The following embodiments are only used to illustrate the technical solution of the present application more clearly, and thus are only examples and should not be used to limit the protection scope of the present application.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used herein are for the purpose of describing specific embodiments only and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0045] In the description of the embodiments of this application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order, or primary-secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "a plurality" is more than two, unless otherwise specifically defined.

[0046] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0047] In the description of the embodiments of this application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: the existence of A, the simultaneous existence of A and B, and the existence of B. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0048] In the description of the embodiments of this application, the term "a plurality" means more than two (including two). Similarly, "multiple groups" means more than two groups (including two groups), and "multiple pieces" means more than two pieces (including two pieces).

[0049] In the description of the embodiments of this application, the orientation or positional relationship indicated by technical terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the embodiments of this application and simplifying the description, and does not indicate or imply that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of this application.

[0050] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installation", "connection", "connection", "fixation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can also be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0051] For the convenience of later maintenance operations, the chassis of the industrial control computer can be assembled by a box body and a box cover. The box cover is rotatably connected to the box body through a vertical shaft. In the working state, the box cover needs to be locked to the box body by screws. When maintenance is required, the screws are removed, and the box cover is manually flipped open to perform maintenance operations such as inspection and maintenance on the circuit components inside the box body. Although such a method can simplify the maintenance operation of the industrial control computer to a certain extent, it still requires holding the box cover to flip it open and keep it from falling, so it cannot effectively bring convenience to maintenance.

[0052] Based on this, the present application proposes a flipping mechanism, which is connected between the box body and the box cover, and can drive the box cover to automatically flip open and stay in the open state when the box cover and the box body are unlocked, so that the operation and maintenance personnel can better perform inspection and maintenance on the corresponding circuit components in the chassis.

[0053] It can be understood that the flipping mechanism proposed in the present application can not only be applied to industrial control computers or other computers to realize the automatic flipping open of the box cover, but also be applied to other mechanical fields to realize the automatic flipping between two components.

[0054] According to one aspect of the embodiments of the present application, an industrial control computer is provided. For details, please refer to Figures 1 to 3 , Figure 1 shows the structure of the industrial control computer when the box cover is in the closed state, Figure 2 shows the structure of the industrial control computer when the box cover is in a partially open state, Figure 3 shows the structure of the industrial control computer when the box cover is in the fully open state. As shown in the figure, the industrial control computer 500 includes a flipping mechanism 100, a box body 200, and a box cover 300. The box cover 300 is rotatably connected to the box body 200. The flipping mechanism 100 is respectively connected to the box body 200 and the box cover 300. The flipping mechanism 100 is used to drive the box cover 300 to automatically flip open relative to the box body 200 and stay in the open state.

[0055] Further, as Figure 2 and Figure 3As shown in the figure, the box body 200 has a rear panel 210. A power module 310 is fixed to the inner wall of the box cover 300. The flipping mechanism 100 is respectively connected to the inner wall of the rear panel 210 and one side of the power module 310. The flipping mechanism 100 can drive the box cover 300 and the power module 310 to flip automatically relative to the box body 200 together.

[0056] According to another aspect of the embodiments of the present application, a flipping mechanism is provided. The flipping mechanism includes, but is not limited to, an industrial computer applied in the above embodiments. For details, please refer to Figures 4 to 7 , wherein, Figure 4 and Figure 5 respectively show the overall structure of the flipping mechanism from two perspectives, Figure 6 shows the exploded structure of the flipping mechanism, Figure 7 shows in Figure 4 the internal structure of the flipping mechanism shown in. As shown in the figure, the flipping mechanism 100 includes: a base body 110, a sliding bar 120, a pushing member 130, a first transmission wheel 140, a second transmission wheel 150, and a transmission shaft 160.

[0057] The base body 110 can be Figure 4 a shell-like structure that covers other components as shown in the figure. Of course, it can also be a block-like or other shaped structure. The base body 110 is used to be fixedly connected to the first component. In the Figure 2 and Figure 3 shown industrial computer 500 to which the flipping mechanism 100 is applied, the base body 110 is fixedly connected to the box body 200. For example, it can be fixed to the inner wall of the rear panel 210. Specifically, the base body 110 and the box body 200 can be assembled and fixed by means such as screw connection and snap connection.

[0058] The sliding bar 120 is slidably connected to the base body 110. Specifically, as Figure 6 and Figure 7 shown in the figure, a slide rail 111 can be provided in the base body 110, and the sliding bar 120 is in sliding fit with the slide rail 111, and the slide rail 111 plays a role of guiding the sliding of the sliding bar 120. Of course, there can also be other sliding fit methods between the sliding bar 120 and the base body 110, such as a sliding hole is opened on the base body 110, and the sliding bar 120 is slidably inserted into the sliding hole and other methods.

[0059] Both ends of the pushing member 130 are respectively hinged to the base body 110 and the sliding bar 120. Specifically, as Figure 6 shown in the figure, the first end 131 of the pushing member 130 is connected to the base body 110, and the second end 132 is connected to the sliding bar 120. The pushing member 130 can adopt the illustrated gas strut hydraulic rod. When not restricted by external forces, the piston rod of the gas strut hydraulic rod will automatically extend and drive the sliding bar 120 to move relative to the base body 110 along Figure 6The push member 130 slides in the direction indicated by the middle arrow. Since the gas-supported hydraulic rod is a non-violent energy storage power source, it will smoothly and slowly push the sliding bar 120 to slide relative to the base 110, and will not cause violent impacts between the components, thereby effectively ensuring the stability of the overall structure of the flip mechanism 100. Of course, in other embodiments, the push member 130 can also be a gas pressure rod, an elastic member, or other types of hydraulic rods. For some elastic members with large instantaneous thrust release, shock-absorbing pads or other buffering and shock-absorbing structures can be set to reduce the impact and vibration generated to ensure the stability of the flip mechanism 100.

[0060] The first transmission wheel 140 is in transmission cooperation with the sliding bar 120 through the second transmission wheel 150. Figure 6 When the first transmission wheel 140 is driven to rotate by the second transmission wheel 150, the rotation directions of the second transmission wheel 150 and the first transmission wheel 140 are as shown in FIG. Figure 6 In the illustrated embodiment, the first transmission wheel 140 and the second transmission wheel 150 are both gears, the sliding bar 120 is a rack, and the second transmission wheel 150 is meshed with the first transmission wheel 140 and the sliding bar 120. In other embodiments, the first transmission wheel 140 and the second transmission wheel 150 can both be sprockets, and correspondingly, the sliding bar 120 is a chain, and the second transmission wheel 150 can have two sets of coaxial sprockets, one set of sprockets meshes with the sliding bar 120 for transmission, and the other set of sprockets is transmitted to the first transmission wheel 140 through another chain.

[0061] The transmission shaft 160 is connected to the first transmission wheel 140, and the transmission shaft 160 is also used to be fixedly connected to the second component. Figure 2 and Figure 3 In the industrial computer 500 using the flip mechanism 100, the transmission shaft 160 is fixedly connected to the box cover 300, and can be fixed on one side of the power module 310 on the inner wall of the box cover 300. When the transmission shaft 160 rotates with the first transmission wheel 140, the second component is driven to flip relative to the first component.

[0062] In summary, taking the flip mechanism 100 applied to the industrial computer 500 and realizing the automatic flipping and opening of the box cover 300 as an example, when the box cover 300 is in the closed state, the push member 130 is in the power storage state. When the box cover 300 is no longer locked on the box body 200, the push member 130 will not be restricted by external force. At this time, the push member 130 will drive the sliding bar 120 to move along the Figure 6 The second transmission wheel 150 and the first transmission wheel 140 slide in the direction indicated by the straight arrow. Figure 6The first transmission wheel 140 rotates in the direction indicated by the rotation arrow on its outer periphery, and the transmission shaft 160 is driven to rotate. Accordingly, the box cover 300 fixed relatively to the transmission shaft 160 is flipped open with the transmission shaft 160 as the axis, thereby realizing the automatic opening of the box cover 300, and after opening, the box cover 300 can be kept in the open state with the help of the pusher 130.

[0063] When the box cover 300 needs to be closed, the box cover 300 can be pressed to transmit power in reverse from the transmission shaft 160 to the sliding bar 120 to overcome the force of the pusher 130 to close the box cover 300. After closing, the box cover 300 can be locked to keep it in the closed state.

[0064] It should be noted that the second transmission wheel 150 is connected between the sliding bar 120 and the first transmission wheel 140 to be responsible for the power transmission between the two, mainly to reduce the flipping speed of the second component (for example, the box cover 300) relative to the first component (for example, the box body 200) as much as possible with the help of the pushing member 130 to avoid generating large impact and vibration. Based on this, in order to achieve the purpose of deceleration, the diameter of the second transmission wheel 150 is smaller than the diameter of the first transmission wheel 140.

[0065] In some other embodiments, the second transmission wheel 150 may be removed, that is, the sliding bar 120 and the first transmission wheel 140 are directly meshed and transmitted, and the relative position of the sliding bar 120 and the first transmission wheel 140 is adjusted so that the rotation direction of the first transmission wheel 140 meets the direction required for the flipping of the second component, so as to Figure 6 For example, when the second transmission wheel 150 is removed, the sliding bar 120 needs to be meshed under the first transmission wheel 140, so that when the sliding bar 120 slides in the direction indicated by the straight arrow in the figure, it can still drive the first transmission wheel 140 to rotate in the direction indicated by the rotation arrow on its periphery. This arrangement can reduce the number of parts and reduce production costs. If the second component flips faster than the first component, other shock-absorbing methods can be used to reduce impact and vibration, such as setting a shock-absorbing pad and filling grease.

[0066] In summary, in the flipping mechanism 100 provided by the embodiment of the present application, the base body 110 is fixedly connected to the first component, the transmission shaft 160 is fixedly connected to the second component, a sliding bar 120 is slidably arranged on the base body 110, a pushing member 130 is connected between the base body 110 and the sliding bar 120, and the sliding bar 120 is drivingly connected to the transmission shaft 160 through at least one transmission wheel (the first transmission wheel 140, or the combination of the first transmission wheel 140 and the second transmission wheel 150). After being arranged in this way, the sliding bar 120 can automatically slide with the assistance of the pushing member 130 and drive the second component to flip relative to the first component through the transmission wheel and the transmission shaft 160. For the industrial personal computer 500 applying the flipping mechanism 100, the cover 300 can be automatically flipped open and kept in the open state, so that the maintenance personnel can conveniently perform disassembly and maintenance operations in the box body 200, improving the maintenance efficiency.

[0067] For the convenience of description and understanding, hereinafter, for the first component and the second component, the box body 200 and the cover 300 on the industrial personal computer 500 are taken as examples for illustration, but this does not limit the specific implementation manners of the first component and the second component.

[0068] Considering that when the cover 300 is locked to the box body 200 and the industrial personal computer 500 is working properly, the power stored on the pushing member 130 tends to be transmitted to the cover 300 through the sliding bar 120, the second transmission wheel 150, the first transmission wheel 140 and the transmission shaft 160, which will cause a large force to always exist between the cover 300 and the box body 200, thus inevitably affecting the overall stability and service life of the industrial personal computer 500.

[0069] In view of the above problems, in order to avoid stress between the cover 300 and the box body 200 when the industrial personal computer 500 is in the working state, the present application further designs the connection between the transmission shaft 160 and the first transmission wheel 140 to be unlockable. Specifically, the transmission shaft 160 is connected to the first transmission wheel 140 in a movable manner, and when the transmission shaft 160 moves relative to the first transmission wheel 140, it can be relatively locked or unlocked with the first transmission wheel 140.

[0070] When the first transmission wheel 140 and the transmission shaft 160 are relatively unlocked, the two cannot rotate coaxially, that is, in this state, the power stored on the pushing member 130 will not be finally transmitted to the cover 300, so no stress will be generated between the cover 300 and the box body 200.

[0071] When the first transmission wheel 140 and the transmission shaft 160 are relatively locked, the two can rotate coaxially. In this state, when the locking between the cover 300 and the box body 200 is released, the pushing member 130 can normally drive the cover 300 to automatically flip open.

[0072] Specifically, when the transmission shaft 160 moves relative to the first transmission wheel 140, the transmission shaft 160 can be circumferentially fixed or unfixed relative to the first transmission wheel 140, thereby realizing relative locking or unlocking between the two.

[0073] For the unlockable manner between the transmission shaft 160 and the first transmission wheel 140, a specific embodiment is provided below. Please refer to Figures 8 to 10 where Figure 8 shows the end face structure of the first transmission wheel 140, Figure 9 shows the three-dimensional structure of the transmission shaft 160, Figure 10 shows the three-dimensional structure of the transmission shaft 160 and the first transmission wheel 140 in a mating state.

[0074] As Figure 8 shown, a first sliding hole 141 is formed in the first transmission wheel 140. The first sliding hole 141 has a first position 1411 and a second position 1412. The first position 1411 is at the axis of the first transmission wheel 140, and the second position 1412 deviates from the axis of the first transmission wheel 140. A first engaging portion 171 is provided on one side of the first position 1411 facing away from the second position 1412. As Figure 9 shown, a second engaging portion 172 is provided on the transmission shaft 160. The first engaging portion 171 and the second engaging portion 172 can be a convex and a groove that can be mutually engaged and separated, or can also be two blocks that can be mutually engaged and separated, etc.

[0075] When the transmission shaft 160 is inserted into the second position 1412, the second engaging portion 172 is separated from the first engaging portion 171. At this time, the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked and cannot rotate coaxially. Specifically, as Figure 8 and Figure 10 shown, the second position 1412 can be located on one side of the first position 1411 facing away from the outer circumferential engagement of the first transmission wheel 140 ( Figure 10 at M in

[0076] ). Since the second position 1412 deviates from the axis of the first transmission wheel 140, when the transmission shaft 160 is inserted into the second position 1412, the teeth on the first transmission wheel 140 (the teeth meshing with the second transmission wheel 150 or the teeth meshing with the sliding bar 120) and the transmission shaft 160 cooperate with each other to form a rotational restriction on the first transmission wheel 140. Therefore, the power transmitted by the pushing member 130 to the first transmission wheel 140 through the sliding bar 120 and the second transmission wheel 150 will not cause the first transmission wheel 140 to rotate. Figure 10In the specific embodiment shown, a guiding column 112 is fixedly arranged on the base body 110, a guiding hole 142 is formed on the first transmission wheel 140, and the guiding column 112 is in sliding fit with the guiding hole 142, so as to realize the rotation guiding and limiting of the first transmission wheel 140, so that the first transmission wheel 140 can only rotate relative to the base body 110 and will not shift in position. In addition, as Figure 8 shown, the included angle α between the connecting lines (two dotted lines in the figure) of both ends of the guiding hole 142 and the axis of the first transmission wheel 140 can be set to 90°, so as to limit the flipping angle of the box cover 300 relative to the box body 200 to 90° by abutting the guiding column 112 against both ends of the guiding hole 142.

[0077] When the transmission shaft 160 moves from the second position 1412 to the first position 1411 along the first sliding hole 141, it is in the Figure 10 shown state. In this state, the second engaging portion 172 is engaged with the first engaging portion 171. At this time, the transmission shaft 160 and the first transmission wheel 140 are relatively locked, and the two are relatively fixed and can rotate coaxially.

[0078] In order to ensure that when the transmission shaft 160 and the first transmission wheel 140 are relatively locked, the transmission shaft 160 can be stably maintained at the first position 1411, the present application further improves the specific shapes of the transmission shaft 160 and the first sliding hole 141. For details, please refer to Figures 8 to 10 . As Figure 8 shown, the width d1 of the first position 1411 is greater than the width d2 of the second position 1412, and the width d3 of the remaining positions in the first sliding hole 141 is the same as the width d2 of the second position 1412.

[0079] Please refer to Figure 9 and Figure 10 , and further in combination with Figure 11 , the transmission shaft 160 includes a shaft body 161, a connecting disc 162 and a first elastic member 163. One side of the connecting disc 162 is used for fixedly connecting with the power supply module 310. The shaft body 161 is fixedly connected with the connecting disc 162 along the circumferential direction and is movably connected with the connecting disc 162 along the axial direction. In Figure 9 and Figure 11 shown specific embodiments, a sliding cavity 1621 is arranged on the connecting disc 162, a sliding groove 1622 is formed on the side wall of the sliding cavity 1621, a meshing tooth 1601 is arranged on the shaft body 161, and the meshing tooth 1601 is slidably arranged in the sliding groove 1622 along the axial direction of the shaft body 161, and the meshing tooth 1601 abuts against the side wall of the sliding groove 1622 along the circumferential direction of the shaft body 161, so that the shaft body 161 and the connecting disc 162 are relatively fixed along the circumferential direction and can rotate coaxially.

[0080] As Figure 5 , Figure 10 and Figure 11As shown, after one side of the connection plate 162 is fixed to the power module 310, the first elastic member 163 will be compressed and abutted between the shaft body 161 and the power module 310 to provide an elastic force to the shaft body 161 in the direction away from the power module 310. This enables the shaft body 161 to automatically move in the direction away from the power module 310 when not restricted by other external forces.

[0081] As Figure 9 and Figure 11 shown, the shaft body 161 includes a continuous first section 1611 and a second section 1612. The first section 1611 is movably connected to the connection plate 162. The cross-sectional area of the second section 1612 is smaller than that of the first section 1611, so as to form a first step structure 1613 between the second section 1612 and the first section 1611.

[0082] The cross-sectional shape of the first section 1611 is adapted to the shape of the opening at the first position 1411, and the cross-sectional shape of the second section 1612 is adapted to the shape of the opening at the second position 1412. The second engaging portion 172 is provided on one side of the first section 1611.

[0083] When the second section 1612 is inserted into the second position 1412, the first step structure 1613 abuts against the end face of the first transmission wheel 140 to limit the axial movement of the shaft body 161 relative to the first transmission wheel 140. At this time, the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked and cannot rotate coaxially.

[0084] When the second section 1612 moves from the second position 1412 to the first position 1411 along the first sliding hole 141, the first section 1611 moves axially under the elastic force of the first elastic member 163 to be inserted into the first position 1411, and the second engaging portion 172 meshes with the first engaging portion 171, showing the Figure 10 state shown. At this time, the first transmission wheel 140 and the transmission shaft 160 are relatively locked, and the first transmission wheel 140 can drive the box cover 300 and the power module 310 to flip relative to the box body 200 through the transmission shaft 160.

[0085] Since d2 = d3 < d1, the cross-sectional area of the first section 1611 is larger than that of the second section 1612, and the cross-sectional shape of the first section 1611 is adapted to the opening shape of the first position 1411, and the cross-sectional area of the second section 1612 is adapted to the opening shape of the second position 1412. Therefore, after the first section 1611 is inserted into the first position 1411 and the second engaging portion 172 engages with the first engaging portion 171, along the extending direction of the first sliding hole 141, the first section 1611 will be limited and fixed, that is, at this time, the transmission shaft 160 cannot slide along the first sliding hole 141, ensuring that the transmission shaft 160 is reliably locked in the first position 1411, thereby ensuring the stability and reliability of the transmission between the first transmission wheel 140 and the transmission shaft 160.

[0086] Specifically for the application on the industrial control computer 500, please refer to Figure 1 and Figure 2 , the edge of the box cover 300 can be provided with inserting pieces 320, and the edge of the top of the box body 200 can be provided with limiting sockets 220. When the box cover 300 is in the closed state, the inserting pieces 320 are inserted into the limiting sockets 220, so that the box cover 300 is locked on the box body 200, and at this time, the second section 1612 is in the second position 1412, and the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked.

[0087] In the closed state, when pushing the box cover 300 along the Figure 1 direction indicated by the arrow in so that the inserting pieces 320 slide out of the limiting sockets 220, since the power module 310 and the transmission shaft 160 are relatively fixed, the box cover 300 will drive the second section 1612 to move along the first sliding hole 141 towards the first position 1411 at the same time. When the inserting pieces 320 completely slide out of the limiting sockets 220, the second section 1612 slides to the first position 1411. Under the elastic force of the first elastic member 163, the first section 1611 automatically moves axially and inserts into the first position 1411, and the second engaging portion 172 also engages with the first engaging portion 171 accordingly. At this time, without applying pressure to the box cover 300, the power stored in the pushing member 130 is sequentially transmitted to the power module 310 and the box cover 300 through the sliding bar 120, the second transmission wheel 150, the first transmission wheel 140 and the transmission shaft 160 to drive the box cover 300 to automatically flip and open.

[0088] For unlocking between the transmission shaft 160 and the first transmission wheel 140, an operating part capable of driving the shaft body 161 to move can be provided on the box body 200, or one end of the shaft body 161 can protrude from the box body 200 to form an operating part. Specifically, after pressing the box cover 300 to rotate it from the open state to the closed state, the shaft body 161 is first axially pressed through the operating part, so that the shaft body 161 overcomes the elastic force of the first elastic member 163 and moves towards the power module 310. After the first section 1611 moves out of the first position 1411, along Figure 1 the opposite direction of the arrow in it, the box cover 300 is pushed, so that the second section 1612 slides along the first sliding hole 141 from the first position 1411 to the second position 1412, the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked, and at the same time, the insertion piece 320 slides and inserts into the limit socket 220, and the box cover 300 is closed and locked to the box body 200 again.

[0089] In addition to the above-mentioned method of relatively unlocking the transmission shaft 160 and the first transmission wheel 140 by setting an operating part to drive the shaft body 161 to move, the present application also provides a more convenient solution. For details, please refer to Figure 7 , a reset component 180 can be movably arranged on the base body 110. The reset component 180 is connected to the second section 1612. The reset component 180 is used to drive the second section 1612 to move axially towards the power module 310 when moving, so that the first section 1611 moves out of the first position 1411, and the second engaging part 172 is separated from the first engaging part 171. After the first section 1611 moves out of the first position 1411, along Figure 1 the opposite direction of the arrow in it, pushing the box cover 300 can close and lock the box cover 300 to the box body 200.

[0090] Please continue to refer to Figure 7 , and further in combination with Figure 6 and Figure 12 , Figure 12 shows the structure of the reset component 180 from another perspective. As shown in the figure, the reset component 180 can include a first sliding member 181 and a second sliding member 182. The first sliding member 181 is arranged on the base body 110, and the sliding direction of the first sliding member 181 is parallel to the extending direction of the first sliding hole 141. The second sliding member 182 is slidably arranged on the first sliding member 181, and the sliding direction of the second sliding member 182 is parallel to the axial direction of the shaft body 161.

[0091] Both the first sliding member 181 and the second sliding member 182 are disposed on the side of the first transmission wheel 140 away from the connection disk 162. The second section 1612 is sequentially passed through the first sliding member 181 and the second sliding member 182. The second section 1612 is axially movable relative to the first sliding member 181 and circumferentially rotatable relative to the first sliding member 181. The second section 1612 is axially and limit-connected to the second sliding member 182 and is circumferentially rotatable relative to the second sliding member 182. A second elastic member 183 is abutted between the first sliding member 181 and the base body 110. The second elastic member 183 is used to provide an elastic force to the first sliding member 181 in the direction of its sliding towards the second position 1412.

[0092] When the cover 300 is pressed to close it and the first section 1611 is inserted into the first position 1411, by pushing the second sliding member 182, the shaft body 161 can be driven to move axially towards the power module 310. When the first section 1611 is moved out of the first position 1411, the second section 1612 enters the first position 1411, and the second elastic member 183 will automatically drive the second section 1612 to move from the first position 1411 towards the second position 1412 through the first sliding member 181, so that the second section 1612 moves to the second position 1412. Since the transmission shaft 160 is fixedly connected to the power module 310 and the cover 300, during the process that the second elastic member 183 drives the transmission shaft 160 to move towards the second position 1412, the cover 300 will be synchronously driven to move along Figure 1 the opposite direction of the arrow in the figure, so that the insertion piece 320 can be automatically inserted into the limit socket 220 for locking, thereby further eliminating the step of manually pushing the cover 300 to insert the insertion piece 320 into the limit socket 220 and improving the convenience.

[0093] For the manner in which the second section 1612 is axially movable relative to the first sliding member 181 and circumferentially rotatable relative to the first sliding member 181, it can be realized by opening a through hole in the first sliding member 181 and passing the second section 1612 through the through hole to form a clearance fit. However, considering that such a clearance fit will cause the shaft body 161 to form a cantilever structure, the second section 1612 may bend to a certain extent, which will further cause the friction force to be too large or even jam when the shaft body 161 slides in the first sliding hole 141, and cause the second engaging portion 172 and the first engaging portion 171 to be misaligned and unable to mesh normally.

[0094] In this regard, the present application further optimizes it. For details, please continue to refer to Figure 6 and Figure 8 and further in combination with Figure 13 and Figure 14 Figure 13 shows the structure of the other perspective in the state where the first transmission wheel and the transmission shaft are in cooperation. Figure 14The structure of the reset assembly is shown. As shown in the figure, a connecting sleeve 164 is provided on the second section 1612. The second section 1612 can rotate and axially move within the connecting sleeve 164. The connecting sleeve 164 can be fixedly connected to the first sliding member 181 by means of embedding or other means shown in the figure, thereby realizing the axial movement and circumferential rotation of the second section 1612 relative to the first sliding member 181. A second sliding hole 143 is also provided on the first transmission wheel 140, and the second sliding hole 143 is arranged parallel to the first sliding hole 141. A sliding portion 1641 is provided on the connecting sleeve 164, and the sliding portion 1641 is in sliding fit with the second sliding hole 143.

[0095] After the above settings, when the second elastic member 183 pushes the first sliding member 181 to slide along its sliding direction towards the second position 1412, the second sliding hole 143 provides a sliding guiding function for the sliding portion 1641, so that the connecting sleeve 164 and the first sliding member 181 can accurately slide along the extension direction of the first sliding hole 141. At the same time, the connecting sleeve 164 can provide a certain support for the second section 1612 passing through it, and drive the second section 1612 to accurately slide along the extension direction of the first sliding hole 141 when moving, that is, drive the shaft body 161 to accurately slide along the first sliding hole 141, so as to ensure that after multiple unlocking and locking operations, the second engaging portion 172 and the first engaging portion 171 can still be normally engaged.

[0096] In order to better position the connecting sleeve 164, as Figure 9 shown in the figure, a second step structure 1614 can be provided on the second section 1612. The connecting sleeve 164 is sleeved on the second section 1612 and clamped between the second step structure 1614 and the first sliding member 181 to prevent the connecting sleeve 164 from axially shifting.

[0097] In addition, in order to more conveniently operate the second sliding member 182 to drive the shaft body 161 to axially move, this application has been optimized and improved. For details, please refer to Figure 7 、 Figure 12 and Figure 13 . A limiting sleeve 165 is fixedly provided on the second section 1612, and the limiting sleeve 165 passes through the second sliding member 182. First abutting portions 1651 and second abutting portions 1652 are convexly provided at both ends of the limiting sleeve 165, and the first abutting portion 1651 is located between the second abutting portion 1652 and the first transmission wheel 140.

[0098] For the convenience of the production and assembly of the limiting sleeve 165 and the shaft body 161, as Figure 6As shown in , the second section 1612 may be provided with a thread, or the second section 1612 may be entirely provided with a screw, the limiting sleeve 165 may be provided with a conventional cylindrical hollow sleeve, the limiting sleeve 165 is sleeved on the second section 1612, and two nuts are screwed and fixed at the positions at both ends of the limiting sleeve 165 on the second section 1612, so that the limiting sleeve 165 is fixed to the second section 1612 through the two nuts, and the outer peripheries of the two nuts protrude from the limiting sleeve 165, thereby forming a first abutting portion 1651 and a second abutting portion 1652. Of course, the limiting sleeve 165, the first abutting portion 1651 and the second abutting portion 1652 may also be provided with an integral structure and fixed to the second section 1612 by welding, threaded connection, or the like.

[0099] Based on the above arrangement, the second sliding member 182 can slide within the travel between the first abutting portion 1651 and the second abutting portion 1652 relative to the limiting sleeve 165, and when the first abutting portion 1651 or the second abutting portion 1652 abuts against the second sliding member 182, the limiting sleeve 165 and the second sliding member 182 will slide synchronously, that is, the shaft body 161 will slide synchronously with the second sliding member 182. This arrangement can make it possible for the shaft body 161 to slide in the direction away from the power module 310 under the elastic force of the first elastic member 163, and at the beginning, the second sliding member 182 will not be directly driven to slide with it, but the limiting sleeve 165 will be driven to move first to make the first abutting portion 1651 abut against the second sliding member 182, and then the second sliding member 182 will be driven to slide through the first abutting portion 1651, thereby reducing the impact between the shaft body 161 and the second sliding member 182 and improving the structural stability.

[0100] See also Figure 7 and Figure 12 The reset assembly 180 further includes a button 184 that can slide relative to the base 110. The button 184 can be as follows Figure 5 As shown, the button 184 is exposed on the base 110, and when the base 110 is fixed to the inner wall of the box 200, the button 184 can be as shown. Figure 15 Specifically, the button 184 can be directly slidably connected to the base 110, or can be slidably connected to the box 200, the sliding direction of the button 184 is parallel to the axial direction of the shaft 161, and the button 184 has a force applying portion 1841, which is arranged on the side of the second sliding member 182 away from the first transmission wheel 140.

[0101] When the first section 1611 is inserted into the first position 1411, that is, the transmission shaft 160 and the first transmission wheel 140 are relatively locked, Figure 12When the button 184 is pushed in the direction indicated by the middle arrow, the button 184 will drive the second sliding member 182 to slide toward the first transmission wheel 140 through the force-applying portion 1841. When the second sliding member 182 abuts against the first abutting portion 1651, the second sliding member 182 then drives the shaft 161 to slide toward the power module 310 through the first abutting portion 1651. When the first section 1611 moves out from the first position 1411, under the elastic force of the second elastic member 183, the first sliding member 181 will drive the transmission shaft 160 to slide from the first position 1411 to the second position 1412, so that the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked.

[0102] In order to improve the operating feel of the button 184, Figure 12 As shown in the figure, a third elastic member 185 can be further arranged between the force-applying portion 1841 and the base 110. The third elastic member 185 is used to provide an elastic force to the button 184 in a direction away from the first transmission wheel 140 through the force-applying portion 1841, so that the button 184 is reset and maintained at the farthest position from the first transmission wheel 140 when not being pushed by external force, thereby providing a better feel and feedback for the next pushing operation.

[0103] In order to better ensure the structural stability of the flip mechanism 100, as Figure 14 As shown in the figure, an elastic shock-absorbing pad 190 (for example, a silicone block, foam, etc.) can be provided on the side of the first sliding member 181 away from the second elastic member 183 on the base 110. When the first sliding member 181 slides under the elastic force of the second elastic member 183, the first sliding member 181 achieves buffering by compressing the elastic shock-absorbing pad 190, thereby reducing the generation of impact and vibration to ensure the stability and reliability of the structure.

[0104] In order to better understand the operation process of the flip mechanism 100, the following is a complete description of the opening and closing process of the box cover 300 when it is applied to the industrial computer 500, taking the specific scheme shown in the figure as an example. Figure 1 As shown, when the box cover 300 is closed, the box cover 300 is pushed in the direction indicated by the arrow in the figure, and the insert 320 will slide out of the limit socket 220, and the shaft 161 will slide from the second position 1412 to the first position 1411. Then, under the elastic force of the first elastic member 163, the first section 1611 slides and inserts into the first position 1411, and the second meshing portion 172 meshes with the first meshing portion 171. Then, the stored force of the push member 130 is released, which drives the sliding bar 120 to slide relative to the base 110, and transmits the power to the power module 310 and the box cover 300 through the second transmission wheel 150, the first transmission wheel 140 and the transmission shaft 160, and the box cover 300 and the power module 310 automatically flip open to Figure 3 Status shown.

[0105] existFigure 3 In the open state shown, the box cover 300 is first pressed to make it initially closed, which will overcome the force of the push member 130 and cause the push member 130 and the slide bar 120 to retract. Figure 15 After the button 184 is toggled in the direction indicated by the dotted arrow, the force-applying portion 1841 drives the second sliding member 182 to slide toward the first transmission wheel 140. During the sliding process, when the second sliding member 182 abuts against the first abutting portion 1651, the shaft 161 slides toward the power module 310. When the first section 1611 completely slides out of the first position 1411, the stored force of the second elastic member 183 is released, which drives the first sliding member 181, the second sliding member 182, the transmission shaft 160, the power module 310 and the box cover 300 to move together. Figure 1 Slide in the opposite direction of the middle arrow, the second section 1612 slides to the second position 1412 accordingly, the transmission shaft 160 and the first transmission wheel 140 are relatively unlocked, and at the same time, the insert 320 is correspondingly inserted into the limiting socket 220, and the box cover 300 is automatically locked on the box body 200.
