[0044] like Figure 1-Figure 10 As shown, an embodiment of the present application provides a fixing device, including a shell 1, a clamping assembly 2 and a driving assembly 3.
[0045] The housing 1 has a first chamber 11 extending along a first direction X and a second chamber 12 extending along a second direction Y. The first chamber 11 is communicated with the second chamber 12 .
[0046] The clamping assembly 2 includes a clamping member 21 slidably disposed in the second chamber 12 . The clamping member 21 has an abutting portion 211 and a clamping portion 212 away from the abutting portion 211 . The clamping portion 212 can extend to the outside of the second chamber 12 for clamping the member to be fixed.
[0047] The driving assembly 3 includes a sliding member 31 slidably disposed in the first chamber 11 and a limiting member 32 that limits the sliding member 31. The sliding member 31 has a driving portion 311, which is used to connect the abutting portion 211 so that the clamping member 21 slides along the second chamber 12. The limiting member 32 is used to limit the position of the sliding member 31 in the first chamber 11.
[0048] The first direction X and the second direction Y intersect.
[0049] In the present application, the sliding member 31 is moved along the first chamber 11 so that the driving portion 311 of the sliding member 31 cooperates with the abutting portion 211 of the clamping member 21, thereby driving the clamping member 21 to slide along the second chamber 12, so that the clamping portion 212 of the clamping member 21 extends to the outside of the second chamber 12 and clamps the part to be fixed on the fixing surface, and then the sliding member 31 is limited by the limiting member 32 so that the clamping member 21 remains in a state of fixing the part to be fixed. Even in a dense and delicate box, when the operating space above the fixing plate and the part to be fixed is limited, the part to be fixed can be fixed in the second direction Y by changing the direction of the operation, that is, by operating in the first direction X, so that the components in the dense box can be effectively fixed, thereby improving practicality.
[0050] Specifically, the part to be fixed in the present application is a component, and the fixing device is used to fix the component on the fixing surface of the box. Of course, the part to be fixed can be not only a component, but also other structures or parts to be fixed that are inconvenient to operate in a small space.
[0051] In the related technology, the functions of the electric control box are increasing, while the size is getting smaller and smaller. The distance between the components in the electric control box is getting closer and closer. In the dense and delicate box, the operating space above the components is very limited. If you want to fix the components by rotating the screws with a screwdriver, the operation will be very inconvenient. Even if there are some right-angle screwdrivers that can complete the rotation of the screws in a smaller space, the angle of a single rotation is still limited, and it is still inconvenient to operate.
[0052] In the embodiment of the present application, by fixing the fixing device in the box and adjusting the position of the fixing device in the box, it is ensured that the part to be fixed can be effectively fixed, and the fixing device can be pre-set in the box according to the position of the component. When it is necessary to fix the component, the pressing member 21 can be made to slide along the second chamber 12 by operating the sliding member 31 of the fixing device, so that the pressing part 212 of the pressing member 21 extends out of the second chamber 12 and is pressed and fixed with the component. Even if the operating space above the component in the box is limited, it is still convenient to complete the fixing of the component.
[0053] In the present application, the first direction X and the second direction Y are intersecting, the second direction Y is the direction in which the fixed part needs to be fixed, that is, the normal direction of the fixing surface, and the first direction X is the operating direction. The angle between the first direction X and the second direction Y is -90° to 90°.
[0054] Specifically, a fixing device is pre-installed at a required position in the box according to the position of the component part in the box and the size of the operating space above it. The angle between the first direction X and the second direction Y in the fixing device is determined according to the fixing surface, so that the first direction X can be easily operated after the second direction Y is perpendicular to the fixing surface. A fixing device with different angles between the first direction X and the second direction Y can be selected according to the components on different fixing surfaces. Of course, for components with sufficient operating space above, traditional screw fixing can still be selected.
[0055] In some embodiments, the abutting portion 211 is a curved surface structure or a spherical structure; and / or the driving portion 311 is a curved surface structure or a spherical structure.
[0056] In the present application, the abutting portion 211 adopts an arc surface structure or a spherical structure, so that the driving portion 311 of the sliding member 31 is convenient to cooperate with the abutting portion 211, thereby driving the pressing member 21 to slide along the second chamber 12. The driving portion 311 adopts an arc surface structure or a spherical structure, which can also achieve the purpose of the driving portion 311 of the sliding member 31 conveniently cooperating with the abutting portion 211, thereby driving the pressing member 21 to slide along the second chamber 12.
[0057] In a specific embodiment, the abutting portion 211 adopts a spherical structure, and the driving portion 311 adopts a curved surface structure, and the curved surface structure abuts against the surface of the spherical structure, so that the sliding member 31 can drive the pressing member 21 to move along the second direction Y when sliding along the first direction X. The contact area between the abutting portion 211 and the driving portion 311 is small, and thus the friction force is small, which facilitates pushing the pressing member 21 to slide.
[0058] In some embodiments, the clamping assembly 2 further includes an elastic member 22 disposed in the second chamber 12 . The elastic member 22 abuts against the clamping member 21 to drive the clamping portion 212 to be retracted into the second chamber 12 .
[0059] In the present application, the driving part 311 drives the pressing member 21 to move along the second direction Y by squeezing the abutting part 211, so that the pressing part 212 of the pressing member 21 extends to the outside of the second chamber 12, and the components are pressed and fixed. The position of the sliding member 31 is maintained by the stopper 32, thereby ensuring the position of the pressing member 21. When it is necessary to contact and fix the components, the stopper 32 first contacts the limit of the sliding member 31, so that the sliding member 31 slides in the opposite direction, and the driving part 311 gradually releases the pressure on the abutting part 211, and the pressing member 21 is reset under the action of the elastic member 22, so that the pressing part 212 is retracted into the second chamber 12.
[0060] In a specific embodiment, the components in the box are fixed by the fixing device for a period of time, and then the components are fixed. After the components are fixed, the fixing of the components can be released, and then the fixing device can be removed from the box.
[0061] In another specific embodiment, the component fixing device in the box is always pressed and fixed. In this case, the fixing device needs to be fixed in the box, and the pressing and fixing of the component is released only when the component needs to be maintained or replaced.
[0062] like Figure 7 As shown, in some embodiments, the housing 1 includes a first portion 13 and a second portion 14 rotatably connected to the first portion 13 , the first chamber 11 is disposed in the first portion 13 , and the second chamber 12 is disposed in the second portion 14 .
[0063] In the present application, by configuring the first shell 1 to be composed of a first part 13 and a second part 14, the first part 13 and the second part 14 are rotatably connected, that is, the angle between the first direction X and the second direction Y can be changed, and the angle between the first direction X and the second direction Y can be adjusted according to the actual situation of the component installation position, thereby ensuring that components at different positions can be conveniently operated, and can be applicable to fixing more types of components.
[0064] Specifically, the driving portion 311 and the abutting portion 211 adopt a spherical structure or an arc surface structure, so that after the angle between the first direction X and the second direction Y changes, the driving portion 311 and the abutting portion 211 can still effectively cooperate to complete the movement of the pressing member 21.
[0065] In some embodiments, the first portion 13 and the second portion 14 are rotatably connected via a rotation shaft 15 , and the rotation shaft 15 is located in a communication area between the first chamber 11 and the second chamber 12 .
[0066] In the present application, the first part 13 and the second part 14 rotate through the rotating shaft 15, and the position of the rotating shaft 15 is located in the connecting area of the first chamber 11 and the second chamber 12, which can ensure that the first part 13 can effectively fit the driving part 311 and the abutting part 211 during the rotation around the rotating shaft 15, thereby ensuring that the sliding part 31 can effectively drive the clamping part 21 to slide.
[0067] In some embodiments, the housing 1 further includes a locking member 16 for locking the first portion 13 and the second portion 14 .
[0068] In the present application, the first part 13 and the second part 14 can be locked by setting a locking member 16 on the shell 1. After adjusting the angle between the first direction X and the second direction Y, the first part 13 and the second part 14 are locked by the locking member 16, and then the angle between the first direction X and the second direction Y is locked, which is convenient for operation to complete the compression and fixation of the components.
[0069] Specifically, the locking member 16 may be a screw, which is rotatably connected to the first portion 13, and the end of the screw abuts against the second portion 14. By tightening the screw, when the end of the screw fully abuts against the second portion 14, the first portion 13 and the second portion 14 are locked, and the angle between the first direction X and the second direction Y cannot be adjusted. If the angle between the first direction X and the second direction Y needs to be adjusted, the screw is loosened to separate the end of the screw from the second portion 14, and then the first portion 13 can be rotated around the rotation axis 15.
[0070] In some embodiments, the abutting portion 211 is a first wedge-shaped surface 2111 , and the driving portion 311 is a second wedge-shaped surface 3111 that slidably cooperates with the first wedge-shaped surface 2111 .
[0071] In the present application, the abutment portion 211 is a first wedge surface 2111, and the driving portion 311 is a second wedge surface 3111. Through the cooperation of the first wedge surface 2111 and the second wedge surface 3111, the sliding member 31 moves along the first direction X and pushes the clamping member 21 to move along the second direction Y, so that the sliding member 31 can drive the clamping member 21 to slide.
[0072] Specifically, by cooperating with the first wedge surface 2111 and the second wedge surface 3111, the driving portion 311 and the abutting portion 211 are in surface-to-surface contact, thereby increasing the contact area, making the force between the contact surfaces more even, reducing the damage caused by mutual squeezing between the driving portion 311 and the abutting portion 211, and extending their service life.
[0073] like Figure 8-10 As shown, in some embodiments, a slide groove 2112 is disposed on one of the first wedge surface 2111 and the second wedge surface 3111 , and a slider 3112 slidably disposed in the slide groove 2112 is disposed on the other one.
[0074] In a specific embodiment, a slide groove 2112 is provided on the first wedge surface 2111, and a slider 3112 is provided on the second wedge surface 3111. The slider 3112 is slidably provided in the slide groove 2112. When the sliding member 31 slides along the first direction X, it can drive the pressing member 21 to slide along the second direction Y, and make the pressing portion 212 of the pressing member 21 extend out of the second chamber 12; when the sliding member 31 slides in the opposite direction, the pressing member 21 can be driven to slide in the opposite direction through the cooperation of the slider 3112 and the slide groove 2112, so that the pressing portion 212 of the pressing member 21 is received in the second chamber 12. There is no need to provide an elastic member 22 to assist the pressing member 21 in resetting.
[0075] In another specific embodiment, a slide groove 2112 is provided on the second wedge surface 3111, and a slider 3112 is provided on the first wedge surface 2111. The slider 3112 is slidably provided in the slide groove 2112. When the sliding member 31 slides along the first direction X, it can drive the pressing member 21 to slide along the second direction Y, and make the pressing portion 212 of the pressing member 21 extend out of the second chamber 12; when the sliding member 31 slides in the opposite direction, the pressing member 21 can be driven to slide in the opposite direction through the cooperation of the slider 3112 and the slide groove 2112, so that the pressing portion 212 of the pressing member 21 is received in the second chamber 12. There is no need to provide an elastic member 22 to assist the pressing member 21 in resetting.
[0076] Optionally, when the abutment portion 211 is a first wedge-shaped surface 2111 and the driving portion 311 is a second wedge-shaped surface 3111, the elastic member 22 can still be used to assist the clamping member 21 in resetting. The principle is the same as when the driving portion 311 and the abutment portion 211 are spherical structures or arc structures, and will not be elaborated here.
[0077] like Figure 3 As shown, in some embodiments, the limiting member 32 is a bolt 321 rotatably connected to the housing 1 , and an end of the bolt 321 is rotatably connected to the sliding member 31 .
[0078] In the present application, the limit member 32 is a bolt 321, which extends in the direction of the first chamber 11. The bolt 321 is rotatably connected to the shell 1. By rotating the bolt 321, the bolt 321 can be driven to move axially, thereby causing the bolt 321 to drive the sliding member 31 to move.
[0079] Specifically, by rotating the bolt 321 in the forward direction, the bolt 321 can be driven to move in the direction of the clamping member 21, and then the sliding member 31 can be pushed to move in the direction of the clamping member 21, so that the driving portion 311 applies pressure to the abutting portion 211, so that the clamping member 21 moves in the direction away from the sliding member 31, so that the clamping portion 212 of the clamping member 21 extends out of the second chamber 12 to complete the clamping and fixing of the components. By rotating the bolt 321 in the reverse direction, the bolt 321 can be driven to move in the direction away from the clamping member 21, and then the sliding member 31 can be driven to move in the direction away from the clamping member 21, so that the clamping member can move toward the sliding member 31 under the action of the elastic member 22, and then the clamping portion 212 of the clamping member 21 is re-entered into the second chamber 12.
[0080] At this time, the housing 1 is provided with a threaded hole connected to the first chamber 11, the extension direction of the threaded hole is the same as the first direction X, and the bolt 321 is threadedly connected to the threaded hole. The end of the bolt 321 is connected to the rotatable rod of the sliding member 31, and the bolt 321 will not drive the sliding member 31 to slide, and can effectively drive the sliding member 31 to slide along the first chamber 11.
[0081] like Figure 4 As shown, in some embodiments, the limiting member 32 includes a screw tube 322 and a screw rod 323 that are threaded together. The screw tube 322 is rotatably connected to the housing 1 , and the screw rod 323 is connected to the sliding member 31 .
[0082] In the present application, the limiting member 32 can also be in the form of a screw tube 322 and a screw rod 323. The screw tube 322 and the screw rod 323 are connected by threads, the screw rod 323 is fixedly connected to the sliding member 31, and the screw tube 322 is rotatably connected to the shell 1. By rotating the screw tube 322, the screw rod 323 can be driven to move axially, and then the sliding member 31 can be driven to slide and move along the first direction X, thereby realizing the fixing or release of the components by the clamping member 21.
[0083] Specifically, at this time, the screw tube 322 is rotatably connected to the housing 1. When the screw tube 322 is rotated, the screw rod 323 does not rotate but only moves in the axial direction. Therefore, the screw rod 323 and the sliding member 31 only need to be fixedly connected.
[0084] like Figure 5As shown, in some embodiments, the limiting member 32 is a push rod 324 extending along the first direction X, one end of the push rod 324 is connected to the sliding member 31, and the other end is located outside the first chamber 11, and the push rod 324 is provided with a plurality of slots 3241 along its own axial direction, and the slots 3241 can be engaged with the shell 1 for fixing the sliding member 31.
[0085] In the present application, the push rod 324 extends along the first direction X, one end of the push rod 324 is located in the first chamber 11 and connected to the sliding member 31, and the other end is located outside the first chamber 11. The sliding member 31 is fixed by engaging with the shell 1 through the slot 3241. When the sliding member 31 needs to be moved, the engagement between the slot 3241 and the shell 1 can be released.
[0086] like Figure 6 As shown, in some embodiments, a through hole connected to the first chamber 11 is provided on the shell 1, and the push rod 324 passes through the through hole. The push rod 324 includes two relatively arranged arc shells 3242, and a compression gap is left between the two arc shells 3242. The card groove 3241 is provided on the outer surface of the arc shell 3242 for clamping the through hole.
[0087] In the present application, the push rod 324 uses two arc-shaped shells 3242, which are arranged opposite to each other, and a compression gap is arranged between the two arc-shaped shells 3242. When the two arc-shaped shells 3242 are pressed to move toward each other, the outer slots 3241 of the arc-shaped shells 3242 are separated from the perforations, thereby releasing the limit, and the push rod 324 can be automatically slid. When the two arc-shaped shells 3242 are released, the two arc-shaped shells 3242 are reset under the action of their own elastic force, so that the slots 3241 are again engaged with the perforations, completing the limit of the push rod 324 and the sliding member 31.
[0088] Optionally, an elastic member 22, such as an elastic sponge, may be provided between the two arc-shaped shells 3242 to assist the two arc-shaped shells 3242 in resetting, thereby ensuring the effect of the engagement between the card slot 3241 and the perforation.
[0089] The fixing device provided in the embodiment of the present application moves the sliding member 31 along the first chamber 11 so that the driving portion 311 of the sliding member 31 cooperates with the abutting portion 211 of the clamping member 21, thereby driving the clamping member 21 to slide along the second chamber 12, so that the clamping portion 212 of the clamping member 21 extends to the outside of the second chamber 12 and clamps the part to be fixed on the fixing surface, and then limits the sliding member 31 by the limiting member 32, so that the clamping member 21 remains in a state of fixing the part to be fixed. Even in a dense and delicate box, when the operating space above the fixing plate and the part to be fixed is limited, the part to be fixed can be fixed in the second direction Y by changing the direction of the operation, that is, by operating in the first direction X, thereby facilitating the effective fixation of components in the dense box and improving practicality.
[0090] In the related technology, the functions of the electric control box are increasing, while the size is getting smaller and smaller. The distance between the components in the electric control box is getting closer and closer. In the dense and delicate box, the operating space above the components is very limited. If you want to fix the components by rotating the screws with a screwdriver, the operation will be very inconvenient. Even if there are some right-angle screwdrivers that can complete the rotation of the screws in a smaller space, the angle of a single rotation is still limited, and it is still inconvenient to operate.
[0091] In the embodiment of the present application, by fixing the fixing device in the box and adjusting the position of the fixing device in the box, it is ensured that the part to be fixed can be effectively fixed, and the fixing device can be pre-set in the box according to the position of the component. When it is necessary to fix the component, the pressing member 21 can be made to slide along the second chamber 12 by operating the sliding member 31 of the fixing device, so that the pressing part 212 of the pressing member 21 extends out of the second chamber 12 and is pressed and fixed with the component. Even if the operating space above the component in the box is limited, it is still convenient to complete the fixing of the component.
[0092] An embodiment of the present application provides an electric control box, comprising: a box body; and the above-mentioned fixing device.
[0093] The functions of the electric control box are increasing, while the size is decreasing. The distance between the components in the electric control box is getting closer and closer. In the dense and delicate box, the operating space above the components is very limited. If you want to fix the components by rotating the screws with a screwdriver, the operation will be very inconvenient. Even though there are some right-angle screwdrivers that can complete the rotation of the screws in a smaller space, the angle of a single rotation is still limited, and it is still inconvenient to operate.
[0094] In the present application, by providing a fixing device in the box body of the electric control box, the direction of the force can be changed. Even if the operating space above the components is very small, the fixing of the components can still be facilitated by changing the direction of the force.
[0095] In some embodiments, the fixing device is fixedly disposed in the box; or the fixing device is detachably disposed in the box.
[0096] In a specific embodiment, the fixing device is fixedly arranged in the box, and the fixing device is used to fix the components for a long time. The fixing device is pre-fixed at the required position of the box according to the position of the components in the box. When it is necessary to fix the components, the sliding member 31 is slid along the first direction X, so that the driving part 311 of the sliding member 31 drives the pressing member 21 to move along the second direction Y, and then the pressing part 212 of the pressing member 21 presses and fixes the components; when it is necessary to maintain or replace the components, the sliding member 31 can be moved in the opposite direction to separate the pressing part 212 of the pressing member 21 from the components.
[0097] In another specific embodiment, the fixing device is detachably arranged in the box, and the fixing device is used to temporarily fix the components. For example, the components need to be pressed and kept in effective contact with the fixing surface in the early stage of fixing. After a period of time, the fixing device can be removed after the components are fully connected to the fixing surface. At this time, the fixing device is set in a detachable form, and it is only necessary to set a plane or structure that can fix the fixing device at a specific position of the box. For example, when it is necessary to press and fix a component on the top of the box, the fixing device can be fixed on the top of the box, and the fixing device is positioned to ensure that when the pressing member 21 of the fixing device slides along the second direction Y, the pressing part 212 of the pressing member 21 can effectively press and fix the component. After completing the pressing and fixing of the components, the fixing device can be removed. When it is necessary to press and fix a component at the bottom of the box, the fixing device can be fixed on the inner bottom wall of the box, and the fixing device is positioned to ensure that after the pressing member 21 of the fixing device slides along the second direction Y, the pressing part 212 of the pressing member 21 can effectively press and fix the component.
