Description
Technical Field
[0001] This utility model relates to the field of vehicle manufacturing, and in particular to a conveniently installed interlocking device for a charging port door and a sliding door, and an automobile. Background Technology
[0002] In some car models with sliding doors, including both gasoline and new energy vehicles, the refueling door is located on the rear side panel near the D-pillar. The opening of the sliding door needs to be controlled to ensure that when it is moved to its maximum position towards the rear of the vehicle, it does not touch the refueling port. This prevents the sliding door from accidentally opening during refueling, which could lead to a collision with the refueling port and refueling nozzle, causing safety accidents such as fires, energy leaks, or electric shocks. However, this design can result in a small opening, making it difficult for passengers to get in and out. To ensure that the overall opening meets both passenger comfort and the energy delivery path requirements, the refueling port overlaps with the sliding door. However, when the refueling port is open for refueling, passengers may open the sliding door to exit the vehicle, at which point the sliding door could collide with the refueling nozzle, leading to a safety accident. To address the aforementioned technical issues, existing technologies employ an interlocking device to interlock the sliding door and the small energy supply port door, ensuring that the sliding door remains locked when the small energy supply port door is open.
[0003] However, the interlocking devices used in existing technologies have a high complexity in cable installation during automobile assembly. For example, the authorized announcement number "CN204663217U", entitled "An Interlocking Device for a Sliding Door and a Fuel Filler Neck", specifically discloses "a fuel filler neck control mechanism located at the fuel filler neck, a locking mechanism located on the side of the vehicle body for restricting the movement of the sliding door, and a cable connecting the fuel filler neck control mechanism and the locking mechanism. The fuel filler neck control mechanism includes a fuel filler neck bracket, a fuel filler neck, and a hinge. The locking mechanism includes a lock bracket, a lock tongue, and a return spring. The lock tongue is hinged to the lock bracket. One end of the cable is fixed to the hinge, and the other end of the transmission mechanism is fixed..." The lock tongue is fixed at one end, and the return spring connects the other end of the lock tongue and the lock bracket. The cable is connected to the hinge with a cable fixing head. The hinge has a cable mounting hole and a cable fixing groove communicating with the cable mounting hole. The cable fixing groove is a strip-shaped structure, and the cable fixing head is installed into the cable fixing groove through the cable mounting hole. The filler neck bracket has a fixing seat mounting hole. The cable fixing seat includes a cable sleeve on one side of the fixing seat mounting hole and a retainer on the other side of the fixing seat mounting hole. In this invention, the cable needs to be precisely embedded into the cable fixing groove of the hinge through the cable fixing head, and the assembly of the cable fixing seat involves the coordinated fixing of the cable sleeve (spiral rubber sleeve) and the retainer spring. If the cable length is improperly adjusted or the sleeve elasticity is not calibrated, the cable may become loose or excessively tight, affecting the lifting and resetting of the lock tongue. Furthermore, while the dual-spring design of the card slot simplifies the fixing process, it is prone to failure during mass assembly due to spring deformation or positioning deviation. The cable sleeve needs to simultaneously satisfy the functions of waterproof sealing and elastic expansion, but during assembly, it is necessary to ensure that the sleeve compression is moderate. If the sleeve is over-compressed, it may lose its elasticity and affect the cable transmission; if it is under-compressed, it will not be effective in waterproofing. This balance is difficult to achieve through standardized procedures and requires judgment based on human experience.
[0004] In summary, existing interlocking devices are highly dependent on component precision, tolerance matching, and manual operation during assembly, resulting in low assembly efficiency, increased costs, and susceptibility to functional problems caused by minor deviations. Utility Model Content
[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a conveniently installed interlocking device for the charging port door and the sliding door, as well as a car, which reduces the reliance on manual operation, improves assembly efficiency, reduces costs, and reduces the occurrence of functional problems caused by minor deviations in assembly.

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.
[0035] It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings of this specification are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation of this utility model. Therefore, they have no substantial technical significance.

Furthermore, the terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of implementation of this utility model.
[0036] like Figures 1 to 14 As shown, this utility model provides an embodiment of a conveniently installed charging port and sliding door interlocking device, including a housing 100, a cover plate assembly 200, a sliding door locking device 300, a pull cable 400, and a drive device 500. The cover plate assembly 200 is hinged to the housing 100. The housing 100 is provided with a mounting seat for mounting the drive device 500. One end of the hinge shaft between the housing 100 and the cover plate assembly 200 is provided with a swing part 600 extending to the outside of the housing 100. The swing part 600 is connected to the drive device 500. Both ends of the pull cable 400 are provided with fixing heads. One fixing head of the pull cable 400 is connected to the swing part 600. This connection method includes, but is not limited to, snap-fit, and can also adopt a detachable connection method, such as threaded connection, pin connection, bayonet connection, etc. The other fixing head of the pull cable 400 is connected to the sliding door locking device 300. The swinging part 600 can be connected to the output end of the drive device 500 via a transmission assembly; alternatively, the swinging part 600 can be directly connected to the output end of the drive device 500, allowing the swinging part 600 to swing within a predetermined angle range. In this embodiment, the drive device 500 is preferably a rotary actuator. The housing 100 is provided with a locking rod buckle structure. The locking rod 700 is assembled to the housing 100 via a snap-fit mechanism, with one end of the locking rod having a lock head 710 and the other end inserted into the locking actuator 800. The bottom of the cover assembly 200 has a lock hole for the locking rod 700 to be inserted into. The locking actuator controls the locking rod 700 to insert into or retract from the lock hole, thereby locking or unlocking the cover assembly 200. Since the pull cable 400 is of fixed length, it is in a slack state when both the charging door and the sliding door are closed. It should be noted that during installation, only one end of the cable needs to be snapped into the swing section 600, and then the drive unit 500 is installed. The drive unit 500, the swing section 600, and the housing 100 are then connected to form an assembly, which is then snapped into the rear side panel of the vehicle. This installation method significantly reduces the difficulty of cable installation and improves assembly efficiency. Since both the swing section 600 and the drive unit 500 are located outside the housing, it avoids creating a cable mounting groove at the hinge point between the cover assembly and the housing.
[0037] In use, when the charging port door needs to be opened, the vehicle control system sends an open signal, and the locking actuator 800 drives the locking rod to move axially out of the lock hole. Then, the drive unit 500 receives the open signal and drives the swing part 600 to swing upward, causing the swing part 600 to swing to its limit position within a predetermined angle range, thereby driving the cover assembly to rotate until it is fully open. At this time, the swing part 600 tightens the cable 400, which drives the sliding door locking device 300 to lock it, forming an interlocked state. Passengers inside the vehicle cannot open the sliding door, preventing safety accidents. When the charging port door is closed, opening the sliding door will cause the sliding door locking device 300 to tighten the cable 400, which in turn will cause the swing part 600 to swing downward to its limit position, i.e., the swing part 600 is in a locked state, forming an interlocked state. At this time, even if the driver sends a signal to open the charging port door through the vehicle control system, the drive device 500 cannot drive the swing part 600 to swing, so as to ensure that there is no interference between the charging port door and the sliding door.
[0038] In one embodiment, such as Figures 1 to 8 As shown, the swing part 600 includes a transmission component 610 and a locking component 620. The transmission component 610 is fixed to one end of the hinge shaft to ensure that the drive device 500 drives the transmission component 610 to rotate, thereby driving the hinge shaft to rotate, and thus realizing the opening or closing of the cover assembly 200. The locking component 620 and the transmission component 610 can be integrated, or they can be detachably connected. During installation, the cable fixing head is simply snapped into the locking component 620. In use, when the drive device 500 drives the transmission component 610 to rotate upward, it drives the locking component 620 to pull the cable 400 upward, so that the sliding door is in a locked state. It should be noted that, in order to avoid interference between the cable 400 and the rotating transmission component 610, in a preferred embodiment, the locking component 620 and the transmission component 610 are eccentrically arranged, with the cable 400 locked at the end of the locking component 620 away from the transmission component 610.
[0039] In one embodiment, such as Figure 2 , Figure 4 and Figure 6As shown, in this embodiment, when the clearance between the drive unit and the vehicle sheet metal is insufficient, the transmission component 610 is preferably configured in a gear-like structure. The transmission component 610 meshes with the gear on the output shaft of the drive unit, and the transmission ratio of the two gears is 1:1. When it is necessary to open the cover plate 200 assembly, the gear on the output shaft of the drive unit rotates counterclockwise by a predetermined angle, and the transmission component 610 rotates clockwise by the same angle, thereby tightening the cable and preventing passengers from opening the sliding door while the vehicle is charging. After charging is completed, when it is necessary to close the cover plate assembly 200, the output gear on the drive unit 500 rotates clockwise, causing the transmission component 610 to rotate counterclockwise by the same angle, so that the cable connecting the sliding door and the transmission component 610 is in a slack state. When it is necessary to open the sliding door, the sliding door locking device 300 unlocks, thereby tightening the cable. Under the tension of the cable, the transmission component 610 rotates counterclockwise to its limit position, and at the same time, it causes the output shaft of the drive unit to rotate clockwise by the same angle. At this time, both the drive unit 500 and the transmission component 610 are in a locked state. If the driver mistakenly sends a signal to the vehicle control system to open the charging port door, the output shaft of the drive unit cannot drive the transmission component 610 to rotate, ensuring that the cover assembly 200 is in a non-opening state and avoiding mechanical damage to the cover assembly 200 during the sliding door closing process. In addition, when the clearance between the drive unit and the vehicle sheet metal is insufficient, the transmission component 610 can be directly mounted on the output shaft of the drive unit, which can also achieve the technical effect of this embodiment.
[0040] In one embodiment, such as Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the snap-fit component 620 includes a first base 621 for mounting the cable and a snap-fit protrusion 622 for snapping the cable. The first base 621 is fixed to the transmission component 610, and the snap-fit protrusion 622 is fixed to the first base 621. A gap 630 is provided between the snap-fit protrusion 622 and the first base 621 to allow the cable body to move, preventing the cable 400 from being subjected to radial shear force by the first base 621 when tensioned, thereby improving the service life of the cable 400. Preferably, the gap 630 is provided around the outer side wall of the snap-fit protrusion 622 and the first base 621. The snap-fit protrusion 622 includes a groove 6221 for snapping the cable 400. The groove 6221 communicates with the gap 630, and the opening of the groove 6221 faces the side where the transmission component 610 is located. The shape of the groove 6221 matches the shape of the cable fixing head to prevent the cable fixing head from detaching during operation. During installation, the cable fixing head engages with the groove 6221 at the point where the opening of the groove 6221 connects to the gap 630. The cable body is located within the gap 630, and the bottom of the groove 6221 connects to the gap 630. When the engaging protrusion 622 and the first base 621 rotate upwards to tighten the cable, the cable fixing head rotates accordingly, thereby causing the cable body to move along the gap, thus opening the cover assembly. Figure 4 The posture shown. Similarly, when the sliding door locking device 300 tightens the cable, the cable fixing head drives the locking protrusion 622 and the first base 621 to rotate downwards, locking the cover plate assembly 200, as shown. Figure 6 The posture shown. In addition, in order to ensure that the cable fixing head can work stably, a mounting hole for placing the cable fixing head can be opened on the first base 621 in the area corresponding to the groove 6221 to prevent the cable fixing head from falling out of the groove.
[0041] In one embodiment, such as Figure 11 and Figure 12 As shown, the cover plate assembly 200 includes an inner plate 210 and an outer plate 220. The inner plate 210 has multiple first guide blocks 211 arranged on it to restrict the degrees of freedom in the Y and Z axes. The outer plate 220 has second guide blocks 221 corresponding to the first guide blocks 211, and the first guide blocks 211 and second guide blocks 221 engage with each other. The inner plate 210 has a first elastic locking part 212, and the outer plate 220 has a second elastic locking part 222, which engages with the first elastic locking part 212. Both the first elastic locking part 212 and the second elastic locking part 222 have matching inclined surfaces. In use, the outer plate 220 slides along the X-axis of the inner plate 210. When the second elastic locking part 222 passes over the first elastic locking part 212 along the inclined surface, they engage with each other. At this time, the second guide block 221 and the first guide block 211 engage with each other to achieve the restriction of the degree of freedom in the X-axis direction.
[0042] In one embodiment, such as Figure 13 and Figure 14 The sliding door locking device 300 includes a second base 310, a latch 320 for connecting a cable, and a limiting part 330 for limiting the latch. The latch 320 is hinged to the second base 310. When the sliding door is unlocked, the latch 320 rotates to a predetermined angle and abuts against the limiting part 330 to prevent excessive rotation of the latch 320 and potential cable breakage. When the sliding door is closed, the latch 320 rotates away from the limiting part 330.
[0043] In another aspect, this utility model proposes an automobile that includes a conveniently installed charging port and a sliding door interlocking device as described in the above embodiments, in order to improve assembly efficiency and reduce production costs.
[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
