Description

Technical Field

[0001] The invention relates to the field of toys, in particular to a functional building block component. Background Art

[0002] Generally speaking, a building block assembly usually includes a plurality of building block components. Children can connect the building block components in various ways to achieve building block models of different shapes and forms, thereby helping children to develop their intelligence and enjoy the fun. Summary of the invention

[0003] Under the above background, the present invention proposes a functional building block component, through which children who assemble building blocks can not only develop their intelligence and enjoy the fun of assembling, but also realize corresponding additional functions. A functional building block component comprises: a first building block component, suitable for plugging with a second building block component; and a functional component, the functional component being accommodated in the first building block component; wherein, when the first building block component is plugged with the second building block component, the functional component is activated.

[0004] Advantageously, the functional component may include: a power source, a functional element, and a switch element. The power source may be configured as a battery, and of course other types of power sources suitable for matching the building block components are also conceivable. The power source, the functional element, and the switch element may be electrically connected, wherein when the first building block component and the second building block component are not plugged in, the switch element is in a normally-off state, and when the first building block component and the second building block component are plugged in, the switch element is triggered to be in a closed state, so that the power source, the functional element, and the switch unit form a closed loop, and the functional element is in a working state.

[0005] Advantageously, the first building block component may further include a first plug connector and a second plug connector, wherein the second building block component is configured to be plugged into the second plug connector, wherein a switch element may be provided on the second plug connector, and when the second building block component is plugged into the second plug connector, the switch element is triggered to a closed state.

[0006] Advantageously, the switch element can be configured as a spring sheet, and when the second building block is plugged into the second plug connector, the spring sheet is pushed to a closed state. The spring sheet can be configured as a metal sheet, such as a copper sheet, and naturally other types of metal wires for electrical conduction are also conceivable. Naturally, other types of switch elements with the same function are also conceivable.

[0007] Advantageously, the second building block component may include a third plug connector, which is suitable for being plugged into the second plug connector, and when the third plug connector is plugged into the second plug connector, the third plug connector pushes the spring piece to a closed state. More advantageously, the third plug connector has the same structure as the first plug connector.

[0008] Among them, the first plug connector can be a male connector, the second plug connector can be a female connector, and the third plug connector is a male connector.

[0009] Advantageously, the functional component may further include: a bracket, which may be made of an insulating material and is used to carry the power supply, the functional element and the switch element.

[0010] Advantageously, the first building block component may form a cavity, so that the bracket is suitable for accommodating and engaging in the cavity. Advantageously, after the functional component is taken out of the cavity of the first building block component, the power supply may be suitable for being removed from the bracket for replacement. Thus, good detachability may be achieved.

[0011] Advantageously, the first building block component may include a first plug connector and a second plug connector, wherein the first plug connector is a male connector and the second plug connector is a female connector. The second plug connector may be connected to the cavity to form an opening, and the power supply, the functional element, and the functional element may be first installed on the bracket to form the functional component, and then installed from the second plug connector into the cavity of the first building block component. This achieves a simple and orderly installation and is not prone to mis-installation and damage to the component.

[0012] Advantageously, when the functional component formed in the cavity of the first building block is taken out of the cavity of the first building block, it can be decomposed into the power supply, the functional element, the switch element and the bracket without being damaged. Advantageously, the connection between the first plug connector of the first building block and its main body can have an opening, and the functional element installed on the bracket can penetrate the opening and protrude into the first plug connector. More advantageously, the functional element penetrating the opening and protruding into the first plug connector does not extend beyond the end of the first plug connector opposite to the main body of the first building block. This ensures that the presence of the functional element does not affect the plugging of the building blocks.

[0013] Furthermore, advantageously, the first plug connector may also be adapted to be plugged into a fourth plug connector of the third building block, wherein the fourth plug connector may have the same structure as the second plug connector.

[0014] Advantageously, when the switch element is configured as a metal sheet, one end of the switch element is connected to one end of the functional element, the other end of the functional element is connected to the first pole of the power source, for example, the positive pole, the other end of the switch element is configured as a free contact spring end and is located at the bottom of the functional component as a whole, the second pole of the power source, that is, the negative pole is exposed to the bottom of the functional component as a whole, when the first building block component is plugged into the second building block component, the second building block component pushes the contact spring end of the switch element toward the bottom of the functional component to contact the second pole of the power source, that is, the negative pole, to form an electrical connection. Naturally, the first pole can also be configured as the negative pole of the power source in contrast to the above, while the second pole is configured as the positive pole of the power source.

[0015] Advantageously, in another case, as also described above, the switch element is configured as a metal sheet. In addition, the power supply may include a first power supply and a second power supply. Wherein, one end of the switch element is connected to the first pole of the first power supply, such as the positive pole; and the second pole of the first power supply is connected to one end of the functional element; and the other end of the functional element is connected to the first pole of the second power supply, such as the positive pole; and the second pole of the second power supply, i.e., the negative pole, is exposed to the side of the functional component as a whole; and the other end of the switch element is configured as a free contact spring end and is located on the side of the functional component as a whole and corresponds to the position of the second pole of the second power supply, i.e., the negative pole. Then, when the first building block component is plugged with the second building block component, the second building block component pushes the contact spring end inward in a direction perpendicular to the plugging direction, so that the contact spring end contacts the second pole of the second power supply, i.e., the negative pole, to form an electrical connection. Naturally, as also described above, the first pole can also be configured as the negative pole of the power supply inversely thereto, while the second pole is configured as the positive pole of the power supply.

[0016] Advantageously, the functional component may further include a connection circuit, and the connection circuit and the switch element may both be configured as metal sheets. One end of the connection circuit is connected to the first pole of the power supply, such as the positive pole; and the other end of the connection circuit is connected to one end of the functional element; and the other end of the functional element is connected to one end of the switch element; and the other end of the switch element is configured as a free contact spring end and is located on the side of the functional component as a whole. The second pole of the power supply, i.e., the negative pole, is exposed to the side of the functional component as a whole; the free spring end corresponds to the second pole of the power supply, i.e., the negative pole position. Thus, when the first building block component is plugged into the second building block component, the second building block component pushes the contact spring end inward in a direction perpendicular to the plugging direction, so that the contact spring end contacts the second pole of the second power supply, i.e., the negative pole, to form an electrical connection. Naturally, as described above, the first pole may also be configured as the negative pole of the power supply inversely, while the second pole is configured as the positive pole of the power supply.

[0017] Advantageously, the functional component can be an activatable light fixture. Thus, when the first building block component and the second building block component are plugged into each other, the internal circuit of the light fixture is closed, so that the light fixture is lit and activated. Naturally, in this case, the first building block component is transparent or translucent, so that the light of the light fixture can be radiated through the first building block component.

[0018] In addition, the light emitting lamp can be configured as a correspondingly matched LED lamp, and naturally other types of light emitting lamps suitable for toys are also conceivable. When the power supply, the switch element and the light emitting lamp are electrically connected, the light emitting lamp is activated to emit light.

[0019] Therefore, the concept of the above-mentioned embodiment is that when the first building block component and the second building block component are completely plugged into each other, the power supply, the switch element and the LED lamp are electrically connected, so that the LED lamp is in a light-emitting state; conversely, when the first building block component and the second building block component are not completely plugged into each other, the power supply, the switch element and the LED lamp are electrically disconnected, so that the LED lamp is in a non-working state, that is, a non-light-emitting state.

[0020] Advantageously, it is also conceivable that the functional component can be configured as other types of functional components, such as a speaker, a music playing module, etc. Thus, when the first building block component and the second building block component are not plugged into each other, the corresponding speaker, the music playing module, etc. are in an inactive state and do not perform the corresponding function; on the contrary, when the first building block component and the second building block component are plugged into each other, the corresponding speaker, the music playing module reaches an activated state and starts to perform the corresponding function, such as emitting a sound or playing the corresponding music, and so on.

[0028] The functional building block component 100 proposed according to the present invention is explained in detail below according to three specific embodiments. In these three embodiments, the functional building block component 100 includes: a first building block component 10 and a functional component 30, wherein the first building block component 10 is suitable for plugging with the second building block component 20, wherein the functional component 30 is accommodated in the first building block component 10, and when the first building block component 10 and the second building block component 20 are plugged into each other, the functional component 30 can be activated. According to these three embodiments, the first building block component 10 and the second building block component 20 respectively have the same male head and female head, so that they can be plugged into each other.

[0029] Specifically, the first building block component 10 and the second building block component 20 can be configured as a hollow cylinder having a male head and a female head that can be plugged into each other and made of an insulating material such as plastic. The functional component 30 can be configured as an activatable light fixture 30 .

[0030] Specifically, the light emitting lamp 30 may include a power supply 1, a light emitting element 2, a bracket 3 and a switch element 4. The lower part of the first building block component 10 forms a cavity, and the bracket 3 is suitable for accommodating and engaging in the cavity. In addition, the female head of the first building block component 10 is connected with the middle cavity to form an opening, and the power supply 1, the functional element 2, and the switch element 4 can be first installed on the bracket 3 to form the functional component 30, and then installed in its cavity through the female head of the first building block component 10. It goes without saying that when the functional component 30 installed in the cavity of the first building block component 10 through the female head is taken out from the cavity of the first building block component 10, it can naturally be decomposed into the power supply 1, the functional element 2, the switch element 4 and the bracket 3 without being damaged. Therefore, in this case, it is suitable to remove the power supply 1 from the bracket 3 in this way for replacement.

[0031] Figure 1aAn exploded view of a light emitting lamp 30 as a functional component 30 of a functional building block component 100 according to a first embodiment of the present invention is shown. Among them, the power supply 1 is configured as two batteries 1 connected in series up and down. The switch element 4 is configured as a copper metal sheet 4. The bracket 3 is composed of an insulating material and is used to carry the battery 1, the switch element 4 and the light emitting element 2 configured as an LED. When the battery 1, the switch element 4 and the LED lamp 2 are electrically connected, the LED lamp 2 is activated and emits light.

[0032] Figure 1b and 1c Schematic cross-sectional structural diagrams of a functional building block 100 according to a first embodiment of the present invention are shown in two states. Figure 1b A schematic diagram of the functional building block 100 is shown in a state where the first building block 10 and the second building block 20 are not plugged in, wherein the upper end of the switch element 4 is connected to one end of the LED lamp 2, and the other end of the LED lamp is connected to the positive pole of the upper battery 1 of the two batteries 1 connected in series. In addition, the other end of the switch element 4 is configured as a free contact spring end and is located at the bottom of the entire light-emitting lamp 30 and slightly droops downward at an acute angle, so as to keep it from contacting the negative pole of the lower battery in the battery 1, so that the internal circuit of the light-emitting lamp 30 is disconnected as a whole, and the LED lamp 2 is in an unactivated state and does not emit light. Among them, the negative pole of the power source 1 is exposed to the bottom of the entire light-emitting lamp 30. When the first building block 10 and the second building block 20 are plugged in, the second building block 20 pushes the free contact spring end of the switch element 4 toward the bottom of the light-emitting lamp 30 to contact the negative pole of the power source 1 to form an electrical connection. Of course, in other embodiments, the installation directions of the positive and negative poles of the power source 1 can be interchanged.

[0033] like Figure 1c It can be seen that when the second building block 20, i.e., its male head, is inserted into the first building block 10, i.e., its female head, from the bottom and the plugging is completed, the top of the male head of the second building block 20 is pressed, so that Figure 1bThe end of the contact spring in a slightly downward drooping state is upward and contacts the negative electrode of the battery below, so that the internal circuit of the light-emitting lamp 30 is closed, so that the LED lamp 2 is activated and emits light. That is, the second building block component 20 does not need to have any electrical structure. As long as the male head of the second building block component 20 is plugged into the female head of the first building block component 10, the circuit of the light-emitting lamp 30 in the first building block component 10 can be closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. The male head of the first building block component 10 and the male head of the second building block component 20 have the same structure, the female head of the first building block component 10 and the female head of the second building block component 20 have the same structure, and even the first building block component 10 and the second building block component 20 have the same structure, that is, the first building block component 10 and the second building block component 20 can be standard parts and can be replaced with each other, and there is no need to make special changes or designs to the building blocks or the male and female heads.

[0034] In addition, by Figure 1c It can be seen that there is an opening at the connection between the male head of the first building block component 10 and its main body, and the functional element 2, that is, the LED lamp 2 installed on the bracket 3, penetrates the opening and protrudes into the male head, and the light of the LED lamp 2 can also be transmitted to the outside of the first building block component 10 through the opening. When the male head of the first building block component 10 is plugged into another transparent or light-transmissive third building block component, the light of the LED lamp 2 can also be radiated through the third building block component. Of course, the first building block component 10 itself can also be transparent, and the light of the LED lamp 2 can be radiated through the first building block component 10. Furthermore, the LED lamp 2 that penetrates the above-mentioned opening and protrudes into the male head does not exceed the end of the male head opposite to the main body of the first building block component 10, which, on the one hand, plays a role in protecting the LED lamp 2, and on the other hand, does not affect the plugging of the male head of the first building block component 10 with another building block component.

[0035] Figure 2aAn exploded view of a light emitting lamp 30 as a functional component 30 of a functional building block according to a second embodiment of the present invention is shown. Among them, the power supply 1 is constituted by two batteries 1 arranged on the left and right but not directly connected in series. The switch element 4 is also constituted by a copper metal sheet 4. The bracket 3 is also constituted by an insulating material and is used to carry the battery 1, the switch element 4 and the light emitting element 2 constituted as an LED. As in the first embodiment, when the battery 1, the switch element 4 and the LED lamp 2 are electrically connected, the LED lamp 2 is activated and emits light. That is, the second building block component 20 does not need to have any electrical structure. As long as the male head of the second building block component 20 is plugged into the female head of the first building block component 10, the circuit of the light emitting lamp 30 in the first building block component 10 can be closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. The male head of the first building block component 10 and the male head of the second building block component 20 have the same structure, the female head of the first building block component 10 and the female head of the second building block component 20 have the same structure, and even the first building block component 10 and the second building block component 20 have the same structure, that is, the first building block component 10 and the second building block component 20 can be standard parts and can be replaced with each other, without any special changes or designs to the building block components or the male and female heads.

[0036] Figure 2b and 2c Schematic cross-sectional structural diagrams of a functional building block 100 according to a second embodiment of the present invention are shown in two states. Figure 2b The schematic diagram of the building block 100 is shown in a state where the first building block 10 and the second building block 20 are not plugged in, wherein one end of the switch element 4 is connected to the negative electrode of the right battery 1, and the positive electrode of the right battery 1 is connected to one end of the LED lamp 2, and the other end of the LED lamp 2 is connected to the negative electrode of the left battery 1. In addition, the other end of the connecting line 4 is on the side of the entire light emitting lamp 30 (at Figure 2b The positive electrode of the left battery 1 is exposed to the side of the entire light fixture 30 and its position corresponds to the end position of the free contact spring of the switch element 4.

[0037] like Figure 2c As shown, when the first building block 10 is inserted into the second building block 20 from the bottom and the two building blocks are inserted into each other, the top of the second building block 20 is pressed so that Figure 2bThe free end of the contact spring is deflected inward and contacts the positive electrode of the left battery 1, so that the internal circuit of the light emitting lamp 30 is closed, so that the LED lamp 2 is activated and emits light. Of course, in other embodiments, the installation directions of the positive and negative electrodes of the power source 1 can be interchanged.

[0038] In addition, by Figure 2c It can be seen that there is an opening at the connection between the male head of the first building block component 10 and its main body, and the functional element 2, that is, the LED lamp 2 installed on the bracket 3, penetrates the opening and protrudes into the male head, and the light of the LED lamp 2 can also be transmitted to the outside of the first building block component 10 through the opening. When the male head of the first building block component 10 is plugged into another transparent or light-transmissive third building block component, the light of the LED lamp 2 can also be radiated through the third building block component. Of course, the first building block component 10 itself can also be transparent, and the light of the LED lamp 2 can be radiated through the first building block component 10. Furthermore, the LED lamp 2 that penetrates the above-mentioned opening and protrudes into the male head does not exceed the end of the male head opposite to the main body of the first building block component 10, which, on the one hand, plays a role in protecting the LED lamp 2, and on the other hand, does not affect the plugging of the male head of the first building block component 10 with another building block component.

[0039] also, Figure 3a The exploded view of the light emitting lamp 30 as the functional component 30 of the functional building block component according to the third embodiment of the present invention is shown. Among them, as in the first embodiment, the power supply 1 is constituted by two batteries 1 connected in series. The switch element 4 is also constituted by a copper metal sheet 4, and the difference from the above-mentioned second embodiment is that the functional component 30 also includes a connecting line, and the connecting line and the switch element 4 are both metal sheets. The bracket 3 is also constituted by an insulating material and is used to carry the battery 1, the switch element 4, the connecting line and the light emitting element 2 constituted as an LED. Similarly, as similar to the first and second embodiments, when the battery 1, the switch element 4, the connecting line and the LED lamp 2 are electrically connected, the LED lamp 2 is activated and emits light. That is, there is no need for the second building block component 20 to have any electrical structure. As long as the male head of the second building block component 20 is plugged into the female head of the first building block component 10, the circuit of the light emitting lamp 30 in the first building block component 10 can be closed, and a loop is formed by itself, so that the LED lamp 2 is activated and emits light. The male head of the first building block component 10 and the male head of the second building block component 20 have the same structure, the female head of the first building block component 10 and the female head of the second building block component 20 have the same structure, and even the first building block component 10 and the second building block component 20 have the same structure, that is, the first building block component 10 and the second building block component 20 can be standard parts and can be replaced with each other, without any special changes or designs to the building block components or the male and female heads.

[0040] Figure 3b and 3cSchematic cross-sectional structural diagrams of a functional building block 100 according to a third embodiment of the present invention are shown in two states. Figure 3b The schematic diagram of the building block 100 is shown in a state where the first building block 10 and the second building block 20 are not plugged in, wherein the connection line (in Figure 3b One end of the LED lamp 2 (left side in the figure) is connected to the negative pole of the left battery 1, and the other end is connected to one end of the LED lamp 2 (in the figure). Figure 3b The other end of LED lamp 2 (on the left side) is connected; Figure 3b The right end in the middle) and the switch element 4 (at Figure 3b The switch element 4 is connected to one end (upper end) of the right side battery 1, and the other end (lower end) of the switch element 4 is configured as a free contact spring end and remains out of contact with other electrical components, especially the positive pole of the right battery 1 in the battery 1, so that the internal circuit of the light emitting lamp 30 remains disconnected as a whole, and the LED lamp 2 is in an inactive state and does not emit light. Among them, the negative pole of the right battery 1 is exposed to the side of the light emitting lamp 30 as a whole, and the free spring end corresponds to the positive pole position of the right battery 1.

[0041] like Figure 3c As shown, when the first building block 10 is inserted into the second building block 20 from the bottom and the two building blocks are inserted into each other, the top of the second building block 20 is pressed so that Figure 2b The free contact spring end is deflected inward and contacts the left battery 1 (corresponding to the attached Figure 3b The positive electrode of the right battery 1 in the power source 1 is contacted, so that the internal circuit of the functional component 30 is closed, so that the LED lamp 2 is activated and emits light. Of course, in other embodiments, the positive and negative electrode installation directions of the power source 1 can be replaced.

[0042] In addition, by Figure 3c It can be seen that there is an opening at the connection between the male head of the first building block component 10 and its main body, and the functional element 2, that is, the LED lamp 2 installed on the bracket 3, penetrates the opening and protrudes into the male head, and the light of the LED lamp 2 can also be transmitted to the outside of the first building block component 10 through the opening. When the male head of the first building block component 10 is plugged into another transparent or light-transmissive third building block component, the light of the LED lamp 2 can also be radiated through the third building block component. Of course, the first building block component 10 itself can also be transparent, and the light of the LED lamp 2 can be radiated through the first building block component 10. Furthermore, the LED lamp 2 that penetrates the above-mentioned opening and protrudes into the male head does not exceed the end of the male head opposite to the main body of the first building block component 10, which, on the one hand, plays a role in protecting the LED lamp 2, and on the other hand, does not affect the plugging of the male head of the first building block component 10 with another building block component.

[0043] It is also conceivable that the functional component can be configured as other types of functional components, such as a speaker, a music player module, etc. Thus, when the first building block component and the second building block component are not plugged into each other, the corresponding speaker, music player module, etc. are in an inactive state and do not perform the corresponding function; on the contrary, when the first building block component and the second building block component are plugged into each other, the corresponding speaker, music player module reaches an activated state and starts to perform the corresponding function, such as emitting a sound or playing the corresponding music, and so on.

It should be understood that the features disclosed in the above embodiments, except where otherwise specified, can be used alone or in combination.
