Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to a manually controlled and adjusted automobile seat slide rail, and also relates to the automobile seat thereof. Background Art

[0002] The car seat slide rail is an important and even indispensable part of the car seat structure system, because it is related to the fixation of the car seat, the adjustment of the car seat according to the needs, and the safety of the passengers, etc. For example, by adjusting the slide rail, the desired comfortable space can be provided for the passengers, while the seat movement can be more stable and the impact caused by sudden movement can be reduced; since the slide rail (the lower slide rail is the static slide rail) can basically guarantee the connection strength and rigidity with the car floor, the sitting posture can be maintained in the event of a collision, reflecting safety; since the slide rail can play a good buffering role, it can reduce wear and extend the service life of the seat.

[0003] As is known in the industry, in addition to the more advanced adjustment method of the long slide rail seat, the adjustment methods of the conventional car seat slide rail are mainly electric and manual. Since the technical information of the electric adjustment car seat slide rail can be found in a large number of Chinese and foreign patent documents, the applicant will not repeat it. In a sense, the electric adjustment car seat slide rail evolved from the manual one. Although the electric adjustment car seat slide rail has a dominant position in the current vehicles, the manual adjustment car seat slide rail has always occupied a place and is unlikely to fade out of the market because of its unique advantages. Specifically, the maintenance cost of the electric adjustment car seat slide rail is high, it consumes electricity, and the service life is relatively short; the manual adjustment car seat slide rail has a simple structure, low cost, high adjustment accuracy, and good emergency safety. Especially for some low-end economic vehicles, the mode of configuring the manual adjustment seat slide rail is more suitable in terms of the inquiry ratio. In addition, some vehicle models can be designed to meet specific space layout or mechanical structure requirements by manual adjustment, such as off-road vehicles, trucks, etc., because no complex electronic control system is required, so the manually controlled adjustment car seat slide rail is more practical.

[0004] In the public Chinese patent documents, technical information on car seat slides related to manual control adjustment can be found. For example, CN205130976U recommends "a manual slide for car seats". The design key point of this patent is to set a pair of ball rack assemblies on both sides of the upper guide rail. Each ball rack assembly consists of a ball rack, a steel column and two balls. A steel column slot is set in the middle of the top of the ball rack, and two ball slots are set at the bottom. The steel column and the balls are respectively set in the steel column slot and the ball slot. For another example, CN209600320U provides "a manual sliding car seat slide with external unlocking". By reading paragraphs 0015 to 0017 of the patent specification, it can be seen that it has a large number of parts and a relatively complex structure. For example, as for the joystick support plate, it is necessary to open hole 1, hole 2, bolt clearance hole and fixing hole on it. For example, CN107627909A introduces "a kind of car seat slide rail", which is proposed to solve the problem of a pair of slide rails being locked asynchronously in the prior art. For details, please refer to paragraph 0028 of the patent specification. Then, CN1085560C discloses "a slider for car seats", which is proposed to solve the shortcomings of US patents such as US4964608 (a kind of car seat adjuster) and German patents such as DE3935359 (a kind of device). The so-called shortcomings are: in an accident, the lock may move to the non-locked position under the action of a collision, and then the seat may slide. In other words, CN1085560C has a positive significance in preventing the seat from sliding abnormally under a vehicle collision.

[0005] The structure and working mechanism of the manually adjustable automobile seat slide rail, which are not limited to the above examples, are as follows: the locking teeth formed on both sides of the locking tooth plate are meshed with the lower slide rail groove teeth on the opposite side of the groove wall of the lower slide rail groove formed in the length direction of the lower slide rail (i.e., the static slide rail), and the up and down displacement of the locking tooth plate is controlled by the locking tooth plate actuating shaft arranged on the upper slide rail (i.e., the movable slide rail), and the up and down displacement action of the locking tooth plate actuating shaft is controlled by the locking tooth plate actuating shaft manual operating mechanism also arranged on the upper slide rail. Therefore, when the locking tooth plate actuating shaft manual operating mechanism forces the locking tooth plate actuating shaft to move downward under human or manual operation, the aforementioned locking tooth plate fixed to its lower end driven by the locking tooth plate actuating shaft also moves downward accordingly, so that the locking teeth on the locking tooth plate are separated from the lower slide rail groove teeth, so that the upper slide rail together with the automobile seat fixed thereto can be adjusted, otherwise it is locked. This structural form has the following disadvantages: theoretically, as long as there is no external force acting on the manual operating mechanism of the lock tooth plate actuating shaft, the reaction spring sleeved on the lock tooth plate actuating shaft can ensure that the lock tooth plate actuating shaft is in the upper position, and will not move downward abnormally due to the abnormal movement, causing the lock tooth plate fixed to its lower end to move downward and the lock teeth formed on both sides of the lock tooth plate to separate from the lower slide rail groove teeth. However, since the components of the structural system of the manual operating mechanism of the aforementioned lock plate actuating shaft, such as the unlocking pressure plate of the lock plate actuating shaft, are always in a state of contacting the upper end surface of the lock plate actuating shaft without gap, once the seat passenger accidentally touches the manual unlocking handle of the structural system of the manual operating mechanism of the aforementioned lock plate actuating shaft, which is usually in the shape of a letter "ㄇ", for example, to displace it upward, it will instantly trigger the lock plate actuating shaft together with the aforementioned locking plate to move and cause abnormal unlocking, and finally cause the upper slide rail and the seat to slide abnormally, which may cause unnecessary psychological panic to the seat passenger at the least, and may cause safety hazards at the worst, such as when the upper slide rail slides suddenly and the sliding amplitude is large. Especially in the case of severe bumps, sudden braking, impact, accidental collision and the like during vehicle driving, the manual operating mechanism of the lock plate actuating shaft, which is not controlled by the seat passenger's will, often triggers the lock plate actuating shaft abnormally, and finally causes the uncontrolled displacement of the seat, which will frighten the seat passenger on the one hand, and cause commotion among the people in the vehicle on the other hand.

[0006] From the above description, it can be seen that it is undoubtedly of great positive significance to explore technical measures to ensure that the upper slide rail and the lower slide rail are in a good, stable and reliable locking state even if the passengers accidentally touch the manual operating mechanism of the lock tooth plate actuator shaft during normal driving of the vehicle, and even in situations such as severe bumps and impacts. The technical solution to be introduced below is produced in this context. Summary of the invention

Specifically, when the manual unlocking handle 45 ( Figure 5 (shown), the locking plate actuating shaft 31 is subjected to a downward displacement force, causing the locking plate 34 to separate from the aforementioned lower slide rail locking teeth 1111. At this time, the seat position can be easily moved and adjusted. Since this unlocking method is manually controlled, the driver or passenger can unlock and adjust the seat position within a larger angle range according to actual needs, thereby meeting different riding and driving needs. In addition, the versatility and adaptability of the manually operated controlled slide rail to various working conditions are relatively strong. This is because it is not limited by the power supply or electronic control system, so it can play a stabilizing role in various environments. Whether in extreme weather conditions or when the vehicle power fails, passengers and drivers can adjust the seat position by hand to ensure the comfort and safety they expect.

[0034] Depend on Figure 1As shown, a left stop flange 1113 and a right stop flange 1114 of the lower rail are formed at the lower end of the lower rail groove wall 111 of the lower rail groove 11 of the aforementioned lower rail 1, and the area between the left and right stop flanges 1113 and 1114 of the lower rail constitutes an effective sliding area of ​​the upper rail, and an upper rail sliding stroke limiting foot 24 is formed at the lower sides of the middle part of the aforementioned upper rail 2 in the length direction and at corresponding positions. When the upper rail sliding stroke limiting foot 24 contacts the right side surface of the aforementioned lower rail left stop flange 1113, the upper rail 2 moves to the left to the limit, and when the upper rail sliding stroke limiting foot 24 contacts the left side surface of the aforementioned lower rail right stop flange 1114, the upper rail 2 moves to the right to the limit.

[0035] See also Figure 4 And combined with Figure 1 and Figure 3 The aforementioned ball clearance eliminating mechanism 5 (i.e., clearance eliminating mechanism) includes a ball retainer 51 and balls 52. The ball retainer 51 is arranged in the space between the upper slide rail folding edge 21 of the aforementioned upper slide rail 2 and the outer wall of the lower slide rail 1 facing each other. A plurality of balls 52 are distributed on the left and right ends of the ball retainer 51. The balls 52 enable the upper slide rail 2 and the lower slide rail 1 to form a sliding pair with each other.

[0036] See also Figure 5 And combined with Figures 1 to 4 According to common sense, in actual use, except for the manual unlocking handle 45 and the manual unlocking handle shaft 43, the other upper and lower slide rails 2, 1 and related components are Figure 5The applicant briefly describes the adjustment process of the present invention, taking the seat position adjustment by the seat occupant as an example, the seat occupant lifts the aforementioned manual unlocking handle 45, and the manual unlocking handle 45 drives the aforementioned manual unlocking handle shaft 43, and the manual unlocking handle shaft 43 drives the locking plate actuating shaft pressure plate 42 fixed thereto under the reaction force of the locking plate actuating shaft anti-mistriggered torsion spring 44, so that the locking plate actuating shaft pressure plate 42 applies a downward pressure to the locking plate actuating shaft 31, so that the locking plate actuating shaft 31 moves downward under the reaction force of the aforementioned actuating shaft reset spring 32, and the actuating shaft reset spring 32 is compressed and stores energy at this time. At the same time, since the locking plate actuating shaft 31 moves downward, it drives the locking plate 34 to move downward accordingly, so that the locking teeth 343 on the locking plate 34 exit the locking plate locking groove 1112 downward, and the upper slide rail 2 is in an unlocked state with the lower slide rail 1 at this time, and the seat occupant only needs to adjust the seat to the desired position as needed. After the adjustment is completed, as long as the hand leaves the manual unlocking handle 45, the manual unlocking handle pipe shaft 43 is rotated in the opposite direction to the previous angle under the restoring force of the anti-mis-triggering torsion spring 44 of the aforementioned lock plate actuating shaft, and the aforementioned lock plate actuating shaft pressure plate 42 is also rotated by the manual unlocking handle pipe shaft 43 accordingly, thereby releasing the control of the aforementioned lock plate actuating shaft 31. At the same time, under the restoring force of the actuating shaft reset spring 32, the lock plate actuating shaft 31 moves upward, and the lock plate actuating shaft 31 drives the lock plate 34 to move upward accordingly, and the lock teeth 343 on the lock plate 34 return to the locked state matched with the lock plate locking groove 1112, and the upper slide rail 2 and the seat are also in the locked position. In this locked state, the upper end of the lock plate actuating shaft pressure plate 42 facing downward and the upper end face of the lock plate actuating shaft 31 are restored to maintain an anti-abnormal triggering spacing S of less than 3 mm. That is to say, as long as the anti-abnormal triggering interval S is not confiscated (i.e., not eliminated), abnormal unlocking will not occur and the technical effects mentioned by the applicant in the above technical effect column etc. can be fully reflected.

[0037] The present invention also provides a car seat which is not shown in the figure but can be known according to common professional knowledge, and the car seat is provided with a car seat slide rail which can be adjusted manually.

[0038] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
