Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a structure for a bus operating door cover. Background Technology

[0002] Buses typically have control door covers for their fuel filler caps, charging ports, and other operating ports. These covers protect the ports by opening and closing. In existing technology, the control door cover structure mainly consists of a mounting frame and a cover plate that rotates on the mounting frame. The cover plate is locked to the mounting frame by engaging a locking rod of a locking device located on the mounting frame through a locking hole on its upper part. However, in the existing control door cover structure, the cover plate may sag due to its own weight during long-term rotation, causing the locking hole on the cover plate to fail to align accurately with the locking rod of the locking device, thus preventing the cover plate from opening and closing properly.

[0003] To address the aforementioned problems, this utility model provides improvements. Utility Model Content

[0004] This utility model proposes a bus operating door cover structure, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A bus operating door cover structure includes a mounting frame, a cover plate, and a locking device. The cover plate is rotatably mounted on the mounting frame, and the locking device is mounted on the mounting frame. A limit block is provided on the inner wall of the free end of the cover plate. Two limit posts are provided on the mounting frame, each located on the swing path of the limit block. The limit block has a lock hole that mates with the locking rod of the locking device and two limit cavities located above and below the lock hole that match the limit posts.

[0007] Preferably, two snap-fit ​​blocks are symmetrically formed on the surface of the limiting block facing the cover plate. An insertion gap is formed between the snap-fit ​​blocks and the limiting block, and a limiting protrusion is formed on the surface of the snap-fit ​​blocks facing the limiting block. The cover plate has two snap-fit ​​holes for the snap-fit ​​blocks to pass through and two limiting holes located on one side of the two snap-fit ​​holes respectively. After the snap-fit ​​blocks pass through the snap-fit ​​holes, the limiting protrusions slide towards the limiting holes and snap into the limiting holes, and the cover plate is inserted into the insertion gap.

[0008] Preferably, a reinforcing plate is formed on the surface of the limiting block facing the cover plate, and a reinforcing hole is provided on the cover plate for the reinforcing plate to pass through. The reinforcing plate passes through the reinforcing hole and abuts against the cover plate when the limiting protrusion is engaged in the limiting hole.

[0009] Preferably, a hinge plate is rotatably mounted on the inner wall of the mounting frame via a rotating shaft. An elongated hole is provided on one side of the hinge plate on the mounting frame. An arc segment is formed on the hinge plate, passing through the elongated hole and centered on the axis of the rotating shaft. The arc segment passes through the elongated hole and is bent to form a connecting segment, which is fixedly connected to the cover plate.

[0010] Preferably, the cover plate is composed of an inner side plate and an outer side plate, and the connecting section is inserted between the inner side plate and the outer side plate and welded to the inner side plate.

[0011] Preferably, the rotating shaft is fixedly mounted on the hinge plate and a cylindrical damping pile is fixedly connected to the end of the rotating shaft. A damping protrusion is formed on the circumferential surface of the damping pile. An elastic plate located on one side of the damping pile and abutting against the damping pile is fixedly connected to the inner wall of the mounting frame. A limiting groove matching the damping protrusion is provided on the elastic plate.

[0012] Preferably, a support plate is fixedly installed on the mounting frame on one side of the hinge plate. A first sliding pin is rotatably installed on the support plate, and a second sliding pin is rotatably installed on the rotating shaft. An installation window is provided on the hinge plate. The first sliding pin passes through the installation window and is inserted into a sliding cavity provided on the first sliding pin. Springs are sleeved on the first and second sliding pins, with their two ends respectively abutting against the first and second sliding pins.

[0013] In summary, the beneficial effects of this utility model are as follows: before the locking rod of the locking device is inserted into the lock hole, the limiting post is first inserted into the limiting cavity. The action of the limiting post inserting into the limiting cavity provides a guiding effect for the action of the cover plate swinging towards the mounting frame, ensuring that the locking rod of the locking device can be accurately aligned with the lock hole and inserted into the lock hole to cooperate with the lock hole to lock the cover plate and the mounting frame, ensuring the stability of the cover plate and the mounting frame when opening and closing. Furthermore, after the limiting post is inserted into the limiting cavity, it provides longitudinal support for the cover plate relative to the mounting frame, preventing the locking rod of the locking device from getting stuck in the lock hole due to the cover plate falling due to its own weight.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] As shown in the figure, a bus operating door cover 2 structure includes a mounting frame 1, a cover 2, and a locking device 3. The cover 2 is rotatably mounted on the mounting frame 1, and the locking device 3 is mounted on the mounting frame 1 with its locking rod passing through the mounting frame 1. A limiting block 4 is provided on the inner wall of the free end of the cover 2. The mounting frame 1 is provided with two limiting posts 5 located on the swing path of the limiting block 4 and on the upper and lower sides of the locking rod of the locking device 3, respectively. The limiting block 4 has a lock hole 41 that cooperates with the locking rod of the locking device 3 and two limiting cavities 42 located on the upper and lower sides of the lock hole 41 that match the limiting posts 5, respectively.

[0025] Specifically, the structure of the limiting block 4 on the cover plate 2 is as follows: two locking blocks 43 are symmetrically formed on the surface of the limiting block 4 facing the cover plate 2. An insertion gap is formed between the locking block 43 and the limiting block 4, and a limiting protrusion 44 is formed on the surface of the locking block 43 facing the limiting block 4. The cover plate 2 has two locking holes 211 for the locking block 43 to pass through and two limiting holes 212 located on one side of the two locking holes 211 respectively. After the locking block 43 passes through the locking hole 211, the limiting protrusion 44 slides towards the limiting hole 212 and locks into the limiting hole 212, and the cover plate 2 is inserted into the insertion gap, and the limiting protrusion 44 locks into the cover plate 2. The engagement of the locking block 43 with the locking hole 212 limits the sliding of the locking block 43 relative to the cover plate 2, and thus limits the sliding of the locking block 4 relative to the cover plate 2. After the cover plate 2 is inserted into the insertion gap between the locking block 4 and the locking block 43, it limits the forward and backward displacement of the locking block 4 and the cover plate 2, thereby achieving a fixed connection between the locking block 4 and the cover plate 2. Through the above structure that achieves a fixed connection between the locking block 4 and the cover plate 2, while ensuring the stability of the connection between the locking block 4 and the cover plate 2, the locking block 4 can be easily disassembled and assembled with the cover plate 2, which facilitates the assembly of the locking block 4 and the replacement of the worn locking block 4 later.

[0026] In the above structure, when the cover plate 2 swings towards the mounting frame 1 to close the operating opening of the mounting frame 1, before the locking rod of the locking device 3 is inserted into the lock hole 41, the limiting post 5 is first inserted into the limiting cavity 42. The action of the limiting post 5 inserting into the limiting cavity 42 provides a guiding effect for the action of the cover plate 2 swinging towards the mounting frame 1, ensuring that the locking rod of the locking device 3 can be accurately aligned with the lock hole 41 and inserted into the lock hole 41 to cooperate with the lock hole 41 to lock the cover plate 2 and the mounting frame 1 (the locking device 3 is an elastic locking device, and its main working principle is to cooperate with the lock hole 41 through the rotation of the locking rod during elastic extension and contraction. The specific structure and working principle are existing technologies and will not be described in detail here). This ensures the stability of the cover plate 2 and the mounting frame 1 when opening and closing, and after the limiting post 5 is inserted into the limiting cavity 42, it provides longitudinal support for the cover plate 2 relative to the mounting frame 1, preventing the cover plate 2 from falling due to its own weight and causing the locking rod of the locking device 3 to get stuck in the lock hole 41.

[0027] Furthermore, based on the above structure, a reinforcing plate 45 is formed on the surface of the limiting block 4 facing the cover plate 2. The cover plate 2 has a reinforcing hole 213 through which the reinforcing plate 45 can pass. When the reinforcing plate 45 passes through the reinforcing hole 213 and is engaged in the limiting hole 212 by the limiting protrusion 44, it abuts against the cover plate 2. The contact between the reinforcing plate 45 and the cover plate 2 strengthens the stability of the limiting block 4 fixedly connected to the cover plate 2.

[0028] Furthermore, based on the above structure, a hinge plate 6 is rotatably mounted on the inner wall of the mounting frame 1 via a rotating shaft 7. The mounting frame 1 has an elongated hole 11 located on one side of the hinge plate 6. An arc segment 61 is formed on the hinge plate 6, passing through the elongated hole 11 with the axis of the rotating shaft 7 as its center. After passing through the elongated hole 11, the arc segment 61 is bent to form a connecting segment 62. The connecting segment 62 is fixedly connected to the cover plate 2. In the above structure, the hinge plate 6 is located inside the mounting frame 1. After the mounting frame 1 is installed on the vehicle, the hinge plate 6 can be hidden, making the overall structure of this operating door cover plate 2 more aesthetically pleasing. The movement of the arc segment 61 through the elongated hole 11 allows the cover plate 2 to swing relative to the mounting frame 1. The elongated hole 11 constrains the sway of the hinge plate 6, preventing the cover plate 2 from falling due to its own weight, thereby ensuring the stability and durability of the cover plate 2 when opening and closing.

[0029] Furthermore, based on the above structure, the cover plate 2 is composed of an inner side plate 21 and an outer side plate 22. The connecting section 62 is inserted between the inner side plate 21 and the outer side plate 22 and welded to the inner side plate 21. The snap-fit ​​hole 211, the limiting hole 212 and the reinforcing hole 213 are opened on the inner side plate 21. Through the above structure, the connection welding point between the hinge plate 6 and the cover plate 2 is set on the inner side plate 21, ensuring the aesthetics of the outer surface of the outer side plate 22, thereby ensuring the overall aesthetics of this operating door cover plate 2 structure.

[0030] Furthermore, based on the above structure, the rotating shaft 7 is fixedly mounted on the hinge plate 6, and a cylindrical damping pile 8 is fixedly connected to the end of the rotating shaft 7. A damping protrusion 81 is formed on the circumferential surface of the damping pile 8. An elastic plate 9 is fixedly connected to the inner wall of the mounting frame 1, located on one side of the damping pile 8 and abutting against it. A limiting groove 91 matching the damping protrusion 81 is provided on the elastic plate 9. When the cover plate 2 drives the hinge plate 6 to rotate on the mounting frame 1, the hinge plate 6 drives the rotating shaft 7 to rotate on the mounting frame 1, and the rotating shaft 7 drives the damping pile 8 to rotate. The damping pile 8 rotates... The process causes the damping protrusion 81, which is in contact with the elastic plate 9, to rotate, thereby causing the elastic plate 9 to deform. The elastic force generated by the deformation of the elastic plate 9 provides damping for the rotation of the damping pile 8, and in turn provides damping for the swing of the cover plate 2 in the mounting frame 1, preventing the cover plate 2 from colliding with the mounting frame 1 during the swing and generating noise, thus improving the user experience of this operating door cover plate 2 structure. After the cover plate 2 is locked with the mounting frame 1, the damping protrusion 81 is inserted into the limiting groove 91, thereby limiting the rotation of the damping pile 8 and the cover plate 2, and strengthening the stability of the cover plate 2 after it is locked with the mounting frame 1.

[0031] In addition, based on the above structure, a support plate 12 is fixedly installed on the mounting frame 1, located on one side of the hinge plate 6. A first sliding pin 13 is rotatably installed on the support plate 12, and a second sliding pin 14 is rotatably installed on the rotating shaft 7. An installation window 63 is opened on the hinge plate 6. The first sliding pin 13 passes through the installation window 63 and is inserted into the sliding cavity opened on the first sliding pin 13. Springs 15 are sleeved on the first sliding pin 13 and the second sliding pin 14, with their two ends respectively abutting against the first sliding pin 13 and the second sliding pin 14. When the locking rod of the locking device 3 is disengaged from the lock hole 41, the first sliding pin 13 and the second sliding pin 14 slide away from each other under the elastic force of the spring 15, causing the second sliding pin 14 to push the hinge plate 6 to swing, thereby causing the cover plate 2 to automatically swing a certain angle away from the mounting frame 1. This facilitates the subsequent swinging of the free end of the cover plate 2 to fully open the operating port of the mounting frame 1, thus facilitating the operation of opening and closing the cover plate 2.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
