Description

Technical Field

[0001] This utility model relates to the technical field of car child seat accessories, and in particular to an angle adjustment motor for car child seats. Background Technology

[0002] With the development of the automotive industry and the increasing awareness of children's safety, car child seats, as key equipment to ensure children's safety while riding in a car, are receiving more and more attention for their functional design. Among them, the seat angle adjustment function can be flexibly adjusted according to the child's sitting posture, age and usage scenario, which is an important part of improving riding comfort and safety.

[0003] To meet the demands for convenience and precision in angle adjustment, electric angle adjustment devices are gradually replacing traditional manual adjustment mechanisms and becoming the mainstream technology. Electric angle adjustment devices typically rely on an angle adjustment motor for power, and the rotational motion of the motor is converted into seat angle adjustment through a transmission component, achieving automated adjustment, reducing manual operation errors, and improving ease of use. Among them, Chinese patent with publication number CN222591303U discloses an automatic angle adjustment device for child safety seats based on touch screen control. It achieves angle adjustment through the threaded engagement of the angle adjustment motor output shaft and the adjustment plate, significantly improving the angle adjustment accuracy and ease of operation, representing the development trend of electric angle adjustment technology.

[0004] However, when the angle adjustment motor malfunctions due to long-term use and needs repair or replacement, existing technologies (including the structure disclosed in CN222591303U) often use multiple bolts or other fasteners to achieve a rigid connection between the angle adjustment motor and the mounting bracket. Repair personnel need to use tools to disassemble these fasteners one by one in order to remove the angle adjustment motor. However, the interior of child seats often has grooves, arc-shaped angle adjustment plates, and other structures to accommodate angle adjustment-related components, resulting in a relatively narrow operating space around the angle adjustment motor. Disassembling multiple fasteners in a narrow space is not only cumbersome, but also prone to prolonging repair time due to limited tool access. It may even lead to accidental contact with other components inside the seat during disassembly, affecting the overall performance of the angle adjustment device. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an angle adjustment motor for car child seats, solving the problems of inconvenient disassembly, cumbersome disassembly and assembly procedures, and the potential for extended maintenance time due to limited tool access.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An angle adjustment motor for a car child seat includes an angle adjustment motor and a fixing plate for fixing the car child seat. The fixing plate is provided with a locking member for quickly clamping and fixing the angle adjustment motor to the fixing plate. The angle adjustment motor can be quickly assembled or disassembled with the fixing plate through the locking member. The locking member forms a position constraint on the angle adjustment motor through mechanical pressing.

[0007] Preferably, the angle-adjusting motor includes a drive device, a reduction gearbox, a drive screw, and a mounting plate. The reduction gearbox is formed by connecting a housing and a cover plate. The drive screw is rotatably mounted on the housing via bearings. The output shaft of the drive device passes through the housing and is provided with a transmission assembly. The output shaft of the drive device and the drive screw are connected by the transmission assembly. When in use, the transmission assembly is a gear set composed of multiple gears, which can transmit power. When in use, the drive device can be a motor. When the output shaft of the motor rotates, it drives the drive screw to rotate synchronously through the transmission assembly.

[0008] Preferably, the housing is provided with a mounting plate that mates with the locking element, and the mounting plate provides a flat and stable mating base for the locking element.

[0009] Preferably, the fixed frame plate is provided with a positioning rod, and the mounting plate of the angle adjustment motor is provided with a positioning hole that matches the positioning rod. The cooperation between the positioning rod and the positioning hole can realize the quick pre-positioning of the angle adjustment motor, eliminating the need for repeated alignment during installation. Especially in the narrow space inside the child seat, this can greatly simplify the installation operation and improve installation efficiency.

[0010] Preferably, the fixed frame plate is further provided with connecting holes, moving holes, and through holes. The through holes are used to avoid the drive device and drive screw of the angle adjustment motor. The moving holes provide precise guidance for the sliding of the locking plate, ensuring that the locking plate moves only in a preset direction, avoiding deviation or jamming during the locking process, and ensuring the stability and consistency of the locking action. The through holes can provide clearance space for the drive device and drive screw. The connecting holes provide a stable foundation for the installation of the locking component, ensuring the connection strength between the locking component and the fixed frame plate, and preventing the locking component from loosening itself when locking.

[0011] Preferably, the locking component includes a rotating plate, a bolt, a locking plate, and a limiting slider. The bolt passes through the rotating plate and is threadedly engaged with the connecting hole on the fixed frame plate. The limiting slider is fixed to the bottom of the locking plate and is movably embedded in the moving hole on the fixed frame plate. The engagement between the limiting slider and the moving hole can strictly constrain the movement trajectory of the locking plate, so that the locking plate only makes linear movements when locking or unlocking, avoiding poor positioning surface fit due to offset and improving the reliability of locking.

[0012] Preferably, the bolt and the rotating plate are eccentrically connected. The eccentric connection allows the rotating plate to generate a large thrust through the change of eccentricity when it rotates under the action of the bolt. The locking plate can be pushed to complete the locking action with a small bolt rotation angle, realizing "small operation amount for large locking force" and improving locking efficiency.

[0013] Preferably, two sets of locking members are symmetrically arranged on the fixed frame plate. The two locking members are respectively symmetrically positioned on both sides of the angle-adjusting motor to clamp and fix it. The symmetrically arranged locking members apply locking force synchronously from both sides of the angle-adjusting motor, so that the motor is subjected to balanced force and avoids motor tilting caused by force on one side. This ensures the verticality and stability of the motor after installation. Moreover, the clamping method on both sides can form a more comprehensive position constraint. Whether the vehicle is accelerating, braking or turning, the motor is not easy to shake or shift, which enhances the vibration resistance of the overall structure.

[0014] Preferably, the mounting plate has symmetrically inclined positioning surfaces one, and the locking plate has an inclined positioning surface two that cooperates with the positioning surface one. When the inclined surfaces cooperate, they can convert the horizontal thrust of the locking plate into a vertical pressing force on the mounting plate, thereby increasing the effective locking force and improving the locking firmness. Even under long-term vibration, it is not easy to loosen.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention enables quick assembly and disassembly of the angle-adjusting motor through locking components, eliminating the need for repeated disassembly of multiple fasteners and greatly simplifying maintenance operations. It is especially suitable for use in the narrow spaces of child seats. The positioning rod and positioning hole work together to achieve precise pre-positioning, avoiding component interference caused by installation deviations. The symmetrically arranged locking components push the locking plate through an eccentric structure, and with the fit of the inclined positioning surface, the horizontal thrust is converted into vertical clamping force, forming a balanced and stable clamping constraint, effectively resisting vehicle vibration and impact, and ensuring stable motor operation.

Example

[0023] Please see Figure 1-7An angle adjustment motor for a car child seat includes an angle adjustment motor 1 and a fixing plate 2 for fixing the car child seat. The fixing plate 2 is provided with a locking member 3 for quickly clamping and fixing the angle adjustment motor 1 to the fixing plate 2. The angle adjustment motor 1 can be quickly assembled or disassembled with the fixing plate 2 through the locking member 3. The locking member 3 forms a position constraint on the angle adjustment motor 1 through mechanical pressing.

[0024] The angle-adjusting motor 1 includes a drive device 11, a gearbox, a drive screw 14, and a mounting plate 15. The gearbox is formed by connecting a housing 12 and a cover plate 13. The drive screw 14 is rotatably mounted on the housing 12 via bearings. The output shaft of the drive device 11 passes through the housing 12 and is provided with a transmission assembly 18. The output shaft of the drive device 11 and the drive screw 14 are connected by the transmission assembly 18. When in use, the transmission assembly 18 is a gear set composed of multiple gears, which can transmit power. When in use, the drive device 11 can be a motor. When the output shaft of the motor rotates, it drives the drive screw 14 to rotate synchronously through the transmission assembly 18.

[0025] The housing 12 is provided with a mounting plate 15 that cooperates with the locking component 3. The mounting plate 15 provides a flat and stable base for the locking component 3.

[0026] The fixed frame plate 2 is provided with a positioning rod 24, and the mounting plate 15 of the angle adjustment motor 1 is provided with a positioning hole 17 that is compatible with the positioning rod 24. The cooperation between the positioning rod 24 and the positioning hole 17 can realize the quick pre-positioning of the angle adjustment motor 1. There is no need to repeatedly align during installation. Especially in the narrow space inside the child seat, it can greatly simplify the installation operation and improve the installation efficiency.

[0027] The fixed frame plate 2 is also provided with a connecting hole 23, a moving hole 22 and a through hole 21. The through hole 21 is used to avoid the drive device 11 and drive screw 14 of the angle adjustment motor 1. The moving hole 22 provides precise guidance for the sliding of the locking plate 33, ensuring that the locking plate 33 moves only in the preset direction, avoiding deviation or jamming during the locking process, and ensuring the stability and consistency of the locking action. The through hole 21 can provide clearance space for the drive device 11 and drive screw 14. The connecting hole 23 provides a stable foundation for the installation of the locking part 3, ensuring the connection strength between the locking part 3 and the fixed frame plate 2, and preventing the locking part 3 from loosening itself when locking.

[0028] The locking component 3 includes a rotating plate 31, a bolt 32, a locking plate 33, and a limiting slider 34. The bolt 32 passes through the rotating plate 31 and is threaded into the connecting hole 23 on the fixed frame plate 2. The limiting slider 34 is fixed to the bottom of the locking plate 33 and is movably embedded in the moving hole 22 on the fixed frame plate 2. The cooperation between the limiting slider 34 and the moving hole 22 can strictly constrain the movement trajectory of the locking plate 33, so that the locking plate 33 only makes linear movement when locking or unlocking, avoiding poor positioning surface fit due to offset and improving the reliability of locking.

[0029] Bolt 32 and rotating plate 31 are eccentrically connected. The eccentric connection allows the rotating plate 31 to generate a large thrust through the change of eccentricity when it rotates under the drive of bolt 32. The locking plate 33 can be pushed to complete the locking action with a small rotation angle of bolt 32, realizing "small operation amount for large locking force" and improving locking efficiency.

[0030] Two sets of locking components 3 are symmetrically arranged on the fixed frame plate 2. The two locking components 3 are respectively symmetrically positioned on both sides of the angle-adjusting motor 1 to clamp and fix it. The symmetrically arranged locking components 3 apply locking force synchronously from both sides of the angle-adjusting motor 1, so that the motor is subjected to balanced force, avoiding the motor tilting caused by unilateral force, ensuring the verticality and stability of the motor after installation. Moreover, the clamping method on both sides can form a more comprehensive position constraint. No matter whether the vehicle is accelerating, braking or turning, the motor is not easy to shake or shift, enhancing the vibration resistance of the overall structure.

[0031] The mounting plate 15 has symmetrical inclined positioning surfaces 16, and the locking plate 33 has inclined positioning surfaces 35 that cooperate with the positioning surfaces 16. When the inclined surfaces cooperate, they can convert the horizontal thrust of the locking plate 33 into the vertical pressing force on the mounting plate 15, increase the effective locking force, improve the locking firmness, and prevent loosening even under long-term vibration.

[0032] During installation, first install the fixing plate 2 on the car child seat using bolts 32. When installing the angle adjustment motor 1, hold the angle adjustment motor 1 and align the positioning hole 17 of the mounting plate 15 with the positioning rod 24 of the fixing plate 2. Keep the motor axis perpendicular to the plane of the fixing plate 2 and gently push the motor along the direction of the positioning rod 24 so that the drive screw 14 and the drive device 11 are respectively inserted into the through hole 21 of the fixing plate 2. Use a wrench to rotate the bolt 32 of the locking member 3 clockwise. The rotating plate 31 rotates eccentrically with the bolt 32. The eccentrically rotating plate 31 can push the locking plate 33 to slide along the moving hole 22 towards the mounting plate 15. The movement of the locking plate 33 toward the mounting plate 15 enables the positioning surface 16 to fit with the positioning surface 2 35. Observe the gradual fit between the positioning surface 2 35 of the locking plate 33 and the positioning surface 16 of the mounting plate 15. When the two are in complete contact, the locking plate 33 fully presses the mounting plate 15, thereby quickly pressing and locking the mounting plate 15. When the adjusting motor is running to adjust the angle, the drive device 11 is started. The output shaft of the drive device 11 drives the transmission component 18 to run. The transmission component 18 drives the drive screw 14 to rotate synchronously, thereby adjusting the angle of the car child seat.

[0033] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
