Description

  The present invention relates to a vehicle component vertical support mechanism for elastically supporting a vehicle component on a vehicle body.

  A vehicle generally includes a vehicle part in which a vehicle body and a control panel attached to the vehicle body are housed. Most of the vehicle parts are preferably supported by the vehicle body so that an impact generated during traveling or loading / unloading of the luggage is not transmitted from the vehicle body to the vehicle parts. 2. Description of the Related Art Conventionally, a vehicle component support apparatus that can support a component on a main body while reducing impact from a vehicle body is known (for example, Patent Document 1). This has a vertical support mechanism for vehicle parts that elastically supports the vehicle parts in the vertical direction with respect to the vehicle body.

  This vertical support mechanism for vehicle parts includes a pair of upper and lower vehicle part side brackets provided on the vehicle part and a vehicle body side bracket provided on the vehicle body. A first spring is provided between the upper vehicle component side bracket and the vehicle body side bracket, and a first spring is provided substantially coaxially with the first spring between the vehicle body side bracket and the lower vehicle component side bracket. Has two springs. The first spring is elastically deformed by receiving a force in the compression direction due to the weight of the vehicle parts and the impact on the vehicle body while the vehicle is running. The second spring is elastically deformed by receiving a force in the compression direction due to an impact downward of the vehicle body while the vehicle is running. The elastic deformation of each spring reduces the impact from the vehicle body to the vehicle parts. Further, the second spring is usually a natural length and is elastically deformed only when the vehicle component moves upward relative to the vehicle body to reduce the upward impact. Further, since the first spring receives a force in the compression direction due to the weight of the vehicle parts, the diameter of the first spring is larger than the diameter of the second spring.

Registered Utility Model No. 3157951

  However, in the vertical support mechanism for vehicle parts having the above-described configuration, generally, the length of the spring is increased with respect to the diameter of the spring in order to increase the contraction allowance or extension allowance of the first spring or the second spring. . In such a first spring and a second spring, when an impact is applied to the vehicle and a force in the compression direction is applied to the first spring or the second spring, the deformation of the spring is not in a normal state in a straight line with respect to the compression direction. In some cases, a so-called bow-like deformation is formed in an arc shape with respect to the compression direction. As described above, when the first spring or the second spring is bowed and deformed, the impact reduction function due to the elastic deformation of the spring may not be sufficiently exhibited.

On the other hand, in order to prevent the bow deformation, a method of inserting a rod-like member inside the first spring and the second spring can be considered. Thereby, when the spring is about to be deformed like a bow, the outer peripheral portion of the rod-shaped member comes into contact with the inside of the spring, and the bow-like deformation can be prevented.
However, in order to effectively prevent the bow-shaped deformation of the spring, it is necessary to make the rod-like member have a diameter corresponding to the diameter of the spring. When the diameter of the rod-shaped member is made to correspond to the diameters of the first spring and the second spring, the rod-shaped member inevitably has a portion corresponding to the first spring and the second spring. A step portion exists in the portion corresponding to the spring. When a rod-shaped member is fixed to a vehicle body portion such as a vehicle body side bracket, the stepped portion interferes with the vehicle body side bracket or the like, and obstructs elastic deformation of the first spring having a particularly large diameter among the first spring and the second spring. . Therefore, there is a problem that the impact cannot be effectively reduced with the vehicle component vertical support mechanisms having different diameters of the first spring and the second spring as described above.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to form a bow of the first spring or the second spring in a vertical support mechanism using a first spring and a second spring having different diameters. An object of the present invention is to provide a vertical support mechanism for a vehicle component that can effectively prevent a vertical impact applied to the vehicle component by preventing deformation.

In order to solve the above problems, the present invention provides a vehicle component side bracket provided on the vehicle component for elastically supporting the vehicle component on the vehicle body, a pair of upper and lower vehicle body side brackets provided on the vehicle body, A first spring provided between the vehicle body side bracket and the vehicle component side bracket, and a second spring provided between the vehicle component side bracket and the upper vehicle body side bracket, In the vehicle component vertical support mechanism in which the diameter of the first spring is larger than the diameter of the second spring, the first spring and the second spring are supported by the vehicle component side bracket and the vehicle body side bracket. A rod-shaped guide member is inserted, and the outer diameter of the guide member has a diameter corresponding to the first spring at the portion inserted through the first spring, and the portion inserted through the second spring corresponds to the second spring. The diameter of the portion inserted through the first spring and the portion inserted through the second spring is different, and the guide member can be interlocked with the movement of the vehicle component in the vertical direction with respect to the vehicle body. It is characterized by being.

According to the present invention, the rod-shaped guide member provided so as to be interlocked with the vehicle part is inserted through the first spring and the second spring in the vertical direction with respect to the vehicle body. In the rod-shaped guide member, a portion inserted through the first spring has a diameter corresponding to the first spring, and a portion inserted through the second spring has a diameter corresponding to the second spring. Therefore, even if the first spring or the second spring is deformed like a bow when the first spring or the second spring is compressed and deformed due to the weight of the vehicle parts or due to an impact on the vehicle body while the vehicle is running, the first spring and the second spring It is guided in the normal compression direction by contact with the member. Thereby, the bow-like deformation of the first spring or the second spring can be prevented.
Here, the diameter corresponding to the first spring or the second spring is a diameter slightly smaller than the first spring or the second spring, and when the first spring or the second spring is compressed and deformed in a normal state. The diameter by which the first spring or the second spring can be bowed to prevent deformation without hindering deformation.
Further, the guide member is supported in the vertical direction with respect to the vehicle body so as to be interlocked with the movement of the vehicle parts. In other words, when the first spring or the second spring is elastically deformed by receiving a force in the compression direction, the guide member is accompanied with the elastic deformation, and simultaneously with the vertical movement of the vehicle part or the vertical movement of the vehicle part. It interlocks with the vertical movement while having a time difference. Therefore, even if there is a step in the guide member due to the difference in diameter between the first spring and the second spring, the vertical impact applied from the vehicle body to the vehicle parts is effectively prevented without hindering the elastic deformation of each spring. Can be reduced.

  Further, the present invention is characterized in that the guide member is supported by a movement assisting member in the vehicle body side bracket.

  According to the present invention, since the movement assisting member assists the vertical movement of the guide member, the vertical movement of the guide member accompanying the elastic deformation of the first spring or the second spring becomes stable.

  According to the present invention, in the invention described in claim 2, the movement assisting member is a low friction resin.

  According to the present invention, since the movement assisting member is made of low friction resin and supported on the outer periphery of the guide member, the movement of the guide member in the vertical direction can be stabilized. In this case, it is only necessary to provide the movement assisting member on the vehicle component side bracket, so that a complicated configuration for assisting the movement of the guide member is not required. Therefore, the guide member can be stably moved in the vertical direction easily and inexpensively.

  In the present invention, the guide member is inserted into a low-friction annular member provided between the first spring and the second spring, and the inner diameter of the annular member is larger than the outer diameter of the guide member. And holding the vehicle component side bracket.

According to the present invention, the guide member is inserted through a low-friction annular member provided between the first spring and the second spring. Here, a force that changes the relative positional relationship between the vehicle body side bracket and the vehicle component side bracket may be generated depending on the weight of the load placed on the vehicle body. Even in such a case, since the vehicle component side bracket is sandwiched by the low friction annular member, the guide member and the annular member, and the contact portion between the vehicle component side bracket and the annular member Has low friction and can shift smoothly. Therefore, it is possible to prevent an excessive force from being generated between the guide member and the vehicle body side bracket.
In addition, since there is a predetermined interval between the outer peripheral portion and the annular portion of the guide member, even if the relative positional relationship between the vehicle body side bracket and the vehicle component side bracket changes, the guide member and the vehicle body side bracket Will not interfere.

  The present invention is characterized in that two low-friction annular members are fitted to sandwich the vehicle component side bracket.

  According to the present invention, the annular member is configured by fitting two low-friction annular members. Therefore, the two annular members can be sandwiched and fitted from above and below the vehicle component side bracket. Therefore, the assembly of the guide member, the annular member, and the vehicle component side bracket is facilitated.

  According to the present invention, in a vertical support mechanism for a vehicle component using a first spring and a second spring having different diameters, the bow deformation of the first spring and the second spring against an impact in the vertical direction applied to the vehicle component. Can be effectively reduced without causing them to grow.

The movement assisting member 17b is provided with a hole 17b2 having a diameter substantially the same as the outer diameter of the portion of the pin 16 that is inserted through the first spring 7. The hole 17b2 is set to be substantially concentric with the circular insertion portion 17b1. Since the inner peripheral surface is a low friction member as described above, it slides with low friction on the outer peripheral surface of the pin 16 inserted into the hole 17b2. Accordingly, the pin 16 is allowed to move only in the axial direction of the pin 16 and is restricted from moving in other directions.

The upper surface of the annular iron plate member 19 b is in contact with the lower annular member 20 b, and the lower surface is in contact with the flange portion 16 a of the pin 16.
Accordingly, the contact surface of the upper annular member 20a with the vehicle component side bracket 15 has low friction, allows the upper annular member 20a and the vehicle component side bracket 15 to move, and makes contact with the annular iron plate member 19a. The surface is also low-friction and allows the upper annular member 20a and the annular iron plate member 19a to move.
Further, the lower annular member 20b has low friction on the contact surfaces of the vehicle component side bracket 15, the upper annular member 20a, and the annular iron plate member 19b.

Yes. The annular iron plate member 19 b is held on the upper end surface of the flange portion 16 a of the pin 16.

  The upper annular member 20a and the lower annular member 20b reduce friction between the annular iron plate members 19a and 19b and the vehicle component side bracket 15, and allow changes in the relative positional relationship between them. That is, the contact surfaces of the upper annular member 20a and the lower annular member 20b with the annular iron plate member have low friction, and the contact surfaces of the upper annular member 20a and the lower annular member 20b with the vehicle component side bracket 15 are further reduced. Therefore, the upper annular member 20 a and the lower annular member 20 b can smoothly approach or separate from the pin 16.

  The inner diameter of the upper annular member 20a is set to be substantially the same as the diameter of the hole 15a provided in the vehicle component side bracket 15, and the outer diameter thereof is substantially the same as the outer diameter of the extending portion of the lower annular member 20b.

The guide plate 5c is inserted between the pair of contact members 22e of the unit 22 as shown in FIG.

  The unit 22 includes a unit base 22a, an elastic member 22c, and a contact member 22e as shown in FIGS. The unit base 22a has a plate shape, and left and right end portions are respectively attached to the base vertical member 14d. A pair of upright members 22b are attached to the unit base 22a in an upright state. The pair of upright members 22b are opposed to each other, and a plurality of elastic members 22c are attached to the opposed surfaces.

  The elastic member 22c is made of rubber and has a cylindrical shape as shown in FIGS. A support member 22d is attached to the end of the elastic member 22c. Accordingly, the support members 22d are attached to the upright members 22b via the elastic members 22c, and the pair of support members 22d face each other. A contact member 22e is attached to each support member 22d so as to be able to appear and retract. The contact member 22e has a cylindrical roller body 22e1 and a stat 22e2. The stat 22e2 protrudes from the eccentric position of the roller body 22e1 and is rotatably attached to the support member 22d.

  A guide plate 5c is installed between the pair of contact members 22e as shown in FIG. The contact member 22e is rotated with respect to the support member 22d around the stat 22e2. As a result, the contact member 22e moves toward the guide plate 5c and is pressed against the guide plate 5c. The elastic member 22c is compressed and deformed, and the contact member 22e is urged against the guide plate 5c by the elastic force of the elastic member 22c.

  The front and rear support mechanisms 2c are located at the four corners of the mounting base 14 shown in FIG. 4 (four corners of the control panel unit 1 shown in FIG. 3). The front / rear support mechanism 2c has a sliding plate 5f shown in FIG. 3 and a protruding member 23 shown in FIG. The sliding plate 5f is made of stainless steel or the like and is attached to the plate member 4g as shown in FIG. As shown in FIGS. 4 and 7, the protruding member 23 has a main body 23a and a liner 23b attached to the end of the main body 23a. The main body 23a protrudes toward the control panel unit 1 from the base vertical member 14d. The liner 23b is made of a material that can be elastically deformed, and is slidably contacted with the sliding plate 5f.

  The third room 1c shown in FIG. 2 is formed in the same manner as the second room 1b. The support device 2 is also provided between the rear surface of the third chamber 1c and the second mounting base 14b. Therefore, the front and rear sides of the control panel unit 1 are supported by the vehicle body 10a by the support device 2.

Next, the operation of the vertical support mechanism 2a according to the first embodiment will be described.
When the vehicle is traveling, a downward impact is generated on the vehicle body 10a, and when the control panel unit 1 moves relatively upward with respect to the vehicle body 10a, the first spring 7 is compressed and deformed to reduce the impact. obtain. At this time, the pin 16 moves upward in conjunction with the upward movement of the control panel unit 1. Also, the pin 16 moves relatively upward with respect to the upper vehicle body side bracket 14g and the lower vehicle body side bracket 14h. In this case, since the upper body side bracket 14g and the lower body side bracket 14h are provided with the movement assisting members 17a and 17b with low friction resin, they are supported with respect to the outer periphery of the pin 16, so the pin 16 The upward movement is stably guided with low friction.
Therefore, the pin 16 moves in conjunction with the movement of the control panel unit 1, and moves to the upper vehicle body side bracket 14g and the lower vehicle body side bracket 14h with low friction.
Further, when the first spring 7 is compressively deformed, the direction in which the force is applied does not coincide with the direction in which the first spring 7 is deformed, and an attempt is made to deform in a bow shape. However, at this time, the inner side of the first spring 7 and the outer peripheral portion of the first spring portion 16a of the pin 16 are in contact with each other to assist the normal elastic deformation of the first spring 7 and prevent the bow deformation.

On the other hand, when an upward impact is generated on the vehicle body 10a and the control panel unit 1 is moved downward relative to the vehicle body 10a, the second spring 8 is compressed and deformed to reduce the impact. At this time, the pin 16 moves downward in conjunction with the downward movement of the control panel unit 1. Also, the pin 16 moves relatively downward with respect to the upper vehicle body side bracket 14g and the lower vehicle body side bracket 14h. Since the upper body side bracket 14g and the lower body side bracket 14h are provided with movement auxiliary members 17a and 17b which are low friction resins, the downward movement of the pin 16 is guided with low friction. . The second spring 8 also tends to be deformed like a bow without being coincident with the direction in which the force is applied when compressively deforming. However, at this time, the inner side of the second spring 8 and the outer peripheral portion of the second spring portion 16b of the pin 16 are brought into contact with each other to assist the normal elastic deformation of the spring and prevent the bow deformation.
Note that the pin 16 is not only interlocked simultaneously with the vertical movement of the control panel unit 1, but may be interlocked with the vertical movement while having a minute time difference from the vertical movement of the control panel unit 1 due to inertia or the like.

Thus, the pin 16 has different diameters of the first spring 7 and the second spring 8, and the outer diameter of the pin 16 is changed to the first spring 7 and the second spring 8 in order to cause normal elastic deformation thereto. The diameter of the pin 16 is slightly smaller than that of the pin 16, and a step is generated in the outer diameter of the pin 16. However, since the pin 16 is configured to be interlocked with the movement of the control panel unit 1, the pin 16 does not hinder the elastic deformation of the first spring 7 and the second spring 8. Therefore, the impact can be efficiently reduced without causing bow deformation of the first spring 7 and the second spring 8 with respect to the impact in the vertical direction applied to the control panel unit 1.
Further, since the upper body side bracket 14g and the lower body side bracket 14h are provided with movement assist members 17a and 17b made of a low friction member such as resin, the pin 16 is guided in the vertical direction while being guided by the movement assist members 17a and 17b. Move smoothly. Therefore, the movement of the pin 16 in the vertical direction becomes stable.
Further, the movement assisting members 17a and 17b have a structure in which a resin is molded, and it is only necessary to provide the molded resin in the upper vehicle body side bracket 14g and the lower vehicle body side bracket 14h, so that the movement of the pin 16 in the vertical direction is assisted. It does not require a complicated configuration. Therefore, the pin 16 can be stably moved in the vertical direction with a simple and inexpensive configuration of resin.

Next, an operation when a heavy load is placed on the vehicle body 10a will be described.
When a heavy load is placed on the vehicle body, the vehicle body 10a bends. As a result, the vehicle body side brackets 14g and 14h may be deformed so that the lower end of the support device faces in the direction opposite to the vehicle component side, as indicated by the broken line in FIG. In FIG. 2, only the rear side is shown, but the same deformation occurs in front of the vehicle body 10a.
As shown in FIG. 2, when the lower end is deformed to face in the direction opposite to the control panel unit 1 side, the control panel unit 1 remains in a horizontal state, so that the pin 16 is in relation to the control panel unit 1. Will be inclined. That is, it inclines between the annular iron plate members 19a and 19b, the upper annular member 20a and the lower annular member 20b, and the upper vehicle body side bracket 14g and the lower vehicle body side bracket 14h. When an impact occurs on the vehicle body 10a, the pin 16 moves in conjunction with the movement of the control panel unit 1 in an inclined state. At this time, since the pin 16 is in an inclined state, the annular iron plate members 19a and 19b and the upper annular member 20a and the lower annular member 20b that are inclined together with the pin 16 remain in a horizontal state. Stress is applied to a certain upper vehicle body side bracket 14g and lower vehicle body side bracket 14h. However, since the upper annular member 20a and the lower annular member 20b are low-friction members, the contact surfaces of the annular iron plate members 19a and 19b with the upper annular member 20a and the lower annular member 20b and the upper annular member 20a and The contact surfaces of the lower annular member 20b, the upper vehicle body side bracket 14g, and the lower vehicle body side bracket 14h have low friction, and the respective positional relationships can be smoothly shifted.
Further, a predetermined gap S is provided between the outer peripheral portion of the pin 16 and the upper annular member 20a and the lower annular member 20b as shown in FIG. Since the predetermined gap S is thus provided, even if the pin 16 is inclined with respect to the control panel unit 1, the pin 16 and the vehicle side bracket, more precisely, the upper annular member 20a and the lower side There is no interference with the annular member 20b.
The upper annular member 20a and the lower annular member 20b are fitted to each other. As a result, the vehicle component side bracket 15 can be gripped and fitted with the upper annular member 20a and the lower annular member 20b sandwiched therebetween. Therefore, it is easy to assemble the pin 16, the upper annular member 20a, the lower annular member 20b, and the vehicle component side bracket 15 when the vertical support mechanism 2a is assembled to the vehicle body 10a.

The above embodiment is not limited to the above, and may be modified as follows.
In the embodiment, it has been described that the vehicle component is the control panel unit 1, but there is no particular limitation as long as it is a member that should not transmit an impact from the vehicle body.
In the embodiment, the first spring 7 and the second spring 8 are described as examples of compression springs, but may be tension springs.
In the embodiment, the movement assisting members 17a and 17b have been described by taking the resin of the low friction member as an example. However, the movement assisting members 17a and 17b may be anything that smoothes the movement of the guide member in the vertical direction. It is not limited to resin members. For example, bearings may be provided on the vehicle body side brackets 14g and 14h.
In the embodiment, the case where the upper body side bracket 14g and the lower body side bracket 14h are a pair of upper and lower parts and the vehicle part side bracket 15 is a single part has been described as an example, but the vehicle part side brackets are a pair of upper and lower parts. May be.
In the embodiment, the first spring 7 is disposed on the lower side and the second spring 8 is disposed on the upper side, and the diameter of the first spring 7 is larger than that of the second spring 8. The arrangement of the one spring 7 and the second spring 8 may be reversed, and the diameter of the first spring 7 may be smaller than the diameter of the second spring 8. In short, each spring may be set so as to have a spring constant capable of receiving the weight of the control panel unit 1.
