Description

Technical Field

[0001] This invention relates to the field of electric control assembly technology for new energy vehicles, specifically to an assembly structure and assembly method for an electric control system of a new energy vehicle. Background Technology

[0002] Automotive electronic control, or automotive electronic control system, is basically composed of sensors, electronic controllers (ECUs), drivers, and control software. It works in conjunction with the vehicle's mechanical systems and transmits information to each other via cables or radio waves, achieving "electromechanical integration." Existing new energy vehicle electronic control systems include multiple control functional modules. The mounting brackets for these control functional modules occupy a large space, making adjustment and installation inconvenient. Furthermore, the protective structures of the mounting brackets are complex, hindering disassembly and maintenance by personnel and resulting in low operational efficiency. We have designed a mounting bracket for a new energy vehicle electronic control system.

[0003] For example, Chinese Patent Publication No. CN213056951U includes a lower vehicle body mounting plate. The lower vehicle body mounting plate has an integrated protective frame plate. Vertical screw rods are vertically fixed at the four corners of the top surface of the protective frame plate. An upper baffle is provided above the protective frame plate. The upper baffle and the vertical screw rods at the four corners are slidably inserted and assembled. Insert plates are slidably installed in slots opened on the four side plates of the protective frame plate. The insert plates are integrally structured on the bottom surface of the upper baffle. Multiple electronic control module mounting strips are provided at the bottom of the inner cavity of the protective frame plate. The two side ends of the multiple electronic control module mounting strips are slidably mounted on horizontal screw rods. The two sides of the horizontal screw rods are fixedly connected to the inner sidewall of the protective frame plate. This technical solution has a simple structure, is easy to disassemble and install, and is convenient to operate and apply.

[0004] The existing technology has the following problems:

[0005] Existing new energy vehicle electronic control systems consist of multiple control functional modules. The mounting brackets for these modules occupy a significant amount of space. The mounting methods for electronic control system instruments typically involve screw fixing, glue injection, or direct welding to the vehicle frame. These methods provide limited stability for the instruments but make later adjustment, installation, or disassembly inconvenient. Furthermore, the complex protective structures of the mounting brackets hinder maintenance and reduce operational efficiency. Therefore, we have designed a mounting bracket for new energy vehicle electronic control systems. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0008] In a first aspect, a new energy vehicle electronic control system assembly structure includes an electronic control system assembler body, the electronic control system assembler body including a limiting snap-fit ​​mechanism, the limiting snap-fit ​​mechanism including an overlapping base, and a limiting fixing mechanism detachably installed on the front and rear outer surfaces of the overlapping base.

The downward limiting unit is provided on the top outer surface of the limiting snap unit.

[0010] The limiting and fixing mechanism includes a pushing limiting unit and a squeezing extension unit, wherein the squeezing extension unit is disposed on the outer surface of the pushing limiting unit.

[0011] A further improvement of the technical solution of the present invention is that: the compression protection unit includes an elastic soft plate that is detachably installed on the inner surface of the bottom of the overlapping base, and a gap is provided between the two sides of the elastic soft plate and the inner wall of the overlapping base.

[0012] A further improvement of the technical solution of the present invention is that: the limiting snap-fit ​​unit includes a C-shaped snap-fit ​​sleeve that is movably overlapped on the inner wall of the overlap base, and sliding holes are provided on the outer surfaces of both sides of the overlap base.

[0013] A further improvement of the technical solution of the present invention is that: the pressing and limiting unit includes a compression head fixedly connected to the top outer surface of the C-shaped snap-fit ​​sleeve, the inner bottom surface of the compression head is provided with a compression upper sliding groove, and the top outer surface of the compression upper sliding groove and located at one edge position are provided with a snap-fit ​​groove.

[0014] A further improvement of the technical solution of the present invention is that: the pushing and limiting unit includes a threaded rotating rod, and an overlapping limiting sleeve fixedly connected to one side of the outer surface of the overlapping base is movably sleeved on the outer surface of the threaded rotating rod, and one end of the threaded rotating rod extends through the overlapping limiting sleeve to the outer surface, and a rotating handle is provided on one end of the threaded rotating rod, and burr welding points are provided on the front and rear outer surfaces of the overlapping limiting sleeve.

[0015] A further improvement of the technical solution of the present invention is that: a limiting slide rod is fixedly connected to the inner surfaces of both sides of the overlapping limiting sleeve, and a slider is movably sleeved on the outer surfaces of the threaded rotating rod and the limiting slide rod.

[0016] A further improvement of the technical solution of the present invention is that: the extrusion extension unit includes a push rod that is movably overlapped on the inner surface of the sliding hole, and a conical extrusion block is provided on the bottom surface of one end of the push rod, and the outer surface of the conical extrusion block is movably overlapped on the inner surface of the extrusion sleeve.

[0018] Secondly, a method for assembling a new energy vehicle electronic control system includes the following steps:

[0019] Step 1, Overlap Welding Unit: Place the overlap base and overlap limiting sleeve in a suitable position inside the car, weld the burr welding points, use the burr welding points to increase the welding area, and limit the position of the overlap base and burr welding points.

[0020] Step 2, Limiting and placing the electrical control assembly structure: Place the electrical control unit on the top outer surface of the elastic soft plate, and then overlap it on the surface of the electrical control unit with a C-type snap-fit ​​sleeve.

[0021] Step 3: Press and fix the unit: Rotate the threaded rotating rod to push the slider, and cooperate with the conical pressing block on one end of the pushing rod to press the C-type snap-fit ​​sleeve to increase its snap-fit ​​force.

[0024] 2. This invention provides an assembly structure and assembly method for a new energy vehicle electronic control system. The rotating threaded rod pushes the slider, causing the push rod to slide on the inner surface of the sliding hole. When the slider slides, the position of the slider is limited by the limiting slide rod.

As the conical extrusion block is continuously pressed down, it extrudes the C-shaped snap-fit ​​sleeve. The C-shaped snap-fit ​​sleeve is used to limit and snap the position of the electronic control system device, increasing its snap-fit ​​force. In later use, it is used in conjunction with a wind source cooling mechanism to cool the electronic control system device. Attached Figure Description

A compression protection unit is provided on the inner bottom surface of the overlapping base 21. The limiting and locking mechanism 2 and the downward pressing limiting mechanism 3 are movably overlapped on the inner wall surface of the overlapping base 21. The downward pressing limiting mechanism 3 is provided on the top outer surface of the limiting and locking mechanism 21. The compression protection unit includes a detachably installed... The elastic flexible plate 22 is attached to the inner surface of the bottom of the base 21. There is a gap between the two sides of the elastic flexible plate 22 and the inner wall of the overlapping base 21. The limiting snap-fit ​​unit includes a C-shaped snap-fit ​​sleeve 24 that is movably attached to the inner wall of the overlapping base 21. Sliding holes 23 are provided on the two outer sides of the overlapping base 21. The pressing limiting unit includes a compression sleeve 25 that is fixedly connected to the top outer surface of the C-shaped snap-fit ​​sleeve 24. A compression upper sliding groove 26 is provided on the inner bottom surface of the compression sleeve 25. A snap-fit ​​groove 27 is provided on the top outer surface of the compression upper sliding groove 26 and at one edge position.

[0039] Furthermore, the overlapping base 21 and the overlapping limiting sleeve 31 are placed in a suitable position inside the car, and the burr welding point 32 is welded to increase the welding area. The position of the overlapping base 21 and the burr welding point 32 is limited. The electronic control system 5 is placed on the top outer surface of the elastic flexible plate 22. The gap between the elastic flexible plate 22 and the overlapping base 21 is used to limit and lock the bottom position of the C-type snap sleeve 24, thereby increasing the sealing. The C-type snap sleeve 24 is then overlapped on the surface of the electronic control system 5. The elasticity of the elastic flexible plate 22 is used to limit its position and prevent tilting and shaking.

[0040] Example 2

[0041] like Figure 1-6As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the limiting and fixing mechanism 3 includes a pushing limiting unit and a pressing and extending unit. The pressing and extending unit is disposed on the outer surface of the pushing limiting unit. The pushing limiting unit includes a threaded rotating rod 33. An overlapping limiting sleeve 31, which is fixedly connected to the outer surface of one side of the overlapping base 21, is movably sleeved on the outer surface of the threaded rotating rod 33. One end of the threaded rotating rod 33 extends through the overlapping limiting sleeve 31 to the outer surface. A rotating handle is provided on one end of the threaded rotating rod 33. Burr welding points 32 are provided on the front and rear outer surfaces of the overlapping limiting sleeve 31. Limiting slide rods 34 are fixedly connected to the inner surfaces of both sides of the overlapping limiting sleeve 31. A slider 35 is movably sleeved on the outer surfaces of the threaded rotating rod 33 and the limiting slide rod 34. The pressing and extending unit includes a pushing rod 36 movably overlapping the inner surface of the sliding hole 23. A conical pressing block 37 is provided on the bottom surface of one end of the pushing rod 36. The outer surface of the conical pressing block 37 is movably...

Air source cooling mechanisms 4 are detachably installed on the outer surfaces of the left and right sides of the overlapping base 21. Rotating the threaded rotating rod 33 pushes the slider 35, causing its pushing rod 36 to slide on the inner surface of the sliding hole 23. When the slider 35 slides, it cooperates with the limiting sliding rod 34 to control the slider 35. The position of 5 is limited, and when the conical extrusion block 37 on one end of the push rod 36 slides inside the extrusion sleeve 25, the conical extrusion block 37 is tilted at an angle to the surface of the extrusion groove 26 to extrude. As the conical extrusion block 37 is continuously pressed down, it extrudes the C-type snap-fit ​​sleeve 24. The C-type snap-fit ​​sleeve 24 is used to limit and snap the position of the electronic control system device 5, increasing its snap-fit ​​force. In later use, it is used in conjunction with the air source cooling mechanism 4 to blow air to cool the electronic control system device 5.

[0042] Example 3

[0043] like Figure 1-6 As shown, the present invention provides a method for assembling a new energy vehicle electronic control system, which includes the following steps:

[0044] Step 1, Overlap Welding Unit: Place the overlap base 21 and overlap limiting sleeve 31 in a suitable position inside the car, weld the burr welding point 32, use the burr welding point 32 to increase the welding area, limit the position of the overlap base 21 and the burr welding point 32, place the electronic control system 5 on the top outer surface of the elastic soft plate 22, use the gap between the elastic soft plate 22 and the overlap base 21 to limit and snap the bottom position of the C-type snap sleeve 24, and at the same time increase the sealing performance.

[0045] Step 2, Limiting and placing the electrical control assembly structure: Place the electrical control system 5 on the top outer surface of the elastic soft plate 22, and then overlap it on the surface of the electrical control system 5 by means of the C-type snap-fit ​​sleeve 24. Use the elasticity of the elastic soft plate 22 to limit its position and prevent tilting and shaking.

[0046] Step 3, Extrusion Fixing Unit: Rotate the threaded rotating rod 33 to push the slider 35, causing its pushing rod 36 to slide on the inner surface of the sliding hole 23. When the slider 35 slides, it is limited by the limiting sliding rod 34. When the conical extrusion block 37 on one end of the pushing rod 36 slides inside the extrusion sleeve 25, the inclination angle of the conical extrusion block 37 extrudes the surface of the upper sliding groove 26. As the conical extrusion block 37 continues to press down, it extrudes the C-type snap-fit ​​sleeve 24. The C-type snap-fit ​​sleeve 24 is used to limit and snap the position of the electronic control system 5, increasing its snap-fit ​​force. In later use, it is used in conjunction with the air source cooling mechanism 4 to blow air to cool the electronic control system 5.

[0047] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
