Description

Technical Field

[0001] This utility model belongs to the field of charging gun technology, and relates to a charging gun body, particularly a charging gun body and charging gun that can be quickly installed. Background Technology

[0002] In existing technologies, after repeated plugging and unplugging operations, the plug terminals of charging guns are prone to ablation due to factors such as electric arcing and increased contact resistance, affecting their electrical performance and operational safety, thus requiring replacement and maintenance. Traditional charging gun structures typically use a fixed connection (such as crimping or welding) between the internal conductive contacts and the core of the power supply cable. Once the plug terminals are damaged, the entire charging gun must be replaced, resulting in high maintenance costs and time-consuming disassembly and assembly, significantly reducing operational efficiency.

[0003] To address these issues, some improved charging guns adopt a modular design concept, separating the connector of the integrated cable (i.e., the "cable assembly") from the charging gun body (i.e., the "plug body") into a detachable structure. When the plug end of the charging gun is burned or worn, only the damaged part of the gun body needs to be replaced, while the intact cable and connector assembly is preserved, thereby significantly reducing replacement costs and improving maintenance efficiency.

[0004] However, because the connector and the charging gun body are detachable, the joint area is easily vulnerable to the intrusion of environmental contaminants (such as moisture and dust). To ensure that the charging gun as a whole meets the corresponding IP protection level, an end cap is usually installed at the connection point for sealing protection. In the existing technology, this end cap is mostly mechanically fixed to the charging gun body by screws or other fasteners. At the same time, to meet safety supervision requirements, a lead seal structure (such as a lead seal rope or lead seal hole) is often set on the end cap to prevent unauthorized disassembly. Although such a structure can ensure the sealing and safety of the connection, it has problems such as cumbersome disassembly and assembly steps, reliance on special tools, and limited maintenance efficiency, which is not conducive to rapid inspection and on-site maintenance. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a charging gun body that is easy to assemble and disassemble and improves work efficiency.

[0006] The objective of this utility model can be achieved through the following technical solution: a charging gun body that enables quick installation, comprising:

[0007] The shell has a connecting cavity at one end along the axial direction of the shell, and the connecting cavity is connected to the internal space of the shell. A first positioning part is provided on the plane where the cavity opening of the connecting cavity is located, or a first positioning part is provided on the outer peripheral surface of the shell.

[0008] The cover is detachably connected to the connecting cavity, and a second positioning part is provided on the cover to engage with the first positioning part. A rope-threading channel for installing the lead sealing rope is provided at the engagement position between the first positioning part and the second positioning part.

[0009] In the aforementioned quick-installation charging gun body, the housing and the cover are connected by a rotation. When the cover is connected to the housing but not locked, the positions of the first positioning part and the second positioning part are misaligned. When the cover is locked to the housing, the positions of the first positioning part and the second positioning part correspond to each other.

[0010] In the aforementioned quick-release charging gun body, during the rotation of the cover, the second positioning part is located within the area defined by the outermost edge of the cover, or the second positioning part is located above the first positioning part.

[0011] In the aforementioned quick-installation charging gun body, one end of the second positioning part is rotatably connected to the cover, and the other end of the second positioning part is provided with a deformation part. The first positioning part is provided with a protrusion. The connection between the second positioning part and the first positioning part is completed by the snap-fit ​​between the deformation part and the protrusion.

[0012] In the aforementioned quick-installation charging gun body, the second positioning part is U-shaped, with its open end rotatably connected to the cover, and the deformation part located at the closed end of the second positioning part. When the deformation part engages with the protrusion, the first positioning part is inserted into the area enclosed by the open end and the closed end of the second positioning part.

[0013] In the aforementioned quick-release charging gun body, a first lanyard hole and a second lanyard hole are respectively provided on the first positioning part and the second positioning part. The first lanyard hole passes through the first positioning part, and the second lanyard hole is located in the deformation part of the second positioning part and passes through the deformation part of the second positioning part. When the second positioning part is engaged with the first positioning part, the position of the first lanyard hole corresponds to the position of the second lanyard hole, forming a lanyard channel for the lead sealing rope.

[0014] In the aforementioned quick-release charging gun body, the cover includes a cover body, and a rotating handle protruding from the surface of the cover body is provided on the cover body. The second positioning part is rotatably connected to the rotating handle, and the rotation plane of the second positioning part is perpendicular to the rotation plane of the cover body.

[0015] In the aforementioned quick-release charging gun body, one end of the handle that is rotatably connected to the second positioning part is recessed inward to form a relief groove, wherein the distance between the bottom of the relief groove and the deformation part is greater than the distance between the plane where the relief groove is located and the deformation part.

[0016] In the aforementioned quick-installation charging gun body, the clearance groove is arranged in an arc shape.

[0017] This utility model also provides a charging gun, including the charging gun body that enables quick installation.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) The present invention provides a charging gun body that enables quick installation. The connection and locking between the housing and the cover are completed by the positioning and locking between the first positioning part and the second positioning part, thereby realizing tool-free installation and disassembly between the housing and the cover, which is convenient and reliable, thereby improving the assembly efficiency of the charging gun.

[0020] (2) The clearance groove creates a gap between the handle and the first positioning part, allowing the lead seal rope to pass through, which improves the smoothness and convenience of threading the lead seal rope, while preventing the lead seal rope from being damaged during the threading process.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figures 1 to 4 As shown, the present invention provides a charging gun body that enables quick assembly, comprising:

[0032] The housing 100 has a connecting cavity 110 at one end along the axial direction of the housing 100, and the connecting cavity 110 is connected to the internal space of the housing 100. A first positioning part 120 is provided on the plane where the cavity opening of the connecting cavity 110 is located, or the first positioning part 120 is provided on the outer peripheral surface of the housing 100.

[0033] The cover 200 is detachably connected to the connecting cavity 110, and a second positioning part 210 is provided on the cover 200 to form a snap-fit ​​with the first positioning part 120. A rope-threading channel for installing the lead sealing rope 300 is provided at the snap-fit ​​position between the first positioning part 120 and the second positioning part 210.

[0034] It is worth mentioning that in this embodiment, the lead seal rope 300 is mainly used for security and verification. Once installed, if the lead seal rope 300 is damaged or removed, it usually means that someone is attempting to use the charging device without authorization or to disassemble or repair it. It acts as a physical barrier to prevent unauthorized use. Furthermore, by checking whether the lead seal rope 300 is intact, it is possible to quickly determine whether the charging device has been opened or tampered with, which helps maintain the security and reliability of the charging device.

[0035] The present invention provides a charging gun body that enables quick assembly. The connection and locking between the housing 100 and the cover 200 are completed by the positioning snap-fit ​​between the first positioning part 120 and the second positioning part 210, thereby realizing tool-free installation and disassembly between the housing 100 and the cover 200, which is convenient and reliable, and thus improves the assembly efficiency of the charging gun.

[0036] Preferably, the housing 100 and the cover 200 are connected by a rotational connection, and the locking or unlocking between the housing 100 and the cover 200 is completed by rotation. When the cover 200 is connected to the housing 100 but not locked, the positions of the first positioning part 120 and the second positioning part 210 are misaligned. When the cover 200 is locked to the housing 100, the positions of the first positioning part 120 and the second positioning part 210 correspond to each other.

[0037] It is worth mentioning that, in this embodiment, the rotary connection includes two methods: rotary snap-fit ​​and threaded connection. When the housing 100 and the cover 200 are connected by rotary snap-fit, the housing 100 is provided with a slot, and the cover 200 is provided with a corresponding engaging block. The slot includes a guide groove and a snap-fit ​​groove that are interconnected. When the housing 100 and the cover 200 are connected, the block on the cover 200 is first inserted into the guide groove, and then the cover 200 is rotated so that the block engages in the snap-fit ​​groove, thereby locking the housing 100 and the cover 200. When unlocking is required, the cover 200 is rotated in the opposite direction to release the connection between the block and the snap-fit ​​groove, and then the block moves along the guide groove to separate the cover 200 from the housing 100.

[0038] It is worth mentioning that, under normal circumstances, the guide groove and the snap-fit ​​groove are spliced ​​together to form an L-shaped structure. The setting position of the snap-fit ​​groove and the setting position of the snap-fit ​​block can be interchanged. That is, the snap-fit ​​groove is set on the cover 200, and the corresponding snap-fit ​​block is set on the housing 100.

[0039] To further explain, when the slot or block is provided on the housing 100, the slot or block is provided on the cavity wall of the connecting cavity 110; when the slot or block is provided on the cover 200, the slot or block is provided on the outer circumferential surface of the cover 200.

[0040] Furthermore, when the housing 100 and the cover 200 are connected by threads, the housing 100 is provided with internal threads and the cover 200 is provided with external threads. The locking or unlocking of the housing 100 and the cover 200 is completed by the screwing between the internal threads and the external threads.

[0041] It is worth mentioning that the positions of the internal thread and the external thread can be interchanged, that is, the external thread is set on the housing 100, and the internal thread is set on the cover 200.

[0042] To further explain, when the internal or external thread is provided on the housing 100, the internal or external thread is provided on the cavity wall of the connecting cavity 110; when the internal or external thread is provided on the cover 200, the internal or external thread is provided on the outer circumferential surface of the cover 200.

[0043] It is worth mentioning that regardless of whether the connection between the housing 100 and the cover 200 is a rotary snap-fit ​​or a threaded connection, the connection method ensures the reliability of the connection between the housing 100 and the cover 200 when the charging gun is stationary. However, as is known from the prior art, the charging gun is not always stationary. When the user inserts the charging gun into the charging port of the corresponding vehicle to charge the vehicle, the charging gun is in motion during this process of being removed from the charging station and then inserted into the charging port; when the vehicle is fully charged, the charging gun is unplugged from the charging port and then plugged into the charging station, which is also a process of motion. In addition, the charging gun needs to be repeatedly inserted and unplugged during pre-shipment testing. If only a rotary snap-fit ​​or threaded connection is used, the housing 100 and the cover 200 may loosen at their connection point, causing them to detach. Therefore, in order to further improve the reliability of the connection between the housing 100 and the cover 200, a first positioning part 120 and a second positioning part 210 are provided. The connection reliability between the first positioning part 120 and the second positioning part 210 is further improved through the snap-fit ​​cooperation between the two. In addition, the connection position between the first positioning part 120 and the second positioning part 210 can also be used as the installation position of the lead sealing rope 300, which reflects two effects of one structure.

[0044] Furthermore, since the first positioning part 120 is located on the end face where the cavity opening of the connecting cavity 110 is located, that is, the protrusion 121 of the first positioning part 120 is on the end face where the cavity opening of the connecting cavity 110 is located, when the first positioning part 120 and the second positioning part 210 are engaged, the second positioning part 210 is generally engaged into the first positioning part 120 from top to bottom. However, since the housing 100 and the cover 200 are rotatably connected, the second positioning part 210 on the cover 200 is rotatably connected to the cover 200 to avoid interference with the first positioning part 120 during the rotation of the cover 200. Specifically, when the cover 200 is rotating, the second positioning part 210 is located within the area defined by the outermost edge of the cover 200, or the second positioning part 210 is located above the first positioning part 120. When the cover 200 is rotated to the preset position, that is, after the cover 200 and the housing 100 are locked, the position of the second positioning part 210 corresponds to the position of the first positioning part 120. At this time, rotating the second positioning part 210 can complete the snap-fit ​​engagement between the second positioning part 210 and the first positioning part 120.

[0045] Preferably, the cover 200 includes a cover body 220, and a rotating handle 230 protruding from the surface of the cover body 220 is provided on the cover body 220. The cover 200 can be rotated by the rotating handle 230. The second positioning part 210 is rotatably connected to the rotating handle 230, and the rotation plane of the second positioning part 210 is perpendicular to the rotation plane of the cover body 220.

[0046] It is worth mentioning that the cover 220 is provided with an installation surface 221, and the handle 230 is provided on the installation surface 221. When the cover 220 is screwed into the connecting cavity 110, the installation surface 221 is flush with the plane where the cavity opening of the connecting cavity 110 is located.

[0047] Preferably, the second positioning part 210 is arranged in a U-shape. The open end of the second positioning part 210 is rotatably connected to the rotating handle 230 through a rotating shaft 240. The closed end of the second positioning part 210 is provided with a snap-fit ​​surface 211. The area enclosed between the end face of the rotating handle 230 that is rotatably connected to the open end of the second positioning part 210 and the snap-fit ​​surface 211 of the second positioning part 210 forms an insertion fit with the first positioning part 120.

[0048] More preferably, the first positioning part 120 is provided with a protrusion 121, and the protrusion 121 is provided on the same side as the outer surface of the housing 100. When the second positioning part 210 is engaged with the first positioning part 120, the protrusion 121 is engaged at the edge of the engagement surface 211.

[0049] It is worth mentioning that the surface of the protrusion 121 is a smooth arc-shaped surface, and the locking surface 211 of the closed end of the second positioning part 210 is elastic and is a deformable part. During the rotation of the second positioning part 210, the lower end surface of the locking surface 211 first contacts the protrusion 121 on the first positioning part 120, and then the second positioning part 210 is continuously pressed down, causing the locking surface 211 to deform and surround the protrusion 121 in the area enclosed between the end face of the rotating handle 230 and the locking surface 211. When the second positioning part 210 is rotated into place, the protrusion 121 on the first positioning part 120 will jump out of the area enclosed between the end face of the rotating handle 230 and the locking surface 211. At this time, the elastic deformation of the locking surface 211 disappears, so that the upper end surface of the locking surface 211 engages with the protrusion 121, thus completing the engagement between the first positioning part 120 and the second positioning part 210.

[0050] Preferably, the first positioning part 120 and the second positioning part 210 are respectively provided with a first rope hole 122 and a second rope hole 212, and the first rope hole 122 passes through the first positioning part 120, and the second rope hole 212 is located at the closed end of the second positioning part 210 and passes through the closed end of the second positioning part 210. When the second positioning part 210 is engaged with the first positioning part 120, the position of the first rope hole 122 corresponds to the position of the second rope hole 212, forming a rope passage for the lead sealing rope 300.

[0051] Preferably, one end of the handle 230 that is rotatably connected to the second positioning part 210 is recessed inward to form a relief groove 231. The distance between the bottom of the relief groove 231 and the deformation part is greater than the distance between the plane where the groove opening of the relief groove 231 is located and the deformation part. The relief groove 231 is arc-shaped. The relief groove 231 creates a gap between the handle 230 and the first positioning part 120 that allows the lead sealing rope 300 to pass through, improving the smoothness and convenience of threading the lead sealing rope 300, while preventing damage to the lead sealing rope 300 during the threading process.
