Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 2, the door pump 1 of the present invention includes a rotary cylinder 11, and a motor 12, a speed reducing mechanism 13 and a spline shaft 14 disposed in the rotary cylinder 11. And an upper end seat 19 and a lower end seat 18 which are in running fit with the rotary drum 11 are arranged at two ends of the rotary drum 11. The spline shaft 14 is matched with a spline groove arranged on the inner wall of the rotary drum 11, and the motor 12 is in transmission connection with the spline shaft 14 through the speed reducing mechanism 13, so as to drive the rotary drum 11 to rotate.

When the door pump is in use, the upper end seat 19 and the lower end seat 18 are connected with the frame 3. The door pump is provided with a motor 12 in a rotary barrel 11, and the rotary barrel 11 is driven to rotate by the motor 12, and the rotary barrel 11 can be used as a door shaft 5 of a vehicle door 2 for installing a bent arm 6 (see figure 5) when in use. After adopting this door pump 1, door 2 can be directly by the drive of a rotatory section of thick bamboo 11, realize the push-and-pull action, adopted the link mechanism 4 between motor 12 and the door 2 behind the door pump 1 promptly, and motor 12 has also set up in a rotatory section of thick bamboo 11 (door-hinge), so, make whole push-and-pull door structure compacter, the structure is simpler, thereby reduced whole push-and-pull door structure to the occuping of automobile body space, the automobile body can load space bigger, and then has promoted product competitiveness.

Specifically, as shown in fig. 3, the reduction mechanism 13 includes a carrier 131, a ring gear 132, and planet gears 133. The planet carrier 131 is fixedly connected with the lower end base 18 through an output shaft 134, the planet wheel 133 is installed on the planet carrier 131, the gear ring 132 is connected with the outer ring of a bearing 135 sleeved on the output shaft 134 through a screw 137 and is installed on the planet carrier 131, the planet wheel 133 is arranged in the gear ring 132 and is meshed and matched with the gear ring 132, the gear ring 132 is in transmission connection with the spline shaft 14, and the output shaft of the motor 12 is arranged at the center of the planet wheel 133 and is in transmission connection with the planet wheel 133 as a sun. In the figure, the gear ring 132 and the spline shaft 14 are fixedly connected through screws, and the two can also be of an integral structure, namely, a spline is arranged on the outer surface of the gear ring 132. In use, the motor 12 drives the gear ring 132 to rotate through the planet gear 133, and the gear ring 132 drives the rotary drum 11 to rotate through the spline shaft 14. Compared with the common gear speed reducing mechanism, the speed reducing mechanism has a more compact structure, and can reduce the diameter of the rotary cylinder 11, so that the volume of the door pump 1 is smaller. In the figure, the carrier 131 is further provided with a two-stage planetary reduction mechanism, thereby constituting a 3-stage reduction mechanism. Of course, the speed reducing mechanism 13 may also be a single stage, specifically, the speed is selected according to the actual requirement.

When the motor 12 stops rotating, the door 2 may generate impact force to the frame 3 through the end seat due to inertia, which may cause the frame 3 to deform. In order to prevent the frame from being deformed, as shown in fig. 4, the lower end base 18 includes a mounting base 181, a cushion collar 182, and a cushion spring 183 having one end connected to the mounting base 181. The buffer shaft sleeve 182 is rotatably mounted on the mounting seat 181, and one end of the buffer shaft sleeve is rotatably matched with the rotary drum 11, and the planet carrier 131 is fixedly connected with the buffer shaft sleeve 182 through the output shaft 134 fixedly connected with the planet carrier. The two cushion springs 183 are provided, the other ends of the cushion springs 183 are in contact with both sides of the cushion collar 182, and the cushion springs 183 are in eccentric contact with both sides of the cushion collar 182. The buffer shaft sleeve 182 can be directly and rotatably engaged with the rotary drum 11, in the figure, the end of the rotary drum 11 is fixedly provided with the copper sleeve 111, and one end (upper end) of the buffer shaft sleeve 182 is rotatably engaged with the rotary drum 11 through the copper sleeve 111. It is understood that a thrust bearing 17 is required between the buffer shaft sleeve 182 and the rotary cylinder 11 (copper sleeve 111) to reduce the friction therebetween. The buffer spring 183 is eccentrically abutted against both sides of the buffer shaft housing 182, that is, a connecting line between the buffer springs 183 does not pass through the center of the buffer shaft housing 182. When the motor 12 stops rotating (when the lock is locked), the inertia force of the vehicle door 2 is transmitted to the buffer shaft sleeve 182 through the output shaft 134, so that the buffer shaft sleeve 182 rotates, the buffer springs 183 on the two sides are compressed, the purposes of buffering and absorbing shock and preventing the vehicle frame from deforming are achieved, and thus, the requirement on the strength of the vehicle frame can be reduced. Even if the motor 12 is locked, the vehicle door 2 is pushed by a certain force, and the vehicle door 2 can drive the planet carrier 131 to rotate by compressing the buffer spring 183, so that the vehicle door can be opened emergently.

The damping sleeve 182 may be rotatably mounted on the mounting 181 by way of a rotatable fit with an axle on the mounting 181. In fig. 4, a round pin 185 is fixedly installed on the mounting seat 181, the other end (lower end) of the buffering shaft sleeve 182 is engaged with the round top of the pin 185, and a gap 186 is left between the other end (lower end) of the buffering shaft sleeve 182 and the mounting seat 181 to facilitate the shaking of the buffering shaft sleeve 182. The upper end seat 19 is internally provided with a joint bearing 191 which is rotationally matched with the rotary cylinder 11. The knuckle bearing 191 is directly rotatably engaged with the rotary drum 11, and the knuckle bearing 191 is rotatably engaged with the rotary drum 11 through a support spline shaft 192. The structure can lead the vehicle door 2 to swing up and down in a certain range in the using process, thereby being convenient for the installation of the vehicle door 2 and reducing the size requirement on the vehicle frame 3.

One end of the buffer spring 183 may be directly fixed to the mounting seat 181, in fig. 4, the mounting seat 181 is provided with a sliding groove 187 extending along the axis of the buffer shaft sleeve 182, and one end of the buffer spring 183 is connected to a sliding seat 184 provided on the sliding groove 187. This prevents the buffer spring 183 from being bent and deformed during the swing of the buffer shaft housing 182.

The motor 12 can be braked electrically (only the high-speed end of the motor can be braked by an electromagnetic brake), in fig. 2, an electromagnetic brake 15 is arranged in the rotary cylinder 11, and the electromagnetic brake 15 is connected with an output shaft of the motor 12. Namely, the utility model discloses a mechanical braking, braking effect is better.

In order to facilitate the installation of the electromagnetic brake 15, the motor 12 of the door pump is a two-shaft motor. So that the electromagnetic brake 15 can be connected to the other output shaft of the electric machine.

A speed detector 16 which is convenient for controlling the motion of the vehicle door 2 is also arranged in the rotary cylinder 11, and the speed detector 16 is connected with an output shaft of the motor 12.

As shown in fig. 5, the present application further provides an electric out-swinging translation door structure, which includes a door 2, a curved arm 6 and a door pump 1 adopting the above structure, wherein an upper end seat 19 and a lower end seat 18 are installed on the frame 3, and the door 2 is fixedly connected with the rotary cylinder 11 through the curved arm 6. The electric outward swinging translation door adopting the structure saves the link mechanism 4 between the motor 12 and the door 2, and the motor 12 is also arranged in the rotating cylinder 11 (door spindle), so that the whole sliding door structure is more compact and simpler in structure, the occupation of the whole sliding door structure to the vehicle body space is reduced, the vehicle body loading space is larger, and the product competitiveness is further improved.
