Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0040] It should be noted that if the embodiments of the utility model involve directional indications, the directional indications are only used to explain the relative position relationship, movement condition and the like between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.
[0041] In addition, if the embodiments of the utility model involve descriptions such as "first", "second" and the like, the descriptions of "first", "second" and the like are only for description purposes, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features.

[0042] For the riding appliance such as a stroller, a jogger, a tractor and the like, considering the protection, a surrounding space is generally formed for children to ride, and the state of the children in the riding appliance can be lying or sitting, the surrounding plays a protective and shielding function, but also causes shielding.
[0043] For the children in the riding appliance, the surrounding shields the children's vision, limits the children's vision range and affects the observation of the external environment; for the accompanying personnel, if the riding appliance is fully shielded, the accompanying personnel cannot observe the state of the children in the riding appliance, and if the riding appliance is semi-shielded, since the accompanying personnel and the riding appliance are staggered in orientation, there is also a visual dead angle, and the state of the children cannot be observed, which may cause a safety hazard that the mouth and nose of the children are shielded.
[0044] Based on this, in order to solve the shielding problem of the surrounding of the riding tool, the utility model provides a carrier which is suitable for the riding tool with bearing function, for example, it can be fixed child seat, dining chair and the like, and also can be movable stroller, running car, trailer, tractor and the like.
[0045] In order to better understand the embodiments of the present application, the carrier provided by the embodiments of the present application will be described in detail below with reference to the drawings.
[0046] Please refer to Figures 1 to 2 The carrier 100 comprises a bearing seat 1, a frame 3 and a shielding part 2, the frame 3 is arranged on the bearing seat 1 and forms a bearing space with the bearing seat 1, and the shielding part 2 is arranged on the frame 3, and the light transmittance of the shielding part 2 is adjustable.
[0047] In the technical scheme of the utility model, the bearing space is used for children to ride, the shielding part 2 can be arranged on the side or the top of the bearing space, and plays a shielding role, and by adjusting the light transmittance of the shielding part 2, the shielding part 2 can have a light shielding state and a light transmitting state, so as to adapt to different use requirements. When in the light shielding state, the functions of preventing peeping and shielding can be realized, and when in the light transmitting state, the accompanying person can conveniently observe the condition of the children in the bearing space, and the children can also conveniently observe the external environment.
[0048] The bearing seat 1 can be arranged in the form of a support or a bottom plate, and the specific size, material and shape thereof are not limited, and the bearing seat 1 can only have a supporting function.
[0049] The shielding part 2 is arranged in a structure capable of realizing light transmittance adjustment, and the way of realizing light transmittance adjustment is not limited, in some embodiments, the transparency of the shielding part 2 can be adjusted, so that the shielding part can realize state changes such as full light shielding, half light shielding and full transparency. In some embodiments, the color of the shielding part 2 can be adjusted, that is, the shielding part can be arranged to change various colors, and different colors correspond to different light penetration effects, so that the change of the visible state can be realized. For example, in the case of the same material, the light shielding effect of black is better than that of other colors. In some embodiments, the transparency and color of the shielding part can be adjusted, not only the color change can be realized, but also different transparency changes can be obtained on the basis of different colors, so that the arrangement of the shielding part can be more flexible and changeable, not only having a better appearance effect, but also different colors can bring different visual experiences to children.
[0050] The utility model discloses to the installation position of shielding portion 2 is not limited, in some embodiments, frame 3 includes multiple side frame body 3a and the frame body opening surrounded by side frame body, shielding portion 2 is set up in side frame body 3a and completely covers frame body opening or shielding portion 2 covers partial frame body opening. The position of frame body opening is not limited, and multiple side frame body 3a corresponds to the different side of carrying space, and is connected with the carrying seat 1 cooperation, for example, multiple side frame body 3a is respectively located at the opposite two sides of carrying space, and again for example, multiple side frame body 3a is respectively located at the adjacent three sides of carrying space, and again for example, multiple side frame body 3a respectively corresponds the circumferential side of carrying space.
[0051] In one case, shielding portion 2 can be a whole set of components, and the light transmittance adjustment is a whole adjustment. Shielding portion 2 can also be a set of components that are spliced. According to the number of spliced modules, each module can be adjusted in light transmittance individually. In another case, shielding portion 2 can be provided in multiple, corresponding to multiple frame body openings. The light transmittance of the shielding portion 2 corresponding to the multiple frame body openings can be adjusted synchronously or individually, that is, according to the design needs, part of the shielding portion 2 can be transparent, and part of the shielding portion 2 cannot be transparent.
[0052] Based on the above embodiments, shielding portion 2 covers partial frame body opening, and frame 3 further has frame connecting piece connected between side frame body 3a and shielding portion 2. The connection mode of shielding portion 2 and side frame body 3a is not limited, and can be reasonably set according to the specific structure form of shielding portion 2 and the structure form of side frame body 3a. In an embodiment, the frame connecting piece is a cloth cover b fixedly connected to the side frame body 3a. The cloth cover b is fixedly connected to the frame. At this time, the shielding portion 2 can be installed on the corresponding side frame body 3a through the cloth cover b. In another embodiment, the shielding portion 2 is directly connected and fixed to the side frame body 3a and completely covers the frame body opening. At this time, the shielding portion 2 is directly connected to the side frame body 3a, for example, the shielding portion 2 can be installed on the side frame body 3a in the form of embedding, and only a corresponding embedding groove needs to be provided on the side frame body 3a.
[0053] For example, frame 3 further has a transparent baffle provided on side frame body 3a. The transparent baffle completely covers the frame body opening or covers partial frame body opening. The shielding portion 2 is fixed to the transparent baffle. At this time, the shielding portion 2 can be fixed by pasting. A clamping groove is provided on the transparent baffle for inserting and fixing the shielding portion 2. It should be understood that the transparent baffle can be glass or plastic, and the utility model does not limit this.
[0054] It should be noted that the plurality of side frames 3a can further include a top cover 4 located above the carrying space, and the top cover 4 is provided with a shielding part 2. It should be understood that the top cover 4 should correspond to the upper part of the child, and the top cover 4 can be provided as a fixed structure, that is, always kept above the carrying space in a covering manner, or the top cover 4 can be provided as a structure that can be turned over or folded, that is, the top cover 4 has a state of being above the carrying space and a position of avoiding the carrying space, and a turning mechanism can be provided to enable the top cover 4 to be transferred to the side of the carrying space, or a folding structure can be provided to enable the top cover 4 to be folded and stored on one side above the carrying space.
[0055] In one case, only one shielding part 2 is provided on the top cover 4, and in other cases, a plurality of shielding parts 2 can be provided on the top cover 4 at the same time, and the plurality of shielding parts 2 can be spliced together to form a whole, and the light transmittance of each shielding part 2 can be different, so that the perspective area of the top cover 4 can be adjusted. The plurality of shielding parts 2 can also be arranged at intervals, for example, in a mouth-shaped manner, which is considered that when the child lies flat in the carrying space with the face upward, if the entire top cover 4 is made to be light-transmissive, the child's eyes may be uncomfortable due to light stimulation, and if the shielding parts 2 are arranged dispersedly to avoid the central position of the top cover 4, the child's state can be observed from the shielding parts 2 when the accompanying person has the observation demand, and there is no need to worry about the stimulation of light to the child's eyes.
[0056] It should be understood that the size of the top cover 4 can be consistent with the size of the carrying seat 1, or can be different, for example, in the embodiment of the present application, Figure 1 the size of the top cover 4 is smaller than the size of the carrying seat 1.
[0057] It should be understood that the carrier 100 can be composed of only the plurality of side frames 3a located on the side of the carrying seat 1, or can be composed of the plurality of side frames 3a located on the side and the top of the carrying seat 1.
[0058] It should be noted that the sizes of the plurality of side frames can be consistent or different, which is considered for different modeling designs, for example, in the embodiment of the present application, Figure 1 the sizes of two opposite side frames 3a are consistent, and the sizes of the other two side frames 3a are different. That is, the frame 3 can be regular or irregular in shape.
[0059] It should be noted that the shape of each side frame 3a can be a square, a rectangle, a trapezoid or other regular polygonal pattern, or can be an irregular pattern, and the present application does not limit this.
[0060] In the embodiment, considering the uncertainty of the position of the carrier 100 and the accompanying person when the carrier 100 is used, the shielding part 2 is arranged at the corresponding position of the frame 3 on the side or the top.
[0061] One shielding part 2 can be arranged on each side frame 3a, and the size of the shielding part 2 can completely cover the entire side frame 3a, or the size of the shielding part 2 can only correspond to a part of the side frame 3a, for example, the shielding part 2 can correspond to the central region of the side frame 3a or the edge region of the side frame 3a. A plurality of shielding parts 2 can also be arranged on each side frame 3a. In one case, considering that the manufacturing processes of different structural forms of the shielding part 2 are different, the maximum size that can be achieved by the manufacturing process of a single shielding part 2 can not match the size of the side frame 3a, or the cost and easy procurement of raw materials are limited, and the cost increase caused by the excessive size of the single shielding part 2 is relatively large, so a plurality of shielding parts 2 can be arranged to abut each other to cover the entire side frame 3a after splicing. In another case, although a plurality of shielding parts 2 are arranged on each side frame 3a, the plurality of shielding parts 2 are arranged in a spaced manner, which can be arranged along the circumference, arranged along the straight line, or staggered, corresponding to different positions.
[0062] In one embodiment, please refer to Figure 1 and Figure 3 The front-to-back direction and the up-to-down direction are used as the direction reference for the description of each part. The carrier 100 is composed of an upper support assembly, a front canopy assembly 31, a front support assembly 32, a bottom support assembly, and a rear support assembly 33. The bottom support assembly forms the bearing seat 1. The bottom support assembly, the upper support assembly, the front support assembly 32, and the rear support assembly 33 are connected to each other to form the frame 3. The end of the front canopy assembly 31 is rotationally connected to the upper support assembly, so as to be arranged at an angle with the front support assembly 32 or embedded in the front support assembly 32. The part of the front support assembly 32 corresponding to the front canopy assembly 31 is arranged in an open manner to form the entrance and exit a. The front canopy assembly 31, the upper support assembly, the rear support assembly 33, and the opposite sides of the front support assembly 32 are provided with the shielding part 2.
[0063] It should be understood that, considering that the front canopy assembly 31 is a movable part, it has a supporting state in which the entrance and exit a are opened by rotating, and a closing state in which the entrance and exit a are closed by rotating, and therefore the corresponding compatibility should be considered, that is, the size should be adapted to the supporting and closing of the front canopy assembly 31, and the connection should be good in the closing state and the supporting state, so as to play the shielding function. Therefore, when the shielding part 2 is arranged, it should be considered that the action of rotating will not cause the shielding part 2 to be wrinkled when the front canopy assembly 31 is supported and closed, so as to avoid damage to the shielding part 2.
[0064] The utility model disc not limit the specific form of the light control of the shielding part 2, and the structure form of the shielding part 2 can be film or glass, and the core of light control is the discoloration material. The discoloration material can be divided into photochromic, electrochromic, thermochromic and liquid-crystal-based according to different action principles.
[0065] In one embodiment, the shielding part 2 includes electrochromic film. The electrochromic film is a film that can adjust the light passing state. It mainly works between scattering state and transparent state. That is, the film itself can change between transparent and non-transparent state, and the transparency of the electrochromic film is adjusted by voltage, for example, PDLC (Polymer Dispersed Liquid Crystal) is a material with electro-optic response characteristics obtained by mixing low molecular liquid crystal (Liquid Crystal, abbreviated as LC) with prepolymer, uniformly dispersing micron-sized liquid crystal droplets in the polymer network under certain conditions through polymerization reaction. When the electrochromic film is powered off, the high molecular liquid crystal material in it is arranged in disorder, so that the light cannot penetrate the film, and the effect seen at this time is the opaque state of milky white. When the electrochromic film is powered on, the high molecular liquid crystal material in the middle of the film is arranged in order under the action of electric field, so that the light can penetrate the film, and the effect seen at this time is the transparent and colorless film state.
[0066] In another embodiment, the shielding part 2 includes electrochromic glass, which is usually composed of ordinary glass and several layers of thin film material deposited on the glass. The layers are transparent conductive layer (TC), electrochromic layer (EC), ion conductor layer (IC), counter electrode layer (CE) or ion storage layer and another transparent conductive layer (TC) in order. The EC layer is the core part of the electrochromic glass. The TC layer serves as a lead electrode, and the CE layer is used to provide and store the ions required for discoloration. The IC layer is used to conduct the ions in the discoloration process.
[0067] In another embodiment, the shielding part 2 includes photochromic film. The photochromic film is because some compounds in its material change the molecular structure under the action of light of certain wavelength and intensity, resulting in the corresponding change of the absorption peak of light, i.e. color, and this change is generally reversible. The existing silver halide (AgX) is combined with light polymer-based material.
[0068] In other embodiments, the shielding part 2 comprises a thermochromic film, and various reversible thermochromic materials such as inorganic, organic, polymer and biological macromolecule have been developed. The material of the thermochromic film comprises at least two substances with different refractive indexes. At a low temperature, the substances are mixed at a molecular level by intermolecular forces to form a homogeneous phase, and the material is transparent. As the temperature rises, the molecular thermal motion intensifies, and when the temperature rises to a certain value, phase separation occurs to form countless fine particles. The incident light is strongly scattered, and because most of the light is diffusely reflected, the material becomes opaque white at this time. For example, a thin film based on vanadium oxide VO has a phase transition temperature of 68℃. When the temperature is lower than 68℃, VO is in a monoclinic crystal structure, and when the temperature is higher than 68℃, VO is in a tetragonal crystal structure. Due to the change of crystal structure, the optical properties of VO change greatly, and this change is reversible. Because the phase transition temperature of the thin film changes with the preparation method and process of the thin film, doping technology, fluorination technology or a method of reducing surface stress can be used to reduce the phase transition temperature of the thin film. The commonly used doping elements at present include niobium, molybdenum, tungsten and the like, which are plated to form a VO thin film with a phase transition temperature of 38℃.
[0069] Further, the shielding part 2 comprises at least one of an electrochromic film, a photochromic film and a thermochromic film. When a plurality of shielding parts 2 are provided, the plurality of shielding parts 2 can be formed in the same way or differently.
[0070] In the embodiment of the utility model, the shielding part 2 comprises an electrochromic film, in order to realize the control of electrochromic film, the carrier still includes control device 5, control device 5 is electrically connected with electrochromic film, to control the transparency transformation of electrochromic film. The shielding part 2 is electrified outside, and it can be transformed between the light transmission state and the light shielding state by artificial control. When setting, the corresponding button can be designed as the operating knob of control device 5, so as to adjust the light transmission of shielding part 2.
[0071] Specifically, the control device 5 can be arranged on the bearing seat 1 or the frame 3. In the embodiment, the carrier 100 further has a push handle 7 rotatably installed on the frame 3, and the control device 5 is arranged on the frame 3 near the push handle 7, so that the control device 5 can be conveniently controlled during pushing.
[0072] Specifically, the push handle 7 is rotatably installed on the rear side of the frame 3 and near the top of the frame 3, and the control device 5 is arranged on the top of the frame 7.
[0073] Based on the principle of electrochromic light, the utility model does not limit the specific material of the shielding part 2. For example, the shielding part is one of a liquid crystal light control film, an inversion mode light control film, an electrochromic light control film and a one-way perspective light control film.
[0074] Correspondingly, when the shielding part 2 is provided with multiple shielding parts, the control device 5 is electrically connected with different shielding parts 2 through different wire harnesses to enable the control device 5 to independently control different shielding parts 2. Thus, the light transmission of multiple shielding parts 2 can be controlled through centralized control.
[0075] The carrier 100 can be a fixed carrier 100 or a movable carrier 100, and in some embodiments, the bottom of the carrier seat 1 is provided with a rolling structure 6. The rolling structure 6 is a wheel assembly, so that the carrier 100 can move. In the embodiment of the present application, the bottom of the carrier seat 1 is provided with four wheels, two wheels on the front side are universal wheels that can change the direction of travel at will, and two wheels on the rear side are directional wheels that cooperate with the front wheels.
[0076] It should be understood that for different application scenarios of the carrier 100, the multiple wheels can be different in configuration. For example, when the carrier 100 is used as a scooter, the diameters of the two wheels on the rear side are greater than the diameters of the two wheels on the front side, so as to adapt to movement. When the carrier 100 is used as a stroller, the diameters of the four wheels are the same.
[0077] Based on the above embodiment, the carrier 100 includes a tow bar assembly 8 arranged at the other side end of the carrier seat 1. Through cooperation of the tow bar assembly 8 and the rolling structure 6, the carrier 100 can be used as a scooter. When in use, the tow bar assembly 8 is hung on a bicycle, so that the carrier 100 can be moved synchronously while the bicycle is ridden, thereby facilitating outdoor activities.
[0078] In the embodiment of the present application, the carrier 100 includes the rolling structure 6, the push handle 7 and the tow bar assembly 8, i.e., the carrier 100 is a tow-and-pull integrated vehicle, thereby adapting to different use scenarios. It should be understood that considering the conversion of different scenarios, the push handle 7 can be rotatably connected, so as to be foldable and storable, and the tow bar assembly 8 can be detachably connected, so as to be detachable when the carrier 100 is used only as a stroller.
[0079] In an embodiment of the utility model, the carrier 100 is a drag and pull integrated vehicle, the front and back direction, the up and down direction are regarded as the direction reference to describe each part, the carrier 100 is formed by push handle 7, upper support assembly, front canopy assembly 31, front support assembly 32, drag lever assembly 8, bottom support assembly, rear support assembly 33 and front and back wheel assembly. Bottom support assembly forms the bearing seat 1, upper support assembly forms the top cover 4, front support assembly 32, rear support assembly 33 and front canopy assembly 31 are all regarded as side frame body, the opposite sides of front canopy assembly 31, upper support assembly, rear support assembly 33 and front support assembly 32 are all provided with shielding part 2, and each shielding part 2 is different in size according to its setting position, is assembled to each support assembly by cloth cover b. Multiple shielding parts 2 are all provided with electrochromic film, control device 5 and rear support assembly 33 are fixedly connected, and are located at the position opposite to push handle 7 of rear support assembly 33, to make the accompanying person convenient to control the light transmittance while holding push handle 7. The distributed control circuit is arranged in the carrier 100 to connect control device 5 and multiple shielding parts 2, and the shielding part 2 at each position is changed to light transmission state and light shielding state by artificial control control device 5.
[0080] During use, the accompanying person can change the corresponding light transmittance according to the position.
[0081] In some embodiments, at least one side frame body can be movably arranged, so that the side corresponding to the movably arranged side frame body of the bearing space is formed with an entrance a; the movably arranged side frame body is provided with a shielding part 2. The utility model does not limit the activity form of the side frame body, which can be top or bottom rotary connection, so that it can be turned in the up and down direction, or the opposite side can be rotary connection, so that the entrance a can be opened.
[0082] Specifically, the movably arranged side frame body is provided as a front canopy assembly, and the front canopy assembly 31 includes first extension segment 311 and second extension segment 312 arranged at an angle, so that a larger space is formed between the front canopy assembly 31 and the bearing seat 1 when the front canopy assembly 31 is opened or closed, and a larger seating space can be provided for children when the seat 2 is unfolded.
[0083] It should be noted that the opening angle of the entrance a can be adjusted, i.e. the unfolding angle of the front canopy assembly 31 can be adjusted, so that the front canopy assembly 31 can be fixed at the required position as needed. It should be understood that a corresponding limiting stop structure needs to be provided to fix the front canopy assembly 31 at a certain angle gear, and the specific structure form is not limited in the utility model.
[0084] In the structure of the front canopy assembly 31, the front canopy assembly 31 can be in an L shape, and the first extension section 311 and the second extension section 312 are circularly arc transitioned. In other embodiments, the second extension section 312 can also be provided in an arc shape, so that a part of the second extension section 312 protrudes in a direction away from the back plate 22, so that the riding space is larger.

When the child sits in the carrying space, according to different sitting orientations, if sitting towards the direction of the front canopy assembly 31, if it is needed to enable the child to observe the external environment, the shielding part 2 in front of and on the side of the line of sight can be made to be in a light-transmitting state, that is, the shielding part 2 at the front canopy assembly 31 and the shielding part 2 on the front support assembly 32 are controlled to change into a transparent or translucent state, so that the shielding part 2 changes into a see-through state, and the shielding part 2 at other positions remains in a light-shielding state; if sitting towards the direction of the rear support assembly 33, the shielding part 2 in front of and on the side of the line of sight can be made to be in a light-transmitting state, that is, the shielding part 2 at the rear support assembly 33 and the shielding part 2 on the front support assembly 32 are controlled to change into a transparent or translucent state, so that the shielding part 2 changes into a see-through state, and the shielding part 2 at other positions remains in a light-shielding state.
[0092] It should be noted that the structure of the above-mentioned carrier 100 can also be set to a foldable structure, that is, the carrying seat 1 is rotationally connected with part of the side frame body, and the top cover 4 is rotationally connected with part of the side frame body.
[0093] In one embodiment, the carrier 100 is composed of a bottom support assembly, a front support assembly 32 and a rear support assembly 33, the rear support assembly 33 is composed of a rotationally connected upper support rod and a lower support rod, the bottom support assembly extends in the front-rear direction, the front support assembly 32 and the rear support assembly 33 each extend in the up-down direction, the lower part of the lower support rod is rotationally connected with the rear part of the bottom support assembly, the upper part of the lower support rod is rotationally connected with the lower part of the upper support rod, the lower part of the front support assembly 32 is rotationally connected with the front part of the bottom support assembly, and the upper part of the front support assembly 32 is rotationally connected with the upper support rod. The carrier 100 has a large seating space in the unfolded state, and the carrying space is located in the seating space, which can improve the comfort of the child riding. When the carrier 100 is folded, the front support assembly 32 is folded back and stored above the bottom support assembly, and the upper support rod and the lower support rod are relatively folded and stacked between the front support assembly 32 and the bottom support assembly, which significantly reduces the size and provides convenience for daily storage and carrying of the user.
[0094] Specifically, the bottom support assembly includes two groups of bottom support rods arranged on the left and right sides and extending in the front-rear direction, the front part of each group of bottom support rods is provided with a front wheel assembly, and the rear part is provided with a rear wheel assembly, and the front wheel assembly and the rear wheel assembly jointly form a rolling structure 6. The front support assembly 32 includes two front support rods arranged on the left and right sides and extending in the up-down direction, the front support rod has a certain curvature, the lower support rod is provided with two, arranged on the left and right sides and extending in the up-down direction, and the upper support rod is provided with two, arranged on the left and right sides and extending in the up-down direction. The push handle 7 includes two push handle rods arranged on the left and right sides.
