Description

Technical Field

[0001] This utility model relates to the field of interior panel disassembly technology for new energy vehicles, specifically a disassembly tooling for repairing decorative accessories of new energy vehicles. Background Technology

[0002] During the repair and maintenance of new energy vehicles, it is often necessary to disassemble interior panels, trim strips, and other decorative accessories. To avoid scratching or damaging the surfaces of these delicate accessories during disassembly, repair personnel typically use plastic pry bars as disassembly tools.

[0003] However, existing plastic rocker arms have significant shortcomings in practical use: First, because they are made entirely of plastic, their structural strength is limited. When prying some tightly installed or extremely stubborn parts, the plastic rocker arm is prone to bending or even breaking due to excessive force, affecting normal use and posing safety hazards. Second, when encountering parts that require considerable force to pry open, the limited length and short lever arm of the plastic rocker arm often require the operator to apply a lot of force. This not only makes the operation laborious but also further increases the risk of rocker arm breakage. It may also cause accidental damage to the parts or their connecting clips due to excessive force.

[0004] Therefore, we propose a disassembly tool for repairing decorative parts of new energy vehicles. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a disassembly tool for repairing decorative accessories of new energy vehicles. By embedding a retractable metal reinforcing lever inside a plastic rocker and setting a locking structure, the tool's strength is effectively enhanced, labor-saving operation is achieved, and the stability of the working state is ensured, which can effectively solve the problems in the background technology.

[0006] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: a disassembly fixture for repairing decorative accessories of new energy vehicles, including a plastic rocker arm, one end of which is provided with a working end, and a rectangular frame reinforcing rod is embedded and fixedly installed inside the plastic rocker arm. The outer surface of the front end of the rectangular frame reinforcing rod extends to the outer surface of the end of the plastic rocker arm away from the working end. An extension lever is provided in the rectangular frame reinforcing rod, and a handle is fixedly installed on the outer surface of the front end of the extension lever. A locking and limiting structure is provided at the rear end of the upper outer surface of the extension lever. The locking and limiting structure includes an installation cavity, a helical spring, a limiting block, a guide hole, and a locking pin. The front end of the rectangular frame reinforcing rod is open. A pull-out locking hole is opened at the front end of the upper outer surface of the plastic rocker arm, and a receiving locking hole is opened at the rear end of the upper outer surface of the plastic rocker arm.

[0007] Preferably, the extended lever is slidably connected inside the rectangular frame reinforcing rod, and the cross-sectional shape of the extended lever is adapted to the cross-sectional shape of the inner cavity of the rectangular frame reinforcing rod.

[0008] Preferably, both the rectangular frame reinforcing rod and the extended lever are made of metal material, which is high-strength alloy steel or aluminum alloy.

[0009] Preferably, the guide hole is located at the rear end of the outer surface of the upper end of the extended lever, the mounting cavity is located inside the rear end of the extended lever, and the lower end of the guide hole is connected to the middle of the upper end of the mounting cavity. The locking pin passes through the guide hole, and the outer wall of the locking pin is slidably connected to the guide hole.

[0011] Preferably, when the extended lever is fully retracted inside the rectangular frame reinforcing rod, the upper end of the locking pin is engaged in the retraction locking hole under the elastic force of the helical spring; when the extended lever is pulled out from the rectangular frame reinforcing rod to its maximum stroke, the upper end of the locking pin is engaged in the extraction locking hole under the elastic force of the helical spring.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a disassembly tooling for repairing decorative accessories of new energy vehicles, which has the following beneficial effects: 1. This disassembly tool for repairing decorative accessories of new energy vehicles features a rectangular metal reinforcing rod embedded in a hollow plastic rocker. This rod not only serves as a storage channel for the extended lever but, more importantly, as a built-in reinforcing frame, enhancing the structural strength and bending resistance of the plastic rocker. This fundamentally improves the problem of traditional pure plastic rockers easily bending or breaking under excessive force, thus increasing the tool's service life and operational safety.

[0013] 2. This disassembly tool for repairing decorative accessories of new energy vehicles features an extended lever, allowing users to flexibly select the working mode according to the difficulty of the disassembly task. Under normal circumstances, a standard-length pry bar can be used for operation. When encountering extremely stubborn decorative accessories, the extended lever can be pulled out from the rectangular frame reinforcing rod, effectively increasing the lever arm length and thus obtaining a greater torque with the same force, achieving labor-saving operation. This not only reduces the physical requirements of the operator but also avoids accidental damage to accessories or tools due to excessive force.

[0014] 3. This new energy vehicle decorative parts repair disassembly tool has an extended lever that can be completely stored inside the rectangular frame reinforcing rod, so that the tool can maintain a compact shape when not in use or in situations where space is limited, making it easy to carry and store in a toolbox.

[0015] 4. This disassembly tool for repairing decorative accessories of new energy vehicles, through the set locking and limiting structure (composed of mounting cavity, helical spring, limiting block, guide hole and locking pin), can reliably lock the extension lever in two working states of "fully retracted" and "fully extended". It can be unlocked with one press, and the operation is simple and intuitive. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a disassembly tool for repairing decorative accessories of new energy vehicles.

[0023] Specifically, the device includes a plastic rocker arm 1, one end of which has a working end 2 for inserting and prying decorative accessories. Inside the plastic rocker arm 1, a rectangular frame reinforcing rod 5 is embedded and fixedly installed. The front end of the rectangular frame reinforcing rod 5 (the end away from the working end 2) is open, and its outer surface extends to the outer surface of the end of the plastic rocker arm 1 away from the working end 2. On the upper outer surface of the plastic rocker arm 1, a pull-out locking hole 4 is opened at its front end, and a receiving locking hole 3 is opened at its rear end.

[0024] An extended lever 6, serving as an extended lever arm, is disposed inside the rectangular frame reinforcing rod 5. The extended lever 6 is slidably connected to the inside of the rectangular frame reinforcing rod 5, and the cross-sectional shape of the extended lever 6 is adapted to the cross-sectional shape of the inner cavity of the rectangular frame reinforcing rod 5 to ensure that the extended lever 6 can slide stably without wobbling. To enhance the structural strength of the entire fixture, both the rectangular frame reinforcing rod 5 and the extended lever 6 are made of metal materials, preferably high-strength alloy steel or aluminum alloy. A handle 13 is fixedly installed on the outer surface of the front end of the extended lever 6 (i.e., the end extending out of the plastic rocker 1) for easy pulling and gripping by the operator.

[0025] A locking and limiting structure 7 is provided at the rear end of the upper outer surface of the extended lever 6 to stably lock the extended lever 6 in a retracted or withdrawn state. The locking and limiting structure 7 includes a mounting cavity 8, a coil spring 9, a limiting block 10, a guide hole 11, and a locking pin 12. The guide hole 11 is located at the rear end of the upper outer surface of the extended lever 6. The mounting cavity 8 is located inside the rear end of the extended lever 6, and the lower end of the guide hole 11 communicates with the middle of the upper end of the mounting cavity 8. The locking pin 12 passes through the guide hole 11, and the outer wall of the locking pin 12 is slidably connected to the guide hole 11, allowing the locking pin 12 to slide up and down along the guide hole 11. The coil spring 9 and the limiting block 10 are located in the mounting cavity 8. The coil spring 9 is fixed between the lower outer surface of the limiting block 10 and the bottom of the mounting cavity 8. The lower end of the locking pin 12 is fixed to the middle of the upper outer surface of the limiting block 10. Therefore, the lower outer surface of the limiting block 10 is elastically connected to the bottom of the mounting cavity 8 via a helical spring 9.

[0026] The working principle and usage process of this utility model are as follows: Under normal conditions, such as Figure 1 As shown, the extended lever 6 is completely retracted inside the rectangular frame reinforcing rod 5. At this time, the upper end of the locking pin 12 in the locking and limiting structure 7, under the elastic force of the coil spring 9, pops upward and engages with the storage locking hole 3 on the plastic rocker 1. This state reliably locks the extended lever 6 in the retracted position, making the overall structure of the tooling compact, easy to carry and store, and usable as a standard plastic rocker. Its built-in rectangular frame reinforcing rod 5 enhances the bending strength of the plastic rocker 1 body.

[0027] When it is necessary to disassemble tightly installed or extremely stubborn decorative accessories, the operator needs to pull out the extension lever 6 to obtain a longer lever arm for easier operation. The operation is as follows: Press the upper end of the locking pin 12 currently stuck in the storage locking hole 3. The pressing force is transmitted through the locking pin 12 to the limiting block 10, which moves downward against the elastic force of the coil spring 9 until the upper end of the locking pin 12 is completely out of the storage locking hole 3, thus unlocking. While holding the pressing position, pull the handle 13 to pull the extension lever 6 forward (i.e., in the opposite direction to the working end 2) from the rectangular frame reinforcing rod 5.

[0028] When the extended lever 6 is pulled out to its maximum length, that is, when its tail end is close to the open front end of the rectangular frame reinforcing rod 5, as Figure 2 As shown, the locking pin 12 springs upward under the restoring force of the coil spring 9, and its upper part engages with the pull-out locking hole 4 at the front end of the plastic rocker 1. This state reliably locks the extended lever 6 in the fully extended position. At this time, due to the extended lever arm, the operator can apply a smaller force to the handle 13 to generate a larger torque at the working end 2, easily prying up stubborn decorative accessories, saving effort and reducing the risk of damage to tools and accessories.

[0029] When it is necessary to retract the extension lever 6, repeat the above unlocking action: press the locking pin 12 to make it exit the pull-out locking hole 4, and then push the extension lever 6 back into the rectangular frame reinforcing rod 5 until the locking pin 12 is locked back into the storage locking hole 3.
