Detailed Implementation

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] The following is combined Figures 1-5 The sleeve assembly, pull rope structure, electronic lock assembly, charging equipment, and vehicle according to embodiments of the present invention are described in detail.

[0038] In the embodiments of this application, reference is made to Figure 1 and Figure 2 As shown, the sleeve assembly includes: a sleeve 10, the sleeve 10 having a hollow channel 11; a first seal 20, the first seal 20 being at least partially disposed within the hollow channel 11, the first seal 20 having a first through hole; the first through hole communicating with the hollow channel 11 to be adapted to thread a pull rope 30 through, the pull rope 30 being adapted to connect to an electronic lock 70 for unlocking the electronic lock 70.

[0039] In existing sleeve assemblies, the pull rope and the sleeve are in a gap fit. When the vehicle has experienced rain or snow and has been in a low-temperature environment for a long time, there is a high probability that the melted snow will enter the gap between the pull rope and the sleeve and freeze, causing the pull rope in the sleeve assembly to be unable to extend or retract, which in turn causes the electronic lock's locking and unlocking functions to fail.

[0040] According to the sleeve assembly of this application embodiment, by providing a first sealing element 20 between the sleeve 10 and the pull rope 30, moisture can be prevented from entering through the gap between the pull rope 30 and the sleeve 10. This effectively prevents water from entering the interior of the sleeve 10 under various working conditions, preventing the pull rope 30 and the sleeve 10 from freezing. This avoids the problem of the pull rope 30's unlocking function failing due to water ingress into the sleeve assembly, effectively improving the sealing performance of the sleeve assembly and thus enhancing the sealing performance of the pull rope structure. Furthermore, the sleeve assembly is applicable to all vehicle models, adapts to a wider variety of working conditions, and has a simple structure, facilitating assembly and ensuring the effectiveness of the pull rope 30's emergency unlocking function.

[0041] Optionally, the sleeve 10 is a nylon tube structure with a sheath. The sheath can be a metal and / or plastic spiral sheath. The process of wrapping the nylon tube with a metal and / or plastic spiral sheath can enhance the compressive strength of the sleeve 10.

[0042] Optionally, the first seal 20 is made of rubber. The material of the first seal 20 can be silicone rubber, which has a wide temperature range (-50℃ to 200℃), good flexibility, ozone resistance, UV resistance, and excellent insulation properties.

[0043] In some embodiments of this application, a first protrusion structure is provided on the inner wall of the through hole of the first seal 20 along the radial direction for interference fit with the pull rope 30. The first seal 20 is made of rubber and has a certain amount of compression. When the pull rope 30 is in a stationary state, the interference fit between the first seal 20 and the pull rope 30 can prevent moisture from entering from the gap between the pull rope 30 and the sleeve 10, and the interference fit between the first seal 20 and the pull rope 30 can effectively limit the free movement of the pull rope 30 in the sleeve 10. When the pull rope 30 is connected to the electronic lock 70 through the unlocking plate 60, the interference fit between the first seal 20 and the pull rope 30 can effectively avoid the problem of the pull rope 30 being unable to lock due to winding on one side of the unlocking plate 60. When manual unlocking via a pull cord is required, pulling the cord 30 causes the rubber material of the first seal 20 to deform, maintaining an interference fit with the cord 30 throughout the process. This effectively prevents water from entering the gap between the cord 30 and the sleeve 10, avoiding the cord 30 freezing and preventing the electronic lock 70 from locking. When the electronic lock 70 automatically locks, the cord 30 moves in the opposite direction, and the first seal 20 and cord 30 maintain an interference fit throughout. When the electronic lock is fully closed, the cord 30 will remain stationary again. The first seal 20 and cord 30 maintain an interference fit, and the cord 30 will remain in a fixed position without affecting the automatic locking / unlocking function of the electronic lock 70 until the next emergency manual unlocking function is used. When the electronic lock 70 automatically unlocks, the first seal 20 and cord 30 maintain a stationary interference fit until the next emergency manual unlocking.

[0044] In some embodiments of this application, the first protrusion structure is a multi-level annular protrusion structure. The multi-level annular protrusion structure can be multiple annular protrusion structures spaced apart along the axial direction of the first seal 20, and these multiple annular protrusion structures can be arranged parallel to each other and / or at an angle; alternatively, the multi-level annular protrusion structure can be multiple annular protrusion structures continuously arranged along the axial direction of the first seal 20. The multi-level annular protrusion structure can increase the contact area between the first seal 20 and the pull rope 30, increase the interference fit between the first seal 20 and the pull rope 30, and further improve the sealing performance of the sleeve assembly to meet the sealing requirements under different working conditions.

[0045] In some embodiments of this application, a second protrusion structure is provided on the outer surface of the first seal 20 along the radial direction for interference fit with the sleeve 10. The interference fit between the second protrusion structure on the radially outer side of the first seal 20 and the sleeve 10 enables the first seal 20 to be more reliably mounted on the sleeve 10.

[0046] In some embodiments of this application, the hollow channel 11 includes a first section and a second section, and the first sealing element 20 is disposed within the first section; wherein, along the radial direction of the sleeve 10, the size of the first section is larger than the size of the second section. The hollow channel 11 in the sleeve 10 can provide a positioning reference for the first sealing element 20, ensuring the accurate installation position of the first sealing element 20 within the sleeve 10 and improving the sealing reliability of the first sealing element 20.

[0047] In some embodiments of this application, a stepped surface 12 is formed at the connection between the first hole segment and the second hole segment, and one end of the first seal 20 abuts against the stepped surface 12. The hollow channel 11 is configured as a stepped hole, which can provide a positioning reference for the first seal 20, and the stepped surface 12 can limit one end of the first seal 20, ensuring that the installation position of the first seal 20 in the sleeve 10 is accurate, and further improving the sealing reliability of the first seal 20.

[0048] In some embodiments of this application, the sleeve assembly further includes a first mounting member 40, which is disposed within the sleeve 10. The first mounting member 40 has a second through hole through which a pull rope 30 can pass. The other end of the first sealing member 20 abuts against the first mounting member 40. The first mounting member 40 achieves omnidirectional unlocking through its cooperation with the sleeve 10. The first sealing member 20 passes through the pull rope 30 along a first direction and is installed between the first mounting member 40 and the stepped surface 12 of the sleeve 10. The first mounting member 40 can guide and position the pull rope 30, and at the same time, it can support and limit the other end of the first sealing member 20, thereby improving the sealing reliability of the first sealing member 20 and the overall structural stability of the sleeve assembly. The first direction is the direction extending along the sleeve 10.

[0049] Therefore, the pull cord 30 is threaded through the first mounting component 40, the first sealing component 20, and the sleeve 10. The pull cord 30 directly bears the pulling force of manual unlocking and the frictional force with the first mounting component 40, the first sealing component 20, and the sleeve 10. Therefore, the material of the pull cord 30 should be tough and resistant to bending, and able to adapt to various bending and winding environments. The pull cord 30 should also have high plasticity, quickly recovering its shape without deformation after bending and pulling, without affecting subsequent use. Due to the waterproof structure design of the first sealing component 20, the surface of the pull cord 30 should also be smoother, reducing friction with mating components, reducing the operating force of the electronic lock 70, and further improving the service life of the electronic lock 70.

[0050] In some embodiments of this application, the sleeve 10 includes a first snap-fit ​​portion 13, and the first mounting member 40 includes a mounting portion 41 and a second snap-fit ​​portion 42. The first snap-fit ​​portion 13 and the second snap-fit ​​portion 42 engage in a snap-fit ​​relationship, and the other end of the first sealing member 20 abuts against the second snap-fit ​​portion 42. The mounting portion 41 guides the pull rope 30, and the second snap-fit ​​portion 42 secures the sleeve 10 and limits the other end of the first sealing member 20. The engagement between the second snap-fit ​​portion 42 of the first mounting member 40 and the first snap-fit ​​portion 13 of the sleeve 10 prevents the first mounting member 40 from detaching from the sleeve 10, improves the tightness of the connection between the first mounting member 40 and the sleeve 10, and ensures the sealing performance of the first sealing member 20. Simultaneously, it enables rapid assembly of the first mounting member 40 and the sleeve 10, improving the installation efficiency of the sleeve assembly.

[0051] In some embodiments of this application, the first snap-fit ​​portion 13 includes at least one snap-fit ​​groove, and the second snap-fit ​​portion 42 includes at least one latch; and / or, the first snap-fit ​​portion 13 includes at least one latch, and the second snap-fit ​​portion 42 includes at least one snap-fit ​​groove. The first snap-fit ​​portion 13 and the second snap-fit ​​portion 42, through the mating structure of the snap-fit ​​groove and the latch, can form a reliable mechanical connection between them, preventing the components from loosening. Optionally, the first snap-fit ​​portion 13 is an annular snap-fit ​​groove or two snap-fit ​​grooves, and the second snap-fit ​​portion 42 includes two latches. The second snap-fit ​​portion 42 can press against the first seal 20 through the latches, preventing the first mounting portion 40 from dislodging from the sleeve 10.

[0052] In some embodiments of this application, the interior of the first mounting member 40 has a stepped hollow structure. Along the radial direction of the sleeve 10, the through-hole size of the mounting portion 41 is smaller than the through-hole size of the second snap-fit ​​portion 42. The interior of the mounting portion 41 allows only the pull rope 30 to pass through without any friction. The side of the second snap-fit ​​portion 42 away from the mounting portion 41 abuts against the first seal 20. Through the stepped hollow design, the mounting portion 41 of the first mounting member 40 can form a limiting structure, preventing the pull rope 30 from shifting during movement and improving guiding accuracy; the second snap-fit ​​portion 42 facilitates snap-fit ​​installation and disassembly. Optionally, the interior of the first mounting member 40 has a stepped cylindrical hollow structure, the outer diameter of the pull rope 30 is 1.2±0.3mm, the internal dimension (i.e., inner diameter) of the mounting portion 41 is 2±0.4mm, and the internal dimension (i.e., inner diameter) of the second snap-fit ​​portion 42 is 4.1±0.5mm.

[0053] In some embodiments of this application, the sleeve assembly further includes a second seal, which is installed within the hollow channel 11 on the side away from the electronic lock 70. Installing the second seal within the hollow channel 11 on the side away from the electronic lock 70 allows the second seal and the first seal 20 to form a double-sealing structure, further improving the sealing performance of the sleeve assembly and preventing water from entering from the sleeve 10 and pull rope 30 on the side away from the electronic lock 70. Optionally, the second seal can be a sealing ring, a rubber sleeve, a corrugated tube, or other sealing structures made of rubber.

[0054] According to the rope structure of the second aspect embodiment of this application, referring to... Figure 1 and Figure 2 As shown, the pull rope structure includes the aforementioned sleeve assembly and pull rope 30. The pull rope 30 passes through the hollow channel 11 of the sleeve 10 and the first through hole of the first seal 20. The pull rope 30 is adapted to connect to the electronic lock 70 for unlocking the electronic lock 70.

[0055] In the existing pull rope structure, the pull rope and the sleeve are in a gap fit. When the vehicle has experienced rain or snow and has been in a low temperature environment for a long time, there is a high probability that the melted snow will enter the gap between the pull rope and the sleeve and freeze, which will cause the pull rope of the pull rope structure to be unable to extend or retract, and thus cause the electronic lock's locking and unlocking functions to fail.

[0056] According to the pull rope structure of this application embodiment, by providing a first sealing element 20 between the pull rope 30 and the sleeve 10, moisture can be prevented from entering through the gap between the pull rope 30 and the sleeve 10. This can effectively prevent water from entering the inside of the sleeve 10 under various working conditions and prevent the pull rope 30 and the sleeve 10 from freezing. This avoids the problem of water entering the pull rope structure causing the unlocking function of the electronic lock to fail, effectively improving the sealing performance of the pull rope structure. At the same time, the pull rope structure is applicable to all vehicle models, adapts to more diverse working conditions, and has a simple structure that is easy to assemble, while ensuring the effectiveness of the unlocking function of the electronic lock 70.

[0057] Optionally, the pull rope 30 is a composite steel wire rope. For example, the pull rope 30 has an internal steel wire rope structure and an external polyurethane coating. The steel wire rope structure is made of multiple strands of stainless steel wire twisted together, which can improve the strength and rust resistance of the pull rope 30. The external polyurethane coating of the steel wire rope structure can enhance the oil resistance, weather resistance and chemical stability of the pull rope 30, making the pull rope 30 suitable for harsh environments.

[0058] In some embodiments of this application, the pull cord structure further includes a second mounting member 50, in which the sleeve 10 is installed. The second mounting member 50 is adapted to be fixedly mounted on the electronic lock 70. The second mounting member 50 ensures that the direction of the force transmitted from the pull cord 30 to the electronic lock 70 is consistent, effectively solving the problem of multi-angle unlocking failure of the pull cord structure. The second mounting member 50 serves as a support structure for the fixed mounting of the electronic lock 70. It can be an additional mounting structure or an integral part of the vehicle's mounting structure. The specific structure and position can be adjusted according to the actual usage and layout requirements of the vehicle.

[0059] In some embodiments of this application, the second mounting component 50 includes a snap-fit ​​ring 51, in which the sleeve 10 is installed, with the snap-fit ​​ring 51 and the sleeve 10 having an interference fit. The direction of the snap-fit ​​ring 51 can be adjusted according to the direction of the pull rope 30 in the pull rope structure, making the pull rope 30 as straight as possible to facilitate unlocking of the electronic lock 70. The interference fit between the snap-fit ​​ring 51 and the sleeve 10 of the second mounting component 50 ensures reliable installation, and the inner diameter of the snap-fit ​​ring 51 matches the outer diameter of the sleeve 10.

[0060] In some embodiments of this application, the snap-fit ​​ring 51 includes an opening with an angle less than 180°. The opening in the snap-fit ​​ring 51 provides it with elastic deformation capability, allowing it to be easily fitted onto the sleeve 10 during installation while maintaining sufficient clamping force to ensure reliable connection. The opening angle of less than 180° ensures that the sleeve 10 is not easily dislodged from the snap-fit ​​ring 51 while maintaining clamping force. Optionally, the snap-fit ​​ring 51 can be secured with cable ties or other fasteners after the sleeve 10 is assembled to further reduce the risk of the sleeve 10 dislodging.

[0061] In some embodiments of this application, the pull cord structure further includes an unlocking plate 60, which is fixedly connected to the pull cord 30. The unlocking plate 60 is used to unlock the electronic lock 70 under the tension of the pull cord 30. The unlocking plate 60 is adapted to connect to the electronic lock 70 so that it unlocks the electronic lock 70 under the tension of the pull cord 30. Adding an unlocking plate 60 to the outside of the electronic lock 70, and connecting it to the electronic lock 70 to unlock the electronic lock 70 under the tension of the pull cord 30, significantly reduces the space required in the first direction.

[0062] In some embodiments of this application, the pull cord 30 is fixedly connected to the unlocking plate 60 via a fastener. The pull cord 30 can be directly bent and fixedly connected to the unlocking plate 60, or it can be fixedly connected to the unlocking plate 60 via a fastener, so that during the manual unlocking process of the electronic lock 70, pulling the pull cord 30 will drive the unlocking plate 60 to complete the unlocking operation of the electronic lock 70. The fastener ensures a rigid connection between the pull cord 30 and the unlocking plate 60, guaranteeing efficient force transmission and preventing unlocking failure due to loosening of the pull cord 30. Furthermore, due to the cooperative arrangement of the unlocking plate 60 and the second mounting member 50, the second mounting member 50 ensures that the direction of the force transmitted from the pull cord 30 to the unlocking plate 60 is consistent, thereby effectively solving the problem of multi-angle unlocking failure in the pull cord structure. Optionally, the fastener is a metal ring or metal block, which is used to press the pull cord 30 against the fastener to fix it to the unlocking plate 60.

[0063] In some embodiments of this application, the unlocking plate 60 is provided with a first hole 61, which is adapted to connect with the transmission mechanism of the electronic lock 70. The unlocking plate 60 is irregularly shaped, and its main body may be a horizontal plate structure. The first hole 61 is provided on the horizontal plate structure of the unlocking plate 60 (e.g., at the center of the horizontal plate structure). The first hole 61 is connected to the transmission mechanism of the electronic lock 70. The transmission mechanism of the electronic lock 70 can transmit the unlocking or locking action of the unlocking plate 60 or the drive mechanism 74 of the electronic lock 70, pushing the latch 73 of the electronic lock 70 to extend or retract, thereby realizing the locking or unlocking of the electronic lock 70 during vehicle charging. Optionally, the first hole 61 is a square hole, and the rotating shaft 71 of the transmission mechanism can be fixedly connected to the square hole of the unlocking plate 60.

[0064] In some embodiments of this application, the unlocking plate 60 has a raised flat plate structure on the side away from the first hole 61. The plane of the raised flat plate structure is set at an angle to the plane of the horizontal plate structure, such as being set vertically. A second hole is opened on the raised flat plate structure of the unlocking plate 60 (e.g., at the center of the raised flat plate structure), and the second hole is the fixing point of the pull rope 30 on the unlocking plate 60.

[0065] It should be noted that the size of the second hole, the strength of the raised plate structure, and the distance between the second hole and the first hole 61 must all meet the locking and unlocking force requirements of the electronic lock 70. If the second hole is too large or the strength of the raised plate structure is insufficient, the fixing part of the pull rope 30 may be pulled out, causing the manual unlocking function to fail. The greater the distance between the second hole and the first hole 61, the greater the manual unlocking stroke, the better the manual unlocking force, and the better the subjective feeling of unlocking. However, at the same time, the locking force of the electronic lock 70 will increase due to the increased locking stroke, putting greater pressure on the internal transmission mechanism of the electronic lock 70 and reducing the service life of the electronic lock 70. Therefore, the distance between the second hole and the first hole 61 should be adjusted according to the manual operation stroke requirements and the structure of the transmission mechanism.

[0066] In some embodiments of this application, the unlocking plate 60, the second mounting member 50, and / or the first mounting member 40 are made of plastic. The unlocking plate 60, the second mounting member 50, and / or the first mounting member 40 can be integrally molded using an injection molding process, which can ensure high strength and corrosion resistance, and has a long service life.

[0067] The electronic lock assembly according to the third aspect of this application, referring to... Figures 3 to 5 As shown, the electronic lock assembly includes an electronic lock 70 and the aforementioned pull cord structure. The pull cord 30 of the pull cord structure is connected to the electronic lock 70 and is used to unlock the electronic lock 70. The electronic lock assembly is compatible with all standard charging ports (including but not limited to Chinese standard DC charging ports, AC charging ports, European standard CCS1 / CCS2 charging ports, and Japanese standard fast charging ports).

[0068] The electronic lock 70 achieves IP67 waterproof rating through an integrated welding process. The pull cord structure connected to the electronic lock 70, through the first sealing element 20 installed in the sleeve 10, achieves both internal and external sealing of the electronic lock 70, thus realizing comprehensive waterproofing of the electronic lock components. This avoids the problem of the electronic lock 70 failing to lock due to water ingress and freezing, effectively improving the safety and reliability of the vehicle.

[0069] According to the embodiments of this application, the electronic lock assembly can achieve external sealing of the electronic lock 70 by providing a first sealing element 20 between the pull rope 30 and the sleeve 10. This can prevent moisture from entering through the gap between the pull rope 30 and the sleeve 10, effectively preventing water from entering the sleeve 10 under various working conditions, preventing the pull rope 30 and the sleeve 10 from freezing, thereby avoiding the problem of water entering the pull rope structure and causing the unlocking function of the electronic lock to fail. This effectively improves the sealing performance of the electronic lock assembly and ensures the effectiveness of the unlocking function of the electronic lock 70.
