The palm simulation device 3 is fixed to the fixed bracket 1, and the palm simulation device 3 performs a door opening or closing action. The palm simulation device 3 includes a moving component 31, a control component 32, a finger mechanism fixing plate 33, a guide rail 34, a front baffle 35 and a rear baffle 36. Among them, the moving component 31 moves forward and backward and performs a door opening or closing action. The control component 32 is connected to the moving component 31 to control the moving component 31 to move forward and backward. The finger mechanism fixing plate 33 is fixed to the fixed bracket 1 by bolts. In this embodiment, the finger mechanism fixing plate 33 is fixed to the fixed bracket 1 by 4 bolts. The guide rail 34 is fixed to the finger mechanism fixing plate 33 by bolts. The front baffle 35 is fixed to the finger mechanism fixing plate 33 by bolts. In this embodiment, the front baffle plate 35 is fixed to the finger mechanism fixing plate 33 by two bolts. The rear baffle plate 36 is fixed to the finger mechanism fixing plate 33 by bolts. In this embodiment, the rear baffle plate 36 is fixed to the finger mechanism fixing plate 33 by two bolts.

[0039] In this embodiment, the motion component 31 includes: a finger simulation block 311, a palm simulation block 312 and a slider 313. Among them, the finger simulation block 311 simulates finger movements. The palm simulation block 312 simulates palm movements and is fixed to the finger simulation block 311 by bolts. In this embodiment, preferably, the palm simulation block 312 is fixed to the finger simulation block 311 by two bolts. The slider 313 is fixed to the palm simulation block 312 by bolts. In this embodiment, preferably, the slider 313 is fixed to the palm simulation block 312 by four bolts.

[0040] In this embodiment, the control member 32 includes: a guide rod 321, a limit block 322, and a spring 323. The guide rod 321 is screwed onto the moving member 31 through a thread, and is fixed and locked by a nut 324. The limit block 322 is sleeved on the guide rod 321. The spring 323 is sleeved on the guide rod 321 and is located between the limit block 322 and the nut 324 to realize the automatic return of the moving member 31.

[0041] In this embodiment, the slider 313 slides freely on the guide rail 34, and the front baffle 35 prevents the slider 313 from falling off the guide rail 34 when the slider 313 moves beyond the limit.

[0042] In this embodiment, an opening is provided in the middle of the rear baffle plate 36 , and the guide rod 321 passes through the rear baffle plate 36 to pull the moving component 31 to move forward and backward.

[0043] In this embodiment, a winding drum 6 is provided at the bottom of the motor assembly 2, and the winding drum 6 is fixed to the guide rod 321 through the pull wire 7 passing through the fixing bracket 1. When the motor assembly 2 rotates, the winding drum 6 rotates accordingly to adjust the length of the pull wire.

[0044] In this embodiment, the stroke control of the palm simulation device 3 includes a limit block 322 and a motor control program. The stroke control limits the stroke range of the moving component 31. The limit block 322 sets the physical boundary to perform hard stroke limit, and the motor control program sets the program to perform soft stroke limit. Among them, the stroke range is the movement boundary of the moving component 31. The motor control program sets the stroke range for the sliding of the moving component 31. When the moving component 31 approaches or reaches the stroke range, the motor control program will automatically issue an instruction to stop the moving component 31 from moving or changing the direction of movement, thereby preventing the device from exceeding the predetermined stroke range. At the same time, the limit block 322 will also prevent the moving component 31 from exceeding the stroke range. The present invention sets double protection for the sliding of the moving component 31.

[0045] In this embodiment, the fixing bracket 1 is in the shape of a letter "X", and the raised parts at both ends are adjusted according to the shape of the door. In this embodiment, the fixing bracket is preferably a trumpet-shaped opening, the size of which can be adjusted according to the size of the semi-hidden handle of the door, and the raised parts at both ends are fixed to the door by rivets.

[0046] In this embodiment, the semi-hidden door handle unlocking device also includes two motor fixing brackets, wherein the two motor fixing brackets are fixedly connected to each other on one side, the motor assembly 2 is connected to the fixing bracket 1 through the motor fixing bracket, and the other side is respectively connected to the fixing bracket 1 and the motor assembly 2, the motor fixing bracket is L-shaped, and a waist-shaped hole is also provided on the motor fixing bracket to achieve multi-directional adjustment. This embodiment is preferred, such as Figure 2 , Figure 3bAs shown, the motor fixing bracket A4 is fixed to the fixing bracket 1, the motor fixing bracket B5 is connected to the motor assembly 2, and the motor fixing bracket A4 is vertically connected to the motor fixing bracket B5, wherein the connection part between the motor fixing bracket A4 and the motor fixing bracket B5 is designed as a waist-shaped hole, and the connection part between the motor fixing bracket B5 and the motor assembly 2 is designed as a waist-shaped hole. The design of the waist-shaped hole allows the parts matched with it to be moved or adjusted within a certain range. Inserting a screw into the waist-shaped hole at the connection part can ensure the tight connection between the motor fixing brackets and between the motor fixing bracket B5 and the motor assembly 2. At the same time, the screw can slide along its length direction in the waist-shaped hole, driving the mutual sliding between the motor fixing brackets and between the motor fixing bracket B5 and the motor assembly 2, ensuring that the motor assembly 2 is adjustable in three directions of the X-axis, the Y-axis, and the Z-axis, thereby ensuring a precise handle angle.

[0047] In this embodiment, the motor assembly 2 electrically rotates at a certain angle to drive the palm simulation device 3 to move, simulating a user opening the semi-hidden handle of a car door.

[0048] An operating method of a semi-hidden door handle unlocking device according to an embodiment of the present invention is as follows: according to the size of the semi-hidden door handle, adjust the opening size of the fixed bracket, and fix the fixed bracket to the door by rivets. Start the door touch program, control the motor assembly to rotate, the door machine assembly drives the pull rope to rotate through the winding drum, the pull rope drives the control component to move, and the control component controls the moving component to slide.
