Description

Technical Field

[0001] The present invention relates to the technical field of vehicle sliding door systems, and in particular to a vehicle sliding door lock system and a vehicle. Background Art

[0002] To facilitate the entry and exit of passengers and cargo, there is a growing demand for side sliding doors on the rear doors of light buses and logistics vehicles. Their key feature is that they can be opened by simply sliding them sideways, rather than pushing them outward. This reduces the need for pushing the door outward, allowing the door to open by simply sliding it back, saving space. Side sliding doors also facilitate passenger entry and exit, as well as cargo unloading. Side sliding doors are larger than side-opening doors, and can easily produce noise during driving if the door locks are not properly secured. Furthermore, some vehicles have the fuel filler port located behind the sliding door. If a passenger slides the door during refueling, it can collide with the fuel cap and pump, creating a dangerous situation. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0030] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0031] Combine Figures 1 to 9 As shown, this embodiment provides a sliding door lock system for a vehicle, which can prevent the sliding door from hitting the energy filling port cover 20a when the vehicle is refueling with energy.

[0032] Combine Figure 5 As shown, the sliding door lock system includes a sliding door main lock 10. The sliding door main lock 10 comprises a lock body and a main lock catch. The lock body comprises a lock housing and a main lock tongue connected to the lock housing. The main lock tongue is connected to the vehicle's sliding door via the lock housing. The main lock tongue is retractable relative to the lock housing. The main lock tongue has a locked state (engaged with the main lock catch) and an unlocked state (detached from the main lock catch). The main lock catch is connected to the vehicle's side panel 30. In this embodiment, the sliding door main lock 10 is a mechanical lock. Its specific structure is not limited, as long as it can secure the sliding door and can be unlocked after being secured.

[0033] For example, the lock body is screwed to the inner panel of the sliding door and the inner panel reinforcement through three bolts, the main lock buckle is screwed to the outer panel of the side panel 30 of the vehicle through bolts, and the lock body is engaged and locked with the main lock buckle through the lock tongue to achieve a locked state.

[0034] It should be understood that when the vehicle's sliding door reaches the closed position, the main lock tongue and the main lock catch can engage to secure the vehicle's sliding door in the closed position. When the vehicle's sliding door needs to be opened, the main lock tongue and the main lock catch can separate to allow the vehicle's sliding door to move out of the closed position. When the vehicle's sliding door reaches the closed position, the main lock tongue and the main lock catch can engage automatically or by other actuation methods.

[0035] Further, combined with Figure 1 As shown, the sliding door lock system further includes a conversion mechanism 12, which is transmission-connected to the main lock tongue to drive the main lock tongue to switch between an unlocked state and a locked state. In this embodiment, the sliding door lock system further includes a first drive link 11, and the lock body further includes a main lock rocker arm transmission-connected to the main lock tongue. One end of the first drive link 11 is transmission-connected to the main lock rocker arm, and the other end of the first drive link 11 is transmission-connected to the conversion mechanism 12.

[0036] It should be understood that the conversion mechanism 12 drives the first drive link 11, which in turn drives the main lock rocker arm, and finally drives the main lock tongue to switch between the locked state and the unlocked state through the main lock rocker arm.

[0037] Further, combined with Figure 1 and Figure 2 As shown, the sliding door lock system also includes a switch assembly, which is in transmission connection with the conversion mechanism 12 to drive the conversion mechanism 12, thereby driving the main lock tongue to switch between the unlocked state and the locked state. In this embodiment, the switch assembly includes a locking portion 13a, an inner opening portion 13b, and an outer opening portion 13c, each of which has an open position and a closed position. The inner opening portion 13b and the outer opening portion 13c are both in transmission connection with the conversion mechanism 12. When the inner opening portion 13b and the outer opening portion 13c switch between the open and closed positions, they correspondingly drive the main lock tongue to switch between the unlocked state and the locked state. When the locking portion 13a is in the closed position, the inner opening portion 13b and the outer opening portion 13c remain in the closed position.

[0038] For example, combining Figure 1 and Figure 2As shown, the conversion mechanism 12 includes a main body 121, a second drive link 122, an outward opening link 123, an inward opening link 124, a locking link 125, a first conversion rocker arm 126, a second conversion rocker arm 127, and a third conversion rocker arm 128 rotatably connected to the main body 121. The outward opening link 123 is transmission-connected between the first conversion rocker arm 126 and the outward opening portion 13c; the inward opening link 124 is transmission-connected between the first conversion rocker arm 126 and the inward opening portion 13b; the second drive link 122 is transmission-connected between the first conversion rocker arm 126 and the third conversion rocker arm 128; the first drive link 11 is transmission-connected between the third conversion rocker arm 128 and the main lock rocker arm; and the locking link 125 is transmission-connected between the second conversion rocker arm 127 and the locking portion 13a. Among them, the second conversion rocker arm 127 is connected to the first conversion rocker arm 126.

[0039] It should be understood that, during the process of the inner opening portion 13b switching from the closed position to the open position, the inner opening link 124 can drive the first conversion rocker arm 126, which can drive the second drive link 122, which then drives the third conversion rocker arm 128 through the second drive link 122, and then drives the first drive link 11 through the third conversion rocker arm 128, thereby driving the main lock rocker arm, and finally the main lock rocker arm drives the main lock tongue to switch from the unlocked state to the locked state. During the process of the outer opening portion 13c switching from the closed position to the open position, the outer opening link 123 can drive the first conversion rocker arm 126, which can drive the second drive link 122, and then drives the third conversion rocker arm 128 through the second drive link 122, and then drives the first drive link 11 through the third conversion rocker arm 128, thereby driving the main lock rocker arm, and finally the main lock rocker arm drives the main lock tongue to switch from the unlocked state to the locked state.

[0040] Furthermore, during the process of switching the locking portion 13a from the open position to the closed position, the locking portion 13a drives the locking link 125, which in turn drives the second switching rocker arm 127 via the locking link 125. This, in turn, positions the first switching rocker arm 126 via the second switching rocker arm 127, preventing the inward-opening portion 13b and the outward-opening portion 13c from switching from the closed position to the open position. During the process of switching the locking portion 13a from the closed position to the open position, the locking portion 13a drives the locking link 125, which in turn changes the position of the second switching rocker arm 127 via the locking link 125, allowing the first switching rocker arm 126 to move under the action of the inward-opening link 124 and the outward-opening link 123.

[0041] Further, combined with Figure 1 、 Figure 3 and Figure 4As shown, the sliding door lock system further includes a connector 14, which is configured to connect to the vehicle's energy filler cap 20a and the vehicle's side panel 30 and is capable of synchronous movement with the energy filler cap 20a relative to the vehicle's side panel 30. In this embodiment, the connector 14 includes a female hinge 141 and a male hinge 142 that are hingedly connected to each other. The female hinge 141 is configured to connect to the vehicle's side panel 30, and the male hinge 142 is configured to connect to the vehicle's energy filler cap 20a and is capable of movement with the vehicle's energy filler cap 20a.

[0042] For example, the energy filler cap 20 a is fixedly connected to the male hinge 142 and can move synchronously with the male hinge 142 .

[0043] Furthermore, the sliding door lock system includes a first linkage assembly, which is transmission-connected between the male hinge 142 of the connecting member 14 and the main lock tongue. The first linkage assembly is configured to drive the main lock tongue from an unlocked state to a locked state when the energy filler cover 20a is opened. In this embodiment, the first linkage assembly is transmission-connected between the male hinge 142 of the connecting member 14 and the main lock rocker arm, thereby driving the main lock tongue via the main lock rocker arm.

[0044] In summary, when the vehicle's energy filler lid 20a is opened, the sliding door lock system causes the male hinge 142 of the connector 14 to move synchronously with the energy filler lid 20a relative to the vehicle's side panel 30, thereby driving the movement of the first linkage assembly. Ultimately, the first linkage assembly actuates the primary lock rocker arm, which in turn actuates the primary lock tongue from an unlocked state to a locked state, thereby engaging the primary lock tongue and the primary lock catch. At this point, the vehicle's sliding door is locked and cannot be opened directly without further action. This prevents the sliding door from striking the energy filler lid 20a during refueling.

[0045] Further, combined with Figures 1 to 9 As shown, the sliding door lock system further includes a sliding door lock catch 15a, a second linkage assembly 15b, and a sliding door lock hook 15c. The sliding door lock catch 15a is configured to connect to the vehicle's side panel 30. The second linkage assembly 15b is transmission-connected between the sliding door lock hook 15c and the connecting member 14 and is capable of moving with the connecting member 14. The sliding door lock hook 15c has a locked state (engaged with the sliding door lock catch 15a) and an unlocked state (detached from the sliding door lock catch 15a). Driven by the second linkage assembly 15b, the sliding door lock hook 15c can switch between the locked and unlocked states. In this embodiment, when the vehicle's energy filler door lid 20a is opened and the male hinge 142 moves synchronously with the energy filler door lid 20a relative to the vehicle's side panel 30, the first linkage assembly simultaneously drives the main lock tongue to switch from the unlocked state to the locked state, and the second linkage assembly 15b drives the sliding door lock hook 15c to switch from the unlocked state to the locked state.

[0046] For example, the second linkage component 15b is transmission-connected between the sliding door lock hook 15c and the male hinge 142. When the sliding door lock system opens the energy filler cover 20a of the vehicle, the male hinge 142 of the connecting member 14 can move synchronously with the energy filler cover 20a relative to the side panel 30 of the vehicle, thereby driving the second linkage component 15b to move. Finally, the sliding door lock hook 15c can be driven into a locked state through the second linkage component 15b, that is, the sliding door lock hook 15c is combined with the sliding door lock buckle 15a. At this time, even if the main lock tongue is in the unlocked state, the sliding door of the vehicle is also in a locked state. Without other operations, it cannot be directly opened.

[0047] It should be understood that when the energy filler port cover 20a is in the open state, the sliding door and the side panel 30 are connected and restricted by the combination of the sliding door lock hook 15c and the sliding door lock buckle 15a, and the combination of the main lock tongue and the main lock buckle. The two locked states simultaneously restrict the movement of the sliding door, avoiding that the force when the sliding door is pulled hard by humans only acts on the sliding door main lock 10, thereby limiting the opening of the sliding door and protecting the sliding door main lock 10.

[0048] Further, combined with Figure 4 As shown, the second linkage assembly 15b includes a pull rod 151 and an elastic return assembly 152. The pull rod 151 is connected between the sliding door lock hook 15c and the elastic return assembly 152. The elastic return assembly 152 is transmission-connected between the pull rod 151 and the male hinge 142 and is elastically deformed when the male hinge 142 rotates relative to the female hinge 141. In this embodiment, when the energy filler lid 20a switches from an open state to a closed state, the male hinge 142 rotates relative to the female hinge 141 and elastically deforms. In other words, when the energy filler lid 20a is closed, the elastic return assembly 152 is compressed. When the energy filler lid 20a is opened, the elastic return assembly 152 recovers its elastic deformation, thereby facilitating the opening of the energy filler lid 20a and the engagement of the sliding door lock hook 15c with the sliding door lock catch 15a.

[0049] It should be understood that the male hinge 142 has an open position and a closed position relative to the female hinge 141, and can switch between the open and closed positions when rotating relative to the female hinge 141. When the male hinge 142 is in the closed position, the sliding door lock hook 15c and the main lock tongue can both be in the unlocked state, and the elastic return assembly 152 is elastically deformed.

[0050] Further, combined with Figure 8 and Figure 9As shown, the elastic reset assembly 152 includes a fixed seat 1521, a rotating member 1522, a movable rod 1523 and a torsion spring 1524. The fixed seat 1521 is used to connect with the fuel filler box 20b of the vehicle. The torsion spring 1524 is connected to the fixed seat 1521. The rotating member 1522 is connected to the torsion spring 1524, the pull rod 151 and the movable rod 1523, and is located between the pull rod 151 and the movable rod 1523; the movable rod 1523 is transmission-connected to the male hinge 142, and has a first position and a second position that can be switched with respect to the male hinge 142.

[0051] It should be understood that the transmission connection between the movable rod 1523 and the male hinge 142 means that when the male hinge 142 switches from the closed position to the open position, the movable rod 1523 is affected by the elastic recovery ability of the torsion spring 1524, which can help push the male hinge 142 to rotate compared to the female hinge 141, so as to help open the energy filling port cover 20a; at the same time, when the male hinge 142 switches from the open position to the closed position, it can drive the movable rod 1523 to move, and then drive the rotating member 1522 to rotate through the movable rod 1523, so that the torsion spring 1524 is elastically compressed.

[0052] Furthermore, when movable rod 1523 is in the first position, torsion spring 1524 elastically deforms, and sliding door lock hook 15c is unlocked. When movable rod 1523 is in the second position, torsion spring 1524 elastically recovers its deformation, and sliding door lock hook 15c is locked. When male hinge 142 is in the closed position, movable rod 1523 remains in the first position. When male hinge 142 is in the open position, movable rod 1523 is in the second position and can switch from the second position to the first position.

[0053] In this embodiment, when the male hinge 142 is in the closed position, the movable rod 1523 remains in the first position, thereby making the sliding door lock hook 15c in the unlocked state; to avoid accidentally locking the sliding door; when the male hinge 142 is in the open position, the movable rod 1523 is in the second position, thereby making the sliding door lock hook 15c in the locked state, but the movable rod 1523 can also be switched from the second position to the first position under the action of external force, that is, even in the process of opening the energy filling port cover 20a, the movable rod 1523 can be manually pushed to drive the rotating part 1522 to rotate, so that the torsion spring 1524 is elastically compressed, and then the sliding door lock hook 15c is switched from the locked state to the unlocked state, so as to be used for emergency opening of the sliding door during refueling of the vehicle.

[0054] For example, if the vehicle is an electric vehicle (fuel filler cover 20a is a charging cover), and only the sliding door on the side of fuel filler cover 20a is easily accessible, if a charging failure occurs, preventing the gun from being drawn, and thus preventing the fuel filler cover 20a from being closed, the sliding door will ultimately remain locked. In this case, the movable rod 1523 can be manually pushed, thereby driving the rotating member 1522 to rotate, causing the torsion spring 1524 to elastically compress, thereby switching the sliding door lock hook 15c from the locked state to the unlocked state, allowing the sliding door to be opened in an emergency during refueling.

[0055] In this embodiment, when the male hinge 142 is in the closed position and the movable rod 1523 is in the first position, the movable rod 1523 passes through the fixed seat 1521 and the female hinge 141 and elastically abuts against the male hinge 142. Therefore, when the male hinge 142 switches from the closed position to the open position, the movable rod 1523 can be switched to the second position under the elastic restoring force of the torsion spring 1524, and the sliding door lock hook 15c can also switch from the unlocked state to the locked state under the elastic restoring force. At the same time, because the movable rod 1523 is not fixedly connected to the male hinge 142, when the male hinge 142 is in the open position, the movable rod 1523 can be pushed back to the first position by an external force, thereby elastically compressing the torsion spring 1524 and switching the sliding door lock hook 15c from the locked state to the unlocked state, thereby facilitating emergency opening of the sliding door during refueling.

[0056] For example, after the sliding door lock system is installed in a vehicle, the movable rod 1523 is sequentially inserted through the fixing base 1521, the fuel filler box 20b, and the female hinge 141. In other words, when the energy filler lid 20a is opened, the energy filler lid 20a and the male hinge 142 are tilted outward relative to the fuel filler box 20b, and the movable rod 1523 is exposed inside the fuel filler box 20b, allowing it to be manually pushed.

[0057] Further, combined with Figure 1 、 Figure 5 and Figure 7 As shown, the sliding door lock system also includes a sliding door secondary lock 16a; the sliding door secondary lock 16a is spaced apart from the sliding door main lock 10, and the sliding door secondary lock 16a includes a secondary lock tongue and a secondary lock buckle, one of the secondary lock tongue and the secondary lock buckle is connected to the sliding door of the vehicle, and the other is connected to the side wall 30 of the vehicle, and the secondary lock tongue has a locked state combined with the secondary lock buckle and an unlocked state separated from the secondary lock buckle; wherein, the switch assembly is transmission-connected to the secondary lock tongue to drive the secondary lock tongue to switch between the unlocked state and the locked state.

[0058] In this embodiment, after the sliding door lock system is installed in the vehicle, the sliding door secondary lock 16a and the sliding door main lock 10 are spaced apart along the height direction of the vehicle, which can ensure that the sliding door is in a limited and stable state during the movement of the vehicle, solving the shaking and abnormal noise problems of the sliding door during the movement of the existing vehicle models.

[0059] For example, the sliding door is installed on the vehicle body through a sliding rail, and the sliding rail can be set in the middle position in the height direction of the vehicle body. The sliding door secondary lock 16a and the sliding door main lock 10 are located on both sides of the sliding rail along the height direction of the vehicle. Then, the sliding door is limited in the upper, middle and lower parts in the height direction of the vehicle body through the sliding rail, the sliding door secondary lock 16a and the sliding door main lock 10, which can make the sliding door in a limited and stable state.

[0060] Furthermore, the sliding door lock system also includes a third linkage component 16b, and the sliding door secondary lock 16a also includes a secondary lock rocker arm that is transmission-connected to the secondary lock tongue. The third linkage component 16b is transmission-connected between the secondary lock rocker arm and the main lock rocker arm, so that when the switch component drives the main lock rocker arm to switch the main lock tongue to the locked state, the secondary lock tongue can also be driven to switch to the locked state through the main lock rocker arm, the third linkage component 16b and the secondary lock rocker arm.

[0061] Further, combined with Figure 1 and Figure 2 As shown, the sliding door lock system also includes a limiter 17 and a connecting harness 18 electrically connected to the sliding door main lock 10. The limiter 17 includes a door side limiter 171 and a body side limiter 172. The door side limiter 171 is used to connect to the sliding door of the vehicle and is electrically connected to the connecting harness 18; the body side limiter 172 is connected to the side panel 30 of the vehicle; wherein, when the door side limiter 171 is combined with the body side limiter 172, the main lock tongue is in a locked state; when the door side limiter 171 is separated from the body side limiter 172, the main lock tongue is in an unlocked state.

[0062] It should be understood that when the main lock tongue is locked and the door side stopper 171 is engaged with the vehicle body side stopper 172, all circuits in the wiring harness 18 are conductive, transmitting an electrical signal to the corresponding door closing sensor to indicate a successful door closing. However, when the main lock tongue is not locked or the door side stopper 171 is not engaged with the vehicle body side stopper 172, the circuits in the wiring harness 18 are not fully conductive, transmitting an electrical signal to the corresponding door closing sensor to indicate a failed door closing. Furthermore, the door side stopper 171, when engaged with the vehicle body side stopper 172, also serves to limit the sliding door, thereby enhancing its stability.

[0063] In this embodiment, the sliding door lock system includes multiple stoppers 17, which are spaced apart from each other. At least one of the stoppers 17 is connected to the connecting wire. For example, two stoppers 17 are provided. When the sliding door lock system is installed on the vehicle body, the two stoppers 17 are spaced apart along the height direction of the vehicle body on the side panel 30 to further enhance the stability of the sliding door when closed.

[0064] Furthermore, the limiter 17 also includes a door side connecting electrode and a body side connecting electrode, the door side connecting electrode is connected to the door side limiter 171 and is electrically connected to the connecting harness 18; the body side connecting electrode is connected to the body side limiter 172; wherein, when the door side limiter 171 and the body side limiter 172 are combined, the door side connecting electrode and the body side connecting electrode are electrically connected; when the door side limiter 171 and the body side limiter 172 are separated, the door side connecting electrode and the body side connecting electrode are insulated from each other.

[0065] It should be understood that the body side connecting electrode and the door side connecting electrode are used to transmit the door closing signal. After the body side connecting electrode is integrated into the body side limiter 172 and the door side connecting electrode is integrated into the door side limiter 171, it can have the function of limiting and transmitting the door closing signal at the same time. Function integration reduces costs, and the connecting harness 18 is also electrically connected to the sliding door main lock 10, and can have two door not closed signal reminders, the sliding door main lock 10 and the limiter 17, with high safety performance.

[0066] This embodiment further provides a vehicle, including a sliding door, a side panel 30, an energy filler cap 20a and the above-mentioned sliding door lock system, wherein the sliding door lock system is connected to the sliding door, the side panel 30 and the energy filler cap 20a.
