Description

Technical Field

[0001] This application relates to the technical field of hanging installation, and particularly to a wall-mounted device and an inverter device. Background Art

[0002] In order to facilitate the use of equipment and reduce the occupied space of the equipment, people will use wall-mounted components to hang the equipment. For example, a TV is hung on a wall through a wall-mounted component, and an inverter device is hung on a wall / carriage through a wall-mounted component.

[0003] However, when the equipment is hung and installed, due to the obstruction of the equipment, it is difficult for the user to observe the situation between the equipment and the wall. This makes it difficult for the user to quickly align the fixing holes on the equipment with the fixing holes on the wall, which is not convenient for subsequent fixing parts such as screws to pass through the fixing holes to lock the equipment and the wall, reducing the installation efficiency of the equipment. Summary of the Utility Model

[0004] In view of this, this application provides a wall-mounted device and an inverter device to improve the technical problem that the existing wall-mounted device is difficult to quickly align and has low installation efficiency.

[0005] An embodiment of this application provides a wall-mounted device. The wall-mounted device includes a first connecting frame and a second connecting frame. The first connecting frame is configured to be connected to an external device, and the second connecting frame is configured to be installed on a target object. The first connecting frame and the second connecting frame are connected, and the first connecting frame and the second connecting frame can slide relative to each other. The first connecting frame is provided with a first hole and a first alignment part, and the second connecting frame is provided with a second hole and a second alignment part. The first alignment part and the second alignment part are engaged with each other to restrict the relative position of the first connecting frame and the second connecting frame. The first hole and the second hole are configured to be aligned with each other when the first alignment part and the second alignment part are engaged with each other, and are configured to be able to cooperate with each other to fix the first connecting frame and the second connecting frame.

[0006] In the above wall-mounted device, since the first connecting frame and the second connecting frame can slide relative to each other, the user can easily push the external device when hanging the external device to perform the alignment installation operation, and the operation is more labor-saving. At the same time, during the relative sliding of the first connecting frame and the second connecting frame, the wall-mounted device can achieve the quick alignment of the first hole in the first connecting frame and the second hole in the second connecting frame through the engagement of the first alignment part and the second alignment part, so as to facilitate the cooperation of the first hole and the second hole, thereby fixing the first connecting frame and the second connecting frame, that is, completing the hanging installation of the external device and improving the installation efficiency of the equipment.

[0007] In some embodiments of the present application, the second alignment portion can move between a first position and a second position, and when the second alignment portion is in the first position, the second alignment portion is engaged with the first alignment portion to constrain the relative position of the first connecting frame and the second connecting frame. When the second alignment portion is in the second position, the second alignment portion is separated from the first connecting frame to release the constraint on the first connecting frame and the second connecting frame.

[0008] In the above embodiment, the wall-mounted device realizes the snap fit between the first alignment portion and the second alignment portion, or releases the snap fit between the first alignment portion and the second alignment portion, by moving the second alignment portion between the first position and the second position.

[0009] In some embodiments of the present application, the wall-mounted device further includes a rolling member, which is disposed between the first connecting frame and the second connecting frame and is rollingly connected to the first connecting frame and the second connecting frame.

[0010] In the above embodiment, the sliding friction between the first connecting frame and the second connecting frame can be converted into rolling friction by setting the rolling member. Compared with sliding friction, the friction force of rolling friction is smaller. Therefore, it can not only save effort for the user to push the external device, but also make the relative sliding of the first connecting frame and the second connecting frame smoother.

[0011] In some embodiments of the present application, the wall-mounted device further comprises a limit seat, which is mounted on the second connecting frame and forms a rolling space with the second connecting frame, and the rolling element is mounted in the rolling space. The limit seat or the second connecting frame is provided with a connecting port, which is connected to the rolling space and leads to the first connecting frame, and part of the rolling element is rotatably abutted against the first connecting frame through the connecting port, and the limit seat is configured to prevent the rolling element from leaving the rolling space.

[0012] In the above embodiment, the limit seat can ensure that the rolling element always rolls in the rolling space, thereby reducing the risk of the rolling element deviating during the rolling process, causing the first connecting frame and the second connecting frame to derail, thereby improving the safety and stability of the wall-mounted device.

[0013] In some embodiments of the present application, when the limiting seat is provided with a communication port, the second connecting frame is provided with a positioning port, the positioning port is communicated with the rolling space, and the rolling element is partially exposed to the outside of the rolling space through the positioning port. When the second connecting frame is provided with a communication port, the limiting seat is provided with a positioning port, the positioning port is communicated with the rolling space, and the rolling element is partially exposed to the outside of the rolling space through the positioning port.

[0014] In the above embodiment, when assembling the rolling element and the limit seat, the positioning port can position and limit the rolling element to reduce the risk of slippage and misalignment of the rolling element and the limit seat during the assembly process, thereby facilitating the user to align the rolling element with the positioning port and install the limit seat on the second connecting frame, thereby improving the assembly efficiency of the wall-mounted device.

[0015] In some embodiments of the present application, the first connecting frame has a rolling surface, the second connecting frame has a mounting surface, the rolling surface and the mounting surface are arranged opposite to each other, and the rolling member rotates and abuts against the rolling surface. Along the direction from the mounting surface towards the rolling surface, when the second alignment portion is in the first position, the height by which the second alignment portion protrudes from the mounting surface is greater than the height by which the rolling member protrudes from the mounting surface.

[0016] In the above embodiments, by setting the height by which the second alignment portion protrudes from the mounting surface to be greater than the height by which the rolling member protrudes from the mounting surface, the stability of the engagement between the second alignment portion and the first alignment portion when the second alignment portion is in the first position is improved, which is conducive to ensuring the engagement and cooperation between the second alignment portion and the first alignment portion, and realizing the alignment of the first hole in the first connecting frame and the second hole in the second connecting frame.

[0017] In some embodiments of the present application, a first direction is defined to be parallel to the sliding direction of the first connecting frame and the second connecting frame, and a second direction is defined to intersect the first direction. The first connecting frame includes a first mounting member and a second mounting member, the first mounting member and the second mounting member are configured to be spaced apart along the second direction and mounted on an external device, the first mounting member is provided with a first alignment portion, and the second mounting member is provided with a first hole. The second connecting frame includes a third mounting member and a fourth mounting member, the third mounting member and the fourth mounting member are configured to be spaced apart along the second direction and mounted on an object, the third mounting member is provided with a second alignment portion, and the fourth mounting member is provided with a second hole. When the first alignment portion and the second alignment portion are engaged and cooperate, the axes of the first hole and the second hole coincide.

[0018] In the above embodiments, the engagement positions of the first alignment portion and the second alignment portion and the connection positions of the first hole and the second hole are distributed in the second direction, which is conducive to improving the connection stability of the first connecting frame and the second connecting frame in the second direction.

[0019] In some embodiments of the present application, a third direction is defined to intersect the first direction and the second direction respectively. When the second connecting frame is mounted on the object, an assembly space is formed between the third mounting member and the object along the third direction. The wall-mounted device further includes a guiding member, the guiding member is connected to the first mounting member, and the guiding member is inclined with respect to the third direction. The guiding member is configured to be inserted into the assembly space along the second direction when the first connecting frame is assembled to the object.

[0020] In the above embodiments, the first connecting frame can be inserted into the assembly space through the guiding of the guiding member to realize the connection between the first connecting frame and the second connecting frame. At the same time, since the guiding member is inclined, the guiding member can increase the insertion angle between the first connecting frame and the second connecting frame, so that the first connecting frame is more easily inserted into the assembly space, thereby improving the connection efficiency between the first connecting frame and the second connecting frame.

[0021] In some embodiments of the present application, the first connecting bracket is provided with a first locking portion, and the second connecting bracket is provided with a second locking portion. When the first alignment portion and the second alignment portion are engaged in a snap-fit manner, the first locking portion and the second locking portion are aligned and configured to be able to connect to each other to fix the first connecting bracket and the second connecting bracket.

[0022] In the above embodiments, by providing the first locking portion and the second locking portion, secondary fixation can be performed on the basis of the hole connection to improve the fixing stability and safety of the connection between the first connecting bracket and the second connecting bracket, and it is also beneficial to prevent others from casually disassembling the external device.

[0023] In some embodiments of the present application, the first connecting bracket is provided with a guiding groove, and the second connecting bracket is configured to slide relative to the first connecting bracket along the guiding groove.

[0024] In the above embodiments, the guiding groove can play a guiding role in the relative sliding of the first connecting bracket and the second connecting bracket, reducing the risk that the first hole and the second hole cannot be accurately aligned due to the deviation of the relative sliding of the first connecting bracket and the second connecting bracket, which is beneficial to ensuring the precise alignment of the external device with the target.

[0025] In some embodiments of the present application, the first connecting bracket is further provided with a stopper. The stopper is arranged at both ends of the guiding groove along the sliding direction of the first connecting bracket and the second connecting bracket. The stopper is configured to stop the second connecting bracket when the first connecting bracket and the second connecting bracket slide relative to each other, so as to restrict the range of relative movement of the first connecting bracket and the second connecting bracket.

[0026] In the above embodiments, by providing the stopper, the range of relative movement of the first connecting bracket and the second connecting bracket can be restricted, reducing the risk that the first connecting bracket and the second connecting bracket are disengaged due to the excessive relative movement distance of the first connecting bracket and the second connecting bracket, and further improving the stability and safety of the wall-mounted device.

[0027] An embodiment of the present application provides an inverter device. The inverter device includes a host and a wall-mounted device as described in any of the above embodiments, and the host is connected to the wall-mounted device.

[0028] In the above inverter device, by adopting the above wall-mounted device, not only the operation is more labor-saving, but also the hanging installation efficiency of the inverter device can be improved. Exemplarily, in the wall-mounted device, since the first connecting bracket and the second connecting bracket can slide relative to each other, the user can easily push the external device when hanging the external device to perform the alignment installation operation. At the same time, during the relative sliding of the first connecting bracket and the second connecting bracket, the wall-mounted device can achieve the rapid alignment of the first hole in the first connecting bracket and the second hole in the second connecting bracket through the snap-fit of the first alignment portion and the second alignment portion, so as to facilitate the connection of the first hole and the second hole, thereby fixing the first connecting bracket and the second connecting bracket.

[0049] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific implementation manners, and are not intended to limit this application.

[0051] To facilitate the use of the device and at the same time reduce the occupied space of the device, people will use a wall - hanging component to hang the device. For example: hanging a TV on the wall through the wall - hanging component, hanging an inverter device on the wall / carriage through the wall - hanging component.

[0052] However, when the device is hung and installed, due to the obstruction of the device, it is difficult for the user to observe the situation between the device and the wall. This results in that it is difficult for the user to quickly align the fixing holes on the device with the fixing holes on the wall, which is not convenient for subsequent fixing parts such as screws to pass through the fixing holes to lock the device and the wall, thus reducing the installation efficiency of the device.

[0053] An embodiment of the present application provides a wall - hanging device. The wall - hanging device includes a first connecting frame and a second connecting frame. The first connecting frame is configured to be connected to an external device, and the second connecting frame is configured to be installed on a target object. The first connecting frame and the second connecting frame are connected, and the first connecting frame and the second connecting frame can slide relative to each other. The first connecting frame is provided with a first hole and a first alignment part, and the second connecting frame is provided with a second hole and a second alignment part. The first alignment part and the second alignment part are in snap - fit to restrict the relative position of the first connecting frame and the second connecting frame. The first hole and the second hole are configured to be aligned with each other when the first alignment part and the second alignment part are in snap - fit, and are configured to be able to cooperate with each other to fix the first connecting frame and the second connecting frame.

[0054] In the above-mentioned wall-mounted device, since the first connecting frame and the second connecting frame can slide relative to each other, when a user hangs an external device, the user can easily push the external device to perform the alignment installation operation, which is more labor-saving. At the same time, during the relative sliding of the first connecting frame and the second connecting frame, the wall-mounted device can achieve the quick alignment of the first hole in the first connecting frame and the second hole in the second connecting frame through the snap-fit of the first alignment portion and the second alignment portion, so as to facilitate the cooperation between the first hole and the second hole, thereby fixing the first connecting frame and the second connecting frame, that is, completing the hanging installation of the external device and improving the installation efficiency of the device.

[0055] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0056] An embodiment of the present application provides a wall-mounted device 100, and the wall-mounted device 100 is used to mount an external device 200 on a target 300.

[0057] In some embodiments, the external device 200 may be a device that needs to be hung, such as an energy storage device, an inverter device, a television, etc. The energy storage device has the functions of storing and discharging electricity for household power backup, production unit power backup, outdoor operations, outdoor entertainment, etc. The energy storage device includes a power conversion module (not shown in the figure). The power conversion module is disposed inside the housing. The housing protects the power conversion module. The power conversion module is electrically connected to the battery pack. The power conversion module is used to realize the AC-DC conversion control of the output current of the battery pack. The energy storage device provided with the power conversion module may be a small portable mobile power supply, a household energy storage power supply, an industrial and commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0058] In some embodiments, the power conversion module may be omitted. The energy storage device without the power conversion module can be used independently. The energy storage device without the power conversion module usually can only output direct current. When the energy storage device without the power conversion module is used independently, it can be used in coordination with the energy storage device provided with the power conversion module as a power system for providing additional battery capacity.

[0059] In some embodiments, the target 300 may be a wall, a carriage wall, etc.

[0060] In some embodiments, as Figure 1 , Figure 2 and Figure 3 shown, the wall-mounted device 100 includes a first connecting frame 10 and a second connecting frame 20. The first connecting frame 10 is configured to be connected to the external device 200, and the second connecting frame 20 is configured to be fixed to the target 300.

[0061] In some embodiments, the first connecting bracket 10 is mounted on the external device 200 through fixing members (specifically threaded members such as screws and bolts), and the second connecting bracket 20 is fixed to the target object 300 through fixing members, which is beneficial for subsequent disassembly of the first connecting bracket 10 and the second connecting bracket 20 for replacement or repair.

[0062] In other embodiments, the first connecting bracket 10 and the second connecting bracket 20 may also adopt other fastening connection methods such as bonding and welding, and the present application does not limit this.

[0063] In some embodiments, the first connecting bracket 10 and the second connecting bracket 20 are connected, and the first connecting bracket 10 and the second connecting bracket 20 can slide relative to each other. The first connecting bracket 10 is provided with a first hole 121 and a first alignment portion 111, and the second connecting bracket 20 is provided with a second hole 221 and a second alignment portion 211. The first alignment portion 111 and the second alignment portion 211 are engaged and matched to restrict the relative positions of the first connecting bracket 10 and the second connecting bracket 20. The first hole 121 and the second hole 221 are configured to be aligned with each other when the first alignment portion 111 and the second alignment portion 211 are engaged and matched, and are configured to be able to cooperate with each other to fix the first connecting bracket 10 and the second connecting bracket 20.

[0064] Exemplarily, when hanging the external device 200, the user first connects the first connecting bracket 10 to the external device 200 and fixes the second connecting bracket 20 to the target object 300. Subsequently, the first connecting bracket 10 connected to the external device 200 is connected to the second connecting bracket 20, and the external device 200 is pushed to make the first connecting bracket 10 slide relative to the second connecting bracket 20.

[0065] When the first alignment portion 111 and the second alignment portion 211 are engaged and matched, the first alignment portion 111 and the second alignment portion 211 jointly restrict the relative positions of the first connecting bracket 10 and the second connecting bracket 20. At this time, the first hole 121 in the first connecting bracket 10 and the second hole 221 in the second connecting bracket 20 are aligned with each other, and the user connects the first hole 121 and the second hole 221 through a fixing member to fix the first connecting bracket 10 and the second connecting bracket 20, and the hanging installation of the external device 200 can be completed.

[0066] It can be understood that since the first connecting bracket 10 and the second connecting bracket 20 can slide relative to each other, the user can easily push the external device 200 when hanging the external device 200 for alignment installation operation, and the operation is more labor-saving.

[0067] Meanwhile, during the relative sliding of the first connecting bracket 10 and the second connecting bracket 20, the wall-mounted device 100 can achieve the rapid alignment of the first hole 121 in the first connecting bracket 10 and the second hole 221 in the second connecting bracket 20 through the snap-fit of the first alignment portion 111 and the second alignment portion 211, so as to facilitate the cooperation between the first hole 121 and the second hole 221, thereby fixing the first connecting bracket 10 and the second connecting bracket 20, that is, completing the hanging installation of the external device 200 and improving the installation efficiency of the device.

[0068] In some embodiments, such as Figure 4 and Figure 5 shown, the second alignment portion 211 can move between a first position and a second position. When the second alignment portion 211 is in the first position, the second alignment portion 211 is snap-connected to the first alignment portion 111 to restrict the relative positions of the first connecting bracket 10 and the second connecting bracket 20. When the second alignment portion 211 is in the second position, the second alignment portion 211 is separated from the first connecting bracket 10 to release the restriction on the first connecting bracket 10 and the second connecting bracket 20.

[0069] The wall-mounted device 100 realizes the snap-fit between the first alignment portion 111 and the second alignment portion 211, or releases the snap-fit between the first alignment portion 111 and the second alignment portion 211 by moving the second alignment portion 211 between the first position and the second position.

[0070] In some embodiments, when the second alignment portion 211 is in the second position compared with the first position, the volume of the second alignment portion 211 contracted into the second mounting bracket increases. In other words, when the second alignment portion 211 moves to the second position, the second alignment portion 211 can contract into the second connecting bracket 20. This is not only beneficial to reducing the acting force of the first connecting bracket 10 received by the second alignment portion 211, thereby reducing friction, but also beneficial to other structures of the second connecting bracket 20 sharing the acting force from the first connecting bracket 10 to avoid interfering with the relative sliding between the first connecting bracket 10 and the second connecting bracket 20, making the relative sliding between the two smoother and improving the user experience.

[0071] In some embodiments, the second alignment portion 211 is fixedly arranged on the second connecting bracket 20. Exemplarily, when the first connecting bracket 10 is connected to the second connecting bracket 20, the first connecting bracket 10 abuts against the second alignment portion 211. Since the second alignment portion 211 is fixedly arranged, a certain included angle is formed between the first connecting bracket 10 and the second connecting bracket 20, and the size of the included angle is determined by the height of the second alignment portion 211.

[0072] As the first connecting frame 10 and the second connecting frame 20 slide relative to each other, when the second alignment portion 211 is snapped onto the first alignment portion 111, the angle between the first connecting frame 10 and the second connecting frame 20 is 0°, and the first hole 121 in the first connecting frame 10 and the second hole 221 in the second connecting frame 20 are aligned with each other.

[0073] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 shown, the first alignment portion 111 may be a hole, and the second connecting frame 20 is provided with a receiving space 212 for receiving the second alignment portion 211. The second alignment portion 211 includes a clamping member (not shown in the figure) and an elastic member (not shown in the figure). The clamping member is installed in the receiving space 212, and the elastic member is disposed between the clamping member and the second connecting frame 20. One end of the elastic member abuts against the second connecting frame 20, and the other end abuts against the clamping member. It should be noted that when the first connecting frame 10 is not connected to the second connecting frame 20, the elastic member is in its free length.

[0074] When the first connecting frame 10 is connected to the second connecting frame 20, the first connecting frame 10 presses and holds the clamping member, and the clamping member contracts into the receiving space 212 and compresses the elastic member. At this time, the clamping member is in the second position.

[0075] As the first connecting frame 10 and the second connecting frame 20 slide relative to each other, when the first connecting frame 10 and the second connecting frame 20 slide to the target position (specifically, the position where the axis of the first alignment portion 111 coincides with the axis of the clamping member), the clamping member extends out of the receiving space 212 under the elastic force of the elastic member and extends into the first alignment portion 111 to restrict the relative position of the first connecting frame 10 and the second connecting frame 20. At this time, the clamping member is in the second position. Preferably, the second alignment portion 211 is a spring pin, which is not only convenient for users to replace but also inexpensive.

[0076] In some embodiments, the second alignment portion 211 can also be manually moved to the first position or the second position. Exemplarily, the first alignment portion 111 is a hole, and the second connecting frame 20 is provided with a receiving space 212 for receiving the second alignment portion 211. The second alignment portion 211 includes a clamping member that is slidably installed in the receiving space 212. A pushing member (not shown in the figure) is provided at one end of the clamping member away from the first connecting frame 10, and the user drives the clamping member to move to the first position or the second position through the pushing member.

[0077] In other embodiments, the second alignment portion 211 and the first alignment portion 111 are arranged in reverse, that is, the first alignment portion 111 can be moved to the first position or the second position, and the second alignment portion 211 is a hole. The present application does not make a limitation in this regard, and those skilled in the art can choose according to the actual situation.

[0078] In some embodiments, such as Figure 1 and Figure 6 shown, the wall-mounted device 100 further includes a rolling member 30, and the rolling member 30 is disposed between the first connecting frame 10 and the second connecting frame 20 and is in rolling connection with the first connecting frame 10 and the second connecting frame 20.

[0079] Understandably, since the rolling member 30 is disposed between the first connecting frame 10 and the second connecting frame 20, when the first connecting frame 10 is connected to the second connecting frame 20, the rolling member 30 rotates and abuts against the first connecting member 23, and a rolling gap is formed between the first connecting frame 10 and the second connecting frame 20. When the first connecting frame 10 and the second connecting frame 20 slide relative to each other, the rolling member 30 will roll under the action of the first connecting frame 10 or the second connecting frame 20.

[0080] By providing the rolling member 30, the surface contact between the first connecting frame 10 and the second connecting frame 20 can be transformed into point contact between the rolling member 30 and the first connecting frame 10, and the sliding friction between the first connecting frame 10 and the second connecting frame 20 can be transformed into rolling friction.

[0081] Compared with sliding friction, the friction of rolling friction is smaller, which can not only make it easier for the user to push the external device 200, but also make the relative sliding between the first connecting frame 10 and the second connecting frame 20 smoother.

[0082] In other embodiments, the first connecting frame 10 and the second connecting frame 20 may also adopt other sliding forms such as slide rails and sliders to achieve relative sliding. The present application does not limit this, and those skilled in the art can select according to the actual situation.

[0083] In some embodiments, such as Figure 6 , Figure 7 and Figure 8 shown, the wall-mounted device 100 further includes a limiting seat 40, and the limiting seat 40 is installed on the second connecting frame 20 and forms a rolling space (not shown in the figure) with the second connecting frame 20, and the rolling member 30 is installed in the rolling space.

[0084] The limiting seat 40 or the second connecting frame 20 is provided with a communication port 213, and the communication port 213 communicates with the rolling space and leads to the first connecting frame 10. A part of the rolling member 30 is exposed to the outside of the rolling space through the communication port 213 to rotate and abut against the first connecting frame 10. The limiting seat 40 is configured to prevent the rolling member 30 from disengaging from the rolling space.

[0085] Understandably, due to the friction between the first connecting frame 10 and the rolling member 30, when the first connecting frame 10 slides relative to the second connecting frame 20, the first connecting frame 10 drives the rolling member 30 to roll in the rolling space. However, during the rolling of the rolling member 30, the rolling member 30 tends to move along the sliding direction of the first connecting frame 10 relative to the second connecting frame 20.

[0086] At this time, the limit seat 40 abuts against the rolling member 30 to prevent the rolling member 30 from leaving the rolling space, which is beneficial to ensure that the rolling member 30 always rolls in the rolling space and reduces the risk of the rolling member 30 shifting during the rolling process, causing the first connecting frame 10 and the second connecting frame 20 to derail, thereby improving the safety and stability of the wall-mounted device 100.

[0087] In some embodiments, Figure 6 and Figure 7 As shown, the first connecting frame 10 has a rolling surface 112, and the second connecting frame 20 has a mounting surface 214. The rolling surface 112 and the mounting surface 214 are arranged opposite to each other, and the rolling element 30 is rotatably abutted against the rolling surface 112. Along the direction from the mounting surface 214 toward the rolling surface 112, when the second alignment portion 211 is in the first position, the height of the second alignment portion 211 protruding from the mounting surface 214 is greater than the height of the rolling element 30 protruding from the mounting surface 214.

[0088] It can be understood that by setting the height of the second alignment portion 211 protruding from the mounting surface 214 to be greater than the height of the rolling member 30 protruding from the mounting surface 214, it is helpful to improve the stability of the second alignment portion 211 being engaged with the first alignment portion 111 when in the first position, thereby ensuring the engagement of the second alignment portion 211 with the first alignment portion 111, and achieving the alignment of the first hole 121 in the first connecting frame 10 and the second hole 221 in the second connecting frame 20.

[0089] In other words, if the protruding height of the second alignment portion 211 is smaller than the protruding height of the rolling element 30, the second alignment portion 211 cannot be engaged with the first alignment portion 111, and cannot constrain the first connecting frame 10 and the second connecting frame 20, and cannot ensure the precise alignment of the first hole 121 and the second hole 221.

[0090] In some embodiments, Figure 6 and Figure 8 As shown, the stopper 40 is located on the side away from the mounting surface 214, and the second connecting frame 20 is provided with the above-mentioned connecting port 213. The rolling element 30 and the stopper 40 are arranged inside the second connecting frame 2020, which helps to protect the rolling element 30 and reduce the pollution of the rolling element 30 by external dust and particles, thereby extending the service life of the wall-mounted device 100.

[0091] Further, the limiting seat 40 is provided with a positioning port 41 which communicates with the rolling space, and the rolling member 30 is partially exposed to the outside of the rolling space through the positioning port 41. When assembling the rolling member 30 and the limiting seat 40, the positioning port 41 can position and limit the rolling member 30, so as to reduce the risk of slip misalignment of the rolling member 30 and the limiting seat 40 during the assembly process, facilitate the user to align and cooperate the rolling member 30 with the positioning port 41, and install the limiting seat 40 on the second connecting frame 20, thereby improving the assembly efficiency of the wall-mounted device 100.

[0092] In some embodiments, the limiting seat 40 is located on one side of the mounting surface 214 of the second connecting frame 20, and the limiting seat 40 is provided with a communication port 213. Arranging the rolling member 30 and the limiting seat 40 on the top of the second connecting frame 20 is beneficial for the user to inspect and repair the rolling member 30.

[0093] Further, the second connecting frame 20 is provided with a positioning port 41 which communicates with the rolling space, and the rolling member 30 is partially exposed to the outside of the rolling space through the positioning port 41. When assembling the rolling member 30 and the limiting seat 40, the positioning port 41 can position and limit the rolling member 30, so as to reduce the risk of slip misalignment of the rolling member 30 and the limiting seat 40 during the assembly process, facilitate the user to align and cooperate the rolling member 30 with the positioning port 41, and install the limiting seat 40 on the second connecting frame 20, thereby improving the assembly efficiency of the wall-mounted device 100.

[0094] In other embodiments, the rolling member 30 can also be installed on the first connecting frame 10 through the limiting seat 40. The present application does not make any limitation in this regard, and those skilled in the art can choose according to the actual situation.

[0095] In some embodiments, it is defined that an included angle is formed between the third direction and each of the first direction and the second direction. The first direction is the direction parallel to X shown in the figure, the second direction is the direction parallel to Y shown in the figure, and the third direction is the direction parallel to Z shown in the figure. For the convenience of referring to the figure, hereinafter the first direction is represented by "first direction X", the second direction is represented by "second direction Y", and the third direction is represented by "third direction Z". Optionally, in some embodiments, the first direction X, the second direction Y and the third direction Z are perpendicular to each other pairwise.

[0096] In some embodiments, such as Figure 1 and Figure 2 shown, the first connecting frame 10 includes a first mounting member 11 and a second mounting member 12. The first mounting member 11 and the second mounting member 12 are configured to be installed on the external device 200 at intervals along the second direction Y. The first mounting member 11 is provided with the above-mentioned first alignment portion 111, and the second mounting member 12 is provided with the above-mentioned first hole 121. The side surface of the first mounting member 11 facing the second mounting member 12 is a rolling surface 112.

[0097] The second connecting frame 20 includes a third mounting member 21 and a fourth mounting member 22. The third mounting member 21 and the fourth mounting member 22 are configured to be spaced apart along the second direction Y and mounted on the target 300. The second alignment portion 211 is provided on the third mounting member 21, and the second hole 221 is provided on the fourth mounting member 22. One side surface of the third mounting member 21 facing away from the fourth mounting member 22 is a mounting surface 214.

[0098] Exemplarily, when hanging the external device 200, the user first mounts the first mounting member 11 and the second mounting member 12 on the external device 200, and fixes the third mounting member 21 and the fourth mounting member 22 on the target 300. Subsequently, the user overlaps the first mounting member 11 on the third mounting member 21 and aligns the second mounting member 12 and the fourth mounting member 22. After the second mounting member 12 and the fourth mounting member 22 are aligned, the user pushes the external device 200, and the first mounting member 11 and the third mounting member 21 slide relative to each other, and the second mounting member 12 and the fourth mounting member 22 slide relative to each other.

[0099] When the first alignment portion 111 and the second alignment portion 211 are engaged and matched, the axis of the first hole 121 coincides with the axis of the second hole 221, that is, the alignment of the external device 200 and the target 300 is completed. At this time, the user only needs to connect the first hole 121 and the second hole 221 through a fixing member to fix the first connecting frame 10 and the second connecting frame 20, and then the hanging installation of the external device 200 can be completed.

[0100] By distributing the engagement position of the first alignment portion 111 and the second alignment portion 211 and the connection position of the first hole 121 and the second hole 221 in the second direction Y, it is beneficial to improve the connection stability of the first connecting frame 10 and the second connecting frame 20 in the second direction Y.

[0101] In some embodiments, both the first connecting frame 10 and the second connecting frame 20 adopt a split structure. When the wall-mounted device 100 is not in use, the user can disassemble the first mounting member 11 and the second mounting member 12 in the first connecting frame 10, and disassemble the third mounting member 21 and the fourth mounting member 22 in the second connecting frame 20, thereby reducing the occupied space of the wall-mounted device 100, which is beneficial for storage and transportation.

[0102] At the same time, since the first alignment portion 111, the first hole 121, the second alignment portion 211, and the second hole 221 are all provided on different components, if it is found that one or more of the first alignment portion 111, the first hole 121, the second alignment portion 211, and the second hole 221 are deformed or damaged, the user only needs to replace the corresponding component, and there is no need to replace the first connecting frame 10 or the second connecting frame 20 as a whole, saving the maintenance cost.

[0103] In some embodiments, such asFigure 1 , Figure 2 and Figure 7 As shown in Figure 1 , Figure 2 and Figure 7 , the second connecting frame 20 further includes a connecting member 23, and the connecting member 23 is arranged along the second direction Y. The two ends of the connecting member 23 are respectively connected to the third mounting member 21 and the fourth mounting member 22, and the third mounting member 21, the fourth mounting member 22 and the second connecting member 23 are in an "I" shape, that is, the second connecting frame 20 as a whole is in an "I" shape. The "I"-shaped second connecting frame 20 can bear a greater weight, enabling the wall-mounted device 100 to be applicable to external devices 200 of a greater weight, thereby improving the flexibility of the wall-mounted device 100.

[0104] In other embodiments, the first mounting member 11 and the second mounting member 12 in the first connecting frame 10 are of an integrally formed structure, and the third mounting member 21 and the fourth mounting member 22 in the second connecting frame 20 are of an integrally formed structure, which helps to simplify the manufacturing process of the wall-mounted device 100 and eliminates the need for multiple component manufacturing.

[0105] In some embodiments, as Figure 4 , Figure 5 and Figure 6 shown, when the second connecting frame 20 is installed on the target object 300, an assembly space 50 is formed between the third mounting member 21 and the target object 300 along the third direction Z. The wall-mounted device 100 further includes a guiding member 60, and the guiding member 60 is connected to the first mounting member 11. The guiding member 60 is configured to be inserted into the assembly space 50 along the second direction Y when the first connecting frame 10 is assembled to the target object 300.

[0106] Understandably, when connecting the first connecting frame 10 and the second connecting frame 20, the user only needs to insert the first mounting member 11 into the assembly space 50 through the guidance of the guiding member 60, and the connection between the first connecting frame 10 and the second connecting frame 20 can be achieved. The operation is simple and the assembly efficiency is high.

[0107] In some embodiments, as Figure 6 shown, the guiding member 60 is inclined with respect to the third direction Z. The guiding member 60 is configured to guide the first connecting frame 10 to approach the target object 300 from the second connecting frame 20 when the guiding member 60 is inserted into the assembly space 50 along the second direction Y.

[0108] Thereby, not only can the insertion angle between the first connecting frame 10 and the second connecting frame 20 be increased, making it easier for the first mounting member 11 to be inserted into the assembly space 50, but also through the cooperation of the inclined surface, the first connecting frame 10 can be guided to approach the target object 300 from the second connecting frame 20, reducing the alignment difficulty in the third direction Z.

[0109] In some embodiments, as Figure 1 , Figure 4 and Figure 7As shown, the first connecting frame 10 is provided with a first locking portion 122, and the second connecting frame 20 is provided with a second locking portion 222. When the first alignment portion 111 is engaged with the second alignment portion 211, the first locking portion 122 and the second locking portion 222 are aligned and configured to be connected to each other to fix the first connecting frame 10 and the second connecting frame 20.

[0110] By providing the first locking portion 122 and the second locking portion 222, secondary fixing can be performed on the basis of the hole connection to improve the fixing stability and safety of the connection between the first connecting frame 10 and the second connecting frame 20, and also help prevent others from casually disassembling the external device 200.

[0111] In some embodiments, the first connecting frame 10 is provided with a first anti-theft lock hole, and the second connecting frame 20 is provided with a second anti-theft lock hole. When the first alignment portion 111 is engaged with the second alignment portion 211, the axes of the first anti-theft lock hole and the second anti-theft lock hole are perpendicular to each other. At this time, the anti-theft lock is sequentially passed through the first anti-theft lock hole and the second anti-theft lock hole to fix the first connecting frame 10 and the second connecting frame 20.

[0112] In other embodiments, the first locking portion 122 and the second locking portion 222 can also be other suitable structures, and the present application does not limit this.

[0113] In some embodiments, the first connecting frame 10 is provided with a guiding groove 113 along the first direction X, and the second connecting frame 20 is configured to slide relative to the first connecting frame 10 along the guiding groove 113. By providing the guiding groove 113, it can play a guiding role in the relative sliding of the first connecting frame 10 and the second connecting frame 20, reducing the risk that the first hole 121 and the second hole 221 cannot be accurately aligned due to the deviation of the relative sliding of the first connecting frame 10 and the second connecting frame 20, which is beneficial to ensuring the accurate alignment of the external device 200 and the target object 300.

[0114] In some embodiments, as Figure 1 and Figure 3 shown, the first connecting frame 10 is further provided with a stopper 13, and the stopper 13 is arranged at both ends of the guiding groove 113 along the first direction X. The distance between the two stoppers 13 is greater than the distance of the guiding groove 113.

[0115] The stopper 13 is configured to stop the second connecting frame 20 when the first connecting frame 10 and the second connecting frame 20 slide relative to each other, so as to restrict the range of relative movement of the first connecting frame 10 and the second connecting frame 20, reducing the risk that the first connecting frame 10 and the second connecting frame 20 are disengaged due to the excessive relative movement distance of the first connecting frame 10 and the second connecting frame 20, and further improving the stability and safety of the wall-mounted device 100.

[0116] An embodiment of the present application further provides an inverter device (not shown in the figure). The inverter device includes a main unit (not shown in the figure) and the wall-mounted device 100 as described above, and the main unit is connected to the wall-mounted device 100. The main unit is used to implement the AC-DC conversion control of the output current of the battery pack. By adopting the wall-mounted device 100 as described above, the inverter device not only makes the installation operation more labor-saving, but also can improve the suspension installation efficiency of the inverter device.

[0117] Exemplarily, in the wall-mounted device 100, since the first connecting frame 10 and the second connecting frame 20 can slide relative to each other, the user can easily push the external device 200 when hanging the external device 200 for alignment installation operation. At the same time, during the relative sliding process of the first connecting frame 10 and the second connecting frame 20, the wall-mounted device 100 can achieve the rapid alignment of the first hole 121 in the first connecting frame 10 and the second hole 221 in the second connecting frame 20 through the snap-fit of the first alignment portion 111 and the second alignment portion 211, so as to facilitate the connection between the first hole 121 and the second hole 221, thereby fixing the first connecting frame 10 and the second connecting frame 20.

[0118] Working principle of the inverter device and the wall-mounted device 100: When hanging the inverter device, the user first connects the first connecting frame 10 to the inverter device and fixes the second connecting frame 20 to the target object 300. Subsequently, the first connecting frame 10 connected to the inverter device is connected to the second connecting frame 20, and the inverter device is pushed to make the first connecting frame 10 slide relative to the second connecting frame 20.

[0119] When the first alignment portion 111 and the second alignment portion 211 are snap-fitted, the first alignment portion 111 and the second alignment portion 211 jointly restrict the relative positions of the first connecting frame 10 and the second connecting frame 20. At this time, the first hole 121 in the first connecting frame 10 and the second hole 221 in the second connecting frame 20 are aligned with each other. The user connects the first hole 121 and the second hole 221 through a fixing member to fix the first connecting frame 10 and the second connecting frame 20, and the suspension installation of the inverter device can be completed.

[0120] In addition, those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as within the scope of the substantial spirit of the present application, appropriate changes and variations made to the above embodiments fall within the scope of the disclosure of the present application.
