Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0064] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0065] In the following description, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0067] This application provides a heating structure that can be applied to a smart in-vehicle massage device, enabling the smart in-vehicle massage device to have a heating function.

[0068] Figure 1a This is a schematic diagram of a partitioned heating layer in a heating structure provided in an embodiment of this application. Figure 1b This is a schematic diagram illustrating the distribution of multiple heating layers in a heating structure provided in an embodiment of this application. For example... Figure 1a and Figure 1b As shown, the heating structure includes:

[0069] Zoned heating layer 103;

[0070] The partitioned heating layer 103 has at least two heating zones. Figure 1a (A, B, and C);

[0071] At least two of the heating regions are sequentially distributed along the same side of the partitioned heating layer 103;

[0072] The heating voltages for different heating zones are different.

[0073] In this embodiment, the partitioned heating layer includes a side edge disposed along a first direction and a side edge disposed along a second direction. The partitioned heating layer can be divided along the side edge disposed along the first direction to obtain at least two heating regions, thereby achieving that at least two heating regions are sequentially distributed along the side edge disposed along the first direction.

[0074] Of course, the partitioned heating layer can also be divided into at least two heating areas along the side set in the second direction, thereby realizing that at least two heating areas are distributed sequentially along the side set in the second direction.

[0075] Here, the first direction is different from the second direction. The first direction can be the extension direction of one of the two adjacent sides in the partitioned heating layer, and the second direction can be the extension direction of the other of the two adjacent sides in the partitioned heating layer.

[0076] It should be noted that multiple heating zones can be set up to have the same area but different resistance values.

[0077] For example, in the process of dividing the heating area into three equal heating regions, if the input voltage includes 5V, 9V and 12V, then by using the resistance ratio equal to the square ratio of the input voltage, the resistance ratios of the three heating regions can be calculated to be 25, 81 and 144. Therefore, the resistance value of the first heating region can be designed as (25 / 144)*R, the resistance value of the second heating region can be designed as ((81-25) / 144)*R, and the resistance value of the third heating region can be designed as ((144-81) / 144)*R.

[0078] Of course, different heating zones can also be obtained by dividing the heating layer into zones based on the input voltage.

[0079] Here, the heating wires laid in the partitioned heating layer have the same internal resistance per unit area. When partitioning, the area and total resistance of the partitioned heating layer can be determined first.

[0080] For example, the input voltage includes 5V, 9V, and 12V. The partitioned heating layer is divided into three heating zones. If the area and total resistance of the partitioned heating layer are both divided into 5V / 12V zones, then the first heating zone can be designed to have a ratio of 5 / 12, the second heating zone to have a ratio of (9-5) / 12, and the third heating zone to have a ratio of (12-9) / 12.

[0081] Each heating zone in the aforementioned partitioned heating layer corresponds to a heating voltage, and different heating zones correspond to different heating voltages. In other words, the partitioned heating layer does not correspond to a single heating voltage, but rather achieves multiple heating voltages by dividing the space into multiple heating zones. This allows the heating structure to be heated under different heating voltages. Furthermore, it allows for flexible selection of heating zones with different heating voltages, further enriching the heating methods of the heating structure.

[0082] For example, such as Figure 1a and 1b As shown, the partitioned heating layer is divided into a first heating area A, a second heating area B, and a third heating area C. The heating voltage V3 corresponding to the first heating area A is 5V, the heating voltage V4 corresponding to the second heating area B is 9V, and the heating voltage V5 corresponding to the third heating area C is 12V. In this way, the partitioned heating layer can be heated under three different heating voltages: 5V, 9V, and 12V.

[0083] For example, the partitioned heating layer can be divided into two heating zones, namely the first heating zone A and the second heating zone B. In this way, the partitioned heating layer can be heated under the action of two different heating voltages.

[0084] For example, the partitioned heating layer can be heated by two different heating voltages: 5V and 9V. Or, for another example, the partitioned heating layer can be heated by two different heating voltages: 9V and 12V.

[0085] In this embodiment, the heating structure may include one or more partitioned heating layers. When there are multiple partitioned heating layers, the number of heating areas in different partitioned heating layers may be the same or different; this embodiment does not impose any limitations on this.

[0086] It is understood that in the embodiments of this application, the heating structure includes a partitioned heating layer, and the heating voltage corresponding to different heating areas in the partitioned heating layer is different. That is to say, the heating structure can heat under different heating voltages, thus realizing that the heating structure can be applied to different heating voltages and expanding the applicable scenarios of the heating structure.

[0087] For example, the heating structure can be matched with the onboard power supplies of different car models, enabling it to heat normally under the power supply of various car models. This means that the intelligent in-vehicle massage device with this heating structure can be used normally in different car models.

[0088] Furthermore, the heating structure heats different heating zones, making the heating method more flexible and improving the heating effect.

[0089] In some embodiments, such as Figure 1a and Figure 1b As shown, the heating structure further includes at least one single-zone heating layer 100;

[0090] Each of the single-zone heating layers 100 is stacked with the partition heating layers 103;

[0091] Each of the single-zone heating layers 100 corresponds to a heating voltage, and different single-zone heating layers 100 correspond to different heating voltages;

[0092] The heating voltage of the single-zone heating layer 100 is at least partially the same as that of the partitioned heating layer 103.

[0093] In this embodiment, each single-zone heating layer and the partition heating layer are stacked, thereby realizing that the heating structure is composed of multiple stacked heating layers. Among the multiple stacked heating layers, the dimensions of the multiple heating layers can all be the same, and when stacked, the upper heating layer can cover the lower heating layer in adjacent heating layers;

[0094] Of course, the dimensions of the multiple heating layers can be different. When multiple heating layers are stacked, the centers of two adjacent heating layers can be aligned.

[0095] It should be noted that each heating layer may be provided with heating components, and the heating layer can be heated by the heating components. The heating components may include heating wires, etc., and the embodiments of this application do not limit this.

[0096] In this embodiment, the single-zone heating layer has one heating area, which is different from the partitioned heating layer which has multiple heating areas. When there are multiple single-zone heating layers, the heating voltage corresponding to each single-zone heating layer is different.

[0097] For example, such as Figure 1b As shown, in at least two single-zone heating layers, the heating voltage corresponding to one single-zone heating layer is V1, and the heating voltage corresponding to the other single-zone heating layer is V2, and V1 and V2 are different.

[0098] In this embodiment, the number of single-zone heating layers and the number of heating zones in the partitioned heating layers can be set according to actual needs. For example, Figure 2 As shown, a single-zone heating layer can be set to two, namely a first heating layer 101 and a second heating layer 102; a partitioned heating layer can be set to three heating areas, namely a first heating area A, a second heating area B and a third heating area C.

[0099] For example, in Figure 2The number of single-zone heating layers can be increased, or the number of heating areas in the partitioned heating layer can be increased. This application does not limit this.

[0100] In this embodiment, at least a portion of the heating voltage in the single-zone heating layer and the partitioned heating layer is the same, which may include: the heating voltage in the single-zone heating layer and the partitioned heating layer is the same.

[0101] For example, such as Figure 2 As shown, the single-zone heating layer of the heating structure includes a first heating layer A and a second heating layer B; the heating voltage V1 corresponding to the first heating layer is 5V; the heating voltage V2 corresponding to the second heating layer is 9V; as shown... Figure 1a and 1b As shown, the partitioned heating layer includes multiple heating areas: a first heating area A, a second heating area B, and a third heating area C. The heating voltage V3 corresponding to the first heating area A is 5V, the heating voltage V4 corresponding to the second heating area B is 9V, and the heating voltage V5 corresponding to the third heating area C is 12V. This achieves two identical heating voltages in both the single-zone heating layer and the partitioned heating layer: a 5V heating voltage and a 9V heating voltage, respectively.

[0102] Of course, the heating voltage of at least some parts of the single-zone heating layer and the partitioned heating layer are the same, and may also include: the heating voltage of all parts of the single-zone heating layer and the partitioned heating layer are the same.

[0103] For example, the heating structure includes three single-zone heating layers corresponding to three different heating voltages, which are the same as the three different heating voltages corresponding to the three heating areas of the partitioned heating layer.

[0104] In this embodiment, the heating structure may be formed by multiple heating layers stacked together. The heating structure may be sheet-like or block-like, and this embodiment does not limit this.

[0105] It is understood that in the embodiments of this application, the heating structure provides heating methods that can be applied to different heating voltages for different single-zone heating layers, and also provides heating methods that can be applied to different heating voltages for different heating areas in the partitioned heating layer. This not only expands the applicable scenarios of the heating structure, but also makes the heating method of the heating structure more flexible and improves the heating effect of the heating structure.

[0106] Furthermore, since at least some heating voltages are the same in single-zone heating layers and partitioned heating layers, it is possible to select a more suitable heating method when the heating voltage is the same, thereby further improving the heating effect of the heating structure.

[0107] In some embodiments, such as Figure 2As shown, the partitioned heating layer 103 includes: a first heating region A, a second heating region B, and a third heating region C, wherein the second heating region B is located between the first heating region A and the third heating region C;

[0108] At least one of the single-zone heating layers includes a first heating layer 101 and a second heating layer 102;

[0109] The heating voltage corresponding to the first heating region A is the same as the heating voltage corresponding to the first heating layer 101;

[0110] The heating voltage corresponding to the second heating region B is the same as the heating voltage corresponding to the second heating layer 102;

[0111] The heating voltage corresponding to the first heating region A and the heating voltage corresponding to the second heating region B are both different from the heating voltage corresponding to the third heating region C.

[0112] In this embodiment, the first heating layer, the second heating layer, and the partitioned heating layer are all stacked. The order in which these three heating layers are stacked can be set according to actual conditions, and this embodiment does not limit this.

[0113] For example, such as Figure 2 As shown, a second heating layer 102 can be stacked between the first heating layer 101 and the partitioned heating layer 103.

[0114] In this embodiment, the heating voltage corresponding to the first heating region and the heating voltage corresponding to the first heating layer can both be a first voltage. The heating voltage corresponding to the second heating region and the heating voltage corresponding to the second heating layer can both be a second voltage. The heating voltage corresponding to the third heating region is a third voltage.

[0115] Here, the first voltage can be set to be less than the second voltage, and the second voltage can be set to be less than the third voltage.

[0116] For example, the first voltage can be set to 5V, the second voltage can be set to 9V, and the third voltage can be set to 12V.

[0117] In this embodiment, a first voltage may be provided for heating a first heating region or a first heating layer; a second voltage may be provided for heating a second heating region or a second heating layer; and a third voltage may be provided for a third heating region.

[0118] It is understood that, in this embodiment of the application, by setting three heating areas in the partitioned heating layer, heating can be achieved for the third heating area with different heating voltages, as well as for the first and second heating areas with the same heating voltages, which simplifies the design while making the heating method more flexible.

[0119] In some embodiments, such as Figure 2 As shown, the partitioned heating layer 103 has a common positive terminal C+ and multiple negative terminals;

[0120] Each heating region in the partitioned heating layer 103 is provided with a negative terminal, and the negative terminals of different heating regions are different.

[0121] The common positive pole is used to connect with different negative poles.

[0122] In this embodiment, the number of heating zones in the partitioned heating layer is the same as the number of negative terminals, and each negative terminal can be connected to the common positive terminal to form a loop, so as to achieve heating of at least one heating zone.

[0123] The aforementioned common positive electrode can be placed in any heating area, and this application embodiment does not impose any restrictions.

[0124] Here, as Figure 2 As shown, the partitioned heating layer 103 may include a first heating region A, a second heating region B and a third heating region C. The first heating region A is provided with a first negative terminal C1-, the second heating region B is provided with a second negative terminal C2-, and the third heating region C is provided with a third negative terminal C3-.

[0125] like Figure 2 As shown, the four wires that can be pulled out from the partitioned heating layer are: the first wire L+ connected to the common positive terminal C+, the second wire L1- connected to the first negative terminal C1-, the third wire L2- connected to the second negative terminal C2-, and the fourth wire L2- connected to the third negative terminal C3-.

[0126] The heating voltages corresponding to the first negative terminal of the first heating region, the second negative terminal of the second heating region, and the third negative terminal of the third heating region are all different. For example, the heating voltage corresponding to the first negative terminal of the first heating region is -5V, the heating voltage corresponding to the second negative terminal of the second heating region is -9V, and the heating voltage corresponding to the third negative terminal of the third heating region is -12V.

[0127] It is understood that, in this embodiment of the application, by setting a common positive terminal that can be connected to different negative terminals, the number of positive terminals set in the partitioned heating layer and the number of wires connecting the positive terminals can be reduced, which not only simplifies the design of the heating structure, but also reduces the space occupied by the heating structure.

[0128] In some embodiments, such as Figure 2 As shown, the common positive terminal C+ is connected to the first negative terminal C1- of the first heating region A in the partitioned heating layer 103, and the first heating region A is in a heating state;

[0129] or,

[0130] The common positive terminal C+ is connected to the second negative terminal C2- of the second heating region B in the partitioned heating layer 103, and both the first heating region A and the second heating region B are in a heating state.

[0131] or,

[0132] The common positive terminal C+ is connected to the third negative terminal C3- of the third heating region C in the partitioned heating layer 103, and the first heating region A, the second heating region B and the third heating region C are all in a heating state.

[0133] The first heating region mentioned above is in a heating state, indicating that the first heating region is being heated.

[0134] The fact that the first heating region and the second heating region are in a heating state indicates that both the first heating region and the second heating region are being heated.

[0135] The first heating area, the second heating area, and the third heating area are all in a heating state, indicating that the first heating area, the second heating area, and the third heating area are all being heated, that is, the entire area of ​​the partitioned heating layer is being heated.

[0136] It is understood that, in the embodiments of this application, by setting a common positive terminal and connecting different negative terminals, heating at least one heating area of ​​the third heating layer can be achieved, thereby making the heating of the partitioned heating layer more flexible.

[0137] In some embodiments, the positive ends of the plurality of heating layers are electrically connected to the same conductor through connection holes.

[0138] It is understood that in the embodiments of this application, the positive terminals of multiple heating layers are electrically connected to the same wire through connection holes, so that multiple heating layers can share a single wire, and it is not necessary to set a positive wire for each heating layer, which can reduce the number of wires in the heating structure.

[0139] In some embodiments, the wires connected to each of the single-zone heating layers are spaced apart on the first side of the heating structure;

[0140] And / or,

[0141] The wires connecting each heating region in the partitioned heating layer are all spaced apart on the second side of the heating structure, which is different from the first side.

[0142] In this embodiment, each single-zone heating layer is connected by two wires, which are connected by two power supply wires to achieve heating of the corresponding single-zone heating layer.

[0143] It should be noted that, as Figure 2 As shown, the first heating layer 101 can be extended with two wires, namely the first positive wire L4+ and the first negative wire L4-. The second heating layer 102 can also be extended with two wires, namely the second positive wire L5+ and the second negative wire L5-.

[0144] When the first positive electrode wire L4+ and the first negative electrode wire L4- are connected, the first heating layer 101 is heated. When the second positive electrode wire L5+ and the second negative electrode wire L5- are connected, the second heating layer is heated.

[0145] Here, the two wires of the first heating layer and the two wires of the second heating layer are distributed at intervals on the first side of the heating structure.

[0146] In this embodiment, the wires connecting each heating region in the partitioned heating layer are all spaced apart on the second side of the heating structure.

[0147] Here, a common positive end and three negative ends of the partitioned heating layer can be evenly distributed on the second side of the heating structure.

[0148] Of course, the partitioned heating layer may not have a common positive terminal. Instead, each heating area can have two power supply wires, namely the third positive wire and the third negative wire. In this way, the third positive wire and the third negative wire of each heating area can be distributed at intervals on the second side of the heating structure in the layout of the wires connecting the partitioned heating layer.

[0149] In this embodiment, the wires spaced apart on the first side of the heating structure and the wires spaced apart on the second side of the heating structure are staggered to reduce the possibility of short circuits in the wires.

[0150] The first side and the second side mentioned above can be adjacent sides of the heating structure or opposite sides of the heating structure. This application does not limit this.

[0151] It is understood that, in the embodiments of this application, by separately setting the wires of the single-zone heating layer and the wires of the partitioned heating layer on different sides of the heating structure, the wire layout of the heating structure can be made more reasonable.

[0152] This application also proposes a heating device. For example... Figure 3 As shown, the heating device includes:

[0153] Heating structure 10 as described in one or more of the above embodiments;

[0154] The power supply terminal 20 is used to transmit input voltage to the heating structure 10;

[0155] The control circuit 30 is electrically connected to the power supply terminal 20 and the heating structure 10 respectively, and is used to control the heating structure 10 to heat based on the input voltage.

[0156] In the embodiments of this application, such as Figure 3 As shown, the power supply terminal 20 of the heating device can be electrically connected to the plugged-in power supply 40 to transmit the input voltage. Here, the plugged-in power supply is different for different usage scenarios, which may result in different input voltages at the power supply terminal.

[0157] For example, in automotive applications, the power supply terminal can be electrically connected to the on-board power supplies of different vehicle models, allowing the power supply terminal to have different input voltages. That is, the on-board power supply of vehicle model X1 causes the power supply terminal to transmit an input voltage that is different from the on-board power supply of vehicle model X2.

[0158] It should be noted that the input voltage at the power supply terminal of the heating device may include 5V, 9V, or 12V.

[0159] In this embodiment, the control circuit is used to control the heating structure to heat based on the input voltage. Controlling the heating structure to heat may include controlling the heating of a single-zone heating layer within the heating structure, or controlling the heating of at least one heating area within a partitioned heating layer.

[0160] It is understood that the control circuit in this embodiment is electrically connected to both the power supply and the heating structure, and is used to control the heating structure to heat based on the input voltage. That is, based on different input voltages, it can control the heating of single-zone heating layers with different heating voltages, and it can also control the heating of heating areas with different heating voltages. Thus, the heating control can be adapted to varying input voltages, which not only improves the heating effect and enhances the user experience, but also expands the applicable scenarios of the heating device.

[0161] In some embodiments, the heating device includes a plurality of drive circuits electrically connected to the control circuit;

[0162] The driving circuit is electrically connected to the heating structure, and different driving circuits are used to provide different heating voltages to the heating structure.

[0163] In this embodiment, different driving circuits provide different heating voltages. The control circuit can select different driving circuits for heating based on the input voltage at the power supply terminal.

[0164] The aforementioned driving circuit may include: an N-channel metal-oxide-semiconductor (NMOS) switch driving circuit, a P-channel metal-oxide-semiconductor (PMOS) switch driving circuit, a load switch driving circuit, and a DC-DC power supply control circuit, etc., and the embodiments of this application do not limit this.

[0165] It is understood that, in the embodiments of this application, by setting multiple driving circuits and providing different heating voltages to the heating structure, the heating structure can be better heated based on the provided heating voltage.

[0166] In some embodiments, such as Figure 5 , Figure 6 and Figure 7 As shown, the heating device includes:

[0167] The first driving circuit 50 is electrically connected to the control circuit, the first heating layer and the first heating area of ​​the heating structure, and is used to drive the first heating layer or the first heating area to heat.

[0168] The second driving circuit 60 is electrically connected to the control circuit, the second heating layer and the second heating area of ​​the heating structure, and is used to drive the second heating layer or the second heating area to heat.

[0169] The third driving circuit 70 is electrically connected to the control circuit and the third heating area of ​​the heating structure, and is used to drive the heating area to heat.

[0170] like Figure 4 and Figure 5 As shown, the control circuit 30 has a first control pin PB1, which is electrically connected to the input pin 51 of the first drive circuit 50, and the output pin 52 of the first drive circuit 50 is electrically connected to the first heating layer and the first heating area of ​​the heating structure.

[0171] like Figure 4 and Figure 6 As shown, the control circuit 30 also has a second control pin PA2, which is electrically connected to the input pin 61 of the second drive circuit 60, and the output pin 62 of the second drive circuit 60 is electrically connected to the second heating layer and the second heating area.

[0172] like Figure 4 and Figure 7 As shown, the control circuit 30 also has a third control pin PA4, which is electrically connected to the input pin 71 of the third drive circuit 70, and the output pin 72 of the third drive circuit 70 is electrically connected to the third heating area.

[0173] In this embodiment, the heating structure includes a first heating layer, a second heating layer, and a partitioned heating layer having a first heating region, a second heating region, and a third heating region.

[0174] Here, the heating voltage of the first heating layer and the heating voltage of the first heating region are the same, and thus they can be connected together to the first driving circuit. That is, the first driving circuit can provide voltages within a first voltage range to the first heating layer and the first heating region respectively, so that the first heating layer or the first heating region is heated.

[0175] Similarly, the heating voltage of the second heating layer is the same as that of the partitioned heating layer, and therefore they can be connected together to the second driving circuit. That is, the second driving circuit can provide voltages within the second voltage range to the second heating layer and the second heating region respectively, so that the second heating layer can be heated, and both the first heating region and the second heating region can be heated.

[0176] The third driving circuit can provide a voltage within the third voltage range to the third heating region, so that the first heating region, the second heating region, and the third heating region are all heated.

[0177] It is understood that the embodiments of this application provide heating voltage to the heating structure by setting three driving circuits, which enables more precise heating control of the heating structure.

[0178] In some embodiments, such as Figure 3 and Figure 8 As shown, the heating device further includes:

[0179] The detection circuit 80 includes a signal terminal 81 and an output terminal 82. The signal terminal 81 is electrically connected to the power supply terminal 20, and the output terminal 82 is electrically connected to the control circuit 30. The detection circuit 80 is used to send the detected input voltage to the control circuit 30.

[0180] or,

[0181] The control circuit has a communication pin that is electrically connected to the power supply terminal. The control circuit is used to identify the input voltage transmitted by the power supply terminal.

[0182] In this embodiment of the application, the heating device may further include an interface module and a power management integrated circuit. The interface module may be electrically connected to the power supply and the power management integrated circuit respectively, and is used to transmit the input voltage provided by the power supply to the power management integrated circuit.

[0183] The interface module 91 may include Figure 9 The 24-pin Type-C interface is shown. The power management integrated circuit 92 may include... Figure 10 The integrated circuit shown has 6 pins.

[0184] It should be noted that, Figure 8 The detection circuit 80 shown needs to be matched with the power management integrated circuit 92 to detect the input voltage at the power supply terminal.

[0185] in, Figure 8 The detection circuit 80 shown can be composed of two detection inductors and a detection capacitor. The output terminal 82 of the detection circuit can be connected to the control circuit to send the detection result to the control circuit.

[0186] Of course, this application embodiment also provides a control circuit that directly obtains the input voltage through a communication pin.

[0187] For example, the control circuit uses I 2 The SCL and SDA pins of C communicate with the power management integrated circuit to directly obtain the input voltage.

[0188] This application also proposes an intelligent in-vehicle massage device, which includes:

[0189] Equipment body;

[0192] In this embodiment, the intelligent in-vehicle massage device may include an in-vehicle lumbar massage pillow, and the corresponding device body may include the lumbar pillow body. Of course, the intelligent in-vehicle massage device can also be used on other parts of the human body, such as the head or shoulders, and this embodiment does not limit this.

[0193] The aforementioned partitioned heating layer is designed for situations with low heating power. Therefore, placing the partitioned heating layer close to the heating surface of the device body can reduce energy loss.

[0194] It is understood that the embodiments of this application include a heating structure or heating device, which enables the heating control of the heating device to be adapted to varying input voltages, thereby not only improving the heating effect and enhancing the user experience, but also expanding the applicable scenarios of the heating device.
