Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to an integral die-cast motor casing. Background Art

[0002] The motor housing is the outer casing for the motor and serves as a protective and support device for the motor when used. First and foremost, it supports and holds the overall structure together. The purpose of the motor housing is to isolate these internal components from human interference or potentially damaging environmental influences. They also minimize the ingress of moisture, dirt or other contaminants that could harm the working parts.

[0003] The existing motor casings include an integrated motor casing and a split motor casing. The integrated motor casing is a whole casing, which is installed vertically, has many accessories and poor consistency. At present, people generally use a split motor casing, which is installed by combining an upper casing and a lower casing, and the lower casing is equipped with a threaded groove for installation. The motor is placed in the motor casing, the central axis is placed in a designated position, the threaded grooves of the upper casing and the lower casing are matched one by one, and the motor is fixed therein by screwing bolts into the threaded grooves. Fewer accessories are used during the installation process, making it more convenient.

[0004] Although the above-mentioned split motor case is good, it still has certain shortcomings. During installation, it is necessary to manually align the empty slots of the upper case and the lower case, and then insert and tighten the bolts one by one. During this process, because the upper case and the lower case have not been fixed, when tightening the first bolt, it is very easy for the upper case and the lower case to move slightly due to the operation of tightening the bolt, causing the remaining holes to be misaligned, and a second alignment is required. This will affect the installation progress and increase the installation time. Therefore, it is urgently necessary to make improvements based on the existing split motor case. Utility Model Content

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure.

[0035] Embodiment 1

[0036] An integral die-cast motor housing, such as Figure 1 - Figure 5 As shown, it includes a motor housing 1.

[0037] Specifically, the motor housing 1 is composed of an upper housing 2 and a lower housing 3 fixed thereto, and upper positioning cylinders 5 are embedded and installed at the bottom ends of both sides of the upper housing 2. Because the upper housing 2 and the upper positioning cylinders 5 are embedded and connected, when the upper housing 2 covers the lower housing 3, the upper positioning cylinders 5 are synchronously covered on the top of the lower housing 3, and bolts 4 for connecting the upper housing 2 and the lower housing 3 are movably installed at the ends of the upper positioning cylinders 5. When the upper housing 2 and the lower housing 3 are fitted together, the bolts 4 installed at the ends of the upper housing 2 can fix the upper housing 2 and the lower housing 3. The outer wall of the lower housing 3 is provided with a threaded connection device 7 corresponding to the upper positioning cylinder 5. When the upper housing 2 is fitted to the lower housing 3, the upper housing 2 synchronously drives the upper positioning cylinder 5 to align with the threaded connection device 7 installed on the outer wall of the lower housing 3, so that it is more convenient for the bolt 4 to fix the upper housing 2 and the lower housing 3. The threaded connection device 7 is provided with a thread groove 13 that matches the thread of the bolt 4. When the bolt 4 fixes the upper housing 2 and the lower housing 3, the setting of the thread groove 13 allows the bolt 4 to In order to tighten the upper housing 2 and the lower housing 3 to make them fit more firmly, a connecting port 12 is fixedly installed on the top of the threaded connection device 7. When the upper housing 2 and the lower housing 3 are fitted together, the upper positioning tube 5 is guided by the connecting port 12, which makes it more convenient for the upper positioning tube 5 to be fixedly connected to the threaded connection device 7. A mounting groove 11 for accommodating the connecting port 12 is provided at the bottom of the upper positioning tube 5. When the upper positioning tube 5 is fixedly connected to the threaded connection device 7, since the bottom of the upper positioning tube 5 is provided with the mounting groove 11 corresponding to the connecting port 12, the upper positioning tube 5 can be aligned more quickly when connected to the threaded connection device 7, thereby reducing the time consumed during installation. In addition, the maximum diameters of the connecting port 12 and the mounting groove 11 are both smaller than the diameters of the upper positioning tube 5 and the threaded connection device 7, so that the connecting port 12 and the mounting groove 11 are convenient for installation at the bottom of the upper positioning tube 5 and the end of the threaded connection device 7, and when the upper positioning tube 5 is connected to the threaded connection device 7, it is easy to align and connect, and will not affect the fit after connection.

[0038] See also Figure 1 - Figure 5 A mounting groove 11 is provided at the bottom of the upper positioning tube 5, and the top of the outer wall of the mounting groove 11 is designed with a slope, and the outer end of the connecting port 12 is also designed with a slope. Under the effect of the slope design, when the upper positioning tube 5 is connected to the threaded connection device 7, it will be guided by the slopes of the end of the connecting port 12 and the end of the mounting groove 11, so that the upper positioning tube 5 and the threaded connection device 7 can be easily aligned and connected.

[0039] See also Figure 1 - Figure 5, a through hole 6 corresponding to the diameter of the bolt 4 is opened in the upper positioning cylinder 5, and the bolt 4 is fixedly connected with the threaded groove 13 through the through hole 6, so that the upper positioning cylinder 5 and the threaded connection device 7 are aligned and connected, and the diameter of the through hole 6 is smaller than the diameter of the mounting groove 11. When the upper positioning cylinder 5 and the threaded connection device 7 are aligned and connected, the bolt 4 passes through the through hole 6 and passes through the middle of the mounting groove 11 to connect with the threaded groove 13, so that when the bolt 4 is tightened and fixed, the connection between the mounting groove 11 and the connecting port 12 is not affected, and the internal diameter of the through hole 6 is the same as the internal diameter of the connecting port 12. In the process of connecting the upper positioning cylinder 5 and the threaded connection device 7, the bolt 4 enters the connecting port 12 through the through hole 6 and is fixedly connected with the threaded groove 13, so that when the bolt 4 is inserted into the upper positioning cylinder 5 and the threaded connection device 7, it is not easy to get stuck, thereby making the installation of the device smoother, more convenient and handy.

[0040] See also Figure 1 - Figure 5 The top of the inner wall of the end of the connection port 12 is designed with an outwardly flared inclined surface. Because the top of the inner wall of the connection port 12 is designed with an outwardly flared inclined surface, the bolt 4 is guided by the inclined surface when entering the connection port 12, so that the bolt 4 can easily enter the connection port 12, and the interface at the top of the connection port 12 is designed in an arrow shape, so that when the upper positioning cylinder 5 is connected with the threaded connection device 7 and the installation groove 11, it is guided by the inclined surface design, so that it becomes easy to connect, and the bolt 4 is guided by the inclined surface when entering, and directly enters the thread groove 13, so that the installation is not affected, and the upper housing 2 and the lower housing 3 are connected. Alignment and connection are easier, and the inner wall of the mounting groove 11 is designed with a magnet, and the outer wall of the connecting port 12 is designed with a magnet that is magnetically attracted to the inner wall of the mounting groove 11. Due to the effect of magnetic attraction, when the mounting groove 11 is connected to the connecting port 12, the magnet will pull the mounting groove 11 and the connecting port 12 to align and connect, so that when the upper shell 2 and the lower shell 3 are fitted, the traction of the magnet will prompt the mounting groove 11 and the connecting port 12 to connect faster, so that the upper shell 2 and the lower shell 3 can be easily fixed together, reducing the installation time, and making the installation process very easy, making the utility model easier to install.

[0041] Embodiment 2

[0042] See also Figure 6 - Figure 8The difference between the second embodiment and the first embodiment is that on the basis of retaining the first embodiment, an upper buckle 9 is fixedly installed at the bottom of the upper housing 2. When the upper housing 2 is fitted with the lower housing 3, the upper buckle 9 is driven to move downward synchronously, so that the upper buckle 9 obtains a downward force, and a lower buckle 8 corresponding to the upper buckle 9 is fixedly installed at the top of the lower housing 3. When the upper housing 2 is fitted with the lower housing 3, the upper buckle 9 is driven to move downward synchronously, so that the upper buckle 9 and the lower buckle 8 are staggered and fitted. The corners where the bottom of the upper buckle 9 is attached to the lower buckle 8 and the corners where the top of the lower buckle 8 is attached to the upper buckle 9 are both beveled, so that when the upper housing 2 and the lower housing 3 are attached, the beveled design of the upper buckle 9 and the lower buckle 8 makes it possible for the upper buckle 9 and the lower buckle 8 to not be pressed against each other when the upper housing 2 and the lower housing 3 are attached, and they are smoothly staggered under the beveled design, so that the upper housing 2 and the lower housing 3 are connected. The bottom of the upper housing 2 is provided with a corresponding to the lower buckle 8. The lower card slot 15 is formed so that when the upper housing 2 and the lower housing 3 are fitted together, the lower card buckle 8 will be staggered with the upper card buckle 9 and embedded in the lower card slot 15, so that the connection process will not cause the housing to get stuck, and the bottom of the lower housing 3 is provided with an upper card slot 14 corresponding to the upper card buckle 9, so that when the upper housing 2 and the lower housing 3 are fitted together, the upper card buckle 9 and the lower card buckle 8 will be fitted together synchronously, and under the action of the upper card slot 14 and the lower card slot 15, the upper card buckle 9 and the lower card buckle 8 are staggered and embedded in the corresponding housing. The upper and lower housings 2 and 3 are connected to each other in a corresponding groove, so that it is very unlikely to get stuck or feel frustrated during the fitting and connection, and the connection process is smooth and unobstructed. In addition, limit blocks 10 are fixedly installed in the upper and lower grooves 14 and 15. When the upper buckle 9 and the lower buckle 8 are embedded and installed in the upper and lower grooves 14 and 15, the limit blocks 10 will limit the movement of the upper and lower buckles 9 and 8, so that after the fitting and connection, there is no gap at the fitting point, thereby improving the sealing of the fitting connection between the upper housing 2 and the lower housing 3.

[0043] See also Figure 6 - Figure 8 The outer walls of the upper buckle 9 and the lower buckle 8 are both provided with a limiting groove 16. When the upper buckle 9 and the lower buckle 8 are embedded in the upper slot 14 and the lower slot 15, the limiting groove 16 is used to fix the buckle and the slot. The size of the limiting groove 16 is the same as the limiting block 10, so that when the limiting block 10 enters the limiting groove 16, the extrusion effect between the limiting block 10 and the limiting groove 16 is better, so that when the upper buckle 9 and the lower buckle 8 are embedded and installed in the upper slot 14 and the lower slot 15, the limiting groove 16 and the limiting block 10 are complementary, and after the motor housing 1 is installed, the limiting groove 16 on the outer walls of the upper buckle 9 and the lower buckle 8 and the limiting block 10 in the upper slot 14 and the lower slot 15 will be buckled and fixed.

[0044] See also Figure 6 - Figure 8The limit block 10 is designed to be cylindrical, so that when the limit groove 16 is fixed to the limit block 10, the limit groove 16 is better fixedly connected to the limit block 10 due to the overall smoothness of the circle, and the limit block 10 is a rubber product. When the upper clip and the lower clip 8 are embedded and installed in the upper slot 14 and the lower slot 15, they will squeeze the limit block 10. Under the elastic effect of the rubber product, it will shrink when squeezed, so that when the upper clip 9 and the lower clip 8 are completely embedded and installed in the upper slot 14 and the lower slot 15, the limit groove 16 just stops at the limit block 10, so that the limit block 10 extends back to its original state in the limit groove 16, so that after the device is installed, it is not easy to shake and the casing will not fall off.
