[0024] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0026] Please see Figure 1-4This utility model discloses a battery pull-out bracket, comprising: a battery compartment 1 on which a battery block 4 is installed; a sliding rail 3 for extension and movement is installed on the outer side of the battery compartment 1, and a sliding groove 11 is provided on the inner side of the battery compartment 1; a guide rod 5; the guide rod 5 slides along the sliding groove 11, and a limiting member 6 for clamping and fixing the battery block 4 is installed on the outer side of the guide rod 5; and a return spring 7; the return spring 7 is installed between the guide rod 5 and the limiting member 6, and the return spring 7 clamps the limiting member 6 relative to the battery compartment 1 by means of the elastic force of the extension.

[0027] Please see Figure 2 A sliding groove 11 is formed in the center of the inner wall of the battery compartment 1 near the slide rail 3 and extends through the battery compartment 1. The sliding groove 11 is parallel to the slide rail 3. A fixing groove 12 is formed on the inner wall of the battery compartment 1 near the slide rail 3. The fixing grooves 12 are symmetrically distributed with the sliding groove 11 as the origin. The battery block 4 is installed inside the fixing groove 12. The position and direction of the sliding groove 11 ensure that the guide rod 5 moves along the sliding groove 11 in the same direction as the pull-out of the battery compartment 1. The fixing groove 12 provides a clear installation position for the battery block 4, ensuring the stability of the battery block 4 placed in the battery compartment 1. Compared to the multi-point fixing of bolts, this slot-type positioning simplifies the installation and positioning process of battery block 4. The orientation of the fixing slot 12 is parallel to the orientation of the slide 11, and the two do not conflict with each other. The orientation of the fixing slot 12 limits the installation direction of battery block 4. Battery block 4 can be installed parallel to slide 11 and, together with the limiting member 6, forms a better clamping force, increasing the stability of battery block 4 clamping and fixing. The bottom of the fixing slot 12 is an open design, which increases the heat dissipation effect of battery block 4 installed in battery compartment 1. The slide rail 3 is a self-locking slide rail.

[0028] Please see Figure 2 The battery compartment 1 has a side pressure plate 2 integrally formed on the side away from the slide rail 3, parallel to the slide rail 3. There are two side pressure plates 2, symmetrically distributed with the center of the battery compartment 1 as the origin. The corner of the side pressure plate 2 away from the slide rail 3 has a beveled cut 21. The end of the side pressure plate 2 away from the slide rail 3 has a first curved portion 22 and a second curved portion 23 integrally formed extending towards the other side pressure plate 2. Both the first curved portion 22 and the second curved portion 23 are perpendicular to the side pressure plate 2. There is a height difference gap between the first curved portion 22 and the second curved portion 23. The integrally formed side pressure plate 2 increases the height difference between the two sides. The overall strength and rigidity of the battery compartment 1 structure, along with the symmetrical distribution, ensures balanced force on both sides of the battery compartment 1. The design of the oblique cut 21 eliminates the sharp edges at the corners of the side pressure plate 2, preventing scratches to operators during the pulling and pulling of the battery compartment 1. At the same time, the opening of the oblique cut 21 can also guide the battery block 4 to be installed or separated from the battery compartment 1 more smoothly. The height difference gap between the first bending part 22 and the second bending part 23 provides a convenient and reliable insertion and fixing position for the protective cover 8, allowing the protective cover 8 to be initially positioned without additional fasteners.

[0029] Please see Figure 3 One end of the guide rod 5 is slidably connected to the inner side of the slide groove 11. The end of the guide rod 5 near the slide rail 3 has an integrally formed ball head 51, the distance between the ball heads 51 is greater than the width of the slide groove 11. The end of the guide rod 5 away from the slide rail 3 has an integrally formed cylindrical protrusion 52, the diameter of the protrusion 52 is greater than the diameter of the guide rod 5. The ball head 51 effectively prevents the guide rod 5 from accidentally falling out of the slide groove 11 during the sliding process, ensuring the stability of the guide rod 5 during sliding. The protrusion 52 provides an important support point for the return spring 7 and the sleeve 61, and is the structure for realizing the spring compression return and the sleeve 61 sliding guidance.

[0030] Please see Figure 4 The limiting component 6 includes: a sleeve 61, which is sleeved on the outside of the guide rod 5. One end of the sleeve 61, near the slide rail 3, is annularly wrapped around the outside of the guide rod 5 and slidably connected to the guide rod 5. The other end of the sleeve 61 is open and slidably connected to the outside of the protrusion 52; a pressure rod 62, which is integrally formed on the outside of the sleeve 61 at the end away from the slide rail 3. The pressure rods 62 are symmetrically distributed with the center of the sleeve 61 as the origin; and a rubber sleeve 63, which is fixedly connected to the outside of the pressure rod 62 and fits against the surface of the battery block 4. The arrangement of the sleeve 61 and one end annularly wrapped around the outside of the guide rod 5 provides a space for the return spring 7. The installation space allows the return spring 7 to be wrapped by the sleeve 61 for compression and reset, reducing the impact of external factors on the use of the return spring 7. The symmetrical distribution of the pressure rod 62 allows it to be perpendicular between the two side plates, applying clamping force to the battery block 4 and increasing the range of action of the pressure rod 62. The rubber sleeve 63 increases the friction with the surface of the battery block 4, preventing the pressure rod 62 from slipping off the outside of the battery block 4 and affecting the clamping effect. At the same time, the rubber sleeve 63 also provides elastic cushioning to avoid hard contact damage to the surface of the battery block 4, and can also adapt to the slight unevenness of the surface of the battery block 4 for a better fit, ensuring reliable and effective clamping.

[0031] Please see Figure 4The return spring 7 is inserted into the outside of the guide rod 5. One end of the return spring 7 is fixedly connected to the inner wall of the sleeve 61 near the slide rail 3, and the other end of the return spring 7 is fixedly connected to the protrusion 52 near the slide rail 3. The return spring 7 is inserted into the outside of the guide rod 5 and transmits the force axially to the sleeve 61 and the protrusion 52. When it is necessary to clamp the battery block 4, the sleeve 61 can be pulled to move away from the slide rail 3. During the movement, the sleeve 61 and the protrusion 52 move closer to each other and compress the return spring 7. The return spring 7 can generate a rebound force to act on the sleeve 61 and the protrusion 52, so that the pressure rod 62 and the rubber sleeve 63 press the battery block 4 to form a stable clamp. When the battery block 4 needs to be removed, the operator can continue to pull the sleeve 61 away from the slide rail 3 to create a gap between the pressure rod 62 and the battery block 4. Then the guide rod 5 is rotated along the slide groove 11 to both ends of the battery block 4 to cancel the clamping effect on the battery block 4 and facilitate the removal of the battery block 4.

[0032] Please see Figure 1 A protective cover 8 covering the oblique cut 21 is inserted into the outer side of the side pressure plate 2. The protective cover 8 has a right-angled triangular cross-section. One end of the protective cover 8 is inserted between the first curved part 22 and the second curved part 23, and the other end of the protective cover 8 extends to the outer side of the battery compartment 1. A through hole 81 is opened at the end of the protective cover 8 away from the first curved part 22. A limiter 9 is installed on the surface of the battery compartment 1. The limiter 9 passes through the through hole 81 and is fastened to the protective cover 8. The design of the through hole 81 provides a positioning and locking point for the limiter 9. The protective cover 8 is fixed by inserting with the first curved part 22 and the second curved part 23 through the height difference gap, and by fastening and locking with the limiter 9. It is easy to operate and not easy to loosen. At the same time, the protective cover 8 also effectively covers the oblique cut 21 of the side pressure plate 2, protecting the battery block 4.
