Abstract
Description
Technical Field
[0001] This utility model relates to a concealed lock structure for the rear engine compartment door of a bus, specifically an unlocking and opening structure applicable to the rear engine compartment door of various motor vehicles such as buses and commercial vehicles. Background Technology
[0002] Currently, the rear engine compartment door of buses typically uses the same handle lock as the side luggage compartment door or a simple lock used for maintenance doors. A small number of vehicles use impact-type locks without exposed structures. The above door lock arrangements can meet basic functional requirements, but they are less aesthetically pleasing and less comfortable.
[0003] When using a handle lock structure, in order to ensure balanced force distribution, the handle is usually placed in the middle of the hatch, near the rear license plate installation position. To ensure convenient operation and easy gripping, the handle size is usually relatively large. This makes it difficult for the handle placement to blend with the overall style of the rear panel, resulting in poor aesthetics.
[0004] When using simple locks, two simple locks need to be placed on both sides of the hatch. The simple locks are small in size and have little impact on the overall appearance of the rear enclosure. However, locking and unlocking require two separate operations, which is cumbersome and inconvenient to use. In addition, since there is no handle function, the lower edge of the hatch needs to be gripped when operating, resulting in a poor feel. The bumper lock without an exposed handle does not affect the appearance of the rear enclosure. However, it usually has no anti-theft function, and in order to ensure that the hatch closes reliably and does not accidentally swing open, the locking force is usually large. When opening the hatch, a lot of force is required to pull the lower edge of the hatch to overcome the locking force and open the hatch. When closing the hatch, a lot of force is required to ensure that the bumper lock is engaged. The above operations have a poor feel, are noisy, and have a low quality feel. Utility Model Content
[0005] The purpose of this utility model is to provide a concealed handle lock structure that is highly integrated with features such as the rear door, rear license plate light, and license plate recess.
[0006] To solve the above problems, this utility model is achieved through the following technical solution:
[0007] A concealed lock structure for a bus rear engine compartment door includes a rear engine compartment door, a license plate light decorative piece is provided on the rear engine compartment door, and a license plate light and a handle lock are provided on the license plate light decorative piece.
[0008] The license plate light decorative component includes an upper arc-shaped component and a bottom support plate. One end of the bottom support plate is fixed to the rear engine compartment door, and the other end of the bottom support plate is connected to one end of the upper arc-shaped component. The other end of the upper arc-shaped component is fixed to the rear engine compartment door. A handle lock and a license plate light are provided on the bottom support plate.
[0009] The handle lock is installed on the door lock bracket with fixing bolts, and the door lock bracket is fixedly connected to the rear engine compartment door.
[0010] The handle lock includes a handle groove and a lock cylinder.
[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a handle lock arrangement scheme that integrates a lock cylinder structure and hides it in the license plate light decorative piece. The handle lock with integrated lock cylinder is hidden, and at the same time, the license plate decorative piece integrates a license plate light. The shape of the license plate decorative piece echoes the overall shape of the license plate recess and the rear enclosure, which effectively improves the overall aesthetics. Attached Figure Description
[0012] Figure 1 This is a schematic diagram of the overall structure of this utility model;
[0013] Figure 2 A structural diagram showing the arrangement of the concealed handle lock for the rear engine compartment door;
[0014] Figure 3 This is a rendering of the present invention. Detailed Implementation
[0015] 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.
[0016] 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.
[0017] like Figure 1 , Figure 2 and Figure 3 As shown, a concealed lock structure for the rear engine compartment door of a bus includes a rear engine compartment door 1, a license plate light decorative piece 2 on the rear engine compartment door 1, a license plate light 3 and a handle lock 4 on the license plate light decorative piece 2.
[0018] The license plate light decorative piece 2 includes an upper arc-shaped piece 21 and a bottom support plate 22. One end of the bottom support plate 22 is fixed to the rear engine compartment door 1, and the other end of the bottom support plate 22 is connected to one end of the upper arc-shaped piece 21. The other end of the upper arc-shaped piece 21 is fixed to the rear engine compartment door 1. In other words, the license plate light decorative piece 2 protrudes from the rear engine compartment door 1. A handle lock 4 and a license plate light 3 are provided on the bottom support plate 22.
[0019] During assembly, the handle lock 4 is installed on the door lock bracket 6 by fixing bolts 5, and the door lock bracket 6 is fixedly connected to the rear engine compartment door 1.
[0020] Furthermore, the handle lock 4 includes a handle groove 41 and a lock cylinder 42, that is, the lock cylinder 42 is integrated into the handle lock 4.
[0021] The working principle of this utility model is as follows:
[0022] This utility model assembles the license plate light decorative piece 2 and the license plate light 3 together into a single component. The handle lock 4 is fitted inside this component, which covers the handle lock 4, exposing only the operating handle groove 41 and the lock cylinder 42 for key unlocking. This arrangement satisfies anti-theft, door opening / closing functions, and operational comfort. Furthermore, by concealing the functional components, this arrangement significantly enhances the aesthetics and structural refinement of the rear enclosure.
[0023] Conventional engine compartment door lock designs primarily prioritize basic functionality, with less consideration for aesthetics, ease of operation, and noise levels, resulting in a generally poor product quality. This utility model integrates a lock cylinder with the handle lock 4 concealed within the license plate light trim. While providing operational comfort and anti-theft functionality, it integrates the license plate light structure into the trim while hiding the door lock. The license plate trim's shape can be freely designed to complement the license plate recess and the overall rear panel design, enhancing the product's premium feel and meeting the demands of high-end vehicles.
[0024] 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.
