[0040] See also Figures 1 to 9 The embodiment of the present application provides a wire outlet waterproof component for a wire-carrying device, the wire-carrying device comprising a shell 10 and a wire 20, the shell 10 being provided with a wire outlet, the wire 20 being inserted into the wire outlet, the wire outlet waterproof component comprising: a fixing seat 100, the corresponding wire outlet being provided in the shell 10; a wire passing assembly 200, provided at a side of the fixing seat 100 away from the wire outlet, so as to enclose with the fixing seat 100 and the corresponding shell 10 to form a waterproof cavity 101, the wire passing assembly 200 being provided with a first wiring hole for the wire 20 to pass through, the wire 20 sequentially passing through the first wiring hole, the waterproof cavity 101 and the wire outlet, and extending out of the shell 10; and a first waterproof component (not shown in the figure), wrapped around the wire 20 corresponding to the waterproof cavity 101, and connected to the inner wall of the waterproof cavity 101.

[0041] In this embodiment, the fixing seat 100 and the wire-passing assembly 200 are arranged inside the shell 10 to increase the contact area between the wire 20 and the waterproof assembly of the wire outlet at least in the routing direction, enhance the restraint on the end of the wire 20, and thus enhance the connection tightness between the wire 20 and the inside of the shell 10; at the same time, the first waterproof component is arranged in the waterproof cavity 101 formed by the inner wall of the shell 10, the fixing seat 100 and the wire-passing assembly 200. On the one hand, the first waterproof component can enhance the compression and fixation of the wire 20, further enhance the connection firmness between the wire 20 inside the shell 10 and the waterproof assembly of the wire outlet; on the other hand, the first waterproof component can enhance the sealing between the wire 20 and the fixing seat 100 and the wire-passing assembly 200, and between the wire 20 and the wire outlet, and enhance the waterproof performance between the wire 20 and the wire outlet of the shell 10. In addition, the wire outlet waterproof component is used to seal and waterproof the wire 20 and the shell 10 inside the shell 10, avoiding the process of gluing and sealing the outside of the wire outlet of the shell 10 in the traditional wire 20 docking method, thereby greatly improving the aesthetics of the connection between the wire 20 and the shell 10.

[0042] Specifically, the outlet waterproof assembly is configured as a composite component including at least a fixing seat 100, a wire passing assembly 200 and a first waterproof component. The fixing seat 100 can be a semi-box-shaped structure, one end of which can be connected to the inner wall of the shell 10 by welding or bonding, and the other end extends toward the center of the shell 10; the top of the fixing seat 100 can be open and share a top cover 12 with the shell 10 to cover the fixing seat 100; a separate top cover can also be provided on the top of the fixing seat 100 to seal the waterproof cavity 101, so as to ensure that the independence and integrity of the entire outlet waterproof assembly are maintained, and reduce the influence of the shell 10 on the waterproof performance of the outlet waterproof assembly. The wire passing component 200 can be a plate-like structure, which is configured on the fixing seat 100 and constitutes a part of the waterproof cavity 101; a first wiring hole is provided on the wire passing component 200 for the wire 20 to pass through, and a plurality of first wiring holes can be provided, and the plurality of first wiring holes are arranged at intervals along the length direction Y of the wire passing component 200, and each first wiring hole can allow at least one wire to pass through; it should be understood that the shape and size of the first wiring hole are adapted to the shape and size of each wire in the wire 20, so that the wire can pass through the first wiring hole smoothly. The first waterproof component can be a glue point filled in the waterproof cavity 101, which has at least two states, namely a flowing state and a fixed state. In the flowing state, the glue point can flow freely to fill the entire waterproof cavity 101, so as to achieve large-area adhesion of the wire 20 in the waterproof cavity 101. At the same time, the glue point can also flow freely to fill the gap between the fixing seat 100 and the shell 10, the gap between the wire 20 and the shell 10, the gap between the wire 20 and the wire passing component 200, and the gap between the fixing seat 100 and the wire passing component 200, so as to achieve the sealing of the gap of the outlet waterproof component and improve the waterproof performance between the wire 20; in the fixed state, the glue point solidifies into a glue layer and no longer flows, which can further fix the wire 20 in the waterproof cavity 101 and ensure that the routing of the wire 20 in the waterproof cavity 101 is fixed and orderly, and will not cause a short circuit due to the movement of the wire 20.

[0043] Of course, in other embodiments, the first waterproof member can also be a waterproof foam inserted into the waterproof cavity 101, in which case the wire 20 in the waterproof cavity 101 is plugged into the waterproof foam. Alternatively, the first waterproof member can also be a rubber member with a fixed shape, which is interference-fitted into the waterproof cavity 101 to achieve the waterproof sealing function of the waterproof component. In this case, the wire 20 in the waterproof cavity 101 can be plugged into the via hole of the rubber member, and then the wire 20 is glued to the via hole by adhesive or the like.

[0044] It should be noted that the wired device mentioned in this embodiment can be a wired battery pack, a wired charging head, a wired mouse, a wired refrigerator / air conditioner, etc., and is not limited to the use scenario of the outlet waterproof component provided in this application.

[0045] In a possible implementation, the wire passing assembly 200 includes a limit member 210 and a sealing member 220 . The limit member 210 is fixed to the fixing seat 100 , and the sealing member 220 is movably disposed above the limit member 210 corresponding to the limit member 210 .

[0046] In this embodiment, the specific configuration of the wire passing assembly 200 is optimized. Specifically, the wire passing assembly 200 is configured as a combined component including at least a stopper 210 and a sealing member 220. The stopper 210 can be a plate-like structure, which can be connected to the side of the fixing seat 100 away from the wire outlet by means of gluing or welding; at the same time, the height of the stopper 210 does not exceed the height of the fixing seat 100, so as to reserve a wire shaping gap above the stopper 210, so that the operator can adjust the wiring arrangement of the wire 20, regularize the wire 20, avoid short circuits caused by chaotic knotting of the wire 20, and improve the safety of the use of the wire 20. The seal 220 may be a plate-like structure, which may be detachably connected to the upper part of the limiter 210 by bonding or other means, and is used to seal the wire shaping notch and improve the sealing performance of the limiter 210 side; it should be explained that the top of the seal 220 is flush with the top of the fixing seat 100, so as to cooperate with the top cover 12 of the housing 10 or the top cover of the fixing seat 100 to form a closed waterproof cavity 101. In this way, the wire assembly 200 arranged in a split manner can facilitate the routing of wires while ensuring the sealing and waterproof performance of the wire assembly 200, thereby improving the safety of the wire 20.

[0047] In addition, the characteristic of the first waterproof component having two different forms can be utilized to allow the first waterproof component in a flowing state to penetrate into the connecting gap between the limiting component 210 and the sealing component 220. After the first waterproof component solidifies, a waterproof layer is formed in the gap between the limiting component 210 and the sealing component 220. In this way, the connection tightness between the limiting component 210 and the sealing component 220 can be further improved, thereby improving the sealing and waterproof properties of the wire-passing assembly 200.

[0048] In one example, the first wire passing hole on the wire passing assembly 200 can be set on the limit member 210. At this time, the wire 20 passing through the limit member 210 can be arranged into a bundle through the wire shaping notch above the limit member 210. After the wire bundle is arranged, the seal 220 is connected to the top of the limit member 210 to seal the wire shaping notch above it.

[0049] Of course, in other embodiments, the first wire-passing hole on the wire-passing assembly 200 can also be set on the sealing member 220. In this case, the wire harness can be first passed through the sealing member 220 to facilitate wiring; and then the sealing member 220 is connected to the upper part of the stopper 210 to form a closed waterproof cavity 101 between the fixing seat 100 and the wire-passing assembly 200. Alternatively, the first wire-passing hole on the wire-passing assembly 200 can also be set between the stopper 210 and the sealing member 220 at the same time, and the operator can choose according to actual needs.

[0050] In one possible embodiment, the sealing member 220 includes a first through-hole portion 221, a first connecting portion 222 and a second through-hole portion 223. The first through-hole portion 221 and the second through-hole portion 223 are respectively arranged on opposite sides of the first connecting portion 222. The first through-hole portion 221 and the second through-hole portion 223 extend out of the first connecting portion 222 in the height direction Z of the wire-passing assembly 200 to form an installation groove 201 in the length direction Y of the wire-passing assembly 200. The sealing member 220 is clamped to the limit member 210 through the installation groove 201.

[0051] In this embodiment, the specific configuration of the sealing member 220 is optimized. Specifically, the sealing member 220 is configured as a composite member including at least a first through-hole portion 221, a first connecting portion 222 and a second through-hole portion 223. The first through-hole portion 221 may be a long plate-shaped structure, the first connecting portion 222 may be a long columnar structure, the second through-hole portion 223 may be a long plate-shaped structure, and the size of the second through-hole portion 223 is equivalent to that of the first through-hole portion 221. The first through-hole portion 221 and the second through-hole portion 223 are arranged on the same side of the first connecting portion 222 and extend in the same direction to enclose with the first connecting portion 222 to form a U-shaped mounting groove. The groove depth of the U-shaped mounting groove is equivalent to the height of the stopper 210, and the groove width and groove length are equivalent to the width and length of the stopper 210. In this way, the U-shaped mounting groove can be sleeved outside the stopper 210 to achieve the connection and fastening of the sealing member 220 and the stopper 210. At the same time, the first through hole portion 221 and the second through hole portion 223 also have a certain guiding function, which is conducive to sleeve-fitting the sealing member 220 onto the limiting member 210 .

[0052] In addition, according to the seal 220 structure provided in this embodiment, at least three sealing layers can be formed in the routing direction of the wire 20 to further improve the sealing performance of the wire passing assembly 200.

[0053] In one possible implementation, a first via hole (not shown) is provided on the first via hole portion 221, an avoidance hole is provided on the first connecting portion 222, and a second via hole is provided on the second via hole portion 223. The first via hole, the avoidance hole and the second via hole are connected to form a first routing hole.

[0054] In this embodiment, the specific configuration of the seal 220 is further optimized. Specifically, the first wiring hole is completely configured on the seal 220. At this time, the first via hole can be a circular hole or a hole of other shapes, the avoidance hole can be a half hole, and the avoidance hole is connected to the mounting groove 201. The second via hole can be a circular hole or a hole of other shapes. The shape of the second via hole is the same as that of the first via hole, so as to take into account the sealing of the connection between the wiring and the wire 20 and the seal 220. In this mode, the first via hole, the avoidance hole and the second via hole can be obtained at the same time by opening a hole on the seal 220, which is convenient for processing and low in production cost.

[0055] In a possible implementation manner, a first half hole 202 is provided on the limiting member 210 , a second half hole 203 is provided on the sealing member 220 , and the second half hole 203 and the first half hole 202 are enclosed to form a first wiring hole.

[0056] In this embodiment, the specific configuration of the limiter 210 and the sealer 220 is optimized. Specifically, the first wiring hole is configured on the limiter 210 and the sealer 220 at the same time, so that the second half hole 203 on the sealer 220 is combined with the first half hole 202 on the limiter 210 to form a complete first wiring hole. The first half hole 202 can be a circular half hole, and the second half hole 203 can be a U-shaped half hole with one end passing through. The bottom semicircle of the U-shaped half hole is combined with the first half hole 202 to form a circular through hole; the top square hole of the U-shaped half hole is used to avoid the first half hole 202. This mode can make full use of the space of the limiter 210, provide a larger opening space for the first wiring hole, and facilitate wiring.

[0057] In one possible embodiment, the fixing seat 100 includes at least two fixed side bones 110, which are arranged in the shell 10, and the two fixed side bones 110 are arranged at opposite sides of the wire outlet at intervals along the length direction Y of the wire passing assembly 200, and the two ends of the wire passing assembly 200 are respectively connected to the two fixed side bones 110.

[0058] In this embodiment, the specific configuration of the fixing seat 100 is optimized. Specifically, the fixing seat 100 is configured as a composite component including at least two fixed side bones 110. The fixed side bones 110 can be a plate-like structure, which can share a working surface with other components configured inside the housing 10 of the lead-line device. For example, when the lead-line device is a battery pack, a battery module 30 is configured inside the housing 10. Then, the fixed side bones 110 can be directly installed on the top of the battery module 30 by welding or clamping. In this way, the raw materials for preparing the fixing seat 100 can be saved, and the space occupied by the fixing seat 100 can be reduced, which is beneficial to the miniaturized layout of the lead-line device. In addition, when the fixing seat 100 is configured on internal components such as the battery module 30, better support can be provided for the waterproof component of the lead-line port, which is beneficial to improving the stability of the internal structure of the lead-line device.

[0059] In a possible implementation, the fixing seat 100 also includes a base plate 120, the rear end of the base plate 120 is connected to the shell 10 corresponding to the line outlet, the two fixed side bones 110 are respectively arranged above the two side edges of the base plate 120, and the wire passing assembly 200 is arranged above the front end of the base plate 120.

[0060] In this embodiment, the specific configuration of the fixing seat 100 is further optimized. Specifically, the fixing seat 100 is configured as a composite component including at least two fixed side bones 110 and a bottom plate 120. The bottom plate 120 can be a plate-like structure, which can be arranged below the two side bones by welding or bonding. At this time, the rear ends of the two fixed side bones 110 and the rear end of the bottom plate 120 are connected to the periphery of the outlet of the shell 10. The shell 10, the two fixed side bones 110, the bottom plate 120 and the wire passing assembly 200 enclose a waterproof cavity 101. This mode is suitable for situations where there are no internal components of appropriate height inside the wire-carrying device. At this time, it is necessary to ensure the tightness of the connection between the bottom plate 120 and the shell 10. For example, the bottom plate 120 and the shell 10 can be further connected and fastened by fasteners such as screws / bolts to ensure that the fixing seat 100 can be firmly set in the internal space of the shell 10.

[0061] In a possible implementation manner, a second waterproof component 300 is further included. The second waterproof component 300 is sleeved on the wire 20 , and the second waterproof component 300 is embedded in the wire outlet of the housing 10 .

[0062] In this embodiment, the specific configuration of the outlet waterproof assembly is further optimized. Specifically, the outlet waterproof assembly is configured as a composite component including at least a fixing seat 100, a wire passing assembly 200, a first waterproof component, and a second waterproof component 300. The second waterproof component 300 can be a waterproof plug, which is configured at the end of the wire 20 and abuts or is embedded in the outlet of the housing 10 as the end of the wire 20 extends into the housing 10, so as to enhance the sealing performance and waterproof performance of the outer side of the outlet.
