[0068] Although the present invention is illustrated and described with reference to specific embodiments, the invention should not be limited to the details shown. Rather, various modifications can be made to these details within the scope of equivalent solutions of the claims without departing from the invention.

[0069] The directional descriptions such as "front", "rear", "upper", and "lower" involved in this document are only for convenience of understanding. The present invention is not limited to these directions but can be adjusted according to the actual situation.

[0070] First, refer to Figures 1 to 3 The vehicle 200 according to the present application will be described as a whole. In an embodiment of the present application, the vehicle 200 is a child safety seat, but is not limited thereto. The present application is applicable to any vehicle 200 that needs to support the foot 100.

[0071] As shown in the figure, the vehicle 200 includes a base 210 and a seat 220. The base 210 is the part for fixing the vehicle 200 to the car seat, and the seat 220 is the part for carrying the occupant (i.e., the child). The support foot 100 is installed below the base 210, more specifically, on the front side below the base 210, and is used to support the base 210 on the car floor so as to prevent the child safety seat from tipping forward when the car jolts.

[0072] In one embodiment, the support foot 100 is connected to the base 210 through a telescopic bracket 170 (see Figure 5 ), and thus can move along the longitudinal direction (front-rear direction) relative to the base 210 so as to extend out of the base 210 or retract below the base 210. It should be understood that the support foot 100 can also be directly connected to the base 210.

[0073] The support foot 100 can be covered with a cover 160 above it. A cover indicating portion 165 can be provided on the top surface of the cover 160 to facilitate the user to observe whether the support foot 100 extends completely out of the base 210. The cover indicating portion 165 is provided at the rear end of the cover 160, and only when the cover 160 extends completely out, the cover indicating portion 165 will move out of the base 210. The cover indicating portion 165 can have a color that is easy to observe, such as green or other colors with a strong contrast to the support foot 100, so as to attract the user's attention.

[0074] In Figure 1 's state, the support foot 100 extends completely out of the base 210, so the cover indicating portion 165 can be seen. In Figure 2 's state, the support foot 100 does not extend completely out of the base 210, so the cover indicating portion 165 cannot be seen.

[0075] A hollow portion or a transparent window 166 (seeFigure 4 ) so that the user can observe the indicator 110 provided on the support leg 100. The indicator 110 is used to indicate whether the bottom end of the support leg 100 touches the ground, and its structure and principle will be described in detail below.

[0076] In one embodiment, the support leg 100 can be adjusted in length. Specifically, the support leg 100 includes a support upper tube 101 with an indicating end and a support lower tube 102 with a contact end. The support upper tube 101 is sleeved on the support lower tube 102 and has corresponding positioning means (such as engaging members or pins) to allow adjustment of the overall length of the support leg 100.

[0077] The upper end of the support leg 100 (referred to as the indicating end) is connected to the bracket 170 (or directly connected to the base 210 in an embodiment without the bracket 170). The lower end of the support leg 100 (referred to as the contact end) is used to contact the ground. In one embodiment, a fixed seat 140 may be provided at the contact end to facilitate the assembly of the contact indicating mechanism of the present application. In other embodiments, the fixed seat 140 can be integrated into the support leg 100 to form a single component with the support leg 100.

[0078] In one embodiment, the support leg 100 can rotate as a whole with the indicating end as the rotation axis to the lower side of the base 210, as Figure 3 shown. In this way, the support leg 100 can be completely folded into the base 210 to facilitate the handling of the vehicle 200.

[0079] Now turn to Figures 4 to 5 . As shown in the figure, the bracket 170 for connecting the support leg 100 to the base 210 includes a sliding mechanism 171 and a support leg rotation shaft 175. Among them, the sliding mechanism 171 is a scissor link and / or a slide rail, and a spring can be provided on the sliding mechanism 171 to bias the support leg 100 towards the lower side of the base 210. The front end of the bracket 170 can be provided with a support leg rotation shaft 175 extending in the left-right direction (i.e., horizontally), and the upper end of the support leg 100 is mounted on the support leg rotation shaft 175 to allow the support leg 100 to rotate as a whole to the lower side of the base 210 (as Figure 3 shown).

[0080] From Figure 4 and Figure 5 it can be clearly seen that the indicator 110 of the contact indicating mechanism is exposed to the user's line of sight through the hollow portion or the transparent window 166 on the decorative cover 160 for the user to observe.

[0081] Now refer to Figures 6 to 8 to specifically describe the specific structure of the contact indicating mechanism according to the present application and how it is installed on the support leg 100.

[0082] As shown in the figure, the contact indication mechanism includes an indicator 110, a driving member 130, a cable sleeve 155, and a cable 150. In some embodiments, the contact indication mechanism may further include a mounting member 120, a first elastic member 182, a first screw 181( Figure 9A , Figure 9B ), a second elastic member 183, and a second screw 184.

[0083] The indicator 110 is disposed at the indicating end of the support leg 100 through a lateral movable shaft 114 and can rotate around the movable shaft 114 between a first position and a second position. For example, the first position corresponds to the state where the support leg does not contact the ground, and the second position corresponds to the position where the support leg has contacted the ground. In one embodiment, a first area 111 and a second area 112 are circumferentially provided on the columnar outer periphery of the indicator 110 (see Figure 9A , Figure 9B ). When the support leg 100 is in its non-ground contact position, the first area 111 is exposed outside the hollow portion or the transparent window 166; when the support leg 100 is in its ground contact position, the second area 112 is exposed outside the hollow portion or the transparent window 166. For example, the first area 111 may be red, and the second area 112 may be green, or the second area 111 and the second area 112 may be depicted with different marks (such as dots, slashes, or other patterns), as long as they can be used to indicate whether the support leg 100 is in contact with the ground. The embodiments of the present application do not limit the representation methods of the first area and the second area. The shapes of the first area 111 and the second area 112 may correspond to the shape of the hollow portion or the transparent window 166.

[0084] The movable shaft 114 can be directly erected at the indicating end of the support leg 100 or can be installed on the indicating end through the mounting member 120. For example, the movable shaft 114 is erected on two relatively vertical walls of the mounting member 120, and the mounting member 120 is fixed to the indicating end. In the embodiment shown in the figure, the support leg 100 is a hollow tubular member, and the mounting member 120 can be fixed to the inside of the indicating end. However, the present application is not limited thereto.

[0085] The first elastic member 182 is disposed between the indicator 110 and the first end 156 of the cable sleeve and abuts against the indicator to bias the indicator 110 towards the first position.

[0086] The first side of the indicator 110 has a first receiving portion 113 for receiving the first end 151 of the cable. The first elastic member 182 and the second side of the indicator 110 abut against one end of the first elastic member 182. The other end of the first elastic member 182 is fixed to the indicating end. In one embodiment, the first side of the indicator 110 is relative to the second side.

[0087] The driving member 130 is at least partially disposed in the contact end of the support leg 100, and includes a contact portion 131 extending outwardly along the vertical direction toward the outside of the contact end. The driving member 130 can move relative to the contact end between an extended position where the contact portion 131 extends out of the contact end and a retracted position where the contact portion 131 retracts into the contact end.

[0088] More specifically, the driving member 130 may include a shoulder 135 and a column hole 132. The shoulder 135 is located within the contact end of the support leg 100 and extends substantially horizontally. The two contact portions 131 respectively extend outwardly along the vertical direction from the two horizontal ends of the shoulder 135 out of the contact end. The column hole 132 is formed in the shoulder 135 and can be slidably sleeved on a column 141 extending inwardly from the bottom of the contact end.

[0089] In one embodiment, a second elastic member 183 is disposed between the driving member 130 and the contact end of the component. The second elastic member 183 biases the driving member 130 toward the extended position. The second elastic member 183 may be a helical spring. The second elastic member 183 is sleeved on the column 141. One end of the second elastic member 183 abuts against the inner side of the second screw 184, and the other end abuts against the shoulder 135 to bias the driving member 130 toward the extended position. It should be understood that the setting manner of the second elastic member 183 is not limited to this, as long as the driving member 130 is biased toward the extended position.

[0090] The driving member 130 further includes a cable sleeve 155 mounting portion (i.e., the second accommodating portion 133), which extends inwardly along the vertical direction from the center of the shoulder 135, and is in the form of a groove and has a shape corresponding to the second end 157 of the cable sleeve, for fixing the second end 157 of the cable sleeve. It should be understood that the form of the cable sleeve mounting portion is not limited to this, but can be changed accordingly according to the form of the second end of the cable sleeve.

[0091] The fixing base 140 is a substantially flat member extending along the horizontal and vertical directions. In an embodiment where the fixing base 140 is provided as a separate component, the lower end (contact end) of the support leg 100 may be an open end, and the fixing base 140 is used to close the open end. The column 141 and the third accommodating portion 142 are disposed on the inner side of the fixing base 140. Through holes are formed in the fixing base 140 so that the contact portions 131 of the driving member 130 extend out of the support leg 100. As shown above, the fixing base 140 may be integrated into the support leg 100 as an integral component.

[0092] The cable sleeve 155 extends substantially vertically between the indicating end and the contact end of the support leg 100. The cable sleeve 155 includes a first end 156 of the cable sleeve fixed to the indicating end and a second end 157 of the cable sleeve fixed to the driving member 130. The cable sleeve 155 may be made of materials such as rubber or plastic, which has a certain flexibility and can be bent, but its length basically does not change.

[0093] In one embodiment, both the first end 156 and the second end 157 of the cable sleeve are in the form of a hammer head with enlarged diameters at both ends. It should be understood that the first end 156 and the second end 157 of the cable sleeve can also be in other forms, such as external threads, elastic snap-fit components, or directly welded to the indicating end and the driving member 130.

[0094] The cable 150 extends substantially vertically between the indicating end and the contact end of the support leg 100 and is slidably sleeved in the cable sleeve 155. The cable 150 includes a first cable end 151 and a second cable end 152 extending from both ends of the cable sleeve 155, wherein the first cable end 151 is fixed to the indicator 110 and can drive the indicator 110 to rotate around the movable shaft 114, and the second cable end 152 is fixed to the contact end. Further, the second cable end 152 is fixedly connected to the base 140. The cable 150 is made of, for example, steel wire, nylon wire or carbon fiber, which has a certain flexibility and can be bent, but its length basically does not change.

[0095] In one embodiment, both the first cable end 151 and the second cable end 152 are in the form of a hammer head with enlarged diameters at both ends. It should be understood that the first cable end 151 and the second cable end 152 can also be in other forms, such as external threads, knots, or directly welded to the indicating end and the contact end.

[0096] Now refer to Figures 9A to 10B Describe the operation of the contact indicating mechanism of the present application.

[0097] As shown in the figure, in Figure 9A and Figure 10A shown, the indicator 110 is in its first position and the driving member 130 is in its extended position. The first region 111 of the indicator 110 faces upward (i.e., the position of the hollow portion or the transparent window 166 on the decorative cover 160) to indicate that the support leg 100 is not in contact with the ground. Due to the biasing action of the first elastic member 182 and the second elastic member 183, in the absence of external forces, the indicator 110 and the driving member 130 tend to remain in Figure 9A and Figure 10A shown positions.

[0098] In Figure 9B and Figure 10BIn the shown case, the contact end has contacted the ground. The contact portion 131 of the driving member 130 is exposed outside the support leg 100, so it receives the pressure from the ground first. Thus, it moves to its retracted position by overcoming the biasing force of the second elastic member 183. Since the second end of the cable sleeve is fixed to the driving member 130, the driving member 130 drives the second end 157 of the moving cable sleeve away from the contact end (i.e., moves upward). At the same time, since the second end 152 of the cable is fixed to the contact end, the second end 152 of the cable does not move away from the contact end, that is, does not move upward. In this way, it is equivalent to the second end 152 of the cable protruding a certain length from the second end 157 of the cable sleeve. As described above, the lengths of the cable and the cable sleeve are basically unchanged, that is, the length of the part of the cable 150 in the cable sleeve 155 is basically unchanged. Thus, when the second end 152 of the cable protrudes a certain length from the second end 157 of the cable sleeve, the first end 151 of the cable will retract a corresponding length into the first end 156 of the cable sleeve. Since the first end 156 of the cable sleeve is fixed to the indicating end of the support leg 100, this causes the cable 150 to slide relative to the cable sleeve 155 towards the contact end, thereby driving the indicator 110 to rotate from its first position to the second position.

[0099] In some other embodiments, the indicator 110 can be arranged to move linearly instead of rotating. For example, the indicator 110 is arranged in the indicating end through a slide rail and can slide between the second position and the first position. Without external force, the indicator 110 is biased towards the first position. When the contact end contacts the surface, the cable 150 (specifically the first end 151 of the cable) will drive the indicator 110 to move to the second position by overcoming the biasing force. The slide rail can be arranged horizontally, and then the vertical movement of the cable 150 is converted into horizontal movement through a pulley at the indicating end. The slide rail can also be arranged vertically, and then a hollow portion or a transparent window 166 is opened on the vertical surface of the decorative cover 160.

[0100] Figures 11A to 11B An explanation of the technical principle of the present application is given. When the cable sleeve 155 changes from the Figure 11A shown non-contact state to the Figure 11B shown contact state, the second end 157 of the cable sleeve is pushed upward. However, since the first end 156 of the cable sleeve is fixed, the cable sleeve 155 bends (the degree of bending is exaggerated in the figure). For the cable 150, since it is sleeved in the cable sleeve 155, it must extend along the bending path of the cable sleeve 155. Therefore, the extension path of the cable 150 from the indicating end to the contact end actually becomes longer. Since the second end 152 of the cable is fixed to the contact end, the first end 151 of the cable is forced to contract inward.

[0101] Although Figure 11AIt is shown that the cable sheath 155 and the cable 150 extend substantially along a straight line. However, it should be understood that in the non-contact state, the cable sheath 155 and the cable 150 are not necessarily straight. In fact, the cable sheath 155 and the cable 150 can also be bent in the non-contact state and become more bent in the contact state, and their functions can still be achieved. The advantage of this characteristic is that the cable 150 and the cable sheath 155 can adapt to support legs 100 of various lengths. For example, the lengths of the cable 150 and the cable sheath 155 can be designed to correspond to the maximum length of the support leg 100. When the support leg 100 is adjusted and shortened, the cable 150 and the cable sheath 155 are bent and connected between the two ends of the support leg 100, and the function of indicating contact can still be achieved.

[0102] In summary, the present application provides a contact indication mechanism that can intuitively display whether one end of the support leg touches the ground at the other end of the support leg. Moreover, the contact indication mechanism of the present application allows the length of the support leg to change, and the contact indication function can still be achieved. It should be understood that although the support leg is shown in the embodiment, the contact indication mechanism of the present application can be applied to various components of various shapes.

[0103] The present application also provides a support leg that has a contact indication mechanism and an extension indication mechanism, and can prompt the user of the extension state and the ground contact state of the support leg.

[0104] The present application also provides a vehicle that has a support leg according to the present application, and the support leg can be folded and retracted under the base of the vehicle.

[0105] Although the preferred embodiments have been shown and described herein, it should be understood that these embodiments are given by way of example only. Those skilled in the art will envision many variations, changes, and substitutions without departing from the spirit of the invention. Therefore, the appended claims are intended to cover all such variations that fall within the spirit and scope of the invention.
