Description

Technical Field

[0001] This application relates to the field of industrial control technology, and in particular to a button battery compartment and electronic device. Background Technology

[0002] Currently, common button battery compartments include two clamping arms, the inner sides of which are usually curved to fit the circular shape of the button battery. The button battery compartment uses these two clamping arms to hold the button battery and insert it into the electronic device.

[0003] However, due to the size limitations of the battery compartment, the clamping arms are usually designed to be long and thin. Long and thin clamping arms are prone to deformation and can wobble when inserting electronic devices. This can cause the coin cell battery to come loose during insertion and removal from the battery compartment, resulting in poor contact between the coin cell battery and the electronic device. Utility Model Content

[0004] The purpose of this application is to provide a button battery compartment and an electronic device to improve the stability of the connection between the button battery and the button battery compartment. The specific technical solution is as follows:

The first direction is perpendicular to the second direction in which the button battery compartment is inserted into the electronic device and parallel to the bottom surface of the groove.

[0008] A spring-loaded groove is provided between the elastic arm and the battery bracket. When the elastic arm is pressed, it can move toward the spring-loaded groove and return to its original position after the pressure is released.

[0009] The negative electrode spring inside the electronic device has a spring force generated by the deformation of the negative electrode spring, which can push the button battery compartment out of the battery insertion port.

[0010] In some embodiments of this application, a bracket guide groove is provided on the side of the battery holder away from the groove, and the bracket guide groove extends along the second direction; the opening of the bracket guide groove faces the second direction, and the guide slider inside the electronic device can slide into the bracket guide groove.

[0011] In some embodiments of this application, the elastic arm is provided with an inclined rib on the side away from the battery bracket;

[0012] The width of the inclined rib decreases along the second direction; after the button battery compartment is inserted into the battery insertion port, the orthographic projection of the inclined rib onto the plane containing the bottom surface of the groove is located outside the orthographic projection of the battery insertion port onto the plane containing the bottom surface of the groove.

[0013] In some embodiments of this application, a snap-fit ​​portion is provided on the side of the elastic arm away from the battery holder;

[0014] The latching portion extends in a direction away from the battery holder and is used to latch with the edge of the battery insertion port of the electronic device.

[0015] In some embodiments of this application, the elastic arm is provided with a wrench portion on the side away from the battery bracket, and extends in a direction away from the battery bracket;

[0016] The wrench part can drive the elastic arm to move toward the spring groove under the action of external force.

[0017] In some embodiments of this application, the length of the spring-loaded groove along the second direction accounts for 85%-95% of the length of the battery holder along the second direction;

[0018] And / or,

[0019] The width of the rebound groove along the first direction is 1mm-2mm.

[0020] In some embodiments of this application, a battery fixing part protruding outward from the inner sidewall of the groove is provided;

[0021] The battery fixing part is spaced apart from the bottom surface of the groove, and the battery fixing part is used to cooperate with the bottom surface of the groove to clamp the button battery.

[0022] This application also provides an electronic device, including: a device housing and a button battery compartment of any of the above embodiments;

[0023] The device housing includes: a battery insertion port and a circuit board, the circuit board including a negative electrode spring;

[0024] The button battery compartment can be inserted into the device housing through the battery insertion port.

[0025] In some embodiments of this application, the negative electrode spring is Y-shaped, and the elastic force generated by the deformation of the free end of the negative electrode spring can push the button battery compartment out of the battery insertion port.

[0026] In some embodiments of this application, the device housing further includes a battery compartment limiting frame;

[0027] An inclined rib is provided on the side of the elastic arm away from the battery bracket;

[0028] The battery compartment limiting frame includes: a first limiting portion extending along the first direction and a second limiting portion disposed at both ends of the first limiting portion and extending along the second direction;

[0030] The second limiting part can abut against both sides of the battery holder along the first direction to restrict the movement of the battery holder along the first direction.

[0031] Beneficial effects:

[0032] This application provides a button battery compartment and an electronic device. The battery holder of the button battery compartment includes a groove, in which a button battery can be installed. The positive electrode surface of the button battery can contact the bottom surface of the groove, and the bottom surface can support the button battery, increasing the contact area between the positive electrode surface of the button battery and the battery holder, improving the stability between the two, and thus reducing the probability of poor contact between the button battery and the electronic device.

[0033] Furthermore, the button battery compartment is equipped with a spring arm. During the insertion of the button battery compartment into the electronic device, the spring arm deforms towards the spring-loaded groove, allowing the button battery compartment to be inserted into the electronic device. After the battery holder is inserted into the electronic device, the spring arm returns to its original position, locking itself into the electronic device for self-locking.

[0034] Inside the electronic device, the negative electrode spring contacts the button battery, and the button battery deforms the negative electrode spring by squeezing it. When it is necessary to remove the button battery compartment, squeezing the elastic arm causes it to move towards the battery holder, releasing the self-locking mechanism. The elastic force generated by the deformation of the negative electrode spring can push the button battery and the button battery compartment out of the battery insertion port of the electronic device.

[0035] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0055] This application provides a button battery compartment, such as Figure 1a and Figure 1b As shown, Figure 1a A first-view structural schematic diagram of the button battery compartment provided in this application; Figure 1b This is a second-view structural schematic diagram of the button battery compartment provided in this application. The button battery compartment includes: a battery holder 1 and a spring arm 2; the battery holder 1 has a groove 11 for accommodating a button battery 3, the inner sidewall of the groove 11 is arc-shaped, and the bottom surface of the groove 11 is flat; the battery holder is provided with a spring arm 2 along at least one side of a first direction X, for engaging with the edge of the battery insertion port 41 of the electronic device to fix the button battery compartment to the electronic device, the first direction X is perpendicular to the second direction Y in which the button battery compartment is inserted into the electronic device, and parallel to the bottom surface of the groove 11; a spring-loaded groove 12 is provided between the spring arm 2 and the battery holder 1, the spring arm 2 can move toward the spring-loaded groove 12 after being pressed, and reset after the pressure is released; a negative electrode spring 422 inside the electronic device, the elastic force generated by the deformation of the negative electrode spring 422 can push the button battery compartment out of the battery insertion port 41.

[0056] In this embodiment, the battery holder 1 of the button battery compartment includes a recess 11. For example... Figures 2a to 2c As shown, Figure 2a for Figure 1a The diagram shown illustrates the structure of the button battery compartment for loading button batteries. Figure 2b for Figure 2a Rear view; Figure 2c for Figure 2aThe side view shows the button battery 3, which can be installed in the recess 11. The positive electrode plane of the button battery 3 can contact the bottom surface of the recess 11, and the bottom surface of the recess 11 can support the button battery 3; the arc-shaped inner wall of the recess 11 fits against the side wall of the button battery 3 to position the button battery 3. Increasing the contact area between the positive electrode plane of the button battery 3 and the battery holder 1 improves the stability between them, thereby reducing the probability of poor contact between the button battery 3 and the electronic device.

[0057] Furthermore, the button battery compartment is equipped with a spring arm 2. During the insertion of the button battery compartment into the electronic device, the spring arm 2 can deform towards the spring-loaded groove 12 to allow the button battery compartment to be inserted into the electronic device. After the battery holder 1 is inserted into the electronic device, the spring arm 2 returns to its original position, allowing the spring arm 2 to engage with the electronic device, thereby achieving self-locking.

[0058] The negative electrode spring 422 inside the electronic device is connected to the button battery 3, and the button battery 3 deforms the negative electrode spring 422 by squeezing it. When it is necessary to disassemble the button battery compartment, the elastic arm 2 is squeezed, so that the elastic arm 2 is pressed and moves towards the battery bracket 1 to release the self-locking. The elastic force generated by the deformation of the negative electrode spring 422 can push the button battery 3 and the button battery compartment out of the battery insertion port 41 of the electronic device.

[0059] Specifically, such as Figure 2a , Figure 2c and Figure 3a As shown, Figure 3a for Figure 1a The diagram shows a button battery compartment with a button battery fully inserted into an electronic device. One side of the button battery 3 is the positive electrode plane, and the other side has a protrusion structure. The side of the protrusion structure away from the positive electrode plane serves as the negative terminal 31, electrically connected to the positive electrode spring 421. The side of the protrusion structure can serve as the positive terminal 32 of the button battery, electrically connected to the negative electrode spring 422, thereby achieving circuit conduction. Figure 3a As shown, when the button battery 3 is fully inserted into the electronic device, the negative electrode spring 422 is compressed by the button battery 3 and deforms. When the elastic arm 2 is compressed and the battery holder 1 releases its self-locking, the negative electrode spring 422 can push the button battery 3 and the button battery compartment out of the battery insertion port 41 of the electronic device. In other words, when removing the button battery compartment, it is only necessary to manually tighten the elastic arm 2, and the button battery compartment will automatically pop out under the elastic potential energy of the negative electrode spring 422, allowing the button battery compartment to be further removed.

[0060] In some embodiments, such as Figures 1a to 2c As shown, there can be one elastic arm 2, which can be located on either side of the battery holder 1 along the first direction X. Simply squeeze the elastic arm 2 to deform it, releasing the self-locking state of the button battery compartment, and the button battery compartment can be pulled out.

[0061] In some embodiments, there can be two elastic arms 2, which are located on both sides of the battery holder 1 along the first direction X. In this way, when the button battery compartment is pulled out, the elastic arms 2 on both sides of the battery holder 1 are squeezed at the same time, and the two elastic arms 2 deform simultaneously, so that the force on the button battery compartment is balanced, thereby avoiding the tilting caused by the force on one side of the battery holder 1, and making it easier to use.

[0062] See Figure 1a and Figure 2a The groove 11 can be an arc-shaped groove with one side open. The button battery 3 is inserted into the battery holder 1 from the opening position, so that part of the button battery 3 is located on the outside of the battery holder 1, so that the positive terminal 32 of the button battery 3 can be connected with the negative terminal spring 422.

[0063] Of course, the groove 11 can also be a circular groove. The button battery 3 is pressed into the circular groove from the top opening of the circular groove. By adjusting the depth of the circular groove, the protrusion structure of the button battery 3 protrudes outward from the top opening of the circular groove, so that the positive terminal 32 of the button battery 3 can be connected with the negative terminal spring 422.

[0064] Depending on actual needs, the groove 11 can be configured with other structures, as long as it can enable the button battery 3 and the circuit board 42 to form a current loop.

[0065] In some embodiments of this application, the length of the spring-loaded groove 12 along the second direction Y accounts for 85%-95% of the length of the battery holder 1 along the second direction Y; and / or, the width of the spring-loaded groove 12 along the first direction X is 1mm-2mm. Specifically, the length of the spring-loaded groove 12 along the second direction Y can account for 85%, 87%, 90%, 90.6%, 93%, or 95% of the length of the battery holder 1 along the second direction Y; the width of the spring-loaded groove 12 along the first direction X can be 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, or 2mm.

[0066] In this embodiment, the length of the spring-loaded groove 12 along the second direction Y can be set to 90.6% of the length of the battery holder 1 along the second direction Y. Increasing the length of the spring-loaded groove 12 also increases the length of the elastic arm 2. This increases the lever arm length of the elastic arm 2 when it is compressed, effectively reducing the external force required for deformation and thus simplifying its use. The width of the spring-loaded groove 12 can be set to 1.4 mm to provide sufficient deformation space for the elastic arm 2.

[0067] In some implementations of this application, such as Figure 1b , Figure 2b and Figures 3b to 3c As shown, Figure 3b for Figure 3a Rear view; Figure 3c for Figure 1a The diagram shows a button battery compartment with a button battery not fully inserted into the electronic device. A bracket guide groove 13 is provided on the side of the battery holder 1 away from the groove 11, and the bracket guide groove 13 extends along the second direction Y; the opening of the bracket guide groove 13 faces the second direction, and the guide slider 431 inside the electronic device can slide into the bracket guide groove 13.

[0068] In this embodiment, a bracket guide groove 13 is provided on the side of the battery holder 1 away from the groove 11, and one end of the bracket guide groove 13 facing the second direction Y passes through the side wall of the battery holder 1. Thus, when the battery holder 1 is inserted into the electronic device, the end of the battery holder 1 through the bracket guide groove is inserted into the electronic device first, and the guide slider 431 inside the electronic device can slide into the bracket guide groove 13. In this way, the cooperation between the bracket guide groove 13 and the guide slider 431 ensures that the battery holder 1 slides along the extension direction of the guide slider 431, thereby providing guidance for the insertion and removal process of the battery holder 1, avoiding misalignment of the battery holder 1 along the first direction X during insertion and removal, thereby improving the stability between the button battery compartment and the button battery 3, and reducing the probability of poor contact between the button battery 3 and the electronic device.

[0069] In some embodiments, such as Figure 1a , Figure 2a and Figure 3a As shown, a handle groove 14 can be provided on the battery holder 1. When the button battery compartment pops out, the battery holder 1 can be gripped by inserting a finger into the handle groove 14.

[0070] In some implementations of this application, such as Figures 1a to 3c and Figure 4a As shown, Figure 4a for Figure 3a A first-person sectional view. An inclined rib 21 is provided on the side of the elastic arm 2 away from the battery bracket 1; the width of the inclined rib 21 decreases along the second direction Y; after the button battery compartment is inserted into the battery insertion port 41, the orthographic projection of the inclined rib 21 onto the plane containing the bottom surface of the groove 11 is located outside the orthographic projection of the battery insertion port 41 onto the plane containing the bottom surface of the groove 11.

[0071] In this embodiment, the elastic arm 2 can be a straight rod, and an inclined rib 21 is provided on the side of the elastic arm 2 away from the battery bracket 1. The orthographic projection of the inclined rib 21 onto the plane containing the bottom surface of the groove 11 is located outside the orthographic projection of the battery insertion port 41 onto the plane containing the bottom surface of the groove 11. That is, the maximum width of the inclined rib 21 along the first direction X is greater than the width of the battery insertion port 41 along the first direction X.

[0072] During the process of inserting the button battery compartment into the battery insertion port 41, the inner wall of the battery insertion port 41 of the electronic device presses against the inclined rib plate 21, causing the elastic arm 2 to deform toward the spring groove 12 so that the battery bracket 1 can be inserted from the battery insertion port 41.

[0073] When the button battery compartment is fully inserted into the electronic device, the battery insertion port 41 disengages from the inclined rib 21 and no longer presses against it. At this time, the elastic arm 2 can drive the inclined rib 21 to return to its original position under the action of elastic force. The returned inclined rib 21 engages with the inner wall of the electronic device, thereby fixing the button battery compartment inside the electronic device to prevent it from loosening.

[0074] In some embodiments, such as Figure 2c As shown, the thickness of the inclined rib 21 can be less than the thickness of the elastic arm 2. Thus, when the inclined rib 21 is reset, as... Figure 3b As shown, the side of the elastic arm 2 away from the battery bracket 1 can abut against the second limiting part 433 of the battery compartment limiting frame 43 of the electronic device, thereby restricting the movement of the battery bracket 1 along the first direction X, so as to reduce the misalignment of the button battery compartment along the first direction X caused by shaking during the use of the electronic device, and further reduce the probability of poor contact between the button battery and the electronic device during the use of the electronic device.

[0075] In some embodiments of this application, such as Figures 1a to 2b and Figure 4b As shown, Figure 4b for Figure 3b A second-perspective cross-sectional view. A latching part 22 is provided on the side of the elastic arm 2 away from the battery holder 1; the latching part 22 extends in the direction away from the battery holder 1 and is used to latch with the edge of the battery insertion port 41 of the electronic device.

[0076] In this embodiment, a snap-fit ​​part 22 is provided on the side of the elastic arm 2 away from the battery bracket 1. The snap-fit ​​part 22 is snapped into the edge of the battery insertion port 41 to fix the button battery compartment inside the electronic device and prevent the button battery compartment from coming loose.

[0077] Of course, an inclined rib 21 and a latching part 22 can be provided on the elastic arm 2 at the same time. In this case, the width of the latching part 22 along the first direction X can be made smaller than the maximum width of the inclined rib 21 along the first direction X. In this way, when the inclined rib 21 is squeezed and contracted during the insertion of the button battery compartment, the latching part 22 will not interfere with the edge of the battery insertion port 41, so that the button battery compartment can be fully inserted into the electronic device.

[0078] In some implementations of this application, such as Figures 1a to 2bAs shown, a wrench part 23 is provided on the side of the elastic arm 2 away from the battery bracket 1, and extends in the direction away from the battery bracket 1; the wrench part 23 can drive the elastic arm 2 to move toward the spring groove 12 under the action of external force.

[0079] In this embodiment, when removing the button battery compartment, simply turning the lever 23 will move the spring arm 2 toward the spring-loaded groove 12. (See 1a and...) Figure 3d As shown, Figure 3d for Figure 1a The diagram shown is a structural schematic of the button battery compartment with a button battery fully inserted into the electronic device from another perspective. When the button battery compartment is fully inserted into the electronic device, there is a gap between the battery insertion port 41 and the lever portion 23 on both sides along the first direction X. This gap is formed as a latch position 411. When it is necessary to turn the lever portion 23, the lever portion 23 can be turned by inserting a finger into the latch position 411.

[0080] In some implementations of this application, such as Figure 1a and Figure 2a As shown, a battery fixing part 111 protruding outward from the inner sidewall of the groove 11 is provided; the battery fixing part 111 is spaced apart from the bottom surface of the groove 11, and the battery fixing part 111 is used to cooperate with the bottom surface of the groove 11 to clamp the button battery 3.

[0081] In this embodiment, a battery fixing part 111 is provided on the inner sidewall of the groove 11. When the button battery 3 is installed in the groove 11, the positive electrode plane of the button battery 3 is in contact with the bottom surface of the groove 11, and the side of the button battery 3 away from the positive electrode plane abuts against the battery fixing part 111, thereby restricting the displacement of the button battery 3 along the depth direction of the groove 11, thereby improving the situation of the button battery 3 becoming loose, and further reducing the probability of poor contact between the button battery 3 and the circuit board 42.

[0082] This application also provides an electronic device, which can be a PLC (Programmable Logic Controller) or a servo controller, or other electronic devices that require a coin cell battery as a power source. Figures 3a to 3c As shown, the electronic device includes: a device housing 4 and a button battery compartment of any of the above embodiments; the device housing 4 includes: a battery insertion port 41 and a circuit board 42, the circuit board 42 including a negative electrode spring 422; the button battery compartment can be inserted into the device housing 4 through the battery insertion port 41.

[0083] In this embodiment, the button battery compartment can be inserted into the electronic device through the battery insertion port 41 of the device housing 4, so that the positive terminal 32 of the button battery 3 is connected to the negative terminal spring 422 of the circuit board 42, and the negative terminal 31 of the button battery 3 is in contact with the positive terminal spring 421 of the circuit board 42, thereby forming a conductive current loop.

[0084] The battery holder 1 of the button battery compartment includes a recess 11. For example... Figures 2a to 2c As shown, the button battery 3 can be installed in the groove 11. The positive electrode plane of the button battery 3 can contact the bottom surface of the groove 11, and the bottom surface of the groove 11 can support the button battery 3, increasing the contact area between the positive electrode plane of the button battery 3 and the battery holder 1, improving the stability between the two, and thus reducing the probability of poor contact between the button battery 3 and the electronic device.

[0085] Furthermore, the button battery compartment is equipped with a spring arm 2. During the insertion of the button battery compartment into the electronic device, the spring arm 2 can deform towards the spring-loaded groove 12 to allow the button battery compartment to be inserted into the electronic device. After the battery holder 1 is inserted into the electronic device, the spring arm 2 returns to its original position, allowing the spring arm 2 to engage with the electronic device, thereby achieving self-locking.

[0086] In some implementations of this application, such as Figure 3a and Figure 4a As shown, the negative electrode spring 422 is Y-shaped, and the elastic force generated by the deformation of the free end of the negative electrode spring 422 can push the button battery compartment out of the battery insertion port 41.

[0087] In this embodiment, the main body of the Y-shaped negative electrode spring 422 is fixedly connected to the circuit board 42. The end of the main body facing the battery insertion port 41 has a free end of the negative electrode spring 422, consisting of two springs extending obliquely towards the battery insertion port 41. When the button battery 3 enters the electronic device, the positive terminal 32 of the button battery 3 presses against the free end, causing the free end to deform and store force. At this time, the latch between the battery holder 1 and the electronic device is released, the free end resets, and the resulting elastic force can push the button battery 3 and the button battery compartment out of the battery insertion port 41 from the electronic device.

[0088] In some implementations of this application, such as Figures 3a to 3c As shown, the device housing 4 also includes a battery compartment limiting frame 43; an inclined rib 21 is provided on the side of the elastic arm 2 away from the battery bracket 1; the battery compartment limiting frame 43 includes: a first limiting part 432 extending along the first direction X and a second limiting part 433 disposed at both ends of the first limiting part 432 and extending along the second direction Y; the first limiting part 432 can abut against the edge of the battery bracket 1 facing the second direction Y, for limiting the movement of the battery bracket 1 along the second direction Y; the second limiting part 433 can abut against both sides of the battery bracket 1 along the first direction X, for limiting the movement of the battery bracket 1 along the first direction X.

[0089] In this embodiment, the battery compartment limiting frame 43 of the device housing 4 can limit the button battery compartment. For details, see... Figure 3aThe first limiting portion 432 of the battery compartment limiting frame 43 can abut against the edge of the battery holder 1 facing the second direction Y. This limits the maximum distance the battery holder 1 can move along the second direction Y, thus preventing damage to the negative electrode spring 422 caused by excessive insertion depth of the button battery compartment. The second limiting portion 433 of the battery compartment limiting frame 43 can abut against both sides of the battery holder 1 along the first direction X. This limits the displacement of the battery holder 1 along the first direction X, thereby reducing the misalignment of the battery holder 1 along the first direction X during insertion and removal.

[0090] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
