Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor technology, specifically relating to a brushless motor that is easy to disassemble and repair. Background Technology
[0002] Brushless motors are a typical example of modern electromechanical products. Compared to traditional brushed motors, brushless motors offer advantages such as low noise, high energy efficiency, and durability. Brushless motors generally operate in a self-controlled manner, so unlike synchronous motors that require heavy-load starting under variable frequency speed control, they typically do not need to restart the windings on the rotor. This means they are unlikely to experience oscillations or loss of synchronization during sudden load changes, which is a key advantage and a major reason for their widespread use.
[0003] The existing brushless motor housing and cover are usually fixedly connected by welding. Although this connection method is strong, it is difficult to disassemble and assemble, and it is inconvenient for staff to inspect the internal parts of the brushless motor as needed. After disassembling and inspecting the brushless motor, it is difficult to reassemble it, and the cost of manual adjustment is too high, so it is not very practical. Utility Model Content
[0004] To address the problems mentioned in the background art, this utility model provides a brushless motor that is easy to disassemble and repair, solving the problems of difficult disassembly and assembly of brushless motors, inconvenience for staff to inspect the internal parts of brushless motors, and difficulty in reassembly after disassembly.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a brushless motor that is easy to disassemble and maintain, comprising a housing, a lower end cover on one side of the bottom of the housing, an upper end cover on one side of the top of the housing, a bolt on one side of the surface of the upper end cover, one end of the bolt penetrating the interior of the upper end cover and being threaded into the interior of one side of the housing, a first snap-fit groove on one side of the surface of the housing, a second snap-fit groove on the other side of the surface of the housing, a first snap-fit block fixedly connected to one side of the surface of the lower end cover, and the surface of the first snap-fit block being movably connected to the surface of the first snap-fit groove, and a second snap-fit block fixedly connected to one side of the surface of the upper end cover, and the surface of the second snap-fit block being movably connected to the surface of the second snap-fit groove.
[0006] Preferably, a bearing mounting part is connected to the middle of the surface of the lower end cover, an output shaft is connected to one side of the surface of the bearing mounting part, and a rotating shaft is connected to one end of the output shaft.
[0007] Preferably, multiple sets of heat dissipation vents are formed around the surface of the outer casing, and the positions of the multiple sets of heat dissipation vents correspond one-to-one.
[0008] Preferably, a connecting plate is connected to the inner surface of the outer shell, a rubber-coated stator is connected to one side of the surface of the connecting plate, and a magnetic ring is provided on one side of the inner surface of the outer shell, with the inner surface of the magnetic ring in contact with the outer surface of the rubber-coated stator.
[0009] Preferably, a handle is fixedly connected to one end of the surface of the lower end cover.
[0010] Preferably, there are three sets of the first and second card slots, and the positions of the three sets of the first and second card slots correspond to each other.
[0011] Preferably, there are three sets of both the first and second latching blocks, and the positions of the first and second latching blocks correspond to each other.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The brushless motor is assembled by the interlocking of the first locking block, the second locking block, the first locking slot, the second locking slot, and the bolts. The outer shell, the upper cover, and the lower cover are connected in a movable manner. The upper and lower covers can be engaged or disengaged from the outer shell by simply turning the upper and lower covers by five to eight degrees. The positions of the three sets of first locking blocks, second locking blocks, first locking slots, and second locking slots are corresponding to each other. This corresponding position design simplifies the disassembly and assembly process, facilitates operation by staff, and reduces manual adjustment costs. The brushless motor is assembled by engaging the first locking block and the second locking block into the first locking slot and the second locking slot, and then tightening the bolts. Correspondingly, by unscrewing the bolts and rotating the upper and lower covers in the opposite direction by five to eight degrees, the brushless motor can be opened for internal inspection. This facilitates disassembly and maintenance, making it convenient and quick for staff to inspect the internal components of the brushless motor as needed, thus improving its practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 The present invention provides the following technical solution: a brushless motor that is easy to disassemble and repair, including a housing 1, a lower end cover 2 provided on one side of the bottom of the housing 1, an upper end cover 3 provided on one side of the top of the housing 1, a bolt 10 provided on one side of the surface of the upper end cover 3, and one end of the bolt 10 passing through the interior of the upper end cover 3 and being threadedly connected to the interior of one side of the housing 1, a first snap-fit groove 11 provided on one side of the surface of the housing 1, a second snap-fit groove 13 provided on the other side of the surface of the housing 1, a first snap-fit block 14 fixedly connected to one side of the surface of the lower end cover 2, and the surface of the first snap-fit block 14 being movably connected to the surface of the first snap-fit groove 11, and a second snap-fit block 16 fixedly connected to one side of the surface of the upper end cover 3, and the surface of the second snap-fit block 16 being movably connected to the surface of the second snap-fit groove 13.
[0023] In this embodiment, multiple sets of corresponding heat dissipation vents 12 can improve the heat dissipation efficiency of the brushless motor, avoid the brushless motor from continuously generating heat during long-term operation, and prevent the internal heat from accumulating and burning out the electronic components inside the brushless motor due to continuous heat accumulation, thereby improving the service life of the electronic components inside the brushless motor.
[0024] In this embodiment, the upper cover 3 and the outer shell 1 are connected by the second snap-fit block 16 and the second snap-fit groove 13. The snap-fit connection method can facilitate the disassembly and maintenance of the brushless motor by the staff, simplify the operation process and save manpower.
[0025] In this embodiment: After the upper cover 3 and the outer shell 1 are snapped together, the brushless motor can be assembled by screwing on the bolt 10, which improves the stability during assembly. The bolt 10 can also restrict the position of the upper cover 3 and the outer shell 1 during the fixing process, avoiding the instability of a single snap-fit. The three sets of corresponding bolts 10 can also further improve the stability of the connection.
[0026] In this embodiment, the handle 15 allows workers to easily twist the lower end cover 2, saving manpower and improving the efficiency of disassembly, assembly, and maintenance.
[0027] In this embodiment, the corresponding positional relationship between the first snap-fit block 14 and the second snap-fit block 16 can prevent incorrect assembly direction, improve production efficiency and consistency, and the three sets of corresponding first snap-fit blocks 14 and second snap-fit blocks 16 can evenly distribute the load, resist external torque, and prevent the structure from deforming due to uneven force. The corresponding positional design simplifies the installation process. During operation, only the three sets of snap-fit blocks need to be aligned in sequence to complete the assembly, reducing the cost of manual adjustment.
[0028] In this embodiment, the three sets of corresponding first snap-fit slots 11 and second snap-fit slots 13 correspond one-to-one with the first snap-fit block 14 and the second snap-fit block 16, making the fixing structure more three-dimensional. The dispersed small snap-fit blocks can reduce the amount of material used, reduce the overall weight of the brushless motor, and maintain the overall strength.
[0029] The working principle and usage process of this utility model are as follows: After the utility model is installed, unscrew the three sets of bolts 10, and then turn the lower end cover 2 by the handle 15 to separate the lower end cover 2 from the outer shell 1. Then, pull out the output shaft 6 and the rotating shaft 4, and then open the upper end cover 3 to inspect the components inside the outer shell 1. After the inspection is completed, align the first snap-fit block 14 with the first snap-fit groove 11, and then turn the lower end cover 2 in the opposite direction to snap the lower end cover 2 to the bottom of the outer shell 1. Then, install the output shaft 6 and the rotating shaft 4 into the bearing mounting part 7. Next, align the second snap-fit block 16 with the second snap-fit groove 13, and then turn the upper end cover 3 in the opposite direction to snap the upper end cover to the top of the outer shell 1. Finally, tighten the bolts 10 to complete the disassembly and maintenance.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
