Description

Technical Field

[0001] The utility model relates to the technical field of infant products, in particular to a dining tray assembly and a child seat. Background Art

[0002] In order to improve the functionality of child seats and facilitate children's dining, a dining tray is usually provided on the seat. In order to improve the comfort of children during dining, the dining tray usually protrudes from the seat in the horizontal direction. Therefore, when the child seat is squeezed or impacted during use, the dining tray is squeezed or impacted before the seat. The cracks caused by squeezing or impacting the dining tray in the prior art are likely to affect the aesthetics of the seat and even affect the safety of the child. Utility Model Content

[0003] The main purpose of the utility model is to provide a dining tray assembly and a child seat, aiming to solve the technical problem of how to reduce the degree of deformation of the dining tray assembly after being impacted, improve the aesthetics of the child seat and at the same time improve the safety of the child seat.

[0004] To achieve the above-mentioned purpose, the utility model provides a dinner plate assembly, comprising:

[0005] A first cover plate, comprising a first plate body and a first flange connected to an outer periphery of the first plate body; and

[0006] A second cover plate, comprising a second plate body, a second flange and a second rib, wherein one end of the second flange is connected to the outer periphery of the second plate body, and the other end is connected to the outer periphery of the first flange, the second cover plate and the first cover plate together define an inner cavity, the second rib is disposed in the inner cavity and connects the second plate body and the second flange, the second rib comprises an abutment portion located on a side away from the second plate body, the abutment portion extends out of the second flange in a direction away from the second plate body and is spaced apart from the first flange;

[0007] Among them, the first cover plate also includes a first rib, the first rib is located in the inner cavity and connected to the first plate body, the first rib includes a first end connected to the first flange, and the first end is provided with a first recessed portion facing the first plate body on the side away from the first plate body.

[0008] In the present application, the arrangement of the first rib is conducive to improving the structural strength of the meal tray assembly to reduce the deformation degree of the meal tray assembly, and reduce the probability of the meal tray assembly being broken by impact or extrusion, thereby avoiding the situation that the user is scratched or scratched by the broken part of the meal tray assembly, thereby improving the safety of the meal tray assembly. The arrangement of the first recess can weaken the structural strength of the first rib, thereby reducing the difference between the deformation degree of the area where the first rib is not arranged on the first cover plate and the deformation degree of the area where the first rib is arranged on the first cover plate, reducing the stress concentration in the local area at the junction of the first flange and the first rib, thereby avoiding the formation of micro cracks on the surface of the first flange and affecting the aesthetics of the meal tray assembly. The abutment portion of the second rib extends into the inner side of the first flange, and the abutment portion is conducive to preventing the first cover plate from collapsing when it is subjected to a pressure perpendicular to the first plate body. In addition, since one side of the abutment portion is connected to the second flange, when the first flange is subjected to a severe impact and deforms in the direction of the inner cavity, the inner wall of the first flange squeezes the abutment portion and drives the second flange to deform together, thereby avoiding the formation of a gap at the joint of the first flange and the second flange, resulting in the child being pinched. In addition, the abutting portion can also play a certain structural reinforcement role on the first flange, thereby preventing the first flange from being hit or squeezed to produce white lines.

[0009] In some embodiments, one side of the first recess extends to the side wall of the first flange facing the inner cavity;

[0010] or,

[0011] The first recessed portion is spaced apart from a side wall of the first flange facing the inner cavity.

[0012] In some embodiments, the first rib further includes a second end portion, the second end portion is located on a side of the first end portion away from the first flange, and a second recessed portion recessed toward the first plate body is provided on a side of the second end portion away from the first plate body.

[0013] The provision of the second recess can further weaken the structural strength of the first rib, thereby preventing the plate assembly from producing white lines due to a large difference in deformation between the impact point and the surrounding area when the plate assembly is impacted or squeezed, thereby affecting the aesthetics.

[0014] In some embodiments, the first recessed portion extends from a side of the first flange away from the first flange to a side of the first rib away from the first flange.

[0015] When the first flange is impacted or squeezed, the stress of the first rib away from the first flange gradually decreases, so the first recess in this embodiment can reduce the weight of the first cover plate while ensuring the dispersion of the stress of the first flange. In addition, the first recess in this embodiment is also beneficial to the demoulding process during the manufacturing process of the first cover plate.

[0016] In some embodiments, a bending portion is formed at the first end portion, so that an angle formed by the first end portion and the first flange is smaller than an angle formed by an extension line of the second end portion and the first flange.

[0017] In this embodiment, the first rib is provided with a first recessed portion and a bent portion. The bent portion can convert the impact force or extrusion force acting on the first flange into a bending deformation of the first rib. At the same time, the first recessed portion can convert the impact force or extrusion force into a contraction deformation of the first rib, thereby reducing the deformation amount of the first flange impact point and effectively reducing the probability of white lines on the first flange.

[0018] In some embodiments, the first flange includes a straight section and a curved section, and the first end portion is connected to the straight section.

[0019] The first recess is disposed at the first end portion, and thus, the first recess is disposed on the first rib connected to the straight section, thereby preventing the straight section of the first flange from generating white lines that affect the appearance when impacted or squeezed.

[0020] In some embodiments, the abutting portion has an abutting wall facing the first flange, and the abutting wall gradually moves away from the first flange in a direction away from the second plate body.

[0021] The abutting portion having the abutting wall is also helpful in simplifying the positioning difficulty during the assembly process of the first cover plate and the stacking cover plate.

[0022] The second aspect of the utility model also provides another dinner plate assembly, comprising:

[0023] A first cover plate, comprising a first plate body and a first flange connected to an outer periphery of the first plate body; and

[0024] A second cover plate, comprising a second plate body, a second flange and a second rib, wherein one end of the second flange is connected to the outer periphery of the second plate body, and the other end is connected to the outer periphery of the first flange, the second cover plate and the first cover plate together define an inner cavity, the second rib is disposed in the inner cavity and connects the second plate body and the second flange, the second rib comprises an abutment portion located on a side away from the second plate body, the abutment portion extends out of the second flange in a direction away from the second plate body and is spaced apart from the first flange;

[0025] The first cover plate further includes a first rib, the first rib is located in the inner cavity and connected to the first plate body, one end of the first rib extends to connect to the first flange, and one end of the first rib connected to the first flange includes a bent portion.

[0026] The bending portion can convert the bending deformation perpendicular to the first flange wall into tension, compression and bending deformation within the first rib plane, thereby reducing the deformation near the impact point of the first flange, and further reducing the stress concentration phenomenon at the impact point on the first flange, effectively reducing the probability of white lines.

[0027] In some embodiments, one end of the curved portion is connected to the first flange, the first plate body has a first wall facing the inner cavity, and the curved portion is bent and extended in a direction perpendicular to an axis of the first wall;

[0028] The first flange has a second wall surface facing the curved portion, and the curved portion has a first curved surface and a second curved surface arranged opposite to each other in a direction parallel to the first wall surface; at the junction of the first curved surface and the second wall surface, the angle between the first curved surface and the second wall surface is less than 90°; and / or, at the junction of the second curved surface and the second wall surface, the angle between the second curved surface and the second wall surface is greater than 90°;

[0029] The first cover plate includes a plurality of first ribs, and the bending directions of the bent portions of the first ribs are the same.

[0030] The same bending direction of the curved portions of each first rib is conducive to reducing the manufacturing difficulty of the first cover plate. Taking the preparation of the first cover plate by injection molding as an example, the same bending direction of the curved portions of the first ribs is conducive to the demoulding process of the first cover plate.

[0031] The third aspect of the utility model also provides a child seat, comprising:

[0032] The dinner plate assembly according to any one of the above embodiments;

[0033] A seat assembly, wherein the dining tray assembly is connected to the seat assembly, wherein the first cover plate is an upper dining tray cover plate, the second cover plate is a lower dining tray cover plate, and the dining tray assembly is connected to the seat assembly via the lower dining tray cover plate.

[0034] The child seat having the dining tray assembly described in the above embodiment has higher aesthetics and safety.

[0035] Compared with the prior art, the beneficial effects of the utility model are:

[0036] In the technical solution of the utility model, the dining tray assembly includes a first cover plate and a second cover plate, the first cover plate includes a first plate body and a first flange connected to the outer periphery of the first plate body, and the outer periphery of the second cover plate is connected to the first flange, so as to define an inner cavity together with the first cover plate. The setting of the second cover plate can improve the structural strength of the dining tray assembly while improving the aesthetics of the dining tray assembly, and the setting of the second cover plate makes the bottom of the dining tray assembly smoother and flatter, thereby effectively avoiding the situation that children are scratched or abraded due to shaking of their hands and feet during the meal. Among them, the first cover plate also includes a first rib, which is located in the inner cavity and connected to the first plate body. The first rib includes a first end connected to the first flange, and a first concave portion concavely arranged toward the first plate body is provided on the side of the first end away from the first plate body. When the dining tray assembly is squeezed or impacted, the first rib can improve the structural strength of the dining tray assembly to reduce the deformation degree of the dining tray assembly, reduce the probability of the dining tray assembly being broken by impact or squeezing, thereby avoiding the situation that the user is scratched or scratched by the broken part of the dining tray assembly, thereby improving the safety of the dining tray assembly. In addition, when the dining tray assembly is hit or squeezed, the setting of the first recess or the curved portion can weaken the structural strength of the first rib, thereby reducing the difference between the deformation degree of the area where the first rib is not set on the first cover plate and the deformation degree of the area where the first rib is set on the first cover plate, reducing the stress concentration in the local area at the junction of the first flange and the first rib, thereby avoiding the formation of micro cracks on the surface of the first flange and affecting the aesthetics of the dining tray assembly. The abutment portion of the second rib extends into the inner side of the first flange, and the abutment portion is conducive to preventing the first cover plate from collapsing when it is subjected to pressure perpendicular to the first plate body, so as to compensate for the reduction of structural strength due to the first recess or the curved portion. In addition, since one side of the abutment portion is connected to the second flange, when the first flange is severely hit and deformed in the direction of the inner cavity, the inner wall of the first flange squeezes the abutment portion and drives the second flange to deform together, thereby avoiding the appearance of a gap at the joint of the first flange and the second flange, resulting in the child being pinched. In addition, the abutment portion can also play a certain structural reinforcement role on the first flange, avoiding the first flange from being hit or squeezed to produce white lines.

[0062] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0063] For this reason, please see Figures 2 to 7In a first aspect, the utility model provides a dining tray assembly 100, which includes a first cover plate 110 and a second cover plate 120. In some embodiments, the first cover plate 110 can provide a dining platform for children, that is, the first cover plate 110 is located above the second cover plate 120, and the second cover plate 120 is arranged below the first cover plate 110. In other embodiments, the second cover plate 120 can be used to provide a dining platform for children, that is, the second cover plate 120 is located above the first cover plate 110, and the first cover plate 110 is arranged below the second cover plate 120. For ease of description, the following description is based on an example in which the first cover plate 110 is arranged above the second cover plate 120. The first cover plate 110 includes a first plate body 111 and a first flange 112 connected to the outer periphery of the first plate body 111. The first plate body 111 and the first flange 112 can be prepared by an integral molding method, and the first flange 112 and the first plate body 111 have a smooth transition. The first plate body 111 can provide a dining platform for children. The provision of the first flange 112 can improve the structural strength of the first plate body 111 and reduce the mass of the first cover plate 110, thereby improving the lightweight design of the dining tray assembly 100. The outer periphery of the second cover plate 120 is connected to the first flange 112, thereby defining an inner cavity 130 together with the first cover plate 110. In some embodiments, the peripheral side of the second cover plate 120 is connected to the side of the first flange 112 facing the inner cavity 130. In other embodiments, the side of the first flange 112 facing away from the first plate 111 abuts against the side of the second cover plate 120 facing the inner cavity 130, and the peripheral side of the second cover plate 120 is flush with the side of the first flange 112 facing away from the inner cavity 130. A connecting column can be provided on the side of the first cover plate 110 or the second cover plate 120 facing the inner cavity 130, and the connecting column is provided with a threaded hole, so that the first cover plate 110 and the second cover plate 120 can be connected by a threaded fastener (for example, a screw). The provision of the second cover plate 120 can improve the structural strength of the dining tray assembly 100 while improving the aesthetics of the dining tray assembly 100. In addition, since the dining tray assembly 100 can be assembled on the child seat 10 through other structural parts, there will inevitably be some angular protruding structures at the bottom of the dining tray assembly 100. The provision of the second cover plate 120 makes the bottom of the dining tray assembly 100 smoother and flatter, thereby effectively preventing children from being scratched or abraded due to shaking of their hands and feet during meals.

[0064] Among them, see Figure 4 and Figure 5, the first cover plate 110 further includes a first rib 113, which is located in the inner cavity 130 and connected to the first plate body 111. The first rib 113 includes a first end connected to the first flange 112. When the dining tray assembly 100 is squeezed or impacted, the first rib 113 can improve the structural strength of the dining tray assembly 100 to reduce the deformation of the dining tray assembly 100, reduce the probability of the dining tray assembly 100 being broken by the impact or squeezing, thereby avoiding the user from being scratched or scratched by the broken part of the dining tray assembly 100, thereby improving the safety of the dining tray assembly 100. It should be noted that the first cover plate 110 includes a plurality of first ribs 113, each of which is orderly distributed on the first plate body 111, thereby improving the structural strength of the first plate body 111 while reducing the weight of the first cover plate 110, and at least part of the first plate body 111 is connected to the first flange 112. A first recess 1131 recessed toward the first plate body 111 is provided on the side of the first end away from the first plate body 111. When the dining tray assembly 100 is impacted or squeezed, the provision of the first recess 1131 can weaken the structural strength of the first rib 113, thereby reducing the difference in deformation between the area of ​​the first cover plate 110 where the first rib 113 is not provided and the area of ​​the first cover plate 110 where the first rib 113 is provided. Compared with the related art, in the present application, when the dining tray assembly 100 is squeezed or impacted, the first rib 113 can be deformed at the first recess 1131 under the squeezing force or the impact force, that is, the size of the first recess 1131 along the extension direction of the first rib 113 becomes smaller, thereby reducing the stress concentration in the local area at the junction of the first flange 112 and the first rib 113, thereby avoiding the formation of micro cracks on the surface of the first flange 112 at the junction with the first rib 113 to affect the aesthetics of the dining tray assembly 100.

[0065] It should be noted that the tiny cracks formed by the first flange 112 can change the way light is scattered in the crack area. Specifically, when light is irradiated onto the first flange 112, the light that should be smoothly reflected or refracted will be scattered when encountering the crack. Due to the presence of the crack, the propagation path of light in the crack area becomes complicated, resulting in a change in the refractive index of the light. This change in refractive index makes the light scattering method in the crack area different from that in the surrounding area, thus forming a significant visual contrast. This contrast makes the crack area appear more prominent visually, usually appearing white or light-colored. For ease of expression, such tiny cracks can be called white lines. Such white lines not only destroy the overall smoothness and texture of the dinner plate assembly 100, but also greatly reduce the aesthetics of the dinner plate assembly 100.

[0066] The direction perpendicular to the extension direction of the first rib 113 is defined as the first direction, and the plane perpendicular to the first direction is defined as the projection plane. The contour shape of the projection formed by the first concave portion 1131 on the projection plane may be an arc or a polygon. In some embodiments, the first concave portion 1131 penetrates the first rib 113 along the first direction. In some embodiments, one side of the first concave portion 1131 extends to the side wall of the first flange 112 facing the inner cavity 130. Taking the contour shape of the projection formed by the first concave portion 1131 on the projection plane as a semicircular arc as an example, the semicircular arc (it should be noted that arcs that are not full circles can be considered as semicircular arcs) formed by the first concave portion 1131 is projected close to the first flange 112, and the wall surface of the first flange 112 facing the inner cavity 130 is tangent or intersected. In other embodiments, the first recess 1131 is spaced apart from the side wall of the first flange 112 facing the inner cavity 130 , that is, there is a certain distance between the side of the first recess 1131 close to the first flange 112 and the side wall of the first flange 112 facing the inner cavity 130 .

[0067] The first rib 113 also includes a second end portion, the second end portion is located on a side of the first end portion away from the first flange 112, and a second recessed portion is provided on a side of the second end portion away from the first plate body 111, which is recessed toward the first plate body 111. That is, in some embodiments, the first rib 113 has a plurality of recessed portions along its extension direction, and for ease of description, the first rib 113 includes a first recessed portion 1131 provided at the first end portion and a second rib 123 provided at the second end portion, wherein the second rib 123 is located on a side of the first rib 113 away from the first flange 112, and the first recessed portion 1131 is spaced apart from the second recessed portion.

[0068] In some embodiments, the side of the first recess 1131 away from the first flange 112 extends to the side of the first rib 113 away from the first flange 112. In other embodiments, the first end portion connected to one end of the first flange 112 extends in a direction away from the first plate 111 to the side of the first flange 112 away from the first plate 111, that is, the side of the first end portion away from the first plate 111 is flush with the side of the first flange 112 away from the first plate 111. In yet other embodiments, the side of the first end portion away from the first plate 111 may also be slightly lower than the side of the first flange 112 away from the first plate 111, so as to facilitate the connection of the second cover plate 120 to the first cover plate 110.

[0069] See also Figure 2, the first flange 112 includes a straight section 1121 and a curved section 1122, and the first end is connected to the straight section 1121. Specifically, the first cover plate 110 is provided with a plurality of first ribs 113, each of which is connected to a side of the first plate body 111 close to the inner cavity 130, one end of some of the first ribs 113 is connected to the straight section 1121 of the first flange 112, and one end of some of the first ribs 113 is connected to the curved section 1122 of the first flange 112. When the dining plate assembly 100 is squeezed or impacted, the curved section 1122 of the first flange 112 is curved, so that, compared with the straight section 1121, the curved section 1122 can disperse the impact force or the squeezing force along the surface of the curved section 1122 through its curved structure, thereby reducing the concentration of the force on the single point of the curved section 1122, and further reducing the possibility of the curved section 1122 being deformed locally and causing white lines. Furthermore, when the curved section 1122 is impacted or squeezed, it can store elastic potential energy. When the impact force or squeezing force disappears, the stored elastic potential energy is released, so that the curved section 1122 can restore to an initial state to a certain extent (i.e., the state where the curved section 1122 is not impacted or squeezed), thereby reducing the possibility of permanent deformation of the curved section 1122. For the straight section 1121 of the first flange 112, the impact force or squeezing force will be concentrated at the impact point, thereby forming a local high stress area, while the stress in the area away from the impact point is lower. This uneven stress distribution will cause the straight section 1121 to be locally deformed or even damaged near the impact point. Therefore, in some embodiments, the first rib 113 connected to the first flange 112 may not be provided with the first recess 1131. In order to reduce the degree of deformation of the straight section 1121 after impact and weaken the degree of damage to the straight section 1121, a first recess 1131 is provided on the first rib 113 connected to the straight section 1121. The first rib 113 is used to enhance the anti-impact performance of the straight section 1121. At the same time, the first recess 1131 is used to provide a buffer for the local deformation of the straight section 1121, thereby reducing the probability of white lines and improving the aesthetics and service life of the dining plate assembly 100.

[0070] In some embodiments, see Figure 6 and Figure 7The second cover plate 120 includes a second plate body 121, a second flange 122 and a second rib 123. One end of the second flange 122 is connected to the periphery of the second plate body 121, and the other end is connected to the periphery of the first flange 112. It should be noted that in some embodiments, the second flange 122 and the second plate body 121 can be prepared by an integral molding method, and the second flange 122 can be sleeved on the periphery of the first flange 112. In another embodiment, the second flange 122 can also be sleeved on the inner side of the first flange 112. In another embodiment, the side of the first flange 112 away from the first plate body 111 abuts against the side of the second flange 122 away from the second plate body 121. The second rib 123 is provided in the inner cavity 130 and connects the second plate body 121 and the second flange 122. The provision of the second rib 123 is conducive to improving the structural strength of the second cover plate 120 and reducing the probability of the second cover plate 120 being damaged under the action of impact force or extrusion force. In some embodiments, the second ribs 123 are disposed at positions that correspond one-to-one with the first ribs 113. In other embodiments, the second ribs 123 are disposed at positions that are offset from the first ribs 113.

[0071] The second rib 123 includes an abutment portion 1231 located on a side away from the second plate body 121, and the abutment portion 1231 extends out of the second flange 122 in a direction away from the second plate body 121 and is spaced apart from the first flange 112. When the dining tray assembly 100 is impacted or squeezed, the first flange 112 is partially deformed toward the inner cavity 130 by the impact force or the squeezing force. When the first flange 112 is deformed toward the inner cavity 130 and contacts the abutment portion 1231, the abutment portion 1231 can decompose the impact force of part of the impact point of the first flange 112, thereby reducing the probability of the first flange 112 being broken due to excessive deformation caused by the impact force or the squeezing force. In addition, the setting of the abutment portion 1231 is also conducive to preventing the first cover plate 110 from collapsing due to the pressure perpendicular to the first plate body 111. It should be noted that after the first cover plate 110 and the second cover plate 120 are assembled, the minimum distance between the side of the abutment portion 1231 facing the first flange 112 and the side wall of the first flange 112 facing the inner cavity 130 is no more than 2 mm. Figure 6 and Figure 7 The second rib 123 may also be provided with a third recess 1232 , and the third recess 1232 may be provided on a side of the abutting portion 1231 away from the second flange 122 .

[0072] In some embodiments, the abutment portion 1231 has an abutment wall facing the first flange 112, and the abutment wall gradually moves away from the first flange 112 in a direction away from the second plate body 121. Specifically, after the first cover plate 110 and the second cover plate 120 are assembled, the distance between the side of the abutment portion 1231 facing the first flange 112 and the side wall of the first flange 112 facing the inner cavity 130 gradually increases in a direction from the second plate body 121 to the first plate body 111, that is, the abutment wall is inclined in a direction from the second plate body 121 to the first plate body 111 and in a direction away from the first flange 112. Therefore, when the first cover plate 110 and the second cover plate 120 are assembled, the abutment portion 1231 having the inclined abutment wall can improve the alignment efficiency of the first cover plate 110 and the second cover plate 120. In addition, when the second rib 123 and the second plate body 121 are prepared by an integral molding method (including but not limited to injection molding, hot pressing molding, etc.), the inclined abutment wall is conducive to improving the processing efficiency of the second cover plate 120. Exemplarily, when the second cover plate 120 is prepared by injection molding, the inclined abutment wall is conducive to the demoulding of the second cover plate 120, thereby improving the demoulding efficiency of the second cover plate 120, and can also reduce the probability of the second rib 123 being damaged during the demoulding process, thereby improving the yield rate of the second cover plate 120.

[0073] See also Figure 5In some embodiments, the first rib 113 is located in the inner cavity 130 and connected to the first plate body 111. One end of the first rib 113 extends to connect to the first flange 112. The first rib 113 includes a curved portion 1132, and the curved portion 1132 extends in a curved manner. For ease of description, a plane facing the first plate body 111 and perpendicular to the extension direction of the first flange 112 away from the first plate body 111 is defined as a projection plane. The contour shape of the projection formed by the curved portion 1132 on the projection plane can be in the form of multiple arcs, and the bending directions of adjacent arcs can be the same or different. The contour shape of the projection formed by the curved portion 1132 on the projection plane can also be in the form of a circular arc. For example, the "circular arc" can be a semicircular arc, a quarter circular arc, etc. The setting of the curved portion 1132 helps to disperse the impact force or extrusion force acting on the local first flange 112. Specifically, the curved portion 1132 can convert the bending deformation perpendicular to the wall surface of the first flange 112 into tension, compression and bending deformation in the plane of the first rib 113, thereby reducing the deformation near the impact point of the first flange 112, thereby reducing the stress concentration phenomenon at the impact point on the first flange 112, and effectively reducing the probability of white lines. In some embodiments, the first rib 113 can be provided with a first recess 1131 and a curved portion 1132 at the same time, and the first recess 1131 and the curved portion 1132 are arranged at intervals.
