Description

Technical Field

[0001] This utility model relates to the field of electric drive axle power recovery equipment installation technology, and in particular to an electric drive axle power recovery equipment with intelligent switching mode. Background Technology

[0002] Intelligent switching mode electric drive axle energy recovery equipment is a device that uses electric drive technology to recover energy. It is commonly used in vehicles or heavy machinery and other mobile devices. The electric drive axle refers to the axle in the vehicle driven by an electric motor, which is responsible for driving the wheels and providing power. This type of axle is generally more efficient and environmentally friendly than traditional internal combustion engine drive systems. The energy recovery equipment is a device that can convert and store the excess energy generated by the vehicle during braking or downhill driving into electrical energy for later use. This process is often called regenerative braking. It can automatically switch between recovery and power output modes according to the vehicle's operating status, load, terrain changes, and other conditions. For example, during braking, the equipment can automatically switch to energy recovery mode to convert the energy generated during braking into electrical energy, while during acceleration or driving, it efficiently provides power, thus achieving intelligent switching. It is widely used in the fields of electric vehicles, hybrid vehicles, and heavy machinery.

[0003] In existing technologies, the electric drive axle is the core of the entire power system. The energy recovery device is generally installed inside the electric drive axle or in conjunction with the electric motor. This location facilitates the direct recovery of energy generated during braking and its conversion into electrical energy. The electrical energy generated by the energy recovery device is usually sent to the vehicle's battery pack for storage. However, when the main body of the electric drive axle needs to be installed on the vehicle chassis, its weight is relatively heavy. When workers install it, they need to rely on external equipment or drag it themselves, which increases the labor intensity of the workers and makes it impossible to install it quickly, reducing the efficiency of disassembly, repair, or replacement. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing equipment requires external equipment or its own support during installation, which increases the labor intensity for workers. Therefore, this invention proposes an intelligent switching mode electric drive axle power recovery device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent switching mode electric drive axle power recovery device, comprising a vehicle floor and an electric drive axle body, wherein two connecting plates are fixedly installed at the bottom of the electric drive axle body, and positioning blocks are fixedly installed at the bottom of each of the two connecting plates, and a first limiting hole is provided on one side of the outer wall of each of the two positioning blocks; two strip-shaped columns are fixedly installed at the top of the vehicle floor, and strip-shaped grooves are provided at the top of each of the two strip-shaped columns, and a strong spring is fixedly installed on one side of the inner wall of each of the two strip-shaped grooves, and a T-shaped insert is fixedly installed on one side of the outer wall of each of the two strong springs, wherein the outer walls of the two T-shaped inserts are movably embedded in the interior of the two strip-shaped grooves, and the outer walls of the two T-shaped inserts are movably inserted into the interior of the two first limiting holes; a second limiting hole is provided on one side of the inner wall of each of the two strip-shaped columns, and the outer walls of the two T-shaped inserts are movably inserted into the interior of the two second limiting holes.

[0006] Preferably, a connecting rod is fixedly installed on one side of the outer wall of each of the two T-shaped inserts.

[0007] Preferably, a first circular hole is provided on one side of the outer wall of each of the two strip columns, and the outer walls of the two connecting rods are movably inserted into the two first circular holes.

[0008] Preferably, a strip handle is fixedly installed on one side of the outer wall of each of the two connecting rods, and a dust-shielding plate is fixedly installed on the top of each of the two T-shaped inserts.

[0009] Preferably, two mounting blocks are fixedly installed at the bottom of the electric drive axle body, and a fixing hole is provided on one side of the outer wall of each of the two mounting blocks.

[0010] Preferably, two rectangular posts are fixedly installed on the top of the vehicle floor.

[0011] Preferably, the top of each of the two rectangular columns is provided with a rectangular hole, and the outer walls of the two mounting blocks are movably inserted into the interior of the two rectangular holes.

[0012] Preferably, a second circular hole is provided on one side of the outer wall of each of the two rectangular columns, and the inner surface of the two second circular holes is connected to the interior of the two fixing holes.

[0013] Preferably, the inner walls of the two fixing holes are threaded with fixing bolts, and the outer walls of the two fixing bolts are movably inserted into the two second circular holes.

[0014] Preferably, two protective plates are fixedly installed on the outer wall of the electric drive axle body.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, when the electric drive axle body needs to be installed under the vehicle floor, the two connecting rods and two T-shaped inserts are first moved by the two strip handles. At this time, the two strong springs are in a compressed state. Then, the electric drive axle body and the two positioning blocks are placed in the two strip grooves. Then, the two strip handles are released. Under the action of the two strong springs, the two T-shaped inserts are moved and pass through the first limiting holes on the two positioning blocks and are inserted into the two second limiting holes. Thus, the two positioning blocks are limited in the two strip columns, and the electric drive axle body is initially limited under the vehicle floor. There is no need for workers to use external equipment or drag it by themselves, which reduces the labor intensity of workers and enables rapid installation, improving the efficiency of disassembly, repair or replacement.

[0017] In this invention, when the electric drive axle body is positioned on the vehicle floor, its two mounting blocks are located precisely within the rectangular holes of the two rectangular posts. Then, through the action of two fixing bolts, it passes through the two second circular holes and is threaded into the two fixing holes, allowing it to be quickly installed at the corresponding position under the vehicle floor. Furthermore, the two protective plates prevent external dirt from splashing onto the electric drive axle body, providing a protective effect and improving its service life.

[0025] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-5 As shown, this utility model provides an intelligent switching mode electric drive axle power recovery device, including a vehicle floor 1 and an electric drive axle body 2. Two connecting plates 3 are fixedly installed at the bottom of the electric drive axle body 2, and positioning blocks 4 are fixedly installed at the bottom of each of the two connecting plates 3. A first limiting hole 5 is opened on one side of the outer wall of each of the two positioning blocks 4. Two strip-shaped columns 6 are fixedly installed at the top of the vehicle floor 1, and strip-shaped grooves 7 are opened at the top of each of the two strip-shaped columns 6. A strong spring 8 is fixedly installed on one side of the inner wall of each of the two strip-shaped grooves 7, and a T-shaped insert 9 is fixedly installed on one side of the outer wall of each of the two strong springs 8. The outer walls of the two T-shaped inserts 9 are movably embedded in the two... Inside the strip groove 7, and the outer walls of the two T-shaped inserts 9 are movably inserted into the two first limiting holes 5. The inner walls of the two strip columns 6 are each provided with a second limiting hole 10, and the outer walls of the two T-shaped inserts 9 are movably inserted into the two second limiting holes 10. A connecting rod 11 is fixedly installed on one side of the outer wall of the two T-shaped inserts 9. A first round hole 12 is provided on one side of the outer wall of the two strip columns 6, and the outer walls of the two connecting rods 11 are movably inserted into the two first round holes 12. A strip handle 13 is fixedly installed on one side of the outer wall of the two connecting rods 11. A dust-shielding plate 14 is fixedly installed on the top of the two T-shaped inserts 9.

[0028] The overall effect of Embodiment 1 is as follows: when the electric drive axle body 2 needs to be installed under the vehicle floor 1, the two connecting rods 11 are moved by the two strip handles 13, so that the two connecting rods 11 move in the first round holes 12 on the two strip pillars 6, and drive the two T-shaped inserts 9 to one side. Since there are strong springs 8 installed between the two T-shaped inserts 9 and one side of the inner wall of the two strip grooves 7, the two strong springs 8 can be squeezed and put into a compressed state. At this time, the electric drive axle body 2 is gradually placed under the vehicle floor 1, and the two connecting plates 3 and two positioning blocks 4 installed on its top can be inserted into the two strip grooves 7 at the same time. Then, the two strip handles 13 are released. Since there are first limiting holes 5 on the two positioning blocks 4 and second limiting holes 1 on one side of the inner wall of the two strip pillars 6, the electric drive axle body 2 is gradually placed under the vehicle floor 1. 0, thus, under the action of two strong springs 8, it drives the two T-shaped inserts 9 to move and pass through the first limiting holes 5 on the two positioning blocks 4, and at the same time inserts them into the two second limiting holes 10, thereby limiting the two positioning blocks 4 into the two strip columns 6, so that the electric drive axle body 2 can be initially limited under the vehicle floor 1. It does not require the staff to borrow external equipment or drag it by themselves, reducing the fatigue of the staff, thereby realizing the quick installation and improving the efficiency of disassembly, repair or replacement. Secondly, through the action of the two dust-proof plates 14, when the two T-shaped inserts 9 move, the two dust-proof plates 14 are always above the two strong springs 8, effectively preventing foreign objects or dust from accumulating inside and causing the movement to be unsmooth, thus playing a dust-proofing effect.

[0029] Example 2: As Figures 2-5 As shown, two mounting blocks 15 are fixedly installed at the bottom of the electric drive axle body 2. Fixing holes 16 are opened on one side of the outer wall of each mounting block 15. Two rectangular posts 17 are fixedly installed at the top of the vehicle floor 1. Rectangular holes 18 are opened on the top of each rectangular post 17. The outer walls of the two mounting blocks 15 are movably inserted into the interior of the two rectangular holes 18. A second round hole 19 is opened on one side of the outer wall of each rectangular post 17. The inner surface of each second round hole 19 is connected to the interior of the two fixing holes 16. Fixing bolts 20 are threadedly connected to the inner surface of each fixing hole 16. The outer surface of each fixing bolt 20 is movably inserted into the interior of the two second round holes 19. Two protective plates 21 are fixedly installed on the outer wall of the electric drive axle body 2.

[0030] The effect achieved by the entire embodiment 2 is that when the electric drive axle body 2 is initially positioned on the vehicle floor 1, the two mounting blocks 15 installed on its top are exactly located in the rectangular holes 18 opened on the top of the two rectangular posts 17. Since fixing holes 16 are opened on both mounting blocks 15 and second round holes 19 are opened on both rectangular posts 17, the two fixing bolts 20 are used to pass through the second round holes 19 opened on the two rectangular posts 17 and are threaded into the fixing holes 16 on the two mounting blocks 15. Thus, it can be quickly installed in the corresponding position under the vehicle floor 1. Secondly, protective plates 21 are installed on both sides of the electric drive axle body 2, which can effectively prevent external mud from splashing onto the electric drive axle body 2 and the equipment on it, thus providing a protective effect and improving the service life of the electric drive axle power recovery equipment.

[0031] Working principle: First, when the electric drive axle body 2 needs to be installed under the vehicle floor 1, the two connecting rods 11 are moved by the two bar handles 13, causing the two T-shaped inserts 9 to move and compress the two strong springs 8. Then, the two connecting plates 3 and two positioning blocks 4 installed on the top of the electric drive axle body 2 are placed in the two bar grooves 7. At this time, the two bar handles 13 are released, and under the action of the two strong springs 8, the two T-shaped inserts 9 are moved, passing through the first limiting holes 5 opened on the two positioning blocks 4, and inserted into the second limiting holes 10 opened inside the two bar posts 6. Thus, the two positioning blocks 4 can be moved. By limiting the electric drive axle body 2 within the two strip pillars 6, it can be initially positioned below the vehicle floor 1. At this time, the two mounting blocks 15 installed on the top of the electric drive axle body 2 are exactly located within the rectangular holes 18 opened on the top of the two rectangular pillars 17. Then, through the action of the two fixing bolts 20, it passes through the two second round holes 19 and is threaded into the two fixing holes 16. Thus, it can be quickly installed in the corresponding position below the vehicle floor 1 without the need for workers to use external equipment or drag it by themselves, reducing the labor intensity of workers and enabling rapid installation, thereby improving the efficiency of disassembly, repair, or replacement.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
