This situation is particularly obvious. The long-term high-intensity operation not only increases the fatigue of the driver, but also may lead to poor parking brake effect, resulting in vehicle slipping and potential safety hazards.

[0029] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0030] In the existing parking brake operating mechanism, the driver needs to apply a relatively large force to effectively operate the parking brake, especially when parking for a long time or on a slope, this situation is particularly obvious. The long-term high-intensity operation increases the fatigue of the driver.

[0031] In view of this, the embodiments of the present application provide a parking device and a vehicle. By providing a brake lever mechanism between the operating mechanism and the brake, the braking operation force of the driver during parking is amplified, and the driver can achieve parking with a smaller force, thereby reducing the operation fatigue of the driver during long-term parking and improving the driving experience.

[0032] The following refers to Figures 1 to 2 , to describe the parking device according to the embodiments of the first aspect of the present utility model. The parking device can be used for a vehicle and can include: an operating mechanism, a brake, and a brake lever mechanism.

[0033] The operating mechanism is usually used to control the parking brake system of a vehicle to ensure that the vehicle does not move when parked. In this embodiment, the operating mechanism can be a mechanical operating mechanism, such as a handbrake lever or a foot-operated parking brake, or a hydraulic operating mechanism, such as a hydraulic parking brake.

[0034] The brake is a device that keeps the vehicle in a stationary state under the action of braking force. In this embodiment, the parking brake can be a drum brake or a disc brake.

[0035] The brake lever mechanism 100 may include: a fixed bracket 110, a rocker arm 120, and a screw device 130. The fixed bracket 110 is fixed to the vehicle body, and a first rotating shaft 140 is provided on the fixed bracket 110. The rocker arm 120 is swingably connected to the fixed bracket 110 around the first rotating shaft 140. The rocker arm 120 has a first connection point 120a and a second connection point 120b. The distance between the first connection point 120a and the first rotating shaft 140 is greater than the distance between the second connection point 120b and the first rotating shaft 140. Thus, a first force arm is formed between the first connection point 120a on the rocker arm 120 and the axis of the first rotating shaft 140, and a second force arm is formed between the second connection point 120b and the first rotating shaft 140. The first force arm is greater than the second force arm, so that the rocker arm 120 forms a lever structure with the fulcrum at the first rotating shaft 140. The braking operating force is output from the first connection point 120a, and after being amplified by the lever structure formed by the rocker arm 120, it is output from the second connection point 120b, enabling the driver to use a smaller braking operating force to park the vehicle.

[0036] The first connection point 120a is connected to the operating mechanism through a first brake cable, and the second connection point 120b is in transmission connection with the screw device 130. For example, the screw device 130 can be fixedly connected to the second connection point 120b to move together with the rocker arm 120, or the screw device 130 can also be rotatably connected to the rocker arm 120 through a transmission pin passing through the second connection point 120b. The screw device 130 is connected to the brake through a second brake cable. Thus, when the driver applies the parking brake, a braking operating force is applied to the operating mechanism, which is transmitted to the brake lever mechanism 100 through the first brake cable, driving the rocker arm 120 to swing around the first rotating shaft 140, moving the screw device 130, outputting the amplified braking operating force, and driving the brake through the second brake cable to park the vehicle.

[0037] For the parking device of the present utility model, when the driver applies the braking force during braking, a braking force is applied to the operating mechanism, and the first braking cable is pulled to drive the rocker arm 120. The rocker arm 120 rotates around the first rotating shaft 140. A first force arm is formed between the first connection point 120a on the rocker arm 120 and the axis of the first rotating shaft 140, and a second force arm is formed between the second connection point 120b and the first rotating shaft 140, forming a lever structure. The first force arm is greater than the second force arm, amplifying the braking force. Compared with the prior art, the driver can operate the parking device of the present application with a smaller braking force to park the vehicle. While ensuring the parking effect, it also reduces the fatigue of the driver during long-time parking operation, is more labor-saving, and is beneficial to improving the driving experience of the driver.

[0038] In some embodiments, the fixed bracket 110 may include a bracket main body 111 and legs 112. The bracket main body 111 has an installation surface, and a first pivot hole is provided on the installation surface. The first pivot hole penetrates the installation surface along the axial direction of the first rotating shaft 140. A second pivot hole corresponding to the first pivot hole is provided on the rocker arm 120. The first rotating shaft 140 passes through the first pivot hole and the second pivot hole, and the rocker arm 120 and the bracket main body 111 are rotationally connected through the first rotating shaft 140.

[0039] A plurality of legs 112 are provided, and the plurality of legs 112 are distributed on the periphery of the bracket main body 111 and are connected to the vehicle body. In this way, the stress received by the fixed bracket 110 can be evenly dispersed through the legs 112, improving the structural strength and stability of the fixed bracket 110 and ensuring the working stability of the parking device.

[0040] Further, there are two legs 112, and the two legs 112 are distributed on opposite sides of the bracket main body 111. The symmetrical arrangement is conducive to further dispersing the acting force received by the fixed bracket 110 and improving the stability of the structure.

[0041] The leg 112 may include: a first section 1121 and a second section 1122. One end of the first section 1121 is connected to the installation surface, the other end of the first section 1121 is connected to the second section 1122, and the second section 1122 is parallel to the installation surface. In this way, the first section 1121 and the second section 1122 form an L-shaped connection structure 122, facilitating the installation of the fixed bracket 110 on the vehicle.

[0042] A first fixing hole 1123 is provided on the second section 1122, and a second fixing hole is provided on the vehicle body. The first fastener sequentially passes through the first fixing hole 1123 and the second fixing hole to fixedly connect the leg 112 and the vehicle body. In this way, the fixed bracket 110 can be installed on the vehicle body through the first fastener, with a simple structure and convenient installation of the fixed bracket 110, which is beneficial to improving production efficiency. At the same time, the fixed bracket 110 can also be removed by removing the first fastener, facilitating maintenance and replacement.

[0043] Optionally, the first fastener can be a screw, a bolt and nut, or a pin. In this way, it is beneficial to save the material cost of the parking device.

[0044] In some embodiments, the rocker arm 120 may have a first end 120c and a second end 120d opposite to each other along its long axis. The first connection point 120a is located at the first end 120c. One of the first rotating shaft 140 and the second connection point 120b is provided at the second end 120d, and the other is provided in the region between the first end 120c and the second end 120d. For example, the first rotating shaft 140 is provided at the second end 120d, and the second connection point 120b is provided in the region between the first end 120c and the second end 120d. Or, the second connection point 120b is provided at the second end 120d, and the first rotating shaft 140 is provided in the region between the first end 120c and the second end 120d. In this way, the transmission path of the braking force input from the first brake cable to the rocker arm 120 on the rocker arm 120 is optimized, the load is effectively dispersed, and the structural influence of the single-point force on the rocker arm 120 is reduced, thereby enhancing the overall stability and torsional resistance of the rocker arm 120 and improving the reliability during the braking operation of the parking device.

[0045] Furthermore, the first rotating shaft 140 is provided at the second end 120d, and the second connection point 120b is located between the first end 120c and the second end 120d. When the first brake cable pulls the rocker arm 120 to swing, the rocker arm 120 drives the screw device 130 to move in the same direction as the second brake cable and the first brake cable. The layout of the first brake cable and the second brake cable is simple, which is beneficial to improving the production efficiency of the vehicle.

[0046] It can be understood that the designer can reasonably arrange the positions of the first rotating shaft 140 and the second connection point 120b according to the vehicle model to optimize the movement trajectory and angular change of the rocker arm 120, thereby improving the control precision of the parking device, ensuring that the brake is more stable and accurate when applying and releasing the braking force, and enhancing the parking safety of the vehicle.

[0047] According to some embodiments of the present utility model, the rocker arm 120 may include a rocker arm body 121 and a connection structure 122. Both the first connection point 120a and the second connection point 120b are provided on the rocker arm body 121, making the overall structure of the brake lever mechanism 100 more concise and compact, reducing unnecessary complex components and connection points, and lowering the manufacturing and assembly difficulty and cost of the parking device. The connection structure 122 is provided at the second connection point 120b and is movably connected to the screw device 130. For example, the screw device 130 may be rotatably connected to the connection structure 122, or the screw device 130 may also be slidably connected relative to the connection structure 122. When the rocker arm body 121 swings, it can drive the screw device 130 to move together, output an amplified braking operation force to the second brake cable on the screw device 130, and drive the brake to brake the vehicle.

[0048] By optimizing the design of the rocker arm body 121 and the connection structure 122, the stress concentration and fatigue damage suffered by the brake lever mechanism 100 during operation can be reduced, thereby extending the service life of the parking device.

[0049] In some embodiments of the present utility model, the connection structure 122 may include a connection pin 122a and a connecting member 122b. The connection pin 122a is parallel to the first rotating shaft 140. One end of the connection pin 122a penetrates through the rocker arm body 121. In other words, the connection pin 122a passes through the rocker arm body 121 from the second connection point 120b, and the connection pin 122a is rotatable relative to the rocker arm body 121. The other end of the connection pin 122a extends to the lower side of the rocker arm body 121, providing a stable connection fulcrum for the connecting member 122b.

[0050] The connecting member 122b is rotatably provided at the end of the connection pin 122a away from the rocker arm body 121, and the screw device 130 is fixedly connected to the connecting member 122b. For example, the connecting member 122b may be riveted to a part of the screw device 130 (the screw body 131 hereinafter), or the connecting member 122b may also be screwed and fixed to a part of the screw device 130. During the swinging process of the rocker arm body 121, the screw device 130 moves together. At the same time, the screw device 130 can also rotate relative to the connection pin 122a.

[0051] In the structural layout of the vehicle, for the convenience of wiring, the routing directions of both the first brake cable and the second brake cable are fixed by wire harness fixing structures such as buckles. The screw device 130 connected to the second brake cable can rotate relative to the connection pin 122a during the swinging process of the rocker arm 120. In this way, the radial force exerted by the screw device 130 on the second brake cable is reduced, which is beneficial to extending the service life of the connection structure 122 between the screw device 130 and the second brake cable.

[0052] According to some embodiments of the present utility model, the screw device 130 may include a screw body 131, an adjustment thread section 132, and a balance weight 134. The screw body 131 is fixedly connected to the connecting member 122b. The adjustment thread section 132 is provided at one end of the screw body 131 away from the connecting member 122b. The balance weight 134 is in threaded cooperation with the adjustment thread section 132, and the balance weight 134 is fixedly connected to the second brake cable. A first limiting member 133 is provided at one end of the adjustment thread section 132 away from the connecting member 122b. In this way, the relative position of the balance weight 134 can be adjusted along the axial direction of the screw body 131 to match the second brake cables of different lengths of different vehicle models. Through the first limiting member 133, the balance weight 134 can be prevented from falling off the screw body 131, improving the reliability of the screw device 130.

[0053] Optionally, the first limiting member 133 may include, but is not limited to, a nut, and the nut is screwed onto one end of the adjustment thread section 132 away from the connecting member 122b. In this way, it is beneficial to save material costs.

[0054] The screw device 130 may further include a second limiting member 135. A limiting hole along the radial direction of the screw body 131 is provided on the balance weight 134. The second limiting member 135 is provided in the limiting hole, and the second limiting member 135 abuts against the adjustment thread section 132. The second limiting member 135 may be a cylindrical member. An external thread is provided on the outer wall of the second limiting member 135, and an internal thread is provided in the limiting hole. The second limiting member 135 is threadedly connected to the threaded hole, and the second limiting member 135 abuts against the adjustment thread section 132. In this way, the relative position of the balance weight 134 on the screw body 131 can be fixed, thereby improving the reliability of the braking of the parking device.

[0055] According to some embodiments of the present utility model, the rocker arm 120 may further include a return spring member 150. The return spring member 150 is provided on the side of the rocker arm body 121 facing the screw device 130. One end of the return spring member 150 is connected to the rocker arm body 121, and the other end is connected to the vehicle body. In this way, driven by the braking operating force input by the driver, the rocker arm body 121 swings towards the side away from the screw device 130. Through the amplification effect of the braking lever mechanism 100, the brake is driven to apply parking braking to the vehicle. When the driver releases the operating mechanism and moves the vehicle, the return spring member 150 drives the rocker arm body 121 to reset, driving the second brake cable to release the brake, improving the reliability of the vehicle's switching between the driving state and the parking state.

[0056] In a second aspect, an embodiment of the present utility model further provides a vehicle, including the above-mentioned parking device.

[0057] For the vehicle of the present utility model, due to the use of the above-mentioned parking device, by arranging a braking lever mechanism 100 between the operating mechanism and the brake, the braking operation force of the driver during parking is amplified, and the driver can achieve parking with a smaller force, thereby reducing the operation fatigue of the driver during long-time parking and enhancing the driving experience of the driver.
