Abstract
Description
Technical Field
[0001] This utility model relates to the field of child safety seat technology, and more specifically, to a car-mounted pet safety seat. Background Technology
[0002] As people show more care for their pets and travel more frequently, car pet safety seats are gradually becoming essential equipment for pet owners. Their safety and suitability are directly related to the comfort and protection of pets during the journey. Currently, pet safety seats on the market face significant limitations, namely, the need to use different sized seats according to the different sizes of pets. However, pets' sizes change significantly during their growth and development, especially puppies and kittens, which may grow from small to medium or large sizes in a short period of time. This requires pet owners to frequently change safety seats to fit their current size, which not only increases the financial burden on pet owners but also wastes resources. At the same time, due to the high frequency of replacement, pets may need to repeatedly adapt to new seat environments, increasing the stress and discomfort of pets during travel.
[0003] Most existing pet car seats adopt an integrated fixed design, with the entire seat structure and size predetermined and non-adjustable. This means that pet owners need to equip each pet of different sizes with a dedicated car seat, or replace and reinstall the entire seat when different pets are traveling. This design not only increases the storage space occupied and the inconvenience of carrying the car, but also prolongs the preparation time for changing the seat and reduces travel efficiency. Especially in emergencies or when it is necessary to travel with different pets temporarily, the incompatibility of the seat may cause the pet to be unable to travel safely or be forced to travel in an unsafe manner, increasing the risk of injury to the pet in traffic accidents. This does not meet the comprehensive needs of modern pet owners for convenience, safety and economy. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, this utility model provides a car pet safety seat to solve the technical problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a vehicle-mounted pet safety seat, comprising a mounting base and a pet seat, wherein a quick-installation mechanism is provided between the mounting base and the pet seat, the quick-installation mechanism comprising a plug rod and a fixing plate, the plug rod being fixed to the top surface of the mounting base in multiple sets, the fixing plate being fixed to the bottom surface of the pet seat, a fixing sleeve being fixedly provided on the fixing plate, a retaining ring being fixedly provided inside the fixing sleeve, a movable groove being provided on the outer wall of the plug rod, the movable groove being provided in multiple sets and each having a slidable locking block inside, a push spring being connected between each set of locking blocks and the inner wall of the movable groove, the push spring being provided in multiple sets, a sliding groove being provided on the outer wall of the fixing sleeve, the sliding groove being provided in multiple sets and a sliding sleeve being slidably provided inside, an unlocking sleeve being fixedly provided on the inner wall of the sliding sleeve.
[0008] The present invention is further configured such that the fixing plate is provided with insertion holes, and the insertion holes are provided in multiple sets, and the outer walls of each set are provided with rounded corners. This design provides an optimized insertion guide structure. The rounded outer walls allow the insertion rod to smoothly guide the retraction of the locking block during insertion, reducing insertion friction and resistance, reducing the force required during installation, and avoiding wear and shortened service life of the locking block caused by hard edges, thereby improving the smoothness of the entire quick installation process and the user experience.
[0009] This utility model is further configured such that the outer wall of the fixed sleeve is provided with a limiting mechanism, the limiting mechanism including a limiting sleeve and a rotating sleeve. The limiting sleeve is fixed to the bottom surface of the sliding sleeve, the rotating sleeve rotates on the outer wall of the fixed sleeve and a sliding rod is fixedly provided on its top surface. Multiple sets of sliding rods are provided, and each has a limiting block fixed at its top. A limiting hole is opened inside the limiting sleeve, and multiple sets of limiting holes are provided, each with an unlocking hole at one end. This mechanism forms a safe and reliable locking system. By rotating the rotating sleeve, the position of the sliding rod and the limiting block is controlled, thereby locking and unlocking the limiting sleeve. This prevents the unlocking sleeve from accidentally sliding due to vibration during vehicle operation, ensuring that the pet seat is firmly fixed. At the same time, it provides a simple and intuitive operation method, allowing users to complete the disassembly and assembly without professional tools.
[0010] The present invention is further configured such that the inner wall of the retaining ring and the top of the multiple sets of retaining blocks are provided with inclined surfaces. This inclined surface design realizes a self-guiding locking function. When the insert rod is inserted into the fixed sleeve, the inclined surface at the top of the retaining block and the inclined surface of the inner wall of the retaining ring form a complementary guiding surface, so that the retaining block can smoothly retract into the movable groove, and form a reliable locking contact when it pops out, which enhances the stability and safety of the connection, while reducing the impact wear between the retaining block and the retaining ring, and extending the service life of the component.
[0011] The present invention is further configured such that a tension spring is connected to the bottom surface of the limiting sleeve. This tension spring design provides an automatic driving force system. When the limiting mechanism is unlocked, the tension spring releases the stored elastic potential energy, automatically pulling the limiting sleeve and the sliding sleeve downward, driving the unlocking sleeve to push the locking block. This eliminates the need for the user to continuously apply external force, simplifies the operation steps in the disassembly process, and improves the disassembly efficiency. It is especially suitable for use in emergency situations or when a pet seat needs to be quickly replaced.
[0012] The present invention is further configured such that a thrust bearing is connected between the bottom end of the tension spring and the rotating sleeve. This structure creates a decoupling system between rotation and tension. The thrust bearing allows the rotating sleeve to rotate freely without affecting the transmission of tension from the tension spring, reducing frictional resistance during rotation, improving the smoothness and accuracy of rotation, and preventing the tension spring from twisting and deforming during rotation, thus extending the service life of the tension spring and ensuring its reliability for long-term use.
[0013] The present invention is further configured such that the diameter of the multiple sets of unlocking holes is greater than that of the limiting block. This dimensional relationship design ensures the smoothness of the disassembly process. When the limiting block enters the unlocking hole with a larger diameter, a sufficient gap is formed between the limiting block and the unlocking hole, allowing the limiting sleeve to slide smoothly under the action of the tension spring without being obstructed by the limiting block. At the same time, it prevents the limiting block from interfering with and rubbing against the edge of the unlocking hole in the unlocked state, thereby improving the smoothness of operation and the durability of the components.
[0014] The present invention is further configured such that an ISOFIX assembly is fixedly provided on the outer wall of the mounting base. This standardized connection system enables safe and reliable fixation to the vehicle seat. The ISOFIX assembly complies with international automotive safety standards and provides rigid connection points to ensure that the mounting base will not loosen or shift in the event of emergency braking or collision. This significantly improves the safety performance of the entire pet safety seat and simplifies the installation process, allowing users to quickly and accurately fix the seat in the vehicle. It is suitable for various vehicle models equipped with ISOFIX interfaces.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a car pet safety seat with the following features:
[0017] Beneficial effects:
[0018] 1. This quick-installation mechanism consists of a plug rod and a fixing plate. Together with the locking block and push-spring system within the movable slot, it enables a rapid connection between the pet seat and the mounting base. In use, simply insert the plug rod into the hole on the fixing plate; the locking block will automatically pop out under the action of the push-spring and engage with the retaining ring to lock it in place. This modular design allows pet owners to quickly change to a suitable pet seat according to the different size requirements of their pets. The mounting base is securely fixed to the car seat via the ISOFIX assembly, remaining unchanged. This not only significantly reduces the economic cost of replacing seats but also reduces resource waste, while improving the convenience and flexibility of travel and meeting the needs of pets at different growth stages.
[0019] 2. Through the coordinated operation of the rotating sleeve and the limiting sleeve, the pet seat can be disassembled with one click. When the pet seat needs to be replaced, simply rotate the rotating sleeve counterclockwise to move the sliding rod and the limiting block to the unlocking hole, releasing the restriction on the limiting sleeve. Under the action of the tension spring, the limiting sleeve drives the unlocking sleeve to slide, pushing the locking block back into the movable groove, thereby unlocking the lock. The entire disassembly process is simple and intuitive, requiring no tools, greatly reducing the difficulty of operation and time cost. At the same time, the rounded corner design of the outer wall of the socket provides a good guiding effect, ensuring that the plug can be inserted smoothly, further improving the convenience of installation. This user-friendly design is particularly suitable for use in emergency situations or when it is necessary to temporarily change different pets, improving travel efficiency and enhancing the user experience.
[0020] 3. The beveled design of the inner wall of the retaining ring and the top of the retaining block provides a self-guiding function, allowing the retaining block to slide in and lock smoothly. The limiting hole and unlocking hole in the limiting mechanism are ingeniously designed to ensure that the rotating sleeve will not rotate accidentally under normal use, preventing the pet seat from loosening during travel. At the same time, the application of the thrust bearing allows the rotating sleeve to rotate smoothly without affecting the tension transmission of the tension spring, improving the comfort of operation. The overall structure is compact and robust. The ISOFIX assembly provides a standardized connection with the vehicle seat, meets automotive safety standards, ensures the stability of the pet seat in the event of emergency braking or collision, comprehensively protects the safety of pets during travel, and meets the comprehensive needs of modern pet owners for safety, convenience, and economy.

[0028] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0030] Please see Figures 1-5 A car-mounted pet safety seat includes a mounting base 1 and a pet seat 2. A quick-release mechanism is provided between the mounting base 1 and the pet seat 2. The quick-release mechanism includes a plug rod 3 and a fixing plate 4. The plug rod 3 is fixed to the top surface of the mounting base 1 in multiple sets. The fixing plate 4 is fixed to the bottom surface of the pet seat 2. A fixing sleeve 5 is fixed on the fixing plate 4. A retaining ring 6 is fixed inside the fixing sleeve 5. The outer wall of the plug rod 3 has a movable groove 7. The movable groove 7 has multiple sets, and each of the movable grooves 7 has a sliding block 8. Each of the multiple sets of retaining blocks 8 is connected to the inner wall of the movable groove 7 with a push spring 9. Each of the push springs 9 has multiple sets. The outer wall of the fixing sleeve 5 has a sliding groove 10. The sliding groove 10 has multiple sets, and a sliding sleeve 11 is slidably provided inside. An unlocking sleeve 12 is fixed to the inner wall of the sliding sleeve 11.
[0031] The fixing plate 4 has multiple sets of insertion holes 13, and the outer walls of each hole are rounded. This design is based on the guiding principle. The rounded corner structure forms a progressive guiding surface. When the insertion rod 3 is inserted into the insertion hole 13, the rounded corner surface guide block 8 is smoothly compressed into the movable groove 7, which reduces the resistance and impact during the insertion process and prevents wear caused by hard contact between the block 8 and the edge of the insertion hole 13. At the same time, the rounded corner shape increases the guiding area of the initial contact, reduces the positional accuracy requirements of the insertion, and makes the installation operation more convenient.
[0032] The outer wall of the fixed sleeve 5 is provided with a limiting mechanism, which includes a limiting sleeve 14 and a rotating sleeve 15. The limiting sleeve 14 is fixed to the bottom surface of the sliding sleeve 11. The rotating sleeve 15 rotates on the outer wall of the fixed sleeve 5 and has a sliding rod 16 fixed on its top surface. Multiple sets of sliding rods 16 are provided, and each has a limiting block 17 fixed at its top. A limiting hole 18 is provided inside the limiting sleeve 14. Multiple sets of limiting holes 18 are provided, and each has an unlocking hole 19 at one end. This mechanism adopts the principle of rotation control. The rotational movement of the rotating sleeve 15 is converted into the circumferential displacement of the limiting block 17. When the limiting block 17 is located in the limiting hole 18, the limiting sleeve 14 is restricted to a fixed position. When the rotating sleeve 15 rotates and moves the limiting block 17 to the unlocking hole 19, the limiting sleeve 14 gains axial movement freedom. This conversion mechanism transforms a simple rotational operation into a complex locking and unlocking function, providing an intuitive user interface and reliable safety assurance.
[0033] The inner wall of the retaining ring 6 and the top of the multiple sets of retaining blocks 8 are all provided with inclined surfaces. This structure is based on the wedge guide principle. When the insert rod 3 is inserted into the fixed sleeve 5, the inclined surface at the top of the retaining block 8 contacts the inclined surface of the inner wall of the retaining ring 6, generating a radial component force that causes the retaining block 8 to overcome the elastic force of the push spring 9 and retract into the movable groove 7. When the retaining block 8 has completely passed through the retaining ring 6, the push spring 9 releases energy to push the retaining block 8 out. The bottom surface of the retaining block 8 and the upper surface of the retaining ring 6 form an axial limit. This automatic locking mechanism can complete a firm connection without additional operation.
[0034] A tension spring 20 is connected to the bottom surface of the limiting sleeve 14. This design utilizes the principle of elastic potential energy storage. The tension spring 20 is in a stretched state when assembled and stores elastic potential energy. When the limiting block 17 enters the unlocking hole 19 and releases the restriction on the limiting sleeve 14, the tension spring 20 releases potential energy to generate tension, which automatically drives the limiting sleeve 14 and the connected sliding sleeve 11 to move downward, thereby driving the unlocking sleeve 12 to push the locking block 8 to retract. This energy pre-storage mechanism allows the automatic unlocking system to be activated by a simple rotation operation during the disassembly process.
[0035] A thrust bearing 21 is provided between the bottom end of the tension spring 20 and the rotating sleeve 15. This mechanism is based on the principle of force transmission decoupling. The thrust bearing 21 allows the tension spring 20 and the rotating sleeve 15 to rotate relative to each other while maintaining axial connection. When the user rotates the rotating sleeve 15, the rolling elements of the thrust bearing 21 reduce rotational friction, making operation easier. At the same time, it ensures that the tension spring 20 will not be torsional deformed due to rotation, thus ensuring stable transmission of tension and service life of the tension spring 20.
[0036] The diameter of the multiple unlocking holes 19 is greater than that of the limiting block 17. This design applies the principle of clearance fit. The larger diameter of the unlocking holes 19 ensures that the limiting block 17 will not interfere with the axial movement of the limiting sleeve 14 after it enters. When the limiting block 17 is inside the unlocking hole 19, the limiting sleeve 14 can slide smoothly downward under the action of the tension spring 20. At the same time, the larger clearance reduces friction and collision between components, improving the operational reliability and service life of the mechanism.
[0037] An ISOFIX assembly 22 is fixedly installed on the outer wall of the mounting base 1. This structure adopts the internationally standardized connection principle. The ISOFIX assembly 22 provides a rigid connection point with the ISOFIX interface of the car seat. Through a standardized locking mechanism and support structure, a high-strength fixed connection is formed to ensure the stability of the mounting base 1 during vehicle operation, especially in the case of emergency braking or collision. This connection method avoids the loosening problem of traditional seat belt fixing and provides a higher level of safety protection.
[0038] In this embodiment, during use, the mounting base 1 is installed on the car seat via the ISOFIX assembly 22. When the multiple sets of insert rods 3 are inserted into the sockets 13, the multiple sets of locking blocks 8 are pushed into the movable slots 7 by the rounded corners on the outer walls of the multiple sets of sockets 13. After the insert rods 3 are inserted into the sockets 13, they are inserted into the fixing sleeves 5. After the multiple sets of locking blocks 8 are fully inserted into the fixing sleeves 5, the multiple sets of push springs 9 reset and push the locking blocks 8 out of the movable slots 7, and the locking rings 6 abut against the bottom surfaces of the multiple sets of locking blocks 8, thus completing the quick installation of the pet seat 2.
[0039] More specifically, when the pet seat 2 needs to be disassembled, the counterclockwise rotation of the rotating sleeve 15 drives the multiple sets of sliding rods 16 to rotate, causing the multiple sets of limiting blocks 17 to move to the unlocking hole 19 and release the contact between the limiting blocks 17 and the limiting sleeve 14. The tension spring 20 pulls the limiting sleeve 14 and the sliding sleeve 11, causing the unlocking sleeve 12 to slide along the sliding groove 10. The unlocking sleeve 12 pushes the multiple sets of locking blocks 8 to slide into the movable groove 7 to release the contact with the locking ring 6, and at the same time squeezes the multiple sets of push springs 9. After the multiple sets of limiting blocks 17 slide out of the unlocking hole 19, the clockwise rotation causes the multiple sets of sliding rods 16 to slide into the limiting hole 18, causing the multiple sets of limiting blocks 17 to abut against the outer wall of the limiting sleeve 14, limiting the unlocking sleeve 12 and keeping it in a continuously unlocked state. Then the pet seat 2 can be disassembled.
[0040] In summary, when using or operating the entire device: During use, the mounting base 1 is installed on the car seat via the ISOFIX assembly 22. When the multiple sets of insert rods 3 are inserted into the sockets 13, the rounded corners on the outer walls of the multiple sets of sockets 13 push the multiple sets of locking blocks 8 into the movable slots 7. After the insert rods 3 are inserted into the sockets 13, they are inserted into the fixing sleeves 5. After the multiple sets of locking blocks 8 are fully inserted into the fixing sleeves 5, the multiple sets of push springs 9 reset and push the locking blocks 8 out of the movable slots 7, and the retaining rings 6 abut against the bottom surfaces of the multiple sets of locking blocks 8, thus completing the quick installation of the pet seat 2.
[0041] When the pet seat 2 needs to be disassembled, the counterclockwise rotation of the rotating sleeve 15 drives the multiple sets of sliding rods 16 to rotate, causing the multiple sets of limiting blocks 17 to move to the unlocking hole 19 and release the contact between the limiting blocks 17 and the limiting sleeve 14. The tension spring 20 pulls the limiting sleeve 14 and the sliding sleeve 11, causing the unlocking sleeve 12 to slide along the sliding groove 10. The unlocking sleeve 12 pushes the multiple sets of locking blocks 8 to slide into the movable groove 7 to release the contact with the locking ring 6, and at the same time squeezes the multiple sets of push springs 9. After the multiple sets of limiting blocks 17 slide out of the unlocking hole 19, the clockwise rotation causes the multiple sets of sliding rods 16 to slide into the limiting hole 18, so that the multiple sets of limiting blocks 17 abut against the outer wall of the limiting sleeve 14, limiting the unlocking sleeve 12 and keeping it in a continuously unlocked state. Then the pet seat 2 can be disassembled.

They will not be elaborated here. For all the fixed connections mentioned above, welding is the preferred option.
