[0004] The present application provides a switching mechanism and a switching system, which can reduce the possibility of damage to the shell during the action of the switching mechanism.

[0005] In a first aspect, the present application provides a switching mechanism, comprising a shell, a functional component and a driving motor.

[0006] The shell has an installation cavity inside, and the shell is provided with a driving hole communicating with the installation cavity, and the driving hole is provided with an installation sleeve. The functional component is arranged inside the installation cavity. The driving motor has a driving shaft, the driving shaft is arranged in the installation sleeve, and the driving shaft cooperates with the functional component.

[0007] In the embodiment of the present application, the installation sleeve is arranged between the driving hole and the driving shaft, which can reduce excessive friction caused by manufacturing errors, and can also uniformly distribute the force between the driving hole and the driving shaft, thereby reducing the possibility of damage to the shell when the switching mechanism acts.

[0008] Optionally, the shell comprises a first shell body and a second shell body arranged opposite along a first direction, and the first shell body and the second shell body are buckled to form the installation cavity. The driving electrode is located on a side of the second shell body away from the first shell body, and the driving hole is arranged on the second shell body.

[0009] At least one of the first shell body and the second shell body is a plastic part.

[0010] In this way, one of the first shell body and the second shell body which is a plastic part can be formed by using a mold in an injection molding manner, which is convenient for large-scale production, can improve production efficiency, and can also meet the molding of complex structures.

[0011] Optionally, the first shell is provided with a first through hole extending in the first direction. On the side of the second shell facing the first shell, the second shell is provided with a connecting post integrally formed with the second shell, and the connecting post is provided with a threaded hole extending in the first direction. The switching mechanism further comprises a fastener, which is arranged through the first through hole and the threaded hole and is screwed with the threaded hole.

[0012] By the above arrangement, the connecting post is integrally formed with the second shell, which makes the connecting post and the second shell be obtained synchronously in one time. In this way, the connection mode of the connecting post and the second shell can be simplified, and the number of parts of the switching mechanism can be reduced.

[0013] The first shell and the second shell can be connected by screwing the fastener, which facilitates the connection of the first shell and the second shell.

[0014] Optionally, in the case that the second shell is a plastic part, the second shell is provided with a second through hole, and the second through hole is provided with a mounting sleeve, and the threaded hole is arranged in the mounting sleeve.

[0015] In this way, when the fastener is arranged, the fastener can pass through the first through hole and be screwed with the threaded hole in the mounting sleeve, which can improve the connection strength between the first shell and the second shell when the second shell is a plastic part.

[0016] Optionally, the functional assembly comprises a transmission gear, a rotating disc and an output shaft.

[0017] During the rotation of the transmission gear, the rotating disc can drive the output shaft to rotate, and the elastic sleeve is used for buffering the acting force between the rotating disc and the output shaft.

[0018] By the above arrangement, the elastic sleeve can buffer the force applied by the rotating disc to the output shaft, reduce the impact of the rotating disc on the output shaft, and thus can reduce the possibility of deformation of the output shaft due to impact, and improve the reliability of the operation of the switching mechanism.

[0019] Optionally, the functional assembly further comprises a connecting rod and an energy storage part, and a clamping shaft is further arranged between the first shell and the second shell.

[0025] Optionally, the mounting shaft is sleeved with an elastic member, one end of the elastic member abuts against the surface of the second shell facing the first shell, and the other end of the elastic member abuts against the handle gear, so that the position of the handle gear can be adjusted when the mounting shaft is embedded in the mounting hole.

[0026] Through the above arrangement, the two ends of the elastic member can abut against the second shell and the handle gear respectively, and the elastic member can limit the handle gear to realize the installation of the handle gear.

[0027] Moreover, the arrangement of the elastic member makes the position of the handle gear adjustable, which facilitates the adjustment of the position of the handle gear when the handle gear and the transmission gear are misaligned.

Therefore, "in one embodiment" or "in an embodiment" appearing throughout the description does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0052] For example, Figure 1As shown, the embodiment of the present application provides a switching system, which comprises a switching body and the switching mechanism 100 of any one of the first aspect. The switching body has an off state and an on state, the functional assembly 20 is matched with the switching body, and the driving motor 30 is used to drive the switching body to switch between the off state and the on state.

[0053] In the switching system provided by the present application, the switching body can be matched with the switching mechanism 100, so that the switching body can be controlled by the switching mechanism 100 to switch states based on the action of the switching mechanism 100.

[0054] Specifically, the switching body can be matched with the functional assembly 20 in the switching mechanism 100. In this way, under the operation of the driving motor 30, the driving motor 30 can drive the functional assembly 20 to act, so that the functional assembly 20 can drive the switching body to switch states.

[0055] The switching body can be connected in a circuit to control the on-off of the circuit. When the switching body is in the off state, the switching body can disconnect the circuit in which it is located, and when the switching body is in the on state, the switching body can connect the circuit in which it is located.

[0056] It should be noted that in the embodiment of the present application, the switching body can be different devices, such as circuit breakers, contactors or relays, etc. The specific type of the switching body is not limited in the embodiment of the present application.

[0057] The switching mechanism 100 provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0058] Referring to Figure 1 and Figure 2 As shown, the present application provides a switching mechanism 100, which comprises a housing 10, a functional assembly 20 and a driving motor 30. The housing 10 has an installation cavity 101 inside, the housing 10 is provided with a driving hole 102 communicating with the installation cavity 101, and the installation sleeve 103 is arranged in the driving hole 102. The functional assembly 20 is arranged inside the installation cavity 101. The driving motor 30 has a driving shaft 31, the driving shaft 31 is arranged in the installation sleeve 103 and matched with the functional assembly 20.

[0059] In the embodiment of the present application, the switching mechanism 100 comprises a housing 10, a functional assembly 20 and a driving motor 30. The functional assembly 20 is the main component in the switching mechanism 100, which can be matched with the switching body to drive the switching body.

[0060] The shell 10 can provide a mounting position for the functional assembly 20 to ensure normal operation of the functional assembly 20. Moreover, the functional assembly 20 is arranged in the mounting cavity 101 inside the shell 10, and the shell 10 can protect the functional assembly 20, reducing the possibility of damage to the functional assembly 20 directly subjected to force when the switching mechanism 100 is subjected to external impact.

[0061] In the present application, the driving motor 30 can serve as a driving mechanism to drive the functional assembly 20.

[0062] Specifically, the shell 10 is further provided with a driving hole 102 in communication with the mounting cavity 101, and the driving shaft 31 of the driving motor 30 can extend into the mounting cavity 101 through the driving hole 102 and cooperate with the functional assembly 20. In this way, when the driving motor 30 operates, the driving motor 30 can drive the functional assembly 20 to act, realizing the switching of the state of the switch body.

[0063] In the present application, the driving hole 102 is provided with a mounting sleeve 103, so that the driving shaft 31 can be arranged in the mounting sleeve 103 to extend into the mounting cavity 101 through the driving hole 102.

[0064] The mounting sleeve 103 is arranged on one side of the driving hole 102, and the driving shaft 31 is arranged in the mounting sleeve 103. In this way, the driving shaft 31 can be separated from the hole wall of the driving hole 102, reducing the possibility of excessive friction between the driving shaft 31 and the hole wall of the driving hole 102 due to manufacturing errors or burrs on the hole wall of the driving hole 102, which can cause damage to the driving hole 102 or the driving shaft 31.

[0065] On the other hand, the mounting sleeve 103 can uniformly distribute the force output by the driving shaft 31, so that when the driving motor 30 operates, the driving shaft 31 can uniformly act on the hole wall of the driving hole 102, preventing the possibility of damage to the hole wall of the driving hole 102 due to excessive local force.

[0066] In summary, the mounting sleeve 103 is arranged between the driving hole 102 and the driving shaft 31, which can reduce excessive friction caused by manufacturing errors and also can uniformly distribute the force between the driving hole 102 and the driving shaft 31, reducing the possibility of damage to the shell 10 when the switching mechanism 100 operates.

[0067] It should be noted that when the mounting sleeve 103 is arranged, the mounting sleeve 103 can be in interference fit with the driving hole 102. In this way, the mounting sleeve 103 is relatively fixed with the driving hole 102, and when the driving motor 30 operates to rotate the driving shaft 31, the driving shaft 31 can rotate relative to the mounting sleeve 103, while the mounting sleeve 103 is stationary relative to the driving hole 102.

[0068] In this way, the installation of the sleeve 103 is more stable, and the possibility of loosening and displacement of the sleeve 103 is reduced, so that the installation of the drive shaft 31 and the cooperation between the drive shaft 31 and the functional assembly 20 are more reliable.

[0069] In some embodiments, as shown in Figure 1 The housing 10 includes a first shell 11 and a second shell 12 arranged opposite along the first direction X, and the first shell 11 and the second shell 12 are buckled to form the installation cavity 101.

[0070] At this time, the functional assembly 20 can be arranged between the first shell 11 and the second shell 12, and the first shell 11 and the second shell 12 can protect the functional assembly 20 inside.

[0071] Referring to Figure 2 The drive motor 30 is located on the side of the second shell 12 away from the first shell 11, and the drive hole 102 is arranged on the second shell 12.

[0072] That is, the drive motor 30 is arranged outside the installation cavity 101 and on the side of the second shell 12 away from the first shell 11, so that the drive motor 30 can extend into the installation cavity 101 through the second shell 12 and cooperate with the functional assembly 20.

[0073] In this arrangement, the drive hole 102 can be arranged on the second shell 12 and penetrate the second shell 12, so that the drive hole 102 communicates with the installation cavity 101.

[0074] In the embodiments of the present application, at least one of the first shell 11 and the second shell 12 can be a plastic part.

[0075] In this way, one of the first shell 11 and the second shell 12 that is a plastic part can be formed by injection molding using a mold, which can reduce the production cost of the housing 10, facilitate mass production, and improve production efficiency.

[0076] On the other hand, the injection molding process can also meet the molding of complex structures. Therefore, one of the first shell 11 and the second shell 12 that is a plastic part can have other parts in addition to the plate-shaped part, such as a side wall and the like.

[0077] As a preferred manner, the first shell 11 and the second shell 12 can both be plastic parts.

[0078] At this time, the first shell 11 can have a first body and a first side wall connected to the first body, and the second shell 12 can include a second body and a second side wall connected to the second body.

[0079] The first body and the second body are both plate-shaped structures, the first side wall is located on a side of the first body facing the second body, and the second side wall is located on a side of the second body facing the first body.

[0080] In this way, the first shell 11 has a portion (i.e., the first side wall) extending toward the second shell 12, and the second shell 12 has a portion (i.e., the second side wall) extending toward the first shell 11.

[0081] In this way, the first body, the first side wall, the second side wall, and the second body can enclose the mounting cavity 101, and the first side wall and the second side wall can have a portion in contact when the first shell 11 and the second shell 12 are connected.

[0082] Through the above arrangement, the first shell 11 and the second shell 12 form the shell 10, which has a strong wrapping effect and good protection effect on the functional assembly 20 inside.

[0083] In the related art, the switching mechanism includes two metal sheets arranged opposite to each other, the two metal sheets are arranged at intervals to form a shell of the switching mechanism, and the main body portion of the switching mechanism can be mounted between the metal sheets.

[0084] Through the above arrangement of the related art, the shell 10 can only protect the main body portion in the distribution direction of the multiple metal sheets, and if other objects extend into the inside of the switching mechanism 100 from the gap between the two metal sheets, the main body portion can also be damaged.

[0085] Compared with the related art, the first shell 11 and the second shell 12 in the present application can protect the functional assembly 20 from different directions, which can improve the protection effect on the functional assembly 20.

[0086] Of course, only one of the first shell 11 and the second shell 12 can be a plastic piece, and the present application does not make specific limitations in this regard.

[0087] It should be noted that the material of the one plastic piece among the first shell 11 and the second shell 12 can be Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), or Polyamide (PA), etc. The specific material of the first shell 11 and the second shell 12 is not limited in the embodiments of the present application.

[0088] When only one of the first shell 11 and the second shell 12 is a plastic piece, the one that is not a plastic piece among the first shell 11 and the second shell 12 can be made of stainless steel, aluminum, or aluminum alloy, etc., and the present application does not make specific limitations in this regard.

[0089] In the embodiments of the present application, as shown in Figure 3 The first shell 11 and the second shell 12 can be connected through the fastener 13.

[0090] Specifically, in combination with Figure 1 and Figure 3 The first shell 11 is provided with a first through hole 111 extending along the first direction X. On the side of the second shell 12 facing the first shell 11, the second shell 12 is provided with a connecting column 121 integrally formed with the second shell 12, and the connecting column 121 is provided with a threaded hole extending along the first direction X. The fastener 13 is arranged in the first through hole 111 and the threaded hole, and is screwed with the threaded hole.

[0091] That is, the first shell 11 is provided with the first through hole 111, and the second shell 12 is provided with the threaded hole, so that the fastener 13 can be arranged in the first through hole 111 and the threaded hole, thereby achieving the connection of the first shell 11 and the second shell 12.

[0092] In this way, the first shell 11 and the second shell 12 can be connected in a threaded connection manner, which simplifies the connection difficulty and improves the connection strength.

[0093] The connecting column 121 is integrally formed with the second shell 12, which makes the connecting column 121 and the second shell 12 be obtained synchronously in one time. In this way, the connection mode of the connecting column 121 and the second shell 12 can be simplified, and the number of parts of the switching mechanism 100 can be reduced.

[0094] In the present application, in the case that the first shell 11 includes a first body and a first side wall, the first through hole 111 can be arranged on the first body. In the case that the second shell 12 includes a second body and a second side wall, the second through hole 122 can be arranged on the second body.

[0095] In order to make the effects of the present application clearer, the present application is described in detail in combination with related technologies.

[0096] In related technologies, the switching mechanism includes two sheet metal pieces arranged oppositely, the two sheet metal pieces are arranged at intervals, and the main body part of the switching mechanism can be installed between the two sheet metal pieces.

[0097] In order to make the two sheet metal pieces have a gap to accommodate the main body part of the switching mechanism, a support column is arranged between the two sheet metal pieces, and the two ends of the support column are connected with the two sheet metal pieces through screws or the like.

[0098] Generally, the thickness of the sheet metal piece is small, so in this way, the connection part of the sheet metal piece and the support column is only in the thickness direction of the sheet metal piece, which will limit the connection strength of the sheet metal piece and the support column.

[0099] In order to make the distance between each part of the sheet metal part consistent, the support column between the sheet metal parts is generally multiple. For example, four support columns are arranged at the four corners of the square sheet metal part.

[0100] In the present application, the second shell 12 is connected with a connecting column 121 extending along the first direction X. In this way, when the fastener 13 is arranged, the connection between the fastener 13 and the second shell 12 is not limited to the position of the wall thickness of the second shell 12, but can extend along the length direction of the connecting column 121, so that the connection position between the fastener 13 and the second shell 12 is more. In this way, the connection strength between the first shell 11 and the second shell 12 can be improved.

[0101] In the case where the first shell 11 includes a first body and a first side wall, and the second shell 12 includes a second body and a second side wall, the first side wall and the second side wall can be abutted to ensure that there is a gap between the first body and the second body, thereby forming a mounting cavity 101 for mounting the functional assembly 20.

[0102] In this way, compared with the related art, the switching mechanism 100 provided in the present application can also avoid the additional arrangement of the support column between the first shell 11 and the second shell 12, thereby reducing the number of parts of the switching mechanism 100 and facilitating the assembly of the switching mechanism 100.

[0103] It should be noted that the fastener 13 can be a threaded connecting piece such as a screw, a screw, a stud, etc.

[0104] In addition, as shown in Figure 2 and Figure 3 , the side of the first shell 11 facing the second shell 12 can also be provided with a connecting protrusion 19 similar to the connecting column 121. The first through hole 111 can penetrate the connecting protrusion 19 to improve the connection strength between the first shell 11 and the fastener 13.

[0105] In some embodiments, as shown in Figure 3 and Figure 4 , in the case where the second shell 12 is a plastic part, the second shell 12 is provided with a second through hole 122, and a mounting sleeve 123 is arranged in the second through hole 122, and a threaded hole can be arranged inside the mounting sleeve 123.

[0106] Compared with metal materials, the strength and toughness of plastic parts are slightly insufficient. In the case where the second shell 12 is a plastic part, the strength of the internal thread of the threaded hole in the second shell 12 also decreases. In this way, when the first shell 11 and the second shell 12 are connected by the fastener 13, there is a possibility of connection failure.

[0107] In order to improve the connection strength between the first shell 11 and the second shell 12 when the second shell 12 is made of plastic, a mounting sleeve 123 can be arranged in the second through hole 122. In this way, when the fastener 13 is arranged, the fastener 13 can pass through the first through hole 111 and be screwed into the threaded hole in the mounting sleeve 123.

[0108] The material of the mounting sleeve 123 can be metal, so that the strength of the thread in the threaded hole in the mounting sleeve 123 can be improved, and the connection strength between the fastener 13 and the second shell 12 can be improved.

[0109] It should be noted that in order to facilitate the arrangement of the mounting sleeve 123, the mounting sleeve 123 can be arranged as a pre-embedded part in the mold when the second shell 12 is manufactured, and then injection molding is performed to form the second shell 12 with the mounting sleeve 123 embedded inside.

[0110] Of course, the mounting sleeve 123 can also be arranged in other ways. For example, the mounting sleeve 123 can be arranged in an interference fit manner inside the second through hole 122 after the second shell 12 is formed.

[0111] Of course, in the above description, only some connection modes of the first shell 11 and the second shell 12 are shown, and the first shell 11 and the second shell 12 in the present application can also be connected in other ways, such as bonding, welding or riveting, etc. The specific connection mode of the first shell 11 and the second shell 12 is not limited in the embodiments of the present application.

[0112] In addition, the driving motor 30 is connected to the side of the second shell 12 away from the first shell 11, and is generally connected by a threaded part such as a screw.

[0113] In the case where the second shell 12 is made of plastic, in order to improve the connection strength between the driving motor 30 and the second shell 12, a sleeve 32 similar to the mounting sleeve 123 can also be arranged at the position on the second shell 12 where the driving motor 30 is connected, as shown in Figure 2 .

[0114] It should be further noted that the materials of the mounting sleeve 123 and the sleeve 32 can be metals such as brass, cast iron or zinc that have good wear resistance, and the specific materials of the mounting sleeve 123 and the sleeve 32 are not limited in the embodiments of the present application.

[0115] In some embodiments, as shown in Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the functional assembly 20 can include a transmission gear 21, a rotating disc 22 and an output shaft 23. The transmission gear 21 is matched with the driving shaft 31, and the driving shaft 31 can drive the transmission gear 21 to rotate under the operation of the driving motor 30. The rotating disc 22 is located on the side of the transmission gear 21 facing the first shell 11 and is matched with the transmission gear 21. The rotating disc 22 is provided with an assembly hole 221, and an elastic sleeve 222 is embedded in the assembly hole 221. The output shaft 23 is sleeved on the elastic sleeve 222.

[0116] During the rotation of the transmission gear 21, the rotating disc 22 can drive the output shaft 23 to rotate, and the elastic sleeve 222 is used to buffer the acting force between the rotating disc 22 and the output shaft 23.

[0117] The functional assembly 20 specifically includes the transmission gear 21, the rotating disc 22 and the output shaft 23. The transmission gear 21 can be matched with the driving shaft 31 of the driving motor 30 and can rotate under the action of the driving motor 30.

[0118] The rotating disc 22 is matched with the transmission gear 21, and can also rotate during the rotation of the transmission gear 21.

[0119] The rotating disc 22 is located on the side close to the first shell 11, and the output shaft 23 can extend into the mounting cavity 101 through the first shell 11 and be matched with the rotating disc 22. In this way, under the rotation of the rotating disc 22, the rotating disc 22 can drive the output shaft 23 to rotate, so as to transmit the action of the functional assembly 20 to the outside of the switching mechanism 100.

[0120] As shown in Figure 3 , Figure 5 and Figure 6 , the first shell 11 can be provided with an output hole 18. The output shaft 23 can first extend out of the shell 10 through the output hole 18 to be matched with the switch body. Thus, under the rotation of the output shaft 23, the output shaft 23 can drive the switch body to realize the switching of the state of the switch body.

[0121] In the embodiment of the application, the rotating disc 22 and the output shaft 23 can be matched through the elastic sleeve 222. In this way, under the rotation of the rotating disc 22, the rotating disc 22 can first apply force to the elastic sleeve 222, and then the elastic sleeve 222 can transmit the force to the output shaft 23, so that the output shaft 23 can rotate.

[0122] Through the above arrangement, the elastic sleeve 222 can buffer the force applied by the rotating disc 22 to the output shaft 23, reduce the impact of the rotating disc 22 on the output shaft 23, and thus can reduce the possibility of deformation of the output shaft 23 under impact, improve the reliability of the operation of the switching mechanism 100.

[0123] It should be noted that the elastic sleeve 222 can be made of natural rubber, styrene butadiene rubber, nitrile rubber, or the like. The specific material of the elastic sleeve 222 is not limited in the embodiments of the present application.

[0124] It should be further noted that the output shaft 23 can be a square shaft, a polygonal cross-section shaft, or a non-cylindrical shaft, so that the turntable 22 can drive the output shaft 23 to rotate.

[0125] In addition, the transmission gear 21 and the turntable 22 are moving parts in the switching mechanism 100 and need to withstand a large force. In order to reduce the possibility of damage to the transmission gear 21 and the turntable 22, the transmission gear 21 and the turntable 22 can be metal parts.

[0126] In addition, when the first housing 11 and the second housing 12 are both plastic parts, and the first housing 11 includes a first main body and a first side wall, and the second housing 12 includes a second main body and a second side wall, the length of the first side wall and the length of the second side wall can be small, so as to reduce the depth of the first housing 11 and the second housing 12.

[0127] In this way, the first side wall and the second side wall made of plastic material are less likely to deform, which can avoid interference between the shell 10 and the structure inside the mounting cavity 101, and even affect the movement. Moreover, it is also conducive to the miniaturization of the switching mechanism 100.

[0128] The length of the first side wall is the distance between the two ends of the first side wall in the first direction X. The length of the second side wall is the distance between the two ends of the second side wall in the second direction.

[0129] In the embodiments of the present application, the reduction of the length of the first side wall and the length of the second side wall will inevitably reduce the size of the mounting cavity 101 in the first direction X.

[0130] In order to enable the transmission gear 21, the turntable 22 and other components to be installed, the thickness of the transmission gear 21 or the turntable 22 can be thinned.

[0131] As a preferred manner, the thickness of the turntable 22 can be thinned.

[0132] On the one hand, after the thickness of the turntable 22 is thinned, the turntable 22 can be easily punched to obtain the assembly hole 221.

[0133] On the other hand, in the related art, the thickness of the turntable 22 is relatively large, which is to reduce the stress concentration between the turntable 22 and the output shaft 23, and reduce the possibility of damage to the output shaft 23.

[0134] The elastic sleeve 222 is arranged between the rotating disc 22 and the output shaft 23, and can buffer the force between the rotating disc 22 and the output shaft 23, so as to reduce the possibility of damage of the output shaft 23. Therefore, even if the thickness of the rotating disc 22 is thinned, the use requirement can be met.

[0135] The thickness of the rotating disc 22 refers to the distance between the opposite ends of the rotating disc 22 in the first direction X. The thickness of the transmission gear 21 refers to the distance between the opposite ends of the transmission gear 21 in the first direction X.

[0136] Specifically, compared with the related art, the thickness of the rotating disc 22 can be thinned by 1-3 mm.

[0137] Of course, when the thickness of the rotating disc 22 is thinned, the thickness of the transmission gear 21 can also be thinned.

[0138] In some embodiments, as shown in Figure 1 , Figure 5 and Figure 7 , the functional assembly 20 further comprises a connecting rod 24 and an energy storage member 25, and a clamping shaft 14 is arranged between the first shell 11 and the second shell 12. The transmission gear 21 is provided with a first sliding groove 211, the rotating disc 22 is provided with a second sliding groove 223, one end of the connecting rod 24 is arranged on the clamping shaft 14, the other end of the connecting rod 24 is connected with a clamping rod 241, the clamping rod 241 is arranged in the first sliding groove 211 and the second sliding groove 223, and the energy storage member 25 is sleeved on the middle part of the connecting rod 24.

[0139] During the process that the driving motor 30 drives the transmission gear 21 to rotate, the energy storage member 25 can drive the rotating disc 22 to rotate, so that the rotating disc 22 drives the output shaft 23 to rotate.

[0140] In the present application, the transmission gear 21 and the rotating disc 22 can be matched by the connecting rod 24 and the energy storage member 25. The energy storage member 25 can be elongated or shortened to realize energy storage or energy release.

[0141] The clamping shaft 14 is arranged between the first shell 11 and the second shell 12, and the energy storage member 25 can be installed through the clamping shaft 14 and the connecting rod 24.

[0142] Specifically, one end of the connecting rod 24 is arranged on the clamping shaft 14, and the clamping rod 241 at the other end of the connecting rod 24 can be embedded in the transmission gear 21 and the rotating disc 22 through the first sliding groove 211 and the second sliding groove 223. The energy storage member 25 is sleeved on the connecting rod 24 and located between the clamping shaft 14 and the clamping rod 241.

[0143] Thus, when the transmission gear 21 rotates based on the operation of the driving motor 30, the slot wall of the first sliding groove 211 can force the connecting rod 24 through the clamping rod 241, so that the connecting rod 24 can move with the rotation of the transmission gear 21.

[0144] During the movement of the connecting rod 24, the connecting rod 24 first separates from one slot wall of the second sliding groove 223, and then contacts another slot wall of the second sliding groove 223 and pushes the second sliding groove 223, so that the rotating disc 22 can rotate and in turn drive the output shaft 23 to rotate.

[0145] In the embodiment of the present application, as shown in Figure 5 the number of the connecting rod 24, the energy storage member 25 and the clamping shaft 14 can all be multiple.

[0146] Thus, both sides of the rotating disc 22 can be matched with the transmission gear 21 through the connecting rod 24 and the energy storage member 25, improving the reliability of the matching of the transmission gear 21 and the rotating disc 22. Moreover, the energy storage members 25 on both sides can drive the rotating disc 22 in different directions, so that the rotating disc 22 can rotate in different directions.

[0147] At this time, the transmission gear 21 is provided with two first sliding grooves 211, and the rotating disc 22 is provided with two second sliding grooves 223. One clamping rod 241 is embedded in each of the first sliding groove 211 and the second sliding groove 223.

[0148] Here, taking the placement of the switching mechanism 100 in the Figure 5 orientation as an example, and combining Figure 7 the following will be described in detail.

[0149] The connecting rod 24, the energy storage member 25 and the clamping shaft 14 on the left side of the transmission gear 21 and the rotating disc 22 are matched, and the connecting rod 24, the energy storage member 25 and the clamping shaft 14 on the right side of the transmission gear 21 and the rotating disc 22 are also matched.

[0150] For the convenience of description, the connecting rod 24, the energy storage member 25 and the clamping shaft 14 on the left side are respectively referred to as the first connecting rod, the first energy storage member and the first clamping shaft. The first sliding groove 211 on the left side is referred to as the first sub-groove, and the second sliding groove on the left side is referred to as the second sub-groove.

[0151] In the clockwise direction, the first sub-groove has opposite first and second slot walls, and the second sub-groove has opposite third and fourth slot walls.

[0152] The connecting rod 24, the energy storage member 25 and the clamping shaft 14 on the right side are respectively referred to as the second connecting rod, the second energy storage member and the second clamping shaft.

[0153] In the case that the driving motor 30 rotates to drive the driving shaft 31 to rotate clockwise, the first sub-groove rotates clockwise, and the second groove wall exerts force on the clamping rod on the first connecting rod, so that the first energy storage member is compressed to store energy, while the clamping rod on the first connecting rod is separated from the fourth groove wall and slides along the second sub-groove.

[0154] When the first connecting rod rotates to the horizontal state, the first energy storage member is compressed to the limit state, and as the transmission gear 21 continues to rotate, the energy storage member 25 can be elongated to release energy. At this time, the clamping rod on the first connecting rod can exert force on the rotating disc 22 through the third groove wall, so that the rotating disc 22 can rotate, thereby driving the output shaft 23 to rotate.

[0155] In the above process, the second connecting rod can slide in the first sliding groove 211 and the second sliding groove 223 on the right side.

[0156] Similarly, in the case that the driving motor 30 rotates to drive the driving shaft 31 to rotate counterclockwise, the second energy storage member can first store energy, then release energy, and then drive the rotating disc 22 to rotate counterclockwise through the second connecting rod. For details, reference can be made to the description of the case that the driving shaft 31 rotates clockwise, and the embodiments of the present application will not be described herein.

[0157] In the process of driving the output shaft 23 to rotate by the driving shaft 31, the first connecting rod can rotate relative to the first clamping shaft, and the second connecting rod can rotate relative to the second clamping shaft.

[0158] In this process, the first clamping shaft and the second clamping shaft can also rotate, thereby causing friction between the first clamping shaft and the shell 10, or causing friction between the second clamping shaft and the shell 10. That is, during the operation of the switching mechanism 100, friction can also exist between the clamping shaft 14 and the shell 10.

[0159] In order to reduce the friction, the arrangement between the clamping shaft 14 and the shell 10 can also be improved.

[0160] That is, as shown in Figs. Figure 3 , Figure 5 and Figure 8 , the first shell 11 can be provided with a shaft sleeve 15, and one end of the clamping shaft 14 towards the first shell 11 is mounted in the shaft sleeve 15. In this way, the one end of the clamping shaft 14 towards the first shell 11 does not directly contact the first shell 11, but can be embedded in the shaft sleeve 15. When the clamping shaft 14 rotates, the clamping shaft 14 can rotate in the shaft sleeve 15, thereby reducing the friction with the first shell 11.

[0161] Alternatively, as shown in Figs. Figure 3 , Figure 4 and Figure 5As shown, the second shell 12 can be provided with a shaft sleeve 15, and one end of the clamping shaft 14 towards the second shell 12 is mounted on the shaft sleeve 15. In this way, the one end of the clamping shaft 14 towards the second shell 12 is not in direct contact with the second shell 12, but can be embedded in the shaft sleeve 15. When the clamping shaft 14 rotates, the clamping shaft 14 can rotate in the shaft sleeve 15, reducing the friction on the second shell 12.

[0162] As a preferred mode, the first shell 11 and the second shell 12 can each be provided with a shaft sleeve 15. In this way, both ends of the clamping shaft 14 can be embedded in the shaft sleeve 15, reducing the friction on the first shell 11 and the second shell 12.

[0163] In the case where the clamping shaft 14 includes a first clamping shaft and a second clamping shaft, a shaft sleeve 15 can be provided at the connection between the first clamping shaft and the shell 10, and a shaft sleeve 15 can also be provided at the connection between the second clamping shaft and the shell 10, which can better reduce the friction.

[0164] The shaft sleeve 15 can be a metal piece to reduce the friction of the clamping shaft 14 on the first shell 11 and / or the second shell 12.

[0165] It should be noted that the energy storage member 25 can be a spring or other hollow component made of elastic material. The specific type of the energy storage member 25 is not limited in the embodiments of the present application.

[0166] In some embodiments, as shown in Figure 1 、 Figure 2 、 Figure 4 and Figure 8 , the mounting cavity 101 can also be provided with a handle gear 40, the surface of the second shell 12 towards the first shell 11 is provided with a mounting shaft 124, the surface of the first shell 11 towards the second shell 12 is provided with a mounting column 112, and the mounting column 112 is provided with a mounting hole 113. The handle gear 40 is sleeved on the mounting shaft 124, the part of the mounting shaft 124 on the side of the handle gear 40 towards the first shell 11 is embedded in the mounting hole 113, and the handle gear 40 cooperates with the functional assembly 20.

[0167] Through the above arrangement, the handle gear 40 can also drive the functional assembly 20, so that the functional assembly 20 can drive the switch body under the action of the handle gear 40.

[0168] That is, in addition to the driving motor 30 which can directly drive the functional assembly 20, the handle gear 40 can also serve as a driving member to drive the functional assembly 20, which makes the switching mechanism 100 proposed in the present application have two different driving modes.

[0169] In this way, in the case that one of the driving modes is unavailable, for example, the connection between the driving motor 30 and the power supply is disconnected, the handle gear 40 can be used to drive the switching mechanism 100, and the influence of unexpected situations on the operation of the switching mechanism 100 can be reduced.

[0170] The handle gear 40 can be engaged with the functional assembly 20, for example, the handle gear 40 can be engaged with the transmission gear 21.

[0171] In the embodiments of the present application, the handle gear 40 can be installed on the mounting shaft 124 through the mounting column 112. Specifically, the handle gear 40 can be sleeved on the mounting shaft 124, and then the first housing 11 and the second housing 12 are arranged opposite to each other, so that the mounting shaft 124 can be inserted into the mounting hole 113 on the mounting column 112.

[0172] In some embodiments, the mounting shaft 124 can be a stepped shaft, and the diameter of the portion of the mounting shaft 124 close to the second housing 12 is larger, and the diameter of the portion of the mounting shaft 124 away from the second housing 12 is smaller.

[0173] In this way, when the handle gear 40 is installed, the side of the handle gear 40 facing the first housing 11 can be limited by the mounting column 112, and the side of the handle gear 40 facing the second housing 12 can be limited by the stepped position on the mounting shaft 124, so that the handle gear 40 has a determined position in the mounting cavity 101.

[0174] It should be noted that on the side where the handle gear 40 is arranged, the first housing 11 and the second housing 12 can have a gap therebetween, so that part of the handle gear 40 is exposed, as shown in Figure 1

[0175] In this way, the operation hole 41 can be arranged on the part of the handle gear 40. When the user needs to operate the switching mechanism 100 through the handle gear 40, a tool can be inserted into the operation hole 41, and the tool can be used to apply force to the handle gear 40, so that the handle gear 40 can drive the transmission gear 21 to rotate.

[0176] In some embodiments, as shown in Figure 2 to Figure 4 , and Figure 8 The mounting shaft 124 can be sleeved with the elastic member 114, one end of the elastic member 114 abuts against the surface of the second housing 12 facing the first housing 11, and the other end of the elastic member 114 abuts against the handle gear 40.

[0177] Through the above arrangement, the two ends of the elastic member 114 can abut against the second housing 12 and the handle gear 40 respectively, and the elastic member 114 can limit the handle gear 40 to achieve the installation of the handle gear 40.

[0178] ​The elastic member 114 can be in a compressed state. Thus, after the handle gear 40 is installed, the elastic member 114 has a pushing force on the handle gear 40, so that the handle gear 40 has a tendency to move close to the first housing 11. Thus, the handle gear 40 can be reliably abutted on the mounting column 112.

[0179] In addition, the arrangement of the elastic member 114 can also make the position of the handle gear 40 adjustable. Specifically, after the handle gear 40 is installed on the mounting shaft 124 and the mounting shaft 124 is embedded in the mounting hole 113, if the handle gear 40 fails to mesh with the transmission gear 21 or meshes incorrectly, the handle gear 40 can be pushed to slide towards the side close to the second housing 12 and compress the elastic member 114.

[0180] At this time, the handle gear 40 is in a movable state, and the handle gear 40 can be rotated on the mounting shaft 124 to adjust the position of the handle gear 40, so that the handle gear 40 can correctly mesh with the transmission gear 21.

[0181] It should be noted that in the embodiment of the present application, the elastic member 114 on the mounting shaft 124 can limit the handle gear 40 on the side of the handle gear 40 towards the second housing 12, and therefore, in the present application, the mounting shaft 124 is a light shaft.

[0182] It should also be noted that the elastic member 114 can be a hollow part made of a helical spring, a tower spring or other elastic material. The specific form of the elastic member 114 is not limited in the embodiment of the present application.

[0183] In some embodiments, as shown in Figure 2 , Figure 4 and Figure 8 , the first housing 11 has a first surface 115 facing away from the second housing 12, and the second housing 12 has a second surface 125 facing away from the first housing 11. One of the first surface 115 and the second surface 125 can be provided with the insertion tab 16, and the other of the first surface 115 and the second surface 125 is provided with the connecting block 17.

[0184] The switching mechanism 100 is used to be connected with a base, the base is provided with a insertion hole, the insertion tab 16 is used to be inserted in the insertion hole, and the connecting block 17 is used to fix the switching mechanism 100 to the base.

[0185] That is, the switching mechanism 100 can be fixed on the base through the first housing 11 and the second housing 12, so that the position of the switching mechanism 100 is fixed, so that the switching mechanism 100 acts to control the switch body to switch states.

[0186] In the embodiment of the present application, the first surface 115 can be provided with the insertion tab 16, and the second surface 125 can be provided with the connecting block 17. Alternatively, the second surface 125 can be provided with the insertion tab 16, and the first surface 115 can be provided with the connecting block 17.

[0187] In this way, when connecting the switching mechanism 100 and the base, the insertion tab 16 can be inserted into the insertion hole to position the switching mechanism 100, and then the connecting block 17 is connected with the base to fix the switching mechanism 100.

[0188] In this way, when connecting the switching mechanism 100 and the base, the insertion tab 16 can be inserted into the insertion hole to position the switching mechanism 100, and then the connecting block 17 is connected with the base to fix the switching mechanism 100.

[0189] It should be noted that, in the case that the first shell 11 and the second shell 12 are plastic parts, the insertion tab 16 and the connecting block 17 can be made synchronously during the molding process of the first shell 11 and the second shell 12, which can simplify the structure of the switching mechanism 100 and reduce the number of parts.

[0190] It should be further noted that the connecting block 17 and the base can be connected in a detachable manner such as threaded connection or clamping, so that the switching mechanism 100 can be detached from the base after use for the next use.

[0191] At this time, in order to improve the reliability of the connection between the connecting block 17 and the base, the connecting block 17 can be provided with a connecting sleeve 171, as shown in Figure 3 The connecting sleeve 171 can be made of metal material.

[0192] In the embodiment of the present application, the mounting sleeve 103 is arranged between the driving hole 102 and the driving shaft 31, which can reduce excessive friction caused by manufacturing errors, and evenly distribute the force between the driving hole 102 and the driving shaft 31, thereby reducing the possibility of damage to the housing 10 when the switching mechanism 100 is in action.

[0193] Finally, it should be noted that the above embodiments are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
