Description

Technical Field

[0001] This invention relates to the field of access door technology, and more specifically to an access door and its application in automobiles. Background Technology

[0002] As a special type of vehicle, the camping vehicle integrates personnel transportation and rest. It effectively solves the contradiction between the limited passenger capacity of all-sleeper vehicles and the inconvenience of rest in all-seat vehicles, perfectly meeting the needs of military and police systems and improving the comfort of transportation and camping.

[0003] Among them, Chinese patent application number 201921490936.1 discloses an insect-proof vehicle door and window device for outdoor camping vehicles. It includes a door, a self-locking head, plastic, glass, hinge, mesh frame, door frame, mesh wire, handle, self-opening device, air spray device, and vent. It works by opening the door simultaneously triggering the extension and retraction of the door frame rod and mesh frame rod, triggering a switch to power the air compressor, causing the nozzle to spray a strong horizontal airflow to obstruct insects and prevent them from flying into the vehicle.

[0004] Furthermore, Chinese patent document CN103089080B discloses a passageway lock, including a lock body and a drive device. The lock body includes a housing, a fixed seat inside the housing, a drive shaft through hole on the fixed seat, and a latch drive shaft that can reciprocate along the drive shaft through hole.

[0022] Please see Figure 1As shown, this invention discloses a passageway door and its application in automobiles, which can improve the problems of low strength and poor stability of existing automobile passageway doors. Specifically, the passageway door is connected to the vehicle body and may include a door body 100, a door frame 200, and a lock cylinder structure 310 disposed between the door body 100 and the door frame 200. The door body 100 and the door frame 200 are connected in an openable and closable manner, and the specific opening and closing direction can be determined according to actual needs. It is understood that for automobiles including the passageway door, the door frame 200 is fixedly connected to the vehicle body. The door frame 200 and the vehicle body are typically integrally formed.

[0023] Please see Figures 1 to 11 As shown, in one embodiment, the passageway door may include a door body 100 and an outer skin 110 disposed on the outer side of the door body 100, which enhances the strength of the door body 100. It should be noted that for the door body 100, one side of the outer skin 110 can be defined as the outer side, and the side away from the outer skin 110 can be defined as the inner side. The outer side of the door body 100 is arc-shaped, which further enhances the strength of the door body 100.

[0024] In one embodiment, a cavity is formed between the door body 100 and the outer skin 110, and multiple support frames are provided within the cavity. The support frames are interconnected to construct the frame structure of the passage door. The support frames are fixedly connected to both the door body 100 and the outer skin 110, thereby effectively improving the strength of the passage door. The support frames may be constructed using aluminum square tubing and may also have a galvanized coating, further extending their service life. The diagonal error of the door body 100 is within millimeters. Reducing the diagonal error of the door body 100 improves its strength. Multiple wire holes are provided on the support frames, allowing wire harnesses to pass through. A lock box cavity is also provided within the door body 100, and the lock box connecting the passage door and the door body 100 may be located within this cavity.

[0025] In one embodiment, since the outer skin 110 and the door body 100 are fixedly connected, the connection can be made by bonding with structural adhesive. Meanwhile, a sealing strip is provided between the outer skin 110 and the supporting frame, which improves the connection between the supporting frame and the outer skin 110.

[0026] It should be noted that since the outer skin 110 is located on the outside of the door body 100, and the outside of the door body 100 is curved, the misalignment between the outer skin 110 and the door body 100 must be less than millimeters to improve the connection. Simultaneously, the outer radius of the door body 100's curvature is greater than 12000 millimeters, and the door body 100 can be constructed using sheet metal. Therefore, when the outer radius of the sheet metal door body 100's curvature is greater than 12000 millimeters, the strength of the door body 100 during actual use can be effectively improved, thereby enhancing the stability of the passageway door. An internal handle 300 is also connected to the inside of the door body 100, and the internal handle 300 is connected to the door body 100. The internal handle 300 facilitates the opening and closing of the door body 100.

[0027] In one embodiment, a hinge plate 102 is provided on one side of the door body 100, and a galvanized anti-rust layer is provided on the hinge plate 102. The galvanized anti-rust layer improves the service life of the hinge plate 102. Simultaneously, the hinge plate 102 and the inner side of the door body 100 are set at an angle of 100°. Specifically, a rotating member 103 is also connected between the door body 100 and the door frame 200, enabling the opening and closing of the door body 100 and the door frame 200. The rotating member 103 may include a limiting part 1030 and a rotating part 1031, which are hinged together. The limiting part 1030 is located on the door frame 200, and the rotating part 1031 is fixedly connected to the hinge plate 102. The rotating component 103 is made of injection molding, and the outer layer of the rotating component 103 is also provided with a galvanized layer to improve the performance of the rotating component 103. At the same time, by setting the hinge plate 102 and the inner side of the door at an angle, the stability of the passage door during the opening and closing process can be improved.

[0028] Please see Figure 6 As shown, in one embodiment, a protective plate 211 may be connected to the door frame 200, and a sealing strip 212 is connected to the protective plate 211. The sealing strip 212 provides a seal between the door body 100 and the door frame 200.

[0029] Please see Figure 1 and Figure 9 , Figure 10 as well as Figure 11As shown, in one embodiment, the lock cylinder structure 310 is located between the door body 100 and the door frame 200, and is used to lock the door body 100 and the door frame 200. Specifically, the lock cylinder structure 310 may include a connecting frame 337, a first lock block 336, a rotating block 331, and a mounting plate 213. A connecting plate 338 is fixedly connected to the connecting frame 337, and the connecting plate 338 is fixedly connected to the door body 100. The first lock block 336 is rotatably connected to the connecting frame 337 via a rotating shaft 335, and the first lock block 336 has a lock hole. The rotating block 331 is located on the connecting plate 338, and the rotating block 331 and the first lock block 336 are connected by a transmission connection. For example, the rotating shaft 335 and the rotating block 331 are driven by a gear pair. Therefore, when the rotating block 331 rotates, it can simultaneously drive the rotating shaft 335 and the first lock block 336 connected to the rotating shaft 335 to rotate. Mounting plate 213 is located on door frame 200, and locking rod 214 is fixedly connected to mounting plate 213. Therefore, locking rod 214 can be engaged in the keyhole, and can be disengaged from the keyhole by rotating the first locking block 336.

[0030] A drive box 330 is connected to the door body 100, located within the cavity formed between the door body 100 and the outer skin 110. The drive box 330 may include a drive disc 3301, which is kinetically connected to the lock cylinder structure 310. Specifically, the drive box 330 is used to unlock the lock cylinder structure 310 and the locking rod 214. The drive box 330 can be customized according to actual needs. The disc is allowed to rotate within the drive box 330, and the drive disc 3301 is connected to the lock cylinder structure 310. Therefore, by driving the drive disc 3301 to rotate, the lock cylinder structure 310 and the locking rod 214 are unlocked.

[0031] Specifically, a first connecting rod 332 is provided between the drive box 330 and the lock cylinder structure 310. One end of the connecting rod is hinged to the drive disc 3301, and the other end is hinged to the rotating block 331 in any of the lock cylinder structures 310. Therefore, the drive box 330 drives the rotating block 331 to rotate via the first connecting rod 332.

[0032] In one embodiment, multiple sets of lock cylinder structures 310 are provided, and these multiple sets of lock cylinder structures 310 are driven simultaneously. Specifically, a second connecting rod 333 is provided between adjacent lock cylinder structures 310, and the end of the second connecting rod 333 is hinged to the rotating block 331 located on the lock cylinder structure 310. Therefore, the simultaneous driving of multiple sets of lock cylinder structures 310 is achieved through the second connecting rod 333.

[0033] It should be noted that the built-in handle 300 is pivotally connected to the door body 100, and a third connecting rod 334 is also provided between the built-in handle 300 and any of the lock cylinder structures 310. One end of the third connecting rod 334 is connected to the built-in handle 300, and the other end is connected to the rotating block 331 on any of the lock cylinder structures 310. Therefore, when the built-in handle 300 rotates relative to the door body 100, the rotating block 331 can be driven to rotate via the third connecting rod 334, thereby unlocking the first locking block 336 and the locking rod 214. It is understood that adjacent lock cylinder structures 310 can rotate synchronously via the second locking rod 214.

[0034] Understandably, the rotating block 331 may include a first hinge portion 3310 and a second hinge portion 3311. One end of the first connecting rod 332 is hinged to the first hinge portion 3310, and one end of the second connecting rod 333 is hinged to the second hinge portion 3311. Therefore, the second connecting rod 333 allows the two sets of lock cylinder structures 310 to unlock synchronously.

[0035] In summary, this invention discloses a passageway door and its application in automobiles, which can improve the problems of low strength and poor stability of existing passageway door bodies 100. Specifically, the supporting frame located between the outer skins 110 of the door body 100, and the use of an arc-shaped structure with a radius greater than 12000 mm on the outer side of the door body 100, effectively improve the strength of the door body 100 and the stability of the passageway door during actual use. By setting the hinge plate 102 at an angle to the inner side of the door, the passageway door becomes relatively stable during rotation. Simultaneously, the multiple sets of lock cylinder structures 310 located between the door body 100 and the door frame 200 effectively improve the stability after locking. Therefore, it can effectively improve the problems of complex lock structures and insufficient stability of existing passageway doors after locking.

[0036] Therefore, this invention effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.

[0037] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
