Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The following is for reference. Figures 1-4 Description of the integrated structure 100 of motor mount and lower tube according to an embodiment of the present utility model.

[0029] Example 1

[0030] like Figure 1 As shown, this utility model embodiment provides an integrated structure 100 for a motor base and a lower tube, which includes a motor base 1 and a lower tube 2. The motor base 1 has a mounting port 114, and the lower tube 2 is connected to the motor base 1 for mounting a battery; wherein the mounting port 114 communicates with the lower tube 2 for inserting or removing the battery.

[0031] In related technologies, the mounting port on the motor mount is only used for disassembling and assembling the motor. An additional battery access port is provided on the side wall of the lower tube. After the battery is installed in place, the battery access port is sealed with a cover.

[0032] In the integrated structure 100 of motor mount and lower tube provided in this embodiment, by connecting the mounting port 114 to the lower tube 2, the mounting port 114 on the motor mount 1 is not only used for mounting the motor, but also provides a convenient channel for battery installation and removal. Operators can use this mounting port 114 to smoothly place the battery in the lower tube 2, or conveniently remove the battery when maintenance or replacement is required. As a result, the opening on the side wall of the lower tube 2 is eliminated, the structural strength of the integrated structure 100 of motor mount and lower tube is improved, the assembly step of the cover is further eliminated, the assembly process is reduced, and the assembly efficiency is improved.

[0033] In a specific example, the motor housing 1 has a mounting cavity 12 and a mounting port 114, the mounting port 114 being connected to the mounting cavity 12, and the lower tube 2 being connected to the mounting cavity 12 through a connecting port 3.

[0034] Example 2

[0035] like Figure 1 and Figure 2 As shown, the lower tube 2 further includes a first tube segment 21 and a second tube segment 22, with the second tube segment 22 connected to the motor base 1 via the first tube segment 21. The first tube segment 21 is used to install the battery, and the diameter of the second tube segment 22 is smaller than that of the first tube segment 21. Thus, when the battery enters the lower tube 2 from the mounting port 114 and extends into the first tube segment 21, once the battery reaches the preset position, based on the structural feature that the diameter of the second tube segment 22 is smaller than that of the first tube segment 21, the position of the battery can be initially positioned, effectively preventing the battery from sliding out from the end of the first tube segment 21 away from the motor base 1, thereby further improving the ease of assembly.

[0036] Compared with related technologies, the natural limit formed by the difference in pipe diameter allows the smaller diameter of the second pipe section 22 to restrict the movement of the battery within the first pipe section 21 after the battery is installed in place. This reduces the need for additional positioning components or complex positioning operations, achieves positioning by using simple pipe diameter changes, reduces assembly difficulty and time costs, improves assembly efficiency, and is conducive to the large-scale production and manufacturing of products.

[0037] like Figure 1 and Figure 2 As shown, further, the diameter of the second pipe segment 22 gradually decreases in the direction away from the first pipe segment 21. After the battery is in place, the constraint structure formed by the gradually decreasing pipe diameter can effectively buffer the collision between the battery and the second pipe segment 22 during the assembly process, thereby reducing the risk of damage to the battery due to the collision.

[0038] like Figure 2 As shown, in a specific embodiment, the lower tube 2 has a mid-plane 201 parallel to its own extension direction, and the distance between the tube walls on both sides of the mid-plane 201 and the mid-plane 201 is the same; along the direction away from the first tube segment 21, the tube walls on both sides of the second tube segment 22 gradually approach the mid-plane 201. The constraint structure formed by the gradually decreasing tube diameter can effectively buffer the collision between the battery and the second tube segment 22 during the assembly process, thereby reducing the risk of damage to the battery due to the collision.

[0039] It should be noted that the median plane 201 mentioned here is not an actual solid plane. The median plane 201 is a reference plane introduced to clearly describe the shape and structure of the second pipe segment 22.

[0040] Example 3

[0041] like Figure 2 and Figure 3 As shown, a wire-passing hole 221 is further provided on the wall of the second pipe section 22. The wire-passing hole 221 allows the electrical connector for connecting the battery to pass through. By setting the wire-passing hole 221 on the second pipe section 22, the electrical connector can be moved away from the motor base 1, thereby facilitating its retraction, reducing interference between the electrical connector and other components, improving the reliability and safety of the overall structure, and reducing the risk of failure due to wiring interference.

[0042] like Figure 2 and Figure 3 As shown, the first pipe segment 21 is further provided with a battery mounting structure 213, which includes a battery mounting hole that penetrates the wall of the first pipe segment 21. Fasteners can pass through the battery mounting hole and connect and fix the battery, thereby fixing the battery in the first pipe segment 21 and improving the stability and reliability of the connection between the battery and the first pipe segment 21.

[0043] like Figure 2 and Figure 3 As shown, the battery mounting structure 213 further includes at least two, with at least one located at one end of the first tube segment 21 and at least one located at the other end of the first tube segment 21. By providing mounting structures at both ends, the battery can be fixed from multiple directions, further enhancing the stability of the battery within the first tube segment 21, reducing the displacement of the battery due to vibration, shaking, or other reasons during equipment operation, and improving the stability and reliability of the connection between the battery and the first tube segment 21.

[0044] Example 4

[0045] like Figure 4 As shown, the motor base 1 includes a first end wall 111, a second end wall 112, and a surrounding wall 113. The first end wall 111, the second end wall 112, and the surrounding wall 113 enclose an inner mounting cavity 12. The surrounding wall 113 has an mounting opening 114 for communicating with the inner mounting cavity 12. Both the first end wall 111 and the second end wall 112 have a hollow area 115. The hollow area 115 communicates with the mounting opening 114 and is used to avoid the motor drive shaft, thereby increasing the area of ​​the mounting opening 114.

[0046] The lower tube 2 is connected to the enclosure wall 113. Specifically, the lower tube 2 has a battery inlet, and the enclosure wall 113 has a notch spaced apart from the mounting port 114. The notch is opposite to the battery inlet to form a communication port 3 structure and connect the lower tube and the mounting cavity 12, thereby connecting the mounting port 114 and the lower tube 2.

[0047] In a specific example, a motor mounting structure 13 is provided on the inner surfaces of the first end wall 111 and the second end wall 112. The hollow area 115 connects to the mounting port 114, which can avoid the motor mounting structure 13, thereby reducing interference between the battery and the motor mounting structure 13 during the battery assembly process.

[0048] Example 5

[0049] like Figure 1 and Figure 2As shown, the first pipe segment 21 further includes a variable cross-section pipe 211 and a constant cross-section pipe 212. The variable cross-section pipe 211 is connected between the constant cross-section pipe 212 and the motor base 1. The diameter of the variable cross-section pipe 211 gradually increases along the direction closer to the motor base 1. Dividing the first pipe segment 21 into a variable cross-section pipe 211 and a constant cross-section pipe 212, with the variable cross-section pipe 211 connected between the constant cross-section pipe 212 and the motor base 1, this design takes into account different functional requirements. The constant cross-section pipe 212 provides a stable space for the battery, ensuring its stability within the pipe; while the gradually increasing diameter of the variable cross-section pipe 211 facilitates convenient battery installation while providing more space near the motor base 1, allowing for better connection and optimizing the overall structural mechanical performance and space utilization efficiency.

In the description of the present invention, "first feature" and "second feature" may include one or more of the features.
