Detailed implementation mode

[0045] To make the content easier to be clearly understood, the following will be further described in detail according to specific embodiments in conjunction with the accompanying drawings;

[0046] A gearbox motor for an ice crusher solves the technical problem of relatively poor sealing performance in the related art, can be manufactured and used, and achieves the positive effect of relatively good sealing performance and improved waterproof performance. The general idea is as follows:

[0047] One implementation mode:

[0048] As Figure 1 、 Figure 2 shown; a gearbox motor for an ice crusher includes: a housing 10, the housing 10 has a raised edge 11, and an opening space 11-1 is formed inside the raised edge 11; a circuit connection board 20, connected to the housing 10 and disposed at the opening space 11-1; a connection wire 30, one end of which is connected to the circuit connection board 20 and the other end passes through the opening space 11-1; and an upper cover 40, connected to the raised edge 11 and covering the opening space 11-1;

[0049] It is characterized in that it further includes: a seal 100, connected to the notch 11-2 on the raised edge 11;

[0050] When the connection wire 30 passes through the opening space 11-1 and extends along the notch 11-2 to the outside of the housing 10, the seal 100 is penetrated by the connection wire 30, and the seal 100 wraps a part of the connection wire 30;

[0051] And when the upper cover 40 is connected to the raised edge 11, one end of the seal 100 is closely attached to the upper cover 40;

[0052] Specifically, during implementation, a seal 100 is provided. The seal 100 is connected to a notch 11-2 on a raised edge 11 of the housing 10. When the connection line 30 passes through the opening space 11-1 and extends along the notch 11-2 to the outside of the housing 10, the seal 100 is penetrated by the connection line 30, and the seal 100 wraps around a part of the connection line 30. When the upper cover 40 is connected to the raised edge 11, one end of the seal 100 is pressed against the upper cover 40. The seal 100 forms a reliable sealing structure with the raised edge 11, the connection line 30, and the upper cover 40 at the notch 11-2, with relatively good sealing performance, ensuring the waterproof performance.

[0053] Another implementation method:

[0054] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 shown; during implementation, after the seal 100 is inserted into the notch 11-2, a part of it is arranged in the opening space 11-1, and the other part protrudes from the raised edge 11; it is beneficial for the seal 100 to be stuck in the notch 11-2 and not fall off, which is relatively beautiful.

[0055] The seal 100 includes: a first part 101, which is inserted into the notch 11-2; a second part 102, which is connected to one side of the first part 101, arranged in the opening space 11-1, and contacts the inner wall of the raised edge 11; a third part 103, which is connected to the other side of the first part 101, is arranged at an interval from the second part 102, and contacts the outer wall of the raised edge 11; and two through holes 104, which are arranged at intervals, and the through holes 104 penetrate through the first part 101, the second part 102, and the third part 103 and are penetrated by the connection line 30. The seal 100 is made of a soft material, such as rubber. The first part 101, the second part 102, the third part 103, and the through holes 104 are integrally formed. When the first part 101 is inserted into the notch 11-2, the second part 102 and the third part 103 are attached to the raised edge 11, which is beneficial for the seal 100 to be stuck in the notch 11-2 and not fall off, and also ensures the sealing performance. The through holes 104 wrap around a part of the connection line 30, ensuring the sealing performance at the connection with the connection line 30.

[0056] The first part 101, the second part 102 or the third part 103 is a square block structure; the width dimension of the first part 101 is smaller than the width dimension of the second part 102; the width dimension of the second part 102 is smaller than the width dimension of the third part 103; the length dimension of the second part 102 or the third part 103 is greater than the length dimension of the first part 101; one side wall A in the width direction on the first part 101 and one side wall B in the width direction on the second part 102 are in the same plane; one side wall C in the width direction on the third part 103 is higher than the A or the B, and an "L" - shaped structure is formed between the C and the A and the B; there are two symmetrically - arranged rounded corners 105 on the other side wall in the width direction of the first part 101, the second part 102 or the third part 103; the control of the shape and size of the seal 100 is beneficial for the seal 100 to be stuck at the notch 11 - 2 without falling off, which is relatively beautiful, and the "L" - shaped structure formed between the C and the A and the B can be closely attached to the upper cover 40, ensuring the sealing performance and improving the waterproof performance;

[0057] Another embodiment:

[0058] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 shown; during implementation, the raised edge 11 includes: a first raised portion 11 - 3 having the notch 11 - 2; a second raised portion 11 - 4 spaced from the first raised portion 11 - 3; and two third raised portions 11 - 5 arranged opposite to each other and connected between the first raised portion 11 - 3 and the second raised portion 11 - 4;

[0059] The height dimension of the second raised portion 11 - 4 is greater than the height dimension of the first raised portion 11 - 3;

[0060] The top of the third raised portion 11 - 5 is inclined from the connection with the second raised portion 11 - 4 towards the connection with the first raised portion 11 - 3, forming an inclined structure. Compared with the prior art (such as Figure 8) The fitting between the first vertical surface 1001-2 on the first raised edge 1001 of the second housing 1000 and the second vertical surface 2001 on the third housing 2000. The inclined structure of the third protrusion 11-5 not only increases the contact area between the raised edge 11 and the upper cover 40, but also does not cause interference during assembly and is conducive to ensuring the quality of ultrasonic welding (when the ultrasonic welding head welds vertically downward, the pressure received by the vertical surface during welding is relatively small, and gaps are likely to be generated between the vertical surfaces, resulting in relatively poor sealing performance);

[0061] After the combination of the first protrusion 11-3, the second protrusion 11-4, and the third protrusion 11-5, they form a complete surrounding space, and the surrounding space is the opening space 11-1;

[0062] There is a raised edge 11 provided. A complete surrounding space is formed between the first protrusion 11-3, the second protrusion 11-4, and the third protrusion 11-5, and the surrounding space is the opening space 11-1. Compared with the prior art (such as Figure 7 ) on the first raised edge 1001 of the second housing 1000, there is a missing section 1001-1. The contact area between the raised edge 11 and the upper cover 40 is relatively large. After ultrasonic welding, the connection reliability between the two is relatively good, and the sealing performance is relatively good;

[0063] Among them, there is also an inner stop 11-6 on the top of the raised edge 11; the inner stop 11-6 is arranged along the shapes of the second protrusion 11-4, the third protrusion 11-5, and the first protrusion 11-3; the dimension D at the depth of the inner stop 11-6 is the same at the first protrusion 11-3, the second protrusion 11-4, or the third protrusion 11-5; the inner stop 11-6 communicates with the opening space 11-1 to form a stepped structure; the inner stop 11-6 is partially engaged with the upper cover 40; by providing the inner stop 11-6 and engaging it with the outer stop 44 on the upper cover 40, the assembly positioning is relatively convenient, and the contact area between the raised edge 11 and the upper cover 40 is increased. After ultrasonic welding, the connection reliability between the two is relatively good, and the sealing performance is relatively good;

[0064] Among them, the top surface E (the top of the first protrusion 11-3) of the raised edge 11 near the seal 100 is lower than the A or the B; the dimension by which the surface E is lower than the A or the B is 0.05 mm. By controlling the dimension, after ultrasonic welding between the raised edge 11 and the upper cover 40, the first cover plate 41 on the upper cover 40 can closely adhere to the seal 100, causing the seal 100 to be squeezed, which is conducive to ensuring the sealing performance between the seal 100, the raised edge 11, the connection line 30, and the upper cover 40;

[0065] Another embodiment:

[0066] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 shown; during implementation, the upper cover 40 includes: a first cover plate 41, which contacts the top of the first protrusion 11-3, the A, the B, and the third part 103; a second cover plate 42, which contacts the top of the second protrusion 11-4; a third cover plate 43, which is connected between the first cover plate 41 and the second cover plate 42 and contacts the top of the third protrusion 11-5; and an outer stop 44, which is connected to the bottom surfaces of the first cover plate 41, the second cover plate 42, and the third cover plate 43, avoids the seal 100, and snaps into the inner stop 11-6;

[0067] The first cover plate 41, the second cover plate 42, the third cover plate 43, and the outer stop 44 are integrally injection-molded. The assembly and positioning of the outer stop 44 and the inner stop 11-6 are relatively convenient. The contact area between the upper cover 40 and the protrusion rib 11 is relatively large. After ultrasonic welding, the connection reliability between the two is relatively good, and the sealing performance is relatively good;

[0068] Another embodiment:

[0069] As Figure 1 、 Figure 2 、 Figure 7 、 Figure 8 shown; during implementation, it further includes: a shell cover 50, which is connected to the shell 10; a mounting bracket 60, which is connected between the shell 10 and the shell cover 50; a DC motor 70, which is connected to the mounting bracket 60, is arranged between the shell 10 and the shell cover 50, and is electrically connected to the circuit connection board 20; and a gear transmission assembly 80, which is connected between the shell 10, the shell cover 50, and the mounting bracket 60 and is driven to rotate by the DC motor 70;

[0070] The circuit connection board 20, the connecting wire 30, the shell cover 50, the mounting bracket 60, the DC motor 70, and the gear transmission assembly 80 are common structures in the prior art and are common general knowledge. A person of ordinary skill in the art can directly and unambiguously know how to set them after seeing the disclosed content, without the need to perform creative labor or excessive experiments;

[0071] The working principle is as follows: The seal 100 is connected to the notch 11-2 on the convex rib 11 on the housing 10; when the connecting wire 30 passes through the opening space 11-1 and extends along the notch 11-2 to the outside of the housing 10, the seal 100 is penetrated by the connecting wire 30, and the seal 100 wraps a part of the connecting wire 30; when the upper cover 40 is connected to the convex rib 11, one end of the seal 100 is in close contact with the upper cover 40; the seal 100 forms a reliable sealing structure between the convex rib 11, the connecting wire 30 and the upper cover 40 at the notch 11-2, with relatively good sealing performance, ensuring the waterproof performance;
