Description

Technical Field

[0001] The present invention relates to a chassis interlocking device for connecting a chassis vehicle and a circuit breaker, and a chassis vehicle. Background Technology

[0002] Most existing chassis interlocking devices restrict the rotation of the chassis's lead screw, thereby limiting the chassis's rocking-in and rocking-out operations. However, this interlocking method cannot prevent forced operation and may damage the chassis.

[0003] Therefore, there is a need for an interlocking device that can prevent forced operation of the chassis vehicle. Summary of the Invention

[0004] This invention proposes a chassis interlocking device that can switch a circuit breaker from a closed state to an open state and prevent forced operation when the circuit breaker contacts cannot be separated.

[0005] According to one aspect, the present invention provides a chassis interlocking device, including a push plate disposed on the chassis, the push plate being configured to move horizontally in response to pressing a button on the chassis to expose an operating hole on the chassis, thereby enabling the chassis to be rocked in and out. The chassis interlocking device further includes a connecting plate for connecting to the transmission mechanism of a circuit breaker and pivotally mounted to the housing, capable of pivoting between a first position and a second position with the transmission mechanism of the circuit breaker. In the closed position of the circuit breaker, the connecting plate... In the first position, the circuit breaker is in the open position, and the connecting plate is in the second position; the driving member is movably mounted to the housing and configured to move vertically under the movement of the push plate; the driven member is pivotally mounted to the housing and configured to rotate in a predetermined rotation direction under the movement of the driving member; the interlocking member is connected to the opening half-shaft of the circuit breaker and configured to move vertically under the rotation of the driven member, causing the opening half-shaft to perform a corresponding action, resulting in the transmission mechanism of the circuit breaker switching the circuit breaker from the closed position to the open position.

[0006] Advantageously, the chassis interlocking device further includes a blocking member, which is mounted to the drive member and has one end received in a first elongated hole in the housing, and is movable vertically within the first elongated hole along with the drive member.

[0007] Advantageously, when the circuit breaker contacts separate, the connecting plate rotates from the first position to the second position, and the blocking part of the connecting plate moves out of the movement path of the blocking member in the first elongated hole, without obstructing the blocking member, so that the push plate can move horizontally to expose the operating hole on the chassis.

[0008] Advantageously, when the circuit breaker contacts cannot be separated, the connecting plate cannot switch from the first position to the second position, thus remaining in the first position. This causes the blocking element of the connecting plate to be located in the movement path of the blocking element within the first elongated hole, blocking the blocking element. This, in turn, prevents the push plate from moving horizontally and does not expose the operating holes on the chassis.

[0009] Advantageously, the drive element includes: a frame; a drive wheel mounted to the frame and movable in a vertical direction by the movement of the push plate; and a movable member fixedly mounted to the frame through a second elongated hole in the housing, the movable member being movable within the second elongated hole.

[0010] Advantageously, the push plate has a first inclined surface, to which the drive wheel abuts, and when the push plate moves in the horizontal direction, the first inclined surface is configured to cause the drive wheel to move along the inclined surface and thus move in the vertical direction.

[0011] Advantageously, the movable member has a cover plate and a protrusion whose shape matches the shape of the second elongated slot and can be mounted to the frame through the second elongated slot, the width of which is greater than the width of the second elongated slot.

[0012] Advantageously, the driven member includes a first crank arm, a second crank arm, and a connecting rod connecting the first crank arm and the second crank arm. When the drive wheel moves vertically under the movement of the push plate, the drive wheel abuts against the first crank arm, causing the first crank arm to rotate in a predetermined rotation direction, thereby causing the second crank arm to also rotate in the predetermined rotation direction.

[0013] Advantageously, the drive element further includes a return spring configured to store energy as the first crank arm, connecting rod, and second crank arm rotate in a predetermined rotational direction, and to reset the first crank arm, connecting rod, and second crank arm after operation.

[0014] Advantageously, the second crank arm has a second inclined surface, which is configured to allow the interlocking member to move vertically along the second inclined surface when the second crank arm rotates in a predetermined rotation direction.

[0015] According to another aspect, the present invention provides a chassis vehicle including the above-described chassis vehicle interlocking device. Attached Figure Description

Detailed Implementation

[0023] Various embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that, in the drawings, the same reference numerals are assigned to components having substantially the same or similar structure and function, and repeated descriptions of them are omitted. The term "comprising A, B, C, etc." only indicates the order in which the included components A, B, C, etc., are arranged, and does not exclude the possibility of including other components between A and B and / or between B and C.

[0024] The accompanying drawings in this specification are schematic diagrams used to help illustrate the concept of the invention, and schematically show the shape of each part and their interrelationship.

[0025] Below, refer to Figures 1 to 6 The preferred embodiments of the present invention will be described in detail below.

[0026] Figure 1 The schematic diagram of the chassis interlocking device according to the present invention, installed on the chassis and the circuit breaker, shows the circuit breaker in the open position and the connecting plate in the second position. Figure 1 As shown, the chassis interlocking device includes a push plate 1 mounted on the chassis. When a button 2 on the chassis is pressed, the push plate 1 can move forward (i.e., towards the inside of the chassis) horizontally, thereby exposing an operating hole 3 on the chassis, through which the chassis can be rocked in and out. Exposing the operating hole via the button and push plate is well known to those skilled in the art, therefore the specific method will not be described in detail herein.

[0027] like Figure 2 , 3As shown in Figure 4, the chassis interlocking device also includes a connecting plate 8, which is connected to the transmission mechanism of the circuit breaker and pivotally mounted to the housing 5 of the chassis interlocking device. It can pivot between a first position and a second position along with the transmission mechanism of the circuit breaker. In the closed position of the circuit breaker, the connecting plate is in the first position (e.g., ...). Figure 5 As shown), in the open position of the circuit breaker, the connecting plate is in the second position (as shown). Figure 1 (As shown).

[0028] The chassis interlocking device also includes a drive member 4, which is mounted to the housing 5 and configured to move vertically under the movement of the push plate, specifically upwards in this embodiment. The drive member includes a frame 41, to which a drive wheel 42 is mounted. The drive wheel 42 is configured to abut against a first inclined surface 11 of the push plate 1. As the push plate moves inwards, the drive wheel 42 moves along the first inclined surface and is simultaneously pressed upwards by the first inclined surface. The drive member also includes a movable member 43, which can pass through a second elongated hole 52 on the housing 5 and be fixedly mounted to the frame 41, and can move vertically within the second elongated hole 52. The movable member 43 includes a cover plate 431 and a protrusion 432. The protrusion is shaped to match the shape of the second elongated hole and can pass through the second elongated hole to be mounted to the frame. The width of the cover plate is greater than the width of the second elongated hole to allow the movable member to move vertically within the second elongated hole.

[0029] The chassis interlocking device also includes a driven member 6 and an interlocking member 7, which are pivotally mounted to the housing 5 and are capable of rotating in a predetermined direction (e.g., from) the movement of the drive member 4. Figure 5 (When viewed from the side view, rotate clockwise). The rotation of the driven member 6 causes the interlocking member 7 to move vertically. The interlocking member 7 is connected to the circuit breaker's tripping half-shaft 9, causing the tripping half-shaft to perform a corresponding action. This causes the circuit breaker's transmission mechanism to operate accordingly, driving the connecting plate from the first position to the second position.

[0030] The driven member 6 includes a first crank arm 61, a second crank arm 63, and a connecting rod 62 connecting the first and second crank arms. When the drive wheel 42 moves upward, it abuts against the first crank arm 61, pushing the first crank arm 61 to pivot about the connecting rod as the central axis in a predetermined rotation direction, thereby pivoting the second crank arm 63 as well. The second crank arm 63 has a second inclined surface 631, which is configured such that when the second crank arm rotates in the predetermined direction, the interlocking member 7 moves along the second inclined surface and simultaneously moves upward.

[0031] The drive unit 4 also includes a return spring 44, which is configured to store energy when the first crank arm, the connecting rod and the second crank arm rotate in a predetermined rotation direction, and to reset the first crank arm, the connecting rod and the second crank arm after the operation is completed.

[0032] like Figure 4As shown, the chassis interlocking device also includes a blocking member 45, which is fixedly mounted to the frame 41 of the drive member 4, and one end is received in the first elongated hole 51 of the housing. This blocking member can move vertically along with the drive member. When the circuit breaker contacts cannot be separated (e.g., due to the contacts being welded together), the connecting plate 8 cannot switch from the first position to the second position, thus remaining in the first position, causing the movement of the blocking member 45 within the first elongated hole 51 to be blocked by the connecting plate 8 (e.g., ...). Figure 6 (As shown), this prevents the push plate from moving further horizontally and thus avoids exposing the operating holes on the chassis.

[0033] The operation process of the chassis interlocking device of the present invention is described below.

[0034] When the circuit breaker is removed Figure 5 The indicated closing position is switched to Figure 1 When the circuit breaker is in the open position as shown, pressing button 2 causes push plate 1 to move forward toward the paper, which in turn causes drive wheel 42 to move upward via the first inclined surface 11. This causes the first crank arm 61 and the second crank arm 63 to move clockwise. The second inclined surface 631 of the second crank arm causes interlocking member 7 to move upward, which in turn causes the open half-shaft to move accordingly, resulting in the circuit breaker's transmission mechanism moving accordingly, causing connecting plate 8 to... Figure 5 The first position in the middle pivots counterclockwise to Figure 1 The second position. During this process, although the blocking member 45 moves upward within the first elongated hole 51, due to the successful tripping of the circuit breaker, the connecting plate moves counterclockwise to the second position, and the blocking part 81 of the connecting plate pivots out of the moving path of the blocking member, so that the connecting plate will not abut against the blocking member 45.

[0035] In cases where the circuit breaker contacts cannot be separated, for example due to welding, pressing button 2 will still cause the push plate 1 to tend to move forward toward the paper. However, since the blocking part 81 of the connecting plate 8 is located on the movement path of the blocking member 45 within the first elongated hole, when the blocking member 45 moves upward to abut against the blocking part 81 (e.g. Figure 6 As shown in the figure, it cannot move upwards, which prevents the drive wheel from moving upwards, thus preventing the push plate 1 from moving further. Consequently, the operating hole 3 will not be exposed, and the chassis vehicle cannot be rocked in or out.

[0036] When the circuit breaker is in the closed state, the chassis interlocking device of this invention can switch the circuit breaker to the open state, simultaneously exposing the operating port for chassis roll-in / roll-out operations. When the circuit breaker contacts are in a welded state and have not separated, the interlocking device ensures that the chassis operating port is in a closed state, preventing chassis roll-in / roll-out operations, preventing forced operation, and ensuring personal safety.

[0037] The above description is merely an explanation of the present invention, enabling those skilled in the art to fully implement the solution, but it is not intended to limit the present invention. The technical features disclosed above are not limited to combinations of the disclosed features with other features; those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the objective of the present invention.
