Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a wiper blade connector, a wiper, and a carrier. Background Technology

[0002] Windshield wipers are essential cleaning components on the windshields of automobiles and other vehicles. They are primarily used to remove rainwater, snow, frost, dust, mud, and other debris from the glass surface, ensuring the driver has a clear view in adverse weather and complex road conditions, thereby guaranteeing driving safety. A windshield wiper mainly consists of a wiper arm and a wiper blade. The wiper blade has a connector, and the wiper arm connects to the wiper blade via the connector, allowing the wiper arm to drive the wiper blade in a reciprocating oscillating motion, thus cleaning the windshield.

[0003] Currently, wiper blade connectors typically use plug-in connectors, making it easy to remove and replace the wiper blades. Specifically, for buttonless rotary plug-in connectors, when replacing the wiper blade, simply rotate the wiper blade relative to the wiper arm at a certain angle to release the limiting constraint, and then directly pull the pin on the wiper arm out of the connector to remove the wiper blade. However, precisely because wiper blades are so easily detachable, wiper blade theft is a frequent occurrence. Summary of the Invention

[0004] This application provides a wiper blade connector, a wiper, and a carrier to solve or improve the problem in the related art where the wiper blade is easy to remove but often the wiper blade is stolen.

[0005] In a first aspect, this application provides a wiper blade connector, comprising: A connector body is provided for mounting on a wiper blade, and the connector body is provided with a mounting hole for rotatably connecting with a plug on the wiper arm; A sliding cylinder is sleeved on the plug-in and slidably disposed between the plug-in and the mounting hole. The sliding cylinder has a first position and a second position, and the inner wall of the sliding cylinder is provided with a receiving groove. A locking member is disposed in the receiving groove, and the outer wall of the plug-in member is provided with a limiting groove adapted to the locking member. The locking member is used to engage or disengage with the limiting groove under the drive of the sliding cylinder. In the first position, the locking member engages with the limiting groove to lock the plug-in to the connector body; in the second position, the locking member disengages from the limiting groove to unlock the plug-in from the connector body.

[0006] In one alternative implementation, it further includes: An elastic element is disposed in the mounting hole. One end of the elastic element abuts against the sliding cylinder, and the other end is fixedly disposed. The elastic element is used to give the sliding cylinder a tendency to move toward the first position.

[0007] In one optional embodiment, the end of the sliding cylinder is provided with an annular groove adapted to the elastic element, and one end of the elastic element is inserted into the annular groove.

[0008] In one optional embodiment, the sliding cylinder is made of magnetic metal, and the sliding cylinder is adapted to slide from the first position to the second position under the magnetic attraction of an external magnet; And / or, the locking element is made of magnetic metal.

[0009] In one optional embodiment, the outer wall of the sliding cylinder is provided with at least one first annular rib, and each of the first annular ribs is spaced apart along the axial direction of the sliding cylinder. And / or, the inner wall of the sliding cylinder is provided with at least one second annular rib, and each of the second annular ribs is spaced apart along the axial direction of the sliding cylinder.

[0010] In one optional embodiment, a lubricant is provided between the wall of the mounting hole and the outer wall of the sliding cylinder; And / or, there is a first gap between the wall of the mounting hole and the outer wall of the sliding cylinder; And / or, there is a second gap between the inner wall of the sliding cylinder and the outer wall of the connector.

[0011] In one optional embodiment, the receiving groove is provided radially through the sliding cylinder, and the mounting hole is provided with a tapered hole section. In the first position, one side of the locking member abuts against the tapered hole section, and the other side is engaged with the limiting groove. The diameter of the tapered hole section gradually decreases along the direction in which the sliding cylinder slides from the second position to the first position. And / or, at least two locking members are provided, each of the locking members being circumferentially spaced around the sliding cylinder, and the receiving grooves being provided one-to-one with the locking members.

[0012] In one alternative embodiment, the connector body includes: A connector bracket for connecting to the wiper blade, the connector bracket being provided with the mounting hole; A connector cover is fastened to the connector support, and the connector cover is provided with a clearance opening for the insertion piece to pass through.

[0013] Secondly, this application also provides a windshield wiper, including a wiper blade connector as described in any of the preceding claims.

[0014] Thirdly, this application also provides a carrier, including the windshield wipers as described above.

[0015] The wiper blade connector provided in this application, under normal wiper operation, has the sliding cylinder in the first position, where the sliding cylinder drives the locking element to engage in the limiting groove. At this time, the connector and the main body are locked, preventing the wiper arm from being separated from the wiper blade connector. When the wiper blade needs to be replaced, the wiper blade is first rotated relative to the wiper arm at a certain angle to release the limiting constraint. Then, the sliding cylinder is moved to the second position, causing the sliding cylinder to disengage the locking element from the limiting groove. At this time, the connector and the main body are unlocked, allowing the connector to be pulled out of the wiper blade connector and the wiper blade removed. Furthermore, the sliding cylinder and locking element are concealed inside the wiper blade connector, making them difficult for thieves to detect. Thus, while ensuring the wiper blade is detachable, it effectively provides anti-theft functionality. Attached Figure Description

[0023] The following is combined Figures 1 to 13 This application describes the wiper blade connector 10, wiper, and carrier according to embodiments of the present application.

[0024] According to embodiments of this application, in a first aspect, a wiper blade connector 10 is provided, please refer to [reference needed]. Figures 1 to 4 As shown, the wiper blade connector 10 includes a connector body 1, a sliding cylinder 2, and a locking member 3. Specifically, as... Figure 3 As shown, the connector body 1 is used to mount on the wiper blade 20, for example, the connector body 1 and the wiper blade 20 are snap-fitted together or glued together. Figure 2 and Figure 4 As shown, the connector body 1 is provided with a mounting hole 103 for rotatably connecting with the plug 3001 on the wiper arm 30. Optionally, as Figure 2 and Figure 3 As shown, the end of the wiper arm 30 is provided with a plug 3004, and the side of the plug 3004 is provided with a connector 3001 that mates with the mounting hole 103. For example, the connector 3001 can be a pin, and the connector 3001 is rotatably inserted into the mounting hole 103. Figure 3 The dashed line in the middle shows the rotation axis of the connector 3001.

[0025] It is understandable that the wiper blade 20, as the cleaning component that directly contacts the windshield, has a core component of a rubber strip; the wiper arm 30, as the component connecting the wiper drive mechanism and the wiper blade 20, is mainly responsible for converting the motion of the motor and drive mechanism into the reciprocating wiping motion of the wiper blade 20; the wiper blade connector 10, as the component connecting the wiper blade 20 and the wiper arm 30, is mainly responsible for transmitting the motion of the wiper arm 30 to the wiper blade 20, enabling the wiper blade 20 to perform the wiping motion as required, thus ensuring the normal operation of the wipers. Since the wiper blade 20 is a friction-sensitive wear part, in this embodiment, the wiper blade connector 10 adopts a plug-in connector, specifically a buttonless rotary plug-in connector, thereby facilitating easy disassembly of the wiper blade 20 and enabling quick replacement. In some alternative embodiments, the motor and linkage assembly transmits power to the two wiper arms 30 via the output shaft and spline, driving the two wiper arms 30 to perform reciprocating oscillating motion. The wiper arms 30 are connected to the wiper blades 20 via the wiper blade connectors 10 on the corresponding wiper blades 20, thereby causing the wiper arms 30 to drive the corresponding wiper blades 20 to perform reciprocating oscillating motion synchronously.

[0026] It should be noted that, as Figure 3 As shown, the side of the plug 3004 is also provided with a limiting flange 3003, such as... Figure 3 and Figure 5 As shown, the connector body 1 is provided with a limiting groove 1021 that is adapted to the limiting flange 3003, and the limiting flange 3003 can engage with the limiting groove 1021. In this embodiment, as... Figure 5 As shown, under normal wiper operation, the limiting flange 3003 on the wiper arm 30 and the limiting slot 1021 on the wiper blade connector 10 are engaged. At this time, the wiper blade 20 and wiper arm 30 are in a constrained and locked state, and the wiper blade 20 and wiper arm 30 remain almost parallel. The wiper arm 30 can reliably drive the wiper blade 20 to perform reciprocating oscillating motion, thus cleaning the windshield. When the wiper blade 20 needs to be replaced, as... Figure 1 As shown, the wiper blade 20 is rotated a certain angle relative to the wiper arm 30. At this time, as... Figure 6 As shown, the limiting flange 3003 on the wiper arm 30 is disengaged from the limiting slot 1021 on the wiper blade connector 10. After the limiting constraint is released, the plug 3001 can be pulled out from the wiper blade connector 10, and then the wiper blade 20 can be removed.

[0027] Furthermore, such as Figure 4 and Figure 8 As shown, the sliding cylinder 2 is sleeved on the connector 3001 and slidably positioned between the connector 3001 and the mounting hole 103. Furthermore, as... Figure 8 and Figure 9As shown, the sliding cylinder 2 has a first position and a second position. Specifically, the sliding cylinder 2 slides along the axial direction of the connector 3001 to switch between the first position and the second position. Figure 4 and Figure 11 As shown, the inner wall of the sliding cylinder 2 is provided with a receiving groove 201, and the locking member 3 is disposed within the receiving groove 201. Figure 7 As shown, the outer wall of the connector 3001 is provided with a limiting groove 3002 that matches the locking member 3. Optionally, the locking member 3 is a ball, and the limiting groove 3002 is set as a matching arc-shaped groove. In this way, rolling friction is formed between the ball and the arc-shaped groove, which can reduce frictional resistance, make the movement smoother and less effortless, and eliminate jamming or stuttering, greatly improving the operation feel and convenience. In addition, the arc-shaped groove has a high degree of fit with the spherical curved surface of the ball, which can achieve precise circumferential / radial limiting, and the locking is stable and reliable.

[0028] In this embodiment, the locking member 3 is used to engage or disengage with the limiting groove 3002 under the action of the sliding cylinder 2. Specifically, in the normal operating state of the windshield wiper, such as... Figure 8 As shown, when the sliding cylinder 2 slides to the first position, the sliding cylinder 2 drives the locking member 3 to engage with the limiting groove 3002, thereby locking the plug-in member 3001 to the connector body 1. At this time, the locking member 3 and the limiting groove 3002, as well as the limiting flange 3003 and the limiting slot 1021, work together to ensure that the wiper blade 20 will not come out. When it is necessary to replace the wiper blade 20, first rotate the wiper blade 20 relative to the wiper arm 30 by a certain angle so that the limiting flange 3003 disengages from the limiting slot 1021, and then, as shown... Figure 9 As shown, when the sliding cylinder 2 slides to the second position, the sliding cylinder 2 causes the locking member 3 to disengage from the limiting groove 3002, thereby unlocking the plug-in member 3001 from the connector body 1. At this time, the user can pull out the plug-in member 3001 axially. Thus, compared to traditional buttonless rotary plug-in connectors, this embodiment adds a limiting locking structure composed of the sliding cylinder 2 and the locking member 3 inside the connector body 1. The overall appearance of the connector remains largely unchanged. During the disassembly of the wiper blade 20, this built-in locking structure possesses strong structural concealment. Thieves cannot visually detect the existence of this anti-theft structure from the outside. It is difficult to discover, identify, and break the locking limit during conventional disassembly operations, and cannot be unlocked by conventional means to complete the theft, significantly improving the anti-theft effect. Therefore, without changing the product appearance or affecting normal use, a highly efficient anti-theft system is achieved through a built-in concealed design, effectively preventing the illegal theft of the wiper blade 20. The anti-theft effect is stable and reliable.

[0029] With this configuration, under normal wiper operation, the sliding cylinder 2 is in the first position, and the sliding cylinder 2 drives the locking element 3 to engage in the limiting groove 3002. At this time, the connector 3001 and the connector body 1 are locked, preventing the wiper arm 30 from being separated from the wiper blade connector 10. When it is necessary to replace the wiper blade 20, first rotate the wiper blade 20 relative to the wiper arm 30 by a certain angle to release the limiting constraint, and then move the sliding cylinder 2 to the second position. The sliding cylinder 2 drives the locking element 3 to disengage from the limiting groove 3002. At this time, the connector 3001 and the connector body 1 are unlocked, and the connector 3001 can be pulled out from the wiper blade connector 10 to remove the wiper blade 20. At the same time, the sliding cylinder 2 and the locking element 3 are hidden inside the wiper blade connector 10, making them relatively concealed and difficult for thieves to detect. Thus, while ensuring the detachability of the wiper blade 20, it effectively provides an anti-theft function.

[0030] Optionally, in some embodiments of this application, such as Figure 4 As shown, the wiper blade connector 10 also includes an elastic element 4, which can optionally be a spring. The elastic element 4 is disposed in the mounting hole 103. The mounting hole 103 is a blind hole or a through hole structure, used to provide a stable mounting and guiding space for the elastic element 4. One end of the elastic element 4 abuts against the sliding cylinder 2, and the other end of the elastic element 4 is fixedly disposed. The elastic element 4 is used to give the sliding cylinder 2 a tendency to move toward the first position. Optionally, one end of the elastic element 4 abuts tightly against the corresponding end of the sliding cylinder 2, and the other end is fixedly abutted against the inner wall of the bottom of the mounting hole 103 or the fixing structure inside the connector body 1 to achieve axial positioning and fixation. In its natural state, the elastic element 4 continuously applies a stable elastic pushing force to the sliding cylinder 2, so that the sliding cylinder 2 always has a tendency to move toward the first position.

[0031] In this embodiment, as Figure 8 As shown, under the elastic force of the elastic element 4, the sliding cylinder 2 is stably maintained in the first position, i.e., the locked position. Combined with the locking structure of the locking element 3 and the limiting groove 3002, reliable locking is achieved. Figure 9 As shown, when disassembly and unlocking are required, the operator applies external force to drive the sliding cylinder 2 to overcome the elastic force of the elastic element 4 and move it upwards towards the second position, i.e., the unlocking position, thus causing the locking element 3 to disengage from the limiting groove 3002, completing the unlocking action; when the external force is removed, as shown... Figure 8 As shown, the sliding cylinder 2 can automatically and quickly rebound to the first position and move downward under the elastic reset action of the elastic element 4, thereby causing the locking element 3 to engage again in the limiting groove 3002 and restore the locked state. It should be noted that... Figure 8 and Figure 9 In the middle, the lower single-line arrow indicates the pull-out direction of the connector 3001, and the upper solid arrow indicates the direction of the force on the sliding cylinder 2 and the locking member 3.

[0032] With this configuration, the elastic element 4 continuously provides the sliding cylinder 2 with an elastic preload towards the first position, i.e., the locked position. This effectively prevents the sliding cylinder 2 from accidentally shifting or failing to lock due to vehicle vibration or external force shaking, ensuring a stable and reliable locking state for the wiper blade connector 10. It also prevents the wiper blade 20 from becoming abnormally loose. Furthermore, after unlocking, manual reset is not required; the sliding cylinder 2 automatically resets and locks under the elastic force, significantly simplifying the unlocking and reset process of the wiper blade connector 10, making it more convenient and efficient to use. In addition, the elastic element 4 is embedded inside the mounting hole 103, forming a built-in structure that does not protrude from the outside of the connector body 1, does not change the overall shape of the product, maintains structural concealment, and fully guarantees the anti-theft effect.

[0033] Optionally, in some embodiments of this application, such as Figure 10 As shown, the end of the sliding cylinder 2 is provided with an annular groove 202 that matches the elastic element 4, and one end of the elastic element 4 is inserted into the annular groove 202. It should be noted that the radial dimension and axial groove depth of the annular groove 202 are precisely matched with the end diameter and axial extension length of the elastic element 4, forming a dedicated embedding and positioning structure. The end of the elastic element 4 near the sliding cylinder 2 is coaxially inserted into the annular groove 202, and the circumferential sidewall of the annular groove 202 forms a radial enclosure and limit for the elastic element 4. The end face of the elastic element 4 is tightly fitted and abuts against the bottom of the annular groove 202. In the assembled and working state, the annular groove 202 always constrains the end position of the elastic element 4, keeping the elastic element 4 and the sliding cylinder 2 coaxially arranged. During the reciprocating sliding of the sliding cylinder 2 and the reciprocating extension and retraction of the elastic element 4, this groove structure continuously provides radial limit and guidance for the elastic element 4, ensuring that the elastic element 4 does not tilt, deviate, or come out, and always stably pushes the sliding cylinder 2 axially.

[0034] With this design, the annular groove 202 can provide circumferential and radial dual constraints on the end of the elastic element 4, ensuring that the elastic element 4 and the sliding cylinder 2 are always coaxial. This prevents the elastic element 4 from becoming skewed, twisted, or eccentric during extension and retraction, ensuring stable axial output of elastic force and preventing the sliding cylinder 2 from jamming. Furthermore, the end of the elastic element 4 is embedded in the annular groove 202, and the groove wall forms a physical limit, which can effectively prevent the elastic element 4 from falling off or shifting from the end of the sliding cylinder 2 due to vehicle vibration or long-term reciprocating motion. This ensures the long-term stable operation of the elastic reset structure and eliminates locking failure caused by the elastic element 4 falling off. In addition, it can maintain a compact overall structure without increasing the axial dimension of the sliding cylinder 2, meeting the miniaturization and concealed anti-theft design requirements of the wiper blade connector 10.

[0035] Optionally, in some embodiments of this application, the sliding cylinder 2 is made of magnetic metal, and the sliding cylinder 2 is adapted to slide from a first position to a second position under the magnetic attraction of an external magnet 5. Optionally, the sliding cylinder 2 can be made of materials with excellent magnetic response properties, such as low-carbon steel, pure iron, or iron-based alloys, to ensure that it can efficiently respond to the action of an external magnetic field. It should be noted that, as Figure 8 As shown, under the elastic force of the elastic element 4, the sliding cylinder 2 is stably held in the first position and acts downward on the locking element 3, so that the locking element 3 is tightly engaged with the limiting groove 3002, achieving reliable locking, thus the wiper arm 30, equivalent to the wiper blade 20, cannot be pulled out along the axial direction of the connector 3001. Figure 9 As shown, when disassembly and unlocking are required, the operator can place a dedicated external magnet in the corresponding area outside the wiper blade connector 10. The magnetic field generated by the external magnet 5 can penetrate the connector housing and directly act on the internal magnetic metal sliding cylinder 2, generating a directional magnetic attraction force. Driven by the external magnetic attraction force, the sliding cylinder 2 overcomes the elastic force of the elastic element 4 and slides upward from the first position to the second position along the axial direction of the plug 3001, thereby releasing the limiting constraint of the locking element 3, completing the connector unlocking, and realizing the normal disassembly of the wiper blade 20. When the external magnet 5 is removed, the sliding cylinder 2 automatically returns to the first position from the second position under the reset action of the elastic element 4, restoring the locked state. It should be noted that the sliding cylinder 2 only responds to the directional magnetic attraction force of the dedicated magnet; conventional vibration and external prying cannot cause it to shift, ensuring the long-term stability of the locking structure.

[0036] With this design, the sliding cylinder 2 is unlocked by external magnetic attraction. There is no need to open any operation holes or toggle slots on the outside of the connector. The overall appearance has no unlocking marks. Thieves cannot identify or find the unlocking structure from the outside, and cannot pry it open with conventional tools, thus preventing the wiper blade 20 from being stolen and removed.

[0037] In addition, in some embodiments, besides using the magnetic attraction of a dedicated external magnet 5 to move the sliding cylinder 2 to the unlocked position, a concealed rotating sleeve of the same outer diameter can also be provided on the connector body 1 at the position corresponding to the sliding cylinder 2. The rotating sleeve is flush with the outer wall of the connector body 1, without a handle or slot, and its appearance is integrated with the overall housing. The inner side of the rotating sleeve is provided with a spiral guide groove, and the outer wall of the sliding cylinder 2 is provided with a guide post that matches the spiral guide groove. When the operator pinches the rotating sleeve from the outside and rotates it at a small angle, the spiral guide groove drives the guide post to move axially, thereby causing the sliding cylinder 2 to overcome the elastic force of the elastic element 4 and slide from the first position to the second position. After reversing the rotation or releasing, under the action of the restoring force of the elastic element 4, the sliding cylinder 2 drives the rotating sleeve to automatically rotate back to reset and restore the locked state.

[0038] Optionally, in some embodiments of this application, the locking element 3 is made of a magnetic metal. Optionally, the locking element 3 can be made of materials with excellent magnetic response properties, such as low-carbon steel, pure iron, or iron-based alloys. Thus, as... Figure 9 As shown, when the wiper blade 20 needs to be disassembled and unlocked, the locking part 3 can also generate an upward movement trend under the magnetic attraction of the external magnet 5, thereby further pushing the sliding cylinder 2 upward and assisting in pushing the sliding cylinder 2 to slide upward from the first position to the second position, making the unlocking action of the sliding cylinder 2 smoother and the operation more effortless.

[0039] Optionally, in some embodiments of this application, such as Figure 11 As shown, the outer wall of the sliding cylinder 2 is provided with at least one first annular rib 203, and the first annular ribs 203 are spaced apart along the axial direction of the sliding cylinder 2. It should be noted that the number of first annular ribs 203 can be determined according to actual design requirements, for example, such as... Figure 10 and Figure 11 As shown, four first annular ribs 203 are provided, and each first annular rib 203 is evenly spaced along the axial direction of the sliding cylinder 2. The outer circular surface of the first annular rib 203 forms a sliding mating surface with the inner sidewall of the connector body 1. With this configuration, during the reciprocating sliding of the sliding cylinder 2 between the first and second positions along the axial direction, the sliding cylinder 2 no longer contacts the inner sidewall of the connector body 1 with a large area of ​​its entire outer wall. Instead, it is guided only by the narrow annular surface of the first annular rib 203 fitting against the corresponding mating wall surface, achieving smooth sliding with a small area and low resistance. This effectively avoids sliding jamming between the sliding cylinder 2 and the connector body 1, reduces the friction between them, and extends the service life of the structure.

[0040] Optionally, in some embodiments of this application, such as Figure 11 As shown, the inner wall of the sliding cylinder 2 is provided with at least one second annular rib 204, and the second annular ribs 204 are spaced apart along the axial direction of the sliding cylinder 2. It should be noted that the number of second annular ribs 204 can be determined according to actual design requirements, for example, such as... Figure 8 and Figure 11 As shown, seven second annular ribs 204 are provided, and each second annular rib 204 is evenly spaced along the axial direction of the sliding cylinder 2. The inner circular surface of the second annular rib 204 forms a sliding mating surface with the outer wall of the connector 3001. With this configuration, the second annular ribs 204 change the traditional large-area surface contact to a narrow-ring small-area contact, significantly reducing the frictional resistance between the sliding cylinder 2 and the connector 3001, making the axial sliding of the sliding cylinder 2 easier and smoother, reducing the effort required for operation, and improving the overall service life.

[0041] Optionally, in some embodiments of this application, such as Figure 10As shown, a lubricant is provided between the wall of the mounting hole 103 and the outer wall of the sliding cylinder 2. Optionally, the lubricant can be grease, lubricating oil, or a solid lubricating coating, and the lubricant is evenly distributed between the relative sliding contact surfaces of the mounting hole 103 and the sliding cylinder 2. During the axial reciprocating sliding of the sliding cylinder 2 along the mounting hole 103, a stable lubricating film is continuously formed, ensuring that the sliding cylinder 2 and the wall of the mounting hole 103 are always in a lubricated state, thereby ensuring smooth sliding movement without dry friction or jamming. Specifically, during the assembly process, the lubricant can be directly applied to the inner wall of the mounting hole 103 or the outer wall of the sliding cylinder 2, and then the sliding cylinder 2 is inserted into the mounting hole 103, allowing the lubricant to naturally fill the mating gap; during long-term use, the lubricant can remain stably and continuously play a lubricating role. This setting transforms dry friction into lubricating film friction, significantly reducing sliding resistance, effectively preventing the sliding cylinder 2 from jamming and making abnormal noises, reducing component wear, and extending service life.

[0042] Optionally, in some embodiments of this application, such as Figure 10 As shown, there is a first gap between the wall of the mounting hole 103 and the outer wall of the sliding cylinder 2. This first gap is an annular gap that is evenly distributed circumferentially. The gap size can be reasonably set according to the sliding stroke of the sliding cylinder 2, the machining tolerance, and the vehicle-mounted operating conditions. This provides sufficient space for the axial reciprocating motion of the sliding cylinder 2 while controlling the radial wobble. Optionally, the first gap is greater than 0 and less than or equal to 0.2 mm, for example, it can be 0.05 mm, 0.1 mm, 0.15 mm, or 0.2 mm, or it can be any value between two values. This is only an example and is not a specific limitation.

[0043] Optionally, in some embodiments of this application, such as Figure 8 As shown, there is a second gap between the inner wall of the sliding cylinder 2 and the outer wall of the connector 3001. This second gap is a uniform annular gap, used to avoid friction or compression between the sliding cylinder 2 and the connector 3001 during relative movement. Optionally, the second gap is greater than 0 and less than or equal to 0.2 mm, for example, it can be 0.05 mm, 0.1 mm, 0.15 mm, or 0.2 mm, or any value between two values. This is only an example and no specific limitation is made.

[0044] It should be noted that the first gap and the second gap can be set individually or simultaneously. Together, they provide structural support for the axial sliding of the sliding cylinder 2 between the first and second positions, effectively eliminating movement obstacles caused by assembly deviations, machining errors, and material deformation. In this way, the first gap and the second gap reserve a certain axial movement space for the sliding cylinder 2, structurally preventing scraping or jamming between the mounting hole 103, the connector 3001, and the sliding cylinder 2, ensuring smooth and unobstructed movement of the sliding cylinder 2 during magnetic drive and reset of the elastic element 4. Furthermore, the gap structure effectively absorbs dimensional machining errors and assembly deviations of the components, eliminating the need for ultra-high precision machining, significantly reducing production accuracy requirements and manufacturing costs, and making it more suitable for mass industrial production.

[0045] Optionally, in some embodiments of this application, such as Figure 10 and Figure 11 As shown, the receiving groove 201 is radially through the sliding cylinder 2, thus forming a through channel for the locking member 3 to move radially. The locking member 3 can be freely and movably assembled within the receiving groove 201 and can move radially within and outside the groove along the sliding cylinder 2. Figure 8 and Figure 12 As shown, the mounting hole 103 is provided with a tapered hole section 104. In the first position, one side of the locking member 3 abuts against the tapered hole section 104, and the other side is engaged with the limiting groove 3002. And as... Figure 13 As shown, along the direction of sliding of the sliding cylinder 2 from the second position to the first position, the diameter of the tapered hole section 104 gradually decreases, forming a tapered surface structure that faces the locking position.

[0046] In this embodiment, as Figure 8 As shown, when the sliding cylinder 2 is in the first position under the action of the elastic member 4, the outer spherical surface of the locking member 3 is in close contact with the conical surface of the conical hole section 104 of the mounting hole 103. Under the action of the radial extrusion force of the conical surface, the locking member 3 extends radially into the sliding cylinder 2, and its inner spherical surface forms a stable snap-fit ​​with the limiting groove 3002 on the plug member 3001, thereby locking the wiper blade 20 and the wiper arm 30 together.

[0047] like Figure 9 As shown, when the sliding cylinder 2 slides axially from the first position to the second position under the magnetic attraction of the external magnet 5, the receiving groove 201 moves synchronously with the sliding cylinder 2, and the locking member 3 gradually gets away from the radial constraint of the tapered hole section 104, and can move to the outside of the sliding cylinder 2, thereby releasing the snap-fit ​​relationship with the limiting groove 3002 and completing the unlocking action.

[0048] With this configuration, the conical bore section 104 gradually narrows in diameter towards the locking direction, forming a conical self-locking structure. When the sliding cylinder 2 is in the first position, the conical surface continuously applies radial compressive force to the locking member 3, firmly locking it into the limiting groove 3002, reducing radial movement and gap wobble. Vehicle vibrations and bumps will not cause locking failure, resulting in high locking safety. The conical bore section 104 can automatically apply radial inward pushing force to the locking member 3, achieving automatic locking of the locking member 3 without the need for additional auxiliary components such as compression springs, greatly simplifying the internal structure and improving the reliability of the mechanism. As the sliding cylinder 2 moves towards the unlocking direction, the diameter of the conical surface gradually increases, and the radial constraint of the locking member 3 is slowly released, making the unlocking process smooth and gradual. Combined with magnetic drive, the unlocking action is smoother and the operation is less strenuous.

[0049] Optionally, in some embodiments of this application, such as Figure 10 and Figure 11 As shown, at least two locking members 3 are provided, each locking member 3 is arranged circumferentially around the sliding cylinder 2 at intervals, and the receiving grooves 201 are arranged one-to-one with the locking members 3. Optionally, the locking members 3 can adopt a ball bearing structure, and their number can be determined according to the actual design requirements. Each locking member 3 is arranged circumferentially around the sliding cylinder 2 with the central axis of the sliding cylinder 2 as the reference, forming a circumferentially symmetrically distributed multi-point limiting and locking structure. Correspondingly, the sliding cylinder 2 has receiving grooves 201 with the same number and one-to-one positions as the locking members 3. Each receiving groove 201 is arranged radially through the sliding cylinder 2 and is also evenly distributed circumferentially around the sliding cylinder 2. Each locking member 3 is independently and movably assembled in the corresponding receiving groove 201 and can move freely in and out radially along the sliding cylinder 2.

[0050] In this embodiment, as Figure 8 As shown, when the sliding cylinder 2 is in the first position, the multiple locking parts 3 that are evenly distributed in the circumference are simultaneously subjected to radial compression by the tapered hole section 104 on the mounting hole 103, and move synchronously towards the inside of the sliding cylinder 2 until they form a circumferential multi-point snap-fit ​​with the limiting groove 3002 on the plug-in part 3001, thereby achieving stable locking of the wiper blade 20 and the wiper arm 30.

[0051] like Figure 9 As shown, when the sliding cylinder 2 slides axially to the second position under the magnetic attraction of the external magnet 5, each locking component 3 simultaneously releases the radial constraint of the tapered hole section 104, moves synchronously to the outside of the sliding cylinder 2, and simultaneously disengages from the limiting groove 3002, thus achieving multi-point synchronous unlocking.

[0052] This design, employing at least two locking components 3 distributed circumferentially, upgrades the locking mechanism from single-point locking to multi-point synchronous engagement. With more engagement points and a larger force-bearing area, it completely avoids the problems of easy loosening and failure associated with single-point locking, significantly improving the connection reliability of the wiper blade 20 and preventing accidental detachment during vehicle operation. The evenly spaced locking components 3 along the circumference ensure a uniform distribution of radial compressive force and engagement force, preventing unilateral force from causing the sliding cylinder 2 to tilt or jam. This guarantees that the sliding cylinder 2 always slides coaxially along the axial direction, resulting in smoother movement. The multi-point locking system provides structural redundancy; even if a single locking component 3 experiences slight wear or jamming, the remaining locking components 3 can still maintain effective locking, significantly reducing the risk of overall mechanism failure and improving reliability.

[0053] Optionally, in some embodiments of this application, such as Figure 3 and Figure 4 As shown, the connector body 1 adopts a split assembly design, specifically including a connector support 101 and a connector cover 102, which work together to connect the wiper blade 20 and the wiper arm 30. Specifically, the connector support 101 is used to connect with the wiper blade 20. Optionally, the connector support 101 can be integrally molded from high-strength engineering plastic, serving as the basic load-bearing component of the connector. The bottom of the connector support 101 is provided with a connecting part (such as a snap-fit ​​groove, threaded fixing hole, or elastic snap-fit ​​assembly) adapted to the mounting position on the wiper blade 20. Through snap-fit ​​engagement, bolt tightening, or interference fit, the connector support 101 and the wiper blade 20 form a detachable or fixed connection, with no relative displacement after connection, ensuring the connection stability between the wiper blade 20 and the connector body 1. Figure 13 As shown, the connector support 101 is provided with a mounting hole 103. The mounting hole 103 can be a through-type stepped hole structure, and its inner wall is machined with a tapered hole section 104 (i.e. the mating area of ​​the locking member 3). The inner diameter of the mounting hole 103 is precisely matched with the outer diameter of the sliding cylinder 2, providing an axial sliding guide surface for the sliding cylinder 2.

[0054] like Figure 4 As shown, the connector cover 102 is fastened onto the connector support 101. Optionally, the connector cover 102 is made of a high-strength material compatible with the material of the connector support 101, and can be fastened to the top of the connector support 101 via a snap-fit ​​connection or a detachable elastic fastening structure (such as circumferentially evenly distributed elastic claws and adapter slots). Additionally, as... Figure 8 As shown, the connector cover 102 has a positioning structure (such as a limiting step, positioning boss, etc.) for the elastic element 4 on the side facing the elastic element 4, which is used to fix one end of the elastic element 4 and ensure the stable installation of the elastic element 4. Figure 4As shown, the connector cover 102 is provided with a clearance opening 1022 for the insertion piece 3001 to pass through. The inner diameter of the clearance opening 1022 is precisely matched with the outer peripheral wall size of the insertion piece 3001. In addition, a small fitting gap can be reserved between the wall of the clearance opening 1022 and the outer wall of the insertion piece 3001 to avoid direct contact and friction between the two, ensuring smooth and interference-free insertion and removal of the insertion piece 3001. At the same time, the connector cover 102 is provided with a limiting groove 1021 that mates with the limiting flange 3003 on the wiper arm 30.

[0055] This configuration ensures a tight fit between the connector support 101 and the connector cover 102, forming a stable and fixed foundation. This improves the overall structural rigidity, ensures a reliable connection between the wiper blade 20 and the wiper arm 30, and can withstand high-frequency vibrations and impacts during vehicle operation, preventing component loosening or locking failure. The modular design and snap-fit ​​assembly facilitate the installation of internal components such as the sliding cylinder 2 and the locking element 3, simplifying the assembly process, improving installation efficiency, and providing strong versatility for flexible adjustments to different wiper models.

[0056] According to embodiments of this application, in a second aspect, a windshield wiper is also provided, including the wiper blade connector 10 as described in the various embodiments above. Specifically, as Figure 1 As shown, the windshield wiper includes a wiper blade connector 10, a wiper blade 20, and a wiper arm 30. The wiper arm 30 is connected to the wiper blade 20 via the wiper blade connector 10, thereby enabling the wiper arm 30 to drive the wiper blade 20 in a reciprocating oscillating motion. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the wiper blade connector 10 described above, and therefore will not be repeated here.

[0057] According to embodiments of this application, in a third aspect, a vehicle is also provided, including a windshield wiper as described in the various embodiments above. Optionally, the vehicle is a vehicle, a low-altitude aircraft, etc. The derivation process of this beneficial effect is largely similar to the derivation process of the beneficial effect of the windshield wiper described above, and therefore will not be repeated here.
