[0002] After the air conditioner is packed in the box, it will be subjected to certain pressure and trampled during installation and transportation, and the side of the panel with a longer span of the air conditioner will be broken. Especially at the air inlet of the air conditioner, in order to ensure air circulation, inhale indoor air and guide it into the air conditioning system to promote air circulation and improve the freshness and cleanliness of indoor air, the air inlet of the air conditioner is generally a hollow structure, and the air inlet is generally located at the top of the air conditioner, located at the edge of the entire shell, which is more prone to pressure fracture. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art described above, the utility model provides a middle frame support reinforcement structure, which can solve the problem of pressure fracture at the air inlet of the air conditioner during installation and transportation.

[0004] The technical solution adopted by the utility model to solve the problem is:

[0005] A middle frame support reinforcement structure is arranged at the air inlet of the middle frame of an air conditioner, and is characterized in that it includes a reinforcement plate. The middle frame has a panel located on the front side thereof, and the reinforcement plate is arranged on the side of the panel facing the air inlet and is connected to the panel to support the panel to bear the load from the panel. The cross-section of the reinforcement plate is L-shaped, and one end is connected to the panel. The reinforcement plate and the panel form a first structural groove, and reinforcement ribs are provided in the first structural groove.

[0006] By adopting the above solution, a reinforcing plate is provided at the air inlet of the middle frame to improve the compressive strength of the panel, thereby reducing the problem of compression fracture at the air inlet of the air conditioner. In addition, the side walls of the first structural groove are connected by reinforcing ribs to further improve the ability to cope with the pressure acting on the panel of the middle frame of the air conditioner.

[0007] Furthermore, the reinforcing plate is provided with N spacing segments, and the spacing segments divide the reinforcing plate into N+1 segments.

[0008] By adopting the above solution, the spacing sections are provided to divide the reinforcing plate into multiple sections, thereby shortening the length of the reinforcing plate and reducing the possibility of the reinforcing plate being broken by stress.

[0009] Furthermore, the interval segment is provided with a reinforcement structure for enhancing the bending strength of the interval segment.

[0010] By adopting the above solution, a reinforcement structure is provided to ensure the strength of the interval section and prevent the panel from breaking at the interval section. The reinforcement structure adopts a plate arranged in a fishbone shape to improve the compressive strength of the interval section.

[0011] Furthermore, the notch of the first structural groove is arranged to face away from the air inlet direction of the air inlet, and the reinforcing plate is provided with a material transfer angle rib on a side facing away from the first structural groove, and the material transfer angle rib connects the panel and the reinforcing plate.

[0012] By adopting the above solution, the notch of the first structural groove is arranged to face away from the air inlet direction of the air inlet, which facilitates the design of the mold and saves production costs. In addition, the height difference between the panel and the first structural groove is large. The provision of the material transfer angle ribs facilitates material transfer during production on the one hand, but increases the risk of breakage at the cantilever caused by the height difference on the other hand.

[0013] Furthermore, the middle frame has a structural plate located at the back side of the middle frame, the structural plate is arranged opposite to the panel, and a support member perpendicular to the panel and the structural plate is provided between the panel and the structural plate.

[0014] By adopting the above solution, the support member is used to evenly distribute the load transmitted from the panel and the reinforcing plate, and plays a strong supporting role, thereby reducing the phenomenon of fracture at the air inlet of the middle frame.

[0015] Furthermore, the support member is provided with a second structural groove along its length direction, and a tie bar is provided in the second structural groove, and two ends of the tie bar are respectively connected to the groove walls on both sides of the second structural groove.

[0016] By adopting the above solution, since the support member needs to support the panel and the support plate, it is necessary to increase the cross-sectional area of ​​the support member to improve the bearing capacity of the support member. However, when the size of the support plate is too large, the support member will be subjected to uneven heating and uneven pressure in the processing mold, which will make it difficult to ensure the quality and stability of the support member. Therefore, a second structural groove is provided to reduce the size of the support member, thereby improving the production quality and stability of the support member. At the same time, tie bars are provided to ensure that the support member still has the corresponding compressive strength.

[0017] Furthermore, a diagonal brace plate is provided at the connection between the support member and the panel.

[0018] By adopting the above solution, the strength of the support member in the direction perpendicular to the air inlet is improved, and the support member is prevented from bending toward the inside of the air inlet and losing the supporting effect.

[0019] Furthermore, a tie plate is provided in the air inlet, and the tie plate is vertically connected to the support member.

[0020] By adopting the above solution, a tie plate is provided between the air inlet and the two sides parallel to the support member, and the tie plate ties the two sides of the support member together to improve the bending strength of the support member.

[0021] Furthermore, the tie plate is provided with a large footing structure at the connection between the tie plate and the support member.

[0022] By adopting the above scheme, the tie plate is provided with a large foot structure at the connection with the support member, so as to increase the contact area between the tie plate and the support member. Since the support member mainly bears the pressure from the surface layer, and the connection of the tie plate connected thereto will be subjected to corresponding shear force, a large foot structure is provided at the connection of the tie plate in the vertical direction thereof to cope with the shear force at the connection between the support member and the tie plate when the support member is under pressure, so as to prevent the connection between the support member and the tie plate from breaking during the force process.

[0023] Furthermore, the support member and the tie plate are each provided in plurality, and are vertically staggered and arranged in a mesh shape at the air inlet.

[0024] By adopting the above solution, smooth airflow at the air inlet is ensured, while the problem of insufficient structural strength caused by the large-span through holes at the entire air inlet is improved. More importantly, the strength of the middle frame to cope with the load from the panel is improved, reducing the fracture phenomenon at the panel due to pressure during storage and transportation.

[0025] In summary, the middle frame support reinforcement structure provided by the utility model has the following technical effects:

[0026] A reinforcement plate is provided at the air inlet of the middle frame to improve the compressive strength of the panel, thereby reducing the problem of compression fracture at the air inlet of the air conditioner. In addition, the side walls of the first structural groove are connected by reinforcing ribs to further improve the ability to cope with the pressure acting on the panel of the middle frame of the air conditioner.

[0034] In order to facilitate the understanding of the embodiments of the present utility model, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0035] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] The utility model discloses a middle frame support reinforcement structure, referring to Figure 1 and Figure 2As shown, it is arranged at the air inlet 130 of the air conditioner middle frame 100, including a reinforcing plate 200. The middle frame 100 has a panel 110 and a structural plate 120 arranged opposite to the panel 110. The reinforcing plate 200 is arranged on the side of the panel 110 facing the air inlet 130, and is connected to the panel 110 to support the panel 110 to bear the load from the panel 110. The cross-section of the reinforcing plate 200 is L-shaped, and one end is connected to the panel 110. The reinforcing plate 200 and the panel 110 form a first structural groove 210, and a reinforcing rib 220 is provided in the first structural groove 210.

[0038] Specifically, the reinforcing plate 200 is arranged on the side of the panel 110 close to the air inlet 130, and the compressive strength of the panel 110 is increased, thereby reducing the problem of compression fracture at the air inlet 130 of the air conditioner. The reinforcing plate 200 can be integrally formed with the panel 110 to ensure the stability of the load of the panel 110 during transmission. By setting the first structural groove 210 to reduce the thickness of the reinforcing plate 200, it is ensured that the pressure and heat are uniform during production, thereby strengthening the production quality of the plate 200, and the side walls of the first structural groove 210 are connected by the reinforcing ribs 220, so as to further improve the ability to cope with the pressure acting on the panel 110 of the air conditioner middle frame 100.

[0039] In some embodiments, reference Figure 1 and Figure 2 As shown, in order to reduce the span length of the reinforcing plate 200, enhance the structural strength of the reinforcing plate 200, and further enhance the pressure bearing capacity of the plate surface 110, N interval sections 230 are provided in the middle of the reinforcing plate 200, and the interval sections 230 divide the reinforcing plate 200 into N+1 sections. Specifically, the manufacturer can set the number of interval sections 230 according to demand. In this embodiment, there are 4 interval sections 230, and they are arranged at equal intervals, so as to shorten the length of the reinforcing plate 200, thereby reducing the possibility of the reinforcing plate 200 being broken by force.

[0040] In addition, in order to ensure the bending strength of the spacer section 230, refer to Figure 2 As shown, the interval section 230 is provided with a reinforcing structure 231 to enhance the bending strength at the interval section 230. Specifically, due to the high strength at the location where the reinforcing plate 200 is provided, the panel 110 at the interval section 230 is very easy to break, so it is necessary to provide a reinforcing structure 231 at the interval section 230 to ensure the strength of the interval section 230 and prevent the panel 110 from breaking at the interval section 230. In this embodiment, the reinforcing structure 231 adopts a plate arranged in a fishbone shape to improve the compressive strength of the interval section 230. In order to facilitate production, the reinforcing structure 231 and the panel 110 can be integrally formed, which not only improves the strength, but also reduces the installation steps and saves labor costs.

[0041] In some embodiments, in order to reduce the difficulty of designing the mold used to produce the middle frame 100, refer to Figure 1 and Figure 2 As shown, the notch of the first structural groove 210 is set to face away from the air inlet direction of the air inlet 130, and the side of the reinforcing plate 200 facing away from the first structural groove 210 is provided with a material corner rib 510 connecting the panel 110 and the reinforcing plate 200. The notch of the first structural groove 210 is set to face away from the air inlet direction of the air inlet 130, which is convenient for the design of the mold and saves production costs. Due to the setting of the L-shaped reinforcing plate 200, the reinforcing plate 200 is higher than the panel 110 connected thereto, and there is a risk of fracture. Therefore, the material corner rib 510 is set at the connection between the reinforcing plate 200 and the panel 110 to improve the bending strength of the reinforcing plate 200 at the overhanging part. More importantly, the panel 110 on the side facing the air inlet 130 is thickened at the edge to ensure its strength and the overall texture of the product. After the thickening treatment, a large step difference will be caused between the edge of the panel 110 and the center of the panel 110, which will cause excessive pressure during material feeding, resulting in problems with the quality of the molding being difficult to ensure. The provision of the material feeding angle ribs 510 can facilitate material feeding during production, reduce the impact of the high step difference, and ensure the quality of the middle frame 100. The number and position of the material feeding angle ribs 510 can be set according to actual production or strength requirements. In this embodiment, multiple material feeding angle ribs 510 are evenly set along the connection between the reinforcing plate 200 and the panel 110.

[0042] In some embodiments, in order to further improve the strength of the panel 110 to cope with pressure, refer to Figure 1 and Figure 2 As shown, a support member 300 perpendicular to the panel 110 and the structural plate 120 is provided between the panel 110 and the structural plate 120. One end of the support member 300 is vertically connected to the panel 110, and the other end is vertically connected to the structural plate 120. The load transmitted from the panel 110 and the reinforcing plate 200 can be well distributed, and a strong supporting effect is played, thereby reducing the phenomenon of fracture at the air inlet 130 of the middle frame 100.

[0043] In some embodiments, in order to improve the supporting effect of the support member 300, refer to Figure 1 and Figure 2As shown, the support member 300 is provided with a second structural groove 310 along the length direction, and a tie rib 320 is provided in the second structural groove 310 to connect the groove walls on both sides of the second structural groove 310. Specifically, the support member 300 needs to support the panel 110 and the support plate, so it is necessary to increase the cross-sectional area of ​​the support member 300 to improve the bearing capacity of the support member 300. However, when the size of the support plate is too large, the support member 300 will be heated and pressed unevenly in the processing mold, which will lead to the problem that the quality and stability of the support member 300 are difficult to ensure. Therefore, the second structural groove 310 is provided to reduce the size of the support member 300, ensure the uniformity of heating and pressure during the production process of the support member 300, thereby improving the production quality and stability of the support member 300, and at the same time, the tie rib 320 is provided to ensure that the support member 300 still has the corresponding compressive strength. The tie ribs 320 can be provided with corresponding numbers and tie angles as required. In this embodiment, the tie ribs 320 are vertically connected to the two side walls of the second structural groove 310 to achieve the best load-balancing effect when the panel 110 is under pressure. In addition, the second structural groove 310 can be provided with the notch of the second structural groove 310 facing the inside of the middle frame 100 or facing the outside of the middle frame 100 as required. The notch facing the inside of the middle frame 100 can prevent dust accumulation in the second structural groove 310, and the notch facing the outside of the middle frame 100 facilitates the design of the production mold of the middle frame 100 and facilitates production.

[0044] In some embodiments, in order to improve the bending resistance of the support member 300, refer to Figure 1 and Figure 5 As shown, a diagonal brace plate 500 is provided at the connection between the support member 300 and the panel 110. The diagonal brace plate 500 is arranged in the form of a corbel column to improve the strength of the support member 300 in a direction perpendicular to the air inlet 130 and prevent the support member 300 from bending inwardly of the air inlet 130 and losing the supporting effect. The designer can set the number and position of the diagonal brace plates 500 according to the requirements. In this embodiment, only one diagonal brace plate 500 is provided at the middle support member 300 with the worst bearing capacity to meet the design strength requirements.

[0045] In addition, the bending resistance of the support member 300 can also be improved by providing a tie plate 400 between the two sides parallel to the air inlet 130 and the support member 300, and the tie plate 400 is vertically connected to the support member 300. Through the above structure, the tie plate 400 is provided between the two sides parallel to the air inlet 130 and the support member 300, and the tie plate 400 ties the two sides of the support member 300 to improve the bending strength of the support member 300.

[0046] On the basis of the structure of the tie plate 400, refer to Figure 1 and Figure 2As shown, the tie plate 400 is provided with a large foot structure 410 at the connection with the support member 300, so as to increase the contact area between the tie plate 400 and the support member 300. Since the support member 300 mainly bears the pressure from the surface layer, and the connection of the tie plate 400 connected thereto will be subjected to the corresponding shear force, the large foot structure 410 is provided at the connection of the tie plate 400 in the vertical direction thereof, so as to cope with the shear force at the connection between the support member 300 and the tie plate 400 during the compression process of the support member 300, and prevent the connection between the support member 300 and the tie plate 400 from breaking during the stress process. In this embodiment, the large foot structure 410 adopts an inwardly concave arc surface for transition, which is convenient for production.

[0047] In addition, you can refer to Figure 1 As shown, multiple support members 300 and tie plates 400 are provided, and are vertically staggered and arranged in a mesh at the air inlet 130. At the same time, in order to facilitate production and the integrity of the middle frame 100, the support members 300 and the tie plates 400 are integrally formed. The support members 300 and the tie plates 400 are arranged in a mesh to ensure smooth airflow at the air inlet 130, while improving the problem of insufficient structural strength caused by the large-span through holes at the entire air inlet 130. More importantly, it improves the strength of the middle frame 100 to cope with the load from the panel 110, and reduces the fracture phenomenon at the panel 110 caused by pressure during storage and transportation.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
