[0030] In some embodiments, please refer to Figure 1 The present application provides a bushing type limiter 100 for constraining the position of a charging cable. The limiter 100 includes: a supporting component 10, a connecting component 20 and a hanging component 30. The supporting component 10 is used for winding the charging cable; the connecting component 20 is connected to the supporting component 10, and the hanging component 30 is connected to the connecting component 20 for installation on the object to be installed.

[0031] The above-mentioned bushing-type limiter 100 for constraining the position of the charging cable can wrap the charging cable around the supporting assembly 10 during the charging process, so that it can be stored and supported on the supporting assembly 10; then, the supporting assembly 10 carrying the charging cable is connected to the suspension assembly 30 through the connecting assembly 20; finally, the suspension assembly 30 is installed on the object to be installed, so that the charging cable is suspended on the object to be installed, avoiding it from being distributed on the ground in the charging state and being easily crushed by the wheels of other vehicles. With such a design, the limiter 100 can effectively contain the charging cable, avoid the risk of being crushed by other vehicles in the charging state, and improve the safety of charging.

[0032] It should be noted that the structure on the supporting assembly 10 for winding the charging cable bears most of the weight of the charging cable. Therefore, when selecting the material for the supporting assembly 10, a structure with greater structural strength should be selected, such as metal materials such as aluminum alloy and stainless steel. Of course, plastics such as engineering plastics can also be used. To facilitate the winding of the charging cable, the structure of the supporting assembly 10 can have a variety of designs, such as but not limited to a wheel-shaped structure, a rod-shaped structure, etc.

[0033] After the charging cable is wound, there are many ways to connect the supporting assembly 10 and the connecting assembly 20, such as but not limited to bolt connection, clamping connection, pin connection, binding connection, etc. The structure of the connecting assembly 20 can be designed as a chain structure, a rope structure, etc. At the same time, there are many materials, as long as they can meet the suspension of the supporting assembly 10.

[0034] In addition, the suspension component 30 is connected to the connection component 20, so that the support component 10 carrying the charging cable is suspended. There are also many ways to connect the suspension component 30 and the connection component 20, such as but not limited to bolt connection, clamping, pin connection, binding, hanging, etc. In the charging state, the object to be installed can have a variety of designs, such as but not limited to the box of the charging pile 200, the column of the underground warehouse, the width of the vehicle, etc.

[0035] Specifically, the object to be installed is the width of a vehicle.

[0036] For further information, please refer to Figure 2 The supporting assembly 10 includes a first supporting member 11, a second supporting member 12, and a supporting component 14 connected between the first supporting member 11 and the second supporting member 12. The first supporting member 11 and the second supporting member 12 are both connected to the connecting assembly 20, and the supporting component 14 is used for winding the charging cable. It can be seen that the charging cable is installed on the first supporting member 11 and the second supporting member 12, so that the supporting force of the charging cable is more stable, which is conducive to ensuring the stable suspension of the charging cable, thereby further improving the safety of charging.

[0037] It should be noted that the first support member 11 and the second support member 12 are respectively located at the two ends of the supporting member 14, and can form a triangular structure with the suspension assembly 30 to improve the stability of the suspension. At the same time, the first support member 11 and the second support member 12 can be designed as a block structure or a columnar structure. In some examples, the first support member 11 and the second support member 12 are both columnar structures, and the length directions of the first support member 11 and the second support member 12 are respectively perpendicular to the length direction of the supporting member 14.

[0038] There are many ways to connect the first support member 11 and the second support member 12 to the supporting member 14, such as: clamping, bolting, pinning, welding, riveting, integral molding, etc. Among them, integral molding can be but not limited to extrusion, casting, cutting, 3D printing, etc.

[0039] It should also be noted that the supporting member 14 can be extended and retracted along its length direction; or it can be a fixed structure and cannot be adjusted. When the supporting member 14 can be extended and retracted along its length direction, the extension length of the supporting member 14 can be adjusted according to the length of the charging cable, so that the charging cable can be better wound around the supporting member 14.

[0040] For further information, please refer to Figure 2 and Figure 3 The supporting member 14 includes a first supporting portion 141 and a second supporting portion 142. The first supporting portion 141 is sleeved on the outer periphery of the second supporting portion 142, and the relative position between the first supporting portion 141 and the second supporting portion 142 in the length direction of the supporting member 14 is adjustable. It can be seen that the supporting member 14 can be telescopically adjusted along its own length direction. When the length of the charging cable is relatively short, more of the second supporting portion 142 can be inserted into the first supporting portion 141 to shorten the overall length of the supporting member 14; when the length of the charging cable is relatively long, the second supporting portion 142 can be partially pulled out of the first supporting portion 141 to lengthen the overall length of the supporting member 14. Such a design is conducive to improving the flexibility of the limiter 100, thereby improving the performance of the limiter 100.

[0041] It should be noted that there are many ways to implement the telescopic adjustment between the first supporting part 141 and the second supporting part 142 along the length direction, such as: the first supporting part 141 is sleeved outside the second supporting part 142 and connected by threads; or, the first supporting part 141 and the second supporting part 142 are provided with multiple pin holes at intervals along the length direction, and the pins are inserted into different pin holes to achieve length adjustment, etc.

[0042] In some embodiments, please refer to Figure 4 and Figure 5The hanging component 30 includes a hanging component 32, a shell 31 having an outlet 311, and a first stopper 33 provided on the shell 31. The hanging component 32 is accommodated in the shell 31, and at least a part of the hanging component 32 can be extended from the outlet 311. The part of the hanging component 32 extending outside the outlet 311 is connected to the first stopper 33 to form a hanging cavity 34 for hanging on the object to be installed. The connecting component 20 is connected to the shell 31. It can be seen that during the hanging process, the hanging component 32 can be pulled out from the outlet 311, so that one end of the hanging component 32 is connected to the first stopper 33, so that an annular hanging cavity 34 is formed on the hanging component 32. At this time, the hanging component 30 is quickly hung on the object to be installed through the hanging cavity 34, which is conducive to improving the convenience of installation.

[0043] It should be noted that the hanging member 32 may have a certain elastic or flexible structure, for example, it may be a steel wire, a steel sheet, a nylon wire, etc. The connection between the hanging member 32 and the first position-limiting member 33 may be binding, clamping, bolting, etc. At the same time, the first position-limiting member 33 may be arranged on the housing 31 in a manner that is not limited to bolting, clamping, riveting, welding, pinning, integrated molding, etc.

[0044] In addition, the length of the hanging member 32 extending out of the housing 31 can be changed, so that it can be effectively mounted on the periphery of the object to be installed, such as the width of a vehicle, so as to adapt to different shapes and sizes of vehicle widths.

[0045] For further information, please refer to Figure 6 The suspension assembly 30 further includes a spring 39, which is disposed in the housing 31, and the hanging member 32 is connected to and wound on the spring 39. It can be seen that when the suspension assembly 30 needs to be hung on the object to be installed, the hanging member is pulled out from the outlet 311 so that it can be connected with the first stopper 33 and form an annular hanging cavity 34. When the suspension assembly 30 does not need to be hung on the object to be installed, the hanging member 32 is stopped from being pulled, and the spring 39 is elastically restored to rewind the hanging member 32 around the outer periphery of the spiral spring 39 so that it is effectively stored in the housing 31.

[0046] In some embodiments, please refer to Figure 4 The suspension assembly 30 further includes a second stopper 35, which is disposed on the housing 31 and is used to abut against the portion of the hanging member 32 located at the outlet 311. In this way, the second stopper 35 abuts against the hanging member 32, so that the length of the hanging member 32 extending out of the outlet 311 remains unchanged, thereby improving the stability of the suspension.

[0047] For some examples, see Figure 4 and Figure 6The hanging member 32 is connected to and wound on the clockwork spring 39. At this time, the second limit member 35 is used to abut against the hanging member 32, so as to prevent the hanging member 32 from automatically retracting into the housing 31 under the torsion of the clockwork spring 39, thereby ensuring the suspension effect of the suspension assembly 30.

[0048] In order to facilitate the installation of the clockwork spring 39 in the housing 31 , a mounting shaft 3837 may be provided in the housing 31 , and the clockwork spring 39 is sleeved on the mounting shaft 3837 .

[0049] Among them, the second limit member 35 can be designed as a sliding structure, and the second limit member 35 can be moved on the shell 31 by pushing the second limit member 35, and one end of the second limit member 35 can be abutted against the hanging member 32; or, the second limit member 35 can also be designed as a bolt or screw structure, and one end of the second limit member 35 can be abutted against the hanging member 32 through rotation adjustment.

[0050] In addition, there are various designs for the position of the second limiter 35 on the housing 31 , for example, the second limiter 35 may be on the side of the outlet 311 away from the first limiter 33 ; or, the second limiter 35 may be located between the outlet 311 and the first limiter 33 and be arranged adjacent to the outlet 311 .

[0051] In some embodiments, please refer to Figure 4 The suspension assembly 30 further includes a connecting protrusion 36, which is disposed on the housing 31 and is used to connect with the connecting assembly 20. Thus, the connecting protrusion 36 facilitates the connection between the connecting assembly 20 and the suspension assembly 30, which is beneficial to improving the assembly efficiency of the stopper 100.

[0052] The connection method between the connection assembly 20 and the connection protrusion 36 may be, but is not limited to, bolt connection, clamping, riveting, pin connection, binding, etc.

[0053] In some embodiments, please refer to Figure 7 The connecting component 20 includes a hook member 22 and a hanging rope 21. The two ends of the hanging rope 21 are connected to the supporting component 10 at intervals. The hook member 22 is provided on the hanging rope 21 and is used to connect with the hanging component 30. It can be seen that after the charging cable is wound around the supporting component 10, the two ends of the hanging rope 21 can be connected to the supporting component 10 at intervals, and the hanging rope 21 can be hung on the hanging component 30 through the hook member 22. In this way, the introduction of the hook member 22 and the hanging rope 21 facilitates the stable suspension of the charging cable.

[0054] It should be noted that when the supporting assembly 10 includes a first supporting member 11, a second supporting member 12, and a supporting member 14 connected between the first supporting member 11 and the second supporting member 12, one end of the hanging rope 21 is connected to the first supporting member 11, and the other end is connected to the second supporting member 12. To facilitate the connection of the hanging rope 21 with the first supporting member 11 and the second supporting member 12, the ends of the first supporting member 11 and the second supporting member 12 are provided with a fixing protrusion 13, and one end of the hanging rope 21 is connected to the fixing protrusion 13. The connection between the two can be, but is not limited to, binding, clamping, bolt connection, lock connection, etc.

[0055] In some embodiments, at least one of the two ends of the lanyard 21 is detachably connected to the supporting assembly 10. The detachable connection may be, but is not limited to, a buckle, a lock connection, a binding, etc. It can be seen that when the charging cable needs to be wound around the supporting assembly 10, one end of the lanyard 21 can be removed from the supporting assembly 10, and after the charging cable is wound, one end of the lanyard 21 can be reconnected to the supporting assembly 10. In this way, the installation operation of the limiter 100 is convenient.

[0056] In some embodiments, the lanyard 21 includes a buckle 211 and at least two rope segments 212, and two adjacent rope segments 212 are connected by the buckle 211. It can be seen that when the charging cable needs to be wound around the supporting assembly 10, the buckle 211 can be released to disconnect the two rope segments 212, which makes it easier to wind the charging cable around the supporting assembly 10.

[0057] The buckle 211 may be, but is not limited to, a locking structure, a snap lock, etc.

[0058] Specifically, the hanging rope 21 includes a buckle 211 and two rope segments 212, the two rope segments 212 are connected by the buckle 211, one end of one rope segment 212 is connected to the first support member 11 of the supporting assembly 10, and one end of the other rope segment 212 is connected to the second support member 12 of the supporting assembly 10.

[0059] In some embodiments, please refer to Figure 1 , and also includes an anti-lost component 40, one end of the anti-lost component 40 is connected to the supporting component 10, and the other end is used to connect to the charging pile 200. In this way, the anti-lost component 40 can effectively prevent the limiter 100 from being lost.

[0060] For further information, please refer to Figure 1 The anti-lost component 40 includes an anti-lost rope 41 and locking pieces 42 connected to both ends of the anti-lost rope 41, wherein one locking piece 42 is fixed on the supporting component 10, and the other locking piece 42 is fixed on the charging pile 200.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
