The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 5, an embodiment of the present application discloses a vacant cover 100, and the vacant cover 100 can be applied to an electrical control device to cover part of electrical components in the electrical control device, so as to avoid damage to the electrical components due to long-term exposure and influence on appearance performance. Of course, the blank cover 100 may also be applied to other devices, and the application object and the application scenario of the blank cover 100 are not particularly limited in this embodiment of the application.

The disclosed blank cover 100 includes a blank cover body 110, a first snap feature 120, and a second snap feature 130. Wherein, vacancy lid body 110 is used for playing the effect of covering, and first joint structure 120 and second joint structure 130 all are used for playing the joint installation effect to install vacancy lid 100 to the device (e.g., mounting bracket 200 etc.) of waiting to cover, and also can convenient to detach.

Vacancy lid body 110 has first end and the second end that sets up along the first direction back to back, and first joint structure 120 sets up in first end, and second joint structure 130 sets up in the second end for first joint structure 120 and second joint structure 130 both are located vacancy lid body 110 along the both ends department of first direction respectively, so that make both ends department of vacancy lid body 110 with wait the device assembly that covers. In this case, the fitting region of the blank cover body 110 can be enlarged, and the fitting stability of the blank cover body 110 can be improved. Wherein the first direction may be a length direction or a width direction of the blank cover 100.

Optionally, the first end of the blank cover body 110 may be provided with a first snap structure 120 to reduce the complexity of the blank cover body 110, thereby reducing the manufacturing cost of the blank cover body 110; of course, a plurality of first clamping structures 120 may be arranged side by side to increase the assembly area between the device to be covered and the first clamping structures 120, thereby improving the firmness and stability of the assembly.

In some embodiments, the first snap structure 120 is provided with a snap groove 126 open towards the second end, which snap groove 126 can be snapped to the device to be covered when the blank cover 100 is installed, so as to achieve a snap fit. On this basis, can be convenient in the assembly between first joint structure 120 and the device that treats the cover, of course, still be favorable to making first joint structure 120 dismantle from the device that treats the cover, consequently, through the mode that adopts draw-in groove 126 joint, can make things convenient for the dismouting of vacancy lid 100, and then can improve the dismouting efficiency of vacancy lid 100.

The second clamping structure 130 has a free end that can be close to or far away from the first clamping structure 120 along the first direction, and a clamping protrusion 1311 is disposed on one side of the free end facing the first clamping structure 120. The latch 1311 is used to latch with a device to be covered, so as to facilitate the assembly and disassembly between the second end of the blank cover 100 and the device to be covered.

Alternatively, the second latch structure 130 may be an elastic deformation member (e.g., an elastic plastic member, etc.) having a certain elastic deformation amount, such that the second latch structure 130 can maintain an original state when not being subjected to an acting force, and can be deformed to make a free end thereof close to or far away from the first latch structure 120 when being subjected to the acting force. Thus, when the two ends of the vacancy cover 100 in the first direction are respectively clamped to the device to be covered through the first clamping structure 120 and the second clamping structure 130, under the action of the elastic force, the clamping groove 126 of the first clamping structure 120 and the clamping protrusion 1311 of the second clamping structure 130 are respectively and firmly clamped to the device to be covered, so that the firmness and stability of assembly between the vacancy cover 100 and the device to be covered can be improved; conversely, when the blank cover 100 needs to be removed, a force can be applied to the second latch structure 130 to move the free end and the latch 1311 thereon away from the latch slot 126, and to disengage the latch 1311 from the device to be covered, so that the blank cover 100 can be removed easily.

In order to facilitate the application of force to the second latch structure 130, in some embodiments, the free end is provided with a toggle portion, so that the force can be applied to the toggle portion to move the free end and the latch 1311 away from the first latch structure 120 to facilitate the removal of the blank cover 100.

Alternatively, the toggle portion may be a plug hole, a slot, or the like, so as to facilitate insertion of a toggle tool (i.e., a force application tool described below), thereby facilitating movement of a free end of the second latch structure 130 to facilitate detachment of the vacancy cover 100.

Based on the above setting, this application embodiment uses through the cooperation of first joint structure 120 and second joint structure 130, can firmly install vacancy lid 100 to the device that treats the cover to can be convenient for make second joint structure 130 break away from the device that treats the cover through applying effort to the stirring portion, thereby make things convenient for the dismantlement of vacancy lid 100. In addition, when vacancy cover 100 is installed to the device to be covered, the part that is exposed can be covered to prevent the part from being exposed and being affected by the outside and causing damage, the integrity of the part is ensured, and the appearance performance of the whole device to be covered can be improved under the condition that the vacancy cover 100 is covered, so that the experience of a user can be improved.

In some embodiments, the blank cover body 110 has a cavity 111 with an open end, and the first latch structure 120 and the second latch structure 130 are located in the cavity 111. It should be pointed out that the part that the device that waits to cover needs to cover may be partly protruding, can establish protruding part cover inside it through cavity 111, can provide accommodation space for protruding part on the one hand, and on the other hand can also prevent that protruding part from exposing to cover and the guard action has been played to protruding part, improved the outward appearance performance and the whole integrity of the device that waits to cover.

Meanwhile, the first clamping structure 120 and the second clamping structure 130 are located in the cavity 111 and do not need to be exposed, so that the installation area of the vacancy cover 100 can be covered, the appearance performance can be improved on one hand, and on the other hand, the situation that the installation area is accidentally tripped due to the fact that external factors interfere with the installation area can be prevented, and the installation stability of the vacancy cover 100 is guaranteed.

In order to facilitate the elastic deformation of the second clamping structure 130, the second clamping structure 130 may include a long plate 131 and a housing 132, wherein the long plate 131 is deformable, one end of the long plate 131 is connected to the wall surface of the cavity 111 at the end away from the opening, the long plate 131 extends toward the opening, the housing 132 is disposed at the end of the long plate 131 adjacent to the opening, and the housing 132 and the clamping protrusion 1311 are respectively located on two opposite sides of the long plate 131. It will be appreciated that the region of the housing 132 is relatively far from the junction of the second snap structure 130 and the blank cover body 110, such that the region of the housing 132 can be considered to be the free end of the second snap structure 130. When acting force is applied to the area where the shell 132 is located, the long plate 131 is easier to deform due to a large force arm, and the magnitude of the applied acting force can be reduced to a certain extent, so that the vacancy cover 100 can be detached only by applying relatively small acting force to the area where the shell 132 is located, and the vacancy cover 100 can be detached conveniently.

To facilitate the application of force to the free end of the second clamping structure 130, the housing 132 may be provided with an open slot 1321, and the open slot 1321 is a toggle portion at the free end. Thus, when the second clamping structure 130 is applied with an acting force, only the end of the force application tool needs to be inserted into the open slot 1321, and the acting force is applied to the housing 132 through the force application tool to pry the housing 132 to move, and meanwhile, under the driving of the housing 132, the long plate 131 generates bending deformation, so that the clamping protrusion 1311 is separated from the device to be covered, and the vacant site cover 100 is conveniently detached. Therefore, the open slot 1321 is arranged, so that the force application tool can be conveniently inserted or pulled out, the acting force applied by the force application tool can be borne, the vacancy cover 100 is not easy to damage, the disassembly frequency of the vacancy cover 100 can be increased, and the purpose of prolonging the service life of the vacancy cover 100 is achieved.

In order to facilitate the force application tool to be smoothly inserted into the open slot 1321 without being blocked, in some embodiments, the avoiding surface at the end of the cavity 111 facing away from the open slot may be provided with an avoiding hole 1111, and the avoiding hole 1111 is disposed opposite to the slot opening of the open slot 1321. Based on this, the force application tool can be inserted into the open slot 1321 after passing through the escape hole 1111, so that the efficiency of detaching the blank cover 100 by the force application tool can be improved, and in addition, the escape hole 1111 also has a guide function for the force application tool so that the force application tool can be accurately inserted into the open slot 1321.

In other embodiments, the notch of the open slot 1321 may face the side wall of the blank cover body 110, and the avoiding hole 1111 may be opened at the side wall of the blank cover body 110 and disposed opposite to the notch, in which case, the force applying tool may be inserted into the avoiding hole 1111 and inserted into the open slot 1321 to apply a force to the housing 132, so as to facilitate the detachment of the blank cover 100.

In order to prevent the second clamping structure 130 from being broken due to excessive deformation of the second clamping structure 130 under a force, in some embodiments, the blank cover 100 may further include a barrier structure 140, and the moving range of the free end may be limited by the barrier structure 140, wherein the barrier structure 140 is disposed on a side of the free end away from the first clamping structure 120. On this basis, when second joint structure 130 receives the effort that the application of force instrument was exerted, its free end orientation moves away from first joint structure 120's direction, and meanwhile, second joint structure 130 produces elastic deformation (i.e., long board 131 produces the deformation), at this moment, the free end receives the blocking (i.e., casing 132 receives the blocking) and unable continuation removal of shelves structure 140, and second joint structure 130 can not continue elastic deformation, thereby make second joint structure 130's elastic deformation can not exceed and predetermine the deflection (i.e., the biggest deflection that will take place the damage), and then guaranteed second joint structure 130's integrity.

In the embodiment of the present application, the barrier structure 140 can limit the moving range of the free end of the second clamping structure 130, so that the second clamping structure 130 is not excessively deformed, and therefore the second clamping structure 130 is not damaged, and the service life of the vacancy cover 100 can be prolonged.

In some embodiments, the first clamping structure 120 may include a first clamping surface 121, a second clamping surface 122 and a connecting surface 123 connecting the first clamping surface 121 and the second clamping surface 122, which are arranged at intervals along a second direction, wherein the second direction is perpendicular to the first direction, that is, the second direction is the thickness direction of the blank cover 100. Accordingly, the first clamping surface 121, the connecting surface 123 and the second clamping surface 122 together define a clamping groove 126 for clamping the device to be covered.

When the first clamping structure 120 is clamped and matched with a device to be covered, the first clamping surface 121 and the second clamping surface 122 can limit the device to be covered from two sides in the second direction, and the connecting surface 123 can limit the device to be covered from one side in the first direction, so that the limitation in multiple directions can be realized, the firmness and the stability between the first clamping structure 120 and the device to be covered are improved, and the first clamping structure 120 is prevented from being separated from the device to be covered.

In order to facilitate the clamping engagement of the clamping groove 126 of the first clamping structure 120 with the device to be covered, an end of the first clamping surface 121 adjacent to the connecting surface 123 may be provided with a recessed surface 124 recessed away from the second clamping surface 122, and the recessed surface 124 is disposed opposite to the second clamping surface 122. In this regard, when the end of the device to be covered is gradually moved into the card slot 126, the end of the device to be covered may be first inserted into the recessed space defined by the recessed surface 124, and then, as the blank cover 100 is rotated relative to the device to be covered, the end of the device to be covered may be moved in the recessed space, and finally, the end of the device to be covered may be restrained between the first and second engagement surfaces 121 and 122. Based on the above setting, through setting up sunken face 124, the one end that makes the device of waiting to cover can move and avoid producing the motion interference in the sunken space that sunken face 124 encloses to make vacancy lid 100 can rotate smoothly for the device of waiting to cover, and then can make vacancy lid 100 rotate to make second joint structure 130 with wait the other end joint cooperation of the device of covering, consequently can make vacancy lid 100 assemble smoothly with the device of waiting to cover.

In order to facilitate partial insertion of the device to be covered into the card slot 126, one end of the second clamping surface 122 departing from the connecting surface 123 is provided with an inclined guide surface 125, so that a flaring structure or an open structure is formed at the notch of the card slot 126, thereby increasing the cross-sectional area of the notch, and further facilitating partial insertion of the device to be covered into the card slot 126 to enable the first clamping structure 120 to be in clamping fit with the device to be covered.

In some embodiments, the vacancy cover 100 may further include a first limiting structure 150 and a second limiting structure 160, wherein the first limiting structure 150 is disposed at the first end of the vacancy cover body 110, and the second limiting structure 160 is disposed at the second end of the vacancy cover body 110, so that the first limiting structure 150 and the second limiting structure 160 may limit from both ends of the vacancy cover body 110, so as to improve the assembly accuracy and the assembly stability between the vacancy cover 100 and the device to be covered.

The first position-limiting structure 150 may have a first position-limiting surface 151 and a second position-limiting surface 152 that are perpendicular to each other, wherein the first position-limiting surface 151 is perpendicular to the first direction, and the second position-limiting surface 152 is opposite to the first engaging structure 120. Based on this, when vacancy lid 100 assembles to the device of waiting to cover, first spacing face 151 and second spacing face 152 all with wait each position looks butt of device that covers to can improve first limit structure 150 and wait the assembly precision between the device that covers, meanwhile, because first spacing face 151 and second spacing face 152 all receive the limiting displacement of waiting each part of device that covers, make first limit structure 150 can not remove for the device of waiting to cover, thereby guaranteed the stability of assembling between first limit structure 150 and the device of waiting to cover.

Similarly, the second position-limiting structure 160 has a third position-limiting surface 161 and a fourth position-limiting surface 162 that are perpendicular to each other, wherein the third position-limiting surface 161 is perpendicular to the first direction, and the fourth position-limiting surface 162 is opposite to the second engaging structure 130. Based on this, when vacancy lid 100 assembles to the device of waiting to cover, third spacing face 161 and fourth spacing face 162 all with wait each position looks butt of device that covers to can improve the assembly precision between second limit structure 160 and the device of waiting to cover, meanwhile, because third spacing face 161 and fourth spacing face 162 all receive the limiting displacement of each part of the device of waiting to cover, make second limit structure 160 can not remove for the device of waiting to cover, thereby guaranteed the stability of assembling between second limit structure 160 and the device of waiting to cover.
