[0044] Before describing the anti - rollover device according to the embodiments of the present utility model, the application scenarios of the anti - rollover device will be described. The anti - rollover device can be used for vehicles that are prone to rollover, such as rickshaws, electric vehicles, or fuel vehicles, for example, two - wheeled vehicles, three - wheeled vehicles, four - wheeled vehicles, etc. The usage environment of the anti - rollover device is not limited. In the following embodiments, the anti - rollover device applied to a three - wheeled vehicle will be taken as an example for description.

[0045] Embodiments of the present utility model refer to Figure 1 and Figure 2 As shown, a kind of anti - rollover device is provided, which includes a first frame body 100, a second frame body 200, a driving component 300, and a wheel body 500.

[0046] The first frame body 100 is used to connect to the vehicle body 700 so that the anti - rollover device is installed on the vehicle body 700 of the three - wheeled vehicle.

[0047] One end of the second frame body 200 is rotatably connected to the first frame body 100, and the other end of the second frame body 200 is rotatably connected to the wheel body 500. The second frame body 200 can rotate relative to the first frame body 100, so that the second frame body 200 switches between a folded position and an open position. The second frame body 200 is parallel to the first frame body 100 or the second frame body 200 forms a first included angle relative to the first frame body 100, which is called the second frame body 200 being in the folded position; the second frame body 200 opens a second included angle α relative to the first frame body 100, which is called the second frame body 200 being in the open position, and the second included angle α is greater than the first included angle. In the open position, the wheel body 500 is used to support the ground and play a supporting role. When the anti - rollover device is installed on the three - wheeled vehicle, the wheel body 500 provides auxiliary support and can prevent the three - wheeled vehicle from rolling over. In the folded position, the distance from the wheel body 500 to the ground is greater than the distance from the wheel body 500 to the ground in the open position. When the wheel body 500 does not need to support the ground, the second frame body 200 is kept in the folded position to avoid the wheel body 500 contacting with stones, protrusions, etc. on the ground and affecting the stability of the three - wheeled vehicle.

[0048] Among them, the first included angle can be 0° ± 20°, and the first included angle is as close to 0° as possible, which helps to reduce the volume of the anti - rollover device; the second included angle α is greater than 90°, which helps to ensure the stability of the second frame body 200. Referring to Figure 2 As shown, the first included angle can be 0°, and the first included angle is not marked in the figure; referring to Figure 1 and Figure 6 As shown, the second included angle α is 120°.

[0049] The driving component 300 is connected between the first frame body 100 and the second frame body 200. The driving component 300 is used to drive the second frame body 200 to switch from the folded position to the open position. The driving component 300 provides rotational power to the second frame body 200 so that the second frame body 200 rotates relative to the first frame body 100. The driving component 300 can drive the second frame body 200 to switch from the folded position to the open position. In some cases, the driving component 300 can also drive the second frame body 200 to switch from the open position to the folded position. Or, the user manually drives the second frame body 200 to switch from the open position to the folded position.

[0050] In some embodiments, referring to Figure 3 As shown, the driving component 300 includes a torsion spring 310. The first frame body 100 and the second frame body 200 are rotatably connected through a rotating shaft 210. The torsion spring 310 is sleeved on the rotating shaft 210, and the torsion arms of the torsion spring 310 respectively abut against the first frame body 100 and the second frame body 200. In the folded position, the torsion spring 310 is in an elastically deformed state, and the elastic acting force of the torsion spring 310 causes the second frame body 200 to switch from the folded position to the open position. During the process of the second frame body 200 switching from the open position to the folded position, the torsion spring 310 undergoes elastic deformation. Figure 3 Schematically, the torsion spring 310 includes a first torsion arm 311 and a second torsion arm 312. The first torsion arm 311 abuts against the first frame body 100, and the second torsion arm 312 abuts against the second frame body 200. Among them, the rotating shaft 210 can be a part of the first frame body 100 or the second frame body 200, or the rotating shaft 210 can be an independent part independent of the first frame body 100 and the second frame body 200. The installation method of the rotating shaft 210 is not limited. Referring to Figure 3 As shown, the rotating shaft 210 is an independent part. One of the first frame body 100 and the second frame body 200 is fixedly connected to the rotating shaft 210, and the other is rotatably connected to the rotating shaft 210.

[0051] In some cases, the driving component 300 can include a motor (not schematically shown in the figure). The output shaft of the motor is connected to the second frame body 200 and is used to drive the second frame body 200 to rotate relative to the first frame body 100. At this time, the second angle of the second frame body 200 can be controlled by the rotation angle of the motor.

[0052] Referring to Figure 1 and Figure 2As shown, a stop portion 220 is provided at one end of the second frame body 200. In the open position, the stop portion 220 abuts against and is limited by the first frame body 100 to prevent the second frame body 200 from further rotating relative to the first frame body 100. When the driving component 300 includes a torsion spring 310, the second frame body 200 is held at the open position of the second angle by the stop portion 220, ensuring the support stability of the second frame body 200 for the wheel body 500. When the driving component 300 includes a motor, the rotation angle of the second frame body 200 can also be limited by the stop portion 220, improving the support stability of the second frame body 200 in the open position.

[0053] Reference Figure 4 and Figure 5 As shown, the anti-overturning device further includes a locking component 400. The locking component 400 is connected between the first frame body 100 and the second frame body 200. The second frame body 200 is held at the folded position by the locking component 400, ensuring the stability of the second frame body 200 in the folded position. When the wheel body 500 needs to provide support, the locking component 400 releases the locking of the second frame body 200, and the driving component 300 can drive the second frame body 200 to switch to the open position, and the wheel body 500 supports the ground, playing an auxiliary support role; when the wheel body 500 does not need to provide support, the locking component 400 keeps the second frame body 200 at the folded position, and the distance from the wheel body 500 to the ground increases, avoiding interference between the wheel body 500 and the second frame body 200 with the ground, and ensuring the stable travel of the tricycle.

[0054] In some embodiments, the locking component 400 includes a driving member 410 and a locking assembly 420. In the folded position, the locking assembly 420 locks the second frame body 200, and the driving member 410 is used to drive the locking assembly 420 to move so that the locking assembly 420 releases the locking of the second frame body 200, enabling the second frame body 200 to switch from the folded position to the open position.

[0055] The driving member 410 can provide a moving driving force or a rotational driving force, and the form of the driving force provided by the driving member 410 is not limited. Correspondingly, the locking assembly 420 can release the locking of the second frame body 200 through linear motion or rotational motion. The cooperation mode between the driving member 410 and the locking assembly 420 is diverse and is not limited here.

[0056] When the driving member 410 can provide a moving driving force, the driving member 410 includes a linear driver, and the linear driver can be an electromagnetic lock 411, a cylinder, a linear motor, or other devices that can provide linear power, which is not limited here and can be specifically selected according to needs.

[0057] The linear driver includes an electromagnetic lock 411 and a moving block 412 connected to the output end of the electromagnetic lock 411. The moving block 412 is connected to a locking assembly 420. The electromagnetic lock 411 is used to drive the moving block 412 to move, so as to drive the locking assembly 420 to release the locking of the second frame body 200, and the structure is simple.

[0058] In some embodiments, referring to Figure 5 and Figure 6 As shown, the locking assembly 420 includes a first locking member 421 and a second locking member 422. A first part 4212 of the first locking member 421 is rotatably connected to the first frame body 100. A second part 4213 of the first locking member 421 is connected to the second locking member 422. The first locking member 421 is connected to a driving member 410. The second locking member 422 locks the second frame body 200. In the folded position, the second locking member 422 locks the second frame body 200. The driving member 410 is used to drive the first locking member 421 to move, so that the first locking member 421 drives the second locking member 422 to move and releases the locking of the second locking member 422 on the second frame body 200. The first locking member 421 and the second locking member 422 cooperate to realize the locking and unlocking of the second frame body 200, and the structure is simple.

[0059] When the driving member 410 provides a rotational driving force, the driving member 410 can be connected to the first part 4212 to drive the first locking member 421 to rotate relative to the first frame body 100. When the driving member 410 provides a translational driving force, the position where the driving member 410 is connected to the first locking member 421 does not need to be at the first part 4212, so as to convert the translational power of the driving member 410 into the rotational movement of the first locking member 421 relative to the first frame body 100.

[0060] In some embodiments, the first locking member 421 and the second locking member 422 are connected by an elastic member 423. The first locking member 421 and the second locking member 422 are elastically connected, and the connection flexibility between the first locking member 421 and the second locking member 422 is stronger. The elastic member 423 can be a device with elastic telescopic functions such as a spring or a rubber band.

[0061] In some embodiments, the first locking member 421 is provided with a first limiting portion 4211, and the second locking member 422 is provided with a second limiting portion 4221. Referring to Figure 5 As shown, in the folded position, the second limiting portion 4221 and the first limiting portion 4211 are mutually limited. The second limiting portion 4221 can prevent the first limiting portion 4211 from rotating in the first direction, and the second frame body 200 is kept in the folded position by the first locking member 421 and the second locking member 422. Referring to Figure 6As shown, in the open position, the first limiting portion 4211 and the second limiting portion 4221 are disengaged from each other, so that the second frame body 200 can be switched to the open position under the driving force of the driving component 300. From the open position to the folded position, the second locking member 422 is driven by the second frame body 200 to rotate relative to the first frame body 100 in the second direction, so that the second limiting portion 4221 and the first limiting portion 4211 are mutually limited, and then the second locking member 422 locks the second frame body 200. Wherein, the first direction is the opposite direction of the second direction.

[0062] Reference Figure 5 As shown, the second frame body 200 is provided with a locking block 230, and the second locking member 422 is provided with a locking hook 4222. In the folded position, the locking block 230 is limited in the hook groove 4223 of the locking hook 4222. From the folded position to the open position, the locking block 230 disengages from the hook groove 4223 from the opening of the locking hook 4222, and the locking block 230 and the locking hook 4222 are unlocked. The cooperation mode between the locking hook 4222 and the locking block 230 is simple and has good structural stability.

[0063] When the driving member 410 includes an electromagnetic lock 411 and a moving block 412, the linear motion power of the moving block 412 drives the first locking member 421 to rotate relative to the first frame body 100, and then drives the second locking member 422 to rotate relative to the first frame body 100 through the elastic member 423, so as to realize the switching from the folded position to the open position, Figure 5 switching from the folded position shown Figure 6 to the open position shown. When the second frame body 200 switches from the open position to the folded position, Figure 6 switching from the state shown Figure 5 to the state shown, the locking block 230 of the second frame body 200 drives the second locking member 422 to rotate relative to the first frame body 100 until the locking block 230 enters the hook groove 4223 through the opening of the locking hook 4222. At the same time, the second limiting portion 4221 of the second locking member 422 contacts the first limiting portion 4211 of the first locking member 421, and the second limiting portion 4221 moves from below the first limiting portion 4211 to above the first limiting portion 4211, and the first limiting portion 4211 and the second limiting portion 4221 are limited to lock the second frame body 200 in the folded position.

[0064] In some embodiments, reference Figure 1 、 Figure 2 and Figure 7As shown, the anti-rollover device further includes a protective member 600 fixed to the first frame 100. At least one of the first locking member 421 and the second locking member 422 is rotatably connected to the protective member 600. Both the first locking member 421 and the second locking member 422 are located between the first frame 100 and the protective member 600. The protective member 600 is provided with a notch 610. In the folded position, the locking block 230 is limited to the protective member 600 through the notch 610. In the opened position, the locking block 230 is disengaged from the limit of the protective member 600. The cooperation between the protective member 600 and the first frame 100 can protect the first locking member 421 and the second locking member 422, preventing the first locking member 421 and the second locking member 422 from being interfered by the external environment. The structure is simple and helps to improve the stability of the locking component 400.

[0065] In some other cases, different from the above-mentioned locking component 400, the locking component 400 can be a locking shaft. In the folded position, the locking shaft passes through the first frame 100 and the second frame 200 to keep the second frame 200 in the folded position. The second frame 200 can be switched to the opened position through the driving component 300 and its own gravity. The structure is simple and the operation is convenient.

[0066] In some cases, the user can manually control the action of the locking component 400 to release the locking effect of the locking component 400 on the second frame 200, and the second frame 200 is switched from the folded position to the opened position. When the user senses a risk of rollover of the tricycle, the user can manually control the action of the locking component 400, such as pressing the anti-rollover button, pulling the anti-rollover starter, etc., to drive the locking component 400 to act by the driving member 410. Or, the state of the tricycle can also be identified by an automatic recognition device. If it is determined that there is a risk of rollover of the tricycle, then the locking component 400 is controlled to act, so that the locking component 400 can automatically release the locking effect on the second frame 200, and the second frame 200 is switched from the folded position to the opened position. Automatically identifying the state of the tricycle can simplify the operation of the user and has a higher degree of automation. The above-mentioned electromagnetic lock 411 can be communicatively connected to the automatic recognition device. When the automatic recognition device recognizes that there is a risk of rollover of the tricycle, the electromagnetic lock 411 receives an action instruction, and the linear motion power of the electromagnetic lock 411 drives the first locking member 421 to rotate relative to the first frame 100.

[0067] In some embodiments, the first frame 100 includes a first mounting member 110 and a second mounting member 120. The first mounting member 110 is for mounting on the vehicle body 700, and the second mounting member 120 is rotatably connected to the other end of the second frame 200. At least one of the first mounting member 110 and the second mounting member 120 is provided with a long hole 121, and the first mounting member 110 and the second mounting member 120 are connected by a fastener passing through the long hole 121. The relative positions of the first mounting member 110 and the second mounting member 120 can be adjusted by adjusting the position of the fastener within the long hole 121.

[0068] Referring Figures 1 to 3 As shown, the first mounting member 110 is a strip-shaped plate member. The first mounting member 110 is provided with a circular hole, and the second mounting member 120 is provided with a long hole 121. The fastener passes through the long hole 121 and the circular hole and is fixed to the vehicle body 700. The second mounting member 120 includes a top plate 122, a first bent plate 123 and a second bent plate 124. The top plate 122 is provided with a long hole 121. Both the first bent plate 123 and the second bent plate 124 are bent downward from the top plate 122. The first bent plate 123 and the second bent plate 124 are located on opposite sides of the top plate 122, and the first bent plate 123 and the second bent plate 124 are rotatably connected to the second frame 200. When the second frame 200 is in the folded position, the second frame 200 is located between the first bent plate 123 and the second bent plate 124, and the first bent plate 123 and the second bent plate 124 can play a role in protecting the second frame 200.

[0069] When the second frame 200 is provided with a locking block 230, the second bent plate 124 is provided with a recess. The side wall of the recess plays a role in limiting the locking block 230. The locking block 230 enters and exits the recess through the opening of the recess, which can not only ensure the protective effect of the second bent plate 124 on the second frame 200, but also ensure that the second frame 200 accurately returns to the folded position.

[0070] For the embodiments of the present utility model, referring Figures 8 to 11 As shown, a tricycle is further provided, which includes a vehicle body 700 and an anti-rollover device as described in any one of the above. Referring Figure 8 and Figure 9 As shown, the vehicle body 700 includes a front wheel 710 and a rear wheel 720. The first frame 100 is located between the front wheel 710 and the rear wheel 720. Since the anti-rollover device has the above beneficial effects, the tricycle having the above anti-rollover device has the above beneficial effects. For details, reference can be made to the above content, which will not be elaborated here.

[0071] In Figure 8 when the second frame 200 of the anti-rollover device is in the open position, the wheel body 500 of the anti-rollover device can play a role in auxiliary support. The front wheel 710, the wheel body 500 of the anti-rollover device and a rear wheel 720 form a triangular support, reducing the risk of rollover.Figure 9 In this case, the second frame body 200 of the rollover prevention device is in the folded position, the wheel body 500 is retracted, and the front wheel 710 and the two rear wheels 720 of the tricycle form a triangular support.

[0072] Reference Figure 8 and Figure 9 As shown in the figure, the rollover prevention device is installed at a position on the chassis of the vehicle body 700 close to the front wheel 710, which helps the front wheel 710, the rollover prevention device and a rear wheel 720 to form a triangular support.

[0073] Reference Figure 10 As shown in the figure, the rear wheels 720 of the tricycle include a left rear wheel and a right rear wheel. When the right rear wheel is lifted, there is a risk of the tricycle tipping to the left. At this time, the rollover prevention device on the left side of the vehicle body 700, the left rear wheel and the front wheel 710 form a triangular support. Reference Figure 11 As shown in the figure, the tricycle is in a stable traveling state, the front wheel 710 and the two rear wheels 720 of the tricycle form a triangular support, and the second frame body 200 of the rollover prevention device is in the folded position.

[0074] In some embodiments, the vehicle body 700 includes a rollover detection member 730. The rollover detection member 730 is communicatively connected to the locking member 400. Based on the rollover angle of the vehicle body 700 detected by the rollover detection member 730 reaching a preset angle, the movement of the locking member 400 is controlled to release the limit on the second frame body 200. The preset angle can be 10°, 20°, etc., and can be set as needed.

[0075] The rollover detection member 730 may include, but is not limited to, a gyroscope, a Hall sensor, an angle sensor, a radar, etc.

[0076] When the tricycle turns while riding, due to excessive speed, under the action of the centrifugal force of the vehicle, one of the rear wheels 720 will leave the ground. When it leaves the ground, the processor receives the tilt angle of the vehicle body 700 detected by the rollover detection member 730 (for example, a gyroscope or a Hall sensor). When it is determined that the tilt angle reaches the preset angle, the processor communicates with the electromagnetic lock 411. When the electromagnetic lock 411 receives the control signal, the locking of the second frame body 200 is released, and the second frame body 200 opens the second included angle relative to the first frame body 100, so that the wheel body 500 of the rollover prevention device can support on the ground. The front wheel 710, the wheel body 500 of the rollover prevention device and a rear wheel 720 form a stable triangle, thereby preventing personal injury caused by the tricycle tipping over and falling to the ground.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent substitutions of the technical solutions of the present utility model do not depart from the spirit and scope of the technical solutions of the present utility model and should all be covered within the scope of the claims of the present utility model.
