Description

Technical Field

[0001] The utility model relates to the technical field of motors used in air compressor equipment, and in particular to a motor multi-phase electrical wiring switching structure and air compression equipment. Background Art

[0002] Air compressor equipment is applied to automobile air suspension systems, which provide compressed air to the air springs to change the height of the vehicle body, thereby improving the vehicle's passing performance and enhancing the riding experience.

[0003] At present, it is known that air compressor equipment is integrated with a brushless motor and an electronic controller. In order to meet the integration requirements of the air compressor equipment, the control module originally arranged inside the brushless motor is integrated into the external electronic controller, which requires the multi-phase electrical wiring of the brushless motor to be transferred to the electronic controller. The traditional method is to extend the length of the multi-phase electrical wiring and pass it through multiple components until it is connected to the electronic controller. This wiring method is troublesome during assembly, and the wiring is easily confused and takes up space. Excessively long wiring also increases the wiring cost; gaps are easily formed where the wiring passes through the components, allowing external moisture or dust to enter the interior of the motor, affecting the performance of the motor.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1 to 4 As shown, the first aspect of the utility model provides a motor multi-phase electrical wiring adapter structure, including a motor housing 150 , an adapter plate 140 and an electronic controller 120 .

[0029] The motor housing 150 has a notch 200. Usually, the motor housing 150 is a columnar housing with a certain wall thickness, and its material includes aluminum or hard rubber or other materials selected by the manufacturer. The motor housing 150 is provided with a rotor and a stator to realize the conversion of electrical energy into mechanical energy.

[0030] The adapter plate 140 is disposed in the motor housing 150 , and the adapter plate 140 is electrically connected to the motor wiring in the motor housing 150 . A plug 170 is arranged at the slot 200 , and the plug 170 is electrically connected to the adapter plate 140 .

[0031] The adapter board 140 in this embodiment is a printed circuit board, such as Figure 1 As shown, the three-phase wiring 130 of the coil in the motor housing 150 can be fixed to the adapter plate 140 by welding, and electrically connected to the conductive metal wire, and three plugs 170 are connected by the conductive metal wire. It should be noted that the manufacturer can reasonably arrange the number of plugs 170 according to the actual working requirements of the motor, for example, it can be one, two, or more, etc., and is not limited to the number given in this application.

[0032] The electronic controller 120 is integrated with a control program, and is electrically connected to a transfer part, which is installed at the slot 200 and plugged with the plug 170 to achieve electrical connection between the plug 170 and the electronic controller 120. This makes the connection between the electronic controller 120 integrated with the control program and the motor wiring more convenient, more convenient to assemble, and saves space;

[0033] The plug 170 is arranged at the slot 200 of the motor housing 150, so that the plug-in distance between the adapter and the plug 170 is shortened, which saves the wiring distance and avoids messy wiring. Therefore, the above technical solution is superior to the existing wiring method in terms of the difficulty of assembly and cost.

[0034] Typically, the electronic controller 120 is disposed in the electric control box 110 , and the electric control box 110 is fixedly mounted relative to the motor housing 150 .

[0035] In the embodiment of the utility model, the adapter is configured to seal the slot 200 when installed at the slot 200. This is because after the adapter and the slot 200 are assembled, there may be a gap at the assembly site for moisture or dust to pass through, which may affect the working performance of the motor, so it can be selected to seal it through a glue filling process after assembly.

[0036] In the embodiment disclosed in the present utility model, the adapter portion includes an adapter terminal 160, which is a metal column with conductive properties, one end of which is plugged into the plug 170, and the other end is electrically connected to the electronic controller 120. It should be noted that the number of adapter terminals 160 corresponds to the number of plugs 170.

[0037] In some disclosed embodiments of the present invention, a pin 167 connected to the electronic controller 120 is provided at one end of the adapter terminal 160 facing the electronic controller 120. When connected, the two can be reinforced by welding.

[0038] In some embodiments, a slot 190 is provided in the axial direction at the end of the adapter terminal 160 that is plugged into the plug 170. When the adapter terminal 160 and the plug 170 are plugged into each other, the plug 170 is inserted into the slot 190, and the outer surface of the plug 170 is squeezed by the slot 190 so that the plug 170 is clamped in the slot 190. The plug 170 is clamped and fixed by the slot 190 and is not easy to loosen. There is no need to weld and reinforce the connection between the two again, which simplifies the process.

[0039] Exemplarily, a protrusion 191 is formed on the inner wall surface of the slot 190 , and when the adapter terminal 160 is plugged into the plug 170 , the protrusion 191 exerts a squeezing force on the outer surface of the plug 170 .

[0040] It should be noted that the construction of the protrusion 191 includes but is not limited to the following methods: arranged only on one side of the inner wall surface of the slot 190, and the arrangement quantity is set with reference to the actual need for how much clamping force can be provided; arranged oppositely on both sides of the inner wall surface of the slot 190, and the arrangement quantity is set with reference to the actual need for how much clamping force can be provided. When arranged on both sides of the inner wall surface of the slot 190, it can be an opposite arrangement or a staggered arrangement.

[0041] Preferably, the outer contour surface of the protrusion 191 is arc-shaped. The arc-shaped outer contour surface can reduce the friction during insertion, provide guidance, and make the plug 170 easier to insert.

[0042] In the embodiment disclosed in the present utility model, the adapter part also includes a terminal insert 180, and the terminal insert 180 has a through hole 210 adapted to the adapter terminal 160. When the adapter terminal 160 passes through the through hole 210, the adapter terminal 160 located in the through hole 210 is sealed and matched with the through hole 210.

[0043] In some embodiments, the outer wall of the adapter terminal 160 is provided with two sealing grooves 165 spaced apart along the axial direction, and a sealing rubber ring 166 is installed in the two sealing grooves 165 . The adapter terminal 160 is sealed with the through hole 210 through the sealing rubber ring 166 .

[0044] In the embodiment of the utility model, the terminal insert 180 can be installed in the slot 200 of the motor housing 150 to achieve a sealed fit between the terminal insert 180 and the slot 200. Through the sealed fit between the terminal insert 180 and the slot 200, it is possible to prevent a gap for air or water to pass through the slot 200 during assembly to a certain extent. It should be noted that when the terminal insert 180 is used to seal the slot 200, a glue filling process can also be used to fill the slot 200 with glue again to seal it.

[0045] For example, the terminal insert 180 is provided with a crimping portion 181 on the outside, and the motor housing 150 is provided with an installation positioning portion 220 for positioning and installing the crimping portion 181 on the outside of the notch 200. The installation positioning portion 220 cooperates with the crimping portion 181 to facilitate the positioning and installation between the terminal insert 180 and the notch 200, and to assist in ensuring the consistency of the transfer terminal 160 and the plug 170 during plug-in assembly. For example, the installation positioning portion 220 and the crimping portion 181 can be fixed by screws (not shown in the figure).

[0046] Exemplarily, a sealing groove 221 is formed on one end surface of the installation positioning portion 220 facing the crimping portion 181 , and a sealing rubber ring 230 installed in the sealing groove 221 is used to seal between the crimping portion 181 and the installation positioning portion 220 .

[0047] Of course, according to actual conditions, the terminal insert 180 and the notch 200 may also be sealed in other forms and are not limited to the above embodiments.

[0048] In the above embodiment, the transfer terminal 160 is a copper metal column and is integrally formed. The copper material has good electrical conductivity and the integrally formed structure has guaranteed structural strength.

[0049] In the above embodiment, the plug 170 is also made of copper material, which makes the electrical conductivity better when the two are plugged in.

[0050] In addition, the utility model further provides an air compression device 100, including the above-mentioned motor multi-phase electrical wiring adapter structure, which also has the above-mentioned technical effects and will not be described in detail here.

[0051] In summary, the motor multi-phase electrical wiring adapter structure adopted by the utility model includes a motor housing, an adapter plate and an electronic controller integrated with a control program. The coil wiring in the motor housing is switched through the adapter plate and a plug is arranged. The electronic controller is connected to the adapter part, and the adapter part passes through the notch of the motor housing and is plugged together with the plug, which simplifies the connection method between the electronic controller and the motor wiring, makes assembly more convenient and saves space; the plug is arranged at the notch of the motor housing, so that the plug-in distance between the adapter part and the plug is shortened, which in turn saves the wiring distance and avoids messy wiring. Therefore, the above technical solution is superior to the existing wiring method in terms of the difficulty of assembly and cost; similarly, an air compression device provided by the utility model includes the above technical solution structure and also has the above-mentioned advantages;

[0052] At the same time, the adapter terminal of the adapter part of the utility model is sealed with the terminal insert, and the adapter part is sealed with the notch part connected thereto, so as to prevent moisture, dust, etc. from entering the interior of the motor through the adapter part, thereby ensuring the performance of the motor.

[0053] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
