Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor housing technology, and in particular to a new energy vehicle motor housing with a modular structure. Background Technology
[0002] With the rapid development of new energy vehicle technology, the motor, as a core power component, directly affects the overall vehicle's operating efficiency and reliability. The motor housing, as a crucial protective and supporting structure, is increasingly adopting a modular design approach, which is becoming an important way to improve the motor's overall performance, optimize manufacturing processes, and reduce costs.
[0003] In existing technologies, the housing of new energy vehicle motors is typically used to protect the motor and enable some functional expansion. However, existing new energy vehicle motor housings have many shortcomings in practical use. For example, during maintenance of the electrical interfaces of traditional motor housings, it is necessary to remove numerous screws and untangle complex wiring one by one, requiring more professional maintenance personnel and auxiliary equipment, resulting in high labor and material costs. Furthermore, repeated and complex disassembly can easily damage the interfaces and surrounding components, increasing maintenance and replacement costs and making the entire process cumbersome. In addition, during routine inspections, the inconvenience of inspecting the electrical interfaces of traditional motor housings makes it difficult to detect potential problems in a timely manner, such as loose wiring or wear, which may lead to the escalation of faults and pose certain safety hazards. Therefore, how to design a modular new energy vehicle motor housing that enables rapid inspection of the electrical interfaces, thereby reducing maintenance and replacement costs, has become a key issue in new energy vehicle motor housing technology. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a new energy vehicle motor housing with a modular structure.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a new energy vehicle motor housing with a modular structure, comprising: a housing, an electrical interface module snapped onto one side of the housing, inserting rods at both ends of the electrical interface module, mounting posts fixedly installed at both ends of the middle portion of one side of the housing, a screw threadedly connected to one end of the middle portion of the mounting post, an inner conical surface formed on the inner wall of one end of the screw, a base plate fixedly installed on the other side of the middle portion of the mounting post, and multiple elastic plates uniformly fixedly installed on one side of the electrical interface module, each of the multiple elastic plates having an arc-shaped conical block fixedly installed at one end, the multiple elastic plates being located away from... The inner diameter of one end of the base plate is larger than the inner diameter of the elastic plate near the base plate. Multiple arc-shaped cones slide in fit with the inner cone surface. Slots are provided in the middle of the screw, mounting post, and base plate. The inner diameter of the multiple elastic plates near the base plate is the same as the inner diameter of the slot. The insertion rod is inserted into the middle of the slot. The inner diameter of the inner cone surface is larger than the inner diameter of the slot. The inner sides of the multiple arc-shaped cones abut against the insertion rod. An L-shaped rod is fixedly installed on one side of each of the two mounting posts. A screw is threaded to one end of the L-shaped rod. An arc-shaped groove is provided on the outer side of the middle of one end of the screw. One end of the screw slides and engages with the middle of the arc-shaped groove.
[0006] In a preferred embodiment, the electrical interface module is snapped into place by inserts on both sides and mounting posts mounted on the housing.
[0007] In a preferred embodiment, multiple wiring terminals are uniformly fixedly installed in the middle of the electrical interface module, and indicator lights are fixedly installed on both sides of the middle of the electrical interface module.
[0008] In a preferred embodiment, each of the four corners of the lower end of the housing is fixedly equipped with a support foot, and the lower end of each of the support feet is fixedly equipped with a rubber pad.
[0009] In a preferred embodiment, a front cover plate is fixedly installed at one end of the housing.
[0010] In a preferred embodiment, a motor output shaft slot is provided through the middle of one end of the front cover plate and the housing.
[0011] In a preferred embodiment, a slot is provided on the outer side of the middle part of the other end of the housing, and a rear cover plate is fixedly connected to the middle part of the slot by bolts.
[0012] In a preferred embodiment, a motor mounting groove is provided in the middle of the housing.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In use, the electrical interface module is engaged with the mounting posts on the housing via plugs at both ends, simplifying maintenance. During maintenance, simply rotate the screw in the opposite direction to eliminate the pressure exerted by the inner cone on the arc-shaped cone, allowing the elastic plate to return to its original shape. The plugs and electrical interface module can then be easily removed, enabling quick disassembly and reducing after-sales maintenance and time costs. During installation, align the plug with the slot and insert it. Then rotate the screw to apply inward pressure to the arc-shaped cone, causing the elastic plate to grip the plug, thus completing the installation.
[0015] 2. In use, the rubber pads installed at the lower end of the support feet of this utility model have excellent shock absorption and cushioning performance. During motor operation, a certain amount of vibration and noise will be generated. The rubber pads can effectively absorb and disperse this vibration energy, reducing the impact on the surrounding environment. At the same time, the rubber pads can also act as a buffer, protecting the motor from damage caused by vibration and extending the service life of the equipment. Attached Figure Description

[0029] Example 1: As Figure 1-6 As shown, this utility model provides a technical solution: a new energy vehicle motor housing with a modular structure, comprising: a housing 1, an electrical interface module 2 snapped onto one side of the housing 1, with plug rods 20 inserted into both ends of the electrical interface module 2, mounting posts 21 fixedly installed at both ends of the middle part of one side of the housing 1, a screw 25 threadedly connected to one end of the middle part of the mounting post 21, an inner conical surface 26 formed on the inner wall of one end of the screw 25, a base plate 22 fixedly installed on the other side of the middle part of the mounting post 21, and multiple elastic plates 23 uniformly fixedly installed on one side of the electrical interface module 2, with an arc-shaped conical block 24 fixedly installed at one end of each of the multiple elastic plates 23, the inner diameter of the multiple elastic plates 23 away from the base plate 22 being larger than the inner diameter of the elastic plates 23 near the base plate 22, and multiple... The arc-shaped cone 24 slides with the inner cone surface 26. The screw 25, the mounting post 21, and the middle of the base plate 22 are all provided with slots 27. The inner diameter of the multiple elastic plates 23 near the end of the base plate 22 is the same as the inner diameter of the slot 27. The insertion rod 20 is inserted into the middle of the slot 27. The inner diameter of the inner cone surface 26 is larger than the inner diameter of the slot 27. The inner side of the multiple arc-shaped cones 24 abuts against the insertion rod 20. An L-shaped rod 29 is fixedly installed on one side of each of the two mounting posts 21. A screw 30 is threaded to one end of the L-shaped rod 29. An arc-shaped groove 28 is provided on the outer side of the middle of one end of the screw 25. One end of the screw 30 slides and engages with the middle of the arc-shaped groove 28. The electrical interface module 2 is engaged with the mounting post 21 installed on the housing 1 through the insertion rods 20 on both sides.
[0030] In this embodiment, multiple elastic plates 23 and their arc-shaped conical blocks 24, which are uniformly fixed on one side of the electrical interface module 2, can slide and engage with the inner conical surface 26 of one end of the screw 25 on the mounting post 21. When installing the electrical interface module 2, the insertion rods 20 on both sides of the electrical interface module 2 are aligned with the slots 27 and pushed inward until they reach the bottom. Then, the screw 25 is rotated. As the screw 25 moves along the threaded groove, the inner conical surface 26 at the other end exerts an inward squeezing force on the arc-shaped conical block 24, causing the multiple elastic plates 23 to tightly grip the insertion rods 20. This achieves a tight connection between the electrical interface module 2 and the mounting post 21. This tight fit not only improves the stability of the connection but also effectively prevents the insertion rods 20 from shaking within the slots 27, reduces wear caused by vibration, extends the service life of the connecting components, and ensures reliable connection of the electrical interface under various working conditions. The screw 30 on the L-shaped rod 29 can slide and engage with the arc-shaped groove 28 on the screw 25. After the screw 25 is rotated and tightened, the user can rotate the screw 30 to limit the screw 25, ensuring the stability of the connection and preventing the screw 25 from loosening due to vibration or other factors. This ensures that the electrical interface module 2 is firmly connected to the housing 1 and can work stably during vehicle operation. When it is necessary to maintain, replace, or adjust the electrical interface module 2, first reverse the screw 30 to remove the limit on the screw 25, and then rotate the screw 25 in the opposite direction to make the squeezing force of the inner conical surface 26 on the arc-shaped conical block 24 disappear. Then the elastic plate 23 will return to its original shape. At this time, the insertion rod 20 can be easily pulled out from the slot 27, thereby realizing the quick disassembly of the electrical interface module 2. This facilitates the maintenance personnel to inspect and maintain its internal parts, reducing after-sales maintenance costs and time costs.
[0031] Example 2: As Figure 1-3 As shown, multiple wiring terminals 18 are evenly fixedly installed in the middle of the electrical interface module 2. Indicator lights 19 are fixedly installed on both sides of the middle of the electrical interface module 2. Support feet 16 are fixedly installed at the four corners of the lower end of the housing 1. Rubber pads 17 are fixedly installed at the lower ends of the multiple support feet 16. A front cover plate 11 is fixedly installed at one end of the housing 1. A motor output shaft slot 12 is formed between the front cover plate 11 and the middle of one end of the housing 1. A slot 14 is formed on the outer side of the middle of the other end of the housing 1. A rear cover plate 15 is fixedly connected to the middle of the slot 14 by bolts. A motor fixing slot 13 is formed in the middle of the housing 1.
[0032] In this embodiment, multiple terminals 18 evenly fixedly installed in the middle of the electrical interface module 2 provide standardized and centralized connection points between the motor and the external electrical system, making the motor's electrical wiring neater and easier for installation and maintenance personnel to operate. Indicator lights 19 fixedly installed on both sides of the middle of the electrical interface module 2 provide real-time feedback on the motor's operating status. Support feet 16 fixedly installed at the four corners of the lower end of the housing 1 provide a stable support structure for the motor. Rubber pads 17 fixedly installed at the lower end of the support feet 16 have good shock absorption and buffering performance, absorbing and dispersing the vibration energy generated during motor operation, thus acting as a buffer to protect the motor. To protect the motor and mounting surfaces from damage caused by vibration and extend the service life of the equipment, the front cover plate 11 fixedly installed at one end of the housing 1 not only protects the internal components of the motor, but also provides a stable rotation channel for the motor output shaft. The slot 14 opened on the outer side of the middle of the other end of the housing 1 and the rear cover plate 15 fixed by bolts achieve sealing and protection of the rear end of the motor. The motor fixing slot 13 opened in the middle of the housing 1 provides accurate positioning and fixing points for the motor installation, so that the motor can be firmly installed in the motor fixing slot 13, ensuring that the motor will not be displaced or shaken during operation, thus ensuring the stability and reliability of the motor.
