Fig. 2 is the structure chart for the body hinge that the utility model one embodiment provides.

Specific embodiment

The utility model is further described in detail below in conjunction with specific embodiment and attached drawing.It is only intended in detail The thin specific embodiment for illustrating the utility model, does not generate any restrictions, the protection of the utility model to the utility model Scope is subject to claims.

With reference to Fig. 2, the utility model proposes a kind of body hinge, including：

Car body component 1, door components 2, cushion device 3 and fastener 4；

Car body component 1 includes at least two branch gripping arms 11 being oppositely arranged, connectionless, car door portion between two branch gripping arms 11 Part 2 includes at least linking arm 21, and the width of linking arm 21 is more than the distance between two branch gripping arms 11, and door components 2 are with supporting Cushion device 3 is installed, fastener 4 is through hole, the hole of cushion device 3 and the two branch gripping arms on door components 2 between arm 11 Hole on 11 tightens together multiple components.

Fig. 1 show the structure chart of body hinge of the prior art.

Body hinge of the prior art is made of car body component A1, door components A2, bushing A3 and axis pin A4, vehicle body There are 2 branch gripping arm A11 in components A 1, maintained a certain distance between two branch gripping arm A11, to accommodate door components A2, vehicle Door part A2 by axis pin A4 by riveting fixed to car body component A1 two branch gripping arm A11 between, door components A2 with Bushing A3 is installed at axis pin A4 matching holes, can so ensure that door components A2 is smoothly rotated around axis pin A4.In vehicle body Between two branch gripping arm A11 of components A 1, the limiting section A12 of car body component A1 is connected to, door components A2 is selected around axis pin A4 When, the limiting section A12 of the limiting section A21 and car body component A1 of door components A2 are contacted, and play the function of hinge angle /V.By In car body component A1 be molded by plate stamping, and the presence of limiting section A12 causes its stamping material embryo larger, waste material compared with More, cost is larger, and limiting section A12 also adds the weight of hinge in itself.

In the present embodiment, body hinge is redesigned, car body component 1 includes at least two branch being oppositely arranged Gripping arm 11, connectionless between two branch gripping arms 11, door components 2 include at least linking arm 21, and the width of linking arm 21 is more than two The distance between a branch gripping arm 11 eliminates the limiting section connected in the prior art between two branch gripping arm A11 in the present embodiment A12, so that the weight saving of body hinge, makes door components 2 be installed on the outside of two gripping arms 11 of door components 1, institute With when door components 2 are with 1 relative rotation of door components, the linking arm 21 on door components 2 is as limiting section and car body component 1 The upper sides 12 of two branch gripping arms 11 be in contact, so as to play limit function, the upper side 12 of branch gripping arm 11 plays automobile body part The limiting section function of part 1.

Body hinge provided by the embodiment due to eliminate in the prior art connect two branch gripping arms between limiting section, from And make the weight saving of body hinge；Since car body component 1 has subtracted the limiting section between branch gripping arm in the prior art, make entirety Punching press material base size greatly reduce, waste material is made also to reduce, so as to reduce the cost of product；New structure design cuts with scissors car door The limit function normal work of chain.

In one of which embodiment, the hinge limit structure of car body component 1 is the upper side 12 of two branch gripping arms 11 Or the hinge limit structure of car body component 1 is mounted on the upper side 12 of two branch gripping arms 11.

By the use of branch gripping arm 11 upper side 12 as the hinge limit structure of car body component 1, make additionally set hinge Chain position limiting structure；By the hinge limit structure that car body component 1 is installed on the upper side 12 of branch gripping arm 11, it is only necessary to using very Few punching press material base can be completed.

In one of which embodiment, the hinge limit structure of door components 2 is linking arm 21 or door components 2 Hinge limit structure is mounted on linking arm 21.

By the use of the linking arm 21 of door components 2 as hinge limit structure, make additionally set hinge limit structure； By setting hinge limit structure on linking arm 21, it is only necessary to can be completed using seldom punching press material base.

In one of which embodiment, cushion device 3 is bushing.

Cushion device 3 is when may wear to a certain extent, it is necessary to replaced, and bushing is easy to process, at low cost, easily It replaces.

In one of which embodiment, fastener 4 is axis pin.

Axis pin is the fastener of a kind of standardization, both can static state be fixedly connected, can also do relative motion with connected piece, it is main The hinged place of two parts is used for, forms hinge connection.Convenient disassembly is made as fastener using axis pin, and is fastened more firm Gu.

In one of which embodiment, on the hole and two branch gripping arms 11 in hole, cushion device 3 on door components 2 Hole is circular hole.Hole is designed as circular hole makes multiple components be more prone to fasten in fastening.

In one of which embodiment, car body component 1 is mounted on the vehicle body main body of vehicle, and door components 2 are mounted on vehicle Car door on.By the way that car body component 1 to be mounted on to the vehicle body main body of vehicle, door components 2 are mounted on the car door of vehicle, make Both body hinge connections.

With reference to Fig. 2, in one of which embodiment, body hinge includes：Car body component 1, door components 2, pad dress Put 3 and fastener 4；Car body component 1 includes at least two branch gripping arms 11 being oppositely arranged, connectionless between two branch gripping arms 11, Door components 2 include at least linking arm 21, and the width of linking arm 21 is more than the distance between two branch gripping arms 11, door components 2 Cushion device 3 is installed between branch gripping arm 11, fastener 4 through on door components 2 hole, the hole of cushion device 3 and two Hole in branch gripping arm 11 tightens together multiple components；Wherein cushion device 3 selects bushing, and fastener 4 selects axis pin；Vehicle body The hinge limit structure of component 1 is the upper side 12 of two branch gripping arms 11, and the hinge limit structure of door components 2 is linking arm 21, the hole on door components 2, the hole on the hole and two branch gripping arms 11 of cushion device 3 are circular hole.

The present embodiment has saved product cost, alleviates product weight, while also makes the limit function of body hinge normal Work.

Above-described is only the principle and preferred embodiment of the utility model.It should be pointed out that for the general of this field For logical technical staff, on the basis of the utility model principle, several other modifications can also be made, also should be regarded as this practicality New protection domain.
