Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a battery lower guard plate assembly that is easy to install and remove. Background Technology

[0002] In today's new energy vehicle industry, the battery, as one of the core components, is of paramount importance in terms of safety and stability. The battery underbody protection assembly, as a key component protecting the battery, plays a crucial role in preventing damage from road debris, mud, water erosion, and other external factors.

[0003] Figure 1 The common method for installing a lower guard plate in the prior art is to install a T-bolt (300) in a rectangular hole (200) on the frame (100) through a washer (400) and a first nut (500) to fix the T-bolt (300). Then, the guard plate body (1) is installed on the T-bolt (300) through a second nut (600).

[0004] However, the above installation method is rather cumbersome. It requires the use of professional tools for installation and removal, and a large number of connectors need to be disassembled or installed one by one, which consumes a lot of time and manpower and results in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a battery lower guard plate assembly that is easy to install and remove, effectively solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A battery lower guard plate assembly that is easy to install and remove includes a guard plate body. Multiple through holes are formed on the surface of the guard plate body. Guide rods are installed inside the through holes, and hooks are provided on both sides of the bottom of the guide rods. A torsion bar is installed on the top of the guide rods. An annular plate is installed on the upper surface of the guard plate body, outside the through holes. Insertion holes are formed on the inner wall of the annular plate, and an insertion mechanism that engages with the insertion holes is provided inside the torsion bar.

[0008] As can be seen, by passing the guide rod through the rectangular hole on the frame, rotating the torsion bar to cause the hook block to be misaligned with the rectangular hole, and using the insertion mechanism to fit into the insertion hole to limit the angle of the guide rod, the guard plate body can be fixedly installed. This not only improves the efficiency of loading and unloading, but also eliminates the need for professional tools, reducing time and labor costs and significantly improving work efficiency.

[0009] Furthermore, the insertion mechanism includes a mounting hole inside the torsion bar, a insertion rod disposed inside the mounting hole, a groove formed on the inner wall of the mounting hole, and a shoulder formed on the outer surface of the insertion rod, the shoulder being disposed within the groove. A spring is fitted onto the outer surface of the insertion rod, with both ends of the spring abutting against the shoulder and the inner wall of the groove, respectively.

[0010] Furthermore, a groove is provided on the surface of the torsion bar, and a lever is provided inside the groove, with the insertion rod connected to the outer surface of the lever.

[0011] Furthermore, a rubber pad is provided on the lower surface of the protective plate body at the through hole.

[0012] Furthermore, two arc-shaped plates are symmetrically arranged on the upper surface of the guard plate body, located inside the annular plate, with beveled portions at both ends of the arc-shaped plates. Arc-shaped portions are also provided on both sides of the bottom of the torsion bar.

[0013] Furthermore, the side of the insert facing the inner wall of the annular plate has a spherical structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model achieves the fixed installation of the guard plate body by passing the guide rod through the rectangular hole on the frame, rotating the torsion bar to drive the hook block to be misaligned with the rectangular hole, and using the plug-in mechanism to fit the plug hole to limit the angle of the guide rod. This not only improves the efficiency of loading and unloading, but also eliminates the need for professional tools, reducing time and labor costs and significantly improving work efficiency.

[0016] 2. By setting up the arc-shaped plate, the inclined surface and the arc-shaped part, the height of the torsion bar can be raised when it is rotated, thereby driving the hook block to hook tightly onto the upper side of the frame, improving the tightness of the installation of the guard plate body. In addition, with the setting of the rubber pad, it can also play a shock absorption role, reducing the impact of vehicle vibration on the guard plate body and avoiding the generation of noise.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1-6 This utility model provides a battery lower guard plate assembly that is easy to install and remove, including a guard plate body 1. The surface of the guard plate body 1 has multiple through holes 101. A guide rod 102 is disposed inside each through hole 101. Hooks 103 are disposed on both sides of the bottom of the guide rod 102. A torsion rod 104 is mounted on the top of the guide rod 102. An annular plate 105 is mounted on the upper surface of the guard plate body 1, outside the through holes 101. An insertion hole 106 is formed on the inner wall of the annular plate 105. An insertion mechanism 2 is disposed inside the torsion rod 104 to engage with the insertion hole 106.

[0026] When installing the protective plate body 1, the worker inserts the guide rod 102 into the rectangular hole 200 on the frame 100, so that the hook block 103 is positioned above the frame 100. Then, the torsion bar 104 is rotated to cause the hook block 103 to be misaligned with the rectangular hole 200. Through the insertion mechanism 2 and the insertion hole 106, the torsion bar 104 can be fixed, preventing the hook block 103 from being pulled out of the rectangular hole 200, thus completing the installation of the protective plate body 1. When disassembling the protective plate body 1, it is only necessary to release the insertion mechanism 2 from the insertion hole 106, and then rotate the torsion bar 104 to make the hook block 103 correspond to the rectangular hole 200, so that it can be pulled out of the rectangular hole 200. This not only improves the efficiency of installation and removal, but also eliminates the need for professional tools, reducing time and labor costs and significantly improving work efficiency.

[0027] Preferably, the insertion mechanism 2 includes a mounting hole 201 inside the torsion bar 104, an insertion rod 202 is disposed inside the mounting hole 201, a groove 203 is formed on the inner wall of the mounting hole 201, and a shoulder 204 is provided on the outer surface of the insertion rod 202, which is disposed within the groove 203. A spring 205 is sleeved on the outer surface of the insertion rod 202, and the two ends of the spring 205 abut against the shoulder 204 and the inner wall of the groove 203, respectively.

[0028] Spring 205 applies a pushing force to shoulder 204, thereby causing the end of insertion rod 202 to abut against the inner wall of annular plate 105. When torsion bar 104 is rotated, the end of insertion rod 202 slides on the inner wall of annular plate 105. When the end of insertion rod 202 is aligned with insertion hole 106, under the elastic force of spring 205, insertion rod 202 can be pushed to automatically insert into insertion hole 106, thus completing the fixation of torsion bar 104.

[0029] Preferably, the surface of the torsion bar 104 is provided with a groove 3, the inside of the groove 3 is provided with a lever 301, and the insertion rod 202 is connected to the outer surface of the lever 301.

[0030] When the lever 301 slides in the groove 3, it can move the insert rod 202 and pull it out of the insertion hole 106, thereby releasing the fixation of the torsion rod 104 and facilitating the removal of the guard plate body 1.

[0031] Preferably, a rubber pad 4 is provided on the lower surface of the protective plate body 1 at the through hole 101.

[0032] The rubber pad 4 not only improves the stability of the guard plate body 1 installation, but also plays a role in shock absorption, reducing the impact of vehicle vibration on the guard plate body 1 and avoiding noise generation.

[0033] Preferably, two arc-shaped plates 5 are symmetrically arranged on the upper surface of the guard plate body 1 and inside the annular plate 105, and both ends of the arc-shaped plates 5 are provided with inclined portions 501. Arc-shaped portions 502 are provided on both sides of the bottom of the torsion bar 104.

[0034] When the torsion bar 104 is rotated, the bottom of the torsion bar 104 slides along the surface of the inclined surface 501, thereby raising its height and causing the hook block 103 to hook tightly onto the upper side of the frame 100, improving the tightness of the installation of the guard plate body 1.

[0035] Preferably, the side of the insertion rod 202 facing the inner wall of the annular plate 105 has a spherical structure.

[0036] The spherical structure design reduces the friction between the end of the insertion rod 202 and the inner wall of the annular plate 105, making it easier to rotate the torsion bar 104 to install the guard plate body 1.
