Description

Technical Field

[0001] This utility model relates to the field of electronic actuator technology, and in particular to an automotive electronic actuator that can save assembly space. Background Technology

[0002] The electric actuator is used to control the raising and lowering of car windows. The electric actuator consists of a mounting base, mounting plate, steel cable, mounting housing, worm gear, worm, and motor. When using the electric actuator, the motor is started by the controller, and the reducer makes the worm rotate, which drives the worm wheel to rotate, causing the steel cable to retract, which in turn drives the slider on the car window to move upward, thereby raising the car window with the cooperation of the guide rail and pulley system.

[0003] The inventors discovered in their daily work that during the assembly of the electronic actuator, because the mounting base is fixed to the car door with bolts, the screw needs to be placed into the mounting groove on the mounting base before the worker places the mounting base into the car door for installation. However, during the process of placing the mounting base into the car door, the screw is easily pushed out of the mounting groove by the components inside the car door. This requires the worker to manually push the screw back into the mounting groove from inside the car door, which may result in a larger assembly space required. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, the mounting base is fixed to the car door with bolts. Before installing the mounting base, the screw needs to be placed into the mounting groove on the mounting base. Then, the worker puts the mounting base into the car door for installation. However, during the process of putting the mounting base into the car door, the screw is easily pushed out of the mounting groove by the components inside the car door. This requires the worker to manually put the screw into the mounting groove again, which may require a large assembly space. Therefore, this utility model proposes an automotive electronic control actuator that can save assembly space.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive electronic control actuator that can save assembly space, comprising a mounting base, a mounting plate, and a steel cable. The lower end of the mounting base is provided with a mounting assembly, and the upper end of the mounting base is provided with a mounting shell and a pre-fixing assembly. The mounting shell contains a worm gear and a worm. A motor is mounted on the left end of the mounting base, the motor controls the rotation of the worm gear, and the worm gear controls the movement of the steel cable. The mounting assembly includes a fixing cover located at the lower end of the mounting base, and a first airbag is mounted on the upper end of the fixing cover. The inner wall of the fixing cover has protrusions.

[0006] The effect achieved by the above components is as follows: by setting the mounting components, when the mounting base is installed inside the car door, the screw is placed into the mounting groove on the mounting base, and then the fixing cover is fastened to the base for fixation, keeping the first airbag in the mounting groove. Then, through the air intake mechanism, the first airbag is made to bulge vertically with the fixing cover in the mounting groove, thereby pushing the screw outward. Then, the mounting base is placed inside the car door, and then the nut is used to fix it to the screw. This achieves the goal of minimizing the need for pre-set assembly space for workers to manually insert and push the bolt.

[0007] Preferably, an air inlet pipe is fixedly connected between the two first airbags, and an air nozzle is fixedly connected to one side of the fixed cover, the air nozzle being fixed to the first airbag.

[0008] The effect achieved by the above components is as follows: when the air nozzle is connected to the air pump and the air pump is started, the multiple first airbags inflate through the air intake pipe.

[0009] Preferably, a magnetic ring is fixedly connected to the inner wall of the mounting base, and a second airbag is installed at the bottom of the inner wall of the fixing cover.

[0010] The effect achieved by the above components is as follows: by setting a magnetic ring, the screw is attracted when the magnetic ring is close to the screw, thus assisting in limiting the screw's position.

[0011] Preferably, a control tube is provided at the lower end of the fixed cover, the control tube is fixed to the second airbag, and the control tube is used to connect an external air pump.

[0012] The effect achieved by the above components is as follows: when it is necessary to remove the fixing cover for installation on other mounting bases, the first airbag is deflated by the air pump and air nozzle, then the air pump is connected to the control pipe and then inflated, causing the second airbag to bulge, thereby separating the fixing cover from the mounting base, then the fixing cover is pulled out, and then it can be installed on other mounting bases.

[0013] Preferably, the pre-fixing component includes a circular ring fixedly connected to the lower end of the mounting shell, the circular ring having a protrusion on its arc surface, and the circular ring being inserted into the mounting base.

[0014] The effect achieved by the above components is as follows: when the mounting shell is installed onto the mounting base, the mounting shell is dragged so that the circular ring is inserted into the mounting base, so that the multiple mounting holes on the mounting shell are aligned with the mounting holes on the mounting base, and then screws are screwed in to fix it.

[0015] Preferably, the inner wall of the mounting base is slidably fitted with an insert block, and the right end of the insert block has a sliding surface.

[0016] The effect achieved by the above components is as follows: when the circular ring is inserted into the mounting base, the insert block is retracted into the mounting base by means of the sliding surface. At the same time, the reset mechanism retracts. When the circular ring is fully inserted into the mounting base, the reset mechanism resets, allowing the insert block to be inserted into the fixed ring, thereby further fixing the circular ring.

[0017] Preferably, a spring is fixedly connected to the left end of the insert block, and the other end of the spring is fixed to the mounting base.

[0018] The effect achieved by the above components is as follows: when the circular ring is inserted into the mounting base, the insert block is retracted into the mounting base by means of the sliding surface, and at the same time the spring contracts. When the circular ring is fully inserted into the mounting base, the spring returns to its original position, allowing the insert block to be inserted into the fixed ring.

[0019] Preferably, a pull rope is fixedly connected to the left end of the insertion block, and the pull rope passes through the mounting base.

[0020] The effect achieved by the above components is: pulling the pull rope causes the insert to retract completely into the mounting base, and then dragging the mounting shell for disassembly.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting an installation component, when installing the mounting base into the car door, the screw is placed into the mounting groove on the mounting base, and then the fixing cover is fastened to the base for fixation, keeping the first airbag in the mounting groove. Then, through the air intake mechanism, the first airbag bulges vertically with the fixing cover in the mounting groove, thereby pushing the screw outward. Then, the mounting base is placed into the car door, and then the nut is used to fix it to the screw. This avoids the need for a pre-set assembly space for workers to manually push the bolt in. It solves the problem that when the mounting base is fixed to the car door with bolts, the screw needs to be placed into the mounting groove on the mounting base before the mounting base is installed. Then, the worker puts the mounting base into the car door for installation. However, during the process of putting the mounting base into the car door, the screw is easily pushed out of the mounting groove by the components inside the car door. This requires the worker to manually push the screw back into the mounting groove, which may require a large assembly space. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an automotive electronic control actuator that can save assembly space includes a mounting base 1, a mounting plate 4, and a steel cable 5. The lower end of the mounting base 1 is provided with a mounting component 2, and the upper end of the mounting base 1 is provided with a mounting shell 6 and a pre-fixing component 3. The mounting shell 6 is provided with a worm gear and a worm. The left end of the mounting base 1 is equipped with a motor 7, which controls the rotation of the worm gear and controls the movement of the steel cable 5.

[0029] The following section will explain the specific settings and functions of installation component 2 and pre-fixed component 3.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the mounting component 2 includes a fixing cover 21 located at the lower end of the mounting base 1, and a first airbag 22 mounted on the upper end of the fixing cover 21. The inner wall of the fixing cover 21 has protrusions. By setting the mounting component 2, when the mounting base 1 is installed into the car door, the screw is placed into the mounting groove on the mounting base 1, and then the fixing cover 21 is fastened to the base for fixation, keeping the first airbag 22 locked in the mounting groove. Then, through the air intake mechanism, the first airbag 22 bulges vertically with the fixing cover 21 in the mounting groove, thereby pushing the screw outwards. Then, the mounting base 1 is placed into the car door, and then a nut is used to fix it to the screw. This minimizes the need for pre-set assembly space for workers to manually insert and push the bolt. An air intake pipe 24 is fixedly connected between the two first airbags 22, and an air nozzle 25 is fixedly connected to one side of the fixing cover 21. The air nozzle 25 and... The first airbag 22 is fixed, and the air nozzle 25 is connected to the air pump. The air pump is started, causing the multiple first airbags 22 to inflate via the air inlet pipe 24. A magnetic ring 23 is fixedly connected to the inner wall of the mounting base 1, and a second airbag 26 is installed at the bottom of the inner wall of the fixing cover 21. By setting the magnetic ring 23, the screw is attracted when the magnetic ring 23 is close to the screw, thus assisting in limiting the screw. A control pipe 27 is set at the lower end of the fixing cover 21. The control pipe 27 is fixed to the second airbag 26 and is used to connect an external air pump. When it is necessary to remove the fixing cover 21 for installation on other mounting bases 1, the first airbags 22 are deflated by the air pump and air nozzle 25. Then, the air pump is connected to the control pipe 27 and inflated, causing the second airbag 26 to inflate, thereby separating the fixing cover 21 from the mounting base 1. Then, the fixing cover 21 is pulled out, and then it can be installed on other mounting bases 1.

[0031] Reference Figure 4As shown in this embodiment: the pre-fixing component 3 includes a circular ring 31 fixedly connected to the lower end of the mounting shell 6. The circular ring 31 has a protrusion on its arc surface. The circular ring 31 is inserted into the mounting base 1. When the mounting shell 6 is installed into the mounting base 1, the mounting shell 6 is dragged so that the circular ring 31 is snapped into the mounting base 1, so that the multiple mounting holes on the mounting shell 6 are aligned with the mounting holes on the mounting base 1. Then, screws are screwed in for fixation. An insert block 32 is slidably inserted into the inner wall of the mounting base 1. The right end of the insert block 32 has a sliding surface 35. When the circular ring 31 is snapped into the mounting base 1, the insert block 32 is retracted into the mounting base 1 by means of the sliding surface 35. At the same time, the reset mechanism retracts, and the circular ring 31 is fully engaged. When inserted into the mounting base 1, the reset mechanism resets, causing the insert 32 to be inserted into the fixing ring, thereby further fixing the circular ring 31. A spring 33 is fixedly connected to the left end of the insert 32, and the other end of the spring 33 is fixed to the mounting base 1. When the circular ring 31 is inserted into the mounting base 1, the insert 32 is retracted into the mounting base 1 by means of the sliding surface 35, and at the same time the spring 33 contracts. When the circular ring 31 is fully inserted into the mounting base 1, the spring 33 resets, causing the insert 32 to be inserted into the fixing ring. A pull rope 34 is fixedly connected to the left end of the insert 32. The pull rope 34 passes through the mounting base 1. Pulling the pull rope 34 causes the insert 32 to be fully retracted into the mounting base 1, and then the mounting shell 6 is dragged for disassembly.

[0032] Working principle:

[0033] When using the electric actuator, the controller starts the motor 7, which in turn drives the worm gear to rotate via the reducer. This causes the steel cable 5 to contract, which in turn moves the slider on the car window upward. This, in conjunction with the guide rail and pulley system, raises the car window. When installing the mounting base 1 into the car door, the screw is placed into the mounting groove on the mounting base 1, and then the fixing cover 21 is fastened to the base for fixation. The first airbag 22 is held in the mounting groove. Then, the air nozzle 25 is connected to the air pump, and the air pump is started. This causes multiple first airbags 22 to inflate via the air intake pipe 24, making them perpendicular to the fixing cover 21 within the mounting groove. This pushes the screw outward. The mounting base 1 is then placed into the car door, and the nut is used to secure it to the screw. This minimizes the need for pre-set assembly space for workers to manually insert and push the bolt. A magnetic ring 23 is used to attract the screw when it approaches, providing auxiliary limit to the screw. When the fixing cover needs to be removed... When mounting 21 is used on other mounting bases 1, the first airbag 22 is deflated by the air pump and air nozzle 25. Then, the air pump is connected to the control pipe 27 and inflated, causing the second airbag 26 to inflate, thereby separating the fixing cover 21 from the mounting base 1. Then, the fixing cover 21 is pulled out, and it can then be installed on other mounting bases 1. When the mounting shell 6 is installed on the mounting base 1, the mounting shell 6 is dragged so that the circular ring 31 is engaged with the mounting base 1, aligning the multiple mounting holes on the mounting shell 6 with the mounting holes on the mounting base 1. Then screw in the screws for fixation. When the circular ring 31 is inserted into the mounting base 1, the insert 32 is retracted into the mounting base 1 by means of the sliding surface 35. At the same time, the spring 33 contracts. When the circular ring 31 is fully inserted into the mounting base 1, the spring 33 returns to its original position, allowing the insert 32 to be inserted into the fixing ring, thereby further fixing the circular ring 31. Pull the pull rope 34 to retract the insert 32 completely into the mounting base 1. Then drag the mounting shell 6 to disassemble. The mounting plate 4 is fixed with a threaded rod for fixing to the car door.
