Description

A driver's rear bumper and bus Technical Field

[0001] This application relates to the field of bus technology, specifically to a driver's rear bumper and a bus. Background Technology

[0002] A driver's enclosure is used to isolate the driver's cabin from other spaces within a public transportation vehicle, providing the driver with a relatively independent driving space. This ensures the driver is not disturbed by other passengers while driving, protects the driver from physical attacks, and guarantees a safe and stable driving experience. In related technologies, a driver's enclosure typically consists of a side enclosure extending forward and backward along the left or right side of the driver's seat, and a rear enclosure extending laterally behind the driver's seat. The front end of the side enclosure is close to the dashboard, while the side of the rear enclosure furthest from the side enclosure is close to the vehicle's side panel, thus forming an L-shaped enclosure to separate the driver's cabin from the common areas inside the vehicle. The rear enclosure, on the side furthest from the vehicle's side panel, often has a fixing rod extending from its base to the roof to ensure the stability of the entire enclosure structure.

[0003] For example, the integrated enclosed electric lifting door disclosed in Chinese utility model patent with authorization announcement number CN218343437U has a fixing rod set on the front side of the driver's rear enclosure (i.e., rear enclosure) near the pivot. The top of the fixing rod protrudes out of the side enclosure (i.e., side enclosure) and the rear enclosure and is fixedly connected to the vehicle body. Several fixing crossbars are also set on the fixing rod laterally and are fixedly connected to the inner side of the rear enclosure. The fixing rod and the fixing crossbars are integrally formed by welding. The fixed connection with the vehicle body is achieved through this integral structure of the fixing rod.

[0004] The problem is that the top of the fixing rod extends upwards beyond the upper edge of the side and rear panels, and its top is exposed in the space above the side and rear panels, which takes up space and affects the view. Summary of the Invention

[0005] The purpose of this application is to provide a driver rear bumper to solve the problem in the related art where the top of the fixing rod located on the front side of the rear bumper extends upwards to the upper edge of the side bumper and the rear bumper, and its top is exposed in the space above the side bumper and the rear bumper, which both occupies space and affects the view; this application also aims to provide a bus using a driver rear bumper to solve the above problems.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the application; that is, the described embodiments are only a part of the embodiments of this application, and not all of them. The components of the embodiments of this application described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0036] A basic embodiment of this application provides a bus with a driver's surround at the driver's seat. A top air duct 5 is located at the top of the side panels of the bus. The bus's overall frame includes a roof frame and side panel frames. Figure 1 is a schematic diagram of the outer structure of the driver's surround of a bus according to this application, and Figure 2 is a schematic diagram of the inner structure of the driver's surround of a bus according to this application. As shown in Figures 1-2, the driver's surround includes a rear surround 1 and a side surround 2. The rear surround 1 is located behind the driver's seat, and the side surround 2 is located on the side of the driver's seat. The rear surround 1 and the side surround 2 are hinged together by a pivot 3. The top of the driver's rear surround 1 is raised to form a raised top. The raised top is close to the lower side of the top air duct 5. A clearance hole 52 is provided on the decorative piece 51 on the lower side of the top air duct 5. A hidden fixing bracket 4 is provided at the raised top position, passing upward through the clearance hole 52 and connecting to the overall frame. This hidden fixing bracket 4 is connected to the roof frame to stabilize the rear surround 1. In this structure, the concealed mounting bracket 4 is concealed by the rear bumper 1 and the top air duct 5. In other embodiments, the concealed mounting bracket 4 extends through the clearance hole 52 into the top air duct 5 and connects to the side frame on the vehicle side panel, no longer connected to the roof frame above the top air duct 5. The rear bumper 1 remains stable by connecting the concealed mounting bracket 4 to the side frame.

[0037] Figure 5 is an enlarged schematic diagram of the concealed mounting bracket in Figure 4. Specifically, as shown in Figure 5, the decorative piece 51 is detachably connected to the top air duct 5, and the clearance hole 52 on the decorative piece 51 has a large diameter to allow for easy installation of the concealed mounting bracket 4.

[0038] Figure 3 is a schematic diagram of the outer structure of the concealed fixing frame in this application, Figure 4 is a schematic diagram of the inner structure of the concealed fixing frame in this application, and Figure 6 is a side view of the concealed fixing frame in this application.

[0039] Based on the above embodiments, in an optional embodiment, as shown in Figures 1-6, the front side of the booster top, i.e. the side facing the driver's seat, is provided with a fixing bracket connecting seat 43. The fixing bracket connecting seat 43 is a U-shaped block structure with its opening facing the rear side of the rear bumper. The bottom of the hidden fixing bracket 4 is fixedly connected to the fixing bracket connecting seat 43 to realize the connection between the hidden fixing bracket 4 and the booster top.

[0040] Based on the above embodiments, in an optional embodiment, as shown in Figures 3-6, the front side of the raised top is further provided with a decorative cover 44 to cover the mounting bracket connecting seat 43 and the hidden mounting bracket 4. The decorative cover 44 is a rectangular shell with an open top and rounded edges. The top of the decorative cover 44 is open to allow the hidden mounting bracket 4 to extend upward into the top air duct 5. The top of the decorative cover 44 is higher than the top of the mounting bracket connecting seat 43 and close to the lower side of the top air duct 5 of the bus, and cooperates with the lower side of the top air duct 5. This allows the structure of the mounting bracket connecting seat 43 and the part of the hidden mounting bracket 4 that has not yet extended into the top air duct 5 to be covered and not affected by the external environment, thereby improving the service life of the mounting bracket connecting seat 43 and the hidden mounting bracket 4, and also making it more aesthetically pleasing. Since the top of the decorative cover 44 is close to the lower side of the top air duct 5 of the bus during use and cooperates with the lower side of the top air duct 5, this top can also be called the cooperating top.

[0041] Based on the above embodiments, in an optional embodiment, to better maintain the stability of the rear bumper 1 with the concealed mounting bracket 4, as shown in Figures 1-5, a top crossbeam 11 is provided on the front side of the raised top of the rear bumper 1, extending left and right along the upper edge contour of the rear bumper 1. The mounting bracket connecting seat 43 and the decorative cover 44 are both fixedly connected to the top crossbeam 11, which not only ensures the structural strength of the rear bumper 1 but also improves the stability of the concealed mounting bracket 4. In other embodiments, in addition to the top crossbeam 11, a longitudinal beam extending downward along the height direction of the rear bumper 1 is also provided below the concealed mounting bracket 4. The longitudinal beam is fixedly connected to the mounting bracket connecting seat 43, further enhancing the stability of the rear bumper 1.

[0042] Based on the above embodiments, in an optional embodiment, as shown in Figures 4-5, in order to make it easier to assemble the fixing bracket connecting seat 43 and the hidden fixing bracket 4 and adapt to different installation requirements, the fixing bracket connecting seat 43 and the hidden fixing bracket 4 are adjustable in the vertical direction.

[0043] Based on the above embodiments, in an optional embodiment, considering economic efficiency, at least one of the concealed mounting bracket and the mounting bracket connecting seat is provided with at least one connecting hole, which is configured to allow the concealed mounting bracket and the mounting bracket connecting seat to be adjusted vertically.

[0044] Based on the above embodiments, in one optional embodiment, at least one connecting hole includes one or more elongated holes extending in the vertical direction, or includes multiple holes spaced apart in the vertical direction. As shown in Figures 4-5, the bottom straight section of the concealed mounting bracket 4 is symmetrically provided with two elongated holes 423 extending in the vertical direction. The mounting bracket connecting seat 43 can be fixedly connected at different heights of the elongated holes 423 as needed to connect the mounting bracket connecting seat 43 and the concealed mounting bracket 4, achieving an adjustable connection between the two. In other embodiments, the bottom straight section of the concealed mounting bracket 4 has only one elongated hole 423, and multiple tightening bolts are installed at this elongated hole 423 to achieve an adjustable connection between the mounting bracket connecting seat 43 and the concealed mounting bracket 4. In other embodiments, multiple holes are provided at different heights of the bottom straight section of the concealed mounting bracket 4, and the mounting bracket connecting seat 43 is connected to different holes as needed to achieve an adjustable connection between the mounting bracket connecting seat 43 and the concealed mounting bracket 4.

[0045] In this embodiment, the connecting hole between the connecting bracket and the concealed bracket is located on the concealed bracket. However, it should be understood that the connecting hole can also be located on the connecting bracket or both. The connecting hole only needs to enable the connection between the connecting bracket and the concealed bracket; this application does not limit its specific location. Furthermore, this application does not specifically limit the number, shape, or arrangement of the connecting holes, as long as they allow for adjustable connection between the connecting bracket and the concealed bracket in the vertical direction.

[0046] Based on the above embodiments, in an optional embodiment, as shown in Figures 3-6, the concealed mounting bracket 4 includes two parts: a connecting bracket 42 located below the concealed mounting bracket 4 and a top bracket 41 located above the connecting bracket 42. The connecting bracket 42 is a welded inverted "L"-shaped structure. The bottom end of the connecting bracket 42 is a vertical section 421, which is fixedly connected to the mounting bracket connecting seat 43. The end of the connecting bracket 42 away from the mounting bracket connecting seat 43 extends into the top air duct 5, and its top end is provided with a horizontal platform surface 422. The top bracket 41 is located inside the top air duct 5. The top bracket 41 is an upright "L"-shaped structure, and its bottom end is provided with a horizontal base 412. The horizontal base 412 is fixedly connected above the connecting bracket 42. The end of the top bracket 41 away from the connecting bracket 42 passes through the top air duct 5 and is fixedly connected to the vehicle frame (not shown in the figure), so that the concealed mounting bracket 4 is directly connected to the vehicle frame. As shown in Figure 3, the top bracket 41 has a certain angle to facilitate connection with the vehicle frame. In other embodiments, the top bracket 41 is not provided, and the hidden fixing bracket 4 only includes the connecting bracket 42. The top end of the connecting bracket 42 is directly fixedly connected to the vehicle frame, realizing the fixed connection between the rear bumper 1 and the vehicle frame. The end of the connecting bracket 42 that extends upward into the top air duct 5 can be called the connecting top end, and the end of the top bracket 41 that passes through the top air duct 5 and is fixedly connected to the vehicle frame can be called the bracket fixing end.

[0047] The beneficial effects of this application are as follows: the concealed mounting bracket passes through the top air duct, which is equivalent to utilizing the internal space of the top air duct and no longer occupies the external space, thus saving space; on the other hand, since the heightened top is close to the lower side of the top air duct, and the connection position between the concealed mounting bracket and the concealed mounting bracket is covered by the concealing decorative cover, the concealed mounting bracket can be almost completely hidden, so that the concealed mounting bracket is no longer exposed outside the top air duct and avoids obstructing the view.

[0048] Another embodiment of this application provides a driver rear bumper. In this embodiment, the specific structure of the driver rear bumper is the same as that of the driver rear bumper in the above-mentioned bus embodiment, and can achieve the same or corresponding technical effects, which will not be repeated here.

[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. The scope of patent protection of this application shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this application shall also be included within the scope of protection of this application.
