Description

Technical Field

[0001] This utility model relates to the field of automotive swing arm technology, specifically a lightweight new energy vehicle swing arm. Background Technology

[0002] As a key guiding and load-bearing component of the suspension system, the lower control arm must withstand the combined loads generated during acceleration, braking, and steering during vehicle operation. Its mechanical properties directly affect the vehicle's handling stability and driving safety, making it one of the core components determining the dynamic characteristics of the chassis system. Innovative lower control arm products developed to meet the lightweight requirements of new energy vehicles effectively improve the energy efficiency and driving range of electric vehicles by using advanced lightweight materials such as high-strength aluminum alloys or composite materials. However, existing lower control arms, once damaged by impacts and cracks appear, will affect the structural strength and support. If the damage to the lower control arm is not detected in time, safety hazards may arise during subsequent vehicle operation.

[0003] For example, the prior art represented by the lightweight lower control arm for new energy vehicles (publication number CN 217532440U) in the prior art patent technology, through the setting of a replacement piece, allows the replacement piece to be directly removed when repairing the lower control arm, which reduces the cost of replacing the lower control arm to a certain extent. It is very practical and effectively solves the problems of the prior art. However, its structure still needs to be improved, as follows:

[0004] In this design, limiting strips are provided on both the outer side of the lower control arm and the outer side of the replacement plate. The limiting strips can limit the clamping plate, making it easier for the clamping plate to connect and fix the replacement plate to the lower control arm. The replacement plate is provided on the outer side of the lower control arm. However, the lower control arm is easily damaged by bumps during driving. If the lower control arm body is damaged by bumps, the replacement plate on the outer side plays a limited role, and the lower control arm still needs to be repaired and replaced, which leads to high maintenance costs. Therefore, a lightweight new energy vehicle control arm is needed to improve the above problems. Utility Model Content

[0005] To address the issue that when a car's control arm is damaged by impacts during use, the outer replacement plate offers limited protection, necessitating repair and replacement, which leads to high maintenance costs, this invention provides a lightweight control arm for new energy vehicles to solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lightweight new energy vehicle swing arm includes a lower swing arm bracket. A fixed base is inserted and installed on the outer wall of the lower swing arm bracket. The outer wall of the fixed base has an installation hole. A bolt connector is rotatably connected to the inner wall of the installation hole. One end of the bolt connector is threaded to the lower swing arm bracket for fixation. A fixed sleeve is installed on the outer wall of the fixed base. A connecting scale sleeve is inserted and installed on the inner wall of the fixed sleeve.

[0008] A sealing assembly is installed on the outer wall of the lower swing arm bracket, and a fixing plate is installed at the other end of the lower swing arm bracket. A fixing hole is opened on the outer wall of the fixing plate, and a lower swing arm ball joint connector is installed on the outer wall of the fixing plate by fixing bolts.

[0009] As a preferred embodiment of this utility model, the sealing assembly includes a controller, an upper housing, and a lower housing. The controller is embedded in the outer wall of the lower control arm bracket, and an mounting plate is installed on the side wall of the controller. The upper housing is plugged into the outer wall of the controller, and the mounting plate is located in the inner cavity of the upper housing. A valve core valve is embedded in the outer wall of the controller, and one end of the valve core valve passes through the controller and extends into the inner cavity of the upper housing.

[0010] As a preferred embodiment of this utility model, the lower housing is plugged into and installed at the port of the upper housing, wherein a sealing gasket is provided at the connection between the upper housing and the lower housing, a pressure sensor is installed between the upper housing and the lower housing and on the inner wall of the lower swing arm bracket, and a buzzer is provided on the bottom outer wall of the fixing plate.

[0011] As a preferred embodiment of this utility model, a limiting bolt is rotatably connected to the outer wall of the upper housing. One end of the limiting bolt passes through a fixing hole and is threaded to the inner wall of the lower housing. A fixing screw is installed on the outer wall of the upper housing, wherein one end of the fixing screw passes through a mounting plate and is threaded to the inner wall of the lower housing.

[0012] As a preferred embodiment of this utility model, the controller is electrically connected to a pressure sensor and a buzzer via wires.

[0013] As a preferred embodiment of this utility model, the fixed base is provided in two sets and is located on the outer wall of the lower swing arm bracket, and the mounting holes are provided in two sets and are located on the outer wall of the fixed base.

[0014] As a preferred embodiment of this utility model, the fixing sleeve is provided in two sets and is located on the outer wall of the fixing base respectively, and the fixing hole is provided in multiple sets and is located on the outer wall of the fixing plate respectively.

[0015] As a preferred embodiment of this utility model, the lower swing arm bracket is located in the inner cavity of the upper and lower housings, the sealing gasket is made of rubber, and the air pressure sensor is located in the inner cavity of the upper and lower housings.

[0016] As a preferred embodiment of this utility model, the limiting bolts are provided in multiple sets and are respectively located on the inner wall of the fixing hole. The connection between the limiting bolts and the fixing hole is a rotatable connection, and the connection between the fixing screw and the mounting plate is a rotatable connection.

[0017] Compared with existing technologies, this utility model protects the lower control arm bracket by setting an upper and lower housing in the lightweight new energy vehicle control arm. The upper and lower housings are set on the opposite outer walls of the lower control arm bracket. The lower housing is then fixed to the outer wall of the lower housing by fixing screws and mounting plates, and then fixed to the outer wall of the lower housing by limiting bolts through fixing holes. The upper and lower housings are replaceable parts, and they protect the lower control arm bracket in the inner cavity, preventing it from being easily damaged by impacts. This solves the problem that the replacement piece on the outside of the lower control arm body has limited effect when the lower control arm body is damaged by impacts, and still requires the lower control arm to be repaired and replaced, which leads to high maintenance costs.

[0018] This invention enables real-time monitoring of the internal air pressure of the lower control arm bracket, lower housing, and upper housing by incorporating a sealing component in the lightweight new energy vehicle control arm. This allows for alerts when air pressure changes occur. After the upper and lower housings are installed, they are inflated to the set value via a valve core valve. Subsequently, the air pressure sensor generates data based on the air pressure between the upper and lower housings in real time. Simultaneously, the air pressure sensor generates an electrical signal that is transmitted to the controller via wires. When the device is damaged by an impact, the sealing of the upper and lower housings is affected, causing gas to escape from the internal cavity. When the air pressure sensor reading reaches the set parameter, the controller activates a buzzer to produce an audible alert when the driver approaches the vehicle. This addresses the issue of cracks in the lower control arm due to impacts affecting the structural strength and support, and the potential safety hazards that may arise if damage to the lower control arm is not detected in time.

A fixed sleeve 5 is installed on the outer wall of the fixed base 2. A connecting scale sleeve 6 is inserted and installed on the inner wall of the fixed sleeve 5.

[0027] A sealing component 7 is installed on the outer wall of the lower control arm bracket 1, and a fixing plate 8 is installed on the other end of the lower control arm bracket 1. A fixing hole 9 is opened on the outer wall of the fixing plate 8, and a lower control arm ball joint connector 11 is installed on the outer wall of the fixing plate 8 by fixing bolts 10.

[0028] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The sealing assembly 7 includes a controller 701, an upper housing 702, and a lower housing 703. The controller 701 is embedded in the outer wall of the lower control arm bracket 1. A mounting plate 704 is mounted on the side wall of the controller 701. The upper housing 702 is plugged into the outer wall of the controller 701, and the mounting plate 704 is located in the inner cavity of the upper housing 702. A valve core valve 705 is embedded in the outer wall of the controller 701, and one end of the valve core valve 705 passes through the controller 701 and extends into the inner cavity of the upper housing 702. The lower housing 703 is plugged into the port of the upper housing 702. A sealing gasket 706 is provided at the connection between the upper housing 702 and the lower housing 703. A pressure sensor 707 is installed between the upper housing 702 and the lower housing 703 and on the inner wall of the lower swing arm bracket 1. A buzzer 708 is provided on the bottom outer wall of the fixing plate 8. A limit bolt 709 is rotatably connected to the outer wall of the upper housing 702. One end of the limit bolt 709 passes through the fixing hole 9 and is threaded to the inner wall of the lower housing 703. A fixing screw 710 is installed on the outer wall of the upper housing 702. One end of the fixing screw 710 passes through the mounting plate 704 and is threaded to the inner wall of the lower housing 703.

[0029] Based on the above structural features and connection relationships, the overall volume of the lower swing arm bracket 1 is reduced, and triangular reinforcing ribs are provided between the lower swing arm brackets 1, so that the lower swing arm bracket 1 can meet the requirements of support and lightweight.

[0030] The controller 701 is electrically connected to the pressure sensor 707 and the buzzer 708 via wires, which powers the device and enables the controller 701 to control the operation of the pressure sensor 707 and the buzzer 708. Two sets of fixed bases 2 are located on the outer wall of the lower swing arm bracket 1. Two sets of mounting holes 3 are located on the outer wall of the fixed base 2. Two sets of fixed sleeves 5 are located on the outer wall of the fixed base 2. Multiple sets of fixing holes 9 are located on the outer wall of the fixing plate 8. The lower swing arm bracket 1 is located within the cavities of the upper housing 702 and the lower housing 703. The sealing gasket 706 is made of rubber. The pressure sensor 707 is located within the cavities of the upper housing 702 and the lower housing 703. Multiple sets of limit bolts 709 are located on the inner walls of the fixing holes 9. The limit bolts 709 and the fixing holes 9 are connected by a rotating connection. The fixing screws 710 and the mounting plate 704 are also connected by a rotating connection.

[0031] In this lightweight new energy vehicle swing arm design, the controller 701, connected to a pressure sensor 707 and a buzzer 708 via wires, powers the device, causing the controller 701 to control the operation of these two devices. A fixed base 2 is installed on the outer wall of the lower swing arm bracket 1, with mounting holes 3 on its outer wall. A bolt connector 4 rotatably connects to the inner wall of the mounting hole 3, separating the lower swing arm bracket 1 from the connecting scale sleeve 6. To replace the connecting scale sleeve 6, simply loosen the bolt connector 4 to disconnect the fixed base 2 from the lower swing arm bracket 1, allowing the fixed base 2 to be removed for replacement. Simultaneously, the overall volume of the lower swing arm bracket 1 is reduced, and triangular reinforcing ribs are incorporated between the lower swing arm brackets, ensuring both structural support and lightweight design.

[0032] The upper housing 702 is plugged into and installed on the outer wall of the controller 701, and the mounting plate 704 is located in the inner cavity of the upper housing 702. The lower housing 703 is plugged into and installed at the port of the upper housing 702. Under the action of the sealing gasket 706 at the connection between the upper housing 702 and the lower housing 703, the upper housing 702 and the lower housing 703 are set on the opposite outer walls of the lower swing arm bracket 1. Then, the lower housing 702 is fixed to the outer wall of the lower housing 703 by the mounting plate 704 through the fixing screw 710, and then fixed to the outer wall of the lower housing 703 by the fixing hole 9 through the limiting bolt 709. The upper housing 702 and the lower housing 703 are replacement parts, and the upper housing 702 and the lower housing 703 protect the lower swing arm bracket 1 in the inner cavity to prevent the lower swing arm bracket 1 from being easily bumped. This solves the problem that the replacement piece on the outside is limited in its role when the lower swing arm body is damaged by bumps, and the lower swing arm still needs to be repaired and replaced, which will lead to high maintenance costs.

[0033] By embedding a valve core valve 705 on the outer wall of the controller 701, with one end of the valve core valve 705 penetrating the controller 701 and extending into the inner cavity of the upper housing 702, after the upper housing 702 and lower housing 703 are installed, the valve core valve 705 inflates the air to make the air pressure in the inner cavity of the sealing assembly 7 reach a set value. Subsequently, the air pressure sensor 707 generates data in real time based on the air pressure between the upper housing 702 and lower housing 703, and at the same time, the air pressure sensor 707 generates an electrical signal that is transmitted to the controller 701 through a wire. When the device is damaged by an impact, the sealing of the upper housing 702 and the lower housing 703 is affected, causing gas to escape from its internal cavity. At the same time, when the value generated by the air pressure sensor 707 reaches the set parameter, the controller 701 will control the buzzer 708 to produce a buzzing sound, so that the driver will receive a buzzing sound when approaching the vehicle. This solves the problem that after the lower control arm is damaged by an impact and cracks, the cracks will affect the strength and support of the structure. If the damage to the lower control arm is not detected in time, it will pose a safety hazard when the vehicle is in motion.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
