[0078] The descriptions of directions such as “front”, “back”, “up” and “down” in this document are only for the convenience of understanding. The present invention is not limited to these directions but can be adjusted according to actual conditions.

[0079] First refer to Figures 1 to 3 The vehicle 200 according to the present application is generally described. In the embodiment of the present application, the vehicle 200 is a child safety seat, but it is not limited thereto, and the present application is applicable to any vehicle 200 that requires a support leg 100 .

[0080] As shown in the figure, the carrier 200 includes a base 210 and a seat 220, wherein the base 210 is a part for fixing the carrier 200 to the car seat, and the seat 220 is a part for carrying the occupant (i.e., child). The support foot 100 is installed under the base 210, more specifically, installed at the front side under the base 210, and is used to support the base 210 on the floor of the car to prevent the child safety seat from tipping forward when the car bumps.

[0081] In one embodiment, the support leg 100 is supported by a retractable bracket 170 (see Figure 5 ) is connected to the base 210, so that it can move along the longitudinal direction (front-rear direction) equivalent to the base 210, so as to extend from the base 210 or retract under the base 210. It should be understood that the support foot 100 can also be directly connected to the base 210.

[0082] The support foot 100 may be covered with a decorative cover 160, and a decorative cover indicator 165 may be provided on the top surface of the decorative cover 160, so that the user can observe whether the support foot 100 is fully extended from the base 210. The decorative cover indicator 165 is provided at the rear end of the decorative cover 160, and the decorative cover indicator 165 will move out of the base 210 only when the decorative cover 160 is fully extended. The decorative cover indicator 165 may have a color that is easily observed, such as green or other colors that have a strong contrast with the support foot 100, so as to attract the user's attention.

[0083] exist Figure 1 In the state, the support foot 100 is fully extended from the base 210, so that the decorative cover indicator 165 can be seen. Figure 2 In the state, the support foot 100 is not fully extended from the base 210, so the decorative cover indicator 165 cannot be seen.

[0084] The front end of the decorative cover 160 may also be provided with a hollow portion or a transparent window 166 (see Figure 4 ), so that the user can observe the indicator 110 disposed on the support leg 100. The indicator 110 is used to show whether the bottom end of the support leg 100 touches the ground, and its structure and principle will be described in detail below.

[0085] In one embodiment, the support leg 100 can be adjusted in length. Specifically, the support leg 100 includes a support leg upper tube 101 having an indicating end and a support leg lower tube 102 having a contact end, and the support leg upper tube 101 is sleeved on the support leg lower tube 102 and has a corresponding positioning device (such as a snap-fit ​​or a latch) to allow the overall length of the support leg 100 to be adjusted.

[0086] 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 fixing seat 140 may be provided at the contact end to facilitate assembly of the contact indicating mechanism of the present application. In other embodiments, the fixing seat 140 may be integrated into the support leg 100 and become one component with the support leg 100.

[0087] In one embodiment, the support leg 100 can be rotated as a whole to the bottom of the base 210 with the index end as the rotation axis. Figure 3 In this way, the support leg 100 can be completely folded into the base 210 to facilitate carrying the carrier 200.

[0088] Now go to Figures 4 to 5As 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. The sliding mechanism 171 is a scissor-type connecting rod and / or a slide rail, and the sliding mechanism 171 may be provided with a spring to bias the support leg 100 toward the bottom of the base 210. The front end of the bracket 170 may be provided with a support leg rotation shaft 175 extending in the left-right direction (i.e., transverse direction), 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 bottom of the base 210 (e.g., Figure 3 shown).

[0089] from Figure 4 and Figure 5 It can be clearly seen that the indicator 110 of the contact indication mechanism is exposed to the user's sight through the hollow portion or transparent window 166 on the decorative cover 160 for the user to observe.

[0090] Now refer to Figures 6 to 8 The specific structure of the contact indication mechanism according to the present application and how it is installed on the supporting foot 100 are described in detail.

[0091] 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 also include a mounting member 120, a first elastic member 182, a first screw 181 ( Fig. 9A , Fig. 9B ), the second elastic member 183, and the second screw 184.

[0092] The indicator 110 is disposed at the indicating end of the support foot 100 via a transverse 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 a state where the support foot is not in contact with the ground, and the second position corresponds to a state where the support foot is in contact with the ground. In one embodiment, a first area 111 and a second area 112 are circumferentially arranged on the cylindrical outer periphery of the indicator 110 (see Fig. 9A , Fig. 9B ). When the support leg 100 is in its non-contacting position, the first area 111 is exposed from the hollow portion or the transparent window 166; when the support leg 100 is in its contacting position, the second area 112 is exposed from 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 drawn with different marks (such as dots, oblique lines or other patterns), as long as they can be used to indicate whether the support leg 100 is touching the ground, the embodiments of the present application do not limit the expression of the first area and the second area. The shapes of the first area 111 and the second area 112 may correspond to the shapes of the hollow portion or the transparent window 166.

[0093] The movable shaft 114 can be directly mounted on the indicating end of the support foot 100, or can be mounted to the indicating end through the mounting member 120. For example, the movable shaft 114 is mounted 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 foot 100 is a hollow tubular member, and the mounting member 120 can be fixed to the inner side of the indicating end, but the present application is not limited to this.

[0094] 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 toward the first position.

[0095] The first side of the indicator 110 has a first receiving portion 113 for receiving the first end 151 of the cable, and 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 opposite to the second side.

[0096] The driving member 130 is at least partially disposed in the contact end of the supporting foot 100 and includes a contact portion 131 extending vertically 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 from the contact end and a retracted position where the contact portion 131 retracts into the contact end.

[0097] More specifically, the driving member 130 may include a shoulder 135 and a column hole 132. The shoulder 135 is located inside the contact end of the support foot 100 and extends approximately transversely, and the two contact portions 131 extend vertically outward from the contact end from both transverse ends of the shoulder 135. The column hole 132 is provided on the shoulder 135, and can be slidably mounted on a column 141 extending inwardly from the bottom of the contact end.

[0098] In one embodiment, a second elastic member 183 is provided between the driving member 130 and the contact end of the component, and the second elastic member 183 biases the driving member 130 toward the extended position. The second elastic member 183 may be a coil spring, and 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 arrangement of the second elastic member 183 is not limited to this, as long as the driving member 130 is biased toward the extended position.

[0099] The driving member 130 further includes a cable sleeve 155 mounting portion (i.e., the second receiving portion 133), which extends vertically inward from the center of the shoulder portion 135, is in the form of a groove and has a shape corresponding to the second end 157 of the cable sleeve, and is used to fix the second end 157 of the cable sleeve. It should be understood that the form of the cable sleeve mounting portion is not limited thereto, but can be changed accordingly according to the form of the second end of the cable sleeve.

[0100] The fixing seat 140 is a substantially flat component extending in the transverse and longitudinal directions. In an embodiment in which the fixing seat 140 is provided as a separate component, the lower end (contact end) of the supporting foot 100 may be an open end, and the fixing seat 140 is used to close the open end. The column 141 and the third receiving portion 142 are provided on the inner side of the fixing seat 140. A through hole is provided on the fixing seat 140 so that the contact portion 131 of the driving member 130 extends outward from the supporting foot 100. As described above, the fixing seat 140 may be integrated into the supporting foot 100 as an integral component.

[0101] The cable sleeve 155 extends substantially vertically between the indicating end and the contact end of the support foot 100. The cable sleeve 155 includes a cable sleeve first end 156 fixed to the indicating end and a cable sleeve second end 157 fixed to the driving member 130. The cable sleeve 155 can be made of materials such as rubber or plastic, which has a certain degree of flexibility and can be bent, but its length does not change substantially.

[0102] In one embodiment, the first end 156 and the second end 157 of the cable sleeve are both in the form of hammer heads 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 ​​parts, or directly welded to the indicating end and the driving member 130.

[0103] The cable 150 extends substantially vertically between the indicating end and the contact end of the supporting foot 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, and 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, and has a certain flexibility and can be bent, but its length does not substantially change.

[0104] In one embodiment, the first cable end 151 and the second cable end 152 are both in the form of hammer heads with increased diameters at both ends. It should be understood that the first cable end 151 and the second cable end 152 may also be in other forms, such as external threads, knots, or directly welded to the indicating end and the contact end.

[0105] Now refer to 9A to 10B The operation of the contact indication mechanism of the present application is described.

[0106] As shown in the figure, Fig. 9A and Fig. 10A In the illustrated case, the indicator 110 is in its first position and the drive member 130 is in its extended position. The first area 111 of the indicator 110 faces upward (i.e., where the hollow portion or transparent window 166 on the decorative cover 160 is located) to show that the support foot 100 is not touching the ground. Due to the biasing effect of the first elastic member 182 and the second elastic member 183, the indicator 110 and the drive member 130 tend to remain in the position without the influence of external forces. Fig. 9A and Fig. 10A Position shown.

[0107] exist Fig. 9B and Fig. 10B In the case shown, the contact end has already contacted the ground. The contact portion 131 of the driving member 130 is exposed to the outside of the supporting foot 100, and therefore receives the pressure of the ground first. Thus, it overcomes the biasing force of the second elastic member 183 and moves to its retracted position. 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 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 will not move away from the contact end, i.e., will not move upward. In this way, it is equivalent to the second end 152 of the cable extending out of the second end 157 of the cable sleeve by a certain length. As mentioned above, the lengths of the cable and the cable sleeve are basically unchanged, that is, the length of the portion of the cable 150 in the cable sleeve 155 is basically unchanged. In this way, when the second end 152 of the cable extends out of the second end 157 of the cable sleeve by a certain length, the first end 151 of the cable will be retracted into the first end 156 of the cable sleeve by a corresponding length. Since the cable sleeve first end 156 is fixed to the indicating end of the support foot 100, the cable 150 slides relative to the cable sleeve 155 toward the contact end, thereby driving the indicator 110 to rotate from its first position to the second position.

[0108] In other embodiments, the indicator 110 can be configured to move linearly rather than rotate. For example, the indicator 110 is disposed in the indicating end portion via a slide rail and is capable of sliding between a second position and a first position. In the absence of an external force, the indicator 110 is biased toward the first position. When the contact end portion contacts the surface, the cable 150 (specifically, the first end 151 of the cable) drives the indicator 110 to overcome the biasing force and move to the second position. The slide rail can be disposed horizontally, and the vertical movement of the cable 150 is converted into a horizontal movement by a pulley at the indicating end portion. The slide rail can also be disposed vertically, and the hollow portion or transparent window 166 is opened on the vertical surface of the decorative cover 160.

[0109] FIG. 11A to FIG. 11B provide an explanation of the technical principle of the present application. When the cable sleeve 155 changes from the non-contact state shown in FIG. 11A to the contact state shown in FIG. 11B, the second end 157 of the cable sleeve is pushed upward, but the first end 156 of the cable sleeve is fixed, so the cable sleeve 155 is bent (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 curved path of the cable sleeve 155, so the extension path of the cable 150 from the indicating end to the contact end is actually longer. Since the second end 152 of the cable is fixed at the contact end, the first end 151 of the cable is forced to shrink inward.

[0110] Although FIG. 11A shows that the cable sleeve 155 and the cable 150 extend substantially in a straight line, it should be understood that in the non-contact state, the cable sleeve 155 and the cable 150 may not necessarily extend in a straight line. In fact, the cable sleeve 155 and the cable 150 may also be curved in the non-contact state, and become more curved in the contact state, and their functions can also be achieved. The advantage of this characteristic is that the cable 150 and the cable sleeve 155 can adapt to various lengths of the support leg 100. For example, the length of the cable 150 and the cable sleeve 155 can be designed to correspond to the maximum length of the support leg 100. When the support leg 100 is adjusted to be shortened, the cable 150 and the cable sleeve 155 are connected between the two ends of the support leg 100 in a curved manner, and the function of indicating contact can still be achieved.

[0111] In summary, the present application provides a contact indication mechanism that can intuitively display whether one end of a support leg is in contact with 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 can also achieve its contact indication function. 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.

[0112] The present application also provides a support foot, which has a contact indication mechanism and an extension indication mechanism, which can prompt the user of the extension state and the ground contact state of the support foot.

[0113] The present application also provides a vehicle having a support leg according to the present application, and the support leg can be folded and retracted under the base of the vehicle.

[0114] Although preferred embodiments have been shown and described herein, it should be understood that these embodiments are provided as examples only. Those skilled in the art will appreciate that many modifications, changes and substitutions will not deviate from the spirit of the present invention. Therefore, the appended claims are intended to cover all such modifications that fall within the spirit and scope of the present invention.
