Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile accessories, in particular to a gear box transition sleeve for automobile window motor. BACKGROUND

[0002] In the field of automobile window motor, the existing window motor is mainly composed of a stator, a rotor and a box body. Among them, the box body has a space reserved inside for assembling the transition sleeve, and the rotor is assembled with the ball bearing in the transition sleeve. When the motor is in working condition, a pair of magnetic shoes in the stator will generate a magnetic field, which drives the rotor to rotate, thereby realizing the lifting function of the window.

[0003] In order to ensure that the rotor remains stable during rotation and does not appear to be inclined, it is particularly important to install the transition sleeve structure inside the box body. This structure can provide good support and positioning for the rotor, thereby making the motor performance more stable and reliable.

[0004] However, the existing transition sleeve structure has many problems in actual application. The common design method at present is to directly assemble the transition sleeve in the box body. This simple assembly method has obvious defects. On the one hand, the transition sleeve is difficult to be fixed well, and when the motor is running for a long time, it is subject to external forces such as vibration and impact, the transition sleeve has the risk of falling off and rotating. Once the transition sleeve falls off or rotates, it will not only affect the normal operation of the motor, cause the abnormal lifting of the window, but also cause the wear and damage of the internal parts of the motor, shorten the service life of the motor.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-3 The utility model provides a kind of technical scheme, a kind of gear box transition sleeve for automobile window motor, including gear box 9 and the transition sleeve body 1 rotationally connected in gear box 9, comprising,

[0023] Positioning protrusion 2 is connected at the top of transition sleeve body 1, and the number is at least three;

[0024] equidistant grooves 3 are arranged on the bottom of the transition sleeve body 1, and the number of the equidistant grooves 3 is at least six;

[0025] connecting protrusions 4 are arranged on the bottom of the transition sleeve body 1.

[0026] In the specific implementation, when the automobile window motor is running, a pair of magnetic tiles in the stator generates a magnetic field to drive the rotor to rotate, thereby realizing the lifting action of the vehicle window. The transition sleeve body 1 plays a role of auxiliary support and positioning.

[0027] The positioning protrusions 2 are connected to the top of the transition sleeve body 1, and the number of the positioning protrusions 2 is at least three. When the transition sleeve body 1 is installed into the gear box 9, the positioning protrusions 2 cooperate with the structure at the corresponding position inside the gear box 9, so that the position of the transition sleeve body 1 in the gear box 9 can be quickly and accurately determined, thereby improving the assembly efficiency and accuracy. At the same time, during the operation of the motor, the positioning protrusions 2 and the cooperating structure of the gear box 9 restrict each other, preventing the transition sleeve body 1 from being displaced in the vertical direction, and ensuring that the transition sleeve body 1 is always in a stable working position, thereby providing a stable support basis for the rotor.

[0028] The number of the equidistant grooves 3 arranged on the bottom of the transition sleeve body 1 is at least six. These equidistant grooves 3 can be used as force points during assembly, which facilitates the positioning, adjustment and fixation of the transition sleeve body 1 by the operator or automatic assembly equipment. At the same time, during the operation of the motor, the equidistant grooves 3 change the stress distribution at the bottom of the transition sleeve body 1, thereby enhancing the connection stability between the transition sleeve body 1 and the bottom of the gear box 9, and further reducing the risk of the transition sleeve body 1 falling off.

[0029] The connecting protrusions 4 on the bottom of the transition sleeve body 1 also play an important role. They tightly cooperate with the grooves or other connecting structures at the bottom of the gear box 9, thereby further increasing the resistance to rotation of the transition sleeve body 1, and effectively preventing the transition sleeve body 1 from rotating together with the rotor.

[0030] Referring to Figure 2 , the gear box 9 is rotatably connected with a driving shaft 8.

[0031] It should be noted that the driving shaft 8 rotatably connected in the gear box 9 is usually connected with the rotor at one end to receive the power transmitted by the rotor.

[0032] In the specific implementation, the driving shaft 8 is arranged to facilitate the rotation of the rotor.

[0033] Referring to Figure 3 , the transition sleeve body 1 is rotatably connected with a mounting pad 5, and the mounting pad 5 is provided with an auxiliary gasket 6 on one side.

[0034] In specific implementation, the mounting pad 5 rotatably connected in the transition sleeve body 1 plays a buffering and adapting role between the driving shaft 8 and the transition sleeve body 1. The driving shaft 8 passes through the hole of the mounting pad 5, and the flexible material of the mounting pad 5 can compensate for the possible slight size deviation and coaxiality error between the driving shaft 8 and the transition sleeve body 1. When the driving shaft 8 rotates, the mounting pad 5 rotates with it, reducing the friction and wear between the two, and also reducing the vibration and noise caused by insufficient manufacturing precision of the components.

[0035] Referring to Figure 3 , the driving shaft 8 is connected with a ball bearing 7, which is rotatably arranged in the transition sleeve body 1.

[0036] In specific implementation, the ball bearing 7 connected to the driving shaft 8 is rotatably arranged in the transition sleeve body 1. The ball bearing 7 as a key connecting piece between the driving shaft 8 and the transition sleeve body 1 greatly reduces the friction resistance between the two. When the rotor drives the driving shaft 8 to rotate, the inner ring of the ball bearing 7 rotates synchronously with the driving shaft 8, while the outer ring is relatively static with the transition sleeve body 1. The balls inside the ball bearing 7 roll between the inner and outer rings, allowing the driving shaft 8 to rotate smoothly in the transition sleeve body 1, reducing energy loss.

[0037] Referring to Figure 3 , the material of the mounting pad 5 is rubber.

[0038] In specific implementation, the material of the mounting pad 5 is rubber, which takes advantage of the corrosion resistance of rubber to extend the service life of the mounting pad 5.

[0039] Referring to Figure 1 , the shape of the positioning protrusion 2 is arc-shaped.

[0040] In specific implementation, the arc-shaped design makes the contact between the positioning protrusion 2 and the gear box 9 be linear or surface contact, which can provide a larger contact area and enhance the stability of positioning compared to other shapes. At the same time, the arc-shaped structure has better guidance, which can guide the transition sleeve body 1 to enter the correct position more smoothly during installation, improving the assembly efficiency.

[0041] Working principle: When the automobile window motor is running, a pair of magnetic shoes in the stator generates a magnetic field, driving the rotor to rotate, and then realizing the lifting action of the vehicle window. The transition sleeve body 1 plays a supporting and positioning role in it.

[0042] The positioning lugs 2 are connected to the top of the transition sleeve body 1 and the number is at least three. When the transition sleeve body 1 is installed in the gear box 9, the positioning lugs 2 cooperate with the structure in the corresponding position inside the gear box 9, which can quickly and accurately determine the position of the transition sleeve body 1 in the gear box 9, and improve the assembly efficiency and accuracy. At the same time, during the operation of the motor, the positioning lugs 2 and the cooperating structure of the gear box 9 restrict each other, preventing the transition sleeve body 1 from shifting in the vertical direction, ensuring that the transition sleeve body 1 is always in a stable working position, providing a stable support foundation for the rotor.

[0043] The equidistant grooves 3 opened at the bottom of the transition sleeve body 1 are at least six in number. These equidistant grooves 3 can be used as force points during assembly, making it easy for operators or automated assembly equipment to position, adjust and fix the transition sleeve body 1. At the same time, during the operation of the motor, the equidistant grooves 3 change the stress distribution at the bottom of the transition sleeve body 1, enhancing the connection stability of the transition sleeve body 1 and the bottom of the gear box 9, and further reducing the risk of the transition sleeve body 1 falling off.

[0044] The connecting lugs 4 at the bottom of the transition sleeve body 1 also play an important role. They tightly cooperate with the grooves or other connecting structures at the bottom of the gear box 9, further increasing the resistance to rotation of the transition sleeve body 1, effectively preventing the transition sleeve body 1 from rotating with the rotor.
