Among them, the speed reduction motor is installed at the first end of the length of the door guide rail. The speed reduction motor includes a motor body and a reduction gearbox fixed integrally along the motor axis, and the motor body is close to the end face of the first end of the length of the door guide rail. The door guide rail includes a lower guide rail body and an upper transmission area. The speed reduction motor is installed in the transmission area. Due to the installation space limitation of the door guide rail and the requirement of reducing the height dimension of the door guide rail itself, it is necessary to minimize the installation space of the speed reduction motor within a limited area.

Content of the Utility Model

[0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an installation structure of a speed reduction motor for an automatic switch induction door, so as to solve the problem of minimizing the installation space of the speed reduction motor when installing the speed reduction motor on the door guide rail.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme: An installation structure of a speed reduction motor for an automatic switch induction door, the speed reduction motor is installed at the first end of the length of the door guide rail. The speed reduction motor includes a motor body and a reduction gearbox fixed integrally along the motor axis, and the motor body is close to the end face of the first end of the length of the door guide rail. The reduction gearbox includes an input gear and a reduction gear meshing with the input gear. The reduction gear is installed on a driving output shaft. Both the input gear and the reduction gear are bevel gears. The axis of the input gear is perpendicular to the driving output shaft and there is an offset distance between the axis of the input gear and the axis of the driving output shaft. There is an included angle θ between the motor axis of the speed reduction motor and the installation axis, and 1° ≤ θ ≤ 5°.

[0005] Preferably, the input gear is integrally connected with a gear shaft, and the gear shaft is connected with the motor shaft of the motor body.

[0006] Preferably, the speed reduction motor is respectively connected with a first mounting bracket and a second mounting bracket at both ends of the motor axis.

[0007] Preferably, the first mounting bracket is a Z-shaped structure, including a first section, a second section and an intermediate section connecting the first section and the second section. The first section is fixed to the door guide rail, and the second section is connected with the motor body.

[0008] Preferably, the motor body is provided with a boss protruding toward the first side and parallel to the second section. The second section is fixed to the boss by bolts, and a shock-absorbing washer is provided between the second section and the boss.

[0009] Preferably, the second mounting bracket is an L-shaped structure, including a first side and a second side. The first side is fixed to the door guide rail, and the second side is connected to the speed reducer.

[0010] Preferably, the speed reducer is provided with a convex column protruding toward the second side. The second side is fixed to the convex column by bolts, and a shock-absorbing washer is provided between the second side and the convex column.

[0011] Preferably, the convex column is provided with a guide hole. One end of the bolt is movably matched with the guide hole, and the other end passes through the second side and is connected with a nut.

[0012] Preferably, the shock-absorbing washer is in an I-shaped configuration.

[0013] Preferably, at least two pulleys are connected to the upper end of the automatic switch induction door. The pulleys are slidably matched with the door guide rail. A transmission pulley is installed on the driving output shaft of the reduction motor. A driven pulley is installed at the end of the second end of the length of the door guide rail. The transmission pulley and the driven pulley are connected by a transmission belt, and the transmission belt is connected to one of the pulleys.

[0014] With the above technical solution of the present utility model, since both the input gear and the reduction gear are bevel gears, the axis of the input gear is perpendicular to the driving output shaft and there is an offset distance between the axis of the input gear and the axis of the driving output shaft. If the motor axis is installed parallel to the installation axis conventionally, it will cause the motor body and the speed reducer to occupy a large space in the height direction. In order to compress this space, an included angle θ is designed between the motor axis and the installation axis, and 1° ≤ θ ≤ 5°. In this way, the total height of the reduction motor can be reduced to maximize the space utilization rate.

[0015] If the included angle is too small, it is difficult to achieve the purpose of reducing the total height of the reduction motor. However, if the included angle is too large, it will instead increase the reduction of the total height of the reduction motor. Therefore, in combination with the offset distance between the axis of the input gear and the axis of the driving output shaft, the included angle θ is usually about 3°.

[0016] The reduction motor is respectively connected with a first mounting bracket and a second mounting bracket at both ends of the motor axis, thereby reliably fixing the reduction motor. In addition, shock-absorbing washers are provided between the first mounting bracket and the second mounting bracket and the reduction motor, which can reduce the vibration during the operation of the reduction motor and reduce the noise when the automatic switch induction door opens and closes.

[0017] These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and drawings.

However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0027] Those skilled in the art can understand that, without conflict, the features in the following embodiments and embodiments can be combined with each other.

[0028] The terms used in the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. For example, the terms indicating orientation or positional relationship such as "upper", "lower", "inner", "outer", etc. are only based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0029] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may include the first and second features being in direct contact, or may also include the first and second features not being in direct contact but being in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0030] In the present utility model, unless otherwise clearly defined and limited, terms such as "mounted", "connected", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] In addition, terms such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0032] Refer to Figures 1 to 6As shown in the figure, this embodiment provides an installation structure 1 for a speed reduction motor of an automatic switch induction door, including a speed reduction motor 11, which is installed at the first end of the length of the door guide rail 2. The speed reduction motor 11 includes a motor body 111 and a speed reduction box 112 that are fixed together along the motor axis A, and the motor body is close to the end face of the first end of the length of the door guide rail. The door guide rail 2 includes a lower guide rail body 21 and an upper transmission area 22. At least two pulleys 25 are connected to the upper end of the automatic switch induction door 3, and the pulleys 25 are slidably matched with the guide rail body 21 of the door guide rail. The speed reduction box 112 includes an input gear 1122 and a reduction gear 1123 that meshes with the input gear 1122, and the reduction gear 1123 is installed on the driving output shaft 1124. Moreover, the reduction gears 1123 that mesh with the input gear 1122 are all bevel gears, and the axis of the input gear 1122 is perpendicular to the driving output shaft 1124.

[0033] As Figure 5 shown, there is an offset distance L between the axis of the input gear (coaxial with the motor axis) and the axis of the driving output shaft.

[0034] Due to the existence of the offset distance L, if the motor axis A is installed parallel to the installation axis B, it will cause the motor body and the speed reduction box to occupy a large space in the height direction, and this height is H1. In order to compress this space, there is an angle θ between the motor axis and the installation axis, and 1° ≤ θ ≤ 5°. In this way, the total height of the speed reduction motor can be reduced, and this height is H2, H2 < H1, so as to maximize the space utilization rate.

[0035] It can be understood that if the angle is too small, it is difficult to achieve the purpose of reducing the total height of the speed reduction motor, but if the angle is too large, it will instead increase the reduction of the total height of the speed reduction motor. Therefore, combined with the size of the offset distance between the axis of the input gear and the axis of the driving output shaft, usually the angle θ is about 3°, that is, the motor axis of the speed reduction motor has an angle of about 3 degrees with the installation axis.

[0036] Furthermore, a transmission pulley 12 is installed on the driving output shaft 1124 of the speed reduction motor, a driven pulley 23 is installed at the second end of the length of the door guide rail, the transmission pulley 12 and the driven pulley 23 are connected by a transmission belt 24, and the transmission belt 24 is connected to one of the pulleys 25, and can be specifically fixed by bolts. Among them, the speed reduction motor 11 and the driven pulley 23 are installed on both sides of the length of the transmission area 22. Referring to the opening principle of the automatic switch induction door in the prior art, when someone needs to enter the door, it is sensed by the sensor, and the electronic control gives the control information to the speed reduction motor. The speed reduction motor drives the transmission belt to drive the pulley on the door to run along the door guide rail to complete the opening action.

[0037] In this embodiment, a first mounting bracket 13 and a second mounting bracket 14 are respectively connected to both ends of the motor axis of the reduction motor 11. The first mounting bracket 13 is a Z-shaped structure, including a first section 131, a second section 132, and an intermediate section 133 connecting the first section and the second section. The first section 131 is fixed to the door guide rail 2, and the second section 132 is connected to the motor body 111. The motor body 111 is provided with a boss 1111 protruding toward the first side and parallel to the second section. The second section 132 is fixed to the boss 1111 by bolts, and a shock-absorbing washer 15 is provided between the second section 132 and the boss 1111. The second mounting bracket 14 is an L-shaped structure, including a first side 141 and a second side 142. The first side 141 is fixed to the door guide rail 2, and the second side 142 is connected to the reduction gearbox 112. The reduction gearbox 112 is provided with a convex column 1121 protruding toward the second side. The second side 142 is fixed to the convex column 1121 by a bolt 16, and a shock-absorbing washer 15 is provided between the second side 142 and the convex column 1121. Specifically, the convex column 1121 is provided with a guide hole, one end of the bolt 16 is movably fitted with the guide hole, and the other end passes through the second side 142 and is connected with a nut.

[0038] Preferably, the shock-absorbing washer 15 is in an I-shaped structure, with a hollow cylinder in the middle and convex rings at both ends, and the bolt passes through the shock-absorbing washer. Therefore, both ends of the shock-absorbing washer have a relatively large contact surface area, and the middle cylinder can provide relatively large elastic support, so the shock-absorbing effect is good. In addition, the door guide rail is made of aluminum alloy or stainless steel profiles.

[0039] As described above, it is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
