Description

Technical Field

[0001] This application belongs to the field of battery bracket design technology, specifically relating to a battery bracket assembly and electronic device. Background Technology

[0002] As a fixing structure used to secure batteries to the main body of electronic devices, battery brackets not only prevent batteries from loosening or falling off during use, but also ensure battery safety, prevent damage from external forces, and improve heat conduction and dissipation to avoid overheating affecting battery performance and lifespan.

[0003] Currently, the following problems exist in the process of fixing the battery bracket to the main body of the device: When one end of the connector is inserted into the mounting hole of the battery bracket, because the diameter of the mounting hole is larger than the diameter of the connector, the connector is in an unrestricted state in the mounting hole and can tilt or shake freely up, down, left, and right. This will cause the connector to fail to accurately position the corresponding connection hole when connecting to the main body of the device, and there is a risk that the connector will be misaligned or off-center. Utility Model Content

[0004] The purpose of this application is to provide a battery bracket assembly and an electronic device that can solve the problem of the connectors being tilted or misaligned during the installation of the battery bracket onto the main body of the electronic device.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide a battery bracket assembly, including a battery bracket, a connector, and a positioning member. The battery bracket includes a connected bracket body and a connecting protrusion. The connecting protrusion is disposed on the outer peripheral surface of the bracket body and has a mounting hole. A first end of the connector is used to pass through the mounting hole and connect to the device body of an electronic device. The positioning member is an elastically deformable structure and is disposed on the wall of the mounting hole. The positioning member and the connector are positioned and engaged so that the central axis of the connector is parallel to the central axis of the mounting hole.

[0006] Optionally, the mounting hole includes a first hole segment and a second hole segment that are connected to each other, the diameter of the first hole segment is larger than the diameter of the second hole segment, and the positioning element is disposed on the hole wall of the first hole segment. Optionally, the mounting hole further includes a third hole segment, which is disposed on the side of the second hole segment opposite to the first hole segment. The third hole segment is connected to the second hole segment, and the diameter of the third hole segment is larger than the diameter of the second hole segment. The first end of the connector is used to pass through the third hole segment, the second hole segment and the first hole segment in sequence to connect with the device body, and the second end of the connector is located inside the third hole segment. Optionally, the positioning element is a ring structure. Optionally, the positioning member has a notch on its inner edge, and the notch extends along the direction of the inner edge of the positioning member toward the outer edge.

[0007] Optionally, the number of notches is at least two, and each notch is arranged sequentially at intervals along the circumference of the positioning member, and each notch is evenly distributed along the circumference of the positioning member.

[0008] Optionally, the notch is an arc-shaped structure. Optionally, in the direction of extension from the inner edge to the outer edge of the positioning member, the width of the notch first gradually increases and then gradually decreases.

[0009] Optionally, in the direction of extension from the inner edge to the outer edge of the positioning member, the ratio of the depth of the notch to the width of the positioning member is 0.5 to 0.75. Secondly, embodiments of this application also provide an electronic device, including a device body, a battery, and the aforementioned battery bracket assembly, wherein the battery is disposed on the bracket body of the battery bracket, and the first end of the connector passes through the mounting hole and is connected to the device body.

[0010] In this embodiment, a positioning element is provided on the inner wall of the mounting hole of the battery holder. The first end of the connector is inserted into the mounting hole, and before the first end of the connector is connected to the main body of the electronic device, the positioning element contacts the circumferential surface of the connector. The two elements engage in a positioning fit, restricting the connector within the mounting hole and placing it in a pre-locked state. This prevents the connector from tilting or wobbling arbitrarily, ensuring that the central axis of the connector is parallel to the central axis of the mounting hole. Consequently, when the connector is connected to the main body of the device, it can be accurately positioned to the corresponding connecting hole on the main body, preventing the connector from being tilted or misaligned. Therefore, this embodiment solves the problem of connector tilting or misalignment during the installation of the battery holder onto the main body of the electronic device.

Detailed Implementation

[0012] 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, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0013] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] The battery bracket assembly and electronic device provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0015] like Figures 1 to 6 As shown in the figure, this application embodiment provides a battery bracket assembly, which includes a battery bracket 100, a connector 200 and a positioning member 300. The battery bracket 100 is used to fix the battery and prevent the battery from shaking, thereby ensuring the safety and reliability of the battery. At the same time, the battery bracket can provide good heat dissipation performance for the battery.

[0016] The battery bracket 100 includes a connected bracket body 110 and a connecting protrusion 120. The connecting protrusion 120 is disposed on the outer peripheral surface of the bracket body 110 and has a mounting hole 121. The first end of the connector 200 is used to pass through the mounting hole 121 of the connecting protrusion 120 and connect to the device body of the electronic device. Optionally, the connector 200 can be a screw, bolt, etc., in which case the connector 200 and the device body can be connected by threads. The specific structure of the connector 200 is not limited in this embodiment. The positioning member 300 is an elastically deformable structure. Optionally, the positioning member 300 can be a polyurethane, polyethylene, elastic steel, etc., and this embodiment is not specifically limited in this respect. The positioning member 300 is disposed on the wall of the mounting hole 121. The positioning member 300 and the connector 200 are positioned and engaged so that the central axis of the connector 200 is parallel to the central axis of the mounting hole 121. That is, the positioning member 300 and the connector 200 are positioned and engaged so that the connector 200 is perpendicular to the plane where the connecting protrusion 120 is located.

[0017] In this embodiment, a positioning member 300 is provided on the inner wall of the mounting hole 121 of the battery holder 100. The first end of the connector 200 is inserted into the mounting hole 121. Before the first end of the connector 200 is connected to the main body of the electronic device, the positioning member 300 contacts the circumferential surface of the connector 200, and the two engage in a positioning fit. This restricts the connector 200 within the mounting hole 121, placing it in a pre-locked state. This prevents the connector 200 from tilting or wobbling arbitrarily, ensuring that the central axis of the connector 200 is parallel to the central axis of the mounting hole 121. Consequently, when the connector 200 is connected to the main body of the device, it can be accurately positioned to the corresponding connection hole on the main body, preventing the connector 200 from being tilted or misaligned. Therefore, this embodiment solves the problem of the connector 200 tilting or misaligning during the installation of the battery holder 100 to the main body of the electronic device.

[0018] It should be noted that in the above embodiment, during the process of inserting the first end of the connector 200 into the mounting hole 121, the positioning member 300 deforms so that the threaded section of the connector 200 can pass smoothly through the mounting hole 121.

[0019] In addition, in the above embodiments, when the positioning member 300 and the connector 200 are positioned and engaged, it can prevent the connector 200 from shaking and making abnormal noise in the mounting hole 121 before it is connected to the main body of the device. Optionally, the diameter of the mounting hole 121 can remain unchanged in the extension direction of the central axis of the mounting hole 121; or, in other optional embodiments, the mounting hole 121 includes a first hole segment 121a and a second hole segment 121b that are connected, the diameter of the first hole segment 121a is larger than the diameter of the second hole segment 121b, that is, the mounting hole 121 is a stepped hole, and the positioning member 300 is disposed on the hole wall of the first hole segment 121a. By setting the diameter of the first hole segment 121a to be larger, the accommodating space of the first hole segment 121a is increased, so as to facilitate the placement of the positioning member 300. Of course, the positioning member 300 can also be disposed on the hole wall of the second hole segment 121b.

[0020] In a further optional embodiment, the mounting hole 121 further includes a third hole segment 121c, which is disposed on the side of the second hole segment 121b away from the first hole segment 121a. The third hole segment 121c is connected to the second hole segment 121b. That is, the mounting hole 121 includes the third hole segment 121c, the second hole segment 121b and the first hole segment 121a connected in sequence. The diameter of the third hole segment 121c is larger than the diameter of the second hole segment 121b to form a limiting end face 121d. That is, the mounting hole 121 can be in the shape of an "I". The first end of the connector 200 is used to pass through the third hole segment 121c, the second hole segment 121b and the first hole segment 121a in sequence to connect with the main body of the equipment. The second end of the connector 200 is provided with a limiting flange 210, which is located in the third hole segment 121c. The limiting flange 210 and the limiting end face 121d are engaged in an axial limiting fit with the connector 200. In this design, the limiting flange 210 of the connector 200 and the positioning member 300 are located on opposite sides of the second hole segment 121b, which avoids interference between them. Of course, the third hole segment 121c can also be located on the side of the first hole segment 121a away from the second hole segment 121b, or the third hole segment 121c can be omitted. Optionally, the connector 200 includes a threaded section 220 and a smooth section 230 connected together. The threaded section 220 is used to sequentially pass through the third hole section 121c, the second hole section 121b, and the first hole section 121a to be threadedly connected to the main body of the device. The positioning member 300 is positioned and engaged with the smooth section 230. The limiting flange 210 is disposed at the end of the smooth section 230 away from the threaded section 220. During the threaded connection between the threaded section 220 and the main body of the device, the limiting flange 210 is engaged with the limiting end face 121d to limit the connection, thereby preventing the connector 200 from continuing to move relative to the battery bracket 100. Optionally, the smooth section 230 may be provided with an annular reinforcing part. In the direction of extension of the smooth section 230 to the threaded section 220, the cross-sectional area of ​​the annular reinforcing part gradually decreases, that is, the annular reinforcing part has a conical structure. The maximum cross-section of the annular reinforcing part is connected to the limiting flange 210, thereby enhancing the structural strength of the connection between the smooth section 230 and the limiting flange 210. Correspondingly, the shape of the second hole section 121b is adapted to the shape of the smooth section 230.

[0021] Optionally, the diameter of the third hole segment 121c can be larger than the diameter of the first hole segment 121a. In this case, the area of ​​the limiting end face 121d is larger, and the end face of the limiting flange 210 can be increased accordingly to increase the contact area between the limiting flange 210 and the limiting end face 121d. Of course, the diameter of the third hole segment 121c is also less than or equal to the diameter of the first hole segment 121a. This application embodiment does not impose specific limitations on this.

[0022] Optionally, the positioning element 300 can be an arc-shaped structure; or, in other optional embodiments, the positioning element 300 is an annular structure. In this case, when the positioning element 300 and the connecting element 200 are positioned and engaged, the contact area between the positioning element 300 and the connecting element 200 is large. This can disperse the force on the connecting element 200, making the force exerted by the positioning element 300 on the connecting element 200 more uniform, thereby improving the positioning stability of the positioning element 300. Furthermore, when the positioning element 300 is an annular structure, there is a certain gap between the circumferential surface of the connecting element 200 and the inner surface of the mounting hole 121 in the circumferential direction of the connecting element 200. This can prevent the connecting element 200 from contacting the inner surface of the mounting hole 121 during the threaded connection between the connecting element 200 and the main body of the equipment, thus preventing the connecting element 200 from rotating relative to the inner wall of the mounting hole 121.

[0023] Optionally, when the positioning member 300 is an annular structure, the central axis of the connecting member 200 can coincide with the central axis of the mounting hole 121. In this case, the width of the positioning member 300 in its circumferential direction remains basically unchanged, so that the stress on its inner edge is more uniform when the positioning member 300 deforms.

[0024] In another optional embodiment, the positioning member 300 has a notch 310 along its inner edge, extending outward from the inner edge. Since the positioning member 300 is an elastically deformable structure, stress is concentrated at its inner edge when deformation occurs. Therefore, by creating the notch 310, the stress concentration area is changed, concentrating stress at the root of the notch 310, thereby reducing stress at the inner edge of the positioning member 300 and preventing premature failure due to material embrittlement, thus extending the service life of the positioning member 300. Of course, the notch 310 can also be omitted.

[0025] In a further optional embodiment, the number of notches 310 can be one, or the number of notches 310 can be at least two, with each notch 310 arranged sequentially at intervals along the circumference of the positioning member 300, and the notches 310 being evenly distributed along the circumference of the positioning member 300. By providing multiple notches 310, the stress at the inner edge of the positioning member 300 under deformed state can be further reduced, and the stress at the root of the notch 310 can be dispersed to avoid stress concentration, thereby further improving the service life of the positioning member 300.

[0026] Optionally, the notch 310 can be a V-shaped structure, a rectangular structure, etc.; or, in other optional embodiments, the notch 310 is an arc-shaped structure. Since the curvature of the arc-shaped structure is relatively small, stress concentration can be avoided, and the stress at the root of the notch 310 can be dispersed to the surrounding area, thereby further extending the service life of the positioning member 300. Optionally, the width of the notch 310 can gradually decrease in the direction of extension from the inner edge to the outer edge of the positioning member 300; or, in a further optional embodiment, the width of the notch 310 first gradually increases and then gradually decreases in the direction of extension from the inner edge to the outer edge of the positioning member 300. This can ensure that the rate of curvature change at the root of the notch 310 is small, so as to disperse the stress at the root of the notch 310, and can also increase the contact area between the inner edge of the positioning member 300 and the connector 200, thereby improving the positioning stability between the positioning member 300 and the connector 200.

[0027] In another optional embodiment, the ratio of the depth of the notch 310 to the width of the positioning member 300 in the direction extending from the inner edge to the outer edge of the positioning member 300 is 0.5 to 0.75. If the ratio of the depth of the notch 310 to the width of the positioning member 300 in the direction extending from the inner edge to the outer edge of the positioning member 300 is too small, then the depth of the notch 310 is small. In this case, the root of the notch 310 is close to the inner edge of the positioning member 300, which easily leads to stress concentration and damage at the inner edge when the positioning member 300 deforms. If the ratio of the depth of the notch 310 to the width of the positioning member 300 is too large, then the depth of the notch 310 is large. In this case, the root of the notch 310 is close to the outer edge of the positioning member 300, and the structural strength at the root of the notch 310 is weak, which easily leads to deformation of the positioning member 300. The root of the time-varying notch 310 is at risk of cracking or even breaking. Therefore, in the direction of extension from the inner edge to the outer edge of the positioning member 300, the ratio of the depth of the notch 310 to the width of the positioning member 300 is 0.5 to 0.75. This can prevent the root of the notch 310 from being close to the inner edge of the positioning member 300, which would cause damage to the inner edge of the positioning member 300 due to stress concentration. It can also prevent the root of the notch 310 from being close to the outer edge of the positioning member 300, which would result in a weaker structural strength at the root of the notch 310 and the risk of cracking or even breaking at the root of the notch 310. This will improve the service life of the positioning member 300.
