge the vehicle. During the assembly of the charging gun, a cable management frame is required to limit and fix the terminals. After the terminals are fixed on the cable management frame, the cable management frame and the terminals are connected to the gun head together. The connection between the cable management frame and the gun head is generally fixed with self-tapping screws. However, due to the small space inside the gun head, the terminals and cables inside the charging gun can hinder the operator from tightening the screws, affecting the production assembly efficiency. Utility Model Content

[0003] This application provides a charging gun and a charging device, which can improve the assembly efficiency of the charging gun.

[0004] A charging gun includes a gun head, a cable management frame, and a gun housing. The gun head and the gun housing are connected and form an accommodating space. The cable management frame is disposed in the accommodating space and is snapped into the gun head by a snap-fit ​​structure. The cable management frame is used to install terminals.

[0005] By incorporating a snap-fit ​​structure between the charging head and the cable management frame, replacing the screws used in related technologies to connect the cable management frame and the charging head, the connection between the charging head and the cable management frame is made easier. This solves the problem of difficult installation and operation between the cable management frame and the charging head due to the limited space between the charging head and the charging housing. Installation and disassembly are more convenient, improving the production and assembly efficiency of the charging gun, while reducing screw materials and lowering material management costs.

[0006] Optionally, the accommodating space includes a first accommodating space located at the gun head and a second accommodating space located at the gun casing. The locking structure includes a slot provided on the side wall of the first accommodating space and a locking block provided on the cable management rack, with the locking block locked in the slot.

[0007] The installation, disassembly, replacement, and maintenance of the charging gun are made more convenient by providing a slot on the plug part of the gun head and a locking block on the outer wall of the cable management rack.

[0008] Optionally, the snap-fit ​​structure also includes a connecting plate, the first end of which is connected to the cable management rack, and the snap-fit ​​block is located at the second end of the connecting plate, with the first and second ends positioned opposite each other.

[0009] By setting a connecting plate with elastic deformation function, the card block can slide on the inner wall of the insertion part until the card block is inserted into the card slot, which makes it easier to connect the card block and the card slot.

[0010] Optionally, there can be multiple card slots, with the card slots spaced apart around the cable management frame; or there can be multiple card blocks, with each card block being locked into one card slot.

[0011] The distribution of the clips and slots is relatively even, which makes the force between the cable management frame and the gun head more balanced, and makes the installation between the cable management frame and the gun head more secure and less likely to come off.

[0012] Optionally, the gun head and the gun housing are detachable, which facilitates the replacement and maintenance of the gun housing, gun head, and cable management rack.

[0013] Optionally, the end of the gun head facing the gun housing is provided with a plug-in part, which is inserted into the second accommodating space. A slot is provided on the plug-in part, and the gun head and the gun housing can be plugged into each other to facilitate the installation and removal of the gun head and the gun housing.

[0014] Optionally, the gun casing is provided with a stopper, which is located within the accommodating space and is used to abut against the end of the cable management rack away from the gun head.

[0015] It can apply a certain clamping force to the cable management frame in the direction of insertion between the cable management frame and the charging head, so as to prevent the cable management frame from shifting in the direction of insertion between the cable management frame and the charging head if the slot and the locking block become loose, thereby strengthening the overall strength of the charging gun.

[0016] Optionally, the accommodating space includes a first accommodating space located at the gun head and a second accommodating space located at the gun casing. A sliding structure is provided between the first accommodating space and the cable management rack. The sliding structure is used to guide the cable management rack to move into the first accommodating space, and the sliding structure is also used to prevent the cable management rack from rotating about an axis parallel to the insertion direction of the gun head.

[0017] By setting a sliding structure with anti-rotation function between the cable management rack and the gun head, it is ensured that when the cable management rack is inserted into the gun head, it can only slide along the axis parallel to the insertion direction of the gun head, and the two will not rotate. By setting the positional relationship between the sliding mechanism and the locking structure, it is ensured that when the cable management rack and the gun head can slide, the positions of the locking block and the locking slot will also correspond to each other, which has a foolproof function and makes the installation process more convenient, saving time and effort.

[0018] Optionally, the sliding structure includes a first positioning surface disposed on the side wall of the first accommodating space and a second positioning surface disposed on the cable management rack, wherein the first positioning surface is in contact with the second positioning surface.

[0019] By setting a first positioning surface and a second positioning surface structure on the gun casing and the cable management frame respectively, good orientation and foolproof function can be achieved. The first and second positioning surfaces are evenly stressed, providing more stable support and thus achieving a better guiding effect. The cable management frame can only slide relative to the gun casing after the first and second positioning surfaces are aligned, and it can only slide in one direction. The positions of the guide structure, the locking block, and the locking slot are pre-set. As long as the cable management frame slides in that direction, the locking block can be smoothly inserted into the locking slot, making installation more convenient.

[0020] Optionally, both the first and second positioning surfaces can be curved surfaces.

[0021] By designing the sliding structure as an arc surface, and setting arc surfaces that can slide relative to each other on the outer wall of the cable management rack and the inner wall of the plug-in part, the arc surface slides more smoothly and reduces the risk of jamming during the sliding process.

[0022] A charging device includes a charger and the aforementioned charging gun. The charging gun is connected to the charger. The charger can be a charging pile, a charging station, or a power supply device for a portable charger, etc. The charging gun is connected to the charger to enable charging of vehicles.

[0023] The charging device provided in this application includes the charging gun in the above embodiments, and therefore can achieve the same technical effect and solve the same technical problem. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0038] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0039] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" are defined relative to the orientation of the components shown in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation of the components in the accompanying drawings.

[0040] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, an electrical connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0041] The charging gun is an important component of the charging system for new energy vehicles. Its main function is to transfer electrical energy to the vehicle's battery. The charging gun in the charging equipment connects to the vehicle to achieve charging. In order to improve the efficiency and stability of power transmission, the internal cables of the charging gun are divided into multiple strands such as neutral wire, protective ground wire, and signal wire. These multiple strands are connected one by one to different terminals, including live wire terminal, neutral wire terminal, protective ground wire terminal, and signal wire terminal. Each terminal has its own function. The vehicle has a terminal slot, and the terminal slot contains a conductor that is electrically connected to the terminal. The terminal is inserted into the terminal slot to enable the charging gun to charge the vehicle.

[0042] To manage and protect the cables and terminals inside the charging gun, ensure its normal operation, and extend its service life, a cable management rack is often installed inside the charging gun. The cable management rack neatly secures and organizes the cables inside the charging gun, preventing damage from movement or twisting during charging. Especially during charging, cables frequently move and bend; the cable management rack reduces friction and wear between cables, extending their lifespan. It also reduces interference between cables, ensuring stable current transmission, thereby improving charging efficiency and safety. Furthermore, the cable management rack makes the cable layout clearly visible, allowing maintenance personnel to quickly locate problems during troubleshooting and repair, reducing maintenance time and costs.

[0043] In related technologies, cable management racks and charging gun heads are mostly assembled and fixed using self-tapping screws. The terminals and multiple strands of cable bundled together inside the charging gun take up a lot of space. Therefore, the terminals and cables restrict the operator's operating space for tightening screws, making assembly time-consuming, labor-intensive, and inefficient. At the same time, the self-tapping screws used to install the cable management racks and charging gun heads cannot be shared with other screws on the charging gun heads, which increases additional material management costs.

[0044] In other related technologies, there is a solution that integrates the cable management frame and the gun head into a single structure. However, since the cable management frame and the gun head are a single structure, it is not easy to process the terminal positioning grooves inside for precise positioning of the terminals. Therefore, the terminals are difficult to be firmly fixed, the installation process of the gun head is complicated, and under normal circumstances, due to the lack of axial fastening force between the gun head and the gun housing, the gun head and the gun housing are prone to detachment during long-term use. It is also difficult to achieve a high level of dust and water resistance, which is not conducive to improving the protection level of the gun head. In addition, the integrated structure will also increase the weight of the gun head.

[0045] The rapid development of new energy vehicles has placed higher demands on the overall performance of charging guns, especially for liquid-cooled supercharging guns, whose demand is increasing rapidly year by year. Due to the complex assembly process, the production volume of liquid-cooled supercharging guns is relatively low.

[0046] To address the aforementioned technical issues, this application provides a charging device, including a charger and a charging gun. The charger can be a home charging station installed in a parking space, a public charging station installed in a public place, a large-scale charging station, a power supply device for use with portable chargers, etc. The charger generally includes a rectifier and a charging management system. The rectifier converts AC power into DC power, and the charging management system is responsible for monitoring the battery's charge and status and adjusting the charging current according to the vehicle's needs. When the vehicle is connected to the charger, communication is established between the charger and the vehicle, and information such as battery type and maximum charging power is transmitted through a communication protocol. The charger adjusts according to the received information and inputs appropriate DC power into the battery through the charging gun connected to the charger to charge the vehicle.

[0047] Please see Figures 1-2 The charging gun includes a charging head 100, a cable management rack 200, and a charging housing 300. The charging housing 300 has a handle 330 for easy gripping. The charging head 100 and the charging housing 300 are detachable for easy maintenance and replacement. The charging head 100 and the charging housing 300 form a receiving space 500, within which the cable management rack 200 is installed. The cable management rack 200 has terminal positioning slots 220 for fixing terminals 400. (See also...) Figure 3 The terminal positioning groove 220 can be used to install the terminal 400. The terminal positioning groove 220 is generally semi-circular and has a certain degree of elasticity. The terminal 400 can be locked in the terminal positioning groove 220, which can ensure the positioning and fixation of the terminal 400. The multi-strand cable in the charging gun is connected to the terminal 400. The cable management frame 200 is locked to the gun head 100 through a snap-fit ​​structure.

[0048] By setting a snap-fit ​​structure between the charging head 100 and the cable management frame 200, instead of using screws to connect the cable management frame 200 and the charging head 100 in related technologies, the installation and disassembly of the charging head 100 and the cable management frame 200 are made easier. This solves the problem of difficult screw installation due to the narrow space between the charging head 100 and the charging housing 300, improves the production and assembly efficiency of the charging gun, and reduces screw materials, thereby reducing material management costs.

[0049] See Figures 4-5In some embodiments, the snap-fit ​​structure includes a slot 111, a block 211, and a connecting plate 210. The slot 111 snaps into the block 211. The connecting plate 210 has a certain elasticity. The first end of the connecting plate 210 is connected to the cable management frame 200. The block 211 is disposed at the second end of the connecting plate 210. The first end and the second end of the connecting plate 210 are disposed opposite to each other. The slot 111 is disposed on the head 100, and its position can be adaptively selected according to the position of the block 211. During the insertion of the cable management frame 200 into the head 100, before the block 211 is snapped into the slot 111, the block 211 slides in contact with the inner wall of the insertion part 110. At this time, the connecting plate 210 is in an elastic deformation state. After the block 211 is snapped into the slot 111, the connecting plate 210 returns to its initial state. The cable management frame 200 has a hollowed-out groove 240 in the deformation direction of the connecting plate 210. See [reference needed] Figure 3 The hollow groove 240 can provide clearance when the connecting plate 210 undergoes elastic deformation.

[0050] By setting a connecting plate 210 with elastic deformation function, the card block 211 can slide on the inner wall of the insertion part 110 until the card block 211 is inserted into the card slot 111, which makes it easier to connect the card block 211 and the card slot 111.

[0051] Please see Figure 1 In some embodiments, the accommodating space 500 includes a first accommodating space 510 located on the gun head 100 and a second accommodating space 520 located on the gun housing 300. A plug-in portion 110 is provided at the end of the gun head 100 facing the gun housing 300. The plug-in portion 110 is located near the cable management frame 200 and has a certain space inside. This space is the first accommodating space 510. A portion of the cable management frame 200 can be inserted into the first accommodating space 510, and the other portion of the cable management frame 200 is located in the second accommodating space 520. The slot 111 is a rectangular slot and is located on the side wall of the first accommodating space 510, i.e., the slot 111 is located in the plug-in portion 110. On the outer wall of the cable management rack 200, the slot 111 is located on the outer wall of the insertion part 110, which is more convenient for it to engage smoothly with the block 211 on the cable management rack 200 compared to other positions on the gun housing 300. The block 211 is located on the outer wall of the cable management rack 200. After the cable management rack 200 is inserted into the first accommodating space 510, the block 211 on the outer wall of the cable management rack 200 can be locked in the slot 111, thereby limiting and fixing the cable management rack 200. The operation is simpler and more convenient, and the installation process is smoother. After the slot 111 and the block 211 are connected, the outer wall of the cable management rack 200 can be limited and fixed to prevent the cable management rack 200 from shifting within the first accommodating space 510, and the limiting effect is better.

[0052] By providing a slot 111 on the plug part 110 on the gun head 100 and a locking block 211 on the outer wall of the cable management rack 200, the installation, disassembly, replacement and maintenance of the charging gun are made more convenient.

[0053] In the above implementation, there are multiple card slots 111, and the multiple card slots 111 are spaced apart around the cable management frame 200, see [reference]. Figures 5-6 There are multiple locking blocks 211. The positions of the locking blocks 211 on the cable management frame 200 and the locking slots 111 on the gun head 100 are set one-to-one, so that each locking block 211 is locked in a corresponding locking slot 111. The locking blocks 211 and the locking slots 111 cooperate with each other to realize the positioning of the cable management frame 200, eliminating the tedious operation of tightening screws. For example, there are four locking slots 111 and four locking blocks 211, and the four locking slots 111 are symmetrically distributed on the gun head 100. The angle between two adjacent locking slots 111 and the geometric center line of the gun head 100 can be set to be greater than 30°. The specific angle is not limited in this application. It is ensured that the locking slots 111 and locking blocks 211 are evenly distributed, so that the force between the cable management frame 200 and the gun head 100 is more balanced, and the installation between the cable management frame 200 and the gun head 100 is more secure and not easy to detach.

[0054] Please see Figure 7 In some embodiments, the insertion portion 110 on the head 100 has a platform surface 112, and at least two slots 111 are provided on the platform surface 112. The platform surface 112 can be used as a reference. When two locking blocks 211 on the cable management rack 200 corresponding to the two slots 111 on the platform surface 112 are simultaneously engaged into the two slots 111, see [reference needed]. Figure 4 Other card blocks 211 will also snap into their corresponding card slots 111 at the same time. Therefore, the platform surface 112 has a foolproof function, which makes the charging gun install more quickly.

[0055] In some embodiments, the detachable connection between the gun head 100 and the gun housing 300 facilitates the replacement and maintenance of structures such as the gun housing 300, the gun head 100, and the cable management rack 200.

[0056] Please see Figures 8-9Because the gun casing 300 and the gun head 100 need to withstand a large tensile force, they can be connected by bolts. The blocking member 130 has a gun head screw hole 131, and the end face of the gun casing 300 near the gun head 100 also has a corresponding gun casing screw hole 320. By screwing screws into the gun head screw holes 131 on the blocking member 130 and the gun casing screw holes 320 on the gun casing 300, a secure connection between the gun casing 300 and the gun head 100 is achieved. A pin connection can also be used between them. A positioning pin hole is provided on the side wall of the insertion part 110, which avoids the setting position of the slot 111. A corresponding positioning pin hole is also provided on the gun housing 300. The pin can be interference-fitted with the positioning pin hole on the gun housing 300 and the gun head 100. After the gun housing 300 is inserted into the insertion part 110 of the gun head 100, the pin can be squeezed into the positioning pin hole on the gun housing 300 and the gun head 100 by external force, thereby making a firm connection between the gun housing 300 and the gun head 100.

[0057] In some embodiments, the insertion portion 110 of the end of the gun head 100 facing the gun housing 300 is inserted into the second accommodating space 520, that is, the gun housing 300 is sleeved on the outside of the insertion portion 110. The gun head 100 and the gun housing 300 can be inserted and removed from each other to facilitate the installation and removal of the gun head 100 and the gun housing 300. Since the slot 111 is provided on the outer wall of the insertion portion 110, the locking block 211 and the slot 111 are covered by the gun housing 300, preventing the locking block 211 and the slot 111 from being exposed outside the gun housing 300.

[0058] Please see Figure 9 The gun head 100 is also provided with a blocking member 130, which is located at the end of the insertion part 110 near the gun head 100. The blocking member 130 is a stepped structure protruding from the outside of the gun housing 300. When the gun head 100 and the gun housing 300 are installed, one end of the gun housing 300 is fitted with one end of the blocking member 130. The blocking member 130 is mainly used to limit the distance of the insertion part 110 into the gun housing 300. After this distance is preset, a stop member 310 is provided inside the gun housing 300. See Figures 10-11 The abutment 310 can just abut against the end of the cable management rack 200 that is far from the gun head 100.

[0059] In some embodiments, multiple abutment members 310 may be provided on the gun casing 300. In this embodiment, considering the force balance of the cable management rack 200, four abutment members 310 are provided. The abutment members 310 can be integrally formed with the gun casing 300. The abutment members 310 are located within the second accommodating space 520 and extend inward from the inner wall of the gun casing 300. Their shape can be block-shaped or strip-shaped, etc. The abutment members 310 are used to abut against the end of the cable management rack 200 away from the gun head 100, and can provide support to the cable management rack 200 in the insertion direction of the cable management rack 200 and the gun head 100. A certain clamping force is applied to prevent the cable management frame 200 from shifting in the direction of insertion between the cable management frame 200 and the gun head 100 if the slot 111 and the block 211 become loose, thereby strengthening the overall strength of the charging gun. At the same time, since the cable passes through the gun housing 300 and connects to the terminal 400, when the cable load exceeds the bearing capacity of the block 211 and the slot 111, the abutment 310 can abut against the cable management frame 200 to prevent the cable management frame 200 from moving away from the gun housing 300 and to prevent the terminal 400 on the cable management frame 200 from retracting into the gun housing 300.

[0060] In some embodiments, a sliding structure is provided between the first accommodating space 510 of the gun head 100 and the cable management rack 200. The sliding structure can serve as a guide rail between the cable management rack 200 and the gun housing 300, providing a good guiding effect and guiding the cable management rack 200 to move into the first accommodating space 510, making the installation process more convenient. In addition, if the cable management rack 200 can rotate relative to the gun head 100, it will be difficult to quickly snap the locking block 211 on the cable management rack 200 into the locking slot 111 on the plug-in part 110, and the installation will be time-consuming and laborious. Therefore, the sliding structure is also used to prevent the cable management rack 200 from rotating about an axis parallel to the plug-in direction of the gun head 100.

[0061] By setting a sliding structure with anti-rotation function between the cable management frame 200 and the gun head 100, it is ensured that when the cable management frame 200 is inserted into the gun head 100, it can only slide along the axis parallel to the insertion direction of the gun head 100, and the two will not rotate. By setting the positional relationship between the sliding mechanism and the locking structure, it is ensured that when the cable management frame 200 and the gun head 100 can slide, the positions of the locking block 211 and the locking slot 111 will also correspond to each other, which has a foolproof function and makes the installation process more convenient, saving time and effort.

[0062] When assembling the charging gun, first install the terminal 400 into the corresponding terminal positioning slot 220 of the cable management frame 200 for initial fixation. Then, push the cable management frame 200 with the terminal 400 into the gun head 100 until the locking block 211 of the cable management frame 200 engages with the locking slot 111 on the plug-in part 110. After the gun head 100 and the cable management frame 200 are assembled together through the sliding structure, push the gun head 100 with the cable management frame 200 into the gun housing 300 in parallel. Finally, use screws to connect and fix the gun housing 300 and the gun head 100.

[0063] Please see Figure 12 In some embodiments, the sliding structure includes a first positioning surface 120 disposed on the sidewall of the first accommodating space 510 and a second positioning surface 230 disposed on the cable management rack 200, see [link to relevant documentation]. Figure 4 The first positioning surface 120 is in contact with the second positioning surface 230. The shape and position of the second positioning surface 230 correspond to the shape and position of the first positioning surface 120. The first positioning surface 120 and the second positioning surface 230 can slide relative to each other. The number of the first positioning surface 120 and the second positioning surface 230 can be set to multiple, for example, four of each.

[0064] The outer shape of the first positioning surface 120 can be a groove structure, and the shape of the groove structure can be semi-circular, rectangular, trapezoidal, etc. The outer shape of the second positioning surface 230 can be a rib structure. The shapes of the rib structure and the groove structure are adapted to each other, and the rib structure and the groove structure can slide and cooperate with each other. It can be understood that the outer shape of the first positioning surface 120 can also be a rib structure, and the outer shape of the second positioning surface 230 can be a groove structure. This embodiment does not limit this. Since the outer wall of the rib structure and the groove structure fits more tightly, the groove structure, as a guide rail, can guide and limit the outer wall of the rib structure, so that the guidance between the cable management frame 200 and the gun head 100 is better.

[0065] By setting a first positioning surface 120 and a second positioning surface 230 on the gun housing 300 and the cable management rack 200 respectively, good orientation and foolproof function can be achieved. The first positioning surface 120 and the second positioning surface 230 are subjected to balanced forces, and the support is more stable, thereby achieving a better guiding effect. The cable management rack 200 can only slide relative to the gun housing 300 after the first positioning surface 120 and the second positioning surface 230 are aligned, and can only slide in one direction. The positions of the guide structure, the locking block 211 and the locking slot 111 are preset. As long as the cable management rack 200 slides in this direction, the locking block 211 can be smoothly locked into the locking slot 111, making the installation more convenient.

[0066] In some embodiments, both the first positioning surface 120 and the second positioning surface 230 are arc surfaces. In this embodiment, the first positioning surface 120 is an arc surface protruding inward from the inner wall of the insertion part 110, and the second positioning surface 230 is an arc surface on the outer wall of the cable management rack 200. During the process of installing the cable management rack 200 into the gun housing 300, the arc surface of the inner wall of the insertion part 110 can slide and cooperate with the arc surface of the outer wall of the cable management rack 200 as a guide rail. The shapes and positions of the two are set in a one-to-one correspondence, which can realize the functions of preventing relative rotation between the cable management rack 200 and the gun head 100, guiding and limiting, and preventing mistake.

[0067] By designing the sliding structure as an arc surface, and providing arc surfaces that can slide relative to each other on the outer wall of the cable management rack 200 and the inner wall of the plug-in part 110, the arc surface slides more smoothly, reducing the risk of jamming during the sliding process.

[0068] The above description is merely a specific implementation of the embodiments of this application, but the protection scope of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the protection scope of this application. Therefore, the protection scope of this application should be determined by the protection scope of the claims.
