Technical Field

[0001] The utility model relates to the technical field of electronic products, and more specifically, to a battery compartment. In addition, the utility model also relates to an electronic device comprising the battery compartment. Background Art

[0002] Battery compartments are widely used in various electronic products, especially outdoor portable electronic products. Battery compartments are used to store batteries to provide power to the electronic products.

[0003] The battery compartment in the prior art includes a compartment body and a battery compartment cover, which are connected by threads. After the battery is placed in the compartment body, the negative pole of the battery faces the battery compartment cover; the battery compartment cover is a metal product, the surface is oxidized, and the oxide layer is partially removed to enable effective current conduction; the threaded end of the compartment body used for threaded connection with the battery compartment cover is made of non-metal, and a conductive metal sleeve is embedded in the threaded end, and the end face of the metal sleeve has a certain protrusion relative to the threaded end of the battery compartment, so that after the battery compartment cover and the compartment body are screwed together, the inner end face of the battery compartment cover and the end face of the metal sleeve are in contact and conductive, and at the same time, the battery compartment cover is conductive to the negative pole of the battery.

[0004] In a battery compartment of this structure, the contact and conduction between the battery compartment cover and the end face of the metal sleeve is affected by the screwing length of the battery compartment cover and the compartment body, resulting in a small screwing tolerance of the battery compartment cover and a restricted screwing position. In actual use, due to the influence of friction resistance and the like, the battery compartment cover is often not screwed into place, resulting in the inability to effectively contact and conduct with the inner end face of the battery compartment cover and the end face of the metal sleeve.

[0005] Therefore, how to ensure effective conduction of the battery is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, an object of the present invention is to provide a battery compartment that can ensure effective conduction of the battery.

[0007] Another object of the utility model is to provide an electronic device comprising the battery compartment, wherein the battery can be effectively conducted.

[0008] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0009] A battery compartment, comprising:

[0010] The compartment body is used to place the battery, and one end of the compartment body is an open end;

[0011] A first conductive sleeve is embedded in the inner wall of the opening end, and one end of the first conductive sleeve extends out of the end surface of the opening end;

[0012] A battery compartment cover connected to the compartment body;

[0013] The first elastic conductive member is disposed between the battery compartment cover and the opening end, and includes a first contact portion and a second contact portion, wherein the first contact portion abuts against the protruding end of the first conductive sleeve, and the second contact portion abuts against the electrode of the battery.

[0014] Optionally, the first elastic conductive member is a special-shaped tower spring.

[0015] Optionally, the special-shaped tower spring includes:

[0016] A first conical spiral spring portion, comprising a first cone top and a first cone bottom, wherein the first cone top or a preset area adjacent to the first cone top is the first contact portion;

[0017] The second conical coil spring portion includes a second cone top and a second cone bottom, the second cone bottom is connected to the first cone top, the second conical coil spring portion is located inside the first conical coil spring portion, the first cone top and the second cone top form two wave peaks, and the second cone top is the second contact portion.

[0018] Optionally, after the battery compartment cover is connected to the compartment body, the battery compartment cover abuts against the first cone bottom and the second cone bottom respectively.

[0019] Optionally, a profile line of a cross section of the first elastic conductive member includes at least two wave peaks, wherein the two wave peaks serve as the first contact portion and the second contact portion.

[0020] Optionally, the battery compartment cover is provided with a first groove, and one end of the first elastic conductive member is clamped in the first groove.

[0023] Optionally, the battery compartment cover is a non-metallic part; or,

[0024] The battery compartment cover is a metal part, and an oxide layer is provided on its surface.

[0025] An electronic device comprises the above-mentioned battery compartment.

[0026] The battery compartment provided by the utility model has a first elastic conductive member disposed between the battery compartment cover and the open end of the compartment body. When the battery compartment cover is connected to the compartment body, the battery compartment cover squeezes the first elastic conductive member, causing the first elastic conductive member to produce elastic deformation. The elastic restoring force of the first elastic conductive member drives the first contact portion to press against the protruding end of the first conductive sleeve, and the second contact portion to press against the electrode of the battery, thereby ensuring that the first elastic conductive member is effectively connected to the first conductive sleeve and the electrode of the battery respectively. In addition, since the first elastic conductive member is elastic, the degree of squeezing of the first elastic conductive member by the battery compartment cover is different, and the elastic deformation of the first elastic conductive member is different.

[0027] That is to say, the battery compartment ensures the effectiveness of the first conductive sleeve and the battery being connected by adding a first elastic conductive member between the battery compartment cover and the open end of the compartment body; at the same time, the tolerance of the connection between the battery compartment cover and the compartment body is increased, the connection between the battery compartment cover and the compartment body is simplified, and the requirements for the connection accuracy between the battery compartment cover and the compartment body are reduced; moreover, the first elastic conductive member is arranged between the battery compartment cover and the open end of the compartment body, and is not easy to fall off, making the entire structure of the battery compartment more reliable and durable, and at the same time, the battery connection can withstand certain impact vibrations; further, the embodiment of the utility model utilizes the first elastic conductive member to The component realizes conduction between the first conductive sleeve and the battery, so that the conduction between the first conductive sleeve and the battery does not pass through the battery compartment cover, and the constraint of the battery compartment cover participating in the battery conduction is released, so that the battery conduction is all carried out in the enclosed space of the battery compartment, which is also conducive to effective insulation from the outside world. Therefore, when the battery is installed in the compartment body, the positive and negative electrodes of the battery can be interchanged, that is, the second contact portion can contact the negative electrode of the battery, and can also contact the positive electrode of the battery. When the second contact portion contacts the positive electrode of the battery, no leakage will occur, and the constraint on the installation direction of the positive and negative electrodes of the battery when installing the battery is released.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] The core of the utility model is to provide a battery compartment, which can ensure effective conduction of the battery 9. Another core of the utility model is to provide an electronic device including the battery compartment, wherein the battery 9 can be effectively conducted.

[0042] Please refer to Figure 1-3The utility model embodiment provides a battery compartment, including a compartment body 1, a first conductive sleeve 2, a battery compartment cover 3 and a first elastic conductive member 4, the compartment body 1 is used to set the battery 9, one end of the compartment body 1 is an open end; the first conductive sleeve 2 is embedded in the inner wall of the open end of the compartment body 1, and one end of the first conductive sleeve 2 extends out of the end surface of the open end of the compartment body 1; the battery compartment cover 3 is connected to the compartment body 1; the first elastic conductive member 4 is arranged between the battery compartment cover 3 and the open end of the compartment body 1, the first elastic conductive member 4 includes a first contact portion and a second contact portion, the first contact portion abuts against the extended end of the first conductive sleeve 2, and the second contact portion abuts against the electrode of the battery 9.

[0043] It should be noted that the first elastic conductive member 4 is elastic and conductive. Since the first elastic conductive member 4 is arranged between the battery compartment cover 3 and the open end of the compartment body 1, when the battery compartment cover 3 is connected to the compartment body 1, the battery compartment cover 3 squeezes the first elastic conductive member 4, causing the first elastic conductive member 4 to undergo elastic deformation. The elastic restoring force of the first elastic conductive member 4 drives the first contact portion to press against the protruding end of the first conductive sleeve 2, and presses the second contact portion against the electrode of the battery 9, thereby ensuring that the first elastic conductive member 4 is effectively conductive to the first conductive sleeve 2 and the electrode of the battery 9, respectively. In addition, since the first elastic conductive member 4 is elastic, the degree of squeezing of the battery compartment cover 3 on the first elastic conductive member 4 is different, and the elastic deformation of the first elastic conductive member 4 is different. Therefore, by utilizing the different deformations of the first elastic conductive member 4, the tolerance of the connection position between the battery compartment cover 3 and the compartment body 1 can be increased, that is, the conduction range is increased. For example, when the battery compartment cover 3 is threadedly screwed to the compartment body 1, the screwing tolerance of the battery compartment cover 3 and the compartment body 1 becomes larger. When the screwing length of the battery compartment cover 3 and the compartment body 1 is large, the degree of squeezing of the first elastic conductive member 4 is large, so that the elastic deformation of the first elastic conductive member 4 is large; when the screwing length of the battery compartment cover 3 and the compartment body 1 is small, the degree of squeezing of the first elastic conductive member 4 is small, so that the elastic deformation of the first elastic conductive member 4 is small, that is, under a larger screwing tolerance, the first elastic conductive member 4 can be effectively connected with the first conductive sleeve 2 and the electrodes of the battery 9 respectively.

[0044] That is to say, the embodiment of the utility model ensures the effectiveness of the conduction between the first conductive sleeve 2 and the battery 9 by adding the first elastic conductive member 4 between the battery compartment cover 3 and the open end of the compartment body 1; at the same time, the tolerance of the connection between the battery compartment cover 3 and the compartment body 1 is increased, the connection between the battery compartment cover 3 and the compartment body 1 is simplified, and the requirement for the connection accuracy between the battery compartment cover 3 and the compartment body 1 is reduced; moreover, the first elastic conductive member 4 is arranged between the battery compartment cover 3 and the open end of the compartment body 1, and is not easy to fall off, so that the entire structure of the battery compartment is more reliable and durable, and at the same time, the conduction of the battery 9 can withstand certain impact vibrations; further, the embodiment of the utility model utilizes the first elastic conductive member 4 to The electrical component 4 realizes the conduction between the first conductive sleeve 2 and the battery 9, so that the conduction between the first conductive sleeve 2 and the battery 9 does not pass through the battery compartment cover 3, and the constraint of the battery compartment cover 3 participating in the conduction of the battery 9 is released, so that the conduction of the battery 9 is all carried out in the enclosed space of the battery compartment, which is also conducive to effective insulation from the outside world. Therefore, when the battery 9 is installed in the compartment body 1, the positive and negative poles of the battery 9 can be interchanged, that is, the second contact portion can contact the negative pole of the battery 9, and can also contact the positive pole of the battery 9. When the second contact portion contacts the positive pole of the battery 9, no leakage will occur, and the constraint on the installation direction of the positive and negative poles of the battery 9 when installing the battery 9 is released.

[0045] It should be noted that this embodiment does not limit the specific structure of the first elastic conductive member 4, as long as the first elastic conductive member 4 includes a first contact portion and a second contact portion, the first contact portion can abut against the protruding end of the first conductive sleeve 2, and the second contact portion can abut against the electrode of the battery 9.

[0046] like Figure 1-3 As shown, in some embodiments, the first elastic conductive member 4 is a special-shaped tower spring. That is, the first elastic conductive member 4 in this embodiment adopts a special-shaped tower spring structure, which is light in weight, simple in processing technology, and easy to implement.

[0047] Of course, in other embodiments, the first elastic conductive member 4 may also adopt a structure of a special-shaped spring sheet; or may be an elastic member composed of an elastic member and a rigid structural member.

[0048] It should be noted that when the first elastic conductive part 4 is a special-shaped tower spring, the specific structure of the special-shaped tower spring is not limited, as long as the special-shaped tower spring includes a first contact portion and a second contact portion, the first contact portion can abut against the protruding end of the first conductive sleeve 2, and the second contact portion can abut against the electrode of the battery 9.

[0049] Considering the simplicity of the structure, please refer to Figure 4-8In some embodiments, the special-shaped tower spring includes a first conical spiral spring portion 41 and a second conical spiral spring portion 42, the first conical spiral spring portion 41 includes a first cone top 411 and a first cone bottom 412, the second conical spiral spring portion 42 includes a second cone top 421 and a second cone bottom 422, the second cone bottom 422 is connected to the first cone top 411, so that the first conical spiral spring portion 41 and the second conical spiral spring portion 42 form an integrated structure, and the second conical spiral spring portion 42 is located inside the first conical spiral spring portion 41, so that the first cone top 411 and the second cone top 421 form two peaks, the first cone top 411 or a preset area adjacent to the first cone top 411 is the first contact portion; the second cone top 421 is the second contact portion. That is to say, the first cone bottom 412 serves as an outer support ring, and the second cone bottom 422 serves as an inner support ring, so that the special-shaped tower spring has two support rings, the first cone top 411 serves as a wave crest, located between the first cone bottom 412 and the second cone bottom 422, and supported by the outer support ring and the inner support ring; the second cone top 421 serves as another wave crest, located at the innermost part of the special-shaped tower spring, and supported by the inner support ring alone; the first cone top 411 of the structure or the preset area adjacent to the first cone top 411 serves as the first contact portion, and the second cone top 421 serves as the second contact portion, that is, the first cone top 411 or the preset area adjacent to the first cone top 411 is used to abut against the extended end of the first conductive sleeve 2, and the second cone top 421 is used to abut against the electrode of the battery 9. The structure is simple in structure and convenient for molding and processing while meeting the requirements.

[0050] Furthermore, if Figure 6 and 7 As shown, in some embodiments, the second cone top 421 is higher than the first cone top 411. This is conducive to the second cone top 421 abutting against the electrode (whether positive or negative) of the battery 9, thereby improving the effectiveness of the special-shaped tower spring and the battery 9 being connected.

[0051] For further information, please refer to Figure 1 In some embodiments, after the battery compartment cover 3 is connected to the compartment body 1, the battery compartment cover 3 abuts against the first cone bottom 412 and the second cone bottom 422 respectively. That is, after the battery compartment cover 3 is connected to the compartment body 1, the battery compartment cover 3 contacts both the first cone bottom 412 and the second cone bottom 422, so that the special-shaped tower spring is firmly clamped between the battery compartment cover 3 and the compartment body 1, which is conducive to improving the structural stability. It can be understood that the first cone bottom 412 and the second cone bottom 422 can be located in the same plane, that is, the two are flush with each other, or they can be slightly staggered by a preset distance along the axial direction of the special-shaped tower spring.

[0052] In other embodiments, the profile of the cross section of the first elastic conductive member 4 includes at least two peaks, wherein the two peaks serve as the first contact portion and the second contact portion. It is understandable that there must be a trough between the two peaks, that is, in this embodiment, the profile of the cross section of the first elastic conductive member 4 also includes at least one trough to form at least two peaks, and two of the peaks serve as the first contact portion and the second contact portion, respectively, that is, one peak abuts against the protruding end of the first conductive sleeve 2, and the other peak abuts against the electrode of the battery 9. This structure is conducive to ensuring the reliability of the first elastic conductive member 4 contacting the electrodes of the first conductive sleeve 2 and the battery 9, respectively. In addition, in order to facilitate assembly, in some embodiments, the battery compartment cover 3 is provided with a first groove, and one end of the first elastic conductive member 4 is clamped in the first groove. That is to say, in this embodiment, a first groove is set so that one end of the first elastic conductive member 4 is installed in the first groove, so that the first elastic conductive member 4 is assembled with the battery compartment cover 3. The first groove can prevent the first elastic conductive member 4 from falling off. After the first elastic conductive member 4 and the battery compartment cover 3 are assembled, they can be assembled with the compartment body 1 as an integral component, so that the assembly is convenient, and the first elastic conductive member 4 can be prevented from falling off during the assembly process. After assembly, the position of the first elastic conductive member 4 can be guaranteed to be reliable, thereby improving the reliability of the first elastic conductive member 4 being electrically connected to the first conductive sleeve 2 and the battery 9 respectively.

[0053] Furthermore, considering the simplicity of the structure, Figure 3 As shown, in some embodiments, the battery compartment cover 3 is provided with an internal thread and a thread undercut groove 31, the internal thread is used for threaded connection with the compartment body 1, and the first groove is the thread undercut groove 31. That is to say, in this embodiment, the battery compartment cover 3 is threadedly connected to the compartment body 1, and the battery compartment cover 3 is connected to the compartment body 1 by screwing together, and this connection method is simple. In addition, when the internal thread is processed, a thread undercut groove 31 will be formed in the battery compartment cover 3. In this embodiment, the thread undercut groove 31 is used to clamp the first elastic conductive member 4, avoiding the need to separately open the first groove, thereby simplifying the structure of the battery compartment cover 3.

[0054] Furthermore, in some embodiments, the maximum outer diameter of the first elastic conductive member 4 is greater than the bottom diameter of the internal thread of the battery compartment cover 3 to prevent the first elastic conductive member 4 from falling off from the battery compartment cover 3 .

[0055] In addition, in order to improve the reliability of the conduction between the first elastic conductive member 4 and the first conductive sleeve 2, as shown in FIG. Figure 1As shown, in some embodiments, the extended end of the first conductive sleeve 2 is provided with a radially outwardly protruding flange 21, and the flange 21 is used to abut against the first contact portion. It can be understood that the flange 21 radially protrudes outward from the extended end of the first conductive sleeve 2, increasing the end surface area of ​​the extended end of the first conductive sleeve 2, thereby increasing the contact area between the first elastic conductive member 4 and the first conductive sleeve 2, and improving the reliability of the conduction between the first elastic conductive member 4 and the first conductive sleeve 2.

[0056] In addition, in order to improve the insulation effect between the battery compartment and the outside world, in some embodiments, the battery compartment cover 3 is a non-metallic part; or, the battery compartment cover 3 is a metal part with an oxide layer on its surface. That is to say, this embodiment uses a non-metallic battery compartment cover 3, or uses a metal material and sets an oxide layer on its surface, so that the battery compartment cover 3 has no conductive properties, so that the conduction is all carried out in a closed space, thereby effectively insulating the battery compartment from the outside world.

[0057] In addition, in order to improve the sealing performance of the connection between the battery compartment cover 3 and the compartment body 1, as Figure 1 As shown, in some embodiments, a seal 5 is provided between the battery compartment cover 3 and the compartment body 1, for sealing the connection between the battery compartment cover 3 and the compartment body 1. In some embodiments, the seal 5 cooperates with the inner circumference of the inner hole opening of the battery compartment cover 3, and the outer wall of the compartment body 1 is provided with a receiving groove for arranging the seal 5.

[0058] In addition, in order to achieve the conduction of the battery 9 toward the end of the compartment body 1 away from the battery compartment cover 3, as shown in FIG. Figure 1-3 As shown, in some embodiments, one end of the compartment body 1 away from the battery compartment cover 3 is a closed end, a second conductive sleeve 6 is provided in the closed end, a second elastic conductive member 7 is provided in the second conductive sleeve 6, one end of the second elastic conductive member 7 is connected to the second conductive sleeve 6, and the other end is used to be connected to the electrode of the battery 9.

[0059] It should be noted that the present embodiment does not limit the specific structure of the second elastic conductive member 7, as long as the conduction between the battery 9 and the second conductive sleeve 6 can be achieved. In some embodiments, the second elastic conductive member 7 is a tower spring.

[0060] Furthermore, to facilitate assembly, in some embodiments, a second groove is provided in the second conductive sleeve 6, and one end of the second elastic conductive component 7 is embedded in the second groove, so that the second elastic conductive component 7 can be clamped by the second groove, so that the second elastic conductive component 7 is assembled with the second conductive sleeve 6 to prevent the second elastic conductive component 7 from falling off from the second conductive sleeve 6.

[0061] In addition, in order to prevent the positive electrode and the negative electrode of the battery 9 from being directly connected, Figure 1-3As shown, in some embodiments, an insulating tube 8 is provided between the first conductive sleeve 2 and the second conductive sleeve 6. In some embodiments, one end of the insulating tube 8 abuts against the end surface of the first conductive sleeve 2, and the other end of the insulating tube 8 abuts against the end surface of the second conductive sleeve 6.

[0062] It should be noted that the embodiments of the utility model do not limit the specific materials of the first conductive sleeve 2 and the second conductive sleeve 6, as long as they can conduct electricity. In some embodiments, the first conductive sleeve 2 and the second conductive sleeve 6 are both metal sleeves.

[0063] In addition to the above-mentioned battery compartment, the present invention also provides an electronic device including the battery compartment disclosed in the above-mentioned embodiment. The structures of other parts of the electronic device are referred to the prior art, which will not be described in detail herein. In other words, this embodiment does not limit the specific type of electronic device, as long as it includes a battery compartment.

[0064] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
