Description

Technical Field

[0001] The utility model relates to the technical field of bus front enclosures, in particular to a bus front enclosure assembly. Background Art

[0002] The front panel inspection doors of existing buses mostly adopt an upward flip structure design, that is, the upper end of the inspection door is hinged on the front panel frame, and the lower end is locked on the front panel frame. For example, the Chinese utility model patent with the authorization announcement number CN206664729U discloses a flip-up front panel door for pure electric buses, the upper end of which is hinged on the front panel reinforcement beam through a panel hinge, and the lower end is locked by a panel lock, so that the front panel door can rotate around the upper end after the lower end is unlocked, thereby realizing the opening of the front panel door.

[0003] In order to facilitate the opening of the inspection door, a handle is usually set at the lower end of the inspection door so that the operator can open the inspection door from the lower end. The prior art usually includes two types of handle designs: ① In the early stage of appearance design, a groove is specially set under the inspection door to reserve space for the inspection door to open; ② A special handle component similar to a door handle is installed on the inspection door. In the first design scheme mentioned above, the groove structure will destroy the integrity of the front wall of the bus and affect the appearance effect. In the second scheme, on the one hand, it is necessary to use additional door handle parts, and on the other hand, the shape of the door handle parts needs to be matched and designed according to the front wall skin curve of the bus, which makes the manufacturing cost higher. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a bus front panel assembly, which has a simple structure, a convenient opening of the inspection door, a strong overall shape, and does not affect the visual effect of the bus front panel.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A passenger car front panel assembly includes a skin component, an inspection door, a movable latch and an elastic connector, wherein the inspection door is arranged above the skin component, a mounting slot is formed between the skin component and the inspection door, the movable latch is arranged in the mounting slot, and the elastic connector can undergo axial expansion and contraction and radial bending; the skin component includes a vertically arranged main body plate, a first mounting plate laterally connected to the upper end of the main body plate, and a second mounting plate laterally connected to the inner side surface of the main body; the movable latch includes a configuration plate and a connecting hinge, the lower end of the configuration plate is movably connected to the first mounting plate via the connecting hinge, and the upper end of the configuration plate forms an inner connecting plate extending toward the inner side of the front panel; the upper and lower ends of the elastic connector are fixedly connected to the inner connecting plate and the second mounting plate, respectively.

[0007] In the present invention, the lower end of the movable hand is connected to the skin component by a hinge, so that the upper end of the movable hand can be pushed into the interior of the front enclosure, thereby exposing the installation slot, and the position corresponding to the installation slot of the lower end of the inspection door forms an operation site, through which the fixing mechanism of the inspection door and the vehicle body can be released and the inspection door can be opened, so as to facilitate the inspection of the mechanical structure inside the front enclosure, and the upper end of the movable hand is connected to the inner side of the skin component by an elastic connector, and the elastic connector can keep the movable hand covering the installation slot when the movable hand is not subjected to a thrust, on the one hand, the integrity of the front enclosure structure can be ensured in a non-inspection state to avoid exposing the installation slot, and on the other hand, the movable hand can be restored by itself after the thrust on the movable hand is removed in the inspection state, so as to avoid increasing the inspection workload. In order to facilitate the operator to handle the operation site, the movable hand should be able to form an operation area with a width of at least 20 mm from top to bottom after being turned inward, so as to ensure that the operator's fingers can be inserted into the back side of the inspection door and release the fixing mechanism of the inspection door and the vehicle body.

[0008] Furthermore, the bus front enclosure assembly also includes a limit support seat arranged inside the installation slot, and the inner connecting plate is connected with a limit piece which can abut against the lower side of the limit support seat.

[0009] The limiting piece and the limiting support can prevent the movable buckle hand from turning outward, thereby ensuring the normal operation of the movable buckle hand.

[0010] Furthermore, a spacing gap is formed between the upper side surface of the inner connecting plate and the lower end portion of the inspection door, through which the movable buckle handle can rotate and move.

[0011] Furthermore, the skin component also includes an inner base plate, which includes an upper plate body that is fitted and connected to the inner side of the first mounting plate and a lower plate body that is fitted and connected to the inner side of the main body plate, the configuration plate is hingedly connected to the upper plate body, and the second mounting plate is fixedly connected to the lower plate body.

[0012] Furthermore, the lower side of the inner connecting plate is connected to a mounting base, the upper end of the elastic connecting member is short-circuited with the lower end of the mounting base, and the limiting support is fixedly connected to the side of the mounting base.

[0013] Furthermore, the bus front panel assembly also includes a safety plate transversely arranged between the skin component and the inspection door, the safety plate protrudes outward relative to the skin component and the inspection door, and the middle part of the safety plate is broken to form the installation groove.

[0014] In order to ensure that the movable buckle is consistent with the shape of the front panel of the bus, the configuration plate of the movable buckle can be directly cut from the middle of the safety plate. The position where the safety plate is cut naturally forms an installation groove. Subsequently, only further processing of the configuration plate is required to obtain a movable buckle consistent with the overall configuration of the front panel. The manufacturing cost and processing difficulty are low.

[0015] Furthermore, the configuration plate comprises an outer convex plate connected to the outer end of the inner connecting plate and protruding outward relative to the skin component and the inspection door, and the configuration of the outer convex plate is consistent with that of the safety plate.

[0016] Furthermore, the lower end of the outer convex plate is connected to an inner extension plate extending toward the outer end of the first mounting plate, and a spacing is left between the inner extension plate and the first mounting plate.

[0017] Furthermore, when the limiting support is in contact with the limiting member, the elastic connecting member is in an elastically compressed state.

[0018] Furthermore, the elastic connecting member is composed of a spring, and the upper end and the lower end of the elastic connecting member are fixedly connected to the inner connecting plate and the second mounting plate through a bolt structure.

[0019] The bolt structure can change the compression amount of the spring by rotating the nut, thereby changing the preload force provided by the spring when the limit support abuts against the limit member, and controlling the preload force within an appropriate range, which can not only ensure that the movable buckle is not blown by convection during driving, but also ensure that the movable buckle is easy to be pushed open when the inspection door is opened.

[0020] In summary, the application of the utility model can achieve the following beneficial effects:

[0021] 1. The utility model can expose the installation notch by applying a thrust to the movable buckle, and the staff can operate the inspection door through the installation notch, release the fixed state of the inspection door and open the inspection door. The movable buckle plays a protective role without affecting the opening of the inspection door, which is convenient for the inspection process.

[0022] 2. When not under maintenance, the movable buckle of the utility model closes the installation slot, which can prevent the installation slot from affecting the overall appearance of the front enclosure.

[0023] 3. The upper end of the movable buckle of the utility model is connected to the elastic connector, which provides pre-tightening pressure while ensuring that the movable buckle can rotate, so that the elastic connector maintains a closed state on the installation slot when not under maintenance.

[0024] 4. In some embodiments, the elastic connector of the utility model can adjust its own compression degree to change the size of the pre-tightening pressure, which can not only ensure that the movable buckle is not blown by convection during driving, but also ensure that the movable buckle can be easily pushed open when opening the inspection door.
