TECHNICAL FIELD
[0001] The application belongs to the technical field of batteries, and particularly relates to a sealing member, a battery device and an electric device. BACKGROUND
[0002] With the rise of new energy equipment represented by new energy vehicles, a battery device has become a key power source. For new energy vehicles, cables are more commonly used. The cables may inevitably be arranged at any position of a vehicle body. In particular, a battery device is often arranged at a chassis of the vehicle body. In order to realize input and output of electric current or input and output of signals, cables are also arranged at the chassis of the vehicle body. In addition to connecting the battery device, the cables also connect other functional devices to realize energy transmission or signal transmission.
[0003] Based on the environment in which the chassis of the vehicle body is located, the sealing performance of the cables located at the chassis of the vehicle body becomes particularly important and high when the cables penetrate into or out of the shell of the battery device or other devices.
[0004] In the related art, due to unreasonable assembly of the sealing structure, the sealing is not strict, which affects the sealing effect. CONTENT OF THE UTILITY MODEL
[0005] In view of the above problems, the application provides a sealing member, a battery device and an electric device, which aims to improve the sealing effect of the position where the cable penetrates into or out of the shell of the functional device or functional area.
[0006] To solve the above problems, in a first aspect, an embodiment of the application provides a sealing member, comprising:
[0007] A connecting piece, wherein a first through hole is arranged on the connecting piece;
[0008] A first sealing member, wherein the first sealing member is installed in the first through hole and is in sealing connection with the first through hole, the first sealing member is provided with a second through hole, and the second through hole is used for allowing a functional piece to pass through in a sealed manner; and
[0009] A second sealing member, wherein the second sealing member is arranged on one side of the connecting piece, and the second sealing member is configured to be pressed by an environmental part and the connecting piece to seal a through hole on the environmental part for the functional piece to pass through.
[0010] The effect of the embodiment is that the functional part and the environmental part are not directly sealed, but are sealed by the connecting part, and the sealing effect is better and more stable. If the functional part and the environmental part are directly sealed by a sealing ring, the structure of the sealing ring is not reliable. First, the first sealing part is arranged in the first through hole of the connecting part and is sealed with the first through hole. The first sealing part is constrained in the space of the first through hole and is sealed by radial extrusion, so as to reduce the risk of warping, deviation or even falling of the first sealing part. When the functional part passes through the second through hole of the first sealing part, it is also extruded radially, and the first sealing part is not easy to warp, deviate or even fall due to being arranged in the space of the first through hole. Furthermore, the second sealing part is extruded between the connecting part and the environmental part. Due to the relative extrusion of the connecting part and the environmental part, the sealing effect of the second sealing part is better, and the second sealing part is not easy to warp, deviate or even fall under the extrusion force.
[0011] In one embodiment of the first aspect, the outer peripheral wall of the first sealing part is extruded and sealed with the inner wall of the first through hole.
[0012] The effect of the embodiment is that the sealing form between the first sealing part and the first through hole is provided, the structure is simple and reasonable, the structure of the first sealing part is stable during the sealing extrusion process, and it is more reliable.

[0017] In one embodiment of the first aspect, along the axial direction of the first through hole, the outer peripheral wall of the first sealing part is spaced apart and provided with a plurality of first protrusions.
[0018] The first protrusions of the embodiment are spaced apart from each other, and each first protrusion is an independent sealing system, and the failure of one first protrusion will not affect the other first protrusions. If a whole annular surface is used to seal the inner wall, the sealing effect of the whole annular surface will be affected once a gap is formed between the annular surface and the inner wall.
[0019] In one embodiment of the first aspect, the outer diameter of the first protrusion in the radial direction of the first through hole is greater than or equal to the inner diameter of the first through hole. In this way, the extrusion force can be increased, and the sealing effect can be enhanced.
[0020] In one embodiment of the first aspect, the inner wall of the second through hole is provided with a plurality of annular second protrusions, and the second protrusions are extrusion sealed with the outer surface of the functional member.
[0021] In the embodiment, the annular second protrusions are provided, and the second protrusions are extrusion sealed with the outer surface of the functional member. The protrusion structure can increase the pressure, and the sealing effect can be enhanced.
[0022] In one embodiment of the first aspect, along the axial direction of the second through hole, the inner peripheral wall of the second through hole is spaced apart and provided with a plurality of second protrusions.
[0023] In the embodiment, the inner wall of the second through hole and the outer peripheral wall of the first sealing member have the same form. The second protrusions are relatively extrusion sealed with the outer wall of the functional member, and the sealing effect is the same as the above effect, and the sealing effect is further ensured.
[0024] In one embodiment of the first aspect, the inner diameter of the second protrusion in the radial direction of the second through hole is less than or equal to the outer diameter of the functional member. In this way, the extrusion force can be increased, and the sealing effect can be enhanced.
[0025] In one embodiment of the first aspect, the connecting member is provided with a plurality of first through holes, and the sealing member includes a plurality of first sealing members, and the plurality of first sealing members are one-to-one correspondingly arranged in the plurality of first through holes.
[0026] In the embodiment, the first through holes of the connecting member are a plurality of first through holes, and the first sealing members are one-to-one correspondingly arranged. Each first through hole can pass through the functional member, so the connecting member can pass through a plurality of functional members. When the functional member is a cable, the cable can have a plurality of strands. Therefore, the sealing requirement of the plurality of strands of the cable can be met.
[0027] In one embodiment of the first aspect, the sealing member further includes a limiting member, and the limiting member is used to limit the first sealing member in the first through hole.
[0028] The effect of the embodiment is that the first sealing member is limited in the first through hole, the stability of the first sealing member is increased, and the first sealing member cannot be pulled out from the inside of the first through hole.
[0029] In one embodiment of the first aspect, the limiting member is arranged on at least one side of the first through hole in the axial direction of the first through hole, and the limiting member has a blocking part arranged in the radial direction of the first through hole, which blocks part blocks part or all of the first sealing member arranged in the first through hole in the axial direction of the first through hole.
[0030] The effect of the embodiment is that the provided limiting member has a simple structure, and a protruding blocking part can be provided, and the effect is significant. The limiting member does not block the functional member, but only blocks the first sealing member.
[0031] In one embodiment of the first aspect, the limiting member is a sleeve structure provided with a third through hole for the functional member to pass through, the connecting member includes a barrel, both ends of the barrel are arranged on both sides of the connecting member, the first through hole is an inner hole of the barrel, and an inner diameter of an opening on one side of the sleeve structure is smaller than an inner diameter of the first through hole to limit the first sealing member. The sleeve structure is sleeved on the barrel through the opening on the other side.
[0032] The effect of the embodiment is that the limiting member adopts a sleeve structure, which can limit and block the first sealing member in the annular direction to prevent the first sealing member from being deflected.
[0033] In one embodiment of the first aspect, a first clamping part is arranged on the sleeve structure, a second clamping part is arranged on the barrel, and the sleeve structure is clamped with the second clamping part through the first clamping part to be fixedly connected with the barrel.
[0034] The effect of the embodiment is that the reliability of the connection between the sleeve structure and the barrel is realized, so that the sleeve structure can maintain the limitation of the first sealing member.
[0035] In one embodiment of the first aspect, the second sealing member is an annular member with a shape matched with the edge shape of the connecting member, and the edge of the connecting member is used to cooperate with the environmental component to extrude the second sealing member.
[0036] The effect of the embodiment is that the second sealing member is matched with the edge shape of the connecting member, so that the second sealing member can be maximized, so that it can be extruded through the edge when it is in the edge position around the through hole on the environmental component. The controllability and adjustability are easy to grasp.
[0037] In one embodiment of the first aspect, the second sealing member is clamped with the connecting member.
[0038] The effect of the embodiment is that when the relative position between the connecting piece and the connecting piece is fixed, the position of the second sealing piece does not need to be adjusted when the connecting piece is pressed against the environmental component, which facilitates operation.

The power consumption device can use a power supply system with the battery device 100 disclosed in the present application, which is beneficial to improve the use reliability of the power consumption device.
[0088] The following embodiments take the power consumption device 1000 provided in the embodiments of the present application as a vehicle for example for convenience of description.
[0089] Please refer to Figure 1 , Figure 1 The structure schematic diagram of the vehicle 1000 provided in some embodiments of the present application is shown in FIG. 1. The vehicle 1000 can be a fuel automobile, a gas automobile, or a new energy automobile, and the new energy automobile can be a pure electric automobile, a hybrid electric automobile, or a range extended automobile, etc. The vehicle 1000 is internally provided with the battery device 100, which can be arranged at the bottom, the head, or the tail of the vehicle 1000. The battery device 100 can be used for power supply of the vehicle 1000, for example, the battery device 100 can be used as an operating power supply of the vehicle 1000. The vehicle 1000 can further include a controller 200 and a motor 300, where the controller 200 is used to control the battery device 100 to supply power to the motor 300, for example, to meet the working power demand of the vehicle 1000 during starting, navigation, and driving.
[0090] In some embodiments of the present application, the battery device 100 can not only be used as an operating power supply of the vehicle 1000, but also be used as a driving power supply of the vehicle 1000, to replace or partially replace fuel or natural gas to provide driving power for the vehicle 1000.
[0091] The battery device 100 is used as a power supply device of the vehicle 1000, and is usually arranged at the chassis of the vehicle 1000. The battery device 100 needs to transmit electric energy and signals, and thus needs to be connected with cables for transmitting electric energy or signals. The cables need to be connected to the inside of the battery device 100, i.e., to pass through the shell of the battery device 100, which can be a box of the battery device 100. In addition, the cables also need to be connected to other functional devices, and thus need to pass through the shells of the other functional devices or pass through the shell surrounding the functional area when the single or multiple other functional devices are located in the same area and the area is provided with a shell. When the cables are arranged at the chassis, the environment of the chassis is various, and even involves water, and thus the through hole 301 through which the cables pass through the shell or the shell needs to have a good sealing effect.
[0092] In the related art, a sealing ring is usually used for direct sealing. However, the structure of the sealing ring is not firm, and is prone to loosening or even falling off, which seriously affects the sealing effect.
[0093] To this end, the sealing member 10 is provided in the embodiments of the present application, which is used for sealing the position where the cable passes through the shell or the housing, so as to improve the sealing effect of the cable.
[0094] The battery device 100 is provided in the embodiments of the present application, and the battery device 100 can also include the sealing member 10, so that the cable passing through the shell, i.e., the box of the battery device 100, can have a good sealing effect.
[0095] Meanwhile, the power consuming device is also provided in the embodiments of the present application, and the power consuming device can also include the sealing member 10 or the battery device 100 provided with the sealing member 10, so as to improve the reliability of the battery device 100 and the power consuming device.
[0096] The sealing member 10 provided in the present application will be described in detail in combination with specific embodiments.
[0097] In the embodiments of the present application, please refer to Figures 3-7 The sealing member 10 includes a connecting member 101, a first sealing member 103, and a second sealing member 104.
[0098] The connecting piece 101 is provided with a first through hole 102; a first sealing piece 103 is installed in the first through hole 102 and is in sealing connection with the first through hole 102, the first sealing piece 103 is provided with a second through hole 1035, the second through hole 1035 is used for sealingly passing the functional piece 20; a second sealing piece 104 is arranged on one side of the connecting piece 101, and the second sealing piece 104 is configured to be extruded by the environmental component 30 and the connecting piece 101 to seal the through hole 301 on the environmental component 30 for the functional piece 20 to pass through.
[0099] Specifically, the connecting piece 101 is an auxiliary structure, which can be in the form of a plate or a frame body structure, but the connecting piece 101 only has the first through hole 102 to communicate both sides of the connecting piece 101, the first through hole 102 has a certain length, which can be a hole directly provided on the connecting piece 101 or an inner hole of a cylinder 111 on the connecting piece 101, the first through hole 102 can accommodate the first sealing piece 103, and the first sealing piece 103 is sealingly arranged between the first through hole 102. Therefore, the first sealing piece 103 needs to be provided with a second through hole 1035 for passing the functional piece 20, which can be a cable, various conduits, etc., and the functional piece 20 is sealingly arranged between the second through hole 1035. The second through hole 1035 is a hole provided on the first sealing piece 103.
[0100] The environmental component 30 can be a housing of the battery device 100, a shell of a functional device, or a shell of a functional area, and the functional piece 20 needs to pass through the housing or the shell and needs to be opened on the environmental component 30, the opening is a through hole 301 of the functional piece 20 on the environmental component 30, the sealing member 10 of the embodiment further includes a second sealing piece 104, which is extruded between the connecting piece 101 and the environmental component 30, so in addition to sealing the functional piece 20 and the first sealing piece 103, the first sealing piece 103 and the connecting piece 101, the second sealing piece 104 is arranged around the through hole 301, and the arrangement of the second sealing piece 104 can also seal the connecting piece 101 and the environmental component 30 to seal the through hole 301 of the functional piece 20 on the environmental component 30.
[0101] The advantage of this embodiment is that it does not directly seal the functional component 20 and the environmental component 30, but instead uses multiple seals through the connector 101, resulting in a better and more stable sealing effect. If the functional component 20 and the environmental component 30 were directly sealed using a sealing ring or similar device, the sealing ring structure would be unreliable. First, the first sealing element 103 is disposed inside the first through hole 102 of the connector 101, sealing with the first through hole 102. Because the first sealing element 103 is confined within the space of the first through hole 102, it is sealed by radial compression, thus reducing the risk of the first sealing element 103 warping, shifting, or even falling off. Similarly, when the functional component 20 passes through the second through hole 1035 of the first sealing element 103, it is also subjected to radial compression, and because the first sealing element 103 is within the space of the first through hole 102, it is also less prone to warping, shifting, or falling off. Furthermore, the second seal 104 is pressed between the connector 101 and the environmental component 30. Due to the relative compression between the connector 101 and the environmental component 30, the sealing effect of the second seal 104 is better. Under the pressure, the second seal 104 is less likely to experience local warping, displacement, or even detachment.
[0102] In some embodiments, please refer to Figure 3 , Figure 5 and Figure 6 The outer peripheral wall of the first seal 103 is pressed and sealed against the inner wall of the first through hole 102.
[0103] The shape of the first sealing element 103 is adapted to the shape of the first through hole 102. The first sealing element 103 is installed in the first through hole 102 and its outer peripheral wall is squeezed and sealed with the inner wall of the first through hole 102.
[0104] Specifically, the connector 101 can be plate-shaped, and the first through hole 102 can be a hole directly formed on the connector 101, or it can be the inner hole of the cylindrical body 111 on the connector 101. This provides a corresponding receiving space to accommodate the first sealing element 103, while also allowing the functional element 20 to pass through. Specifically, it can be a circular hole or a circular cylinder. The shape of the first sealing element 103 is adapted to the first through hole 102, so it can be placed inside the first through hole 102, and the sealing degree is uniform in all directions. The outer peripheral wall of the sealing element 103 and the inner wall of the first through hole 102 are sealed by radial compression. The first sealing element 103 can be configured as a columnar structure and has a hole extending along the axial direction, namely the second through hole 1035, for the functional element 20 to pass through.
[0105] The advantage of this embodiment is that it provides a sealing form between the first sealing element 103 and the first through hole 102. The structure is simple and the assembly is reasonable. During the sealing and extrusion process, the structure of the first sealing element 103 is stable and more reliable.
[0106] In some embodiments, referring to Figure 5 and Figure 6 the inner wall of the second through hole 1035 is used to adapt to the extrusion sealing with the functional piece 20.
[0107] The functional piece 20 is extrusion sealed with the inner wall of the second through hole 1035.
[0108] Specifically, the second through hole 1035 is a hole structure arranged on the second sealing piece 104, which can be a circular hole, and the sealing between the functional piece 20 and the inner wall thereof is achieved in the form of radial extrusion when the functional piece 20 passes through, and the sealing is reliable.
[0109] The second through hole 1035 can be axially arranged along the first sealing piece 103, and a plurality of second through holes 1035 can be arranged for the passage of a plurality of functional pieces 20.
[0110] In some embodiments, referring to Figure 5 and Figure 6 the outer peripheral wall of the first sealing piece 103 is provided with a plurality of annular first protrusions 1031, and the first protrusions 1031 are extrusion sealed with the inner peripheral wall of the first through hole 102.
[0111] The annular first protrusions 1031 are arranged in the embodiment, and the first protrusions 1031 are extrusion sealed with the inner wall of the first through hole 102, and the protrusion structure can increase the pressure and can strengthen the sealing effect.
[0112] In some embodiments, a plurality of first protrusions 1031 are arranged on the outer peripheral wall of the first sealing piece 103 in the axial direction of the first through hole 102.
[0113] The first protrusions 1031 are provided in the embodiment and are arranged at intervals, and the first recesses 1032 can be arranged between adjacent first protrusions 1031, and the first protrusions 1031 are sequentially arranged in the axial direction, and a plurality of seals can be formed in the axial direction.
[0114] The outer peripheral wall of the first sealing piece 103 and the inner wall of the first through hole 102 are sealed in the form of extrusion. In order to improve the sealing effect, the specific structure of the outer peripheral wall of the first sealing piece 103 is provided in the embodiment.
[0115] Specifically, the plurality of first protrusions 1031 are flush in the axial direction, and the first recesses 1032 between adjacent first protrusions 1031 are lower than the first protrusions 1031 in the radial direction, i.e., closer to the axis position. Therefore, when sealed with the inner wall of the first through hole 102, the plurality of first protrusions 1031 are extrusion sealed at intervals.
[0116] The effect of the embodiment is that the first protrusions 1031 are sealed with the inner wall, and the sealing effect is better. Each first protrusion 1031 is an independent sealing system, and the failure of one first protrusion 1031 will not affect the other first protrusions 1031. If a whole annular surface is used to seal with the inner wall, the sealing area is relatively large, but once a gap occurs between the annular surface and the inner wall, the sealing effect of the whole annular surface will be affected.
[0117] In some embodiments, the outer diameter of the first protrusion 1031 in the radial direction of the first through hole 102 is greater than or equal to the inner diameter of the first through hole 102. In this way, the extrusion degree can be increased, and the sealing effect can be enhanced.
[0118] In some embodiments, referring to Figure 5 and Figure 6 , the inner wall of the second through hole 1035 is provided with a plurality of annular second protrusions 1033, and the second protrusions 1033 are extruded and sealed with the outer surface of the functional part 20.
[0119] In the embodiment, the annular second protrusions 1033 are provided, and the second protrusions 1033 are extruded and sealed with the outer surface of the functional part 20. The protrusion structure can increase the pressure, and the sealing effect can be enhanced.
[0120] In some embodiments, along the axial direction of the second through hole 1035, the inner peripheral wall of the second through hole 1035 is spaced apart and provided with a plurality of second protrusions 1033.
[0121] Specifically, the inner wall of the second through hole 1035 has a plurality of annular second protrusions 1033 arranged in sequence along the axial direction of the second through hole 1035, and the second recesses 1034 can be arranged between adjacent second protrusions 1033.
[0122] The inner wall of the second through hole 1035 and the outer peripheral wall of the first sealing member 103 adopt the same form, and the plurality of second protrusions 1033 are relatively extruded with the outer wall of the functional part 20. The effect is the same as the above effect, and the sealing effect is further ensured.
[0123] In some embodiments, the inner diameter of the second protrusion 1033 in the radial direction of the second through hole 1035 is less than or equal to the outer diameter of the functional part 20. In this way, the extrusion degree can be increased, and the sealing effect can be enhanced.
[0124] In some embodiments, referring to Figure 5 , the connecting part 101 is provided with a plurality of first through holes 102, the sealing member 10 includes a plurality of first sealing members 103, and the plurality of first sealing members 103 are arranged in the plurality of first through holes 102 one by one.
[0125] Specifically, the first through holes 102 on the connecting piece 101 are multiple, and each of the first through holes 102 is provided with a first sealing piece 103 one by one, each of the first through holes 102 can pass through the functional piece 20, so the connecting piece 101 can pass through multiple functional pieces 20, when the functional piece 20 is a cable, it can have multiple strands, so as to meet the sealing requirement when multiple strands of cables pass through.
[0126] Meanwhile, multiple second through holes 1035 can also be provided on a single first sealing piece 103, that is, multiple functional pieces 20 can also pass through a single first sealing piece 103.
[0127] In some embodiments, the sealing member 10 further comprises a limiting piece for limiting the first sealing piece 103 in the first through hole 102.
[0128] Specifically, the first sealing piece 103 is inside the first through hole 102, and its stability inside needs to be ensured, for example, when the functional piece 20 passes through, the first sealing piece 103 needs to be prevented from moving with the functional piece 20. Therefore, the limiting piece is provided in this embodiment, and the effect is to limit the first sealing piece 103 in the first through hole 102, thereby increasing the stability of the first sealing piece 103 and preventing it from coming out of the inside of the first through hole 102.
[0129] In some embodiments, along the axial direction of the first through hole 102, the limiting piece is arranged on at least one side of the first through hole 102, and the limiting piece has a blocking portion arranged in the radial direction of the first through hole 102, and the blocking portion blocks part or all of the first sealing piece 103 arranged in the first through hole 102 in the axial direction of the first through hole 102.
[0130] Specifically, the limiting piece is arranged on at least one side of the first through hole 102, and the limiting piece has a blocking portion arranged in the radial direction of the first through hole 102, and the blocking portion is used to limit the first sealing piece 103 in the first through hole 102.
[0131] The limiting piece has a blocking portion in the radial direction, that is, the blocking portion can protrude relative to the inner wall of the first through hole 102, and when the limiting piece is arranged on at least one side of the first through hole 102, the limiting piece can block the first sealing piece 103 from moving along the first through hole 102.
[0132] The limiting piece can be a limiting block that protrudes in the radial direction relative to the inner wall of the first through hole 102.
[0133] The effect of this embodiment is that the provided limiting piece has a simple structure, and a protruding blocking portion can achieve a remarkable effect. The limiting piece cannot block the functional piece 20, but can only block the first sealing piece 103.
[0134] In other embodiments, please refer to Figure 3 , Figure 5The limiting piece is a sleeve structure 105 provided with a third through hole for the functional piece 20 to pass through, the connecting piece 101 comprises a barrel 111, both ends of the barrel 111 are located at both sides of the connecting piece 101 respectively, the first through hole 102 is an inner hole of the barrel 111, and the inner diameter of the opening at one side of the sleeve structure 105 is smaller than the inner diameter of the first through hole 102 to limit the first sealing piece 103, and the sleeve structure 105 is sleeved on the barrel 111 through the opening at the other side.
[0135] Please refer to Figure 3 、 Figure 5 The limiting piece is a sleeve structure 105, the sleeve structure 105 is a through structure provided with a third through hole, the inner diameter of the opening at one side of the sleeve structure 105 is smaller than the inner diameter of the first through hole 102 to limit the first sealing piece 103, and the sleeve structure 105 is sleeved on the barrel 111 through the opening at the other side, and the functional piece 20 is also used to pass through the sleeve structure 105.
[0136] Specifically, the sleeve structure 105 is a communication structure with openings at both ends, but the sizes of the openings at both ends are different, and the opening at one side is small, specifically smaller than the inner diameter of the first through hole 102, so that a block is formed in the radial direction, and the first sealing piece 103 can be effectively limited. The sleeve structure 105 can be sleeved with the barrel 111, facilitating disassembly and assembly.
[0137] The effect of the embodiment is that the limiting piece adopts the sleeve structure 105, which can limit and block the first sealing piece 103 in the annular direction, preventing the first sealing piece 103 from being deflected.
[0138] In some embodiments, please refer to Figure 3 、 Figure 5 The sleeve structure 105 is provided with a first clamping part 106, the barrel 111 is provided with a second clamping part 107, and the sleeve structure 105 is clamped with the second clamping part 107 to be fixedly connected with the barrel 111 through the first clamping part 106.
[0139] Specifically, the sleeve structure 105 is connected with the barrel 111, and in order to ensure the reliability after connection, the first clamping part 106 and the second clamping part 107 are arranged. When the two are connected, the first clamping part 106 and the second clamping part 107 can be clamped with each other, preventing the sleeve structure 105 from being separated from the barrel 111 during long-term use.
[0140] The first clamping part 106 can be a ring structure, and the second clamping part 107 can be a protrusion, which can be clamped into the ring structure.
[0141] The effect of the embodiment is that the reliability of the connection between the sleeve structure 105 and the barrel 111 is realized, so that the sleeve structure 105 can limit the first sealing piece 103.
[0142] In some embodiments, referring to Figure 4 , Figure 5 , the second sealing member 104 is a ring-shaped member with a shape adapted to the edge shape of the connecting member 101, and the edge of the connecting member 101 is used to cooperate with the environmental component 30 to extrude the second sealing member 104.
[0143] The second sealing member 104 is ring-shaped, and the shape of the second sealing member 104 is adapted to the edge shape of the connecting member 101, and the edge of the connecting member 101 is used to correspondingly extrude the second sealing member 104.
[0144] Specifically, the second sealing member 104 is extruded between the connecting member 101 and the environmental component 30, and when the shape of the second sealing member 104 is adapted to the edge shape of the connecting member 101, the second sealing member 104 can be extruded by the edge of the connecting member 101, so that the second sealing member 104 can be extruded in the entire ring direction, and the sealing performance of each part in the ring direction is ensured.
[0145] The effect of the embodiment is that the second sealing member 104 is adapted to the edge shape of the connecting member 101, so that the second sealing member 104 can be maximized, and thus can surround the through hole 301 on the environmental component 30 and be extruded by the edge when in the edge position. The controllability and adjustability are easy to grasp.
[0146] In some embodiments, referring to Figure 4 , Figure 5 , the second sealing member 104 is clamped with the connecting member 101.
[0147] The second sealing member 104 is further provided with an assembly structure 108 matched with the structure concave-convex of the connecting member 101 to clamp the connecting member 101 through the assembly structure 108.
[0148] In addition to the sealing function, the second sealing member 104 also needs to be effectively assembled with the connecting member 101, that is, positioned, so that when the relative position between the second sealing member 104 and the connecting member 101 is fixed, the position of the second sealing member 104 does not need to be adjusted when the connecting member 101 is extruded with the environmental component 30, which facilitates operation. The second sealing member 104 can be provided with an assembly structure 108 matched with the structure concave-convex of the connecting member 101, and when matched, the second sealing member 104 is just located at the edge of the connecting member 101, that is, extends along the edge, so as to realize positioning.
[0149] In some embodiments, referring to Figure 3 , Figure 5 , the connecting member 101 is further provided with a connecting hole used to cooperate with a fastener 109 to fasten the connecting member 101 and the environmental component 30.
[0150] Specifically, the fastener 109 can be a bolt, which passes through the connecting hole, and further passes through a hole on the environmental component 30 and is locked with a nut. The bolt fastening form of the embodiment can approach the environmental component 30 as a whole through the connecting piece 101, and the extrusion force can be adjusted by the tightness, and the controllability is good.
[0151] In some embodiments, referring to Figure 4 , Figure 7 , the sealing member 10 further comprises a damping piece 110, which is used to fix the functional piece 20 passing through the connecting piece 101.
[0152] When the functional piece 20 passes through the first sealing piece 103, i.e. passes through the connecting piece 101, and connects the functional device, when the functional piece 20 is a cable, and when the functional device is a driving motor, the driving motor will vibrate during operation, so that the functional piece 20 will vibrate and may affect the sealing effect. Based on this, the embodiment provides the damping piece 110, which can prevent the functional piece 20 from vibrating to a certain extent and reduce the influence on the sealing performance.
[0153] In some embodiments, referring to Figure 4 , Figure 7 , the damping piece 110 is fixed on the connecting piece 101, and the damping piece 110 has an arc surface 1101 for contacting the functional piece 20, and the damping piece 110 is used to cooperate with the binding piece to fix the functional piece 20.
[0154] Specifically, the arc surface 1101 has a certain area, which can be attached to the surface of the functional piece 20. Especially when the functional piece 20 is a cable, the arc surface 1101 is matched with the arc surface of the cable, and the attachment effect is better. When the functional piece 20 is attached to the damping piece 110, the resonance can be reduced to a certain extent, and the binding piece is also used to cooperate, and the damping effect is better.
[0155] The binding piece can be a bandage or a strap.
[0156] In some embodiments, referring to Figure 4 , the surface of the damping piece 110 opposite to the arc surface 1101 is provided with a notch 1102, and the notch 1102 is used for the binding piece to be adapted and embedded.
[0157] The binding piece simultaneously binds the functional piece 20 and the damping piece 110, i.e. simultaneously passes through both of them, and fixes both of them. When passing through the damping piece 110, in order to prevent the binding piece from being dislocated and affecting the binding firmness, the notch 1102 is provided, and the binding piece enters the notch 1102, and the binding piece is bound, and the binding effect is ensured.
[0158] In some embodiments, the first sealing member 103 is any one of a rubber member, a silica gel member or a plastic member, and / or the second sealing member 104 is any one of a rubber member, a silica gel member or a plastic member, and / or the connecting member 101 is any one of a rubber member, a silica gel member or a plastic member.
[0159] The material of the first sealing member 103, the second sealing member 104 and the connecting member 101 can be selected as required.
[0160] The rubber member and the silica gel member are relatively soft, have good sealing effect, and are chemically stable and insulating. The plastic member is also insulating, and has certain strength and hardness, and is suitable for being used as the connecting member 101 of the auxiliary structure.
[0161] In some embodiments, the functional member 20 can be one or more of a cable, a liquid guide tube, an air guide tube, an oil guide tube, a hydraulic tube, a connecting tube and a connecting rod, and the environmental component 30 can include one or more of a functional device housing, a functional area housing, a sheet metal piece and a protective plate.
