[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0024] The following is for reference. Figures 1-15 Description of a base assembly 100 according to an embodiment of the present utility model.

[0025] refer to Figures 1-4According to a first aspect embodiment of the present invention, a base assembly 100 is used for a child safety seat 200 and includes a base body 10. The base body 10 includes an upper base cover 20 and a lower base cover 30. The base body 10 serves to support the child. The upper side of the upper base cover 20 is the side that contacts the child's buttocks, and the lower side of the lower base cover 30 is the side that contacts the car seat.

[0026] The base cover 20 includes a cover body 21 and an upper support rib 22, with the upper support rib 22 located on the underside of the cover body 21. For example, the number of upper support ribs 22 can be one or more.

[0027] The lower cover 30 is located below the upper cover 20 and includes a lower cover body 31 and a lower support rib 32. The lower support rib 32 is located above the lower cover body 31. The lower cover body 31 is connected to the upper cover body 21 and together defines a cavity 40. For example, the number of lower support ribs 32 can be one or more.

[0028] The upper support rib 22 and the lower support rib 32 are both located inside the cavity 40. The upper support rib 22 is located above the lower support rib 32, and at least a portion of the upper support rib 22 is arranged opposite to the lower support rib 32 in the vertical direction.

[0029] For example, at least a portion of the upper support rib 22 is arranged opposite to the lower support rib 32 in the vertical direction. This could be a portion of the upper support rib 22 being arranged opposite to the lower support rib 32 in the vertical direction, or all of the upper support ribs 22 being arranged opposite to the lower support rib 32 in the vertical direction. By placing both the upper support rib 22 and the lower support rib 32 within the cavity 40, the internal space of the cavity 40 can be utilized effectively, and the deformation resistance of the upper base cover 20 and the lower base cover 30 can be improved. When the base assembly 100 is subjected to downward pressure, the upper support rib 22 and the lower support rib 32 can disperse the stress on the surfaces of the upper base cover 20 and the lower base cover 30, thereby enhancing the structural strength of the upper base cover 20 and the lower base cover 30. Furthermore, by having at least a portion of the upper support rib 22 and the lower support rib 32 arranged opposite each other in the vertical direction, the upper support rib 22 and the lower support rib 32 can abut against each other. The mutual support between the upper support rib 22 and the lower support rib 32 can prevent the upper base cover 20 from continuing to sink downward, thereby reducing the degree of sinking deformation of the upper base cover 20 under stress and giving the base assembly 100 a longer service life.

[0030] According to the embodiment of the present utility model, the base assembly 100 has an upper support rib 22 on the lower side of the upper cover body 21 and a lower support rib 32 on the upper side of the lower base cover 30, which can improve the deformation resistance of the upper base cover 20 and the lower base cover 30 and enhance the structural strength of the base assembly 100. Furthermore, by arranging at least a portion of the upper support rib 22 and the lower support rib 32 opposite to each other in the vertical direction, so that the upper support rib 22 and the lower support rib 32 abut against each other, the degree of indentation deformation of the upper base cover 20 under force can be reduced, so that the base assembly 100 has a longer service life.

[0031] refer to Figure 5 In some embodiments, when the base assembly 100 is in an unoccupied state, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are spaced apart in the vertical direction to form a support gap 41, the height dimension of the support gap 41 in the vertical direction being 0.2mm to 0.8mm.

[0032] The unloaded state of the base assembly 100 refers to its state when it is not under load. For example, when the base assembly 100 is unloaded, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are spaced apart vertically; when the base assembly 100 is under load, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are in contact vertically. If the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are already in contact when the base assembly 100 is unloaded, then when the base assembly 100 is under load, the force between the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 will further increase, and the deformation of the upper support rib 22 and the lower support rib 32 will also further increase, making it easier to generate noise. When the base assembly 100 is in an unloaded state, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are spaced apart in the vertical direction to form a support gap 41. This can play a certain buffering role when the base assembly 100 is under load, reducing the noise caused by excessive deformation when the upper support rib 22 and the lower support rib 32 come into contact and are subjected to force. In addition, leaving a certain support gap 41 is conducive to the assembly of the upper cover 20 and the lower cover 30 of the base, reducing the interference between the upper support rib 22 and the lower support rib 32.

[0033] The height dimension of the support gap 41 in the vertical direction can be referenced. Figure 5The height h1 in the vertical direction of the support gap 41 can be 0.2mm, 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, etc. If the height h1 is too large, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 will not be able to abut when the base assembly 100 is under load, and it will not be able to support the base cover 20, making it difficult to reduce the degree of indentation deformation of the base cover 20 under stress; if the height h1 is too small, the buffering effect will not be obvious. By making the height of the support gap 41 in the vertical direction between 0.2mm and 0.8mm, it is possible to reduce the degree of indentation deformation of the base cover 20 under stress while providing a buffering effect, and reduce the noise generated when the upper support rib 22 and the lower support rib 32 abut and deform under mutual stress.

[0034] refer to Figures 6-8 In some embodiments, the upper support rib 22 includes a first upper support rib 221 and two second upper support ribs 222 extending in the vertical direction. The two second upper support ribs 222 are connected to opposite sides of the first upper support rib 221, and the first upper support rib 221 and the second upper support rib 222 are arranged at an angle. By making the upper support rib 22 include a first upper support rib 221 and two second upper support ribs 222 extending in the vertical direction, and by making the first upper support rib 221 and the second upper support rib 222 arranged at an angle, the structural strength of the upper support rib 22 can be increased, preventing damage under force when it abuts against the lower support rib 32. It also helps to increase the contact points between the upper support rib 22 and the lower support rib 32, thereby improving the stability when the upper support rib 22 abuts against the lower support rib 32.

[0035] refer to Figures 9-11 In some embodiments, the lower support rib 32 includes a first lower support rib 321 and a second lower support rib 322, both extending in the vertical direction. The first lower support rib 321 and the second lower support rib 322 are connected and arranged at an angle. By making the lower support rib 32 include a first lower support rib 321 and a second lower support rib 322, both extending in the vertical direction, and connecting the first lower support rib 321 and the second lower support rib 322 at an angle, the structural strength of the lower support rib 32 can be increased, preventing damage under stress when it abuts against the upper support rib 22. It also helps to increase the contact points between the upper support rib 22 and the lower support rib 32, thereby improving the stability of the lower support rib 32 when it abuts against the upper support rib 22.

[0036] refer to Figure 5In some embodiments, the base cover 20 includes a reinforcing rib 23 and a connecting rib 24. Both the reinforcing rib 23 and the connecting rib 24 are located on the lower side of the cover body 21. The connecting rib 24 is connected between the upper support rib 22 and the reinforcing rib 23. The height dimension of the connecting rib 24 in the vertical direction is smaller than the height dimension of the reinforcing rib 23 in the vertical direction and smaller than the height dimension of the upper support rib 22 in the vertical direction.

[0037] The height dimension of the upper support rib 22 in the vertical direction can be referenced. Figure 4 The height dimension of connecting rib 24 in the vertical direction (h2) can be referenced. Figure 4 The height dimension of reinforcing rib 23 in the vertical direction can be referenced in h3. Figure 4 h4 in the figure. The reinforcing rib 23 serves to increase the structural strength of the upper base cover 20. Furthermore, when the upper support rib 22 and the lower support rib 32 are in contact and deformed under stress, the connecting rib 24 connects the support rib and the reinforcing rib 23, which further improves the structural strength and deformation resistance of the upper support rib 22. By making the height dimension of the connecting rib 24 in the vertical direction smaller than that of the reinforcing rib 23 in the vertical direction and smaller than that of the upper support rib 22 in the vertical direction, the interference between the connecting rib 24 and the structure on the lower base cover 30 can be reduced, facilitating the assembly of the upper base cover 20 and the lower base cover 30.

[0038] refer to Figure 5 In some embodiments, the height dimension of the reinforcing rib 23 in the vertical direction is smaller than that of the upper support rib 22 in the vertical direction. By making the height dimension of the reinforcing rib 23 in the vertical direction smaller than that of the upper support rib 22 in the vertical direction, the structural strength of the reinforcing rib 23 can be improved, making the reinforcing rib 23 less prone to deformation. It can also reduce the interference between the reinforcing rib 23 and the structure on the lower cover 30 of the base, making it easier to assemble the upper cover 20 of the base and the lower cover 30 of the base.

[0039] refer to Figure 4 In some embodiments, there are multiple upper support ribs 22 and lower support ribs 32 that are spaced apart. The number of upper support ribs 22 is the same as the number of lower support ribs 32 and they correspond one-to-one. Each upper support rib 22 is located above the corresponding lower support rib 32, and at least a portion of the upper support rib 22 is arranged opposite to the corresponding lower support rib 32 in the vertical direction.

[0040] Wherein, at least a portion of the upper support rib 22 is arranged opposite to the corresponding lower support rib 32 in the vertical direction. This can be either a portion of the upper support rib 22 being arranged opposite to the corresponding lower support rib 32 in the vertical direction, or all of the upper support rib 22 being arranged opposite to the corresponding lower support rib 32 in the vertical direction.

[0041] By making the number of upper support ribs 22 the same as the number of lower support ribs 32 and corresponding one-to-one, the upper support ribs 22 of the base cover 20 and the lower support ribs 32 of the base cover 30 are positioned close to each other, which facilitates the assembly of the base cover 20 and the base cover 30. Furthermore, by making at least a portion of the upper support ribs 22 and the corresponding lower support ribs 32 opposite each other in the vertical direction, each upper support rib 22 can abut against the corresponding lower support rib 32 to provide a support point. The mutual support between the upper support ribs 22 and the lower support ribs 32 prevents the base cover 20 from sinking further downward, thereby reducing the degree of sinking deformation of the base cover 20 under stress and giving the base assembly 100 a longer service life.

[0042] refer to Figure 10 In some embodiments, multiple lower support ribs 32 are arranged at intervals along the circumference of the lower cover body 31. By arranging multiple lower support ribs 32 at intervals along the circumference of the lower cover body 31, the upper support ribs 22, which are the same number as the lower support ribs 32 and correspond one-to-one with each other, can also be arranged at intervals along the circumference of the upper cover body 21, thereby improving the structural strength of the base assembly 100. The contact between the circumferentially spaced upper support ribs 22 and the lower support ribs 32 can further reduce the degree of indentation deformation of the base cover 20 under stress, so that the base assembly 100 has a longer service life.

[0043] refer to Figure 10 In some embodiments, at least part of the lower support rib 32 is located at the rear of the lower cover body 31.

[0044] At least some of the lower support ribs 32 are located at the rear of the lower cover body 31. This can be either a portion of the lower support ribs 32 being located at the rear of the lower cover body 31, or all of the lower support ribs 32 being located at the rear of the lower cover body 31.

[0045] For example, there are two upper support ribs 22 and two lower support ribs 32. The two upper support ribs 22 are located at the rear of the upper cover body 21 and at the left and right ends of the upper cover body 21, respectively. When the base assembly 100 bears weight, the child's buttocks are positioned relatively rearward in the base assembly 100, and the child's legs are positioned relatively forward in the base assembly 100, resulting in greater pressure on the rear of the base assembly 100. By placing at least part of the lower support ribs 32 at the rear of the lower cover body 31, the structural strength of the rear of the lower cover body 31 can be strengthened. The mutual support between the upper support ribs 22 and the lower support ribs 32 prevents the rear of the base cover 20 from continuing to sink downward, thus facilitating the support of the base cover 20.

[0046] refer to Figures 6-11In some embodiments, the upper base cover 20 includes upper support positioning posts 25, which are located on the lower side of the upper cover body 21 and are arranged in multiple spaced intervals. The lower base cover 30 includes lower support positioning posts 33, which are located on the upper side of the lower cover body 31 and are arranged in multiple spaced intervals. The number of upper support positioning posts 25 is the same as the number of lower support positioning posts 33 and they correspond one-to-one. Each lower support positioning post 33 is provided with a positioning hole 331, and the lower end of the upper support positioning post 25 is inserted into the positioning hole 331. By inserting the lower end of the upper support positioning post 25 into the positioning hole 331 in the lower support positioning post 33, the stability of the connection between the upper base cover 20 and the lower base cover 30 can be improved, and the installation and disassembly of the upper base cover 20 and the lower base cover 30 can be facilitated. Furthermore, by having multiple upper support positioning posts 25 and lower support positioning posts 33 spaced apart, the stability of the connection between the upper base cover 20 and the lower base cover 30 can be further improved, preventing individual positioning posts from breaking under stress and causing the upper base cover 20 and the lower base cover 30 to separate, thereby improving the safety of the base assembly 100.

[0047] In some embodiments, the base cover 20 is a one-piece molded part. By making the base cover 20 a one-piece molded part, the number of parts can be reduced, and the installation process of installing structures such as the upper support rib 22 onto the base cover 20 can be eliminated, which is beneficial to improving production efficiency.

[0048] In some embodiments, the base cover 30 is a one-piece molded part. By making the base cover 30 a one-piece molded part, the number of parts can be reduced, and the installation process of installing structures such as the lower support rib 32 onto the base cover 30 can be eliminated, which is beneficial to improving production efficiency.

[0049] In some embodiments, the upper base cover 20 and the lower base cover 30 are detachably connected. By making the upper base cover 20 and the lower base cover 30 detachably connected, it is convenient to install and remove the upper base cover 20 and the lower base cover 30.

[0050] In some embodiments, the base assembly 100 further includes armrests 50, which are disposed on the upper side of the base cover 20 and located at both ends of the base cover 20. The armrests 50 and the base cover 20 can be detachably connected, for example, the armrests 50 and the base cover 20 can be snap-fitted together. By disposing of the armrests 50 on the upper side of the base cover 20 and located at both ends of the base cover 20, it is easier for children to place their hands or forearms on the armrests 50, thereby improving the comfort of the base assembly 100.

[0051] refer to Figures 1-2In some embodiments, the base assembly 100 further includes a storage cup 60, which is located at the front end of the base body 10. For example, there may be two storage cups 60, one of which may be located at the left front end of the base body 10, and the other at the right front end of the base body 10. By providing a storage cup 60 at the front end of the base body 10, miscellaneous items can be stored in the storage cup 60, making full use of the space in the cavity 40 of the base assembly 100.

[0052] refer to Figures 1-2 In some embodiments, the cup 60 is movable relative to the base body 10 between an extended position and a retracted position. In the extended position, the cup 60 extends outside the base body 10; in the retracted position, the cup 60 is located within the cavity 40. For example, when an item needs to be stored, the cup 60 is moved from the retracted position to the extended position, the item to be stored is placed in the cup 60, and then the cup 60 is moved from the extended position to the retracted position to complete the storage of the item. When an item needs to be removed, the cup 60 is moved from the retracted position to the extended position, the item is removed from the cup 60, and then the cup 60 is moved from the extended position to the retracted position. By allowing the cup 60 to move relative to the base body 10 between the extended position and the retracted position, the storage and retrieval of items are facilitated.

[0053] refer to Figure 9 In some embodiments, a guide post 34 is provided on the upper side of the lower cover body 31. The cup 60 includes a cup body 61 and a connecting arm 62. The connecting arm 62 is connected to the outer periphery of the cup body 61. A guide groove 621 extending along the length of the connecting arm 62 is provided on the connecting arm 62. The guide post 34 passes through the guide groove 621 in the vertical direction. When the cup 60 moves between the extended position and the retracted position, the guide post 34 can slide relative to the cup 60 along the guide groove 621. The guide post 34 guides the guide groove 621 and also limits the two ends of the guide groove 621. When the cup 60 moves from the retracted position to the extended position, both the cup body 61 and the connecting arm 62 move to the extended position, and the guide post 34 contacts the end of the guide groove 621 away from the cup body 61. When the cup 60 moves from the extended position to the retracted position, both the cup body 61 and the connecting arm 62 move to the retracted position, and the guide post 34 contacts the end of the guide groove 621 near the cup body 61. By providing a guide groove 621 extending along the length of the connecting arm 62 on the connecting arm 62, and having the guide post 34 pass through the guide groove 621 in the vertical direction, the movement trajectory of the cup 60 can be limited, allowing the cup 60 to move in a specific direction and stop at a suitable position, preventing the cup 60 from detaching from the base assembly 100 or from being difficult to remove from the cavity 40 of the base assembly 100.

[0054] refer to Figures 12-15 The safety seat 200 according to the second aspect of the present invention includes: a base assembly 100 and a backrest 70 according to the first aspect of the present invention, wherein the backrest 70 is connected to the rear end of the base assembly 100.

[0055] According to the present invention, the safety seat 200, by providing the aforementioned base assembly 100, has an upper support rib 22 on the lower side of the upper cover body 21 and a lower support rib 32 on the upper side of the lower base cover 30, which can improve the deformation resistance of the upper base cover 20 and the lower base cover 30 and enhance the structural strength of the base assembly 100. Furthermore, by arranging at least a portion of the upper support rib 22 and the lower support rib 32 opposite each other in the vertical direction, so that the upper support rib 22 abuts against the lower support rib 32, the degree of indentation deformation of the upper base cover 20 under force can be reduced, thus giving the safety seat 200 a longer service life.

[0056] refer to Figures 14-15 In some embodiments, the backrest 70 is rotatably connected to the base assembly 100, and the axis of rotation between the backrest 70 and the base assembly 100 extends in the left-right direction. For example, a connecting groove 11 is formed on the rear side of the upper cover body 21, and a connecting post 111 extending in the left-right direction is provided in the connecting groove 11.

[0058] In this embodiment, the base assembly 100 is used for the safety seat 200 and includes a base body 10. The base body 10 includes an upper base cover 20 and a lower base cover 30, both of which are integrally molded parts.

[0059] The base cover 20 includes a cover body 21, an upper support rib 22, a reinforcing rib 23 and a connecting rib 24, with the upper support rib 22 located on the lower side of the cover body 21.

[0060] The upper support rib 22 includes a first upper support rib 221 and two second upper support ribs 222 that both extend in the vertical direction. The two second upper support ribs 222 are connected to the opposite sides of the first upper support rib 221, and the first upper support rib 221 and the second upper support rib 222 are arranged at an angle.

[0061] Both the reinforcing rib 23 and the connecting rib 24 are located on the lower side of the upper cover body 21. The connecting rib 24 is connected between the upper support rib 22 and the reinforcing rib 23. The height dimension of the connecting rib 24 in the vertical direction is smaller than the height dimension of the reinforcing rib 23 in the vertical direction and smaller than the height dimension of the upper support rib 22 in the vertical direction. The height dimension of the reinforcing rib 23 in the vertical direction is smaller than the height dimension of the upper support rib 22 in the vertical direction.

[0062] The lower base cover 30 is located below the upper base cover 20 and includes a lower cover body 31 and a lower support rib 32. The lower support rib 32 is located above the lower cover body 31. The lower cover body 31 is connected to the upper cover body 21 and together defines a cavity 40. Both the upper support rib 22 and the lower support rib 32 are located within the cavity 40. The upper support rib 22 is located above the lower support rib 32. The number of upper support ribs 22 and the number of lower support ribs 32 are the same and correspond one-to-one. The upper support ribs 22 and the lower support ribs 32 are arranged opposite each other in the vertical direction. The upper support rib 22 is located at the rear of the upper cover body 21, and the lower support rib 32 is located at the rear of the lower cover body 31.

[0063] The lower support rib 32 includes a first lower support rib plate 321 and a second lower support rib plate 322 that both extend in the vertical direction. The first lower support rib plate 321 and the second lower support rib plate 322 are connected and set at an included angle.

[0064] When the base assembly 100 is in an unoccupied state, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are spaced apart in the vertical direction to form a support gap 41, the height dimension of the support gap 41 in the vertical direction is 0.5mm.

[0065] The upper base cover 20 includes upper support positioning posts 25, which are located on the lower side of the upper cover body 21 and are arranged at intervals. The lower base cover 30 includes lower support positioning posts 33, which are located on the upper side of the lower cover body 31 and are arranged at intervals. The number of upper support positioning posts 25 is the same as the number of lower support positioning posts 33 and they correspond one-to-one. Each lower support positioning post 33 has a positioning hole 331, and the lower end of the upper support positioning post 25 is inserted into the positioning hole 331.

[0066] When the base assembly 100 is in an unoccupied state, the bottom surface of the upper support rib 22 and the top surface of the lower support rib 32 are separated in the vertical direction, forming a support gap 41 in the middle, and the height dimension of the support gap 41 in the vertical direction is 0.5mm.

[0067] When the base assembly 100 bears the load, the base cover 20 deforms downward under the force, and the upper support rib 22 and the lower support rib 32 abut against each other in the vertical direction to prevent the base cover 20 from continuing to deform, so as to play a supporting role.
