Description

Technical Field

[0001] This invention relates to the field of window lock technology, and more particularly to a window lock assembly and a vehicle. Background Technology

[0002] Sliding windows in vehicles are a type of window that opens and closes by sliding along a track. They are characterized by saving space, easy opening, good ventilation, and high safety performance, and are widely used in vans, commercial vehicles, freight vehicles, and some passenger vehicles.

[0003] Window locks are subjected to high-frequency opening and closing and continuous vibration every day, which poses a huge challenge to the wear and fatigue life of the components. The reliability and durability of sliding window locks need to be improved. The mechanical components for automatic locking of sliding windows in vehicles in the current technology rely on motor drive, which is complex and costly, and is not suitable for scenarios with high requirements for lightweight and weather resistance (such as commercial vehicles, engineering vehicles, etc.).

[0012] According to an embodiment of the present invention, the window lock assembly further includes a connecting seat, which is connected to the vehicle window, and the connecting seat is elastically connected to the lock hook via an elastic member, the elastic member providing a locking force to the lock hook and the latch.

[0013] According to an embodiment of the present invention, in the window lock assembly, the lock hook is rotatably connected to the connecting seat via a connecting shaft.

[0022] Unless otherwise specified, the front-back direction in this application refers to the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction refers to the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction refers to the vertical direction of the vehicle, i.e., the Z direction.

[0023] The following is for reference. Figures 1-5 The window lock assembly 100 according to an embodiment of the present invention describes that after the lock hook structure and the latch 1011 are locked, the pneumatic component 211 in the safety lock assembly 2 can extend to further lock with the lock hook structure, thereby ensuring the reliability of the lock after the window has undergone high frequency of opening and closing and continuous vibration. Furthermore, the pneumatic locking structure 21 is used for upper safety locking, which is simple in structure and low in cost.

[0024] like Figure 1-5 As shown, the window lock assembly 100 of this embodiment includes: a window lock component 1 and a safety lock component 2. The window lock component 1 includes a latch 1011 and a hook structure. One of the latch 1011 and the hook structure is installed on the vehicle body and the other is installed on the window. The hook structure includes a movable hook 11, which is adapted to lock with the latch 1011. The safety lock component 2 includes a pneumatic locking structure 21, which includes a pneumatic component 211 and a pneumatic cylinder 212. The pneumatic component 211 is movably installed on the pneumatic cylinder 212. The pneumatic cylinder 212 is selectively connected to an air source. The pneumatic cylinder 212 is adapted to drive the pneumatic component 211 to lock the hook 11 after it has locked with the latch 1011 after inflation. The pneumatic cylinder 212 is also adapted to separate the pneumatic component 211 from the hook 11 after deflation.

[0025] In practice, some vehicles use sliding windows. Sliding windows save space and are convenient to open and close. The window lock assembly 1 of the sliding window includes a latch 1011 and a hook structure. The latch 1011 can be located on the vehicle body, and the hook structure can be connected to the window. The hook structure can not only act as a handle, allowing the user to pull the hook structure, thereby moving the sliding window to a position close to the latch 1011, but also includes a movable hook 11. That is, the user can pull the hook structure to move the window. After the window is pulled to the position, the hook 11 can move to lock with the latch 1011. The hook structure can be a curved hook structure. The latch 1011 includes at least a locking port 1013, so that the curved hook structure and the locking port 1013 lock together, thereby completing the initial locking of the window.

[0026] The safety lock assembly 2 includes a pneumatic component 211 and a pneumatic cylinder 212. The pneumatic component 211 can be a structure similar to a piston rod, and the pneumatic cylinder 212 is a cylinder. Inflating the cylinder can cause the pneumatic component 211 to extend or retract. The pneumatic component 211 can be directly opposite the lock hook structure. When the pneumatic component 211 extends, it limits the lock hook structure, thereby further locking. The initial locking is the locking between the lock hook 11 and the latch 1011, and the further secure locking is the locking between the pneumatic component 211 and the lock hook 11. Thus, the reliability of the locking between the sliding window and the vehicle body can be achieved.

[0027] Furthermore, the pneumatic component 211 can be connected to the vehicle's air source, so that after the pneumatic cylinder 212 is inflated, it drives the pneumatic component 211 to move to the position of the locking hook 11 and engage the safety lock. Therefore, the vehicle's air source can be used to lock the window. The structure is simple and reliable, and it can avoid the wear and failure of torsion springs and memory metal wires when using other structures. The development cost is relatively low, and it is convenient for inspection and maintenance. Moreover, the pneumatic locking method is safer and more comfortable than manual unlocking. When the locking hook 11 is worn and the locking fails, the safety lock assembly 2 can still keep the window lock assembly 1 in a locked state.

[0028] In some embodiments, the latch 1011 is installed on the window frame 101, the latch structure is installed on the movable glass 102 of the window, and the pneumatic locking structure 21 is installed on the fixed glass 103 of the window. The fixed glass 103 and the movable glass 102 are located on both sides of the window frame 101, and the movable glass 102 is adapted to move to the window frame 101, so that the latch structure locks in place with the latch 1011.

[0029] Reference Figure 1 As shown, the external structure of the latch 1011 is a plate structure. The plate structure can be connected to the window frame 101 through the first connector 1012. If the first connector 1012 is a bolt, and there are at least two bolts, the latch 1011 can be detachably connected to the window frame 101, which makes it easy to replace when the latch 1011 needs to be replaced. The latch 1011 is provided with a locking port 1013, and the locking hook 11 can be inserted into the locking port 1013 to achieve locking between the locking hook 11 and the latch 1011. The locking hook structure is installed on the movable glass 102 of the vehicle window and the pneumatic locking structure 21 is installed on the fixed glass 103 of the vehicle window. Therefore, when the user operates, he can pull the locking hook structure and move the movable glass 102 to a position close to the window frame 101 and the fixed glass 103. Since the locking hook 11 can be movably connected to the movable glass 102, after being pulled to the position, the locking hook 11 can move to extend into the locking port 1013 to achieve locking between the movable glass 102 and the window frame 101.

[0030] By placing the pneumatic locking structure 21 on one side of the window frame 101 and directly opposite the locking hook structure, the limiting cooperation between the pneumatic locking component and the locking hook structure can be facilitated, thereby ensuring the reliability of locking after the movable glass 102 is pulled and closed.

[0031] In some embodiments, the safety lock assembly 2 further includes a connecting bracket 24, a pneumatic cylinder 212 connected to the connecting bracket 24, and the pneumatic cylinder 212 is provided with an air hole. A throttle valve 22 is connected to the air hole of the pneumatic cylinder 212. The throttle valve 22 is adapted to connect to an air source so that the air source is filled into the pneumatic cylinder 212 through the throttle valve 22.

[0032] Reference Figure 4 As shown, the connecting bracket 24 is L-shaped and includes a connecting base plate 241 and a connecting side plate 242. The connecting base plate 241 is connected to the fixed glass 103, and the connecting side plate 242 is connected to the connecting base plate 241. The connecting base plate 241 is provided with multiple connecting posts 2411, and each connecting post 2411 is provided with a second connecting hole 2410. The connecting base plate 241 is bonded to the fixed glass 103, and bolts can be passed through the second connecting holes 2410 of the connecting posts 2411 to connect the connecting bracket 24 to the fixed glass 103. The connecting side plate 242 is provided with a plug hole 243, which allows the pneumatic cylinder 212 to extend into the plug hole 243 and connect with the connecting side plate 242. After insertion, it can be connected through other connecting parts. The pneumatic component 211, which is the piston rod, can extend and retract relative to the pneumatic cylinder 212 to achieve a limiting engagement between the pneumatic component 211 and the locking hook 11. Therefore, the connecting bracket 24 can be set to easily fix the pneumatic locking structure 21 connected to the glass 103, so that the position of the pneumatic locking structure 21 corresponds to the position of the locking hook 11, which facilitates the limiting locking engagement between the pneumatic component 211 and the locking hook 11 when it extends.

[0033] In addition, the throttle valve 22 is connected to the pneumatic cylinder 212, and the air outlet of the throttle valve 22 and the air outlet of the pneumatic cylinder 212 are directly opposite each other. When the throttle valve 22 is connected to the air source in the vehicle, the throttle valve 22 can adjust the gas flow rate into the pneumatic cylinder 212 and precisely control the movement speed and position of the pneumatic component 211 in the pneumatic cylinder 212, thereby achieving effective locking between the pneumatic component 211 and the locking hook 11.

[0034] In some embodiments, the connecting bracket 24 is also connected to a protective cover 25, which covers the pneumatic component 211, the pneumatic cylinder 212 and the throttle valve 22.

[0035] Reference Figure 4As shown, the connecting base plate 241 of the connecting bracket 24 is provided with multiple connecting posts 2411. Each connecting post 2411 is provided with a second connecting hole 2410 that passes through the axial direction of the connecting post 2411. The protective cover 25 is provided with multiple third connecting holes 251, and the multiple third connecting holes 251 and the multiple second connecting holes 2410 correspond one-to-one. The second connecting piece 23 passes through the third connecting holes 251 and the second connecting holes 2410, thereby realizing the connection between the protective cover 25 and the connecting bracket 24. If the connecting base plate 241 of the connecting bracket 24 is constructed into a square structure, the four corners of the square structure are provided with connecting posts 2411, and each connecting post 2411 is provided with a second connecting hole 2410. After the protective cover 25 and the connecting bracket 24 are connected by bolts, the force is more even, the structural strength of the connection is improved, and the reliability of the connection is higher.

[0036] Furthermore, the protective cover 25 is detachably connected to the connecting bracket 24, and the protective cover 25 protects the pneumatic cylinder 212 and the pneumatic component 211, preventing dust from entering the pneumatic cylinder 212 and the pneumatic component 211, and can prevent the movable glass 102 from being opened after the pneumatic cylinder 212 and the pneumatic component 211 are damaged, thus serving as an anti-theft function.

[0037] In some embodiments, the locking hook 11 includes a connected main body 111 and a locking part 112. The main body 111 is movably connected to the vehicle window. The locking part 112 includes a connected latch 1122 and an upper safety part 1121. The upper safety part 1121 is provided with a first limiting hole 1120. After the latch 1122 is locked with the latch 1011, the pneumatic locking structure 21 is adapted to insert the pneumatic component 211 into the first limiting hole 1120 when inflated. Alternatively, the upper safety part 1121 includes a pressing surface 1123. The pneumatic component 211 and the pressing surface 1123 are distributed along the inside and outside direction of the vehicle. After the latch 1122 is locked with the latch 1011, the pneumatic component 211 is adapted to press against the pressing surface 1123 to lock when it approaches the locking hook 11.

[0038] Reference Figure 2As shown, the main body 111 and the locking part 112 of the locking hook 11 are connected as one piece, and the main body 111 is movably connected to the movable glass 102, so that the locking hook 11 can be movably connected to the movable glass 102. The locking part 112 can be a hook structure formed by bending along the end of the main body 111. The locking part 112 can extend in different directions along the main body 111, and extends to one side to form a locking tongue 1122. The locking tongue 1122 can lock with the latch 1011. The upper safety part 1121 extends toward the side opposite to the locking tongue part 1122, and a first limiting hole 1120 can be provided at the position of the upper safety part 1121. The central axis of the first limiting hole 1120 is collinear with the central axis of the retractable pneumatic component 211. Therefore, after the air source in the vehicle is started and the air source enters the pneumatic cylinder 212, the pneumatic component 211 can extend out of the pneumatic cylinder 212 and lock with the first limiting hole 1120.

[0039] Of course, the locking engagement between the locking hook 11 and the pneumatic component 211 can also be configured in other ways, such as a pressure limiting method. For example, the end of the pneumatic component 211 may be provided with a pressure head 2111, which may be made of rubber material, and the upper safety part 1121 may be... Figure 3 The structure, that is, the bolt portion 1122 is still bent towards the locking port 1013, realizes the locking engagement between the bolt and the locking port 1013, and the pressing surface 1123 of the upper safety portion 1121 can be Figure 3 The upper surface of the locking hook 11 is covered by the pneumatic member 211, and the pressing head 2111 of the pneumatic member 211 is higher than the pressing surface 1123 of the upper safety part 1121. Thus, when the pneumatic member 211 is extended, the pressing head 2111 of the pneumatic member 211 presses against the pressing surface 1123 of the locking hook 11 to achieve limit locking.

[0040] Furthermore, the pressure head 2111 is made of rubber. After the pressure head 2111 of the pneumatic component 211 presses against the pressure surface 1123 of the upper safety part 1121, the rubber pressure head 2111 is pressed down, and friction is generated between the rubber material and the pressure surface 1123. The friction and the deformation of the rubber pressure head 2111 at this time can be used to reliably limit the position between the pneumatic component 211 and the upper safety part 1121. In other words, the limiting position between the pneumatic component 211 and the locking hook 11 can be achieved not only by insertion but also by pressure limiting. Of course, other limiting methods can also be used, as long as the limiting and locking between the pneumatic component 211 and the locking hook 11 can be achieved.

[0041] In some embodiments, the window lock assembly 100 further includes a reinforcing member 12, which has a second limiting hole 121. The reinforcing member 12 is connected to the upper safety part 1121, and the second limiting hole 121 and the first limiting hole 1120 are directly opposite each other.

[0042] Reference Figure 2 As shown, the reinforcing member 12 can be constructed as an L-shaped structure, with one side of the L-shaped structure connected to the locking hook 11 and the other side connected to the upper safety part 1121. The reinforcing member 12 is provided with a second limiting hole 121, and the upper safety part 1121 of the locking hook 11 is provided with a first limiting hole 1120. The first limiting hole 1120 and the second limiting hole 121 are directly opposite each other, and the central axis of the pneumatic member 211 is collinear with the central axes of the first limiting hole 1120 and the second limiting hole 121. The reinforcing member 12 can be integrally formed with the locking hook 11 by welding or integral molding, thereby improving the structural strength of the upper safety part 1121 of the locking hook 11. The pneumatic member 211 extends into the first limiting hole 1120 and the second limiting hole 121 to lock the pneumatic member 211 with the locking hook 11, thereby improving the strength and reliability of the locking point between the pneumatic member 211 and the locking hook 11, and increasing the service life of the locking hook 11.

[0043] In some embodiments, the lock hook structure further includes a connecting seat 17, which is connected to the vehicle window and is elastically connected to the lock hook 11 via an elastic member 13. The elastic member 13 provides a locking force to the lock hook 11 and the latch 1011.

[0044] Reference Figure 2 As shown, the connecting seat 17 can be glued to the car window. When the connecting seat 17 is connected to the movable glass 102, the connecting seat 17 is glued to the movable glass 102. The connecting seat 17 is provided with an elastic connecting part 172. The elastic element 13 can be a spring. One end of the spring is connected to the elastic connecting part 172 and the other end is connected to the locking hook 11. Thus, the locking hook 11 and the connecting seat 17 can be elastically connected by the spring. When the locking hook 11 pulls the movable glass 102 to contact the car window frame 101, the spring can give the locking hook 11 a force toward the latch 1011, thereby locking the locking hook 11 with the locking stop 1013.

[0045] The spring can be set to at least two. If there are two springs, the two springs are distributed at intervals along the length of the connecting seat 17. That is, the connecting seat 17 is provided with two elastic element connecting parts 172. One end of each spring is connected to the corresponding elastic element connecting part 172, and the other end is connected to the locking hook 11. Thus, when the elastic force of the spring is applied to the locking hook 11 towards the locking buckle 1011, the force is balanced.

[0046] Of course, in practice, multiple springs can be set. Multiple springs can be distributed at equal intervals along the length of the connecting seat 17, and the direction of the elastic force of each spring is the direction that makes the locking hook 11 face the locking port 1013 of the latch 1011, thereby increasing the elastic force of the locking hook 11 towards the latch 1011, and thus increasing the locking force between the locking hook 11 and the locking port 1013.

[0047] In some embodiments, the locking hook 11 is rotatably connected to the connecting seat 17 via the connecting shaft 14. At least a portion of the connecting shaft 14 is configured as an elastic structure 141. The connecting seat 17 includes two connecting surfaces 171, each of which is provided with a first connecting hole 1711. The connecting shaft 14 is pressed against the two connecting surfaces 171 under the action of the elastic structure 141. When the connecting shaft 14 is aligned with the first connecting hole 1711, the elastic structure 141 resets so that the connecting shaft 14 passes into the first connecting hole 1711.

[0048] Continue to refer to Figure 2 As shown, the elastic structure 141 can also be a spring, meaning the length of the connecting shaft 14 can be changed through the elastic structure 141. The locking hook 11 is provided with an installation channel 1111. The connecting shaft 14 extends into the installation channel 1111 and is installed in the locking hook 11. At least a part of the connecting shaft 14 is the elastic structure 141. The two ends of the connecting seat 17 are provided with connecting surfaces 171. When the connecting shaft 14 is located in the connecting seat 17 and the two ends of the connecting shaft 14 are pressed against the two corresponding connecting surfaces 171, the elastic structure 141 is squeezed. When the two ends of the connecting shaft 14 correspond to the first connecting holes 1711 of the two connecting surfaces 171 respectively, the elastic structure 141 is reset, allowing the two ends of the connecting shaft 14 to be inserted into the corresponding first connecting holes 1711, realizing the movable connection between the connecting shaft 14 and the connecting seat 17. This facilitates the connection between the connecting shaft 14 and the connecting seat 17, and does not require many parts, resulting in a simple structure.

[0049] Therefore, by setting the connecting shaft 14, a rotatable connection is achieved between the locking hook 11 and the connecting seat 17. When the locking hook 11 is rotated and pulled, the movable glass 102 moves to a position close to the window frame 101. After being pulled to the position, the locking hook 11 is released, and the locking hook 11 can rotate around the axis of the connecting shaft 14 under the action of the elastic element 13 until it locks with the latch 1011. It should be noted that the pressing head 2111 presses down on the locking hook 11, restricting the rotation path of the locking hook 11 around the connecting seat 17 (i.e., the locking hook 11 cannot disengage from the latch 1011). The opening path is restricted and jammed, and the safety lock assembly 2 cannot be opened after locking, ensuring that the movable glass 102 cannot be opened when closed.

[0050] In some embodiments, the locking hook structure further includes a base plate assembly, which includes a base plate 15 and at least one gasket 16. The base plate 15 is connected to the window, the gasket 16 is detachably connected to the outside of the base plate 15, and the connecting seat 17 is detachably connected to the outside of the gasket 16.

[0051] The base plate 15 can be bonded to the movable glass 102, and the base plate 15 is provided with at least two mounting posts 151. The gasket 16 can be set as one or more, and each gasket 16 is provided with a gasket hole 161 corresponding to the position of the mounting post 151, so that the mounting post 151 can be inserted into the gasket hole 161 of the gasket 16 to achieve the positioning connection between the gasket 16 and the base plate 15. The height of the connecting seat 17 can be adjusted by adjusting the number of gaskets 16, where the height refers to the distance between the connecting seat 17 and the movable glass 102, so as to adapt to window frames 101 of different heights, so that the locking hook 11 can be locked and connected with the locking buckle 1011 of different window frames 101, and the safety lock assembly 2 locks the locking hook 11.

[0052] In addition, the mounting post 151 is provided with mounting holes, and the connecting seat 17 can be connected to the mounting holes of the mounting post 151 by using internal hexagonal self-tapping screws, thereby realizing the connection between the base plate 15, the gasket 16 and the connecting seat 17. The position of the connecting seat 17 corresponding to the mounting hole and the position of the aforementioned elastic element connecting part 172 can be in the same position. For example, one end of the spring can be sleeved outside the internal hexagonal self-tapping screw, which does not affect the elastic connection between the locking hook 11 and the connecting seat 17 through the elastic element 13.

[0053] When the movable glass 102 is in the closed state and the locking hook 11 is locked with the latch 1011, when the throttle valve 22 is inlet, the pneumatic cylinder 212 is pushed out by the air pressure due to the intake of air, the stroke of the pneumatic component 211 increases, and the pneumatic component 211 is pushed into the first limiting hole 1120 on the locking hook 11 and the second limiting hole 121 of the reinforcing member 12. Because the locking hook 11 is pushed in by the pneumatic component 211, the rotation path of the locking hook 11 around the connecting seat 17 is restricted (that is, the locking hook 11 cannot disengage from the latch 1011). The opening path is restricted and locked, the locking hook 11 and the latch 1011 are locked and cannot be opened, ensuring that the movable glass 102 cannot be opened when it is in the closed state.

[0054] When the movable glass 102 is closed, the locking hook 11 and the latch 1011 are locked, and the throttle valve 22 is depressurized, the pneumatic component 211 of the pneumatic cylinder 212 retracts under the pressure difference due to the depressurization. The stroke of the pneumatic component 211 decreases, and the pneumatic component 211 inside the first limiting hole 1120 of the locking hook 11 and the second limiting hole 121 of the reinforcing member 12 no longer restricts the opening path of the locking hook 11. The locking hook 11 and the latch 1011 can be unlocked, and the window can be opened and closed freely. In addition, when the pneumatic locking structure 21 is not connected to the vehicle's air circuit (or the air circuit is cut off), the pneumatic component 211 is in the retracted state, does not restrict the movement of the locking hook 11, and the movable glass 102 can be opened / closed freely without affecting manual operation.

[0055] The window lock assembly 100 combines mechanical structure with pneumatic control to achieve automatic locking / unlocking of the movable glass 102. Through vehicle-wide pneumatic circuit linkage, automatic switching between locking and unlocking is achieved, eliminating the need for manual operation and enhancing convenience. The pneumatic drive provides rapid response, and the pneumatic component 211 directly and mechanically limits the locking hook 11, ensuring a stable lock and preventing accidental opening of the movable glass 102, resulting in high reliability. The window lock assembly 100 supports drilling or adhesive installation, adapting to different glass thicknesses and window frames 101, offering flexible installation. The protective cover 25 covers the core pneumatic locking structure 21, preventing malicious damage and providing good anti-theft performance. The safety lock component 2 does not affect the manual operation of the movable glass 102 when not in use, adapting to traditional usage habits, exhibiting strong compatibility, simple structure, low cost, and high reliability, making it suitable for commercial vehicles, engineering vehicles, and other scenarios with high safety and automation requirements. In other words, the pneumatic component 211 of the pneumatic locking structure 21 in this embodiment of the invention inserts and withdraws from the locking hook 11 and the reinforcing component 12 to form a mechanical "pin" or "latch" effect to complete locking and unlocking. Therefore, the structure is simple, easy to maintain and repair, and has low research and development costs.

[0056] This invention also discloses a vehicle including the aforementioned window lock assembly 100. It uses only two standard components, a pneumatic component 211 and a throttle valve 22, to control the locking and unlocking states of the sliding windows. The structure is simple and easy to replace and maintain. Simultaneously, the bus can connect the safety lock assemblies 2 of all sliding windows via a pneumatic circuit. A hand-operated valve at the driver's location allows simultaneous control of the locking and unlocking states of all sliding windows. No electricity or network is required, making operation simple and exhibiting good stability and functional reliability.
