Description

Technical Field

[0001] This utility model relates to the field of battery fixing technology, specifically to a quick-release battery fixing structure and an electric luggage case. Background Technology

[0002] With the rapid development of electrification technology, various mobile devices (such as electric suitcases and portable devices) are increasingly reliant on batteries. The installation stability, ease of disassembly, and maintenance efficiency of batteries have become key factors affecting product experience. However, existing battery mounting structures generally suffer from numerous technical shortcomings, making it difficult to meet users' needs for efficient, safe, and convenient use.

[0003] Currently, the mainstream battery fixing methods on the market mostly adopt threaded connections, snap-locking, or sliding rail structures. While threaded connections provide strong fixing force, they require tools such as screwdrivers for installation and removal, making the process cumbersome and time-consuming, especially in inconvenient outdoor scenarios where tools are unavailable. Snap-locking structures, while tool-free, are prone to loosening or failure due to vibration and impact, causing battery displacement or even detachment, posing a safety hazard. Sliding rail structures simplify the installation and removal process, but have many parts, complex assembly, and the clearance between the rail and the battery tends to increase over long-term use, causing battery wobbling and affecting device stability.

[0004] Meanwhile, stability under complex operating conditions is also a problem that urgently needs to be solved. Mobile equipment often faces multi-dimensional external forces such as vibration and impact during transportation and use. Traditional fixed structures cannot ensure that the battery always maintains a stable fit, which may cause problems such as poor electrode contact and circuit failure, affecting the normal operation of the equipment.

[0005] Therefore, the market urgently needs a quick-release battery fixing structure that can be quickly installed and removed without tools, has excellent vibration resistance, a simple structure, and low cost, in order to meet the usage requirements under complex working conditions, improve user experience, and promote the technological upgrading of related equipment.

The bottom surface of the limiting block is in contact with the top surface of the battery.

[0009] In the above technical solution, the receiving slot can provide a space for the battery, and the casing can protect the battery. When the battery is in the receiving slot, the first spring is in a relaxed state, and the bottom end of the limiting block is in contact with the battery, thereby limiting the battery by the limiting block. When it is necessary to remove the battery, the limiting block is pushed towards the side of the first spring, so that the limiting block no longer obstructs the battery, making it convenient for the user to remove the battery from the receiving slot.

[0010] The combination of the first spring and the limiting block allows the limiting block to fit tightly against the battery, maintaining battery stability even under vibration or impact conditions. This design not only improves the battery's secure mounting reliability but also simplifies the installation and removal process, eliminating the need for tools and significantly enhancing the user experience.

[0011] Preferably, the limiting mechanism further includes a first mounting base and a first guide rod. The first mounting base is fixedly mounted on the housing.

[0015] Preferably, the lifting mechanism further includes a second mounting base, which is mounted on the electrical equipment. The two ends of the second spring abut against the second mounting base and the protrusion, respectively. The second mounting base has a second guide hole for the second guide rod to slide.

[0016] Preferably, a mating block is provided on the outer periphery of one end of the sliding rod located inside the housing, and the mating block abuts against the bottom end of the battery.

[0017] Preferably, the lifting mechanism consists of several third springs vertically arranged at the bottom of the housing, and the third springs abut against the bottom of the battery.

[0018] Preferably, the receiving groove is narrow at the bottom and wide at the top, and the inner sidewall of the bottom end of the receiving groove is in contact with the outer periphery of the bottom of the battery.

[0019] This utility model also provides an electric luggage case, including a quick-release battery fixing structure as described in any of the above solutions, wherein the quick-release battery fixing structure is installed on the electric luggage case.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This quick-release battery fixing structure, through the combination of a first spring and a limiting block, ensures that the limiting block fits tightly against the battery, maintaining battery stability even under vibration or impact conditions. This design not only improves the reliability of battery fixing but also simplifies the installation and removal process, eliminating the need for tools and greatly enhancing the user experience.

[0022] 2. In this quick-release battery fixing structure, the first guide rod effectively prevents the limiting block from causing the spring to shift upwards under the pressure of the battery, thus ensuring that the spring is always in the correct direction of force and working state. This design not only improves the stability and reliability of the limiting mechanism and extends its service life, but also further enhances the overall performance of the quick-release battery fixing structure, enabling the battery to maintain a stable and reliable fixed state during installation and use.

[0023] 3. In this quick-release battery fixing structure, the second guide rod can guide the second spring by sliding in the through hole, so as to prevent the second spring from shifting when the battery is pressed down.

[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Please refer to Figures 1 to 6 The quick-release battery fixing structure in this solution includes a housing 1, a battery 2, and a limiting mechanism 3.

[0034] The housing 1 has a receiving groove for installing the battery 2. The battery 2 is installed in the receiving groove. The limiting mechanism 3 is installed above the receiving groove. The limiting mechanism 3 includes a first spring 31 and a limiting block 32. One end of the first spring 31 is installed in the housing 1, and the other end of the first spring 31 is connected to the limiting block 32. The bottom surface of the limiting block 32 is in contact with the top surface of the battery 2.

[0035] In the above technical solution, the receiving slot can provide a receiving space for the battery 2, and the housing 1 can protect the battery 2. When the battery 2 is located in the receiving slot, the first spring 31 is in a relaxed state, and the bottom end of the limiting block 32 is in contact with the battery 2, thereby limiting the battery 2 by the limiting block 32. When it is necessary to remove the battery 2, the limiting block 32 is pushed towards the side of the first spring 31, so that the limiting block 32 no longer blocks the battery 2, making it convenient for the user to remove the battery 2 from the receiving slot.

[0036] The combination of the first spring 31 and the limiting block 32 allows the limiting block 32 to fit tightly against the battery 2, maintaining the stability of the battery 2 even under vibration or impact conditions. This design not only improves the reliability of the battery 2's fixation but also simplifies the installation and disassembly process, eliminating the need for tools and greatly enhancing the user experience.

[0037] Please refer to Figures 1 to 3 Preferably, the limiting mechanism 3 further includes a first mounting base 33 and a first guide rod 34. The first mounting base 33 is fixedly mounted on the housing 1. A first guide hole is provided on the first mounting base 33. One end of the first guide rod 34 slides in the first guide hole of the first mounting base 33. The other end of the first guide rod 34 is connected to the limiting block 32. A first spring 31 is sleeved on the outer periphery of the first guide rod 34.

[0038] In the above technical solution, the first guide rod 34 can effectively prevent the limiting block 32 from causing the spring to shift upward under the pressure of the battery 2, thereby ensuring that the spring is always in the correct direction of force and working state. This design not only improves the stability and reliability of the limiting mechanism 3 and extends its service life, but also further enhances the overall performance of the quick-release battery fixing structure, enabling the battery 2 to maintain a stable and reliable fixed state during installation and use.

[0039] Preferably, the limiting block 32 has a guide slope that facilitates the sliding of the battery 2 into the housing 1.

[0040] In the above technical solution, the inclined surface can be either a plane or a curved surface. The inclined surface design allows the user to install the battery 2 without manually pushing the limiting block 32 away. The user simply presses the battery 2 down, and the weight and shape of the battery 2 will automatically move the limiting block 32 towards the side closer to the first spring 31, thus allowing the battery 2 to enter the receiving slot. This design reduces the complexity of manual operation, eliminating the need for manual pushing of the limiting block 32 and further improving the user experience.

[0041] Please refer to Figures 4 to 6 Preferably, it also includes a lifting mechanism 4 installed at the bottom of the housing 1. The lifting mechanism 4 is used to lift the battery 2 upward, and the top of the battery 2 abuts against the bottom of the limiting block 32.

[0042] In the above technical solution, the lifting mechanism 4 is used to lift the battery 2 upward, so that after the user pushes the limiting block 32 to one side of the first spring 31, the limiting block 32 no longer limits the battery 2, and the battery 2 can be automatically lifted under the action of the lifting mechanism 4, making it convenient for the user to hold the top of the battery 2 and take it out.

[0043] In some embodiments, the bottom of the housing 1 is provided with a plurality of through holes, and the lifting mechanism 4 includes a second spring 41 and a second guide rod 42. The second guide rod 42 includes a sliding rod 421 slidably connected in the through holes and a protrusion 422 disposed on the outer periphery of the sliding rod 421. The protrusion 422 is located outside the housing 1, and the second spring 41 is sleeved on the outer periphery of the sliding rod 421 with its two ends abutting against the electrical equipment and the protrusion 422 respectively.

[0044] In the above technical solution, the second guide rod 42 can guide the second spring 41 by sliding in the through hole, so as to prevent the second spring 41 from deviating when the battery 2 is pressed down. When the second guide rod 42 moves downward, the protrusion 422 can drive the second spring 41 to compress. After the limiting block 32 stops limiting the battery 2, the second spring 41 can use its own restoring force to lift the battery 2. The electrical device can be an electric suitcase, a drone or other electrical device.

[0045] Preferably, the lifting mechanism 4 further includes a second mounting base 43, which is mounted on the electrical equipment. The two ends of the second spring 41 abut against the second mounting base 43 and the protrusion 422 respectively. The second mounting base 43 is provided with a second guide hole for the second guide rod 42 to slide.

[0046] In the above technical solution, the second guide hole on the second mounting base 43 can further guide the second guide rod 42 and at the same time avoid the second guide rod 42. The setting of the second mounting base 43 can facilitate the installation of the second spring 41 and the second guide rod 42 on the electrical equipment.

[0047] Please refer to Figure 5 and Figure 6 Preferably, a mating block 44 is provided on the outer periphery of one end of the sliding rod 421 located inside the housing 1, and the mating block 44 abuts against the bottom end of the battery 2.

[0048] In the above technical solution, the shape of the mating block 44 depends on the shape of the part that abuts against the battery 2. The setting of the mating block 44 can increase the contact area between the second guide rod 42 and the battery 2, thereby providing stable support for the battery 2 by the second guide rod 42.

[0049] In some embodiments, the lifting mechanism 4 consists of several third springs vertically arranged at the bottom of the housing 1, with the third springs abutting against the bottom of the battery 2.

[0050] In the above technical solution, the third spring (not shown in the figure) abuts against the bottom of the battery 2, providing a stable elastic force to the battery 2. This ensures that after the limiting block 32 no longer limits the battery 2, the battery 2 can be lifted upwards under the restoring force of the third spring. This design simplifies the structure of the lifting mechanism 4 while still meeting the lifting requirements of the battery 2.

[0051] Preferably, the receiving groove is narrow at the bottom and wide at the top, and the inner sidewall of the bottom end of the receiving groove is in contact with the outer periphery of the bottom of the battery 2.

[0052] In the above technical solution, since the upper part of the receiving groove is wider, the battery 2 can be placed into the receiving groove more easily when it is placed in. The lower part of the receiving groove is narrower, and the inner wall of the receiving groove is in contact with the outer periphery of the bottom of the battery 2. The groove wall can be used to limit the battery 2 and prevent the battery 2 from moving horizontally under the action of external force.

[0053] Please refer to Figure 1 and Figure 2 Preferably, the top of the battery 2 is provided with a carrying hole 5.

[0054] In the above technical solution, compared to the user directly holding the top of the battery 2 to remove it, the handle hole makes it easier for the user to carry the battery 2. This design not only improves the user experience of the quick-release battery fixing structure, but also makes the transport of the battery 2 more convenient and faster, further enhancing the overall convenience of the quick-release battery fixing structure.

[0055] This utility model also provides an electric luggage case, including a quick-release battery fixing structure of any of the above solutions, wherein the quick-release battery fixing structure is installed on the electric luggage case.

[0056] In the above solution, the battery 2 can be stably installed on the suitcase by the action of the limiting mechanism 3 and the lifting mechanism 4, which prevents the battery 2 from moving or shaking under the action of external force. At the same time, the lifting mechanism 4 can make it convenient for the user to push out the battery 2 when needed.

[0057] Work style:

[0058] When the user needs to install battery 2, first open the trunk lid and place battery 2 from top to bottom towards the receiving slot. The slot wall is designed with a certain draft angle, and the entrance opening is slightly larger, allowing for quick positioning even in poor visibility or when wearing gloves. The bottom surface of battery 2 first contacts the inclined surface of the limiting block 32. The weight of battery 2 itself pushes the limiting block 32 towards the inside of the housing 1, compressing the first spring 31 and causing the limiting block 32 to automatically retract. Battery 2 continues to move downwards until it is fully inside the receiving slot. At this point, the first spring 31 is released, and the limiting block 32 instantly resets, its right-angled bottom edge firmly abutting the top surface of battery 2, completing the tool-free automatic locking. Throughout the process, the first guide rod 34 slides within the guide hole of the first mounting base 33, ensuring that the limiting block 32 always moves horizontally and will not deviate due to lateral torque. During vehicle operation, the multidimensional impacts on battery 2 are transmitted to the first spring 31 through the limiting block 32. Under the constraint of the first guide rod 34, the first spring 31 only undergoes slight axial deformation, avoiding permanent fatigue and maintaining a long-lasting clamping force. When battery 2 needs to be removed, the user holds the top of battery 2 with one hand and uses their thumb to laterally push the exposed limiting block 32, causing it to compress the first spring 31 again and disengage from the top surface of battery 2, instantly releasing the lock. At the same time, the pre-compressed second spring 41 at the bottom of housing 1 loses the downward pressure constraint of battery 2, releasing its stored elastic potential energy and pushing the second guide rod 42 vertically upward along the through hole. The cooperating block 44 then makes large-area contact with the bottom surface of battery 2, smoothly lifting battery 2 upward, and the lifting hole 5 on the top of battery 2 is exposed at the edge of the housing. The user can easily lift battery 2 without any tools, completing the entire disassembly process.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
