In view of this, as shown in fig. 1, 2 and 3, the embodiment of the utility model provides a swing mechanism 100, wherein the swing mechanism 100 is applied to a steering column 220 of a mobile carrier 200, the steering column 220 comprises a column 221 and a grip 222, the column 221 is connected with a vehicle body 210 of the mobile carrier 200, and the swing mechanism 100 is connected with the column 221 and the grip 222.

Meanwhile, the swing mechanism 100 is further provided with a limiting mechanism 130 and a detecting member 140 fixed in the housing 110, wherein the limiting mechanism 130 is configured to provide a preset resistance for limiting the swing of the swing member 120, and the detecting member 140 is configured to detect a swing direction of the swing member 120 after overcoming the preset resistance and output a direction signal to a controller (not shown) of the mobile carrier 200.

The mobile carrier 200 may be a carrier or a cart such as a camping car, a small trailer, or a baby carriage, and the embodiment of the present utility model will be described by taking the mobile carrier 200 as a camping car.

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without collision.

As shown in fig. 1, 2 and 3, the swing mechanism 100 provided by the present utility model is applied to a steering column 220 of a moving carrier 200 and is connected to a column 221 and a grip 222 of the steering column 220, the swing mechanism 100 includes a housing 110, a swing member 120, a limiting mechanism 130 and a detecting member 140, the housing 110 is connected to the column 221, the swing member 120 is located in the housing 110 and partially protrudes out of the housing 110, the swing member 120 protruding out of the housing 110 is connected to the grip 222, so that one end of the swing mechanism 100 can be connected to the column 221, and the other end is connected to the grip 222. The swinging member 120 can swing back and forth around the first direction relative to the housing 110. At least a portion of the limiting mechanism 130 is disposed in the housing 110 and abuts against an end of the swinging member 120 away from the grip 222, and the limiting mechanism 130 is configured to provide a preset resistance for limiting the swinging of the swinging member 120. The detecting member 140 is fixed in the housing 110, and the detecting member 140 is configured to detect a swing direction of the swing member 120 after overcoming a preset resistance and output a direction signal.

It can be appreciated that, in the swing mechanism 100 of the present utility model, by providing the housing 110, the swing member 120, the limiting mechanism 130 and the detecting member 140, the housing 110 is connected to the rod 221, the swing member 120 is located in the housing 110 and partially protrudes out of the housing 110 to be connected to the handle 222, and the swing member 120 can swing back and forth around the first direction relative to the housing 110. At least a portion of the limiting mechanism 130 is located in the housing 110 and abuts against an end of the swinging member 120 away from the grip 222, and provides a preset resistance for limiting the swinging of the swinging member 120, so that a user needs to apply a force greater than the preset resistance to the swinging member 120 to enable the swinging member 120 to leave the initial position and swing. The detecting member 140 is fixed in the housing 110, and the detecting member 140 is configured to detect a swing direction of the swing member 120 after overcoming a preset resistance and output a direction signal.

In this way, when controlling the steering of the mobile carrier 200, the user needs to apply a force greater than the preset resistance to the swinging member 120 through the grip 222 to overcome the swing restriction of the limiting mechanism 130 to the swinging member 120, so that the swinging member 120 swings back and forth around the first direction, for example, the swinging member 120 swings from the initial position to the direction away from the initial position, so that the detecting member 140 detects the swinging direction of the swinging member 120. If the force applied by the user is insufficient to overcome the restriction of the limiting mechanism 130 to the swing member 120, the swing member 120 does not leave the initial position and swing, and the detecting member 140 does not detect the swing direction of the swing member 120. In this way, the swing member 120 is prevented from being erroneously touched by the detecting member 140, so that the detecting member 140 can accurately detect a steering signal intended by a user.

As shown in fig. 3, in some embodiments, the limiting mechanism 130 includes a movable member 131, where the movable member 131 is configured to abut against the swinging member 120 and limit the swinging of the swinging member 120, so as to reduce the probability that the swinging member 120 swings from the initial position due to a false touch. When the force driving the swinging member 120 to swing is greater than the preset resistance, the swinging member 120 swings and drives the movable member 131 to rotate, and when the force driving the swinging member 120 is weakened to be less than the preset resistance, the movable member 131 is configured to drive the swinging member 120 to restore to the original position.

In the present utility model, the initial position is a position where the swing member 120 is restricted from swinging by the movable member 131, when a force greater than a preset resistance is applied to the swing member 120, the swing member 120 swings from the initial position in a direction away from the initial position around the first direction and drives the movable member 131 to rotate in the swinging direction, and at this time, the detecting member 140 detects the swinging direction in which the swing member 120 swings away from the initial position and outputs a direction signal to the controller of the moving carrier 200. After that, when the force applied to the swing member 120 is gradually reduced to be smaller than the preset resistance or even the force applied to the swing member 120 is removed, the movable member 131 may be rotated in a direction approaching the initial position and drive the swing member 120 to return to the initial position.

As shown in fig. 3 and 4, in some embodiments, a first groove 150 is formed at an end of the swing member 120 away from the grip 222, and a portion of the movable member 131 extends into the first groove 150 and abuts against a groove wall of the first groove 150, so that stability of connection between the movable member 131 and the swing member 120 can be improved, and stability of the movable member 131 abutting against the swing member 120 can also be improved. When the force driving the swing member 120 to swing is greater than the preset resistance, the wall of the first groove 150 drives the movable member 131 to rotate along the swing direction. When the force of driving the swing member 120 is reduced to be smaller than the preset resistance, the movable member 131 abuts against the wall of the first groove 150 and pushes the swing member 120 to swing back.

As shown in fig. 4, in one embodiment, the first groove 150 includes a bottom wall (not labeled) and two first side walls 151 symmetrically disposed at two sides of the bottom wall along the swinging direction of the swinging member 120, where the movable member 141 abuts against the bottom wall, and the bottom wall of the groove can drive the movable member 131 to turn over when the swinging member 120 swings, and can push the swinging member 120 to swing back by pushing the bottom wall of the groove when the movable member 131 turns over back. The two first side walls 151 extend obliquely from the swing member 120 toward the movable member 131 with a gradually increasing distance therebetween, facilitating assembly and removal of the movable member 131.

As shown in fig. 3 and 4, in some embodiments, the limiting mechanism 130 further includes an abutment mechanism 132, where the abutment mechanism 132 is configured to drive the movable member 131 against the swinging member 120, so as to ensure that the movable member 131 always abuts against the swinging member 120. When the swing member 120 drives the movable member 131 to rotate, the movable member 131 presses against the abutment mechanism 132, and when the force for driving the swing member 120 is reduced to be smaller than the preset resistance, the abutment mechanism 132 is configured to drive the movable member 131 to rotate to the original position. In the present utility model, the abutting mechanism 132 drives the movable member 131 to abut against the swinging member 120, so that the swinging of the swinging member 120 can be more stably restricted, when the swinging member 120 is driven to overcome the preset resistance and swing from the initial position, the swinging member 120 drives the movable member 131 to rotate along the swinging direction, and meanwhile, the movable member 131 presses against the abutting mechanism 132 in the rotating process, so that when the acting force applied to the swinging member 120 is weakened to be smaller than the preset resistance and even the acting force applied to the swinging member 120 is removed, the abutting mechanism 132 can have a reaction force on the movable member 131, and the movable member 131 is driven to rotate and the swinging member 120 is driven to return to the initial position.

As shown in fig. 4, 9 and 10, and in combination with fig. 11, in some embodiments, the propping mechanism 132 includes a propping member 1321 and an elastic member 1322, one end of the elastic member 1322 is connected to the rod 221, the other end of the elastic member 1322 is connected to the propping member 1321, and the propping member 1321 is configured to drive the movable member 131 to prop against the swinging member 120 under the action of the elastic member 1322 so as to limit the swinging of the swinging member 120. When the force driving the swing member 120 to swing is greater than the preset resistance, the movable member 131 rotates and pushes the supporting member 1321 to compress the elastic member 1322, and when the force driving the swing member 120 is weakened to be less than the preset resistance, the elastic member 1322 stretches and pushes the supporting member 1321 to drive the movable member 131 to rotate. Illustratively, the elastic member 1322 is a spring.

As shown in fig. 3 and 11, in some embodiments, a second groove 160 is formed at an end of the supporting member 1321 opposite to the elastic member 1322, and a portion of the movable member 131 extends into the second groove 160 and abuts against the second groove 160, and at least one of two opposite groove walls of the second groove 160 is configured to abut against and limit the movable member 131 when the movable member 131 is driven by the movable member 120 to rotate in the swinging direction of the movable member 120, so as to limit the rotation range of the movable member 131, thereby limiting the swinging amplitude of the movable member 120.

As shown in fig. 3, 4 and 11, in one embodiment, two opposite groove walls of the second groove 160 extend obliquely from the elastic member 1322 toward the movable member 131 with a gradually increasing distance therebetween, so as to facilitate assembly and removal of the movable member 131. In combination with the arrangement of the first groove 150, the first groove 150 and the second groove 160 can limit the movable member 131 to be assembled in the area surrounded by the first groove 150 and the second groove 160, so that the assembling stability of the movable member 131 is improved, and the movable member 131 is not separated from the first groove 150 and the second groove 160 in the process of being driven to rotate by the swinging member 120 and the process of being driven to rotate by the elastic member 1322.

As shown in fig. 9, 10 and 11, in some embodiments, a portion of the abutment mechanism 132 is fixed to the rod 221, and another portion of the abutment mechanism 132 extends into the housing 110 and is fixed to the housing 110 to connect the housing 110 and the rod 221, respectively. In one embodiment, the propping mechanism 132 further includes a fixing element 1323, where the fixing element 1323 is fixed to the rod 221 and extends into the housing 110 partially, the part of the fixing element 1323 extending into the housing 110 is further fixed to the housing 110, and the part of the housing 110 is further fixedly sleeved on the outer peripheral surface of a part of the rod 221, so as to strengthen the connection among the propping mechanism 132, the housing 110 and the rod 221. In the length extending direction of the rod 221, the fixing member 1323 has a cavity 1324 opened toward the swinging member 120, so as to facilitate installation of the elastic member 1322 and the holding member 1321 in the holding mechanism 132. The elastic member 1322 is connected to the cavity 1324, and the supporting member 1321 is slidably connected to the cavity 1324, so that when the swinging member 120 drives the movable member 131 to rotate, the movable member 131 pushes the supporting member 1321 to slide on the cavity 1324 and compress the elastic member 1322, and when the force applied to the swinging member 120 is weakened or removed, the elastic member 1322 stretches to push the supporting member 1321 to slide on the cavity 1324.

As shown in fig. 1 and 4, in some embodiments, the detecting member 140 includes a pressing lever 141 and a triggering portion 142, when the swing member 120 swings against a preset resistance, the pressing lever 141 is pressed by the swing member 120 and presses the triggering portion 142, and the triggering portion 142 is configured to output a direction signal to the controller of the moving carrier 200 when it is detected that it is pressed by the pressing lever 141. Illustratively, the triggering portion 142 is a sensor.

As shown in fig. 5, 6 and 7, and in combination with fig. 8, in one embodiment, one end of the pressing lever 141 abuts against the swing member 120, and the other end is rotatably connected to the trigger 142, so that the pressing lever 141 is pushed against the trigger 142 to press the trigger 142 when the swing member 120 swings in the swing direction from the initial position. Illustratively, the plunger 141 includes a connecting end 1411, a body portion 1412, and a free end 1413 connected in series, the connecting end 1411 being connected to the trigger portion 142, the body portion 1412 extending obliquely from the connecting end 1411 toward the free end 1413 in a gradual trend away from the trigger portion 142. The free end 1413 is spaced from the trigger portion 142, and the free end 1413 is bent from the body portion 1412 toward the side of the oscillating member 120 in a direction opposite to the oscillating member 120, so that the oscillating member 120 abuts against the free end 1413 in the oscillating direction during oscillation. The trigger portion 142 is provided with a sensing contact 1421 on a side facing the pressing rod 141, and when a preset resistance is overcome, the swinging member 120 swings against the free end 1413 toward the trigger portion 142 to press the body portion 1412 against the sensing contact 1421, and at this time, the trigger portion 142 receives a steering operation and sends a steering signal to the controller of the mobile carrier 200.

As shown in fig. 8, in some embodiments, the detecting members 140 include two detecting members 140 spaced apart along the swing direction of the swing member 120 and located at opposite sides of the swing member 120, respectively. In this way, the swinging member 120 can swing from the initial position toward either one of both sides of the swinging member 120, and the two detecting members 140 each detect one swinging direction and each output a direction signal when the corresponding swinging direction is detected.

As shown in fig. 4, 5 and 6, in one embodiment, the swing mechanism 100 further includes a rotating shaft 170, and a local portion of the swing member 120 between two ends is hinged to the housing 110 through the rotating shaft 170, and a central axis of the rotating shaft 170 is in a first direction.

In the present utility model, taking the vertical placement of the swinging member 120 as an example, the two detecting members 140 are respectively on the left and right sides of the swinging member 120, and the swinging member 120 can swing left or right. In the present utility model, the swinging direction of the swinging member 120 is taken as an example of swinging leftwards, and the portion of the swinging member 120 protruding from the housing 110 is fixed to the grip 222, and illustratively, a screw hole 121 is provided at the portion of the swinging member 120 protruding from the housing 110 for mounting a screw fixed to the grip 222. The user holds the grip 222 to apply a force greater than a preset resistance to the swing member 120 and drives the end of the swing member 120 connected to the grip 222 to move to the right, so that the end of the swing member 120 limited to swing by the limiting mechanism 130 swings to the left from the initial position. More specifically, the end of the swing member 120 abutting against the movable member 131 swings left and drives the movable member 131 to rotate left, and at the same time, the abutting member 1321 is pushed to move down to compress the elastic member 1322. At this time, the lever 141 of the left detecting member 140 is pushed against the trigger 142 by the swinging member 120, and the trigger 142 on the left transmits a signal to the controller of the mobile carrier 200 in the direction of turning left. When the force applied to the swing member 120 is removed or weakened, the elastic member 1322 is elastically stretched to push the abutment member 1321 back to the original position, and the movable member 131 is pivoted to the right, so that the swing member 120 is finally returned to the initial position and returns to the initial state.

The movable member 131 is an exemplary movable block, and when the swinging member 120 is driven to swing and drive the movable block to rotate, the movable block turns left or right with the left and right edges facing the elastic member 1322 and in the first direction as fulcrums.

As shown in fig. 6 and 11, in one embodiment, the swing mechanism 100 further includes a first spacer 180 and a second spacer 190, and both the first spacer 180 and the second spacer 190 are penetrated by the rotation shaft 170. In the first direction, the first spacer 180 and the second spacer 190 are respectively located at opposite sides of the swing member 120 to reduce a gap between the hinge portion of the swing member 120 and the housing 110, and make the swing member 120 not easy to tilt toward the housing 110 in the first direction during the swing process, thereby improving the swing stability of the swing member 120.

As shown in fig. 4 and 11, in one embodiment, in the first direction, at least one of two opposite sides of the swing member 120 extends with a protrusion 122, each protrusion 122 is correspondingly connected to a supporting portion 111 disposed in the housing 110, and each supporting portion 111 is correspondingly provided with a receiving slot (not shown) for receiving at least part of the protrusion 122. In the present utility model, the provision of the protruding portion 122 and the receiving groove can reduce the gap between the swing member and the housing 110, improving the swing stability of the swing member 120. Illustratively, the swing member 120 extends beyond the boss 122 on opposite sides in the first direction.

As shown in fig. 1, 2 and 3, the mobile carrier 200 provided in the embodiment of the present utility model includes a controller, a vehicle body 210, a driving component, a steering rod 220 and the swing mechanism 100, where the controller and the driving component are both installed on the vehicle body 210, the controller is respectively connected with the detecting element 140 and the driving component in a communication manner, and the controller is used for controlling the driving component to drive the vehicle body 210 to turn when receiving a direction signal.

The present utility model provides a mobile carrier 200, in which the swing mechanism 100 is used, and the swing mechanism 100 is connected to the rod 221 and the grip 222 of the steering rod 220, and the rod 221 of the steering rod 220 is connected to the vehicle body 210. And the controller and the driving part are both installed on the vehicle body 210, the controller is respectively in communication connection with the detecting element 140 and the driving part, and the controller is used for controlling the driving part to drive the vehicle body 210 to turn when receiving the direction signal. Thus, when the controller is required to control the steering of the vehicle body 210, the swing member 120 can overcome the preset resistance by applying a force greater than the preset resistance to the grip 222, so that the swing member 120 can swing back and forth around the first direction. The detecting element 140 detects the swing direction of the swing element 120 after overcoming the preset resistance and outputs a direction signal, and the controller can drive the vehicle body 210 to turn by controlling the driving component to adjust the turning of the mobile carrier 200 when receiving the direction signal. If the force applied by the user is insufficient to overcome the restriction of the swing member 120 by the stopper mechanism 130, the swing member 120 does not swing, and the detecting member 140 does not detect the movement of the swing member 120. The swinging member 120 can be triggered to swing only when the swinging member 120 is provided with a force with enough magnitude, so that the false touch of the sensor can be effectively prevented, and the steering accuracy of the mobile carrier 200 is improved.

The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the specification and drawings of the present utility model or direct/indirect application in other related technical fields are included in the scope of the present utility model.
