Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to an adjustable hammer seat assembly for the rear seats of an automotive seat. Background Technology

[0002] The rear seat hammer assembly is the core structure of a car seat adjustment system. It is usually made of a high-strength metal or engineering plastic frame and is equipped with a precision adjustment mechanism. When the locking mechanism inside the hammer assembly is unlocked, the backrest can rotate freely within a certain angle range and automatically locks after reaching the appropriate position, ensuring that the seat remains stable during vehicle movement and providing passengers with a comfortable and safe seating posture. At the same time, it can effectively disperse the impact force in the event of a collision, enhancing the safety and reliability of the seat.

[0003] Chinese patent CN219687134U discloses a hammer assembly for adjusting the rear seat of an automobile, including a base and a bracket assembly. Side plate assemblies are provided on both sides of the bottom end of the base, and fixing components are provided inside the side plate assemblies. The bracket assembly is provided on the top end of the base. The bracket assembly includes a top frame, connecting pieces, extension rods, and threaded walls. Connecting pieces are provided on both sides of the bottom end of the top frame, and extension rods are provided at the bottom end of the connecting pieces. Threaded walls are provided around the outer perimeter of the extension rods. In this hammer assembly for adjusting the rear seat of an automobile, connecting pieces are fixed to the bottom ends of the top frame, and a corresponding extension rod is fixed to the bottom end of each set of connecting pieces. Threaded walls cover the outer perimeter of the extension rods. The top frame is lifted and aligned with the inside of the base through the threaded walls on the outer perimeter of the extension rods, fixing the base and top frame together. This allows for easy disassembly by the user via threaded connection. In case of equipment damage, usable parts can be retained for recycling, effectively reducing cost losses.

[0004] Existing related technologies often have the following drawbacks: the device bracket assembly and the base are connected by threads, but the threaded connection is prone to loosening under the continuous vibration of the vehicle, causing relative displacement between the bracket assembly and the base. This not only affects the accuracy of seat adjustment, but may also cause the seat back to shake, reducing riding comfort and safety. At the same time, if the threads are not accurately aligned or the machining error of the internal threaded hole of the base is large, it is very easy to cause the threads to strip or be damaged, which not only increases the difficulty of installation, but also affects subsequent disassembly and maintenance. Therefore, this utility model provides a rear seat adjustment hammer base assembly for automobiles. Utility Model Content

[0005] The purpose of this application is to provide a rear seat adjustment hammer assembly for automobiles in order to solve the problems mentioned above.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rear seat adjustment hammer assembly for automobiles, including a hammer frame, a connecting bracket provided on the top surface of the hammer frame, and a limiting and fixing component connected to the connecting bracket on the top surface of the hammer frame.

[0007] The limiting and fixing assembly includes a circular mounting base, a connecting crossbar, a movable slider, a fixing pin, a first connecting through hole, a second connecting through hole, a spacer, a return spring, a limiting hole, and a connecting protrusion. Two circular mounting bases are fixedly installed on the top surface of the hammer base frame. The bottom end of the connecting bracket is inserted into the interior of the circular mounting base. A positioning component connected to the circular mounting base is provided on the outer surface of the connecting bracket. A connecting crossbar is fixedly installed on the outer surface of the circular mounting base. Two movable sliders are provided inside the connecting crossbar, and fixing pins are fixedly installed at the ends of the two movable sliders that are far apart from each other. The outer surface of the circular mounting base has a connecting through hole one corresponding to the fixing pin. The outer surface of the connecting bracket near the bottom end has a connecting through hole two corresponding to the connecting through hole one. One end of the fixing pin passes through the connecting through hole one and the connecting through hole two in sequence. A partition block is fixedly installed inside the connecting crossbar near the middle. A return spring is fixedly installed at the end of the movable slider away from the fixing pin. One end of the return spring is fixed to one side of the partition block. A limit hole is opened on the top surface of the connecting crossbar. A connecting protrusion is fixedly installed on the top surface of the movable slider. One end of the connecting protrusion passes through the inside of the limit hole.

[0008] The aforementioned components achieve the following effect: personnel can press the L-shaped mounting plate, causing it to move the connecting protrusion, which in turn pushes the movable slider and the fixing pin into the circular mounting base. This facilitates the complete embedding of the connecting bracket into the circular mounting base. Once the circular mounting base is fully embedded, personnel release the L-shaped mounting plate. At this time, the return spring releases its elasticity, pushing the movable slider so that the fixing pin passes through the connecting through hole one and the connecting through hole two, firmly locking the connecting bracket onto the hammer base frame, greatly improving the stability after installation.

[0009] Preferably, the positioning component includes positioning grooves and positioning protrusions. The inner wall of the circular mounting base has two symmetrically formed positioning grooves. The connecting bracket has two positioning protrusions corresponding to the positioning grooves fixedly installed near the bottom outer surface. The positioning protrusions are inserted into the inside of the positioning grooves.

[0010] The effect achieved by the above components is as follows: through the cooperation of the positioning protrusion and the positioning groove in the positioning component, the installation position of the connecting bracket can be quickly and accurately determined when the connecting bracket is inserted into the circular mounting base, reducing the alignment time and operation difficulty during the installation process, while effectively avoiding the installation offset of the connecting bracket, providing a stable foundation for subsequent fixation, and ensuring the installation accuracy of the seat adjustment mechanism.

[0011] Preferably, an L-shaped mounting plate is fixedly installed on the top of the connecting protrusion.

[0012] The effects achieved by the above components are as follows: the L-shaped mounting plate provides an easy structure for operators to apply force. Whether installing or removing the connecting bracket, pressing or lifting the L-shaped mounting plate can easily drive the connecting protrusion, moving slider and other components to move, making the operation more labor-saving and convenient. In addition, the L-shaped mounting plate can also serve as a transition structure for connecting with other components of the seat, enhancing the connection stability between the components and the overall seat.

[0013] Preferably, auxiliary adjustment wheels are provided on the left and right sides of the hammer base frame.

[0014] The effect achieved by the above components is as follows: by setting auxiliary adjustment wheels, the friction of the hammer base frame is greatly reduced during movement. When the seat position needs to be adjusted, the operator can easily push the hammer base frame to move back and forth and left and right, reducing the labor intensity of adjustment operations and improving the flexibility and convenience of seat adjustment. It is especially suitable for scenarios that require frequent adjustment of seat position.

[0015] Preferably, a flexible rubber pad is fixedly installed on the top surface of the L-shaped mounting plate.

[0016] The effect achieved by the above-mentioned components is to improve the comfort of the user's hands when pressing, thanks to the flexible rubber pads.

[0017] Preferably, the circular mounting base, connecting crossbar, and fixing pin are all made of alloy steel.

[0018] The effects achieved by the above components are as follows: alloy steel material has high strength, high wear resistance and good fatigue resistance. The circular mounting base, connecting crossbar and fixing pin are made of alloy steel, which can withstand the frequent force and friction during seat adjustment, and is not prone to deformation, wear or breakage, thus extending the service life of the components.

[0019] In summary:

[0020] 1. In this utility model, the setting of the limiting and fixing component achieves a balance between high efficiency and stability in the installation and disassembly of the connecting bracket. During installation, pressing the L-shaped mounting plate will move the sliding slider and the fixing pin to make room for the connecting bracket to be inserted into the circular mounting seat. After insertion, releasing the L-shaped mounting plate will cause the return spring to quickly drive the fixing pin through the connecting through hole, firmly locking the connecting bracket, which greatly shortens the installation time. During disassembly, it can also be easily separated by pressing the L-shaped mounting plate. The operation is simple and quick. Moreover, under complex working conditions such as vehicle vibration, this component can still ensure the stability of the seat adjustment mechanism through the tight cooperation between the fixing pin and the connecting through hole, effectively improving the accuracy of seat adjustment and passenger safety.

[0021] 2. In this utility model, the positioning protrusion and positioning groove in the positioning component can play a precise guiding and positioning role during the connection process between the connecting bracket and the limiting and fixing component, avoiding problems such as positional deviation during the installation of the connecting bracket, and ensuring that the connecting bracket can be accurately connected to the limiting and fixing component.

[0027] Reference Figures 1-3 As shown, this utility model provides a technical solution: a rear seat adjustment hammer seat assembly for automobiles, including a hammer seat frame 1, a connecting bracket 2 on the top surface of the hammer seat frame 1, auxiliary adjustment wheels 6 on the left and right sides of the hammer seat frame 1, and a limiting and fixing component 3 connected to the connecting bracket 2 on the top surface of the hammer seat frame 1. The hammer seat frame 1 provides stable support for the basic structure of the entire assembly. The connecting bracket 2 can be used to connect other parts of the seat to realize the transmission of seat adjustment function. The auxiliary adjustment wheels 6 reduce friction when adjusting the seat position, making the adjustment process easier and smoother, and improving the convenience of user operation. The limiting and fixing component 3 can effectively fix and limit the connecting bracket 2, ensuring that the seat remains stable after adjustment, improving the safety and comfort of riding.

[0028] Reference Figures 1-3As shown, the limiting and fixing assembly 3 includes a circular mounting base 301, a connecting crossbar 302, a movable slider 303, a fixing pin 304, a first connecting through hole 305, a second connecting through hole 306, a spacer 307, a return spring 308, a limiting hole 309, and a connecting protrusion 310. Two circular mounting bases 301 are fixedly installed on the top surface of the hammer base frame 1. The bottom end of the connecting bracket 2 is inserted into the interior of the circular mounting base 301. The outer surface of the connecting bracket 2 is provided with a positioning assembly 4 that connects to the circular mounting base 301. The circular mounting base 301 provides a precise installation position for the connecting bracket 2, ensuring the accuracy of the connection. The positioning groove 401 and the positioning protrusion 402 in the positioning assembly 4 further enhance the stability and positioning accuracy of the connecting bracket 2 during installation, preventing it from shifting during installation and ensuring the installation quality of the entire assembly.

[0029] Reference Figures 1-3 As shown, the positioning component 4 includes positioning grooves 401 and positioning protrusions 402. Two positioning grooves 401 are symmetrically opened on the inner wall of the circular mounting base 301. Two positioning protrusions 402 corresponding to the positioning grooves 401 are fixedly installed on the outer surface of the connecting bracket 2 near the bottom end. The positioning protrusions 402 are inserted into the inside of the positioning grooves 401. By setting the positioning protrusions 402 to be inserted into the inside of the positioning grooves 401, the connecting bracket 2 and the circular mounting base 301 can be quickly and accurately fixed together during installation. At the same time, during the use of the seat, the movement of the connecting bracket 2 is effectively restricted, and the reliability of the seat adjustment mechanism is improved.

[0030] Reference Figures 1-3 As shown, a connecting crossbar 302 is fixedly mounted on the outer surface of the circular mounting base 301. Two movable sliders 303 are disposed inside the connecting crossbar 302, and each of the two movable sliders 303 has a fixing pin 304 fixedly mounted at its far-away ends. A first connecting through hole 305 corresponding to the fixing pin 304 is formed on the outer surface of the circular mounting base 301. A second connecting through hole 306 corresponding to the first connecting through hole 305 is formed on the outer surface of the connecting bracket 2 near its bottom end. One end of the fixing pin 304 passes through the first connecting through hole 305 and the second connecting through hole 306 in sequence. 6. The circular mounting base 301, connecting crossbar 302, and fixing pin 304 are all made of alloy steel. The circular mounting base 301, connecting crossbar 302, and fixing pin 304 made of alloy steel ensure that the components have high strength and good wear resistance, and can withstand various forces and frictions during seat adjustment. The fixing pin 304 passes through the first connecting through hole 305 and the second connecting through hole 306, and firmly connects the connecting bracket 2 to the circular mounting base 301, so that the seat can be stably fixed after being adjusted to a suitable position and will not easily loosen.

[0031] Reference Figures 1-3As shown, a spacer 307 is fixedly installed near the center of the connecting crossbar 302.

The L-shaped mounting plate 5 makes it easy for personnel to press and improves the convenience of moving the movable slider 303. The flexible rubber pad 7 can improve hand comfort.

[0032] Working principle: When the connecting bracket 2 needs to be installed, the operator first aligns its bottom end with the circular mounting base 301 and inserts it. The cooperation between the positioning protrusion 402 and the positioning groove 401 in the positioning assembly 4 can accurately guide the connecting bracket 2 to the predetermined position, effectively avoiding installation deviation. During the process of the connecting bracket 2 penetrating the circular mounting base 301, the operator can press the L-shaped mounting plate 5, which drives the connecting protrusion 310, thereby pushing the moving slider 303 and the fixing pin 304 into the circular mounting base 301. This facilitates the complete embedding of the connecting bracket 2 into the circular mounting base 301. After the circular mounting base 301 is embedded in place, the operator releases the L-shaped mounting plate 5. At this time, the return spring 308 releases its elasticity, pushing the moving slider 303 and the fixing pin 304 into the circular mounting base 301. The movable slider 303 allows the fixing pin 304 to pass through the connecting through hole 305 and the connecting through hole 306, firmly locking the connecting bracket 2 onto the hammer seat frame 1, greatly improving the stability after installation. During disassembly, personnel only need to press the L-shaped mounting plate 5 again to make the movable slider 303 drive the fixing pin 304 to disengage from the connecting through hole, thus easily separating the connecting bracket 2. The device can flexibly assist the movement of the hammer seat frame 1 through the auxiliary adjustment wheel 6, making seat adjustment operations easier and less strenuous. At the same time, through the positioning and elastic locking structure, the connecting bracket 2 can be quickly and accurately installed and firmly fixed, maintaining a reliable connection even in vehicle vibration environments. The disassembly operation is simple and quick, effectively reducing the difficulty of installation and maintenance.
