It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0031] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0032] The inventors discovered that the button battery is a device that converts chemical energy into electrical energy. It has positive and negative terminals. Button batteries are portable, easy to charge, unaffected by external factors, and relatively reliable, thus enjoying widespread use. Button batteries are closely related to human life, but they require a battery holder for use. Existing battery holders have the following drawbacks: they mainly use a circular base to hold the battery, pressing it in with a squeezing motion. The CR2032 button battery holder currently on the market is relatively large, occupying significant space and unsuitable for installation in limited spaces.

[0033] To solve the above technical problems, such as Figure 1 As shown, this utility model provides a battery mounting device suitable for button batteries, which includes: a housing 1, a circuit board 2, a positive electrode spring 3, and a negative electrode spring 4; wherein, the housing 1 has an internal accommodating space for accommodating the button battery; one end of the positive electrode spring 3 is fixed to the circuit board 2 from top to bottom, and one end of the negative electrode spring 4 is fixed to the circuit board 2 from bottom to top; the positive electrode spring 3 and the negative electrode spring 4 form a clamping structure on the side of the circuit board 2 for clamping the button battery.

[0034] Specifically, the button battery mounting device is suitable for the application of button batteries in confined spaces. The positive electrode spring 3 and negative electrode spring 4 are made of conductive material, specifically stainless steel. The positive electrode spring 3 provides downward pressure on the button battery to limit its vertical movement; the negative electrode spring 4 bears the downward pressure, thus ensuring a stable conductive connection between the positive and negative electrode springs and the button battery under any extreme conditions. The circuit board 2 is a PCB board, which carries electronic components and integrated circuits formed by the connections between these components. It can reliably implement various control functions and features high integration, small size, high performance, and lightweight aesthetics. The circuit board 2 receives and fixes the positive and negative electrode springs 3 and 4, which are electrically connected to the integrated circuits on the circuit board 2. When installing a button battery into the button battery mounting device, the button battery is inserted horizontally through the opening of the clamping structure, which fixes the button battery to the side of the circuit board 2 and makes a stable electrical connection with the current plate. At this time, the outer shell 1, the positive electrode spring 3, and the negative electrode spring 4 together form a receiving space for accommodating the button battery. Since the circuit board 2 and the button battery are coaxially arranged in the horizontal direction, they have the same height, which will not cause the height of the outer shell 1 to increase, thereby increasing the portability of the button battery mounting device.

[0035] Please also refer to Figure 1 and Figure 7 The internal space of the outer casing 1 is used to fix the circuit board 2, the positive electrode spring 3 and the negative electrode spring 4. Specifically, the outer casing 1 can also be provided with a first fixing groove 112 and a second fixing groove 113. The two ends of the circuit board 2 can slide back and forth in the first fixing groove 112 and the second fixing groove 113 respectively, thereby fixing the position of the circuit board 2, the positive electrode spring 3 and the negative electrode spring 4, and preventing the circuit board 2 from shaking up and down, which would cause the casing to be squeezed and deformed between the positive electrode spring 3 and the negative electrode spring 4.

[0036] Furthermore, please refer to the following: Figure 1 and Figure 2 The circuit board 2 has at least one positive through-hole 21 for fixing the positive electrode spring 3 of the button battery and at least one negative through-hole 22 for fixing the negative electrode spring 4 of the button battery. Specifically, the positive through-hole 21 is connected to the voltage input terminal of the integrated circuit on the circuit board 2, and the negative through-hole 22 is connected to the voltage output terminal of the integrated circuit on the circuit board 2. Thus, the button battery forms a circuit with the integrated circuit on the circuit board 2 through the positive electrode spring 3, the positive through-hole 21, the negative electrode spring 4, and the negative through-hole 22.

[0037] Furthermore, please refer to the following: Figure 2 and Figure 3 The positive electrode spring 3 includes a limiting part 31, a pressing part 32, and an upper spring 33. The limiting part 31 is inserted into the positive electrode through hole 21 to restrict the fixed position of the button battery. The pressing part 32 is perpendicular to the limiting part 31 and partially surrounds the upper surface of the button battery. The upper spring 33 extends downwards at an angle from the lower surface of the pressing part 32 to abut against the upper surface of the button battery. Correspondingly, the negative electrode spring 4 includes a supporting part 41, a fixing part 42, and a lower spring 43. The supporting part 41 supports the button battery. The fixing part 42 is vertically disposed on the supporting part 41 and inserted into the negative electrode through hole 22. The lower spring 43 extends upwards at an angle from the upper surface of the supporting part 41 to abut against the lower surface of the button battery.

[0038] Specifically, the upper spring piece 33 and the lower spring piece 43 are made of conductive metal with a certain degree of elasticity. Their elastic pressure ensures a conductive connection between the spring piece and the button battery under any extreme conditions. The number of limiting portions 31 of the positive electrode spring piece 3 corresponds to the number of positive electrode through holes 21, and the number of fixing portions 42 of the negative electrode spring piece 4 corresponds to the number of negative electrode through holes 22. The limiting portions 31 abut against the side surface of the button battery, and the lower end of the limiting portions 31 is fixed in the positive electrode through hole 21 by welding. Preferably, there are three limiting portions 31, which define the position of the button battery from three directions. There are two fixing portions 42, which provide support for the button battery. It should be noted that this structure can also be adapted to the ultra-thin design of various button batteries by modifying the specific size and height of the positive electrode spring 3 or the negative electrode spring 4, such as the application of button batteries of different specifications such as AG series, LR series, and SR series in ultra-thin structure scenarios. This utility model will not be elaborated here.

[0039] Furthermore, please participate Figure 1 , Figure 4 , Figure 5 and Figure 6 , Figure 6 For the shell cover 12 edge Figure 4The diagram shows a cross-section obtained by cutting along direction AA. The outer casing 1 includes a housing 11 and a cover 12, which are detachably connected. The housing 11 has a space for accommodating the circuit board 2, the positive electrode spring 3, and the negative electrode spring 4. The inner surface of the cover 12 has a first limiting part 122 for abutting against the side surface of the button battery. The cover 12 and the housing 11 can be connected by a snap-fit, hinge, thread, or sliding connection to allow the outer casing 1 to open and close. Preferably, the cover and the housing 11 are connected by a snap-fit. The first recessed portion 121 of the housing 11 has a fixing hole 61, and the cover 12 has a protruding button 62 corresponding to the fixing hole 61 on its upper surface. The upper surface of the protruding button 62 is inclined.

[0040] Specifically, when the cover 12 is closed, the first recessed portion 121 slides inside the cover 12, causing the inclined surface of the upper surface of the protruding button 62 to abut against the inside of the cover 12 and slide into the inside of the cover 12, forming an interference fit with the cover 12. When the edge of the first recessed portion 121 of the cover 12 abuts against the second limiting portion 111 of the cover 12, the protruding button 62 pops up when it slides to the position below the fixing hole 61, and locks the cover 12 into the housing 11 to prevent the cover 12 from sliding. When it is necessary to remove or insert a button battery, the user can press the protruding button 62 to pull the cover 12 off the housing 11 for easy replacement of the button battery.

[0041] For further information, please refer to [link / reference]. Figure 1 , Figure 5 and Figure 7A first recessed portion 121 is provided at the edge of the cover 12, and a second limiting portion 111 is provided on the inner surface of the housing 11. The first recessed portion 121 and the second limiting portion 111 of the housing 11 are directly opposite each other. The thickness of the outer shell 1 of the first recessed portion 121 is less than the thickness of the outer shell 1 of other parts of the cover 12. Optionally, an elastic sealing structure 5 is provided on the second limiting portion 111 of the housing 11 and / or the first recessed portion 121 of the cover 12. Thus, when the cover 12 is pulled out, a button battery can be pushed into the clamping structure of the housing 11 or an existing button battery can be pulled out. When the cover 12 is pushed up, since the first recessed portion 121 of the cover 12 is opposite to the second limiting portion 111 of the housing 11, the first recessed portion 121 slides into the inside of the cover 12, and when it abuts against the second limiting portion 111, the elastic sealing structure 5 further improves the sealing performance of the button battery mounting device, enhancing the sealing effect. Furthermore, a first auxiliary protrusion 123 and a second auxiliary protrusion 124 are respectively provided opposite to each other on the outer surface of the first recessed portion 121. A first auxiliary limiting portion 114 and a second auxiliary limiting portion 115 are respectively provided at corresponding positions of the first auxiliary protrusion 123 and the second auxiliary protrusion 124 on the inner surface of the shell compartment 11. The first auxiliary limiting portion 114 and the second auxiliary limiting portion 115 are positioning grooves of corresponding length. When the shell cover 12 is fastened to the shell compartment 11, the first auxiliary protrusion 123 slides inside the first auxiliary limiting portion 114 and abuts against the first auxiliary limiting portion 114 when the outer shell 1 is fastened. Correspondingly, the second auxiliary protrusion 124 slides in the first auxiliary limiting portion 114 and abuts against the second auxiliary limiting portion 115 when the outer shell 1 is fastened, thereby preventing the shell cover 12 from rotating relative to the shell compartment 11 and playing a role in auxiliary fixation.

[0042] Secondly, this utility model provides an electronic control device, such as... Figure 8 As shown, it includes the aforementioned battery mounting device suitable for button batteries and a button battery, wherein the button battery is disposed in the receiving space of the button battery mounting device. The button battery mounting device is specifically as described above for the battery mounting device suitable for button batteries, and will not be described again here.

[0043] Specifically, this utility model provides a button battery spring contact structure suitable for button batteries used in confined spaces. After assembly, the circuit board is inserted into and fixed inside the casing. The positive and negative electrode spring contacts are soldered onto the circuit board, forming a receiving space for the button battery together with the button battery cover. The casing includes a housing and a cover. The button battery is fixed inside the casing by the cover's snap-fit ​​mechanism. The positive and negative electrode spring contacts are located at the end of the receiving space near the cover, while the circuit board is located at the end of the receiving space away from the cover. The button battery can be replaced when the cover is removed. The button battery model is CR2032, but other models can also be used, which will not be elaborated here. In this structure, the button battery and circuit board are placed on the same plane rather than stacked, thereby reducing product space. The height of the assembled circuit board, button battery, positive electrode spring contact, and negative electrode spring contact can be controlled to within 4mm, and the effective height of the product with the casing is controlled to within 6.5mm. In a narrow and limited space, the positive electrode spring at the top and the negative electrode spring at the bottom are soldered to the circuit board. Together with the outer shell, the CR2032 button battery is fixed and supplies power to the integrated circuits on the circuit board, so that the product meets the requirements of small size and portability.

[0044] In summary, this utility model provides a battery mounting device and electronic control equipment suitable for button batteries. The battery mounting device includes: a housing, a circuit board, a positive electrode spring, and a negative electrode spring. The housing has an internal space for accommodating the button battery. One end of the positive electrode spring is fixed to the circuit board from top to bottom, and one end of the negative electrode spring is fixed to the circuit board from bottom to top. The positive and negative electrode springs form a clamping structure on the side of the circuit board for holding the button battery. By adopting the above technical solution of this utility model, the connection reliability between the spring and the button battery, and between the spring and the circuit board, can be improved. The clamping structure, which allows the button battery to be inserted from the side of the circuit board, prevents it from falling out, reduces the overall height of the button battery mounting device, and improves its overall portability. Simultaneously, the clamping structure formed by the positive and negative electrode springs can fix the button battery in the internal space of the button battery mounting device, simplifying the button battery mounting structure and reducing production costs while ensuring the button battery is securely fixed.

[0045] It should be understood that the application of this utility model is not limited to the examples above.
