Description

Technical Field

[0001] This utility model relates to the field of automotive assembly technology, and in particular to an online assembly and inspection device for mechanical handbrakes. Background Technology

[0002] The handbrake is an essential component of a car's braking system, used for parking on slopes or preventing the vehicle from rolling away in special circumstances. Its assembly must meet the relevant national standards for slope parking.

[0003] After the handbrake is assembled on the production line, it needs to be pulled up and down repeatedly before the vehicle leaves the production line. The main purposes are: 1. to eliminate the fit gaps between the various parts of the mechanical handbrake system and the elongation of the cable; 2. to adjust the gaps between the relevant parts of the brake, so as to ensure that the handbrake system is in the best condition when in use.

[0004] In traditional assembly line operations, assemblers must enter the driver's cab and manually pull the mechanical handbrake to its limit, repeating this pull-up and release 10 times before checking the handbrake's tension. Furthermore, the handbrake must be pulled up again during the online assembly of the center console trim cover. This entire process is labor-intensive and costly. Moreover, operators performing these tasks need extensive experience and high skill levels. However, because different operators perceive different tension levels, and even the same person perceives different tension levels for different vehicles each time, the quality of online handbrake checks cannot be guaranteed. In addition, with the accelerating pace of automotive production, the time required for assembly line operations is increasingly shorter. The aforementioned time-consuming and inefficient processes severely impact the stability of the production cycle. Summary of the Invention

[0019] Figure 2 yes Figure 1 Rear view. Detailed Implementation

[0020] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0021] like Figure 1 , 2 As shown, the online assembly and inspection device for the mechanical handbrake of this utility model includes a base 1 installed on the vehicle floor. A positioning pin 2 adapted to the steering column hole of the mechanical handbrake M is provided on the side of the base 1. The positioning pin 2 is rotatably connected to one end of a rocker arm 3, and the other end of the rocker arm 3 is provided with a handbrake fixing component 4 and a handbrake button drive assembly.

[0022] The aforementioned handbrake fixing component 4 is divided into a fixed end and a locking end. The fixed end is fixed to the rocker arm 3 by two fastening bolts 41, and the locking end is an open slot adapted to the mechanical handbrake M, which is located below the mechanical handbrake M. After the mechanical handbrake M is inserted into the positioning pin 2, it is locked in the open slot of the handbrake fixing component 4, and the mechanical handbrake M can rotate together with the rocker arm 3.

[0023] The handbrake button drive assembly includes an electric push rod 51 located below the rocker arm 3. One end of the electric push rod 51 is connected to the rocker arm 3 via a fixed bracket 52, and the other end is provided with a button pressing block 53. The button pressing block 53 is positioned opposite the handbrake button, and can be pushed or released from the button pressing block 53 under the action of the electric push rod 51. When the handbrake button is in the pressed state, the mechanical handbrake can be easily pulled up and released until the required number of times is completed. Preferably, the handbrake button drive assembly also includes a guide member 54 located at the tail of the rocker arm 3. The guide member 54 is a U-shaped structure located on both sides of the button pressing block 53. The button pressing block 53 has sliding grooves on both sides, which are slidably connected to the guide member 54.

[0024] To enable the rocker arm 3 and the mechanical handbrake M to automatically raise and lower, a drive assembly is also provided on the base 1. The drive assembly includes a turntable 61 positioned on the same side as the rocker arm 3. A connecting rod 62 is provided between the turntable 61 and the rocker arm 3. One end of the connecting rod 62 is connected to the middle of the rocker arm 3, and the other end is eccentrically connected to the turntable 61. The turntable 61 is driven by a reversible motor 63 located within the base 1, and the output shaft of the reversible motor 63 is connected to the center of the turntable 61. When the reversible motor 63 rotates continuously in one direction, the rocker arm 3 and the mechanical handbrake M can be repeatedly raised and lowered due to the action of the eccentric connecting rod 62. After testing, the reversible motor 63 is usually rotated in the opposite direction to stop the mechanical handbrake M in a vertical position.

[0025] To achieve unattended operation and automatic detection, this utility model also includes a control unit. The control unit includes a magnetic counter 71 mounted on the top cover of the base 1 for detecting the number of rotations of the turntable. The signal output terminal of the magnetic counter 71 is connected to the signal input terminal of the control center, and the control output terminal of the control center is connected to the control input terminal of the turntable drive mechanism (i.e., the forward and reverse motor 63) and the control input terminal of the handbrake button drive assembly (i.e., the electric push rod 51), respectively.

[0026] Normally, the distance between the center of the turntable 61 and the top cover of the base 1 is less than the radius of the turntable 61, and a magnet block 72 is installed around the periphery of the turntable 61, which is inductive to the counting module of the magnetic counter 71. The magnetic counter 71 counts once for each rotation of the turntable 61.

[0027] In addition, a rechargeable battery is installed inside the base 1 as a power supply, and a power switch is provided on the top cover of the base 1.

[0028] In use, the base 1 is placed on the vehicle floor to provide support. Simultaneously, the steering column hole of the mechanical handbrake M is fitted onto the positioning pin 2, and the mechanical handbrake M is secured to the handbrake fixing part 4 on the rocker arm 3, allowing both to rotate simultaneously. Then, the power switch is turned on, causing the forward / reverse motor 63 to drive the turntable 61 to rotate forward. Simultaneously, the electric push rod 51 operates, pressing the handbrake button into place via the button press block 53, facilitating the rocker arm 3 to drive the mechanical handbrake M to pull up and down according to the counting requirements. When the forward / reverse motor 63 rotates forward to the second-to-last count, the motor reverses, and the electric push rod 51 releases the handbrake button. At this point, the mechanical handbrake M is in an upright position, and the forward / reverse motor 63 reverses back to the starting position, facilitating the inspection of the next vehicle.

[0029] It should be noted that in the description of this utility model, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", and "outer" indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
