Description

Technical Field

[0001] The invention relates to a car safety seat base, in particular to a car safety seat base which drives an indicator to rotate by rotating a supporting foot. Background Art

[0002] At present, some car safety seat bases are provided with support feet. When the car safety seat base is set on the car seat, the support feet can be against the floor of the car. Therefore, when the car is hit, the support feet can support the car safety seat base to prevent the car safety seat base from tipping forward or overturning. Generally speaking, an indicator structure is provided on the support foot to indicate whether the support foot is fully unfolded. Common indicator structures are set at the bottom of the support foot. This indicator structure is located low and is not convenient for users to observe. Some indicator structures are set at the top of the support foot. This indicator structure is mostly driven by the overall movement of the support foot or the relative movement of the upper and lower pipes of the support foot. Therefore, there will be relative shaking between the support foot and the car safety seat base or the two pipes of the support foot, thereby generating noise. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to make up for the deficiencies of the prior art, a car safety seat base is provided which drives the indicator to rotate by the rotation of the supporting legs, so as to solve the above problems.

[0004] The car safety seat base of the present invention adopts the following technical solutions:

[0005] The car safety seat base includes a base body, an indicator and a support leg. The base body includes a bracket, and the bracket has an indicator window. The indicator is rotatably connected to the bracket, and the indicator has a first color block. The support leg is rotatably connected to the bracket, and the support leg has a protrusion. When the support leg rotates to an unfolded position, the protrusion pushes the indicator to rotate upward, so that the indicator window displays the first color block.

[0006] Preferably, when the supporting leg rotates away from the unfolded position, the indicator rotates downward, so that the first color block disappears from the indicator window.

[0007] Preferably, the indicator also has a second color block, and the first color block is different from the second color block. When the support leg rotates away from the unfolded position, the indicator rotates downward, so that the indicator window displays the second color block.

[0008] Preferably, when the supporting legs are not fully unfolded, the indicator window displays part of the first color block and part of the second color block.

[0009] Preferably, the supporting foot comprises a decorative cover, and the protrusion protrudes from a side of the decorative cover.

[0010] Preferably, the car safety seat base further comprises a torsion spring, two ends of which are respectively in contact with the support leg and the bracket, and the torsion spring biases the support leg toward the unfolded position.

[0011] Preferably, the car safety seat base further comprises an elastic sheet, which is arranged on the bracket and limits the support legs from rotating toward the unfolded position.

[0012] Preferably, the car safety seat base also includes a warning device, which is arranged on the base body. When the support legs are not fully extended, the warning device sends a warning message. When the support legs are fully extended, the spring triggers the warning device to stop sending the warning message.

[0013] Preferably, the bracket has a first limiting portion, the indicator has a second limiting portion, and the first limiting portion cooperates with the second limiting portion to limit the indicator from rotating downward.

[0014] Preferably, the car safety seat base further comprises a warning device, which is arranged on the base body. When the support legs are not fully extended, the warning device sends a warning message. When the support legs are fully extended, the warning device stops sending the warning message.

[0015] Preferably, when the supporting legs are fully extended, the indicator triggers the warning device to stop issuing warning information.

[0016] Preferably, the support leg includes a first support member, a second support member, a fixed seat and a locking member. The first support member is rotatably connected to the bracket. The second support member is telescopically connected to the first support member, and the second support member has a plurality of engaging holes. The fixed seat is disposed on the first support member. The locking member is rotatably connected to the fixed seat, and the locking member has a locking portion and an operating portion, and the locking portion is engaged with one of the plurality of engaging holes to lock the first support member and the second support member. When the operating portion is pressed, the locking portion disengages from the engaging hole, so that the second support member can move relative to the first support member.

[0017] Preferably, the supporting foot further includes a torsion spring, which is disposed in the fixing seat, and two ends of the torsion spring are respectively in contact with the first supporting member and the fixing seat.

[0018] Therefore, according to the above technical scheme, the car safety seat base of the present invention has at least the following advantages and beneficial effects: the present invention sets the indicator window on the bracket of the base body, and the indicator window is located at the top of the support leg, which is convenient for users to observe. The present invention can drive the indicator to rotate by rotating the support leg, so the support leg will not shake and will not generate noise. In addition, the present invention can send out a warning message through the warning device to indicate whether the support leg is fully unfolded, so the user can also know whether the support leg is fully unfolded through the warning device. If the support leg is fully unfolded before it is against the floor of the car, the user will mistakenly think that the car safety seat base has been correctly assembled to the car seat, thereby causing danger. Therefore, the present invention can use the spring sheet to limit the support leg from rotating toward the unfolded position. Only when the support leg is against the floor of the car can the support leg overcome the elastic force of the spring sheet and rotate to the unfolded position. In this way, it can be avoided that the support leg is fully unfolded before it is against the floor of the car, so as to ensure that the car safety seat base is assembled correctly.

[0055] Please refer to Figures 1 to 5 , Figure 1 1 is a side view of a car safety seat base 1 according to an embodiment of the present invention. Figure 2 yes Figure 1 A side view of the support foot 14 in FIG. 1 with the support foot 14 rotated away from the deployed position, Figure 3 yes Figure 1 A side view showing the relative positions of the support foot 14 and the indicator 12, Figure 4 yes Figure 2 A side view showing the relative positions of the support foot 14 and the indicator 12, Figure 5 It is a three-dimensional view of the bracket 100 and the indicator 12 .

[0056] like Figures 1 to 4 As shown in FIG. 1 , the car safety seat base 1 of the present invention comprises a base body 10, an indicator 12 and a support leg 14. The base body 10 of the car safety seat base 1 can be set on the car seat. The user can rotate the support leg 14 to Figure 1 In the deployed position shown, the support legs 14 are against the floor of the car. Therefore, when the car is hit, the support legs 14 can support the car safety seat base 1 to prevent the car safety seat base 1 from tipping forward or overturning. When the car safety seat base 1 is removed from the car seat, the user can rotate the support legs 14 away from the deployed position (such as Figure 2 ), to fold the supporting legs 14.

[0057] like Figure 1 and Figure 2 As shown, the base body 10 includes a bracket 100, and the bracket 100 has an indication window 102. Figure 3 and Figure 4 As shown, the indicator 12 is rotatably connected to the bracket 100. In this embodiment, the indicator 12 can be rotatably connected to the bracket 100 via a pivot 120. The indicator 12 has a first color block 122 and a second color block 124, wherein the first color block 122 is different from the second color block 124. In practical applications, the first color block 122 can be green, and the second color block 124 can be red, but not limited to this. The first color block 122 and the second color block 124 can be set to other different colors according to practical applications. In addition, as Figure 5 As shown, the present invention can set two indicator members 12 on two sides of the bracket 100. The indicator window 102 of the bracket 100 is used to display the color block of the indicator member 12. Therefore, when there are two indicator members 12 set on two sides of the bracket 100, the two sides of the bracket 100 will have two corresponding indicator windows 102. Of course, the present invention can also set a single indicator member 12 on one side of the bracket 100. In this case, one side of the bracket 100 will have a corresponding single indicator window 102.

[0058] like Figure 3 and Figure 4 As shown, the support leg 14 is rotatably connected to the bracket 100. In this embodiment, the support leg 14 can be rotatably connected to the bracket 100 via a pivot 140. The support leg 14 has a protrusion 142. In this embodiment, the support leg 14 can include a decorative cover 144, and the protrusion 142 can protrude from the side of the decorative cover 144. The protrusion 142 of the support leg 14 is used to push the indicator 12 to rotate. Therefore, when two indicator members 12 are disposed on two sides of the bracket 100, the two sides of the support leg 14 will have two corresponding protrusions 142.

[0059] like Figure 1 and Figure 3 As shown in FIG. 1 , when the support leg 14 rotates to the unfolded position, the protrusion 142 of the support leg 14 pushes the indicator 12 to rotate upward. At this time, the first color block 122 of the indicator 12 is aligned with the indicator window 102, so that the indicator window 102 displays the first color block 122. Figure 2 and Figure 4 As shown, when the support leg 14 rotates away from the unfolded position, the indicator 12 will rotate downward due to its own weight. At this time, the second color block 124 of the indicator 12 will align with the indicator window 102, so that the indicator window 102 displays the second color block 124. Therefore, when the user sees that the indicator window 102 displays the first color block 122, it means that the support leg 14 has rotated to the unfolded position. On the contrary, when the user sees that the indicator window 102 displays the second color block 124, it means that the support leg 14 has not yet rotated to the unfolded position. It should be noted that when the support leg 14 is close to the unfolded position but not fully unfolded, the indicator window 102 will display part of the first color block 122 and part of the second color block 124. At this time, it means that the support leg 14 has not yet rotated to the unfolded position, that is, the support leg 14 has not yet rested against the floor of the car.

[0060] like Figure 5 As shown, the bracket 100 may have a first limiting portion 104, and the indicator 12 may have a second limiting portion 126. The first limiting portion 104 cooperates with the second limiting portion 126 to limit the indicator 12 from rotating downward. Therefore, when the support leg 14 rotates away from the unfolded position (for example, rotates to the folded position), the indicator 12 will rotate downward to the position due to its own weight. Figure 5 At this time, the first limit portion 104 will stop the second limit portion 126 to limit the indicator 12 from continuing to rotate downward. Figure 5 When the indicator 12 is in the position shown, the second color block 124 of the indicator 12 will be aligned with the indicator window 102, so that the indicator window 102 displays the second color block 124 (such as Figure 2 shown).

[0061] Please refer to Figure 6 as well as Figure 7 , Figure 6 is a side view of the relative positions of the support foot 14 and the indicator 12 according to another embodiment of the present invention, Figure 7 yes Figure 6 Another side view of the relative position of the support foot 14 and the indicator 12 in FIG.

[0062] like Figure 6 and Figure 7 As shown, the indicator 12 may only have the first color block 122, but not the second color block 124. Figure 6 As shown in FIG. 1 , when the support leg 14 rotates to the unfolded position, the protrusion 142 of the support leg 14 pushes the indicator 12 to rotate upward. At this time, the first color block 122 of the indicator 12 is aligned with the indicator window 102, so that the indicator window 102 displays the first color block 122. Figure 7 As shown, when the support leg 14 rotates away from the unfolded position, the indicator 12 will rotate downward due to its own weight, so that the first color block 122 disappears from the indicator window 102. Therefore, when the user sees the indicator window 102 displaying the first color block 122, it means that the support leg 14 has rotated to the unfolded position. On the contrary, when the user sees that the indicator window 102 does not display the first color block 122, it means that the support leg 14 has not rotated to the unfolded position.

[0063] Please refer to Figure 8 as well as Fig. 9 , Figure 8 yes Figure 1 A partial bottom view of the car safety seat base 1 in FIG. Fig. 9 yes Figure 1 A partial cross-sectional view of a car safety seat base 1 in FIG.

[0064] like Figure 8 and Fig. 9 As shown, the car safety seat base 1 may further include a torsion spring 16. In this embodiment, the torsion spring 16 may be disposed on the pivot 140, and the two ends of the torsion spring 16 are respectively in contact with the support leg 14 and the bracket 100. The torsion spring 16 can move the support leg 14 toward the Figure 1 The bias of the deployed position shown makes it easier for the user to rotate the support leg 14 to the deployed position. It should be noted that if the support leg 14 is fully deployed due to the bias of the torsion spring 16 before it rests against the floor of the car, the indicator window 102 will display the first color block 122. At this time, the user may mistakenly believe that the car safety seat base 1 has been correctly assembled to the car seat, which may cause danger. To avoid the above situation, the car safety seat base 1 may also include a spring 18. The spring 18 is disposed on the bracket 100. When the support leg 14 is biased to the deployed position by the torsion spring 16, the indicator window 102 will display the first color block 122. Fig. 9When the support leg 14 is in the position shown, the upper end of the support leg 14 will contact the spring sheet 18. At this time, the spring sheet 18 will limit the support leg 14 from further rotating toward the unfolded position. Only when the support leg 14 is pressed against the floor of the car, the support leg 14 will overcome the elastic force of the spring sheet 18 and rotate to the unfolded position. In this way, the support leg 14 can be prevented from being fully unfolded before it is pressed against the floor of the car, so as to ensure that the car safety seat base 1 is assembled correctly.

[0065] Please refer to Fig.10 as well as Fig.11 , Fig.10 yes Figure 1 A three-dimensional view of a car safety seat base 1 in FIG. Fig.11 yes Fig.10 A cross-sectional view of the support foot 14 in FIG.

[0066] like Fig.10 and Fig.11 As shown, the support leg 14 may include a first support member 146, a second support member 148, a fixing seat 150, a locking member 152 and a torsion spring 154. The first support member 146 is rotatably connected to the bracket 100. The second support member 148 is telescopically connected to the first support member 146. The fixing seat 150 is disposed on the first support member 146. The locking member 152 is rotatably connected to the fixing seat 150. In this embodiment, the locking member 152 is rotatably connected to the fixing seat 150 via a pivot 156. The torsion spring 154 is disposed in the fixing seat 150. In this embodiment, the torsion spring 154 may be disposed on the pivot 156, and two ends of the torsion spring 154 are respectively abutted against the first support member 146 and the locking member 152.

[0067] like Fig.10 and Fig.11 As shown, the second support member 148 has a plurality of engaging holes 158, and the locking member 152 has an engaging portion 160 and an operating portion 162. The engaging portion 160 of the locking member 152 can be engaged with one of the plurality of engaging holes 158 to lock the first support member 146 and the second support member 148. When the user wants to adjust the length of the support leg 14, the user can press the operating portion 162 of the locking member 152. When the operating portion 162 of the locking member 152 is pressed, the engaging portion 160 will be disengaged from the engaging hole 158, so that the second support member 148 can move relative to the first support member 146, thereby adjusting the length of the support leg 14. When the length of the support leg 14 is adjusted, the user can release the operating portion 162 of the locking member 152. At this time, the torsion spring 154 drives the locking member 152 to return to its original position, so that the engaging portion 160 of the locking member 152 engages with the corresponding engaging hole 158 again to lock the first supporting member 146 and the second supporting member 148. Since the length of the supporting foot 14 is adjustable, the car safety seat base 1 of the present invention can be assembled in cars with different floor heights, which is more flexible in use.

[0068] Please refer to Fig.12 , Fig.12 It is a three-dimensional diagram of a car safety seat base 1 according to another embodiment of the present invention.

[0069] like Fig.12 As shown, the car safety seat base 1 may further include a warning device 20. The warning device 20 is disposed on the base body 10. When the support leg 14 is not fully extended, the warning device 20 may issue a warning message to remind the user. Conversely, when the support leg 14 is fully extended, the warning device 20 will stop issuing the warning message. Therefore, the user can know whether the support leg 14 is fully extended through the warning device 20. In one embodiment, the car safety seat base 1 may be provided with the above-mentioned spring sheet 18. Therefore, when the support leg 14 is fully extended, the support leg 14 will push the spring sheet 18 upward. At this time, the spring sheet 18 can contact the circuit of the warning device 20, so that the spring sheet 18 triggers the warning device 20 to stop issuing the warning message. In another embodiment, when the support leg 14 is fully extended, the support leg 14 will push the above-mentioned indicator 12 upward. At this time, the indicator 12 can contact the circuit of the warning device 20, so that the indicator 12 can trigger the warning device 20 to stop issuing the warning message. Therefore, the present invention can trigger the warning device 20 to stop issuing warning information by the spring 18 or the indicator 12, depending on the actual application. In actual applications, the warning device 20 can be a display, a light source and / or a speaker, so the warning information can be an image, text, symbol, light and / or sound.

[0070] It should be noted that the present invention can utilize the above-mentioned indicator 12 and / or warning device 20 as an indication structure to indicate whether the supporting leg 14 is fully unfolded by the rotation of the supporting leg 14. Further, in one embodiment, the present invention can utilize the above-mentioned indicator 12 as a mechanical indication structure; in another embodiment, the present invention can utilize the above-mentioned warning device 20 as an electronic indication structure; in another embodiment, the present invention can also utilize the above-mentioned indicator 12 and warning device 20 as a mechanical and electronic composite indication structure. In other words, the present invention drives the indication structure to indicate whether the supporting leg 14 is fully unfolded by the rotation of the supporting leg 14, and the above-mentioned indicator 12, warning device 20 or a combination of the indicator 12 and the warning device 20 can be selected as the indication structure according to the actual application.

[0071] Therefore, according to the above technical scheme, the car safety seat base of the present invention has at least the following advantages and beneficial effects: the present invention sets the indicator window on the bracket of the base body, and the indicator window is located at the top of the support leg, which is convenient for users to observe. The present invention can drive the indicator to rotate by rotating the support leg, so the support leg will not shake and will not generate noise. In addition, the present invention can send out a warning message through the warning device to indicate whether the support leg is fully unfolded, so the user can also know whether the support leg is fully unfolded through the warning device. If the support leg is fully unfolded before it is against the floor of the car, the user will mistakenly think that the car safety seat base has been correctly assembled to the car seat, thereby causing danger. Therefore, the present invention can use the spring sheet to limit the support leg from rotating toward the unfolded position. Only when the support leg is against the floor of the car can the support leg overcome the elastic force of the spring sheet and rotate to the unfolded position. In this way, it can be avoided that the support leg is fully unfolded before it is against the floor of the car, so as to ensure that the car safety seat base is assembled correctly.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
