Description

Technical Field

[0001] This utility model relates to the field of seat base technology, and in particular to an easily adjustable luxury seat base structure for tourist buses. Background Technology

[0002] With the development of the tourism industry, people have placed higher demands on the comfort of tourist buses. As a key component for enhancing the riding experience, seat design is becoming increasingly important, especially in luxury buses, where the ability to easily adjust seat positions to accommodate the needs of different passengers has become a basic function.

[0003] To achieve convenient seat adjustments, electrically adjustable seats have emerged. Compared to traditional purely manual mechanical adjustments, electric adjustments use a motor-driven transmission mechanism, allowing passengers to easily move the seat forward and backward simply by pressing a button, greatly improving ease of operation. These electrically adjustable seats typically employ gear and rack or lead screw transmission mechanisms to achieve position changes.

[0004] However, in the high-frequency, long-term use environment of tourist buses, existing electrically adjustable seats reveal a common problem. The internal metal transmission components, such as gears and racks, experience continuous friction and wear during repeated meshing. With accumulated use, this wear gradually intensifies, leading to increased transmission clearance and running resistance. Ultimately, this manifests as a less smooth adjustment process, and may even result in jamming or abnormal noises. This degradation in user experience severely impacts the quality expected of a luxury seat, and the root cause lies in the general lack of an integrated design in existing structures capable of continuously and effectively lubricating and maintaining the core transmission components. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easily adjustable luxury seat base structure for tourist buses. This aims to address the issue that the transmission mechanism of easily adjustable luxury seat base structures for tourist buses lacks effective lubrication and maintenance, leading to wear and tear after long-term use, resulting in adjustment jamming and abnormal noise. This utility model aims to provide an easily adjustable luxury seat base structure for tourist buses with an improved structure that effectively solves the aforementioned problems.

[0008] Furthermore, the gear of the moving component meshes with the rack on the base plate; the input end of the oil pump of the lubrication component is connected to the oil reservoir, and the output end of the oil pump is connected to the nozzle through the connecting pipe.

[0009] Preferably, there are two slide rails arranged in parallel, and the rack is arranged between the two slide rails along the length direction.

[0010] Preferably, the axial direction of the drive shaft is perpendicular to the length direction of the rack.

[0011] Preferably, both the motor and the transmission shaft are rotatably mounted on the bracket via bearing seats.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 5 This utility model provides an easily adjustable luxury seat base structure for tourist buses, aiming to solve the problems of complex electric adjustment structures for tourist bus seat bases in the prior art, and the transmission mechanism being prone to wear and tear after long-term use, leading to adjustment jamming.

[0022] like Figure 1 and Figure 4As shown, the easily adjustable luxury seat base structure for tourist buses includes a base plate 1 and a bracket 3 slidably connected to the top of the base plate 1. The base plate 1 serves as the mounting base for the entire device, while the bracket 3 is used to support the seat and realize the reciprocating motion for position adjustment. In order to stably guide and limit the movement of the bracket 3, the structure also includes a limiting component 2. The limiting component 2 includes two parallel slide rails 201 fixedly connected to the top of the base plate 1, and sliders 202 fixedly connected to the bottom of the bracket 3. Each slider 202 slides in cooperation with the corresponding slide rail 201. Through the sliding guide connection between the slide rail 201 and the slider 202, it is ensured that the bracket 3 can only perform a smooth linear reciprocating motion on the top of the base plate 1.

[0023] The movable component 4 is mounted on the bracket 3. The movable component 4 includes a motor 401, a drive shaft 402, and a gear 403. The output end of the motor 401 is connected to one end of the drive shaft 402. The gear 403 is fixedly sleeved on the outer wall of the drive shaft 402. Both the motor 401 and the drive shaft 402 are rotatably mounted on the bracket 3 via bearing seats. The structure also includes a rack 404 fixedly connected to the top of the base plate 1. In the assembled state, the gear 403 on the bracket 3 meshes with the rack 404 on the base plate 1. When the motor 401 operates, it drives the drive shaft 402. The rotating shaft 402 drives the gear 403 to rotate synchronously. The rotating gear 403 rolls along the fixed rack 404, thereby pushing the entire bracket 3 together with the moving component 4 installed on the bracket 3 to move precisely linearly along the direction of the slide rail 201. To ensure the smoothness of the transmission, the axis of the drive shaft 402 is perpendicular to the length direction of the rack 404. At the same time, the rack 404 is arranged between the two slide rails 201 along the length direction. This structural layout ensures the balanced application of driving force and high stability during the movement of the bracket 3.

[0024] As a further optimization of the transmission mechanism, the easily adjustable luxury seat base structure for the tour bus also includes a lubrication assembly 5. The lubrication assembly 5 automatically lubricates the meshing parts of the gear 403 and rack 404 in the moving assembly 4 to reduce wear and ensure smooth long-term operation; please refer to... Figure 1 and Figure 3 The lubrication assembly 5 is mounted on the bracket 3. The lubrication assembly 5 includes an oil reservoir 502, an oil pump 504, a connecting pipe 505, and a nozzle 506. The oil reservoir 502 is used to store lubricating oil. The input end of the oil pump 504 is connected to the bottom of the oil reservoir 502. The output end of the oil pump 504 is connected to the nozzle 506 through the connecting pipe 505. The nozzle of the nozzle 506 is precisely oriented towards the outer wall of the gear 403. The lubricating oil in the oil reservoir 502 is pumped to the nozzle 506 by the oil pump 504 and sprayed onto the tooth surface of the gear 403.

[0025] In a preferred embodiment, in order to ensure the cleanliness of the lubricating oil and prevent impurities from clogging the oil passage or nozzle 506, the lubrication assembly 5 also includes a filter cartridge 503. The filter cartridge 503 is disposed between the oil reservoir 502 and the input end of the oil pump 504. The lubricating oil is filtered by the filter cartridge 503 before entering the oil pump 504.

[0026] As another preferred embodiment, in order to facilitate the replenishment of lubricating oil into the oil reservoir 502, the lubrication assembly 5 also includes a cover 501, which is sealed to the top opening of the oil reservoir 502 by means of a threaded connection.

[0027] As a specific installation method, the oil reservoir 502 is fixed to the side wall of the bracket 3. This layout facilitates observation of the oil level and the addition of oil.

[0028] Working principle: When the seat position needs to be adjusted, the motor 401 in the moving assembly 4 is activated. The motor 401 drives the gear 403 to rotate through the transmission shaft 402. Since the gear 403 is always meshed with the rack 404 fixed on the base plate 1, the rotating gear 403 will roll along the length of the rack 404, thereby pushing the entire bracket 3 to move linearly on the top of the base plate 1. During the entire movement of the bracket 3, the slider 202 at the bottom of the bracket 3 always slides in the slide rail 201 at the top of the base plate 1. The sliding cooperation between the slider 202 and the slide rail 201 provides precise guidance and stable support for the bracket 3, ensuring a smooth and stable adjustment process. When the seat adjustment mechanism is used for a long time or requires lubrication according to the preset program, the oil pump 504 in the lubrication assembly 5 is started. The oil pump 504 draws out the lubricating oil from the oil reservoir 502. When the lubricating oil flows through the filter cartridge 503, impurities are filtered out. The clean lubricating oil is delivered to the nozzle 506 through the connecting pipe 505 and sprayed evenly on the tooth surface of the gear 403 through the nozzle 506, providing sufficient lubrication for the meshing of the gear 403 and the rack 404, effectively reducing friction and wear during the transmission process.
