[0002] At present, in order to solve the problem of arcing when a plug is inserted into or pulled out of an electrode socket, a switch mechanism is usually provided between the socket of the socket and the power circuit. The switch mechanism is configured so that when the plug is inserted, it first contacts the socket, and then drives a driving block (also called a push block) of the switch mechanism to move it horizontally, so that the switch mechanism switches from an open state to a closed state, thereby achieving the purpose of controlling the power on and off of the socket and avoiding arcing during the insertion or removal of the plug.

DETAILED DESCRIPTION
[0049] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0051] In the related art, the driving block has an inclined and planar driving surface, which makes the plug pin contact with the driving surface at a single point. On the one hand, the driving surface will be easily worn, resulting in a loss of driving stroke. On the other hand, the single-point contact will cause the driving point of the plug pin on the driving surface to be offset, thereby causing the force on the driving block to be offset, causing the driving stroke of the driving block to be deflected, which is not conducive to the precise driving of the driving block.
[0052] In view of the technical problems existing in the related art, the embodiment of the utility model provides a switch mechanism, as shown in the attached Figure 1 -Attached Figure 2 As shown, the switch mechanism includes: a housing 1, a drive block 2 located inside the housing 1, and a switch assembly 100. Figure 3 and Figure 4 As shown, the driving block 2 includes: a driving body 21, a groove 210 disposed on one side of the driving body 21, and a driving surface 211 formed by the inner wall of the groove 210. The driving body 21 is arranged in linkage with the switch assembly 100, as shown in the attached Figure 5 As shown, the driving surface 211 includes a middle contact surface 2110, a first side contact surface 2111 and a second side contact surface 2112 respectively located on both sides of the middle contact surface 2110. For example, the first side contact surface 2111 and the second side contact surface 2112 can be arranged symmetrically relative to the middle contact surface 2110.
[0053] In the embodiment of the utility model, the driving block 2 is configured to allow the driving component 001 to contact the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 at the same time to drive the driving block 2 to move, thereby driving the switch assembly 100 to switch between the on state and the off state.
[0054] The switch mechanism provided by the embodiment of the utility model is provided with a groove 210 on the driving body 21 of the driving block 2, and the driving surface 211 is formed by the inner wall of the groove 210. When the driving component 001 drives the driving block 2, the driving end of the driving component 001 enters the groove 210, and the driving end of the driving component 001 is in contact with the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 at the same time, so that the driving component 001 is in multi-point or even multi-faceted contact with the driving surface 211 during the driving process, thereby increasing the contact area. On the one hand, this is conducive to reducing the wear of the driving component 001 on the driving surface 211, thereby reducing the loss of the driving stroke. On the other hand, the first side contact surface 2111 and the second side contact surface 2112 are located on the middle contact surface 2110, so that the resultant force of the two driving forces applied by the driving component 001 to the first side contact surface 2111 and the second side contact surface 2112 is in the same direction as the force applied by the driving component 001 to the middle contact surface 2110. The three are combined to form a driving force and apply precise drive to the driving block 2, avoiding driving deviation and ensuring that the driving stroke of the driving block 2 is always on the desired driving path.
[0055] In the embodiment of the utility model, the first side contact surface 2111 and the second side contact surface 2112 are respectively located on both sides of the central axis of the middle contact surface 2110, wherein the projection of the central axis of the middle contact surface 2110 of the driving block 2 on the driving body 21 is located on the central axis of the driving body 21, so that the driving component 001 applies the main driving force to the middle contact surface 2110. The projections of the first side contact surface 2111 and the second side contact surface 2112 on the driving body 21 are symmetrically located on both sides of the central axis of the driving body 21, and the structures of the two are the same, and the driving component 001 applies auxiliary driving force to both the first side contact surface 2111 and the second side contact surface 2112.
[0056] Since the driving end of the driving component 001 is in contact with the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 at the same time, this means that the driving component 001 is in at least three-point contact with the driving surface 211. Further, in the embodiment of the utility model, at least one of the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 is configured to be in multi-point contact or surface contact with the driving end of the driving component 001.
[0057] For example, the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 are in multi-point contact or surface contact with the driving end of the driving component 001, or the middle contact surface 2110 is in multi-point contact or surface contact with the driving end of the driving component 001, while the first side contact surface 2111 and the second side contact surface 2112 can be in single-point contact, multi-point contact or surface contact with the driving end of the driving component 001. The above arrangement is conducive to further increasing the contact area between the driving surface 211 and the driving component 001, reducing the wear of the driving surface 211, and facilitating the precise driving of the driving block 2.
[0058] In some examples, the middle contact surface 2110, the first side contact surface 2111, and the second side contact surface 2112 are all arranged obliquely relative to the driving direction of the driving component 001, and the middle contact surface 2110, the first side contact surface 2111, and the second side contact surface 2112 are each independently a plane or an arc surface. For example, the middle contact surface 2110, the first side contact surface 2111, and the second side contact surface 2112 can all be planes, or arc surfaces; the middle contact surface 2110 can also be an arc surface, while the first side contact surface 2111 and the second side contact surface 2112 can both be planes; the middle contact surface 2110 can also be a plane, while the first side contact surface 2111 and the second side contact surface 2112 can both be arc surfaces.
[0059] By arranging the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 at an angle relative to the driving direction of the driving component 001, the driving force along the driving direction of the driving component 001 can be converted into a driving force that causes the driving block 2 to move in a translational manner, thereby realizing the redirection of the driving force. For example, the driving component 001 is driven in a vertical direction, and finally the driving block 2 moves in a horizontal direction.
[0060] As described above, the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 are each independently a plane or an arc surface. In order to improve the driving efficiency, the driving surface of the driving end of the driving component 001 can also be correspondingly designed as a plane or an arc surface to achieve a surface-to-surface contact effect.
[0061] In some examples, such as the attached Figure 5 As shown, the middle contact surface 2110 , the first side contact surface 2111 and the second side contact surface 2112 are all arc surfaces and any two adjacent ones are smoothly connected, so that the driving surface 211 is an arc surface.
[0062] For this example, the driving surface of the driving end of the driving component 001 can be set to an arc surface that matches the driving surface 211, so that the driving end of the driving component 001 can be in surface contact with the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112, thereby improving the driving efficiency and driving accuracy.
[0063] In other examples, such as the Figure 6 As shown, the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112 are all planes and are connected at an angle between any two adjacent planes, so that the driving surface 211 is a bent surface. For example, the angle between the middle contact surface 2110 and the first side contact surface 2111 is the same as the angle between the middle contact surface 2110 and the second side contact surface 2112, and the angle can be a right angle or an acute angle, for example, a right angle.
[0064] For this example, the driving surface of the driving end of the driving component 001 can be set to a plane that matches the driving surface 211, so that the driving end of the driving component 001 can be in surface contact with the middle contact surface 2110, the first side contact surface 2111 and the second side contact surface 2112, thereby improving the driving efficiency and driving accuracy.
[0065] As described above, the driving component 001 is driven in the vertical direction, so that the driving block 2 moves in the horizontal direction. In this case, the groove 210 is arranged on one side of the driving body 21, and the wall constituting the groove 210 has a notch along the surface perpendicular to the driving direction of the driving component 001, so that the groove 210 is an open groove cavity, so that the partial surface of the driving end of the driving component 001 is in contact with the driving surface 211. On the one hand, the driving surface 211 provided by the groove 210 is driven based on the partial surface of the driving end of the driving component 001, and the driving block 2 moves in the direction of one side of the driving component 001 without being interfered by the driving component 001. Moreover, it can also avoid the formation of undesirable friction resistance between the non-driving part of the driving component 001 and the groove 210, thereby improving the driving efficiency. In addition, the open design of the groove 210 is also conducive to simplifying its preparation process.
[0066] In the embodiment of the utility model, the switch component 100 involved can be designed into various types, as long as it can be linked by the driving block 2 to achieve the switching between the on state and the off state. For example, when the switch component 100 is used in the socket, it can control the on and off of the socket. The on state of the switch component 100 is the power-on state, and the off state of the switch component 100 is the power-off state.
[0067] The structure of the switch assembly 100 involved in the socket is described below as an example. Figure 1-Figure 2As shown, the switch assembly 100 includes a swing block 3, an elastic member 4, a moving contact piece 5 and a stationary contact piece 6. The swing block 3 is rotatably connected to the housing 1, a portion of the swing block 3 is located between the drive block 2 and the elastic member 4, and the moving contact piece 5 is connected to the swing block 3 and corresponds to the stationary contact piece 6; the drive block 2 can be driven to move from the first position to the second position, and drives the swing block 3 to swing the moving contact piece 5 to contact the stationary contact piece 6. When the drive block 2 is in the first position, the drive block 2 is separated from the swing block 3 and the elastic member 4 is against the swing block 3; when the drive block 2 is in the second position, the drive block 2 is against the swing block 3 and the elastic member 4 is separated from the swing block 3.
[0068] By improving the assembly method between the drive block 2, the swing block 3 and the elastic member 4, when the swing block 3 is driven forward by the drive block 2, the elastic member 4 will not exert a reverse force on the swing block 3, and when the swing block 3 is driven reversely by the elastic member 4, the drive block 2 will not exert a positive force on the swing block 3, thereby significantly improving the movement speed of the swing block 3 and achieving a better instantaneous on-off effect of the switch mechanism, which is conducive to curbing or even avoiding the arcing when the moving contact piece 5 and the static contact piece 6 in the switch mechanism contact or separate. In addition, the switch mechanism provided by the embodiment of the present invention also has the advantages of a small number of parts, a small size, and strong operational reliability. Based on the constituent components of the switch mechanism of the embodiment of the utility model, it can be seen that the number of parts contained is small, which is conducive to simplifying the structure of the switch mechanism and enhancing its operational reliability.
[0069] Further integration Figure 3 As shown, the swing block 3 includes: a swing body 31 rotatably connected to the housing 1, and a swing arm 32 connected to the swing body 31. The driving block 2 includes: a driving body 21 located on the first side of the swing arm 32, and a connecting arm 22 connected to the driving body 21 and movably passing through the swing arm 32. The elastic member 4 is located on the second side of the swing arm 32, and the two ends of the elastic member 4 are respectively connected to the housing 1 and the connecting arm 22; the moving contact piece 5 is connected to the swing body 31 and corresponds to the static contact piece 6, and the driving block 2 can be driven to move from the first position to the second position, and drive the swing block 3 to make the moving contact piece 5 swing to contact with the static contact piece 6.
[0070] Combination Figure 8 It can be seen that when the driving block 2 is in the first position, the driving body 21 is separated from the first side of the swing arm 32 and the elastic member 4 is against the second side of the swing arm 32; Figure 7 It can be seen that when the driving block 2 is in the second position, the driving body 21 abuts against the first side of the swing arm 32 and the elastic member 4 is separated from the second side of the swing arm 32 .
[0071] The switch mechanism provided in the embodiment of the utility model can be applied to the socket, and connected between the power circuit and the socket socket assembly. Taking the socket as a DC socket as an example, the switch mechanism can be connected between the power circuit (for example, the positive pole incoming terminal) and the positive pole socket of the socket, and accordingly, the static contact piece 6 of the switch mechanism is electrically connected to the positive pole incoming terminal of the power circuit, and the moving contact piece 5 is electrically connected to the positive pole socket of the socket. Taking the socket as an AC socket as an example, the switch mechanism can be connected between the power circuit (for example, the L pole incoming terminal) and the L pole socket of the socket, and accordingly, the static contact piece 6 of the switch mechanism is electrically connected to the L pole incoming terminal of the power circuit, and the moving contact piece 5 is electrically connected to the L pole socket of the socket. Of course, it is also possible for the switch mechanism to be electrically connected to other sockets of the socket.
[0072] When the switch mechanism is assembled in the socket, the switch mechanism can be arranged on the side of the socket away from the socket panel, so that during the insertion of the plug pin, the plug pin can first contact the socket, and as the plug pin continues to be inserted, the plug pin drives the drive block 2 of the switch mechanism to switch the switch mechanism from the open state to the closed state. For the plug pin mentioned here, the plug pin can be a ground pin in the plug, or can be any one of the positive pin or the negative pin (corresponding to the DC socket), or can be any one of the L-pole pin or the N-pole pin (corresponding to the AC socket).
[0073] As attached Fig. 9 As shown, the switch mechanism involved in the embodiment of the utility model, its movable contact piece 5 is separated from the static contact piece 6 in the normal state without external force driving, the switch mechanism is in the disconnected state, and the socket is not charged. When the plug pin is inserted into the socket, the plug pin as the driving component 001 can first contact the socket that is not charged, and then drive the driving block 2 to move from the first position to the second position, and the moving driving block 2 then drives the swing block 3 to rotate, and the rotating swing block 3 makes the movable contact piece 5 swing to contact with the static contact piece 6, so that the switch mechanism switches to the closed state and the socket is charged. On the contrary, when the plug pin is pulled out of the socket, the movable contact piece 5 and the static contact piece 6 are separated first, so that the switch mechanism switches to the disconnected state and the socket is not charged, and then the plug pin is separated from the socket. Therefore, when the switch mechanism is connected to the circuit where the socket is located, it can avoid arcing during the insertion or removal of the plug pin.
[0074] As for the switch mechanism itself, it includes: a housing 1, a driving block 2 located inside the housing 1, a swing block 3, an elastic member 4, a moving contact piece 5 and a stationary contact piece 6. The swing block 3 is rotatably connected to the housing 1 and connected to the moving contact piece 5 through a swing body 31, so as to realize the swinging function of the swing block 3 and the moving contact piece 5. The swing block 3 is respectively connected to the driving block 2 and the elastic member 4 through a swing arm 32. On the one hand, under the driving action of the driving component 001, for example, the plug pin, the driving block 2 acts on the swing block 3 through the swing arm 32 to make it swing, thereby making the moving contact piece 5 move to contact with the stationary contact piece 6, so that the switch mechanism switches to the closed state. On the other hand, when the plug pin is pulled out, the elastic member 4 elastically resets, and the elastic member 4 acts on the swing block 3 to make it swing in the opposite direction, thereby making the moving contact piece 5 move to separate from the stationary contact piece 6, so that the switch mechanism switches to the open state.
[0075] In particular, the embodiment of the utility model makes the following improvements to the assembly method between the drive block 2, the swing arm 32 and the elastic member 4: when the drive block 2 is in the first position, the drive body 21 is separated from the first side of the swing arm 32 and the elastic member 4 is against the second side of the swing arm 32. When the drive block 2 is in the second position, the drive body 21 is against the first side of the swing arm 32 and the elastic member 4 is separated from the second side of the swing arm 32. This arrangement can significantly improve the instantaneous effect of the switch mechanism for the following reasons.
[0076] Taking the application of the switch mechanism to the socket as an example, when the plug pin is inserted, it can drive the switch mechanism to switch from the open state to the closed state. However, when the plug pin is pulled out, it cannot drive the switch mechanism to switch from the closed state to the open state. Therefore, an elastic member 4 is required to drive the disconnection process of the driving switch.
[0077] In view of the above technical background, the current common solution is to arrange a forward driving member (for example, the driving block 2 of the swing block 3 involved in the present application) and a reverse driving member (for example, the elastic member 4 involved in the present application) on opposite sides of the transmission member in the switch mechanism (for example, the swing arm 32 of the swing block 3 involved in the present application), respectively, and the forward driving member and the reverse driving member are respectively in contact with the opposite sides of the transmission member, so that the forward driving member drives the transmission member forward to switch the switch mechanism to the closed state, and at the same time, the reverse driving member with elastic characteristics is compressed, so that the reverse driving member can drive the transmission member in the reverse direction to switch the switch mechanism to the open state. However, since the two sides of the transmission member bear the forward driving force from the forward driving member and the reverse driving force from the reverse driving member respectively, the forward movement and reverse movement speeds of the transmission member are relatively slow, which is obviously not conducive to the instantaneous effect of the switch mechanism.
[0078] In view of the above technical problems, the embodiment of the utility model makes it possible for the driving body 21 to separate from the first side of the swing arm 32 and the elastic member 4 to abut against the second side of the swing arm 32 when the driving block 2 is in the first position. When the driving block 2 is in the second position, the driving body 21 abuts against the first side of the swing arm 32 and the elastic member 4 separates from the second side of the swing arm 32.
[0079] Combination Fig. 9 It can be seen that the advantage of the above scheme of the embodiment of the utility model is that when the swing arm 32 needs to be driven forward to switch the switch mechanism to the closed state, the plug pin is inserted. Since the driving block 2 is in the first position, the driving body 21 is separated from the first side of the swing arm 32, so that there is an avoidance distance between the driving body 21 and the swing arm 32. When the driving block 2 is driven by the plug pin to move, the driving body 21 will press the elastic member 4, so that the elastic member 4 moves from the position against the second side of the swing arm 32 to the position separated from the second side of the swing arm 32. At this time, the elastic member 4 no longer acts on the second side of the swing arm 32, until the movement distance of the driving body 21 is equal to the avoidance distance, the driving body 21 is against the first side of the swing arm 32 and the elastic member 4 is separated from the second side of the swing arm 32. In this way, the moving driving body 21 drives the swing arm 32 forward to switch the switch mechanism to the closed state, and the swing arm 32 will not be subjected to the reverse force from the elastic member 4, which significantly improves the forward movement speed of the swing arm 32. At the same time, the driving block 2 moves to the second position.
[0080] On the contrary, if attached Fig.10 As shown, when the swing arm 32 needs to be driven in the reverse direction so that the switch mechanism switches to the disconnected state, the plug pin is pulled out. Since the drive block 2 is in the second position, the elastic member 4 is separated from the second side of the swing arm 32, so that there is also an avoidance distance between the elastic member 4 and the swing arm 32. Then, after the plug pin is pulled out a certain distance, the elastic member 4 in the reset motion drives the drive block 2, so that it moves from the position where the drive body 21 and the first side of the swing arm 32 are against each other to the position where it is separated from the first side of the swing arm 32. At this time, the drive body 21 no longer acts on the first side of the swing arm 32, until the movement distance of the elastic member 4 is equal to the avoidance distance, the elastic member 4 is against the second side of the swing arm 32 and the drive body 21 is separated from the first side of the swing arm 32. In this way, the moving elastic member 4 drives the swing arm 32 in the reverse direction so that the switch mechanism switches to the disconnected state, and the swing arm 32 will not be subjected to the positive force from the drive block 2, which significantly increases the reverse movement speed of the swing arm 32. At the same time, the drive block 2 resets to the first position.
[0081] By improving the assembly method among the driving block 2, the swing arm 32 and the elastic member 4, when the swing arm 32 of the swing block 3 is driven forward by the driving block 2, the elastic member 4 will not exert a reverse force on the swing arm 32, and when the swing arm 32 of the swing block 3 is driven reversely by the elastic member 4, the driving block 2 will not exert a positive force on the swing arm 32, thereby significantly improving the movement speed of the swing arm 32 and achieving a better instantaneous on-off effect of the switch mechanism, which is conducive to curbing or even avoiding arcing when the moving contact piece 5 and the static contact piece 6 in the switch mechanism are in contact or separated.
[0082] The assembly method between the driving block 2 and the swing block 3 can be seen in Figure 3 , Figure 7 and Figure 8 , further combined with Fig.11 It can be seen that the swing arm 32 has a through hole 321, and the connecting arm 22 passes through the through hole 321. For example, the end of the swing arm 32 away from the swing body 31 has a through hole 321, and the through hole 321 can be a bar hole, for example, and the connecting arm 22 of the driving block 2 can movably pass through the through hole 321.
[0083] As attached Figure 3-Figure 6 As shown, the end of the driving body 21 connected to the connecting arm 22 has a transmission surface 212, and the transmission surface 212 is used to drive the first side of the swing arm 32; when the driving block 2 is in the first position, there is a gap between the transmission surface 212 and the first side of the swing arm 32 to serve as an air avoidance stroke H (see Figure 8 ).
[0084] A portion of the end surface of the driving body 21 facing the swing arm 32 is connected to the connecting arm 22, and the remaining portion of the end surface serves as a transmission surface 212 for contacting the first side of the swing arm 32 to drive the swing arm 32. For example, Figure 6 The middle area where the connecting arm 22 is connected to the end surface of the driving body 21 facing the swing arm 32 is exemplified, and the area of the end surface of the driving body 21 facing the swing arm 32 surrounded by the outside of the connecting arm 22 serves as the transmission surface 212 .
[0085] As attached Figure 8 As shown, when the driving block 2 is in the first position, there is a gap between the transmission surface 212 and the first side of the swing arm 32 as an air avoidance stroke H, so that when the swing arm 32 of the swing block 3 is driven forward by the driving block 2, the elastic member 4 will not exert a reverse force on the swing arm 32, and when the swing arm 32 of the swing block 3 is driven reversely by the elastic member 4, the driving block 2 will not exert a positive force on the swing arm 32.
[0086] In the embodiment of the utility model, the air avoidance stroke H is greater than or equal to the swing stroke of the swing arm 32, that is, the compression stroke of the elastic member 4 (i.e. the avoidance distance mentioned above) is greater than or equal to the swing stroke of the swing arm 32, so as to ensure that the air avoidance is in place and that the swing arm 32 is not subject to any force that hinders its swinging during its swinging process, so that the swing arm 32 can swing into place smoothly, reliably and quickly.
[0087] In some examples, such as the attached Figure 8 and attached Figure 6 As shown, when the driving block 2 is in the first position, the transmission surface 212 is parallel to the first side surface of the swing arm 32 .
[0088] When the driving block 2 is in the first position, the transmission surface 212 of the driving body 21 is parallel to the first side surface of the swing arm 32. On the one hand, this is conducive to the driving body 21 and the swing arm 32 being driven in a face-to-face manner at the moment of initial contact, so that the driving force on the swing arm 32 is more concentrated and stable. On the other hand, when the driving block 2 moves to a clearance distance between it and the swing arm 32 under the driving action of the elastic member 4, the transmission surface 212 of the driving body 21 is also parallel to the first side surface of the swing arm 32, effectively avoiding the interference of the driving body 21 with the swing arm 32 in the retreat movement, which is conducive to improving the movement speed of the swing arm 32, optimizing the instantaneous effect and reducing the retreat stroke of the swing arm 32.
[0089] In the embodiment of the utility model, the driving block 2 applies a compressive force to the elastic member 4. In particular, the direction of the compressive force applied by the driving block 2 to the elastic member 4 is consistent with the expansion and contraction direction of the elastic member 4. Figure 3 -Attached Figure 8 As shown, the driving point of the driving component 001, such as the plug pin, on the driving body 21, the driving point of the connecting arm 22 on the elastic member 4, and the supporting point of the shell 1 on the elastic member 4 are on the same straight line. Therefore, the driving force on the elastic member 4 is positive pressure, which is more beneficial for reducing the precision requirements of the elastic member 4, improving the fault tolerance of the elastic member 4, improving the structural stability of the elastic member 4, and improving the stability (i.e. balance) of the driving process.
[0090] In some current technical solutions, the driving force applied to the elastic member 4 is lateral pressure, so that the elastic member 4 is bent as a whole (i.e., the axis of the elastic member 4 is changed from a straight line to a curve) to achieve instantaneous action and reset effects. However, the method of using lateral pressure to provide force requires extremely high process and precision of the elastic member 4 (for example, the two ends of the compression spring must be ground flat to maintain a high degree of parallelism), which not only makes the elastic member 4 prone to movement failure, but also causes its structural stability to be low. The embodiment of the utility model can obviously solve the technical problems existing in the current technical solutions by applying positive pressure to the elastic member 4.
[0091] Based on the better fault tolerance of the elastic member 4 in the embodiment of the utility model, the elastic member 4 can be allowed to adopt a variety of structural forms. In some examples, the elastic member 4 involved in the embodiment of the utility model includes: a compression spring, a retaining spring or a plastic elastomer. When the elastic member 4 is a retaining spring, the retaining spring can be designed to include a spring body and spring arms symmetrically arranged on both sides of the spring body. The spring body can be assembled to the housing 1, one of the spring arms is connected to the connecting arm 22 of the driving block 2, and the other spring arm is connected to the housing 1, so that the direction of the compressive force applied by the driving block 2 to the elastic member 4 is consistent with the expansion and contraction direction of the elastic member 4.
[0092] In some examples, such as the attached Figure 3 As shown, the elastic member 4 is a compression spring, which has the advantages of simple structure, convenient assembly, excellent instantaneous effect, etc.
[0093] The driving body 21 is driven by the driving component 001, as shown in the attached Figure 7 As shown, the driving body 21 has a driving surface 211, which is arranged obliquely relative to the driving direction of the driving component 001. The driving surface 211 is used to receive the driving component 001, so that when the driving component 001 moves along the first direction, the driving block 2 is driven to move along the second direction; wherein the first direction intersects with the second direction, for example, the first direction and the second direction can be perpendicular to each other, one of them is along the vertical direction, and the other is along the horizontal direction.
[0094] Exemplarily, the driving surface 211 is disposed at the end of the driving body 21 on the side away from the connecting arm 22. If the driving direction of the driving component 001 is in the vertical direction, the driving surface 211 can be arranged tilted relative to the vertical direction, so that the driving block 2 moves in the horizontal direction under the drive of the driving component 001.
[0095] It can be seen that by providing an inclined driving surface 211 on the driving body 21 , the driving force direction of the driving component 001 can be changed and applied to the driving block 2 , so that the driving block 2 moves smoothly along the target direction.
[0096] Further, for any of the switch mechanisms mentioned above, the housing 1 and the driving body 21 have matching guide structures, and the guide structures are configured to guide the driving block 2 to move in the second direction. Further, the guide structures are also configured to prevent the driving block 2 from moving in the first direction. By providing the guide structures, the smoothness and stability of the movement of the driving block 2 are more favorable, and the driving block 2 can also be supported.
[0097] For example, if Fig.12 and attached Fig.13As shown, the guide structure includes a rib 213 and a guide groove 11 for accommodating the rib 213. The rib 213 can be loosely matched with the guide groove 11 so that one of the guide groove 11 and the rib 213 can guide the movement of the other along the second direction.
[0098] Furthermore, the clearance fit between the guide groove 11 and the rib 213 can also enable the driving block 2 to perform transitional motion along other directions intersecting the second direction, for example, the transitional motion can be a slight rotation. The transitional motion of the driving block 2 can occur after the driving block 2 moves to abut against the swing arm 32 to improve the positioning effect of the swing block 3. The embodiment of the utility model does not specifically limit the structural form of the rib 213 and the guide groove 11. For example, both can be strip-shaped or other shapes, as long as they can meet the above requirements.
[0099] One of the rib 213 and the guide groove 11 is provided on the driving body 21, and the other is provided on the housing 1, for example, Figure 5 and Fig.13 The example shows that the ribs 213 are arranged on the driving body 21, and the guide grooves 11 are arranged on the shell 1. In addition, two groups of ribs 213 are symmetrically arranged on both sides of the driving body 21. Correspondingly, one group of guide grooves 11 is respectively arranged on the shell 1 on both sides of the driving body 21.
[0100] As attached Figure 5 As shown, another strip rib 214 can be provided on the bottom wall of the convex rib 213, and the strip rib 214 is used to contact the bottom wall of the guide groove 11 to reduce the contact area and make the driving block 2 move smoothly. Furthermore, the surface of the strip rib 214 that contacts the guide groove 11 is an arc surface to further promote the smooth movement of the driving block 2.
[0101] In combination with the various arrangements of the driving block 2 , the swing block 3 , and the elastic member 4 mentioned above, the structures of the driving block 2 and the swing block 3 and their arrangements in the housing 1 are further described below.
[0102] For the drive block 2, in some examples, as shown in the attached Figure 6 As shown, along the moving direction of the driving block 2 , the driving surface 211 of the driving body 21 , the transmission surface 212 of the driving body 21 , and the connecting arm 22 are distributed in sequence.
[0103] Combination Figure 3-Figure 8, the axial direction of the connecting arm 22 is consistent with the movement direction of the driving block 2, one end of the connecting arm 22 is connected to the driving body 21, and the other end of the connecting arm 22 is connected to the elastic member 4, wherein the connection between the connecting arm 22 and the elastic member 4 may be non-detachable, or may be and is expected to be detachable. Taking the detachable connection as an example, a connecting column may be provided at the end of the connecting arm 22 and an annular step may be formed between the two, and the end of the elastic member 4 in the form of a compression spring may be sleeved on the connecting column and the end may abut against the annular step at the end of the connecting arm 22.
[0104] In some examples, combined Figure 6 It can be seen that along the insertion direction of the driving component 001, such as the plug pin, the driving body 21 includes a connecting portion and an extending portion distributed in sequence, wherein the connecting portion of the driving body 21 is connected to the connecting arm 22, and the driving surface 211 is formed on the corresponding end surface of the connecting portion of the driving body 21. Exemplarily, the convex rib 213 mentioned above can be located on the extending portion of the driving body 21.
[0105] As attached Figure 6 As shown, along the moving direction of the driving component 001, the size of the driving body 21 is larger than the size of the connecting arm 22. On the one hand, when the driving block 2 moves to the second position, the driving body 21 can provide a larger area to abut against the driving component 001, so that the driving block 2, that is, the switch mechanism, can be reliably stopped based on the driving component 001. On the other hand, when the driving block 2 moves to the second position, the driving body 21 can also provide a larger area to abut against the swing arm 32, so that the swing arm 32, that is, the swing block 3, can be reliably stopped based on the driving block 2.
[0106] For the swing block 3, in some examples, such as the attached Figure 3-Figure 8 , and attached Fig.11 As shown, the first end of the swing body 31 is rotatably connected to the shell 1, the second end of the swing body 31 opposite to the first end is connected to the moving contact piece 5, one end of the swing arm 32 is connected to the swing body 31, and the other end of the swing arm 32 extends in a direction away from the swing body 31 and is movably connected to the connecting arm 22.
[0107] Combined with the arrangement of the driving block 2 and the swing block 3 in the housing 1 mentioned in the present invention, and the swing arm 32 extends in a direction away from the swing body 31 and its distal end is movably connected to the connecting arm 22, it can be seen that the driving component 001, such as the distance between the driving point of the plug pin to the driving body 21 and the hinge point of the swing body 31 and the housing 1, is the driving force arm of the switch mechanism mentioned above. Obviously, the driving force arm of the switch mechanism in the embodiment of the present invention is longer than that of the prior art. It can be seen that the switch mechanism provided in the embodiment of the present invention also has the advantages of a longer driving force arm and a smaller required driving force, which is conducive to improving the user's operating experience.
[0108] One end of the swing arm 32 is connected to the swing body 31, and the other end of the swing arm 32 extends along a side close to the shell 1 having a socket (for driving a component 001, such as the insertion of a plug pin). By making the connection position between the swing arm 32 and the swing body 31 closer to the first end of the swing body 31, there is a relatively large space between the swing arm 32 and the second end of the swing body 31 to accommodate the relatively large elastic member 4, and there is a relatively small space between the swing arm 32 and the first end of the swing body 31 to accommodate the relatively small driving block 2, which is conducive to the compact assembly of the driving block 2, the swing block 3 and the elastic member 4, and is conducive to reducing the volume of the switching mechanism.
[0109] Combination Figure 3 As shown in the orientation, the swing body 31 is located below the housing 1 and is arranged obliquely, the swing arm 32 is located above the swing body 31, the elastic member 4 is located in the second side region of the swing arm 32, which is the region formed by the swing arm 32 and the right side portion of the swing body 31, and the drive block 2 is located in the first side region of the swing arm 32. It can be seen that the switch mechanism provided by the embodiment of the utility model has its components assembled compactly to reduce the space occupied, which is conducive to the miniaturization of the switch mechanism and improves the versatility of the switch mechanism.
[0110] As described above, the driving block 2 is driven by the driving component 001. In some examples, such as the attached Fig.11 As shown, the swing arm 32 is arranged obliquely relative to the driving direction of the driving component 001. For example, the angle between the swing arm 32 and the driving direction of the driving component 001 can be 10°-45°, etc. By arranging the swing arm 32 obliquely relative to the driving direction of the driving component 001, it is beneficial to reduce the occupied space of the swing arm 32, thereby facilitating the miniaturization of the switch mechanism.
[0111] Based on the above, and see the attached Fig.11The swing arm 32 and the swing body 31 are arranged at an angle, and the swing arm 32 is inclined toward the direction of the second end close to the swing body 31. For example, the angle between the swing arm 32 and the swing body 31 is less than 90° and can be greater than or equal to 30°, etc., which not only reduces the space occupied by the swing arm 32, but also helps to optimize the driving efficiency between the driving block 2 and the swing block 3.
[0112] Furthermore, in order to enhance the stability of the swing arm 32, the embodiment of the utility model may provide a reinforcing rib 34 between the swing arm 32 and the swing body 31. For example, the reinforcing rib 34 is formed on the surface of the swing body 31, and one end of the reinforcing rib 34 is connected to the end of the swing arm 32 connected to the swing body 31, and the other end of the reinforcing rib 34 extends to the second end of the swing body 31.
[0113] In the embodiment of the utility model, the first end of the swing body 31 can be hinged to the end of the housing 1 away from the insertion hole, for example, as shown in the attached Fig.11 As shown, two opposite sides of the first end of the swing body 31 are provided with rotating shafts 33 , and corresponding positions on the housing 1 are provided with shaft holes.
[0114] On this basis, the swing body 31 can be arranged tilted so that there is a gap between the second end of the swing body 31 and the end of the shell 1 away from the insertion hole, which prevents the swing body from interfering with the shell 1 when swinging.
[0115] In combination with any of the above-mentioned switch mechanisms, in some examples, the switch mechanism provided by the embodiments of the utility model also includes a stroke amplification structure (not shown in the figure), which abuts or is connected to the drive block 2. The stroke amplification structure can drive the drive block 2 under the drive of the drive component 001 to amplify the movement stroke of the drive block 2.
[0116] The above-mentioned stroke amplification structure can adopt currently known structural parts, such as a lever structure, etc. By arranging the stroke amplification structure at the front end of the driving block 2, the driving component 001, such as a plug pin, directly drives the stroke amplification structure when driving, and then the stroke amplification structure transmits the driving force to the driving block 2, which can achieve the purpose of amplifying the movement stroke of the driving block 2, and can also be understood as reducing the driving stroke of the driving component 001. For example, when the movement stroke of the driving block 2 is determined, the switch mechanism provided with the stroke amplification structure will have a smaller driving stroke of the driving component 001 and a higher driving sensitivity than the switch mechanism without the stroke amplification structure.
[0117] For any of the switch mechanisms mentioned above, Figure 1 and attached Figure 2As shown, the housing 1 can be configured to include two such arrangements, and the two housings 1 are connected to form a receiving space to accommodate the other components in the switch mechanism. One of the two housings 1 provides a connection point to connect with the elastic member 4, so as to support the elastic member 4. For example, the connection point can be a boss 12.
[0118] For the through hole (which is a through hole) formed on the housing 1 and used for the driving component 001 to enter and exit, a portion of the through hole is formed in one of the housings 1, and the other portion of the through hole is formed in the other housing 1. In addition, a stop structure can also be provided on the inner wall of the housing 1 to support and limit the swing block 3 in the disconnected state of the switch mechanism, so that its position is stable.
[0119] On the other hand, the embodiment of the utility model further provides a socket, which comprises: a socket housing, a socket assembly disposed inside the socket housing, and a switch mechanism, wherein the switch mechanism adopts any of the switch mechanisms involved in the embodiment of the utility model. The switch mechanism is located between the socket assembly and the power circuit, and the drive block 2 of the switch mechanism can be driven by the plug pin to control the on and off of the socket assembly and the power circuit.
[0120] The socket provided by the embodiment of the utility model has all the advantages of the switch mechanism provided by the embodiment of the utility model.
[0121] The switch mechanism is located between the socket assembly and the power circuit. In some examples, the switch mechanism is configured to be pressed by the ground pole pin to control the connection between the socket assembly and the power circuit, wherein the socket assembly can include either a positive pole socket or an L pole socket.
[0122] In some examples, the socket is an AC socket, and correspondingly, the socket assembly includes an L-pole socket and an N-pole socket, and may also include a ground-pole socket.
[0123] In some other examples, the socket is a DC socket, and correspondingly, the socket assembly may include a positive socket and a negative socket, and may also include a ground socket.
[0124] In some embodiments, taking a DC socket as an example, when a plug is inserted into the socket, the ground plug is longer and is inserted before the positive and negative plugs, so that the ground plug can be used as a driving component 001 to drive the driving block 2 in the switch mechanism.
[0125] In the embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The term "plurality" refers to two or more, unless otherwise clearly defined.
[0126] The above description is only for the purpose of facilitating the technical solution of the present invention to be understood by those skilled in the art, and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
