[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] See also Figure 1-9 An embodiment of the present invention provides an integrated structure of a front end cover and a housing of a motor, comprising a housing 1, a front end cover 2 and a rear end cover 3, wherein the front end cover 2 and the rear end cover 3 are respectively located at two ends of the housing 1, and the front end cover 2 is integrally formed with the housing 1, a reinforcement frame 4 is installed inside the housing 1, an elastic member 5 abutting against one end of the reinforcement frame 4 is installed on the inner side of the front end cover 2, a plurality of clamping members 6 clamped with the other side of the reinforcement frame 4 are installed on the inner side of the housing 1, a spinning pop-up mechanism 7 is installed inside the rear end cover 3, and the spinning pop-up mechanism 7 abuts against the clamping member 6, when the rear end cover 3 is directly opened, the position of the reinforcement frame 4 is fixed, and when the rear end cover 3 is rotated to open, the reinforcement frame 4 is forced to move toward the rear end cover 3 through the spinning pop-up mechanism 7.

[0034] Specifically, the front end cover 2 and the shell 1 are made of an integrated cold-rolled plate stretching process, and the casing part is a cold-rolled stretched plate with a thickness of 1.2 mm, which reduces the sealing ring between the front end cover 2 of the motor and the shell 1, improves the sealing performance of the product, and the front end cover 2 does not need to be screwed, reducing labor and material costs. The reinforcement frame 4 is used to improve the structural strength inside the shell 1 and facilitate component installation. The reinforcement frame 4 is connected to the shell 1 through an elastic member 5 and a snap-on member 6. The elastic member 5 applies a force to the reinforcement frame 4 so that the reinforcement frame 4 and the snap-on member 6 are firmly snapped together. The snap-on member 6 is used to prevent the reinforcement frame 4 from moving into the rear end cover 3 under the force of the elastic member 5, thereby further enhancing the structural stability of the motor. When the internal components of the motor need to be repaired or replaced, the rear end cover 3 is rotated, and the spinning pop-up mechanism 7 can force the reinforcement frame 4 toward the rear end cover 3-direction movement to achieve quick disassembly of the reinforcement frame 4, the added spin-pressed pop-up mechanism 7 can allow the reinforcement frame 4 and the components in the reinforcement frame 4 to be quickly and conveniently disassembled when needed, thereby simplifying the maintenance process and improving maintenance efficiency, and can also keep the reinforcement frame 4 stable in the shell 1 when the rear end cover 3 is opened, and the rear end cover 3 is directly opened (that is, without rotating), and the reinforcement frame 4 remains in place due to the fixing effect of the clamping member 6 and does not move. Only when the rear end cover 3 is rotated open, the spin-pressed pop-up mechanism 7 will force the clamping member 6 to release the fixation on the reinforcement frame 4, and the elastic member 5 will push the reinforcement frame 4 to move in the direction of the rear end cover 3, so that the reinforcement frame 4 can be easily disassembled to facilitate maintenance or replacement of components inside the motor, so that the maintenance work can be flexibly adjusted according to needs.

[0035] Compared with the prior art, the embodiment of the present invention greatly simplifies the assembly process and reduces the production cost by designing the front end cover 2 and the shell 1 as an integrated structure, while improving the overall sealing performance and structural strength of the motor. An elastic member 5 that abuts against one end of the reinforcement frame 4 is installed on the inner side of the front end cover 2, and a clamping member 6 that is clamped with the other side of the reinforcement frame 4 is installed on the inner side of the shell 1, thereby achieving a stable installation and fixation of the reinforcement frame 4. When the rear end cover 3 is rotated open, the spin-pressed pop-up mechanism 7 forces the reinforcement frame 4 to move toward the rear end cover 3 under the action of the elastic member 5, and the components in the shell 1 are further extracted by moving the reinforcement frame 4 outward, which not only improves the structural strength of the motor, but also makes it possible to conveniently disassemble and replace the components in the motor shell 1 when needed.

[0036] In a further embodiment of the present invention, a shaft sleeve 8 is inserted into the front end cover 2, and a plurality of limit rods 801 are distributed in an annular manner on the outer circumference of the shaft sleeve 8. A plug-in frame 101 adapted to the limit rod 801 is installed at the connection between the inner side of the front end cover 2 and the shell 1. The plug-in frame 101, the front end cover 2 and the shell 1 are integrally formed. The end of the limit rod 801 is inserted into the plug-in frame 101 and abuts against the inner wall of the shell 1. An anti-slip ring 201 that is clamped with the shaft sleeve 8 is installed on the outer side of the front end cover 2. Specifically, a shaft sleeve 8 is inserted into the front end cover 2, and the shaft sleeve 8 is used to support and fix the rotating shaft of the motor. The outer circumference of the shaft sleeve 8 A plurality of limiting rods 801 are distributed in the upper ring, which not only enhance the structural strength of the sleeve 8, but also play a positioning role. When the sleeve 8 is inserted into the front end cover 2, the end of the limiting rod 801 is aligned with the plug-in frame 101, so that the end of the limiting rod 801 enters the plug-in frame 101 and abuts against the inner wall of the housing 1. This design ensures the stability and firmness of the sleeve 8 in the front end cover 2, and prevents the sleeve 8 from loosening or falling off during the operation of the motor. In order to further enhance the stability of the sleeve 8, an anti-slip ring 201 that is engaged with the sleeve 8 is also installed on the outside of the front end cover 2. The design of the anti-slip ring 201 not only limits the axial movement of the sleeve 8, but also improves the anti-rotation ability of the sleeve 8, thereby ensuring that the rotating shaft of the motor can operate stably and reliably.

[0037] In a further embodiment of the present invention, the outer wall of the shell 1 is provided with a plurality of integrally formed reinforcing rib rods 102, one end of the reinforcing rib rod 102 is connected to the front end cover 2, the plurality of reinforcing rib rods 102 and the plurality of limiting rods 801 are staggered with each other, and the outer wall of the shell 1 is further provided with a plurality of rib plates between two adjacent reinforcing rib rods 102. Specifically, one end of the reinforcing rib rod 102 is tightly connected to the front end cover 2, ensuring the integrity and stability between the front end cover 2 and the shell 1, the reinforcing rib rod 102 effectively disperses the stress and vibration borne by the shell 1, the positions of the plurality of reinforcing rib rods 102 and the plurality of limiting rods 801 in the shell 1 are all different, which can maximize the overall structural strength of the integrally formed front end cover 2 and the shell 1 and ensure its service life.

[0038] In a further embodiment of the present invention, the elastic member 5 includes a gasket 501 installed on the inner side of the front end cover 2, one side of the gasket 501 is abutted against a plurality of limit rods 801, and an abutment groove 503 adapted to the limit rods 801 is provided on the gasket 501, and the other side of the gasket 501 is fixedly connected to a top spring 502 for pressing the reinforcement frame 4. Specifically, after the sleeve 8 is fixed, the pressure of the limit rod 801 can be used to prevent the gasket 501 from deflecting, thereby ensuring the stability of the position of the entire elastic member 5, allowing one end of the top spring 502 to always abut against the reinforcement frame 4, and then under the action of the top spring 502, the reinforcement frame 4 is always in contact with the clamping member 6 to prevent the two from accidentally loosening and affecting the normal operation of the motor.

[0039] In a further embodiment of the present invention, the clamping member 6 includes a docking rod 601 axially fixed to the inner wall of the shell 1, a slide groove 401 matching the docking rod 601 is opened on the outer side of the reinforcement frame 4, and a baffle 602 is slidably connected to the end of the docking rod 601 close to the rear end cover 3, and a connecting spring 603 is installed between the baffle 602 and the docking rod 601. Specifically, during the motor assembly process, the reinforcement frame 4 first slides along the docking rod 601 through its own slide groove 401 to a predetermined installation position, so that the reinforcement frame 4 maintains a correct installation angle. As the reinforcement frame 4 completely enters the shell 1, the originally compressed baffle 602 moves toward the center of the shell 1 under the action of the connecting spring 603, and then blocks the outer side of the reinforcement frame 4, thereby preventing the reinforcement frame 4 from moving toward the direction of the rear end cover 3, thereby ensuring the stability of the reinforcement frame 4.

[0040] In a further embodiment of the present invention, the spin-pressed pop-up mechanism 7 includes a pressure ring 701 fixed in the rear end cover 3, and one side of the pressure ring 701 is fixedly connected to an arc-shaped pressure strip 702, and one side of the arc-shaped pressure strip 702 is abutted against the baffle 602. Specifically, during the operation of the motor, no relative rotation will occur between the rear end cover 3 and the shell 1, and the spin-pressed pop-up mechanism 7 remains in a locked state to ensure a firm connection between the reinforcement frame 4 and the shell 1. The baffle 602 also always abuts against one end of the reinforcement frame 4. When the motor needs to be disassembled or maintained, the rear end cover 3 can be rotated to make the arc-shaped pressure strip 702 on the pressure ring 701 slide along the edge of the baffle 602. During this process, the arc-shaped pressure strip 702 gradually increases the pressure on the baffle 602, so that the connecting spring 603 is compressed. As the baffle 602 moves in the opposite direction, the locking relationship between the baffle 602 and the reinforcement frame 4 is released, and the baffle 602 moves away from one end of the reinforcement frame 4, allowing the reinforcement frame 4 to easily pop out a distance and allow the entire baffle 602 to enter the slide groove 401 of the reinforcement frame 4, thereby simplifying the disassembly process of the motor and improving maintenance efficiency.

[0041] In a further embodiment of the present invention, the rear end cover 3 is connected to the shell 1 through a plurality of spiral fasteners 9, and a screw hole 103 for the spiral fastener 9 to pass through is provided on the shell 1, and an arc-shaped adjustment groove 104 is provided on the shell 1 at the top of the screw hole 103, and the screw hole 103 is communicated with the arc-shaped adjustment groove 104. Specifically, the rear end cover 3 is inserted into the screw hole 103 on the shell 1 by a plurality of spiral fasteners 9 installed thereon to complete the assembly of the motor housing. If the rear end cover 3 of the motor needs to be disassembled for maintenance, the spiral fastener 9 can be directly screwed out completely from the screw hole 103 and the arc-shaped adjustment groove 104. At this time, the rear end cover 3 can be directly opened, and if it is necessary to subsequently repair the components at a deeper position inside the shell 1 During maintenance, the spiral fastener 9 can be loosened so that only the rod head part is screwed out of the screw hole 103, that is, the rod head of the spiral fastener 9 is placed in the arc-shaped adjustment groove 104. At this time, under the limitation of the spiral fastener 9, the rear end cover 3 can neither be opened directly nor be rotated to a certain angle to fine-tune the connection angle between the rear end cover 3 and the shell 1. The flexibility of the arc-shaped adjustment groove 104 is utilized to move the spiral fastener 9 along the arc-shaped adjustment groove 104, so that the spin-pressed pop-up mechanism 7 in the rear end cover 3 can stably squeeze and push the clamping part 6, avoiding the rotation of the rear end cover 3 when the spin-pressed pop-up mechanism 7 and the clamping part 6 are staggered, thereby simplifying the disassembly process and improving the accuracy and reliability of the motor maintenance.

[0042] In a further embodiment of the present invention, a marking groove 901 is provided on the spiral fastener 9. When the bottom end of the spiral fastener 9 is located in the arc-shaped adjustment groove 104, the marking groove 901 is exposed. Specifically, the marking groove 901 is set at a conspicuous position of the rod of the spiral fastener 9. When the spiral fastener 9 is tightened and passes through the arc-shaped adjustment groove 104 and the screw hole 103 of the shell 1, the marking groove 901 is located inside the rear end cover 3. When the marking groove 901 is not visible, it means that the spiral fastener 9 has been threadedly connected with the screw hole 103. When the spiral fastener 9 is loosened and its bottom end is located in the arc-shaped adjustment groove 104, the marking groove 901 will be exposed outside the rear end cover 3. This design allows the operator to intuitively confirm that the rod head of the spiral fastener 9 has reached the position of the arc-shaped adjustment groove 104. At this time, the rear end cover 3 can be rotated without directly separating the rear end cover 3 and the shell 1, thereby avoiding the problem of the reinforcement frame 4 being difficult to remove due to improper operation.

[0043] In a further embodiment of the present invention, a socket 402 for the insertion of the plug-in frame 101 is provided at one end of the reinforcement frame 4, and a wedge-shaped groove 403 for abutting and cooperating with the blocking piece 602 is provided at one end of the slide groove 401. Specifically, during the assembly process, the plug-in frame 101 is further aligned with the socket 402 of the reinforcement frame 4 to ensure a tight fit between the two after the reinforcement frame 4 is pushed in. The plug-in frame 101 is used to further ensure the accuracy of the installation position of the reinforcement frame 4. When the reinforcement frame 4 enters the shell 1, the blocking piece 602 will slide along the inclined surface of the wedge-shaped groove 403 until it is tightly abutted in the slide groove 401 of the reinforcement frame 4, allowing the blocking piece 602 to automatically avoid the entering reinforcement frame 4, and the installation and disassembly process is simpler and faster.

[0044] In a further embodiment of the present invention, a support bracket 404 is installed at one end of the reinforcement frame 4 close to the rear end cover 3, and an axial hole 405 is opened in the center of the support bracket 404. Specifically, during the assembly process, the support bracket 404 is installed at the end of the reinforcement frame 4 close to the rear end cover 3, and cooperates with the rear end cover 3 and the motor spindle through the axial hole 405, so that the support bracket 404 can effectively support and fix the rear end cover 3 and its internal components to prevent them from being displaced or loosened during operation. At the same time, the addition of the support bracket 404 also enhances the overall strength and stability of the reinforcement frame 4, making the entire structure more sturdy and durable. This optimized design not only improves the reliability and service life of the product, but also helps to reduce maintenance costs and failure rates.

[0045] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
