Abstract
Description
Technical Field
[0001] The present invention relates to a mechanical operation assembly for a bistable relay and a bistable relay assembly. Background Art
[0002] In an electronic thermal protection relay, a bistable relay is required to switch signals. In the working state, the switching of the bistable relay is completed by electronic signal control. However, when the product needs to be tested for wiring, or when the product has tripped and needs to be manually reset, the operation of the bistable relay needs to be controlled by mechanical connection. Summary of the Invention
[0003] The present invention provides a mechanical operation assembly for a bistable relay, including: a bracket, which is installed on the bistable relay; an actuating mechanism, which is installed on the bracket and includes an actuating member and a first transmission member. The first transmission member is connected to the toggle of the bistable relay. The actuating member is configured to move the first transmission member when actuated, and then move the toggle of the bistable relay, so that the bistable relay switches from the first state to the second state; a reset mechanism, which is installed on the bracket and includes a reset member and a second transmission member. The second transmission member is in contact with the first transmission member. The reset member can move between an initial position and a reset position. In the initial position, the reset member is not in contact with the second transmission member. When the reset member moves from the initial position to the reset position, the reset member is configured to contact the second transmission member, so that the second transmission member moves accordingly, and then the first transmission member drives the toggle of the bistable relay to move, so that the bistable relay switches from the second state to the first state. After the reset member reaches the reset position, the reset member disengages from the contact with the second transmission member.
[0004] Advantageously, the actuating member can move between an initial position and an actuating position. In the initial position, the actuating member is not in contact with the first transmission member. When the actuating member moves from the initial position to the actuating position, the actuating member is configured to contact the first transmission member, so that the first transmission member drives the toggle of the bistable relay to move, so that the bistable relay switches from the first state to the second state.
[0005] Advantageously, the first transmission member is translatably installed on the bracket. The actuating member includes a first inclined surface, and the first transmission member includes a second inclined surface. When the actuating member moves from the initial position to the actuating position, the first inclined surface abuts against the second inclined surface and pushes the first transmission member along a first translation direction, so that the bistable relay switches from the first state to the second state.
[0006] Advantageously, the actuating mechanism further includes a first return spring, which is arranged between the actuating member and the bracket. After the actuating member moves from the initial position to the actuating position against the elastic force of the first return spring, the actuating member returns to its initial position by the elastic force of the first return spring.
[0007] Advantageously, the first transfer member further includes an indicating member. After the first transfer member translates horizontally to switch the bistable relay from the first state to the second state, the indicating member is exposed through a window in a housing that surrounds the bistable relay and the mechanical operating assembly, thereby indicating that the bistable relay is in the second state.
[0008] Advantageously, the reset member includes a first engaging member, and the second transfer member is rotatably mounted on a bracket and includes a second engaging member. When the reset member moves from the initial position to the reset position, the first engaging member abuts against the second engaging member and pushes the second transfer member to rotate in the first direction, causing the first transfer member to move in a second translation direction opposite to the first translation direction, resulting in the bistable relay switching from the second state to the first state.
[0009] Advantageously, the first engaging member includes a third inclined surface. When the reset member moves from the initial position to the reset position, the third inclined surface abuts against the second engaging member and pushes the second transfer member to rotate in the first direction.
[0010] Advantageously, the reset mechanism further includes a second reset spring disposed between the second transfer member and the bracket; and a third reset spring disposed between the reset member and the bracket. When the reset member moves from the initial position to the reset position against the elastic force of the third reset spring, the second transfer member rotates in the first direction against the elastic force of the second reset spring.
[0011] Advantageously, after the reset member reaches the reset position, the third inclined surface disengages from abutting against the second engaging member, and the second transfer member returns to its initial position under the action of the second reset spring.
[0012] Advantageously, the reset mechanism further includes a third reset spring disposed between the reset member and the bracket. After the reset member reaches the reset position, the reset member returns to its initial position through the third reset spring.
[0013] Advantageously, the first engaging member further includes a curved surface opposite to the third inclined surface. During the reset member returning to its initial position through the third reset spring, the second engaging member of the second transfer member moves along the curved surface to the initial position.
[0014] Advantageously, the first transfer member is rotatably mounted on a bracket. When the actuating member moves from the initial position to the actuating position, the actuating member abuts against the first transfer member, causing the first transfer member to rotate, thereby driving the bistable relay to switch from the first state to the second state.

[0024] Various embodiments of the present invention will be described in detail with reference to the accompanying drawings. Here, it should be noted that in the drawings, the same reference numerals are assigned to components that substantially have the same or similar structures and functions, and repeated descriptions thereof will be omitted. Unless otherwise specified, the terms "first direction", "second direction", "rotation direction", etc. in this specification are all described with reference to the drawings of the present invention. The term "sequentially including A, B, C, etc." only indicates the arrangement order of the included components A, B, C, etc., and does not exclude the possibility of including other components between A and B and / or between B and C. The description of "first" and its variants is only for distinguishing components and does not limit the scope of the present invention. Without departing from the scope of the present invention, "first component" can be written as "second component", etc.
[0025] The drawings in this specification are schematic diagrams, which assist in explaining the concept of the present invention and schematically show the shapes of various parts and their mutual relationships.
[0026] Next, with reference to Figures 1 to 14 , a preferred embodiment of the present invention will be described in detail.
[0027] As shown Figures 1 to 3 in the figure, the mechanical operating component for the bistable relay is mounted on the bistable relay. The bistable relay assembly includes a housing S that houses the bistable relay 2 and the mechanical operating component 1. The mechanical operating component 1 includes a bracket 11 mounted to the bistable relay, an actuating mechanism, and a reset mechanism.
[0028] The actuating mechanism includes an actuating member 12 and a first transmission member 13. The first transmission member 13 is connected to the toggle of the bistable relay. The actuating member moves between an initial position and an actuating position. In the initial position (as Figure 1 shown), the actuating member does not contact the first transmission member. In this embodiment, the first transmission member 13 is slidably mounted on the bracket such that when the actuating member moves from the initial position to the actuating position (as Figure 3 shown), the actuating member contacts the first transmission member and causes the first transmission member to translate, which drives the toggle of the bistable relay to move accordingly, causing the bistable relay to switch from the first state to the second state. The actuating member 12 has a first inclined surface 121, and the first transmission member 13 has a second inclined surface 131 corresponding to the first inclined surface. In this embodiment, when the actuating member moves downward, the first inclined surface 121 abuts against the second inclined surface 131, causing the first transmission member to move to the right, driving the toggle of the bistable relay to move, and causing the bistable relay to switch from the first state to the second state. The first transmission member 13 further includes an indicating member 132. After the first transmission member translates to the right to cause the bistable relay to switch from the first state to the second state, the indicating member 132 is exposed through a window H in the housing, as Figure 14 shown, so that it can be visually observed that the bistable relay is in the second state. The actuating mechanism further includes a first return spring 14, which is mounted between the actuating member and the bracket and is used to return the actuating member from the actuating position to the initial position.
[0029] As Figure 4 shown, the reset mechanism includes a reset member 15 and a second transmission member 16. The reset member is capable of moving between an initial position and a reset position. In the initial position, the reset member does not contact the second transmission member. In this embodiment, the second transmission member is located below the reset member, is rotatably mounted on the bracket, and contacts the first transmission member. When the reset member moves downward, it contacts the second transmission member and pushes the second transmission member to rotate clockwise, which pushes the first transmission member to move to the left, driving the toggle of the bistable relay to move, and causing the bistable relay to switch from the second state to the first state. In the initial positions of the actuating member and the reset member, the movements of the first transmission member and the second transmission member are not obstructed by the actuating member and the reset member. Therefore, the actuating member and the reset member do not interfere with using an electrical signal to control the state switching of the bistable relay.
[0030] The reset member 15 has a first mating member 151, which includes a third inclined surface 152 and a curved surface 153 opposite to the third inclined surface. The second transmission member includes a second mating member 161. When the reset member moves downward, the third inclined surface 151 contacts the second mating member 161 to push the second transmission member to rotate in the clockwise direction.
[0031] The operation process of the reset mechanism will be described below with reference to Figures 5 to 12 the following.
[0032] Figure 5 Fig. shows a perspective view of a bistable relay assembly according to the present invention, wherein the reset member of the reset mechanism is in the initial position. Figure 6 is a schematic diagram of the corresponding reset mechanism Figure 5 showing the positional relationship between the first mating member of the reset member and the second mating member of the second transmission member. It can be seen from the figure that in the initial position of the reset member, the second mating member is located below the first mating member.
[0033] As Figure 7 and Figure 8 shown, when the reset member is pressed downward, the third inclined surface of the first mating member abuts against the second mating member and pushes the second mating member (and thus the second transmission member) to rotate in the clockwise direction, which causes the first transmission member to move to the left, thereby driving the paddle of the bistable relay to move accordingly.
[0034] Continue to press the reset member downward to the reset position. As Figure 9 and Figure 10 shown, the third inclined surface disengages from abutting against the second mating member. At this time, the second transmission member can move freely without being obstructed by the reset member, so that the second transmission member disengages from contacting the first transmission member. A second return spring 17 is provided between the second transmission member and the bracket, and a third return spring 18 is provided between the reset member and the bracket. The reset member moves from the reset position towards the initial position under the action of the third return spring, and the second transmission member moves counterclockwise along the curved surface under the action of the second return spring. As Figure 11 and Figure 12 shown, thus the reset member returns to the initial position and the second transmission member returns to the initial position.
[0035] In the above embodiment, the first transmission member is in the form of a push rod, which can translate on the bracket. Alternatively, as Figure 13 shown, the first transmission member can be in the form of a rotating rod, which rotates when pushed by the actuating member, thereby driving the paddle of the bistable relay to move. Similarly, the second transmission member can also push the rotating rod to rotate, thereby driving the paddle of the bistable relay to move in the opposite direction. For clarity, only the first transmission member in the form of a rotating rod is shown in Figure 13 while other related components are omitted.
[0036] The mechanical operating component of the bistable relay according to the present invention has been described above. Through this mechanical operating component, the state switching of the bistable relay can be controlled. At the same time, during the entire cycle before and after the switching, it does not affect the control of the state switching of the bistable relay by the electrical signal, meeting the requirement of free tripping.
[0037] Moreover, the technical features disclosed above are not limited to the combinations with other disclosed features. Those skilled in the art can also make other combinations among the technical features according to the purpose of the invention, subject to achieving the purpose of the present invention.
