Description

Connecting device of vehicle seat and vehicle

Technical Field

The disclosure relates to the technical field of vehicles, in particular to a connecting device of a saddle and a vehicle.

Background

The saddle of a bicycle or electric bicycle is often connected to the seat post by a clamp ring. Vehicle seats typically include a seat bottom and a seat bow for supporting the seat bottom. The seat bow is provided with a fixing ring to fix the seat bow and the seat rod together.

With the increase of the number of times of use of the vehicle, the seat can rotate left and right relative to the seat post, and the front end of the seat can also generate serious up and down displacement along the axial direction of the seat post, such as the situation that the seat tilts up.

In particular, in the field of shared bicycles, the seat is adjusted repeatedly many times due to the high frequency of use of the shared bicycle. This more easily causes unstable fixation of the seat and the seat post, and the seat rotates left and right. When users with different weights use the sharing bicycle, the saddle can also generate obvious tilting up and down due to different stresses.

The saddle includes a saddle body and a support structure 40, the support structure 40 being connected to the saddle body and being configured to provide support for the saddle body. The supporting structure 40 has a first supporting arm 41 and a second supporting arm 42, and the first supporting arm 41 and the second supporting arm 42 are connected at the same end to form a v-shaped structure.

It will be appreciated that the shape of the support structure 40 may also be of a race track type, U-shaped or the like to provide support for the body of the vehicle seat, as will be appreciated by those skilled in the art.

According to an embodiment of the present disclosure, there is provided a connecting device of a vehicle seat. As shown in fig. 1 to 3, the connecting device includes a fixing assembly 10, a connecting rod 20, and a seat post 30. The fixing assembly 10 comprises a first fixing element 11. The first fixing member 11 and the seatpost 30 form an installation space 113 therebetween.

As shown in fig. 6, a first through hole 111 is provided in the first fixing member 11, and a second through hole penetrating the seatpost 30 is provided in a radial direction of the seatpost 30.

At least part of the connecting rod 20 is located in the first through hole 111 and the second through hole, the connecting rod 20 forms a rotation-stop fit with the seat post 30, and the connecting rod 20 forms a rotation-stop fit with the first fixing element 11.

The fixing assembly 10 fixes the first support arm 41 and/or the second support arm 42 for the vehicle seat to the seatpost 30.

For example, as shown in fig. 1, the fixing assembly 10 includes a first fixing element 11. The side wall of the first fixing element 11 facing the seat post 30 forms a relief, which encloses an installation space 113 with the side wall of the seat post 30.

Specifically, the size of the mounting space 113 matches the size of the first support arm 41 and/or the second support arm 42. The installation space 113 is configured to enable the first support arm 41 and/or the second support arm 42 to be embedded therein. Meanwhile, the sidewall of the escape portion of the first fixing element 11 forms a limiting surface to prevent the first support arm 41 or the second support arm 42 located in the installation space 113 from sliding out of the installation space 113.

For example, as shown in fig. 1, the first support arm 41 of the seat is fitted into the fitting space 113. A part of one side of the first support arm 41 of the seat is in contact with the first fixing member 11, and the first support arm 41 is pressed against the outer wall of the seat post 30 by the first fixing member 11.

A first through-hole 111 is formed on the first fixing member 11. The first through hole 111 has a triangular, square, trapezoidal, etc. cross-section.

A second through-hole is formed in the seatpost 30.

For example, the seat post 30 is a solid structure. A second through hole penetrating the sidewall of the seatpost 30 is formed in a radial direction of the seatpost 30. The second through hole forms two openings in the side wall of the seatpost 30.

Alternatively, for example, as shown in fig. 1-3, the seatpost 30 is a hollow structure. A second through hole penetrating the sidewall of the seatpost 30 is formed in a radial direction of the seatpost 30. The number of the second through holes is two, and the two second through holes are oppositely arranged.

The first through-hole 111 is matched with the second through-hole. In the present embodiment, the matching of the first through hole 111 and the second through hole means that the size of the first through hole 111 and the size of the second through hole can be matched with the shape and size of the connecting rod 20 to form a rotation-stop fit, respectively. Meanwhile, the first through hole 111 and the second through hole have such dimensions that a part of the connection rod 20 can pass through the first through hole 111 and enter the second through hole.

The shape of the second through hole may be the same as that of the first through hole 111, and may be a triangle, a square, a trapezoid, or the like; the shape of the second through hole may be different from the shape of the first through hole 111. For example, the first through hole 111 has a square shape, and the second through hole has a diamond shape.

The connecting rod 20 is located in the first through hole 111 and the second through hole and forms a rotation stop fit with the seat post 30 and the first fixing element 11 respectively to prevent the connecting rod 20 from rotating in the first through hole 111 along the circumferential direction of the first through hole 111 so as to drive the front end of the seat to move up and down along the axial direction of the seat post 30. At the same time, the rotation of the seat in the circumferential direction of the seat post is also avoided.

Specifically, as shown in fig. 5, the connecting rod 20 includes a limiting portion 21, and a cross section of a portion of the limiting portion 21 located in the first through hole 111 matches a shape of the first through hole 111. The cross section of the part of the limiting part 21 in the second through hole is matched with the shape of the second through hole.

For example, when the shape of the first through hole 111 is square, the section of the portion of the connection rod 20 located inside the first through hole 111 is square. The shape of the second through hole is the same as the shape of the first through hole 111, and the cross section of the portion of the connection rod 20 located in the second through hole is square.

Alternatively, when the first through hole 111 is square and the second through hole is diamond-shaped, the portion of the limiting portion 21 located in the first through hole 111 is square, and the portion of the connecting rod 20 located in the second through hole is diamond-shaped.

In this way, the connecting rod 20 is prevented from rotating in the first through hole 111, and the connecting rod 20 is also prevented from rotating in the second through hole, so that the rotation-stopping engagement of the connecting rod 20 with the first fixing member 11 and the rotation-stopping engagement with the seatpost 30 are achieved.

For example, as shown in fig. 1, 4 and 6, an installation space 113 is formed between the first fixing member 11 and the seatpost 30. A second through hole penetrating the seat post 30 is formed in the radial direction of the seat post 30 by partially fitting the seat into the fitting space 113. A first through hole 111 is provided on the first fixing element 11. The connecting rod 20 is passed through the first and second through holes 111 and into a detent fit with the seatpost 30. At the same time, the connecting rod 20 also forms a detent fit with the first fixing element 11 to fix the seat on the seat post 30.

Thus, the seat is effectively prevented from being inclined upward and downward with respect to the axial direction of the seat post 30.

In one example of the present disclosure, the fixing assembly 10 includes two first fixing elements 11, the two first fixing elements 11 are symmetrically disposed with respect to the seatpost 30, and first through holes 111 are provided on both the two first fixing elements 11.

For example, as shown in fig. 1-4, two first fixing elements 11 commonly clamp the seatpost 30. The two first fixing elements 11 are each formed with a first through hole 111, and the two first through holes 111 correspond in position, i.e., the two first through holes 111 can be penetrated by the connecting rod 20. The positions of the two first through holes 111 correspond to the positions of the second through holes. The two first and second through holes 111, 111 are configured to enable the connecting rod 20 to pass through and form a detent fit with the two first through holes 111, while forming a detent fit with the second through hole.

Specifically, when the vehicle seat is attached, the first support arm 41 is fitted into the mounting space 113 defined by the first fixing member 11 on one side, and the second support arm 42 is fitted into the mounting space 113 defined by the first fixing member 11 on the other side.

The two first fixing members 11 are pressure-fitted to the side wall of the seatpost 30 so that the two first fixing members 11 hold the side wall of the seatpost 30.

The connecting rod 20 enters from the first through hole 111 of the first fixing element 11 on one side of the fixing assembly 10, passes through the second through hole, and then extends out from the second through hole of the first fixing element 11 on the other side. The connecting rod 20 is respectively matched with the two first through holes 111 and the second through holes in a rotation stopping manner.

For example, as shown in fig. 1, when the seat is brought into a coupled state with the seat post 30, the mounting space 113 is located at an upper portion of the connecting rod 20, i.e., the height of the mounting space 113 in the axial direction of the seat post 30 is greater than the height of the connecting rod 20 in the axial direction of the seat post 30. In this state, the first support arm 41 and the second support arm 42 are located at the upper portion of the connection rod 20.

In this way, when the connecting rod 20 is in anti-rotation engagement with the first fixing element 11 and the seatpost 30, it is ensured that the first fixing element 11 does not shift relative to the seatpost 30. So that the first support arm 41 and the second support arm 42 fitted into the two fitting spaces 113, respectively, are not offset with respect to the seatpost 30. This effectively prevents the seat from tilting up and down relative to the axial direction of the seat post 30 and also prevents the seat from rotating in the circumferential direction of the seat post.

Alternatively, when the seat is brought into a coupled state with the seat post 30, the mounting space 113 is located at a lower portion of the connecting rod 20, i.e., the height of the mounting space 113 in the axial direction of the seat post 30 is smaller than the height of the connecting rod 20 in the axial direction of the seat post 30.

Alternatively, when the height of the installation space 113 in the axial direction of the seat post 30 is smaller than the height of the connecting rod 20 in the axial direction of the seat post 30, the first support arm 41 abuts against the bottom surface of the connecting rod 20, and the second support arm 42 abuts against the bottom surface of the connecting rod 20. Thus, the connecting rod 20 has a limiting function on the first supporting arm 41 and the second supporting arm 42, and the connecting strength between the saddle and the seat post 30 is increased.

In addition, the tilting of the end of the seat up and down relative to the seat post 30 is further avoided.

In addition, the load bearing capacity of the seat and seat post 30 is increased.

For example, as shown in fig. 5, the connecting rod 20 includes a limiting portion 21 and two connecting portions 22 disposed opposite to each other. One end of the stopper portion 21 is connected to one of the connecting portions 22, and the other end of the stopper portion 21 is connected to the other connecting portion 22.

For example, as shown in fig. 1 to 4, in a state where the seat is connected to the seat post 30, the stopper portion 21 is located in the first through hole 111 and the second through hole. The connecting portions 22 protrude from both ends of the fixing member 10.

In one example, as shown in fig. 5, the stopper portion 21 has a square cross section, and the connecting portion 22 has a circular cross section. Thus, the connecting rod 20 can be processed in a simpler manner.

In one example, as shown in fig. 5, the projected area of at least one connecting portion 22 is smaller than the projected area of the stopper portion 21.

For example, the connecting portion 22 is circular, and the boundary of the projection of the connecting portion 22 is tangent to the boundary of the projection of the stopper portion 21. The boundary is the side of the orthographic projection surface of the connecting portion 22 and the side of the orthographic projection surface of the stopper portion 21.

Thus, the coupling strength of the connecting rod 20 to the fixing assembly 10 and the connecting rod 20 to the seat post 30 is further enhanced.

In one example of the present disclosure, as shown in fig. 1 to 4, the connecting rod 20 has connecting portions 22 at both ends thereof, and a fastening member 50 is disposed to match at least one of the connecting portions 22, and the connecting portion 22 extends from the first fixing member 11 and is detachably connected to the fastening member 50.

For example, the fastener 50 is used to form a connection with the connecting portion 22 to secure the fixing assembly 10 to the seatpost 30 to increase the connection strength of the connecting member. The fastening member 50 is screwed or riveted with the connecting portion 22, and is not limited in particular, so as to enhance the connecting strength of the connecting member.

For example, the cross section of the connection portion 22 is circular, and a male screw is formed on the outer wall of the connection portion 22 in the circumferential direction of the connection portion 22. The fastener 50 is a nut having internal threads. After the connecting piece passes through the first through hole 111 and the second through hole, the limiting part 21 of the connecting piece is positioned in the first through hole 111 and the second through hole. The connecting portion 22 protrudes outside the fixing member 10. The fastener 50 is threadedly engaged with the coupling portion 22.

Thus, the coupling strength of the fixing assembly 10 to the seatpost 30 is further increased.

In one example of the present disclosure, as shown in fig. 1-4 and 6, the fixation assembly 10 further includes a second fixation element 12. The second fixing element 12 is fitted over the seat post 30. A third through-hole 121 is provided in the second fixing element 12. The third through hole 121 is matched with the second through hole, and parts of the connecting rod 20 are located in the first through hole 111, the second through hole and the third through hole 121.

For example, the second fixing element 12 is ring-shaped. The second fixing element 12 is fitted over the end of the seatpost 30. The two first fixing elements 11 are respectively pressed against the outer wall of the second fixing element 12. The connecting rod 20 enters from the first through hole 111 at one side of the seat post 30, passes through the third through hole 121 and the second through hole, and then extends out of the fixing assembly 10 from the first through hole 111 at the other side of the seat post 30. The position-limiting part 21 is located in the first through hole 111, the second through hole and the third through hole 121 to form a position-limiting fit with the fixing assembly 10, i.e. the first fixing element 11 and the second fixing element 12. At the same time, form a detent fit with seatpost 30.

In this way, the effect of the detent fitting is further enhanced.

In one example of the present disclosure, a groove 122 is formed in an outer wall of the second fixing element 12, and the first fixing element 11 and the groove 122 together enclose the installation space 113.

For example, as shown in fig. 3, the second fixing element 12 is fitted over one end of the seat post 30, and a groove 122 matching the relief of the first fixing element 11 is formed in the outer wall of the second fixing element 12 to form a mounting space 113.

Thus, when the seat is connected with the frame, the contact area of the installation space 113 and the seat post supporting structure 40 is increased, and the connection strength of the connecting device and the seat is further enhanced.

In one example of the present disclosure, a recess 32 is formed in an outer wall of the seat post 30, the recess 32 extending in an axial direction of the seat post 30, and the second fixing member 12 is configured with a notch, the recess 32 facing the notch.

For example, as shown in fig. 1, 2, and 4, a notch is formed along the circumferential direction of the second fixing element 12, and the notch penetrates the side surface of the second fixing element 12 along the circumferential direction. The recess 32 faces the notch.

When attaching the seat to the frame, seat post 30 is inserted into the frame so that recess 32 forms a positive fit with a portion of the frame, while allowing seat post 30 to move in the bracket to adjust the height of the seat. The second fixing element 12 is sleeved on the end of the seat post 30, the concave portion 32 faces to the gap, and the gap avoids the concave portion 32, so that the connection between the frame and the seat post 30 is more convenient.

Further, by forming the notch on the second fixing member 12, the elasticity of the second fixing member 12 can be increased, and the clamping force of the second fixing member 12 and the seatpost 30 is increased when the second fixing member 12 is coupled with the seatpost 30.

In addition, the recessed portion 32 forms a positive fit with a portion of the frame to prevent circumferential rotation of the seatpost 300 relative to the frame.

In one example of the present disclosure, as shown in fig. 6, the second fixing member 12 includes a top wall 123, a first side wall 124, and a second side wall 125, the first side wall 124 is disposed opposite to the second side wall 125, the first side wall 124 and the second side wall 125 are both connected to the top wall 123, and the third through hole 121 is disposed on both the first side wall 124 and the second side wall 125.

For example, the top wall 123 is configured to abut against a side surface of the seatpost 30, a top end of the first side wall 124 is connected to one side of the top wall 123, and a top end of the second side wall 125 is connected to the other side of the top wall 123. For example, the metal plate is bent to form the metal plate after welding or integral forming.

The first side wall 124 and the second side wall 125 are disposed radially of the seat post 30 and symmetrically with respect to the seat post 30.

Thus, the structure of the fixing component is simplified, and the saddle and the frame can be conveniently connected.

In one example, as shown in fig. 6, the first fixing member 11 includes a first blocking wall 114 and a second blocking wall 115. The first blocking wall 114 and the second blocking wall 115 are symmetrically arranged with respect to the second fixing element 12. The first blocking wall 114 is connected to an end of the first side wall 124 away from the top wall 123. The second blocking wall 115 is connected to an end of the second side wall 125 away from the top wall 123. The first blocking wall 114 and the second blocking wall 115 are each configured with a first through hole 111.

For example, the first fixing element 11 is located outside the second fixing element 12 and is connected to the second fixing element 12. The first blocking wall 114 is connected to an end of the first side wall 124 away from the top wall 123, and the second blocking wall 115 is connected to an end of the second side wall 125 away from the top wall 123. The first through-hole 111 is formed in each of the first blocking wall 114 and the second blocking wall 115.

Specifically, the first through hole 111 matches with the third through hole 121 on the first sidewall 124 and the second sidewall 125. Meanwhile, the first through hole 111 is matched with the second through hole. The first through hole 111 is matched with the second through hole and the third through hole 121, which means that the sizes of the first through hole 111, the second through hole and the third through hole 121 are matched with the shape and the size of the connecting rod 20 to form rotation-stopping fit. Meanwhile, the first through hole 111, the second through hole and the third through hole 121 have such dimensions that a part of the connection rod 20 can pass through the first through hole 111, the second through hole and the third through hole 121.

For example, as shown in fig. 6, a third sidewall 126 is connected between the first sidewall 124 and the second sidewall 125, and the third sidewall 126 is simultaneously connected to the top wall 123. This increases the structural support of the second fixing element 12.

For example, the first sidewall 124 is welded to the first blocking wall 114, and the second sidewall 125 is welded to the second blocking wall 115.

Optionally, the middle portion of the first side wall 124 is bent by sheet metal working to form the bent portion 127 and the first blocking wall 114, and the top end of the first blocking wall 114 is close to the top wall 123. The first blocking wall 114 is spaced apart from the first sidewall 124.

The middle portion of the second side wall 125 is bent by sheet metal working to form a bent portion 127 and a second blocking wall 115, and the top end of the second blocking wall 115 is close to the top wall 123. The second blocking wall 115 is spaced apart from the second sidewall 125.

In one example, as shown in fig. 6, the installation space 113 is located at a side of the third through hole 121 facing away from the top wall 123.

When the seat is connected to the seat post 30, the first support arm 41 is inserted into the installation space 113 between the first blocking wall 114 and the first side wall 124 and contacts the bent portion 127. The second support arm 42 is inserted into the installation space 113 between the second blocking wall 115 and the second side wall 125 and contacts the bent portion 127. The third through hole 121 is located outside the first and second support arms 41 and 42 to form a stopper for the first and second support arms 41 and 42. After the connection rod 20 is inserted into the first through hole 111, the second through hole, and the third through hole 121, the connection rod 20 and the bent portion 127 fix the first support arm 41 and the second support arm 42 in the installation space 113, respectively.

In one example, as shown in FIG. 6, the securing assembly 10 is a unitary structure.

For example, the fixing assembly 10 includes a first fixing element 11 and a second fixing element 12. The first fixing element 11 and the second fixing element 12 are connected by means of sheet metal working to form an integral structure.

For example, as shown in fig. 6, the fixing assembly 10 includes a body portion. The body portion has a top wall 123, a first side wall 124 and a second side wall 125. The first side wall 124 is disposed opposite the second side wall 125. The first side wall 124 and the second side wall 125 form a receiving space therebetween to receive the seatpost 30. An escape hole is formed in the top wall 123, and the seat post 30 is inserted through the escape hole.
