Description

Technical Field

[0001] The present application relates to the technical field of electric control box layout, and in particular to an electric control box. Background Art

[0002] The existing electric control box usually includes a box body and a box cover. The box body is open at the top to form an opening, and the box cover is set on the opening to cover the opening, thereby closing the box body. A series of electrical components are arranged in the box body to form an electric control circuit. In the existing electric control box, sufficient space is required to arrange these electrical components, which requires the box body to provide sufficient arrangement space. However, when the box cover is opened to maintain the electric control box, the centralized arrangement of the electrical components makes it difficult to maintain the electric control box, which increases the maintenance time of the electric control box. Summary of the invention

[0003] In view of this, the present application provides an electric control box, the purpose of which is to solve the above technical problems to a certain extent.

[0004] In a first aspect, the present application provides an electric control box, the electric control box comprising:

[0005] An upper chassis and a lower chassis, wherein the upper chassis is located on the upper side of the lower chassis, and the upper chassis is rotatably connected to the lower chassis so that the upper chassis can swing in a horizontal plane relative to the lower chassis;

[0006] a locking mechanism, the locking mechanism being disposed on one of the lower surface of the upper chassis and the upper surface of the lower chassis, the locking mechanism comprising a movable locking member, the locking member having an unlocking position and a locking position relative to the one;

[0007] a plurality of stopper elements, the plurality of stopper elements being disposed on the other of the lower surface of the upper chassis and the upper surface of the lower chassis, the plurality of stopper elements being arranged along a trajectory of the upper chassis swinging relative to the lower chassis in the horizontal plane;

[0008] Each of the stop elements positions a swing position of the upper chassis relative to the lower chassis, and at the swing position, the corresponding stop element engages with the locking member at the locking position, and the corresponding stop element can also be disengaged from the locking member at the unlocking position;

[0009] Wherein, the upper case includes an upper case body and an upper case cover which are detachably connected, and also includes a first group of electrical components arranged in the upper case body; the lower case body includes a lower case body and a lower case cover which are detachably connected, and also includes a second group of electrical components arranged in the lower case body, and the lower case cover is configured to be removable from the lower case body along a horizontal direction. Preferably, the locking member has an extension direction and a hinge position in the middle of the extension direction, and the locking member is hinged to the one so as to rotate relative to the one around the hinge position, and the trajectory formed by the rotation includes the unlocking position and the locking position;

[0010] The locking member has a first end and a second end opposite to each other in the extending direction, the first end being used for engaging with the stop element, and the second end extending beyond an edge of the one in the horizontal direction when viewed along the vertical direction.

[0011] Preferably, the locking mechanism also includes a limiting member, which is connected to the one, and the limiting member includes a limiting accommodating portion, and the limiting accommodating portion has a first side and a second side opposite to each other, when the second end of the locking member abuts against the first side, the locking member is located in a locked position, and when the second end of the locking member abuts against the second side, the locking member is located in an unlocked position.

[0012] Preferably, the locking mechanism further comprises a reset member connecting the one and the locking member, the reset member being configured to apply force to the locking member to provide the locking member with a tendency to move from the unlocking position to the locking position.

[0013] Preferably, the support unit is connected to the upper case, and the support unit is retractable so as to extend and support the upper case when the upper case swings relative to the lower case; the support unit also supports the upper case when the upper case does not swing relative to the lower case.

[0014] Prior to the present application, some solutions have been proposed in the prior art for changing the layout of an electric control box. In these solutions, the change of the layout of the electric control box is also concentrated on adjusting the position of a part of the electrical components relative to the position of another part of the electrical components. Such position adjustment is usually also performed by installing the electrical components in different housings and then changing the relative position relationship between the housings.

[0015] However, although simply adjusting the position of the shell brings about a change in the layout of the electric control box, the maintenance operations performed when the layout of the electric control box is changed may take up to several hours, which requires the electric control box to maintain the changed layout for a long time, and different shells may be deformed during long-term maintenance due to the changed layout.

[0016] Before the present application was submitted, the deformation of the shell did not attract much attention from technicians in this field, because the deformation of the shell would often only cause slight abnormalities in the relative movement of the shell, but overcoming this abnormality would usually only cause sluggishness in the relative movement of the shell, which would require the operator to apply greater operating force to overcome it.

[0017] However, the inventor of the present application realizes that the deformation of the shell not only causes the movement of the shell, but also causes the position and shape of the electrical components arranged in the shell to change due to the deformation of the shell. Such changes in the position and shape of the electrical components will cause the performance of the electric control box to decrease, and even cause the electric control box to malfunction and fail. The support unit provided by the electric control box according to the present application can well avoid the problem of shell deformation.

[0018] Preferably, the supporting unit comprises:

[0019] A first shaft and a second shaft, wherein the first shaft is sleeved on the outer side of the second shaft, the first shaft has a first limiting groove and a second limiting groove spaced apart in the axial direction of the first shaft, and the first shaft also has a connecting groove extending along the axial direction of the first shaft, the connecting groove connecting the first limiting groove and the second limiting groove;

[0020] A guide pin, wherein the guide pin is connected to the second shaft, the guide pin can be clamped in the first limiting groove, and can enter the connecting groove and then enter the second limiting groove along with the rotation of the second shaft and the axial movement of the second shaft relative to the first shaft, and the guide pin can be clamped in the second limiting groove.

[0021] Preferably, the support unit further comprises:

[0022] A sleeve, wherein the sleeve is sleeved on the outer side of the first shaft;

[0023] An elastic member is disposed in a compressed form between the sleeve and the first shaft to provide the first shaft with a tendency to move into the sleeve.

[0024] Preferably, the support unit further comprises a force member, which is disposed on the upper side of the first shaft, movably connected to the sleeve, and capable of moving downward relative to the sleeve to abut against the first shaft, so that the first shaft and the second shaft move downward together.

[0025] Preferably, the lower chassis includes a rotating shaft connected to the bottom of the lower case body, and the upper chassis includes a sleeve portion connected to the upper case body, and the sleeve portion is sleeved on the outside of the rotating shaft so that the upper chassis can swing relative to the lower chassis.

[0026] Preferably, the rotating shaft is detachably connected to the bottom of the lower box.

[0027] According to the electric control box provided by the present application, in practical applications, the relative position of the upper box body relative to the lower box body can be changed by swinging the upper box body relative to the lower box body, thereby changing the layout of the electric control box. That is, as an electric control box, a first group of electrical components and a second group of electrical components can be respectively arranged in the upper box body and the lower box body. In practical applications, when it is necessary to maintain the electrical components in the electric control box, the layout of the electric control box can be adjusted according to actual needs.

[0028] For example, when only the electrical components in the upper chassis need to be maintained, the upper chassis can be kept in the initial state of being located above the lower chassis and not rotated, and the upper chassis cover can be removed from the upper chassis body to expose the first group of electrical components in the upper chassis for maintenance operations on these electrical components. When the electrical components in the lower chassis need to be maintained, the upper chassis can be rotated relative to the lower chassis, so that the upper chassis exposes the lower chassis after the rotation, and then the lower chassis cover can be removed from the lower chassis body in the horizontal direction to expose the second group of electrical components in the lower chassis.

[0029] Depending on the swing angle of the upper chassis relative to the lower chassis, the exposed area of ​​the second group of electrical components is also different. As the upper chassis passes through the above-mentioned multiple stop elements in sequence, the exposed area of ​​the second group of electrical components gradually increases, that is, the part blocked by the upper chassis gradually decreases, so as to adapt to the different maintenance requirements of the electrical components in the lower chassis.

[0030] The electric control box provided by the present application is relative to the electric control box using a separate box in the prior art. Since two boxes are used to respectively set two groups of electrical components, the depth of the two boxes can be smaller, and the layout complexity of the electrical components inside each box will also be lower. Compared with the existing separate boxes, the operation difficulty inside the box during maintenance is lower, which is more conducive to improving the working efficiency.

[0031] According to the electric control box provided in the present application, a locking mechanism and a plurality of stop elements cooperating with the locking mechanism are provided, so that the corresponding position of the upper chassis relative to the lower chassis is obtained by utilizing the cooperation between the locking mechanism and each stop element. Thus, on the basis of changing the layout of the electric control box as above, according to the electric control box provided in the embodiment of the present application, a locking mechanism and a plurality of stop elements cooperating with the locking mechanism are utilized to give the position of each upper box body relative to the lower box body, that is, the layout of each electric control box is in a stable state, thereby ensuring that in actual applications, the electric control box has both multiple layouts and a stable layout state.

[0059] In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0060] According to an embodiment of the present application, an electric control box is provided. The structure and working principle of the electric control box will be described in detail below with reference to the accompanying drawings.

[0061] According to the electric control box provided in the embodiment of the present application, the electric control box includes an upper chassis, a lower chassis, a locking mechanism and a plurality of stop elements. In the embodiment, the upper chassis is located on the upper side of the lower chassis, and the upper chassis is rotatably connected to the lower chassis so that the upper chassis can swing in a horizontal plane relative to the lower chassis. The locking mechanism is provided on one of the lower surface of the upper chassis and the upper surface of the lower chassis, and the locking mechanism includes a movable locking member, and the locking member has an unlocking position and a locking position relative to one of them.

[0062] In an embodiment, the plurality of stop elements are disposed on the other of the lower surface of the upper chassis and the upper surface of the lower chassis, and the plurality of stop elements are arranged along a trajectory of the upper chassis swinging relative to the lower chassis in a horizontal plane.

[0063] In the embodiment, each stop element locates a swing position of the upper chassis relative to the lower chassis. In the swing position, the corresponding stop element engages with the locking member in the locking position, and the corresponding stop element can also disengage from the locking member in the unlocking position.

[0064] In an embodiment, the upper case includes an upper case body and an upper case cover that are detachably connected, and also includes a first group of electrical components disposed in the upper case body. The lower case body includes a lower case body and a lower case cover that are detachably connected, and also includes a second group of electrical components disposed in the lower case body, and the lower case cover is configured to be detachable from the lower case body along a horizontal direction.

[0065] Thus, according to the electric control box provided in the embodiment of the present application, in actual application, the relative position of the upper box body relative to the lower box body can be changed by swinging the upper box body relative to the lower box body, thereby changing the layout of the electric control box. That is to say, as an electric control box, in the embodiment of the present application, the first group of electrical components and the second group of electrical components can be respectively arranged in the upper box body and the lower box body. In actual application, when it is necessary to maintain the electrical components in the electric control box, the layout of the electric control box can be adjusted according to actual needs.

[0066] For example, when only the electrical components in the upper chassis need to be maintained, the upper chassis can be kept in the initial state of being located above the lower chassis and not rotated, and the upper chassis cover can be removed from the upper chassis body to expose the first group of electrical components in the upper chassis for maintenance operations on these electrical components. When the electrical components in the lower chassis need to be maintained, the upper chassis can be rotated relative to the lower chassis, so that the upper chassis exposes the lower chassis after the rotation, and then the lower chassis cover can be removed from the lower chassis body in the horizontal direction to expose the second group of electrical components in the lower chassis.

[0067] In an embodiment, the exposed area of ​​the second group of electrical components varies according to the different swing angles of the upper chassis relative to the lower chassis. As the upper chassis passes through the above-mentioned multiple stop elements in sequence, the exposed area of ​​the second group of electrical components gradually increases, that is, the part blocked by the upper chassis gradually decreases, so as to adapt to the different maintenance requirements of the electrical components in the lower chassis.

[0068] In an embodiment, the electric control box provided according to the embodiment of the present application, relative to the electric control box using a separate box in the prior art, because two boxes are used to respectively set two groups of electrical components, the depth of the two boxes can be smaller, and the layout complexity of the electrical components inside each box will also be lower. Compared with the existing separate boxes, the operation difficulty inside the box during maintenance is lower, which is more conducive to improving work efficiency.

[0069] In an embodiment, according to the electric control box provided in the embodiment of the present application, a locking mechanism and a plurality of stop elements cooperating with the locking mechanism are provided, so that the position of the corresponding upper chassis relative to the lower chassis is obtained by utilizing the cooperation between the locking mechanism and each stop element. Thus, on the basis of changing the layout of the electric control box as above, according to the electric control box provided in the embodiment of the present application, a locking mechanism and a plurality of stop elements cooperating with the locking mechanism are utilized to give the position of each upper box body relative to the lower box body, that is, the layout of each electric control box is in a stable state, thereby ensuring that in actual applications, the electric control box has both multiple layouts and a stable layout state.

[0070] In the embodiment, as an example, the above-mentioned multiple stop elements can form an arc track, for example, which is actually an arc track formed by the upper chassis swinging around the axis in the horizontal plane.

[0071] In an embodiment, the upper chassis and the lower chassis may present a rectangular parallelepiped or a substantially rectangular parallelepiped structure as a whole. As an example, when viewed from above in the vertical direction, the axis of rotation of the upper chassis relative to the lower chassis may be located at one corner of the upper chassis, and the subsequent support unit may be located at another corner opposite to the corner. In an embodiment, arranging the rotation axis of the upper chassis at a corner is conducive to ensuring that the upper chassis moves away from the lower chassis with the maximum displacement relative to the lower chassis during the swinging process, thereby more effectively changing the layout of the electric control box.

[0072] As an example, the locking mechanism may be disposed on the lower surface of the upper chassis, and the aforementioned multiple stop elements may be disposed on the upper surface of the lower chassis. In the embodiment, it will also be mentioned in the subsequent description that the number of stop elements may be, for example, three, corresponding to the initial position where the upper chassis is completely above the lower chassis, and two positions where the upper chassis is swung relative to the lower chassis, wherein, Figure 2A As shown, the stop element located in the middle can allow the upper chassis to rotate 45 degrees, and the stop element located at the outermost side can allow the upper chassis to rotate 90 degrees.

[0073] In an embodiment, the lower case cover can be pulled out from above the lower case body in a horizontal direction. For example, after the upper case is in place, the locking mechanism and the corresponding stopper element can be unlocked, and then the lower case cover can be pulled out in a manner that does not interfere with the upper case and the locking mechanism. In other examples not shown, the lower case cover can also be a spliced ​​structure formed by multiple panels, and adjacent panels can be matched through step surfaces or protrusions and recesses, and different panels can be pulled out to expose the electrical components below.

[0074] According to the electric control box provided in the embodiment of the present application, the locking member may have an extension direction and a hinge position in the middle of the extension direction. The locking member is hinged to the lower surface of the upper chassis so as to rotate around the hinge position relative to the lower surface of the upper chassis. The trajectory formed by the rotation includes an unlocking position and a locking position.

[0075] In an embodiment, by hingedly connecting the locking member to the lower surface of the upper chassis, the locking member can move relative to the upper chassis in a swinging manner, so that the unlocking position and the locking position of the locking member are easier to determine and switch. In an embodiment, as an example, the locking member can be a sheet-like structure, and when the locking member of the sheet-like structure is in the locked position, it can extend in its entirety or in large part along the width direction of the upper chassis.

[0076] In an embodiment, the locking member may have a first end and a second end opposite to each other in the extension direction, the first end being used to engage with the stop element, and the second end being beyond the edge of the upper chassis in the horizontal direction when viewed along the vertical direction. In an embodiment, as an example, the first end of the locking member may have a groove, and the stop element mentioned in the above description may be a pin, and the pin may be stuck in the groove. And the operator may tilt the locking member by toggling the second end of the locking member beyond the edge of the upper chassis, thereby disengaging from the pin, and contacting the locking of the upper chassis.

[0077] According to the electric control box provided in the embodiment of the present application, the locking mechanism may further include a limiting member, the limiting member may be connected to one, the limiting member may include a limiting accommodating portion, the limiting accommodating portion may have a first side and a second side opposite to each other, when the second end of the locking member may abut against the first side, the locking member is located in a locked position, and when the second end of the locking member may abut against the second side, the locking member is located in an unlocked position.

[0078] In an embodiment, as an example, the limiting accommodating portion may be, for example, a U-shaped component fixed to the lower surface of the upper chassis, and the first side and the second side may be two parts included in the inner side of the limiting component, specifically two parts opposite to each other in the length direction of the upper chassis.

[0079] According to the electric control box provided in the embodiment of the present application, the locking mechanism further includes a reset member, the reset member is connected to the locking member, and the reset member is configured to apply force to the locking member to provide the locking member with a tendency to move from the unlocked position to the locked position. As an example, according to the electric control box provided in the embodiment of the present application, the reset member can be, for example, a spring, and the elastic force applied by the spring can make the locking member reset to the locked position after being manually unlocked by the operator, so as to ensure the stability of the layout of the electric control box.

[0080] According to the electric control box provided in the embodiment of the present application, the upper chassis may further include a support unit and an upper box body, the support unit may be connected to the upper box, and the support unit may be retractable so as to extend when the upper chassis swings relative to the lower chassis and support the upper box body. In addition, in the embodiment, the support unit also supports the upper box body when the upper chassis does not swing relative to the lower chassis. In this way, according to the electric control box provided in the embodiment of the present application, the stability of the electric control box after the layout is changed can be increased by the support unit.

[0081] In the embodiment, it will be mentioned in the subsequent description that three points corresponding to the initial position, the first rotation position and the second rotation position of the upper chassis are configured for the support unit, wherein point 1 is located on the upper end surface of the lower case cover of the lower case, and points 2 and 3 are located on the bottom plate. In the embodiment, a corresponding support concave hole is provided at each point, and the support concave hole can be inserted into the lower end of the support rod of the support unit, thereby limiting the lower end of the support rod.

[0082] In the embodiment, the limiting and locking mechanism of the supporting recess cooperates with the limiting of the corresponding stop element to achieve double limiting of the upper chassis at each position of the initial position, the first rotation position and the second rotation position, which is beneficial to further improve the stability of the electric control box.

[0083] According to the electric control box provided in the embodiment of the present application, the support unit may further include: a first shaft and a second shaft, the first shaft being sleeved on the outside of the second shaft, the first shaft having a first limiting groove and a second limiting groove spaced apart in the axial direction of the first shaft, the first shaft also having a connecting groove extending along the axial direction of the first shaft, the connecting groove connecting the first limiting groove and the second limiting groove.

[0084] According to the electric control box provided in the embodiment of the present application, the support unit may further include a guide pin, which may be connected to the second shaft. The guide pin can be clamped in the first limiting groove and can enter the connecting groove and then enter the second limiting groove along with the rotation of the second shaft and the axial movement of the second shaft relative to the first shaft, and the guide pin can be clamped in the second limiting groove.

[0085] According to the electric control box provided in the embodiment of the present application, the support unit may further include a sleeve and an elastic member. In the embodiment, the sleeve may be sleeved on the outside of the first shaft, and the elastic member may be arranged between the sleeve and the first shaft in a compressed form to provide the first shaft with a tendency to move into the sleeve. In the embodiment, according to the electric control box provided in the embodiment of the present application, when the first shaft is received in the sleeve, the support unit may be substantially separated from the support surface below, thereby facilitating the swing of the upper box body relative to the lower box body. As an example, the elastic member may also be, for example, a spring.

[0086] In the embodiment, both the first limiting groove and the second limiting groove can be bolt grooves, for example, and the extension direction of the two is spiral downward. As an example, the first limiting groove and the second limiting groove can be connected to the vertical connecting groove in the same way. Taking the first limiting groove as an example, the first limiting groove has two ends, one end is connected to the connecting groove, and the other end is the end of the groove, which is used to limit the guide pin. In the embodiment, the spiral downward extension method makes the height of the end of the first limiting groove lower than the height of the end connected to the connecting groove. In this way, when the guide pin is located at the end of the first limiting groove, due to the spiral downward structure of the first limiting groove, the guide pin will not move and enter the connecting groove, thereby improving the stability of the support unit. Similarly, the structure of the second limiting groove is the same, which will not be repeated here.

[0087] In an embodiment, according to the electric control box provided in the embodiment of the present application, the upper chassis is supported by a support unit, which can improve the stability of the electric control box after the layout is changed, thereby avoiding deformation of the upper chassis and the lower chassis and providing more time for the maintenance of the electric control box.

[0088] According to the electric control box provided in the embodiment of the present application, the support unit may further include a force member, the force member is disposed on the upper side of the first shaft, the force member may be movably connected to the sleeve, and the force member may move downward relative to the sleeve to abut against the first shaft, so that the first shaft and the second shaft move downward together. In an embodiment, according to the electric control box provided in the embodiment of the present application, the force member is manually adjusted by an operator to press the first shaft out of the sleeve.

[0089] According to the electric control box provided in the embodiment of the present application, the lower case may include a lower case body and a rotating shaft connected to the bottom of the lower case body, and the upper case may include an upper case body and a sleeve portion connected to the upper case body, and the sleeve portion may be sleeved on the outer side of the rotating shaft so that the upper case can swing relative to the lower case. In the embodiment, the sleeve portion may still be a sleeve.

[0090] According to the electric control box provided in the embodiment of the present application, the rotating shaft and the bottom of the lower box body can be detachably connected by means such as screws.

[0091] Based on the above description, the electric control box will be explained below in conjunction with a specific example of the electric control box.

[0092] According to the embodiment of the present application, a chassis with swing positioning and locking is substantially provided, which specifically comprises: a bottom plate 3, a lower chassis 2 fixed on the bottom plate 3, and an upper chassis 1 placed on the lower chassis 2 and swinging around the lower chassis 2.
