[0084] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The jacquard device mentioned in this embodiment is innovative in that male and female electrical connection devices are distributed on the left and right sides of the jacquard device, and the connection devices enable the jacquard device to complete the connection of various electrical signals required by the jacquard device while being installed. Since the connection of electrical signals is completed through the electrical connection devices on both sides of the jacquard device, it is different from the conventional jacquard device, and each jacquard device does not need to have a drive connection line at the tail.

[0085] Referring to FIG. 4 , in the wireless jacquard device 111 , since there are no multiple drive connection lines at the tail, a lot of installation space is saved, which means that the application range of this type of wireless jacquard device 111 is wider, especially in the occasions where the installation space is strictly limited.

[0086] Reference Figure 4 Compared with the existing jacquard jacquard device, the wireless jacquard jacquard device 111 eliminates the tail drive connecting wire and the corresponding process of the connecting wire, so the cost of the wireless jacquard jacquard device 111 is also reduced accordingly.

[0087] Example 2, refer to Figure 1 , Figure 3 , Figure 4 , Figure 6 Fig.11 and Fig.12 The difference between the second embodiment and the first embodiment is that: a driving circuit is provided on both the first printed circuit board 12 and the second printed circuit board 23, and the driving circuit is used to drive the piezoelectric ceramic piece 42 to swing left and right. A jacquard needle is provided at the front end of the piezoelectric ceramic piece 42. After the piezoelectric ceramic piece 42 swings left and right, the jacquard needle is driven to swing left and right.

[0088] Reference Fig.11 and Fig.12The driving circuit includes a power supply DC1, a power supply DC2, a resistor R1, a resistor R2, a resistor R3, a capacitor C1, a capacitor C2, a diode D1, a diode D2, a diode D3, a diode D4, a diode D5, a transistor Q1, a transistor Q2, a 5V power supply and a control signal input terminal INPUT.

[0089] Reference Fig.11 , one end of the resistor R3 is electrically connected to the 5V power supply, the other end of the resistor R3 is electrically connected to the base of the transistor Q2, the control signal input terminal INPUT is electrically connected to the emitter of the transistor Q2, the collector of the transistor Q2, the cathode of the diode D5, the base of the transistor Q1 and one end of the resistor R1 are connected together, the base of the transistor Q1, the other end of the resistor R1 and one end of the power supply DC1 are connected together, the emitter of the transistor Q1, the anode of the diode and one end of the resistor R2 are connected together, one end of the capacitor C2, the other end of the resistor R2 and the cathode of the diode D4 are connected together, the anode of the diode D4 is electrically connected to the anode of the diode D3, the cathode of the diode D2, the cathode of the diode D3, one end of the capacitor C1 and the other end of the capacitor C2 are connected together, the anode of the diode D2 is electrically connected to the anode of the diode D1, the cathode of the diode D1, the other end of the capacitor C1, the other end of the power supply DC1 and one end of the power supply DC2 are connected together, and the other end of the power supply DC2 is grounded.

[0090] Reference Fig.11 By setting the diode D1, the diode D2, the diode D3, and the diode D4 to form a capacitor charging and discharging circuit, on the one hand, the common point between the capacitor C1 and the capacitor C2 does not need to be grounded, and on the other hand, the life of the piezoelectric ceramic piece 42 is linearly related to the forward voltage. When the piezoelectric ceramic piece 42 is subjected to the same voltage, when the charging direction is from C2 to C1, D1 and D2 share a part of the voltage with C1, so that the voltage borne by C2 decreases accordingly, but the strength remains unchanged. When the charging direction is from C1 to C2, D1 and D2 share a part of the voltage with C2, so that the voltage borne by C1 decreases accordingly, but the strength remains unchanged. The final result is that, under the premise of unchanged strength, the forward voltage borne by the piezoelectric ceramic piece 42 is reduced, and the service life of the piezoelectric ceramic piece 42 is extended.

[0091] Reference Fig.11 The driving circuit has the characteristics of a small number of components and is easy to integrate, and has a piezoelectric ceramic piece 42 with positive and negative voltage driving functions.

[0092] Reference Fig.11 , diode D2 is a voltage regulator, and diode D3 is a voltage regulator.

[0093] Reference Fig.11Capacitor C1 and capacitor C2 are equivalent capacitors of two piezoelectric ceramic pieces 42 respectively. At any time, only one of capacitor C1 and capacitor C2 is in a charging state and the other is in a discharging state, so that the piezoelectric ceramic piece 42 swings left and right.

[0094] Reference Fig.11 , power supply DC1 is a high voltage direct current power supply, and power supply DC2 is a high voltage direct current power supply.

[0095] Working principle of driving circuit:

[0096] Reference Fig.12 , 1. The input signal of the signal input terminal INPUT is input from the emitter (E pole) of Q2, and the signal is a 5VTTL signal. When the control signal of the signal input terminal INPUT is high level, since the base (B pole) of Q2 is connected to the 5V power supply through R3, at this time, the voltage difference between the E pole and the B pole of Q2 is 0, then Q2 will be in the cut-off state; the DC power supply DC1 provides current to the base (B pole) of Q1 through R1, which flows out from the emitter (E pole) of Q2 after amplification by Q1, and then charges the piezoelectric ceramic 42 through R2. The resistor R2 is a current limiting resistor here, which plays a role in limiting the charging current. Since Q2 is in the off state, DC2 has no effect at this time. Finally, the direction of the voltage in the figure is high at point B and low at point C, and the charging direction is from B to C.

[0097] Reference Fig.12 , 2. When the input control signal of the signal input terminal INPUT is low level, +5V flows through the base of Q2 through R3, and Q2 will be in the on state; after Q2 is turned on, its collector (C pole) is approximately 0 when the Q2Vce voltage drop is ignored. Therefore, under the clamping action of D5, Q1 will quickly enter the cut-off state, at which time DC1 has no effect, and DC2 enters from point C, and reversely charges the circuit through R2 and Q2. Finally, the voltage direction in the figure is high at point C and low at point B, and the charging direction is from C to B.

[0098] Reference Fig.12, take point B as high and point C as low, that is, the charging direction is from B to C. At this time, D4 ​​is reverse biased and does not work, and the charging voltage is charged to C2 and C1. Since D2 is a voltage regulator, when the voltage Vac of C1 is greater than the voltage regulation value of D2, D2 will be turned on, so that the voltage Vac of C1 is equal to the voltage regulation value of D2. Usually, the voltage regulation value of D2 is about 10~30V, so C2 will form a normal high-voltage charge, while C1 is a negative low-voltage charge, and the sum of the two voltages is equal to the DC1 voltage. The reason and benefit of doing so are: the life of the piezoelectric ceramic piece 42 is linearly related to the forward voltage. The higher the voltage, the greater the swing force but the shorter the life. After adding D1 to D4, when the piezoelectric ceramic piece 42 is subjected to the same voltage, D1 and D2 share part of the voltage with C1, so that the voltage borne by C2 decreases accordingly, but the force remains unchanged. The final result is that under the premise of unchanged force, the forward voltage borne by the piezoelectric ceramic piece 42 is reduced, and the service life of the piezoelectric ceramic piece 42 is extended. Similarly, when C is high and B is low, the reasoning is the same. At this time, C1 releases the negative pressure and in turn bears the positive high pressure. C2 discharges through Q2 and shares part of the negative pressure. The process is similar to the above.

[0099] Reference Figure 1 and Figure 3 The piezoelectric ceramic element includes at least one glass fiber sheet, two piezoelectric ceramic sheets 42 respectively wrapped on the left and right sides of the glass fiber sheet, and two copper foil electrical terminals respectively arranged on the left and right sides of the glass fiber sheet. The two copper foil electrical terminals are respectively electrically connected to the tails of the corresponding piezoelectric ceramic sheets 42, and the front part of the glass fiber sheet is connected to the jacquard needle. The voltage output by the driving circuit is applied to the piezoelectric ceramic sheet 42 to drive the piezoelectric ceramic sheet 42 to swing, and the glass fiber sheet is an insulating layer.
