Description

Technical Field

[0001] This utility model relates to the field of mounting brackets, specifically to a mounting bracket for a battery pack. Background Technology

[0002] Battery packs, as the core carriers for energy storage and output, have a wide range of applications, including but not limited to electric bicycles, electric scooters, electric bicycles, and energy storage power stations, becoming a key component of smart energy systems. With the increasing complexity of application scenarios, higher demands are placed on the reliability and adaptability of battery pack mounting devices. Among these, the mounting bracket, as a crucial component for achieving the mechanical connection between the battery pack and the main equipment, is related to both safety and user experience.

[0003] Battery pack mounting brackets typically consist of a main body, a positioning and holding structure, and a shock-absorbing component. They secure the battery pack to the equipment frame using bolts, snap-fit ​​mechanisms, or other methods. Taking an electric bicycle battery swapping system as an example, the mounting bracket needs to enable quick insertion and removal of the battery pack, precise positioning, and stable locking within a limited space, while also being compatible with different battery pack specifications.

[0004] However, existing battery pack mounting systems still have significant drawbacks. Most existing mounting systems have simple designs, such as single-point snap-fit ​​or rigid connections, which makes them prone to displacement and loosening under complex operating conditions such as vibration and impact. Especially in scenarios with frequent bumps, the reliability of the connection between the mounting system and the battery pack decreases significantly, causing the battery pack to easily shift and vibrate, affecting its safety and practicality. Furthermore, existing mounting systems do not allow for quick locking and limiting of the battery pack or easy disassembly, affecting the stability and reliability of the battery pack's fixation. Therefore, there is an urgent need for a mounting system with a self-locking limiting function to improve the stability and reliability of battery pack installation. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned defects and provide a fixing seat for a battery pack, so as to solve the technical problem in the background art of how to make the battery pack quickly locked and conveniently disassembled, thereby improving the stability and reliability of the connection between the battery pack and the fixing seat.

[0006] The objective of this utility model is achieved through the following means:

[0007] A mounting base for a battery pack includes a base with a mounting groove for mating and inserting a battery pack. Multiple limiting blocks are arranged on the inner wall of the mounting groove. One side of the base has a clearance slot communicating with the mounting groove, and a locking spring is provided within the clearance slot. A mounting portion for connecting the locking spring is provided on the side of the base near the clearance slot. The bottom of the mounting portion has a clearance portion communicating with the clearance slot. One end of the locking spring extends outward from the base by bending through the clearance portion, forming a press-to-unlock portion. The other end of the locking spring extends obliquely towards the mounting groove by bending, forming an elastic portion. The end of the elastic portion extending towards the mounting groove is bent to form a locking portion for clamping and wedging the battery pack. The elastic portion can continuously apply a locking force to the locking portion.

[0008] When one end of the battery pack is inserted into the mounting groove, the outer side of the battery pack is pressed against the locking part of the locking spring, causing the battery pack to be inserted into the mounting groove. The elastic part drives the locking part to apply pressure to the outer side of the battery pack, and the locking part wedges and locks the battery pack.

[0009] When pressure is applied to the unlocking part, the elastic part causes the locking part to tilt up, causing the locking part to release the lock on the battery pack.

[0010] Furthermore, as described above, the limiting blocks are spaced apart and arranged on the inner wall of the mounting groove, and the ends of the limiting blocks are formed with arc-shaped chamfers. The limiting blocks are used to hold and limit the outer surface of the battery pack.

[0011] The limiting blocks are spaced apart on the inner wall of the mounting groove, which can hold and limit the outer surface of the battery pack from multiple positions. This can effectively prevent the battery pack from shifting or loosening under complex working conditions such as vibration and impact. Especially in frequent bumpy scenarios, it can improve the reliability of the connection between the battery pack and the mounting base, reduce battery pack offset and shaking, and ensure the safety and practicality of the battery pack. The ends are formed with arc-shaped chamfers to facilitate the insertion of the battery pack into the mounting groove and avoid scratching the battery pack.

[0012] Furthermore, as described above, the interior of the mounting groove is provided with protruding positioning blocks, and multiple positioning blocks are provided, which are distributed in a circumferential array.

[0013] Multiple positioning blocks are arranged in a circular array inside the mounting groove, which can more accurately position the battery pack, ensuring that the battery pack is accurately positioned in the mounting groove and preventing the battery pack from shifting after installation. This further enhances the stability and reliability of the connection between the battery pack and the mounting base, and ensures that the battery pack is firmly fixed even under complex working conditions.

[0014] Furthermore, the locking spring is bent to form a positioning part for installation. The side of the positioning part is provided with a protruding positioning protrusion. The mounting part is provided with a positioning hole for mating and inserting the connecting block. The locking spring is mated with the clearance groove through the positioning part, and the positioning protrusion is inserted and assembled with the positioning hole.

[0015] The locking spring is matched with the positioning part and the clearance groove, and the positioning protrusion is matched with the positioning hole. This allows the locking spring to be accurately installed in the designated position, ensuring the positional accuracy of the locking spring after installation. This enables the locking spring to perform its locking function normally, improves the stability and reliability of battery pack locking, and avoids locking failure due to installation deviation of the locking spring.

[0016] Furthermore, as described above, the mounting part is provided with a limiting hole that communicates with the positioning hole, and a nut screw for pressing and limiting the positioning protrusion is inserted in the limiting hole.

[0017] The nut screw passes through the limiting hole to press and limit the positioning protrusion, which can further fix the position of the locking spring, prevent the locking spring from loosening or shifting during use, ensure that the locking spring continuously and stably locks the battery pack, and improve the stability and reliability of the connection between the battery pack and the mounting base.

[0018] Furthermore, as described above, the inner side of the mounting groove is provided with an anti-slip part, and an anti-slip strip is adhered to the anti-slip part. The anti-slip strip is composed of an anti-slip silicone pad or an anti-slip fixing cotton.

[0019] The inner side of the mounting groove is equipped with an anti-slip part and an anti-slip strip is attached. The anti-slip silicone pad or anti-slip fixing cotton has good anti-slip performance, which can increase the friction between the battery pack and the mounting groove, effectively prevent the battery pack from sliding under vibration, impact and other conditions, further improve the stability and reliability of the connection between the battery pack and the mounting base, and ensure the safe fixing of the battery pack under various working conditions.

[0020] Furthermore, as described above, the base is provided with fixing holes for fixed installation, and the side of the base is provided with a connecting part for positioning and installation.

[0021] The base has mounting holes for easy installation of the mounting bracket on other equipment or structures; the side has a positioning connection part for precise positioning during installation, ensuring accurate installation of the mounting bracket and guaranteeing the stability of the connection between the mounting bracket and other components, thereby improving the stability and reliability of the entire system for securing the battery pack.

[0022] Furthermore, as described above, the interior of the mounting groove is provided with a contact spring for contacting the polarity end of the battery pack, and the contact spring extends obliquely toward the opening end of the mounting groove by bending.

[0023] The mounting groove contains a contact spring that extends at an angle towards the open end. When the battery pack is inserted into the mounting groove, the contact spring can make good contact with the polarity end of the battery pack, ensuring a stable and reliable electrical connection between the battery pack and the mounting base. The angled extension design facilitates smooth contact between the battery pack and the contact spring when it is inserted, and also ensures that the contact spring and the polarity end of the battery pack always maintain good contact when the battery pack is subjected to vibration or other influences.

[0024] The beneficial effects of this utility model are as follows: Multiple limiting blocks can restrict the battery pack from multiple positions, effectively preventing displacement and loosening of the battery pack under complex working conditions such as vibration and impact, as well as frequent bumpy scenarios. This improves the reliability of the connection between the battery pack and the mounting base. When one end of the battery pack is inserted into the mounting groove, the outer side of the battery pack is pressed against the locking part of the locking spring. The elastic part drives the locking part to apply pressure to the outer side of the battery pack, creating a wedge-tight self-locking effect. This ensures that the battery pack is automatically and securely locked after insertion, further improving the stability of the battery pack. When pressure is applied to the unlocking part, the elastic part causes the locking part to tilt upwards, releasing the locking part from the battery pack. Through the limiting action of the limiting blocks and the wedge-tight self-locking and convenient unlocking functions of the locking spring, the stability and reliability of the battery pack installation are ensured, and quick locking and convenient disassembly are achieved.

[0038] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer, the following describes the solution in further detail with reference to the accompanying drawings and embodiments.

[0039] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this scheme and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Example 1

[0041] In this embodiment, refer to Figures 1-5The specific implementation of a battery pack mounting base includes a base 100. The base 100 has a mounting groove 101 for mating and inserting the battery pack. Multiple limiting blocks 102 are arranged on the inner wall of the mounting groove 101. One side of the base 100 has a clearance slot 103 communicating with the mounting groove 101. A locking spring 200 is provided within the clearance slot 103. The side of the base 100 near the clearance slot 103 has a mounting portion 104 for connecting the locking spring 200. The bottom of the mounting portion 104... The base is provided with a clearance portion 105 that communicates with the clearance slot 103. One end of the locking spring 200 extends outward from the base 100 through the clearance portion 105 by bending, and forms a press-to-unlock portion 201. The other end of the locking spring 200 extends obliquely towards the mounting groove 101 by bending, and forms an elastic portion 202. The end of the elastic portion 202 that extends towards the mounting groove 101 is bent to form a locking portion 203 for holding and wedge-tightening the battery pack. The elastic portion 202 can continuously apply a locking force to the locking portion 203.

[0042] When one end of the battery pack is inserted into the mounting groove 101, the outer side of the battery pack is pressed against the locking part 203 of the locking spring 200, so that the battery pack is inserted into the mounting groove 101. The elastic part 202 drives the locking part 203 to apply pressure to the outer side of the battery pack, and the locking part 203 wedges and locks the battery pack.

[0043] When pressure is applied to the pressing unlocking part 201, the elastic part 202 causes the locking part 203 to tilt upwards, causing the locking part 203 to release its lock on the battery pack. This allows the battery pack to be easily unlocked simply by applying pressure to the pressing unlocking part when it needs to be removed, making the operation simple and convenient and solving the problem of the existing fixing base making it difficult to easily remove the battery pack.

[0044] Specifically, in this embodiment, the locking spring 200 is formed by bending in sequence to form a pressing part, a positioning part 205, a supporting part 204, an elastic part 202 and a locking part 203. The positioning part 205 is provided with a protrusion on the side near the pressing part to form a positioning protrusion 206. In this embodiment, the locking spring 200 is integrally formed.

[0045] The limiting blocks 102 are spaced apart and arranged on the inner wall of the mounting groove 101. The ends of the limiting blocks 102 are formed with arc-shaped chamfers 106. The limiting blocks 102 are used to hold and limit the outer surface of the battery pack.

[0046] Limiting blocks 102 are spaced apart on the inner wall of the mounting groove 101, which can hold and limit the outer surface of the battery pack from multiple positions. This can effectively prevent the battery pack from shifting or loosening under complex working conditions such as vibration and impact. Especially in frequent bumpy scenarios, it can improve the reliability of the connection between the battery pack and the mounting base, reduce battery pack offset and shaking, and ensure the safety and practicality of the battery pack. The end forms an arc-shaped chamfer 106, which facilitates the insertion of the battery pack into the mounting groove 101 and avoids scratching the battery pack.

[0047] Specifically, in this embodiment, the mounting groove 101 is a circular hole, and four limiting blocks 102 are arranged in a circumferential array on the inner wall of the mounting groove 101. The limiting blocks 102 squeeze the battery pack to generate friction locking, thereby locking and fixing the battery pack.

[0048] The mounting groove 101 is internally provided with protruding positioning blocks 107. Multiple positioning blocks 107 are arranged in a circular array. Specifically, in this embodiment, four positioning blocks 107 are arranged in a circular array inside the mounting groove 101. This allows for more precise positioning of the battery pack, ensuring it is accurately placed within the mounting groove 101 and preventing positional shifts after installation. This further enhances the stability and reliability of the connection between the battery pack and the mounting base, ensuring a secure fixation even under complex working conditions.

[0049] The locking spring 200 has a positioning part 205 for installation formed by bending. The side of the positioning part 205 is provided with a protruding positioning protrusion 206. The mounting part 104 has a positioning hole 108 for mating and inserting the connecting block. The locking spring 200 is mated with the clearance slot 103 through the positioning part 205, and the positioning protrusion 206 is inserted and assembled with the positioning hole 108.

[0050] The locking spring 200 is paired with the clearance slot 103 through the positioning part 205, and the positioning protrusion 206 is inserted and paired with the positioning hole 108. This can accurately install the locking spring 200 into the designated position, ensure the positional accuracy of the locking spring 200 after installation, enable the locking spring 200 to perform its locking function normally, improve the stability and reliability of battery pack locking, and avoid locking failure due to installation deviation of the locking spring 200.

[0051] The mounting part 104 is provided with a limiting hole 109 that communicates with the positioning hole 108. A nut screw 300 for pressing and limiting the positioning protrusion is inserted in the limiting hole 109.

[0052] The 300 screw passes through the limiting hole 109 to press and limit the positioning protrusion, which can further fix the position of the locking spring 200, prevent the locking spring 200 from loosening or shifting during use, ensure that the locking spring 200 continuously and stably locks the battery pack, and improve the stability and reliability of the connection between the battery pack and the mounting base.

[0053] An anti-slip part 110 is provided on the inner side of the mounting groove 101. An anti-slip strip 400 is adhered to the anti-slip part 110. The anti-slip strip 400 is made of an anti-slip silicone pad or an anti-slip fixing cotton.

[0054] An anti-slip part 110 is provided on the inner side of the mounting groove 101 and an anti-slip strip 400 is attached thereon. The anti-slip silicone pad or anti-slip fixing cotton has good anti-slip performance, which can increase the friction between the battery pack and the mounting groove 101, effectively prevent the battery pack from sliding under vibration, impact and other conditions, further improve the stability and reliability of the connection between the battery pack and the fixing seat, and ensure the safe fixing of the battery pack under various working conditions.

[0055] Specifically, in this embodiment, the locking spring 200 and the anti-slip strip 400 are arranged opposite to each other.

[0056] The base 100 has fixing holes 111 for fixed installation, and the side of the base 100 has a connecting part 112 for positioning installation. The fixing holes 111 on the base 100 facilitate the fixing of the mounting bracket to other equipment or structures; the connecting part 112 on the side allows for precise positioning when installing the mounting bracket, ensuring accurate installation and guaranteeing the stability of the connection between the mounting bracket and other components, thereby improving the stability and reliability of the entire system in fixing the battery pack.

[0057] In some embodiments, the battery pack may be a circular or rectangular structure, and the mounting groove 101 is configured to match the outer contour of the battery pack.

[0058] Specifically, the mounting bracket in this embodiment is applicable to the electric bicycle field. The battery pack not only provides power but also achieves a "vehicle-battery separation" battery swapping mode through its detachable design, promoting the formation of an efficient and convenient energy supply network. Therefore, by setting a mounting bracket with self-locking for easy installation and removal, it can be used for quick locking and installation / removal of the battery in electric bicycles. Under the complex working conditions of frequent starting and stopping, vibration, and impact of electric bicycles, as well as frequent bumpy scenarios, it effectively prevents the battery pack from shifting or loosening, avoids battery pack deviation and shaking, improves the reliability of the connection between the battery pack and the mounting bracket, and ensures the safety and practicality of the battery pack.

[0059] The specific operating principle in this embodiment is as follows:

[0060] When one end of the battery pack is inserted into the mounting groove 101, the outer side of the battery pack is pressed against the locking part 203 of the locking spring 200. Simultaneously, the elastic part 202 drives the locking part 203 to apply pressure to the outer side of the battery pack, causing the locking part 203 to wedge and self-lock, automatically and securely locking the battery pack after insertion. Anti-slip pads are adhered to the locking part 203, further improving the stability of the battery pack and protecting it from deformation. When the battery pack reaches the limit of the mounting groove 101, four limit blocks 102 and four positioning blocks 107 restrict the battery pack from multiple positions, further ensuring the stability and safety of the lithium battery installation. The adhesive anti-slip fixing cotton shell provides wrapping protection and anti-slip properties for the battery pack, effectively preventing displacement and loosening under complex working conditions such as vibration and impact, as well as frequent bumpy scenarios, thus improving the reliability of the connection between the battery pack and the mounting base.

[0061] When pressure is applied to the pressing unlocking part 201, the elastic part 202 causes the locking part 203 to tilt up, causing the locking part 203 to release the lock on the battery pack. At this time, the battery pack can be easily removed manually. Through the limiting action of the limiting block 102 and the wedging self-locking and easy unlocking functions of the locking spring 200, the stability and reliability of the battery pack installation are ensured, and quick locking and easy removal can be achieved.

[0062] Example 2

[0063] In this embodiment, refer to Figures 6-7 The difference between this embodiment and embodiment one is that: the mounting groove 101 is provided with a contact spring 500 for contacting the polarity end of the battery pack, and the contact spring 500 extends obliquely towards the opening end of the mounting groove 101 by bending. In this embodiment, the side of the base 100 is provided with an output terminal 700 that is electrically connected to the contact spring 500.

[0064] Specifically, the mounting base can be directly used to support and hold the cylindrical lithium battery 600. For example, it is used to fix the 18650 cylindrical lithium battery 600. The contact spring 500 can be used for electrical contact. The contact spring 500 is provided in the mounting groove 101 and extends obliquely towards the open end. When the battery pack is inserted into the mounting groove 101, the contact spring 500 can make good contact with the polar end of the battery pack, ensuring a stable and reliable electrical connection between the battery pack and the mounting base. The oblique extension design facilitates smooth contact between the battery pack and the contact spring 500 when inserted, and also ensures that the contact spring 500 and the polar end of the battery pack always maintain good contact when the battery pack is affected by vibration or other factors.
