Description

Technical Field

[0001] The utility model relates to a motor end cover and a motor thereof, belonging to the technical field of vehicle control. Background Art

[0002] In the design and application of motor equipment, the connection between the fan blades and the end cap body has always been a key consideration. Traditional connection methods often rely on complex fixing structures or a large number of fasteners. This not only increases the difficulty and time of installation, but can also cause the connection to loosen due to factors such as vibration and wear during long-term use, thereby affecting the stability and safety of the motor. Especially when the fan blades rotate at high speeds, the centrifugal force generated poses a greater challenge to the connection structure. The slightest carelessness can cause the bolts to loosen, fall off, or even cause more serious accidents. To overcome the shortcomings of traditional connection methods in motor end cap design, a motor end cap and motor are proposed. Utility Model Content

[0003] The purpose of the present utility model is to provide a motor end cover and a motor thereof, so as to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a motor end cover, comprising an end cover body, on which is provided:

[0005] A plurality of mounting grooves, wherein the plurality of mounting grooves are circumferentially distributed on the end cover body;

[0006] A connecting block is arranged in the mounting groove, and one end of the connecting block is connected to the fan blade;

[0007] A bolt is disposed inside the mounting groove, a threaded end of the bolt passes upward through the connecting block and engages with a nut, and the connecting block is provided with a plurality of through holes for the bolts to pass through;

[0008] Wherein, plug-in blocks are provided on both sides of the connecting block, and plug-in slots for plugging in the plug-in blocks are opened on both sides of the installation slot.

[0009] Preferably, a safety pressure plate for crimping the connecting block is provided inside the mounting groove, and a plurality of through holes for bolts to pass through are provided on the side wall of the safety pressure plate, and the through holes on the safety pressure plate correspond one-to-one to the through holes on the connecting block.

[0010] Preferably, a concealed groove for accommodating the plug-in block is provided on one side of the plug-in slot;

[0011] Pin blocks are fixed on both sides of the safety pressure plate, and the pin blocks are inserted into the inside of the insertion slots.

[0012] Preferably, a filling block is fixed on the side wall of the safety pressure plate, and the filling block is inserted into the gap between the mounting groove and the connecting block.

[0013] Preferably, a plurality of recesses are separately provided on the outer wall of the end cover body.

[0014] Preferably, a boss is provided in the middle of the upper end surface of the end cover body, and an axial hole is provided in the middle of the boss.

[0015] Preferably, a plurality of heat dissipation holes are evenly distributed around the boss on the end cover body.

[0035] The end cover body 1 is provided with a plurality of mounting grooves 101, and the plurality of mounting grooves 101 are distributed circumferentially on the end cover body 1;

[0036] The connecting block 2 is arranged in the mounting groove 101, and one end of the connecting block 2 is connected to the fan blade;

[0037] Bolt 3, which is arranged inside the mounting groove 101, with the axis of the bolt 3 perpendicular to the bottom surface of the mounting groove 101. The threaded end of the bolt 3 penetrates the connecting block 2 upward and engages with the nut 301. The connecting block 2 is provided with a plurality of through holes for the bolt 3 to pass through, providing a channel for the bolt 3, so that the bolt 3 can easily penetrate the connecting block 2 and engage with the nut 301;

[0038] Wherein, plug-in blocks 201 are provided on both sides of the connection block 2 , and plug-in slots 102 for plugging in the plug-in blocks 201 are provided on both sides of the installation slot 101 .

[0039] Connect block 2 to the fan blade:

[0040] Integral molding: The connecting block 2 and the fan blade are integrally molded. This design enhances the structural strength between the fan blade and the connecting block 2 and reduces the risk of failure caused by loose connection.

[0041] Plug-in blocks 201: The plug-in blocks 201 on both sides of the connecting block 2 match the plug-in slots 102 on both sides of the installation slot 101, which not only provides additional stability but also simplifies the installation process.

[0042] Installation process and features:

[0043] During installation, first align the plug-in block 201 with the plug-in slot 102, press the connecting block 2 downward, so that the connecting block 2 moves toward the installation slot 101, and at the same time, the plug-in block 201 is inserted into the interior of the plug-in slot 102. Then, insert the bolt 3 into the installation slot 101 from the bottom of the end cover body 1, so that the threaded end of the bolt 3 passes through the through hole of the connecting block 2. At this time, screw the nut 301 onto the threaded end of the bolt 3, and then install the connecting block 2 on the installation slot 101, that is, connect the fan blade to the end cover body 1;

[0044] Enhanced stability: The cooperation between the plug block 201 and the plug slot 102 not only provides additional stability, but also offsets part of the centrifugal force when the fan blade rotates, sharing part of the centrifugal force of the bolt 3; this design extends the service life of the motor end cover and reduces the risk of failure caused by excessive centrifugal force.

At this time, the connecting block 2 is pulled so that the plug-in block 201 slides into the interior of the dark groove 1021. At this time, the safety pressure plate 4 is installed in the installation slot 101. At the same time, the pin block 401 is plugged into the plug-in slot 102. In this way, since the pin block 401 is plugged into the plug-in slot 102, the plug-in block 201 is locked in the interior of the dark groove 1021, thereby increasing the connection block 2 installed in the installation slot 10 1, and when the plug-in block 201 slides into the dark groove 1021 and the safety pressure plate 4 is also installed in the installation groove 101, the through holes on the connecting block 2 and the safety pressure plate 4 are in an aligned state, and the bolt 3 is inserted into the installation groove 101 from the bottom of the end cover body 1, and the threaded end of the bolt 3 passes through the through holes of the connecting block 2 and the safety pressure plate 4. At this time, the nut 301 is screwed onto the threaded end of the bolt 3, and then the connecting block 2 is installed on the installation groove 101, that is, the fan blade is connected to the end cover body 1.

[0050] like Figure 5 and Figure 6 As shown, when the plug-in block 201 slides into the interior of the dark groove 1021, the connecting block 2 slides in the installation groove 101 to generate a gap. In order to fill the gap between the connecting block 2 and the installation groove 101 and further increase the stability of the installation of the connecting block 2,

[0051] A filling block 402 is fixed on the side wall of the safety pressure plate 4 , and the filling block 402 is inserted into the gap between the installation groove 101 and the connecting block 2 .
