Technical Field

[0001] This utility model relates to the field of electrical technology, specifically to a rotating mechanism. Background Technology

[0002] For example, a Chinese invention patent, publication number CN100538949C, entitled "Switch Device," describes the effect of a handle rotating to the main shaft component to achieve a transmission connection through a rotating mechanism. However, the problem with this structure is that the opening angle is insufficient during the opening process, affecting the performance of connecting and disconnecting the circuit. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is how to improve the performance of connection and disconnection.

[0004] A rotating mechanism, mounted on a housing, includes:

[0005] A connecting rod that rotates relative to the housing;

[0006] A rotating shaft, wherein the rotating shaft is provided with a driving block;

[0007] A rotating component that rotates in conjunction with the rotating shaft, the rotating component being provided with a driving rib and a driving groove, and one end of the connecting rod being located on the rotation trajectory of the driving rib;

[0008] Energy storage component, wherein the energy storage component is connected to the rotating component;

[0009] An output component, which rotates relative to the housing, is provided with a mating part, a groove, and a protrusion. The mating part mates with the drive block, the protrusion mates with the drive groove, and the groove is located on the movement trajectory of the connecting rod.

[0010] In the first state, the rotating shaft rotates, causing the rotating component to rotate; the driving rib drives the connecting rod to rotate; the other end of the connecting rod moves into the groove; and the connecting rod drives the output component to rotate.

[0011] In the second state, the rotating shaft rotates, causing the rotating component to rotate. The driving block abuts against the mating part, causing the output component to rotate. When the protrusion rotates to abut against the driving groove, the driving groove causes the protrusion to rotate, and the groove causes the connecting rod to reset.

[0012] It also includes a fixing plate and a pin, the fixing plate being fitted to the housing, the pin passing through the connecting rod, and the fixing plate being connected to the housing.

[0013] The housing has a fixing groove on the side facing the connecting rod, the fixing plate is partially embedded in the fixing groove, and the remaining part of the fixing plate extends toward the connecting rod.

[0014] One of the connecting rod and the housing is provided with a pivot, and the other of the connecting rod and the housing is provided with a pivot hole that mates with the pivot.

[0015] The connecting rod includes a first rod portion, a connecting portion, and a second rod portion. The connecting portion connects the first rod portion and the second rod portion. The first rod portion cooperates with the driving rib, and the second rod portion cooperates with the groove. The first rod portion and the second rod portion are misaligned.

[0016] The output component is provided with a protrusion located in the extending direction of the groove sidewall.

[0017] The imaginary central axis of the output component is perpendicular to the imaginary central axis of the rotating shaft.

[0018] The housing has a through hole, the output component has a limiting rib, the output component extends to the outside through the through hole, and the limiting rib abuts against the inner wall of the housing.

[0019] The protrusion gradually decreases in size towards the outside.

[0020] The end of the protrusion is curved.

[0021] The technical solution of this utility model has the following advantages:

[0022] 1. This utility model provides a rotating mechanism. This structure, through the cooperation of the rotating component, the output component, and the connecting rod, forms a coordinated effect. While ensuring rapid opening of the main contact (the main circuit begins to open after the main spring passes its dead point), the connecting rod transmission achieves large-angle opening (angle increased to 90° or greater). The connecting rod is self-resetting; during the rotation from the open state to the closed state, the connecting rod can self-reset.

[0023] 2. The rotating mechanism provided by this utility model increases strength and ensures the stability of the connecting rod by cooperating with the housing through a fixed plate, allowing the connecting rod to rotate relative to the pin. Alternatively, the fit between the rotating shaft and the rotating shaft hole can also create the effect of the connecting rod rotating relative to the housing.

[0024] 3. The rotating mechanism provided by this utility model has a fixed groove that creates a positioning and fixing effect, making the fixing plate more convenient to install.

[0025] 4. The present invention provides a rotating mechanism in which the rotating shaft and the rotating shaft hole cooperate to form the effect of the connecting rod rotating relative to the housing.

[0026] 5. The rotating mechanism provided by this utility model has a staggered arrangement, which improves space utilization and better achieves the cooperation effect between the connecting rod and the output component.

[0027] 6. The rotating mechanism provided by this utility model has a protrusion that increases the contact area with the connecting rod, thereby achieving a better contact effect with the connecting rod.

[0028] 7. The rotating mechanism provided by this utility model has a limiting rib that creates a limiting effect, so that the output part can only rotate radially and cannot slide axially.

[0045] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0046] Example 1

[0047] This embodiment provides a rotating mechanism, as shown in the attached figure. Figures 1-9 As shown, it includes:

[0048] Link 11 rotates relative to housing 12.

[0049] The rotating shaft 13 is equipped with a driving block 131. The rotating shaft 13 also rotates relative to the housing 12. Here, the driving block 131 is located on the side wall at the lower end of the rotating shaft 13.

[0050] Rotating component 14 rotates in conjunction with rotating shaft 13. Specifically, rotating component 14 is fitted onto the lower end of rotating shaft 13, and rotating shaft 13 rotates in conjunction with rotating component 14. That is, during the rotation of rotating shaft 13, rotating shaft 13 will drive rotating component 14 to rotate. Rotating component 14 is provided with driving rib 141 and driving groove 142. One end of connecting rod 11 is located on the rotation trajectory of driving rib 141. Specifically, when rotating component 14 rotates, driving rib 141 also rotates. Driving rib 141 abuts against one end of connecting rod 11, driving rib 141 to move one end of connecting rod 11, causing the other end of connecting rod 11 to move, thus creating the rotation effect of connecting rod 11.

[0051] Energy storage component 15 is connected to rotating component 14. Here, energy storage component 15 consists of two tension springs, which are respectively connected to the side wall of rotating component 14. When rotating component 14 rotates, the two tension springs and rotating component 14 will form a dead point state. When the dead point is passed, rotating component 14 accelerates its rotation. Simply put, the two tension springs store energy in the early stage, and when the dead point is passed, the tension springs release energy and accelerate the rotation. This is the prior art, so it will not be described in detail in this embodiment.

[0052] Output component 16 rotates relative to housing 12. Output component 16 is provided with mating part 161, groove 162 and protrusion 163. The mating part 161 mates with drive block 131, the protrusion 163 mates with drive groove 142, and the groove 162 is located on the movement trajectory of connecting rod 11.

[0053] In the first state, specifically referring to the process of rotating from the closed state to the open state, the rotating shaft 13 rotates, driving the rotating component 14 to rotate. As the rotating component 14 rotates, the driving rib 141 also rotates. When the driving rib 141 abuts against the connecting rod 11, the rotating component 14 continues to rotate, achieving the effect of the driving rib 141 driving the connecting rod 11 to rotate. Here, the driving rib 141 engages with the lower end of the connecting rod 11, while the other end of the connecting rod 11 moves into the groove 162. This other end of the connecting rod 11 is also the upper end, engaging with the groove 162. The connecting rod 11 abuts against the side wall of the groove 162, achieving the effect of the connecting rod 11 driving the output component 16 to rotate. During this process, the dead point position can be adjusted according to actual needs.

[0054] In the second state, specifically referring to the process of rotating from the open state to the closed state, the rotating shaft 13 rotates, causing the rotating component 14 to rotate. At this time, there is no engagement between the driving rib 141 and the connecting rod 11. The driving block 131 abuts against the mating part 161, causing the output component 16 to rotate. As the output component 16 rotates, the protrusion 163 rotates to abut against the driving groove 142. The driving groove 142 then drives the protrusion 163 to rotate. At this point, the other side wall of the groove 162 engages with the upper end of the connecting rod 11, causing the connecting rod 11 to rotate, thus achieving the reset effect of the connecting rod 11. During this process, the dead point position can be adjusted according to actual needs.

[0055] This structure, through the cooperation of rotating component 14, output component 16, and connecting rod 11, forms a linkage effect. While ensuring rapid opening of the main contacts (the main circuit begins to open after the main spring passes its dead point), the transmission of connecting rod 11 achieves a large-angle opening (angle increased to 90° or greater; the angle can be adjusted according to actual needs to meet corresponding operational requirements; a larger angle refers to an angle greater than 90°). Connecting rod 11 is self-resetting; during the rotation from the open to the closed state, connecting rod 11 can self-reset. This structure increases the opening angle and improves the performance of connection and disconnection.

[0056] Specifically, as shown in the attached document Figures 2-3 As shown, the system also includes a fixing plate 17 and a pin 18. The fixing plate 17 is fitted to the housing 12. The fixing plate 17 can be fitted to the inner wall of the housing 12 or the outer wall of the housing 12. In this embodiment, the fixing plate 17 is fitted to the inner wall of the housing 12. The pin 18 passes through the connecting rod 11, the fixing plate 17, and connects to the housing 12. The cooperation between the fixing plate 17 and the housing 12 increases strength and ensures the stability of the connecting rod 11, allowing the connecting rod 11 to rotate relative to the pin 18. Alternatively, the fit between a rotating shaft and a rotating shaft hole can also create the effect of the connecting rod 11 rotating relative to the housing 12.

[0057] Specifically, as shown in the attached document Figures 2-3 As shown, the housing 12 has a fixing groove 121 on the side facing the connecting rod 11. Specifically, the side of the housing 12 facing the connecting rod 11 refers to the inner side of the housing 12. The fixing plate 17 is partially embedded in the fixing groove 121, and the rest of the fixing plate 17 extends towards the connecting rod 11. The fixing groove 121 provides a positioning and fixing effect, making the fixing plate 17 easier to install.

[0058] Specifically, one of the connecting rod 11 and the housing 12 is provided with a pivot, and the other of the connecting rod 11 and the housing 12 is provided with a pivot hole that mates with the pivot. The mating of the pivot and the pivot hole creates the effect of the connecting rod 11 rotating relative to the housing 12. When the connecting rod 11 is provided with a pivot, the housing 12 is provided with a pivot hole; conversely, when the connecting rod 11 is provided with a pivot hole, the housing 12 is provided with a pivot. Those skilled in the art can adjust this according to actual needs.

[0059] Specifically, as shown in the attached document Figures 2-7 As shown, the connecting rod 11 includes a first rod portion 111, a connecting portion 112, and a second rod portion 113. The connecting portion 112 connects the first rod portion 111 and the second rod portion 113. The first rod portion 111 engages with the drive rib 141, and the second rod portion 113 engages with the groove 162. The first rod portion 111 and the second rod portion 113 are offset, specifically, the first rod portion 111 is closer to the front inner wall of the housing 12, while the second rod portion 113 is farther away from the front inner wall of the housing 12 relative to the first rod portion 111. This offset design improves space utilization and better achieves the cooperation effect between the connecting rod 11 and the output component 16.

[0060] Specifically, the output component 16 is provided with a protrusion 164, which is located in the extending direction of the sidewall of the groove 162. The protrusion 164 increases the mating area with the connecting rod 11, thereby achieving a better mating effect with the connecting rod 11.

[0061] Specifically, the imaginary central axis of the output component 16 is perpendicular to the imaginary central axis of the rotation shaft 13. In this embodiment, the imaginary central axis of the output component 16 is located on the Y-axis, that is, the output component 16 rotates around the Y-axis, and the imaginary central axis of the rotation shaft 13 is located on the Z-axis, that is, the rotation shaft 13 rotates around the Z-axis.

[0062] Specifically, as shown in the attached document Figures 1-9 As shown, the housing 12 has a through hole 122, and the output component 16 has a limiting rib 165. Part of the output component 16 extends to the outside through the through hole 122, and the limiting rib 165 abuts against the inner wall of the housing 12. The setting of the limiting rib 165 forms a limiting effect, so that the output component 16 can only rotate radially and cannot slide axially.

[0063] Specifically, as shown in the attached document Figures 3-8 As shown, the protrusion 163 gradually tapers outwards. Here, the protrusion 163 extends outwards along the radial direction of the output member 16, forming a pointed effect to better achieve the effect of engagement drive.

[0064] Specifically, the end of protrusion 163 is an arc surface.

[0065] Specifically, a torsion spring is also provided between the rotating shaft 13 and the rotating component 14. The torsion spring also stores and releases energy, improving the rotation efficiency of the rotating component 14. This is also prior art, so it will not be described in detail in this embodiment.

[0066] Specifically, as shown in the attached document Figures 1-7 As shown, it also includes a handle 19, which is connected to the top of the rotating shaft 13 to form a linkage effect.

[0067] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
