The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

As shown in fig. 1-2, one aspect of the present application provides a roller brake comprising: brake disc 150, lock car arm 130 and brake piece 140, brake piece 140 swing joint is in brake disc 150, lock car arm 130 connects in brake disc 150 to make lock car arm 130 can drive brake disc 150 to realize the brake to the first direction motion relatively brake piece 140, brake piece 140 is used for cooperating with lock car arm 130 in order to drive lock car arm 130 to the first direction motion.

The preferred application method of the roller brake provided by the embodiment of the present application may include connecting the locking cable 110 to the locking arm 130, connecting the braking cable 120 to the braking member 140, and moving the locking arm 130 in a first direction to drive the brake disc 150 to implement braking, and when the locking arm 130 is moved to a position where the brake disc 150 is in a braking state and the locking arm 130 is fixed at the position, locking is implemented. When the locking operation is performed, the locking arm 130 can move towards the first direction, the braking member 140 does not move along with the locking arm 130, and when the braking operation is performed, the braking member 140 moves and drives the locking arm 130 to move towards the first direction, so that the braking is realized. Specifically, the fact that the locking arm 130 can move in a first direction relative to the braking member 140 means that the braking member 140 can not move together with the locking arm 130 when the locking arm 130 moves in the first direction; the first direction is a moving direction of the locking arm 130 when braking or locking is performed.

According to the roller brake provided by the embodiment of the application, the brake piece 140 is arranged, so that the brake cable 120 can be connected to the brake piece 140, the brake piece 140 can not move together with the locking arm 130 when the locking arm 130 moves to lock the vehicle, and the problem that the brake cable 120 is loosened because the part of the brake cable 120 connected to the locking arm 130 moves together with the locking arm 130 when the vehicle is locked is solved; in addition, if a tensioning structure is adopted which is installed on the brake disc 150 and directly acts with the brake cable 120, when the bicycle is locked, the brake cable 120 is tensioned by the tensioning structure so as to avoid the brake cable 120 from loosening, and in the process of repeatedly locking and unlocking the bicycle, the tensioning structure and the brake cable 120 repeatedly act to easily cause the brake cable 120 to be worn, thereby reducing the service life of the brake cable 120, and through the roller brake provided by the embodiment of the application, by attaching brake cable 120 to brake member 140, brake member 140 can not move with latch arm 130, the problem of the slack of the brake cable 120 caused by the movement of the portion of the brake cable 120 connected to the locker arm 130 along with the locker arm 130 does not occur, and then the tensioning structure is not needed, the abrasion of the brake cable 120 caused by the tensioning structure can be avoided, and the service life of the brake cable 120 is prolonged.

In one embodiment of the present application, brake member 140 is pivotally attached to brake disc 150. This facilitates the installation of the brake 140, thereby improving the production efficiency. Of course, the brake member 140 and the brake disc 150 may be slidably engaged to enable the brake member 140 to move relative to the brake disc 150, for example, a sliding slot slidably engaged with the brake member 140 may be formed on the brake disc 150 to enable the brake member 140 to move linearly or in a curve relative to the brake disc 150, and in addition, as long as the brake member 140 can drive the locking arm 130 to move in the first direction, the brake member 140 and the brake disc 150 may be connected by other connection methods.

In one embodiment of the present application, brake disc 150 has an axis of rotation such that brake member 140 can pivot about the axis of rotation. In the conventional roller brake, when the brake or the lock is performed by the locking arm 130, the locking arm 130 generally rotates around the axis of the brake disc 150, and when the brake piece 140 can pivot around the axis, the brake piece 140 is convenient to drive the locking arm 130 to synchronously move in the same direction when moving, so that the stability of the matching of the brake piece 140 and the locking arm 130 is improved at least to a certain extent, and the braking effect is ensured to a certain extent.

In one embodiment of the present application, the braking members 140 have a slack position and a braking position distributed in a first direction, and the roller brake includes a returning member 160 for biasing the braking members 140 at the slack position. Through this piece 160 that resets, the messenger is in the brake position or can get back to the pine parking stall at the brake position and the somewhere between the position of loosing the car under the effect of this piece 160 that resets on 140, and then makes the vehicle that has adopted the roller brake that this application embodiment provided can normally travel to can make the motion of brake 140 from the position of loosing the car to the brake position once more when carrying out the next brake. The braking position refers to a position of the braking member 140 when the brake disc 150 is in a braking state, that is, when a vehicle using the roller brake cannot move due to braking, and as shown in fig. 2, the release position refers to a position of the braking member 140 when no braking force is obtained.

In one embodiment of the present application, the brake member 140 is mounted to the brake disc 150 by a return member 160. This allows the brake member 140 to be positioned in a slack position by the restoring member 160 when not moving with the latch arm 130, thereby further avoiding a possible slack condition of the brake cable 120.

In one embodiment of the present application, the latch arm 130 is coupled to the brake disc 150 via a reset member 160. After braking, the reset piece 160 can drive the braking piece 140 by driving the locking arm 130, so that the braking piece 140 returns to the loosening position, that is, the resetting of the braking piece 140 is realized. Of course, as shown in fig. 1, at least two resetting pieces 160 may also be adopted, so that the brake piece 140 is connected with the brake disc 150 through at least one resetting piece 160, and the locking arm 130 is connected with the brake disc 150 through at least one resetting piece 160, thereby not only realizing the resetting of the brake piece 140 and the locking arm 130, but also further avoiding the loosening of the brake cable 120.

In one embodiment of the present application, the restoring member 160 is an elastic member. The elastic piece is easy to obtain and install and low in cost, so that the production efficiency is improved, and the cost is reduced. The elastic member used in the embodiment of the present application may be a torsion spring, a tension spring, a pressure spring, a gas spring, a magnetic spring, or the like; in the embodiment of the present application, the returning element 160 may also adopt an electromechanical structure, such as a linear motor, or a hydraulic or pneumatic device, such as an oil cylinder, an air cylinder, or the like, besides an elastic element.

In one embodiment of the present application, a brake cable connecting portion 141 for connecting the brake cable 120 is formed on the brake 140, and a projection of the brake cable connecting portion 141 on a first plane perpendicular to the first direction is separated from a projection of the catcher arm 130 on the first plane. This can prevent, at least to some extent, friction or collision between the locking arm 130 and the brake cable 120 that may occur when the locking arm 130 moves, and particularly when the brake cable 120 and the locking cable 110 extend in a first direction component, the locking arm 130 is driven by the locking cable 110 to easily collide with the brake cable 120, and the projection of the brake cable connecting portion 141 in the first plane is separated from the projection of the locking arm 130 in the first plane, so that collision or friction between the locking arm 130 and the brake cable 120 when the locking arm 130 moves in the first direction is avoided as much as possible.

In one embodiment of the present application, the vehicle locking arm 130 is provided with a space 170 through which the brake cable 120 passes, and a projection of the brake cable connecting portion 141 on the first plane is located on a projection of the space 170 on the first plane. Through the avoiding space 170, friction or collision possibly occurring between the brake cable 120 and the vehicle locking arm 130 can be avoided at least to a certain extent, moreover, the brake cable 120 can penetrate through the vehicle locking arm 130, and then a gap between the vehicle locking arm 130 and the brake cable 120, which is formed outside the brake arm for avoiding the vehicle locking arm 130 from the brake cable 120, is avoided, so that the whole volume of the roller brake is reduced, and the possibility of collision or friction between the roller brake and the outside is reduced.

In one embodiment of the present application, a guide groove for guiding the movement of the brake cable 120 is formed in the brake cable connecting portion 141. The guide groove can prevent the movement of the brake cable 120 from deviating from the movement path at least to a certain extent, so that the movement of the brake piece 140 is relatively stable, and a good braking effect is ensured.

In one embodiment of the present application, brake 140 is configured to abut latch arm 130. This makes the engagement of brake 140 with locking arm 130 simpler, facilitating the manufacture of the roller brake provided by the embodiments of the present application. Besides the above-mentioned abutting, the braking member 140 and the locking arm 130 may have magnetic members, and the engagement between the braking member 140 and the locking arm 130 is realized by the engagement between the two magnetic members, and the connection between the braking member 140 and the locking arm 130 may be realized by a mechanical structure, such as a gear set; when the braking member 140 is engaged with the locking arm 130, it is required to ensure that the locking arm 130 can move towards the first direction to brake or lock the vehicle, but the moving direction of the braking member 140 is not limited, and the moving direction of the braking member 140 may be the same as or different from the moving direction of the locking arm 130, but the movement of the locking arm 130 towards the first direction is realized through a gear set or other mechanical structures, although the moving direction of the braking member 140 is preferably the same as the moving direction of the locking arm 130.

In one embodiment of the present application, the brake 140 is located rearward of the latch arm 130 in the first direction. On the premise that the brake piece 140 can be abutted to the car locking arm 130, the brake piece 140 can be arranged close to the brake disc 150 as much as possible in the axial direction of the brake disc 150, so that the size of the brake piece 140 in the axial direction of the brake disc 150 is reduced in the roller brake provided by the embodiment of the application, the space occupied by the roller brake is reduced, and the possibility of collision or friction between a vehicle adopting the roller brake and the outside is reduced at least to a certain extent. Specifically, when the brake 140 is located behind the latch arm 130, an escape space 170 may be formed on the brake arm for the brake cable 120 to pass through. In addition to positioning the braking member 140 behind the locking arm 130 in the first direction, the braking member 140 may be positioned at a side of the locking arm 130, and an abutting end is formed on the braking member 140, so that the braking member 140 abuts against the locking arm 130 through the abutting end.

In one embodiment of the present application, brake 140 is adapted to engage with latch arm 130. This makes the engagement between the braking member 140 and the locking arm 130 more stable, and at least to some extent, prevents the braking member 140 from moving away from the moving path when the braking member 140 is engaged with the locking arm 130, thereby reducing the possibility of slipping at the abutting portion between the braking member 140 and the locking arm 130. Specifically, a groove structure may be formed at a position where the braking member 140 and the locking arm 130 are engaged, and the groove structure may be located on the braking member 140, the locking arm 130, or both the braking member 140 and the locking arm 130.

In one embodiment of the present application, a limit groove for engaging with the brake member 140 is formed on the locking arm 130 to limit the position of the brake member 140 in the axial direction of the brake disc 150. This limits the possibility that the brake member 140 deviates from the movement path in the axial direction of the brake disc 150 at least to a certain extent, and improves the stability of the movement of the brake member 140, thereby obtaining a better braking effect; specifically, the brake element 140 may have a locking portion extending in an axial direction perpendicular to the brake disc 150, and the limiting groove may have groove walls facing in the axial direction of the brake disc 150, and when the brake element 140 is engaged with the vehicle locking arm 130, the locking portion is locked in the limiting groove, and the locking portion is limited by the groove walls, so that the position of the brake element 140 in the axial direction of the brake disc 150 is limited.

Another aspect of the application provides a brake system, which comprises the roller brake provided by the embodiment of the application.

According to the brake system provided by the embodiment of the application, by adopting the roller brake provided by the embodiment of the application and arranging the brake piece 140, the brake cable 120 can be connected to the brake piece 140, so that the brake piece 140 can not move along with the locking arm 130 when the locking arm 130 moves, and the problem that the brake cable 120 is loosened because the part of the brake cable 120 connected to the locking arm 130 moves along with the locking arm 130 when the vehicle is locked is further avoided; in addition, if a tensioning structure is adopted which is installed on the brake disc 150 and directly acts with the brake cable 120, when the bicycle is locked, the brake cable 120 is tensioned by the tensioning structure so as to avoid the brake cable 120 from loosening, and in the process of repeatedly locking and unlocking the bicycle, the tensioning structure and the brake cable 120 repeatedly act to easily cause the brake cable 120 to be worn, thereby reducing the service life of the brake cable 120, and through the roller brake provided by the embodiment of the application, by attaching brake cable 120 to brake member 140, brake member 140 can not move with latch arm 130, the problem of the slack of the brake cable 120 caused by the movement of the portion of the brake cable 120 connected to the locker arm 130 along with the locker arm 130 does not occur, and then the tensioning structure is not needed, the abrasion of the brake cable 120 caused by the tensioning structure can be avoided, and the service life of the brake cable 120 is prolonged.

In one embodiment of the present application, the brake system provided by the embodiment of the present application includes a brake cable 120, and the brake member 140 is connected to the brake cable 120. Because the brake cable 120 is connected to the brake piece 140, when the bicycle is locked, the brake piece 140 can not move along with the bicycle locking arm 130, and the problem that the brake cable 120 is loosened due to the fact that the bicycle locking arm 130 drives the brake cable 120 to move along with the bicycle locking arm is solved. Of course, it is also possible to attach the brake cable 120 to the other positions of the locking arm 130 or the roller brake, or to attach the locking cable 110 to the brake 140 for a different or the same purpose.

A third aspect of the present application provides a vehicle including the brake system provided in the embodiment of the present application.
