Description

Technical Field

[0001] The utility model belongs to the technical field of electric forklifts, in particular to an electric forklift motor. Background Art

[0002] Synchronous reluctance motors have excellent performance in energy conversion efficiency and have many advantages. They can more efficiently convert electrical energy into mechanical energy, thereby reducing energy waste, and are often used in electric forklifts.

[0003] The motor generates a large amount of heat when in use. If it is not discharged to the outside of the motor housing in time, the accumulated heat will cause the motor to burn out and shorten its service life. In the patent with authorization announcement number CN207069767U, a motor housing with efficient heat dissipation function is disclosed, which mainly utilizes the corresponding upper and lower air vents of the heat dissipation ribs to enable the motor housing to effectively dissipate heat. In order to prevent excessive dust from entering the interior of the motor housing, a dustproof net is also provided in the inner cavity of the heat dissipation rib. After long-term use, the dustproof net will inevitably be clogged, resulting in poor heat dissipation effect. After this situation occurs, the dustproof net cannot be conveniently disassembled, cleaned or replaced, and can only be solved by replacing the heat dissipation ribs, resulting in unnecessary waste of the heat dissipation ribs.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 FIG. 1 is a three-dimensional schematic diagram of a motor in an embodiment. Figure 2 What is shown is a schematic diagram of a planar cross-sectional structure of a motor in an embodiment; Figure 3 It is shown that Figure 2 A schematic diagram of the structure enlargement in the middle;

[0023] The device includes:

[0024] The motor body 10 includes a housing 11;

[0025] The heat dissipation structure includes an embedding groove 21 symmetrically provided on the outer side of the housing 11, and a cover 22 is detachably mounted on the open end of the embedding groove 21;

[0026] A plurality of through holes 23 are formed on the bottom wall of the embedded groove 21, and a plurality of through holes 24 are formed on the cover body 22. The through holes 23 and the through holes 24 are connected to the inside of the housing 11 and the outside. A dust screen 25 is also provided between the through holes 23 and the through holes 24 in the embedded groove 21, and a pressing block 26 is provided at one end of the cover body 22 close to the dust screen 25.

[0027] When the cover body 22 is closed, the pressing block 26 presses the dustproof net 25 tightly against the embedding groove 21 to restrict its movement.

[0028] The through hole 1 23 and the through hole 24 are evenly arranged in a plurality to play a role in heat dissipation. The dustproof net 25 is flatly arranged between the through hole 1 23 and the through hole 24 to prevent the dust entering from the through hole 24 from further entering the housing 11 through the through hole 1 23 and affecting the internal structure.

[0029] By movably embedding the dustproof net 25 in the embedding groove 21, the dustproof net 25 can be quickly taken out by disassembling the cover body 22, and the dustproof net 25 can be replaced or cleaned, thereby realizing the repeated use of the dustproof net 25 and saving costs; and by the pressing block 26 provided on the cover body 22, the edge of the dustproof net 25 is pressed when the cover body 22 is closed, so that the installation and fixation of the dustproof net 25 is realized, avoiding that the dustproof net 25 is not stably installed inside the embedding groove 21 and thus affecting the dustproof effect. At the same time, this structure makes the installation and disassembly of the dustproof net 25 more convenient, and only the cover body 22 needs to be disassembled.

[0030] The pressing blocks 26 are symmetrically arranged on both sides of the cover body 22 to press the edges of both sides of the dustproof net 25 without affecting the heat dissipation effect of the through hole 1 23 and the through hole 24 and the dustproof effect of the dustproof net 25 .

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, Figure 1 FIG. 1 is a three-dimensional schematic diagram of a motor in an embodiment. Figure 2What is shown is a schematic diagram of a planar cross-sectional structure of a motor in an embodiment; Figure 3 It is shown that Figure 2 A schematic diagram of the structure enlargement in the middle;

[0032] Specifically, the embedding groove 21 is set to be T-shaped, and the dustproof net 25 is set on the step inside the embedding groove 21, and there is a gap between the bottom wall inside the embedding groove 21 and the cover body 22;

[0033] By placing both sides of the dustproof net 25 on the steps, it is convenient to determine the installation position of the dustproof net 25;

[0034] The cover 22 is further comprised of a locking member 27, which can be detachably locked. The locking member 27 comprises a threaded column 271, a through hole three and a nut 272. The threaded column 271 is arranged on one end of the shell 11 close to the cover 22, and the through hole three is arranged at a position on the cover 22 corresponding to the threaded column 271. After the through hole three passes through the threaded column 271, the nut 272 is screwed on the top end of the threaded column 271 to lock the cover 22 on the open end of the embedding groove 21 of the shell 11.

[0035] The nut 272 matches the threaded column 271, and in this embodiment, there are four sets of threaded columns 271 and through holes 271, which are respectively located at the four corners of the cover body 22, so as to ensure that the cover body 22 can be stably installed;

[0036] The locking member 27 is provided to realize the detachable installation of the cover body 22. When the cover body 22 is covered on the open end of the embedding groove 21, the three through holes are correspondingly inserted into the threaded column 271, and finally the nut 272 is screwed on the threaded column 271 to realize the locking of the cover body 22. When removing the cover body 22, the nut 272 is screwed out in the opposite direction, and then the cover body 22 is removed.

[0037] The outer side wall of the cover body 22 is also provided with a plurality of heat dissipation fins 28 , and the dissipation fins 28 and the second through hole 24 are not arranged at the same position; the evenly arranged heat dissipation fins 28 serve to further improve the heat dissipation effect.

[0038] Working principle: When the motor body 10 has excellent heat dissipation performance, the device is provided with a dustproof net 25 to prevent dust from the heat dissipation holes, and the dustproof net 25 can be easily disassembled and replaced. The operation steps are as follows: unscrew and remove the nut 272, and then remove the cover body 22. At this time, the dustproof net 25 inside the embedded groove 21 loses the pressure of the pressing block 26, and is in an active state, so it can be easily taken out, cleaned or replaced, and the dustproof net 25 is placed on the step inside the embedded groove 21, and the cover body 22 is closed. After the cover body 22 is closed, the pressing block 26 presses the dustproof net 25 tightly against the embedded groove 21, and then the cover body 22 is locked by the locking piece 27.

[0039] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
