[0022] The present invention will be further described in detail below with reference to the embodiments, but the protection scope of the present invention is not limited thereto.

[0023] This utility model relates to a safety seat with manually adjustable protective area, including a seat 1, a backrest 2 at the rear of the seat 1, and a safety guard 3 hinged to the front of the seat 1; the safety guard 3 includes a support rod 31 with one end hinged to the seat, and the other end of the support rod 31 connected to a handle 32; a manual adjustment unit is provided in conjunction with the seat 1 and the safety guard 3, and a locking component is provided in conjunction with the manual adjustment unit.

[0024] In this utility model, the normal direction of travel for the user is defined as "forward";

[0025] The seat 1 and backrest 2 are set up using conventional technology. Those skilled in the art can set them up according to their needs. The safety guard 3 is hinged to the seat 1 facing forward. To be precise, in order to obtain a better riding experience, the hinge point between the seat 1 and the safety guard 3 is located at the bottom of the seat 1 and faces forward.

[0026] In this utility model, the support rod 31 of the safety guard 3 is used to connect the bottom of the seat 1 and the handle 32. The distance between the handle 32 and the backrest 2 can be adjusted by adjusting the position and height of the other end of the support rod 31, thereby accommodating users of different body types.

[0027] Unlike existing technologies, in this invention, the locking mechanism is engaged in the initial state, and the relative positions of the seat 1 and the safety guardrail 3 remain unchanged. However, when the manual adjustment unit is triggered, the locking mechanism is released, thereby allowing the relative positions of the seat 1 and the safety guardrail 3 to be adjusted.

[0028] The following is a detailed embodiment of the manual adjustment unit of this utility model.

[0029] In this embodiment, the manual adjustment unit includes two adjustment buttons 4 on the handle 32. These two adjustment buttons 4 are respectively connected to a set of adjustment mechanisms and a locking element. The user must press them simultaneously to unlock and adjust the safety guard 3.

[0030] Two adjustment buttons 4 are connected to one end of a rigid cable 5. The other end of the rigid cable 5 is connected to a rotating trigger 6. When the adjustment button 4 is pressed, the end of the adjustment button 4 connected to the rigid cable 5 moves forward, that is, the rigid cable 5 is pulled out, and the rotating trigger 6 also rotates by the corresponding angle. Obviously, in order to achieve the rotation of the rotating trigger 6, a rotating shaft 7 is provided between the adjustment button 4 and the handle 32.

[0031] After the trigger 6 is rotated, it acts on one end that cooperates with the compression spring 8. After the compression spring 8 is compressed, the tooth groove 12 at the other end engages with the cooperating gear 9, unlocking it. When both sets of adjustment components are unlocked, the hinge shaft 10 between the seat 1 and the safety guard 3 between the two gears 9 is in an adjustable state, thereby allowing the relative position of the safety guard 3 and the backrest 2 to be adjusted. In fact, in this invention, the gear 9 is stationary, and the tooth groove 12 moves along the gear surface around the hinge shaft 10.

[0032] In this embodiment, considering that it may be difficult to directly attach the rigid cable 5 to the rotating trigger 6, and in fact, the rotating trigger 6 and the rigid cable 5 can also be connected by welding, a collar 11 is provided in the middle of the rotating trigger 6 for easier adjustment. The rigid cable 5 can be connected to the collar 11 in various ways. Obviously, the collar 11 and the end of the compression spring 8 connecting the rotating trigger 6 are respectively set on both sides of the rotating shaft 7, that is, when the rotating trigger 6 is pulled forward, the compression spring 8 moves backward.

[0033] In this embodiment, further considering the need to quickly achieve position limitation after adjustment, a tension spring 13 is provided at the other end of the rotating trigger 6 relative to the compression spring 8. That is, when the compression spring 8 moves backward, the tension spring 13 is pulled open. As long as the user releases the adjustment button 4, the tension spring 13 retracts, turning the rotating trigger 6 back, and the locking member locks and positions the device. If necessary, a damping element can be added to the compression spring 8 or the tension spring 13. This is something that those skilled in the art can easily understand, and they can set it themselves according to their needs.

[0034] In this embodiment, the control of the two compression springs 8 is actually to control the two toothed grooves 12 to engage with the gears 9. The two gears 9 are obviously set at the two ends of the hinge shaft 10 respectively. Therefore, the rotating triggers 6 with corresponding compression springs 8 are stacked vertically and facing opposite directions. To be precise, the two rotating triggers 6 are symmetrically arranged with respect to the central axis of the safety seat on the horizontal projection plane.

[0035] The locking component of the manual adjustment unit includes a fixed wedge 14 disposed on the groove wall of the tooth groove 12. The two ends of the hinge shaft 10 that cooperates with the fixed wedge 14 are provided with fixed grooves 15, and the fixed grooves 15 are concentrically arranged with the gear 9.

[0036] The distance between the mating surface of the fixed wedge 14 and the fixed groove 15 and the bottom of the tooth groove 12 is greater than the distance from the gear surface to the mating surface of the fixed wedge 14 and the fixed groove 15.

[0037] In the specific implementation process, the choice of locking element is diverse. Considering that in this embodiment, when the manual adjustment unit is triggered, the locking element is released and the tooth groove 12 and gear 9 are connected accordingly, a fixing wedge 14 is provided on the groove wall of the tooth groove 12. The fixing wedges 14 on both sides respectively cooperate with the fixing groove 15, and a mating surface, i.e., a locking surface, is provided between them. In the initial state, the tooth groove 12 and gear 9 are disengaged, and the mating surface of the fixing wedge 14 and the fixing groove 15 is engaged, locking. In the initial state and the state when the manual adjustment unit is triggered, the part between the gear surface and the mating surface of the fixing wedge 14 and the fixing groove 15 moves relative to each other in the space between the mating surface of the fixing wedge 14 and the fixing groove 15 and the bottom of the tooth groove 12.

[0038] In this embodiment, the gear surface refers to the tooth surface of the gear 9, that is, the surface that mates with the tooth groove 12.

[0039] Two adjustment buttons 4 and an outward-facing handle 32 are fitted with an anti-slip protective cover 16.

[0040] In this utility model, the anti-slip protective cover 16 can ensure the safety of the user and also serve as a certain indication. That is, when not adjusting, the position of the anti-slip protective cover 16 is the hand position of the handle 32. The user should not place his hand on the adjustment button 4 to avoid accidental touch.

[0041] The support rod 31 is hollow.

[0042] In this invention, on the one hand, in order to reduce the overall weight of the safety seat and avoid the center of gravity shift caused by excessive weight at the front end, and on the other hand, in order to better set up the wiring harness, such as the rigid cable 5, the support rod 31 is set to be hollow to facilitate the setting of the rigid cable 5 and ensure that the center of gravity of the safety seat does not shift.

[0043] The bottom of the chair seat 1 is provided with a base 17, and a lifting mechanism 18 is provided between the base 17 and the chair seat 1.

[0044] In this invention, considering that users need to place both feet on the ground to better ensure the safety of the adjustment process when adjusting manually, a lifting mechanism 18 is provided at the bottom of the seat 1. It can be manually adjusted or connected to a controller, etc. The controller controls the built-in mechanism such as the cylinder to realize the lifting function. This is conventional technology in the field, and those skilled in the art can set it according to their needs.

[0045] Of course, in some practical scenarios, a rotating mechanism is also provided under the base 17, such as a support seat 19, a rotating motor is provided in the middle of the support seat 19 and acts on the base 17, and a matching roller groove 20 and roller 21 are provided on the outer side of the base 17 and the support seat 19, and at least one brake 22 is provided accordingly. This is conventional technology in the field, and those skilled in the art can set it according to their needs.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
