Description

Technical Field

[0001] This utility model belongs to the field of motor controllers, and specifically relates to a motor controller. Background Technology

[0002] With the continuous development of technology, controllers are increasingly widely used in various devices. During the operation of a controller, components such as capacitors, rectifier bridges, and IGBTs generate a large amount of heat. If this heat cannot be dissipated in time, it will seriously affect the controller's performance and lifespan. Meanwhile, controllers used outdoors or in harsh environments are susceptible to intrusion by insects and other foreign objects, leading to fan blockage, short circuits, and other malfunctions. Motors with different parameters (such as different power ratings) require different components in their control circuit design, resulting in different installation requirements for controllers. Existing controller housings typically only accommodate motors with a single parameter. If the parameters are changed, the controller housing needs to be redesigned and remolded, leading to poor versatility and high costs. Furthermore, with the development of IoT technology, enabling remote control upgrades for controllers is crucial for equipment maintenance and functional upgrades. Therefore, designing a controller that can accommodate the installation requirements of motors with multiple parameters, has good compatibility and versatility, efficient heat dissipation, insect protection, and remote control upgrade capabilities is of significant practical importance.

[0003] A search revealed that application number "CN201610281146.7" discloses "a motor controller," which states that "capacitors can be directly mounted on a capacitor board, effectively reducing the length of the capacitor leads and preventing overheating during operation due to excessively long leads. This effectively prevents the capacitor leads from burning out, improving the capacitor's lifespan and the stability of the motor controller." While directly mounting the capacitor on a capacitor board effectively reduces the length of the capacitor leads and prevents overheating during operation, thus effectively preventing capacitor leads from burning out and improving the capacitor's lifespan and the stability of the motor controller, the above-mentioned document still has the following problems in practical use:

[0004] In practical use, the controllers have poor versatility. Existing controller housings are usually only compatible with controllers that can handle motors with a single parameter. If the parameter requirements are changed, the controller housing needs to be redesigned and remolded, increasing costs. They also have poor compatibility for indoor and outdoor installations. For example, to accommodate outdoor installations, the controller's high-heat-generating components are fully sealed, resulting in poor heat dissipation. Outdoor insect prevention is not considered, and foreign objects such as geckos can enter, leading to fan blockage, short circuits, and other malfunctions. They cannot be remotely operated, controlled, or upgraded, resulting in high maintenance costs. Furthermore, the housing cover is prone to coming off easily, which can pull on the wiring and make it difficult to grip.

[0005] Based on this, providing a controller that is highly practical, has good compatibility, good heat dissipation, is insect-proof, can be operated remotely, is not easy to detach or pull on the wires, and is easy to grip. Utility Model Content

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Example 1

[0034] Please see Figure 1-6 A motor controller includes a housing 100, an anti-detachment and anti-tear cable and a gripping component 200, and a waterproof and heat-dissipating reinforcement component 300.

[0035] Please refer to the details. Figure 1 The housing 100 is made of PC and ABS.

[0036] Please see Figure 1 The anti-detachment and anti-pull line and easy-grip component 200 includes grooves 210 formed on both sides of the housing 100. One end of the housing 100 is hinged to a housing cover 240 through a housing support ear 220 and a housing cover support ear 230. A boss edge 250 is provided at the bottom of the rotating shaft of the housing cover support ear 230. The center of the housing support ear 220 is a first waist hole 260. A button plate 270 is embedded in one end of the inner wall of the housing cover 240.

[0037] In one specific embodiment, the provided cover 240 facilitates the following: when the boss stop 250 rotates to a position not 90 degrees from the first waist hole 260, the boss stop 250 is blocked by the housing support ear 220, preventing the cover 240 from detaching. When the boss stop 250 rotates to a 90-degree angle with the first waist hole 260, due to gravity and thrust, the boss stop 250 is blocked by the housing support ear 220, preventing the cover 240 from detaching. Lifting the cover 240 allows the boss stop 250 to be inserted into or removed from the housing support ear 220 and the first waist hole 260, ensuring that the cover 240 will not detach during opening and closing. Furthermore, after opening the cover 240, it can still be connected to the housing 100 via the cover support ear 230 and the housing support ear 220, preventing the cable from being pulled and thus achieving the purpose of preventing detachment and cable pulling. Furthermore, the housing lugs 220 and the cover lugs 230 can be integrally formed with the housing 100 and the cover 240 respectively, eliminating the need for additional hinges, making installation convenient and cost-effective. The grooves 210 facilitate gripping during use and increase the strength of the bottom side, reducing housing deformation.

[0038] Please see Figure 1The waterproof heat dissipation reinforcement component 300 includes a waterproof boss 310 at one end of the housing 100, a circular groove 311 at one end of the cover 240, a first sealing ring 320 embedded inside the circular groove 311, an mounting plate 330 at one end of the inner wall of the housing 100, a first mounting post 340 and a second mounting post 350 at one end of the mounting plate 330, a first circuit board 360 fixedly connected to one end of the first mounting post 340 by a first screw, a second circuit board 370 fixedly connected to one end of the second mounting post 350 by a second screw, a heat sink 380 in the middle of the inner wall of the housing 100, a plurality of fins 390 at one end of the heat sink 380, two fans 3910 at the bottom of the heat sink 380, and a plurality of ventilation openings at the top and bottom of the housing 100.

[0039] In one specific embodiment, the first sealing ring 320 is provided to prevent water from entering the interior of the housing 100 through the contact gap between the housing 100 and the housing 240 when the cover 240 is closed during use. Furthermore, the entire groove 311 is provided on the housing 240, which increases the edge thickness of the housing 240, thereby increasing its strength and reducing deformation of the housing 240 when it presses against the first sealing ring 320, thus achieving reinforcement. Additionally, the mounting plate 330 in the middle of the housing 100 contacts and adheres to the heat sink 380. After the screws are tightened and fixed, the square hole and the protective groove 1600 are both within the mounting surface of the heat sink 380. By applying sealant or installing a sealing ring at the protective groove 1600 to fill the gap between the middle mounting plate 330 of the housing 100 and the heat sink 380, water is prevented from entering the housing 100 through the square hole. A fan 3910 is installed at the end of the heat sink 380. The front and rear ends of the housing 100 are provided with heat dissipation holes, which are aligned with the fan 3910 port and the air duct of the heat sink 380, so that the controller can turn on the fan 3910 to dissipate heat during use, thereby achieving the purpose of waterproofing, heat dissipation and reinforcement.

[0040] Please see Figure 1 The first circuit board 360 has several capacitors 400 at one end, and the mounting plate 330 has several round holes inside, through which the capacitors 400 pass. The top of the mounting plate 330 has a reinforcing rib boss 500.

[0041] In one specific embodiment, the reinforcing rib protrusion 500 facilitates the support and reinforcement of the housing 100 during use, making the housing 100 more stable during use and preventing shaking.

[0042] Please see Figure 1An insulating pad 600 is provided between the first circuit board 360 and the second circuit board 370. A metal stud 700 is inserted and connected inside the insulating pad 600. The two ends of the metal stud 700 are fixedly connected to the first circuit board 360 and the second circuit board 370, respectively.

[0043] In one specific embodiment, the insulating pad 600 facilitates the prevention of interference between the first circuit board 360 and the second circuit board 370 and ensures electrical safety during use. The metal stud 700 facilitates the limiting of the insulating pad 600 to prevent it from moving. The metal stud 700 also serves as a connection and fixation between the two circuit boards and conducts current.

[0044] Please see Figure 2 The second circuit board 370 is provided with a rectifier bridge 800 and a power device 900 at its two ends respectively. One end of the power device 900 passes through the second circuit board 370 and is provided with a substrate 1000. The substrate 1000 is composed of a copper clad layer, an insulating layer and a heat dissipation layer. A square hole is opened in the interior of the mounting plate 330. The rectifier bridge 800 and the substrate 1000 pass through the square hole and are fixedly connected to the heat sink 380.

[0045] In one specific embodiment, the provided substrate 1000 facilitates the use of an insulating layer located between the copper cladding layer and the heat dissipation layer to ensure that the heat sink 380 is not charged during use.

[0046] Please see Figure 3 A temperature sensor 1100 is disposed between the substrate 1000 and the rectifier bridge 800, and one end of the temperature sensor 1100 is fixedly connected to the heat sink 380 by a third screw.

[0047] In one specific embodiment, a temperature sensor 1100 is provided so that during use, the temperature sensor 1100 is close to the heat sink 380 and is linked with the fan 3910. When the temperature sensor 1100 detects that the temperature is higher than the set value, the fan 3910 runs to dissipate heat from the controller.

[0048] Please see Figure 1 The other end of the housing 100 is provided with a back plate 1200, and the back plate 1200 has several second waist holes inside.

[0049] In one specific embodiment, the back plate 1200 allows the back plate 1200 to be adapted to various types of motor mounting holes by utilizing the second waist hole during use. At the same time, the back plate 1200 makes one end of the housing 100 relatively closed, ensuring that when the controller is used outdoors, foreign objects such as geckos are prevented from entering and blocking the fan 3910 or the heat dissipation channel.

[0050] Please see Figure 1 The first mounting post 340 and the second mounting post 350 have a height difference. The keypad 270 and the second circuit board 370 are connected by a ribbon cable for power supply and signal transmission. A third mounting post 1300 is provided at one end of the second circuit board 370, and a third circuit board 1400 is provided at one end of the third mounting post.

[0051] In one specific embodiment, the provided button panel 270 allows users to press buttons to send information to the controller, enabling the controller to control the motor and improving stability.

[0052] Please see Figure 5 A second sealing ring 1500 is provided between the capacitor 400, the first circuit board 360 and the reinforcing rib boss 500, and a protective groove 1600 is provided on the outer wall of the square hole.

[0053] In one specific embodiment, when using fewer capacitors, the detachable insert of the injection mold used to manufacture the housing can be replaced to seal the excess holes during injection molding, so that the housing can be compatible with the installation requirements of motors with different parameters. A second sealing ring 1500 is fitted on the capacitor 400 on the first circuit board. By fixing the first circuit board, the sealing ring is squeezed and deformed between the circuit board and the reinforcing rib boss 500 to achieve sealing at the circular hole of the capacitor, or waterproof sealing is achieved by applying glue to the gap between the circular hole of the intermediate mounting plate and the capacitor.

[0054] In use, the provided cover 240 facilitates the following: when the boss stop 250 rotates to a position not 90 degrees from the first waist hole 260, the boss stop 250 is blocked by the housing lug 220, preventing the cover 240 from being removed. When the boss stop 250 rotates to a 90-degree angle with the first waist hole 260, due to gravity and thrust, the boss stop 250 is blocked by the housing lug 220, preventing the cover 240 from being removed. Lifting the cover 240 allows the boss stop 250 to be inserted into or removed from the housing lug 220 and the first waist hole 260. To ensure that the cover 240 will not detach during opening and closing, and that even after opening, the cover 240 remains connected to the housing 100 via the cover lug 230 and housing lug 220, preventing cable tethering, and that the housing lug 220 and cover lug 230 can be integrally molded with the housing 100 and cover 240 respectively, eliminating the need for additional hinges, simplifying installation, saving costs, and utilizing the groove 210 for easy gripping during use, while also increasing the strength of the bottom side and reducing the weight of the housing. The deformation achieves the purpose of preventing detachment and wire pulling. Then, when the cover 240 is closed during use, the first sealing ring 320 prevents water from entering the interior of the housing 100 through the contact gap between the housing 100 and the cover 240. The entire groove 311 is set on the cover 240, which can increase the edge thickness of the cover 240, thereby increasing the strength and reducing the deformation of the cover 240 when it squeezes the first sealing ring 320, thus achieving reinforcement. Furthermore, the mounting plate 330 in the middle of the housing 100 contacts and fits the screws with the heat sink 380. After tightening and fixing, the square hole and the protective groove 1600 are both located within the mounting surface of the heat sink 380. By applying sealant or installing a sealing ring at the protective groove 1600 to fill the gap between the middle mounting plate 330 of the housing 100 and the heat sink 380, water is prevented from entering the housing 100 through the square hole. A fan 3910 is installed at the end of the heat sink 380. Heat dissipation holes are provided at the front and rear ends of the housing 100, aligned with the fan 3910 port and the air duct of the heat sink 380, so that the fan 3910 can be turned on for heat dissipation during use, thereby achieving the purpose of waterproofing, heat dissipation and reinforcement.

[0055] Example 2

[0056] The difference between this embodiment and Embodiment 1 is as follows:

[0057] Please see Figure 7 Waterproof adhesive 1700 is applied to the gap between the 330 round hole on the mounting plate and the 400 capacitor.

[0058] In one specific embodiment, adhesive is applied to the gap between the 330 circular hole in the intermediate mounting plate and the capacitor to achieve a waterproof seal, which improves the sealing performance, prevents water leakage during use, improves stability, and increases safety.

[0059] 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.
