Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a power board assembly for cooking appliances. Background Art

[0002] The power strip assembly of a cooking appliance typically consists of a power strip bracket and a power strip. These brackets are secured to the power strip using locking screws. However, the use of two or more screws can lead to wear and tear at the threaded connection due to excessive force or other factors, resulting in a loss of engagement and difficulty tightening the threaded connection. Furthermore, the screws can easily shift during production, causing the bracket and power strip to loosen. The threaded connection is also prone to failure after repeated disassembly.

[0003] Therefore, other methods of securing the power strip bracket and the power strip have emerged in the prior art besides screws, such as snap-on connections. These snap-on connections require a fixing clip to be provided on the power strip bracket, which is then pressed against the power strip to secure it. However, this method creates a high compressive force between the fixing clip and the power strip, which can easily damage components on the power strip and increases the risk of the fixing clip breaking, resulting in a low yield rate for the power strip assembly.

[0004] In addition, some power strip assemblies have both fixed clips and elastic clips on the power strip bracket. When assembling the power strip, the power strip is first tilted and one end is engaged with the fixed clip. Then, the other end of the tilted power strip is pressed down to engage the elastic clip. During assembly, the power strip is tilted and its edges are stressed, so it is subjected to a large bending force, which can not only cause the power strip to bend or even damage it, but also, when pressing down on the power strip, the end of the power strip that mates with the fixed clip exerts a large squeezing force on the fixed clip, which may damage the fixed clip. Utility Model Content

[0005] The utility model provides a power board assembly for cooking appliances to solve the problems of low assembly efficiency of the power board and the power board bracket, and easy damage to the power board and the fixing structure on the power board bracket during the assembly process, resulting in low product yield.

[0006] The technical solution adopted by this utility model is:

[0007] A power board assembly for a cooking appliance includes a power board and a mounting bracket, the mounting bracket having a mounting surface and a fixing clip protruding upward from the mounting surface, the fixing clip having a clamping portion at one end away from the mounting surface, and an installation space for installing the power board formed between the clamping portion and the mounting surface; a limiting member is protruding from the mounting surface, and a limiting hole is provided on the power board corresponding to the limiting member, and the limiting member can float up and down relative to the mounting surface to have a limited state of extending into the limiting hole, and an unlocked state of being released from the limiting hole.

[0008] The power board assembly for cooking appliances of the present invention also has the following additional technical features:

[0009] The mounting surface is further provided with a protruding support rib, and a mounting space is formed between the support rib and the clamping portion. The support rib and the clamping portion are arranged correspondingly up and down; or, the support rib and the clamping portion are arranged staggered up and down.

[0010] At least part of the supporting ribs forms a mounting position on the mounting surface, and the limiting member is arranged at the mounting position.

[0011] At least part of the fixing buckle and / or the supporting rib is elastically connected to the mounting bracket so that the fixing buckle and / or the supporting rib can float up and down relative to the mounting surface.

[0012] The limiting member includes a shell and an elastic part located between the shell and the mounting surface. The mounting surface is provided with a mounting position for installing the limiting member. The mounting position and / or the shell are provided with a guide rib, and the elastic part is sleeved on the outside of the guide rib.

[0013] The mounting bracket has retaining ribs surrounding the outer periphery of the mounting position, the retaining ribs forming a guide channel perpendicular to the mounting surface, and the shell is provided with guide rib positions, which cooperate with the inner wall of the guide channel.

[0014] The mounting surface is provided with a through hole in the mounting position, and the shell is provided with a limiting rib, which passes through the through hole to cooperate with the mounting bracket stopper to limit the shell from escaping from the mounting position.

[0015] The shell body is provided with an action section for extending into the limiting hole, and a guide transition surface is provided on the top surface of the action section.

[0016] The fixing clip and the limit member are arranged on both sides of the mounting surface relative to each other in the first direction to form a mounting channel extending along the second direction. A stop wall is provided at one end of the mounting channel. The first direction and the second direction are perpendicular, and both the first direction and the second direction are parallel to the mounting surface.

[0017] The mounting bracket has a side wall, and the fixing buckle is arranged on the side wall. The fixing buckle includes a limit buckle and an elastic buckle. The side wall is provided with a space-avoiding groove on both sides of the elastic buckle to enable the elastic buckle to be elastically deformed.

[0018] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0019] 1. In the present invention, a mounting space for the power board is formed between the engaging portion of the fixing clip and the mounting surface of the mounting bracket. The power board can be inserted laterally into the mounting space from one side of the mounting bracket. During installation, the power board is not subjected to squeezing or bending forces from the fixing clip. This significantly reduces the risk of damage to the power board or the fixing clip, making installation smoother, reducing assembly difficulty, and improving assembly efficiency and yield. After the power board is installed, the upper portion is restrained upward by the engaging portion, while the lower portion is supported downward by the mounting surface. Simultaneously, as the power board is pushed into the mounting space, the restraining member compresses and contracts, freeing the power board and allowing it to enter the mounting space smoothly. When the power board is fully installed, the restraining member releases its push and springs upward, extending into the retaining hole of the power board. It is then restrained by the inner wall of the retaining hole, restraining the power board laterally. This restraint locks the power board vertically and horizontally to the mounting bracket, effectively locking the power board and the mounting bracket. During the entire assembly process, the power board can maintain a horizontal posture and move laterally without excessive squeezing with the fixing clips, thereby improving the smoothness and efficiency of assembly.

[0020] 2. As a preferred embodiment of the present invention, the mounting surface further includes a protruding support rib, which forms a mounting space between the support rib and the clamping portion. The support rib protrudes from the mounting surface and cooperates with the clamping portion to clamp the power board. This not only stabilizes the power board, but also creates a gap between the power board and the mounting surface, thereby facilitating heat dissipation from the power board, preventing excessive temperature rise during operation, and extending the service life of the power board.

[0021] 3. As a preferred embodiment of the present invention, at least part of the fixing clips and / or support ribs are elastically connected to the mounting bracket so that the fixing clips and / or support ribs can float up and down relative to the mounting surface. At least part of the fixing clips and / or support ribs can float up and down, so that the power board can be clamped according to the thickness and position of the power board, so that the mounting bracket can adapt to power boards of more thickness sizes, thereby improving versatility. And while ensuring the clamping force on the power board, it can reduce the probability of the fixing clips and support ribs interfering with the power board during the installation process of the power board. In addition, when the power board assembly shakes, it can also be shock-absorbing through the elastically connected fixing clips or support ribs, reducing the vibration and shaking transmitted to the power board, so that the power board maintains a stable position and stable circuit connection.

[0022] 4. As a preferred embodiment of the present invention, the fixing clips and the limiting members are relatively arranged on both sides of the mounting surface in the first direction to form a mounting channel extending along the second direction, and a stop wall is provided at one end of the mounting channel. The first direction and the second direction are perpendicular, and the first direction and the second direction are parallel to the mounting surface. The fixing clips are located on both sides of the mounting surface to form a mounting channel, and the power board extends into the mounting channel along the second direction and moves into place along the mounting channel. One end of the mounting channel has an opening for the power board to enter and exit the mounting space, and the other end has a stop wall for prompting that the power board is installed in place. This makes the installation direction of the power board unique and can only be assembled and disassembled from one end of the opening of the mounting channel, thereby further reducing the difficulty of installing the power board and making it easier for the assembler to install the power board in the correct posture.

[0023] 5. As a preferred embodiment of the present invention, the mounting bracket has a side wall, and the fixing buckle is provided on the side wall. The fixing buckle includes a limit buckle and an elastic buckle. The side wall is provided with a space-avoiding groove on both sides of the elastic buckle so that the elastic buckle can be elastically deformed. The elastic buckle can move in the horizontal direction toward or away from the installation space. When the power board enters the installation space, the side of the power board forms an outward squeezing force on the elastic buckle, causing it to undergo elastic deformation, and then forms a clamping force on the power board toward the inside of the installation space under the action of its own elastic force, so as to limit the power board at the upper and outer sides of the power board at the same time, further improving the stability of the power board. At the same time, when the size of the power board increases due to processing errors, the elastic buckle can increase the area of ​​the installation space in the outer shape so that the power board can enter the installation space normally, thereby compensating for certain errors and improving the yield rate.

[0036] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0040] In the present invention, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "implementation method", "embodiment", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0041] like Figures 1 to 4 As shown, a power strip 1 assembly for a cooking appliance includes a power strip 1 and a mounting bracket 2. The mounting bracket 2 has a mounting surface 21 and a fixing clip 23 protruding upward from the mounting surface 21. The fixing clip 23 has a clamping portion 233 at one end away from the mounting surface 21. An installation space 24 for installing the power strip 1 is formed between the clamping portion 233 and the mounting surface 21. A limiting member 3 is protruded from the mounting surface 21, and a limiting hole 11 is provided on the power strip 1 corresponding to the limiting member 3. The limiting member 3 can float up and down relative to the mounting surface 21 to have a limited state of extending into the limiting hole 11, and an unlocked state of being detached from the limiting hole 11.

[0042] In the present invention, an installation space 24 for installing the power board 1 is formed between the clamping portion 233 of the fixing clip 23 and the mounting surface 21 of the mounting bracket 2. The power board 1 can enter the installation space 24 laterally from one side of the mounting bracket 2. During the installation process of the power board 1, it will not be subjected to the squeezing force and bending force from the fixing clip 23, thereby greatly reducing the risk of damage to the power board 1 or the fixing clip 23, and making the installation of the power board 1 smoother, reducing the difficulty of assembly, and improving assembly efficiency and yield rate. After the power board 1 is installed, the upper part is stopped by the clamping portion 233 to form an upward limit, and the lower part is supported by the mounting surface 21 to form a downward limit. At the same time, in the process of the power board 1 being pushed into the installation space 24, the limit member 3 is squeezed to cause the limit member 3 to shrink, forming a avoidance for the power board 1, so that the power board 1 can smoothly enter the installation space 24. When the power board 1 is fully installed, the retaining member 3 releases its push and springs upward, extending into the retaining hole 11 of the power board 1. It is then stopped by the inner wall of the retaining hole 11, restraining the power board 1 laterally. This restrains the power board 1 vertically and horizontally, locking it to the mounting bracket 2 and securing it to the mounting bracket 2. Throughout the assembly process, the power board 1 can remain horizontal and move laterally, preventing excessive compression against the retaining clips 23, improving assembly smoothness and efficiency.

[0043] It is understandable that if Figure 2 、 Figure 4 As shown, the limiting member 3 can float up and down relative to the mounting surface 21 to switch between a restricted state and an unlocked state. When the limiting member 3 is aligned with the limiting hole 11, the limiting member 3 extends into the limiting hole 11 and forms a stop with the inner wall of the limiting hole 11. During the installation of the power board 1, if the limiting member 3 is misaligned with the limiting hole 11, the limiting member 3 is pressed by the power board 1 and contracts, allowing the power board 1 to move within the installation space 24.

[0044] Specifically, such as Figure 6 As shown, the fixing buckle 23 and the limit member 3 are relatively arranged on both sides of the mounting surface 21 in the first direction to form a mounting channel extending along the second direction. A stop wall 211 is provided at one end of the mounting channel. The first direction and the second direction are perpendicular, and the first direction and the second direction are both parallel to the mounting surface 21.

[0045] Fixing clips 23 are located on either side of mounting surface 21 to form a mounting channel. The power board 1 extends into the mounting channel along the second direction and moves along the mounting channel into position. One end of the mounting channel has an opening 212 for the power board 1 to enter and exit mounting space 24, and the other end has a stop wall 211 to indicate that the power board 1 is properly installed. This ensures that the power board 1 can only be installed and removed from the mounting channel through opening 212, further simplifying the installation of the power board 1 and making it easier for the assembler to install the power board 1 in the correct position.

[0046] like Figure 1 、 Figure 6 As shown, the power board 1 is a square structure with two long sides and two short sides arranged opposite to each other. The shape of the mounting surface 21 is adapted to the shape of the power board 1. In one embodiment, as shown in FIG. Figure 6 As shown, the first direction is the length direction of the mounting surface 21, the second direction is the width direction of the mounting surface 21, the fixing buckles 23 are respectively provided at the two short sides of the mounting surface 21, and the mounting channel extends from one long side of the mounting surface 21 to the other long side. Figure 6 As shown, when installing the power board 1, extend the long side of the power board 1 from the opening 212 at one end of the installation channel into the installation space 24 in a direction parallel to the long side of the installation surface 21, and continuously push the power board 1 inward until the long side of the power board 1 forms a stop with the stop wall 211 at one end of the installation channel.

[0047] During this process, the sidewalls 22 on the two short sides of the mounting surface 21, or the fixing clips 23, guide the two short sides of the power board 1, ensuring that the power board 1 always moves in the second direction. Simultaneously, the stopper 3 can be manually pressed down, or pressed against the power board 1 to cause it to sink, thus avoiding the power board 1. When the stopper hole 11 moves to align with the stopper 3, the stopper 3 loses its pressure and extends into the stopper hole 11, forming a horizontal stop with the power board 1.

[0048] When disassembling the power board 1, first use a tool to press down the limit member 3 to make it disengage from the limit hole 11, and then pull the power board 1 horizontally in a direction opposite to the second direction to move it out from the opening 212 end of the installation channel.

[0049] During the entire installation process of the power board 1, only the force of horizontal movement inside the installation channel is applied to the power board 1. The limit member 3 can automatically complete the switching between the two states, and automatically cooperate with the limit hole 11 when the power board 1 moves into place to achieve self-locking. There is no need to use other additional components to lock the power board 1 and the installation bracket 2. While simplifying the assembly steps and improving assembly efficiency, it also simplifies the structure of the installation bracket 2 and saves costs.

[0050] Further, if Figure 1、 Figure 6 As shown, the mounting bracket 2 has a side wall 22, and a fixing buckle 23 is arranged on the side wall 22. The fixing buckle 23 includes a limiting buckle 231 and an elastic buckle 232. The side wall 22 is provided with a space-avoiding groove 221 on both sides of the elastic buckle 232 to enable the elastic buckle 232 to be elastically deformed.

[0051] The elastic buckle 232 can move horizontally toward or away from the installation space 24. When the power board 1 enters the installation space 24, the side of the power board 1 exerts an outward squeezing force on the elastic buckle 232, causing it to elastically deform. This, under the action of its own elastic force, clamps the power board 1 toward the interior of the installation space 24, thereby limiting the power board 1 from both the top and the outside, further improving the stability of the power board 1. Furthermore, if the size of the power board 1 increases due to manufacturing errors, the elastic buckle 232 can expand the area of ​​the installation space 24 by deforming the outer shape, allowing the power board 1 to enter the installation space 24 normally, thereby compensating for certain errors and improving the yield rate.

[0052] Specifically, the limit buckle 231 is set on the long side of the mounting surface 21, and the elastic buckle 232 is set on the short side of the mounting surface 21, that is, the limit buckle 231 is set on the stop wall 211 of the mounting channel, and the elastic buckle 232 is set on both sides of the mounting channel along the first direction.

[0053] The setting of the air avoidance groove 221 can improve the elastic deformation ability of the elastic buckle 232, making it easier to deform and increasing the deformation amount. On the basis of ensuring the clamping force on the power board 1, it effectively reduces the extrusion force between the two and reduces the risk of the fixing buckle 23 being broken and damaged due to excessive force.

[0054] As a preferred embodiment of the present invention, Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the mounting surface 21 is further provided with a protruding support rib 25 , and a mounting space 24 is formed between the support rib 25 and the clamping portion 233 .

[0055] The supporting ribs 25 protrude from the mounting surface 21 and cooperate with the clamping portion 233 to clamp the power board 1. On the one hand, this makes the fixation of the power board 1 more stable. On the other hand, it also creates a gap 12 between the power board 1 and the mounting surface 21, thereby facilitating the heat dissipation of the power board 1, avoiding excessive temperature rise of the power board 1 during operation, and increasing the service life of the power board 1.

[0056] This embodiment does not limit the relative positional relationship between the support ribs 25 and the clamping portion 233. In one embodiment, the support ribs 25 and the clamping portion 233 are positioned vertically in a corresponding manner. This arrangement allows the support ribs 25 and the clamping portion 233 to more closely clamp the power board 1, thereby improving the stability of the clamping. In another embodiment, the support ribs 25 and the clamping portion 233 are offset vertically to disperse the forces exerted on the power board 1, preventing excessive localized forces on the power board 1, which could cause bending or deformation.

[0057] Of course, multiple fixing buckles 23 and supporting ribs 25 can also be provided, wherein some supporting ribs 25 are provided correspondingly to the clamping portion 233 up and down, and some supporting ribs 25 are provided staggered with the clamping portion 233 up and down.

[0058] Preferably, if Figure 6 As shown, at least a portion of the support ribs 25 forms a mounting position 251 on the mounting surface 21 , and the limiting member 3 is disposed at the mounting position 251 .

[0059] At least a portion of the support ribs 25 forms a mounting position 251 for mounting the position-limiting member 3. This allows the support ribs 25 to not only support the power board 1 but also to mount the position-limiting member 3, limiting its movement and guiding its movement. This multi-functional component simplifies the structure of the mounting bracket 2, reduces costs, and more centrally positions the position-limiting member 3 and the support ribs 25, improving the stability of the position-limiting member 1 and reducing any wobble of the power board 1.

[0060] Specifically, such as Figure 5 As shown, the support ribs 25 form a guide channel 253 perpendicular to the mounting surface 21 , and the limiting member 3 is installed in the guide channel 253 so that the limiting member 3 can float in a direction perpendicular to the mounting surface 21 .

[0061] In a preferred embodiment, at least a portion of the fixing buckle 23 and / or the supporting rib 25 is elastically connected to the mounting bracket 2 so that the fixing buckle 23 and / or the supporting rib 25 can float up and down relative to the mounting surface 21 .

[0062] At least a portion of the fixing clips 23 and / or support ribs 25 can float up and down perpendicular to the mounting surface 21, thereby clamping the power board 1 according to its thickness and position. This allows the mounting bracket 2 to accommodate power boards 1 of various thicknesses, improving versatility. Furthermore, while ensuring the clamping force on the power board 1, the probability of the fixing clips 23 and support ribs 25 interfering with the power board 1 during installation is reduced. Furthermore, when the power board 1 assembly shakes, the elastically connected fixing clips 23 or support ribs 25 can provide shock absorption, reducing the vibration and shaking transmitted to the power board 1, thereby maintaining a stable position and circuit connection for the power board 1.

[0063] It is understandable that the elastic force exerted by the elastic member on the clamping portion 233 and the supporting rib 25 is directed toward the inside of the installation space 24, so that the two clamp the power board 1 under the action of the elastic force.

[0064] In a preferred embodiment, Figure 5 、 Figure 7 As shown, the limiting member 3 includes a shell 31 and an elastic portion 33 located between the shell 31 and the mounting surface 21. The mounting surface 21 is provided with a mounting position 251 for installing the limiting member 3. The mounting position 251 and / or the shell 31 are provided with a guide rib 252. The elastic portion 33 is sleeved on the outside of the guide rib 252.

[0065] The elastic portion 33 is sleeved on the outer side of the guide rib 252. The guide rib 252 can guide the elastic deformation of the elastic portion 33 so that it always deforms and moves in a direction perpendicular to the mounting surface 21, thereby improving the movement reliability of the limiter 3. Figure 5 As shown, the elastic portion 33 is a spring. In one embodiment, as shown in FIG. Figure 5 As shown, the guide rib 252 is provided at the mounting position 251, one end of the elastic portion 33 is sleeved outside the guide rib 252, and the housing 31 is provided with an annular rib 311. The other end of the elastic portion 33 is accommodated within the area enclosed by the annular rib 311, so that the annular rib 311 and the guide rib 252 jointly limit the elastic portion 33. Of course, the guide rib 252 can also be provided on the housing 31, and this is not limited here.

[0066] Further, if Figure 5 、 Figure 6 As shown, the mounting bracket 2 has retaining ribs surrounding the outer periphery of the mounting position 251 , which form a guide channel 253 perpendicular to the mounting surface 21 . The shell 31 is provided with a guide rib position 32 , which cooperates with the inner wall of the guide channel 253 .

[0067] At least a portion of the housing 31 is accommodated within the guide channel 253, and the guide ribs 32 contact the inner wall of the guide channel 253, thereby guiding the movement of the housing 31 and limiting the movement of the housing 31 to a direction perpendicular to the mounting surface 21. Of course, in other embodiments, other methods can be used to guide the movement of the housing 31 within the guide channel 253. For example, a guide protrusion can be provided on one of the housing 31 and the inner wall of the guide channel 253, and a guide groove can be provided on the other, with the protrusion and groove cooperating to achieve movement guidance.

[0068] Specifically, such as Figure 6 As shown, the mounting surface 21 is provided with a plurality of support ribs 25, and some of the support ribs 25 constitute retaining ribs to enclose the mounting position 251. Figure 6As shown, the mounting position 251 is set at the angle between the long side and the short side of the mounting surface 21.

[0069] Further, if Figure 6 、 Figure 7 As shown, the mounting surface 21 is provided with a through hole in the mounting position 251 , and the shell 31 is provided with a limiting rib 34 , which passes through the through hole to cooperate with the mounting bracket 2 to stop the shell 31 from escaping from the mounting position 251 .

[0070] like Figure 7 As shown, a laterally extending hook 341 is provided at the lower end of the limiting rib 34, and the limiting rib 34 passes through the through hole. When the shell 31 moves upward to the limit position, the hook 341 at the lower end of the limiting rib 34 cooperates with the stopper of the mounting bracket 2, so that the shell 31 cannot continue to move upward.

[0071] Preferably, there are two guide ribs 32 and two limiting ribs 34 . The guide ribs 32 are relatively arranged on two sides of the shell 31 , and the limiting ribs 34 are relatively arranged on the other two sides of the shell 31 .

[0072] like Figure 7 As shown, the housing 31 has an action section for extending into the limiting hole 11 , and a guide transition surface 312 is provided on the top surface of the action section.

[0073] The provision of the guide transition surface 312 makes it easier for the housing 31 to be pushed forward by the power board 1 and move. The guide transition surface 312 can convert the horizontal thrust of the power board 1 into a force perpendicular to the mounting surface 21. When the assembler pushes the power board 1 horizontally, the power board 1 can press the housing 31 downward, causing it to sink. This eliminates the need for additional tools to press the stopper 3 when installing the power board 1, reducing the difficulty of assembly.

[0074] At the same time, when the shell 31 slightly interferes with the edge of the limiting hole 11 due to processing errors and assembly errors, the shell 31 can be normally popped out into the limiting hole 11 through the guiding transition surface 312, completing the locking of the power board 1 and improving the yield rate.

[0075] The guide transition surface 312 can be an inclined surface, an arc surface or an irregular curved surface, etc., which is not limited here. Figure 7 As shown, the guide transition surface 312 can be relatively arranged on the top of both sides of the shell 31, or can circumferentially surround the top of the shell 31, which is not limited here.

[0076] Anything not described in this utility model can be achieved by adopting or drawing on existing technologies.

[0077] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0078] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of the claims of the present invention.
