[0019] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0020] In the description of this application, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc. used in this application to indicate the orientation or positional relationship are based on the positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and are not intended to indicate or imply that the device and element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] In the description of this application, it should be understood that the terms "first," "second," etc., are used to describe various types of information, but these terms are not limited to them and are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0022] In practical applications, the positive electrode of battery 5 is generally designed as a raised structure. Because the contact between the positive electrode of battery 5 and the electrode plate is unstable, when the battery compartment is impacted, battery 5 is prone to separate from the electrode plate, resulting in unstable electrical connection.

[0023] In view of this, such as Figures 1 to 7 As shown, this application embodiment provides a battery compartment, which includes a housing 1, a connecting piece 2, a positive electrode 3, and a negative electrode 4. The housing 1 is provided with a receiving groove 10 for placing a pair of batteries 5. The receiving groove 10 has a first end 11 and a second end 12 disposed opposite to each other. The positive electrode 3 and the negative electrode 4 are spaced apart at the first end 11 of the receiving groove 10, and the connecting piece 2 is provided at the second end 12 of the receiving groove 10. The positive electrode 3 is provided with a first spring 31 facing the connecting piece 2, and the negative electrode 4 is provided with a first spring 41 facing the connecting piece 2. The connecting piece 2 is provided with a second spring 21 facing the positive electrode 3 and a second spring 22 facing the negative electrode 4. The first spring 31 and the second spring 22 are used to abut against the positive electrode of the battery 5, and the first spring 41 and the second spring 21 are used to abut against the negative electrode of the battery 5.

[0024] In this embodiment, the connecting piece 2, the positive electrode 3, and the negative electrode 4 are all conductive electrode pieces. "One pair" in this embodiment means two batteries. The receiving slot 10 includes two parallel slots, with two batteries 5 respectively housed in opposite directions within the two slots, forming a series battery structure via the connecting piece 2. The positive electrode of one battery 5 abuts against the first spring 31 on the positive electrode 3, and the negative electrode abuts against the second spring 21 on the connecting piece 2. The positive electrode of the other battery 5 abuts against the second spring 22 on the connecting piece 2, and the negative electrode abuts against the first spring 41 on the negative electrode 4. The first spring 31, the second spring 22, the first spring 41, and the second spring 21 are all conductive.

[0025] Based on the above technical solution, in this embodiment, the first spring 31 and the second spring 22 abut against the protruding structure of the positive electrode of the two batteries 5 respectively through the elastic action of the first spring 31 and the second spring 22. The elasticity of the spring can generate continuous pressure, so that the positive electrode of the battery 5 is tightly attached to the spring. At the same time, the first spring 41 and the second spring 21 abut against the negative electrode of the battery 5, so that the two batteries 5 are firmly installed in the receiving groove 10, thereby enhancing the contact between the battery 5 and the electrode sheet, avoiding the battery compartment from being hit and causing the battery 5 to loosen, and improving the electrical connection stability between the battery 5 and the electrode sheet.

[0026] In some embodiments, such as Figure 5 As shown, one end of the first spring piece 31 is connected to the side of the positive electrode plate 3, and the other end of the first spring piece 31 extends along the positive electrode plate 3 toward the connecting piece 2 and is spaced apart from the positive electrode plate 3, so that the first spring piece 31 can generate elastic deformation in a direction perpendicular to the surface of the positive electrode plate 3. When the battery 5 is placed into the receiving groove 10, the positive electrode of the battery 5 presses the first spring piece 31, causing the first spring piece 31 to deform and generate elastic force, thereby tightly abutting against the positive electrode of the battery 5, ensuring stable contact between the first spring piece 31 and the positive electrode plate 3.

[0027] In this embodiment, one end of the first spring sheet 31 is connected to the side of the positive electrode plate 3, ensuring a stable connection between the first spring sheet 31 and the positive electrode plate 3 while also allowing space for elastic movement at its other end. This allows the first spring sheet 31 to bend and deform using the connection point between the first spring sheet 31 and the positive electrode plate 3 as a fulcrum when subjected to external force, without detaching from the positive electrode plate 3. Because the first spring sheet 31 is elastic, after being compressed by external force, the first spring sheet 31 will bend and deform in a direction perpendicular to the surface of the positive electrode plate 3, generating an elastic force opposite to the compression direction. This elastic force ensures that the first spring sheet 31 is tightly pressed against the positive electrode of the battery 5.

[0028] For example, one end of the first spring 31 is connected to the top side of the positive electrode 3, and the first spring 31 and the positive electrode 3 can be an integrally formed structure.

[0029] In some embodiments, such as Figure 5 As shown, the positive electrode 3 is also provided with a first protrusion 32 facing the first spring 31; when the positive electrode of the battery 5 abuts against the first spring 31, the first spring 31 abuts against the first protrusion 32, and the first protrusion 32 is used to enhance the connection stability between the first spring 31 and the positive electrode 3.

[0030] Specifically, by increasing the contact area between the first spring plate 31 and the positive electrode plate 3 through the first protrusion 32, the contact resistance is reduced, allowing current to be conducted between the positive electrode plate 3 and the first spring plate 31, thus avoiding energy loss and heat generation due to poor contact. When the positive electrode of the battery 5 comes into contact with the first spring plate 31, the first spring plate 31 undergoes elastic deformation and comes into contact with the first protrusion 32. The surface of the first protrusion 32 and the deformed part of the first spring plate 31 form a large contact area, which can effectively reduce the contact resistance.

[0031] In some embodiments, such as Figure 7 As shown, one end of the second spring piece 22 is connected to the side of the connecting piece 2, and the other end of the second spring piece 22 extends along the side of the connecting piece 2 toward the negative electrode 4, and is spaced apart from the connecting piece 2, so that the second spring piece 22 can generate elastic deformation in a direction perpendicular to the surface of the connecting piece 2. When the positive electrode of the battery 5 presses the second spring piece 22, the second spring piece 22 deforms and generates elastic force, thereby tightly abutting against the positive electrode of the battery 5, ensuring stable contact between the second spring piece 22 and the connecting piece 2.

[0032] In this embodiment, one end of the second spring piece 22 is connected to the side of the connecting piece 2, ensuring a stable connection between the second spring piece 22 and the connecting piece 2 while also allowing space for elastic movement at its other end. This allows the second spring piece 22 to bend and deform using the connection point between the second spring piece 22 and the connecting piece 2 as a fulcrum when subjected to external force, without detaching from the connecting piece 2. Because the second spring piece 22 is elastic, after being compressed by external force, it will bend and deform in a direction perpendicular to the surface of the connecting piece 2, generating an elastic force opposite to the compression direction. This elastic force ensures that the spring piece 22 is tightly pressed against the positive electrode of the battery 5.

[0033] For example, one end of the second spring 22 is connected to the top side of the connecting piece 2, and the second spring 22 and the connecting piece 2 can be integrally formed.

[0034] In some embodiments, such as Figure 7 As shown, the connecting piece 2 is also provided with a second protrusion 23 facing the second spring piece 22. When the positive terminal of the battery 5 abuts against the second spring piece 22, the second spring piece 22 abuts against the second protrusion 23. The second protrusion 23 is used to enhance the connection stability between the second spring piece 22 and the connecting piece 2.

[0035] Specifically, by increasing the contact area between the second spring 22 and the connecting piece 2 through the second protrusion 23, the contact resistance is reduced, allowing current to be conducted between the second spring 22 and the connecting piece 2, thus avoiding energy loss and heat generation due to poor contact. When the positive terminal of the battery 5 comes into contact with the second spring 22, the second spring 22 undergoes elastic deformation and comes into contact with the second protrusion 23. The surface of the second protrusion 23 and the deformed part of the second spring 22 form a large contact area, which can effectively reduce the contact resistance.

[0036] In some embodiments, such as Figure 8 As shown, the first end 11 of the receiving groove 10 is provided with a first limiting groove 13 and a second limiting groove 14. The positive electrode 3 is assembled in the first limiting groove 13, which firmly restricts the positive electrode 3 to the first end 11 of the receiving groove 10. The negative electrode 4 is assembled in the second limiting groove 14, which firmly restricts the negative electrode 4 to the first end 11 of the receiving groove 10, preventing the positive electrode 3 and the negative electrode 4 from becoming loose. Even if the battery compartment is subjected to severe vibration or impact, the positions of the positive electrode 3 and the negative electrode 4 can be kept relatively stable, ensuring stable contact between the battery 5 and the two electrode plates.

[0037] In some embodiments, corresponding markings (such as positive and negative symbols) are provided in the first limiting groove 13 and the second limiting groove 14 respectively, so as to facilitate the quick installation of the positive electrode 3 and the negative electrode 4 and improve the assembly efficiency of the battery compartment.

[0038] In some embodiments, such as Figure 8 As shown, the second end 12 of the receiving groove 10 is provided with a third limiting groove 15. The connecting piece 2 is assembled in the third limiting groove 15. The third limiting groove 15 firmly restricts the connecting piece 2 to the second end 12 of the receiving groove 10 to prevent the connecting piece 2 from becoming loose. Even if the battery compartment is subjected to severe vibration or impact, the position of the connecting piece 2 can be kept relatively stable to ensure stable contact between the battery 5 and the connecting piece 2.

[0039] In some embodiments, such as Figure 9 As shown, there are the first card connector 16, the second card connector 17, and the third card connector 18.

[0040] Specifically, the receiving groove 10 includes two parallel grooves. At the first end 11 of the receiving groove 10, and along the width direction of the groove, the first snap-fit ​​member 16 and the third snap-fit ​​member 18 are respectively spaced apart on both sides of one of the grooves to form a first limiting groove 13. The second snap-fit ​​member 17 and the third snap-fit ​​member 18 are respectively spaced apart on both sides of the other groove to form a second limiting groove 14.

[0041] In this embodiment, when the positive electrode 3 is assembled in the first limiting groove 13, the first locking member 16 and the third locking member 18 restrict the positive electrode 3 from both sides, and the first spring 31 extends a certain distance from the clearance channel between the first locking member 16 and the third locking member 18 into the receiving groove 10, thereby having a certain distance from the positive electrode 3. When the negative electrode 4 is assembled in the second limiting groove 14, the second locking member 17 and the third locking member 18 restrict the negative electrode 4 from both sides, and the first spring 41 extends a certain distance from the clearance channel between the second locking member 17 and the third locking member 18 into the receiving groove 10.

[0042] In some embodiments, at the second end 12 of the receiving groove 10 and in the width direction of the groove body, a plurality of fourth snap-fit ​​members (not shown in the figure) are provided at intervals in the groove body, and the plurality of fourth snap-fit ​​members form a third limiting groove 15, and the connecting piece 2 is assembled in the third limiting groove 15.

[0043] In some embodiments, the first snap-fit ​​member 16, the second snap-fit ​​member 17, and the third snap-fit ​​member 18 are integrally formed with the housing 1. For example, they are formed in the receiving groove 10 by injection molding.

[0044] In some embodiments, such as Figure 2 and Figure 4 As shown, the battery compartment also includes a main control board 6, which is mounted on the side of the housing 1 opposite to the receiving groove 10, making the battery compartment structure more compact. Figure 5 As shown, the positive electrode 3 has a first extension 33, which passes through the first limiting groove 13, through the housing 1, and connects to the main control board 6; Figure 6 As shown, the negative electrode 4 has a second extension 42, which passes through the second limiting groove 14 and the housing 1 to connect with the main control board 6. The positive electrode 3 and the negative electrode 4 are electrically connected to the main control board 6 through the first extension 33 and the second extension 42 respectively, thereby enabling the battery 5 to supply power to the main control board 6.

[0045] In some embodiments, such as Figure 9 As shown, the bottom of the first limiting groove 13 and the second limiting groove 14 are each provided with a through hole 19. The two through holes 19 are spaced apart on the housing 1. The first extension 33 and the second extension 42 pass through the through holes 19 and are connected to the main control board 6.

[0046] In some embodiments, such as Figure 1 As shown, the battery compartment also includes a cover assembly 7, which covers the opening of the receiving groove 10 to seal the battery 5, preventing dust from entering the receiving groove 10 and thus avoiding affecting the performance of the battery 5. Furthermore, the cover assembly 7 can reduce collisions and impacts on the battery 5, lowering the risk of damage to the battery 5.

[0047] In some embodiments, such as Figure 4 As shown, the cover assembly 7 includes a first cover 71 and a second cover 72. The second cover 72 is the battery compartment cover, which covers most of the opening of the receiving groove 10 via a snap-fit ​​mechanism, serving as the primary sealing cover. The first cover 71 is a push plate used to cover a smaller portion of the opening of the receiving groove 10. The first cover 71 and the second cover 72 together cover the opening of the receiving groove 10. When the battery 5 needs to be replaced, the first cover 71 is first slid and pushed to separate it from the opening of the receiving groove 10, and then the second cover 72 is removed to open the opening of the receiving groove 10.

[0048] In some embodiments, such as Figure 4 As shown, the battery compartment also includes a waterproof ring 8, which is fitted at the opening of the receiving groove 10 and abuts against the cover assembly 7 and the housing 1 respectively, to prevent liquid from entering the receiving groove 10 from the connection between the cover assembly 7 and the housing 1.

[0049] Specifically, the waterproof ring 8 can be made of an elastic material, such as rubber or silicone. When the waterproof ring 8 is assembled into the opening of the receiving groove 10 and abuts against the cover assembly 7 and the housing 1 respectively, the waterproof ring 8 undergoes elastic deformation due to the compression from the cover assembly 7 and the housing 1, so that the waterproof ring 8 tightly fills the gap between the cover assembly 7 and the housing 1, forming a sealing barrier to prevent liquids (such as rainwater) from entering the receiving groove 10 from the connection, thereby improving the waterproof performance of the battery compartment.

[0050] Secondly, this application also provides an electronic device that includes a battery compartment.

[0051] Specifically, the electronic device includes a laser rangefinder, a TV remote control, an air conditioner remote control, etc., and the specific type of electronic device is not limited here. Since the electronic device includes the battery compartment, it has all the beneficial effects of a battery compartment, which will not be elaborated further here.
