DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0048] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0050] In the description of the present utility model, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when used. It is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.

[0051] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0052] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0053] The application scenario of this embodiment is described below:

[0054] In electrical devices, such as flashlights, remote controls, digital cameras, electronic clocks, wireless mice, stereos, tape players, game consoles, radios, electric fans, telephones, computers, doorbells, wireless mice, wireless keyboards, watches, alarm clocks, computers, televisions, gas stoves, gas water heaters, remote-controlled cars, remote-controlled airplanes, etc., battery boxes are required for power supply, and the batteries in the battery boxes are used to provide electrical energy.

[0055] In the prior art, oxidation easily occurs at the contact point between the conductive sheet and the battery in the battery box, resulting in poor contact between the battery and the conductive sheet, affecting the conductive performance. The oxidation at the contact point between the conductive sheet and the battery here can be understood as the appearance of oxidation areas at the positive and negative poles of the battery, or the appearance of oxidation areas on the conductive sheet, or the appearance of oxidation areas at the positive and negative poles of the battery and oxidation areas on the conductive sheet.

[0056] Researchers found that there is only one contact point between the battery and the conductive sheet in the battery box in the prior art, which is equivalent to a single point of contact. During the double 85 aging test, the contact point between the battery and the conductive sheet is easily oxidized, affecting the conductivity between the battery and the conductive sheet. In particular, when the battery box is subjected to vibration, the contact between the battery and the conductive sheet is poor, which greatly affects the conductivity between the battery and the conductive sheet.

[0057] Among them, the double 85 aging test can be understood as a reliability test of the experimental samples under the condition that the temperature of the experimental box is set at 85℃ and the humidity is 85%. The "double 85 aging test" experiment is also a more rigorous reliability test experiment. To compare the aging and some characteristic changes of the product before and after the "double 85 aging test", and then improve the product according to these changes and shortcomings.

[0058] In view of this, please refer to Figure 1-Figure 10 The battery conductive sheet 1000, battery box and power-consuming device provided in the embodiment of the utility model can solve this problem, which will be described in detail below.

[0059] Please refer to Figure 1-Figure 4 In an embodiment of the utility model, an electrical device is provided. In this embodiment, the electrical device may be an electric meter. Of course, in other embodiments, the electrical device may also be understood as other devices that require battery power, such as electric toys, flashlights, remote controls, digital cameras, electronic clocks, wireless mice, speakers, etc.

[0060] The electrical device includes a battery box and an electrical unit. The electrical unit may be, for example, a sensor, a display, a circuit board, etc. The battery box may be connected to the electrical unit. The battery box may contain batteries, which are used to provide electrical energy to the electrical unit.

[0061] The battery box includes a box body 2100 and a battery conductive sheet 1000, wherein the conductive body 100 (described in detail below) of the battery conductive sheet 1000 is arranged in the box body 2100, and the box body 2100 is used to accommodate the battery 10, wherein the battery conductive sheet 1000 can ensure good conductivity between the battery 10 in the battery box and the battery conductive sheet 1000.

[0062] Specifically, in this embodiment, the box body 2100 includes a battery accommodating box 2110 and a cover body 2220, wherein the battery accommodating box 2110 is used to accommodate the battery 10, and the cover body 2220 can be covered on the battery accommodating box 2110 to cover the battery 10, and the battery accommodating box 2110 and the cover body 2220 can be connected by a snap structure to facilitate the disassembly or installation between the battery accommodating box 2110 and the cover body 2220.

[0063] The battery 10 has a positive electrode and a negative electrode, and the positive electrode and the negative electrode are located on the same side of the battery 10. In order to facilitate the battery 10 to output electrical energy to the outside, in this embodiment, the number of battery conductive sheets 1000 in the box body 2100 is two.

[0064] The multi-contact conductor 200 of one of the battery conductive sheets 1000 is used to cooperate with the positive electrode of the battery 10 , and the multi-contact conductor 200 of the other battery conductive sheet 1000 is used to cooperate with the negative electrode of the battery 10 .

[0065] Specifically, the battery conductive sheet 1000 includes a conductive body 100 and a multi-contact conductor 200. The multi-contact conductor 200 is connected to the conductive body 100. A plurality of contact portions 201 distributed at intervals are formed on the multi-contact conductor 200. At least two of the plurality of contact portions 201 are used to simultaneously make electrical contact with the positive or negative pole of the battery 10. The conductive body 100 is installed in a box body 2100 for transmitting the electrical energy of the battery to the power-consuming unit.

[0066] Since the battery conductive sheet 1000 has multiple contact portions 201 for contacting the battery 10, it can be ensured that at least two of the contact portions 201 are in electrical contact with the positive or negative electrode of the battery 10 at the same time. Even if one of the contact positions is oxidized, normal conduction between the battery 10 and the battery conductive sheet 1000 can still be ensured, ensuring good conductivity between the battery 10 and the conductive sheet of the battery box. Preferably, all the contact portions 201 are used to contact the positive or negative electrode of the battery.

[0067] It is easy to understand that the battery conductive sheet 1000 has multiple contact parts 201, and the multiple contact parts 201 can contact the positive or negative pole of the battery 10 at the same time. Even if one of the contact positions (the position where the contact part 201 contacts the positive or negative pole of the battery 10) is oxidized, the remaining contact positions that have not been oxidized can still ensure normal conduction between the battery 10 and the battery conductive sheet 1000, and ultimately ensure the normal operation of the electrical device.

[0068] Please continue to refer to Figure 5-Figure 10 The multi-contact conductor 200 includes a plurality of conductive strips 210 , which are connected to the conductive body 100 , and each conductive strip 210 is provided with at least one contact portion 201 .

[0069] It should be noted that the “plurality” here can be understood as at least two. In the present embodiment, each multi-contact conductor 200 includes four conductive strips 210 , and each conductive strip 210 is provided with a contact portion 201 .

[0070] Of course, in other embodiments, each multi-contact conductor 200 may include two conductive strips 210, three conductive strips 210, five conductive strips 210, etc. The number of conductive strips 210 is not limited here. At the same time, each conductive strip 210 may also be distributed with two contact parts 201, three contact parts 201 or four contact parts 201, etc.

[0071] Specifically, in this embodiment, the four conductive strips 210 are distributed in sequence at intervals, that is, the contact portions 201 on two adjacent conductive strips 210 are separated by the through slots 202, and the intervals between two adjacent conductive strips 210 among the four conductive strips 210 are equal.

[0072] Among them, the contact parts 201 of four conductive strips 210 can contact the positive or negative pole of the battery 10 at the same time. Of course, in some cases, the contact parts 201 of three conductive strips 210 can contact the positive or negative pole of the battery 10 at the same time, or the contact parts 201 of two conductive strips 210 can contact the positive or negative pole of the battery 10 at the same time.

[0073] In order to facilitate the output of the electric energy of the battery 10 through multiple conductive strips 210, in this embodiment, the multi-contact conductor 200 also includes a collecting plate 220, which is connected to the conductive body 100. The heads of the four conductive strips 210 are all connected to the collecting plate 220, and the through grooves 202 are arranged to penetrate from the head to the tail of the conductive strip 210, so that the tails of the multiple conductive strips 210 are spaced apart.

[0074] In this embodiment, the collecting plate 220 includes a flat plate 221 and an arc plate 222, one side edge of the flat plate 221 is connected to four conductive strips 210 at the same time, the other side edge of the flat plate 221 is connected to one side edge of the arc plate 222, and the other side edge of the arc plate 222 is connected to the conductive body 100. It should be noted that the arc plate 222 is used to make the flat plate 221 distributed at an angle relative to the conductive body 100, and the angle can be an acute angle.

[0075] In this embodiment, the conductive body 100 is a strip-shaped plate, and the arc-shaped plate 222 is connected to the middle position of one side edge of the conductive body 100 .

[0076] Among them, the conductive strip 210 includes a first flat strip 211 and a bent strip 212. One end of the first flat strip 211 is connected to the conductive body 100. Specifically, one end of the first flat strip 211 is connected to the edge of the flat plate 221 of the collecting plate 220, and the other end of the first flat strip 211 is connected to the bent strip 212. The outer convex surface of the bent strip 212 forms the contact portion 201.

[0077] It is easy to understand that Figure 2 As shown, since the positive and negative electrodes of the battery 10 are both groove structures, the outer convex surface of the bent strip 212 can easily contact the positive and negative electrodes of the battery 10.

[0078] Please continue to refer to Figure 6 The conductive strip 210 further includes a second flat strip 213 , one end of the second flat strip 213 is connected to an end of the curved strip 212 away from the first flat strip 211 , the second flat strip 213 is distributed at an angle with the first flat strip 211 , and extends toward the conductive body 100 .

[0079] In addition, in this embodiment, the conductive strip 210 further includes a support block 214, which is connected to one end of the second flat strip 213 away from the curved strip 212, and is used to increase the contact area between the conductive strip 210 and the reset member 300 when the conductive strip 210 abuts against the surface of the reset member 300 (described in detail below). The connection between the support block 214 and the second flat strip 213 is an arc transition toward one side of the conductive body 100.

[0080] In order to facilitate the reset of the conductive strip 210 when the battery 10 is taken out of the box body 2100 , when the battery 10 is installed in the box body 2100 , it is ensured that the contact portion 201 of the conductive strip 210 can stably contact the positive or negative electrode of the battery 10 .

[0081] In this embodiment, the battery conductive sheet 1000 further includes a reset member 300, and the reset member 300 is connected to the conductive body 100 and / or the multi-contact conductive body 200. In this embodiment, the reset member 300 is connected to the conductive body 100.

[0082] Of course, in other embodiments, the reset member 300 may also be connected to the conductive strip 210 of the multi-contact conductor 200 , or the reset member 300 may be connected to the conductive body 100 and the conductive strip 210 of the multi-contact conductor 200 at the same time.

[0083] The plurality of contact portions 201 are used to move toward the conductive body 100 when the battery 10 is assembled into the battery receiving box 2110 of the box body 2100 , and to move away from the conductive body 100 under the action of the reset member 300 when the battery 10 is disassembled.

[0084] The reset member 300 is disposed between the conductive body 100 and the conductive strip 210 , and the reset member 300 may be a spring sheet or a spring.

[0085] In this embodiment, specific reference is made to Figure 6 and Figure 7 The reset member 300 includes a connecting plate 310, an arc-shaped deformable plate 320 and a support plate 330 connected in sequence. The connecting plate 310 is connected to the conductive body 100. The support plate 330 is used to support and reset the conductive bar 210 under the deformation of the arc-shaped deformable plate 320 during the disassembly process of the battery 10.

[0086] Specifically, under the deformation effect of the arc-shaped deformation plate 320 , the surface of the support plate 330 is used to support the support block 214 of the conductive bar 210 .

[0087] In addition, the reset member 300 further includes an abutment plate 340 , which is connected to one end of the support plate 330 away from the arc-shaped deformation plate 320 . The abutment plate 340 is used to move toward the conductive body 100 to abut against the conductive body 100 during the assembly of the battery 10 .

[0088] Among them, it should be noted that during the process of assembling the battery 10 into the battery housing box 2110 of the box body 2100, the arc-shaped deformable plate 320 undergoes elastic deformation and at the same time will feedback elastic force to the operator who assembles the battery 10. Generally speaking, when the battery 10 is correctly installed, for example, when the positive and negative poles of the battery 10 are aligned with the multi-contact conductor 200, since part of the structure of the multi-contact conductor 200 (such as the bent bar 212) will extend into the groove 11 of the battery 10, the arc-shaped deformable plate 320 undergoes a smaller amount of elastic deformation, and the elastic feedback to the operator who assembles the battery 10 is smaller.

[0089] If the battery 10 is incorrectly installed, for example, when the other side of the battery 10 opposite to the positive and negative poles is aligned with the multi-contact conductor 200, since some structures of the multi-contact conductor 200 (such as the bent bar 212) will not extend into the groove 11 of the battery 10, the arc-shaped deformation plate 320 will undergo a large elastic deformation, and the operator who assembles the battery 10 will be given a large elastic feedback. As a result, it can be known that the battery 10 is installed in the wrong direction, and the operator is reminded to reinstall the battery 10 correctly.

[0090] It should be noted that, in this embodiment, the support plate 330 is deformable. Specifically, the support plate 330 is used to, during the assembly process of the battery 10, when the contact portion 201 is subjected to the first preset force, the support block 214 of the conductive strip 210 abuts against the support plate 330, so that the support plate 330 moves toward the conductive body 100 by a first preset distance, wherein the force direction of the contact portion 201 can refer to Figure 7 The direction of the arrow.

[0091] Afterwards, during the process of continuing to assemble the battery 10, the support plate 330 is used to move the support plate 330 toward the conductive body 100 by a second preset distance under the action of the second preset force on the contact portion 201. At this time, the abutment plate 340 abuts against the conductive body 100. At this time, the battery 10 can be just loaded into the box body 2100, which can be understood as the battery 10 is correctly installed, or, between the abutment plate 340 and the conductive body 100 abutting, the battery 10 is just loaded into the box body 2100, which can also be understood as the battery 10 is correctly installed.

[0092] In addition, the support plate 330 is used to cause the support block 214 of the conductive strip 210 to abut against the support plate 330 when the contact portion 201 is subjected to the third preset force, so that the support plate 330 moves toward the conductive body 100 until the abutting plate 340 abuts against the conductive body 100. At the same time, the support plate 330 is deformed toward the conductive body 100, wherein the first preset force is less than the second preset force and is less than the third preset force.

[0093] Among them, it is easy to understand that, under the condition of the third preset force, the feedback elasticity given to the operator assembling the battery 10 is relatively large, so that the operator can know that the battery 10 is installed in the wrong direction, and remind the operator to reinstall the battery 10 correctly, that is, when the other side of the battery 10 opposite to the positive and negative poles is aligned with the multi-contact conductor 200, part of the structure of the multi-contact conductor 200 (such as the bent bar 212) does not extend into the groove 11 of the battery 10.

[0094] In addition, it should be noted that the battery conductive sheet 1000 also includes an extension bar 400 and a plug-in terminal 500. The extension bar 400 is U-shaped. The extension bar 400 extends from the conductive body 100 to the other side of the battery containing box 2110 of the box body 2100. The conductive body 100 is connected to the conductive body 100 at one end of the extension bar 400, and the other end of the extension bar 400 is connected to the plug-in terminal 500. The plug-in terminal 500 is then electrically connected to an electrical unit in the electrical device. The electrical unit here can be understood as a circuit board or a motor, etc.

[0095] In summary, the battery conductive sheet 1000 includes a conductive body 100 and a multi-contact conductive body 200, the multi-contact conductive body 200 is connected to the conductive body 100, and a plurality of contact portions 201 distributed at intervals are formed on the multi-contact conductive body 200, at least two of the plurality of contact portions 201 are used to electrically contact the positive or negative pole of the battery 10 at the same time. Since the battery conductive sheet 1000 has a plurality of contact portions 201 for contacting the battery 10, it can be ensured that at least two of the contact portions 201 are electrically contacted with the positive or negative pole of the battery 10 at the same time, even if oxidation occurs at one of the contact positions, normal conduction between the battery 10 and the battery conductive sheet 1000 can still be ensured, thereby ensuring good conductivity between the battery 10 and the conductive sheet of the battery box.

[0096] In addition, the battery conductive sheet 1000 includes a reset member 300. When the battery 10 is correctly installed, for example, when the positive and negative electrodes of the battery 10 are aligned with the multi-contact conductor 200, since part of the structure of the multi-contact conductor 200 (such as the bent strip 212) will extend into the groove 11 of the battery 10, the arc-shaped deformation plate 320 will undergo a smaller elastic deformation, and the operator who assembles the battery 10 will have less elastic feedback.

[0097] If the battery 10 is incorrectly installed, for example, when the other side of the battery 10 opposite to the positive and negative poles is aligned with the multi-contact conductor 200, since some structures of the multi-contact conductor 200 (such as the bent bar 212) will not extend into the groove 11 of the battery 10, the arc-shaped deformation plate 320 will undergo a large elastic deformation, and the operator who assembles the battery 10 will be given a large elastic feedback. As a result, it can be known that the battery 10 is installed in the wrong direction, and the operator is reminded to reinstall the battery 10 correctly.

[0098] The battery box includes a box body 2100 and the above-mentioned battery conductive sheet 1000. The conductive body 100 is disposed in the box body 2100. The box body 2100 is used to accommodate the battery 10. The battery box has all the functions of the above-mentioned battery conductive sheet 1000.

[0099] The electrical device comprises the above-mentioned battery box, and the electrical device has all the functions of the above-mentioned battery box.

[0100] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
