Description

Technical Field

[0001] The embodiments of the present invention belong to the technical field of Mode 2 charging guns, and particularly relate to an integrated Mode 2 charging gun with a straight handle and integrated control board. Background Technology

[0002] Currently, charging guns for new energy electric vehicles mainly include Mode 2 charging guns and Mode 3 AC charging guns. Mode 2 charging guns, also called Mode 2 AC charging guns, are household charging guns that use household power. Since there are no charging stations, the control board of a Mode 2 charging gun is located inside the charging gun's housing, and this control board is relatively large and long. In existing technology, to accommodate the control board, the charging gun housing is generally designed as a dual-cavity structure or a single-cavity front and rear shell structure. For dual-cavity charging gun housings, the outer shell has two cavities, one upper and one lower. The lower cavity integrates the control board, and the upper cavity serves as a handle. The overall structure of the gun is relatively complex, large in size, and requires complex assembly. For charging gun housings with a single cavity front and rear shell structure, the control board is integrated into the outer shell at the gun head end. Since the gun head itself has a certain length and the control board itself also has a certain length, integrating the control board into the outer shell at the gun head end results in a relatively long outer shell at the gun head end. At the same time, the tail of this type of charging gun housing is usually equipped with a handle, and the internal space of the housing at the handle position is empty. This results in the overall size of the charging gun being relatively long, top-heavy, and with an uncoordinated shape and a complex internal structure.

[0003] In summary, the existing Mode 2 charging gun has technical problems such as excessive length, inconsistent shape, unused internal space in the charging gun housing, and complex internal structure.

[0004] Application content

[0005] To address the shortcomings of the existing technology, this invention provides an integrated Mode 2 charging gun with a straight handle and integrated control board, thereby reducing the overall size of the Mode 2 charging gun, simplifying the housing structure of the Mode 2 charging gun, and making full use of the internal space of the housing of the Mode 2 charging gun, resulting in a Mode 2 charging gun that is short in size, simple in structure, and aesthetically pleasing in appearance.

[0006] This invention provides an integrated Mode 2 charging gun with a straight handle and integrated control board, comprising: an integrated shell body, a control board, a gun head module, and a tail cap sealing assembly. The integrated shell body has a linear internal cavity formed integrally along a straight line. The control board is installed within the linear internal cavity of the shell body, extending transversely through the middle of the shell body, with one end extending into the head of the shell body and the other end extending into the tail of the shell body. The gun head module is assembled at the head of the shell body to seal the interior of the integrated shell body. The tail cap sealing assembly is assembled at the tail of the shell body, through which a cable passes into the interior of the integrated shell body. The tail cap sealing assembly, the tail of the shell body, and the cable together seal the interior of the integrated shell body.

Detailed Implementation

[0013] To enable those skilled in the art to better understand the present invention, the technical solutions of this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0014] Example 1

[0015] See Figures 1-11 This embodiment provides an integrated Mode 2 charging gun with a straight handle and integrated control board 1600. The integrated Mode 2 charging gun includes an integrated shell body 800, a control board 1600, a gun head module 200, and a tail cap sealing assembly 130. The interior of the integrated shell body 800 is integrally formed into a straight-line inner cavity. The control board 1600 is installed in the straight-line inner cavity of the shell body, and the control board 1600 traverses the interior of the middle portion 8001 of the integrated shell body 800. The control board 1600 extends horizontally through the interior of the head 8002 of the integrated shell body 800, and the other end extends horizontally through the interior of the tail 8003 of the integrated shell body 800. The gun head module 200 is assembled on the head 8002 to seal the interior of the integrated shell body 800. The tail cap sealing assembly 130 is assembled on the tail 8003, through which a cable passes. This cable can be a three-prong cable 1100. The tail cap sealing assembly 130, the tail 8003, and the cable together seal the interior of the integrated shell body 800, thereby reducing the overall size of the Mode 2 charging gun, simplifying its shell structure, and fully utilizing the internal space of the Mode 2 charging gun, resulting in a short, simple, and aesthetically pleasing integrated Mode 2 charging gun. The control board 1600 includes internal terminals and a connecting cable 1700.

[0016] It should be noted that the housing of the Mode 2 charging gun specifically designed for mounting the control board 1600 is primarily a dual-cavity structure or a single-cavity front and rear shell structure. For the dual-cavity structure, the charging gun housing has two cavities, one upper and one lower. The lower cavity integrates the control board 1600, while the upper cavity serves as a handle. The overall structure of the gun is relatively complex, larger in size, and more difficult to assemble. For the single-cavity front and rear shell structure, the control board 1600 is integrated into the housing at the gun head end. Since both the gun head and the control board 1600 have a certain length, integrating the control board 1600 into the housing at the gun head end results in a relatively long housing at the gun head end. Furthermore, this type of charging gun housing typically has a handle at the rear, leaving the internal space of the housing at the handle position empty. This results in a long overall size for the charging gun, a top-heavy appearance, an uncoordinated shape, and a complex internal structure. In this embodiment, the interior of the head 8002, the middle 8001, and the tail 8003 of the shell body are integrally connected along a straight line to form a linear inner cavity. When the control board 1600 of the Mode 2 charging gun is installed, the control board 1600 passes through the interior of the middle 8001 of the shell body, with one end of the control board 1600 passing through the interior of the head 8002 and the other end passing through the interior of the tail 8003. This reduces the overall volume of the Mode 2 charging gun, simplifies the shell structure of the Mode 2 charging gun, and makes full use of the internal space of the shell of the Mode 2 charging gun, resulting in an integrated Mode 2 charging gun that is short in size, simple in structure, and aesthetically pleasing in appearance.

[0017] It is understandable that, since the integrated mode 2 charging gun with straight handle integrated control board 1600 provided in this embodiment has an integrated shell body 800, that is, the shell body includes a shell body head 8002, a shell body tail 8003, and a shell body middle part 8001 located between the shell body head 8002 and the shell body tail 8003, the interior of the shell body head 8002, the interior of the shell body middle part 8001, and the interior of the shell body tail 8003 are integrally connected along a straight line to form a straight shell body internal cavity. Therefore, compared with the charging gun shell with a dual cavity structure, the integrated mode 2 charging gun with straight handle integrated control board 1600 provided in this embodiment does not have the two cavities of a charging gun shell with a dual cavity structure, which makes the overall volume of the mode 2 charging gun smaller, the shell structure simpler, the size shorter, and the appearance more harmonious and beautiful. Meanwhile, compared to the front and rear shell structure of a single cavity, the integrated mode two charging gun with a straight handle integrated control board 1600 provided in this embodiment does not have the problem of a long gun head shell when the control board 1600 is integrated into the charging gun shell. It does not require a handle to be set at the tail of the charging gun shell, leaving the internal space of the shell at the handle position empty. This avoids technical problems such as a long overall size of the charging gun, top-heavy appearance, uncoordinated shape, and complex internal structure of the shell.

[0018] In some preferred embodiments, the size of the head 8002 of the shell body is larger than the size of the middle part 8001 and the tail 8003 of the shell body, forming a gradient structure in which the tail 8003 and the middle part 8001 of the shell body gradually increase in size towards the head 8002 of the shell body.

[0019] It should be noted that, in this embodiment, since the size of the head 8002 of the shell body is larger than the size of the middle part 8001 and the tail part 8003 of the shell body, the space of the linear shell body cavity corresponding to the head 8002 and the overall volume of the head 8002 are relatively large compared to the middle part 8001 and the tail part 8003, which can be used to house other components of the charging gun. For example, the head 8002 of the shell body may include a limiting groove 43 for a micro switch assembly, which communicates with the linear shell body cavity; the micro switch assembly 40 is used to be installed in the limiting groove 43 and electrically connected to the control board 1600. Alternatively, the portion of the control board 1600 that extends into the interior of the head 8002 of the shell body may be a double-layer PCB board. For example, a limiting and fixing groove 80020 for the gun head module is provided on one side of the head 8002 of the shell body, which is used to limit and fix the gun head module 200. The gun head module 200 can be fixed to the limiting and fixing groove 80020 using the gun head fixing screw 100. A tail limiting and fixing groove 80030 is provided on one side of the tail 8003 of the shell body, which is used to limit and fix the tail cap sealing assembly 130 and the cable of the Mode 2 charging gun. It can be understood that since the tail cap sealing assembly 130 and the cable of the Mode 2 charging gun are relatively small compared to the gun head module 200, the limiting and fixing groove 80020 for the gun head module is provided on one side of the head 8002 of the shell body to limit and fix the gun head module 200, which can make full use of the space of the head 8002 of the shell body.

[0020] It should also be noted that, due to the relatively large overall volume of the head 8002 of the shell body, it is not suitable as a part for the user to hold. Conversely, since the dimensions of the middle part 8001 and the tail part 8003 of the shell body are smaller than the dimensions of the head 8002, they can be used as parts for the user to hold. For example, the tail part 8003 and the middle part 8001 of the shell body together form the handle of the charging gun of mode two. The handle forms a concave shell relative to the head 8002 of the shell body to fit the user's grip. Alternatively, the concave shell includes a concave side 8004, the surface of which is a curved surface with a set curvature to fit the user's grip. Another example is that the concave shell includes a convex side 8005, located on the concave side 8004, the surface of which is a curved surface with a set curvature to fit the user's grip. For example, the convex side 8005 is provided with an LED light guide strip mounting hole 901. The LED light guide strip mounting hole 901 is connected to the inner cavity of the linear shell body. After the LED light guide strip 900 is installed in the LED light guide strip mounting hole 901, the light emitted by the LED indicator 1601 on the control board 1600 is guided out by the LED light guide strip 900.

[0021] It is understandable that, since the tail portion 8003 and the middle portion 8001 of the shell body together form the handle of the Mode 2 charging gun, the handle of the Mode 2 charging gun in this embodiment is a straight handle, which is basically in the same straight line direction as the integrated shell. In addition, since the convex side 8005 is provided with an LED light guide strip mounting hole 901, and the LED light guide strip mounting hole 901 is connected to the inner cavity of the straight shell body, after the LED light guide strip 900 is installed in the LED light guide strip mounting hole 901, the light emitted by the LED indicator 1601 on the control board 1600 is guided out through the LED light guide strip 900. Therefore, the LED indicator 1601 does not need to transmit light twice, nor does it need to pass through other components.

[0022] In some alternative embodiments, the mounting holes 901 for the LED light guide strip can also be provided at the tail 8003 and the middle part 8001 of the housing body. Correspondingly, a string of LED indicator lights 1601 can be provided on the control board 1600 to form a running light.

[0023] In some preferred embodiments, a limiting groove is provided in the inner cavity of the linear shell body, and the control board 1600 is inserted into the limiting groove. The control board 1600 can be a single-layer PCB board, or the portion of the control board 1600 that extends transversely into the interior of the head 8002 of the shell body can be a double-layer PCB board.

[0024] Example 2

[0025] See Figures 1-11 This embodiment provides a micro switch assembly 40, which includes a mechanical button 500, a micro switch sealing sleeve 300, and a micro switch 400. The mechanical button 500 is connected to the integrated housing body 800 via a lever structure 41. When inserting or removing the gun, the mechanical button 500 is pressed. When the mechanical button 500 is pressed, the lever structure 41 lifts the mechanical button 500. When the mechanical button 500 is released, the lever structure 41 presses the mechanical button 500 down to seal the exterior and interior of the integrated housing body 800. The micro switch sealing sleeve 300 is assembled in the through groove 80021 of the integrated housing body 800. The through groove 80021 connects to the interior of the integrated housing body 800. The micro switch sealing sleeve 300 isolates the micro switch 400 from the exterior of the housing connected to the through groove 80021 to seal the micro switch 400. The micro switch 400 is located in the through groove 80021 and is electrically connected to the control board 1600 assembled inside the integrated housing body 800, thereby simplifying the structure and process complexity of the Mode 2 charging gun and reducing the cost of the Mode 2 charging gun.

[0026] It should be noted that in this embodiment, since the mechanical button 500 is connected to the integrated shell body 800 via the lever structure 41, when the mechanical button 500 is pressed, the lever structure 41 lifts the mechanical button 500, thereby achieving press control of the mechanical button 500. The structure is simple and easy to use. Specifically, the mechanical button 500 is pressed when inserting or removing the gun; otherwise, the mechanical button 500 is in its natural state. For example, when the mechanical button 500 is released, the lever structure 41 presses down on the mechanical button 500 to isolate and seal the exterior and interior of the integrated shell body 800. At this time, the mechanical button 500 acts as the top cover of the integrated shell body 800, isolating and sealing the exterior and interior of the integrated shell body 800, thus providing both sealing protection and press control. The structure is simple.

[0027] It should also be noted that, since the micro switch sealing sleeve 300 is assembled in the through groove 80021 of the integrated housing body 800, and the through groove 80021 connects to the interior of the integrated housing body 800, the micro switch sealing sleeve 300 isolates the micro switch 400 from the outside of the housing connected by the through groove 80021, thereby sealing the micro switch 400. This further seals the device under the sealing action of the mechanical button 500, improving the sealing performance of the Mode 2 charging gun.

[0028] It should also be noted that the location of the micro switch 400 in the through slot 80021 can mean that the micro switch 400 is located inside the through slot 80021 or below the through slot 80021. When the micro switch 400 is located inside the through slot 80021, the micro switch 400 is located on the integrated housing body 800. When the micro switch 400 is located below the through slot 80021, the micro switch 400 is located on the circuit board inside the integrated housing body 800.

[0029] In some preferred embodiments, the micro switch 400 is externally sleeved with the micro switch sealing sleeve 300, and after being assembled as a whole with the micro switch sealing sleeve 300, it is fitted into the through groove 80021 of the integrated housing body 800. Further, the micro switch 400 is connected to two cables, assembled as a whole with the micro switch sealing sleeve 300, and fitted into the through groove 80021 of the integrated housing body 800. The two cables are connected to a two-core connector plug 402, which is inserted into a corresponding two-core connector female socket 1602 on the control board 1600. Wherein, the two cables are micro switch connecting wires 401.

[0030] It should be noted that while the micro switch 400 can achieve press control and sealing when placed in the through slot 80021, it requires two cables to be connected and assembled with the micro switch sealing sleeve 300 as a whole within the through slot 80021 of the integrated housing body 800. These two cables connect to a two-core connector 402, which in turn connects to a corresponding two-core connector 1602 on the control board 1600. This means the micro switch 400 needs to be wired before being connected to the control board 1600, resulting in a complex connection process. Furthermore, the micro switch 400 on the housing requires high sealing performance, for example, meeting IP67 waterproof standards, and requires secondary waterproofing design with the housing. Therefore, placing the micro switch 400 on the control board 1600 below the through slot 80021 is an improved solution, as detailed below.

[0031] In some improved embodiments, the micro switch 400 is disposed on the control plate 1600 below the through slot 80021, separately from the micro switch sealing sleeve 300, to simplify the assembly process and reduce the number of parts, and reduce intermediate connecting wires and connectors. Furthermore, when the lever structure 41 is raised, the mechanical button 500 releases the micro switch sealing sleeve 300 from its state of pushing the micro switch sealing sleeve 300, and the micro switch sealing sleeve 300 returns to its original position from its deformed state of pushing the contact rod of the micro switch 400; when the lever structure 41 is pressed down, the mechanical button 500 pushes the micro switch sealing sleeve 300, causing the micro switch sealing sleeve 300 to push the contact rod of the micro switch 400 to move, triggering a feedback signal from the micro switch 400.

[0032] It should be noted that after the micro switch 400 is mounted on the control board 1600, the mechanical button 500 and the micro switch 400 can be linked for activation, resulting in a simple structure and waterproofing. For example, when the lever structure 41 is raised, the mechanical button 500 releases the micro switch sealing sleeve 300 from its state of pushing against it, and the micro switch sealing sleeve 300 returns to its original position from its deformed state of pushing against the contact rod of the micro switch 400. Similarly, when the lever structure 41 is pressed down, the mechanical button 500 pushes against the micro switch sealing sleeve 300, causing the micro switch sealing sleeve 300 to push against the contact rod of the micro switch 400, thus triggering a feedback signal from the micro switch 400.

[0033] It should also be noted that the micro switch 400 is mounted on the control board 1600 and is separate from the micro switch sealing sleeve 300. Therefore, it is not necessary to assemble the micro switch sealing sleeve 300 with the micro switch 400, further reducing the waterproofing requirements for the micro switch 400. Furthermore, the micro switch 400 only needs to be directly soldered to the control board 1600 for conductivity. It is not necessary to connect two cables to the micro switch 400, assemble it with the micro switch sealing sleeve 300 as a whole, and then assemble it into the through groove 80021 of the integrated housing body 800, connect the two cables to the two-core connector plug 402, and then insert the two-core connector plug 402 into the corresponding two-core connector female socket 1602 on the control board 1600. This simplifies the process and improves efficiency.

[0034] In a further improved embodiment, the mechanical button 500 is disposed within the limiting groove 43 of the micro switch assembly, and the limiting groove 43 of the micro switch assembly is disposed on the integrated housing body 800; when the lever structure 41 is pressed down, the mechanical button 500 acts as a top cover to seal the limiting groove 43 of the micro switch assembly. Furthermore, the mechanical button 500 includes a push rod 44, which pushes or releases the micro switch sealing sleeve 300; when the lever structure 41 is pressed down, the push rod 44 pushes the micro switch sealing sleeve 300, and together with the micro switch sealing sleeve 300, seals the micro switch 400.

[0035] It should be noted that the mechanical button 500 is disposed within the limiting groove 43 of the micro switch assembly. When the lever structure 41 is pressed down, the mechanical button 500 acts as a top cover to seal the limiting groove 43 of the micro switch assembly. The mechanical button 500 includes a push rod 44, which pushes or releases the micro switch sealing sleeve 300. When the lever structure 41 is pressed down, the push rod 44 pushes the micro switch sealing sleeve 300, and together with the micro switch sealing sleeve 300, seals the micro switch 400. In this way, the mechanical button 500 acts as a top cover to seal the limiting groove 43 of the micro switch assembly, which can improve the waterproof performance of the Mode 2 charging gun and prevent the micro switch sealing sleeve 300 from popping out of the Mode 2 charging gun housing, thus providing a further limiting and sealing effect on the micro switch sealing sleeve 300. In addition, the limiting groove 43 of the micro switch assembly can also seal and limit the periphery of the mechanical button 500, and together with the mechanical button 500, they play a sealing role, improving the waterproof and dustproof performance of the Mode 2 charging gun.

[0036] In some preferred embodiments, the lever structure 41 is disposed within the limiting groove 43 of the micro switch assembly, and includes a mechanical button fixing shaft 600, a spring 700, and a limiting post 45. The mechanical button fixing shaft 600 passes through both sides of the mechanical button 500 and both sides of the limiting groove 43 of the micro switch assembly, fixing the mechanical button 500 within the limiting groove 43 of the micro switch assembly. The limiting post 45 is disposed on the bottom surface of the limiting groove 43 of the micro switch assembly, and the spring 700 is mounted on the limiting post 45 with one end abutting against the bottom surface of the mechanical button 500. Further, the micro switch sealing sleeve 300 is W-shaped.

[0037] It should be noted that, since the lever structure 41 includes a mechanical button fixing shaft 600, a spring 700, and a limiting post 45, the mechanical button fixing shaft 600 passes through both sides of the mechanical button 500 and both sides of the limiting groove 43 of the micro switch assembly, fixing the mechanical button 500 in the limiting groove 43 of the micro switch assembly. The limiting post 45 is set on the bottom surface of the limiting groove 43 of the micro switch assembly. The spring 700 is mounted on the limiting post 45 and one end abuts against the bottom surface of the mechanical button 500. Therefore, when the mechanical button 500 is pressed, the spring 700 will compress, lifting the mechanical button 500. When the mechanical button 500 is released, the spring 700 will return to its original position and extend, pressing the mechanical button 500 down. In addition, since the micro switch sealing sleeve 300 is set in a W shape, it is convenient to set the shape of the through groove 80021 of the integrated shell body 800, and to assemble the micro switch sealing sleeve 300 into the through groove 80021 of the integrated shell body 800.

[0038] Example 3

[0039] See Figures 1-11 This embodiment provides a tail cap sealing assembly 130, which includes a tail cap 1300. The tail cap 1300 is formed by partially splitting off the tail portion 8003 of the shell body. After the tail cap 1300 is separated from the tail portion 8003 of the shell body, a tail limiting and fixing groove 80030 is formed. The tail cap 1300 is used to assemble into the tail limiting and fixing groove 80030, forming a limiting through hole 80033 with the tail limiting and fixing groove 80030. When the cable passes through the limiting through hole 80033 and enters the interior of the integrated shell body 800, the limiting through hole 80033 clamps and fixes the cable, and together with the cable, isolates and seals the interior and exterior of the integrated shell body 800, thereby simplifying the structure of the tail cap 1300 assembly of the Mode 2 charging gun and reducing the cost of the tail cap 1300 assembly of the Mode 2 charging gun.

[0040] It should be noted that in the prior art, the tail cap 1300 is typically obtained in two ways. One is by cutting a complete piece of the shell tail 8003 as the tail cap 1300. The other is by further dividing the cut-out complete shell tail 8003 into two separate tail caps 1300. When using the complete shell tail 8000 as the tail cap 1300 to seal the shell tail 8003 with other components of the tail cap 1300 assembly, at least one cable clamp is required in the other components of the tail cap 1300 assembly, increasing cost and structural complexity. When using two separate tail caps 1300 to seal the shell tail 8003 with other components of the tail cap 1300 assembly, the two separate tail caps 1300 further increase cost and structural complexity.

[0041] Compared with the prior art where a complete shell tail portion is cut out of the shell body tail portion 8003 as the tail cover 1300, the tail cover 1300 proposed in this embodiment is formed by partially splitting the shell body tail portion 8003. When the tail cover 1300 is assembled into the tail portion limiting and fixing groove 80030, it forms a limiting through hole 80033 with the tail portion limiting and fixing groove 80030. When the cable passes through the limiting through hole 80033 into the interior of the integrated shell body 800, the limiting through hole 80033 clamps and fixes the cable, and together with the cable, isolates and seals the interior and exterior of the integrated shell body 800. It is not necessary to equip at least one additional cable fixing clip, thereby simplifying the structure of the tail cover 1300 assembly of the Mode 2 charging gun and reducing the cost of the tail cover 1300 assembly of the Mode 2 charging gun.

[0042] Compared with the prior art of two separate tail caps 1300, the tail cap 1300 proposed in this embodiment is formed by partially splitting from the tail portion 8003 of the shell body. When the tail cap 1300 is assembled into the tail limiting and fixing groove 80030, it forms a limiting through hole 80033 with the tail limiting and fixing groove 80030. When the cable passes through the limiting through hole 80033 and enters the interior of the integrated shell body 800, the limiting through hole 80033 clamps and fixes the cable, and together with the cable, isolates and seals the interior and exterior of the integrated shell body 800. This reduces the number of tail caps 1300, thereby simplifying the structure of the tail cap 1300 assembly of the Mode 2 charging gun and reducing the cost of the tail cap 1300 assembly of the Mode 2 charging gun.

[0043] It should be noted that in this embodiment, partial splitting is a concept relative to overall splitting in the prior art. In the prior art, a complete shell tail section is cut out from the tail section 8003 of the shell body as the tail cover 1300, which is an overall splitting method.

[0044] In some preferred embodiments, when the tail cap 1300 is partially split from the tail portion 8003 of the shell body, half of the tail portion 8003 of the shell body is split. Further, when splitting half of the tail portion 8003 of the shell body, the split can be performed from the lower half, upper half, left half, or right half of the tail portion 8003 of the shell body.

[0045] In some preferred embodiments, the tail cap 1300 is pre-installed into the tail limiting and fixing groove 80030 via the dovetail groove pre-installation structure 1201 and fixed by the tail cap screw 1400.

[0046] In some preferred embodiments, the tail cap sealing assembly 130 further includes a dust cover 1500; the cable passes through the interior of the dust cover 1500, one end of the dust cover 1500 extends into the limiting through hole 80033 and engages with the tail cap 1300 and the tail limiting fixing groove 80030, and the other end of the dust cover 1500 protrudes from the exterior of the integrated shell body 800 to isolate and seal the interior of the integrated shell body 800 from the exterior. Further, the dust cover 1500 is provided with a first engaging groove 15001 and a second engaging groove 15002, and the dust cover engages with the tail cap 1300 and the tail limiting fixing groove 80030 respectively through the first engaging groove 15001 and the second engaging groove 15002.

[0047] It should be noted that, in this embodiment, since the cable passes through the interior of the dust cover 1500, one end of the dust cover 1500 extends into the limiting through hole 80033 and engages with the tail cover 1300 and the tail limiting fixing groove 80030, while the other end of the dust cover 1500 protrudes from the exterior of the integrated shell body 800. This achieves the separation and sealing of the interior and exterior of the integrated shell body 800 through the dust cover 1500, the cable, the limiting through hole 80033, and the tail limiting fixing groove 80030, as well as their connection and positional relationships, thereby protecting the cable from bending.

[0048] In some preferred embodiments, the tail cap sealing assembly 130 further includes a cable sealing sleeve 1200, through which the cable passes. The cable sealing sleeve 1200 is located inside the limiting through hole 80033 and is limitedly connected to the tail cap 1300 and the tail limiting fixing groove 80030 to isolate and seal the interior of the integrated shell body 800 from the exterior. Furthermore, the tail cap 1300 is provided with a control plate limiting part 13001, which is connected to the tail limiting fixing groove 80030.

[0049] It should be noted that, in this embodiment, the cable sealing sleeve 1200 passes through the inside of the cable, and the cable sealing sleeve 1200 is located inside the limiting through hole 80033, and is limitedly connected to the tail cap 1300 and the tail limiting fixing groove 80030. This achieves the isolation and sealing of the inside and outside of the integrated shell body 800 through the cable sealing sleeve 1200, the cable, the limiting through hole 80033, the tail cap 1300 and the tail limiting fixing groove 80030 and their connection and positional relationship, thereby further enhancing the sealing effect.

[0050] In some preferred embodiments, the control board 1600 extends to the tail portion 8003 of the housing body and contacts the cable sealing sleeve 1200. The cable sealing sleeve 1200 limits the control board 1600 and isolates and seals the internal space of the housing containing the control board 1600 from the outside of the integrated housing body 800. Furthermore, the cable sealing sleeve 1200 is made of an elastic material.

[0051] It should be noted that in this embodiment, the cable sealing sleeve 1200 can not only limit and seal the control board 1600, but also the limiting method of the cable sealing sleeve 1200 is flexible, which can play a buffering role during vibration and impact, and protect the control board 1600.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
