Description

Technical Field

[0001] The present invention relates to the technical field of a handle structure with a display function, and in particular to a handle structure with a display function that utilizes a solar cell to convert light energy into electrical energy to provide a display device with display information. Background Art

[0002] Public transportation is already a very common means of transportation, so the public spaces within carriages are actually very good places for promotional advertising, such as on the walls of the carriages or on hanging handles.

[0003] Suspended handles are a very good way to promote products because they are sure to be touched by passengers. For example, festival notices, carriage instructions, advertising materials, etc. can be placed on them. However, in the past, advertising content was presented by drawing it on cardboard. This not only requires replacing the cardboard multiple times, but also increases hardware costs and causes environmental pollution.

[0004] Patent Nos. CNB-204659530 and CNB-214189427U both provide a handle design that supplies power to a display device to display content through a piezoelectric method. Although such a design can eliminate the use of paper and reduce environmental pollution, the so-called piezoelectric method provides power to the display device through a voltage difference. That is to say, when a passenger holds the handle for a long time, no voltage difference will be generated, which will cause the display device to be unable to display, or when no passenger uses the handle, the handle has no power to allow the display device to display information. In other words, the passenger can only hold the handle and pull it repeatedly in order for the handle to continuously generate power to provide power to the display device.

[0005] Some current public transportation vehicles also use handle structures with display devices to display information, wherein the handle structures mostly use a power module such as a dry cell or a rechargeable battery to supply the energy required for the liquid crystal screen to display information. However, the disadvantage of using dry cells or rechargeable batteries to provide power is that the relevant staff must remove the entire handle structure from the crossbar of the car at regular intervals to replace the dry cells or charge the rechargeable batteries. This not only consumes manpower and material resources, but also when the power of the dry cells or rechargeable batteries is about to run out, it may also cause the effect of information display to be greatly reduced, for example: the brightness of the display device becomes dim or the displayed image becomes unclear.

[0006] Therefore, in order to reduce the increase in hardware and labor costs caused by multiple replacements of advertising paper or power sources, it is necessary to develop an ideal technical approach to solve the above problems. Summary of the invention

[0007] The purpose of the present invention is to provide a handle structure with a display function, which can be held by passengers to maintain balance in the compartment of a public transportation vehicle. Its greatest feature is that a power unit or a transducer unit in the form of a solar cell is used to continuously provide power to a display device, so that the display device can display images uninterruptedly, so that passengers can receive relevant information about the ride, popular advertisements, or various advocacy slogans when riding in public transportation, and can further effectively save the hardware cost of frequently replacing batteries and the labor cost of regularly changing information content.

[0008] The present invention relates to a handle structure with display function, which is hung on a crossbar in a public transportation tool. The handle structure with display function includes at least a shell, at least one display device, and at least one power unit.

[0009] The shell has an accommodating space inside and a gripping portion extending through the shell. Passengers can hold the gripping portion to maintain balance in the vehicle when riding in public transportation.

[0010] The display device is disposed in the accommodating space. The display device includes a display surface exposed from a side surface of the shell. The display surface is assembled at an end of the gripping portion and is used to display a picture.

[0011] The power unit is arranged around the surface of the shell and is electrically connected to the display device. The power unit receives ambient light and generates electrical energy to provide energy for the display device to display the picture.

[0012] The shell is further formed by a first cover body and a second cover body correspondingly covering each other, and the accommodating space is surrounded by the first cover body and the second cover body. That is to say, when the first cover body and the second cover body are correspondingly covered, the accommodating space will be generated in the shell.

[0013] The display device is a cholesterol liquid crystal display device (Cholesteric Liquid Crystal Display, CLCD), which has the functions of eye protection and environmental protection. At the same time, there is no need to manually replace the display surface, and different display contents can be provided on the display surface according to needs, such as manufacturer's advertising materials, or riding instructions, etc.

[0014] The handle structure with a display function further includes two display devices, and the display surfaces of the two display devices are respectively exposed from the two side surfaces of the shell. In other words, the display surfaces of the two display devices can face the corresponding two sides according to the setting of the handle structure with a display function, so that all passengers in the car can watch and receive the displayed information.

[0015] The display device further includes a transducer unit, which is arranged on the other end surface of the display device corresponding to the display surface. The transducer unit receives ambient light that penetrates the display device and generates electrical energy to provide energy for the display device to display the image.

[0016] The energy conversion unit includes a light absorbing surface facing the display surface, and the light absorbing surface absorbs the ambient light penetrating the display surface and generates electric energy to provide energy for the display device to display the picture.

[0017] The handle structure with display function further includes an energy storage unit arranged in the accommodating space, and the energy storage unit is electrically connected to the power unit and the display device respectively. The energy storage unit stores the energy generated by the power unit and provides it to the display device for use. That is to say, when the power unit generates a large amount of electrical energy, it can be temporarily stored in the energy storage unit. When it is needed, the energy storage unit will provide electrical energy to the display device to display the picture.

[0018] The energy storage unit is a device such as a battery or a capacitor. When the power unit generates a large amount of electrical energy, it can be temporarily stored in the energy storage unit. When it is needed, the energy storage unit will provide electrical energy to the display device to display the image.

[0019] The energy storage unit may also be electrically connected to the energy conversion unit to store the energy generated by the energy conversion unit.

[0020] Furthermore, in the vehicle, when the road conditions are rough, passengers will inevitably accidentally touch any part of the handle structure with display function. The surface of the power unit can be further covered with a light-transmitting protective shell to properly protect the power unit.

[0021] The shell is further assembled on the cross bar through a connecting piece, so that the handle structure with display function can be extended from the cross bar for passengers to hold when riding.

[0022] Furthermore, the present invention may also be a handle structure with a display function, which is arranged on a crossbar in a public transportation vehicle. The handle structure with a display function includes at least a shell and at least one cholesterol liquid crystal display device.

[0023] The shell has an accommodating space inside and a gripping portion passing through the shell.

[0024] The cholesterol liquid crystal display device is arranged in the accommodating space, and one end surface of the cholesterol liquid crystal display device is provided with a display surface, and the other end surface is provided with a transducer unit, wherein the display surface is exposed from one side surface of the shell and displays a picture, and the transducer unit receives the ambient light that penetrates the cholesterol liquid crystal display device and generates electrical energy to provide energy for the cholesterol liquid crystal display device to display the picture.

[0025] The shell is further formed by correspondingly covering a first cover and a second cover, and the accommodating space is surrounded by the first cover and the second cover.

[0026] The handle structure with display function further includes two display devices, and the display surfaces of the two display devices are respectively exposed from two side surfaces of the shell.

[0027] The energy conversion unit includes a light absorbing surface facing the display surface, and the light absorbing surface absorbs the ambient light penetrating the display surface and generates electric energy to provide energy for the display device to display the picture.

[0028] The handle structure with display function further includes at least one power unit, which is arranged on the surface of the shell and electrically connected to the cholesterol liquid crystal display device. The power unit receives ambient light and generates electrical energy to provide energy for the cholesterol liquid crystal display device to display the picture.

[0029] The handle structure with display function further includes an energy storage unit arranged in the accommodating space, and the energy storage unit is electrically connected to the power unit, the transducer unit, and the cholesterol liquid crystal display device respectively. The energy storage unit stores the energy generated by the power unit and the transducer unit and provides it to the cholesterol liquid crystal display device for use.

[0030] Furthermore, the present invention may also be a handle structure with a display function, which is arranged on a crossbar in a public transportation vehicle. The handle structure with a display function includes at least a shell, at least one cholesterol liquid crystal display device, and at least one power unit.

[0031] The shell has an accommodating space inside and a gripping portion passing through the shell.

[0032] The cholesterol liquid crystal display device is arranged in the accommodating space, and one end surface of the cholesterol liquid crystal display device is provided with a display surface, and the other end surface is provided with a transducer unit, wherein the display surface is exposed from one side surface of the shell and displays a picture, and the transducer unit receives the ambient light that penetrates the cholesterol liquid crystal display device and generates electrical energy to provide energy for the cholesterol liquid crystal display device to display the picture.

[0033] The power unit is arranged around the surface of the shell and electrically connected to the cholesterol liquid crystal display device. The power unit receives ambient light and generates electrical energy to provide energy for the cholesterol liquid crystal display device to display the picture.

[0034] Therefore, the handle structure with display function provided by the present invention utilizes the interactive configuration of the power unit and the transducer unit to increase the amount of electricity obtained by the handle structure, and the energy storage unit can properly store the electricity generated by the power unit and the transducer unit, which can be used to display content on the display device in the future, thereby achieving the effect of not having to frequently change the power source, paperless, and energy saving and carbon reduction.

[0060] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments; the technical features designed in different implementation modes of the present invention described below can be combined with each other as long as they do not conflict with each other; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0061] In the description of the present invention, it should be understood that the terms "center", "lateral", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more. In addition, the term "including" and any variation thereof all mean "at least including".

[0062] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] The present invention relates to a handle structure with a display function. In addition to being able to be held by passengers to maintain balance in the compartment of a public transportation vehicle, its greatest feature is that a power unit or a transducer unit in the form of a solar cell is used to continuously provide power to a display device, so that the display device can display images uninterruptedly and there is no need to frequently replace batteries. Passengers can receive relevant information about riding public transportation, popular advertisements, or various advocacy slogans through the screen when riding public transportation, and further achieve the main advantages of saving hardware costs and labor costs for changing information content.

[0064] See also Figure 1 And with Figure 2 and Figure 3 , Figure 1 is a schematic diagram of a first embodiment of a handle structure of a display device according to the present invention, Figure 2 is a schematic diagram of the accommodation space of the present invention, Figure 3The present invention relates to a handle structure 10 with a display function, which is hung on a crossbar 1 in a public transportation vehicle, wherein the public transportation vehicle may be, for example but not limited to, a mass transportation vehicle such as a MRT, a train or a bus, and the handle structure 10 with a display function includes a housing 20, a display device 30, a transducer unit 40, an energy storage unit 60, and a power unit 50.

[0065] The shell 20 is formed by a first cover body 22 and a second cover body 24 correspondingly covering each other, and its interior includes a accommodating space 26, and the accommodating space 26 is surrounded by the first cover body 22 and the second cover body 24. That is to say, when the first cover body 22 and the second cover body 24 are correspondingly covered, the accommodating space 26 will be generated in the shell 20, and a grip portion 28 is penetrated through the shell 20. Passengers can hold the grip portion 28 when riding the public transportation vehicle to maintain balance in the car. It is worth noting that the grip portion 28 is opened on the shell 20 only as one of the preferred embodiments of the present invention. After reading and understanding the teachings of the present invention, those skilled in the art should know that the grip portion 28 may not be integrally formed with the shell 20, and it will not affect the actual implementation of the present invention.

[0066] The display device 30 is disposed in the accommodating space 26. Figure 2 The display device 30 is located at the first cover body 22, but in fact the display device 30 can also be located at the second cover body 24. The display device 30 includes a display surface 32 exposed from one side of the shell 20, and the display surface 32 is assembled at the upper end of the grip 28 and is used to display a picture.

[0067] The power unit 50 is arranged at any position on the surface of the shell 20 and is electrically connected to the display device 30, wherein the power unit 50 can be an external solar cell, which can provide energy for the display device 30 to display the image after receiving ambient light in the compartment of the public transportation vehicle and generating electrical energy.

[0068] The transducer unit 40 is arranged on the other end surface of the display device 30 corresponding to the display surface 32. The transducer unit 40 can be a built-in solar cell, which mainly receives the ambient light penetrating the display device 30 and generates electrical energy to provide the display device 30 with energy to display the picture. In other words, when the transducer unit 40 receives the ambient light penetrating the display device 30, it can provide electrical energy to the display surface 32 to produce the picture.

[0069] The energy conversion unit 40 includes a light absorbing surface 42 facing the display surface 32 . The light absorbing surface 42 receives the ambient light passing through the display surface 32 and generates electrical energy to provide energy for the display surface 32 to display the image.

[0070] The handle structure 10 with a display device includes an energy storage unit 60 arranged in the accommodating space 26. The energy storage unit 60 is electrically connected to the power unit 50 and the display device 30 respectively. The energy storage unit 60 stores the energy generated by the power unit 50 and provides it to the display device 30 for use. That is to say, when the power unit 50 generates a large amount of electrical energy, it can be temporarily stored in the energy storage unit 60. When the display device 30 needs energy, the energy storage unit 60 will provide electrical energy to the display device 30 to display the picture.

[0071] The energy storage unit 60 can also be electrically connected to the transducer unit 40 to store the energy generated by the transducer unit 40. That is to say, when the transducer unit 40 generates a large amount of electrical energy, it can be temporarily stored in the energy storage unit 60. When the display device 30 needs energy, the energy storage unit 60 will provide electrical energy to the display device 30 to display the image.

[0072] The energy storage unit 60 is a device such as a battery or a capacitor. When the power unit 50 generates a large amount of electrical energy, it can be temporarily stored in the energy storage unit 60. When the display device 30 needs energy, the energy storage unit 60 will provide electrical energy to the display device 30 to display the image.

[0073] Also, because the environment in which the handle structure 10 with a display device is located may be temporarily dark, if a permanent screen with a certain power consumption is to be used, the display device 30 needs to select a screen with lower power consumption. For example, the display device 30 can be a cholesterol liquid crystal display. In addition to having eye protection and environmental protection functions, the cholesterol liquid crystal display only needs to use electricity when switching screens, and there is no need to manually replace the display surface 32. Different display contents can be provided on the display surface 32 according to needs, such as manufacturer's advertising materials, or riding instructions, etc., thereby achieving the effect of saving electricity and labor.

[0074] During the driving of the public transportation vehicle, when the road conditions are bumpy, passengers will inevitably accidentally touch any part of the handle structure 10 with a display function. Since the surface of the power unit 50 is exposed to the outside of the shell 20, a light-transmitting protective shell 52 can be further provided on the surface of the power unit 50 to properly protect the solar cell components.

[0075] Furthermore, the housing 20 is assembled on the cross bar 1 by a connecting member 70, so that the handle structure 10 can be extended from the cross bar 1, and the passenger can then hold the grip 28 to maintain balance in the vehicle during driving.

[0076] See also Figure 4 And with Figure 1 , Figure 4 1 is a schematic diagram of a second embodiment of a handle structure with a display device of the present invention. In the second embodiment, the present invention is related to a handle structure with a display device 10, the handle structure with a display device 10 at least comprising a housing 20, a display device 30, two power units 50, and an energy storage unit 60, wherein the display device 30 is a cholesterol liquid crystal display.

[0077] The difference between the second embodiment and the first embodiment is that the second embodiment does not have a transducer unit. Because there is no transducer unit, in addition to reducing the overall weight of the handle structure 10 with a display device, the shell 20 can also be designed to be lighter and thinner. In addition, the power unit 50 can be a solar cell, and the energy storage unit 60 can be used to store electrical energy to provide it to the display device 30 for switching or displaying images.

[0078] See also Figure 5 And with Figure 1 , Figure 5 It is a schematic diagram of a third embodiment of a handle structure with a display device of the present invention, wherein the present invention relates to a handle structure 10 with a display device, and the handle structure 10 with a display device at least includes a shell 20, a display device 30, a transducer unit 40, and an energy storage unit 60.

[0079] The difference between the third embodiment and the first embodiment is that the third embodiment does not have a power unit, and the energy conversion unit 40 can be a solar cell. The energy conversion unit 40 interacts with the energy storage unit 60 to generate and store electrical energy, allowing the display device 30 to be replaced or displayed. Since the display device 30 is a cholesterol liquid crystal display, ambient light can pass through the display device 30 to enable the energy conversion unit to generate electrical energy, and the display device 30 can obtain sufficient electricity to switch or display images.

[0080] See also Figure 6 And with Figure 1 , Figure 6It is a schematic diagram of the fourth embodiment of the handle structure 10 with a display device of the present invention, wherein the present invention may also be related to a handle structure 10 with a display device, wherein the handle structure 10 with a display device at least includes a shell 20, a display device 30, a transducer unit 40, three power units 50, and an energy storage unit 60.

[0081] The power unit 50 is respectively installed on the first cover body 22 and the second cover body 24, or is installed on the front and rear seams of the first cover body 22 and the second cover body 24. This can increase the absorption of ambient light on both sides and double the power that can be provided. In order to protect the power unit 50, the outer side thereof also needs to be covered with a light-transmitting protective shell 52. Because the power unit 50 is an exposed precision component, the protective shell 52 is required to resist external damage.

[0082] See also Figure 7 And with Figure 1 , Figure 7 It is a schematic diagram of the fifth embodiment of the handle structure 10 with a display device of the present invention, wherein the fifth embodiment is the best embodiment of the present invention. The best embodiment is about a handle structure 10 with a display device, and the handle structure 10 with a display device includes at least a shell 20, two display devices 30, two transducer units 40, five power units 50 (some of which are not shown in the figure), and an energy storage unit 60.

[0083] Furthermore, the handle structure 10 with a display device includes two display devices 30, and the display surfaces 32 of the two display devices 30 are respectively exposed from two side surfaces of the shell 20. In other words, the display surfaces 32 of the two display devices 30 will respectively face the corresponding surfaces of the handle structure 10 with a display device, so that all passengers in the car can receive the information displayed by the display devices 30 together.

[0084] That is to say, in order to enhance the information dissemination effect, two display devices 30 can be installed on the handle structure 10 with a display device, so that passengers in the car can view the information displayed on the display surface 32, including ride information, popular advertisements, or official warnings, etc., to obtain the best publicity effect. Because there are two display devices 30, the advertising fees can be increased, and the cholesterol liquid crystal display is used, it is possible to achieve the effect of increasing revenue and reducing labor costs.

[0085] Because the amount of electricity required is greater, in addition to each of the display devices 30 having a corresponding transducer unit 40, five power units 50 can also be installed on the five surfaces of the shell 20. That is to say, except for the bottom surface that is less likely to receive ambient light, the other five surfaces can be respectively provided with the power units 50. The upper power unit 50 (not shown in the figure) can best receive the ambient light emitted by the light source in the car, and the power units 50 on the four middle surfaces (only three surfaces are shown in the figure) can best receive the ambient light irradiated by the windows of the car. The five power units 50 can be respectively covered with a light-transmitting protective shell 52. As mentioned above, because the power unit 50 is an exposed precision component, the protective shell 52 is required to resist external damage.

[0086] In summary, the handle structure 10 with a display function provided by the present invention can utilize the interactive configuration of the transducer unit 40 and the power unit 50 respectively through the above-mentioned embodiments, which can increase the amount of electricity obtained by the handle structure 10 with a display function. In addition, the energy storage unit 60 can be used to temporarily store the currently unused electricity. When needed in the future, electricity can be supplied to the display device 30 in real time to switch screens or display screens, thereby achieving the effect of paperless, energy-saving and carbon-saving, and increasing advertising revenue.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
