The above is a multi-functional safety weight bench structure combination embodiment. The following describes the selection and implementation of the damper 116 used in the multifunctional safety weight bench. The damper 116 can select different types of dampers, such as optional, electromagnetic damping, self-generating. Damping type, hydraulic damping type, friction damping type, but in the technical solution of the present invention, the purpose of the present invention is to achieve the object of the invention, which is simple in structure and convenient in control. If the present invention uses hydraulic damping type and friction damping type as the damper 116, the two types of dampers are different from the charged control damping type in that the program switching function using the electronic control is changed to the one-way force using the ratchet. The principle, combined with the mechanical shifting mode to replace the function of the program switch. Since these two types of dampers are not preferred embodiments of the present invention, they are optional and will not be described in detail herein. Electromagnetic damping, self-generating damping, and the preferred embodiments of the two types of dampers are now described separately.

Embodiment 1, the damper 116 uses an electromagnetic damper

The electromagnetic damper can be selected from hysteresis electromagnetic damper, eddy current electromagnetic damper and acute-angle magnetic electromagnetic damper. Among them, the selection of acute-angle magnetic electromagnetic damper is the best choice. The reason is that the hysteresis electromagnetic damper is expensive; the eddy current electromagnetic damper has a small damping force at low speed; the acute-angle magnetic electromagnetic damper has a large damping force at low speed, and the eddy current electromagnetic damper has a damping force of 1-2 times, which does not need The shifting device can be directly connected to the lower drive shaft 112, which makes the structure simpler and more cost-effective.

In this embodiment, an acute magnetic damper is used as the damper of the embodiment, and an excitation power supply system is provided in the acute magnetic damper. As shown in FIG. 5, the power supply system includes an electromechanical program switching circuit portion. The function of the components in the power supply system is as follows: The power supply s adopts the city 220v or 110v, and the K1 string with the switch stepless governor can adjust the excitation current in the AC circuit. The rectifier D adopts the bridge rectification method, L is the acute-angle magnetic damper excitation winding, and the self-inductive discharge is generated when the L-on current is broken, and C is set to protect the K4 and K6 contacts.

In Figure 5, k2, k3, k4, k5, and k6 belong to the program switch circuit part (the part enclosed by the dotted line in Fig. 5), and the working procedures are: the whole process bidirectional damping force first program switch k2, the one-way upward damping force second Program switches k3 and k4, one-way downward damping force third program switches k5 and k6.

Excitation power supply system Figure 5 circuit connection method is as follows: with switch stepless governor K1 and power supply circuit in series, connected to the rectifier D AC input; first program switch K2, second program switch K3 and K4, third program switch K5 And K6 form a parallel program switching circuit, the first node of the parallel program switching circuit is connected with the first contact of the output end of the rectifier D to form a common contact 51; the excitation coil L and the capacitor C form a parallel circuit, and the first node and the parallel program of the parallel circuit The second contact of the switch circuit is connected to form a common contact 52. The second contact of the parallel circuit is connected with the second contact of the output of the rectifier D to form a common contact 53.

Fig. 4b is an electromechanical program switch mechanical portion 115 which is composed of a friction wheel 132, a movable contact with a contact slider J134, K4, and K6, and is supplied by the friction wheel 132 to an action force with a contact slider J134.

Fig. 6 is a schematic view showing the mechanical part and the circuit part of the electromechanical program switch. The circuit in Fig. 6 is an important part of the circuit of the excitation power supply system of Fig. 5. The friction wheel 132 and the contact sliders J134, K4 and K6 in Fig. 6 belong to the mechanical part of the electromechanical program switch (the part enclosed by the dotted line in Fig. 6); and K2, K3, K4, K5, K6 belong to the electromechanical program switch Circuit part. Their combination constitutes a completely controllable excitation power supply system. It should be noted that K4, K6 are both circuit parts and mechanical parts.

Figure 5 circuit component installation method is K2, K3, K5 combination is installed in the control display panel, K1 is installed separately on the control display, power supply terminal, bridge rectifier, protection capacitor C is installed on the same circuit board Then, the box is closed and fixedly mounted on the inner side of the base 106; the movable joints of K4 and K6 are connected with the slider J134, which is a mechanical part of the electromechanical program switch, and is installed at one end of the damper 116, and the components are connected by wires.

Referring to FIG. 6 and FIG. 4b, the working principle of the electromechanical program switch is further explained. When the operator is training, the operating rod 104 reciprocates back and forth, and the damper 116 is driven by the transmission belt 118, the transmission wheel 117 and the transmission shaft 112 to rotate forward and backward. In the electromechanical program switching circuit, since K2, K3, and K5 are gear combination switches, and the circuit is in parallel relationship, and K3 and K4 are in series circuit relationship, and K5 and K6 are in series circuit relationship, under the premise of this circuit relationship The movable joints of K4 and K6 are respectively installed at the two ends of the slider J. When the operator moves the operating lever, the friction wheel will provide a constant force to the slider J in a single stroke time, so that K4 One of the K6 switches is turned on. When the operator changes the direction of travel, K4, K6 will be changed accordingly to switch on the other switch.

The specific working procedure of the electromechanical program switch is that when the operator selects the first two-way damping force first program, the switches K3 and K5 are in the off state, the switch K2 is connected to the coil L, and the current is supplied to the coil L through the switch K2. The bidirectional excitation current of the stroke generates a full-way bidirectional damping force; when the operator selects the single-pass upward damping force second program, the switches K2 and K5 are in the off state at this time, and the switches k3 and k4 form the series circuit and the coil L is connected. The operator only turns on the switch K4 during the upward stroke, and the current provides a one-way upward excitation current to the coil L through the switches K3, K4, generating a one-way upward damping force; when the operator selects the one-way downward damping force third program, this When the switches K2 and K3 are in the off state, the switches k5 and k6 form a series circuit and the coil L is turned on. At this time, the operator is only turned on in the downward stroke, and the current is supplied to the coil L through the switches K5 and K6. One-way downward excitation current produces a one-way downward damping force. Thus, regardless of how the operator moves, only the excitation current is supplied to the acute-angle magnetic damper to generate a corresponding damping force in the selected stroke, so that the versatility of the present invention can be achieved.

In the second embodiment, the damper 116 adopts a specific embodiment of the self-generating damper device. Compared with the electromagnetic damper, the self-generating damper device has the advantage that it can be used in a place without power supply without the power line moving. Beautiful appearance.

In the technical solution of the present invention, the self-generating damper device and the electromagnetic damper are adopted, the difference is that the damper principle used is different, and some circuits are different, and other technical aspects are completely consistent, and the difference is described below.

In the circuit, the electromechanical program switch controls the selective on-off current output in the motion stroke, so that the operator has a corresponding damping force in the selected stroke, and the unselected stroke does not have the damping force.
