Description

Technical Field

[0001] This invention belongs to the field of automotive interior parts technology, and more specifically, it relates to a universal mounting assembly for trunk lids of diesel and hybrid vehicles. Background Technology

[0002] With the development of automotive technology, hybrid vehicles have become the mainstream choice in the transition to new energy vehicles. Compared with diesel models on the same platform, hybrid models have different spare tire compartment depth, chassis ground clearance, and tool tray installation position and height due to the addition of components such as battery packs and electronic control systems. In the current technology, the trunk lids of diesel and hybrid models on the same platform usually adopt a customized solution, that is, the lids and matching installation components with different shapes, sizes, and installation structures are designed for the two models respectively.

[0003] Chinese patent document CN222933969U discloses a limiting structure for a trunk lid and a vehicle, which includes a fixing plate disposed at the front end of a tool tray and a limiting member disposed on the trunk lid accordingly; the limiting member has a limiting arm extending downward toward the trunk lid, and the end of the limiting arm is formed with a hook portion protruding toward the front side of the vehicle; the hook portion is hooked onto the fixing plate, thereby restricting the trunk lid from moving upward relative to the tool tray; the limiting member is directly screwed to the trunk lid by fasteners.

[0004] While the above structure can limit the up-and-down swaying of the cover and reduce abnormal noise through hook-and-loop connection, it has the following drawbacks: 1. The limiting component is directly fixed to the cover body, and the limiting function is integrated with the cover body, making it impossible to replace and adapt to the side limiting anchor point structure of different vehicle models. When the spare tire compartment is raised due to the addition of the battery pack in hybrid models, or when the position and form of the side limiting anchor points change, the cover cannot be adapted, which can easily lead to uneven gaps, swaying, and abnormal noise. 2. Different cover plates and installation components need to be developed for diesel and hybrid models on the same platform, resulting in high mold development costs, long R&D cycles, and the parts of the two types of cover plates are not interchangeable, increasing production and inventory management costs. 3. The fixing plate of this solution is set on the upper surface of the front end of the tool tray, which can only be adapted to models equipped with a tool tray. For hybrid models and other models without a tool tray, where the battery pack bracket is the main side structure of the vehicle body, this limiting structure is completely unusable, resulting in poor versatility. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a universal mounting component for trunk lids of diesel and hybrid vehicles, so as to achieve stable adaptation of the same trunk lid to the body of diesel and hybrid vehicles, without the need for separate customization of the lid, thereby reducing development costs and improving assembly efficiency and usage stability.

[0006] The universal mounting assembly for trunk lids of diesel and hybrid vehicles includes a lid body; Universal mounting bracket, which is fixedly connected to the cover plate body; The limiting component is detachably fixed to a universal mounting bracket and includes interchangeable limiting hooks and limiting bases. The limit hook is used to engage with the fixing seat in the tool box of the trunk of the diesel version to limit the shaking of the cover body; The limiting base is used to engage with the opening in the battery pack bracket of the hybrid model to limit the shaking of the cover body.

[0007] Preferably, the installation positions of the limiting hook and the limiting base on the universal mounting bracket coincide.

[0008] Preferably, the limiting hook and the universal mounting bracket, and the limiting base and the universal mounting bracket are respectively detachably fixedly connected by the same fasteners.

[0009] Preferably, the fastener is a cross-head self-tapping screw with a large semi-circular head.

[0010] Preferably, the universal mounting bracket and the cover plate body are fixed together by a four-prong nut and a rounded flange bolt, and a flat washer is fitted on the rounded flange bolt.

[0011] Preferably, the trunk toolbox includes a toolbox body and a fixing base, the fixing base being embedded inside the toolbox body, and the fixing base having a slot that cooperates with the limiting hook.

[0012] Preferably, the limiting hook is engaged with the fixed seat to limit the swaying of the cover plate body in the vertical direction.

[0013] Preferably, the limiting base is inserted into the opening of the battery pack bracket to limit the swaying of the cover body in the horizontal and / or vertical directions.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention sets a universal mounting bracket on the cover plate body and designs the limiting component as an independent part that can be detachably fixed on the universal mounting bracket, thereby decoupling the limiting function from the cover plate body. This achieves a modular design of "universal body + interchangeable limiting component", that is, the same cover plate body and universal mounting bracket can be used on diesel and hybrid models. Only the limiting component needs to be replaced to adapt to different models. There is no need to develop two sets of cover plate molds separately, which reduces the mold development cost.

[0015] 2. The limiting components are interchangeable limiting hooks and limiting bases. The two are installed in the same position on the universal mounting bracket and are fixedly connected by the same fasteners. By replacing the limiting hooks or limiting bases, the same cover plate assembly can be adapted to diesel and hybrid models respectively, reducing the types of parts, reducing production and inventory management costs, facilitating interchangeability, and improving assembly efficiency.

[0016] 3. This invention employs a limiting hook suitable for diesel vehicles, which restricts the cover's vertical movement by hooking onto a pre-embedded fixing seat in the trunk tool box. A limiting base suitable for hybrid vehicles restricts the cover's horizontal and / or vertical movement by inserting into an opening in the battery pack bracket. Both limiting methods utilize the existing structures of the two vehicle models as limiting anchor points, requiring no modification to any side structure of the vehicle body. This highly practical approach effectively eliminates cover wobbling and noise.

[0017] 4. The universal mounting bracket and the cover plate body are fixed by bolts with four-prong nuts and rounded flange bolts. Flat washers are fitted on the bolts, which ensures high connection strength, uniform force distribution, and good anti-loosening performance. The limiting component is fixed to the universal mounting bracket by cross-slot semi-circular head self-tapping screws, which are easy to install, disassemble and replace, and facilitate after-sales maintenance.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings: The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise explicitly specified and limited, the terms "setting," "installing," "connecting," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] Example 1: This example applies to diesel models.

[0022] like Figure 1 As shown, a universal mounting assembly for a trunk lid suitable for diesel vehicles includes a trunk lid assembly 1, which, when applied, engages with a trunk tool box 2 and a trunk side panel assembly 3.

[0023] like Figure 2 As shown, the luggage compartment cover assembly 1 includes a cover body 101, a universal mounting bracket 102, and a limiting hook 103. The universal mounting bracket 102 is installed at the bottom of the cover body 101. The cover body 101 and the universal mounting bracket 102 are fixed together by multiple sets of four-prong nuts 105 and rounded flange bolts 106, and flat washers are fitted on the rounded flange bolts 106. The screw points are distributed along the contour of the universal mounting bracket 102 to ensure connection strength and uniform force distribution. In this embodiment, there are 11 screw points, which are located on both sides near the width direction of the universal mounting bracket 102. The screw points on opposite sides are staggered, and the screw points on the same side are evenly spaced.

[0024] like Figure 10 and Figure 11As shown, during installation, the four-prong nut 105 is pre-embedded in the cover plate body 101, and the rounded flange bolt 106 passes through the mounting hole on the universal mounting bracket 102 and is screwed to the four-prong nut 105, thereby achieving rigid fixation between the universal mounting bracket 102 and the cover plate body 101. A flat washer is fitted onto the rounded flange bolt 106, located between the bolt head and the universal mounting bracket 102, which increases the contact area, prevents loosening, and protects the mounting surface.

[0025] like Figure 3 As shown, the limiting hook 103 is detachably fixed to the universal mounting bracket 102 via a fastener 107. The limiting hook 103 has a screw through-hole corresponding to the mounting position on the universal mounting bracket 102. The fastener 107 passes through this through-hole and is screwed into a pre-set screw hole in the universal mounting bracket 102, thus achieving detachable fixing of the limiting hook 103. In this embodiment, the fastener 107 is a Phillips head self-tapping screw with a large semi-circular head.

[0026] like Figures 4 to 6 As shown, the trunk toolbox 2 includes a toolbox body 201 and a mounting base 202. The mounting base 202 is embedded inside the toolbox body 201, and the mounting base 202 is provided with a slot 203 that cooperates with the limiting hook 103. In this embodiment, the hook of the limiting hook 103 hooks into the slot 203 of the mounting base 202, so that the limiting hook 103 and the mounting base 202 are engaged to limit the shaking of the cover body 101 in the vertical direction, thereby eliminating the abnormal noise caused by the up-and-down shaking of the cover during vehicle operation.

[0027] Example 2: This example applies to hybrid models.

[0028] like Figure 7 As shown, a universal mounting assembly for a trunk lid suitable for hybrid vehicles includes a trunk lid assembly 1, a trunk side panel assembly 3, a battery pack bracket 4, and a power battery pack assembly 5.

[0029] like Figure 8 As shown, the luggage compartment cover assembly 1 includes a cover body 101, a universal mounting bracket 102, and a limiting base 104. The limiting base 104 and the universal mounting bracket 102 are also detachably fixedly connected by fasteners 107. The fasteners 107 are also Phillips head self-tapping screws with large semi-circular heads.

[0030] like Figure 9 As shown, the limiting base 104 is inserted into the opening of the battery pack bracket 4. The limiting base 104 is inserted into the opening of the battery pack bracket 4. Through the cooperation between the limiting base 104 and the opening of the battery pack bracket 4, the swaying of the cover body 101 in the horizontal direction, the vertical direction, or both directions simultaneously is restricted, thereby eliminating abnormal noise caused by the swaying of the cover during vehicle operation. Other aspects are the same as in Embodiment 1.

[0031] Example 3: like Figure 3 As shown, the screw through holes on the limiting base 104 and the screw through holes on the limiting hook 103 have the same position and specifications, and both are fixedly connected to the universal mounting bracket 102 by fasteners 107 of the same specifications. Therefore, the mounting positions of the limiting base 104 and the limiting hook 103 on the universal mounting bracket 102 coincide, and they can be interchangeably installed in the same mounting position on the universal mounting bracket 102 to match the counterpart parts of different power vehicles.

[0032] When used on diesel vehicles, the limit hook 103 is mounted on the universal mounting bracket 102; when used on hybrid vehicles, the limit base 104 is mounted on the universal mounting bracket 102. The two are interchangeable and easy to install, eliminating the need for a separate cover plate, reducing development costs and improving assembly efficiency.

[0033] Working principle: First, place the universal mounting bracket 102 at the corresponding position below the cover body 101, aligning the mounting holes on the universal mounting bracket 102 with the four-pronged nuts 105 pre-embedded in the cover body 101. Then, put the flat washer on the rounded flange bolt 106 and use the rounded flange bolt 106 to screw and fix the universal mounting bracket 102 to the cover body 101, forming the universal main body of the luggage compartment cover assembly.

[0034] Then, select the corresponding limiting component according to the vehicle model: for diesel models, place the limiting hook 103 in the corresponding installation position of the universal mounting bracket 102 and fix it with fastener 107 (cross-slot large semi-circular head self-tapping screw); for hybrid models, place the limiting base 104 in the same installation position of the universal mounting bracket 102 and fix it with the same fastener 107.

[0035] Finally, the assembled trunk lid assembly is installed into the vehicle's trunk: in the diesel version, the limiting hook 103 hooks into the slot of the pre-embedded fixing seat 202 inside the trunk tool box 2; in the hybrid version, the limiting base 104 is inserted into the opening of the battery pack bracket 4 to complete the installation.

[0036] When switching the same cover assembly from a diesel model to a hybrid model, simply unscrew the fastener 107 securing the limiting hook 103, remove the limiting hook 103, replace it with the limiting base 104, and re-secure it in the same mounting position using the same fastener 107. There is no need to replace the cover body 101 and the universal mounting bracket 102; the interchangeability is convenient. Conversely, the operation is the same when switching from a hybrid to a diesel version.

[0037] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
