Detailed Implementation

[0028] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention.

It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] As mentioned in the background section, in the prior art, one type of charging gun can only be used with one type of robotic arm, resulting in poor versatility. Therefore, this application provides a novel charging gun gripping device that can adapt to different charging gun shapes and different models or brands of robotic arms. The charging gun gripping device of this application will be described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 5 As shown in the embodiment of this application, a charging gun gripping device is provided, which includes: a robotic arm 10, an electromagnetic suction component 20, and a clamping component 30.

[0033] Specifically, the electromagnetic attraction component 20 is connected to the robotic arm 10. The electromagnetic attraction component 20 has a first state in which it generates magnetic attraction force when energized and a second state in which it eliminates magnetic attraction force when de-energized. The clamping component 30 includes a connecting part 31 and a locking part 32. The connecting part 31 and the locking part 32 are fixedly connected. The locking part 32 is used to fix the charging gun 40. The electromagnetic attraction component 20 has a first position in which it uses magnetic attraction force to attract and fix the connecting part 31 to the robotic arm 10 and a second position in which it is separated from the connecting part 31.

[0034] In this application, the electromagnetic suction component 20 is connected to the robotic arm 10. The robotic arm 10 can supply power to the electromagnetic suction component 20 to put it into a first state where it is energized and generates electromagnetic attraction, and the robotic arm 10 can also stop supplying power to the electromagnetic suction component 20 to put it into a second state where it is de-energized and eliminates the magnetic attraction. It is understood that the electromagnetic suction component 20 has the characteristics of being magnetic when energized and demagnetized when de-energized, replacing the complex connection structure of traditional mechanical buckles, cylinder drives, etc., and realizing the rapid docking or separation of the clamping component 30 and the robotic arm 10.

[0035] Furthermore, in this application, the clamping component 30 includes a connecting portion 31 and a locking portion 32. The connecting portion 31 and the locking portion 32 are fixedly connected, and the locking portion 32 is used to fix the charging gun 40. The electromagnetic attraction component 20 has a first position where the connecting portion 31 is attracted and fixed to the robotic arm 10 by magnetic attraction, and a second position where it is separated from the connecting portion 31. In some application scenarios, the magnetic attraction of the electromagnetic attraction can firmly fix the clamping component 30 to the robotic arm 10, preventing the clamping component 30 from shaking during the movement of the robotic arm 10. At the same time, the locking portion 32 directly locks the charging gun 40 through a mechanical structure, preventing it from falling off even when subjected to the weight of the charging gun 40 itself (or slight external impact). In addition, the electromagnetic attraction component 20 and the clamping component 30 are magnetically and detachably connected, improving the maintenance convenience and compatibility of the charging gun gripping device. Specifically, the charging gun gripping device is compatible with multiple models of charging guns 40. It can design a special locking part 32 to suit different brands and specifications of charging guns 40. Only the clamping part 30 needs to be replaced. There is no need to replace core components such as the robotic arm 10 or the electromagnetic suction part 20. There is no need to make special gripping devices for different charging guns 40, which improves the versatility of the device and reduces the universal cost of the equipment.

[0036] In other words, in this application, by setting up an electromagnetic attraction component 20 and a clamping component 30, the electromagnetic attraction component 20 uses magnetic attraction to attract and fix the connecting part 31 to the robotic arm 10 or separate it from the connecting part 31. This charging gun gripping device can be compatible with multiple models of charging guns 40 and multiple models of robotic arms 10, thus improving the versatility of the device.

[0037] like Figure 4 As shown, the electromagnetic suction component 20 includes a mounting portion 21. Specifically, the mounting portion 21 includes a first mounting end 211 and a second mounting end 212 connected to the first mounting end 211. The robotic arm 10 is connected to the first mounting end 211, and the electromagnetic suction component 20 is disposed on the second mounting end 212. In some application scenarios, the robotic arm 10 needs to move the electromagnetic suction component 20, the clamping component 30, and the charging gun 40 together, thus requiring high load-bearing capacity and stability of the connection structure. In actual production, the first mounting end 211 is designed as a high-strength connection structure. For example, the first mounting end 211 can be set as a flange 50 with multiple bolt holes (e.g., Figures 2 to 4 (As shown). In other embodiments of this application, the first mounting end 211 can also be configured as a thickened metal interface, etc., as long as it is a variation under the concept of this application, it is within the protection scope of this application. In addition, the second mounting end 212 can be designed as a high-precision flat mounting surface, and its size matches the electromagnetic suction component 20 to ensure that the electromagnetic suction component 20 can be completely attached and fixed without gaps.

[0038] Furthermore, in this application, a predetermined distance is maintained between the first mounting end 211 and the second mounting end 212. This arrangement avoids interference between the robotic arm 10 and the electromagnetic suction device. If the electromagnetic suction device 20 is directly mounted on the end of the robotic arm 10, the joints of the robotic arm 10 (such as a rotary axis or telescopic arm) may block the suction direction of the electromagnetic suction device 20 during movement (for example, the robotic arm 10 body may obstruct the docking path of the clamping component 30). By extending or offsetting the second mounting end 212, the electromagnetic suction device 20 can be offset from the robotic arm 10 body, ensuring that its suction surface can be directly aligned with the connection portion 31 of the clamping component 30 without obstruction. In addition, the split-end arrangement simplifies the maintenance and replacement process and reduces downtime.

[0039] like Figure 2 As shown, a mounting plate 22 is provided on the second mounting end 212, and the electromagnetic attraction component 20 also includes an electromagnet 23, which is mounted on the mounting plate 22. The electromagnet 23 is electrically connected to a power source and has a first state where it generates magnetic attraction when energized and a second state where it eliminates magnetic attraction when de-energized. This configuration provides mounting support for the electromagnet 23, improving its installation accuracy and ensuring uniform magnetic attraction and adsorption stability. Simultaneously, the mounting plate 22 protects the second mounting end 212, reducing wear and tear on the mounting part 21 and maintenance costs. Furthermore, in actual operation, the electromagnet 23 may need to be adjusted in model according to the weight of the charging gun 40 and the size of the connection part 31 of the clamping component 30 (e.g., low-power models are adapted to lightweight AC guns, and high-power models are adapted to heavy-duty DC guns). Since the mounting interfaces of different models of electromagnet 23 may differ, the mounting plate 22 can serve as a standardized intermediate interface, thereby reducing the adaptation costs for various models of electromagnet 23.

[0040] like Figures 1 to 4 As shown, the electromagnet 23 includes at least two pieces, which are arranged at a predetermined distance from each other on the mounting plate 22 along the height direction of the mounting plate 22. Exemplarily, there can be two, three, or more electromagnets 23; the figures in this application show the case of two electromagnets 23. In this application, the arrangement of multiple electromagnets 23 at intervals along the height direction of the mounting plate 22 can disperse the adsorption force and improve adsorption stability. Specifically, the concentrated magnetic force of a single electromagnet 23 can cause the contact point of the connection part 31 to be subjected to strong pressure for a long time, which may lead to metal fatigue or indentation (especially for thin connection parts 31); while multiple electromagnets 23 disperse the total magnetic force, reducing the force per unit area and extending the service life of the connection part 31. If one of the electromagnets 23 suddenly malfunctions during the gripping process of the robotic arm 10, the single electromagnet 23 will directly lose its adsorption force, causing the clamping component 30 to fall off, which may damage the charging gun 40 or cause a safety accident. Multiple electromagnets 23 arranged at intervals can form redundant protection.

[0041] Furthermore, switching a single electromagnet 23 on and off can cause the magnetic force to be instantly present or absent, potentially resulting in an impact during attraction (a hard collision between the connecting part 31 and the electromagnet 23) or a slight drop in the gripping component 30 during release due to the rapid disappearance of the magnetic force. Multiple electromagnets 23 spaced apart can optimize this process by optimizing the magnetic force gradient and controlling the timing. For example, when the robotic arm 10 supplies power to the electromagnets 23, the control system can supply and de-energize the electromagnets 23 in different sequences according to attraction and release, making the grasping and releasing actions smoother and protecting delicate components such as the charging gun 40's interface.

[0042] like Figure 2 and Figure 3 As shown, the electromagnetic suction component 20 is provided with a positioning part 24, and the connecting part 31 is provided with a positioning mating part 311 that cooperates with the positioning part 24. For example, the positioning part 24 and the positioning mating part 311 can be in the form of a boss and a groove, a positioning post and a positioning hole, a guide slope and an adapter surface, etc. This application provides a positioning part 24 on the electromagnetic suction component 20 and a positioning mating part 311 on the connecting part 31 that cooperates with the positioning part 24. This configuration forces precise alignment and avoids the risk of misalignment during electromagnetic suction. If relying solely on the magnetic attraction force of the electromagnet 23, misalignment between the electromagnet 23 and the connecting part 31 may occur due to positioning errors of the robotic arm 10, slight impurities on the surface of the connecting part 31, or uneven distribution of magnetic attraction force (e.g., the connecting part 31 is tilted to the left / right, or tilted). Furthermore, during the process of grasping and moving the charging gun 40, the robotic arm 10 will face the effects of inertial forces (such as the impact force during starting and braking) and gravity (the weight of the charging gun 40 itself). If fixed solely by magnetic attraction, the connecting part 31 may rotate around or slide along the adsorption surface, causing the locking part 32 of the clamping component 30 to deviate from the gripping position of the charging gun 40. Simultaneously, the cooperation of the positioning part 24 and the positioning mating part 311 reduces the positioning accuracy requirements of the robotic arm 10, thereby improving the efficiency of the electromagnetic adsorption operation. It also prevents the electromagnet 23 from colliding with the edge of the connecting part 31 during adsorption, thus avoiding wear on the surface of the electromagnet 23 and deformation of the connecting part 31, and extending the service life of the components.

[0043] Furthermore, one of the positioning part 24 and the positioning mating part 311 is a positioning post, and the other is a positioning mating hole that mates with the positioning post. In this application, Figure 2 and Figure 4 The illustration shows a case where the positioning part 24 is a positioning pin and the positioning mating part 311 is a positioning hole. The positioning pin and positioning hole have a simple structure, are easy to manufacture, and offer controllable precision and low cost. Furthermore, the replacement cost is low after the positioning pin and positioning hole wear down during long-term use.

[0044] like Figure 2 and Figure 4As shown, the positioning posts include at least two posts, and the positioning mating holes include at least two holes, with each positioning post and hole corresponding to the other. For example, there can be two, three, or more positioning posts, and two, three, or more positioning holes. The specific number can be adapted to actual production conditions, as long as the positioning posts and holes are matched one-to-one. Compared to a single positioning post and a single positioning hole, at least two positioning posts and at least two positioning holes prevent the connecting part 31 from rotating the charging gun 40, thereby improving docking accuracy. Furthermore, multiple positioning posts can disperse radial stress, preventing wear or breakage caused by stress concentration in a single set of posts and holes. Simultaneously, the combination of multiple posts and holes forms multi-point support, enhancing the anti-tilting and anti-vibration capabilities of the positioning structure.

[0045] Furthermore, the connecting part 31 includes any one of a magnet, a steel plate, or an iron plate. Specifically, in this application, the connecting part 31 can be made of any ferromagnetic material. When the electromagnet 23 is energized, it can directly respond to the magnetic attraction of the electromagnet 23 and be compatible with the automated logic of energized adsorption and de-energized separation; it also needs to have basic structural strength to support the weight of the charging gun 40. In this application, the connecting part 31 is preferably a steel plate or an iron plate. The steel plate is only magnetized when the electromagnet 23 is energized and has no residual magnetism after de-energization. The connecting part 31 can immediately separate from the electromagnet 23 without residual magnetism causing adsorption residue (e.g., when the robotic arm 10 releases, the steel plate will not stick to the electromagnet 23), which is suitable for high-precision release scenarios. At the same time, the cost of steel plates is lower than that of magnets. Iron plates have the lowest cost, high cost-effectiveness, high magnetic permeability, and fast adsorption response.

[0046] Furthermore, in this application, the clamping component 30 also includes a support structure 33, with the connecting portion 31 protruding from the surface of the support structure 33, and the support structure 33 having positioning and mating holes corresponding to those on the connecting portion 31. The support structure 33 serves as a rigid foundation, enhancing the overall load-bearing capacity of the clamping component 30. The connecting portion 31 needs to directly engage (attract and position) with the electromagnet 23 and positioning portion 24 of the electromagnetic attraction component 20. The protrusion of the connecting portion 31 from the surface of the support structure 33 ensures that the electromagnet 23 only contacts the connecting portion 31 and is not obstructed or separated by other areas of the support structure 33. If the support structure 33 is flush with the connecting portion 31, the unevenness of the support structure 33's surface may result in the electromagnet 23 not being firmly attracted. Furthermore, the protrusion of the connecting portion 31 from the surface of the support structure 33 provides space for positioning operations. Specifically, when the positioning pin is inserted into the positioning hole, the protrusion height of the connecting part 31 can prevent the surface of the support structure 33 from directly contacting the mounting plate 22 of the electromagnetic suction component 20, providing sufficient space for the insertion and removal of the positioning pin. If the positioning hole were directly located on the connecting part 31, the hole wall strength might be insufficient due to the limited thickness of the connecting part 31. The positioning hole connects to the support structure 33, which can improve positioning accuracy and durability.

[0047] Furthermore, in this application, the support structure 33 can be designed as an L-shaped, U-shaped, or other irregular shape according to the shape and weight distribution of the charging gun 40, adapting to the spatial posture of the charging gun 40 during gripping and optimizing the flexibility of the gripping operation. In other words, the support structure 33 not only solves the problems of insufficient load-bearing capacity and low positioning accuracy of a single component, but also improves the assembly efficiency and maintenance convenience of the clamping component 30, ultimately ensuring the stability, accuracy, and durability of the gripping process of the charging gun 40.

[0048] like Figures 1 to 5 As shown, the locking part 32 includes a first locking member 321 and a second locking member 322 connected to the first locking member 321. The first locking member 321 has a locking groove facing away from the connecting part 31, and the second locking member 322 has a locking ring facing away from the connecting part 31. It is understood that the shapes of different parts of the charging gun 40 (handle, interface end, shell) vary greatly, and a single locking structure (such as only a locking groove or only a locking ring) cannot adapt to all gripping needs. In this application, two locking members work together to adapt to the shapes of various charging guns 40, improving the versatility of the charging gun gripping device. Specifically, the first locking member 321 has a locking groove to adapt to long strip / edge-shaped gripping points. The locking groove, such as U-shaped or V-shaped, can quickly engage. The interface end of the charging gun 40, the positioning post at the bottom of the handle, and other parts are mostly cylindrical or have annular grooves. The locking ring (closed circular / annular structure) can wrap around these parts in a circumferential manner. This design covers the gripping references (edges, cylinders, annular grooves, etc.) of mainstream charging guns 40 on the market, eliminating the need to design separate clamping components 30 for different models of charging guns 40, significantly improving versatility. The locking groove and locking ring provide bidirectional limiting, enhancing gripping stability. The synergistic effect of the bidirectional limiting ensures the stable posture of the charging gun 40, preventing loosening or displacement. Simultaneously, the locking groove and locking ring improve gripping accuracy, ensuring a high success rate for charging docking.

[0049] Specifically, in this application, the working principle of the charging gun gripping device is as follows: When the robotic arm 10 carrying the electromagnetic suction component 20 docks with the clamping component 30 of the charging gun 40, the robotic arm 10 energizes the electromagnet 23, causing the electromagnetic suction component 20 to firmly adhere to the clamping component 30. Simultaneously, the electromagnet 23 and the connecting part 31 form a mechanical drag, achieving the purpose of the robotic arm 10 gripping the charging gun 40. When it is necessary to release the charging gun 40, the electromagnet 23 is de-energized, and the robotic arm 10 carrying the electromagnetic suction component 20 separates from the connecting part 31, exiting the docking with the clamping component 30.

[0050] In many current automatic charging scenarios, the charging gun 40 is specially designed to match the gripping or fixing of the robotic arm 10, making it incompatible with other types of robotic arms 10 and reducing the interchangeability and versatility of similar products. Furthermore, this type of charging gun 40, with its special gripping structure, is relatively small and lacks high-power charging capabilities, limiting its application scenarios. However, the electromagnetic suction component 20 of the charging gun gripping device provided in this application can be installed on the end of most conventional robotic arms 10 on the market, and the clamping component 30 can be installed on most charging guns 40 on the market, with power ranging from 60kW to 1500kW, thus improving the versatility of the charging gun gripping device.

[0051] See you again Figures 1 to 5 As shown, this application also provides a charging station that includes the aforementioned charging gun gripping device. Therefore, all the technical effects of including the charging gun gripping device in the above embodiments are already described in detail above and will not be repeated here.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0053] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
