Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an electric sliding hatch. Background Technology

[0002] Traditional bus luggage compartment doors are mostly pneumatically driven, requiring a cylinder as the primary actuator and a gas spring as a secondary actuator to move the swing arm, thus opening and closing the luggage compartment door. The cylinder control device for this type of luggage compartment door is located inside the luggage compartment, which not only intrudes on the compartment space but also produces loud airflow noise and poor sound quality when opening and closing. Chinese Patent Application No. 202020286226.3 discloses an electric luggage compartment door. This technical solution uses a combination of electric struts and gas springs to drive the opening and closing of the door, overcoming the shortcomings of traditional luggage compartment doors and effectively improving the space utilization rate of the luggage compartment.

[0003] The Chinese patent with application number 202020286226.3 has the following drawbacks: First, the electric suction lock uses a direct-drive motor, and there is no self-locking mechanism after the hatch is closed. It still relies on the worm gear and turbine mechanism inside the actuator motor to tighten the lock. Under the action of the hatch rubber, the weight of the hatch, and the reaction force of the spring inside the lock, the gears inside the actuator motor wear out quickly, have a short lifespan, and the locking is unreliable. Second, the hatch unlocking / locking conversion structure is complex, and the locking is achieved by relying solely on the self-suction lock to drive two locking mechanisms, which leads to unreliable hatch locking, poor sealing, and water leakage when exposed to water. Third, the hatch cannot be closed by operating the door lock handle and must be done with the help of the instrument panel or remote control, which is not convenient to use. Utility Model Content

[0005] To solve the above problems, this utility model is achieved through the following technical solution:

The rotating arm, balance bar, door body, and vehicle body form a three-dimensional four-bar linkage. It also includes a gas strut and an electric actuator. One end of the gas strut is hinged to the vehicle body, and the other end is hinged to the rotating arm. A hinge seat is fixedly installed on the rotating arm, and the gas strut and the rotating arm are hinged at the hinge seat. The fixed part of the electric actuator is hinged to the vehicle body, and the output rod of the electric actuator is hinged to the rotating arm. The electric actuator is electrically connected to the controller.

[0014] The signal-equipped door lock includes a flip cover, on the inside of which an unlocking lever is fixedly connected, the unlocking lever being correspondingly configured with a locking / unlocking cam; it also includes a lock cylinder lever connected to a key, the lock cylinder lever being connected to a lever, the lever being connected to a double-acting cylinder, the other end of the double-acting cylinder being connected to the locking / unlocking cam via a motion conversion mechanism, the locking / unlocking cam being drivenly connected to unlocking gears, the unlocking gears being two meshing unlocking gears, each unlocking gear being connected to a connecting buckle, and each connecting buckle being connected to a first lock lever.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, an electric sliding hatch includes a signal door lock 12. The two ends of the signal door lock 12 are respectively connected to two lower locking mechanisms 13 on the left and right via a first locking lever 11. Each lower locking mechanism 13 is engaged with a lower locking contact 14. Each lower locking mechanism 13 is then connected to its own signal upper locking mechanism 5 via a second locking lever 16. Each signal upper locking mechanism 5 is engaged with an upper locking contact 4. Each upper locking contact 4 is connected to a pull-wire motor 2 via a pull wire.

[0034] This patent application includes two lower locking devices 14 (left and right) and two upper locking devices 4 (left and right). Both the upper and lower locking devices 4 and 14 are fixedly connected to the vehicle body. A signal-equipped locking mechanism 5 and a lower locking mechanism 13 are fixedly connected to the door body 15. The upper locking devices 4 engage with the signal-equipped locking mechanism 5, and the lower locking devices 14 engage with the lower locking mechanism 13, ensuring the door body 15 is securely fixed to the vehicle body. Thus, the signal-equipped door lock 12, through the arrangement of the first locking rod 11 and the second locking rod 16, enables the simultaneous operation of the lower locking mechanism 13 and the signal-equipped locking mechanism 5, resulting in a compact and well-organized structure.

[0035] Furthermore, such as Figure 4 , Figure 5 , Figure 6 As shown, the signal door lock 12 includes a flip cover 121, on the inner side of which an unlocking lever 127 is fixedly connected. The unlocking lever 127 is correspondingly arranged with a locking / unlocking cam 126. It also includes a lock cylinder lever 123 connected to the key. The lock cylinder lever 123 is connected to a lever 1212, which is connected to a double-acting cylinder 124. The other end of the double-acting cylinder 124 is connected to the locking / unlocking cam 126 through a motion conversion mechanism 125. The locking / unlocking cam 126 is connected to an unlocking gear 129. The unlocking gear 129 consists of two meshing unlocking gears 129. A connecting buckle 1210 is connected to each unlocking gear 129, and each connecting buckle 1210 is connected to a first lock lever 11.

[0036] Furthermore, the lever 1212 is provided with an elongated hole, and the double-acting cylinder 124 is provided with a first protrusion 1211, which is located within the elongated hole. It should be noted that the first protrusion 1211 is located on the cylinder body of the double-acting cylinder 124.

[0037] A contact switch 122 is provided on the rear side of the flip cover 121, and the contact switch 122 is electrically connected to the controller 6. When the flip cover 121 is rotated downwards (closed), the contact switch 122 is triggered to actuate. In this way, in this utility model, the signal door lock 12 adds a closing signal to the controller 6, realizing that the sliding door can be electrically closed via the door lock handle, improving the convenience of use.

[0038] Furthermore, the signal door lock 12 is connected to an unlocking motor 8 via an unlocking cable. The unlocking cable is connected to an unlocking conversion bracket 10, which is fixed to the door body 15. The unlocking cable drives the lower pull rod through the conversion bracket 10, and the other end of the pull rod is connected to another connecting buckle 1210 on 129.

[0039] Furthermore, the left and right upper locking contacts have the same structure, such as... Figure 7 , Figure 8 , Figure 9 As shown, each includes a first pull member 41 connected to the pull wire 42. The other end of the first pull member 41 is connected to a second pull member 43 via a first hinge shaft 431. The other end of the second pull member 43 is connected to a third pull member 45. The other end of the third pull member 45 is provided with a locking pin 451, which slides in a limiting groove 461. A spring 44 is provided on the first hinge shaft 431.

[0040] Specifically, the first pull member 41 is provided with a buckle 413 connected to the pull line 42, and a strip hole 411 is provided on the first pull member 41. A locking post 412 is provided in the strip hole 411, and a locking block is provided at the top of the locking post 412 to limit the movement. The locking post 412 is fixed on the base plate 46. That is to say, when the pull line 42 pulls the first pull member 41, the maximum movement distance of the first pull member 41 is the length of the strip hole 411.

[0041] The second pull member 43 is provided with a first hinge shaft 431, a second hinge shaft 433 and a pin 432. The second pull member 43 is hinged to the first pull member 41 through the first hinge shaft 431, and the second pull member 43 is hinged to the third pull member 45 through the second hinge shaft 433. The pin 432 is connected to the base plate 46, that is, the pin 432 can only rotate and cannot swing, and does not produce displacement.

[0042] One end of the third pull member 45 is hinged to the second pull member 43 via the second hinge shaft 433, and the other end of the third pull member 45 is provided with a locking pin 451. The locking pin 451 slides in the limiting groove 461, which is provided on the base plate 46. That is, the movement trajectory of the end of the third pull member 45 with the locking pin 451 is the length of the limiting groove 461.

[0043] One end of the spring 44 is fixed to the first hinge shaft 431, and the other end is connected to the end of the bottom 46.

[0044] During operation, the pull wire 42 moves upward, the first pull member 41 moves upward, and the first hinge shaft 431 and the second hinge shaft 433 in the second pull member 43 swing upward. The second hinge shaft 433 drives one end of the third pull member 45 upward, thus causing the other end of the third pull member 45 to move to the left. Figure 7 That is, the locking pin 451 moves to the leftmost end of the limiting groove 461. The reverse is also true.

[0045] When the locking stop 4 is pulled into position by the cable 42, i.e., when the door is closed, the cable 42 only needs to overcome the tension of the spring 44 to lock the locking stop 451. Since it has passed the structural dead point, the force applied to the locking stop 451 by the door body 15 and the rubber on the vehicle body alone cannot pull the locking stop outward, thus ensuring reliable locking and preventing the locking stop cable motor 2 from being continuously subjected to a large tension that could damage the motor.

[0046] Additionally, it should be noted that the electric push rod 1, the locking pull-wire motor 2, the signal locking machine 5, the unlocking motor 8, and the signal door lock 12 are all connected to the controller 6 via wiring harnesses. The housing of the controller 6 is fixed to the vehicle body; the entire vehicle provides power to the controller 6.

[0047] Generally, a swing arm 7 is connected to the door body 15. The swing arm 7 includes a crossbar, with curved arms connected to both ends of the crossbar. The curved arms on both sides are hinged to the door body 15. One end of the stabilizer bar 9 is hinged to the door body 15, and the other end is hinged to the vehicle body. Thus, the swing arm 7, stabilizer bar 9, door body 15, and vehicle body form a three-dimensional four-bar linkage mechanism, ensuring that the mechanism can open and close normally. This is conventional technology. Additionally, as... Figure 10As shown, this utility model also includes a gas support 3 and an electric actuator 1. One end of the gas support 3 is hinged to the vehicle body, and the other end is hinged to the rotating arm 7. A hinge seat 17 is fixedly installed on the rotating arm 7, and the gas support 3 and the rotating arm 7 are hinged at the hinge seat 17. The fixed part of the electric actuator 1 is hinged to the vehicle body, and the output rod of the electric actuator 1 is hinged to the rotating arm 7. As shown in the figure, during the closing process of the door body 15, the electric actuator 1 does not pass through the structural dead point during the entire movement of the rotating arm 7, ensuring that the electric actuator 1 rotates only in one direction when opening or closing. The gas support 3 passes through the structural dead point of the rotating arm when the rotating arm 7 is closed, that is, after the door is closed, the gas support 3 provides a continuous closing force (a counterclockwise rotational force), ensuring that the door body 15 closes reliably. In this way, the electric actuator 1 and the gas support 3 ensure that the door body 15 does not fall when opening and provides a continuous tension force when closing.

[0048] The working principle of this utility model is as follows:

[0049] The door lock is opened by rotating the key, which rotates the lock cylinder lever 123, causing the double-acting cylinder 124 to move axially. This movement is then transmitted through the motion conversion mechanism 125, which rotates the locking / unlocking cam 126. During unlocking, the flip cover 121 moves upward, and the unlocking lever 127 moves downward, contacting the locking / unlocking cam 126 and thus rotating the unlocking gear 129. The unlocking gear 129 then moves the first lock lever 11. The movement of the first lock lever 11 then unlocks the lower locking mechanism 13 and the signal-equipped locking mechanism 5. Upon receiving the unlocking signal from the signal-equipped locking mechanism 5, the controller 6 issues a command to drive the electric push rod 1. The rotating arm 7 and the door body 15 open to their maximum position under the drive of the electric push rod 1. Simultaneously, the controller 6 issues a command to reverse the locking contact pull cord motor 2, causing the pull cord 42 to extend. Under the extension of the pull cord 42 and the tension of the spring 44, the locking contact 4 pushes out the locking contact pin 451, preparing for the next closing action.

[0050] When the door lock is operated to close, the flip cover 121 rotates downward around the central axis, triggering the contact switch 122 to close. After receiving the signal from the contact switch 122, the controller 6 issues a command to drive the electric push rod 1 to work, which drives the rotating arm 7 and the door body 15 to close. When the signal locking mechanism 5 fixed to the door body 15 engages with the locking contact 4, the controller 6 receives a signal and drives the locking contact pull motor 2 to rotate forward, which drives the locking contact pin 451 to retract, pulling the door body 15 to the closed position.

[0051] The opening process is achieved by operating the central control panel / remote control. The central control panel / remote control button issues an opening command. After receiving the signal, the controller 6 drives the unlocking motor 8 to work. The unlocking motor 8 pulls the unlocking cable, and under the action of the unlocking conversion bracket 10, the force is transmitted to the unlocking gear 129 of the signal door lock 12. Figure 4The connecting buckle 1210 in the middle of the unlocking gear 129 is used to pull the first lock lever 11, thereby driving the lower locking mechanism 13 and the signal locking mechanism 5 to unlock. The subsequent actions are the same as the operation of the signal door lock 12 to achieve the opening process.

[0052] The closing process is achieved by operating the central control panel / remote control. The central control panel / remote control button sends a closing command. After receiving the signal, the controller 6 sends a command to drive the electric push rod 1 to work. The subsequent actions are the same as the closing process achieved by operating the door lock 12 with a signal.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
