[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0040] Furthermore, the terms “first”, “second”, and “third” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] As attached Figure 1-Figure 4 As shown, the present invention provides a sealing structure for a vehicle lock, the vehicle lock includes a housing 7 and a pin accommodated in the housing, the sealing structure includes a first sealing member arranged on the housing, a second sealing member arranged on one end of the pin, and a flexible connecting sleeve connected to the first sealing member and the second sealing member, wherein the pin can move axially in the sealing structure to extend the other end of the pin out of the housing.

[0043] In this embodiment, the first seal 2 is fixedly arranged in the pin shaft sliding hole of the housing 7, the second seal 4 is fixedly arranged on the pin shaft, and the first seal 2 and the second seal 4 are connected by a flexible connecting sleeve 3. When the pin shaft moves axially, the second seal 4 moves along with the pin shaft. Since the connection between the first seal 2 and the second seal 4 is flexible, the movement of the second seal 4 will not affect the first seal 2, thereby ensuring the sealing between the first seal 2 and the housing 7, and ensuring the sealing between the second seal 4 and the pin shaft. The flexible connecting sleeve 3 enables the first seal 2 and the second seal 4 to be sealed and connected, thereby realizing the sealing between the axially moving housing 7 and the housing 7, ensuring the dryness of the inside of the housing 7, preventing rainwater, dust, etc. in the external environment from entering the housing 7, and improving the overall performance and service life of the vehicle lock.

[0044] In this embodiment, the flexible connecting sleeve 3 is a telescopic structure.

[0045] By setting the telescopic structure, the flexible connecting sleeve 3 can be compressed to the maximum extent, thereby ensuring that the second sealing member 4 can move with the pin shaft, thereby ensuring the overall sealing performance. There are many ways to set the telescopic structure. In this embodiment, the specific setting method is: the axial cross-section of the side wall of the flexible connecting sleeve 3 is a wavy structure, that is, it is set in the form of a bellows.

[0046] By setting it as a wave-shaped structure, the wave shape can be used for maximum compression, thereby increasing the telescopic ratio of the flexible connecting sleeve 3, so that the pin shaft will not be affected by the second sealing member 4 and the flexible connecting sleeve 3 when moving, thereby ensuring the normal movement of the pin shaft and the sealing performance of the shell 7.

[0047] In this embodiment, the height of the wave crest at one end of the wave-shaped structure close to the first sealing member 2 is greater than the height of the wave crest at one end close to the second sealing member 4 .

[0048] That is to say, the diameter of the end of the flexible connecting sleeve 3 close to the first seal 2 is larger than the diameter of the end close to the second seal 4. When the flexible connecting sleeve 3 is extended or retracted, the small end can be inserted into the large end, thereby being compressed more compactly, thereby increasing the movable stroke of the pin shaft.

[0049] In addition, since the first seal 2 mainly utilizes its outer wall to seal with the shell 7, its relatively large volume, and the second seal 4 mainly utilizes its inner wall to seal with the pin shaft, and its volume is relatively small, the two ends of the flexible connecting sleeve 3 are respectively set as the large end and the small end, which are respectively connected to the first seal 2 and the second seal 4, which can increase the strength of the connection and ensure the connection effect and sealing effect.

[0050] It should be pointed out that in this embodiment, the diameters of the two ends of the flexible connecting sleeve 3 are different, and they can also be set to the same diameter, as long as the telescopic stroke can meet the stroke of the pin shaft and ensure the strength and sealing performance of the flexible connecting sleeve 3.

[0051] In another embodiment of the present invention, a sealing groove 1 connected to the housing 7 is provided on the outer wall of the first sealing member 2 .

[0052] That is to say, the first seal 2 is formed into a structure with an I-shaped axial cross-section and an axial through hole, and the sealing groove 1 on the shell 7 can be sealed and connected to the shell 7 to ensure the sealing performance between the shell 7 and the first seal 2, thereby preventing moisture and impurities such as dust in the external environment from entering the shell 7.

[0053] Specifically, the shape of the sealing groove 1 matches the shape of the edge of the shell 7, that is, when the end of the shell 7 that matches the sealing groove 1 is rectangular, the sealing groove 1 is also set to a rectangular groove; when the end of the shell 7 that matches the sealing groove 1 is semicircular, the sealing groove 1 is also set to a semicircular.

[0054] That is to say, the shape of the sealing groove 1 can be many, as long as it can cooperate with the edge of the shell 7, mainly with the shape of the side wall of the pin hole on the shell 7, to ensure the sealing performance of the shell 7.

[0055] In this embodiment, the housing 7 is a one-layer structure, and in this case, there is only one sealing groove 1.

[0056] The number of sealing grooves 1 is set according to the number of layers of the housing 7 or the specific shape of the side wall of the pin hole on the housing 7. It can be as follows Figure 3 and Figure 4 As shown, two sealing grooves 1 are provided, or three sealing grooves 1 may be provided, and the specific number is set according to the specific use environment.

[0057] On the basis of the above embodiment, the axis of the sealing groove 1 is the same as the axis of the first sealing member 2. In this way, it can be effectively ensured that the strength of the first sealing member 2 will not be affected after the sealing groove 1 is set on the first sealing member 2, and it can be ensured that when the pin moves axially, the friction between the pin and the first sealing member 2 is used to generate a relatively balanced outward thrust on the first sealing member 2, and there will not be a situation where one side has a large thrust and the other side has a small thrust, thereby avoiding damage to the first sealing member 2 due to uneven force, and ensuring the force strength and service life of the first sealing member 2.

[0058] On the basis of the above embodiment, in another embodiment of the present application, a chamfer 5 is provided on one side of the opening of the sealing groove 1 close to the second sealing member 4 .

[0059] Such a configuration makes it easy to insert the housing 7 into the sealing groove 1 when the first sealing member 2 is matched with the housing 7, thus ensuring the convenience of assembly. Since the other side of the opening is outside the housing 7, it is configured at a right angle, which can effectively prevent rainwater, dust or other impurities from gathering at the chamfer 5 and then penetrating into the housing 7.

[0060] In this embodiment, the chamfer 5 is provided, and its processing method is relatively simple, and the overall cost is not increased, while the convenience of assembly is ensured.

[0061] It should be pointed out that in the present embodiment, the chamfer 5 is provided on the sealing groove 1 to increase the speed of assembly between the first sealing member 2 and the housing 7, but it is not limited to this arrangement. The sealing groove 1 may also be provided as a trapezoidal groove, and the width of the opening is greater than the width of the groove bottom, so that the housing 7 is easier to assemble with the sealing groove 1. That is to say, no matter what shape the sealing groove 1 is, as long as it can facilitate assembly with the housing 7 and ensure the sealing performance with the housing 7, it will suffice.

[0062] On the basis of the above embodiment, in this embodiment, the chamfer 5 is set as a rounded corner.

[0063] It should be pointed out that in the present embodiment, the chamfer 5 is a rounded corner, but it is not limited to a rounded corner. It can also be other types of chamfers 5, such as a 45°×45° chamfer 5, a 30°×60° chamfer 5, etc. In other words, as long as the chamfer 5 can achieve the convenience of assembly and ensure the sealing performance, it will be sufficient.

[0064] On the basis of the basic embodiment, in this embodiment, a sealing strip 6 is provided on the inner wall of the first sealing member 2 in an annular shape around the axis of the first sealing member 2 .

[0065] By arranging a sealing strip 6 on the inside of the first sealing member 2, the pin shaft can be initially sealed, thereby discharging larger particles of impurities outside, and only relatively small amounts of water vapor or dust can enter the outside of the second sealing member 4. Then, through the sealing of the second sealing member 4, all water vapor and dust can be isolated outside the shell 7, thereby ensuring the safety of various components inside the shell 7.

[0066] Specifically, in the present embodiment, a plurality of sealing strips 6 are provided, and the plurality of sealing strips 6 are arranged in parallel. The sealing strip 6 is arranged in an annular shape, and the axis thereof is coaxial with the axis of the first sealing member 2 .

[0067] Such an arrangement can perform multi-stage filtering and sealing on the outer wall of the pin shaft, thereby ensuring the sealing performance and waterproof effect.

[0068] In this embodiment, the cross section of the sealing strip 6 is semicircular. Such a shape will not affect the insertion or extraction of the pin, and the friction between the sealing strip and the pin is small, thereby ensuring the stability of the pin when moving.

[0069] It should be pointed out that the cross-sectional shape of the sealing strip 6 can be semicircular, but it is not limited to semicircular. It can also be other shapes, such as triangle, etc. That is to say, as long as the sealing strip 6 can achieve preliminary filtering of the pin surface and ensure the normal movement of the pin, it will be fine.

[0070] Based on the basic embodiment of the present application, in this embodiment, the second sealing member 4 is set as a sealing ring. The inner diameter of the sealing ring is slightly smaller than the outer diameter of the pin shaft, so that the sealing ring can be fixed on the pin shaft by tight fit, which can not only fix the sealing ring, but also ensure the sealing of the housing 7.

[0071] It should be pointed out that in the present embodiment, the fixing connection method between the sealing ring and the pin shaft is a tight fit, but it is not limited to the tight fit fixing connection method. It can also be other fixing connection methods, such as bonding, etc. That is to say, as long as the sealing ring can be fixedly set on the pin shaft and the sealing performance between the pin shaft and the sealing ring is guaranteed.

[0072] Based on the basic embodiment of the present application, in this embodiment, one end of the flexible connecting sleeve is arranged on the inner wall of the first seal 2, or on the side of the first seal 2 close to the second seal 4; the other end of the flexible connecting sleeve 3 is arranged on the outer wall of the second seal 4, or on the side of the second seal 4 close to the first seal 2.

[0073] Such a configuration ensures that when the flexible connecting sleeve 3 connects the first seal 2 and the second seal 4, it will not affect the sealing performance between the first seal 2 and the housing 7, nor will it affect the sealing performance between the second seal 4 and the pin shaft, thereby ensuring the sealing and waterproof performance of the entire sealing structure 9.

[0074] Based on the basic embodiment of the present application, in this embodiment, the first seal 2, the second seal 4 and the flexible connection sleeve 3 are integrally arranged. Such an arrangement can ensure the sealing performance between the first seal 2 and the flexible connection sleeve 3, and can also ensure the sealing performance between the second seal 4 and the flexible connection sleeve 3, thereby passing.

[0075] It should be pointed out that, in the present embodiment, the first seal 2, the second seal 4 and the flexible connecting sleeve 3 are integrally arranged, but it is not limited to this arrangement, and it may also be other connection methods, such as bonding, etc. That is to say, as long as the first seal 2 and the flexible connecting sleeve 3 can be sealed and connected, and the second seal 4 and the flexible connecting sleeve 3 can be sealed and connected, it will be sufficient.

[0076] Based on the basic embodiment of the present application, in this embodiment, the material of the first sealing member 2 , the second sealing member 4 and the flexible connecting sleeve 3 is silicone.

[0077] By utilizing the adsorption characteristics of silica gel, the waterproof performance of the sealing structure 9 can be increased.

[0078] It should be pointed out that in the present embodiment, the material used for each component of the sealing structure 9 is silicone, but it is not limited to silicone, it can also be other materials, such as rubber, etc. That is to say, as long as the sealing structure 9 can achieve sealing of the inside of the shell 7 and ensure waterproof performance, it will be fine.

[0079] In a second aspect, the present application provides a vehicle lock, which includes any of the above-mentioned sealing structures 9, such as Figure 5-Figure 8 shown.

[0080] The sealing structure 9 used in the present application can be applied to various fields, such as being applied to a car lock, that is, using a movable lock pin for locking the car as a pin shaft, setting the first sealing member 2 on the housing of the car lock, and setting the second sealing member 4 on the lock pin to achieve sealing of the housing of the car lock. It can also be set on a door lock or other device, and its main function is to achieve sealing of an axially movable pin shaft.

[0081] When using it on a car lock, you can Figure 5 and Figure 6 In the horseshoe lock shown, when it is necessary to open the bayonet 11 so that the locking rod 8 can rotate, the bayonet 11 is driven by the drive motor 10 to move axially toward the inside of the housing 7. At this time, the second seal 4 moves inward following the bayonet 11, the first seal 2 does not move, and the flexible connecting sleeve 3 extends; when it is necessary to lock the locking rod 8, the drive motor 10 rotates, and no force is applied to the bayonet 11. Under the action of the compression spring 12, the bayonet 11 moves axially toward the outside of the housing 7 and enters the lock groove 13 on the locking rod 8. At this time, the first seal 2 does not move, the second seal 4 moves outward following the bayonet 11, and the flexible connecting sleeve 3 is compressed.

[0082] Such a configuration can ensure the stability and service life of components inside the vehicle lock, such as the drive motor 10, the control circuit board and other components.

[0083] In a third aspect, the present application provides a vehicle comprising the above-mentioned vehicle lock.

[0084] The above-mentioned vehicle lock can be applied to many kinds of vehicles, such as being set on bicycles, especially shared bicycles, and can also be set on electric vehicles.

[0085] The sealing structure 9, the vehicle lock and the vehicle provided by the present invention are characterized by fixing the first sealing member 2 on the housing 7, fixing the second sealing member 4 on the pin shaft, and connecting the first sealing member 2 and the second sealing member 4 through a flexible flexible connecting sleeve 3, so that the wear between the inner ring of the first sealing member 2 and the pin shaft does not affect the seal between the second sealing ring and the pin shaft, and the seal between the second sealing member 4 and the pin shaft does not affect the seal between the first sealing member 2 and the housing 7. When the pin shaft moves axially, the flexible connecting sleeve 3 is compressed to ensure the sealing connection relationship between the first sealing member 2 and the second sealing member 4, thereby ensuring the sealing of the housing 7. The present invention has a simple structure, strong practicality, low cost, and is suitable for popularization and application.
